Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above roof structure, the folded plate is visible from below. Therefore, when reforming the roof structure, a soffit material such as a ceiling panel may be added below the folded plate from the viewpoint of appearance quality. That is, if a reform is carried out such that a reinforcing member is attached to the upper surface of the beam, a base material is attached to the reinforcing member, and the soffit material is supported by the reinforcing member via the base material, it becomes difficult to visually recognize the folded plate from below, which is advantageous in terms of appearance quality. When attaching a reinforcing member to the upper surface of the beam, a joining member may be provided. For example, by interposing a joining member having a beam contact flat plate portion that contacts the side surface of the beam and a reinforcing member contact flat plate portion that contacts the lower surface of the reinforcing member, it becomes possible to attach the reinforcing member to the upper surface of the beam.

[0005] Incidentally, the roof structures subject to renovation have various cross-sectional beam shapes, and some, for example, have protrusions at the corners. These protrusions are designed to abut against the mounting base when the beam is placed, preventing the beam's surface from coming into contact with the base. In the case of beams with these protrusions, even when additional processing such as cutting is performed on the beam after extrusion molding, the surface does not come into direct contact with the processing base, thus preventing damage such as scratches on the surface caused by contact with processing debris. However, with beams that have protrusions, it may be difficult to attach reinforcing materials because the beam contact plate portion of the joining member cannot be brought into contact with the side of the beam without any gaps.

[0006] In view of the above circumstances, the present invention aims to provide a roof structure that allows reinforcing materials to be reliably attached to the upper surface of beams even during renovations. [Means for solving the problem]

[0007] To achieve the above objective, the roof structure according to the present invention is a roof structure in which a reinforcing member is attached to the upper surface of a beam via a connecting member, wherein the connecting member has a first flat plate portion that abuts against the side surface of the beam and a second flat plate portion that abuts against the lower surface of the reinforcing member, and also has a connecting plate portion that connects the first flat plate portion and the second flat plate portion while being separated from the side surface of the beam. [Effects of the Invention]

[0008] According to the present invention, even if there is a protrusion at the corner of an already installed beam, the connecting plate allows the first flat plate to abut against the side surface of the beam without contacting the protrusion, and it is possible to reliably attach the reinforcing material to the upper surface of the beam via the connecting member during renovations. [Brief explanation of the drawing]

[Figure 7] Figure 1 is a longitudinal cross-sectional view showing the connection between the carport's joint member and the reinforcing material. [Figure 8] This is a longitudinal cross-sectional view showing the connection between the beam, reinforcing material, and connecting member of a carport, which is a modified example of the present invention. [Modes for carrying out the invention]

[0010] Hereinafter, preferred embodiments of the roof structure according to the present invention will be described in detail with reference to the attached drawings.

[0011] Figures 1 to 5 show a carport, an outdoor structure to which the roof structure according to an embodiment of the present invention is applied. The carport illustrated here is constructed by remodeling an already installed carport. The existing carport illustrated as the target of remodeling in this embodiment has a roof structure 1 mounted on top of four columns 10. The columns 10 are formed from a metal such as an aluminum alloy and are configured, for example, in the shape of a square tube. These columns 10 are erected, for example, two on each side edge of the parking space. The projection dimensions of each column 10 from the ground are approximately equal to each other. Note that the cross-section of the columns 10 does not necessarily have to be square.

[0012] The roof structure 1 is composed of beams 20 and corrugated sheets 30. The beams 20 are constructed from a metal such as an aluminum alloy so that their cross-section is a rectangular tube. The two beams 20 have their upper surface 20a and lower surface 20b extending horizontally, and their two side surfaces 20c and 20d extending vertically. Although not explicitly shown in the figure, the two beams 20 are configured to be at different heights. Each of the four corners of the beams 20 is provided with a protrusion 20e. The protrusions 20e are provided to project laterally from both corners on the upper surface 20a side of the beam 20, and to project laterally and downward from both corners on the lower surface 20b side of the beam 20. The beams 20 having the above configuration are arranged to span approximately horizontally between the upper ends of the two columns 10.

[0013] The corrugated sheet 30 is a surface material provided with an upper wall portion 30a, an inclined wall portion 30b, and a lower wall portion 30c in a sequential continuous manner, and is formed from metal such as plated steel sheet. The length and width dimensions of the corrugated sheet 30 are set to a size that can almost completely cover the parking space. The corrugated sheet 30 is supported on the upper surface 20a of each beam 20 via a tight frame 31. More specifically, the corrugated sheet 30 is supported on the upper surface 20a of the beam 20 such that the curved lines between the upper wall portion 30a and the inclined wall portion 30b, and the curved lines between the lower wall portion 30c and the inclined wall portion 30b, are perpendicular to the extending direction of the beam 20. The tight frame 31 is a narrow member formed with an upper surface portion 31a, an inclined surface portion 31b, and a lower surface portion 31c in a sequential continuous manner so that it can be superimposed on the upper surface of the corrugated sheet 30, and is arranged along the longitudinal side of the beam 20. The tight frame 31 and the corrugated sheet 30 are connected by, for example, inserting a screw member 31d provided on the tight frame 31 into the upper wall portion 30a of the corrugated sheet 30 and then screwing a nut member 32 onto the screw member 31d. As described above, the two beams 20 are configured to be of different heights. Therefore, the corrugated sheet 30, which is laid across the two beams 20, is arranged in a sloping manner, gradually decreasing in height from the taller beam 20 to the shorter beam 20. The four perimeter ends of the corrugated sheet 30 are each covered with fascia boards 33.

[0014] The renovation work to be carried out on this carport includes installing soffit material 40 below the corrugated metal sheet 30. More specifically, reinforcing members 50 are installed between the beams 20, a base material 60 is provided on the lower surface 50a of the reinforcing members 50, and the soffit material 40 is attached to the base material 60.

[0015] The reinforcing members 50 are arranged to span between the upper surfaces 20a of the two beams 20, extending in a direction perpendicular to the longitudinal direction of the beams 20, and are attached to the beams 20 via connecting members 51. The base material 60 extends along the longitudinal direction of the beams 20 and is attached to span across the lower surfaces 50a of the multiple reinforcing members 50. The soffit material 40 is configured to form a plate shape and multiple pieces are attached to the lower surface of the base material 60 so as to cover the entire lower area of ​​the corrugated sheet 30. In the illustrated example, multiple reinforcing members 50 are arranged between the beams 20. The reinforcing members 50 have a rectangular cross-section and form a cylindrical shape. The joining member 51 has a first flat plate portion 51a that abuts against the side surface 20c of the beam 20 and a second flat plate portion 51b that abuts against the lower surface 50a of the reinforcing member 50, and is provided between the side surface 20c of the beam 20 located on the higher side of the inclined folded plate 30 and the lower surface 50a of the reinforcing member 50. The first flat plate portion 51a and the second flat plate portion 51b are each configured to be flat. The first flat plate portion 51a is provided with a plurality of screw insertion holes (connector insertion holes) 51c that are at different height positions from each other.

[0016] Here, as described above, if the beam 20 of the carport to be renovated has a protrusion 20e, the protrusion 20e gets in the way, making it difficult to bring the first flat plate portion 51a of the joining member 51 into contact with the side surface 20c of the beam 20 without any gaps, and it may also be difficult to install the reinforcing material 50, the base material 60, and the soffit material 40. Therefore, in this embodiment, as shown in Figures 6 and 7, a connecting plate portion 51d is provided between the first flat plate portion 51a and the second flat plate portion 51b of the joining member 51 to solve the above problem. That is, when the first flat plate portion 51a is brought into contact with the side surface 20c of the beam 20, the connecting plate portion 51d of the joining member 51 bends in a direction away from the side surface 20c of the beam 20, then extends upward, and the extended edge is continuous with one side edge of the second flat plate portion 51b. In the connecting plate portion 51d, a gap larger than the protruding dimension of the convex portion 20e provided on the beam 20 is secured between the outer surface 51e facing the side surface 20c of the beam 20 and the first contact surface 51f in the first flat plate portion 51a that abuts against the side surface 20c of the beam 20. The extension direction of the second flat plate portion 51b relative to the first flat plate portion 51a is set to be greater than 90°, corresponding to the inclination angle of the folded plate 30 described above.

[0017] If the joint member 51 configured as described above is applied, even when the convex portion 20e is provided on the beam 20 of the carport to be renovated, the first contact surface 51f of the first flat plate portion 51a can be brought into contact with the side surface 20c of the beam 20 without a gap at a portion below the convex portion 20e. Thus, if the screw member (coupling tool) 52 is screwed into the beam 20 through the screw insertion hole 51c, the joint member 51 can be attached to the side surface 20c of the beam 20 without the convex portion 20e getting in the way. Further, if the screw member 53 is screwed into the reinforcing member 50 through the second flat plate portion 51b of the joint member 51, the reinforcing member 50 can be reliably attached to the upper surface 20a of the beam 20. Therefore, by attaching the base material 60 to the lower surface 50a of the reinforcing member 50 and supporting the eaves material 40 by the base material 60, it becomes possible to cover and hide the folded plate 30 with the eaves material 40, and the appearance quality of the carport can be improved by renovation. Incidentally, the above-described joint member 51 can be similarly applied to the beam 20 without the convex portion 20e, which is also advantageous in terms of common use of parts. Further, the joint member 51 can be applied not only to the renovation of the carport but also, of course, to the case of newly constructing a carport.

[0018] Note that the joining member 51 is not limited to one in which the first flat plate portion 51a and the second flat plate portion 51b are integrally formed. For example, like the joining member 151 of the modified example shown in FIG. 8, after the first flat plate portion 151a and the second flat plate portion 151b are separately formed, it is also possible to connect the first flat plate portion 151a and the second flat plate portion 151b to form it. That is, in this modified example, a first member 151A having a first flat plate portion 151a formed in a flat plate shape and a second member 151B in which the second flat plate portion 151b and the connection plate portion 151d are integrally formed are separately formed from each other, and the first member 151A is connected to the outer surface 151e of the connection plate portion 151d to constitute the joining member 151. As is clear from the figure, the connection plate portion 151d is formed to be wider than the first member 151A. The first member 151A is connected so as to be offset toward the lower end side of the connection plate portion 151d. A gap larger than the protruding dimension of the convex portion 20e provided on the beam 20 is secured between the outer surface 151e of the connection plate portion 151d facing the side surface 20c of the beam 20 and the first contact surface 151f of the first flat plate portion 151a abutting on the side surface 20c of the beam 20.

[0019] Even when the joining member 151 of this modified example is applied, it is possible to abut the first flat plate portion 151a against the portion below the convex portion 20e on the side surface 20c of the beam 20 without a gap, and it is possible to securely attach the reinforcing member 50 to the upper surface 20a of the beam 20 without the convex portion 20e getting in the way. The joining member 151 of the modified example can be similarly applied to a beam 20 provided without the convex portion 20e, and the sharing of parts can be achieved. Further, the joining member 151 can be applied not only to the renovation of the carport but also, of course, when newly constructing a carport.

[0020] In addition, in the above-described embodiment, the roof structure 1 applied to the carport is illustrated, but it can also be applied to other roof structures. In this case, it is not necessarily required that the number of beams is two, and there may be three or more beams.

[0021] Furthermore, although the above-described embodiment illustrates a connecting plate portion 51d of the joining member 51 that is bent and extends upward, other shapes are also acceptable as long as they connect the first flat plate portion 51a and the second flat plate portion 51b while being separated from the side surface 20c of the beam 20. For example, the connecting plate portion may be provided so as to be inclined and extend upward from the upper edge of the first flat plate portion 51a, gradually separating from the side surface 20c of the beam 20.

[0022] As described above, the roof structure according to the present invention is a roof structure in which a reinforcing member is attached to the upper surface of a beam via a connecting member, wherein the connecting member has a first flat plate portion that abuts against the side surface of the beam and a second flat plate portion that abuts against the lower surface of the reinforcing member, and also has a connecting plate portion that connects the first flat plate portion and the second flat plate portion while being separated from the side surface of the beam. According to this invention, even if there is a protrusion at the corner of an already installed beam, the connecting plate allows the first flat plate to abut against the side of the beam without contacting the protrusion, and it is also possible to reliably attach a reinforcing material to the upper surface of the beam via the connecting member during renovations.

[0023] Furthermore, the present invention is characterized in that, in the roof structure described above, the first flat plate portion is provided with a plurality of connector insertion holes located at different positions from each other, and is attached to the beam by attaching a connector to the beam through a selected connector insertion hole. According to this invention, even when there are irregularities other than protrusions on the side surface of the beam, it becomes possible to attach the connector while avoiding these irregularities.

[0024] Furthermore, the present invention is characterized in that, in the roof structure described above, the reinforcing member is arranged in a manner that it gradually slopes downward from one end to the other, and the connecting member is provided between the lower surface of the reinforcing member located on the higher side and the side surface of the beam. According to this invention, since the angle between the beam and the reinforcing material exceeds 90°, the process of attaching the connector can be made easier.

[0025] Furthermore, the present invention is characterized in that, in the roof structure described above, the joining member is integrally formed with the first flat plate portion, the second flat plate portion, and the connecting plate portion. According to this invention, the manufacturing process of the joining members can be simplified, and their handling can be improved.

[0026] Furthermore, the present invention is characterized in that, in the roof structure described above, the joining member comprises a first member having the first flat plate portion and a second member in which the second flat plate portion and the connecting plate portion are integrally molded, and the first flat plate portion is connected to the connecting plate portion of the second member. According to this invention, it is possible to construct a joint member with a complex shape by connecting a first member and a second member with simple shapes.

[0027] Furthermore, the present invention is characterized in that, in the roof structure described above, the soffit material is supported by the reinforcing material via a base material. According to this invention, the soffit material can be supported on the beam via reinforcing materials and base materials. [Explanation of symbols]
