A type of prefabricated bridge pier suspended platform

Abstract

This utility model discloses a prefabricated bridge pier suspended platform, comprising multiple supports, with at least two supporting angle steels erected on each support. A grid is laid between the two supporting angle steels, and clips are installed on the supporting angle steels to limit and fix the grid. Each clip includes an upper clip plate, a lower clip plate, and fasteners. The lower clip plate is fixed to the bottom of the supporting angle steel, and the upper clip plate is "M"-shaped and can be inserted into the gaps of the grid. The upper clip plate is fixed to the lower clip plate by the fasteners. The suspended platform is assembled to adapt to bridge piers of different shapes and sizes, facilitating quick installation and disassembly, reducing the defects of on-site splicing and welding of traditional suspended platforms, and solving the problems of on-site corrosion prevention and welding difficulties.

Description

Technical Field

[0001] This utility model relates to the field of bridge pier suspended platform technology, specifically to an assembled bridge pier suspended platform. Background Technology

[0002] During bridge construction, to facilitate bridge maintenance and ensure the safety of maintenance personnel, suspended platforms are often installed at the top edge of the piers. These platforms act as a barrier for maintenance personnel, thus ensuring the safety of both personnel and equipment. Due to the different shapes and sizes of piers, the suspended platforms are typically installed using on-site welding of angle steel supports to accommodate these variations. However, the welding process is challenging, time-consuming, and heavily influenced by weather, terrain, and site conditions. This makes it difficult to guarantee welding quality, and post-weld corrosion protection is difficult, requiring frequent maintenance and repairs. Consequently, the service life of the suspended platforms is short, and their safety is compromised. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that the existing technology usually uses on-site welding of angle steel brackets to install suspended piers, which leads to high construction difficulty and long welding period. Therefore, this utility model proposes an assembled pier suspended pier.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A prefabricated bridge pier suspended platform includes multiple supports, at least two supporting angle steels are erected on the supports, a grid is laid between the two supporting angle steels, and buckles that can limit and fix the grid are installed on the supporting angle steels;

[0006] The buckle includes an upper buckle plate, a lower buckle plate, and fasteners. The lower buckle plate is fixed to the bottom of the supporting angle steel. The upper buckle plate is "M" shaped and can be snapped into the holes of the grille. The upper buckle plate is fixed to the lower buckle plate by the fasteners.

[0007] As a further embodiment of this utility model: the end of the lower buckle plate away from the supporting angle steel has teeth protruding upwards, and the teeth rub against and contact the grille.

[0008] As a further embodiment of this utility model: at least two limiting blocks are fixed at the upper end of the bracket to limit the position of the grille.

[0009] As a further embodiment of this utility model, the bracket is also fixed with multiple pressure plates that limit the position of the supporting angle steel.

[0010] As a further embodiment of this utility model: a handrail angle steel is fixed to the end of the bracket, and a railing is fixed to the handrail angle steel.

[0011] The beneficial effects of this utility model are: the suspended platform is assembled by splicing, which can adapt to bridge piers of different shapes and sizes, facilitates quick installation and disassembly, reduces the defects of the original suspended platform on-site splicing and welding, and solves the problems of on-site anti-corrosion and welding construction difficulties.
