BRIEF DESCRIPTION OF THE DRAWINGS FIG.
This will be described with reference to FIG.

In the method for constructing an office building of a gas station according to the present invention, first, as shown in FIG. 1, a foundation forming portion surrounding a floor ground 12 of an office building construction site 10 in a gas station construction site. The base groove 14 having a depth of about 20 to 60 cm is dug and formed.

The base groove 14 is formed so that the outer wall 14a is substantially vertical and the inner wall 14b is inclined sideways as shown in the figure. There is no particular limitation on the width of the foundation groove, but in the case of a two-story office, it is about 60 cm,
It is about 30cm in the case of a one-story office.

Next, crushed stones 16 are laid on the bottom of the foundation groove 14 and the floor ground 12 (FIG. 2). After laying the crushed stone 16, it is preferable that the waste concrete 18 be hit only on the bottom of the foundation groove 14, but it can be omitted.

After that, the ground 1 and the floor 1
The reinforcing bar 20 is arranged on the upper surface 2 (FIG. 3). A formwork 22 is set on the outer wall surface 14a of the foundation groove 14 (FIG. 4). The upper end of the formwork 22 is located above the upper end of the foundation groove 14 and is at the same height as the floor of the office to be formed.

Next, concrete is driven into the foundation groove 14 and the floor ground 12 to form a foundation concrete 24 and a floor concrete 26 (FIG. 4). By making the foundation 24 small and not digging deep as in the present invention, the amount of root cut is reduced by 60%, the concrete formwork is only the outer formwork, the amount of mold material is reduced by about 50%, and the amount of reinforced concrete is reduced. Has a great advantage that the construction period is reduced by about 50%, the construction period is reduced by about 60%, and the construction cost is reduced by about 50%. Also,
It can be set on any soft ground other than the swamp, which has the effect of eliminating the need to hit piles. Since the foundation 24 is shallow, the shoring work becomes unnecessary and the work becomes safe.

At the time of the above-mentioned concrete driving,
An anchor 28 is installed on the foundation concrete 24 (FIG. 5). Via the anchor 28, the frame 3 of the office wall is formed on the foundation 24 using a lightweight steel frame by a brace method.
Construct 0. The frame 30 is composed of columns 30a, beams 30b, and braces 30c. Further, a roof 32 is mounted on the skeleton 30. (Fig. 5)

As in the present invention, making the foundation 24 small and not digging deeply can be realized by reducing the weight of the portion above the foundation 24. Therefore, as described above, it is essential that the frame be made of a lightweight steel frame and be constructed by the brace method.

By using a lightweight steel frame in this way, the amount of steel frame is reduced by about 60% and the construction cost is reduced by about 30% as compared with the conventional steel frame.
There is an advantage that work safety is increased without requiring large heavy equipment.

On the other hand, in the conventional structure in which a frame is formed by a ramen method using a heavy steel frame, it is essential to form a large foundation by digging it deeply.

A panel 34 is attached to the skeleton 30, forming an outer wall of the office (FIG. 5). The panel 34
It is preferable to use cement siding or siding wiping with an iron plate.

In the case of the conventional outer wall covering, the outer wall siding is put together with the base of the rim at the site, so that the work is not easy. However, according to the present invention, since the outer wall covering can be panelized in a factory, in that case, the outer wall covering can be transported to the site in a truckable size, and can be mounted on the site, thereby simplifying the operation. You.

That is, since the panel 34 is manufactured in the factory, the work is carried out overlapping with the site, so that the construction period can be reduced by about 90%, the construction cost can be reduced by about 20%, and the position of the site for the work in the factory can be reduced. Since there is no work in a bad place, there is an advantage that the safety of construction is ensured. In the present invention, it is of course possible to perform exterior wall siding on site.

[0027]

As described above, according to the present invention, when building an office building of a gas station, the same functions and safety as those of the office building by the conventional method are secured, and the cost is reduced in a short time and at a low cost. The great effect of being able to build is achieved.
