Construction platform for foundation pit supporting structure beam-slab column

Abstract

The invention discloses a construction platform for a foundation pit supporting structure beam-slab column. The construction platform comprises an annular operation platform sleeving the outer side ofa concrete-filled steel tube column, the annular operation platform comprises an annular platform panel, a supporting truss located below the platform panel and used for supporting the platform panel, a winch and a water tank which are installed on the supporting truss, and a spraying system located above the platform panel and connected with the water tank through a pipeline. The steel wire ropepenetrates through a through hole in a winding shaft of the winch to be connected with a fixing wheel installed on the steel tube column so as to achieve upward traction of the annular operation platform. The construction platform for the foundation pit supporting structure beam-slab column can meet the requirement for cross construction of foundation pit supporting structure beams, slabs and columns, and is low in manufacturing cost, convenient to use and wide in applicability.

Description

technical field [0001] The invention relates to the technical field of foundation pit construction auxiliary tools, in particular to a construction platform for foundation pit supporting structure beams, plates and columns. Background technique [0002] In densely built cities, the depth of the foundation pit is getting deeper and deeper, and the requirements for the supporting structure are getting higher and higher. More and more foundation pits are supported by reinforced concrete, and the supporting columns are steel columns or steel pipe concrete columns. , when the earthwork excavation operation is carried out after the construction of the upper supporting concrete, and there is a cross-process problem before the lower supporting construction work, the upper supporting beam slab formwork needs to be removed, and the honeycomb pockmarked surface needs to be repaired; due to construction measures or design changes on the steel column If necessary, welding or chiseling is...

Problems solved by technology

[0002] In densely built cities, the depth of the foundation pit is getting deeper and deeper, and the requirements for the supporting structure are getting higher and higher. More and more foundation pits are supported by reinforced concrete, and the supporting columns are steel columns or steel pipe concrete columns. , when the earthwork excavation operation is carried out after the construction of the upper supporting concrete, and there is a cross-process problem before the lower supporting construction work, the upper supporting beam slab formwork needs to be removed, and the honeycomb pockmarked surface needs to be repaired; due to construction measures or design changes on the steel column If necessary, welding or chiseling is carried out on the column or beam slab; the slope of the supporting pile needs to be sprayed with hanging nets, and the general method is dangerous methods such as door-type scaffolding or manual work directly on the gun machine

During the construction of the foundation pit, the ground soil is loosened, the soil is soft, and the strength is insufficient, so the door frame cannot be installed normally; secondly, the door type scaffold has poor stability and is easy to overturn, so it has been banned in some areas; During the operation, the upper formwork, the bonded cushion and the soil will fall directly, which will easily injure the surrounding workers and themselves, and cause a lot of dust at the same time, polluting the environment
