Overhauling construction platform capable of being quickly installed and detached, and construction method for same

Abstract

The invention discloses an overhauling construction platform capable of being quickly installed and detached and a construction method for the same. The overhauling construction platform comprises a suspension bracket platform system, a hoisting mobile system and an anchoring system, wherein the hoisting mobile system is arranged on a bridge structure body to hoist and move the suspension bracket platform system; triangular truss main beams are fixed under the bridge structure body via the anchoring system; the suspension bracket platform system has a plurality of triangular truss main beams mounted under the bridge structure body and longitudinally distributed along the bridge structure body, a plurality of secondary beams fixed on two adjacent triangular truss main beams at intervals to form a stress skeleton for the platform system, and a panel placed and fixed on the secondary beams to form the platform. The overhauling construction platform capable of being quickly installed and detached is economically suitable and safe in structure; bridge strengthening effect and quality can be guaranteed; construction safety can be ensured; and construction work efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of bridge engineering. More specifically, the present invention relates to a maintenance construction platform that can be quickly installed and dismantled. Background technique [0002] Periodic maintenance and reinforcement of bridges has become a new hot spot in bridge engineering construction. As one of the important work platforms of bridge reinforcement engineering, the maintenance construction platform is increasingly favored by engineers and technicians for its structural form, applicability, safety and economy. Pay attention to. In the bridge maintenance and reinforcement construction, according to different bridge profiles, the existing maintenance construction platforms include steel pipe scaffolding at the bottom of the beam, bridge inspection vehicles, fixed maintenance platforms, construction hangers and other forms. [0003] Steel pipe scaffolding at the bottom of the beam has high requireme...

AI Technical Summary

Problems solved by technology

[0003] Steel pipe scaffolding at the bottom of the beam has high requirements on the bearing capacity of the foundation, high labor intensity for workers, high support costs, and a long construction period. It is only suitable for land bridges with very small clearance under the bridge

[0004] The bridge inspection vehicle is flexible and convenient to use, but the cost is very high, and due to the load limit of the bridge inspection vehicle, the number of construction personnel is limited, and it cannot adapt to large materials and equipment. It is only suitable for minor repairs and repairs, and some sidewalks are wider or webs Higher bridges cannot be used

[0005] The fixed maintenance platform is more convenient to use, but it is also limited by the load and the number of construction personnel. It cannot adapt to large-scale materials and equipment. It is only suitable for minor repairs and repairs. From the current situation, generally only super-large bridges are equipped with fixed maintenance. platform

[0006] The construction hanger is the main form of the construction platform for bridge maintenance at present, but the existing construction hangers have the disadvantages of heavy hanger structure, high cost due to the inability to turn over the use, insufficient stability of the construction platform or long construction period
