Description

[Technical Field]

[0001] The present invention relates to outdoor structures such as carports and entrances and to construction methods thereof, and more particularly to a support structure for roofing materials that constitute a roof and a construction method thereof. [Background technology]

[0002] In outdoor structures where the roof is constructed by disposing roofing materials between edge building materials such as frames, both end edges of the plate-shaped roofing materials are placed in respective storage compartments for the edge building materials. The edge building materials are supported in the storage compartments so as to sandwich both the front and back sides of the roofing material, and are capable of moving relative to each other in a direction along the surface of the roofing material. With this type of outdoor structure, even if the roofing material undergoes thermal expansion and contraction due to the effects of, for example, solar radiation, this is absorbed by the roofing material moving appropriately along the surface, eliminating the risk of problems such as out-of-plane deformation of the roofing material (see, for example, Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-30005 Summary of the Invention [Problem to be solved by the invention]

[0004] However, after placing the edge of the roofing material in the edge building material storage section, it becomes difficult to confirm the position of the roofing material relative to the edge building material. For this reason, if the roofing material is assembled in a state where it is positioned offset relative to the edge building materials on both sides, there is a concern that thermal expansion will occur and the roofing material will fall off one of the edge building materials. In particular, in outdoor structures using roofing materials with a long overall length, the amount of thermal expansion will be large, and the above-mentioned problem will be more pronounced.

[0005] In view of the above circumstances, the present invention provides a roofing material that can prevent the roofing material from falling off from the edge building material. Outdoor structures The purpose is to provide. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the outdoor structure of the present invention is an outdoor structure in which a roof is formed by placing both end edges of plate-shaped roofing materials in respective storage portions of edge building materials, and supporting building materials are arranged between the edge building materials, and both end edges of the roofing materials are arranged in the storage portions of the edge building materials, and the storage portions are formed by providing hook portions on the edge building materials, and the hook portions have hook plate portions that are superimposed on the upper surface of the roofing material, and the supporting building materials have sealing members arranged on both side edges of the upper surface, and spacer members arranged between the sealing members, and the roofing material is placed on top of the supporting building material in a state of abutting against the sealing members and the spacer members, and a pressing member is arranged on its upper surface, and the middle part is fixed to the supporting building material by providing a fixing member to the supporting building material via the pressing member, the roofing material, and the spacer member. [Effects of the Invention]

[0008] According to the present invention, both end edges of the roofing material are placed in the storage section of the edge building material, and the middle section is fixed to the supporting building material, so that it is possible to prevent the end edges from falling off from the storage section of the edge building material even if thermal expansion and contraction occurs in the roofing material.

[0009] Furthermore, according to the present invention, the middle part of the roofing material is fixed to the supporting building material, and then both end edges are placed in the storage section of the edge building material. This makes it possible to easily make the position of the roofing material relative to the storage section uniform at both end edges, and makes it possible to prevent the end edges from falling off from the storage section of the edge building material even if thermal expansion and contraction occurs in the roofing material.

[0011] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of an outdoor structure and a construction method thereof according to the present invention will now be described in detail with reference to the accompanying drawings. 1 to 3 show an outdoor structure according to an embodiment of the present invention. The outdoor structure illustrated here is a carport comprising two support columns 10 erected on each side of a parking space S, two beams 11 extending between the support columns 10, and a roof 20 provided on top of the beams 11. This embodiment illustrates a carport suitable for a large parking space S, in which the distance between the left and right support columns 10 is approximately 6 m and two cars can be parked side by side. However, the above dimensions are shown for illustrative purposes only and are not intended to limit the scope of the present invention. Although not explicitly shown in the drawings, the support columns 10 are each rectangular pillar-shaped and are erected vertically by burying their respective lower ends in the ground. The beams 11 are curved so as to be convex upward, and both ends are connected to the upper ends of the left and right support columns 10. In the illustrated example, the beams 11 are curved so that the left and right sides are symmetrical about the convexity. The roof 20 is provided with a frame body 23 formed by framing the left and right gutter frames (edge ​​building materials) 21 and the front and rear side frames 22 all around. The gutter frames 21 and the side frames 22 are extruded shapes formed from a metal such as an aluminum alloy, and are configured to have a substantially uniform cross-sectional shape along the entire longitudinal length.

[0012] As shown in FIG. 4(a), the gutter frame 21 is integrally formed with a frame base 21a and a gutter section 21b provided on the side of the frame base 21a, and is configured linearly along the longitudinal direction. The frame base 21a is rectangular tubular. The gutter section 21b extends outward from the lower end of the frame base 21a at a substantially right angle and then extends upward in a curved manner, opening upward to form a gutter 21c between the frame base 21a and the frame base 21a. The frame base 21a is also provided with a hook section 21d and a support protrusion 21e. The hook section 21d forms a storage section 21f between the frame base 21a and the frame base 21a for storing the end of a roofing material 30 (described later). In this embodiment, hook portion 21d is configured to include first hook plate portion 21d1 protruding outward at a substantially right angle from the upper portion of the outer side surface of frame base 21a between gutter portion 21b, second hook plate portion 21d2 gradually sloping upward outward from first hook plate portion 21d1, third hook plate portion 21d3 extending upward from second hook plate portion 21d2, and fourth hook plate portion 21d4 bending inward at a substantially right angle from third hook plate portion 21d3 toward frame base 21a. As is clear from the figure, fourth hook plate portion 21d4 is positioned above the top surface of frame base 21a and configured to ensure a gap between the edge and the side surface of frame base 21a. Support protrusion 21e protrudes upward from the upper edge of frame base 21a located on the inner side of frame body 23, and then bends outward at a substantially right angle. The upper end surface of support protrusion 21e is located slightly below the lower surface of fourth hook plate portion 21d4.

[0013] The side frames 22 are curved so as to convex upward so as to fit along the beams 11. In this embodiment, as shown in Fig. 5, the side frames 22 are configured to include a side frame main body 22a connected to the gutter frame 21, and a side frame cover 22b attached to the upper part of the side frame main body 22a. A gap (accommodation section) is secured between the upper surface of the portion of the side frame main body 22a located on the inside of the frame body 23 and the lower surface of the portion of the side frame cover 22b located on the inside of the frame body 23, and a sealing member 22c is disposed along the entire length of each of the opposing portions.

[0014] A ridge beam (supporting building material) 24, a plurality of purlins 25, and a plurality of rafters 26 are erected inside the frame 23 formed by the gutter frame 21 and side frames 22, and roofing materials 30 are respectively arranged between the side frames 22 and the rafters 26 and between the rafters 26. The ridge beam 24, purlins 25, and rafters 26, like the gutter frame 21, are extruded shapes formed from a metal such as an aluminum alloy, and each is configured to have a substantially uniform cross-sectional shape along its entire length.

[0015] As shown in Figure 4(b), the ridge beam 24 is hollow and has a rectangular cylindrical cross section, is parallel to the gutter frame 21, and is fixed to the upper surfaces of the uppermost parts of the two beams 11. Sealing members 24a are attached to both sides of the upper surface of the ridge beam 24 over their entire length. A groove-shaped scribe line 24b is formed along the entire length of the middle part of the sealing members 24a on the upper surface of the ridge beam 24.

[0016] As shown in Figure 4(c), the purlins 25 have a square cylindrical cross section with approximately the same external dimensions as the ridge beam 24, and are fixed parallel to the ridge beam 24 at equal intervals on the top surface of the beam 11. A groove-shaped marking line 25a is formed along the entire length of the middle part of the top surface of the purlins 25.

[0017] As shown in Figures 3(b) and 5, the rafters 26 are curved so as to convex upward along the beams 11. In this embodiment, the rafters 26 are configured to include a rafter body 26a fixed to the upper surfaces of the ridge beam 24 and the purlin 25, and a rafter cover 26b attached to the top of the rafter body 26a. The dimensions of the rafter body 26a are configured so that its upper surface approximately coincides with the upper surface of the side frame body 22a. A gap (receiving section) is secured between the upper surfaces of both longitudinal edge portions of the rafter body 26a and the lower surfaces of both longitudinal edge portions of the rafter cover 26b, and sealing members 26c are provided along the entire length of the opposing portions.

[0018] The roofing material 30 is an elastic thin plate configured in a rectangular shape spanning the entire length between the two gutter frames 21. In this embodiment, roofing material 30 made of polycarbonate is used. Both end edges of each roofing material 30 are inserted into the receiving portion 21f of the gutter frame 21, and the roofing material 30 is arranged in a curved state that is convex upward so as to fit along the beam 11. The roofing material 30 between the side frame 22 and the rafter 26 is supported with one side edge sandwiched between the side frame main body 22a and the side frame cover 22b, and the other side edge sandwiched between the rafter main body 26a and the rafter cover 26b. Furthermore, in the portion of the roofing material 30 corresponding to the ridge beam 24, positioning screw members (fixing members) 31 are screwed into the intermediate portion between the side frame 22 and the rafter 26 and the intermediate portion between the rafters 26. That is, as shown in the figure, a spacer member 32 is placed on the upper surface of the ridge beam 24, and then the roofing material 30 is placed on the upper surface of the spacer member 32, and a disk-shaped pressing member 33 is placed on the upper surface of the roofing material 30. The screw members 31 are then screwed into the ridge beam 24 via the pressing member 33, the roofing material 30, and the spacer member 32, thereby fixing the roofing material 30 to the ridge beam 24. Note that the member for fixing the roofing material 30 to the ridge beam 24 is not necessarily limited to the screw members 31, and other fixing members such as nails, bolts, and nuts may also be used.

[0019] 7 to 9 show the procedure for attaching roofing material 30 to the frame body 23. That is, when attaching roofing material 30 to the frame body 23, first, the roofing material 30 is placed on the upper surfaces of the ridge beam 24 and purlins 25, and then, as shown in FIG. 7, the roofing material 30 is positioned relative to the two gutter frames 21. Specifically, the roofing material 30 is positioned so that the insertion amount of the roofing material 30 into the storage portion 21f of the gutter frame 21 is the same dimension d on both sides. At this time, without inserting the roofing material 30 into the storage portion 21f, the edge portion of the roofing material 30 is overlapped on the upper surface of the hook portion 21d relative to the gutter frame 21, and the roofing material 30 is positioned so that the overlap amount between the fourth hook plate portion 21d4 and the roofing material 30 is the same on both sides.

[0020] Next, as shown in Figure 8, the roofing material 30 is fixed to the ridge beam 24 by screwing in the screw members 31. At this time, pilot holes for screwing in the screw members 31 may be pre-formed in the ridge beam 24. When forming pilot holes, if screw insertion holes are pre-formed in the spacer members 32 described above and these screw insertion holes are used as guides, the work of forming pilot holes in the ridge beam 24 will be easier.

[0021] After the roofing material 30 is fixed to the ridge beam 24, as shown in Figure 9, the roofing material 30 is bent and the edge portion is inserted into the storage portion 21f of the gutter frame 21, and then, as shown in Figure 5, the side frame cover 22b is attached to the side frame main body 22a and the rafter cover 26b is attached to the rafter main body 26a, so that the roofing material 30 is supported on all four sides by the frame body 23.

[0022] In the roof 20 configured as described above, the curved central portion of the roofing material 30 is fixed to the ridge beam 24, but the four peripheries of the roofing material 30 are supported by being sandwiched between the gutter frame 21, side frame 22, and rafter 26 via sealing members 22c, 24a, and 26c, respectively. Therefore, even if thermal expansion and contraction occurs in the roofing material 30 due to the effects of sunlight, for example, this is absorbed by the roofing material 30 moving appropriately along the surface, so there is no risk of problems such as the roofing material 30 deforming in an out-of-plane direction.

[0023] Furthermore, the gutter frame 21, which supports both end edges along the length of the roofing material 30, is inserted into each storage section 21f by the same dimension d, so there is no risk of the end edges falling off from the storage section 21f of the gutter frame 21 even if thermal expansion and contraction occurs in the roofing material 30.

[0024] In addition, before fixing the middle part of the roofing material 30 to the ridge beam 24, the roofing material 30 is aligned with each of the gutter frames 21, and then both end edges are placed in the storage section 21f of the gutter frame 21. This makes it possible to easily make the position of the roofing material 30 with respect to the storage section 21f uniform at both end edges, and more reliably prevents the end edges from falling off from the storage section 21f of the gutter frame 21 even if thermal expansion or contraction occurs in the roofing material 30.

[0025] In the above-described embodiment, an example is given of a ridge beam 24 that is molded as a single unit, but it is also possible to configure it with a ridge beam main body 124a that is tubular in shape and a ridge beam cover 124c that has sealing members 124b on both side edges, as in the modified ridge beam 124 shown in Figure 10.

[0026] Furthermore, in the above-described embodiment, roofing materials 30 are arranged in a curved state so as to be convex upward, but this is not necessarily limited to this. Roofing materials may be arranged so that they extend flat from the ridge beam, as in a gable roof. In this case, the edge portions of the roofing materials 30 are not limited to being arranged between the gutter frames 21, but can also be arranged between the ridge beam 24 and the purlins 25, or between the purlins 25. Furthermore, although the gutter frames 21 are arranged equidistant from the ridge beam 24 and parallel to each other, edge building materials may be arranged at different distances from the supporting building materials, or the edge building materials may be arranged at an angle to each other.

[0027] Furthermore, in the above-described embodiment, the storage section 21f is formed by integrally providing the hook section 21d on the frame base 21a, but the storage section may also be formed between separately formed components, such as the side frame 22 and the rafters 26, by connecting them to each other.

[0028] Furthermore, although a carport is exemplified in the above-described embodiment, any other outdoor structure may be used as long as it has a roof.

[0029] As described above, the outdoor structure of the present invention is an outdoor structure in which a roof is formed by placing both end edges of plate-shaped roofing materials in storage portions of edge building materials, and is characterized in that supporting building materials are arranged between the edge building materials, both end edges of the roofing materials are placed in the storage portions of the edge building materials, and the middle portion of the roofing material is fixed to the supporting building materials. According to this invention, both end edges of the roofing material are placed in the storage section of the edge building material, and the middle section is fixed to the supporting building material, so that it is possible to prevent the end edges from falling off from the storage section of the edge building material even if thermal expansion and contraction occurs in the roofing material.

[0030] The present invention is also characterized in that, in the above-mentioned outdoor structure, the supporting building material serves as a ridge beam of the roof, and the roofing material extends gradually downward from the supporting building material toward the edge building material. According to this invention, it is possible to construct a roof for an outdoor structure by providing a single roofing material on both sides of a supporting building material that serves as a ridgepole.

[0031] Furthermore, the present invention is characterized in that, in the outdoor structure described above, the edge building materials are arranged so as to be equidistant from the supporting building materials and parallel to the supporting building materials.

According to this invention, the roofing material is clamped between the spacer member and the clamping member, and a sealing member is interposed between the roofing material and the supporting building material, which has the advantage that there is no risk of the roofing material being damaged due to direct contact with the supporting building material.

[0034] Furthermore, the present invention is characterized in that in the outdoor structure described above, the arrangement dimensions of the roofing material relative to the storage portion of the edge building material are the same at both end edge portions of the roofing material. According to this invention, even if thermal expansion and contraction occurs in the roofing material, it is possible to more reliably prevent the edge portion from falling off from the storage portion of the edge building material.

[0035] Furthermore, the construction method for an outdoor structure according to the present invention is a construction method for an outdoor structure in which a roof is constructed by placing both end edges of a plate-shaped roofing material arranged to cover the top of a supporting building material in a storage portion of the edge building material, and is characterized by including a step of fixing the roofing material to the supporting building material, and a step of placing both end edges of the roofing material after it has been fixed to the supporting building material in the storage portion of the edge building material. According to this invention, the middle part of the roofing material is fixed to the supporting building material, and then both end edges are placed in the storage section of the edge building material. This makes it possible to easily make the position of the roofing material relative to the storage section uniform at both end edges, and makes it possible to prevent the end edges from falling off from the storage section of the edge building material even if thermal expansion and contraction occurs in the roofing material.

[0036] The present invention is also characterized in that, in the construction method for the above-mentioned outdoor structure, it includes a step of positioning both end edges of the roofing material relative to the edge building material before fixing the roofing material to the supporting building material.
