modern cities are the world of reinforced concrete, and glass curtain walls are also widely used in the exterior wall decoration of high-rise buildings.

Buildings show different colors from different angles, giving people dynamic beauty with the changes of sunlight, moonlight and lighting. How to install the glass curtain wall? What are the precautions when installing the glass curtain wall? Now let's answer it one by one

installation method of glass curtain wall:

1. Instruments and tools such as (laser) theodolite, level gauge and plumb bob should be used to measure the central position of the connection point between the frame material and the main structure layer by layer on the main structure. The allowable deviation of the positions in the three directions of x, y and Z axes is ± 1.0mm。

2. For component curtain walls, such as tempered glass, insulating glass and other glass that cannot be cut on site, the actual size of the glass should be checked in advance. If it is inconsistent with the design size, the central position of the connection point between the frame and the main structure should be adjusted. Or the glass can be customized according to the actual installation position (size) of the frame material

3. Fix the connector according to the center position of the measured connection point to ensure it is firm

4. The installation of unit curtain wall should be carried out from bottom to top. The frame material of element curtain wall should be installed from top to bottom

5. When the frame material of the element curtain wall or the units of the unit curtain wall are connected with the connectors, the whole curtain wall should be checked and corrected, and then the connectors should be firmly welded with the embedded parts of the main structure (including anchoring with expansion bolts)

6. The gap of the unit curtain wall shall be sealed with V-shaped and W-shaped or other rubber strips, and shall be tightly embedded without omission

7. The element curtain wall shall be installed with glass according to the requirements of the design drawings. After the glass is installed in place, it should be fixed with the frame with rubber strips and other embedded materials in a timely manner, and it is not allowed to temporarily fix or open float

8. The rubber strips on each side around the glass should be a single piece of whole material, which are broken at the corners of the glass. The model of the rubber strip should be correct, and the inlay should be flat.

9. The type of sealant applied outside the rubber strip should be correct (acetic acid type organosilicone adhesive is strictly prohibited on the plating surface of the coated glass). It should be dense and uniform, without omission, and the appearance should be flat.

10. The gap between the units of the unit curtain wall, the gap between the frame materials of the element curtain wall The gap between the frame material and the glass, as well as all other gaps, should be left enough according to the requirements of the design drawings

11. The gap between the units of the unit curtain wall and the gap between the glasses of the implicit curtain wall should be installed according to the design requirements and kept uniform

12. After welding of galvanized connectors, the coating shall be removed, and the weld surface of the damaged galvanized surface shall be brushed with two layers of antirust paint. All materials (including Lianyungang structural parts) and structural measures in contact with aluminum alloy profiles shall comply with the design drawings, without contact corrosion, and shall not be in direct contact with cement mortar and other materials

13. The lightning protection and grounding of curtain wall as well as the installation and construction of all structural nodes (including fire-proof nodes) and closing nodes shall be carried out according to the node structure requirements specified in the design drawings

14. The detergent used to clean the curtain wall should be tested, and the aluminum alloy profile plating, glass and sealant strip should have no corrosive effect, and should be washed in time
