Description

The present invention relates to an insect repellent measure technique for building foundations.

Ventilation is essential for housing foundations. Poor ventilation of the foundation of a house can cause moisture to build up under the floor, causing mold and rotting wood. Therefore, ventilation openings (openings) of, for example, about 200 mm × 400 mm are often provided on the side surface of the building foundation.

However, if a ventilation port is provided in the building foundation, the strength of the building foundation may be reduced. In addition, the number of ventilation openings is limited from the viewpoint of ensuring strength, and moisture tends to be trapped in a range far from the ventilation openings. In addition, small animals may invade through the ventilation openings.

Therefore, a foundation packing (also referred to as a ventilation pedestal) has been proposed in place of the ventilation port (Patent Document 1). The foundation packing is a resin member provided with a plurality of holes for underfloor ventilation, and is interposed between the building foundation and the foundation.

The foundation packing is provided so as to surround substantially the entire outer circumference of the building foundation, and enables ventilation from all directions to the underfloor. In addition, a large number of ventilation holes ensure the amount of ventilation. On the other hand, there is no defect in the building foundation and there is no risk of strength decrease.

Further, one vent is, for example, about 20 mm × 10 mm (or less), and there is no possibility that a small animal such as a mouse invades.

Japanese Unexamined Patent Publication No. 2012-184620

The size of the vents of the foundation packing is relatively small, and although it can prevent the invasion of small animals, it cannot prevent the invasion of insects such as ants.

In Patent Document 1, the foundation packing and the like are treated with chemicals, and a sheet or plate treated with chemicals is installed on the back side of the drain to expect an anti-termite effect.

The above-mentioned drug treatment does not immediately lead to health damage if it is used properly, but when used in combination with a physical anti-termite effect, a synergistic effect can be expected and the drug usage fee can be reduced.

~ Building foundation structural composition ~
FIG. 1 is a schematic configuration diagram of a building foundation structure and a bug-returning structure. 2 to 4 are views for explaining the procedure for attaching the insect repellent structure according to the present embodiment.

First, a general building foundation structure will be described. The building foundation structure is mainly composed of a building foundation 1, a foundation packing 2, a base 3, a wall portion 4, an exterior material 5, and a draining plate 6.

The building foundation 1 is a member made of reinforced concrete for supporting a house, and includes a slab forming the bottom surface and a rising portion rising from the bottom surface. The building foundation 1 includes a solid foundation and a cloth foundation, but any of them may be used in the present embodiment.

The foundation packing 2 is a resin member interposed between the building foundation 1 and the foundation 3. The foundation packing 2 is provided over substantially the entire length of the building foundation 1 located on the outer periphery of the house.

The features of the foundation packing 2 when viewed in a substantially plan view will be described. Two long members are connected in the short direction via a continuous portion. The foundation packing is arranged so that the elongated direction is along the longitudinal direction of the building foundation 1 (and the surfaces coincide with each other) (see FIG. 2). With the above arrangement, a space for inserting an anchor bolt (not shown) erected from the building foundation 1 is formed between the two long members.

The features of the foundation packing 2 when viewed from a substantially elevation will be described. The foundation packing 3 is formed with a thickness of, for example, about 20 mm. A plurality of ventilation holes 21 continuous in the elongated direction are provided. A large number of ventilation holes 21 enable ventilation between the outside and the underfloor space.

The ventilation hole 21 is a space formed by the upper bottom portion 22 of the foundation packing and the partition walls 24 and 24 continuous with the lower bottom portion 23 of the foundation packing (see FIG. 8).

The base 3 is often wood installed on the foundation packing 2. The foundation 3 is fixed to the building foundation 1 by anchor bolts (not shown). A floor material (not shown), which is a flat plate member extending in the horizontal direction, is installed on the base 3.

The wall portion 4 is a member that is erected in the vertical direction and is installed on the floor material. The exterior material 5 is provided on the wall portion 4 via a gap. The exterior material 5 is a plate-shaped member that is erected in the vertical direction and covers the outside of the house.

The draining plate 6 is a metal plate-shaped member attached to the side surface of the base 3 by a screw nail. The draining plate 6 is arranged so as to cover the upper end of the building foundation 1, the foundation packing 2, and the side portion of the foundation 3, and protects these members from rainwater.

~ Insect repellent structure ~
Next, the insect return structure will be described. The insect repellent structure is composed of a foundation packing 2, an insect repellent plate 7, and a mounting jig 8. In principle, the insect repellent structure is provided on almost all foundation packings 2 (see FIG. 4).

FIG. 5 is a block diagram of the insect return plate 7. 5A is a perspective view and FIG. 5B is a cross-sectional view. Note that FIG. 5C is a cross-sectional view of a modified example (described later).

The insect repellent plate 7 includes a mounting portion 71, a building foundation contact portion 72, and an insect repellent portion 73.

The attachment portion 71 has a hook shape, and attaches the insect return plate 7 to the foundation packing 2 (indirectly) via the attachment jig 8. In the example shown in the figure (FIG. 1 or 5), the hook of the mounting jig 8 and the hook of the mounting portion 71 are engaged with each other.

The building foundation contact portion 72 is a flat plate-shaped member that comes into contact with the side surface of the building foundation 1. In the illustrated example, it is continuous with the mounting portion 71 via the connecting portion 74.

The insect return portion 73 is a flat plate-shaped member extending diagonally downward from the building foundation contact portion 72 in the building foundation contact state. The angle formed by the plane formed by the building foundation contact portion 72 and the plane formed by the insect repellent portion 73 is preferably about 15 to 45 degrees. Further, about 20 to 40 degrees (around 30 degrees) is more preferable. With this predetermined angle, the insects that come up from the ground along the building foundation 1 are repelled.

The insect return plate 7 has a length substantially equal to that of the foundation packing 2 in the long direction.

6 and 7 are block diagrams of the mounting jig 8. Some variations are illustrated.

In FIG. 6, the mounting jig 8 includes a mounting portion 81, a building foundation contact portion 82, and a vent hole insertion portion 83.

In FIGS. 6A to 6D, the mounting portion 81 and the building foundation contact portion 82 are substantially common. That is, the mounting portion 81 has a hook shape, and the hook of the mounting portion 81 and the hook of the mounting portion 71 engage with each other to attach the insect repellent plate 7 to the foundation packing 2. Further, the building foundation contact portion 82 is the back surface of the mounting portion 81 and is in contact with the side surface of the building foundation 1.

In FIG. 6A, the cross-sectional shape of the ventilation hole insertion portion 83 substantially corresponds to the shape of the inside of the ventilation hole 21. Further, a locking portion 84 that is locked to the end surface of the upper bottom portion 22 of the foundation packing is provided.

The ventilation hole insertion portion 83 is fitted into the ventilation hole 21, the locking portion 84 is locked to the end surface of the upper bottom portion 22 of the foundation packing, and the building foundation contact portion 82 is brought into contact with the side surface of the building foundation 1. The mounting jig 8 is securely mounted on the foundation packing 2.

In FIG. 6B, the cross-sectional shape of the vent hole insertion portion 83 substantially corresponds to the lower half of the inner empty shape of the vent hole 21. Further, an independent restraint member 85 is provided. The cross-sectional shape of the restraint member 85 substantially corresponds to the upper half of the empty shape of the ventilation hole 21. The restraining member 85 includes a locking portion 84 that is locked to the end surface of the upper bottom portion 22 of the foundation packing, and a removing claw 86 that facilitates removal.

The ventilation hole insertion portion 83 is inserted into the ventilation hole 21, the building foundation contact portion 82 is brought into contact with the side surface of the building foundation 1, and the restraint member 85 is fitted into the ventilation hole 21 to ensure mounting. The jig 8 is attached to the foundation packing 2 (see FIG. 3). Since the mounting jig 8 is composed of two members, it is easy to insert and remove.

In FIG. 6C, the cross-sectional shape of the ventilation hole insertion portion 83 is circular, and the length of the ventilation hole insertion portion 83 substantially corresponds to the depth of the ventilation hole 21. Further, the foundation packing partition walls 24 are provided with locking portions 84, 84 to be locked to the end faces (front and back). The cross-sectional shape of the locking portions 84, 84 is smaller than the shape of the ventilation hole 21.

The ventilation hole insertion portion 83 is inserted into the ventilation hole 21 by rotating the mounting member by approximately 90 degrees and inserting the locking portion 84 on the rear side of the drawing into the ventilation hole 21. Further, when the mounting member is rotated in the reverse direction by approximately 90 degrees, the building foundation contact portion 82 is brought into contact with the side surface of the building foundation 1, and the locking portions 84 and 84 are locked to the end surfaces (front and back) of the foundation packing partition wall 24. As a result, the mounting jig 8 is securely mounted on the foundation packing 2.

In FIG. 6D, the ventilation hole insertion portions 83, 83 are two substantially trapezoidal flat plates facing each other. The back side of the figure is the short side of the trapezoid, and the front side of the figure is the long side of the trapezoid. The distance between the two flat plates substantially corresponds to the distance between the foundation packing partition walls 24 and 24.

When the vent hole insertion portion 83 is inserted into the vent hole 21, the two flat plates act as leaf springs and press the partition walls 24 and 24, respectively. Further, the building foundation contact portion 82 is brought into contact with the side surface of the building foundation 1, so that the mounting jig 8 is reliably mounted on the foundation packing 2. Due to its substantially trapezoidal shape, it is easy to insert and remove.

In FIG. 7, the mounting jig 8 includes a mounting portion 81, a building foundation contact portion 82, a locking portion 84, and partition wall holding portions 87 and 87. 7A-C show one embodiment from multiple directions.

In FIG. 7, the mounting portion 81, the building foundation contact portion 82, and the locking portion 84 are substantially the same as those in FIG.

The partition wall holding portions 87, 87 are two opposing members. It bites inward slightly so that it can be easily pinched. The distance between the two members corresponds approximately to the wall thickness of the foundation packing partition wall 24. Further, a locking portion 84 to be locked to the end face of the foundation packing partition wall 24 is provided.

When the mounting jig 8 is pushed so that the partition wall holding portions 87, 87 fit into the partition wall 24, the partition wall holding portions 87, 87 act as springs and sandwich the partition wall 24. Further, the building foundation contact portion 82 is brought into contact with the side surface of the building foundation 1, and the locking portion 84 is locked to the end surface of the foundation packing partition wall 24, so that the mounting jig 8 is securely attached to the foundation packing 2.

Compared with the mounting jig 8 having the ventilation hole insertion portion 83, the mounting jig 8 having the partition wall holding portions 87, 87 is advantageous in that the ventilation amount can be secured.

The chamfer insertion portion 88 shown in FIG. 7B will be described later.

~ Installation procedure ~
Returning to FIGS. 2 to 4, the procedure for attaching the insect repellent structure will be described.

The foundation packing 2 is arranged so that the long direction of the foundation packing 2 is along the longitudinal direction of the building foundation 1 and the end surface of the foundation packing 2 and the side surface of the building foundation 1 are substantially the same plane (see FIG. 2).

The mounting jig 8 is attached to the foundation packing 2 by inserting it into the ventilation hole 21 of the foundation packing 2 and locking it, or by sandwiching it between the partition walls 24 (see FIG. 3).

By engaging the mounting portion 71 and the mounting portion 81, the insect repellent plate 7 is attached to the foundation packing 2 via the mounting jig 8. At this time, make sure that the building foundation contact portion 72 is in contact with the side surface of the building foundation 1 (see FIG. 4).

~ Auxiliary function ~
The following auxiliary functions may be added so that the insect return plate 7 is more reliably attached to the foundation packing 2.

The mounting jig 8 includes a chamfer insertion portion 88 (see FIG. 7B). FIG. 8 is a cross-sectional view showing a mounting state of the mounting jig.

In the foundation packing 2, the corner portion formed by the lower surface of the foundation packing and the end surface is chamfered. In addition, it may be chamfered at the corner of the top of the building foundation 1. Therefore, a chamfered space is formed by the top of the building foundation and the lower surface of the foundation packing.

The chamfer insertion portion 88 extends substantially at a right angle from the building foundation contact portion 82, is inserted into the chamfer space, and is locked. When the building foundation contact portion 82 is brought into contact with the side surface of the building foundation 1, the mounting jig 8 is restrained in the horizontal direction, and the mounting jig 8 is restrained in the vertical direction by the chamfering insertion portion 88. ..

As a result, the mounting jig 8 is securely mounted on the foundation packing 2. As a result, the insect return plate 7 can be attached to the foundation packing 2 more reliably.

Returning to FIG. 5C, the auxiliary function of the insect return plate 7 will be described.

In FIG. 5B, the building foundation contact portion 72 substantially coincides with the assumed surface of the building foundation contact in the unattached state (no inclination angle).

On the other hand, in FIG. 5C, the building foundation contact portion 72 is inclined by a predetermined angle with respect to the assumed surface of the building foundation contact so that the lower end is on the building foundation side in the unattached state.

The inclination angle is preferably about 5 to 30 degrees. Further, about 10 to 25 degrees (around 20 degrees) is more preferable.

In FIG. 5C, when the insect return plate 7 is attached so that the building foundation contact portion 72 is surely contacted with the side surface of the building foundation 1, the connecting portion 74 acts as a leaf spring and the building foundation contact portion 72. Is pressed against the side surface of the building foundation 1. In particular, a strong pressing force is generated at the lower end of the building foundation contact portion 72.

As a result, the insect return plate 7 can be more reliably attached to the foundation packing 2, and insects can be prevented from invading other than the insect return portion 73.

~ Modification example ~
The invention of the present application is not limited to the above embodiment, and various modifications can be made within the scope of the technical idea.

As an example of the deformation, a deformation example (deformation example 1) of the mounting structure of the mounting portion 71 of the insect return plate 7 and the mounting portion 81 of the mounting jig 8 will be described. FIG. 9 is an exploded configuration diagram of the modified example 1, and FIG. 10 is a diagram showing a mounting state of the modified example 1.

The mounting portion 71 of the insect return plate 7 is a hole continuous in the elongated direction. The mounting portion 81 of the mounting jig 8 includes a shaft portion and a locking portion. The shaft portion is erected from the opposite side surface of the building foundation contact portion 82. The locking portion is a dome-shaped member provided on the head of the shaft portion.

The diameter of the mounting portion 81 shaft portion is slightly smaller than that of the mounting portion 71 (hole), and the diameter of the mounting portion 81 locking portion is the same as or slightly larger than that of the mounting portion 71. The length of the mounting portion 81 shaft portion substantially corresponds to the depth of the mounting portion 71 (hole).

The mounting portion 81 inserts the mounting portion 71, and the mounting portion 81 locking portion is locked around the hole. As a result, the hook of the mounting jig 8 and the hook of the mounting portion 71 are fitted.

As a result, the insect return plate 7 is attached to the foundation packing 2 via the attachment jig 8.

The insect return plate in the embodiment is extruded, but the insect return plate in the first modification can be manufactured by injection molding.

Another example of deformation (modification example 2) will be described. FIG. 11 is a configuration diagram of the modified example 2.

In the above embodiment, the insect repellent plate 7 and the mounting jig 8 have different configurations and are integrated by the mounting structure of the mounting portion 71 and the mounting portion 81, but the insect repellent plate 7 and the mounting jig 8 are mounted as in the second modification. The jig 8 may be integrally molded. The insect return plate 7 is directly attached to the foundation packing 2.

The integral structure in the second modification can be manufactured by injection molding.

~effect~
The inventor of the present application has focused on the fact that the foundation packing is superior to the conventional ventilation port in various respects. Then, we planned to further improve the insect repellent effect.

Specifically, by observing the shape of the foundation packing, the insect repellent structure was realized with a simple structure while using the existing foundation packing as it is.

Since it has a simple structure, it is housed in the space formed by the drainage 6. The function of the drain 6 is not impaired. Further, from a normal viewpoint, the insect repellent structure is hidden by the drainage 6, so that the aesthetic appearance is not significantly impaired. Since it has a simple structure, it can be easily replaced over time.

Therefore, the invention of the present application is extremely practical.

In the present invention, a synergistic insect repellent effect can be expected when used in combination with chemical treatment. In addition, the drug usage fee can be reduced.
