What are the contents of the glass curtain wall inspection?Then Jingwan professional glass curtain wall manufacturers to tell you.

The glass curtain wall shall be tested as follows:

Mainly includes the anchoring piece drawing force field test report, aluminum type, material mechanical performance test report, aluminum coating thickness impact resistance test report, test report, glass curtain wall glass energy efficiency test report, the compatibility of structural adhesive test report, structural adhesive bonding shaw hardness test report, weather resistance rubber compatibility test report, curtain wall four performance test report.

In addition, other test reports required by the local quality supervision station or the supervision unit of the project construction unit.If the skeleton of the glass curtain wall is steel skeleton, and the welding seam is required to be Grade I and Grade II, it is also necessary to do the welding seam inspection report of the steel structure.

When should the glass curtain wall be inspected?There are mainly the following situations:

1. The design, construction and acceptance of the glass curtain wall are not in accordance with the specifications;

2. Incomplete engineering technical materials and quality assurance materials;

3. Before resuming the construction of glass curtain wall;

4. Curtain wall damage occurs after being hit by earthquake, fire or strong wind;

5. The curtain wall glass is broken, the opening part falls or the components are damaged; 

6. Quality problems were found during the use of the glass curtain wall, and the owner required evaluation. 

The glass curtain wall test is divided into laboratory test and on-site glass curtain wall reliability test.

The following problems will be encountered when the glass curtain wall laboratory is submitted for inspection:

1. Problems of air tightness detection of glass curtain wall

Problems of air tightness detection of glass curtain wall:

Glass curtain wall airtight "airtight" provided by the industry encyclopedia (entry) performance is related to curtain wall insulation (entry "heat preservation") provided by encyclopedia of industry energy saving effect, glass curtain wall air tightness test can be found that the curtain wall design and the problems existing in the installation process, improve air-tightness index of the curtain wall by the solution of the problem, to achieve the purpose of heat preservation and heat insulation.

2. Water tightness test of glass curtain wall

Common problems of water tightness detection of glass curtain wall:

Water leakage is the most common form of functional failure in the use of glass curtain wall.The factors causing rainwater leakage include cracks or holes on the surface of the specimen, the existence of rainwater and the pressure difference between the inside and outside of the specimen.

(2) Laboratory testing is easy to find the cause of rainwater leakage of curtain wall specimens.Then, some measures are taken to adjust the design and construction scheme, so that the test index of the watertight performance of the specimen can meet the design requirements.

(3) Common problems of curtain wall wind pressure detection.At present, the wind pressure resistance design of curtain wall is mostly based on the relevant design code and calculation software.With the continuous improvement of curtain wall specifications and the gradual maturity of calculation software, the test pieces can generally meet the design requirements when tested against wind pressure.

The on-site reliability testing and evaluation contents of curtain wall include:

(1) Testing of glass curtain wall materials;

(2) checking the structural bearing capacity of glass curtain wall;

(3) detection of glass curtain wall structure and construction.
