As shown in FIG. 2, the test chamber 2 has a main body portion 5 and a door 6. Further, a part of the test chamber 2 is covered with an intermediate member 33 described later.
The test chamber 2 is covered with a top surface, a bottom surface, and four side surfaces by a main body portion 5, a door 6, and an intermediate member 33.
The door 6 is provided in the opening 13 formed on the front surface of the main body 5. In the present embodiment, the door 6 is a double door 6 composed of two door pieces 7. The type of the door 6 is arbitrary, and may be a single door, a sliding door, or an elevating door.

The test chamber 2 of the present embodiment is an assembly panel type test chamber 2, and is a large box body in which a large number of heat insulating panels 10, 11 and 12 are combined as shown in FIG. It is composed of.
The main body portion 5 of the test chamber 2 has a top surface portion 20, a bottom portion 21, and three side surface portions 23, 25, and 26 connecting the top surface portion 20 and a side surface portion 23, 25, and 26 connecting the top surface portion 20 and the bottom portion 21 (FIGS. 2 and 3).

The top surface portion 20 is made by combining a large number of heat insulating panels 10 as shown in FIG. The bottom 21 is also made by combining a large number of heat insulating panels 11. Similarly, the side surface portions 23, 25, and 26 are made by combining the heat insulating panels 12.
The side surfaces of the heat insulating panels 10, 11 and 12 have an uneven shape (not shown), and the uneven portions of the adjacent heat insulating panels 10, 11 and 12 are fitted to each other. Further, joint seals (not shown) are attached to the boundary portions of the heat insulating panels 10, 11 and 12. The insulating panels 10, 11 and 12 are also connected by screws (not shown).

In the present embodiment, the main body portion 5 of the test chamber 2 is largely divided into a bottom body portion 30 constituting the vicinity of the bottom portion 21 and an upper body portion 31 constituting the upper portion side thereof.
That is, as shown in FIG. 2, the bottom body portion 30 is a portion in which a large number of heat insulating panels 11 are combined to form a flat plate that becomes the bottom portion 21, and each member constituting the bottom body portion 30 is a screw (not shown). It is integrally connected by such as.

The upper body 31 is formed by integrally connecting the top surface portion 20 of the test chamber 2 and the side surface portions 23, 25, 26 hanging from the three sides of the top surface portion 20 with screws or the like (not shown).
The upper body 31 has a semi-box shape in which the top surface and three side surfaces are covered with heat insulating panels 10 and 12, and the front surface (opening 13) and the lower surface (opening 15) are open.
In the upper body 31, the heat insulating panels 10 and 12 are connected by screws or the like (not shown). Even if the upper body 31 is removed from the bottom body portion 30, the half-box shape as shown in FIG. 2 is maintained. Further, even if the door 6 is removed, the half-box shape as shown in FIG. 2 is maintained.

In the test chamber 2, the upper body 31 is placed on the bottom body portion 30, and an intermediate member 33 is interposed between the upper body 31.
The intermediate member 33 is a block-shaped heat insulating material.

The gantry 3 is a structure that functions as a load-bearing member, and is a frame that covers the periphery of the test chamber 2.
It should be noted that FIGS. 1 and 2 show the gantry 3 in a simplified manner. The gantry 3 is framed by a plurality of pillars 40 and a beam 41 provided on the upper part of the pillars 40.
The pillars 40 are located around the test chamber 2 and are installed on the floor. The height of the beam 41 is higher than the height of the test chamber 2.
The volume surrounded by the gantry 3 is larger than that of the test chamber 2, and the gantry 3 is a frame body that covers the periphery of the test chamber 2.

Next, the relationship between the gantry 3 and the test room 2 will be described.
In the present embodiment, the test room 2 is divided into a bottom body portion 30 constituting the vicinity of the bottom portion 21 and an upper body portion 31 constituting the upper portion side thereof as described above.
In the present embodiment, the bottom body portion 30 of the test chamber 2 is fixed to the floor surface on which the test chamber 2 is installed.
Apparently, the upper body 31 is placed on the bottom body portion 30 via the intermediate member 33, but the upper body 31 is substantially supported by the gantry 3.

In the present embodiment, mounting ribs 45 are provided in each part of the upper body 31, and the mounting ribs 45 and the gantry 3 are connected by a branch wire material 46. The branch wire 46 is a round bar made of steel, and is stretched around with a certain tension by a turnbuckle or the like (not shown).
Therefore, the upper body 31 is suspended from the beam 41 of the gantry 3 by the branch wire material 46 as shown in FIGS. 1, 3 to 5. The positions of the joints between the branch wire 46 and the gantry 3 are different in FIGS. 1 and 3 to 5, but this difference is merely illustrated as such due to drawing, and is substantially the same. It's not different.

The bottom body portion 30 and the intermediate member 33, and the intermediate member 33 and the upper body 31 are joined by screws or the like (not shown), but most of the weight of the upper body 31 is applied to the intermediate member 33. It is not loaded and is loaded on the outer gantry 3.

Next, the operation of the test room 2 of the present embodiment will be described.
The test room 2 of the present embodiment is designed for the purpose of smoothly replacing the bottom portion 21 in anticipation of damage to the bottom portion 21.

When the bottom 21 of the test chamber 2 is damaged and needs to be replaced, the intermediate member 33 is removed as shown in FIG. 4 (a). For example, the intermediate member 33 may be destroyed with a hammer or the like.
The work of removing the intermediate member 33 may be performed with the door 6 attached to the main body 5.
In the test room 2 of the present embodiment, the upper body 31 apparently rests on the intermediate member 33, but since the weight of the upper body 31 is substantially supported by the gantry 3, the intermediate member 33 is used. Even if it is removed, the upper body 31 remains in a hollow state as shown in FIG. 4A.
Further, even if the upper body 31 is removed from the bottom body portion 30, the original shape is maintained without losing its shape.

By removing the intermediate member 33, the upper body 31 is in a state of floating in the air, and a gap 50 is created between the bottom body portion 30 and the upper body 31.
Further, all the members connecting the bottom body portion 30 and the upper body portion 31 are eliminated. Therefore, the bottom body portion 30 can be pulled out by using the gap 50 as shown in FIG. 4 (b). That is, the bottom body portion 30 can be removed from the original position.
Then, as shown in FIG. 5A, the new bottom body portion 30A is inserted at a position directly below the upper body 31. After that, as shown in FIG. 5B, a new intermediate member 33A is inserted between the bottom body portion 30A and the existing upper body portion 31, and the gap 50 between the two is filled and joined.

In this way, the bottom portion 21 of the test chamber 2 is replaced, the test chamber 2 is reproduced, and the repair of the bottom portion 21 is completed.
According to the test room 2 of the present embodiment, only the bottom portion 21 can be removed and replaced without disassembling the top surface portion 20 and the side surface portions 23, 25, 26, so that the labor is less and the construction period is shorter than before. The construction can be completed at.

In the embodiment described above, the weight of the upper body 31 is substantially supported by the gantry 3, no vertical load is substantially applied to the intermediate member 33, and the intermediate member 33 simply closes the gap 50. It functions as a heat insulating material. Therefore, even if the intermediate member 33 is removed, the upper body 31 maintains its original height and remains hollow, and a gap 50 appears between the bottom body portion 30 and the upper body 31.

Instead of this configuration, the bottom body portion 30 and the upper body 31 may be separated by lifting the upper body 31, and a gap 50 may be formed between the two.

The test chamber 60 shown in FIG. 6 is divided into a bottom body portion 30 and an upper body 31, similarly to the test chamber 2 described above, and the weight of the upper body 31 is substantially supported by the gantry 3.
In the present embodiment, there is no intermediate member 33, and the lower portion of the upper body 31 is directly mounted on the bottom body portion 30.

In the test room 60 of the present embodiment, the receiving plate 61 is integrally attached to the pillar of the gantry 3.
In the test room 60 of the present embodiment, an upper body raising means such as a jack 62 is installed on the receiving plate 61 of the gantry 3, and the pedestal 3 is lifted by the jack 62 to raise the upper body 31 and the bottom body portion 30. The upper body 31 is separated to form a gap 50 between them. Since the bottom body portion 30 can be pulled out and the bottom portion 21 can be replaced, the repair work is easy.

In the embodiment described above, a gantry 3 as a load supporting member is provided on the outside of the test chambers 2 and 60, and the weight of the upper body 31 is supported by the gantry 3, but the upper part is as shown in the test chamber 65 shown in FIG. The body 31 may be provided with an independent leg portion (load support member) 63, and the upper body 31 may be self-supporting by the leg portion 63.
In the present embodiment, the leg portion 63 is not in contact with the bottom body portion 30, and the load of the upper body portion 31 is not applied to the bottom body portion 30.
Therefore, even if the intermediate member 33 is removed, the upper body 31 is in a state of floating in the air. Since the bottom body portion 30 can be pulled out and the bottom portion 21 can be replaced, the repair work is easy.

Further, the building may be used as a load supporting member, and the upper body 31 may be hung from a beam or the like of the building, or a part of the upper body 31 may be supported by a pillar or the like of the building.

In the test room 60 shown in FIG. 6, the upper body 31 is lifted by the jack 62, but the upper body 31 may be lifted by an overhead crane (upper body raising means) or the like.
Further, only the upper body 31 may be lifted by an overhead crane or the like without going through the gantry 3.

In the above-described embodiment, a block-shaped heat insulating material is used as the intermediate member 33, but a plate is stretched inside and outside the gap 50 between the lower portion of the upper body 31 and the bottom body portion 30 to close the gap 50. A heat insulating material such as glass wool may be packed inside. Further, the gap 50 may be filled with the foamed resin liquid, and the foamed resin liquid may be foamed and cured in the gap 50.

If the intermediate member 33 has rigidity, it is not necessary to always suspend the upper body 31 from the gantry 3 or the like, and the branch wire member 46 may be removed depending on the situation. Further, when repairing the bottom portion 21, a branch wire member 46 may be attached.
The same applies to the test chamber 60 shown in FIG. 6, and if the upper body 31 has rigidity, it is not necessary to always suspend the upper body 31 from the gantry 3 or the like.

In the above-described embodiment, the upper body 31 is suspended by a steel round bar, but the member for suspending the upper body 31 is not limited to the round bar, and is not limited to the round bar, but is a screw material, an L-shaped steel, or a channel steel. It may be a steel material such as. Further, these may be suspended by a member combined with a truss structure or a rigid frame structure.
The steel round bar is a member that maintains a linear shape, but instead of the round bar, the upper body 31 may be suspended by a wire that does not maintain a certain shape, such as a wire, sling, or rope.
Further, the method of supporting the upper body 31 is not limited to the suspended structure, and may be a structure in which the side surface of the upper body 31 is held by a cantilever that horizontally projects from the gantry 3.

In the above-described embodiment, the intermediate member 33 is removed or the upper body 31 is lifted to form a gap 50 between the bottom body portion 30 and the upper body 31. According to this method, not only the bottom body portion 30 can be easily pulled out, but also a new bottom body portion 30 can be easily inserted under the upper body portion 31.
However, in the present invention, it is not essential to form a gap 50 between the bottom body portion 30 and the upper body portion 31. For example, most of the weight of the upper body 31 is supported by other members, but the bottom body portion 30 and the upper body 31 may be substantially in contact with each other.
As a construction procedure, the bottom body 30 is taken out by breaking a part of the bottom body 30 or knocking it out from the side surface.
In many cases, the bottom body portion 30 is taken out while rubbing against the upper body portion 31.
After the bottom body portion 30 is taken out, the upper body portion 31 is in a state of floating in the air.

In the above description of the embodiment, even if the upper body 31 is floated in the air by removing the intermediate member 33 or the like, the upper body 31 does not lose its shape and maintains its original shape.
As described above, it is ideal that the upper body 31 does not lose its shape even if the upper body 31 is floated in the air, but in reality, it may be distorted or bent depending on its own weight.
In addition, some of the heat insulating panels 10, 11 and 12 may fall off.
However, even if the upper body 31 is floated in the air, for example, one side surface portion 23, 25, 26 may fall, the top surface portion 20 and the side surface portions 23, 25, 26 may be separated, or the heat insulating panels 10, 11 may be separated. , 12 does not collapse such that most of them fall off, and the shape of the upper body 31 is generally maintained.
That is, even if the upper body 31 is floated in the air, the shape of the upper body 31 remains the prototype that can be said to be a half-box shape, and the upper body 31 and the bottom body 30 are moved up and down while maintaining the shape of the upper body 31. It is separable.
And although some repair work may be required, the test chamber 2 can be completed by joining with the bottom body portion 30.
