Description

  In the present invention, an upper chamber and a lower chamber having a difference in room temperature are provided adjacent to each other in the vertical direction, and a lower support member disposed in the lower chamber is provided with a shaft from an upper column disposed in the upper chamber. The present invention relates to a heat insulating structure of a building configured to support force.

As such a building, for example, there is a building for a refrigerated warehouse in which the upper part is a refrigerated freezer compartment and the lower part is a normal office room, and in that case, the problem is the condensation in the lower office room Occurrence. Condensation on the ceiling and walls in the office can be prevented to some extent by laying or burying insulation, but for example, slabs and beams placed in the lower office If it is configured to support the axial force from the upper column placed in the refrigerated freezer compartment, the slab or beam of the office room inevitably becomes a heat bridge from the upper column of the refrigerated refrigerator chamber, and condensation occurs on the slab or beam. Will do.
In order to prevent the occurrence of such condensation, a method of covering the beam with a heat insulating material is usually adopted, but it requires a very complicated heat insulating work, resulting in an increase in cost, and it is necessary to cover with a heat insulating material. The larger the area, the more prominent it will be and the construction period will be prolonged.

Therefore, conventionally, a heater for heating is embedded in the vicinity of the joint between the upper column and the slab, and a temperature sensor and a humidity sensor are installed at necessary locations, and the heater is based on the detection result of the temperature sensor and the humidity sensor. A configuration has been proposed in which the operation is controlled manually or automatically (see, for example, Patent Document 1).
In addition, hard wood with relatively low thermal conductivity and strength is interposed between the upper column and the lower footing, or heat bridge is used to prevent heat bridge Are also known (see, for example, Patent Documents 2 and 3).

Japanese Patent Application Laid-Open No. 11-294942 JP 2002-188237 A Japanese Patent Laid-Open No. 10-82145

However, in the prior art described in Patent Document 1, not only maintenance of the heater embedded in the vicinity of the joint between the upper column and the slab is required, but also the operation of the heater needs to be controlled, so the running cost is high. Moreover, there is a possibility of failure.
Moreover, in the prior art described in Patent Documents 2 and 3, since the axial force from above is transmitted downward through hard wood or heat insulating resin, although it is relatively strong, hard wood or heat insulating resin. It is unsuitable for transmitting a large axial force downward through the, and this has a problem.

  The present invention pays attention to such a conventional problem, and the purpose thereof is not particularly required for maintenance work, and can be reliably transmitted even with a large axial force. An object of the present invention is to provide a heat insulating structure for a building that can surely prevent the above.

  In the first characteristic configuration of the present invention, an upper chamber and a lower chamber having a difference in room temperature are provided adjacent to each other in the vertical direction, and a lower support member disposed in the lower chamber is disposed in the upper chamber. A heat insulating structure for a building configured to support the axial force from the upper column, and the support body for transmitting the axial force from the upper column to the lower support member is a plate-like high hardness rubber. In the state where the laminated rubber support is located inside the outline of the upper column and the lower support member in a plan view, and a heat insulating material is arranged around the laminated rubber support. Located between the upper column and the lower support member.

  According to the first characteristic configuration of the present invention, the support body for transmitting the axial force from the upper column arranged in the upper chamber to the lower support member arranged in the lower chamber is formed by using a plate-like high hardness rubber and a steel plate. Since it is constituted by laminated rubber bearings that are alternately laminated, the axial force from the upper column can be transmitted to the lower support member as desired, and a heat bridge between the upper column and the lower support member can be generated. Can be prevented.

That is, considering only the heat bridge, it is possible to use a block-like high-hardness rubber as a support body, but in that case, deformation of the block-like high-hardness rubber due to an axial force from above becomes a problem. . On the other hand, if only the transmission of axial force is considered, block-shaped steel can be used, but naturally a heat bridge becomes a problem.
On the other hand, by using a laminated rubber bearing body in which plate-like high-hardness rubber and steel plates are laminated alternately, the heat insulation and strength of the high-hardness rubber and the strength of the steel plate are effectively used to achieve the desired heat bridge. Not only can the prevention effect be obtained, but even a large axial force can be reliably transmitted to the lower support member.

  Then, the laminated rubber bearing body is positioned between the upper column and the lower support member in a plan view, and is disposed between the upper column and the lower support member in a state where a heat insulating material is arranged around the upper column and the lower support member. So, in other words, the laminated rubber support is kept to the size necessary for axial force transmission, and a heat insulating material is arranged around the laminated rubber support so that the heat bridge between the upper column and the lower support member is prevented. Will also be certain.

  According to a second characteristic configuration of the present invention, a base plate is disposed between the upper column and the laminated rubber support, the heat insulating material is positioned around the laminated rubber support, and the heat insulating material. In a state where a plurality of high-hardness rubber supports are positioned outside, the laminated rubber support, the heat insulating material, and the high-hardness rubber support are arranged between the base plate and the lower support member. By the way.

According to the second characteristic configuration of the present invention, since the base plate is disposed between the upper column and the laminated rubber support, the axial force from the upper column is distributed to the base plate.
Then, in the state where the heat insulating material is located around the laminated rubber bearing body and a plurality of high-hardness rubber supports are located outside the heat insulating material, the laminated rubber bearing body and the heat insulating material. Since the high-hardness rubber support is disposed between the base plate and the lower support member, the axial force distributed on the base plate is mainly supported by the lower support member via the laminated rubber support located at the center thereof. Will be communicated to.
In addition, a plurality of high-hardness rubber supports located outside the heat-insulating material also contribute to the transmission of axial force, so the heat-insulating material located between the high-hardness rubber support and the laminated rubber support Almost no axial force acts, so the heat bridge prevention effect by the heat insulating material is maintained for many years.

  According to a third characteristic configuration of the present invention, a plurality of anchor bolts projecting from the lower support member are extended upward through the heat insulating material and the base plate, and a high-hardness rubber is provided at an extended end portion thereof. A nut is screwed through a washer so that the base plate is fixed to the lower support member.

According to the third characteristic configuration of the present invention, the plurality of anchor bolts protruding from the lower support member are extended upward through the heat insulating material and the base plate, and the nut is screwed into the extended end portion. Since the base plate is fixed to the lower support member, the base plate and the laminated rubber support body and the heat insulating material positioned below the base plate are firmly fixed to the lower support member by the anchor bolt and the nut.
Nevertheless, since the nut is screwed into the anchor bolt via the high hardness rubber washer, the heat bridge caused by the anchor bolt is also reliably suppressed.

  According to a fourth characteristic configuration of the present invention, a sheath tube surrounding a lower end portion of the upper column protrudes upward from the base plate, and a lower end portion of the upper column is located in the sheath tube and is made of high hardness rubber. It is located on the base plate through a sheet.

  According to the fourth characteristic configuration of the present invention, the sheath pipe surrounding the lower end portion of the upper column protrudes upward from the base plate, and the lower end portion of the upper column is located in the sheath tube and the high hardness rubber sheet is disposed. The heat bridge between the upper column and the base plate is suppressed by the high-hardness rubber sheet, and the lower end of the upper column is located in the sheath tube and is mounted on the base plate. Because it is only placed, it can be expected to suppress the earthquake.
