Abstract
Bridge expansion joint structure, it includes supporting box, supporting beam, displacement buffer, spring -supported seat, boundary beam, zhong liang, rubber buffer block, anchor muscle. Supporting beam's both ends bottom support in two supporting box through the support respectively, be provided with the displacement buffer between supporting beam's one end and the supporting box, supporting beam top be equipped with and has laid wear -resisting slide layer, the boundary beam of two relative settings place the wear -resisting slide layer that sets up in supporting beam top through the spring -supported seat respectively on, be equipped with well roof beam between two relative boundary beams, boundary beam and well roof beam between connect through the rubber buffer block, the outside of boundary beam be equipped with evenly distributed's anchor muscle. This structure not only can satisfy the bridge horizontal flexible, can satisfy the bridge simultaneously in the deformation of multi -direction emergence, overall structure reasonable in design, and the leakproofness is good, and reducible harm to the road bed has increased the life at expansion joint.
Description
Technical field
The utility model is bridge expansion joint structure, it be arranged at the bridge of road and bridge engineering beam-ends, between beam-ends and abutment, in the articulated position of bridge, for meeting the demand of bridge floor distortion.
Background technology
Bridge expanssion joint refers to the requirement for meeting bridge floor distortion, usually between two beam-ends, between beam-ends and abutment or in the articulated position of bridge, arranges shrinkage joint.Shrinkage joint generally will meet should be able to free-extension in the both direction of parallel, vertical bridge axle, smooth-going without kick, water-tight, solid and reliable when vehicle crosses.
When existing shrinkage joint is installed, in order to drive plan, construction is careless, construction is required not according to erection procedure, insecure, out-of-flatness is installed, leaks, do not meet bridge span structure distortion needs, may occur shrinkage joint after one section uses through often there is out-of-flatness, distort, the steel plate of steel stretching device snaps, warpage and come off and can not normally stretch, coming off, should often stitching interior because there are the foreign material such as long-pending soil, rubbish appears in elastic body stretching device, make its effect of can not bringing into normal play, occur damaging or disabler.
The intact degree at shrinkage joint will directly affect the service quality of bridge construction, the defect at shrinkage joint can further develop to main structure body, and severe patient can cause traffic accident, therefore, choice structure expanded joint structure that is good, function admirable is a very important link in the construction of bridge.
Summary of the invention
The utility model is the bridge expansion joint structure for the beam-ends of bridge, between beam-ends and abutment, in the articulated position of bridge, and its global design is reasonable, effectively can reduce buffering, meet the deformation of bridge in all directions, adds the overall life-span.
The utility model realizes above-mentioned purpose by the following technical solutions:
Bridge expansion joint structure, it comprises support box, supporting traverse, displacement buffering device, spring supporting seat, side bar, central sill, damping rubber block, anchor rib.
Bottom the two ends of described supporting traverse respectively by seat supports in two support boxes, be provided with displacement buffering device between one end of described supporting traverse and support box; Be provided with above described supporting traverse and be equipped with wear-resistant slide plate layer; Two described side bars be oppositely arranged are placed on the wear-resistant slide plate layer that arranges above supporting traverse respectively by spring supporting seat, be provided with central sill, connected between described side bar and central sill by damping rubber block between two relative side bars; The outside of described side bar is provided with equally distributed anchor rib.
Described side bar is C type, and described central sill is I-shaped structure, and described central sill bottom is placed on the top of wear-resistant slide plate layer, and described damping rubber block is buckled between side bar and central sill.
Preferably, described I-shaped central sill is provided with two but is not limited to two, between described side bar and central sill, is all connected by damping rubber block between central sill.
The utility model adopts technique scheme to have following beneficial effect:
This structure not only can meet bridge stretching in transverse direction, can meet the deformation of bridge in multi-direction generation simultaneously, and overall construction design is reasonable, and good airproof performance, can reduce the infringement to roadbed, adds the application life at shrinkage joint.
