Construction requirements and acceptance of hot curved glass curtain wall

First, the construction quality requirements of hot-bent glass curtain wall

1. The hot-bent glass curtain wall and aluminum alloy components should be horizontal and vertical, the elevation should be correct, and mechanical damage (such as scratches, abrasions, indentations) should not be allowed on the surface, nor should there be defects to be treated.

2. All exposed metal parts (pressure plates) of the hot-bent glass curtain wall should be flat in appearance from any angle, and no small deformation, ripples, recess or protrusion of fasteners are allowed.

3. After the corbel iron parts and the T-shaped groove are fixed, they should be welded firmly, and the gap between the concrete contact surface with the main structure should not be greater than lmm, and it should be plugged with galvanized steel plate. The connection between the corbel iron parts and the curtain wall must be cushioned with shockproof rubber pads. The steel weld welded at the construction site should be coated with two anti-rust paints on site.

4. On the metal surface in contact with masonry, plastering or concrete surface, asphalt paint must be painted, and the thickness is greater than 100um.

5. When the hot bending glass is installed, the gap between its edge and the bone must be maintained, so that the gap between the upper, lower, left and right sides is guaranteed. At the same time, to prevent contamination of the glass, especially on the coating side, special attention should be paid to prevent the coating from peeling off and forming a flower face. The installed glass surface should be neat, and there should be no warping and other phenomena. 6. The impaction of the rubber strip and the rubber strip should be dense and comprehensive, and the interface of the two rubber strips must be filled with sealant. When sealing with sealing glue, it should be squeezed full, uniform and consistent, and the appearance should be flat and smooth.

7. The fireproof and thermal insulation mineral wool materials between the layers should be filled tightly and must not be omitted.

Second, the construction acceptance of hot bending glass curtain wall

1. The acceptance of the hot bent glass curtain wall project should be carried out after the completion of the building (excluding secondary decoration), and its surface should be scrubbed clean before acceptance.

2. The following materials should be submitted during the acceptance of the hot bending glass curtain wall project:

(1) Design drawings, documents, design modifications and material substitution documents;

(2) Material and component factory quality certificate, profile test report, structural silicone sealant compatibility and adhesion test report;

(3) Concealed project acceptance documents;

(4) Construction and installation self-inspection records.

3. The quality of curtain wall engineering should be inspected according to perception inspection and sampling inspection. Take one curtain wall as the inspection unit, and each curtain wall should be inspected.

4. The perception inspection of curtain wall engineering should be carried out according to the following eight requirements:

(1) The frame material of the open frame curtain wall should be vertical and horizontal; The glass seams of the curtain wall should be straight and flat, and the width of the joints should be uniform and meet the design requirements.

(2) The variety, specification and color of the glass should be consistent with the design, the color should be basically uniform, and the aluminum alloy material should not have alkali precipitation, mold and coating peeling.

(3) The installation direction of the glass should be correct.

(4) The color of the metal material should be consistent with the design, the color should be basically uniform, and the aluminum alloy material should not have the phenomenon of film removal.

(5) The surface of the aluminum alloy decorative pressure plate should be flat, and there should be no defects such as deformation, fatigue or local crushing that can be detected by the naked eye.

(6) The upper and lower edges and sides of the curtain wall should be sealed, settled joints, expansion joints, anti-vibration joints and the lightning protection system should meet the specifications.

(7) The masking of the hidden nodes of the curtain wall should be neat and beautiful.

(8) The curtain wall shall not leak.
