CONSTITUTION:Steel plates and other panels 2 are expanded, welded and fixed to the surfaces of panel frames 1 constituted of angle bars, channel steels and other shape steels to form a large sized wall panel 5 constructing floor panels 3, roof panels 4 and a wall section having a height of plural stories of which the floor section and roof section of each story are constituted. The floor panels 3... of which the floor section of the lower story is constituted are constructed to the bottom of an excavated hole on the ground to erect the wall panels 5... on them, and they are tightened and fixed with bolts 6 and nuts 7. The roof panels 4 of the lower story are constructed to the middle of the wall panels 5, and they are tightened and fixed to construct an underground structure of the lower story. According to the constitution, a plural-story underground structure can be easily constructed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for constructing multi-story basements and other underground structures.

[Background Art] In recent years, with the rise in land prices, there has been an increasing trend to construct underground structures such as basements in order to utilize not only the above ground but also the underground space as a living space in order to make effective use of land.

In some cases, when the underground structure is constructed using the panel construction method, the underground structure is constructed by erecting floor panels, wall panels, and roof panels into holes dug in the ground.

[Problems to be Solved by the Invention] The above-mentioned conventional underground structures have a problem in that only underground-story underground structures have been put into practical use.

The present invention has been made in order to solve the above-mentioned conventional problems, and aims to provide a method for constructing a multi-story underground structure that can easily and quickly construct a multi-story underground structure. This is an issue to be addressed.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a method for forming the floor and roof (ceiling) of each floor by attaching and fixing a face material to the surface of a panel frame made of shaped steel. Consisting floor panels and m! Forming a large wall panel (wall panel, ceiling panel) and a wall section of multiple stories in height, and furthermore, laying a floor panel forming the floor section of the lower floor at the bottom of a hole dug in the ground, A wall panel is erected and fixed on the floor panel, and a roof panel (ceiling panel) constituting the roof section (ceiling section) of the lower floor is erected and fixed in the middle part of the wall panel to create an underground structure on the lower floor. It is characterized by constructing an underground structure for the upper floor by constructing a roof panel (ceiling panel) that constitutes the roof (ceiling) of the upper floor at the upper end of the wall panel and fixing it. .

[Example] Hereinafter, the present invention will be described in detail based on drawings showing examples.

For example, as shown in FIGS. 1 to 6, a steel plate or other face material 2 is stretched on the surface of a panel frame 1 made of angle steel, channel steel, or other type steel, and is fixed by welding. The floor panels 3 and roof panels (ceiling panels) 4 that constitute the floors and roofs of each floor of the underground structure, and the walls of multiple stories in height (spanning the entire height of the underground structure with multiple stories) A large wall panel 5 constituting the wall section) is formed, and furthermore, floor panels 3.3, . Then, wall panels 5.5, . . . are erected on the floor panels 3.3, .
The wall panel 5 is secured by tightening with bolts 6 and nuts 7.
．． A roof panel (ceiling panel) 4 constituting the roof section (ceiling section) of the lower floor is installed in the middle part of the lower floor section 6, and is secured with bolts 6 and nuts 7 to construct the underground structure on the lower floor and to connect the wall. A roof panel (ceiling panel) 4 constituting the roof (ceiling) of the upper floor is installed on the upper end of the panel 5.5, and is tightened and fixed with bolts 6 and nuts 7 to secure the underground structure on the upper floor. The present invention relates to a method of constructing a multi-story underground structure characterized by:

In addition, FIGS. 1 to 3 show that the roof panel (ceiling panel) 4 on the lower floor is fitted between the wall panels 5 and 5, and the roof panel (ceiling panel) 4 on the upper floor is fitted between the wall panels 6. .6 shows an example in which it is placed on the upper end and constructed, and Figures 4 and 5
The figure shows an embodiment in which a lower floor roof panel (ceiling panel) 4 and an upper floor roof panel (ceiling panel) 4 are both fitted between wall panels 5.5.

In addition, in the present invention, adjacent floor panels 3.3 comrades,
Roof panel (ceiling panel) 4.4 Comrades and wall panel 5
．． When connecting and fixing 5 comrades, for example, as shown in FIG. , bolts 6 and nuts 7 may be used.

Also, the reason why 4 is described as a roof panel (ceiling panel) is that depending on the installation position of the panel, it can act as a roof panel or a ceiling panel.For example, in a multi-story underground structure, the most The upper panel acts as a roof panel for the top floor, and the other panels act as ceiling panels for the lower floor.

Further, in the embodiments of the present invention shown in FIGS. 1 to 5, a two-story underground structure is illustrated, but it goes without saying that an underground structure of three or more stories can also be constructed in the same manner as in the above embodiments.

[Effects of the Invention] As described above, the present invention provides a floor panel and a roof panel that constitute the floor and roof (ceiling) of each floor by stretching and fixing a face material to the surface of a panel frame made of shaped steel. (ceiling panels) and large wall panels that make up the walls of multiple stories in height.Furthermore, floor panels that make up the floors of the lower floors are laid at the bottom of holes dug in the ground. A wall panel is erected and fixed on the floor panel, and the lower floor roof part (
Erection of the roof panels (ceiling panels) that make up the ceiling section,
At the same time, a roof panel (ceiling panel) that constitutes the roof (ceiling) of the upper floor is erected on the upper end of the wall panel, and is fixed to construct the underground structure on the upper floor. Since we are constructing a multi-story underground structure, the steel molds that make up the panel frame will have sufficient strength as a bridge for the underground structure, and the floor panels, wall panels, and roof panels (ceiling panels) will be erected in sequence. Multi-story underground structures can be constructed easily and quickly by simply fixing them together.In addition, since the wall panels are formed of large wall panels with a height dimension of multiple stories, it is possible to easily and quickly construct underground structures with multiple floors. It is extremely advantageous in terms of strength and work efficiency.
