The vehicle and the safety of pedestrian passed through on qualitative and bridge.
Due to the problem of such be present, it is therefore necessary to existing bridge expanssion joint is improved.
The content of the invention
The purpose of this utility model is to solve a kind of water proof type bridge expanssion joint of the deficiency of above-mentioned technology and design.
A kind of water proof type bridge expanssion joint designed by the utility model, include two pieces of the left and right beam slab of bridge, at two pieces
Gap between beam slab be present, packed layer is provided with gap, pave-load layer is designed with above every piece of beam slab, is set in described pave-load layer
Bar-mat reinforcement is equipped with, is provided with anchoring piece close to the side in gap in pave-load layer, the anchoring piece is divided into two parts：A part is embedment
The reinforcing bar of pave-load layer, another part are connected with reinforcing bar and are located at the metal portion on beam slab；The top of the metal portion is
Metal decking, the metal decking are fixed in metal portion by multiple rows of screw；Gap is provided between the metal decking of two pieces of left and right；
The medial surface of the metal portion is provided with neck, and waterproof adhesive tape is installed with the neck of left and right two；In the bottom of metal portion close to seam
The side of gap is provided with neutral gear, is provided with removable cover above the gap, the removable cover both ends be located at both sides neutral gear it is interior and
The removable cover may move；The inverted U-shaped bar being supported to waterproof adhesive tape is provided with removable cover.
A kind of water proof type bridge expanssion joint designed by the utility model, its beneficial effect are：All set above beam slab
There is pave-load layer, and bar-mat reinforcement is provided with described pave-load layer, the presence of bar-mat reinforcement not only increases the intensity of pave-load layer, also
Strengthen the ability of the anti-deformation of whole expanded joint structure；In pave-load layer anchoring piece, described anchoring are provided with close to the side in gap
In part part embedment pave-load layer, another part is connected by screw with metal decking, such structure design, is not only facilitated
The dismounting cleaning of metal decking is changed, and also further improves the intensity at whole expansion joint；Also filled between two anchoring pieces
There is waterproof adhesive tape, waterproofing protection can be played a part of in rainfall；Inverted U-shaped bar and removable cover are provided with the lower section of waterproof adhesive tape
Plate, the removable cover both ends are located in the neutral gear of both sides and the removable cover may move, and inverted U-shaped bar and removable cover are deposited
It is unlikely to destroyed enabling waterproof adhesive tape to bear bigger precipitation.
In summary, the water proof type bridge expanssion joint designed by the utility model has higher-strength and convenient dismounting etc.
Feature.
Brief description of the drawings
Fig. 1 is a kind of structural representation of water proof type bridge expanssion joint in embodiment 1；
Fig. 2 is the enlarged diagram at A in embodiment 1；
In figure：Beam slab 1, packed layer 2, pave-load layer 3, bar-mat reinforcement 4, anchoring piece 5, reinforcing bar 6, metal portion 7, metal decking 8, spiral shell
