Description

[Technical field]

[0001] The present invention relates to a sandwich panel mask system and a sandwich panel mask construction method that can be used for the roofs and exterior walls of buildings, etc. [Background technology]

[0002] Sandwich panels, which are made by sandwiching insulating material between metal plates and covering them, have various advantages when used as exterior materials for buildings, since they have high insulating and airtight properties and are easy to handle during construction. However, depending on the type of insulating material used in sandwich panels, it may be difficult to clear regulations such as fireproof certification and non-combustible certification, making it difficult to use them as exterior materials for buildings.

[0003] Therefore, a structure has been proposed in which a covering material made of a fire-resistant certified material is installed on the outside of the sandwich panel. For example, Patent Document 1 describes a roof structure in which a roof material is fixed to the outside of a sandwich panel. The roof material is fixed to a support member by penetrating the sandwich panel with a first fastener, or is fixed to the sandwich panel with a second fastener.

[0004] [Patent Document 1] JP 2016-211242 A Summary of the Invention [Problem to be solved by the invention]

[0005] Since the covering material is exposed to the elements, it is necessary to ensure that the mounting strength is sufficient, but the above-mentioned conventional technology has the problem that the mounting strength is insufficient.

[0006] An object of the present invention is to provide a sandwich panel mask system and a sandwich panel mask construction method that can improve the attachment strength of a covering material while ensuring airtightness and thermal insulation. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the present invention provides a mask system for a sandwich panel used as an exterior material for a building, comprising a sandwich panel formed in a panel shape by sandwiching an insulating material between metal plates and having a convex portion at one end and a concave portion at the other end, a support member arranged in a fitting portion where the convex portion of one of the adjacent sandwich panels and the concave portion of the other sandwich panel fit together, and a covering material fixed to the support member and covering the outside of the sandwich panel, wherein the support member has a fixing portion fixed inside the fitting portion, an attachment portion that protrudes outside the fitting portion and to which the covering material is attached, and a clamping portion located between the fixing portion and the attachment portion and supported by being clamped between the end face of the one sandwich panel and the end face of the other sandwich panel at the fitting portion.

[0008] In the sandwich panel mask system of the present invention, a sandwich panel is formed by sandwiching a heat insulating material between metal plates and having a convex portion at one end and a concave portion at the other end, and is used as an exterior material for a building. Adjacent sandwich panels are joined by fitting the convex portion of one sandwich panel with the concave portion of the other sandwich panel at a fitting portion. A covering material that covers the outside of the sandwich panel is fixed to a support member arranged at the fitting portion.

[0009] By using fireproof or non-combustible certified materials as covering materials, it becomes possible to use sandwich panels using insulation materials (e.g. urethane-based insulation materials) that are difficult to clear regulations such as fireproof or non-combustible certification as exterior materials for buildings. This allows the use of light, highly insulating urethane-based insulation materials, improving insulation performance without putting a strain on structural members. It also reduces the use of studs and furring strips as the framework of the building. It also makes it possible to complete installation work using only cranes or aerial work vehicles without constructing scaffolding, improving workability. Furthermore, it contributes to energy conservation by achieving high insulation, while improving the design of the building by using covering materials with rich design.

[0010] In particular, in the sandwich panel mask system of the present invention, adjacent sandwich panels are joined by fitting the recesses and protrusions, so that the airtightness and heat insulation are high, and since the support member is fixed inside the fitting portion, the support member does not penetrate to the inside of the sandwich panel. Therefore, airtightness can be ensured, and the support member can be prevented from becoming a thermal bridge, so that heat insulation can be ensured. Furthermore, since the support member is supported by being sandwiched between the end face of one sandwich panel and the end face of the other sandwich panel at the fitting portion, the support strength of the support member can be improved compared to the case where the support member is fixed to the surface of the sandwich panel, etc. Therefore, the attachment strength of the covering material attached to the support member can be improved while ensuring airtightness and heat insulation.

[0011] In addition, in order to achieve the above-mentioned object, the present invention provides a mask construction method for sandwich panels used as exterior materials for buildings, in which a sandwich panel is formed in a panel shape by sandwiching an insulating material between metal plates and has a convex portion at one end and a concave portion at the other end, and is fixed to the structural member together with a support member by a fastener that penetrates the convex portion and fastens it to the structural member, and the convex portion of one of the adjacent sandwich panels and the concave portion of the other sandwich panel are fitted together so that the support member is supported by being sandwiched between the end face of one of the sandwich panels and the end face of the other sandwich panel at a fitting portion where the convex portion of one of the adjacent sandwich panels and the concave portion of the other sandwich panel are fitted together, and a covering material is attached to the portion of the support member protruding outward from the fitting portion to cover the outside of the sandwich panels. Effect of the Invention

[0012] According to the present invention, the mounting strength of the covering material can be improved while ensuring airtightness and heat insulation. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0015] <Configuration of sandwich panel mask system> The configuration of a sandwich panel mask system according to an embodiment will be described with reference to Figures 1 and 2. Figure 1 is a perspective view showing an example of the configuration of a sandwich panel mask system according to an embodiment, and Figure 2 is a cross-sectional view taken along line II-II of Figure 1 showing an example of the cross-sectional configuration of a sandwich panel.

[0016] The sandwich panel mask system 1 according to the embodiment is used for exterior materials (roofs, exterior walls, etc.) of buildings. As shown in FIG. 1, the sandwich panel mask system 1 includes a sandwich panel 3, a support member 5, and a covering material 7. As shown in FIG. 2, the sandwich panel 3 is configured in a panel shape by sandwiching a heat insulating material 9 between metal plates 11. The metal plates 11 cover the entire surface of the heat insulating material 9, including the outer surface, inner surface, one side and other side surfaces, etc. The heat insulating material is, for example, a urethane-based heat insulating material such as polyurethane (PU) or polyisocyanurate (PIR). Note that heat insulating materials other than urethane materials such as rock wool and glass wool may be used. The metal plate is, for example, an iron plate, an aluminum plate, a stainless steel plate, various steel plates (for example, painted steel plate, galvanized steel plate), etc. Note that the sandwich panel mask system 1 may be used not only for exterior materials of buildings but also for interior materials.

[0017] As shown in Fig. 2, the sandwich panel 3 has a convex portion 13 at one end and a concave portion 15 at the other end. As shown in Fig. 1, adjacent sandwich panels 3, 3 are joined by fitting the convex portion 13 of one sandwich panel 3 and the concave portion 15 of the other sandwich panel 3 at a fitting portion 17.

[0018] The insulating material 9 has a property that its insulating performance decreases when it absorbs moisture, and furthermore, moisture that has penetrated into the insulating material 9 freezes when placed under severe low-temperature conditions, which may cause the destruction of not only the insulating layer but also the wall structure itself. The sandwich panel 3 has a metal plate 11 that functions as a moisture-proof layer on the entire surface of the insulating material 9, which can prevent condensation inside the insulating material 9 and maintain its function as an insulating material for a long period of time. Furthermore, when a urethane-based insulating material with high insulating performance is used as the insulating material 9 of the sandwich panel 3, the metal plate 11 can compensate for the fire resistance, which is a weak point of the urethane-based insulating material.

[0019] The support member 5 is a member for supporting the covering material 7, and is arranged in a fitting portion 17 where the convex portion 13 of one adjacent sandwich panel 3 and the concave portion 15 of the other sandwich panel 3 fit together. The material of the support member 5 is not particularly limited as long as it can ensure strength, and is, for example, made of metal. The support member 5 is fixed to the structural member 19 by fastening together with the convex portion 13 of the sandwich panel 3 inside the fitting portion 17 by a fastener 21 that penetrates the convex portion 13 of the sandwich panel 3 and fastens to the structural member 19. The structural member 19 is a member that constitutes the framework of a building, such as a main pillar, a partition wall, a furring strip, etc. The fastener 21 is, for example, a screw or a bolt. The convex portion 13 of one end of the sandwich panel 3 is fixed to the structural member 19 by the fastener 21, and the concave portion 15 of the other end fits and hooks onto the convex portion 13 of the adjacent sandwich panel 3, so that both ends are fixed to the structural member 19.

[0020] The covering material 7 is fixed to the support member 5 and covers the outside of the sandwich panel 3. In other words, the covering material 7 functions as a masking material that masks the outside of the sandwich panel 3. The covering material 7 may be one sheet or multiple sheets, but if multiple sheets are used, they are joined together without any gaps. The covering material 7 may be, for example, an iron plate, an aluminum plate, a stainless steel plate, or various steel plates (for example, a painted steel plate or a galvanized steel plate), but it is preferable to use a material that has obtained fire protection certification or non-combustibility certification. Figure 1 (also Figures 3 and 4 described later) shows a case where the covering material 7 is, for example, corrugated galvanized iron.

[0021] As shown in FIG. 2, the sandwich panel 3 has a pair of protrusions 13a at both ends in the thickness direction (vertical direction in FIG. 2) of the tip of the protrusion 13, and a pair of depressions 15a at both ends in the thickness direction (vertical direction in FIG. 2) inside the depression 15. When the protrusion 13 of one adjacent sandwich panel 3 and the depression 15 of the other sandwich panel 3 are fitted together, the protrusion 13a of one sandwich panel 3 fits into the depression 15a of the other sandwich panel 3 (see FIG. 4 described later). By fitting the protrusion 13a into the depression 15a, the other end of the sandwich panel 3 is hooked onto the one end of the adjacent sandwich panel 3 and fixed to the structural member 19. In addition, the fitting between the protrusion 13a and the depression 15a can further increase the airtightness of the fitting portion 17. A sealant may be provided between the protrusion 13 and the depression 15.

[0022] In addition, the sandwich panel 3 has a covering portion 23 on the outside of the recess 15 at the end portion on the other side. When the protrusion 13 of one adjacent sandwich panel 3 and the recess 15 of the other sandwich panel 3 are fitted together, the covering portion 23 covers the outside of the protrusion 13 fitted into the recess 15.

[0023] <Configuration of support member> The configuration of the support member 5 will be described with reference to Fig. 3 and Fig. 4. Fig. 3 is a cross-sectional view showing an example of the structure of a fitting portion when adjacent sandwich panels are joined, and Fig. 4 is an enlarged cross-sectional view of the fitting portion of Fig. 3.

[0024] 3 and 4, the support member 5 is a plate-like member bent to conform to the shape of the fitting portion 17, and has a fixed portion 5a, an attachment portion 5b, and a clamping portion 5c. The fixed portion 5a, the attachment portion 5b, and the clamping portion 5c are integrally connected to form the support member 5, which is a single component, but the fixed portion 5a, the attachment portion 5b, and the clamping portion 5c may be made into a plurality of components that are connected to form the support member 5.

[0025] The fixing portion 5a is fixed inside the fitting portion 17, specifically, to the outer surface of the convex portion 13. The fixing portion 5a is bent at a right angle from the inner tip of the clamping portion 5c to one side and extends approximately parallel to the surface of the convex portion 13. The fixing portion 5a is fixed to the structural member 19 by fastening together with the convex portion 13 inside the fitting portion 17 by a fastener 21 that penetrates the convex portion 13 of one sandwich panel 3 and fastens to the structural member 19. A washer 22 is sandwiched between the fixing portion 5a and the head of the fastener 21. The washer 22 is made of, for example, rubber or plastic, and prevents direct contact between the fixing portion 5a and the fastener 21. The fixing portion 5a is covered by the covering portion 23 of the sandwich panel 3 having the other recess 15. A curved portion 5d that is curved outward is formed at the tip of the fixing portion 5a, and the curved portion 5d abuts against the inside of the covering portion 23.

[0026] The mounting portion 5b protrudes outward from the fitting portion 17, and the covering material 7 is attached to it. The mounting portion 5b is bent at a substantially right angle from the outer tip of the clamping portion 5c to the other side and extends substantially parallel to the surface of the sandwich panel 3. A support portion 7a provided on the inside of the covering material 7 is fixed to the mounting portion 5b by a fastener 25. The fastener 25 is, for example, a screw or a bolt.

[0027] The clamping portion 5c is located between the fixed portion 5a and the mounting portion 5b in the support member 5. The clamping portion 5c is supported by being sandwiched between the end face 3a of the sandwich panel 3 having one of the convex portions 13 and the end face 3b of the sandwich panel 3 having the other of the concave portions 15 in the fitting portion 17. The end face 3b is the end face of the tip of the covering portion 23. The end faces 3a and 3b are not limited to flat surfaces, and may be curved or uneven surfaces. The lower portion of the clamping portion 5c is bent following the surface shape of the convex portion 13 of one sandwich panel 3, and is in close contact with the outer surface of the convex portion 13.

[0028] <Sandwich panel masking method> Next, an example of a mask construction method for sandwich panels will be described. First, the first sandwich panel 3 is fixed to the structural member 19 together with the fixed portion 5a of the support member 5 by the fastener 21 that penetrates the protruding portion 13 and fastens to the structural member 19. Next, the recessed portion 15 of the second sandwich panel 3 is fitted to the protruding portion 13 of the first sandwich panel 3 to join the second sandwich panel 3 to the first sandwich panel 3. At this time, the protruding portion 13 of the first sandwich panel 3 and the recessed portion 15 of the second sandwich panel 3 are fitted to each other so that the clamping portion 5c of the support member 5 fixed to the protruding portion 13 of the first sandwich panel 3 is sandwiched and supported between the end face 3a of the first sandwich panel 3 and the end face 3b of the second sandwich panel 3 at the fitting portion 17. The joining of the sandwich panel 3 is repeated in this manner. Thereafter, the covering material 7 is attached by fasteners 25 to the mounting portions 5b of the support members 5 protruding outward from the fitting portions 17 of the joined sandwich panels 3, thereby covering the outside of the sandwich panels 3. In this manner, the mask system 1 for the sandwich panels is constructed.

[0029] <Effects of the embodiment> In the sandwich panel mask system 1 described above, a sandwich panel 3 is configured as a panel by sandwiching a heat insulating material 9 between metal plates 11, and has a convex portion 13 at one end and a concave portion 15 at the other end, and is used as an exterior material for a building. Adjacent sandwich panels 3 are joined by fitting the convex portion 13 of one sandwich panel 3 with the concave portion 15 of the other sandwich panel 3 at a fitting portion 17. A covering material 7 that covers the outside of the sandwich panel 3 is fixed to the support member 5 arranged at the fitting portion 17.

[0030] By using materials that have obtained fireproof certification or non-combustible certification as the covering material 7, it becomes possible to use a sandwich panel 3 using an insulating material (e.g., a urethane-based insulating material) that is difficult to clear regulations such as fireproof certification or non-combustible certification, as an exterior material for a building. This allows the use of a urethane-based insulating material that is light and has high insulating performance, so that the insulating performance can be improved without putting a strain on the structural members 19. In addition, since the sandwich panel 3 has a certain degree of strength, it is possible to reduce the use of studs and furring strips as the framework of the building. In addition, since the sandwich panel 3 is configured in a panel shape and is easy to handle, it is possible to complete the installation work using only a crane or aerial work vehicle without constructing scaffolding, improving workability. Furthermore, for example, as shown in FIG. 5, by using a covering material 27 (e.g., stone or ceramic siding) that is rich in design, a building with improved design can be realized while realizing high insulation and contributing to energy saving.

[0031] In particular, in the sandwich panel mask system 1 of this embodiment, the adjacent sandwich panels 3 are joined by fitting the convex portion 13 and the concave portion 15, so that the airtightness and heat insulation are high. And, since the support member 5 is fixed inside the fitting portion 17, the support member 5 does not penetrate to the inside of the sandwich panel 3, and the support member 5 can be prevented from becoming a thermal bridge. Therefore, both airtightness and heat insulation can be ensured. Furthermore, since the support member 5 is supported by being sandwiched between the end face 3a of one sandwich panel 3 and the end face 3b of the other sandwich panel 3 at the fitting portion 17, for example, compared to the case where the support member 5 is fixed to the surface of the sandwich panel 3, the support member 5 can be prevented from falling and the fastener 21 can be prevented from coming off, so that the support strength of the support member 5 can be improved. Therefore, the attachment strength of the covering material 7 attached to the support member 5 can be improved while ensuring airtightness and heat insulation.

[0032] In particular, in this embodiment, the support member 5 is a plate-like member bent along the shape of the fitting portion 17. Specifically, the support member 5 is bent to match the surface shape of the protrusion 13 of the sandwich panel 3. This allows the support member 5 to be sandwiched without gaps in the fitting portion 17 and to be closely attached to the protrusion 13, thereby further increasing the support strength of the support member 5. In addition, the curved portion 5d formed at the tip of the fixing portion 5a abuts against the inside of the covering portion 23, which further enhances the effect of preventing the support member 5 from falling over, and significantly improves the support strength of the support member 5.

[0033] In particular, in this embodiment, the fixing portion 5a of the support member 5 is fixed to the structural member 19 by fastening together with the protruding portion 13 by the fastener 21 that penetrates the protruding portion 13 of one sandwich panel 3 inside the fitting portion 17 and fastens to the structural member 19. This allows the support member 5 to be fixed to the structural member 19 of the building rather than to the sandwich panel 3 itself, so that the support member 5 can be fixed more firmly. In addition, since the support member 5 and the sandwich panel 3 are fastened together by a common fastener 21, the number of fasteners can be reduced. Furthermore, since a washer 22 made of rubber or plastic with low thermal conductivity is interposed between the fixing portion 5a of the support member 5 and the head of the fastener 21, the effect of preventing thermal bridges can be further enhanced.

[0034] In particular, in this embodiment, the fixing portion 5a of the support member 5 is covered by the covering portion 23 of the other sandwich panel 3. This allows the gap of the fitting portion 17 to be covered by the covering portion 23, thereby further improving airtightness and heat insulation. In addition, the head of the fixing device 21 can be prevented from being exposed to the outside, which can suppress the fixing device 21 from becoming loose.

[0035] In addition to the above, the methods according to the above embodiments and their modifications may be used in appropriate combination.

[0036] Although not specifically illustrated, the present invention can be implemented with various modifications without departing from the spirit and scope of the present invention. [Explanation of symbols]
