Dry hanging aluminum plate construction technology
① put the line work according to the actual construction of the centerline and elevation point; design of the facade of the building based on the axis of the aluminum-plastic panel frame composed of horizontal and vertical pieces, the first good vertical rod position line, and then Anchor points for vertical bars are defined.
②, the installation of fixed connectors On the basis of pay-off, with electric welding fixed connectors, rust-proof paint second place. The connecting piece is welded and fixed with the embedded parts on the main structure, and when the main structure is not embedded with the embedded iron piece, an expansion bolt and a connecting iron piece can be perforated on the main structure to be fixed.
③, the installation of skeleton welding method to install the skeleton, installation at any time check the elevation, the centerline position, and at the same time the cross-section weld to do anti-rust treatment, fixed connectors do hidden inspection records, including the weld length, thickness, Set the standard height, the number of embedded depth.
④, install the aluminum plate in the profile rack, the first milling screw hole bits, the rivets to the aluminum panel veneer block-by-block in the steel frame; the gap between the plate and the board is 10 ~ 15 mm and then injected silicone Weatherable sealant; aluminum packaging is strictly prohibited before dismantling the packaging paper, until the completion of the front ripped packaging protective film; according to the direction of aluminum-plastic arrow construction.
Dry hanging aluminum panels, the first to do wall base, angle steel, square tube, aluminum square tube, curtain wall special material. After finishing the foundation, according to the size of the panel to calculate the size, began to process the panel, professional said dish. First out of the substrate, the substrate length and width are plus 4cm, and then with a dedicated trimming machine in the back of the aluminum plate, 2cm at each side, repair the thickness of the aluminum plate 2 times the flange Seam, cut off the extra part of each corner, and then fold the edge over, must be at right angles, with 1.5 × 1 · 5 × 1 · 5cm aluminum seven corners fixed (drill with 4.2 drill bits, Rivet reinforcement). Now you can hang the plate, with fast nails and special pieces of aluminum plate fixed on the wall, leaving the appropriate glue seam, since the bottom can be linked.
It should be noted that: the framework should be flat, vertical, into a square, the size of the error is about 5mm. Aluminum plate plate to party, the direction should be consistent, the error control in 3mm or so. To glue from top to bottom, first filled with foam rods, and then plastic injection, with a flat knife flat, tear off the protective film.
In accordance with industry standards, the thickness of aluminum-plastic panels generally more than 3mm, 3mm aluminum-plastic aluminum thickness to 10 filaments (that is, 0.1mm) above, the indoor use of aluminum-plastic panel is generally 3mm, aluminum thickness 10, 15 Silk, silk and other common concentrations of 21.
Common aluminum plate aluminum thickness are as follows.
Façade materials, with 0.20 mm, 0.30 and 0.40 mm, and 0.50 mm these four. Of which 0.30 and 0.40 most common.
The material for the façade, with 0.15 and 0.12-0.10 mm thick aluminum structure of such a wide range.
