Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a frame structure for constructing the foundation of a side wall of a basement.

(Prior Art) Recently, it has become common for ordinary houses to have basements from the viewpoint of effective use of site area. The shape of the basement is generally a square or a combination of squares.

When forming such a basement, generally, a hole is dug in the ground in a shape similar to the desired basement shape, and then the framework of the side wall of the basement is constructed with reinforced concrete along the circumference of this hole. There is.

(Problem to be solved by the invention) By the way, what about the side walls of the basement? 1) Not only must the interior of the basement be constructed, but it must also be made strong enough to withstand pressure from above, that is, pressure from above. Such tonosho tends to be particularly noticeable in areas where the -■- board is loose.

However, because the planar shape of conventional basements is rectangular or a combination thereof, the upper pressure has to be supported by a small area of only the part of the side wall of the basement where the upper pressure is applied, which is disadvantageous in terms of strength. becomes. This has been dealt with by increasing the number of reinforcing bars that make up the side wall framework and increasing the use of concrete, but this is a major cause of high costs when constructing a basement. This has resulted in hindering the installation of basements in general houses.

In addition, since the side walls of the basement are made of reinforced concrete, it takes a lot of time to install the framework for concrete pouring, attach reinforcing bars, etc., and this causes a significant delay in the construction period.

The present invention has been made in consideration of the above-mentioned circumstances.It is an object of the present invention to provide a frame structure for a side wall of a basement which is capable of resisting upper pressure and is advantageous in terms of cost and construction period. It is in.

(Means for Solving the Problems) In order to achieve the above points, the present invention has the following configuration. In other words, it is constructed as a cylindrical body as a whole or a rectangular cylinder close to a cylinder, and +i? i. Cylindrical body The cylindrical body is constructed by connecting at least a plurality of circumferentially divided pieces to each other.

(Operations and Effects of the Invention) As described above, in the present invention, since the basement side wall is constructed as a cylindrical body as a whole, which is a cylinder or a rectangular cylinder close to a cylinder, it is extremely strong in itself. Not only does it have excellent deformability and elegance, but the upper pressure is widely dispersed throughout this cylindrical body and the pressure is stopped, resulting in extremely high strength. This also reduces the amount of materials used, leading to cost reductions.

Moreover, since the cylindrical body is constructed by connecting divided pieces divided in the circumferential direction, each divided piece can be made small, which is advantageous for manufacturing or transportation. This means that each divided piece must be -L
This means that all that is required is to manufacture the parts at Bajun and then connect the divided pieces at the site where they are installed in the basement, reducing the labor required for site work and shortening the construction period. Of course, by standardizing the divided pieces, it is also possible to standardize the frame structure of the basement side wall itself. This also pushes forward the use of prefabrication, which has been particularly developed in recent years, for basement construction. Even H is advantageous.

(Example) Examples of the present invention will be described below based on the attached drawings.

In FIG. 1, a building 2 is constructed on a site 1, and a basement 3 is constructed below this building 2. , and the floor 4 of the building 2 also constitutes the ceiling of the basement 3. In addition,
In Fig. 1, the entrance to the basement 3 is indicated by 5, the stairs for going up and down to the basement room F 2 are indicated by 6, and the floor of the basement 3 (made of concrete) is indicated by 7. has been done.

The side wall 11 of the basement 3 has a bicylindrical shape as shown in FIG. 2 or 3, and in the embodiment, the diameter thereof is approximately 5 m. Of course, this side wall 11 is installed along the circumferential surface of a circular hole 12 dug in the site 1.

(As shown in FIG. 3, the frame of the wall 11 is constructed as a desired cylindrical assembly X by connecting a number of divided pieces 13 in the upper and lower directions and in the circumferential direction of the side wall 11. An example of piece 1:3 is shown in Figs. 4 and 5.Specifically, the divided piece 13 includes a receiving plate 21 having a large area and an arcuate cross section, and a receiving plate 21 on the upper, lower, left and right sides of this receiving plate 21. It has a pair of connecting flange portions 22 and a pair of left and right connecting flange portions 23 arranged in series,
Furthermore, it has reinforcing ribs 24 extending from side to side below F. Each connecting flange portion 22, 23 has a connecting hole 25 at a predetermined position, which is used to connect another divided piece 13.
is opened. Then, by using the bolts 26 and nuts 27 inserted through the connecting holes 25, the divided pieces 13 are connected to each other below and to the left and right.

1. The divided pieces 13 as described above are preferably made of iron or a material containing iron as a main component so that they have excellent strength and can be formed at low cost. When casting, it is preferable to use ductile cast iron, for example, and the parts 21 to 25 can be formed simultaneously during casting. In addition, when some or all of the parts 21 to 24 are constructed from separate members, each part is formed in advance from a steel plate and later integrated by welding or the like. It is preferable that such divided pieces 13 be formed in advance at a factory or the like.

The procedure for forming the basement 3 is as follows.

First, a hole 12 having a shape corresponding to the desired basement shape, that is, the outer shape of the cylindrical assembly X to be used, is dug in the site 1.

Next, a large number of divided pieces 13 are connected to each other within the hole 12 using bolts 26 and nuts 27 to form a cylindrical assembly X. In this case, the tube-like assembly Form it by piling it up.

It is preferable to fill the gap between each divided piece 13 with a ready-made joint material (sealing material).

As a result, the frame structure of the side wall 11 is completed.

After this, the basement interior materials may be attached using the mounting brackets, etc. that have been caulked and attached to each divided piece 21 (on the side that becomes the inner surface of the cylindrical assembly X). Of course, a heat insulating material can also be filled between this interior material and the receiving plate 21.

FIG. 6 shows another embodiment of the present invention, in which the same components as those in the previous embodiment are given the same reference numerals, and the explanation thereof will be omitted. In this embodiment, the cylindrical assembly X is configured as a regular octagonal cylindrical body. The advantage of this embodiment is that there is no need to curve the divided pieces 13.

FIG. 7 shows still another embodiment of the present invention, in which the structure of the dividing piece 31 is different from that shown in FIGS. 4 and 5. That is, this divided piece 31 has a divided structure into a main framework 31A and an outer wall material 3113.

The main framework 31A includes a pair of north-up connecting plates 32 and a pair of left and right connecting plates 33!・It has reinforcing ribs 34 that connect the lower connecting plates 32 and lining 36 made of iron plate.

The outer wall material 3113 is formed of, for example, a wooden board and is fixed to the main framework 31A with a predetermined gap using the mounting brackets 35 that are welded to the main framework 31A in advance. Ru. Note that this fixing is preferably performed in advance before connecting the divided pieces 31 to each other. For things constructed in this way,
By pouring concrete between the main framework 31A and the outer wall material 31B, the space between the outer wall material 3113 and the lining board 36 is filled with concrete.

Although the embodiments have been described above, the cylindrical assembly X may be formed by being divided at least in the circumferential direction. In other words, this circumferential length is extremely long, corresponding to the entire circumference of the basement;
This is because there is no need for support for the transportation of the divided pieces 13 or for the operator who connects them. In addition, as a rectangular cylinder close to a cylinder, it is sufficient to use a rectangular tube with an angle of E, although it varies depending on the radial length of the basement 3. Note that it is preferable to fill the space between each connecting piece with a packing to ensure sufficient sealing performance.
