Abstract
The invention discloses a socket type bridge expansion joint device which consists of more than two supporting pieces connected in a matched manner, and is characterized in that the supporting pieces consist of female supporting pieces (2) and male supporting pieces (5), wherein the supporting pieces are square steel pipes and are connected in a dynamic fit embedding manner; the bottoms of the female supporting pieces (2) are closed and are connected with anchor ribs fixedly connected with a bridge main structure; the bottoms of the male supporting pieces (5) are rectangular steel plates (3); the other surfaces of the rectangular steel plates (3) are connected with anchor ribs fixedly connected with the bridge main structure; clearances which are 2-6mm in width are reserved between all the side walls of the female supporting pieces (2) and the male supporting pieces (5); the end openings in the upper side surfaces of the opening ends of the female supporting pieces (2) are arc-shaped. The socket type bridge expansion joint device has the characteristics of reasonable and practical structure and durability and can be widely applied between two beam ends of a bridge as well as between each beam end and a bridge abutment.
Description
Technical field
The present invention relates to a kind of bridge expansion joint installation, especially a kind of spigot-and-socket bridge expansion joint installation.
Background technology
Bridge expansion joint installation refers to as meeting bridge deformation requirement, need arrange expansion gap device between two beam-ends and between beam-ends and abutment.Require this expansion gap device can meet bridge be parallel and perpendicular to bridge axes direction free-extension distortion, smooth-going when can ensure that vehicle passes through again, noiseless, also firm with bridge main anatomical connectivity, more to there is the convenience of good waterproof and dustproof and maintenance and inspection.
At present, the normally used expanded joint structure of bridge mostly is docking style and support type structure.The basic structure at docking style shrinkage joint is with material pay the seams such as pitch, plank, loose hemp fiber, rubber, to make it under any state, all be in compressive state, absorbs beam body dilatation with the tension and compression deformation of packing material, ensures that bridge floor driving is smooth-going simultaneously; But the filler of this structure is easily aging, thus there is fracture or come off, causing shrinkage joint disabler.Support type shrinkage joint is as common comb teeth shape steel plate shrinkage joint, and its basic structure is that the comb teeth-shaped support member be connected intersects mutually to inserting, and supports in the front end of tooth; The shrinkage joint cost of this structure is higher, and manufacture processing difficulties, waterproof ability is weak, and cleaning is complicated.
Summary of the invention
The technical problem to be solved in the present invention is the limitation overcoming above-mentioned various technical scheme, provides a kind of rational in infrastructure, practical, with the long-lived spigot-and-socket bridge expansion joint installation of material.
For solving technical problem of the present invention, the technical scheme adopted is: spigot-and-socket bridge expansion joint installation is made up of the support member be connected, particularly,
Described support member is made up of cloudy support member and positive support member, and both are rectangular steel tube, coordinates nested encryptions each other for dynamic;
The bottom of described cloudy support member is closed, and is connected with the dowel be fixedly connected with bridge main structure;
The bottom of described positive support member is rectangular steel plates, and the another side of described rectangular steel plates is connected with the dowel be fixedly connected with bridge main structure.
Further improvement as spigot-and-socket bridge expansion joint installation:
Preferably, the gap of 2 ~ 6mm is equipped with between each sidewall of cloudy support member and positive support member.
Preferably, the port of cloudy support member openend upper side is arc; Be conducive to reducing its adverse effect to vehicle tyre.
Preferably, the dowel that the bottom of cloudy support member is connected with is the dowel be fixedly connected with direction to the car bridge main structure; Be beneficial to the globality strengthening itself and bridge, be beneficial to integral firmness and the stability at shrinkage joint, ensure its service behaviour.
Preferably, the dowel that the another side of rectangular steel plates is connected with is and the dowel going car direction bridge main structure to be fixedly connected with.
Preferably, the support member be made up of cloudy support member and positive support member is more than 2.
Relative to the beneficial effect of prior art be:
1., by the dynamic cooperation nested encryptions between yin, yang support member, both met the free-extension distortion of bridge, in turn ensure that bridge floor was driven a vehicle smooth-going.
2. rational in infrastructure, practical, durable in use with material, and with being connected firmly of bridge main body structure.
3. because yin, yang support member is rectangular steel tube, therefore its supporting capacity is large, long service life, and can realize effective waterproof and drain function.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in further detail.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, being constructed as follows of spigot-and-socket bridge expansion joint installation:
Support member is 3 that are arranged side by side.Every support member is formed by matching the cloudy support member 2 that connects and positive support member 5, and both are rectangular steel tube, coordinate nested encryptions each other, be equipped with the gap of 3 (can be 2 ~ 6) mm between each sidewall of cloudy support member 2 and positive support member 5 for dynamic.The bottom of cloudy support member 2 is closed, and is connected with the dowel 8 be fixedly connected with direction to the car bridge main structure 1; The port of cloudy support member 2 openend upper side is arc.The bottom of sun support member 5 is rectangular steel plates 3, and the another side of this rectangular steel plates 3 is connected with and the dowel 4 going car direction bridge main structure 7 to be fixedly connected with.
When installing and using, in order to reach, the necessary depth displacement in shrinkage joint is installed, should ensure that the deck paving of direction to the car bridge main structure 1 reaches the identical elevation of end face with cloudy support member 2 through the gradual change slope of certain length, go the elevation of the deck paving of car direction bridge main structure 7 identical with the elevation of top surface of positive support member 5.During installation, positive support member 5 is inserted after in cloudy support member 2, be placed into installation site together, and by dowel 8, cloudy support member 2 is fixedly connected with direction to the car bridge main structure 1, the rectangular steel plates 3 of positive support member 5 is fixedly connected with going car direction bridge main structure 7 by dowel 4.After the installation of shrinkage joint, gutter 6 is set below the abutting end of bridge main structure, to ensure the water flowing into expansion gap device to guide in bridge platoon aquaporin.
Obviously, those skilled in the art can carry out various change and modification to spigot-and-socket bridge expansion joint installation of the present invention and not depart from the spirit and scope of the present invention.Like this, if belong within the scope of the claims in the present invention and equivalent technologies thereof to these amendments of the present invention and modification, then the present invention is also intended to comprise these change and modification.
