Steel tube concrete column high-altitude construction safety protection system

Abstract

The invention discloses a steel tube concrete column high-altitude construction safety protection system which comprises a safety operation platform for executing concrete casting work on a steel tube column of the current layer and executing welding work on a steel tube column of the last layer, a safety climbing ladder which is welded on the outer sides of the steel tube columns and is used for making a constructor climb up and down the operation platform, and temporary packways which are fixed on two adjacent steel tube columns and are connected to the two adjacent steel tube columns, wherein the operation platform is a cage body fixedly arranged at an opening above the top of each steel tube column; the cage body can be split off and is separated from the steel tube columns; and a detachable supporting bracket for supporting the cage body are arranged on the top of each layer of steel tube column. By utilizing the technical scheme, the operation platform is mounted and dismounted quickly and easily and can be reused for casting the concrete to the steel tube columns; materials are saved; the operation platform, the safety climbing ladder and the temporary packways form a complete high-altitude construction three-dimensional protection system; the efficiency of steel tube concrete column construction is improved; and the working period is saved.

Description

Technical field [0001] The invention relates to the field of building construction, in particular to a safety protection system for steel pipe column concrete pouring high-altitude construction. Background technique [0002] Concrete-filled steel tube refers to a structural member formed by filling concrete in a steel tube, and the steel tube and its core concrete can bear the external load together. According to different cross-sectional forms, it can be divided into concrete filled steel tube, square and rectangular steel tube concrete and polygonal steel tube concrete, etc. . The basic principle is: Fill steel pipe with concrete. Under the action of force, the concrete has a strong effect on the steel pipe, but at the same time the steel pipe restrains the concrete, so that the concrete in the pipe is in a three-way compression stress state, delaying the occurrence of longitudinal micro-cracks. And development, thereby improving its compressive strength and compressive deform...

Problems solved by technology

The existing method is mainly to build a complete scaffolding frame, and laying scaffolding boards on the scaffolding as a working platform and walking aisle. With this method, the installation is complicated and the disassembly is slow. Every time a layer of construction is completed, another layer of scaffolding needs to be built The construction of the upper layer of the building often delays the construction period, and an overall scaffolding structure is like another building, requiring a large amount of scaffolding materials

In addition, when constructing high-rise buildings, it is difficult for the scaffolding to form a firm and stable structure at high altitudes. If a connection point becomes loose and falls off, the scaffolding may disintegrate and collapse, posing a safety hazard. Therefore, the existing scaffolding system is not suitable for high-altitude steel pipe columns. Construction of pouring concrete
