FOUNDATION WALL

Description

[0001] The present invention relates to a building element assembly having isolation properties and anchoring for panel forming the front side of a volume to be filled with concrete to form a foundation wall. Japanese Patent Document JP 2002 030673 A discloses a foundation wall element assembly as described in the preamble to claim 1.

[0002] Building a supporting foundation wall of a building is associated with many requirements and needs. The process is often complex, and a good result frequently depends on the skill and improvisation of the construction workers employed with the task of building the walls and floors.

[0003] Vendors have developed various elements that make the task easier for the builder. Expanded/extruded polystyrene (EPS/XPS) building elements with an outer and an inner wall have been provided which are arranged and filled with concrete at the site. Such products has made the job of building floors and foundation walls, and even walls, easier and less work demanding. Lighter material, better insulation and draining capabilities have increased the deployment of such technologies. However there are problems with such elements related to breakage in transportation, inefficient for reinforcement work, and requirement for concrete post curing work.

[0004] There are however a lot of requirements and needs in the building process that these new technologies solve poorly, and which still must be manually handled by the construction workers, and often in an ad hoc manner.

[0005] Buildings have different requirements to the strength, which means there are many types of building elements as the EPS/XPS elements discussed above having different specifications related to the width of the concrete fillable space. The requirements will for example be different for a wall built of double/triple layered bricks compared to a wall made up of Leca^® blocks. Since there may be multiple needs on a building site, there is a need to provide EPS/XPS elements of different sizes, depending on the requirements of the building. Although an EPS/XPS element is low in weight it is bulky and therefor takes up a lot of space on the building site. It is also a real danger of misusing the EPS /XPS elements causing too thick or too thin walls to be used in the foundation.

[0006] Working with concrete requires extended use of reinforcement, such as complex structures of rods or bars. This is an important element of the durability and strength of the construction. Being able to arrange reinforcements at correct pattern and quantity may be a challenge, and certainly this may represent a critical problem when using EPS/XPS forms or simple construction formwork for filling concrete.

[0007] Foundation walls may be required to be covered by some form of façade plaster, at least on parts being above ground. This can be custom woodwork, or plates that have to be mounted to the foundation wall after construction.

[0008] Using a filled EPS/XPS form requires the construction worker to remove the EPS/XPS in areas of the foundation wall that are to be covered by wall elements or other material.

[0009] Using EPS/XPS forms or simple construction formwork requires the construction worker to be able to remove some, or the entire outer layer of the concrete foundation wall. This must be done after curing of the filled in concrete, which represent a time factor which may delay the construction work. In tight environments this will further add to the complexity of the construction task. The time factor and accessibility to do a proper job are critical parameters in a construction process.

[0010] Many building projects need a concrete wall below the ground surface which forms a solid base for the wall constructions, and which provides predictable isolation characteristics. Isolation underground shall also provide protection against frost expansion in the ground. Today this is made up of individual isolation elements and filling regimes, using gravel, sand and draining at depths that goes deeper than frost conditions during extreme winter conditions. Most of this work depends on the quality of the individual construction worker performing the work, and thus is prone to large variations in quality. A poorly performed job in this field may have serious consequences, leading to damage and costly repairs.

[0011] It is the aim of present invention to provide solutions to one or more of the defined challenges and problems in the building process as described above.

[0012] The present invention provides in one embodiment a device for providing a foundation wall element assembly for construction of a foundation wall wherein the element assembly is mounted in two stages and then provides a variable size room for filling concrete, and thus enables the construction worker to use the same elements regardless of the requirement to the thickness of the underground concrete foundation, and provides an easy access for reinforcement/armoring work.

[0013] The assembly process enables the construction worker to easily arrange the reinforcement while assembling the foundation wall element assembly. The foundation wall element assembly itself comprises an outer wall finishing which eliminates further work on the foundation wall once the concrete to be filled into the foundation wall element assembly has cured.

[0014] It is an aim of the present invention to provide a foundation wall element assembly which is light weight and require a minimum of space when transported, thus reduce transportation resources, and brakeage.

[0015] The present invention may additionally provide a predictable protection against frost expansion close to and under the underground wall.

[0017] The various features described herein are combined in certain ways to describe the embodiments in the figures. It should be understood that the figures are only used as an aid for understanding the invention, and the invention and protection scope also comprise other combinations of the features, as described by the claims.

[0018] The present invention device, foundation wall element, for providing a flexible and easy to mount foundation wall element is now described with reference to the figures.

[0019] In one alternative embodiment of the invention as described in figure 1A it is seen a foundation wall element assembly 100 comprising a foot element 1, and a leg element 2. Foot element 1 and leg element 2 is typically made of a high isolating material such as EPS or XPS. The foot element comprises a first groove 5 for receiving at least a part of the lower part 6 of the leg element 2. The foundation wall element assembly 100 further comprising a panel element 3, wherein the lower part of the panel element 3 is arranged in a second groove 4a, 4b, 4c in the foot element 1. The foot element 1 may comprise more than one second groove 4a, 4b, 4c. When mounted, the panel element 3 and the leg element 2 define a space for filling concrete. The second grooves 4a, 4b, 4c are arranged at a distance from the first groove 5 in the foot element 1 defining alternative positioning of the panel element 3 for adapting to the required concrete filling thickness of the wall when arranged and filled.

[0020] The panel element 3 is of an endurable material such as a fiber cement board having a processed outer surface of desired color and texture, and may also have specific characteristics for example for isolation, water permeability, and other.

[0021] The basic idea is that the foot 1 and leg 2 elements are mounted on site in a first operation whereupon the reinforcement arrangements are installed in required pattern as seen in figure 4A. Having easy access to both inner 13 and outer 12 side of the leg element is vital for this job. Reinforcement bars 44a may easily be pushed through the leg elements at required intervals. Being anchored to the reinforcement on the inside of the leg element enables these bars 44a to form the backbone and support for longitudinal reinforcement steel mesh/bars 45 running along the length of the foundation wall element assembly.

[0022] The panel element 3 is further held in position at the upper end by a holding member 9. The holding member 9, as shown in figure 5C and 5D, may be formed as a strip comprising holes 52a, 52b, 52c in a first end and a hook 53 in the opposite second end. The distance of the holes 52a, 52b, 52c correspond to the distances between the second grooves 4a, 4b, 4c in the foot element 1. A plug 11 is provided for insertion through the hole 52a, 52b, 52c and is inserted in the hole 52a, 52b, 52c corresponding to required concrete filling thickness, and will when pushed into the topside of the leg element 2 fix the holding member relative the leg element 2 and define a known distance to the hook 53. The topside of the holding member 9 may further comprise guiding means 51a, 51b, 51c, such as engraved lines, perforations, or other sign elements. The purpose of the guiding means is to enable the construction worker to exactly position the top of the leg element 2 relative the holding member 9 when inserting the plug 11 through one of the holes 52a, 52b, 52c and into the topside of the leg element 2 . The guiding means 51a, 51b, 51c may indicate the distance to the hook 53, such that when guiding means 51a, 51b, 51c is in line with the inner side of the leg element 2, the distance to the hook 53 is precisely defined. The hook 53 is when arranged to embrace the top side of the panel element 3 defining the maximum distance the topside of the panel element 3 can be moved from the outside 12 of the leg element 2.

[0023] A further optional distance member 10 is illustrated in the figures. The distance member 10 may be provided in different sizes, and will be selected dependent on which second groove 4a, 4b, 4c the panel element 3 is to be mounted in when wall is built. The distance member 10 may comprise a tip 55, a space member 56 and a head 57, and when the tip is pushed into the outside wall of the leg element 2 all the way to the space member 56, the head defines a limiting distance the panel element 3 can be moved towards the leg element 2 when mounted.

[0024] In use, it is practical that the chosen second groove 4a, 4b, 4c to mount the panel element 3 in, the size of the optional distance member 10, and the chosen hole 52a, 52b, 52c to mount the plug 11 in corresponds such that the distance between the outside 12 of the leg element 2 and the inside 14 of the panel element 3 is the same from bottom to top. The room 110 defined by the foot element 1, the leg element 2 and the panel element 3 may when filled with concrete and the concrete is cured be a weight bearing part of a wall.

[0025] When using both the holding member 9 and the distance member 10 to hold the panel element 3, the panel element will be held in a biased tensioned manner, since when the panel element 3 is held in the second groove 4a, 4b, 4c in the bottom part, the distance member push the top part of the panel element 3 outwards away from the leg element 2, and the hook 53 on the holding member 9 will hold the top of the panel element 3 back. Thus the panel element 3 is held in a locking manner at a fixed distance from the leg element 2.

[0026] Depending on the environment the foundation wall element 100 is to be mounted in, a variety of forms in the interlocking section 6, 20, 30, 50 of the foot element 1 and the leg element 2. Figure 1A, 2A and 3A show 3 different forms. Other forms may be chosen.

[0027] In figure 4A - 4D there are illustrated how elements may be arranged to form a wall structure. It is seen that the leg element 2 is inserted in a first groove 20 in the foot element 1. The groove is in this instance of the same width and form as the bottom part of the leg element 2 such that when inserted in the groove 20, a tight fit is achieved. A panel element 3 is inserted into the second groove 4a to establish a minimum width in the lower part of the room 110. At least one distance member is chosen having a length between space member 56 and head 57 corresponding to the second groove 4a distance from the first groove 20, and pushed in to the outside 12 of the leg element 2. The leg element may comprise preformed holes (not shown) in its outside surface 12 for receiving distance members 10. The panel element 3 is then arranged to rest on the head 57 of the distance member, and a holding member 9 is arranged to grip the top end of the panel element 3 by the hook 53, and a plug 11 is inserted in a hole 52a in the holding member 9 and pushed down in the top of the leg element 2. Guide line 51a may be used to align with the inside edge of the top end of the leg element2. Preformed holes (not shown) may be provided in the top end of the leg element 2 for receiving the plug 11. The plug 11, when arranged in hole 52a , and when bottom of panel element 3 is arranged in second groove 4a, will typically ensure that the distance between the inside 14 of the panel element 3 and the outside 12 of the leg element 2 corresponds both in bottom and top. Reinforcement bars /armor 44a1, 44b may be arranged before panel element is mounted.

[0028] When a foundation wall is built it may be necessary to mount several foundation wall element assemblies 100 side by side, or meeting in a corner. A connecting member 40 may be arranged to hold the panel elements together. The connecting member 40 may have various sizes and angles between the holding grooves/recesses 47a, 47b for the panel element 3. In figure 4B illustrating a wall arrangement as seen from above, a holding element 40 is seen mounded to hold two panel elements 3 together on a straight wall section. 4D illustrates a possible design of such connecting members 40 in two versions, where one is for a straight wall connection, and the other is for a 90 ° corner connection. The connecting member may further be provided with an anchoring element 41, which will add the capability of anchoring the panel elements 3 to the concrete when concrete is filled into the room 110 and cure. Without the anchoring element 41, there is a risk for the panel elements 3 to disengage with the concrete column in the room 110 when the concrete cures.

[0029] In figure 4A it is further shown how armoring 44a, 44b is arranged both inside the room 110 and through the leg element 2, and further reinforcement bars 45 are arranged inside the leg element 2. The assembly shown in the figure comprise a foundation wall element assembly 100, and a stack of floor elements 42 arranged on the farther end of the foot element 1 on the inside portion of the foundation wall element assembly 100 such that an inside open space 46 is provided for filling concrete and arranging anchoring to concrete floor. The inside open space 46 may further provide room for holding further reinforcement bars 45. The room 110 defined between the panel element 3 and the leg element 2 may also be provided with reinforcement bars 45 which may use a armoring assembly 44a, 44b for anchoring.

[0030] An additional isolation element 43 may be arranged outside the panel element 3 for further isolation. The longer the foot element 2 extends outside the second groove into which the lower part of the panel element 3 is inserted will provide prevention of heave to build under the wall construction when there is frost in the ground. When the wall has been built as described above, it is possible to fill concrete on the inside of the foundation wall element assembly 100 in the inside open space 46 and above the floor element stack 42 to form the floor of the room inside the foundation wall element assemblies 100, and the room 110 inside the foundation wall element assembly to form the foundation of the wall construction.

[0031] Normally, the foundation wall element assembly 100 will be mounted and filling material 120 will be carefully arranged outside the panel 3, before concrete is filled into the foundation wall element assembly 100 and at the same time concrete for the concrete slab on the inside 13 of the foundation wall element assembly is poured in place. This way there are minimal risk for displacement of foundation wall element assembly elements and reinforcement. It is possible in this way to mount foundation wall element assemblies of high reach, up to more than 1 meter.

[0032] When the concrete has been filled and cured, the foundation wall is completed. There is no need for treating the surface, or remove excessive material from the outside of the foundation wall, such as EPS/XPS above ground level, or formwork. Neither is it necessary to work on the front above ground surface of the foundation wall as this has its intended pretreated surface layer element 3.

[0033] There are no constraints to the size of the foundation wall element assemblies, but one option is that the second grooves 4a, 4b, 4c are provided at an internal distance of 5 cm, and the inner groove 4a is arranged to be 10 cm from the outside 12 wall of the mounted leg member 2, thereby facilitation for wall thicknesses of 10, 15, and 20 cm concrete thickness. A second option is that the second grooves 4a, 4b, 4c are provided at an internal distance of 10 cm, and the inner groove 4a is arranged to be 10 cm from the outside wall of the mounted leg member 2, thereby facilitation for wall thicknesses of 10, 20, and 30 cm concrete thickness. A third option is that the second grooves 4a, 4b, 4c are provided at a variable internal distance of for example 5 cm and10 cm, and the inner groove 4a is arranged to be 10 cm from the outside wall of the mounted leg member 2, thereby facilitation for wall thicknesses of 10, 15, and 25 cm concrete thickness. Other variations may comprise different internal distance between the second grooves 4a, 4b, 4c, and/or the first second groove 4a is arranged at different distances from the outside of the leg element 2 when mounted in the foot element 1.

[0034] Figure 7A show further a simplified embodiment of the foundation wall element assembly 100. In these embodiments the foot 1 and leg 2 element is arranged and fixed either by a ridge and grove arrangement as shown previously, or simply by gluing the bottom surface of the leg 2 element to the upper surface of the foot 1 element such that the two form an L-element. Further, a lower holding member 70 is provided comprising holding means 72 for the panel 3 in one end, and an integrated holding spear 71 in the other end. Alternatively the spear 71 may be replaced for example by an arrangement of comprising holes at intervals for receiving a plug 11 as in the manner described above.

[0035] When using this simplified embodiment the construction worker will simply glue the two leg and foot elements together, and arrange the lower holding member 70. Then the reinforcement 44a, 44b, 45 is put in place, and the panel is arranged in the holding means 72 of the lower holding member 70. A second upper holding member 70 is then arranged at the top of the panel 3, and the upper distance member is fastened to the top of the leg element 2, either by pushing the spear 71 into the top surface of the leg element or by other means such as by pushing in a plug 11. Distance members 10 may be used to ensure minimum distance between the outside 12 of the leg element and the inside of the panel 3 at intervals.

[0036] Using either the more advanced foundation wall element assembly above from figure 1A, or the more simplified version of figure 7a, it is possible to remove the upper holding member 9, 70 when the filled in concrete has cured.

[0037] A further advantage of the present invention is that all the parts of the foundation wall element assembly can be flat-packed for transport and storage. This is a huge advantage, and will minimize the breakage and increase ease of handling.
