The technical field to which the invention relates.

The present invention relates to a precast system for performing expansion joints, as defined in the preamble of the independent claim 1.

The invention relates to the molding of concrete floor slabs, in particular to the molding of the edges of the plates, or ribs, as well as to ensure the protection of these edges and improved means for transferring loads between adjacent plates.

It is well known that slabs of concrete floors are cast inside a mold, usually made of wood or steel. The form provides the edges and defines the space where the concrete will be poured, some of which are removed after the concrete has shrunk, and some are designed to remain in place for the entire life of the floor.

After casting, concrete slabs shrink during curing, causing the edges of the plates to diverge, with the top edge, or edge, of each individual slab being damaged by loads, such as trucks or loaders passing through the joint.

Individual slabs often assume high loads transferred from one slab to another, and therefore a method is required to transfer loads between adjacent slabs in order to prevent the destruction of the seam between adjacent slabs caused by the stresses created by such loads. Usually round, rectangular or lamellar butt pins and plates are placed in concrete so that they protrude at an angle of 90 ° from edge to edge of the formed seam and join the plates together in order to transfer the load through the seam from one plate to another.

The most affordable prefabricated tools for making seams are fixed in concrete slabs by means of a multitude of shear pins that have been welded on each side of the upper slats along their length; however, there is a potential risk of subsequent destruction of these welded pins at the welding site, which can pose serious problems if the pins collapse after the completion of the plate casting, since re-welding on the spot is an extremely difficult task.

Many existing manufacturers of prefabricated seams also produce butt pins and overlays of their own particular design and often produce their butt means so that they can only be fitted with butt pins of their own or similar design, while other standard butt pins may not fit the hole provided in the separation plate.

Purpose of the invention

Thus, the aim of the present invention is to provide an improved precast system for performing expansion joints, which provides maximum protection for the freshly completed weld edge in two planes, and not just in one.

Summary of Invention

An assembly system for carrying out the expansion joints according to the present invention is characterized by the features disclosed in the independent claim 1 of the claims.

Preferred embodiments of an assembly system for performing expansion joints are disclosed in the dependent claims.

According to one embodiment of the assembly system for performing expansion joints, height adjustment is carried out by a special lifting device that is attached to the assembly system for performing expansion joints by means of a threaded sleeve on a lifting lever that passes through a pre-punched hole in the hems, and fixed there by nuts on the other hand; The specified lifting device is subject to a separate patent.

In one aspect, the present invention provides an assembly system for performing expansion joints for forming an edge of a concrete slab, the system comprising a separator plate that can be reinforced by a plurality of convex ribs that can be of any suitable shape and design. The specified separation plate can be made with many holes, which can be of any shape or design required to pass the butt pins of the most known types and sizes, providing the possibility of using a wide range of load transfer mechanisms. Butt pins and docking plates that can be used in this system are the subject of a separate patent.

The separation plate, due to the fact that it can be fixed by clamping between the two upper edge strips, during operation can provide some degree of height adjustment in order to adapt to the different thickness of the plates. Said separation plate is preferably made of sheet metal, but other materials can be used; at the same time the separation plate will remain in place between the slabs of the concrete floor, which are cast on each side of it.

The upper edge strips of adjacent slabs of the concrete floor are preferably fastened to each other by means of compliant fasteners, while as the plates shrink during the curing of the concrete, the upper edge strips of the adjacent plates move apart and the fasteners destroy - 1 029728

Xia, providing the possibility of such movement. Elongated fasteners may include low tensile bolts, studs or rivets, such as nylon or similar plastics, that will be cut or split by shrinking forces. The fastening elements for the upper edge strips are preferably located in the first through holes made in the upper edge strips with exact match and adhesion to the fastening elements to ensure an accurate mutual arrangement of the adjacent upper edge strips.

When the upper rims fasten back-to-back with each other, a curvilinear recess appears due to the possible radii that are formed when the corners are made. Such a recess may accumulate clogging particles and may cause jolts or jolts of a vehicle moving through the seam. This potential problem can be eliminated by applying an extruded profile made of nylon or similar plastic, whose cross section has a shape that exactly matches the curvilinear groove. Such an extruded profile may also contain an appropriate edge or tongue in the lower part of the section, which can be captured and clamped in the correct position by the upper edge strips.
