Description

A high-rise building cantilever component support system

technical field

The invention belongs to the technical field of building structures, and in particular relates to a support system for cantilevered components of high-rise buildings.

Background technique

Scaffolding is a working platform set up to ensure the smooth progress of various construction processes. According to the erection position, it can be divided into external scaffolding and internal scaffolding; according to different materials, it can be divided into wooden scaffolding, bamboo scaffolding and steel pipe scaffolding; according to the structure form, it can be divided into vertical pole scaffolding, bridge scaffolding, portal scaffolding, suspension scaffolding Hanging scaffolding, picking scaffolding, climbing scaffolding.

Different types of engineering construction use scaffolding for different purposes. Most of the bridge supports use bowl buckle scaffolding, and some use portal scaffolding. The main structure construction floor scaffolding mostly uses fastener scaffolding. The vertical distance of the scaffold pole is generally 1.2-1.8m; the horizontal distance is generally 0.9-1.5m.

Compared with general structures, scaffolding has the following characteristics in its working conditions:

1. The load variability is large.

2. The fastener connection node is semi-rigid, and the rigidity of the node is related to the quality of the fastener and the installation quality, and there is a large variation in the performance of the node.

3. There are initial defects in the scaffold structure and components, such as the initial bending and corrosion of the rods, the size error of the erection, and the eccentricity of the load.

4. The connection point with the wall has a large constraint variation on the scaffolding. The research on the above problems lacks systematic accumulation and statistical data, and does not have the conditions for independent probability analysis. Therefore, the value of the structural resistance multiplied by an adjustment factor less than 1 is determined by calibration with the safety factor used in the past.

Floor-mounted scaffolding refers to scaffolding that can be placed on the ground and fixed.

In the field of building design and construction, local cantilevered structures such as cantilevered beams and slabs are often encountered. Since local cantilevered structures such as cantilevered beams and slabs are relatively high from the ground, during construction, if the traditional floor support is used However, there are technical problems such as super high frame construction, high safety risks, and a large amount of turnover materials.

Therefore, designing a support system for cantilevered components of high-rise buildings to reduce the erection height of the support frame, reduce the turnover material occupation of the support frame, and ensure the safe use of the support frame has become a technical problem to be solved urgently by those skilled in the art.
