Abstract

The invention discloses an integral prefabricated cross-laminated timber (CLT) wooden plate girder bridge based on steel side stiffening, which comprises a bridge superstructure and a bridge substructure, wherein the bridge superstructure is spliced from a plurality of CLT wooden girder plates, and the upper part is provided with girder bridge spandrel girders of a girder bridge deck; each CLT wooden girder plate comprises a girder body structure and corner armor steel sides, the girder body structure is glued from at least three layers of wooden veneer sheets, and the corner armor steel sides are buckled on the upper and lower edges on the front and back ends of the girder body structure and used for stiffening the integral body; and the upper and lower edges on the front and back ends of the girder body structure are correspondingly provided with mounting notches of which the structures and dimensions correspond to those of the corner armor steel sides. The invention has the advantages of light weight, environment friendliness, simple structure, reasonable stressing and good compatibility with surrounding environment, is simple to construct, and can solve the problems of poor compatibility with surrounding environment, easy corrosion from moisture and other natural factors, on-site construction difficulty and the like in the existing bridge.

Description

technical field

[0001] The invention belongs to the technical field of bridge construction engineering, in particular to an integral prefabricated CLT plank girder bridge based on steel edge reinforcement. Background technique

[0002] The traditional wood structure bridges mainly use sawn wood, screw laminated wood, etc. The integrity of the structure is poor, it is easy to crack under natural conditions, and the connection failure is obvious under long-term loads, and the traditional wood structure bridges are mostly on-site Construction requires a lot of manpower and material resources, and the construction quality is not easy to guarantee. In addition, because the traditional wooden bridge deck (beam) is directly installed on the abutment or abutment support, moisture can easily penetrate into the wood, causing corrosion at the end of the beam after a long time, eventually leading to the destruction of the entire structure. In the current actual use process, the problem...
