Abstract
The utility model discloses a connection element for a concrete expansion joint, which belongs to the technical field of construction engineering. The connection element is characterized in that two symmetrical main panels are fixed by bolts, two side fixed plates forming an acute angle are arranged at the inner sides of the upper edge and lower edge of the main panels, meshes are formed in the side fixed plates, and support vertical plates are fixed at the middle parts of the two symmetrical main panels. The concrete floor expansion joint connection product has high bearing capacity and is capable of providing better protection to construction expansion joint combination in various concrete floors; different from the existing profiled steel sheet technology, the connection element disclosed by the utility model has a high-strength steel triangular cross section, which reinforces the topmost end of an expansion joint, and the highest impact force is absorbed by the topmost end of the expansion joint when various logistics vehicles pass through, so that and a high or continuous traffic flow can be borne and the junction of the expansion joint cannot deform.
Description
Technical field
The utility model belongs to construction engineering technical field.
Background technology
At present, in the time building large area concrete ground, owing to will considering the concrete surface problem of expanding with heat and contract with cold, therefore to be designed with on the ground shrinkage joint, shrinkage joint at first way is, with saw, large-area concrete is sawn into fritter by code requirement, also has mosaic glass bar that concrete surface is separated and does this kind of method of expansion joint and only lean on concrete self intensity to bear external force seam crossing and be easy to breakage.Later stage is used profiled sheet to be mounted in concrete surface and to do expansion joint use, because profiled sheet sharp corner does not have stiffening device under the continuous action of external force, has used between steel plate sharp corner of a specified duration to produce distortion, can not protect well seam and joint.
Summary of the invention
The purpose of this utility model is: a kind of concrete extension joint connector is provided, and it can make shrinkage joint high efficiency, the high-quality of concrete surface obtain construction processing.
The technical solution of the utility model is: two symmetrical main panels are bolted, and on main panel, inner side, lower edge is provided with the side fixed head that is acute angle, on side fixed head, is provided with mesh, is fixed with a riser at two symmetrical main panel middle parts.
The beneficial effects of the utility model are: concrete surface expansion joint product tool has remarkable power of endurance, can be to the construction joint in various concrete surface in conjunction with better protection is provided.Be the triangle cross section of high strength steel with the difference of existing profiled sheet technology; the top termination that it has strengthened seam when various logistics vehicles by time just this position absorbed maximum impact force and shouldered to such an extent that live the larger or magnitude of traffic flow continuously, protect this seam joint not deform.
Brief description of the drawings
Fig. 1 is that the utility model uses structure graph;
Fig. 2 is the utility model top view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in the figure, the 1st, main panel, the 2nd, side fixed head, the 3rd, bolt, the 4th, a riser.
Side fixed head 2 strikes out latticed, side fixed head 2 is combined with concrete better, main panel 1 height is identical with concrete height, and the bar steel plate that actual main panel 1 and side fixed head 2 are integrated is stamping, side fixed head 2 is acute angle layout with main panel 1, also be that side fixed head 2 is combined with concrete better, fix reasonable stress, strengthened the intensity of concrete surface expansion joint, in the time that expansion joint is flexible or when concrete surface carries, can not be damaged.Bolt 3 adopts the engineering plastics softer than metal material, and effect is better, on a riser 4, is provided with open screw, and screw fixes connector entirety on the ground by screw.
