Description

Composite sheet

technical field

The utility model mainly relates to the field of building components in civil engineering, in particular to a combined board that can be used as a floor slab, roof slab, outer wall, partition wall and room partition wall of a building.

Background technique

With the development of society and the continuous improvement of people's living standards, new requirements are put forward for housing, which is mainly manifested in the requirement that the housing space can be flexibly separated to meet the individualized functional requirements. Traditional masonry walls, reinforced concrete walls, and floor slabs cannot meet the requirements of flexible space separation due to the shortcomings of complex construction and heavy weight. With the emergence of various lightweight building materials, many new lightweight walls have been developed and gradually applied to practical projects. At present, there are three main types of new lightweight walls:

1. Lightweight partition wall with light steel keel paper surface gypsum board. This kind of partition wall is composed of industrially produced thin-walled steel to form a load-bearing skeleton. Paper-faced gypsum boards are installed on both sides of the skeleton, and then the middle of the two layers of gypsum boards is filled with thermal insulation and sound insulation materials to form a partition wall. The outer layer of the plasterboard can be Paint the walls for interior decoration. This kind of partition wall has the advantages of fast construction speed, light weight and low cost, so it is widely used at present;

2. The double-sided steel wire mesh of lightweight foam board is coated with polymer mortar and steel frame partition wall. The most representative of this type of partition is Thai clapper. The core material of the partition wall is foam board, which has the functions of heat preservation and sound insulation. A light steel frame is installed on both sides of the foam board to form a load-bearing system, and then steel wire mesh is hung on the outside of the frame, and polymer mortar is applied to form a surface layer. Therefore, this partition wall has high strength. Due to the specialization of construction, the construction period is short and the quality is guaranteed;

3. Color profiled steel wall. This kind of wall is mainly used in industrial plants with steel structures. The main load-bearing components of the wall are steel purlins, and the wall material is colored profiled steel plate, and the two are connected by bolts. The inside of the wall is thermally insulated by installing glass wool and other materials. The construction speed of this kind of partition wall is very fast, and its own weight is also light.

Although all kinds of new partition walls have the advantages of light weight and convenient construction, there are also some shortcomings:

1. There are limitations in the scope of use. The above three kinds of lightweight partition walls have their own scope of use. Due to the problems of the material itself, the light steel keel paper-faced gypsum board wall and Thai cladding board cannot be used for exterior walls; and the colored profiled steel plate wall is not suitable for residential partition walls. All kinds of lightweight partition walls can only be used as walls and cannot be used as load-bearing floors.

2. The building materials themselves are not environmentally friendly. The main load-bearing structural materials of the above three types of lightweight partition walls are all steel, and the amount of steel is relatively large, which is a product of high energy consumption and high pollution industries in my country. my country's steel production technology and equipment are relatively backward, and the environmental protection equipment of the factory is not perfect. The production of steel needs to consume a lot of energy, and at the same time generate a lot of waste water, waste gas and waste residue, which seriously affects the ecological environment and does not meet the requirements of sustainable development. . As far as Taipai board is concerned, its core material is foam material, which itself is a source of white garbage and cannot be degraded naturally. It is also used as a partition wall and has the problem of poor fire resistance. Today, when sustainable development is vigorously advocated, "green building" is an inevitable choice. It is necessary to innovate new types of walls, innovate materials, and develop green board structures.
