Stone curtain wall is composed of steel structure, glass ribs, etc., and its installation method is dry hanging, but dry hanging has a higher cost for wet paste, but it has certain benefits, because the dry hanging method is safer, more reliable, and not easy to fall.
Therefore, generally relatively high walls are used dry hanging; External wall wet paste is easy to appear caustic phenomenon, affecting the appearance of curtain wall; And the freeze-thaw resistance of wet paste is also relatively broken, if it is in the frozen area, it is easy to cause problems.
Stone curtain wall need to do what tests
1, chemical anchor: generally test the pulling difficulty of the product.
2, steel: mainly test its physical properties, such as tensile and flexural resistance.
3, stone: mainly look at bending strength and water absorption.
4, sealant: mainly to see whether the anti-pollution of the product meets the regulations.
5, but also to detect air tightness, water tightness and wind pressure resistance.
Stone curtain wall quality inspection method
Stone curtain wall is usually composed of stone panels and supporting structures (beam columns, steel structures, connectors, etc.), and does not bear the load and function of the main structure of the building envelope.
Stone curtain wall to be tested are:
1. The varieties, specifications, performance and grades used in stone curtain wall projects should meet the design requirements and the provisions of current national product standards and engineering technical specifications. The bending strength of stone should not be less than 8.0Mpa; Water absorption should be less than 0.8%. The thickness of the aluminum alloy pendant of the stone curtain wall should not be less than 4.0mm, and the thickness of the stainless steel pendant should not be less than 3.0mm.
Test method: Scale inspection; Check product qualification certificate, performance test report, material entry acceptance record and reinspection report.
2. The shape, facade division, color, gloss, pattern and pattern of the stone curtain wall should meet the design requirements.
Test method: observation.
3. The number, depth, position and size of stone holes and slots should meet the design requirements.
Inspection method: Check the acceptance records or construction records.
4. The location, quantity and pulling force of the embedded parts and post-embedded parts on the main structure of the stone curtain wall must meet the design requirements.
Inspection method: Check the test report of drawing force and the acceptance record of concealed works.
5. The connection between the metal frame column of the stone curtain wall and the embedded parts of the main structure, the connection between the column and the beam, the connection between the connector and the metal frame, the connection between the connector and the stone panel must meet the design requirements, and the installation must be firm.
Inspection method: hand test, check the acceptance record of concealed works
6. The anti-corrosion treatment of metal frames and connectors should meet the design requirements.
Inspection method: Check the acceptance records of concealed works.
7. The lightning protection device of the stone curtain wall must be reliably connected with the lightning protection device of the main structure.
Inspection method: Observe and check the acceptance records and construction records of concealed works.
8. Stone curtain wall fire, insulation, moisture-proof material Settings should meet the design requirements, filling should be dense, uniform, consistent thickness.
Inspection method: Check the acceptance records of concealed works.
9. The joints of various structural deformation joints and corners should meet the design requirements and technical standards.
Inspection method: Check the acceptance records and construction records of concealed works.
10. The treatment of stone surface and plate seam should meet the design requirements.
Test method: observation.
11. The plate seam of the stone curtain wall should be full, dense, continuous, uniform, no bubbles, and the width and thickness of the plate seam should meet the design requirements and technical standards.
Test method: observation; Scale inspection; Check construction records.
12. Stone curtain wall should have no leakage.
Inspection method: Water inspection is carried out in the easily leaking part.
