Embodiment Construction

[0030] Please refer to Figure 1 to Figure 7 A cable trough main bearing T-beam composite sidewalk includes a bracket 1, a cable trough 2, a walking board edge beam 3, a walking board 4, and a guardrail round pipe 5. The support 1, the cable trough 2, the side beams 3 of the walking board, the walking board 4, the guardrail round pipe 5, etc. are all made of composite materials. The bracket includes a T-beam connection block 8, a column 9, a corner connector 10, and a beam 11. The lower end of the column is connected to the right end of the beam through a corner connector; The connection block is provided with a through hole through which the bolt can pass, and is used for connecting the pre-embedded metal parts on the T beam through the bolt. The uprights are provided with round holes for the round pipes of the guardrail to pass through. Generally, about three holes are arranged evenly. The cable duct includes a bottom plate 12, a left side plate 13, a right side plate 14, ...

Abstract

The invention discloses a cable trough main bearing T-beam composite material sidewalk and an installation method thereof, comprising a bracket, a cable trough and a pedestrian board integrated block,wherein the bracket is connected with a pre-embedded metal part embedded on the T-beam; the cable trough is placed on the bracket; and the pedestrian board integrated block is laid on the cable trough. The installation method includes the steps: connecting the bracket to the T beam; enabling the guardrail round pipe to directly penetrate into the round hole of the bracket for connection; then connecting the cable trough and the bracket through an expansion screw; and then forming the pedestrian board and the side beam of the pedestrian board into a pedestrian board integrated block, and laying the pedestrian board integrated on the cable trough. As the cable trough is directly arranged on the bracket, and the pedestrian board is directly laid on the cable trough, the cover plate part of the cable trough is saved, and the material cost is saved, and the strength requirement of the pedestrian plate is lower. Therefore, installation is fast and convenient. The cable trough main bearing T-beam composite material sidewalk is composed of composite materials, and has the advantages of corrosion resistance, maintenance-free, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of railway bridge engineering. Background technique [0002] At present, in the construction of simply supported T-beams of high-speed railways in my country, the sidewalk slabs are basically made of C30 concrete, and the brackets are welded with angle steel. On the pre-embedded steel plate inside the slag wall, the columns are welded to the brackets with angle steel, and round steel is interspersed in the middle as railings. These materials currently used are not only heavy, increase the load on the bridge deck, and increase the structural strength requirements of the beam body and bridge piers; they are also inconvenient to transport, difficult to construct, low in construction efficiency, and require a lot of manpower and material resources during construction; Rust requires a lot of manpower and material resources for maintenance; and the production efficiency of these materials is low, and the scrap rat...
