Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] In the adjustable bridge support of the present invention, the support includes an expansion deformation body, and the expansion deformation body has a structure capable of injecting curable liquid into the body. Referring to Figure 1, after the support is placed in place, there is a gap between the support and the bottom surface of the beam body, and the bridge support at this point is in a hollow state. Referring to Figure 2, after impregnating or perfusing the expandable deformable body with a curable liquid (such as construction adhesive, expandable epoxy resin, polyurethane, etc.) The seat is in close contact with the beam body and forms a certain pressure to ensure that the support forms a good and reliable support for the bridge beam body, thereby effectively eliminating the void phenomenon of the support. It has the characteristics of si...

Abstract

The invention discloses an adjustable bridge support which comprises an expanding deformation body with the structure which allows the injection of the solidified liquid, and has the advantages of ensuring the support to form a good and reliable support to the bridge beam, eliminating the support disengaging phenomenon efficiently. Meanwhile, the invention is simple in structure, convenient in assembly, and wide in application; the invention can be used singly or can be combined with the various existing bridge beam bearings conveniently, and can be used widely for the support of various newly-built bridge beam bodies or the replacement of the bridge beam support.

Description

technical field [0001] The invention relates to highway and railway bridges, in particular to a bridge bearing whose vertical support height can be adjusted. Background technique [0002] The bridge support is set between the superstructure of the bridge and the abutment. Its functions are as follows: to transmit the concentrated reaction force of the fulcrum of the beam end to the abutment more evenly; to ensure that the bridge span structure can withstand loads or temperature changes. It can well complete the required deformation, namely: the free rotation of the end and the horizontal expansion and contraction of one end; firmly maintain the correct position of the bridge span. [0003] Plate girder bridges and box girder bridges supported at four points are widely used in design. According to the principle that a plane is determined by three points, one of the four-point supports may be empty. If a support (support) rests against the adjacent plate, even the phenomenon...
