Description

[Technical Field]

[0001] This specification discloses a technique relating to an external thermal insulation structure for a storage facility. [Background technology]

[0002] In recent years, there has been a trend to renovate old houses to suit modern lifestyles while preserving the traditional architectural merits of the houses. Patent Document 1 describes a technique for renovating the halls of old houses into accommodation facilities in the form of a capsule hotel. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-1488 Summary of the Invention [Problem to be solved by the invention]

[0004] The technology of Patent Document 1 has the problem that it does not consider specific techniques for renovating storehouses such as earthen storehouses and stone storehouses. [Means for solving the problem]

[0005] One embodiment disclosed herein is an external insulation structure for a storehouse. This external insulation structure for a storehouse includes a foundation structure installed on the ground outside the storehouse's existing foundation, a heat-shielding sheet attached to the exterior of the storehouse's existing outer wall, a plurality of pillars installed vertically on the foundation structure along the existing outer wall, a connecting structure connecting the pillars to the existing outer wall, exterior wall material covering the exterior of the plurality of pillars, insulation material installed between the plurality of pillars adjacent to the heat-shielding sheet, and a ventilation layer installed between the plurality of pillars and the insulation material and the exterior wall material. This external insulation structure for a storehouse has a relatively high thermal capacity compared to a typical house, and by externally insulating the existing outer wall, heat generated inside the storehouse can be radiated to the interior, thereby achieving energy savings. This is particularly useful when using thermal energy-consuming equipment such as a rock bath, sauna, or cooling room inside the storehouse. [Brief explanation of the drawings]

[0006] [Figure 1] This is a cross-sectional view showing the structure of the storehouse. [Figure 2] This is a cross-sectional view showing the structure of the storehouse. DETAILED DESCRIPTION OF THE INVENTION

[0007] Fig. 1 is a cross-sectional view showing the structure of storehouse 800. Fig. 2 is a cross-sectional view showing the structure of storehouse 800. The cross-sectional view of Fig. 1 shows the structure of a part of storehouse 800 cut along the vertical direction. The cross-sectional view of Fig. 2 shows the structure of a part of storehouse 800 cut along the horizontal direction.

[0008] Storehouse 800 is a building that has been renovated from an existing stone storehouse. Storehouse 800 may also be a building that has been renovated from an existing earthen storehouse. The interior of storehouse 800 has been renovated into a bedrock bath facility. The interior of storehouse 800 may also be renovated into other facilities that use thermal energy, such as a sauna and a cooling room. Storehouse 800 comprises an existing foundation 810, an existing outer peripheral wall 820, a floor structure 850, and an external insulation structure for storehouse 100.

[0009] The existing foundation 810 of the storehouse 800 is a foundation structure that was installed before the construction of the external thermal insulation structure for a storehouse 100. The existing foundation 810 is buried below the ground level GL. The existing foundation 810 supports the existing outer peripheral wall 820.

[0010] The existing outer perimeter wall 820 of the storehouse 800 is an outer perimeter wall structure that was installed before the construction of the external thermal insulation structure for a storehouse 100. The existing outer perimeter wall 820 is installed on an existing foundation 810. The existing outer perimeter wall 820 has a structure in which multiple tuff blocks are stacked.

[0011] The floor structure 850 of the storehouse 800 is a floor structure that has been renovated as a bedrock bath facility. The floor structure 850 is a structure in which anti-termite treated insulation material, a heat shield sheet, a heater panel, and a finishing material are installed in this order on top of leveled concrete.

[0012] The external thermal insulation structure 100 for a storehouse 800 is a structure constructed from the lower end to the upper end of an existing outer peripheral wall 820. The external thermal insulation structure 100 for a storehouse comprises a foundation structure 110, a base material 120, a heat shield sheet 130, a plurality of pillar materials 140, a plurality of cross members 145, a thermal insulation material 150, a ventilation layer 160, and an exterior wall material 170.

[0013] The foundation structure 110 of the storehouse 800 is a structure provided on the ground GL outside the existing foundation 810 of the storehouse 800. The foundation structure 110 is a reinforced concrete foundation.

[0014] The base material 120 of the storehouse 800 is a piece of wood placed on the foundation structure 110. The base material 120 supports a number of pillar materials 140.

[0015] The heat shield sheet 130 of the storehouse 800 is a sheet attached to the outside of the existing outer peripheral wall 820 of the storehouse 800. The heat shield sheet 130 is attached to the surface of the existing outer peripheral wall 820 with double-sided tape.

[0016] The pillars 140 of the storehouse 800 are pieces of wood installed vertically on the foundation structure 110 along the existing peripheral wall 820. The pillars 140 are connected to the existing peripheral wall 820 by connecting structures 142. The connecting structures 142 are structures in which metal fittings are inserted into holes drilled in the pillars 140 and the existing peripheral wall 820, and the gaps are filled with adhesive. The gaps created between the pillars 140 and the heat shield sheet 130 are filled with a filler such as urethane foam.

[0017] The horizontal member 145 of the storehouse 800 is a piece of wood attached between two pillars 140. The multiple horizontal members 145, together with the multiple pillars 140, form a lattice structure. The horizontal member 145 holds the heat insulating material 150 so that it is pressed against the heat shield sheet 130. By holding the heat insulating material 150 on the heat shield sheet 130 side, the horizontal member 145 forms an air-permeable layer 160 between the heat insulating material 150 and the exterior wall material 170.

[0018] The heat insulating material 150 of the storehouse 800 is a building material laid adjacent to the heat shield sheet 130 between a plurality of pillars 140. The heat insulating material 150 is a termite-proof treated heat insulating material.

[0019] The ventilation layer 160 of the storehouse 800 is a gap provided between the insulating material 150 and the exterior wall material 170 between the multiple pillars 140. The ventilation layer 160 allows air to flow from the lower end to the upper end of the external thermal insulation structure for a storehouse 100.

[0020] The exterior wall material 170 of the storehouse 800 is a building material that covers the outside of the multiple pillar materials 140. The exterior wall material 170 can be made of various siding materials, ALC concrete, etc.

[0021] According to the external insulation structure 100 for a storehouse described above, by externally insulating the existing outer wall 820 of the storehouse 800, which has a relatively high heat capacity compared to a typical house, the heat generated inside the storehouse 800 can be radiated to the inside, thereby achieving energy savings.

[0022] The technology disclosed in this specification is not limited to the above-described embodiments, examples, and modifications, and can be realized in various configurations without departing from the spirit thereof. For example, among the technical features of the above-described embodiments, examples, and modifications, those corresponding to the technical features of each form described in the Summary of the Invention section can be appropriately replaced and combined to solve some or all of the above-described problems or achieve some or all of the above-described effects. Furthermore, technical features not described as essential in this specification can be appropriately deleted. [Explanation of symbols]
