DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for constructing a basement or other underground structure.

[0002]

2. Description of the Related Art Conventionally, when constructing a basement or another underground structure, a hole for forming an underground structure is dug in the ground,
In order to prevent landslides on the inner peripheral surface of the underground building forming hole, two form panels are juxtaposed at intervals on the inner peripheral surface, and a horizontal reinforcing bar made of reinforcing steel is provided between the form panels. After arranging the vertical bars and laying concrete to perform the retaining work, the pillars of the underground building are erected near the side wall of the hole for forming the underground structure and the bottom of the hole for forming the underground structure is formed. A floor material is formed by laying a floor material, a horizontal bar and a vertical bar are laid between the pillars, and form panels are arranged side by side on both sides of the reinforcing bar at intervals. Concrete is cast between the panels to form a wall foundation, and thereafter, according to a conventional method, a roof is stretched at the upper end opening of the wall foundation, a floor finishing material is stretched on the floor foundation, and the wall foundation is stretched on the wall foundation. The underground building is being constructed with wall finishing materials.

[0003]

In the above-mentioned prior art, it is troublesome to arrange the horizontal and vertical bars on the inner peripheral surface of the hole for forming the underground structure and to cast concrete to perform the mountain retaining work. In addition, there is a problem that the horizontal and vertical reinforcing bars and concrete used in the retaining work are required separately and irrespective of the constituent materials of the underground structure, and are economically uneconomical. In addition, there was a problem that it was troublesome to quickly and reliably arrange the horizontal and vertical bars between the pillars of the underground structure.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. By using the groundwork of an underground structure as a mountain retaining material, it is possible to omit troublesome mountain retaining work and to reduce the cost. It is an object of the present invention to provide a method of constructing an underground structure capable of quickly and reliably arranging horizontal and vertical reinforcing bars without waste of material and being extremely rational. Things.

[0005]

According to the present invention, in order to solve the above-mentioned problems, a hole for forming an underground structure is formed in the ground, and a steel pillar is provided near a side wall of the hole for forming an underground structure. At the same time, a floor material is laid at the bottom of the hole for forming an underground structure to form a floor base, and the floor material is spaced at regular intervals in the longitudinal direction.
And Haisuji the vertical stripe material by the intersection with the lateral muscle material while bridging the lateral stripe material muscle material receiving piece causing collision set by integrally welded steel pieces Te, mold spaced on opposite sides of該配muscle portion It is characterized in that panels are juxtaposed and concrete is poured between the formwork panels to form a wall foundation that also serves as a mountain retaining.

Formwork panel 8 made of plywood, synthetic resin plate, steel plate, mesh sheet, etc. lined with a heat insulating material such as foamed polystyrene or foamed polyurethane at intervals on both sides of the reinforcing bar. , 8 are arranged side by side, and concrete 9 is cast between the formwork panels 8, 8 to form a wall foundation 10 which also serves as a mountain retaining structure.

A floor material 3 is provided at the bottom of the hole for forming an underground structure.
In the case where the floor base 4 is formed by laying
As shown in the figure, similar to the case of forming the wall foundation 10, the horizontal reinforcing members 6, 6,... And the vertical reinforcing members 7, 7,. The base material 4 is formed by casting and laying a floor material 3 made of steel, or a steel panel (H) is formed at the bottom of the hole for forming an underground structure.
A steel sheet is stretched on one or both sides of a panel frame made of a shape steel such as a shape steel, a U-shaped steel, an L-shape steel, an I-shape steel, and a floor material made of a panel integrated by welding is laid to lay a floor base. May be formed.

In FIG. 1 and FIG. 2, reference numeral 11 denotes an L-shaped steel for supporting the formwork panels 8 at the corners of the underground structure;
A corner angle 12 is made of an L-shaped metal material or the like, and 12 is a corner angle receiver made of a die steel piece, a metal box piece, or the like on which the corner angle 11 is placed, and a lower end of the corner angle 11 is placed on the corner angle receiver 12. Place and weld.

In FIG. 1, 13 is a split stone, 14 is a floor building such as a pull-up or joist of a ground building to be mounted and fixed on an underground structure, and 15 is a ground building standing on the floor building 14. Pillar material.

In FIG. 1, reference numeral 16 denotes a joint reinforcing bar piece composed of a reinforcing bar piece, an iron bar piece, and the like used for connecting the horizontal reinforcing bars 6, 6, the vertical reinforcing bars 7, 7, and the like. Vertical streaks 7,
