The technology of the Dry hanging aluminum plastic composite panel construction

(1) Construction stringing according to the actual civil engineering center line and elevation point; The design of the decorative surface is based on the axis of the building. The aluminum plastic plate skeleton is composed of horizontal and vertical parts. The position line of the vertical bar is played well first, and then the anchorage point of the vertical bar is determined.

(2) install fixed connectors. Fix the connector by electric welding, and apply anti-rust paint twice at the welding seam. Weld fixed connectors to embedded parts on the main structure. When the embedded iron parts are not embedded in the main structure, expansion bolts can be drilled into the main structure and fixed with the connecting iron parts.

(3) install the skeleton. Install the skeleton by welding. Check the elevation and center line position at any time during installation, and use anti-rust paint to deal with the welding seam at the section connection. Fixed fittings and made a hidden inspection record, including the length, thickness, position of the welding seam of fittings, buried elevation, quantity and embedded depth.

(4) install aluminum plastic composite panel on the internal frame of the profile. Firstly, tap and mill the screw hole position, and fix the aluminum plastic plate veneer on the profile steel frame block by block with rivets; Gap between plates for 10 ~ 15㎜injected silicone weathering sealant; It is strictly prohibited to remove the wrapping paper before the installation of aluminum plate. According to the direction of aluminum plastic arrow construction.

The dry-hang of the aluminous model board : do the foundation first. After finishing foundation, calculate the dimension of face plate according to dimension, and process the face plate, which is called professionally dish. First, make the base material, add 4cm to the length and width of the base material, and then use the special trimming machine on the back of the aluminum plastic composite panel, in each side of 2cm, make the hem seam 2 times thicker than the aluminum plastic composite panel , cut off any excess corners, and then fold the edges over, making sure they're right angles. Fixed with 1·5 * 1·5 * 1·5cm aluminum seven-word Angle (drilling with 4·2 bit, reinforce with the rivets). Hang dish now, fix aluminous model board on metope foundation with fast nail and special piece, put apart corresponding glue seam, which enables to hang from up or down.

It should be noted that the frame should be flat, vertical and square with a dimension error of about 5mm. Aluminum plastic composite panel should be square, the direction should be consistent, and the error should be controlled in about 3mm. Glue from top to bottom, first fill with foam bar, and then injection of glue, with greasy knife pressure, tear off the protective film.

According to industry standards, the thickness of aluminum plastic composite panel is generally more than 3mm, 3mm aluminum plastic composite panel thickness to 10 wire (that is, 0.1mm) more than 10, indoor aluminum plastic plate is generally 3mm, aluminum thickness has 10 wire, 15 wire, 21 wire, such as the concentration of commonly used thickness.

General aluminum plastic composite panel common aluminum thickness has the following several kinds.

Facade materials: 0.20mm, 0.30mm and 0.40mm, and 0.50mm. 0.30mm and 0.40mm are the most common.

The interior facades are made of materials with a wide range of aluminum thicknesses of 0.15 and 0.12-0.10 mm structures.
