The curtain wall glass refers to a building envelope structure or a decorative structure in which the support structure system can have a certain displacement capacity with respect to the main structure and does not share the role of the main structure. However, the installation of curtain wall glass is a multi-industry joint construction. It is not only a complex process, but also a very delicate operation. At the same time, it is closely related to the construction schedule of other sub-projects. The following Xiaobian introduces the methods for installing curtain wall glass and the precautions for installing curtain wall glass.
Installation of curtain wall glass method
1. According to the requirements of construction organization design, before installing the sash, it is necessary to check whether the specifications of the sash are in accordance with the design drawings and construction drawings. Take appropriate protection measures during installation to prevent it from falling off.
2. Before the installation, the sash should be cleaned as necessary. When installing, attention should be paid to the clearance between the top and bottom, left and right, front and rear, inside and outside of the sash and window frame to ensure its sealing performance.
3. The specification, type and quality of the sash connector must meet the design requirements. Stainless steel or light metal products should be used. It is forbidden to reduce the number of fasteners such as self-tapping screws, and the bottom hole of the self-tapping screw should be strictly controlled. Diameter size.
4, curtain wall glass inspection is to pay attention! The inspection items of curtain wall glass include: dew point, visible light transmittance, shading coefficient, heat transfer coefficient, impact resistance, debris state, impact properties of shotgun shell.
Installation curtain wall glass construction considerations
1. Review the construction scheme of elliptic glass curtain wall, the summary of the construction technology; review the warranty information of the construction materials, the structural silicone sealant warranty data, together with the contact material compatibility test report, and the insurance life limit information; the auxiliary materials should comply with the national standards. Technical standards and related regulations.
2. Before the construction, carefully review the construction drawings according to the characteristics of the project, paying particular attention to verifying the detailed treatment of the special parts such as settlement joints, corners, windowsills, and parapets, and whether it can meet the requirements of anti-seepage. The focus of supervision is to pay special attention to the construction quality of these sites.
3, inspection of aluminum alloy profiles, glass, assembly, accessories specifications, model, processing and production quality must meet the design requirements, auxiliary materials meet the design requirements and the relevant technical standards, inspection requirements, in order to be used for the project. The metal and glass construction surfaces shall be cleaned with a clean rag covered with toluene, mixed with toluene or methylhydrazine, acetylene, ketones, alcohol, butanone and the like, and the sealant rubber shall be evenly and tightly sealed, and its thickness shall be greater than 3.5. Mm, the ratio of width to thickness is 2:1.
4, check the gauges, gauges, theodolite periodic verification report.
5, layer by layer review of the curtain wall control line and the actual construction of the relevant space, check the quantity and location of embedded parts, operating conditions and scaffolding and other security measures.
6. After the curtain wall frame is completed, the glass must be filled with sealant at all nodes. Do not block the drain hole when installing the curtain wall. Ensure that the waterproof performance of the curtain wall meets the design requirements.
7, curtain wall installation must be reliable and solid, metal accessories in addition to stainless steel, must do anti-corrosion treatment, anti-metal contact corrosion. Welds are fixed, and the welding quality is inspected one by one. The bolts must be secured against looseness. The glass and the frame must be elastically connected. The size of the bottom pad and the number of positions meet the design requirements.
8, curtain wall opening, expansion joints position and width, sealant filling should meet the design requirements, in line with regulatory requirements to ensure the function and safety; horizontal and vertical, beautiful and generous.
9. Construction requirements for lightning protection and grounding for super high-rise glass curtain walls and construction requirements for fire protection and fire-retardant plugging should be emphasized.
10. After the construction is completed, the item-by-item inspection shall be carried out in a timely manner to include the sprayer's water-jet performance test. Acceptance shall be made according to the quality inspection standards and relevant technical standards.
Editor's summary: The method for installing the curtain wall glass and the precautions for installing the curtain wall glass are introduced here. I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
