Description

[Detailed description of the invention] This invention is intended to protect square timbers that serve as the foundation laid on the foundation from moisture when constructing a house, especially a wooden house, and to strengthen the earthquake resistance of the house assembled on the foundation. The aim is to provide a base protection board for

The conventional structure of a wooden house is to surround the square timbers that serve as the foundation on a concrete foundation, tighten and fix the concrete foundation and the square timbers that will serve as the foundation using anchor bolts planted in the concrete foundation, and then place the pillars on top of this. It is well known that after the building was assembled, various construction work was carried out to construct the house.

However, in houses built using conventional construction methods, especially wooden houses, the square timbers that serve as the foundation are enclosed directly on top of the concrete foundation, so if the concrete foundation becomes damp due to rain or other reasons, that moisture will spread onto the square timbers that serve as the foundation. This seepage caused the square timbers that serve as the foundation to corrode, shortening the useful life of wooden houses.

In addition, in the event of an earthquake, since the square timbers that serve as the foundation are enclosed directly on top of the concrete foundation, the vibrations of the concrete foundation due to the earthquake are transmitted directly to the square timbers that serve as the foundation, which in turn is transmitted to the entire house, causing damage and collapse of the house. It can also be a cause of.

The present invention was devised based on the idea of providing a building material that eliminates these drawbacks.

Examples of the present invention will be described below.

Woven fabrics, knitted fabrics, non-woven fabrics, etc. made of fibers made of natural, synthetic resins, glass, etc. are arranged in one layer or in several layers on rubber, synthetic rubber, or other elastic bodies having the same properties, and are planted on a concrete foundation 2. The anchor bolt insertion hole 1a can be formed at a location corresponding to the placement location of the installed anchor bolt 3 on one or both sides of the long board, hanging down along the side edge of the long board. The plate 4 is integrally formed to serve as a base protection plate.

Since the present invention is constructed as described above, in order to use it in the construction of a house, the first step is to place the anchor bolts 3 planted in the concrete foundation surface 5 of the foundation protection plate 1 constructed as described above. After drilling holes 1a for inserting the anchor bolts 3 at matching locations, attach the foundation protection plate 1 to the anchor bolts 3 planted in the concrete foundation surface.
The foundation protection plate 1 according to the present invention is laid on the concrete foundation surface 5 by inserting it through the anchor bolt insertion hole 1a drilled in the hole 1a, and the house is then constructed according to the conventional construction method.

Therefore, in a house built using the foundation protection plate 1 according to the present invention, the foundation protection plate 1 according to the present invention is interposed between the concrete foundation surface 5 and the square timber 6 serving as the foundation. Become.

Due to this intervention, moisture contained in the concrete foundation due to rain or other causes can be removed from the square timber 6 that serves as the foundation on which the foundation protection plate 1 according to the present invention is placed on the concrete foundation 2 and its surface 5. Since it is interposed in between, the square timber 6 that is the base is blocked by the base protection plate 1 and can be prevented from being affected by the moisture, so the square timber that is the base is prevented from corroding due to moisture. It can be prevented.

The elongated plate surface of the foundation protection plate 1 with the above structure is formed in an expanded shape in the longitudinal direction, so that when it is laid over the concrete foundation 2, the square timber 6 that will serve as the foundation is placed on top of it. Even if there is no gap between the concrete foundation 2 and the hanging plate 4 of the foundation protection plate 1, the back side of the square timber 6 presses against the inflatable surface of the foundation protection plate 1, and its weight causes the foundation protection plate 1 to
The expanded surface is deformed into a flattened shape, and as a result of this deformation, the base protection plate 1 is elastically deformed, and the hanging plate 4 begins to expand outward from the side wall of the concrete foundation.

Therefore, with this configuration, a space can be created between the concrete foundation side wall and the hanging plate 4 of the foundation protection plate 1.

Furthermore, since the foundation protection plate 1 according to the present invention is constructed as described above, the hanging plate of the foundation protection plate 1 laid on the surface 5 of the concrete foundation 2 is placed on one side or both sides of the side wall of the concrete foundation. 4 are suspended along the side edges of the elongated foundation protection plate 1 at a narrow but spaced interval from the concrete foundation side wall.

The effect of this hanging board 4 is that even if pests such as termites climb up the moist side walls of the concrete foundation 2, the back side of the foundation protection board 1 installed on the surface 5 of the concrete foundation 2 will act as a ceiling. Above that, there is a dead end, and if you want to reach the square timber 6 that will serve as the foundation, you will have to walk down the back side of the hanging board 4 of the foundation protection board 1, and in the end the ceiling will be a dead end. It does not reach the square timber that will become the base. This hanging board 4 will serve as an insect repellent.

In addition, as mentioned above, the foundation protection plate 1 placed between the concrete foundation 2 and the square timber 6 serving as the foundation also serves as a cushion material in the event of an earthquake, and the vibrations of the concrete foundation 2 are somewhat alleviated. Since it is transmitted to the square timber 6 that serves as the foundation, damage to the house can be prevented to some extent.

Although it is desirable that the above-mentioned hanging plates 4 are provided on both sides of the long foundation protection plate 1 from the above explanation, depending on the location where the house is built, it is not always necessary to install the hanging plates 4 on both sides of the foundation protection plate. 1, the above-mentioned effect can also be obtained by using the base protection plate 1 provided with the hanging plate 4 only on one side.
