Description
Technical field
It the utility model is related to technical field of buildings, more particularly to one kind builds a bridge expansion joint.
Background technology
Building is the general name of building and structures, be people in order to meet social life needs, utilize grasped thing
Matter technological means, and the artificial environment created with certain scientific law, geomantic omen theory and aesthetic principle.Building is with timber structure
Based on building, the traditional architecture in west is based on masonry structure.Modern building is then based on armored concrete.
With simple simple and elegant style, mainly using cogongrass, timber, brick and tile as construction material, using yoke structure as frame mode
(component such as post, beam, a tree, used in making timber for boats, purlin, rafter), actual size, shape and the spacing needed according to structure are combined.This building knot
Structure mode reflects the clear, orderly of ancient times patriarchal society structure and stably.Because the beam column that wooden material makes is not easy to be formed
Huge inner space, ancient architecture just dexterously utilize outport place, form garden.Due to bridge by temperature Change or
Carload acts on, and beams of concrete is produced deformation of expanding with heat and contract with cold, and to ensure the free dilatation of beams of concrete energy, avoids bridge
Yin Wen changes deform and are obstructed and produce stress, cause to destroy bridge structure, are generally located on adjacent two beam-ends or beam and abutment
Deformable device, i.e. expansion joint are set between parados.1st, road-ability is influenceed；2nd, the effect of rainwater and produce Water Damage；
3rd, because the deformation at expansion joint makes the flatness on road surface poor, impulsive force increase of the vehicle to bridge superstructure, reducing bridge makes
Use the life-span.
Utility model content
The purpose of this utility model is to overcome the technical problem of prior art, there is provided one kind builds a bridge expansion joint.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical scheme that：
One kind builds a bridge expansion joint, is included at the top of bridge main beam and fixes downslide plate by anchor respectively,
