Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] Such as figure 1 , 2 As shown, the present invention discloses a corrugated arch sandwich composite bridge deck, including a corrugated arch rib plate 2, a sandwich material body 3, a composite material upper panel 4 and a composite material lower panel 1; wherein the corrugated arch rib plate 2 The upper position is filled with the sandwich material body 3 to form a combined sandwich layer. Concave joints 22 are evenly distributed on each connecting plate of the corrugated arch rib 2, and convex joints are arranged on the corresponding positions of the lower panel 1. The bottom of the corrugated arch rib 2 and the lower The panel 1 is connected with the adhesive in the form of "convex and concave interlocking". The cylindrical bolt holes are processed at the equidistant distance from the corrugated arch rib plate 2, and the circular frustum bol...

Abstract

The invention belongs to the field of new materials, new structures and combined structures in civil engineering, and particularly relates to a corrugated arch sandwiched core composite material combined bridge deck. The corrugated arch sandwiched core composite material combined bridge deck comprises a corrugated arch rib plate, a sandwiched core material body, a composite material upper panel and a composite material lower panel, wherein the corrugated arch rib plate is connected with the lower panel in a concave-convex embedding mode through an adhesive, the upper portion of the back of the arch is filled with the sandwiched core material body to form a combined sandwiched core layer, and the sandwiched core layer is connected with the upper panel through bolts and an adhesive. Compared with an existing composite material bridge deck, the local wheel pressure resistance and shearing properties of the bridge deck are improved, and the problems that panels directly bearing wheel pressure deform excessively, and a web is prone to bend locally are solved; meanwhile, inclined shearing cracks inside a core board are effectively restrained from expanding.

Description

technical field [0001] The invention belongs to the field of new materials, new structures and combined structures in civil engineering, in particular to a corrugated arch sandwich composite material combined bridge deck. Background technique [0002] Emergency bridges are temporary bridge passages that are quickly erected on rivers, swamps, ditches and other obstacles in emergency situations such as natural disasters or wartimes to ensure the rapid passage of machinery, personnel and vehicles, and play an important role in disaster relief and emergency support. role. As a branch of the bridge, in addition to meeting the general characteristics of the bridge, the emergency bridge also needs to have the following characteristics: (1) The overall structure or components are light and convenient for transportation; (2) Easy to assemble and fast to erect; (3) Easy to disassemble , can be reused. In order to ensure long-distance unimpeded transportation in emergency or abnormal...
