Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a foundation structure suitable for a wooden building that uses thick pillars that penetrate the first and second floors to support the roof, and is relatively inexpensive. In order to promote the use of 8-inch square and 6 m long through-posts, which are available in Japan, we particularly strengthened the bases that support the through-posts, and also strengthened the bridge between the through-posts with square lumber bases made of wood of normal thickness. This relates to a basic structure with improved joints.

[Conventional technology and its problems]

According to traditional construction methods, the pillars are supported on the foundation stones, the foundation stones are placed between the pillars to support the wood that serves as the foundation, and the corner pillars are thicker than the other pillars. is being carried out.

However, in these conventional construction methods, materials of approximately the same thickness are generally used for the pillars and the foundation, so
It was common practice to support the corner pillars by slightly strengthening the base of the cloth foundation.

Therefore, when thick cedar wood, for example, 8 square inches, is used not only for the corner portions but also for the pillars, it is insufficient in terms of strength as a supporting structure. Furthermore, it is uneconomical to make the entire cloth foundation strong enough to withstand thick through-pillars.

[Purpose of the invention, means for solving the problem]

The purpose of this invention is to solve the above-mentioned problems and to obtain a foundation structure with high strength and excellent usability for supporting thick through-pillars and a relatively thin wooden base that connects them. , consists of a plurality of bases that support the through-pillars, and a cloth foundation installed between these bases, the ends of the cloth foundations are provided at a predetermined distance from the bases, and the ends of each cloth foundation are are characterized by the fact that they are interconnected by hypotenuse foundations that avoid the base.

[Effect]

The thick through-pillars were firmly supported by multiple bases, and the foundations were supported by the fabric foundations installed between them, so that the through-pillars with large load weights and the foundations that received other loads could not be affected by the load. Moreover, since the cloth foundations are interconnected, the strength will not decrease.

〔Example〕

The present invention will be explained below with reference to the illustrated embodiments. In the figure, 1 is a wooden building employing the present invention, which is composed of a foundation structure F and a building B built on it. 2 is a through-pillar that constitutes building B; 3 is a roof portion supported by it;
4 is attached around the foundation structure F, so-called,
It's a dog run.

As shown in Figures 3 to 4, the basic structure F is
A plurality of bases 5 that support the through columns 2 and those bases 5
It consists of a cloth foundation 6 provided between.

The plurality of bases 5 have the same configuration as those supporting the corner pillars and those supporting the intermediate pillars, and the bases 5 have the same structure.
a and the foundation concrete 5 installed on top of it
b, and a foundation stone 5e anchored with an anchor bolt 5d on a ground surface portion 5c provided in the center of the foundation concrete 5b. In this example, the foundation stone 5e is made of marble. In addition,
The part of the foundation concrete 5b below the ground surface 5d is buried underground, and is usually concreted at the same time as the abandoned foundation part 6e of the cloth foundation 6, which will be described later.

On the other hand, the cloth foundation 6 has an interpolation part 6a provided between the bases 5 and an oblique side part 6b connecting the ends of the interpolation part 6a obliquely around the base 5 or connecting the base 5 with each other. It is composed of a side road foundation 6d consisting of a parallel part 6c that avoids the shape of a letter. 6e indicates a discarded foundation part that forms the underground part of the cloth foundation 6. A space 7 is provided at a predetermined distance between the interpolation part 6a and the foundation stone 5e of the base 5. This space 7 is required to have a minimum width of about 10 cm, which is enough for a domestic cat to pass through.
6f indicates a ventilation port provided in the interpolation portion 6a, and 6h indicates a ventilation port provided in the side road foundation 6d.

Next, the wooden structure of the base 5 will be explained with reference to FIGS. 5 and 6. The through post 2 is an 8-inch square cedar post, and the wood has been trimmed so that the core of the wood is in the center.
It is placed on the foundation stone 5e with its end 2a facing down. 5f is a ventilation groove carved on foundation stone 5e, with a width and depth of around 10 mm. Therefore, since the foundation stone 5e is made of marble, there is no water intrusion into the wood end 2a, and drying by ventilation is good, so that regardless of the type of wood, it can be used for a long time.

Near the lower end of the through-post 2, there is a dovetail groove 2b that engages with an engaging protrusion 8a provided at the end of the base 8 attached to the cloth foundation 6, and a decorative plate that covers the outer surface of the base 8, a so-called larch plate 9. A mounting groove 2c is carved therein. 2d is a vertical groove for preventing cracks.

〔Effect of the invention〕

As described above, this invention consists of a plurality of bases that support through columns and a cloth foundation provided between these bases, and the ends of the cloth foundation are provided at a predetermined distance from the bases. The ends of each cloth foundation are connected to each other by a side path foundation installed avoiding the base, allowing the use of thick through columns without putting a large burden on the cloth foundation, resulting in high strength and ease of use. This has the effect of providing an excellent basic structure.
