• Construction of prefabricated parts in shop to be assembled in situ as well as engineer works and edifices.

[0003] A particular object of the invention is the design of a structure that can be used in different areas of the construction sector, based on polymeric material solid supports and in alternative materials to polymeric ones such as concrete blocs, ceramic elements' parts, and granular material.

[0004] A second particular object of the disclosure is the design of a structure that can be used in different areas of the construction sector based on polymeric material sheet supports or an alternative to polymeric materials such as wooden boards, laminated wood, and wooden agglomerates, metallic ones; said sheets separated by prisms or hollow cylinders of polymeric materials; of wood, laminated wood, wooden agglomerates, metallic or carton.

[0005] A third particular object of the invention is the design of complementary parts of the structure such as connectors, wall armatures and connector armatures, based on concrete or cement mortar and steel respectively, and in alternative materials to steel as polymeric materials, other metals, glass and carbon fibers.

FIELD OF THE INVENTION

[0006] The invention is related to a structure and a method for building a structure, that can be used in diverse areas of the construction sector, both in buildings and engineering works, including not only the use of concrete poured into the mold, but also shooting concrete on a support and using alternative materials to concrete or cement mortar in some of its parts.

BACKGROUND OF THE INVENTION

[0007] Use of concrete with steel bars goes back to the end of the XIX century to obtain a composite material having the characteristics of concrete as to its resistance to compression and those of steel, most of all regarding its tensile strength.

[0008] The structural concrete elements are fabricated preparing an enclosure by means of a mold known as formwork with the shape of the desired structural element. Steel armatures are placed in the inside of said mold in the areas and direction supporting traction when said element is overloaded, filling afterwards the enclosure with poured concrete and consolidating it by means of bar chopping or vibration. Once concrete sets in and hardens the mold is removed in the procedure known as stripping.

[0009] The different structural elements can also be prefabricated in shop so that once the concrete hardens they can be transported to the construction site. These prefabricated parts might be lightened boring holes inside them as is the case of hollow slabs. Before pouring of concrete previous tension can be applied to armatures as is the case of pre-stressed concrete parts, or said structural elements may have hollow ducts so that once they are placed in the construction site, cables or steel tendons can be introduced through them to tense them afterwards; an operation known as post-tensing.

[0010] However the need of well designed constructive elements built in situ or prefabricated in shop, thus simplifying work in diverse applications in the field of construction and also saving materials and labor with a resulting relevant economic effect, is increasingly evident.

[0011] Patent GB 2023215 of June 15, 1979 to Luddington Enterprises Ltd. discloses a constructive two-walled reinforced concrete element, built by projecting bars overlapping with the armature mesh of the walls on a two-sheet support, separated by steel bars either horizontal or in a lattice pattern. However, the connection between the two walls is limited by its relatively weak mechanical resistance; it can only be used in surfaces submitted to low stress as in buildings' closures or small bearing walls.

[0012] Document US 3982368 of December 18, 1974 to American Volkscastel International claims a two-walled shot concrete constructive element wherein the cavity between walls is achieved with a wavy carton support sheet. The claimed element has two connectors between walls made up of steel bars overlapping in the armatures of walls. There is another alternative wherein walls are braced by means of concrete partitions provided at a certain distance. The alternative in which bracing between walls is achieved by means of concrete partitions is the one presenting more rigidity, mostly in the direction of partitions while it is scarcely rigid if perpendicularly. The US 3982368 invention is designed for prefabricated panels that are assembled in the metallic frames through bolts to the forging borders. It is designed to build only flat surfaces submitted to low stress as in buildings' closures.

[0013] Document DE 19520082 of June 1, 19955 to Bitttscheidt, Norbert, Datteln, discloses a double-walled prefabricated concrete double-walled lost formwork to build vertical concrete walls packed a posteriori. Formwork is not recuperated as in traditional procedures. The proposed system aims to build solid concrete walls instead of hollow ones. It is useful only in vertical surfaces, needing a significant amount of concrete. ES 2163938 discloses a structure with two or more concrete walls connected by other elements of the same material and a process to manufacture the same.

[0014] Thus the need of an innovative solution having adequate stiffness in all directions, able to be used in the construction of any surface, even those requiring high resistance requirements as to stress. It should equally be versatile enough so it can be used in the construction of prefabricated panels as Perriin's, but also to build in situ any surface or edifice; building any surface even with curvature as in vaults, domes or any warped surface, allowing for variable separation between walls allowing adaptation in each point according to required stress level of said point.

DESCRIPTION OF THE INVENTION

Features of the present surface generating module

[0015] The present invention provides a structure according to claim 1 and a method according to claim 9. Various optional features are set out in the dependent claims. The structures of the invention used in a given construction have some features previously mentioned providing at the same time inventive, novel features with respect to the state of the art.

[0016] In the first place, contrary to normally used art in structure design wherein said structures are made up of linear elements, the ones built according to the invention are made up of elements of a mainly superficial character. Superficial dimensions of surfaces built using the invention are clearly superior as to their thickness.

[0017] At the same time the concept of formwork to configure an enclosure in which concrete is poured disappears, using in this case a support to shoot concrete or mortar on both faces of same. The support is not necessarily removed but it may be left inlayed in the surface. Thus it results in a very light element for surface building wherein concrete or mortar is placed only in areas of compression stress originated by structure loading and to cover steel bars supporting tensile stresses.

[0018] All types of structural elements and shapes can be made by the invention, either superficial ones as slabs, floor slabs, floors, brackets, vaults, water deposits, contention reinforced walls, bearing walls, closures, partitions, bridge boards, as well as linear structural elements as pillars, bridge piers, beams, girders; also volumetric structural forms as gravity dams o vault dams for water reservoirs.

[0019] The present structure comprises at least two reinforced concrete or mortar walls, although they can also be made of reinforced cement mortar, coupled by connectors at a certain distance, which are generally of the same material, or of polymeric material; metallic, wooden; carbon fibers reinforced resin, glass fibers reinforced resin; or any other type of material with sufficient mechanical strength according to requirements of the constructive object to be built.

[0020] As main innovative feature of the structure of the invention is the fact that it increases the inertia momentum of a surface regarding its medium plane, by separating walls from each other without increasing construction material requirements, as is the case of formwork concrete elements, wherein to increase momentum of inertia, thickness of surface has to be increased generating more material consumption, labor and time. Thus, the present invention provides very resistant structures with a much lower use of resources. Structures built according to this invention are much more resistant to seismic movement stresses. All of this results in an important saving of resources, rendering a significant applicability and an important economic effect.

Building procedure

[0021] The following is an example of a method to build a structure using a solid support.

a) Preparation of support as to dimensions and location of surface to be built. The support should be made up of light material, easily moldable, cut and drillable.

b) Bores are bored in said support with the dimensions and shapes of connectors used to join the walls. The bore section coincides with that of the future connector and its depth with the connector's length.

c) Armatures of future connectors are introduced through bores of the support. Armatures carry ends to overlap with wall armatures.

d) Armatures of each future wall are attached and fixed to each face of support.

e) Ends of connectors' armatures are folded and overlapped or welded with armatures of walls.

f) Once all armatures are placed and overlapped on the support and said support is correctly placed according to the shape of the surface, concrete or mortar is shot beginning by filling bores and thus forming connectors, then

g) Concrete or mortar is shot against one of the support faces covering armature and providing required thickness, thus forming one of the walls.

h) Concrete or mortar is shot on the other face of the support covering the corresponding armature, forming the second wall.

[0022] If the construction is three-walled, operations previously described are repeated except for folding of the ends of connector armatures in the face wherein the third wall is to be built. Next a second support is attached to the wall already built with bores facing salient ends of connectors' armatures so that the ends, once the second support is placed, protrude through its bores. Next armatures of second wall are placed. Protruding ends of armatures of connectors are folded and overlapped with those of the third wall and concrete or mortar is shot beginning by filling bores of second support, and next on seen face of second support, covering armatures and thus forming the third wall. If the structure of the invention has more walls the operation is repeated until completion of all walls.

[0023] Alternatively, connectors can be prefabricated in shop instead of in situ as previously described. In this case, these are cylinders or prisms of reinforced concrete or mortar with two or four parallel bores close to both bases of said elements. Once in the construction site they are introduced in the support bores. Wall armatures are placed at both faces of support and tying bars overlapping with armatures of future walls are introduced through connectors' bores. Tying bars introduced in connectors should be impregnated with resin so that they adhere to the concrete or mortar of connector's bores along their contact surface. Once all prefabricated connectors and armatures of both walls have been placed, concrete or mortar is shot on one face of the support, thus forming the first wall and afterwards concrete or mortar is shot on the other face of the support thus forming the second wall.

[0024] It is also possible to make up a surface according to the invention when there is no access to one of the surfaces to be built, by preparing a first support without bores with the shape of the future surface; this first support can even be the embankment of an excavation and if so, a first wall armature and connectors' armatures are placed in this support. Next concrete or mortar is shot thus forming the first wall; afterwards a second support is attached to this first wall, being said support solid or a non-claimed double-sheet support. Bores of this second support are arranged so that when attaching same to the already built wall, connectors' armatures are introduced through the bores protruding from them. Next armatures of second wall are placed, folding and overlapping ends of connectors' armatures with armatures of second wall, shooting concrete or mortar, filling bores and covering armatures of second wall, thus finishing same.

[0025] When the second wall of concrete or mortar of the invention is to be used as reinforcement of an existing structure, instead of demolishing said wall and building a new one whether it is damaged or deteriorated, or a change of use is desired to increase for example, its loading capacity; the reinforcement method is as follows:

a) First the structure is tubbed so that work can be carried out safely since the actual structure acts as support for shooting of concrete or mortar.

b) According to reinforcement design, a series of bores are bored in all the surfaces to be reinforced.

c) Connectors' armatures are introduced through these bores

d) Next, armatures corresponding to each wall are fixed in each face of the surface to be reinforced.

e) Connectors' armature ends are folded in each face of the surface, overlapping them with corresponding armatures placed in each wall.

f) Concrete or mortar is shot beginning by filling bores thus forming connectors, next concrete or mortar is shot on one face of the surface, covering existing armature thus forming first wall

g) Next, concrete or mortar is shot on second wall of the surface thus finishing second wall.

[0026] Alternatively, connectors can be prefabricated for this reinforcement application. In this case, the work method is similar, but introduction of connectors' armatures and folding of ends of armatures is substituted by introduction of prefabricated connectors and introduction of tying bars impregnated with adherent resin through bores that the prefabricated connectors have in both bases, overlapping these tying bars with the armatures of the respective wall. Finally concrete or mortar is shot on both faces.

[0027] Thus former construction is embedded in the double wall formed by said reinforcement.

Applications of the structures of the invention

[0028] Industrial application of the herein disclosed double or multiple concrete or mortar walls focuses mostly on building construction and in engineer works. All types of structural elements, surfaces and architectural forms used in constructions and engineer works can be built with same.

[0029] The structures built according to examples of the invention may be foundation slabs, basement walls, load walls, closure walls, separating walls of spaces, pillars, beams, girders, drop forgings, and all types of covers, brackets, vaults, domes, etc.

[0030] Besides the ones previously mentioned, applications in civil engineering works of structures according to the invention may also include: construction of water storage deposits, soil containment walls, caissons for maritime port barriers, abutments, stacks and aqueduct and viaduct bridge boards, gravity dams o vault dams as water reservoirs, revetment of tunnels and galleries and in general, forming of any structure or part of same.

[0031] With the present invention any type of conventional reinforced concrete elements can be built in the field of in shop prefabricated reinforced concrete parts to be carried and placed in engineer works, including self carrying panels, slabs, pillars and stacks, girders, sill plates, etc.. These parts can have any required form or dimension.

SUMMARY

[0051] Thus the present invention provides inventive, novel features as compared to the state of the art. The invention provides structures having stiffness in all directions enabling its use in the construction of any surface no matter the stress it may be subject to. The invention is much more versatile than any preceding one as to state of the art since it can be used to make prefabricated panels as Perrin's but also can be directly used in construction works to build any of their parts. Surfaces might have curvatures as is the case of vaults, cupules or any other paddled surface, wherein separation between walls as well as their thickness can be variable allowing adaptation in any point to the required stress level in the same. A material having low heat conductivity may be selected to construct the support, thus bestowing heat isolation features on the surface constructed according to the invention. Furthermore, structures built applying this invention are much more resistant to stresses provoked by seismic movement than conventional ones.
