Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, the above-mentioned reinforcing material often has a dimension along the longitudinal direction set larger than the mutual interval of the beams. Moreover, a situation may occur where the reinforcing material must be spanned between the beams in a state where a tight frame and a folded plate are provided on the upper surface of the beam. For example, when adding an eaves material to an already installed roof structure, it is essential to attach the reinforcing material in a state where the tight frame and the folded plate are provided on the upper surface of the beam. Here, if the end of the folded plate is in an open state, it is possible to carry out the work of spanning the reinforcing material over the upper surface of the beam by inserting it from the open end. However, in an already installed roof structure, the end of the folded plate is often covered with a nose concealing material, making it difficult to carry out the above-mentioned work.

[0005] Patent Document 1, mentioned above, also describes a method in which a reinforcing member is constructed from multiple reinforcing auxiliary members, which are then arranged on the upper surface of a beam and subsequently connected to one another. In other words, a reinforcing member of the desired length is obtained by connecting the ends of the reinforcing auxiliary members with connecting fittings. However, in the above method, the external dimensions of the reinforcing member change along the way due to the provision of connecting fittings. As a result, for example, if a base material is provided across a section with and without connecting fittings, there is a concern that the difference in external dimensions may lead to problems such as differences in the mounting positions between the two sections.

[0006] In view of the above circumstances, the present invention aims to provide a roof structure that can facilitate installation work without causing a situation in which the external dimensions of the reinforcing material are changed. [Means for solving the problem]

[0007] To achieve the above objective, the roof structure according to the present invention is a roof structure comprising two beams with tight frames on their upper surfaces and a reinforcing member provided spanning between the upper surfaces of these two beams, wherein the reinforcing member is composed of a first reinforcing member and a second reinforcing member, each having a hollow shape, connected in a series along their length, and a connecting member is provided in the hollow portion of the first reinforcing member, which is slidable along its length and whose protrusion dimension from the end of the first reinforcing member can be changed via an operating part provided on the outside of the first reinforcing member, and the first reinforcing member and the second reinforcing member are connected to each other via the connecting member. [Effects of the Invention]

[0008] According to the present invention, since a system equipped with a first reinforcing member and a second reinforcing member is applied, it is possible to simplify the installation work even when a tight frame or corrugated sheet is provided on the upper surface of the beam. Moreover, since the second reinforcing member is connected to the hollow portion of the first reinforcing member by a connecting member, the external dimensions of the reinforcing member do not change. Therefore, for example, even when a base material is provided on the lower surface of the reinforcing member to support the soffit material, it does not lead to situations such as differences in the installation position.

[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 4 show a carport, an outdoor structure to which an embodiment of the present invention's roof structure is applied. The carport illustrated here is, for example, rectangular in shape and installed in a flat parking space, and is equipped with a roof structure 1 on top of four columns 10. The columns 10 are formed from a metal such as an aluminum alloy and are, for example, constructed in a cylindrical shape with a square cross-section. In the illustrated example, two columns 10 are erected 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 and lower surfaces extending horizontally and their two sides extending vertically, and are configured to be at different heights from each other. Each of the four corners of the beams 20 is provided with a protrusion 20a. The protrusions 20a are provided so as to project laterally from both corners on the upper surface of the beams 20, and so as to project laterally and downward from both corners on the lower surface of the beams 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 section 30a, an inclined wall section 30b, and a lower wall section 30c arranged in sequence, 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 of each beam 20 via a tight frame 31. More specifically, the corrugated sheet 30 is supported on the upper surface of the beam 20 via the tight frame 31, with the bends between the upper wall section 30a and the inclined wall section 30b, and the bends between the lower wall section 30c and the inclined wall section 30b, respectively, perpendicular to the extending direction of the beam 20. The tight frame 31 is a narrow member arranged along the length of the beam 20. The tight frame 31 and the corrugated sheet 30 are connected to each other, for example, by inserting a screw member 31a 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 31a. As described above, the two beams 20 are configured to be of different heights. Therefore, the corrugated sheet 30, which is arranged across the two beams 20, is positioned at an incline so that it gradually decreases 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] Below the corrugated sheet 30, a soffit material 60 is installed via reinforcing members 40 and base material 50. The reinforcing members 40 are installed so as to span between the upper surfaces of 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 70. In the illustrated example, multiple reinforcing members 40 are installed between the beams 20. The length of the reinforcing members 40 is approximately equal to the length of the corrugated sheet 30 in the direction perpendicular to the beams 20. The base material 50 extends along the longitudinal direction of the beams 20 and is attached so as to span across the lower surfaces of the multiple reinforcing members 40. The length of the base material 50 is approximately equal to the length of the corrugated sheet 30 in the direction of extension of the beams 20. The soffit material 60 is constructed to form a plate shape and is attached to the lower surface of the base material 50. These soffit materials 60 are arranged side by side to cover the entire area below the corrugated sheet metal 30.

[0015] Here, in the roof structure 1 described above, the four circumferences of the folded plate 30 are covered by the nose concealing material 33. Therefore, it is an extremely difficult operation to provide the reinforcing material 40 between the beams 20 in this state. For this reason, in the above-mentioned carport, as shown in FIGS. 3 to 9, a series of reinforcing materials 40 are configured by connecting a plurality of reinforcing members 41 and 42 to each other. In the illustrated example, the reinforcing material 40 is configured to include a central reinforcing member (first reinforcing member) 41 disposed between the beams 20 and two end reinforcing members (second reinforcing members) 42 continuous with both ends of the central reinforcing member 41. The two end reinforcing members 42 each have a rectangular tubular cross section and are formed of a metal such as an aluminum alloy. The dimensions along the longitudinal direction of the two end reinforcing members 42 may be the same or different from each other as long as the total value of the dimensions along the longitudinal direction of the central reinforcing member 41 described later is the dimension of the required reinforcing material 40. The central reinforcing member 41 is provided with connecting members 43 at both ends of the member body 41a. The member body 41a has a rectangular tubular shape and is configured to have the same shape and the same dimensions as the end reinforcing member 42 in cross section. The dimension along the longitudinal direction of the member body 41a is configured to be shorter than the mutual interval of the beams 20. The connecting member 43 has a vertical wall portion 43a and two horizontal wall portions 43b extending in the same direction from the upper and lower ends of the vertical wall portion 43a, and is configured to have a dimension that can be fitted inside the tube of the member body 41a. Each connecting member 43 is disposed inside the tube from both ends of the member body 41a and can move along the longitudinal direction of the member body 41a. An operating screw member (operating portion) 44 is provided on the vertical wall portion 43a of the connecting member 43. The operating screw member 44 projects to the outside through a notch 41b provided along the longitudinal direction of the member body 41a, and the position of the connecting member 43 with respect to the member body 41a can be changed from the outside of the member body 41a by moving it inside the notch 41b.

[0016] In order to dispose the reinforcing member 40 configured as described above between the upper surfaces of the beams 20, as shown in FIG. 7, the end reinforcing members 42 are arranged on the upper surfaces of the beams 20 in advance. That is, the end reinforcing members 42 are inserted between the beams 20 and disposed on the upper surfaces of the beams 20 between the tight frame 31 and the beams 20. The dimension along the longitudinal direction of each end reinforcing member 42 is smaller than that of the reinforcing member 40. Therefore, even in the state where the tight frame 31 is attached to the upper surface of the beam 20, the above-described operation can be easily performed.

[0017] Next, as shown in FIG. 8 from this state, the central reinforcing member 41 is disposed between the end reinforcing members 42. At this time, the connecting member 43 is disposed in a state of being accommodated in the cylinder inside the member body 41a via the operating screw member 44, and the protruding amount from the end face of the member body 41a is set to zero. In other words, the dimension along the longitudinal direction of the central reinforcing member 41 is set to match the dimension along the longitudinal direction of the member body 41a. Therefore, in this state, the central reinforcing member 41 can be easily disposed between the two end reinforcing members 42.

[0018] Next, when the connecting member 43 is protruded from the end of the member body 41a via the respective operating screw members 44 from the above-described state, as shown in FIG. 9, the connecting member 43 enters the cylinder inside the end reinforcing member 42. Therefore, when the screw member S is screwed into the connecting member 43 through the lower surface of the end reinforcing member 42 and the screw member S is also screwed into the connecting member 43 through the lower surface of the member body 41a, the central reinforcing member 41 is connected between the end reinforcing members 42 via the connecting member 43, and a series of reinforcing members 40 having a desired length can be configured. After the screw member S is screwed into the connecting member 43, the operating screw member 44 may be removed.

[0019] In the reinforcing member 40 constructed as described above, the connecting member 43 is positioned inside the cylinder of the main body 41a of the central reinforcing member 41 and inside the cylinder of the end reinforcing member 42, and does not affect the external dimensions in any way. Therefore, even when the base material 50 is placed across the lower surfaces of multiple reinforcing members 40, there is no risk of problems such as differences in mounting positions occurring, and there is no concern that problems such as gaps occurring in the soffit material 60 supported by it will occur.

[0020] In the embodiment described above, a roof structure 1 applied to a carport is shown as an example, but it can also be applied to other roof structures 1. In this case, the number of beams 20 does not necessarily have to be two; there may be three or more beams, and the number of reinforcing members constituting the reinforcing member 40 may be four or more. The dimensions of the central reinforcing member 41 placed between the beams 20 are set to be smaller than the spacing between the beams 20, but even if it is set to be slightly longer than the spacing between the beams 20, it is still possible to insert and place them between the tight frames 31.

[0021] Furthermore, in the embodiment described above, the connecting member 43 is provided on the central reinforcing member 41, but it is also possible to provide the connecting member 43 on the end reinforcing member 42. That is, it is also possible to first provide the connecting member 43 on the end reinforcing member 42 which is placed on the upper surface of the beam 20, and then insert the connecting member 43 into the cylindrical part of the central reinforcing member 41 to connect the two.

[0022] Furthermore, in the above-described embodiment, the connecting member 43 is exemplified as having a vertical wall portion 43a and two horizontal wall portions 43b extending in the same direction from both the upper and lower ends of the vertical wall portion 43a, but the shape of the connecting member 43 is not limited to this. For example, a rectangular cylindrical shape that is slightly smaller than the reinforcing members 41 and 42 may be applied, as in the connecting member 143 of the modified example 1 shown in Figure 10, or a connecting member 243 of the modified example 2 shown in Figure 11, in which the horizontal wall portion 243b extends from one end of the vertical wall portion 243a may be applied. In all of these connecting members 43, 143, and 243, they are in contact with the upper horizontal wall portions 41a and 42a and the lower horizontal wall portions 41b and 42b inside the cylinder of the reinforcing members 41 and 42. Therefore, the situation in which the reinforcing member 40 bends vertically at the connecting portion of the reinforcing members 41 and 42 is prevented, which is advantageous in terms of strength.

[0023] As described above, the roof structure according to the present invention is a roof structure comprising two beams with tight frames on their upper surfaces and a reinforcing member provided spanning between the upper surfaces of these two beams, wherein the reinforcing member is composed of a first reinforcing member and a second reinforcing member, each having a hollow shape, connected in a series along their longitudinal direction, and a connecting member is provided in the hollow portion of the first reinforcing member, which is slidable along its longitudinal direction and whose protrusion dimension from the end of the first reinforcing member can be changed via an operating part provided on the outside of the first reinforcing member, and the first reinforcing member and the second reinforcing member are connected to each other via the connecting member. According to this invention, since a system equipped with a first reinforcing member and a second reinforcing member is applied, it is possible to simplify the installation work even when a tight frame or corrugated sheet is provided on the upper surface of the beam. Moreover, since the second reinforcing member is connected to the hollow part of the first reinforcing member by a connecting member, the external dimensions of the reinforcing member do not change. Therefore, for example, even when a base material is provided on the lower surface of the reinforcing member to support the soffit material, it does not lead to situations such as differences in the installation position.

[0024] Furthermore, the present invention is characterized in that, in the roof structure described above, the first reinforcing member is provided with a notch along its longitudinal direction, and the operating portion protrudes to the outside of the first reinforcing member through the notch. According to this invention, by changing the position of the operating part along the notch, it is possible to change the protrusion dimension from the end of the first reinforcing member of the connecting member.

[0025] Furthermore, the present invention is characterized in that, in the roof structure described above, a folded plate is provided on the upper surface of the beam via the tight frame, and a fascia board is provided at a position that is on the extension of the end of the folded plate. According to this invention, the edges of the corrugated sheet metal are covered by the fascia board, which is advantageous in terms of appearance quality.

[0026] 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 by the reinforcing material via the base material. [Explanation of symbols]
