Summary of the Invention

Problems to be Solved by the Invention

[0005] In a building provided with a heat insulation material or a moisture prevention material between divided bodies, it is assumed that the gap between the divided bodies will widen due to earthquakes, temperature differences, etc.

[0006] When the gap between the bodies widens, accordingly, the heat insulation material and the moisture prevention material provided between the bodies may be damaged or displaced, allowing air (hot air, cold air, and moisture) to enter and exit, which may hinder heat insulation and moisture prevention inside the bodies.

Means for Solving the Problems

[0007] Therefore, in the present invention according to claim 1, in an inter-structure insulation and moisture-proofing structure that provides insulation and moisture-proofing to the inside of a structure by providing insulation and moisture-proofing materials between divided structural bodies, a pair of insulation bodies closely placed between divided structural bodies are provided detachably, and a flexible moisture-proofing material is provided to cover the outside of the detachable portion of the pair of insulation bodies in a flexed state.

[0008] Furthermore, in the present invention according to claim 2, the moisture-proof body is provided in a double layer on the outside of the separable portion of the pair of heat-insulating bodies, as in the present invention according to claim 1.

[0009] Furthermore, in the present invention according to claim 3, the end of the moisture-proof body is sandwiched between the building structure and the heat-insulating body, as in the present invention according to claim 1 or claim 2. [Effects of the Invention]

[0010] Furthermore, the present invention provides the following effects.

[0011] In other words, in the present invention, in an inter-structure insulation and moisture-proofing structure that provides insulation and moisture protection inside the structure by providing insulation and moisture-proofing materials between divided structural bodies, a pair of insulation bodies are provided in close contact between the divided structural bodies in a separable manner, and a flexible moisture-proofing material is provided in a flexed state to cover the outside of the separable portion of the pair of insulation bodies. Therefore, even if the gap between the divided structural bodies widens due to vibrations such as earthquakes or contraction due to temperature differences, the pair of insulation bodies will separate, and the separated portion of the insulation bodies will be covered with the moisture-proofing material, thereby preventing the entry and exit of hot or cold air or air accompanied by moisture, and maintaining insulation and moisture protection inside the structure.

[0012] In particular, if the moisture barrier is provided in a double layer on the outside of the separable portion of the pair of insulating bodies, the double layer of moisture barriers can more effectively prevent the entry and exit of hot or cold air or humid air, thereby maintaining insulation and moisture protection inside the structure.

[0013] Furthermore, if the end of the moisture-proofing body is sandwiched between the building structure and the insulating body, the moisture-proofing body can be held between the building structure and its peeling can be prevented. [Brief explanation of the drawing]

[Figure 4] A cross-sectional diagram illustrating the function of the inter-structure insulation and moisture-proofing structure according to the second embodiment. [Modes for carrying out the invention]

[0015] The specific configuration of the inter-structure insulation and moisture-proofing structure according to the present invention will be described below with reference to the drawings.

[0016] [Example 1] As shown in Figure 1, the inter-structure insulation and moisture-proof structure 1 is formed by arranging concrete structures 2 and 3 side by side in a cold storage warehouse, with a concrete structure 2 forming the cold storage warehouse and another concrete structure 3 forming the cold storage warehouse. A certain gap is formed between the left and right structures 2 and 3 (between the ceilings in Figure 1), and insulation and moisture-proof materials are provided in this gap and on the inside of structures 2 and 3, thereby providing insulation and moisture protection inside structures 2 and 3.

[0017] Structures 2 and 3 have concave steps 4 and 5 formed on the outer (upper) sides of the sides facing the gap, and moisture barriers 6 are housed along the gap in both steps 4 and 5, with the moisture barriers 6 bent outward in a convex shape.

[0018] This moisture-proof body 6 only needs to have moisture-proof property and is formed of a material of closed-cell nitrile synthetic rubber system. In addition, the moisture-proof body 6 may also have heat insulation property in addition to moisture-proof property, and may also have flexibility and elasticity. Both ends of the outer peripheral surface of the moisture-proof body 6 are in close contact with the steps 4 and 5 of the bodies 2 and 3.

[0019] In addition, the bodies 2 and 3 accommodate a pair of rectangular plate-shaped heat insulation bodies 7 and 8 that can be separated left and right in a state of being in close contact with each other along the gap, and accommodate a sheet-shaped moisture-proof body 9 along the gap in a state of being bent directly above the separable portions of the pair of heat insulation bodies 7 and 8, and sandwich both left and right ends of the moisture-proof body 9 with the bodies 2 and 3 and the heat insulation bodies 7 and 8. In addition, both left and right ends of the previous moisture-proof body 6 are also sandwiched by the heat insulation bodies 7 and 8 via the moisture-proof body 9 and the bodies 2 and 3. Thereby, regardless of the expansion and contraction of the gap between the bodies 2 and 3, the moisture-proof bodies 6 and 9 are held between the bodies 2 and 3 to prevent the moisture-proof bodies 6 and 9 from peeling off.

[0020] These heat insulation bodies 7 and 8 only need to have heat insulation property and are formed of extruded polystyrene foam molding plates. In addition, the heat insulation bodies 7 and 8 may also have moisture-proof property in addition to heat insulation property, and may also have elasticity. The heat insulation bodies 7 and 8 are accommodated in the gap in a state of being in close contact with each other, and press and sandwich the moisture-proof bodies 6 and 9 with the bodies 2 and 3.

[0021] In addition, the moisture-proof body 9 only needs to have moisture-proof property and is formed of rubber, asphalt, or the like. In addition, the moisture-proof body 9 may also have heat insulation property and waterproof property in addition to moisture-proof property, and may also have flexibility. The moisture-proof body 9 is accommodated along the gap in a state of being bent directly above the separable portions of the pair of heat insulation bodies 7 and 8.

[0022] In addition, in the above-described body intermittent heat insulation and moisture-proof structure 1, a sheet-shaped moisture-proof body 15 similar to the moisture-proof body 9 is also provided between the steps 4 and 5 of the bodies 2 and 3 and the ends of the moisture-proof body 6.

[0023] As described above, in the inter-structure insulation and moisture-proof structure 1, a pair of insulating bodies 7 and 8 are provided detachably between the structural bodies 2 and 3, and flexible moisture-proof bodies 6 and 9 are provided in a flexible state to cover the outside of the detachable portion of the pair of insulating bodies 7 and 8. As a result, the gap formed between the separated structural bodies 2 and 3 is closed by the moisture-proof bodies 6 and 9 and the insulating bodies 7 and 8 under normal conditions (when not affected by earthquakes, temperature differences, etc.). Note that the moisture-proof bodies 6 and 9 and the insulating bodies 7 and 8 may be provided as a single piece extending along the gap between the structural bodies 2 and 3, or multiple pieces may be provided with their ends overlapping in a layered manner.

[0024] The above-mentioned structural bodies 2 and 3 have a moisture-proof layer 10 formed by spraying a moisture-proof material onto their inner surfaces, an insulating layer 11 formed by spraying an insulating material such as urethane, a fire-resistant layer 12 formed by coating the upper surface thereof with a fire-resistant material, and a finishing material 14 attached via a support material 13.

[0025] In this manner, the inter-structure insulation and moisture-proof structure 1 provides insulation and moisture protection inside the structures 2 and 3 by layering multiple insulation and moisture-proof materials. In particular, a pair of insulation bodies 7 and 8 are detachably installed in the gap between structures 2 and 3, and flexible moisture-proof bodies 6 and 9 are used to cover the outside of the detachable portions of the pair of insulation bodies 7 and 8 in a flexed state.

[0026] Therefore, under normal conditions (when not affected by earthquakes, temperature differences, etc.), the gaps formed between the separated structural bodies 2 and 3 are sealed by the moisture barriers 6 and 9 and the insulation bodies 7 and 8, allowing for good insulation and moisture protection inside the structural bodies 2 and 3.

[0027] Furthermore, in abnormal situations (when the gap between the separated structural bodies 2 and 3 widens due to vibrations such as earthquakes or contraction due to temperature differences, etc.), a pair of separable insulation bodies 7 and 8 have arbitrarily formed weak (easily separable) parts. As shown in Figure 2, even if the structural bodies 2 and 3 are displaced from side to side, widening the gap and causing cracks in the insulation layer 11 and fireproof layer 12, the pair of separable insulation bodies 7 and 8 actively and selectively separate in accordance with the displacement of the structural bodies 2 and 3. Consequently, the deflection of the moisture barriers 6 and 9, which are sandwiched at both ends by the insulation bodies 7 and 8 and the structural bodies 2 and 3, decreases, while the moisture barriers 6 and 9 remain stretched outside the separated parts of the insulation bodies 7 and 8, thus covering the widened gap between the structural bodies 2 and 3.

[0028] As a result, the inter-structure insulation and moisture-proofing structure 1 can prevent the entry and exit of air (hot air, cold air, and moisture) not only under normal conditions (when unaffected by earthquakes, temperature differences, etc.) but also under abnormal conditions (when the gap between the separated structures 2 and 3 widens due to vibrations such as earthquakes or contraction due to temperature differences, etc.), thereby ensuring good insulation and moisture-proofing inside the structures 2 and 3.

[0029] [Example 2] In the inter-structure insulation and moisture-proof structure 1 of Example 1 described above, the outside of a pair of separable insulation bodies 7 and 8 is covered with a sheet-like moisture-proof material 9, and the outside of the insulation bodies 7 and 8 and the moisture-proof material 9 is covered with a moisture-proof material 6 that has different properties (thickness, etc.) from the moisture-proof material 9. However, the structure is not limited to this, and as shown in Figure 3, in the inter-structure insulation and moisture-proof structure 1' of Example 2, the outside of a pair of separable insulation bodies 7 and 8 is covered with a moisture-proof material 6, and the outside of the insulation bodies 7 and 8 and the moisture-proof material 6 may be covered with a moisture-proof material 9 (9a, 9b) that has different properties (thickness, etc.) from the moisture-proof material 6. In Example 2, members with similar structures are given the same reference numerals as in Example 1 to omit redundant explanations.

[0030] In this second embodiment of the inter-structure insulation and moisture-proof structure 1', the moisture-proof body 9 is composed of a sheet-like moisture-proof body 9a provided between the concave steps 4, 5 formed on the outer side (upper side) of the side facing the gap between the structures 2, 3 and the end of the moisture-proof body 6, and between the inner side (lower side) of the side facing the gap between the structures 2, 3 and the insulation bodies 7, 8, and a sheet-like moisture-proof body 9b straddling the outer side (upper side) of the structures 2, 3. The ends of the moisture-proof body 9a and the moisture-proof body 9b are held together by a plate material 16 and fastened to the structures 2, 3 with fasteners 17.

[0031] In this structural insulation and moisture-proof structure 1' of Example 2, as shown in Figure 3, under normal conditions (when not affected by earthquakes or temperature differences), the gap formed between the separated structural bodies 2 and 3 is closed by the moisture-proof elements 6 and 9 and the insulation elements 7 and 8, allowing for good insulation and moisture protection inside the structural bodies 2 and 3. Moreover, as shown in Figure 4, under abnormal conditions (when the gap between the separated structural bodies 2 and 3 widens due to vibrations such as earthquakes or contraction due to temperature differences), a weak (easily separable) portion is arbitrarily formed in the pair of separable insulation elements 7 and 8, causing the structural bodies 2 and 3 to displace from side to side, widening the gap and causing cracks in the insulation layer 11 and the fire-resistant layer 12. Furthermore, the separable pair of insulated bodies 7 and 8 actively and selectively separate in accordance with the displacement of the structural bodies 2 and 3. Consequently, the deflection of the moisture barriers 6 and 9, which are sandwiched at both ends by the insulated bodies 7 and 8 and the structural bodies 2 and 3, decreases, while the moisture barriers 6 and 9 remain stretched outside the separated portion of the insulated bodies 7 and 8, thereby covering the widened gap between the structural bodies 2 and 3. This prevents the entry and exit of air (hot air, cold air, and moisture) and ensures good insulation and moisture protection inside the structural bodies 2 and 3, not only under normal conditions (when unaffected by earthquakes or temperature differences) but also under abnormal conditions (when the gap between the separated structural bodies 2 and 3 widens due to vibrations such as earthquakes or contraction due to temperature differences).

[0032] As described above, the above-mentioned inter-structure insulation and moisture-proof structure 1,1' is configured such that a pair of insulation bodies 7,8 are detachably provided in close contact between the separated structures 2,3, and a flexible moisture-proof body 6,9 is used to cover the outside of the detachable portions of the pair of insulation bodies 7,8 in a flexed state.

[0033] Therefore, in the above-described inter-structure insulation and moisture-proof structure 1,1', even if the gap between the separated structures 2,3 widens due to vibrations such as earthquakes or contraction due to temperature differences, the pair of insulation bodies 7,8 will separate, and the separated parts of the insulation bodies 7,8 will be covered with moisture-proof bodies 6,9, thereby preventing the entry and exit of hot or cold air or air accompanied by moisture, and maintaining insulation and moisture protection inside the structures 2,3.

[0034] Furthermore, the above-mentioned inter-structure insulation and moisture-proof structure 1,1' has a configuration in which moisture-proof elements 6,9 are provided in a double layer on the outside of the separable portions of the pair of insulation elements 7,8.

[0035] Therefore, in the above-described inter-structure insulation and moisture-proof structure 1,1', the double-layered moisture barriers 6,9 can further prevent the entry and exit of hot or cold air or humid air, thereby maintaining insulation and moisture protection inside the structures 2,3.

[0036] Furthermore, the above-mentioned inter-structure insulation and moisture-proof structure 1,1' has a configuration in which the ends of the moisture-proof elements 6,9 are sandwiched between the structure 2,3 and the insulation elements 7,8.

[0037] Therefore, in the above-described inter-structure insulation and moisture-proof structure 1,1', the moisture-proof elements 6,9 can be held between the structures 2,3, preventing the moisture-proof elements 6,9 from peeling off. [Explanation of Symbols]
