Composite aluminum panel curtain wall construction

【China Aluminum Network】 Composite aluminum curtain wall project is a high-tech, systematic and comprehensive project. Once the design is confirmed, it must be strictly organized and managed. The construction of compound aluminum curtain wall is generally divided into three stages.
The early stage is the preparation phase:
The main tasks in the preparation stage include technical preparation, construction organization preparation and construction preparation.
Technical preparation: The engineering and technical personnel on the basis of a comprehensive survey of the decoration site, limit the accurate construction site technical data, check and modify the design drawings, and as a basis for the construction of the construction organization program.
Construction organization: preparations are to be carried out by the person in charge on the basis of the preparation of the construction organization design on the basis of decoration, including the design of the general plan, the division of the construction section, the preparation of the construction schedule, and the implementation of the construction organization (including the staffing of the management personnel and technicians and the construction team). Prepare material plans and construction job plans. Construction preparation: construction of on-site temporary facilities such as office buildings, material processing workshops, etc., installation of construction scaffolds, vertical transportation equipment, erection of construction electrical work surfaces (such as floor signs, etc.), installation and design of composite aluminum sheet processing equipment .
The second stage is the construction stage:
The construction of the section composite aluminum curtain wall includes prefabrication and on-site installation of the composite aluminum sheet.
Machining prefabricated panels: According to the construction drawings, the prefabricated panels are prepared and the numbers, specifications and application positions are listed. According to the installation schedule processing production. In order to make rational use of resources, the inventory of prefabricated panels is generally 1.5-2 times the daily installed amount. After the composite aluminum sheet is formed, it is required to be numbered according to the schedule and stored in order.
On-site installation: Site installation is generally divided into four processes.
1. Installation Skeleton Installation Skeleton procedures include wire laying, embedded parts, and skeleton installation.
Put the line - by the engineering and technical personnel in accordance with the drawings using the instrument on-site release line, put the line should be based on the requirements of the drawings to release the horizontal and vertical baseline, and then take the whip line as the benchmark line.
Embedded parts - According to the location and technical requirements of the nodes to install embedded parts, all embedded parts must be positioned accurately, the anchorage does not allow the phenomenon of virtual connection, embedded parts must be made according to the design requirements of anti-rust treatment.
Skeleton installation - Skeleton installation is accurate according to the positioning of the pay line, and its horizontal, vertical spacing and flatness must meet the design requirements. In order for the curtain wall not to be deformed due to construction and climate, the articulated hinge must be constructed in strict accordance with the design requirements. After the installation of the skeleton is completed, it shall be comprehensively checked including the horizontality, verticality, flatness, and spacing dimension of the skeleton to check whether the embedded parts and hinge points are firm and reliable. After passing the test, the construction of the next process can be performed.
2. Install the composite aluminum plate to ensure the accuracy of the installation and improve the work efficiency. After the skeleton is installed, the number should be written in the corresponding position according to the figure, corresponding to the number of the prefabricated aluminum plate; the fixing should be firm and reliable, and the gap between the aluminum plates The dimensions are not allowed to exceed the design requirements, as this is a condition that guarantees that the adhesive will not be destroyed under the allowable shrinkage thermal expansion conditions and is calculated in the design.
3. After filling the gap and cleaning the protective film all or the aluminum sheet of the construction section, first remove the protective wax from the gap, fill in the strip matching the gap size and fill in the structural adhesive, until the structural adhesive is dried. The protective film can be removed and the composite aluminum curtain wall can be fully cleaned.
4. Scaffolding The composite aluminum curtain curtain wall is generally a large block surface. The joints between the scaffolding and the building will affect the installation. Therefore, the construction work is usually done from top to bottom and the work is completed. A scaffolding.
The third stage is the cleaning and maintenance phase:
Because the composite aluminum plate is a metal material, the surface hardness is low, and the surface protective coating is not allowed to wear. During the construction process, great care should be taken to protect the device; collision and recession and wear are not allowed, and the protective film should be later than the process. Only cleared when completed. After the installation is completed, a thorough cleaning work should be carried out. Use a neutral detergent or water to clean it with a soft cloth. Never use strong acids, strong alkalis or solvents to hard scrub, and avoid damaging the surface protective film of the composite aluminum plate.
