Embodiment Construction

[0019] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0020] The grid steel bridge deck of the present invention is prefabricated in a factory, and since no pavement layer is required, it can be passed in about 3 hours after being erected on site. In addition, according to different requirements, it can be used for the replacement of bridge decks, and it can also be used to replace the entire bridge in conjunction with longitudinal bridge section steel, which has a wide range of applications.

[0021] It specifically involves:

[0022] 1) grid shape

[0023] The shape of the grid determines the flatness of the bridge deck, which directly affects the driving comfort. The main grid of the present invention is designed as a square grid 4, which is encrypted with diagonal braces. The side length L4 of the square grid 4 is generally designed to be 10cm-20cm.

[0024] 2) Steel rib layout and size

Abstract

The invention relates to a grid steel bridge deck, which is characterized in that the bridge deck consists of grids, wherein the grids comprise transverse ribs, vertical ribs and inclined ribs, the vertical ribs and the transverse ribs are in vertical arrangement for forming square lattices, the inclined ribs are arranged along the diagonal lines of the square lattices, the transverse ribs are provided with notches for passing the vertical ribs, the upper edges and the lower edges of the vertical ribs are provided with grooves clamped with the notches of the transverse ribs, the vertical ribs pass through the notches of the transverse ribs and are rotated to a degree that the vertical ribs are vertical to the horizontal plane for completing the riveting, and finally, the joint seams and the inclined ribs are welded for forming the grids. The upper surfaces of the transverse ribs, the vertical ribs and the inclined ribs are also provided with rectangular tooth openings for increasing the friction force during vehicle passing. The grid steel bridge deck can be prefabricated in factories, and can realize the fast construction completion and the construction period reduction when being applied to the erection and the maintenance of highway bridges.

Description

technical field [0001] The invention belongs to the field of civil engineering highway bridges, and relates to a bridge deck, in particular to a grid steel bridge deck. Background technique [0002] At present, the climax of my country's highway construction has passed, but due to the degradation of materials and the increase of vehicle load, the safety of a large number of old bridges in service is getting worse and worse, and the safety maintenance of bridges is becoming more and more important. But traffic jams during maintenance can lead to greater socio-economic losses. How to quickly restore bridges and restore traffic as early as possible is becoming more and more important. Contents of the invention [0003] The purpose of the present invention is to provide a grid steel bridge deck, which realizes the rapid erection of new bridges and the rapid maintenance of old bridges, greatly eliminates traffic interruption, and at the same time ensures the rigidity and stren...
