Embodiment 1

[0021] Such as figure 1 with figure 2 As shown, a composite board includes two oppositely arranged board bodies 1, keels 2 respectively fixed on the two board bodies 1, and an insulating core material 3 filled between the two board bodies 1, wherein one board body 1 The keels 2 of the two boards 1 are separated from each other with a gap between them, and the keels 2 on the two boards 1 are separated from each other with a gap between them, and the above gaps are provided with insulation Core material 3, the thermal insulation core material 3 of this embodiment is a core material made of cementitious material, such as a thermal insulation core material made of perlite and gypsum, or a thermal insulation core material made of cement, ceramsite and perlite, or Insulation core material made of sodium silicate and vermiculite; plate body 1 is a panel; the keels on the two plate bodies 1 are distributed in parallel, and the keel 2 is a C-shaped keel in the light steel keel, and t...

Embodiment 2

[0023] Such as image 3 As shown, on the basis of Example 1, in this embodiment, the thermal insulation core material 3 is a core material made of a polymer foam material, such as a core material made of a foamed polyethylene board or a foamed polyurethane material. The core material, the keel 2 is a Z-shaped keel, the lower flanks of the Z-shaped keel are fixed to the plate body 1 by bolts or self-tapping screws, and the keels on the two plate bodies 1 are staggered to avoid forming cold bridges.

Embodiment 3

[0025] Such as Figure 4 As shown, on the basis of Embodiment 1, in this embodiment, the keel 2 includes a straight plate, a curved portion arranged on the upper part of the straight plate, and a side wing arranged on the lower part of the straight plate. The curved parts on the upper part are arranged in pairs facing each other, and interlocked with each other through the heat-preservation core material.

Abstract

A composite plate comprises two oppositely installed plate bodies (1a, 1b) having keels (2a, 2b) fixed thereon, respectively, and having a heat preservation core material (3) filled therebetween, wherein the keel (2a) on the plate body (1a) and the other plate body (1b) are separated from each other, and the keels (2a, 2b) on the two plate bodies (1a, 1b) are also separated from each other; in addition, keels (2a, 2b) both have flexures (4) which are inserted into the heat preservation core material (3) for securing. The composite plate has a high integral intensity and the problem of cold bridge caused by the metal keel is avoided.

Description

technical field [0001] The invention relates to a composite board. Background technique [0002] Existing composite panels mainly include keelless composite panels made by bonding cementitious materials in lightweight core materials or composite panels connected by keels. The first type of composite panels is fixed by the adhesive force of materials. Risk and uncertainty of bonding failure, especially when applied to exterior walls, there is a possibility that the surface layer may fall off; although the second form of composite board solves the problem of the overall strength of the composite board, due to the coldness of the metal keel Bridge problems, poor thermal insulation, and wooden keels have problems such as moth-eaten, easy to rot, and not strong. Contents of the invention [0003] The object of the present invention is to provide a composite board, which improves the connection strength between the boards and solves the problem of poor thermal insulation perfor...
