Next, as shown in FIG. 9, the panel member 5 is disposed between the upper and lower beam members 12 and 14 on the side surface and between the upper and lower beam members 11 and 13 on the end surface, and the engaging metal fitting 2 is similarly formed.
7 and further, as shown in FIG. 10, if the panel member 5 is arranged over the upper wall surface, that is, between the fourth beam members 14, 14, and fixed by the engagement fitting 27, as shown in FIG. In addition, a small number of members (4 types of beams, 1 column
Type and panel material), and the structure 1 can be safely, easily and quickly assembled underground.

Further, in assembling, after assembling the upper wall frame and the bottom wall frame, the panel material is attached, so that safer, quicker and more accurate work becomes possible. The assembling work at the place is also facilitated.

According to the structure of this structure, each wall frame has a role of connecting the panel members, and all external forces are supported only by the panel members. Therefore, for example, the external force from the top is the panel material on the upper wall → the fourth beam material → the panel material on the side wall surface → the second beam material → the panel material on the bottom wall surface. Panel material → 2nd and 4th
Beam material → panel material on the upper bottom wall → second and fourth beam material on the other → panel material on the other side wall is transmitted to the ground respectively,
A bending force and an axial force act on the panel material, and a compressive force acts on the beam material.

When this structure is buried in the soil,
Since this structure is supported by the surrounding earth pressure, in a normal static equilibrium state, a diamond-like crushing force does not act. However, when an impact load due to, for example, an explosion is applied, deformation such as crushing the structure occurs. At this time, if the structure is rigid,
A large force acts on each of the engagement connecting portions between the beam member and the panel member, and between the column member and the panel member, so that they are broken. However, as described above, since the beam, the column, and the panel are hollow, when a large force is applied, the members are prevented from being deformed and damaged, and therefore, are not affected by an impact. Has high strength.

Further, in this embodiment, as shown in FIGS. 3 and 4, the pressure receiving area (contact area) of each beam member with respect to the panel member is set to be substantially equal to the entire end area of the panel member. Therefore, as shown in FIG. 12, for example, only about half the area of the end portion of the panel material 31 is reduced by the beam material 32.
As compared to the case where the beam is not brought into contact with the beam, the rotational force, that is, the torsional force does not act, and therefore, only the compressive force acts on the beam. Therefore, it is possible to reduce the strength of the beam and reduce the weight. it can.

Next, a second embodiment of the present invention will be described with reference to FIGS. The second embodiment differs from the first embodiment in the engagement members provided on the beam members and the column members. Therefore, the following description focuses on this portion.

That is, for example, a rectangular engaging hole 62 is formed at the center of the end of the first beam 61 forming the bottom wall frame 51.
a, and a step (engaging member) 62 having a rectangular parallelepiped guide projection 62b protruding from the left and right sides of the engagement hole 62a.

At the end of the second beam member 63, an engaging recess 64a corresponding to half of the engaging hole portion 62a of the first beam member 61 is formed at the tip thereof, and at the inner position, the engaging recess 64a is formed. A projecting portion (engaging tool) 64 having a positioning hole 64b that is detachable from one guide projection 62b provided on the step portion 62 of one beam member 61 is provided.

Further, as shown in FIG. 15, an engaging hole 62a provided in the first beam 61 is formed at an end of the pillar 66.
In addition, an engaging projection 67a that can be inserted into and removed from the insertion hole 65 formed by the engaging recess 64a of the pair of second beam members 63, and positioning hole portions provided on both sides of the engaging projection 67a. 64b is provided with an engaging member 67 comprising a positioning projection 67b which can be inserted and removed.

In the above configuration, when assembling the bottom wall frame 51, as shown in FIGS.
Two second beam members 63 are placed on one step 62. That is, the positioning holes 64b of each of the second beam members 63 are engaged with the two guide projections 62b of the first beam member 61, and then, as shown in FIGS. The engaging projection 67a and the positioning projection 67b of the section may be inserted into the insertion hole 65 and the positioning hole 64b, respectively.

As described above, the first beam member 61 is attached to the second beam member 63.
Since the positioning holes 64b are engaged and guided by the guide projections 62b, the assembling work can be performed easily and quickly. Further, since the positioning projections 67b provided on the column member 66 are also inserted into the positioning holes 64b of the second beam members 63 on both sides, these members are firmly connected to each other.

FIGS. 17 to 20 show a procedure for assembling the corner portion of the bottom wall frame 51. FIG. Since the procedure is the same as above, the description is omitted, but the end of the first beam 61 is
Only one guide protrusion 62b is provided, and a guide recess 62c for guiding one positioning protrusion 67b on the column 66 side is provided. Note that FIG.
17 is a perspective view of an end portion of the first beam member 61, as viewed in the direction of arrows CC in FIG.
