Description

[0001] PLASTIC PROFILED SEMI-RIGID BARRIER No. 3 having the basic aim together with barriers No. 1 and No. 2, from the basis patent, to protect permanently old buildings and monuments - monuments of cultural value, from destructive effects of capillary moisture. The barriers are installed into the damp walls after the partial cutting, while neither the stability nor the construction of the building is endangered. The subsequently installed barriers represent a new damp-barrier, a new horizontal hydroisolation and they completely prevent capillary moisture penetration through porous walls of old civil engineering structures.

[0002] The connection with the Basic International Patent No. EPO1042565, and in the Republic of Serbia Patent No. 49324, registered in the Patent Register at the Institute for Intelledual Property.

PRODUCT, PROCEDURE AND INSTALLATION OF BARRIER NO. 3

[0003] THE FIELD OF TECHNICAL APPLICATION the invention relates to:

• civil engineering,
• rehabilitation of old and wet buildings affected by capillary moisture. Such buildings, as a rule, in their foundation part of walls, have no any horizontal hydroisolation or it is completely destroyed by time,
• rehabilitation and preservation of monuments of historical and cultural value - cultural real estates
• protection of old building from capillary moisture and groundwater,
• post-constructional fitting of new waterproof barrier,
• post-constructional establishment of new damp-proof course for control of wall moisturizing by capillary and osmotic forces,
• machine cutting of massive and very massive walls which thickness is often two, three or more meters. In such cuts we insert a new damp-proof barrier, plastic profiled semi-rigid Barriers No. 1 or No. 2 and No. 3 to prevent capillary moisturizing.

THE UNITY OF INVENTION

[0004] This invention (BARRIER No. 3.), is connected to the basic patent No. EPO1042565 and in the Republic of Serbia patent No. 49324 which is registered in the Patent Register at the Institute for Intellectual Property.

[0005] In walls rehabilitation endangered by capillary moisture by cutting method, the applied rule is that and additional horizontal hydroisolation is always installed at the level of the building floors, or at the height that does not exceed 5-6 cm above the floor peak elevation.

[0006] In practice with the rehabilitation of old buildings (churches, monasteries) the floors are often made in several different levels. This is a special problem when we rehabilitate massive and very massive walls with the thickness often 50, 70, 200 and more centimetres. How to rehabilitate such massive walls and at the same time to adapt the horizontal hydroisolation to different floor levels? How in such massive walls to cascade, "to break", the horizontally made hydroisolation and to adapt it to different floor levels?

[0007] BARRIER No. 3, solves very easily and simply the problem of cascade connection of two, three and more different levels of horizontal hydroisolation.

[0008] According to MKP (7) the subject of the invention can be classify into class: E 04 B 1/62; E 04 F 21/00; E 04 G 9/10: E 04 G 23/06.

TECHNICAL FIELD (BARRIER No.3)

[0009] The technical problem which did not solve the basic invention (BARRIER No. 1 and BARRIER No. 2) aswell as the procedure of installation of these barriers, was that the mutually connected barriers, whether Barriers No. 1 or No. 2 were in question, could be installed only through horizontal, i.e. straight made cuts. The reason why the walls in massive buildings of old civil engineering structures are cut exclusively through horizontally made cuts is the prevention of the possibility of cut wall demolition by shear (if the cut would be made under the acute angle - there is the real danger that the building will collapse).

[0010] The procedure of making straight and flat cuts (a new horizontal hydroisolation) and the installation of Barriers No.1 and No.2 is indicated by the basic invention (EPO1042565).

[0011] (EPO1042565). Old and wet walls are completely cut at the aimed spot by machine. For preventing the building to settle and the walls not to crack, the cutting is done partially - in kampadas (ribs) (phases).

[0012] Through such made kampadas we install the BARRIERS No. 1 or BARRIERS No. 2, as a new horizontal hydroisolation, i.e. a new waterproof barrier. In this way we have permanently, and once forever, prevented any further penetration of capillary moisture and moistening of buildings.

[0013] Due to aimed characteristics of mutually connected BARRIERS No. 1 or BARRRIERS No. 2, the barriers can be installed exclusively through horizontally made kampades, where the vertical ribs on barriers completely, without any deformations, take over the vertical loading from upper parts of the building. These vertical ribs (which height for each barrier, depends on the cut height is constantly optimised) prevent the characteristic settlement of budding, i.e. the appearance of cracks on treated walls - monuments of culture.

[0014] The problems apppear when there is the question how to connect in a series, - cascades, more different levels of horizontal hydroisolation, and in such a way not to lose the above stated characteristics:

• the combination of mutually connected Barriers No. 1, 2, and 3, must completely prevent the capillary moisture penetration
• after vertically done cascade (Barrier No. 3), the construction of the building must not be disturbed and
• the vertical ribs on Barriers No. 1 and 2 must, without any deformation, take over the vertical loading from the building in order not to crack the cut wall.

[0015] The technical problem that the subject invention solves, is BARRIER No. 3 which very easily and simply solves the problem of cascade bridging as it is indicated on the enclosed figures.

THE STATE OF TECHNIQUE (BACKGROUND ART)

[0016] According to patent and non-patent documentation, it is known that the rehabilitation of civil engineering structures endangered by capillary moisture applies the following methods:

1. HW - Method:

[0017] The rehabilitation procedure of wet wall endangered by capillary moisture is based on direct insertion (driving in) of corrugated prochrome steel sheets as moisture barriers with a vibrating power press. HW-sheets, as horizontal isolation are driving in one by one into the walls exclusively through mortar connections (wall joints). The major disadvantage of this method is that the structure is subjected to serious vibrations by sheets driving in: outstanding damage of its stability and load capacity. Also, the overlaps of HW-sheets are often impossible to make qualitatively, the moisture penetration on joints is possible, the settlement and cracking very expressed, and we have to add the high cost of prochrome sheets. The cascade connection of more levels is not developed.

2 COMER Method

[0018] The wall is cut only at the joints. The cutting is in stages (kampadas) and the cutting width ranges from 20 to 120 cm, cut height from 8 to 14 mm. The cuts are fitted with waterproof material, either bituminous bands, technical PVC foils or plasto-elastic "fibreglass" sheets (made of glass voile and epoxy resin). The bands are cut and placed to overlap for 5-10 cm. To prevent wall subsidence, plastic wedges, (pin or zeppas) are fitted perpendicular to the wall axis as temporary load supports until the injected mortar-plus-additive (expander) blend sets.

[0019] The disadvantage of this procedure is that it does not allow rehabilitation of very massive walls with the thickness that exceeds 130 cm. Nor can it be applied to stonewalls or walls built in brick-and-stone mix.

[0020] Differential structure subsidence and fracturing of treated walls have been frequently observed as a result of fairly poor support of the walls by the inserted zeppas (wedges). The loading of the structure is transferred to the foundation wall only through inserted wedges.

[0021] Some years ago the company COMER developed its own PVC barriers under the commercial name "IGROSTOP". The procedure of product "IGROSTOP" insertion is exactly the same as in the insertion of technical foils. Knocking in the plastic wedges prevents the settlement. The problems with bigger of smaller settlement remains, the cascade connection of more levels of horizontal hydroisolation is not qualitatively solved.

3. UMIBLOK Method

[0022] The method requires horizontal wall cutting in phases (kampadas) 20 to 50 cm wide intervals by self propelled machines, the height of cuts amounts 12-16 mm. The cuts are injected with viscous mortar with additives as: accelerator and expander. This is followed by successive assembling and fitting of UMIBLOK bars. The bars are made of PVC by extrusion on extruder.

[0023] UMIBLOK bars are profiled with acute ribs shaped as letter X of the total height of 6 mm and they have the only purpose, the basic one - to be the waterproof barrier.

[0024] The disadvantage of UMIBLOK bar itself and the procedure (shape, profile and construction), is that its sole purpose is a waterproof barrier - horizontal hydro isolation. The load of the structure above the cut wall is to be supported by the injected mortar.

[0025] Another disadvantage of this procedure is the appearance of hazard microfissuring and a very difficult, slow and complicated work during the installation of bars, due to undefined time of mortar bonding. Additives are used to accelerate bonding and hardening of injected mass. The injected mass prevents the continuity of work and an easy and simple bars installation. The problems with settlement, due to profile shape, are very expressed, they are the same as in COMER. The cascade connection of more levels of horizontal hydroisolation is not qualitatively solved.

[0026] All of the listed problems and disadvantages are successfully solved by applying the new method and product described in these patent documents.

SOLUTION DESCRIPTION (DISCLOSURE OF THE INVENTION)

[0027] The gist of the invention and the method is the Plastic Profiled Semi-Rigid Barrier No.3 - which basic task is to continuously connects in cascades more different levels of horizontally made hydroisolation. Very often in practice during the installation of horizontal hydroisolation in a manner stated in the basis invention

[0028] (BARRIER No. 1 and BARRIER No. 2) due to different floor levels, it is necessary to connect two or more levels of horizontally done hydroisolation.

[0029] In accordance with the basic invention (BARRIER No. 1 and BARRIER No. 2) the walls are cut in small kampadas and in such horizontal cuts we install one after the other BARRIERS No. 1 and BARRIERS No. 2 up to the aimed spot where the cascade has to be done. The last kampada in horizontal line is finished with the installation of BARRIER No. 3. ON THE AIMED SPOT we start to make a cascade by vertical cutting. In such cut we install BARRIER No. 3 as a cascade (patent request).

[0030] After the done bridging and vertically done cascade the horizontal cut continues by installation of BARRIER No. 1 or BARRIER No. 2.

[0031] The transfer to the new horizontal plain is made by new horizontal cuts continuing the procedure characterized by the basic invention.

[0032] Plastic Profiled Semi-Rigid Barriers No. 1, 2, and 3 in fact solve 3 (three) problem:

a) once fitted into the wall cut it represents a new unique horizontal waterproof barrier - additionally installed horizontal hydroisolation,

b) prevents the structure settlement, and

c) simply, easily and completely safe cascade connection of more levels of additionally installed horizontal hydroisolation.

The procedure of BARRIERS 1, 2, and 3 installation is as follows:

1. CUTTING

[0033] 

• The cutting is done in kampadas not wider than 20-30 cm. The cutting is done through the determined centre line - the aimed spot. The height of centre line relating to the floor peak elevation depends on the kind and scope of other works on the structure. The aimed spot, i.e. the centre line through which the cut passes is usually at the floor plain or 4-6 cm above the floor peak elevation.
• Each individual kampada can have different cut height (CH) depending on the cutting tool: 8,00; 9,00; 10,00; 11,00; 12,00 and 14,00 mm.
• Wet walls (capillary moisture) are cut on the aimed spot in one of the two ways:
  • Widia or diamond cutting chain for walls built with bricks in lime mortar by electric or hydraulic machines where cutting is exclusively done through mortar connection - joint, and
  • by diamont cutting chain (diamond wire) (diamond wire-saw) for walls of stone or mixed material (brick+stone) with hydraulic machines regardless of joints.
    (FIGURE 1.)

2. HEIGHT DETERMINATION (h1) OF VERTICAL RIBS ON BARRIERS No. 1 2 and 3

[0034] The height of the rib (h1) of each individual barrier completely depends on the total height (CH) of each individual kampada. For each kampada barriers are separately prepared with corresponding ribs height (h1).

[0035] The height (CH) of each individual kampada is a changeable value. It is different for each individual kampada and depends on many factors: kind and diameter of cutting tool, kind of material the structure is built (stone, brick, unbaked brick, air brick), wall compactness, coherent-non-coherent wall material, condition of walls that are cut, wetter or less wet, dry, etc.

[0036] In order the walls not to crack and the structure not to settle, the installed barriers must be self-encoring, (self-lifting), i.e. each barrier must have its own height (h1). It is realized so that (CH) of each individual kampada is precisely measured, a value (Δh1) (which is usually Δh1= 0,10-0,20 mm) is added.

[0037] THE ESSENCE OF THE BASIC PATENT IS: to optimise the height of ribs on plastic semi-rigid profiled Barriers No. 1 and No. 2 by precise grinding according to the cut height for each individual kampada. The barriers themselves prevent settlement of the structure (+Δh1) by their construction, and vertical ribs take over the complete vertical loading without any deformations.

[0038] The patent is characterized so that each barrier must have, after the optimisation, the stated value:


so that the structure is completely protected from settlement.

• h1    the total height of each individual barrier after adjustment,
• CH    total cut height (kampada),
• Δh1=0,10-0,20 mm    in order the barrier to be self encoring (self-lifting and must have this aimed value.

[0039] CAPACITY OF THE BARRIER. Each barrier over its vertical ribs, immediately after the installation, takes over the vertical loading from upper parts of the structure without any deformation.

[0040] The barrier is so designed that it can withstand unit loading of any structure, with its profile shape, number and arrangement of vertical ribs, dimensions, even on dry (without injected mass). The average strength to pressure only for the barrier amounts 11,20 MPa and in the combination with hardened injected mass 42,00 MPa.

3. MASS FOR INJECTION

[0041] In such made cuts we inject, with the pump under high pressure (30 bars) and needle for injection, the viscous cement-polymer mass with additives: plastificator, expander and retarder. The mass for injection fills in the whole kampada (CH).

[0042] The consistency of the injected mass is very important. The injected mass within the cut itself must have the plastic consistency at least another 3 hours after filling in order to be able to install easily the barriers. The injected mass is also waterproof barrier. It completely fills in the kampada and the whole profile of the barrier and hardly bonds the barrier by adhesion, after the finished polymerisations, with the upper and lower surface of the cut, making in such a way a new, monolith and waterproof connection (joint) in the wall;

[0043] 4. Through this viscous mass with the slow blows of the hammer we install one by one the plastic profiled semi-hard Barriers No. 1, 2 or 3 which heights are previously precisely grinded and optimised according to the cut height (CH).

[0044] Mutual connection of barriers is possible by male coupling (MC) and female coupling (FC). Barriers independently by its construction prevent the settlement of the structure where the vertical ribs completely take over the vertical loading without any deformation. According to that the combination of carrying capacity of the barrier itself and the injected mass completely change the old mortar connection (joint).

EXAMPLE

[0045] The mutual cascade connection of two or more levels by horizontal hydro isolation (BARRIERS No. 1 and 2.) (the basic patent) - by cascade (BARRIER No. 3) (PATENT REQUEST) -

1. Cutting and injecting of cement-polymer mass, installation of barrier No. 1, 2 and 3

[0046] 

(FIGURE 2, 3, 4, 5, 6 and 7)

[0047] We take as an example a wet wall made of bricks in lime mortar. The thickness of the wall (th) is th= 130 cm. The cutting of the wall is made by diamond cutting cable through the mortar connection (joint). The height of the cut (kampada) is CH=10 mm.

[0048] The cutting is in phases, in kampadas of 20-30 cm width. After the opening of the kampada, the cut is mechanically deaned from dust and fall off brick particles and mortar.

2. Preparation and installation of plastic profiled semi-rigid barrier No.1 and No. 2 (the basic patent)

[0049] 

plastic profiled semi-rigid Barriers No.1 and No. 2 have the following dimensions:

W

width of the barrier,

X

length of the barrier (can be unlimited),

h1

height of the optimised barrier

CH

cut height

h

original factory barrier height. It is constant and is h=14,00 mm

[0050] In the example we have stated that the cut height is CH=10 mm and the thickness of the wall (th)=130 cm. From a long piece X we cut the barrier of length (I) 11=140 cm, (11=th+5+5 *cm). Each barrier must be individually prepared before installation.

[0051] The factory (the manufacturing) barrier height (height of ribs) is h=14 mm.

[0052] In order to get the rib height (h1), factory rib height (h) must be brought to the certain measure (h1) by precious grinding. Barrier grinding (thinning of the ribs) is done by a special machine where the new height, the height of the barrier (ribs) (h1) is optimised for each kampada separately.

[0053] The height (h1) of each individual barrier is designate by formula:


where:

• h1    the total height of each individual barrier

• CH    the total cut height (kampada)

• +Δh1=0,20 mm    in order the barrier to be self encoring, (self lifting) it must have this assigned value

I

[0054] n a deaned kampada of height CH=10,00 mm we inject, with a pump under the high pressure (30 bars) and needle for injection, the viscous cement polymer mass. Through the injected mass with the slow blows of the hammer we install one after the other barriers with height of h1=10,20 mm.

[0055] The complete procedure of cutting, deaning, injection, preparation and the installation of barriers is continuous, so that a quick rehabilitation even with very massive walls is very impressive.

[0056] The invention is shown in details on the figures as follows:

FIGURE No. 3, presents prefabricated plastic profiled semi-rigid Barrier No.1

[0057] Plastic profiled semi-rigid Barrier No. 1 is made by extrusion on the extruder and it represents in fact the PVC-polyvinylchloride (hard) with different additives for the improvement of mechanical characteristics: hardness, strength, breaking, resistance to stroke, elasticity, waterproofing, resistance for improvement to different chemical agents, (acids, bases, salts), for neutralization of thermical influences and UV-stabilizer for greater resistance to ultra violet radiation.

FIGURE No. 5, presents prefabricated plastic profiled semi-rigid Barrier No.2

[0058] Which according to the composition of material, chemical, physical and mechanical characteristics is identical to Barrier No. 1. The difference is only in design of FC profile which in Barrier No. 2 is semi-open sphere SF. Female coupling FC in Barrier No. 2 is much stronger and more robust. Since the barriers are extruded on the extruder their length X can be unlimited.

FIGURE No 6, presents prefabricated plastic profiled semi-rigid Barrier No.3

[0059] Which according to the composition of material, chemical, physical and mechanical characteristics is identical to Barriers No. 1 and 2 from the basis patent.

[0060] BARRIER No. 3 is essentially different from Barrier No. 1 and 2, first of all according to the total width W3, number of ribs and the design of FC profile which is as in the Barrier No. 2 semi opened sphere SPH, but it is rotated for 90° relating to the axial axis of Barrier No. 3.
The essential difference of Barrier No. 3 and Barrier No. 1 and 2 (the basic patent) - is in its characteristic purpose. BARRIER No. 3 has the exclusive purpose to bridges in cascades two or more levels of horizontal hydroisolation.

[0061] Since the Barriers No. 1, 2 and 3 are extruded on the extruder their length X can be unlimited.

[0062] The plastic profiled semi-rigid Barriers 1, 2, and 3 which have the profile, shape, size, number, height, thickness and spacing of the ribs, R, are designed so that the ribs R can assume the total vertical load of the structure above the cut without any deformation and at the same time during barrier fitting, they can also, with their profile, allow unobstructed penetration through the injected campadas.

[0063] The Plastic Profiled Semi-Rigid Barrier No. 1 and 2 (Figs. 1, 2, 3, 4, and 5) are both designed and made so that both barriers have the same length X. The length X can be infinite. The barriers consist of a horizontal plane plate denominated a; their total width is W, their wall thickness th. For the barrier to support the vertical load of the cut wall, the horizontal plane of the plate a is intersected with a sufficient number of vertical ribs, R, at S intervals or spacing.
Wall thickness, th, is identical to the thickness of plate a. Total rib height is h. Rib spacing, S, and wall thickness, th, are variables in function of the calculated load and static calculation and can be changed.

[0064] Plastic Profiled Semi-Rigid Barriers No. 1 and 2. are mutually interconnected and laced one into the other via male and female couplings MC and FC, respectively to form a permanent and unbreakable tie.

[0065] The male coupling, MC, for all three Barriers No. 1, 2 and 3 is completely the same, and is a cylinder, C; its diameter is denoted d. Cylinder C is an integral part of the horizontal plate, a, so that the plain of the horizontal plate makes the whole.

[0066] The female coupling FC, - depends on the barrier type - it can be:

1. BARRIER No. 1, a female coupling FC in case of the Plastic Profiled Semi-Rigid Barrier No. 1 (Fig. 2 and 3) is a semi-open, rectangular, (pentagonal) box profile of infinite length X. Box profile is from one of its side monolithly made and connected to the barrier body (it is unintenupted connected to the plane of horizontal plate a. The other end has two inward bent, semi-open claws, Cl. The clearance, c, between the tips of the claw, Cl, corresponds to the diameter, d, of the cylinder C, increased for +0.50 mm (c = d + 0.50 mm). The distance between the tips, c1, of the semi-open claw, Cl, corresponds to the barrier wall thickness, th, increased for +0.50 mm (c1=th+0.50 mm). These tolerances completely satisfy and justify both set targets: easy coupling of male and female coupling MC/FC and unbreakable connection.

2. BARRIER No. a female coupling FC in the case of the Plastic Profiled Semi-Rigid Barrier No. 2 (Fig. 4 and 5) is a spherical (SPH) semi-open box profile of infinite length X. Spherical semi-opened box profile SPH is from one of its side monolithly made and connected to the barrier body (it is uninterrupted connected to the plane of horizontal plate a, and from the other side it ends with two semi-opened, inward bended daws of sphere CSPH. The diameter d1 of the SPH sphere corresponds to the diameter, d, of the cylinder, C, increased for +0.50 mm (d1=d+0.50 mm). The clearance, c1, of the SPH semi-open sphere corresponds to the barrier wall thickness, th, increased for +0.50 mm (c1=th+0.50 mm). These tolerances completely satisfy and justify the two targeted functions: the easy connecting of MC and FC and at the same time it makes that the connected barriers are unbreakable connection.

3. BARRIER No.3 Female coupling (FC) of the Plastic Profited Semi-Rigid Barrier No. 3, (Fig. 6 and 7) is the same in the profile, shape and dimension as the female coupling (FC) on Barrier No. 2. The essential difference of these two female couplings (FC) is the different purpose for which these two barriers are designed:

1. Barriers 1 and 2	MC/PC have the basic aim to connect mutually and unbreakable the series of Barriers No. 1 or No. 2 and can be installed exclusively as flat horizontal hydroisolation surfaces, and
2. Barrier No. 3	FC is rotated for 90° in relation to axial direction of horizontal plane plate a and FC in Barrier No. 3 enables cascade connection of two or more levels of hydroisolation barriers No.1 or No. 2
