Description

[Technical Field]

[0001] The present invention relates to a temporary fixture for facilitating the construction of a folded-plate roof structure, a folded-plate roof structure using the temporary fixture, and a construction method for a folded-plate roof structure. [Background Art]

[0002] It is known that the cooling efficiency inside a building can be improved by suppressing the temperature rise of a roof. As a method for specifically realizing this effect, the applicant has proposed a heat shielding structure for folded-plate roofs (see Patent Document 1).

[0003] In this heat shielding structure for a folded-plate roof, a heat shielding sheet arranged to form a ventilation path above the folded-plate roof is fixed by using a fastener that is crimped and deformed. The heat shielding sheet forms a shaded area on the folded-plate roof, and ventilation between the sun shading member and the folded-plate roof is achieved, thereby suppressing the temperature rise of the folded-plate roof.

[0004] [Patent Document 1] Japanese Unexamined Patent Publication No. 2017-186817 [Summary of the Invention] [Problems to be Solved by the Invention]

[0005] However, in order to properly construct the above-mentioned heat shielding structure for a folded-plate roof, it is important that the tension (tightness) of the heat shielding sheet is appropriate and the heat shielding sheet has no distortion, and this adjustment requires certain experience. That is, the above-mentioned heat shielding structure for a folded-plate roof has high construction difficulty, and appropriate construction is difficult unless the worker is a skilled constructor.

[0006] Furthermore, if tension or distortion adjustments are unsuccessful and the installation needs to be redone, the fasteners must be removed. However, since the heat-shielding sheets are secured using fasteners that deform by crimping, removing them is not only time-consuming, but the fasteners cannot be reused once removed, making it uneconomical.

[0007] This invention has been made in view of the above circumstances of the past. One of the objects of this invention is to provide a temporary fastener that facilitates the construction of a corrugated metal roof structure, a corrugated metal roof structure using the temporary fastener, and a method for constructing a corrugated metal roof structure. Means for solving the problem and effects of the invention

[0008] A temporary fastener relating to the first aspect of the present invention is a temporary fastener used when indirectly clamping a substantially strip-shaped member, a band portion, which is arranged on the corrugated metal roof body having a shape in which peaks and valleys alternately repeat, to a protruding portion that protrudes upward from the top surface of the peaks and has a constricted portion provided near the top surface, such that its long side substantially intersects with the extending direction of the peaks and valleys, using the fastener, wherein the constricted portion can be detachably clamped via the band portion and clamped by the fastener.

[0009] According to the above configuration, the tension and distortion of the band can be adjusted during the temporary fixing stage (the stage before permanent fixing with the main fastener). Furthermore, since the temporary fastener can temporarily fix the band to the protruding part in a detachable manner, it is easy to redo the temporary fixing, and the temporary fastener can be reused. This reduces the difficulty of constructing corrugated metal roof structures and provides a temporary fastener that enables proper construction even by non-skilled workers.

[0010] Furthermore, since the main fastener is configured to indirectly clamp the band portion via a temporary fastener, even if the main fastener is a metal component that can be crimped and deformed, it will not directly touch the band portion, and the temporary fastener also acts as a cushion, thus preventing damage to the band portion.

[0011] The temporary fixing device according to the second aspect of the present invention comprises a first part that detachably clamps the constricted part via the band, with the protruding part being located inside the C-shaped portion of the Ω shape and the constricted part being located at the opening of the C-shape, and two second parts that are located outside the C-shaped portion of the Ω shape, wherein the first part clamps the constricted part, the vicinity of the boundary between the first part and the second parts can be clamped from the outside of the Ω shape.

[0012] According to the above configuration, when the temporary fastener temporarily secures the strap portion to the protruding portion, the second portion naturally positions itself to cover the strap portion near the protruding portion. This expands the area covered by the temporary fastener, thus preventing damage to the strap portion by the main fastener over a wider area. Furthermore, the second portion guides the protruding portion into the opening, making it easier to attach the temporary fastener. Additionally, pulling the second portion widens the opening, making it easier to remove the temporary fastener.

[0013] A temporary fastener according to a third aspect of the present invention can be configured such that the angle between the two second parts facing the first part is between 90 degrees and 150 degrees.

[0014] According to the above configuration, the temporary fastener has two second parts that spread out in a V-shape from the opening at an appropriate angle. This makes it easier to guide the protruding part into the opening, and further simplifies the installation of the temporary fastener.

[0015] A temporary fastener according to a fourth aspect of the present invention can be configured such that the temporary fastener is made of an elastic material.

[0016] A corrugated metal roof structure according to a fifth aspect of the present invention can be configured to include: a corrugated metal roof body having a shape in which peaks and valleys are alternately repeated; a projection having a constricted portion which is a narrowing provided near the top surface of the peaks; a band portion which is a substantially band-shaped member disposed on the corrugated metal roof body such that its long side substantially intersects the extending direction of the peaks and valleys; a temporary fastener which detachably clamps the constricted portion via the band portion; and a main fastener which, when the temporary fastener is clamping the constricted portion, clamps the temporary fastener and indirectly clamps the band portion with the projection.

[0017] According to the above configuration, the tension and distortion of the band can be adjusted during the temporary fixing stage (the stage before permanent fixing with the main fastener). Furthermore, since the temporary fastener can temporarily fix the band to the protruding part in a detachable manner, it is easy to redo the temporary fixing, and the temporary fastener can be reused. As a result, it is possible to provide a corrugated metal roof structure that is easy to install and can be properly installed even by inexperienced installers.

[0018] Furthermore, since the main fastener is configured to indirectly clamp the band portion via a temporary fastener, even if the main fastener is a metal component that can be crimped and deformed, it will not directly touch the band portion, and the temporary fastener also acts as a cushion, thus preventing damage to the band portion.

[0019] The corrugated metal roof structure according to the sixth aspect of the present invention comprises a first part that detachably clamps the constricted part via the band, with the protruding part being located inside the C-shaped portion of the Ω shape and the constricted portion being located at the opening of the C-shape, and two second parts that correspond to the parts of the Ω shape other than the C shape, wherein the first part clamps the constricted portion, the vicinity of the boundary between the first part and the second parts can be clamped from the outside of the Ω shape by the main fixing device.

[0020] According to the above configuration, when the temporary fastener temporarily secures the strap portion to the protruding portion, the second portion naturally positions itself to cover the strap portion near the protruding portion. This expands the area covered by the temporary fastener, thus preventing damage to the strap portion by the main fastener over a wider area. Furthermore, the second portion guides the protruding portion into the opening, making it easier to attach the temporary fastener. Additionally, pulling the second portion widens the opening, making it easier to remove the temporary fastener.

[0021] A corrugated metal roof structure according to the seventh aspect of the present invention can be configured such that the angle between the two second parts facing the first part in the temporary fastener is 90 degrees to 150 degrees.

[0022] According to the above configuration, the temporary fastener has two second parts that spread out in a V-shape from the opening at an appropriate angle. This makes it easier to guide the protruding part into the opening, and further simplifies the installation of the temporary fastener.

[0023] The corrugated metal roof structure according to the eighth aspect of the present invention can be configured such that the temporary fastener is made of an elastic material.

[0024] A construction method for a folded plate roof structure according to the ninth aspect of the present invention can be configured to include: an arrangement step of arranging a band portion, which is a substantially band-shaped member, on a folded plate roof body having a shape in which peaks and valleys are alternately repeated, such that the longer side substantially intersects with the extending direction of the peaks and valleys; a temporary fixing step of using a temporary fastener to detachably clamp a constricted portion, which is a narrowing provided near the top surface of a protruding portion that protrudes upward from the top surface of the peak, via the band portion; and a final fixing step of clamping the temporary fastener with a permanent fastener and indirectly clamping the band portion to the protruding portion.

[0025] According to the above configuration, the tension and distortion of the belt portion can be adjusted in the temporary fixing step (the step before the main fixing by the main fixture is performed). Further, since the temporary fixture can temporarily fix the belt portion to the protruding portion in a detachable manner, redoing the temporary fixation is easy, and the temporary fixture can also be reused. Accordingly, it is possible to provide a construction method for a folded-plate roof structure that has low construction difficulty and allows appropriate construction even by non-skilled constructors.

[0026] Further, since the main fixture is configured to indirectly clamp the belt portion via the temporary fixture, even if the main fixture is a metal member that can be crimped and deformed, the main fixture does not directly contact the belt portion, and the temporary fixture also serves as a cushion, so damage to the belt portion can be prevented.

[0027] In the construction method for a folded-plate roof structure according to the tenth aspect of the present invention, the temporary fixture has a substantially Ω-shaped cross-section, and comprises: a first portion corresponding to the C-shaped part of the Ω-shape, wherein the protruding portion is disposed inside the C-shape, the constricted portion is disposed at the opening of the C-shape, and the first portion detachably clamps the constricted portion via the belt portion; and two second portions corresponding to parts other than the C-shaped part of the Ω-shape, and in a state where the first portion clamps the constricted portion, the vicinity of the boundary between the first portion and the second portion can be configured to be clamped by the main fixture from the outside of the Ω-shape.

[0028] According to the above configuration, when the temporary fixture temporarily fixes the belt portion to the protruding portion, the second portions are naturally arranged to cover the belt portion near the protruding portion. This expands the range in which the temporary fixture covers the belt portion, and can prevent damage to the belt portion caused by the main fixture over a wider range. Further, since the second portions can guide the protruding portion to the opening, attachment of the temporary fixture becomes easier. Furthermore, pulling the second portions widens the opening, so removal of the temporary fixture becomes easier.

[0029] In the construction method for a folded-plate roof structure according to the eleventh aspect of the present invention, in the temporary fixture, the angle between the two second portions on the side opposite to the first portion can be configured to be 90 degrees to 150 degrees.

[0030] According to the above configuration, the temporary fastener has two second parts that spread out in a V-shape from the opening at an appropriate angle. This makes it easier to guide the protruding part into the opening, and further simplifies the installation of the temporary fastener.

[0031] A construction method for a corrugated metal roof structure according to the 12th aspect of the present invention can be configured such that the temporary fastener is made of an elastic material. [Brief explanation of the drawing]

[0033] Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments shown below are illustrative examples for realizing the technical concept of the present invention, and the present invention is not limited to these. Furthermore, this specification does not limit the members shown in the claims to the members of the embodiments. In particular, the dimensions, materials, shapes, relative arrangements, etc. of the components described in the embodiments are not intended to limit the scope of the present invention to those, unless otherwise specifically stated, but are merely illustrative examples. Note that the size and positional relationships of the members shown in each drawing may be exaggerated for clarity of explanation. Furthermore, in the following description, the same name and reference numerals indicate the same or similar members, and detailed explanations are omitted as appropriate. Furthermore, each element constituting the present invention may be configured such that multiple elements are made of the same material, with one material serving multiple elements, or conversely, the function of one material may be shared among multiple materials. Furthermore, the function or processing of each element constituting the present invention may be realized by artificial intelligence (AI) to the extent possible. [Folded plate roof structure 1]

[0034] As shown in Figure 1, the corrugated metal roof structure 1 according to one embodiment of the present invention mainly consists of a corrugated metal roof body 11, a protruding portion 12, a band portion 13, a temporary fastener 14, and a permanent fastener 15. Each component will be described below. [Folded plate roof body 11]

[0035] As shown in Figures 1 and 2, the corrugated metal roof body 11 is a member with a shape in which peaks 111 and valleys 112 are alternately repeated, and has a projection 12 that protrudes upward from the top surface of the peak 111.

[0036] The installation location and method of the corrugated metal roof body 11 are not particularly limited, but for example, the corrugated metal roof body 11 can be installed on the building by fixing a metal fitting called a tight frame to the beam of the building and fixing the corrugated metal roof body 11 to the tight frame. [Protrusion 12]

[0037] As shown in Figures 1 and 2, the protruding portion 12 is a member provided to protrude upward from the top surface of the peak portion 111 of the corrugated metal roof body 11, and has a constricted portion 121 which is a narrowing provided near the top surface of the peak portion 111.

[0038] The protruding portion 12 is not particularly limited to other forms, as long as it has a constricted portion 121 that can be clamped by the temporary fastener 14. For example, when using an existing standing seam type corrugated metal roof as the corrugated metal roof body 11, the seams (parts of the corrugated metal roof members that connect adjacent corrugated metal roof members and connect to fasteners such as tight frames) can be reused as the protruding portion 12. [Band section 13]

[0039] As shown in Figures 1 and 2, the band portion 13 is a roughly band-shaped member placed on the corrugated metal roof body 11, and is positioned on the corrugated metal roof body 11 such that its long side roughly intersects with the extending directions of the peaks 111 and valleys 112. In addition, multiple band portions 13 are arranged side by side so as to cover the entire upper surface of the corrugated metal roof body 11.

[0040] With the aforementioned configuration, even with the same width of strip sections 13, the number of strip sections arranged side by side can be adjusted to create a corrugated metal roof body 11 of various sizes. Furthermore, while the size (width) of the strip sections 13 is not particularly limited, a relatively narrow width is preferable, specifically, a width of approximately 100 mm to 500 mm, and more preferably 300 mm. As mentioned above, a narrower width makes it easier to adjust the number of strip sections 13 to match the corrugated metal roof body 11. In addition, there is the advantage of being able to reduce costs when it becomes necessary to replace damaged strip sections 13 due to aging or other reasons.

[0041] Furthermore, the material and other properties of the band portion 13 are not particularly limited, but if materials with specific characteristics are used, those characteristics can be imparted to the corrugated metal roof structure 1.

[0042] For example, if a heat-shielding sheet having heat-blocking properties is used as the band portion 13, the heat-blocking properties are imparted to the corrugated metal roof structure 1, improving the cooling efficiency inside the building. The heat-shielding sheet consists of a deformable mesh sheet formed by weaving warp and weft threads, and can be used that has at least enough deformation to flutter in the wind. As it is a mesh sheet, it also has water permeability, breathability, and ventilation. In addition, suitable materials such as monofilaments or flat yarns made of synthetic resins or natural materials can be used for the warp and weft threads. It is preferable that the material has excellent weather resistance, durability, and antistatic properties, and a black color is preferable as it has a higher sun-shading effect. A reflective layer may be provided on the surface exposed to sunlight. The reflective layer can be formed by laminating a film or by metal vapor deposition.

[0043] Furthermore, for example, if a thin-film solar power generation sheet is used as the strip portion 13, it will block heat, improve the cooling efficiency inside the building, and generate electricity at the same time.

[0044] The band portion 13 is not limited to the above-described configuration. Furthermore, the band portion 13 does not necessarily need to cover the entire upper surface of the corrugated metal roof body 11; it may cover only a portion of the upper surface of the corrugated metal roof body 11. [Temporary fastening device 14]

[0045] As shown in Figures 1 and 2, the temporary fastener 14 is a member that detachably clamps the constricted portion 121 via the band portion 13. Furthermore, the temporary fastener 14 is clamped by the main fastener 15 while the constricted portion 121 is clamped via the band portion 13. In short, the temporary fastener 14 is a member for temporarily fixing the band portion 13 to the corrugated metal roof body 11.

[0046] Specifically, during the construction process of the corrugated metal roof structure 1, there is a temporary fixing stage (a stage before permanent fixing by the permanent fixing device) in which the temporary fastener 14 clamps the constricted portion 121 via the band portion 13, and is not clamped by the permanent fastener 15. At this time, the tension and distortion of the band portion 13 can be adjusted. In addition, since the temporary fastener 14 can temporarily fix the band portion 13 to the protruding portion 12 in a detachable manner, it is easy to redo the temporary fixing, and the temporary fastener 14 can be reused. This reduces the difficulty of constructing the corrugated metal roof structure and enables proper construction even by workers who are not highly skilled.

[0047] Furthermore, since the main fastener 15 is configured to indirectly clamp the band portion 13 via the temporary fastener 14, the main fastener 15, which is a metal member that can be deformed by crimping, does not directly touch the band portion 13, and the temporary fastener also acts as a cushion, thus preventing damage to the band portion. For example, in the technology disclosed in Patent Document 1, a cushioning sheet material is provided on the inner surface of the fastener (a member corresponding to the opening in this invention) to prevent damage to the heat shielding sheet (a member corresponding to the band portion 13 in this invention), but this is unnecessary in this invention.

[0048] Furthermore, as shown in Figure 3, the temporary fixing device 14 is a member with a roughly Ω-shaped cross-section, consisting of a first part 141 corresponding to the C-shaped portion of the Ω shape and two second parts 142 corresponding to the non-C-shaped portion, and is made of an elastic material.

[0049] As described above, in the configuration shown in Figure 4, the temporary fixing device 14 has a projection 12 positioned inside the C-shape of the first part 141, and a constricted portion 121 positioned at the opening of the C-shape of the first part 141, allowing the first part 141 to detachably clamp (temporarily fix) the constricted portion 121 via the band portion 13. Furthermore, as shown in Figures 1 and 2, when the first part 141 is clamping the constricted portion 121, the temporary fixing device 14 is clamped from the outside of the Ω shape near the boundary between the first part 141 and the second part 142 by the main fixing device 15.

[0050] In the case of the aforementioned shape, as shown in Figure 4, when the temporary fastener 14 temporarily fixes the band portion 13 to the protruding portion 12, the second portion 142 naturally becomes positioned to cover the band portion 13 near the protruding portion 12. This expands the area over which the temporary fastener 14 covers the band portion 13, and prevents damage to the band portion 13 by the main fastener 15 over a wider area.

[0051] Furthermore, as shown in Figure 3, the temporary fastener 14 has two second parts 142 that spread out in a V-shape from the opening, so the second parts 142 can guide the protruding part 12 into the opening, making it easier to attach the temporary fastener 14.

[0052] In this case, it is more preferable that the angle between the first part 141 and the two second parts 142 on the opposite side (the lower angle in Figure 3) is between 90 and 150 degrees. This is because the two second parts 142 spread out at an appropriate angle, making it easier to guide the protruding part 12 into the opening and further facilitating the installation of the temporary fastener 14. If the angle is greater than 150 degrees, the guidance into the opening will be weaker compared to when it is smaller. Also, if the angle is less than 90 degrees, it will be more difficult to insert the protruding part 12 between the two second parts 142 compared to when it is larger.

[0053] Furthermore, in the temporary fixing state shown in Figure 4, pulling the second part 142 widens the opening, making it easier to remove the temporary fixing device 14.

[0054] The form of the temporary fastener 14 is not limited to those described above. In short, the temporary fastener 14 only needs to be able to temporarily fix the band portion 13 to the corrugated metal roof body 11 in a detachable manner, and prevent the main fastener 15 from directly clamping the band portion 13. Its shape and material can be changed as appropriate. [Main fixture 15]

[0055] The fastener 15 is a metal member that can be crimped and deformed, and as shown in Figures 1 and 2, it is a member that clamps (permanently fixes) the temporary fastener 14, which is in a state where the band portion 13 is temporarily fixed to the corrugated roof body 11, from the outside. In short, the fastener 15 is a member for permanently fixing the band portion 13 to the corrugated roof body 11.

[0056] More specifically, the main fastener 15 is a component that is used by crimping and deforming it from the outside of the temporary fastener 14 so as to clamp the vicinity of the boundary between the first part 141 and the second part 142. In other words, the main fastener 15 can indirectly clamp the band part 13 by clamping the temporary fastener 14.

[0057] Conventional technologies, such as those shown in Patent Document 1, have problems such as being uneconomical because they use fasteners that deform under crimping, which makes removal time-consuming if tension or distortion adjustment is failed and the construction needs to be redone, and furthermore, the fasteners cannot be reused once removed.

[0058] In contrast, the corrugated metal roof structure 1 according to the present invention is configured to allow temporary fixing using a temporary fastener 14 before permanent fixing. Therefore, the tension and distortion of the band portion 13 can be adjusted at the temporary fixing stage before permanent fixing, thus eliminating the need to redo the construction. As a result, even if the permanent fastener 15 is a metal member that can be deformed by crimping, as shown in Patent Document 1, the aforementioned problems are unlikely to occur.

[0059] The form of the fastener 15 is not limited to those described above, and the band portion 13 may be permanently fixed to the corrugated roof body 11 by means other than crimping deformation. [Construction method for corrugated metal roof structure 1]

[0060] The construction method for the corrugated metal roof structure 1 according to the present invention consists of a placement step ST101, a temporary fixing step ST102, and a permanent fixing step ST103, as shown in the flowchart of Figure 5. Each step will be described below. [Placement process ST101]

[0061] The arrangement process ST101 is the process of placing the strip sections 13 on the corrugated roof body 11. The strip sections 13 are placed on the corrugated roof body 11 such that their longer sides substantially intersect with the extension directions of the peaks 111 and valleys 112. In addition, multiple strip sections 13 are placed side by side so as to cover the entire upper surface of the corrugated roof body 11.

[0062] Furthermore, the arrangement of the strip portion 13 is not limited to the above-described configuration, and it is not necessarily required that it be arranged to cover the entire upper surface of the corrugated metal roof body 11. [Temporary fixing process ST102]

[0063] As shown in Figure 4, the temporary fixing step ST102 is a step in which the constricted portion 121 is detachably clamped via the band portion 13 using a temporary fixing device 14. In short, the temporary fixing step ST102 is a step in which the band portion 13 is temporarily fixed to the corrugated roof body 11 using the temporary fixing device 14.

[0064] During the temporary fixing process ST102, the installer can adjust the tension and distortion of the band portion 13. Furthermore, since the temporary fixing device 14 can temporarily fix the band portion 13 to the protruding portion 12 in a detachable manner, it is easy to redo the temporary fixing, and the temporary fixing device 14 can also be reused. This reduces the difficulty of constructing the corrugated metal roof structure, making it possible for even inexperienced installers to perform proper construction. [Main fixing process ST103]

[0065] As shown in Figure 1, the main fixing step ST103 is a step in which the temporary fixing device 14 is clamped with the main fixing device 15, and the band portion 13 is indirectly clamped on the protruding portion 12. In short, the main fixing step ST103 is a step in which the band portion 13 is temporarily fixed to the corrugated metal roof body 11 using the main fixing device 15.

[0066] Since the tension and distortion of the band portion 13 are adjusted during the temporary fixing process ST102, the construction method for the folded plate roof structure 1 according to the present invention is configured so that the main fixing process ST103 does not need to be redone.

[0067] Furthermore, since the main fastener 15 is configured to indirectly clamp the band portion 13 via the temporary fastener 14, the main fastener 15, which is a metal component that can be deformed by crimping, does not directly touch the band portion 13, and the temporary fastener also acts as a cushion, thus preventing damage to the band portion.
