Problems solved by technology

[0005] CN2581572Y discloses the composite cored type fire wall body plate, the specific structure is to set the thermal insulation core layer in the surface layer on both sides, the wall body plate of this structure has the shortcoming of taking care of one thing and sacrificing the other, that is, although it has fireproof effect, its strength It is fragile, and it does not have the effects of environmental protection, energy saving, sound insulation, resource reuse and earthquake resistance
[0006] Compared with CN2581572Y, the lightweight sandwich composite wall panel recommended by CN2677483Y has improved strength due to the ribs between the two panels, but it is still not enough to eliminate the other defects of CN2581572Y
[0007] CN2908640Y discloses that the rice / wheat straw fiber bundle as the inner core combined wall panel has the advantages of energy saving, environmental protection and resource reuse, but its disadvantages are heat insulation and fire prevention, sound insulation and poor strength

Embodiment 1

[0026] Please see figure 1 , The first and second board bodies 1 and 2 are given. The first and second board bodies 1 and 2 are crushed by plant straws and mixed with an adhesive, and then pressed into a mold. Of course, you can also use pure wood chips to add adhesive to mix well and put it into a mold to form the shape, and also use straw glass magnesium board, and the straw glass magnesium board is a composite hollow structure. The hollow structure mentioned here is like a honeycomb shape. In this embodiment, when the first plate body 1 is made, there is formed on the peripheral edge portion of the surface of the first plate body 1 facing the second plate body 2 a complement which protrudes obviously from the first plate body 1. The strong frame 4, that is, the reinforcing frame 4 is integrally formed on the first plate body 1. Reinforcing ribs 41 are formed between the reinforcing frames 4 and spaced in the longitudinal direction of the first plate body 1, and the distance...

Embodiment 2

[0029] Please see figure 2 with image 3 , Between the first and second plate bodies 1, 2 is added a sealing frame 5 that matches the size of the first and second plate bodies 1, 2. The material of the sealing frame 5 is preferably the same as that of the first and second plate bodies. The materials of 1 and 2 are the same. In the central area of ​​the sealing frame 5 and the longitudinal direction of the first and second plate bodies 1, 2 are provided with reinforcement strips 51 at intervals, and the two ends of each reinforcement strip 51 are connected with the sealing frame 5 Due to the presence of the reinforcing strips 51, a pad cavity 511 is naturally formed between adjacent reinforcing strips 51, and a flame-retardant heat insulation board 3 is laid in each pad cavity 511. In this embodiment, for the reinforcing strip 51, a metal tube having a rectangular cross-sectional shape is preferably used, but not absolutely limited. The distance between adjacent reinforcing bar...

Abstract

The invention relates to a composite wall board, belonging to the technical field of prefabricated members of buildings. The composite wall board comprises a first board body and a second board body which are fixed face to face with each other and a flame retarded insulation board located between the first board body and the second board body, wherein the first board body is towards a side surface of the second board body, or the second board body is towards a side surface of the first board body to form a reinforcement frame protruding the surface of the board body, reinforcement ribs are formed in the reinforcement frame in the interval state, and a padding cavity is formed between every two adjacent reinforcement ribs and the flame retarded insulation board is laid in the padding cavity, wherein the first board body and the second board body are plant straws boards, sawdust boards or straw glass magnesium boards. The invention has the advantages of simple structure and convenient making; the used materials are environmental friendly and energy saving; the strengths of the first board body and the second board body can be ensured through the arrangement of the reinforcement frame and the reinforcement ribs or edge sealing frames and reinforcement bars; and the flame retarded insulation board can achieve ideal fireproof and energy saving effects.

Description

Technical field [0001] The invention belongs to the technical field of prefabricated components of buildings, and particularly relates to a composite wall panel. Background technique [0002] Composite wall panels have been widely reported in the literature, especially in the Chinese patent literature. The Chinese Utility Model Patent Authorization Announcement Number CN2806622Y introduces a hollow environmentally friendly composite lightweight wall panel, which is generally composed of a pair of opposed to each other Both ends of the Z-shaped board in the longitudinal direction are provided with grooves with a tenon effect, a through hole is arranged between the middle of the longitudinal direction of the board, and the hole is filled with thermal insulation material, and metal meshes are embedded on the upper and lower end surfaces of the board. The moisture-proof soundproof board. Although the board of this structure has the advantages of lightness, it is not only troublesome...
