DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corner panel arranged at a corner of an underground structure constructed by a plurality of panels.

[0002]

2. Description of the Related Art Recently, as a simple underground structure, there is one formed by three-dimensionally assembling a plurality of steel panels.

FIG. 3 shows an example thereof. The underground structure of this figure has a corner panel 1 in which two steel panels are pre-welded to form a corner, and the corner panel 1 is provided between the corner panel 1. The side wall panel 2 located, the ceiling panel 3 which is suspended above the corner panel 1 or the side wall panel 2 to form a ceiling, and the floor which is horizontally extended below the corner panel 1 or below the side wall panel 2 The floor panel 4 forming a part, and these are assembled by being fixed to each other at the site where the structure is installed.

[0004]

By the way, when a heavy building such as a reinforced building is constructed on the upper part of the underground structure, the corner of the underground structure is connected to the upper structure. Foundation columns will be placed.

In the case of the underground structure as shown in FIG. 3, through holes for columns are formed in the corners of the ceiling panel 3 and the floor panel 4 located above and below the corner panel, and the through holes are formed in the through holes. After penetrating the stanchion, welding is performed, and the work such as sealing the welded part for waterproofing is carried out.

Since such work is performed after assembling the panels of the underground structure, it must be performed on site, and the pillars are often complicated in shape such as shaped steel, which is very troublesome. Yes, so work efficiency is not good.

On the other hand, as shown in FIG. 4, the pillar 5a is arranged in the underground structure, and another pillar 5b other than the pillar 5a is arranged on the ceiling panel 3 and indirectly through the ceiling panel 3. If the pillars 5a and 5b are connected, the through hole is not necessary and the above problem can be solved. On the other hand, since the pillars 5a and 5b are indirectly connected, there is a problem that the structure is unstable.

The present invention was devised in view of the above problems of the prior art, and it is an object of the present invention to provide a corner panel capable of eliminating the complexity of the arrangement of columns in the field.

[0009]

Therefore, a corner panel of an underground structure according to the present invention is a corner panel forming an underground structure, and a plurality of other corner panels are provided above and below the corner side. It is characterized in that an auxiliary panel that forms a part of the ceiling portion and the floor portion of the structure together with the ceiling panel and the floor panel is fixed in advance.

[0010]

With respect to the corner panel forming the underground structure, it suffices that the ends of the two panels be fixed (for example, welded), and this work can be performed not in the field but in a factory, as in the conventional case. It is also possible to transport the formed material to the site. This also applies to the work of fixing (for example, welding) auxiliary panels that form a part of the ceiling and floor of the structure together with other ceiling panels and floor panels above and below the corner of the corner panel. It is also possible to carry such corner panels.

Further, the work of fixing the columns to the auxiliary panels fixed to the upper and lower sides can be easily performed in the factory, and the corner panels can be transported. In particular, since the corner panel is smaller in size than the completed underground structure, it is easy to pierce the auxiliary panel and fix the auxiliary panel.

[0012] The corner panel thus formed, to which the columns have been fixed, is brought to the installation site, and other corner panels (however, when it is necessary to fix the columns to all the corner panels) Is a fixed corner panel only), a side wall panel, a ceiling panel and a floor panel in which a notch for the area of the auxiliary panel is formed, and the ceiling panel and the floor panel together with the ceiling panel. And, by fixing other ceiling panels and floor panels forming the floor, the underground structure to which the columns are fixed is assembled. That is, at the site, almost only the work of fixing the panels together completes the underground structure to which the columns are fixed.

[0013]

An embodiment of the present invention will be described with reference to the drawings. It should be understood that the present invention is not limited to the examples below.

FIG. 1 shows an example of a corner panel used in an underground structure 60 in which columns 50 are arranged in all four corners. In the figure, 10 is a corner panel, 20 is a side wall panel, 30 and 31 are ceiling panels, and 40 and 41 are floor panels, which are joined by a fixing member 70 via a sealing member to form an underground structure 60. To be done. These panels are made of steel and 50 are stakes made of H-section steel.

The feature of this embodiment is the corner panel 10 and the ceiling panel 30 and the floor panel 40 on the end side of the ceiling panel and the floor panel. That is, the side wall panel 20 and the central ceiling panel 31 and the floor panel 41 among the ceiling panel and the floor panel are the same as the conventional ones, and the description thereof will be omitted.

The corner panel 10 is formed by welding the ends of two steel panels, and the auxiliary panels 11 are previously welded to the upper and lower sides of the corners.

The auxiliary panel 11 has corner panels on both sides.
10 When the ceiling panel 30 or floor panel 40 on the end side, which has a shorter side length than the top and bottom sides, is suspended or laterally suspended, forms the ceiling or floor at the end of the underground structure 60 together with it. . Therefore, in the ceiling panel 30 and the floor panel 40, the auxiliary panel 11 cutouts are formed in the portions that become the ceiling corners or the floor corners of the underground structure 60.

The corner panel 10 as described above is completed only by welding the two steel panels and the auxiliary panel 11 to each other, so that the forming work is not required to be performed at the structure installation site. This can also be done in a factory, for example. Since the size of the underground structure 60 is smaller than that of the main body of the underground structure 60, it can be transported in the shape after being formed.

In this embodiment, the support column 50 is penetrated through the upper and lower auxiliary panels 11 of the corner panel 10 and fixed by welding, and the welded portion is sealed. Since the corner panel 10 is compact as described above, the work of fixing the support column 50 can also be performed in a place such as a factory where the work can be performed easily, and can be sufficiently transported.

That is, in the corner panel 10 of this embodiment,
Since the fixing work of the support column 50 can be performed in a factory or the like, the corner panel 10 after fixing the support column 50 is transported to the site of the structure installation, and in the field work, the corner panel 10 and other panels are The installation work of the underground structure 60 will be completed only by the fixing work and the fixing work to the foundation base (not shown) at the lower part of the pillar 50. Therefore, in the underground structure 60 shown in FIG. 1, it is possible to eliminate the work of fixing the support column 50, which has been very complicated in the past and has been performed after the panel is assembled. Since the fixing work can be performed, the efficiency of the installation work of the underground structure 60 is significantly improved.

There are various other possible modes of fixing the columns 50 to the auxiliary panel 11, and the structure shown in FIG. 2 can be cited as an example. In the structure shown in FIG. 2, the pillar 50 is penetrated and welded to the upper auxiliary panel 11, but on the lower auxiliary panel 11 side, the base fixing base plate 51 is fixed to the pillar 50.
The base plate 51 is fixed to the auxiliary panel 11. The fixing to the base is performed by screwing the base plate 51 with anchor bolts 52 extending from the base.

[0022]

As described above, according to the corner panel according to the present invention, the work of fixing the support can be performed most easily in the work, for example, in a factory, so that the corner after the support is fixed. The partial panel is transported to the site of the structure installation, and in the field work, the installation work of the underground structure is almost completed only by the fixing work of the corner panel and other panels. Therefore, it is possible to eliminate the work of fixing the columns, which has been very complicated before and after the assembly of the panel, and can perform the work of fixing in the factory where it is the easiest to work. The work efficiency will be greatly improved.
