Description

[Detailed Description of the Invention] The present invention relates to a composite board for construction that has heat insulation properties, an air cycle function, and fire retardant properties necessary for use as internal and external wall materials for buildings and structures.

Due to the spread of energy conservation laws, etc., the use of insulation materials in buildings is steadily increasing. However, the state of construction of the heat insulating material in this type of building has generally focused solely on heat insulating properties. As a result, for example, dew condensation occurs in houses, corroding constituent materials, deteriorating the performance of insulation materials, staining furniture, clothes, etc., and deteriorating the indoor environment, which have become major problems. The causes of this type of problem include: (a) Insufficient insulation of the outer wall of the building, (b) Insufficient ventilation between various parts, (c) Insufficient circulation of air inside the building, and (d) Inadequacy of the moisture barrier layer. This is due to

In order to eliminate these drawbacks, the present invention uses a synthetic resin foam with a closed-cell foam structure between the impermeable base material and the sheet material, recesses for air cycles, and a special sheet material that allows air cycles to be performed at each location. We propose a composite board for construction that is formed integrally with the above-mentioned functions ○I to ○2 to prevent condensation from forming inside and outside the building, and has enhanced durability. do.

An embodiment of the architectural composite board according to the present invention will be described in detail below with reference to the drawings. In Fig. 1, 1 is a main body made of a thin metal plate with a concave cross-section and a long rectangular shape, and mainly consists of a surface material,
It functions as a decorative material (embossed board, ricin-coated board). Reference numeral 2 denotes a male connecting portion having an insertion edge 3 projecting outward from one end of the main body 1; 4 denotes a female connecting portion having the other side edge of the main body 1 bent inward;
An insertion groove 5 is provided to protrude outward again, and a lower edge 6 of the insertion groove 5 is extended outward to form an extension 7. Reference numeral 8 denotes a protrusion, which is provided as necessary in the middle of the extension part 7, and 9 and 10 are tongue pieces formed at the insertion edge 3 and the tip of the extension part 7 as shown in Fig. 2 a to h. It functions as a drainer and to prevent workers from getting injured when constructing and transporting composite boards for construction, and also serves to impart elasticity to the joints of composite boards and strengthen the bonding force. 1
1 is a heat insulating layer filled in the concave shape of the main body 1, and is made of one or more of, for example, polyurethane foam, polyisocyanurate foam, phenol foam, polystyrene foam, polyethylene foam, etc.; ,
Or by in-situ foaming method. In addition, from the viewpoint of fire prevention and heat insulation properties, polyisocyanurate foam and phenol foam, which have a closed cell structure and form a carbonized layer, are preferable. Reference numeral 12 denotes a recess provided in the center of the back surface of the heat insulating layer 11 parallel to the side wall of the main body 1. This recess 12 is formed, for example, as shown in FIGS. 3a to 3c. 13 is a sheet-like material that is stretched from the back surface 2a of the insertion edge 3 to the back surface of the extension part 7, and is made of aluminum foil and sheet materials (asphalt felt, synthetic resin film, waterproof kraft paper). , asbestos paper), and covers the inner vicinity of the back surface of the heat insulating layer 11 and the back surfaces of the male and female connectors 2 and 4, and has micropores 14 in the size of microns to millimeters, for example, in the portions corresponding to the recesses 12. The holes are drilled in a high-coarse-high density manner. In particular, the upper and lower ends of the architectural composite board are perforated with high density, and the space between them is perforated with coarse density distribution. Reference numeral 15 denotes an air cycle path, which is an air gap surrounded by the recess 12 of the heat insulating layer 11 and the sheet material 13, which connects the attic 16 and the underfloor 17 as shown in FIG. →It is designed to cycle low-temperature air. Moreover,
Air is taken in and exhausted from the air cycle path 15 not only from the upper and lower ends but also from the middle through fine holes that are roughly distributed.

Next, a construction example will be explained.

That is, it is assumed that the outer wall of a building is formed using architectural composite boards as shown in FIG. Therefore, as shown in Figure 5, the architectural composite board A ₁ is attached to the nail B.
It is fixedly installed on the body rim C through. Next, the insertion edge 3 of the architectural composite board A ₂ is inserted into the insertion groove 5 of the architectural composite board A ₁ . In order to form the outer wall etc. in this way, the above operations may be repeated in sequence. In addition, in the vertical direction (base, girder), the air cycle path 15 is
The openings at both ends are closed to allow an air cycle between the attic 16 and the underfloor 17. With this structure, there is no condensation on the exterior walls of the building.
The durability of the constituent materials was increased, and there was no deterioration in insulation performance.

As described above, according to the composite board for construction according to the present invention, a void for performing an air cycle can be formed in the building at the same time as the construction of the outer wall. Air cycles can be performed not only between the upper and lower ends (girders, foundations) of a building, but also from the middle, making the air cycle more comprehensive. There is no condensation and no corrosion of the constituent materials due to sufficient air cycle and insulation.
It is easy to construct because it is lightweight. It has the following characteristics.
