A hollow rectangular parallelepiped shape formed by covering the periphery of a frame structure formed by horizontally connecting the upper ends of each column with a plurality of beam members with an armor plate composed of a ceiling armor plate and a side armor plate Concerning container structure.

FIG. 11 shows a conventional example of a bulletproof residential container that is installed in a base or the like that may receive a shell from above and accommodates personnel.
In FIG. 11, 100 is a hollow rectangular parallelepiped container.
Reference numeral 1 denotes a base of the container 100, which is installed on the ground and has a floor plate 1a placed and fixed on the upper part of the floor frame. 02 is a column vertically provided at the four corners on the base 1, 013 is a longitudinal beam member that connects the upper ends of the columns 02 horizontally and longitudinally, and 014 is the upper end of the column 02. It is a width direction beam member which connects each other horizontally and in the width direction.

  The upper part of the frame structure composed of the base 1, the four support columns, the longitudinal beam member 013, the width direction beam member 014 and the like is covered with a ceiling armor plate 010, and the periphery of the side portion of the frame structure is in the longitudinal direction.

JP-A-2005-241183

In the conventional hollow rectangular parallelepiped container 100 as shown in FIG. 11, when the shell 101 hits the ceiling armor plate 010 covering the upper part of the frame structure as indicated by the arrow W (10a is a collision part). The impact force of the shell 101 is supported on the base 1 via the ceiling armor plate 010, the longitudinal beam member 013 and the width direction beam member 014, the four struts 02, and the side armor plates 011 and 012.
Therefore, in the container 100 having the frame structure and the armor plate having such a configuration, the ceiling armor plate 010 that is the impact force transmitting member, the four support columns 02, the longitudinal beam member 013, and the width direction beam member 014. Since the side armor plates 011 and 012 and the like are configured as a highly rigid structure having a small shock-absorbing function against the impact force, the cross-sectional area of the impact force transmission member may be used to make the structure capable of withstanding a large impact force. And it is necessary to increase the size by increasing the section modulus. For this reason, in such a container 100, the weight of the container 100 is increased, which makes it difficult to transfer and install, and increases the material cost of the container 100.

Further, the technique of Patent Document 1 includes a bulletproof plate for absorbing an impact force caused by a direct impact of a shell, and an elastic support mechanism using a spring that elastically supports the bulletproof plate. It is possible to suppress to some extent the increase in the size of the frame structure and the armor plate, which are impact force transmission members, in order to obtain a structure that can withstand the load. However, in the technique of Patent Document 1, it is necessary to provide a bulletproof plate that is an impact force absorbing member and an elastic support mechanism thereof, which increases the number of parts of the container and increases the impact force absorbing member. Assembling man-hours associated with mounting increase, resulting in high costs.
There are problems to be solved.

  In view of the problems of the prior art, the present invention reduces the weight of the frame structure and armor plate constituting the container as a structure capable of absorbing the impact force due to the direct impact of the shell without installing a special impact force absorbing mechanism. The object of the present invention is to provide a container structure that is miniaturized and has improved transportability and installation workability.

The present invention achieves such an object, and is a quadrangular base that is installed on the ground and has a floor plate placed on the upper surface side, columns that are vertically installed at four corners on the base, A hollow rectangular parallelepiped shape formed by covering the periphery of a frame structure composed of a plurality of beam members that connect the upper ends of the columns in the horizontal direction with an armor plate composed of a ceiling armor plate and a side armor plate The beam member is formed by joining an upper member and a lower member made of a square pipe formed in a square hollow cross section and joining the outer peripheral surfaces thereof in a vertical direction, and the upper member is a lower member. It is configured to be lower in rigidity, and configured to transmit a load including an impact load acting on the ceiling armor plate from the ceiling armor plate to the lower member via the upper member of the beam member. (Claim 1).
Here, the specific means for configuring the upper member to be lower in rigidity than the lower member is preferably a means for making the compression cross-sectional area of the upper member smaller than the compression cross-sectional area of the lower member.

According to this invention, when the shell hits directly on the ceiling armor plate covering the upper part of the frame structure, the first step of absorption of the impact force is performed by bending the ceiling armor plate by the impact force of the shell. The impact force after the first stage buffering is transmitted from the ceiling armor plate to the upper member on the low rigidity side of the beam member made of a square pipe, and the upper member is compressed and deformed in a direction perpendicular to the cross section. The second stage of absorption of the impact force is performed.
Further, the impact force after the second stage buffering is transmitted to the lower member on the high rigidity side of the beam member made of the square pipe, and the lower member is compressed and deformed in a direction perpendicular to the cross section, thereby the impact force. The third stage absorption is performed.
The impact force of the direct impact of the cannonball is attenuated by absorbing and absorbing in three stages, and is transmitted to the base fixed on the ground via the four struts and the side armor plates. Supported by a stand.

Therefore, according to this invention, the impact force due to the direct impact of the shell can be applied to the bending of the ceiling armor plate, the compression deformation in the direction perpendicular to the cross section of the upper member on the low rigidity side made of a square pipe, the lower part on the high rigidity side made of a square pipe Since it is attenuated by three stages of buffer deformation and absorption at right angles to the cross section of the member, it is attenuated by absorption and transmitted to the strut and side armor plate, so the compression cross-sectional area of the impact force transmission member such as strut and side armor plate is Even if it is made small, the impact load attenuated and reduced by the three stages of buffering and absorption as described above can be sufficiently supported without causing excessive deformation of the impact force transmission member.
This makes it possible to downsize impact force transmission members such as support columns and side armor plates compared to conventional ones, reducing the weight of the container, and improving the transportability and installation workability of the container. It can be improved, and the material cost can be reduced by downsizing the container.

  In addition, the impact force absorbing member that attenuates the impact force due to the direct impact of the shell by the three-stage buffering and absorption as described above is used for the ceiling armor plate that is the strength member of the container, the upper member on the low rigidity side, and the upper member on the high rigidity side. Since the lower member is also used, it is not necessary to install a special impact force absorbing member such as the bulletproof plate and its elastic support mechanism in Patent Document 1 (Japanese Patent Laid-Open No. 2005-241183). As a result, a container having high impact resistance can be obtained without increasing the number of parts and assembly man-hours of the container and increasing the cost.

In this invention, preferably, the side armor plate is welded at its upper end to the lower surface of the beam member and its lower end is welded to the upper surface of the base so that a load applied to the beam member is applied to the beam member. A member can be transmitted to the base via the side armor plate (Claim 2).
With this configuration, a load such as an impact force applied to the beam member passes through the side armor plate from the welded joint between the lower surface of the beam member and the side armor plate, and the lower end portion of the side armor plate Since it is transmitted to the base through the welded joint with the upper surface of the base and is supported by the base, the side armor plate functions as a strength member that supports and transmits loads such as impact force. Since the load such as impact force can be supported by the four support columns and the side armor plates, the support columns can be downsized.

In this invention, preferably, the base is made of a channel steel material having a U-shaped cross section, and a spacer fixed to the lower surface of the base is interposed between the lower surface of the base and the ground. (Claim 3).
With this configuration, the load applied to the base is transmitted to the ground via the spacer fixed to the lower surface of the base, so that the contact surface pressure is reduced by the installation of the spacer, and the container is stably grounded. Can be installed on top.

  The present invention also provides a quadrangular base that is installed on the ground and has a floor plate placed on the upper surface, columns that are vertically installed at four corners on the base, and upper ends of the columns. A hollow rectangular parallelepiped container formed by covering the periphery of a frame structure composed of a plurality of beam members connected in the horizontal direction with an armor plate made of a ceiling armor plate and a side armor plate, The beam member is fixed to the upper end portion of the support column and includes a connecting member formed in a solid square section connecting the ceiling armor plate and the support column, and a lower surface of the base unit is provided at a lower portion of the base unit. The side armor plate has an upper end fixed to the beam member and a lower end fixed to the upper surface of the spacer. Item 4).

According to this invention, after the impact force due to the direct impact of the shell is absorbed by the deflection of the ceiling armor plate, the damping impact force is increased with the solid square cross-section connecting member having high rigidity. Since it is mainly received by the four struts and transmitted to the base and the spacer, the upper impact force from the side of the ceiling armor plate applied to the side armor plate is reduced, and the thickness of the side armor plate is increased It is enough to have a thickness that can handle a side load such as a direct hit of a piece from the side without adding impact force.
As a result, the thickness of the side armor plate can be made the minimum thickness that can handle the lateral load, the weight of the container can be reduced, and the transportability and installation workability of the container can be improved. At the same time, material costs can be reduced by downsizing the container.

  In addition, since the spacer fixed to the lower surface of the base is interposed between the lower surface of the base and the ground, the impact force is transmitted to the ground via the spacer fixed to the lower surface of the base. Thus, the contact surface pressure is reduced by the installation of the spacer, and the container can be stably installed on the ground.

  In this invention, preferably, a side reinforcing plate made of a steel plate having an upper end fixed to the lower portion of the beam member and a lower end fixed to the upper surface of the base is provided inside the side armor plate. (Claim 5).

  If comprised in this way, since load, such as an impact force applied to a beam member, can be transmitted to a base also through a side reinforcement board which consists of a steel plate arranged in parallel with a side armor board, the side reinforcement board It functions as a strength member that cooperates with the side armor plate to support and transmit loads such as impact force, and thereby, loads such as impact force are supported by four columns, side armor plates, and side reinforcement plates. These members can be miniaturized.

  According to the present invention, the impact force due to the direct impact of the shell is reduced by three stages of buffer deformation, compression deformation in a direction perpendicular to the cross section of the lower rigid member and the rigid lower member made of a square pipe. Even if the compression cross-sectional area of the impact force transmission member such as the support column and the side armor plate is made small by being attenuated by absorption and transmitted to the support column and the side armor plate, it is attenuated by the three stages of buffering and absorption. It is possible to fully support the impact load that has been reduced without causing excessive deformation of the impact force transmission member. It is possible to reduce the size of the member, reduce the weight of the container, improve the transportability and installation workability of the container, and reduce the material cost by reducing the size of the container.

  In addition, the impact force absorbing member that attenuates the impact force due to the direct impact of the shell by the three-stage buffering and absorption as described above is used for the ceiling armor plate that is the strength member of the container, the upper member on the low rigidity side, and the upper member on the high rigidity side. Since it is also used as a lower member, it is not necessary to install a special shock absorbing member as in the prior art, and it is impact resistant without increasing the number of parts and assembly man-hours of the container and increasing the cost. High container is obtained.

May be opened).

As shown in FIGS. 3 and 4, the longitudinal beam member 13 and the width beam member 14 are formed on the outer peripheral lower surface of the upper member 4 made of a square pipe formed in a square hollow cross section and in the square hollow cross section. The outer peripheral upper surface of the lower member 5 made of a square pipe is welded and joined in a vertical direction via a connecting piece 4a.
The longitudinal beam member 13 and the width beam member 14 have a compression cross-sectional area of the upper member 4, that is, a cross-sectional area in the direction in which the impact force W is applied by the shell 101 as shown in FIGS. Thus, the upper member 4 is configured to have a lower rigidity than the lower member 5 in the impact force W direction.
Further, as shown in FIG. 3, the ceiling armor plate 10 is fixed to the upper surface of the upper member 4 by a plurality of bolts 10a.

Further, in the first embodiment, as shown in FIG. 3, the side armor plate 11 is welded and joined in such a form that the upper end portion is abutted against the lower surface of the longitudinal beam member 13 via the connecting piece 20a. The lower end portion is welded and joined in a form that abuts the upper surface of the base 1 via the connecting piece 20b. S is a butt weld joint.

Although not shown, the width direction beam member 14, the side armor plate 12, and the base 1 are also configured in the same connection form as in FIG. Reference numeral 21 denotes a heat insulating material fixed to the inner surface side of the side armor plate 11.

  If comprised in this way, the impact force W which acted on the said longitudinal beam member 13 (or the said width direction beam member 14) will make the lower surface and side armor board of this longitudinal direction beam member 13 (the width direction beam member 14). 11 (or side armor plate 12) through the side armor plate 11 (12) from the weld joint S to the base armor plate 12, and through the weld joint S between the lower end portion of the side armor plate 11 and the upper surface of the base 1. Since it is transmitted to the base 1 and supported by the base 1, the side armor plate 11 (12) functions as a strength member that supports and transmits the impact force W, whereby four impact forces W are provided. Can be supported by the column 2 and the side armor plate 11 (12), and the column 2 can be downsized.

Further, in the first embodiment, as shown in FIG. 3, the base 1 is made of channel steel material having a U-shaped cross section, and the base 1 is interposed between the lower surface of the base 1 and the ground 23. A spacer 22 fixed on the lower surface of the table 1 is interposed.
If comprised in this way, since the impact force W added to this base 1 will be transmitted to the ground 23 via the spacer 22 fixed to the lower surface of the base 1, the contact surface pressure will fall by installation of the said spacer 22. Thus, the container 100 can be stably installed on the ground 23.

When the shell 101 hits directly as indicated by the arrow W as shown in FIG. 1 on the ceiling armor plate 10 covering the upper portion of the frame structure of the residential container 100 configured as described above (10a is a collision portion), When the ceiling armor plate 10 is bent by the impact force of the cannonball 101, the first stage of absorption of the impact force is performed.

Further, the shock force W after the second stage buffering is transmitted to the lower member 5 composed of a square pipe on the high-rigid side having a large compression cross-sectional area in the acting direction of the impact force W via the connecting piece 4a. When the compression sectional area of the lower member 5 is compressed in the vertical direction (acts on the compression sectional area) and deformed, the impact force W is absorbed in the third stage.
The impact force W due to the direct impact of the shell is attenuated by absorbing and absorbing the three stages of the first stage, the second stage, and the third stage as described above, and the four struts 2 and the side armor plate. 11 and 12 are transmitted to the base 1 fixed on the ground 23 via the spacer 22 and supported by the base 1.

Therefore, according to the first embodiment, the impact force W caused by the direct hit of the cannonball 101 is applied to the bending of the ceiling armor plate 10, compression deformation in the direction perpendicular to the cross section of the lower rigid upper member 4 made of a square pipe, Since it is attenuated by the three-stage buffering and absorption of the compression deformation in the direction perpendicular to the cross section of the lower rigid member 5 on the high rigidity side, it is transmitted to the column 2 and the side armor plates 11 and 12, so Even if the compression cross-sectional area of the impact force transmission member such as the plates 11 and 12 is reduced, the impact force W attenuated and reduced by the three stages of buffering and absorption as described above is excessive. Sufficient support is possible without causing deformation.
Thereby, it becomes possible to reduce the size of the impact force transmission member such as the support column 2 and the side armor plates 11 and 12 as compared with the conventional one, and the weight of the container 100 can be reduced. The transportability and installation workability of the container can be improved, and the material cost can be reduced by downsizing the container 100.

  Further, the impact force absorbing member that attenuates the impact force W caused by the direct impact of the cannonball 101 by the above-described three-stage buffering and absorption is used as the ceiling armor plate 10 that is the strength member of the container 100 and the upper member 4 on the low rigidity side.
