Definitions
- the present invention relates to the technical field of concrete slab formwork systems providing an expansion joint between two adjacent slabs.
- the present invention relates more particularly to an improved expansion joint, particularly in terms of ease of renovation.
- a known formwork system generally comprises an expansion joint having first and second longitudinal members, arranged side by side on the same horizontal plane, and each intended to form an integral part with an upper and horizontal edge of a concrete slab.
- the first longitudinal member is secured to a vertical partition plate for forming the vertical boundary between the two adjacent concrete slabs.
- the first and second longitudinal elements are spaced from each other, each remaining integral with the concrete slab with which it forms an integral part.
- the opening of the expansion joint after retracting the concrete slabs can cause shocks or jolts resulting in deterioration of the concrete and longitudinal elements. said expansion joint.
- a single rather restrictive solution for renovating the joint consists in sawing or breaking the jackhammer concrete in order to permanently remove the longitudinal elements of the expansion joint, and to cast a filling material such as resin or water. concrete in the recess generated by the removal of joints and broken concrete.
- One of the aims of the invention is therefore to remedy these drawbacks by proposing an expansion joint for concrete slab formwork system whose renovation is simplified when degradations of the longitudinal elements of the joint or the concrete in contact with these elements intervened.
- an expansion joint according to the state of the art in that it comprises first and second longitudinal elements, arranged side by side on the same plane horizontal, and intended to form each integral part with an upper and horizontal edge of a concrete slab, preferably with the first longitudinal member secured to a vertical separating means, such as a plate.
- the first and second longitudinal elements comprise arrangements opening at the level of the upper horizontal walls of said first and second longitudinal elements and for removing at least a portion of each of the first and second longitudinal elements for their replacement.
- the second longitudinal element consists of at least two parts fastened to one another by fastening means removable, so that only the removable part is removed and replaced during the renovation.
- the other part remains fixed and anchored in the concrete.
- the first longitudinal element in order to be removed and replaced, is either fixed to the vertical partition plate by removable fixing means, or it also consists of at least two parts fixed one to the other. on the other by removable fastening means, with a removable upper part and a lower part secured to the separating plate.
- the vertical plane defined by the separating plate is offset horizontally with respect to the vertical plane defined between the first and second longitudinal elements.
- the first and second longitudinal elements comprise complementary means for fitting horizontally into one another.
- the horizontal interlock allows a transfer of the vertical loads between the first and second longitudinal elements of the expansion joint.
- the first longitudinal element comprises a stack of three layers of material, with an intermediate layer that is narrower than the other two layers so as to have a U-shaped cross section
- the second longitudinal element comprises a stack of three layers. of complementary material, with an intermediate layer wider than the other two layers so as to form a transverse projection adapted to fit into the hollow of the U-shape of the first longitudinal member.
- the arrangements are in the form of orifices vertically traversing at least the removable portion of each of the first and second longitudinal members, and rods inserted into said orifices with lower ends integral with a fixed part. expansion joint and threaded upper ends adapted to receive clamping members for the removable attachment of said removable portion of each of the first and second longitudinal members.
- the removable portions of the first and second longitudinal members have facing faces comprising complementary sinusoidal profiles to ensure continuity in the separation between two concrete slabs.
- said wheels are always supported by the surface of one of the adjacent slabs. This feature limits the impact and wear of concrete slabs near expansion joints.
- each of the first and second longitudinal elements is made of a polymeric material, or a composite material made from a polymeric material, such as plastic, in particular resin, etc.
- the sanding nature of the longitudinal elements is independent of the removable nature so that it can be envisaged to develop a remarkable expansion joint in that it comprises first and second longitudinal elements made of a polymer material, or in a composite material made from a polymer material, without these having a removable character.
- Figure 1 is a perspective view illustrating an embodiment of the expansion joint according to the invention, before shrinking concrete slabs;
- Figure 2 is a perspective view similar to that of Figure 1, after retraction of the concrete slabs;
- Figure 3 is a cross-sectional representation of the embodiment of the expansion joint shown in Figure 1, before retracting the concrete slabs;
- FIG. 4 is a cross-sectional representation of the embodiment of the expansion joint illustrated in FIG. 2, after shrinkage of the concrete slabs.
- the invention relates to an expansion joint (1) for a concrete slab formwork system that implements at least one vertical separating means, two adjacent concrete slabs, for example a slab, and which is used when it is necessary, for the pouring of concrete, to divide the concrete slab into several parts, depending on its area and its thickness, to create an air space necessary for the absorption of the variations of volumes of a slab, for example under the action of withdrawal.
- the expansion joint (1) comprises first and second longitudinal elements (2, 3), arranged side by side on the same horizontal plane, intended to form each integral part with an upper edge and horizontal of a concrete slab.
- the first longitudinal element (2) is preferably secured to a vertical separating means (4) of the two adjacent slabs, for example a plate.
- the vertical separating means can be directly fixed, for example welded, under the first longitudinal element, or the first longitudinal element (2) can be placed on a vertical separating element already present between the two slabs.
- the first and second longitudinal members (2, 3) can be made of metal, or of a suitable material to be sanded, such as a polymer or a composite material made from a polymer, for example plastic or resin.
- the invention also makes it possible to remedy this problem by the following features, taken alone or in combination with the sanding nature of the longitudinal elements (2, 3), according to which said longitudinal elements (2, 3) comprise arrangements, leading to the horizontal upper walls of said first and second longitudinal members (2, 3), and for removing at least a portion (2a, 3a) of each of the first and second longitudinal members (2, 3) for their replacement.
- the first longitudinal element (2) comprises a stack of three layers of material, including an upper layer (2a), an intermediate layer (2b), and a lower layer (2c).
- the intermediate layer (2b) has a width smaller than that of the upper (2a) and lower (2c) layers so that the first longitudinal member (2) has a U-shaped cross-section.
- the second longitudinal element (3) comprises a stack of three layers of complementary material, including an upper layer (3a), an intermediate layer (3b), and a lower layer (3c) whose width is greater than that of the upper layers ( 3 a) and lower (3 c) so as to form a transverse projection adapted to fit into the hollow of the U-shape of the first longitudinal member (2) and allow the transfer of vertical loads.
- the upper layers (2a) and (3a) may each comprise a surface layer of a polymeric material as mentioned.
- the first and second longitudinal members (2, 3) comprise orifices (5) formed in their thickness so as to pass vertically through all three layers (2a, 2b, 2c, 3a, 3b, 3c). These orifices (5) are adapted to receive as insertion rods (6) fixed at their lower ends to fixed parts of the expansion joint (1).
- the lower ends of the rods (6) are welded to the lower layers (2c, 3c) of the first and second longitudinal members (2, 3).
- the lower ends of the rods (6) can also be fixed to fixed parts of the formwork system on which the expansion joint is mounted without departing from the scope of the invention.
- the upper ends of the rods (6) do not protrude from the first layers (2a, 3a) of the first and second longitudinal members (2, 3), and are, for example, threaded to cooperate with clamping members (7). to lock in position, at least the upper layers (2a, 3a) of the first and second longitudinal members (2, 3).
- clamping members (7) are unscrewed, the upper layers (2a, 3a) of said first and second longitudinal members (2, 3) can be removed and replaced, especially when they are deteriorated or when a vertical shift generating shock and jerk is felt when passing a vehicle.
- the width of the upper layer (2a) of the first longitudinal element (2) is greater than the width of the upper layer (3a) of the second longitudinal element (3), and the lower layer (2c) of the first longitudinal element ( 2) is made integral with the vertical partition plate (4), for example by welding, so that the vertical plane defined by the separating plate (4) is offset horizontally with respect to the vertical plane (P) defined between the first and second longitudinal members (2, 3).
- the longitudinal elements (2, 3) move away from one another but still rest on one of the concrete slabs.
- the stability of the joint is optimal and the appearance of disorders, such as cracks or breaks is reduced.
- the invention therefore describes an expansion joint (1) comprising first and second longitudinal elements (2, 3) each having removable parts, constituted in particular by the upper layers (2a, 3a).
- first and second longitudinal elements (2, 3) each having removable parts, constituted in particular by the upper layers (2a, 3a).
- the intermediate (2b, 3b) and lower (2c, 3c) layers of the first and second longitudinal members (2, 3) may form a one-piece assembly, or the first longitudinal member (2) may be made in one piece. part fixed directly removably, by the same means as above, on the vertical partition plate (4) provided for example with an upper edge at right angles.
- the removable parts of the first and second longitudinal elements (2, 3), in particular the upper layers (2a, 3a), have facing faces comprising complementary sinusoidal profiles.
- the wheels are always supported by the surface of one of the adjacent slabs. This feature limits the impact and wear of concrete slabs near expansion joints.
