Description

TECHNICAL FIELD

[0001] The utility model relates to a house building interior decoration engineering technical field, concretely relates to a kind of ceiling mounting structure for installing backboard and aluminium square tube and the ceiling formed. BACKGROUND

[0002] In modern architectural interior decoration, aluminium square tube and aluminium wave square tube grid ceiling are widely used in business, public and traffic space. This ceiling linear type changes flexibly, and space level is distinct and beautiful. With its unique appearance, excellent performance and diversified design scheme, it is favored by architects and interior designers. However, the existing installation method of aluminium square tube grid ceiling has certain limitations, and the traditional installation has problems such as complex construction, exposed top surface mechanical and electrical pipelines, poor sound absorption effect and difficult to clean accumulated dust. Therefore, a new type of installation structure is needed to simplify the construction process, improve the decoration effect and improve the acoustic performance.

[0003] 1. Traditional installation method of aluminium square tube grid ceiling

[0004] At present, the installation method of aluminium square tube grid ceiling mainly includes two kinds, and there are some problems.

[0005] The first method is to fix the suspender on the main structure or conversion layer at the top by expansion bolts, then fix the notched furring on the suspender by screws, and finally fix the U-shaped aluminium square tube with edge groove at the top into the tooth opening of the notched furring from the side to achieve the effect of overall grid ceiling (as shown in Figure 7 The installation method is connected only by the edge groove at the top of the aluminium plate, so it is suitable for grid ceiling with light weight and small height of square tube.

[0006] The second method is to cut and weld the wave-shaped or strip-shaped aluminium square tube profile into shape, and weld or rivet the fixing part at the top of the aluminium square tube according to the distance and position of the suspender on site. During on-site installation, it is hoisted to the main structure, and the suspender on the main structure is directly inserted into the screw hole of the fixing part, and then fastened on the fixing part by screws, so that the installation is completed. This installation method is mainly borne by the suspender and the fixing part, so it has strong carrying capacity and is more suitable for square tube with heavy weight or high height of profile section. However, there are more high-altitude operations because the hole distance needs to be adjusted after the ceiling plate is hoisted.

[0007] 2. Problems existing in the existing aluminium square tube grid ceiling

[0008] In engineering practice, the two traditional installation methods described above inevitably have some problems, mainly in the following aspects:

[0009] (1) Complex installation leads to long construction time: Square grid ceilings, especially wavy square grid ceilings, require very high construction accuracy. Precise measurement and alignment are required during installation to ensure that the curvature and position of each square are consistent. Otherwise, the waves may be uneven or deformed, failing to meet the design requirements. Traditional installation methods are cumbersome due to the cumbersome installation process, including fixing the keel, arranging the squares, and precise adjustment. For large-area or irregular-shaped ceilings, the installation usually takes a long time, and the installation quality is difficult to guarantee, which also increases the construction period and construction cost of the project.

[0010] (2) The open top leads to poor visual effects: Since the aluminum square tube grid ceiling system is composed of rows of parallel aluminum square tubes or wavy square tubes, it does have a beautiful sense of space and layering when viewed from the side. However, when looking directly upward from the position between the aluminum square tubes, the mechanical and electrical pipelines, ceiling keels, building structures, etc. that should be hidden above the ceiling will be exposed, causing adverse effects on the indoor visual effects.

[0011] (3) Poor indoor noise absorption effect: Compared with high polyester materials or fabric materials, aluminum ceiling corrugated panels have better fire resistance, durability and stain resistance. However, because of its smooth surface, it has poor absorption capacity for indoor noise and is easy to reflect sound, which prolongs the reverberation time in the room, resulting in unsatisfactory noise control effect. In order to achieve good sound absorption effect, it is usually necessary to perforate the aluminum ceiling panels and fill them with sound-absorbing materials. Although this can improve the sound absorption performance, it will destroy the smooth appearance of the aluminum square tube corrugated panels and make them full of holes, thus affecting the overall aesthetics.

[0012] (4) The interior of the ceiling panels accumulates dust and is difficult to clean: Although the aluminum outer surface of the square tube ceiling is not easy to accumulate dust and is relatively easy to clean, its interior is very difficult to clean. Due to the existing installation method, the top of the aluminum square tube is usually an open structure, dust, flying insects, etc. in the air can easily fall into it. Over time, these debris will accumulate inside the aluminum square tube, causing cleaning problems. If you want to thoroughly clean the interior, you often need to remove each aluminum square tube one by one and carry out tedious cleaning work, which is time-consuming and labor-intensive, especially in public spaces or commercial places with high requirements. This maintenance difficulty increases the burden of later management. Therefore, how to effectively prevent dust accumulation in the design and simplify cleaning and maintenance work has become one of the key issues in the design of the aluminum square tube ceiling installation structure.
