PC exterior wall panel installation process

1. The main process for installing PC exterior wall panels is as follows: Build two sets of first floors during the preparation stageDo I need to tie steel bars on the PC board?, and set the two groups of first floors according to the upper and lower floorsDo I need to tie steel bars on the PC board?; Pour shear walls and connecting beams between the first floors of the upper and lower floors. At the same time, the embedded parts are positioned and installedDo I need to tie steel bars on the PC board?Buried parts are divided into categories B and CDo I need to tie steel bars on the PC board?, Group B controls the inside and outside of the PC board and the verticality of the board surface, and Group C controls the up and down movement and elevation of the PC board. First fix the position of Group C on the PC board to determine the elevation, and then fix Group B to determine the horizontal activity position.

2. Dry hanging of external wall PC boards is generally carried out according to the following steps: Construction preparation: Determine the PC boardDo I need to tie steel bars on the PC board?Have the specifications, quantity and installation position of, and prepare the connecting parts, sealing materials, etc. required for dry hanging. Check the flatness and verticality of the wall base. If the deviation is large, it needs to be dealt with. Spring line division: Pop the installation position line and division line of the PC board on the wall according to the design drawings to ensure accurate division.

3. Dry hanging of exterior wall PC boards needs to be constructed based on the characteristics of PC boards and the principles of dry hanging process. However, the current public information lacks a standardized dry hanging process for PC boards. The following are general technical points and precautions based on similar material processes: During the construction preparation stage, materials and tools to prepare PC boards must meet the design thickness (usually 12-20mm), size accuracy (error ≤1mm) and strength requirements (flexural strength ≥15MPa), and the surface needs to be antifouling treated.

4. The lifting process of prefabricated PC components is as follows: Transportation and on-site inspection If the PC prefabricated exterior wall panels are placed and transported vertically, the inclination angle should be greater than 80°, and the parts in contact with the vehicle should be padded with soft cloth. Other stairs, balcony boards and other components can be laid flat, and the number of stacked layers shall not exceed four. Corner protection should be provided for PC components during transportation. After the components arrive at the site, check whether there are defects in the appearance quality and check whether the components exceed the allowable deviation range.

Strengthening method of brick formwork bearing cap pc prefabricated slab in basement

The reinforcement of brick formwork bearing caps with PC prefabricated slabs in the basement needs to be combined with structural inspection results, and the overall stability can be improved by adding steel members, local cast-in-place reinforcement or optimizing membrane connections. The specific methods are as follows: Key points for foundation reinforcement The stability of the bearing caps is used as a connection between the pile foundation and the superstructure. The core components of the superstructure directly affect overall safety.

Adding supports: Adding support structures is a common method of prefabricated slab reinforcement. By adding additional support points below the prefabricated slab, bending and stress concentration of the slab can be reduced, thereby improving its load-bearing capacity. The advantage of this method is that the construction is relatively simple and can quickly and effectively improve the stability of the structure. Use of reinforcing materials: Using reinforcing materials such as carbon fiber cloth and steel plates is another effective method of reinforcing prefabricated panels.

Prefab slab support reinforcement: Before filling the pile caps and ground beams, use wooden squares, steel pipes, etc. to support the slab to prevent lateral movement.

Reinforced concrete strengthening method: Add reinforced concrete to the original prefabricated building structure to enhance its bearing capacity and earthquake resistance. Bonded steel plate reinforcement method: A layer of steel plate is pasted on the surface of the original prefabricated building to increase its strength and rigidity. Carbon fiber cloth reinforcement method: Cover the surface of the original prefabricated building with a layer of carbon fiber cloth to enhance its tensile, bending and shear resistance.

There are three methods to strengthen prefabricated slab buildings: under-slab reinforcement, plywood reinforcement, and on-slab reinforcement. For example, if steel sections are arranged along the four corners, the four sides of the support can be changed into eight sides. The purpose is to easily improve the bearing capacity of the board, or it is also possible to arrange steel sections under the board along the longest side.

Installation and trial hoisting of spreader: Screw the eye bolt into the embedded sleeve of the PC board, hang the hook, and pad the lower end with wooden square or rubber mat.
