Problems solved by technology

For the glass industry and the construction industry, the annual cost of building curtain wall glass is as high as hundreds of millions of yuan. It is obviously a major loss to replace all the expired curtain wall glass, but if no safety inspection is performed, every time a disaster occurs, the loss cannot be measured by data

Embodiment

[0052] Example: Laboratory simulation of safety testing of point-supported glass curtain wall structures 1:

[0053] 1) Preparation of glass samples: In this test, a 3.3m×3.9m point-supported glass curtain wall model is used, which consists of 9 pieces of glass. The material information used in the model is as follows: 4 steel profile columns (Q235 steel, the size is 120mm*80mm*5mm), 4 4-claw type connecting claws, 8 two-claw type connecting claws (90 degrees), 1 single claw There are 4 type connecting claws (long single), and the glass adopts six pieces of laminated glass 8+1.14PVB+8 (including two glass panels with a size of 1.1m*1.5m and four pieces of glass panels with a size of 1.1m*1.2m), hollow Three pieces of glass 8mm+16mm+8mm (including one glass panel with a size of 1.1m*1.5m and two glass panels with a size of 1.1m*1.2m), the gap between the glass panels is 12mm, and the overall sample form is as follows image 3 shown. The structure is constructed according to t...

Abstract

The invention discloses a method for detecting the firmness degree of a connection claw of a supported glass curtain wall, which comprises the following steps of: performing a simulation experiment on a laboratory curtain wall model, selecting a glass plate to be detected, fastening four points of the glass plate, measuring the firmness coefficient DF of the connection claw of the glass plate in a completely fastened state, taking the firmness coefficient DF as a reference, then changing the supporting condition of the glass plate, and repeatedly measuring to obtain the firmness degree of the connection claw of the supported glass curtain wall. And obtaining a corresponding relationship between the glass panel support loosening degree and the DF. According to the method for detecting the firmness degree of the connecting claw of the point-supported glass curtain wall, a convenient, simple and efficient nondestructive testing method can be provided for a point-supported glass curtain wall structure, and safe and reliable use of the point-supported glass curtain wall in the service process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of detecting the firmness of connecting claws of glass curtain walls, in particular to a method for detecting the firmness of connecting claws of point-supported glass curtain walls. Background technique [0002] Glass curtain wall is a kind of building envelope structure or decorative structure. Its biggest feature is that it successfully organically combines architectural aesthetics, architectural functions, architectural energy-saving and architectural structure, and has become an important part of the urban landscape. Magnificent and gorgeous glass curtain wall buildings are built in major cities in the world, such as the World Trade Center in New York, the Petroleum Building in Chicago, and the Sears Tower all use glass curtain walls. Bank of China Building in Hong Kong, Great Wall Hotel in Beijing and Lianyi Building in Shanghai have also adopted it one after another. So far, a large number of glass c...
