The present invention relates to a roof base plate. Conventionally, for example, the base structure of a roof has been to fix roofing boards on rafters and to lay asphalt felt on top of them. For this roof base, the roofing boards and asphalt felt had to be installed separately in that order. As a result, work efficiency is poor,
Costs were rising. Furthermore, the above-mentioned base has insulation, waterproof, moisture control, soundproofing,
and had the disadvantage of lacking cushioning properties. In order to eliminate these drawbacks, the present invention has developed a sheathing insulation board that has soundproofing, heat-insulating properties, and humidity control properties that are effective in preventing condensation, and a lightweight synthetic resin foam that has excellent heat-insulating, waterproof, and cushioning properties. A reinforcing material and a reinforcing sheet, which is useful for improving sound absorption through membrane vibration and transmission through the through holes, are interposed in between, and these constituent materials are self-adhesive when forming a synthetic resin foam. The present invention proposes a roof base plate that is fixed together by utilizing its properties and has the above-mentioned properties in a single member, which greatly improves workability and work efficiency. The roof base plate (hereinafter simply referred to as base plate) according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing the base plate, in which a reinforcing sheet 2 is integrated between a sheathing insulation board 1 (hereinafter simply referred to as a board) and a synthetic resin foam 3 (hereinafter simply referred to as a foam). A back material 4 is integrally fixed to the back surface of the form 3. To explain further, the board 1 mainly consists of heat insulating materials, sound absorbing materials, waterproof materials,
It functions as a humidity control material and also provides rigidity to the base plate. As a specific example, the plate thickness is about 7 to 15 mm, the density is 400 kg/m 3 , and the size is 900 mm.
~1800mm. In addition, the reinforcing sheet 2 mainly strengthens the bending strength and tensile strength of the base plate, and the reinforcing sheet 2 of the board 1 when forming the form 3.
A part of the foam raw material is on the surface that is in contact with board 1.
Controlled impregnation of only a part of the surface layer of
This is to prevent the reaction foaming of the raw material itself from being inhibited, and to significantly improve sound absorption through membrane vibration and transmission through the through holes 2a. Its structure is as shown in Figure 2, with a plate thickness of 0.05 to 0.1 mm.
The sheet-like material is made of a type of kraft paper laminated with a synthetic resin plate, a thin metal plate, and an aluminum foil, and the through holes 2a are perforated with a coarse distribution from the outer edge toward the center. It was established. The reason why the through holes 2a are distributed as described above is to ensure that the board 1 and the form 3 are strongly adhered to each other at the periphery, thereby further strengthening the integration. Furthermore, the foam 3 not only provides heat insulation and cushioning properties to the base plate, but also functions as an adhesive to bond the board 1 and reinforcing sheet 2 together. It is made easy to do. The materials are polyurethane foam, polyisocyanurate foam, phenol foam, and polyurea foam, and the thickness is about 5 to 50 mm and the density is 20 to 60 kg/
m 3 , thermal conductivity is approximately 0.022 to 0.05kcal/m・h・℃
And, it is made of a closed cell foam structure. 4 is the back material, which functions as a mold release agent during foam formation and has mechanical strength (breaking strength of about 50 kg/ m2 or more), that is, the strength of the front and back materials in a composite structure is the core material (form 3). This is because the strength of the base plate is affected more than the strength of the base plate. In addition, the back material 4 is waterproof,
It has at least one function of heat reflection, and is intended to suppress corrosion of rafters and heat radiation from indoors to outdoors. An example of the backing material 4 is a laminated one or more of asphalt felt, felt, kraft paper, metal foil, and asbestos paper, or a sheet-like material laminated with nonwoven fabric or net-like material. It is something. Next, to briefly explain the manufacturing method of the base plate according to the present invention, the molded materials are faced to each other with a predetermined interval, for example, a gap of 30 mm, on top of the concave cross section, and the manufacturing method is approximately 30 m/min.
Assume that it moves in a constant direction at a speed of Therefore, board 1 (thickness 12 mm, density 400 Kg/m 3 ) was laid on the lower mold,
A reinforcing sheet (lass material) 2 is laid on top of this, and
Polyurethane foam raw material, which is the raw material for Form 3, is evenly dispersed, and on top of it, polyethylene laminated kraft paper (polyethylene 20 microns on one side, kraft paper 170 g/m 2 ) is used as the backing material 4. The untreated side is used as the raw material for Form 3. The materials are laminated toward the surface, then fed into a cure oven, and sent out from the outlet as a base plate with a thickness of 30 mm. At this time, the foam 3 was impregnated to 1/3 of the thickness of the board 1. The weight of this base plate is 4.9Kg/
m 2 , bending strength is 50Kg/cm 2 , heat transmission coefficient is
It was 0.51 kcal/m 2・h・℃. In addition, even when 4000 kg/m 2 was applied, the cushioning property only sagged by about 0.15 mm, and when it was removed, the current condition was restored. Furthermore, the moisture control properties are more than double that of straw, preventing the occurrence of dew condensation, and the composite board is integrated with the board 1, reinforcing sheet 2, foam 3, and backing material 4. The bending strength was 32.5Kg/ mm2 , while the composite board of board 1, form 3, and backing material 4 had a bending strength of 11.5Kg/ mm2 , and the mechanical strength was greatly improved due to the layered structure. . For this reason, when constructing the base board, there is no need for a field board, and the base board has sufficient strength even if it is laid directly on top of the rafters. That is, by laying the base plate on the rafters, it is possible to form a roof base that has heat insulating properties, humidity control properties, and sound absorbing properties, and it is possible to form the roof base easily and efficiently. Furthermore, the pull-out resistance of the nail at the edge of the base plate is approximately 30 kg, and this edge (approximately 10 to 20 kg)
The specific gravity of the width part (mm) was 0.5 to 0.8. Moreover, the compressive strength of that part was approximately 4.5Kg/cm 2 . Therefore, the base plate can be reliably fixed on the rafter, and since the connection portion between the base plates is also firmly fixed, it is possible to prevent the base plate from falling off from the connection portion. Here, the sound absorption property was measured by the reverberation room method sound absorption coefficient. As a result, the values shown in the table below were obtained. In addition,
As an example, a composite plate manufactured by the above method was used, and as a comparative example, a composite plate of the example without the reinforcing sheet 2 was used.

The foam 3 containing short fibers can also be integrally formed on the board 1. Furthermore, it can also be used as a base plate for exterior wall structures. As mentioned above, according to the base plate according to the present invention,
The base plate has heat insulating, waterproof, moisture control, and soundproofing properties, has sufficient strength, and is lightweight and easy to process. Furthermore, since the base plate has cushioning properties, there is an advantage that deformation of the roofing material due to snow accumulation can be kept within elastic deformation. Furthermore, since the base board has high bending strength and mechanical strength, the roof base can be formed without using a sheathing board. On top of that,
Because the nails have strong pull-out strength, the base plate can be securely fixed to the rafters and will not fall off.
