Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to a method of constructing a basement or other underground 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 a living space in order to make effective use of land. On the other hand, in the case of constructing the above-mentioned underground structure, as shown in FIG. 4, a floor panel 3, a wall panel 4 and a roof which are formed by stretching and fixing a face material 2 on the surface of a panel frame 1 made of shaped steel. The panel 5 is built in a hole to be dug in the ground, and is fastened and fixed with bolts 6 and nuts 7 to form a box-shaped unit 8. Further, a desired number of the box-shaped units 8 are connected, and the bolts 6 and nuts are connected. It is fastened and fixed at 7 to construct an underground structure.

[Problems to be Solved by the Invention]

In the above-mentioned conventional technique, when connecting and fixing the box-shaped units 8 and 8, it is difficult to align the connecting portions of the box-shaped units 8 and 8, and there is a problem that the connecting and fixing work is troublesome. In addition, as shown in FIG. 5, when forming the skip floor by changing the heights of the floor surfaces 9, 9 of the box-shaped units 8, 8, the position of the connecting portion of the box-shaped units 8, 8 There is also a problem that the box-shaped units 8 cannot be smoothly connected and fixed because they cannot be aligned. The present invention has been made to solve the above-mentioned conventional problems, and the work of connecting and fixing the box-shaped units can be performed easily and quickly, and, in addition, the box can be formed even when forming a skip floor. It is an object of the present invention to provide a method for constructing an underground structure capable of smoothly connecting and fixing concrete units.

[Means for Solving the Problems]

MEANS TO SOLVE THE PROBLEM This invention solves the said subject by arranging the surface material on the surface of the panel frame which consists of a shape steel, and building the floor panel, the wall panel, and the roof panel which are fixedly formed in the hole which can be dug in the ground. When forming a box-shaped unit by fixing, and further connecting and fixing a desired number of the box-shaped units to build an underground structure, a joint frame body made of the same shape steel as the panel frame so as to correspond to the panel frame. And the box-shaped units are connected and fixed by interposing a joining frame body between the box-shaped units so as to correspond to the panel frames of the adjacent box-shaped units.

【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. 3, 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. The floor panel 3, the wall panel 4, and the roof panel 5 which are formed by the above are built in the hole (not shown) for excavating on the ground, and the box unit 8 is formed by fastening and fixing with the bolt 6 and the nut 7. Further, when connecting a desired number of the box-shaped units 8 and fastening and fixing with the bolts 6 and the nuts 7 to construct an underground structure, a mountain steel equivalent to the panel frame 1 so as to correspond to the panel frame 1. The joint frame body 10 is formed of grooved steel or other shape steel, and the joint frame body 10 is provided between the box-shaped units 8 and 8 corresponding to the panel frames 1 and 1 of the adjacent box-shaped units 8 and 8. It is characterized in that the box-shaped units 8 and 8 are connected and fixed by interposing Of. It should be noted that FIG. 1 shows an underground two-story underground structure in which the heights of the floors 9 and 9 of the box-shaped units 8 on each floor are formed in the same plane, and FIGS. 2 and 3 show the underground structures of each floor. 2 shows an underground two-story underground structure in which the heights of the floor surfaces 9, 9 of the box-shaped units 8, 8 are stepwise changed to form a skip floor. In addition, as shown in FIGS. 2 and 3, when the box-shaped units 8 on each floor are connected and fixed by changing the heights of the floor surfaces 9, 9, for example, the inside of the joint frame body 10 By connecting the box-shaped units 8 and 8 through the joint frame 10 (peripheral frame) and the middle bar 11 by connecting and fixing the middle bar 11 to the inside, smooth and strong connection,
It is convenient because it can be fixed. Further, when the joining frame body 10 is interposed between the box-shaped units 8 and 8, for example, as shown in FIGS. 1 and 3, the joining frame body 10 is previously attached to one of the box-shaped units 8. The box-shaped unit 8 is formed by integrally welding 12 into the connection opening.
The joint frame body 10 that can be integrally formed with the contact box is brought into contact with the connection opening portion of the other box-shaped unit 8 and fastened and fixed with the bolt 6 and the nut 7, or the joint frame body 10 is fixed as shown in FIG. It suffices that the box-shaped units 8 and 8 are interposed and connected by bolts 6 and nuts 7 so as to be fastened and fixed.

【The invention's effect】

INDUSTRIAL APPLICABILITY As described above, according to the present invention, a surface material is stretched on the surface of a panel frame made of shaped steel, and a floor panel, a wall panel, and a roof panel, which are formed by fixing, are built and fixed in a hole that can be dug in the ground. When a box-shaped unit is formed and a desired number of the box-shaped units are connected and fixed to each other to construct an underground structure, a joint frame body is formed with a shape steel equivalent to the panel frame so as to correspond to the panel frame. At the same time, the box-shaped units are connected and fixed by interposing the joint frame between the box-shaped units so as to correspond to the panel frames of the adjacent box-shaped units. Even with the joint frame,
It can be adjusted and absorbed, so that the work of connecting and fixing the box-shaped units can be done easily and quickly, and in addition, the floor height of the box-shaped units to be connected and fixed can be changed to form a skip floor. Also in this case, the box-shaped units can be smoothly connected and fixed via the joint frame.
