By fixing the panel member 5, the beam members 11 to 14 are firmly connected to each other. Next, the entire assembling procedure will be described with reference to FIGS.

First, as shown in FIG. 6, first and second
The beam members 11 and 12 are assembled into a rectangular shape to form the bottom wall frame 2, and then, as shown in FIG. 7, on the upper surface thereof, that is, between the inner step portions 12b of both the second beam members 12, the panel member. 5 is arranged and fixed by the engagement fitting 27.

With one type and one type of panel material), the structure 1 can be safely, easily and quickly assembled underground.

Further, at the time of assembly, since the panel material is attached after the upper wall frame and the bottom wall frame are assembled, safer, quicker and more accurate work can be performed, and for example, lighting is not sufficient for night work. Assembly work at the place becomes easy.

According to the structure of this structure, each wall frame has a function of connecting the panel members to each other, and all external forces are supported only by the panel members. Therefore, for example, the external force from the upper part is the panel material of the upper wall surface → the fourth beam material → the panel material of the side wall surface → the second beam material → the panel material of the bottom wall surface, and the external force from the side part is the one side wall surface. Panel material → 2nd and 4th
Beam material → panel material on the top and bottom wall surface → second and fourth beam materials on the other side → panel material on the other side wall surface 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 the normal static balance state, the force of crushing into a diamond does not act. However, when an impact load is applied due to, for example, an explosion, the structure is crushed and deformed. At this time, if the structure is rigid, the beam members,
A large force acts on each of the engagement connecting portions of the beam member and the panel member, and between the pillar member and the panel member, and they are damaged. However, as described above, since the beam, column and panel materials are hollow, it is possible to prevent the members from being deformed and damaged when a large force is applied. 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 material is set to be substantially equal to the entire end area of the panel material. Therefore, as shown in FIG. 12, for example, only about half the area of the end portion of the panel material 31 is reduced to the beam material 32.
As compared with the case where the beam is not brought into contact with, the rotational force, that is, the twisting force does not act, and therefore only the compressive force acts on the beam, so that the strength of the beam can be reduced and the weight can be reduced. it can.

Next, a second embodiment of the present invention will be described with reference to FIGS. The second embodiment is different from the first embodiment in that it is an engaging member provided on a beam and a column, and therefore this portion will be focused and described.

That is, for example, at the end portion of the first beam member 61 constituting the bottom wall frame 51, a rectangular engaging hole portion 62 is formed at the center.
A step portion (engagement tool) 62 having a rectangular parallelepiped-shaped guide projection 62b which is formed so as to project at both left and right sides of the engagement hole 62a is provided.

Further, at the end of the second beam member 63, an engaging recess 64a which coincides with half of the engaging hole portion 62a of the first beam member 61 is formed at its tip and at the inner position thereof, the above-mentioned first recess is formed. A protrusion (engagement tool) 64 having a detachable positioning hole 64b is provided on one guide protrusion 62b provided on the stepped portion 62 of the one-beam member 61.

Further, as shown in FIG. 15, an engaging hole portion 62a provided in the first beam member 61 is provided at an end portion of the pillar member 66.
And the engaging projections 67a that can be inserted into and removed from the insertion holes 65 that are formed by the engaging recesses 64a of the pair of second beam members 63, and the positioning hole portions for the beam members 63 on both sides that are provided at both positions. An engaging member 67 including a positioning projection 67b that can be freely inserted and removed is provided in 64b.

In the above structure, when assembling the bottom wall frame 51, as shown in FIGS. 13 and 14, the first beam member 6 is formed.
Two second beam members 63 are placed on one stepped portion 62. That is, the guide holes 62b of the first beam member 61 are engaged with the positioning holes 64b of the respective second beam members 63, and thereafter, as shown in FIGS. The engaging projection 67a and the positioning projection 67b of the part may be inserted into the insertion hole 65 and the positioning hole 64b, respectively.

Thus, the first beam member 61 and the second beam member 63 are
In order to engage with each other, the positioning projection 64b is engaged with and guided by the positioning hole 64b, so that the assembling work can be performed easily and quickly. Further, since the positioning protrusions 67b provided on the pillar members 66 are also inserted into the positioning hole portions 64b of the second beam members 63 on both sides, these members are firmly coupled to each other.

17 to 20 show the procedure for assembling the corner portion of the bottom wall frame 51. Since the procedure is similar to the above, the description thereof is omitted, but at the end of the first beam member 61,
Only one guide protrusion 62b is provided, and a guide recess 62c for guiding one positioning protrusion 67b on the pillar 66 side is provided. Note that FIG.
