Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a method of constructing an underground building in which a steel floor panel, a steel wall panel, and a steel roof panel are installed in a hole to be dug in the ground to construct an underground building.

[Prior art]

Conventionally, when constructing an underground structure, for example,
As shown in the figure, steel floor panels (B), (B), ..., steel wall panels (C),
(C), ..., and steel roof panels (D), (D),
……, is building an underground building.

[Problems to be solved by the invention]

In the above prior art, a steel floor panel (B),
(B),..., Steel floor panels (C), (C),... And steel roof panels (D), (D),. There is a problem that it may be unbearable and deformed. In addition, a technology for constructing an underground structure using a column / beam construction method different from the panel construction method has been invented. That is, as shown in JP-A-57-74435, a foundation is constructed at the bottom of a hole to be dug in the ground, and a steel pillar,
There is disclosed a technique in which a steel frame material such as a steel beam is erected to form a steel frame, and then a metal panel is attached to the steel frame to construct a basement. However, unlike on the ground, it is very troublesome to construct an underground structure using the column and beam method inside a hole that is difficult to work as described above.
Since the foundation must be constructed, steel columns must be erected on the foundation, and the forces applied to the steel columns must be intensively supported by the foundation. However, there is a problem that it is difficult to arbitrarily select or change the number of steel columns, the standing position, and the like according to the desired strength. The present invention has been made in order to solve the above-mentioned conventional problems, and can sufficiently withstand the case where earth pressure, groundwater pressure, etc. are applied from various directions, and the underground structure may be deformed. It is an object of the present invention to provide a construction method capable of easily and quickly constructing an underground building without any.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention lays a steel floor panel at the bottom of a hole to be dug in the ground, and fits a lower end of the steel column into a column mounting opening provided in the steel floor panel. A steel pillar is supported by a steel floor panel, and a steel wall panel is attached to the steel pillar, and a steel roof panel is provided above the steel wall panel. To construct an underground building.

【Example】

Hereinafter, the present invention will be described in more detail with reference to the drawings shown as examples. The present invention provides, for example, steel floor panels (2), (2) at the bottom of a hole drilled in the ground (1) to form a space for an underground structure, as shown in FIGS. ... and laying steel floor panels (2), (2), ..., steel mounting columns (3), (3),... (4),..., And the column mounting holes (4) for mounting on the steel floor panels (2), (2),.
(4), the lower ends of the steel columns (3), (3),... Are fitted and fixedly integrated, and the steel columns (3), (3),. The steel columns (3), (3), ... are supported by the floor panels (2), (2), ..., and the side surfaces of the steel columns (3), (3), ... The part is a steel wall panel (5),
(5),... Are fixedly attached with bolts and the like, and the steel wall panels (5), (5),.
, A steel roof panel (6), (6)... Is fixedly attached with bolts or other means to construct an underground building. In the present invention, as the steel floor panel (2), the steel wall panel (5) and the steel roof panel (6),
For example, as shown in FIG. 1, one or both sides of a panel frame (7) made of a mold steel such as a channel steel or an angle steel are coated with a steel plate (8) and fixed by welding, screwing, or the like. Use a panel. In addition, when the column mounting port (4) is provided in the steel floor panel (2), for example, as shown in FIG. 1 and FIG.
An opening is provided at a desired position of the steel floor panel (2), and below the opening, a channel-shaped slab, an angled slab, and other shaped slabs (9), (9), (9), and (9). ) Is welded and fixed to form a column support frame, and a column mounting port (4) is provided.
This is advantageous because the steel column (3) can be securely and firmly supported and erected. When the lower end of the steel column (3) is fitted and integrated into the column mounting opening (4), for example, as shown in FIG. , (9), (9),
Bolts (10), (10),... Protrude from the upper surface of (9), and as shown in FIG. And the lower end of the steel column (3) is inserted into the column mounting port (4) and the column mounting port (4).
The mounting flange piece (11) is placed on the peripheral edge of the bracket, and the bolt (10) is inserted through a bolt hole protruding from the mounting flange piece (11), and tightened with a nut (12). And integrate them. When steel roof panels (6), (6),... Are mounted above steel wall panels (5), (5),..., For example, as shown in FIG. The steel roof panels (6), (6),... Are placed on the upper end of the wall panels (5), (5),. A mounting bracket may be protruded from the upper outer peripheral body of the pillar (the outer peripheral body located above the steel wall panel), and the steel roof panel may be supported, fixed and attached by the mounting metal. In FIG. 1, (13) is a steel column of the above-ground building which can be constructed above the underground building, and the steel column (13) of the above-mentioned building above the steel column (3) of the underground building. Attach the mounting flange pieces (14) and (15) projecting from the continuous ends of the steel pillars (13) and (3) and connect them with bolts (16).
And a nut (17) for connection and integration, or welding and abutting portions for connection and integration. The underground structure constructed in the present invention may be finished by, for example, placing backfill concrete on the outer peripheral surface of the underground structure.

【The invention's effect】

As described above, according to the present invention, a steel floor panel is laid at the bottom of a hole to be dug in the ground, and the lower end of the steel column is fitted and integrated into a column mounting opening provided in the steel floor panel. Erecting the constituent pillars,
Since steel columns are supported by steel floor panels, and steel wall panels are attached to the steel columns, and steel roof panels are attached above the steel wall panels to construct an underground structure. By fitting and integrating the lower end into the column mounting opening of the steel floor panel, the mechanical strength of the underground structure can be significantly improved by the securely and firmly erected steel columns,
In addition, since the force applied to the steel pillar can be dispersed and supported by the entire steel floor panel, a foundation is separately constructed, and a steel pillar is erected on the foundation to form a steel pillar. Compared to the case where such a force is intensively supported by the foundation, it is advantageous in terms of strength and man-hour, and the number of steel columns, the standing position, etc. are arbitrarily set according to the desired strength. Steel columns can be easily and quickly erected by selecting or changing, so that
It can withstand even when earth pressure, underground water pressure, etc. are applied from various directions, and can easily and quickly construct an underground structure without the risk of deformation of the underground structure.
