The initial stage of the building curtain wall is often understood as a decorative component product, but with the increase in the building area of ​​the building product and the height of the building body, many buildings, especially commercial public buildings, are basically adopting buildings. The curtain wall replaces the traditional building structure wall, so the concept of the building curtain wall is not a traditional decorative component, but a real structural force component. Therefore, all materials for the construction of the curtain wall must be treated with safety in order to be taken seriously.
First, the installation of the rear embedded parts: For new buildings, the installation of the building curtain wall usually begins with the installation of the curtain wall installation with the construction of the main structure of the building, but due to various reasons that may occur during the construction of the main structure The utilization rate of the actual construction of the curtain wall embedded parts is about 80%. Therefore, in order to meet the construction requirements of the construction curtain wall, those positions that are not found or have large deviations that cannot meet the installation requirements will be post-buried. The installation method of the piece.

For the building curtain wall of the remodeling project. Since the building at that time did not have an architectural design curtain wall or an existing curtain wall, but the transformation process changed the style of the original curtain wall, etc., all of the new curtain wall construction needs to be set up to supplement the embedded parts to meet the construction requirements of the building curtain wall.
Regardless of the reasons for the post-compensation of the embedded parts, we must pay attention to the installation of the post-embedded parts and the structure of the main structure should not be suspended or installed on the structural surface of the building plaster layer. The installation of the embedded parts cannot meet the safety and stress requirements of the construction.
Second, the main body of the structure of the keel installation: the main structure of the stone curtain wall is the use of carbon structural steel. Therefore, considering the convenience of the actual construction and the comparison between the characteristics of the actual steel and the characteristics of the concrete, the installation of the keel of the main structure of the stone curtain wall can be designed and constructed by means of bolts, and can also be designed and constructed by means of on-site welding. .

When installing the main structure keel of the curtain wall by means of on-site electric welding connection, the following operational points should be noted for the safety of the curtain wall structure and the safety of on-site construction.
The welding between the main structural steel keels requires at least one horizontal gap and one vertical vertical gap. It is not allowed to weld only one gap, and the length of the welding gap must be completely welded. The spot welding is not allowed. The way, at the same time, the weld seam should be cleaned at any time after welding to ensure that the weld is smooth, flat, no slag, no bubbles.
The welding contact surface of the main structural steel keel must be tightly attached, and the welding should not be carried out directly without any gaps, so that the welding gap will have mechanical safety problems.
Third, pay attention to fire safety: When the stone curtain wall is welded by the main body to load the keel, due to the large amount of on-site welding work, it is often only considered to facilitate the operation and neglect the fire safety requirements. Therefore, not only those who require the welding work are required to be certified to work, but also to prepare the electric welding operation to meet the needs of the site. The fine sand and other materials are placed inside the fire-fighting device to prevent spark splashing. At the same time, each person who performs the welding work must have a special person to watch. At the same time, the ground flammable materials are cleaned up. When the steel needs to be cut and processed on site, it is necessary to control the cutting spark splash on the front side of the cutting machine by using a fire-proof device made of otherwise or non-combustible materials.
4. Safety of construction electricity: When the installation curtain wall is used for installation and installation, it is often the use of the spur-level distribution box equipment for temporary power connection, but when selecting the three-level distribution box, we must pay attention to the safety that meets the requirements. The distribution box, do not consider your own convenience to change the structural configuration of the original qualified and safe distribution box, and it is strictly forbidden to use the plug-in power distribution connection device that can be pulled at random on the construction site.
Fifth, the requirements of the stone plate placement: the stone plate should be stored in the stone's own shelves and in the package before the installation. If the conditions are not met, the side of the main structural column of the on-site building that does not affect the construction can be tilted, but a wooden pad or other flexible material with a height of about 2500px must be placed at the bottom of the plate when placed obliquely. In addition, when the stone is placed, pay attention to the smooth surface and the glossy surface. It is strictly forbidden to place the stone plate on the vertical pole of the construction scaffold or on the horizontal pole.
