Description

Mounting structure of tectorial membrane metal clad sheet

Technical Field

The utility model relates to a dalle technical field, concretely relates to tectorial membrane metal clad sheet's mounting structure's technique.

Background

Both aluminum-plastic plates and film-coated metal composite plates are decorative plates for interior decoration. Wallboard, suspended ceiling and floor are all using, and how be difficult for falling after quick installation becomes the problem that needs to solve. For example, chinese patent application No. 201420455220.9, entitled decorative panel connecting profile, discloses that the decorative panel connecting profile comprises a bottom plate, a first limit baffle and a second limit baffle vertically arranged left and right are arranged on the surface of the bottom plate, and a partition plate is formed between the first limit baffle and the second limit baffle; the baffle is located in the middle of first limit baffle and the second limit baffle, the height that highly is not higher than first limit baffle and second limit baffle of baffle, the left surface and the right flank of baffle are provided with third sawtooth and fourth sawtooth respectively, form first embedded groove between first limit baffle and the baffle, form the second embedded groove between second limit baffle and the baffle. The decorative plate connecting section bar with the structure has the following defects:

1) after the inserting part of the decorative plate is inserted into the embedding groove, the decorative plate is easy to loosen. The reason is that the first limit baffle and the second limit baffle are both vertically arranged, the profile is formed and then has certain strength without elastic force, and the slippage is prevented by only relying on the sawtooth structure. For preventing the pine from taking off, can shorten the distance between first limit baffle and the second limit baffle, realize the interference installation and play fixed effect, but the installation is to need the decorative board of heavy pressure equipment like this, if the decorative board has thickness inequality, still can unable installation, probably harm the decorative board at the decorative board of heavy pressure equipment, can produce the deformation at least, also drops easily after the installation, consequently still need beat the problem that the processing just thoroughly solved and easily drops.

2) The specification also discloses a structure without a partition in the middle, and one advantage of the connecting profile is that the two decorative plates are in a sticking state, the installation effect is more widely used, and due to the structure without the partition, the sawtooth structure on the partition is reduced to prevent slipping, and as a result, the fixing effect of the partition is lower.

3) The decorative plate is used for ground installation, and the technical content disclosed in the specification indicates that the connecting section bar is required to support, so that the strength of the connecting section bar is necessarily required to be enhanced, namely, the thickness is increased, the material consumption is caused, and the cost is increased.

4) There is the difference based on doing work of decorative board, and the installation technology also has the difference, and the installation stability of decorative board also can receive the influence because the fixed first limit baffle and the second limit baffle of decorative board are undertaken.

5) If first limit baffle and second limit baffle are difficult to produce clamping-force or the cartridge portion deformation of decorative board and influence holistic level effect, prior art is difficult to solve this technical problem.
