は行われる。Foam molding of the foamed bead base material is carried out by first heating it at a temperature of 80 to 120° C. for about 1 to 5 minutes using steam heating or the like, thereby causing primary foaming to an expansion ratio of about 10 to 80 times. The heating temperature at this time is higher than the melting point of the anti-termite agent, but since the foam bead base material is protected by a lubricant, blocking between the foam beads due to melting of the anti-termite agent is reliably prevented. Primary foaming is performed in this state.

される。To form the barrier layer 3, a large number of foamed beads 31 containing an anticide in one or both of them and an adhesive 32 are used.
A mixture of the above-mentioned materials and materials may be prepared, and this mixture may be spread so as to form a layer 1 having a certain thickness over the entire surface of the subfloor ground surface 2a. As the predetermined curing time elapses, the foamed beads 31
The adhesive 32 is applied to the gap between the foam beads 31.
are integrated in a filled state, thereby forming a barrier M3 that isolates between the underfloor ground surface 2a and the underfloor space 2b.

２などの食害を防止することができる。Even if a termite tries to break through the barrier layer 3 from the subfloor ground surface 2a, the termite will destroy the foam beads 31 and the adhesive 3.
They are repelled by the anticide contained in one or both of 2 and 2, and cannot penetrate the barrier layer 3. This allows the upper platform 41 and pillars 4 on the cloth foundation 1 in wooden buildings to
It is possible to prevent feeding damage such as 2.

Furthermore, heating heat inside the building can be prevented from escaping to the underfloor ground surface 2a via the underfloor space 2b.

調べることにより行った。In the comparative test, as shown in Fig. 3, bait trees 6 and sand 7 were placed in three containers 5 with a diameter of 80 m+, and 300 worker ants of the Japanese domestic termite were previously reared in these containers. A barrier layer test piece 8 was formed by placing the sample above the ground inside the container so that its peripheral edge was in contact with the inner wall of the container, and a bait tree 6 was placed on the top surface of this barrier layer test piece 8. This test was carried out by leaving this condition for 2 months and examining whether or not the house termites could penetrate upward through the barrier layer test piece 8.

い。According to the above test results in Table 1, in sample C, in which neither the foam beads nor the adhesive contained an anti-termiticide, termites were able to penetrate the shells 1, and even if this was used as an insulating layer on the subfloor surface, it caused feeding damage. cannot play a preventive role. On the other hand, in samples A and B according to the present invention, even after 6 months, the anti-termite underfloor structure of claim 1 of the present invention shows that the ground surface of the floor F is A barrier layer is formed that covers the entire surface, and termite preventive agents are mixed in one or both of the foam beads and adhesive that make up this barrier layer, so termites cannot penetrate the barrier layer. This makes it possible to reliably prevent termite damage, and since the termite control agent does not leak outside, it does not pollute the environment.

This work can be easily performed without being affected by the shape of the subfloor ground surface, which can contribute to reducing construction costs.

法。[Claims] 1. A barrier layer is formed on the upper surface of the subfloor ground surface surrounded by the fabric foundation so as to be in contact with the inner circumferential surface of the wall of the fabric foundation and to cover the entire surface of the subfloor ground surface. This barrier layer is formed by a large number of foamed beads made of synthetic resin and an adhesive that adheres the foamed beads to each other and fills the gaps between the foamed beads. An ant-proof underfloor structure characterized in that one or both of them contain an anti-termite agent. 2. Add an anti-termite agent to either or both of the foamed beads made of synthetic resin and the adhesive, mix a large number of these foamed beads and the adhesive, and apply this mixture to the area surrounded by the fabric foundation. A method for constructing a termite-proof subfloor structure, which comprises forming a barrier layer on the upper surface of the subfloor by spraying the material on the subfloor so that the entire surface of the subfloor is shielded.
