What is the code for acceptance of stone curtain wall construction?

1 This section is applicable to the quality acceptance of stone curtain wall engineering with building height not greater than 100m and seismic fortification intensity not greater than 8 degrees.

Leading project

2 The varieties, specifications and performance grades of materials used in stone curtain wall engineering should comply with the design requirements and the 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 aluminum alloy pendant of stone curtain wall should not be less than 4.0mm, and the thickness of stainless steel pendant should not be less than 3.0mm..

Inspection method: observation; Ruler inspection; Check the product certificate, performance test report, material entry acceptance record and reinspection report.

The shape, mullion, color, luster, pattern and decorative pattern of stone curtain wall should meet the design requirements.

Inspection method: observation.

4 The number, depth, position and size of stone holes and grooves should meet the design requirements.

Inspection method: check the entry acceptance record or construction record.

5 The position and quantity of embedded parts and rear embedded parts on the main structure of stone curtain wall and the drawing force of rear embedded parts must meet the design requirements of curtain wall.

Inspection method: check the drawing force test report and the acceptance record of concealed works.

6 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, and the connection between the connector and the stone panel must meet the design requirements, and the installation must be firm.

Inspection method: manual inspection; Check the acceptance records of concealed works.

7 metal frame connectors and anti-corrosion treatment should meet the design requirements.

Curtain wall recruitment network tells the inspection method: check the acceptance record of concealed works.

8 The lightning protection device of stone curtain wall must be reliably connected with the lightning protection device of the main structure.

Inspection method: observation; Check the acceptance records and construction records of concealed works.

9 The setting of fireproof, thermal insulation and moisture-proof materials for stone curtain wall should meet the design requirements, and the filling should be dense, uniform and consistent in thickness.

Inspection method: check the acceptance records of concealed works.

10 The deformation joints and connecting nodes at corners of various structures shall meet the design requirements and technical standards.

Inspection method: Check the acceptance records and construction records of concealed works.

1 1 The treatment of stone surface and slab joints shall meet the design requirements.

Inspection method: observation.

12 glue injection shall be full, dense, continuous, even and free of bubbles, and the width and thickness of plate joint shall meet the design requirements and technical standards.

Inspection method: observation; Ruler inspection; Check the construction records.

13 stone curtain wall should have no leakage.

Inspection method: Water drenching inspection shall be carried out at the leakage-prone parts.
