Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for constructing a basement, in which a roof panel, wall panels, and floor panels are stretched over a basement space dug into the ground to form a basement. It is.

[Prior art and its problems]

BACKGROUND ART In recent years, with the rise in land prices, there has been an increasing tendency to construct basements so that not only the above ground but also the underground space can be used as living space in order to make effective use of land.

However, when constructing a basement near an existing above-ground building, the height of the eaves of the above-ground building,
Due to restrictions imposed by the height of the ceiling, when digging a basement space, it is difficult to drive piles because the long piles get caught in the eaves, soffit ceiling, etc. And,
There is a drawback that it is difficult to remove the piles after the pile retaining work, and it is actually difficult to construct a basement near a building above ground.

[Purpose of the invention]

The present invention was made in order to eliminate the above-mentioned conventional drawbacks, and when performing pile retaining work, a plurality of piles are successively inserted into pile insertion holes that have been dug in advance. The piles can be easily driven in, and by using the piles as pillars in the basement without removing them after the pile retaining work, there is no need for the time-consuming work of removing the piles, and the piles can be easily placed near the above-ground building. The purpose of the present invention is to provide a method of constructing a basement by which a basement can be constructed.

[Disclosure of the invention]

For example, as shown in FIG. 1, the present invention provides a plurality of pile insertion holes 3, 3 in the ground 2 near the above-ground building 1, in accordance with the positions where the pillars of the basement to be constructed are installed. ..., and then, as shown in FIGS. 2 and 3, in the pile insertion holes 3, 3, ...
The multiple piles 4, 4, etc. that make up the pillars of the basement are successively added and inserted, and then
As shown in the figure, an upper beam material 5 is interposed between the upper ends of the opposing piles 4, 4 to connect and integrate them, and the earth and sand 6 inside the piles 4, 4, ... is excavated and removed. At the same time, as shown in Fig. 6, adjacent piles 4,
4. A retaining board 7 made of a control panel, a scaffold board, a keystone plate, a deck plate, etc. is fitted and stretched between the spaces to form a basement space 8 as shown in FIG. The present invention relates to a method of constructing a basement, which is characterized in that a ceiling panel 9 is fixed and stretched to a ceiling surface section of 8, a wall panel 10 is fixed to a wall surface section, and a floor panel 11 is attached to a floor surface section to form a basement.

In addition, in the above-mentioned present invention, the plurality of stakes 4, 4,
When adding... sequentially, use pillars made of steel such as H-shaped steel, U-shaped steel, and steel pipes as the piles 4, 4, and... In order to avoid being constrained by the height of the eaves and ceiling, use stakes 4, 4, ... that are cut shorter than the height of the eaves and ceiling, and in the short state near the building 1 on the ground. The piles 4, 4, . . . may be successively added to the basement by welding or bolting or through joints (connection plates) or directly by welding or bolting.

In addition, when interposing the upper beam material 5 between the upper end portions of the opposing piles 4, 4, ... to connect and integrate them, for example, as shown in FIGS. 4, 5, 7, and 8. As shown, joint beams 12 made of steel such as H-shaped steel, U-shaped steel, steel pipes, etc. are welded or bolted to the upper ends of the inner surfaces of a plurality of opposing piles 4, 4, . . . to connect them together. After that, the upper ends of the opposing piles 4, 4 are connected and integrated with the upper beam material 5 via the joint beam 12, or as in the embodiment, the joint beam 12
The upper ends of the piles 4, 4 facing each other are connected and integrated by the upper beam material 5, and as shown in FIG. Separately, welding or bolting a head joint beam 13 made of steel materials such as H-shaped steel, U-shaped steel, steel pipes, etc. (H-shaped steel in the drawings) to connect and strengthen the parts, as shown in Fig. 10. As shown in FIG. 9, the heads of the plurality of piles 4, 4, ...
After connecting and integrating the upper ends of the opposing piles 4, 4, ... through the head connecting beam 13, the upper ends of the piles 4, 4, ... are connected and integrated using the upper beam material 5, as shown in FIGS. 11 to 13. In this way, the upper ends of the opposing piles 4, 4 may be directly connected and integrated using the upper beam member 5.

Moreover, as shown in FIG. 10, the piles 4, 4,...
A crosspiece 14 made of a steel material such as an H-shaped steel, a U-shaped steel, or a steel pipe (H-type steel in the drawing) is welded or bolted to the top of the frame, and the ceiling panel 9 and the wall are connected via the crosspiece 14. When the panel 10 is fixed,
This is advantageous because the ceiling panel 9 and wall panel 10 can be installed quickly and reliably.

In addition, as shown in FIGS. 12 to 14, a mountain retaining plate 7 is fitted and stretched between the adjacent piles 4, 4, and a mountain retaining plate 7 is spaced at a certain interval inwardly of the mountain retaining plate 7.
A formwork 15 made of a control panel, a scaffold board, a keystone plate, a deck plate, etc. is stretched, and furthermore, reinforcing bars 16 are arranged between the retaining board 7 and the formwork 15, and concrete 17 is poured. A large basement can be formed.

When the floor panel 11 is fixed and stretched on the floor of the basement space 8, for example, as shown in FIG. 7, FIG. 8, and FIG. ,..., the lower ends of the inner surfaces are connected and integrated by a connecting beam 12, and the lower ends of the opposing piles 4, 4 are connected via the connecting beam 12 in the same manner as above. They may be connected and integrated by a floor beam material 18 made of steel, and the floor panel 11 may be fixed and stretched on the floor beam material 18, as shown in FIGS. 7 and 10.

In addition, when the ceiling panel 9 is fixed and stretched on the ceiling surface of the basement space 8, a roof panel, a roof material such as a synthetic resin-coated steel plate is attached and constructed above the ceiling panel 9, and the basement is completed.

〔Effect of the invention〕

As described above, the present invention involves digging a plurality of pile insertion holes in the ground, sequentially adding and inserting a plurality of piles into the pile insertion holes, and inserting an upper beam material between the upper ends of the opposing piles. At the same time, earth and sand inside the piles are removed and retaining boards are placed between adjacent piles to form a basement space, and a ceiling panel and wall parts are installed on the ceiling of the basement space. Since the basement is formed by attaching wall panels to the top and floor panels to the floor, when excavating the basement space, when driving stakes and securing the piles, it is necessary to adjust the eave height and ceiling height of the building above ground. In order to avoid such restrictions, the piles can be divided into multiple pieces and brought to a location near the building on the ground where a basement will be formed, and then the piles can be successively joined and driven into pile insertion holes previously dug in the location where the basement will be formed. , the piles can be driven easily, and the piles can be connected and integrated by interposing the upper beam material between the upper ends of the piles, and can be used as framework materials for basement columns, beams, etc., which eliminates the time-consuming work of removing piles. is no longer necessary, and a basement can be easily constructed near the above-ground building.
