China Metallurgical Construction Research Institute (Shanghai) Co., Ltd. has Shanghai Shanghai Building Curtain Wall Testing Certificate, Shanghai Grade A Housing Quality Testing Certificate and Seismic Identification Certificate.
As the outer protective structure of the building, the glass curtain wall not only has good appearance quality, but also has perfect physical properties, so as to better serve the entire building system and create a comfortable and harmonious living environment for people. The physical performance test of the glass curtain wall also verifies the feasibility of the installation process and installation quality while verifying the feasibility of the curtain wall design.
When performing glass curtain wall inspection, the stress state of the test piece assembly and installation should be consistent with the actual situation of the project, and the consistency between the test specimen and the design pattern should be ensured. During the installation of the test piece, if there is any difference in the material type of the component, the installer should be notified immediately to correct the error, so as to avoid leaving hidden troubles for the subsequent inspection work.
Glass curtain wall inspection is divided into laboratory inspection and on-site glass curtain wall reliability testing.
The following problems are encountered when sending inspections to the glass curtain wall laboratory:
1. The problem of airtightness detection of glass curtain wall. The airtight performance of the glass curtain wall is related to the heat preservation and energy saving effect of the curtain wall. The airtightness inspection of the glass curtain wall can find problems in the design and installation process of the curtain wall, and improve the airtightness index of the curtain wall through the solution of the problem to achieve the purpose of heat preservation and energy saving.
2. Common problems in watertightness detection of glass curtain wall. Rainwater leakage is a common form of functional failure during the use of glass curtain walls. Factors causing leakage of rainwater include the presence of gaps or holes in the surface of the test piece, the presence of rainwater, and the presence of pressure differences between the inside and outside of the test piece. The test of the laboratory is convenient for discovering the cause of rainwater leakage in the curtain wall test piece, and then taking measures to adjust the design and construction plan so that the watertight performance test index of the test piece meets the design requirements.
3. Curtain wall wind pressure detection common problems. At present, the wind pressure design of the curtain wall is mostly based on relevant design specifications and calculation software. With the continuous improvement of the relevant specifications of the curtain wall and the gradual maturity of the calculation software, the test piece can generally meet the design requirements when it is tested for wind pressure resistance. There are two points to note during the test.
The scene reliability assessment assessment of the curtain wall includes:
1. Detection of glass curtain wall materials 2. Checking of structural bearing capacity of glass curtain wall 3. Detection of structure and structure of glass curtain wall As a large-scale central enterprise, China Metallurgical Research Institute has Shanghai Shanghai Building Grade Wall Inspection Certificate and Shanghai Grade A Housing Quality inspection certificate and seismic identification certificate. In Shanghai, we have received many cases of glass curtain wall inspection. Under what circumstances do you need to do glass curtain wall inspection? There are mainly the following situations.
(1) Failure to design, construct and accept the glass curtain wall;
(2) Engineering technical materials and quality assurance materials are incomplete;
(3) Before the resumption of construction of the glass curtain wall project;
(4) Damage to the curtain wall after an earthquake, fire, or strong wind;
(5) When the curtain wall glass is broken, the opening part is dropped or the component is damaged;
(6) Quality problems found during the use of glass curtain wall, the owner requested to evaluate the China Metallurgical Research Institute is a professional glass curtain wall inspection agency, in the inspection of all curtain wall inspection business, due to the company's curtain wall inspection technology strength and high quality of inspection personnel All of them are highly recognized by the owners. It is a good choice for you to choose the Glass Curtain Wall Testing Center of China Metallurgical Research Institute.
