[Detailed description of the invention] The invention is inexpensive and easy to construct, and
In addition, the present invention relates to a floor insulation structure that has sufficient support strength and allows the use of floor boards and insulation materials in combination.

Conventionally, as shown in Fig. 1, a floor insulation structure consists of quadrangular prism-shaped floor forming support members a arranged approximately horizontally at intervals, and for example, a heat insulating material c is installed between the joists using support fittings b. Support member a
A waste board d is placed on the top surface, and a tatami mat e or cushion floor is further laid on top of it. In this floor insulation structure, since the supporting metal fittings b exist between the supporting member a and the heat insulating material c, the gap formed by these supporting metal fittings b and the supporting member a
Insulating material c and waste board d formed by uneven surfaces
The insulation effect may be lost through the space between the
Due to the existence of these, there is a problem of increased labor and material costs for laying each layer one after another.

The present invention provides a floor insulation structure that is inexpensive, easy to construct, has sufficient support strength, and allows the use of floor scrapboard and insulation material in combination. This is what I am trying to do.

Details of the floor insulation structure according to the present invention will be explained based on FIG. 2. In the present invention, the support members 1 for forming a floor in the form of quadrangular prisms arranged in a substantially horizontal direction at intervals, for example, the heat insulating member 2 installed between the joists, have an L-shaped step for receiving the support members 1 as shown in the figure. The portions 3 are provided opposite to each other at the corners of both ends of the low-foaming hard synthetic resin plate, and slits 4 having an appropriate opening width are provided between the L-shaped step portions 3, 3 in parallel with the support member 1. It is set up. And this insulation member 2
By fitting between the support members 1 as shown in the figure, a floor insulation structure is formed. That is, the support members 1 are formed by cutting out the corner portions of both ends of a low-foaming hard synthetic resin plate so as to face each other between the support members 1 for forming a floor in the shape of square columns arranged in a substantially horizontal direction at intervals. L-shaped step portions 3 for receiving the L-shaped step portions 3 are protruded from both sides as mounting pieces and are opposed to each other, and are fitted between the supporting members 1 so as to be located at least on the distal end side of the mounting pieces between both L-shaped step portions 3. This L in the part
A heat insulating member 2 provided with slits 4 having an appropriate number of opening widths in the longitudinal direction along the stepped portion 3 is attached to the support member 1 by positioning this mounting piece on the upper surface of the support member 1.
This L-shaped stepped portion 3 is locked to the corner of the support member 1, and the portion located between both L-shaped stepped portions 3 is fitted into the support member 1 by contracting the opening width of the slit 4 and deforming it under pressure. This creates a floor insulation structure. The low-foaming rigid synthetic resin board that is the heat insulating member 2 is made of a low-foaming polystyrene board, a foaming ABS resin board, etc., and L-shaped stepped portions 3 are formed at both ends. As shown by the dashed line in the figure, the vertical wall surface 5 of No. 3 has elasticity when fitted between the supporting members 1 as an outwardly facing inclined surface 6, i.e., the support when the vertical wall surface 5 is inserted between the supporting members 1. In addition to serving as a means to increase elasticity, slits 4 are provided between both L-shaped step portions 3, 3. The slits 4 may be formed evenly between both L-shaped step portions 3, 3 as shown in the figure.
It is also free to form it so that it is biased toward one side or distributed on both sides. In addition, by providing the number of slits with a total width that can absorb the sloped portion of the vertical wall surface 5 of the L-shaped step 3, the balance between the slope 6 of the vertical wall surface 5 and these slits 4 is utilized. can do. The foaming ratio of this low-foaming hard synthetic resin board is about 5 to 20 times for foamed polystyrene boards, and about 10 to 25 times for foamed ABS resin boards.

Thus, such a heat insulating member 2 is attached to the support member 1,
In the case of the floor insulation structure installed internally in the room 1, the slit 4 is formed between the L-shaped step parts 3, 3, and the insulation member 2 itself is made of a low-foaming hard synthetic resin board, so that it has a Due to its elastic properties, it is easy and quick to install it between the supporting members 1, 1, and even if the surface of the supporting members 1 is uneven, the mutual adhesion is maintained, and furthermore, the entire structure has low foaming. Because of its strength, the upper surface part, that is, the part placed on the surface of the support member 1, functions as a substitute for the waste board when forming the floor, and it becomes a state in which the waste board and the heat insulating material are used at the same time. be. In addition, since the heat insulating member 2 is made of a single material in this way,
Prevents water vapor from entering the room from under the floor,
It also has a high heat insulating effect, making it possible to use the waste board and heat insulating material together.

In the floor insulation structure according to the present invention as described above, the L for receiving the support member for floor formation is
L-shaped stepped portions are formed at the corners of both ends of the low-foaming hard synthetic resin board, and a heat insulating member with slits provided between the L-shaped stepped portions is spaced between support members disposed approximately horizontally. Because it is made by inserting
This formation is easy, and the support strength of the heat insulating member to the supporting member after being formed is high.
Moreover, the waste board and the heat insulating material are used together by using a single heat insulating member, and it is possible to lay tatami mats, cushion floors, etc. directly on the surface of these members.
