Description

[Detailed Description of the Invention] This invention relates to a heat insulating composite board, particularly a heat insulating composite board that can also be used as a concrete formwork.

A typical example of this type of conventional heat insulating composite board is a heat insulating composite board 11 as shown in FIGS. 1 to 3.
It is possible to raise at least two of them by integrally laminating the cement board 13 on the foam insulation material 12.
A concave groove 14 parallel to the surface of the cement board 13 is provided at the peripheral end portion of the cement board 13 in a portion that corresponds to the back surface of the cement board 13.

When using such a composite plate 11, as shown in FIGS. 2 and 3, two adjacent composite plates 11 are arranged so that their peripheral edges abut, and the opposing concave grooves are aligned. 14 to connect the composite plates 11 together, and in this way connect the composite plates one after another vertically and laterally to form a composite plate assembly with desired dimensions. do.

Then, at a predetermined distance from this composite plate assembly,
Formwork materials 17 are placed facing each other, reinforcing bars (not shown) are placed between the assembly and the formwork materials as necessary, and concrete 18 is poured to form a concrete wall. By removing the formwork 17, a heat insulating wall in which the composite board 11 and concrete 18 are combined can be obtained.

However, in the case of such a composite board 11, the grooves 14 are provided in the foam insulation material 12, and the insulation material 12 is fragile, so when a load is applied to the composite board 11 during assembly of the composite board, the insulation material 12 is missing,
There was a drawback that the bonding strength between the composite plates 11 was reduced.

The purpose of this invention is to eliminate the drawbacks of the conventional composite plates as described above, and to provide a composite plate that does not reduce the bonding strength between the composite plates.

In order to achieve the above-mentioned object, this invention uses a fiber-reinforced cement board as a cement board, and provides thick walled parts made of the same material as the cement material on at least two circumferential edges of the cement board. It is characterized by having a groove parallel to the surface of the cement board approximately in the center of the meat part.

An embodiment of this invention will be described with reference to FIG. 4 and subsequent figures.

Reference numeral 1 indicates a heat insulating composite board according to this invention, which is composed of a foam heat insulating material 2 integrally laminated with each other and a cement board 3 reinforced with fibers such as glass fiber. In the drawing, the cement board 3 is provided with a thick wall portion 5 made of the same material as the cement board 3 at the upper and lower circumferential ends, and a groove 4 is formed approximately in the center of the thick wall portion 5 in parallel with the surface of the cement board 3. is provided. In this case, the thick portion 5 is also provided at the side circumferential end,
A concave groove may be provided on the entire circumferential edge.

When using such a heat insulating composite board 1, the fifth
As shown in the figure, a formwork material 17 is used to create an insulating wall in which concrete 18 and composite board 1 are combined. 1 is arranged with predetermined joints, 19 is a sealant for the joints, 2 is a sealant for the joints,
0 is a foam insulation material for joints.

This idea is as described above, and the cement board is a fiber-reinforced cement board, a thick part is provided at the joint peripheral edge, a groove is provided in the thick part, and this groove is utilized. Since the heat insulating boards are joined together, the concave grooves will not be cut when joining the heat insulating boards, resulting in a strong joint. This eliminates inefficiencies such as overlapping, and increases work safety because one of the composite boards does not fall or wobble during work. Also, the thick wall part reinforces the peripheral edge of the cement board. Therefore, even if force is applied to the joints between composite boards during concrete pouring, it can be adequately resisted, and even if the cement boards were to separate from the insulation material, There are many excellent effects such as being held by other adjacent cement plates by the connecting member.
