Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a termite prevention structure for preventing termites from entering a building.

[0002]

2. Description of the Related Art In general, underfloor structures such as floor bundles of buildings are directly placed on concrete or stone slabs, thereby causing damage by termites and erosion by mold. I have received it. Due to such damage, the floor bundle may be distorted for a certain period of time, causing the floor bundle to be distorted, causing the building to tilt or the floor to fall off.

As a method of preventing damage to termites, which is one of the causes of such aging of the bed bundle, techniques for applying or infiltrating the bed bundle with a termiticide have already been put to practical use. . However, in this method, it is difficult to infiltrate the termite-controlling agent into the inside of the bed bundle, and actually, the floor-bundle treated with the termite-controlling agent may be damaged by termites.

[0004]

Another method is as follows.
In the state where termites cannot supply water, utilizing the fact that the termites can crawl up only about 1 m from the moist ground, the floor bundle etc. provided with a flat termite prevention plate in order to lengthen the path of termites crawling Are known. However, when the flat termite prevention plate is provided in this way, there is no danger that the termites may climb over the termite prevention plate by climbing an ant path and pulling up.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a termite prevention structure which can surely prevent termites from climbing large and can be easily installed and requires no maintenance. I do.

[0006]

The present invention employs the following means to achieve the above object. That is, a means of providing a vibration sound generation source for generating a vibration sound for termite repulsion in the underfloor structure is employed.

When a part of a termite's nest is broken or a foreign enemy invades, the ant escapes and the soldier ants appear on the front and start taking an aggressive action. It is known to hit the floor and make a continuous sound.

For this sound, for example, there is no reaction of termites in the sound propagated from the loudspeaker in the air, but when the vibration from the loudspeaker is transmitted through a structure, it is 100 to 150.
There is a response at 0 Hz, and the response is strongest around 1150 Hz. The vibration sound is a signal that signals danger, and the termites have the habit of forming a group and moving downwards. Therefore, by transmitting a vibration sound similar to this vibration sound by the vibration sound source and transmitting it to the underfloor structure, the termites move downward and do not warn and climb upwards, so Termites can be prevented from invading.

Although it is possible to use an electric configuration such as a speaker or a piezoelectric element as described above as the vibration sound generating source, there is a drawback that it is expensive because an electric circuit is required. . Therefore, the configuration of the floor bundle constituting the underfloor is as follows.

That is, a grounding plate received by the foundation structure of the building, a receiving plate for receiving the heavy duty, two screw shafts respectively connected to the grounding plate and the receiving plate, and a screw on both screw shafts. A floor bundle provided with a telescopic mechanism having a buckle interposed so as to interlock and a pair of upper and lower lock nuts for fixing the screw shaft to the buckle. A thin plate is externally fitted to at least one of the screw shaft or the screw shaft between the buckle and the lower locknut, and the thin plate is sandwiched between the buckle and the locknut.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 show an embodiment in which the present invention is applied to a concrete fabric foundation. As shown in FIG. 1 (a), a metal plate 3 for transmitting vibration is fixed to the fabric foundation 1 in a strip shape. The vibration sound source 2 is disposed on the plate 3. The metal plate 3 may be provided with a folded portion 3a as shown in FIG. 1B. In this case, the termites are prevented from moving upward by the folded portion 3a, and are moved upward. Becomes more difficult.

As shown in FIG. 2, for example, a metal plate 3 for transmitting vibration is fixed to a cloth base 1 in a strip shape, and a metal square plate 4 is connected to the metal plate 3 at a corner portion. 4 is provided with a vibration sound source 2. Also in this case, the metal plate 3
It is also possible to adopt a configuration in which the folded portion 3a is provided as in the embodiment.

FIG. 3 shows an embodiment in which the present invention is applied to a bundle of floors. Figure 1
The method of installing the vibration sound source 2 and the metal plate 3 in FIG. 3 is not particularly limited, such as a method of screwing or a method of attaching with an adhesive or an adhesive tape.

With the above configuration, the vibration sound generated by the vibration sound generation source 2 is transmitted to the metal plate 3 or the floor bundle 5 for transmitting vibration, and the termites are alerted to the vibration sound and move downward. Do not climb upwards. Since termites are often active near the ground, it is desirable that the vibration sound source 2 and the metal plate 3 for transmitting vibration in FIGS. 1 to 3 be installed at a low position near the ground. However, since the active area differs depending on the type of termite, it may be installed not only at the low position near the ground as described above, but also at a position somewhat away from the ground, and at a low position near the ground and at a position somewhat away from the ground It is also possible to install them in both of them, and the installation position and the number can be arbitrarily selected.

The vibration sound generating source 2 may have an electric configuration using a speaker, a piezoelectric element, or the like, or may use a vibration generator using rotation of a motor.
When the configuration described below is adopted, the object can be achieved at relatively low cost.

Next, a floor bundle according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG.
The floor bundle shown in the perspective view of FIG. 1 includes a ground plate 11 that is received by a foundation structure of a building (a slab, a concrete fabric foundation, a solid foundation, and the like), a receiving plate 12 that receives a rough pull, and the ground plate 11 and An extension mechanism 13 including screw shafts 15 and 16 and a buckle 14 for connecting to the receiving plate 12 is provided.

The telescopic mechanism 13 includes a buckle 14 having a longitudinal axis, a pair of upper and lower screw shafts 15 and 16 which are screwed to upper and lower ends of the buckle 14 and whose screw winding directions are opposite to each other.
-A pair of upper and lower lock nuts 17 and 18 for fixing the 16 to the buckle 14 are provided. The expansion and contraction mechanism 13 makes it easy to adjust the height by rotating the buckle 14.

The screw shaft 15 and the thin plate 19 between the buckle 14 and the lock nut 17 are fitted to the outside, and are clamped by the buckle 14 and the lock nut 17. This thin plate 19
However, the vibrating sound is generated by vibrating due to the flow of air under the floor due to ventilation with the outdoors, and the vibrating sound is transmitted to the buckle 14 and the screw shaft 16, so that the termites are alerted to the vibrating sound and Move to and do not climb upwards. The thin plate 19
The shape may be any shape, size, and thickness that vibrates from the flow of air, and may be foil as long as the strength is maintained. For example, the diameter may be about 15 to 30 cm, and the thickness may be about 0.1 to 0.1. A disk shape of about 0.3 mm is appropriate.

The screw shaft 16 and the thin plate (not shown) between the buckle 14 and the lock nut 18 can be fitted to the outside, and can be clamped by the buckle 14 and the lock nut 18. Two sheets may be provided, or only one may be provided. Further, the thin plate can be attached to the buckle 14 or the like, and the installation position is not particularly limited.

With this configuration, the termites can be prevented from invading by being alerted by the vibration sound without impairing the height adjustment function of the floor bundle.

[0021]

As described above, the termite prevention structure of the present invention has
Since the vibration sound source is provided to the underfloor structure so that the vibration sound for termite repelling is transmitted, the termites are not wary of climbing above the underfloor structure, and the invasion of termites can be prevented.

In the case where a thin plate as a vibration source is attached to a floor bundle provided with an expansion / contraction mechanism, it is not necessary to use a vibration sound source having a special configuration, so that the configuration and construction are simplified, and no maintenance is required. It is.
