Description

[Detailed Description of the Invention] This method relates to a method for constructing underground structures and buildings with basements. There is a basement construction method that is characterized by the installation of panels (called panels).

This invention is a method of constructing a basement in which an underground section is constructed by excavating the ground, erecting a steel frame on the foundation, and then attaching ready-made steel panels to the frame. A steel column with a bottom plate surrounded by side walls.

A steel panel for mounting, which is formed in the shape of a box and has a flange formed on the side wall, is mounted so that its bottom plate is perpendicular to the steel column and in contact with the flange formed on the side wall, and then the copper panel for mounting is attached. A basement section is constructed by attaching a steel wall panel or a steel floor panel frame to the side wall or flange of the basement. The construction method according to the present invention will be explained below with reference to the accompanying drawings.

First, excavate the ground A to the required depth and create foundation 1.
A steel column 2 serving as a steel frame for the basement portion is erected on top of the column, and the lower part thereof is fixed onto the foundation 1 with anchor bolts 3 and nuts 4.

This steel column 2 is usually made of H-beam steel or the like. Reference numeral 13 denotes a horizontal girder installed horizontally to the steel column 2.

This horizontal girdle 13 supports the steel column 2 so that it is not bent by the earth pressure applied to the side surface of the wall, and also supports the floor of the first floor. Steel wall panels 9 and 10 are installed as walls of the basement, which also serve as earth retainers. This steel wall panel 9,
10 consists of a plate 11 and a plate frame 12. A flat panel as shown in Fig. 7 was used for the middle part between the columns, and an L-shaped panel as shown in Fig. 8 was used for the corner part, and the steel panels 6 for installation fixed to each steel column 2 were used. A plate frame 12 of a steel wall panel is placed on the flange 8 and fixed by inserting bolts into bolt holes provided in the flange 8 and the plate frame 12 and tightening them with nuts. This mounting steel panel 6 is formed into a box shape with a bottom plate surrounded by side walls 7, and a flange 8 is formed on a part of the side wall. The steel frame column 2 at the corner shown in FIG. 10 has a mounting steel panel 6a provided with flanges 8, 8 on two adjacent side walls 7, 7 as shown in FIG. For each steel column 2'', a mounting steel panel 6b having a flange 8 on one side wall 7 as shown in FIG. It is attached so as to be in contact with the formed flange 8, and fixed by conventionally known means such as welding. Incidentally, a mounting copper panel 6c as shown in FIG. 5 is fixed to the steel column 2a inside the basement shown in FIG. 10.

The mounting steel panel fixed to the steel column 2 is either fixed away from the foundation 1 as shown in Figure 2, or placed on the foundation 1 and the steel column 2 is fixed on it as shown in Figure 3. be done.

The steel floor panel 5 is fixed by bringing its plate frame into contact with the side wall of the mounting steel panel 6, inserting bolts into the bolt holes, and tightening them with nuts or the like. The plates 11 of the copper wall panels 9 and 10 directly receive underground lateral pressure and transmit it to the frame 12, and the stress transmitted to the frame 12 is transferred to the steel columns 2 and the steel beams 1.
Tell 3.

The frame 12 is connected to the adjacent frame 1 in order to connect the panels to each other.
2 and a backing 15 with bolts and nuts 16. Although the underground wall body can be constructed only from the above-mentioned steel wall panels, a mortar or concrete layer can be formed on the outer surface to improve corrosion resistance and waterproof properties.

In order to improve the adhesion between mortar or concrete 14 and copper wall panels 9 and 10, steel wall panels 9 and 10 are
Lath is pasted on the outer surface of the concrete, and then mortar or concrete 15 is applied manually while still being sprayed. Along with the construction of the above-mentioned underground section, the above ground floor steel columns 2 will be erected on top of the subway frame columns 2, and the ground floor will be constructed using conventional construction methods, such as attaching wall panels as appropriate.

The method according to the present invention consists of the above-mentioned steps, and can easily erect and assemble underground steel columns, beams, and wall panels. In particular, corner steel columns are provided with corner steel columns. The corner panel can be easily positioned and fixed simply by touching the flange, and then the frame of the panel is brought into contact with the side wall of this corner steel panel and the flange wall, and the bolt insertion hole is inserted into the corner panel. This has the effect of simplifying and speeding up the construction of the underground part by easily attaching the basement frame and wall surface by tightening the nuts to the inserted bolts.
