Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a residential foundation structure, and more particularly to a residential foundation structure including a concrete base portion and a rising portion provided upright on the base portion.

[0002]

2. Description of the Related Art In a conventional residential basic structure 1 of this type shown in FIG. 30, both a base portion 2 and a rising portion 3 provided upright on the base portion 2 are made of concrete.
When forming the basic structure 1, the base portion 2
Since it is difficult to simultaneously support the mold of (1) and the mold of the rising portion 3 at the same time, the concrete of the base portion 2 is poured and then the concrete of the rising portion 3 is poured.

[0003]

In the prior art, since concrete was cast in two separate steps, there was the problem of poor workability. Therefore, there is a demand for a technique for eliminating the trouble of double-casting concrete, and an example thereof is disclosed in Japanese Patent Laid-Open No. 3-33327.
In this conventional technique, a rising portion is formed using a lattice structural member in which a diagonal member is arranged between an upper chord member and a lower chord member, and the concrete of the base portion is supported while the lattice structural member is discarded and is supported on concrete. After being placed, an outer surface finishing material such as ALC is attached to the surface of the lattice structure member. According to this conventional technique, since the rising portion is formed by the lattice structure member, it is not necessary to hit the concrete twice, but since it is necessary to attach the outer surface finishing material to the surface of the lattice structure member, The workability was poor.

Therefore, a main object of the present invention is to provide a foundation structure for a house which can dramatically improve the workability.

[0005]

SUMMARY OF THE INVENTION The present invention is a basic structure for a house including a concrete base portion and a rising portion provided upright on the base portion. Characterized in that a plurality of metal rising units including a reinforcing rib formed so as to be orthogonal to the main body are connected to form a rising portion,
It is a basic structure for a house.

[0006]

Since the rising part is formed by connecting the rising units made of metal, it is not necessary to hit the concrete twice. Further, since the plate-shaped main body of the rising unit constitutes the surface of the rising portion, it is not necessary to attach the outer surface finishing material.

[0007]

According to the present invention, workability can be dramatically improved. The above-mentioned objects, other objects, features and advantages of the present invention will become more apparent from the following detailed description of the embodiments with reference to the drawings.

0a, central reinforcing rib 20e and side end reinforcing ribs 20c
And 20d are formed only on the inner surface side of the main body 18, but the lower end reinforcing ribs 20b are also formed on the outer surface side of the main body 18. Therefore, the width of the lower end reinforcing rib 20b is set wider than the other reinforcing ribs.

Then, on the upper surface of the upper end reinforcing rib 20a,
A protruding piece 22 is formed so as to rise upward so as to be flush with the upper outer surface of the main body 18, and a plurality of substantially L-shaped anchor portions 24 are formed on the lower surface of the lower end reinforcing rib 20b. Further, the corners formed by the upper end reinforcing ribs 20a and the central reinforcing ribs 20e and the side end reinforcing ribs 20c and 20d are
A joint portion 26 for joining the other rising unit 16 is formed. Further, the joint portion 26 and the upper end reinforcing rib 20
a, lower end reinforcing rib 20b, side end reinforcing ribs 20c and 2
A hole 28 for inserting a bolt is formed at each predetermined position of 0d.

When the foundation structure 10 is formed by using the rising unit 16 and the like, as is well understood from FIGS. 1 and 4, first, the groove 30 is excavated at the place where the foundation structure 10 is to be formed. The rubble stone 32 is laid on the bottom of the groove 30, and the discarded concrete 34 is placed on the upper surface of the rubble stone 32. Then, after the waste concrete 34 is cured, the plurality of rising units 16 are arranged at predetermined positions via the support member 38, and the rising units 16 are assembled by sequentially connecting the rising units 16, and then the waste concrete 34 is discarded. Assemble the mold 36 on the upper surface.

Here, the support member 38 includes a substantially plate-shaped main body 40 along the upper surface of the discarded concrete 34.
On the upper surface of the lower end reinforcing rib 20b of the rising unit 16

Bolts 42 are provided vertically. When the support member 38 is attached to the rising unit 16, each bolt 42 is screwed with the first nut 44a (FIG. 1), the tip of the bolt 42 is inserted into the hole 28, and the lower end reinforcing rib 20b is inserted.
The second nut 44b is screwed into the bolt 42 protruding from the upper surface of the.

When the two rising units 16 are connected in a straight line when the rising portions 14 are assembled, as can be seen from FIG. 4, the side end reinforcing ribs 20c of one rising unit 16 and the other rising unit 16 are well understood. 16 side end reinforcing ribs 20d in contact with each hole 2
8 through the bolt 46a, the bolt 46a nut 46
Screw b together to join the two. For example, when assembling the rising portion 14 as shown in FIG. 5, in addition to connecting the rising units 16 in a straight line, it is necessary to connect in an L shape, a T shape, or a cross shape.
For example, a substantially L-shaped joint 48 as shown in FIG. 6, a substantially T-shaped joint 50 as shown in FIG. 7, or a substantially cross-shaped joint 52 as shown in FIG. 8 is used. Further, when the length of one side of the rising portion 14 is to be extended by a predetermined length, the substantially I-shaped joint 54 as shown in FIG.
Is inserted between. Each of the joints 48, 50, 52 and 54 has a side end reinforcing rib 20 of the rising unit 16.
Holes for inserting bolts corresponding to the holes 28 formed in c and 20d are formed.

The rising portion 14 is assembled in this manner, and the reinforcing bar 56 is placed in the mold formed by the mold 36.
After that, the concrete of the base portion 12 is placed. After the concrete (base portion 12) is hardened, the mold 36 is removed and the groove 30 is backfilled with earth and sand. After the foundation structure 10 is formed, a pillar 60 is attached to the upper surface of the rising portion 16 (the upper surface of the upper end reinforcing rib 20a) using bolts and nuts 58 as shown in FIG. The outer wall panel 64 is attached so that the lower end of the plate 62 overlaps the outer surface of the projecting piece 22.

According to this embodiment, it is not necessary to hit the concrete twice, and it is not necessary to attach the decorative material to the outer surface of the rising portion 14, so that the workability is dramatically improved as compared with the prior art. it can. Also, the upper end reinforcing rib 20a
It is possible to reliably prevent rainwater from entering the inside of the outer wall panel 64 by the projecting piece 22 formed on the upper surface of the. In the above-described embodiment, the case where the rising unit 16 (main body 18) is formed with a lysine-like pattern on the outer surface is shown. However, instead of this, for example, the one-character tone as shown in FIG.
As shown in Fig. 12, as shown in Fig. 12, line as shown in Fig. 13, as shown in Fig. 13, as shown in Fig. 14, as shown in Fig. 14, as shown in Fig. 15, as shown in Fig. 16. A small pattern overlapping tone or a small pattern tone pattern as shown in FIG. 17 may be formed.

Further, in the above embodiment, the joints (FIGS. 6 to 8) are used when connecting the rising units 16 in an L shape, a T shape, or a cross shape, but instead of this,
For example, as shown in FIGS. 18 to 20, the rising portions 16 may be directly joined to each other by using the joining portion 26, or as shown in FIGS. 21 to 23, the side end surface of the rising unit 16 ( Side reinforcement ribs 20c or 20
d) may be formed obliquely, and the side end surfaces may be abutted and joined together.

Further, the main body 1 in the rising unit 16

Instead of the rising unit 16, for example, a rising unit 68 as shown in FIG. 25 may be used. In the rising unit 68, the lower end reinforcing rib 20b is provided in the main body 1
2 in that it is formed only on the back surface side of 8, the anchor portion 24 is not formed on the lower surface of the lower end reinforcing rib 20b, and the protruding piece 22 is formed at a predetermined distance from the front end edge of the upper end reinforcing rib 20a. It differs from the rising unit 16 shown. When assembling the rising portion 14 using this rising unit 68, the rising unit 68 cannot be stably supported only by the support member 38, and therefore, as shown in FIG.
A support 70 is provided for suspending and supporting the.
In this rising unit 68 as well, an arbitrary pattern (FIGS. 3, 10 to 17) is formed on the surface of the main body 72, and a ventilation port (FIG. 24) is formed if necessary.

Further, in the above-described embodiment (FIGS. 1 and 26), the base portion 12 is formed on site, but
For example, as in the basic structure 74 or 74 'shown in FIG. 27 or 28, the base portion 12 formed in the factory is carried into the site, and is positioned on the upper surface of the discarded concrete 34 cast on the upper surface of the split stone 32. , Then the base 12
The anchor bolts 76 and the nuts 78 embedded in the
8 may be attached. In this case, the base portion 12 is formed by dividing the base portion 12 into a predetermined length in consideration of transportability, and each base portion 12 is, as shown in FIG.
It joins using the joining member 80 and the bolt 82.
