Description

Technical Field

[0001] The present invention relates to a roof structure construction method and a roof structure for forming a roof with folded plates.

Background Art

[0002] Conventionally, there has been proposed a roof structure for forming a roof with folded plates, which has a heat insulation structure or a heat insulation structure on the lower side of the folded plates.

[0003] For example, the heat insulation structure of Patent Document 1 is a heat insulation structure of a concavo-convex material in which a material having a high reflectivity to radiant heat, such as an aluminum foil, is directly attached to the surface of a concavo-convex material. Specifically, it consists of a concavo-convex material whose surface faces the heat source side and in which concave portions located on the heat source side and convex portions located on the non-heat source side are alternately provided, and a material having a high reflectivity to radiant heat, such as an aluminum foil, located on the back side of the concavo-convex material. It is a heat insulation structure in which the material having a high reflectivity to radiant heat, such as the aluminum foil, is attached to only the back surface of the convex portion of the concavo-convex material by an adhesive means, and a space exists between the concave portion and the material having a high reflectivity to radiant heat, such as the aluminum foil.

Problems to be Solved by the Invention

[0005] However, in the heat insulation structure of Patent Document 1, it is necessary to adhere a material with a high reflectivity to the back side of the folded plate by an adhesive means, and it is necessary to work facing upward at a high place under the folded plate. The preparation for that work is complicated, and the work itself is heavy labor.

[0006] This invention has been made in view of these circumstances, and aims to provide a roof structure construction method and a roof structure that can easily construct a heat-shielding structure or an insulating structure on the underside of a corrugated sheet. [Means for solving the problem]

[0010] The roof structure construction method described in claim 4 is characterized in that, in addition to the configuration of claim 3, the step of arranging the corrugated sheet material directly beneath the corrugated sheet material involves bending the long side of the corrugated sheet material directly beneath the corrugated sheet material to form a connecting piece, and then connecting the connecting pieces of adjacent corrugated sheet material directly beneath the corrugated sheet material by bringing them into contact with each other.

[0011] The roof structure according to claim 5 is characterized by comprising beam members constituting the roof, a thin plate-like corrugated sheet material placed on the beam members and having at least one of the properties of heat shielding or heat insulation, and a corrugated sheet provided above the corrugated sheet material and fixed to the beam members.

FIG. 1 is an explanatory diagram showing an example of a roof structure according to the present invention. FIG. 2 is an explanatory diagram showing a state in which a tight frame is provided on a beam member of the roof structure.

[0017] The invention of the present application relates to a roof structure construction method and a roof structure 1 in which a roof is formed by a folded plate 10. As the roof structure 1, there are beam members 12, 14, 16, 18 constituting the roof, and folded plate direct materials 30, 32, 34, 36, 40, 42, 44, 46 which are thin plate-shaped and have at least one of heat insulation or heat insulation properties and are arranged on the beam members 12, 14, 16, 18, and a folded plate 10 provided above the folded plate direct materials 30, 32, 34, 36, 40, 42, 44, 46 and fixed to the beam members 12, 14, 16, 18.

[0018] Further, the folded plate direct materials 30, 32, 34, 36, 40, 42, 44, 46 only need to be thin plate-shaped and have at least one of heat insulation or heat insulation properties, and are not limited by the material. As the folded plate direct materials 30, 32, 34, 36, 40, 42, 44, 46, for example, those having a high reflectivity aluminum sheet on the surface on the folded plate 10 side and a heat insulating material sheet under the aluminum sheet, or those in which the upper and lower surfaces of a polyester non-woven fabric are covered with a glass cloth can be used.

[0019] Furthermore, the straight members 30, 32, 34, 36, 40, 42, 44, 46 below the folded plates may have a long shape with a predetermined width. As for the arrangement of the straight members 30, 32, 34, 36, 40, 42, 44, 46 below the folded plates, a plurality of the straight members 30, 32, 34, 36, 40, 42, 44, 46 may be arranged such that they are parallel to each other along the folding direction of the folded plate 10.

[0020] Furthermore, when a plurality of the straight members 30, 32, 34, 36, 40, 42, 44, 46 below the folded plates are arranged such that they are parallel to each other along the folding direction of the folded plate 10, the long sides of the straight members 30, 32, 34, 36, 40, 42, 44, 46 may be bent to form connecting pieces 30a, 30b, 32a, 32b, 34a, 34b, 36a, 36b, 40a, 40b, 42a, 42b, 44a, 44b, 46a, 46b, and the connecting pieces 30a, 30b, 32a, 32b, 34a, 34b, 36a, 36b, 40a, 40b, 42a, 42b, 44a, 44b, 46a, 46b of the adjacent straight members 30, 32, 34, 36, 40, 42, 44, 46 below the folded plates may be made to contact and connect with each other.

[0021] Furthermore, a space is provided between the folded plate 10 and the straight members 30, 32, 34, 36, 40, 42, 44, 46 below the folded plates so that they do not contact each other.

[0022] Next, the construction method of the roof structure of the present application will be described. First, as shown in FIG. 2, for the construction of the roof structure 1 formed by the folded plate 10, as the framework of the roof, beam members 12, 14, 16, 18 made of steel are assembled in a frame shape. Then, on the upper surfaces 16a, 18a of the beam members 16 and 18 that are opposite and parallel to each other, tight frames 20, 22, which are corrugated strip-shaped metal fittings along the waveform of the folded plate 10 on which the folded plate 10 is placed and fixed, are fixed. So far, the construction of the roof structure 1 formed by the folded plate 10 is common.

[0023] Next, as shown in Figure 3, a thin, plate-like corrugated sheet material 30 having at least one of the properties of heat shielding or heat insulation is placed on the upper surfaces 16a and 18a of the beam members 16 and 18 that constitute the roof (corrugated sheet material placement step). In actual work, it is sufficient to simply place the corrugated sheet material 30 so that it rests on the upper surfaces 16a and 18a of the beam members 16 and 18.

[0024] The corrugated sheet direct support member 30 shown in Figure 3 is a long, elongated shape with a predetermined width. As shown in Figure 4, multiple corrugated sheet direct support members 32, 34, 36, 40, 42, 44, and 46 are arranged in parallel on the upper surfaces 16a and 18a of the beam members 16 and 18 (the corrugated sheet direct support members 30, 32, 34, 36, 40, 42, 44, and 46 are arranged parallel to each other along the direction of the folds of the corrugated sheet 10). It is not necessary to use multiple corrugated sheet direct support members 30, 32, 34, 36, 40, 42, 44, and 46; one large-area piece may be used, or multiple square-shaped pieces may be used instead of elongated pieces. The corrugated sheet direct support member 30 and the corrugated sheet direct support members 32, 34, 36, 40, 42, 44, and 46 described later are as described above.

[0025] Furthermore, in the process of arranging the members directly beneath the folded sheet, the members 30, 32, 34, 36, 40, 42, 44, and 46 directly beneath the folded sheet may be arranged so that their edges overlap, but the figures of this application show a different configuration. In the figures of this application, the members 30, 32, 34, 36, 40, 42, 44, and 46 directly beneath the folded sheet are formed by bending their long edges to create connecting pieces 30a, 30b, 32a, 32b, 34a, 34b, 36a, 36b, 40a, 40b, 42a, 42b, 44a, 44b, 46a, and 46b. Then, the connecting pieces 30a, 30b, 32a, 32b, 34a, 34b, 36a, 36b, 40a, 40b, 42a, 42b, 44a, 44b, 46a, 46b of adjacent corrugated sheet members 30, 32, 34, 36, 40, 42a, 42b, 44a, 44b, 46a, 46b are placed in contact with each other. Furthermore, the connecting pieces 30a, 30b, 32a, 32b, 34a, 34b, 36a, 36b, 40a, 40b, 42a, 42b, 44a, 44b, 46a, 46b of adjacent corrugated sheet members 30, 34, 36, 40, 42, 44, 46b that are facing each other are connected.

[0026] As for connecting (fixing) adjacent corrugated sheet direct underlayment 30, 32, 34, 36, 40, 42, 44, 46 pieces 30a, 30b, 32a, 32b, 34a, 34b, 36a, 36b, 40a, 40b, 42a, 42b, 44a, 44b, 46a, 46b to each other, one method is to stick them together with double-sided tape or adhesive, but it is possible to install them more easily by fastening them with a stapler or by connecting (fixing) them by clamping them with clip-like objects.

[0027] In the state shown in Figures 4 to 6 (the state after the corrugated sheet direct support material placement process), the corrugated sheets 10 are installed on top of the placed corrugated sheet direct support materials 30, 32, 34, 36, 40, 42, 44, and 46, and the corrugated sheets 10 are fixed to the beam materials 16 and 18 (corrugated sheet installation process). This completes the roof structure 1, which forms the roof with the corrugated sheets 10. Note that a space should be left between the corrugated sheets 10 and the corrugated sheet direct support materials 30, 32, 34, 36, 40, 42, 44, and 46 so that they do not come into contact.

[0028] Alternatively, the procedure could be to place all the corrugated sheet base members 30, 32, 34, 36, 40, 42, 44, and 46 and complete the corrugated sheet base member placement process, then install the corrugated sheet 10 and fix it to the beam members 16 and 18 to perform the corrugated sheet installation process. However, as shown in Figure 7, it is also possible to place at least one corrugated sheet base member 46 in the corrugated sheet base member placement process, and then, as shown in Figure 8, fix at least one corrugated sheet 10 in the corrugated sheet installation process, and perform the corrugated sheet base member placement process and the corrugated sheet installation process alternately. By performing the corrugated sheet base member placement process and the corrugated sheet installation process alternately, it becomes possible to use the already fixed corrugated sheet 10 as a scaffold and place the next corrugated sheet base member 44 next to the already placed corrugated sheet base member 46, thereby eliminating the need for scaffolding and improving work efficiency.

[0029] According to the roof structure construction method and roof structure 1 described above, which form a roof using the folded sheet 10, a heat-shielding structure or an insulating structure can be easily constructed on the underside of the folded sheet.

[0030] This invention allows for various embodiments and modifications without departing from the broad spirit and scope of the invention. Furthermore, the embodiments described above are for illustrative purposes only and do not limit the scope of the invention. In other words, the scope of the invention is indicated by the claims, not by the embodiments. Various modifications made within the scope of the claims and the equivalent scope of the meaning of the invention are considered to be within the scope of this invention. [Industrial applicability]
