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 wall 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 the ground, it takes a lot of time and effort to construct the above-ground structure using the column and beam method inside a hole that is difficult to work.
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 erected a steel column on the steel floor panel. Support steel columns,
Furthermore, a steel wall panel is attached to the steel pillar, and a steel roof panel is attached 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, for example, as shown in FIGS.
Steel floor panels (2), (2), ... are laid at the bottom of the holes drilled in the ground (1) to form a space for underground structures,
Steel pillars (3), (3), ... are erected at desired positions of the steel floor panels (2), (2), ..., and steel floor panels (2), (2), …… steel columns (3), (3), ……
, And bolted steel wall panels (4), 4),... To the side surfaces of the steel columns (3), (3),.
In addition to being fixedly attached by other means, a steel roof panel (5) is provided above the steel wall panels (4), (4),.
(5) The present invention relates to a method for constructing an underground building, characterized in that the underground building is constructed by attaching and fixing bolts or the like with bolts or the like. In the present invention, the steel floor panel (2), the steel wall panel (4) and the steel roof panel (5) include
For example, as shown in FIGS. 1 to 4, one or both sides of a panel frame (6) made of a mold steel such as a channel steel or an angle steel are coated with a steel plate (7), and are welded, screwed, or the like. It is advisable to use a fixed panel. When a steel column (3) is erected on a steel floor panel (2), for example, as shown in FIGS. 1 to 4, a steel plate (3) is attached to the lower end of the steel column (3). Weld the pieces and attach the flange pieces (8)
And the mounting flange piece (8) is attached to the steel floor panel (2).
The steel (3) may be erected by placing it on the panel frame (6) and the panel middle rail (9) and bolting (10). When the steel roof panels (5), (5),... Are mounted above the steel wall panels (4), (4),. , Steel roof panels (5), (5),... Are placed on the upper ends of the steel wall panels (4), (4),. Alternatively, a mounting bracket may be protruded from the outer peripheral body of the upper end of the steel column (the outer peripheral body located above the steel wall panel), and the steel roof panel may be supported, fixed and mounted by the mounting metal. Good. In FIG. 4, (11) is a steel column of the above-ground building which can be constructed above the underground building, and the steel column (11) of the above-mentioned building above the steel column (3) of the above-mentioned building. Attach the mounting flange pieces (12) and (13) projecting to the continuous ends of the steel columns (11) and (3) as well as the steel columns (11) and (3). Then, it may be connected and integrated. When attaching the steel wall panel (4) to the steel pillar (3), for example, as shown in FIGS. 1 to 3, the steel wall panel (3) is attached along the entire length of the steel pillar (3) in the longitudinal direction of the side surface. Piece (1
4), the steel wall panel (4) is fixed by bolting or other means through the mounting piece (14), and then the steel wall panel (4) is fixed. The projecting dimensions of the mounting flange pieces (12) and (13) protruding from the outer peripheral body of the steel columns (11) and (3) are adjusted to the mounting pieces (1).
It is convenient because it can be absorbed in 4). The underground structure constructed in the present invention may be finished by placing backfill concrete (15) on the outer peripheral surface of the structure as shown in FIGS. 1, 3 and 4, for example. .

【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, a steel column is erected on the steel floor panel, and a steel column is formed on the steel floor panel. Support, and a steel wall panel is attached to the steel pillar and a steel roof panel is attached above the steel wall panel to construct an underground structure. Since the mechanical strength of the underground structure can be significantly improved by the steel columns and the force applied to the steel columns can be dispersed and supported by the entire steel floor panel, Is constructed, a steel column is erected on the foundation, and compared to the case where the force applied to the steel column is intensively supported by the foundation, also in terms of strength,
In addition to being advantageous in terms of man-hours, the number of steel columns, the standing position, and the like can be arbitrarily selected or changed according to the desired strength, so that the steel columns can be erected, and accordingly, 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.
