Abstract

The invention provides a railway bridge walking plate, an installation structure and an installation method. The railway bridge walking plate is a walking plate made of composite materials and is of a hollow multi-cavity structure, the railway bridge walking plate can be set at any length, the railway bridge walking plates can be installed in a manner of paving two spans or more than two spans longitudinally, the longitudinal walking plates are buckled and pressed by T-shaped section steel, and the T-shaped section steel and installation brackets are welded together. Z-shaped necks are formed in the bottom surfaces of the walking plates and matched with the installation brackets; concave-convex grooves are formed in the sides of the walking plates, and thus the transverse walking plates are inlayed better; an anti-skidding layer of resin and quartz sand mixture is arranged on the surface of the walking plate. Compared with the ordinary concrete walking plate, the defect that the length of the walking plate is not matched with the spacing between the installation brackets is overcome, limitation of single-span installation is also overcome, and thus the problems that the overlapped length of the walking plates is insufficient and thus the walking plates drop due to the great error of the adjacent installation brackets on site, and dropping is caused due to handling faults in the installation process are solved.

Description

technical field

[0001] The invention relates to the field of railway and road bridge construction, in particular to a railway bridge walking board, an installation structure and an installation method. Background technique

[0002] The bridge walking slabs currently used in railway bridges are mainly concrete slabs. Existing concrete walking slabs are widely used on the walking slabs on both sides of railway bridges due to their low price and simple manufacture. However, most of the concrete walking slabs are made on-site, and the appearance size and quality are highly discrete, and they are easy to be damaged. The broken pieces will cause certain safety hazards to the buildings and pedestrians under the bridge; The overlapping length of the walking slab is insufficient, which causes the walking slab to fall off; in addition, the heavy weight of the concrete walking slab is not conducive to the mechanical performance of the installation bracket, which greatly reduces the se...

Embodiment Construction

[0031] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] like figure 1 , 2 Shown, the FRP railway bridge walking plate 1 structure that the present invention proposes is a five-chamber hollow structure, and the cross-sectional size is 528mm * 70mm, and the thickness of the upper and lower panels 4 is 5mm, and the thickness of the vertical plate 5 is 4.5mm. There is a 10mm deep concave groove 2 on the side, and a 10mm thick convex rib 3 on the right side. When installing, the two walking boards can be integrated into one through the conca...
