What Are the Construction Technology of Unit Building Curtain Wall? -WJW Aluminum Supplier Aluminum

Measurement and release are the basis for the construction of the unit curtain wall. The purpose is to ensure the accurate assembly of the building curtain wall of the unit, avoid accumulation of cumulative deviations, and shatter the final grid, resulting in difficulty in the closing gate. The measuring line includes the curtain wall positioning line and the curtain wall high line, the curtain wall positioning line, that is, the approved by the bottom curtain line at the bottom of these curtain walls, and then placed the vertical wire from the bottom to the top on the bottom curtain grid line, and then passing through the latitude and weft instrument The calibration is used to use the steel wire as the curtain wall installation and positioning control line on this surface. The curtain wall standard high line, that is, according to the facade of the building, use the level instrument to draw the horizontal point of the outer eaves of the building, and throw a horizontal line as a horizontal benchmark line. After determining the benchmark line, the benchmark line can be used as horizontal control in horizontal installation. Line. The measuring direction should be noted: the detection and inspection of each grid axis should be coordinated with the measurement data of the main structure, and the errors of the main structure should analyze, determine and eliminate it. " The necessary airlord measures should be arranged according to the actual situation.

Install connection pendant

There are two functions of connecting pendants: on the one hand, the unit glass curtain wall plays an auxiliary support and connection, and strengthens the connection between the curtain wall board and the civil structure. Make the installation of the glass curtain wall smoother. The connection pendant is composed of bolts and connectors. These bolts and connectors are connected and fixed by connecting bolts and embedded components to form a three -dimensional ducting system to form a supporting support system for the unit body. "The three -dimensional micro -adjustment is implemented by the angle code and coding on the unit body. The corners and codes on the unit board can be installed on the connector, which can slide the fine adjustment of the three -dimensional structure of the unit board. "Because the docking connection of the unit curtain wall needs to be completed while installing the unit components in the main structure, the connector of the unit curtain wall should be installed on the main structure. "The connector is connected to the embedded part through stainless steel bolts. Due to the high height of the building, the connector is gradually installed and the structure is matched one by one. The installation accuracy of the connector improves the construction quality of the curtain wall, that is, the good connecter installation accuracy and the structural accuracy of the curtain wall component are effective. ensure.

Unit curtain wall installation

The unit board is lifted, that is, open the electric gourd, slowly lift the plate, and arrange a special person to protect the unit's body from swinging, not touching, lifting, and rising to ensure that the unit's body rises smoothly. The installation layer is equipped with a construction personnel, which is responsible for the positioning and installation of the unit board during the fall. When the unit board falls, pay attention to slow transportation and dispersion. According to the installation location of the board, the installer should pay attention to move the unit board to the correct position, and then fix the bolt.

After hanging, the surface of the unit board should be cleaned and repaired. Among them, the colloid residue and other dirt on the surface (such as the glass surface) can be scraped off with a blade, then washed with a neutral solvent, and finally washed with water; The blade is scraped away, and it can only be cleaned with solvents and water. The curtain wall structure, such as the main components, sealing agents, glass, etc., should be protected to avoid various factors such as structural deformation, pollution, discoloration, and drainage blockage.

Closed water test

According to the construction quality requirements, the curtain wall is cope with the closed water test. The construction of the unit curtain wall is mainly to correctly install the drainage tank at the junction of the two units, and the sealant must be installed at the bottom and side of the installation. During the construction and installation process, the waterproof treatment of each layer must be done well. After the first floor is installed, a closed water test is performed every 5 pieces and every 5 pieces. Put the water in the water tank for at least 15 minutes, and then observe whether there is water leakage. If there is a leak, the oil leakage must be improved, and then the test must be performed until it is qualified. After the test is completed, the drainage holes must be cleaned. All drainage sinks must be cleaned up before installing attachment materials to avoid affecting the normal drainage function after the delivery of the curtain wall.
