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.
(1) Installation of post-embedded parts: For new buildings, the installation of building curtain walls usually begins with the installation of curtain wall installations with the construction of the main structure of the building, but due to the various structures that may occur during the construction of the main structure The reason is that 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 taken after the replacement. The method of installing the embedded parts.
For the building curtain wall of the reconstruction project. Because the building at that time did not have the architectural design curtain wall or the existing curtain wall, but the transformation process changed the style of the original curtain wall, etc., all of which caused the new curtain wall construction 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.
(2) Installation of the keel of the main force structure: Most of the keel of the main structure of the stone curtain wall is made of carbon structural steel. Therefore, considering the convenience of the actual construction and the comparison between the characteristics of the actual steel and the concrete characteristics of the building, the installation of the keel of the main structure of the stone curtain wall can be designed and constructed by bolts. At the same time, it 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 needs to ensure the welding of a horizontal gap and a vertical vertical gap. It is not possible to weld only one gap, and the length of the welding gap must be completely welded. The welding method, at the same time, the weld skin should be cleaned at any time after welding to ensure 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.
(3) Pay attention to fire safety: When the stone curtain wall is welded to the main body of the keel, due to the large amount of on-site welding work, it is often considered that the operation is convenient and the fire safety requirements are neglected. 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 personnel: On-site construction personnel must wear helmets, safety belts, non-slip shoes and other labor protection articles when entering the artificial site, and the helmet must be brought with good belts, and the wind must be blown or the head can be low. In the case of running away, the seat belt must be hung at any time on a scaffold for construction or other fixed components that meet life safety requirements.
For steel pipe scaffolding for construction, the scaffolding board must be fully covered during construction and use. When the conditions are not met, at least ensure that the working surface of the construction is full of scaffolding, but the quality must be qualified without any cracking. Corroded scaffolding is tied tightly.
(5) Safety of construction electricity: When the installation curtain wall is used for installation and installation, it is often the use of the slant-level distribution box equipment for temporary power connection, but when selecting the three-level distribution box, we must pay attention to the selection of the requirements. Safety 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.
(6) Requirements for stone plate installation: Stone plates should be stored on the stone's own shelves and in the package before installation. If the conditions are not met, it can be tilted and placed on the side of the main structural column of the on-site building that does not affect the construction. However, when placed at the bottom of the plate, a wooden pad or other flexible material with a height of about 100 cm must be placed at the bottom of the plate. When paying attention to the glossy 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.
