Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for attaching a termite-proof board to the concrete foundation of a house to prevent termite invasion.

[Conventional technology]

Conventional termite prevention boards are arranged so as to be sandwiched between a concrete foundation and a foundation placed on top of the concrete foundation, and are configured to repel termites at a portion that protrudes laterally from the concrete foundation.

Therefore, the termite prevention board is installed as follows.

In other words, the top surface of the concrete foundation is treated with tar or pitch, and then the termite-proof board is placed on top of the concrete foundation, and the foundation is placed on top of the termite-proof board, and the concrete foundation is placed in advance. It is installed by using the provided bolts and tightening them with nuts.

[Problem that the invention seeks to solve]

According to the conventional construction method described above, it is undeniable that a slight gap is created between the constructed termite prevention board and the concrete foundation, and termites that enter through this gap can enter the bolt holes formed in the termite prevention board, etc. There is no denying the fear that the foundation will be reached through this process. Furthermore, the construction method itself cannot be said to be simple.

[Means for solving problems]

The gist of the configuration of the present invention is that, in an installation method of installing a termite-proofing plate that protrudes horizontally from the concrete foundation of a house, the lower part is placed on the inner surface side of the assembled formwork for the concrete foundation. A termite prevention plate member having an embedded joint facing inward is temporarily joined to the plate, concrete is poured into the formwork, and after a prescribed drying period, the formwork is removed. This is a method of installing a termite prevention board by folding back the upward facing termite prevention board member fixed in the middle of a concrete foundation in the horizontal direction.

In some cases, before or after the above step of folding back the termite-proofing board member in the horizontal direction, a step of further bending the tip of the ruler termite-proofing board member, for example, downward, is inserted.

Note that the steps up to the assembly of the formwork described above are the same as those of the conventional method. Lay chestnut stones (gravel) in the designated positions,
Pour concrete on top of it and assemble the formwork on top of the concrete.

The above-mentioned bonding of the termite-proof plate member to the inner surface of the formwork can be carried out by pressing it down using a spacer, using an adhesive that can be peeled off by an appropriate blow, or by bending the upper end of the termite-proof plate member. It is also possible to form a stop part in advance and use this to suspend the joint from the upper end of the formwork. Any suitable joining means may be freely employed.

Further, the above-mentioned embedded joint part can freely adopt various configurations, but for example, the lower end of the termite prevention plate member is bent to form a bent piece, and joining holes are made in this at appropriate intervals. Can be configured. Alternatively, horizontal anchors may be fixed at appropriate intervals near the bottom of the ant-proof plate member.

[Effect]

In the present invention, with the above configuration, the termite prevention plate can be reliably installed in the middle of the concrete foundation. It does not have the drawbacks of the conventional example, has a simple structure, and has a simple construction method.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

The present invention is applied to foundation work when building a new house. This embodiment is also one example.

As shown in FIG.
4 and lay 4 pieces of chestnut stone (gravel) on the bottom. After that, pour concrete 5 on top of the chestnut stone 4,
Concrete foundation 1 on top of this abandoned concrete 5
Assemble formwork 6 for

Next, an anti-termite plate member 7 is temporarily joined to the inner surface of the formwork 6. Bonding can be done by using spacers or adhesives, but in this example an example is shown in which temporary fixing is performed using adhesives. Join on the side. An embedded coupling piece 8 facing inward is bent at the lower end of the termite prevention plate member 7. As shown in FIG. 3, this embedded coupling piece 8 is provided with a large number of coupling holes 9, 9, . . . formed at appropriate intervals.

Incidentally, instead of the termite-proofing plate member 7 described above, a termite-proofing plate member 17 as shown in FIG. 4 may be employed. This is an anchor 18 instead of the embedded coupling piece 8.
It is composed of

Thereafter, as shown in FIG. 2, concrete is poured into the formwork 6. After the concrete foundation 1 is solidified after a suitable drying period, the formwork 6 is removed.

After removing the formwork 6 as described above, the upper end of the upwardly facing termite prevention plate member 7 fixed in the middle of the concrete foundation 1 by the embedded connecting piece 8 is bent outward with respect to the concrete foundation 1. The termite-repelling piece 10 is formed by folding the termite-repelling member 10, and then the entire termite-proofing plate member 7 is folded back horizontally from the base.

11 in the figure is the base.

However, in this embodiment, since the termite-proofing plate is attached and constructed as described above, the termite-proofing plate can be reliably attached in the middle of the concrete foundation. It has a simple structure and a simple construction method.

Furthermore, an anti-termite board that can reliably repel termites has been constructed.

〔Effect of the invention〕

Since there is no possibility that a gap will be created between the termite prevention board placed by the construction method of the present invention and the concrete foundation, the risk of termite invasion is extremely low. Furthermore, the construction method of the present invention is very simple, and the termite prevention board can be installed economically.
