Static combination system of building construction operation platform and construction method for existing building renovation

Abstract

The invention provides a building construction operation platform statically determinate combination system and an existing building renovation construction method. The statically determinate combination system comprises multiple building construction operating platforms, each building construction operation platform comprises a stand column formed by assembling standard knots, the stand columns are connected with a building or an external attachment structural body arranged outside the building through wall-attached frames, sleeve frames are arranged on the stand columns and can operate along the stand columns, and cantilever platforms are fixedly connected to the sleeve frames. A simple support platform is arranged between the cantilever platforms on every two adjacent building construction operation platforms. The construction method includes the following steps that in the short side direction of the building, one single-stand-column operation platform is arranged; the single-stand-column operation platform comprises a stand column, a sleeve frame operating along the stand column and an operation platform which is fixedly connected to the two sides of the sleeve; the stand column is connected with the building or an outer stand column body arranged on the building through a wall-attached frame; in the long side direction of the building, the building construction operation platform statically determinate combination system is arranged.

Description

technical field [0001] The invention relates to an operation platform for building construction, in particular to a static-definite combined system of a building construction operation platform and a construction method for rebuilding an existing building. Background technique [0002] The building construction is divided into two stages: main body and interior and exterior decoration construction. The facilities for construction personnel to operate in the domestic construction process are relatively backward. Some companies have introduced electric construction lifting platforms from abroad, but they cannot meet the requirements of the main construction stage, and can only be used for building exterior decoration construction, especially the lack of research on group use technology. At present, the methods used in groups are: single column installation and double column installation. Single column installation and use, such as figure 1 As shown, the force-bearing struct...

Problems solved by technology

However, it belongs to the super static structure, and the operation platform is fixed at both ends between the two columns. When the driving mechanism on the two columns rises and falls asynchronously, especially when there is a problem with the driving mechanism on the two columns, the anti-falling safety device operates. It will generate a large additional internal force inside the statically indeterminate structure, and there will be safety hazards

[0003] When the construction operation platform is used in the project, the column needs to be attached to the building to achieve a certain working height, such as image 3 As shown; when the existing building is being renovated, it may not be allowed to attach to the existing building, which limits the application of the building construction operation platform in the existing building renovation project
