Abstract

The invention discloses a construction method for integrally bending and folding a cylindrical external eave aluminum-plastic plate curtain wall and a cross section thereof, which comprises the following steps: (a) manufacturing arc-shaped upper and lower steel frames, enclosing the frames into a cylindrical shape and arranging on the construction site; (b) preparing a plurality of aluminum-plastic plates, wherein an internal groove and an external groove are formed on each of the upper and lower sides of each aluminum-plastic plate respectively; (c) pushing, folding and rotating two outside groove faces of the internal grooves on two sides of each aluminum-plastic plate; (d) pushing, folding and rotating two outside groove faces of the external grooves on the two sides of each aluminum-plastic plate; (e) continuing to push and rotate the two outside groove faces of the internal grooves on the two sides of each aluminum-plastic plate towards the direction of the steel frame to be attached so as to attach to the two inside groove faces thereof respectively; (f) pushing each molding plate so as to completely attach to the upper and lower steel frames; and (g) repeating the steps of (a) to (f) and finishing the decoration. Due to the adoption of the construction method, the construction obstacle is removed, and the construction period, quality and decoration effect are guaranteed.

Description

technical field [0001] The invention relates to a construction method for integral bending and folding, and in particular to a construction method for the cylindrical shape of an aluminum-plastic panel curtain wall on an outer eave and its cross-section integral bending and folding. Background technique [0002] It is very common for aluminum-plastic panels to be used in metal curtain walls and other decorative projects on the outer eaves. There is no problem in the construction on a flat surface, but it is very difficult to construct on a cylindrical shape and its end face or cross-section because it cannot solve the hyperbolic problem. The general solution is to change the method of the base layer. A. Change the steel skeleton into the base layer of a large core board, and then bond the aluminum-plastic board in pieces. This method is used outdoors, because it cannot solve the problem of waterproofing at the seams and sunlight exposure. The warpage problem, thus causing se...
