Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a corrosion-preventing board for building foundations used to prevent corrosion of building foundations.

(b) Conventional technology and problems to be solved by the present invention Conventionally, foundation trees used in buildings were generally fixed to the top of the concrete foundation with bolts, and most of the weight of the house was supported by this foundation tree. However, since this foundation tree is directly attached to the concrete foundation, the foundation tree installed on the foundation is also easily affected by moisture due to the property of concrete that easily absorbs moisture, so it may not be possible for a short period of time. It could not be expected to support the house without distortion over a long period of time, as it would be subject to corrosion and attack by pests.

The present invention allows the base wood to be used for a long period of time without being affected by moisture or being attacked by pests.

(c) Means for solving the problem In view of the above-mentioned drawbacks of conventional buildings, this invention prevents the contact between the concrete foundation and the foundation wood so that moisture absorbed by the concrete foundation can be absorbed by the foundation. In order to prevent it from penetrating into the wood, a non-hygroscopic synthetic resin strip is sandwiched between the concrete foundation and the foundation wood to prevent corrosion of the foundation wood and prevent it from being attacked by pests such as termites. In addition to incorporating an insect repellent into the material when molding the synthetic resin board to make it effective as an insect repellent, we also added a synthetic resin band board between the concrete foundation and the foundation wood. To make it easier, a hook-shaped bent part is provided on the outer edge of the synthetic resin strip plate, and cut-outs for joining are provided in opposite directions on the inner edge. By adjusting the length of the connection, the strip plate can be easily and tightly fitted onto the top surface of the concrete foundation regardless of its thickness, making it easier to sandwich the strip plate between the concrete foundation and the foundation wood. This is what I did.

(d) Embodiment and operation An example of the implementation of the present invention will be explained below with reference to the drawings.

In the figure, 1 and 1' are a pair of left and right synthetic resin belt-like plates impregnated with insect repellent, with hook-shaped bent parts 2 and 2' on the outer edge, and attached to the inner edge in opposite directions. Cutouts 3, 3' are provided for adjusting the degree.

The degree of connection of the notches 3, 3' can be freely adjusted to length or short according to the thickness of the concrete foundation A, which facilitates the work. That is, if the notches 3, 3' are not provided, it is not possible to easily attach the strip plate to the thickness of the concrete foundation.

B is a foundation wood made by stacking synthetic resin strip plates 1 and 1' on top of the concrete foundation A. C is a bolt that protrudes from the concrete foundation A and passes through the bolt receiving hole 4 provided in the strip plates 1, 1' and the bolt receiving hole 5 provided in the foundation tree B, and the screw 6 is attached to the protruding end. It is screwed on.

Since the present invention is constructed as described above, in order to use the synthetic resin band plates 1, 1' sandwiched between the concrete foundation A and the foundation wood B, it is necessary to One strip plate 1, 1'
The hook-shaped bent part 2 of the other band-shaped plate is aligned with the inner wall, and the hook-shaped bent part 2' of the other band-shaped plate is aligned with the inner wall, and the degree of connection of the notches 3, 3' provided on the inner edge of the band-shaped plate is adjusted. Place the strip plate on the concrete foundation while matching the thickness of foundation A, then insert the strip plate between concrete foundation A and foundation tree B and tighten the bolts to connect foundation tree B and the concrete foundation. Contact with A is made of synthetic resin strip plate 1,
1'.

Incidentally, bolt holes are drilled at desired locations in the strip plates 1, 1' during construction.

(e) Effects of the invention As mentioned above, the invention is to sandwich a synthetic resin strip impregnated with an insect repellent between the concrete foundation and the foundation wood to cut off contact between the foundation and the foundation wood. Therefore, the foundation wood does not absorb moisture from the foundation, but since the shingles are impregnated with insect repellent, the foundation wood will not be corroded by moisture or attacked by pests, so it can be used for construction. It is highly effective as a corrosion prevention board for foundation wood. In particular, in the present invention, the strip plates are made up of a pair of left and right plates, with hook-shaped bent parts on the outer edges and cutouts for joining on the inner edges, so that the thickness of the concrete foundation can be adjusted. Since it is possible to closely and easily match the strip plate to the top surface of the foundation while adjusting the degree of joint of the strip plate accordingly, the work becomes extremely easy, and the labor required for the work can be greatly reduced.

[Brief explanation of the drawing]

FIG. 1 is a perspective view of a synthetic resin strip plate according to the present invention. Figure 2 is a slope view showing the state in which the strip plate is sandwiched between the concrete foundation and the foundation wood. In the figure, 1 and 1' are synthetic resin band plates. 2 and 2' are bent parts. 3 and 3' are notches. 4 and 5 are bolt holes. A is concrete foundation. B is the foundation wood. C is for bolt.
