Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] figure 1 It is a high-durability fabricated sidewalk system, which includes: sidewalk brackets 1, sidewalk step boards 2 and sidewalk railing posts 3. A sidewalk support 1 and a sidewalk railing column 3 are arranged every 1.5 meters, and a sidewalk step board 2 is laid between every two sidewalk supports 1 . When sidewalk railing column 3 is connected with the end of sidewalk support 1, see Figure 7 , the bottom of sidewalk railing column 3 is inserted in the pit a of sidewalk support 1 end, and its periphery is filled with epoxy mortar 13; In the hole 12 on the sidewalk railing column 3, sidewalk handrail is installed. The sidewalk system is connected by U-shaped bolts 5 of Φ20 embedded in the main structure 4 of the bridge.

[0022] The working principle of the sidewalk system is: the sidewalk step board 2 transmits the vertical load to the sidewalk suppo...

Abstract

An assembled high-durability sidewalk system is composed of hollow footpath slabs, supporting parts which are a triangular plate-rib hollow structure, and the banisters which has a rectangular cross-section and a structural rib at its bottom. Said footpath slabs an supporting parts are made up of active powder concrete. Its advantages are high strength, toughness and durability and low porosity.

Description

technical field [0001] The invention relates to a sidewalk step board and a support structure thereof for bridge engineering. Background technique [0002] The sidewalk system is the main accessory facility of the bridge structure. The existing sidewalk system is composed of sidewalk step boards, sidewalk brackets and sidewalk railing posts. The sidewalk step boards are made of ordinary reinforced concrete, and the sidewalk brackets are steel brackets. Low local impact load capacity, easy to break, heavy maintenance workload and other issues. The heavy weight of existing sidewalk components also increases the burden of the main load-bearing structure. Contents of the invention [0003] In order to overcome the disadvantages of easy cracking and breaking of step slabs of ordinary reinforced concrete sidewalks and poor corrosion resistance and fire resistance of steel supports, the invention provides a highly durable assembled sidewalk system. [0004] The technical solut...
