Abstract
The utility model relates to a bridge construction part, in particular to a bridge expansion joint, which is formed by a V-shaped expansion part and a pair of F-shaped steel structures; the pair of F-shaped steel structures are placed in a mirror image mode; a meshing tooth block and a groove are respectively arranged at the upper part of the inner side of each of the pair of F-shaped steel structures from top to bottom; two ends of the V-shaped expansion part are embedded into the two grooves; more than one anchor ribs are arranged at the outside of each of the pair of F-shaped steel structures; an elastic packing block is arranged at the lower position between the pair of F-shaped steel structures. The bridge expansion joint is simple in structure, is convenient to mount during construction and can be directly used on a bridge after batch production, only the dimension needs to be known before the production, the production is convenient, the bridge expansion joint adopts the steel structures, the precision is high, the stability is good, an expansion device between the steel structures is not likely to fall, the use period is long, the later maintenance is convenient, the bridge expansion joint has better elasticity and the maintenance period is prolonged.
Description
Technical field
The utility model relates to a kind of Bridge Construction parts, relates in particular to bridge expanssion joint.
Background technology
At present, the expanded joint structure of bridge mainly adopts the structures such as supporting type and dock.Comparatively the complicated construction difficulty is large for the supporting type Structural Tectonics, and cost is higher, easily is out of shape the maintenance difficulty, and continuity is not high, vehicle through out-of-date have obviously overturn sense; The dock structure is that the mode as filler is placed in to shrinkage joint, and this technique filler is easily aging, thereby ruptures, comes off, and then lose its due function, because the flexible rule of bridge force-bearing is difficult for grasping, make problem more serious again, be unfavorable for maintenance in the future and reparation etc.
Summary of the invention
The utility model is for the problem existed in background technology, and the bridge expanssion joint of a kind of easy care of design.
Bridge expanssion joint of the present utility model, to be formed by V-type extensible member and a pair of F shaped steel, its described a pair of F shaped steel mirror image is placed, described a pair of F shaped steel inside upper part is equipped with engaging tooth piece and groove from top to bottom, inlaying respectively the two ends of V-type extensible member in the inside of two grooves, be equipped with more than one dowel on the outside of described a pair of F shaped steel, the bottom in the middle of a pair of F shaped steel is provided with the elastic filler piece.
Bridge expanssion joint of the present utility model, be provided with gap between the engaging tooth piece on described a pair of F shaped steel.
Bridge expanssion joint of the present utility model, simple in structure, easy for installation during construction, can produce rear direct use in batches on bridge, only need production pre-test required size just can, convenient production, the bus or train route trafficability characteristic is good, the utility model adopts steel work, and the precision high stability is good, between steel work and roadbed, is connected difficult drop-off, life cycle is long, convenient maintenance in the future, have good retractility, extends maintenance cycle.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical structure sectional view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1 and 2 pairs of the utility model bridge expanssion joints of accompanying drawing, elaborate.
Bridge expanssion joint of the present utility model, to be formed by V-type extensible member 1 and a pair of F shaped steel 2, its described a pair of F shaped steel 2 mirror images are placed, described a pair of F shaped steel 2 inside upper part are equipped with engaging tooth piece 3 and groove 4 from top to bottom, inlaying respectively the two ends of V-type extensible member 1 in the inside of two grooves 4, be equipped with more than one dowel 5 on the outside of described a pair of F shaped steel 2, the bottom in the middle of a pair of F shaped steel 2 is provided with elastic filler piece 6; Be provided with gap 7 between engaging tooth piece 3 on described a pair of F shaped steel 2.
When bridge expanssion joint of the present utility model is used, the F shaped steel 2 of a pair of radial symmetric is connected by V-type extensible member 1, elastic filler piece 6 is placed in behind its inside the joint that will be fixed on bridge, and dowel 5 and horizontal bar is affixed.
As known by the technical knowledge, the utility model can be realized by other the embodiment that does not break away from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrate, and is not only.All in the utility model scope or the change be equal in scope of the present utility model all be included in the utility model.
