Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a multi-storey basement room or other basement structure.

[Prior art]

In recent years, as land prices have risen, there is an increasing tendency to construct underground structures such as basements so that not only above-ground but also below-ground can be used as living spaces in order to effectively use the land. On the other hand, when the above-mentioned underground structure is constructed by a panel construction method, a floor panel, a wall panel and a roof panel are built in a hole to be dug in the ground to construct the underground structure.

[Problems to be Solved by the Invention]

In the above-mentioned conventional underground structure, there has been a problem that only the underground structure of one-story underground has been put into practical use. The present invention has been made to solve the above-mentioned conventional problems, and provides a method for constructing a multi-storey underground structure capable of constructing a multi-storey underground structure easily and quickly. This is an issue.

[Means for Solving the Problems]

In order to solve the above-mentioned problems, the present invention provides a floor panel and a roof panel which form a floor and a roof part of each floor by stretching and fixing a face material on the surface of a panel frame made of steel, and the height of a plurality of floors. A large-sized wall panel having a height of a plurality of floors to form the wall portion of the floor, and further laying a floor panel constituting the floor portion of the lower floor at the bottom of the hole to be dug in the ground. A large-scale wall panel that constitutes a wall portion of a plurality of floors is erected and fixed to the upper part, and a roof panel that constitutes a roof part of the lower floor is installed and fixed to the middle portion of the large-scale wall panel and fixed to the basement structure of the lower floor. In addition to the above, the roof panel constituting the roof portion of the upper floor is erected and fixed to the upper end of the large-sized wall panel to construct an underground structure of the upper floor.

【Example】

Hereinafter, the present invention will be described in detail with reference to the drawings shown as examples. The present invention, for example, as shown in FIG. 1 to FIG. 5, stretches a steel plate or other face material 2 on the surface of a panel frame 1 made of chevron steel, grooved steel or other shaped steel, and welds and fixes it. And floor panels 3 that make up the floor and roof of each floor of the underground structure
And a roof panel 4 and a large wall panel 5 having a height of a plurality of floors to form a wall portion having a height of a plurality of floors (a wall portion extending over the entire height of an underground construction of a plurality of floors), and further,
The floor panels 3, 3 forming the floor portion of the lower floor are laid at the bottom of a hole (not shown) to be dug in the ground, and the floor panel 3,
3, ... Large wall panels 5, 5, ...
And the nuts 7 are fastened and fixed, and the large wall panels 5, 5
Roof panels 4a, 4a that make up the roof of the lower floor in the middle of
And the bolts 6 and nuts 7 are fastened and fixed to construct an underground structure on the lower floor and the large wall panels 5, 5
Roof panels 4b, 4b that form the roof of the upper floor at the upper end of ...
The present invention relates to a method for constructing a multi-storey underground structure, characterized by constructing an underground structure on the upper floor by erection of the above and fastening and fixing with bolts 6 and nuts 7. 1 to 3 show that the roof panel 4a on the lower floor is installed between the large wall panels 5 and 5 and the roof panel 4b on the upper floor is mounted on the upper ends of the large wall panels 5 and 5. An example in which the roof panel 4a on the lower floor and the roof panel 4b on the upper floor are both fitted between the large wall panels 5 and 5 is shown in FIGS. Here is an example: Further, in the present invention, the floor panels 3 and 3 adjacent to each other,
When the roof panels 4, 4 and the large wall panel 5, 5 are connected and fixed to each other, for example, as shown in FIG. 6, floor panels 3, 3, roof panels 4, 4 and a large wall panel 5, It suffices to bring the connecting end face portions of 5 into contact with each other, and tighten and fix them with bolts 6 and nuts 7. Although the two-story underground structure is illustrated in the embodiments of the present invention shown in FIGS. 1 to 5, it is needless to say that an underground structure having three or more floors can be constructed in the same manner as the above-mentioned embodiment.

【The invention's effect】

INDUSTRIAL APPLICABILITY As described above, according to the present invention, a surface material is stretched and fixed on the surface of a panel frame made of shaped steel to form a floor portion and a roof portion of each floor to form a floor panel and a roof panel, and a wall portion having a plurality of floors. To form a large wall panel having a height of a plurality of floors, further laying a floor panel constituting the floor of the lower floor at the bottom of the hole to be dug in the ground, a plurality of on the floor panel A large-sized wall panel that constitutes the wall portion of the floor is erected and fixed, and a roof panel that constitutes the lower-floor roof portion is erected and fixed in the middle of the large-sized wall panel to construct an underground structure on the lower floor. At the same time, a roof panel that constitutes the roof part of the upper floor is erected on the upper end of the large-scale wall panel, and is firmly fixed to construct an underground structure of the upper floor to construct a multi-storey underground structure. The steel section that is made to exert sufficient strength as the frame structure of the underground structure and the floor panel. , A multi-storey underground structure can be easily and quickly constructed by simply building and fixing large-scale wall panels and roof panels one by one, and in addition, the wall panel has a height dimension corresponding to multiple floors. Since it is made of large-sized wall panels, it is extremely advantageous in terms of strength and work efficiency.
