Fireproof composite wall for building protection

Abstract

The invention discloses a fireproof composite wall for building protection. The simple wall comprises a bearing wall (1); multiple prestress dispersion layers (2) are transversely bonded on the two sides of the bearing wall (1) end to end; sandwich layer fillers (3) are cast in two space formed by the prestress dispersion layers (2) and the bearing wall (1); the sandwich layer fillers (3), the prestress dispersion layers (2) and the bearing wall (1) are integrally injected to form a simple wall main body. The simple wall is simple in structure and novel in design, improves the earthquake resistance of the overall wall structure, reduces the design strength and cost of wall components, meanwhile, greatly improves the shear resistance and the integrity, and has such advantages as excellent integrity, excellent earthquake resistance, higher bonding and anti-shearing capacity and excellent finished wall molding effect.

Description

technical field [0001] The invention relates to a wall body, in particular to a fireproof composite wall body for protecting buildings, and belongs to the technical field of general fixed building wall body structure. Background technique [0002] Generally speaking, the traditional wall is made of calcium silicate board or the traditional wall is a concrete prefabricated board. Due to its poor connection, heavy weight and weak load-bearing performance, there are many shortcomings. Wet work construction, heavy wall body, can't realize assembly and modern energy saving and environmental protection practicality. [0003] At present, the partition walls on the market can be divided into: [0004] The first is the masonry partition wall, which refers to a structure that uses bricks, stones or blocks as materials and is built with mortar, such as: brick walls, aerated concrete blocks, and ceramsite bricks. The materials for this structure have a wide range of sources. It is eas...

Problems solved by technology

[0004] The first is the masonry partition wall, which refers to a structure that uses bricks, stones or blocks as materials and is built with mortar, such as: brick walls, aerated concrete blocks, and ceramsite bricks. The materials for this structure have a wide range of sources. It is easy to obtain local materials and has good water resistance and durability; its disadvantages are: heavy weight, low strength, poor earthquake resistance and crack resistance, and heavy masonry work;

[0005] The second is the GRC type lightweight partition wall, which is a wall material that looks like a hollow wall. It has the characteristics of light weight, high strength, fire prevention, and rapid construction; its disadvantages are: poor sound insulation, easy to crack, Seismic difference;

[0006] The third type is that the skeleton partition wall mostly uses light steel keel or wooden keel as the skeleton, and gypsum board and asbestos cement board are nailed on the outside. The density is the lowest, in addition, its service life is short, generally only 2 to 3 years;

[0007] The fourth type is lightweight composite sandwich slats, which use fiber-reinforced silicon-calcium boards or cement-silicon-calcium boards as panels, and are filled with lightweight core materials in the middle to form a lightweight and energy-saving composite board. quality, thin body, high strength, impact resistance, strong hanging force, heat insulation, sound insulation, fire prevention, waterproof, easy to cut, can be slotted arbitrarily, no need to paint, dry operation, etc., but the disadvantage is short life, lap joints Easy to deform, high cost;

[0008] The fifth is that the ceramsite board has the characteristics of high strength, not easy to cut, and large loss, but its weight per unit area is the heaviest among light partition walls, so the processing cost is also high;

It is characterized by good lighting, but it is more practical for places with poor lighting, but the cost is very expensive;

[0010] The seventh type is soil-fired brick or soil-fired porous brick, cement mortar brick or cement square hole brick, aerated block brick or fly ash brick, etc. The advantages and disadvantages are as follows: First, the advantages of soil-fired brick or soil-fired porous brick It is fired with clay using ancient techniques, does not burn, has strong load-bearing capacity, and is resistant to aging. The disadvantages are that soil resources are scarce, and the production process is cumbersome. When firing bricks, it consumes a lot of energy and produces a lot of waste gas. At the same time, the wall Heavy weight, high technical requirements during on-site construction, the main material needs a lot of auxiliary materials to complete, the main material and auxiliary materials occupy a large area during transfer, and will generate a lot of dust and blown sand to pollute the environment; the second is cement mortar bricks or cement The advantage of square hole bricks is that it is made of mechanized pressing, does not burn, and has a strong load-bearing capacity. The disadvantage is that the wall is heavy and requires high technical requirements during on-site construction; It is made of foaming agent, does not burn, and the wall is light in weight. The disadvantage is that the surface of the wall has low strength and large water absorption. During the rainy season and rainy season, the wall will turn yellow or mildew. Can not directly pave tiles and marble

[0011] At the same time, the plane area of ​​the concrete wall in the building structure is large, and there are difficulties such as large tonnage, difficult transportation, and inconvenient hoisting during construction;

[0012] The eighth type is a light-weight wall composed of foam boards and steel wire mesh boards. Although it has the characteristics of light weight and fast construction, its disadvantages are: poor sound insulation, easy cracks, poor earthquake resistance, short service life and overlapping joints. easily transformed;
