Definitions
- the present invention relates to the sector of construction, in particular that of slabs for industrial floors and relates more particularly to a device which is used to equip expansion joints between adjacent slabs.
- Devices for equipping seals with dilation are known in the field of constructions in concrete.
- the effect desired by this kind of device is to form a connection between adjacent slabs, while allowing limited movement of a slab relative to the other in the plane of the slabs, said movement being primarily due to the shrinkage of concrete during taking and then dilation and retraction thermal.
- Devices must perform the transfer loads between adjacent slabs, and maintain the flatness of all the slabs, while avoiding ruptures and deterioration at the edges of the slabs.
- the device must be designed to allow quick and easy installation when pouring concrete slabs. It must also provide resistance sufficient mechanics of the edges of the slabs taxiing and other stresses.
- a first solution known in the state of the technique uses sliding studs that pass through the joint by penetrating the concrete on both sides, and which can be fitted with reinforcements. Those are rather complex systems that are difficult to lay down and to hold in place when pouring the slabs. In in particular, there is a difficulty in maintaining studs parallel to each other for installation on site.
- Another device uses plates of load transfer, which are placed below the joint, so as to extend from one edge of said joint to the other, and which are fitted with anchoring elements. disadvantageously, it's difficult to align individual plates the along a straight joint. In addition, this kind of device does not provide for any reinforcement of the upper part of the joint, called 'joint lips' in technical language.
- the present invention aims to provide a device for fitting an expansion joint between two slabs, which offers a solution for existing problems in state devices technical.
- Figures 1 and 2 show as for illustrating perspective views of two modules like forming a device according to the present invention.
- Figures 3a to 3d show a first sheet cutting, bending and assembly sheet for arrive at a first embodiment of the invention.
- Figures 4a and 4b show details cutting patterns to arrive at two shapes different execution of the invention.
- Figures 5a to 5d show a second sheet cutting, bending and assembly diagram, for arrive at a device according to the invention.
- FIG. 6 shows a cutting diagram, bending and assembly of sheets, of a complete device according to the invention.
- Figure 7 shows yet another diagram of cutting, bending and assembling sheets, to achieve a particular embodiment of the invention.
- Figure 1 shows part of a device according to the invention.
- a complete device extends so repetitive of the constituent parts over a length greater, especially the length of the joint full that is expected.
- the device consists of two similar modules (marks 1 and 2) which are built at from two metal sheets, preferably steel. The sheets are cut according to a predetermined pattern, then folded along a line 3, so as to form parts meshing plates 4 which pass below the median plane 5, from one side of the joint to the other. For laying on the site, the median plane 5 is planned to coincide with that of the joint between the slabs.
- Each module 1 or 2 from of a cut and shaped sheet includes a series of these flat parts 4, which will also be called 'projections' 4 of each module.
- a series of 6 square elements is present, said elements 6 being integral with the projections 4 and comprising a part 7 in the same plane as the projections, and a raised part 8.
- These raised parts 8 are joined together at their ends by a first vertical beam 9 when installed.
- the stringers 9 are intended to strengthen the upper part or edge of slabs, that is to say what will constitute the lips of the seal.
- the raised parts 8 and the side members 9 respectively of the two modules 1 and 2 are back to back, and preferably secured by fixing means temporary, such as 10 bolts, clips or the like adequate means.
- a separation sheet 12 is included between modules 1 and 2, so as to separate the concrete on both sides of the joint.
- the separation sheet 12 can be made of metal or a synthetic material, preferably compressible such as foam polystyrene.
- Anchoring elements having shapes variables, for example studs 11 are preferably attached to the spar 9 of each of the two modules 1 and 2. Such anchors are not necessarily perpendicular to part 8 and other angles can to be chosen.
- each of the projections 4 of each module is connected to part 7 of the neighboring projection, by a second horizontal flat beam 13, when installed.
- this spar 13 does not constitute an element essential. It is purely optional in the context of the invention although it contributes to the rigidity of the assembly because it is under the slab or drowned in this one.
- the length of the projections 4 is such that there is no direct contact between the end 20 of a projection which belongs to a module 1 or 2, and the flat spar 13 of the other module.
- the distance 21 between two adjacent projections of the two modules 1 and 2, such that the distance 22 between a projection 4 of a module 1 or 2 and a flat part 7 of the other module, is such that there is an absence of direct contact between the elements separated by said distances.
- a projection 4 belonging to a module 1 or 2 has no physical contact with any part of the other module, in the assembly of the invention.
- the projections 4 of the device form a gear diagram, with square parts 6 which can be between two consecutive projections.
- the characteristic elements of the invention are as follows: it is a continuous device, can be installed over a significant length of the joint, thus facilitating installation and alignment.
- Said device is generally assembled before being placed on site construction site.
- Said device, while being continuous, comprises parts 4 which are below or embedded in concrete slabs crossing the joint.
- the projections 4 are found on either side of said joint, thus ensuring the charge transfer desired.
- the device includes plus parts 6 at right angles, joined together by longitudinal members 9 which are on both sides of the parts of the joint, and which thus form a reinforcement lips of the joint and secure the assembly.
- Figures 3a to 3d show an example of a diagram for cutting, folding and assembling a sheet 30, to form a module 1 which will be part of the the invention, shown in Figures 1 and 2.
- the sheet 30 is folded at right angles along line 3, such that so that the elements 4 remain in the initial plan.
- the Figure 3c shows the result, seen from above.
- 3d figure shows the assembly of two modules 1 and 2 shaped and cut of the same type to form a device according to the invention.
- Figure 4a clearly demonstrates what we understand in the context of this description like elements 4, 6, 7, 8, 9 and 13 of the form shown in Figures 1 to 3.
- Figure 4b shows a form which is slightly different, and in which the side members 9 consist of a part 9a which extends essentially on the full height of the device, and a part 9b which extends over a reduced height.
- parts 9a of one of the two modules will find opposite parts 9b of the other module.
- the parts 9a of the two modules therefore basically go block the passage of concrete from one side of the joint to the other.
- it can then delete the separation sheet 12.
- it may still be useful to add a separation sheet for example a sheet of polystyrene, which can compensate for significant expansion slabs.
- modules 1 or 2 are represented as comprising four projections 4.
- Modules 1 and 2 include extensions 31 and 32 at their ends, in form of vertical parts which facilitate the mounting of a second device which forms an angle with the first.
- each projection 4 of one of the two modules 1, 2 is located between two parts 7 of the square of the other module.
- This device is equivalent to the devices already described. It includes two types of spars 9: the spars 9a which extend essentially over the height of the device complete, and the side members 9b which extend over a height scaled down.
