壁構造Wall structure

　本開示は、壁構造に関する。 This disclosure relates to the wall structure.

　特許文献１には、断熱性が補強されたコンテナハウスが記載されている。このコンテナハウスの壁構造は、側壁部と、側壁部から離れて位置する断熱パネルと、断熱パネルの側壁部とは反対側の面に貼り付けられた仕上げパネルと、を備える。 Patent Document 1 describes a container house with reinforced heat insulation. The wall structure of this container house includes a side wall portion, a heat insulating panel located away from the side wall portion, and a finishing panel attached to a surface of the heat insulating panel opposite to the side wall portion.

　断熱パネルは、発泡スチレンなどの断熱材の両面に、鉄板を貼り付けたサンドイッチパネルである。 The heat insulating panel is a sandwich panel in which iron plates are attached to both sides of a heat insulating material such as expanded styrene.

　ところで、特許文献１に記載のコンテナハウスの壁構造では、断熱パネルとして、真空断熱材を含んだ断熱パネルを採用した場合、仕上げパネルにビス等の固定具を打ち付けると、真空断熱材が破損して減圧状態が解除され、断熱性が低下するおそれがある。 By the way, in the wall structure of the container house described in Patent Document 1, when a heat insulating panel containing a vacuum heat insulating material is adopted as the heat insulating panel, the vacuum heat insulating material is damaged when a fixture such as a screw is struck on the finishing panel. The depressurized state is released, and the heat insulating property may decrease.

　また、何らかの原因で真空断熱材が破損して減圧状態が解除されると、真空断熱材が変形して、断熱パネルの外観へ影響を及ぼすおそれがある。 Also, if the vacuum heat insulating material is damaged for some reason and the decompression state is released, the vacuum heat insulating material may be deformed and affect the appearance of the heat insulating panel.

　（実施形態１）
　１．概要
　図１に示す実施形態１の壁構造１は、板材２と、板材２の厚み方向の片側に配置され、真空断熱材３を含んだ断熱板４と、断熱板４の板材２とは反対側に配置される下地材５と、下地材５を断熱板４から離れた位置に支持する支持部材６と、を備える。 (Embodiment 1)
1. 1. Outline The wall structure 1 of the first embodiment shown in FIG. 1 is arranged on one side of the plate material 2 and the plate material 2 in the thickness direction, and is opposite to the heat insulating plate 4 including the vacuum heat insulating material 3 and the plate material 2 of the heat insulating plate 4. A base material 5 arranged on the side and a support member 6 for supporting the base material 5 at a position away from the heat insulating plate 4 are provided.

　上記構成を備えることで、一実施形態の壁構造１では、支持部材６によって下地材５を、真空断熱材３を含んだ断熱板４から離れた位置に支持することができる。そのため、一実施形態の壁構造１では、下地材５にビス等の固定具を打ち込んだ際に、この固定具が真空断熱材３に刺さって真空断熱材３の減圧状態が解除されて断熱性が低下することを防ぐことができ、壁構造１の断熱性の低下を抑制することができる。 By providing the above configuration, in the wall structure 1 of one embodiment, the base material 5 can be supported by the support member 6 at a position away from the heat insulating plate 4 including the vacuum heat insulating material 3. Therefore, in the wall structure 1 of one embodiment, when a fixing tool such as a screw is driven into the base material 5, the fixing tool is stuck in the vacuum heat insulating material 3 to release the decompression state of the vacuum heat insulating material 3 and have heat insulating properties. Can be prevented from being lowered, and the deterioration of the heat insulating property of the wall structure 1 can be suppressed.

　２．詳細
　続いて、実施形態１の壁構造１について更に詳しく説明する。図２には、本実施形態の壁構造１を備えるコンテナ１００を示す一部破断した斜視図が示されている。図２は、図４に示すコンテナ１００を長手方向と平行な断面で切断した図である。以下では、図２及び図４に示す前後、上下及び左右方向を用いて、各構成について説明する。断熱板４に対して板材２が位置する方向を前方と規定し、その反対方向を後方と規定し、波形の板材２の波の山部と谷部とが並ぶ方向を左右方向と規定し、前後方向及び左右方向に直交する方向を上下方向と規定している。 2. 2. Details Subsequently, the wall structure 1 of the first embodiment will be described in more detail. FIG. 2 shows a partially broken perspective view of the container 100 having the wall structure 1 of the present embodiment. FIG. 2 is a view of the container 100 shown in FIG. 4 cut in a cross section parallel to the longitudinal direction. In the following, each configuration will be described using the front-back, up-down, and left-right directions shown in FIGS. 2 and 4. The direction in which the plate material 2 is located with respect to the heat insulating plate 4 is defined as the front, the opposite direction is defined as the rear, and the direction in which the wave peaks and valleys of the corrugated plate 2 are lined up is defined as the left-right direction. The direction orthogonal to the front-back direction and the left-right direction is defined as the vertical direction.

　図１及び図２に示すように、壁構造１は、板材２と、真空断熱材３を含んだ断熱板４と、下地材５と、支持部材６とを備える。 As shown in FIGS. 1 and 2, the wall structure 1 includes a plate material 2, a heat insulating plate 4 including the vacuum heat insulating material 3, a base material 5, and a support member 6.

　図４に示す壁構造１を備えるコンテナ１００は、内部に収納空間を有する、一方向（詳しくは左右方向）に長尺な直方体状の箱体である。コンテナ１００は、例えば、船舶や貨物列車などを用いて貨物を輸送する際に用いられる保冷コンテナである。保冷コンテナには、内部空間の温度を低温に保つために、冷凍機等の空調装置が設けられる。 The container 100 having the wall structure 1 shown in FIG. 4 is a rectangular parallelepiped box body having a storage space inside and being long in one direction (specifically, the left-right direction). The container 100 is a cold storage container used when transporting freight using, for example, a ship or a freight train. The cold storage container is provided with an air conditioner such as a refrigerator in order to keep the temperature of the internal space low.

　コンテナ１００は、底壁１０１と、天井壁１０２と、底壁１０１と天井壁１０２の間の空間を囲む四つの側壁１０３とを備える。本実施形態では、前後二つの側壁１０３のそれぞれが、図１に示す壁構造１を備える。以下では、前側の側壁１０３が備える壁構造１について説明する。後側の側壁１０３が備える壁構造１は、前側の側壁１０３が備える壁構造１と前後逆の構造である。 The container 100 includes a bottom wall 101, a ceiling wall 102, and four side walls 103 that surround the space between the bottom wall 101 and the ceiling wall 102. In the present embodiment, each of the two front and rear side walls 103 includes the wall structure 1 shown in FIG. Hereinafter, the wall structure 1 provided in the front side wall 103 will be described. The wall structure 1 provided on the rear side wall 103 is a structure opposite to that of the wall structure 1 provided on the front side wall 103.

　図１及び図２に示すように、支持部材６は、断熱板４と下地材５の間に位置する柱７（詳しくは複数の柱７）である。柱７は、金属製であり、例えば、断面Ｕ字状の溝形鋼である。柱７は、図３Ａ及び図３Ｂに示すように、コンテナ１００の天井（詳しくは天井壁１０２）と床（詳しくは底壁１０１）のそれぞれに取り付けられた柱受け７０に支持されている。 As shown in FIGS. 1 and 2, the support member 6 is a pillar 7 (specifically, a plurality of pillars 7) located between the heat insulating plate 4 and the base material 5. The pillar 7 is made of metal, for example, a channel steel having a U-shaped cross section. As shown in FIGS. 3A and 3B, the pillar 7 is supported by a pillar holder 70 attached to each of the ceiling (specifically, the ceiling wall 102) and the floor (specifically, the bottom wall 101) of the container 100.
