Protective frame special for construction of building main body

Abstract

The invention discloses building main body construction special prevention scaffold. It is scaffold sealed and around the building outline. It is divided into many units along length direction. Each of the units is used tower crane to lift singly. And it includes frame body and truss. The frame body is single row, formed by steel tube and fastener, and paved with safety net. And its side closed to building is connected to truss. Its features are that the truss and the building have at least two tie points; and the lower-rise tie point can bear the whole frame body dead weight and load. The invention has the advantages of safe, reliable, simple operation, and low cost.

Description

technical field [0001] The invention relates to a building construction scaffold, in particular to a special protective frame used in the construction stage of a building main body. Background technique [0002] At present, especially in our country, it is a trend that the exterior wall decoration materials of high-rise buildings are changed from facing bricks to coatings. Only the use of gondolas can meet the requirements of repeated ups and downs in the construction process of coatings. However, the gondola hangs on the roof of the building and cannot be applied to the construction stage of the main building. Therefore, a special protective frame used in this stage must be used in conjunction with it. [0003] The inventor's application number is 200310110800.0 for the prior invention application, which uses a multi-section planar network frame to protect the construction floor. Although the material is relatively economical, it cannot provide the construction floor with t...

Problems solved by technology

[0005] 1. The fixing point of the protective frame is on the building side beam of the newly constructed floor. In order to meet the construction progress requirements, the formwork of the side beam of this floor must be removed in advance, which will cause inconvenience to the building construction; if it is fixed on the floor, because the thickness of the floor is much smaller than side beams, and the concrete solidification strength is not enough to meet the structural strength requirements

[0006] 2. When fixing on the side beam of the building, because the operator needs to work on the side without protection, the difficulty increases, the safety risk is unavoidable, and the operation is complicated, professional and technical workers must be competent, and the work efficiency is low;

[0007] Due to the above reasons, a professional construction team is required for installation and upgrading, which increases the cost of use
