Problems solved by technology

[0005] 1) The screw at the fixing point penetrates, and the nail hole is deformed due to thermal expansion and contraction for a long time, resulting in water leakage;
[0006] 2) There are joints at the joints of the boards, which is easy to form siphon water seepage, or the roof overflows due to excessive rainwater leakage
[0011] 3) The plate type with undercut connection cannot be replaced with the damaged plate type arbitrarily
[0012] But it has the following problems: the undercut force cannot be calculated, and the quality of the undercut is affected by the construction level and the environment on site. If there is a bad bite point, it will be exposed to the overall roof wind. At present, many roofs in China are caused by this system. roof damage
Metal enclosure systems are widely used, but they have fatal flaws: water leakage, wind exposure

Embodiment 1

[0044] Such as figure 1 and figure 2 As shown, the metal enclosure system of the present invention includes at least two overlapping film-coated metal sheets 1, and the two film-coated metal sheets are overlapped at the edge; A support structure 2 is provided; a fixing nail 3 is nailed through the overlap of two layers of coated metal sheets so that the two layers of coated metal sheets are nailed to the support structure 2; a welding film is covered on the overlap of the two layers of coated metal sheets 4. The two sides of the welding film are welded on the two layers of film-coated metal sheets near the seam to form a welding seam 8 .

[0045] The above-mentioned welding refers to welding the welding film and the coating on the two-layer coated metal sheet, and ultrasonic welding commonly used in plastic welding can be used.

[0046] A foam heat insulation and noise reduction layer 5 is provided on the inner surface of the trough of the metal profiled sheet 1 . Wherein,...

Embodiment 2

[0059] The construction method of the film-coated metal sheet of the present invention, the described construction method is:

[0060] Lap two laminated metal sheet edges over a purlin or support structure;

[0061] Nails or screws are used to penetrate the two layers of film-coated metal sheets so that the two layers of film-coated metal sheets are nailed to the purlins or supporting structures;

[0062] Cover the lap joints with a welding film identical or similar to that of the coated sheet metal;

[0063] The sides of the welded film are welded to the film on the two laminated metal sheets.

[0064] Above-mentioned thin plate can be profiled thin plate, as figure 1 figure 2 The metal sheet shown is a profiled sheet, which has crests and troughs; the crests of the two coated metal sheets are overlapped, and the nails or screws are nailed through the two layers of coated metal sheets to make the two layers The crests of the film-coated metal sheets are nailed to the pur...

Abstract

The invention discloses a film-coated metal sheet metal containment system and a construction method thereof, and the film-coated metal sheet metal containment system is invented to solve the problem that the prior art is high in cost. The film-coated metal sheet metal containment system at least comprises two lapped film-coated metal sheets, and the two film-coated metal sheets are lapped on the edges; a supporting structure is arranged below the two film-coated metal sheets; one fixing nail is nailed through the lapped part of the two film-coated metal sheets so that the two film-coated metal sheets can be nailed to the supporting structure; a lapped seam of the two film-coated metal sheets is covered with a welding thin film, and the two side edges of the welding thin film are welded to the portions, close to the lapped seam, of the two film-coated metal sheets. The film-coated metal sheets are suitable for various metal containment systems including a roof and the like.

Description

technical field [0001] The invention relates to a metal enclosure system and its construction method. Background technique [0002] There are many ways to use the existing metal plate as the roof, and the lapping methods that are widely used at present are as follows: [0003] 1. The metal plate is lapped and fixed on the purlin with self-tapping screws [0004] This method has the advantages of firm fixing and easy construction, but it also has the following problems: [0005] 1) The screw at the fixing point penetrates, and the nail hole is deformed due to thermal expansion and contraction for a long time, resulting in water leakage; [0006] 2) There are joints at the lap joints of the boards, which is easy to form siphon water seepage, or the roof overflows and leaks due to excessive rainwater. [0007] 2. Fix it on the purlin with a bracket, and connect the bracket with the undercut of the metal plate [0008] This structure has the following advantages: [0009] 1...
