[Industrial Application Field] This invention is a plastic foam board that can be used for flooring,
This invention relates to a heat insulating material for wooden buildings that is placed on the back side of decorative panels on walls and ceilings to provide insulation between indoors and outdoors. [Prior Art] In order to achieve thermal insulation between indoors and outdoors, it has been adopted to arrange a plastic foam board as a heat insulating material on the back side of a decorative board. Conventionally, such a heat insulating material, for example, in the case of a floor, is produced in advance at a factory from plastic foam boards cut to fit the width between the floor joists, which are reinforcing structural members. This will be transported to the site and used for construction. The important thing about this type of insulation is to eliminate the gaps between the decorative panels and the interior panels to prevent cold air from passing through. To do this, a support material is placed on the outdoor side of the insulation material and adjusted so that the indoor side of the insulation material and the indoor side of the structural material are flush with each other, and the decorative board is placed so that it is in close contact with these indoor sides. The gap between the decorative boards was eliminated by installing insulation material. [Problems to be solved by this invention] If the insulation material is pre-cut at the factory to fit the width between the structural members as described above, the number of foam boards used will be extremely large, making inventory management extremely difficult. becomes. In addition, due to its bulk, it requires a lot of effort to pack and unpack, and also requires a lot of effort to transport and bring in. In addition, when adjusting the insulation material and the structural material flush using the support material as described above, it is necessary to procure the material for the insulation material and the support material separately and cut it to the appropriate size. This is extremely troublesome work. This invention aims to provide a heat insulating material for wooden buildings that is easy to manage inventory, requires little effort in packing and unpacking, requires little effort in transportation and loading, and is also easy to install on floors, etc. purpose. [Means for Solving the Problems] The insulation material for wooden buildings according to this invention is provided by adding the plastic foam board to the surface of the plastic foam board, and adding the plastic foam board to the insulation part of the width between the structural members, and the outdoor side of this insulation part. a slit that is partitioned into a receiving part that is sufficiently narrower than the heat insulating part and has a sufficient depth to allow the heat insulating part and the receiving part to be easily separated by hand for being disposed as a receiving material in the slit; is formed parallel to the long side of the board. Separation can be easily done by bending the foam board using slits. [Example] This invention will be described in detail below based on an example shown in the drawings. In the figure, A is a heat insulating material for wooden buildings according to this invention, which is formed from a plastic foam board 1 which is a rectangular plate. plastic foam board 1
As the material, bead foamed polystyrene foam board, extruded foamed polystyrene foam board, polyethylene foam board, etc. can be adopted. A plurality of groove-shaped slits 2 are formed on the surface of the plastic foam board 1 in parallel with the long sides of the plastic foam board 1. This slit 2 is formed by a saw, a hot wire, etc.
It has a width of about 1 mm and is deep enough to be easily separated by hand, that is, deep enough to reach the middle part of the thickness of the plastic foam board 1. A portion of the foam board 1 partitioned by the slit 2 serves as a heat insulating section 3 disposed between structural members 5, which will be described later. The other part partitioned off by the slit 2 is a receiving material 4 used as a receiving material 6. The receiving part 4 is formed to be sufficiently narrower than the heat insulating part 3. Figures 1 to 3 show a heat insulating material A used for a floor in a Western-style room, in which three heat insulating parts 3 and one receiving part 4 are separated by a slit 2. In the case of a floor, the heat insulating part 3 is placed between the joists 5, 5, which are auxiliary structural members.
The width a is the same as the width a' between the joists 5 and 5. Further, the width a of the receiving portion is determined by the height h of one side of the joist 5 and the thickness t of the foam board 1. That is, the following equation holds true among the width b of the receiving portion 4, the height h of the joist 5, and the thickness t of the foam board 1. h=t+b Therefore, the width b of the receiving portion 4 is determined by the following formula. b = h - t For example, if the width h of one side of the joist 5 is 45 mm,
When the thickness t of the foam board 1 is 20 mm, the receiving part 4
The width b is 25 mm. Required height h for joist 5
There are several types of wood, and from experience, square timbers with a side height of 40 mm and 45 mm are widely used. Further, the foam board 1 is available in a plurality of types with a required thickness t depending on the region and place of use; for example, foam boards 1 of 20 mm, 25 mm, and 30 mm are used. When using joists 5 of 40 mm and 45 mm, and using each of the three types of foam boards 1 described above, the width b of the receiving portion 4 is as shown in the table below.

This invention has the above configuration and can obtain the following effects. Since the insulation material is made of foam board with a negative number of insulation parts and is transported to the site and separated at the slit, the number of foam boards is reduced, inventory management is easier, and packaging and unpacking are easier. This reduces the amount of effort required or, in some cases, eliminates the need for transportation, and the labor involved in transporting and importing the product is also reduced. Since it has a part of the receiving part that is placed on the outdoor side of the insulation part as a receiving material and makes the insulation part and the indoor side of the structural material flush with each other, it can be used by separating it with a slit as a boundary, without having to purchase it separately. This makes it extremely easy to install the heat insulating material.
