Detachable reinforcement cage installation platform

Abstract

The invention discloses an assembling and disassembling type steel reinforcement cage installing platform which comprises at least one first subsidiary platform and at least one second subsidiary platform to form the installing platform surrounding a steel reinforcement cage in the circumferential direction. The first subsidiary platforms and the second subsidiary platforms are connected through safety pin structures. Each first subsidiary platform comprises a base and a steel reinforcement cage supporting assembly which is arranged on the base and faces the center position of the installing platform. Each second subsidiary platform comprises a base and a steel reinforcement cage supporting assembly which is arranged on the base and faces the center position of the installing platform. The assembling and disassembling type steel reinforcement cage installing platform is high in rigidity, good in stress and not prone to deformation, effectively improves the mechanization and automation level of construction and improves an operation environment of construction, so that the steel reinforcement cage is safe, convenient and accurate to install and operate.

Description

technical field [0001] The invention relates to a road and bridge construction technology, in particular to an assembled and disassembled reinforcement cage installation platform. Background technique [0002] Bridge engineering is widely used in highway engineering and railway engineering because of its advantages such as small footprint, small settlement, multiple structural forms, and wide application range. Pile foundations are the most common and widely used foundation form in bridge engineering. For some pile foundations with larger diameters and longer pile lengths, the weight of the reinforcement cage is relatively heavy and the spacing between the main reinforcements is relatively dense. than very difficult. [0003] In the prior art, the super-long and super-heavy reinforcement cages are installed in the following ways: [0004] refer to figure 1 with figure 2 One way is to suspend and install the reinforcement cage by crossing the section steel pole beam. Th...

Problems solved by technology

However, for heavy reinforcement cages, the operation safety is not high and it is not conducive to the development and progress of construction technology

[0006] The above two methods require manual operation to pass through the steel cage, so the degree of mechanization and automation is low, the work efficiency is low, and the risk of construction safety is high.

Especially when the design weight of the pile foundation reinforcement cage is large and the reinforcement spacing is small, it is difficult to install the reinforcement cage using the above two methods

If the steel bar is not damaged and the smaller section steel is used, it needs to be strengthened, and the steel cage can be installed after the force is satisfied, but the operation is still relatively difficult, and there is a high construction safety risk
