泡断熱板の断熱性、不燃性の特性を、一般建築物の壁面
に十分生かす事が出来なかった。(Prior art) Conventionally, glass foam insulation boards have sufficient compressive strength, but have the disadvantages of low tensile strength and impact strength, and are brittle and easily chipped. It is rarely used on the walls of general buildings such as buildings.
For special buildings, blocks can be used by adhesively laminating them on the inner walls of refrigerated warehouses, etc., or by laminating them on the bottom of cold storage tanks, etc., as shown in JP-A No. 58-17294. Most of the time, glass foam insulation boards are used for objects, and the heat-insulating and non-combustible properties of glass foam insulation boards cannot be fully utilized on the walls of general buildings.
（発明が解決しようとする課題）
従来、ガラス発泡断熱板を、ビル等の一般建築物の外装
等に単体で用いた場合、以下に示す問題点があった。(Problems to be Solved by the Invention) Conventionally, when a glass foam heat insulating board was used alone for the exterior of a general building such as a building, there were the following problems.
鉄筋コンクリート造建築物の場合、コンクリート打設時
に型枠を兼ねたガラス発泡断熱板はコンクリートの圧力

場合がほとんどである。そして、上記の様にガラス発泡
断熱板をコンクリートの付着力で躯体と緊結できた場合

て、落下を防止する為、アンカーポル１−でガラス発泡
断熱板を躯体に緊結しようとしても、ガラス発泡断熱板
の強度が低い為、支持力が十分得られない。In the case of reinforced concrete buildings, the glass foam insulation board that also serves as the formwork during concrete pouring cannot withstand the pressure of the concrete, and in most cases the glass foam insulation board cracks and breaks. Even if the glass foam insulation board can be bonded to the building frame using the adhesion of concrete as described above, it cannot follow the dry hardening shrinkage of the concrete or the movement of the building structure during earthquakes, and the glass foam insulation board may be destroyed. There is a risk of falling from the body. Furthermore, even when the concrete frame is bonded with an adhesive such as resin mortar, it cannot follow the movement of the frame due to an earthquake, and there is a risk of falling. Even if an attempt is made to fasten the glass foam heat insulating board to the frame using the anchor pole 1- to prevent it from falling, sufficient supporting force cannot be obtained because the strength of the glass foam heat insulating board is low.
鉄骨造建築物の場合、ガラス発泡断熱板をビスで直接躯
体に張設して外装板として用いると、地震時に躯体が動
いた場合、ガラス発泡断熱板のビス部が破壊され、支持
力が低下し、落下する危険がある。In the case of steel-framed buildings, if the glass foam insulation board is used as an exterior plate by directly attaching it to the building frame with screws, if the skeleton moves during an earthquake, the screws of the glass foam insulation board will be destroyed and the supporting capacity will decrease. and there is a risk of falling.
更に、前記いずれの場合も次の様な問題点が生ずる。ガ

時にガラス発泡断熱板が直接炎で熱せられると、亀裂が
発生しやがて落下する。Furthermore, in any of the above cases, the following problems arise. When applying a decorative finish to the surface of a glass foam insulation board, if a finishing material with large shrinkage is used, it will not be able to withstand the shrinkage force, and the glass foam insulation board will be destroyed and the surface finish layer will peel off. If glass foam insulation boards are directly heated by flames during a fire, they will crack and eventually fall.

明の複合断熱板を構成している。In FIG. 1, 1 is a calcium silicate board, 2 is an adhesive, and 3 is a glass foam insulation board. Calcium silicate temporary 1
A material having a specific gravity of 0.8 to 1.0 and a thickness of 4 to 8 cylinders is used; for example, a fiber-mixed cement calcium silicate plate is used. Calcium silicate board l has extremely good dimensional stability compared to slate and the like, and even when bonded to a glass foam insulation board, it will not peel off due to dimensional changes. The specific gravity and thickness of the calcium silicate board are determined by its performance as a composite insulation panel. That is, when constructing a reinforced concrete building, the composite insulation bar 2 is used as a panel that also serves as formwork.
As a result of various studies, including workability, handling, and economic efficiency, calcium silicate plates have a specific gravity of 0.8 to 1.0 in order to withstand the pressure during concrete placement.
Moreover, a material having a thickness of 4 to 8 mm is optimal, and a composite heat insulating panel can be constructed that can also be used for steel structures. Also,
If the calcium silicate board is too heavy, it will easily peel off from the glass foam insulation board. As the glass foam heat insulating board 2, for example, a material made of fired glass-containing material such as obsidian or shirasu, which has a specific gravity of 0.18 to 0.21, is closed-celled, and is nonflammable is used. - For boat fishing, in order to improve the insulation performance, the lower the specific gravity of the glass foam insulation board, the better, but if it absorbs water, the insulation performance will naturally decrease. Therefore, the glass foam insulation board must have closed cells to prevent water absorption. In order to maintain the closed cell nature of the glass foam insulation board, its specific gravity must be
0.18-0.21 is optimal. As adhesive 3,
For example, a synthetic resin adhesive, more specifically a solvent-based synthetic rubber adhesive containing toluene and n-hexane as components, is preferred. The calcium silicate plate 1 and the glass foam heat insulating board 2 are fixed together with an adhesive 3 to constitute the composite heat insulating board of the present invention.

In FIG. 2, 4 indicates a reinforcing sheet. The reinforcing sheet 4 is made of a material with high breaking strength, such as a composite sheet made of synthetic resin adhesive and kraft paper, preferably, but if water resistance is required, an asphalt felt sheet that does not absorb water is used.

With this configuration, the tensile strength of the glass foam insulation board 2 is improved, and the performance of the composite insulation panel is further improved.

的に優れたパネルとなる。(Effects of the Invention) The composite heat insulating panel of the present invention has the following effects. That is, a glass foam insulation board with a specific gravity of 0.18 to 0.21 and a glass foam insulation board with a specific gravity of 0.8 to 1.0 and a thickness of 4 to 8 m.
By bonding and fixing the calcium silicate plate as one piece, the calcium silicate plate can easily bend.
This improves the low tensile strength of glass foam insulation boards, resulting in panels with superior strength.

発明の複合断熱パネルによると、躯体に緊結され落下す
る危険がない。For example, when constructing a reinforced concrete building, the composite insulation panel of the present invention can be used as a formwork, that is,
The bending force applied to the formwork due to the lateral pressure of concrete when directly pouring concrete can be easily borne because the calcium silicate plate bears the tension side and the glass foam insulation plate bears the compression side. It is possible to configure external heat insulation walls, etc. Also, when tightening with anchor bolts to a concrete frame or directly installing with screws on a steel frame building,
The local compressive force of the calcium silicate plate is large, and the compressive strength of the glass foam insulation plate that receives it is high, so the synergistic effect of making it into a body makes it possible to increase the supporting force of the screw head, making it possible to improve the anchor bolt. The head diameter and number of screws can be left unchanged, and even if the building block moves due to an earthquake, the composite heat insulating panel of the present invention is secured to the building block and there is no risk of it falling.

ルの性能を維持できる。Furthermore, when applying a decorative finish to the surface of the composite heat insulating panel of the present invention that is fastened to a building frame, the calcium silicate temporary strengthens the surface of the glass foam heat insulating board, making it possible to apply any decorative finish. In addition, in the event of a fire, the glass foam insulation board is not directly heated by the flame and does not melt and fall, providing excellent fire resistance. Finally, the glass foam insulation board has a specific gravity of 0.18 to 0.21 to maintain closed cell properties and does not absorb water, so it maintains its insulation properties over a long period of time.In addition, the calcium silicate board has dimensional stability. Because of its good properties, it maintains integrity with the glass foam insulation board, allowing the performance of the composite insulation panel to be maintained over a long period of time.
