What are the acceptance specifications of aluminum curtain wall projects | JINGWAN

Aluminum curtain wall is widely used nowadays, which has good physical and chemical properties.It perfectly combines the innovative technology of aluminum sheet glass curtain wall with the integration of aesthetics and engineering.The quality acceptance of aluminum curtain wall is related to the effect of building appearance. As the most direct expression of building exterior decoration, the acceptance standard is the key, and it is necessary to check whether the installation process meets the relevant standards stipulated by the state.


I. Acceptance Specifications for Aluminum curtain wall Project:

1. Construction drawing, structural calculation book, design description and other design documents of aluminum curtain wall project.The confirmation document of the curtain wall engineering design by the architectural design unit.

2. Certificate of identification of silicone structure adhesive used in aluminum curtain wall project and certificate of qualification through random inspection;The inspection certificate for the import of silicone structural adhesives;Issued by the state-designated testing institution.The test report on the compatibility and peeling adhesion of ketone structure adhesives;Test Report on pollution resistance of sealant for stone materials.

3. Product qualification certificates, performance test reports, acceptance records and reinspection reports of all kinds of materials, hardware accessories, components and components used in aluminum curtain wall project.

4. On-site drawing strength test report of the rear embedment.

5. Record of the processing and production of curtain wall components and components;Curtain wall installation and construction record.

6. Concealed work acceptance record.

7. Lightning protection device test record.

Ii. Aluminum curtain wall Engineering:

1. Peeling strength of aluminum-plastic composite board.

2. Bending degree of aluminum plate;The freezing-thawing resistance of stone in cold areas;Radioactivity of indoor granite.
