The traditional construction methods of exterior wall insulation include through wall screws and wood checkers. The through wall screw holes are opened on the insulating plate, which is easy to damage the aluminum coil and need to be blocked later, which greatly increases the construction cost; The reinforcement construction is carried out through the combination of screws, wood squares and back corrugations. The construction process is tedious. A cement support rod is placed in the middle of the wall to ensure the cross-sectional dimension of the wall. The more difficult the construction is, the more difficult it is to ensure the quality.
In winter, the external wall insulation device generally includes the external wall formwork, the insulation board on one side of the external wall formwork and multiple fastening devices. The external wall formwork comprises a formwork main body, which is parallel to the insulation board and extends from the formwork main body to the direction away from the insulation board, and a plurality of side panels. However, there are defects in the use of external wall insulation board. Firstly, the connection between insulation boards is not tight, and secondly, the external insulation board is not easy to replace. In order to solve this problem, the insulation method of combining aluminum coil and external wall insulation board is adopted.
The construction structure of the combination of aluminum coil and external wall insulation board mainly includes insulation board, reinforced concrete cast-in-place structure, aluminum mold inner wall board, square tube clamp, square tube back, and one-time pull sheet. The inner side and outer side of the reinforced concrete cast-in-place structure are respectively provided with aluminum formwork inner wall plate and insulation board, and the outer side of the insulation board is also provided with a steel frame for fixing the insulation board.
Fix the plate on the steel frame, and connect the two ends of the disposable pull sheet with the square pipe clamp, so that when the square pipe clamp is pulled mutually, the aluminum coil and the inner wall panel of the aluminum mold are locked on both sides of the reinforced concrete cast-in-place structure. A vertical floor formwork is set above the inner wall panel of the aluminum mold, and the floor formwork is connected with the inner wall panel of the aluminum mold through the floor corner groove; The bottom of the inner wall panel of the aluminum mold is also hinged with a wall panel brace, and the other end of the wall panel brace is fixed on the ground; The height of the insulation board shall be 50mm higher than the height of the floor where it is located.
The aluminum coil manufacturer believes that the double pull structure can realize the locking of aluminum coil, which is more convenient for installation and has low dependence on the construction experience of workers. The disposable double pull tab is customized according to the wall thickness, and no cement support strip is required, which reduces the process and cost. After the construction is completed, it can be removed by knocking up and down without leaving large holes, and there is no need for later plugging operation.
