Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above conventional structure, since the reinforcing member is provided outside the curved portion, for example, there is a risk that the appearance deteriorates or the dimensions and layout are restricted. Therefore, a structure for reinforcing the inside of the curved portion with a reinforcing member can be considered. In this case, for example, for a linear structural member having no curved portion, a method of inserting and reinforcing the reinforcing member from one end side of the hollow structural member to the inside is generally used.

[0005] However, it has not been possible to insert a curved reinforcing member along the curved portion from one end side of the structural member into a structural member having a curved portion that is already curved. Also, for example, a large load is required to bend the structural member after inserting the reinforcing member in advance, and there are other problems.

[0006] The present invention has been made in view of the above problems, and its object is to provide a highly versatile structure in which a reinforcing member can be added later to the inside of the curved portion. Structure ​

Means for Solving the Problem

[0007] In order to solve the above-described problems and achieve the object, the structure according to the present invention has a curved portion, a hollow structural member having at least one open end, and a reinforcing member inserted from the open end of the structural member and disposed in the hollow portion of the curved portion. The reinforcing member includes a plurality of divided bodies arranged side by side along the extending direction of the curved portion. The plurality of divided bodies are shaped members having two reinforcing walls facing the inner peripheral wall and the outer peripheral wall constituting the curved portion, and a vertical wall connecting between these two reinforcing walls, and are configured such that cross-sections orthogonal to the longitudinal direction of the hollow portion are the same as each other. The inner peripheral wall The reinforcing wall facing the is connected by a flexible connecting member, The connecting member is interposed between the reinforcing wall and the inner peripheral wall, and the outer peripheral wall The reinforcing wall facing the is joined, which is characterized in that.

Effect of the Invention

[0009] According to the present invention, for example, by dividing the reinforcing member into a plurality of divided bodies, the reinforcing member can be inserted inside the curved portion, and thus, a highly versatile structure and a method for manufacturing the structure that can add a reinforcing member inside the curved portion later even to a structural member having a curved portion in advance can be provided.

Best Mode for Carrying Out the Invention

[0011] Exemplary embodiments of the present invention will be disclosed below. The configurations of the embodiments shown below, as well as the actions and effects brought about by the configurations, are examples. The present invention can also be realized by configurations other than those disclosed in the following embodiments. Further, according to the present invention, it is possible to obtain at least one of various effects (including derivative effects) obtained by the configuration.

[0012] [Embodiment] FIG. 1 is a perspective view of an outdoor structure 1 according to an embodiment. In the following description, for convenience, when the outdoor structure 1 is viewed from the front, the front side will be referred to as the front, the back side as the back, the upper side as the top, the lower side as the bottom, the left side as the left, and the right side as the right. The front-rear direction is along the depth direction of the outdoor structure 1, the up-down direction is along the height direction of the outdoor structure 1, and the left-right direction is along the width direction of the outdoor structure 1.

[0013] As shown in FIG. 1, the outdoor structure 1 is configured as, for example, a carport of a vehicle, and includes a plurality of frame members such as columns 2, beam members 3, a roof 4, purlins 5, etc. that constitute an outer shell, and a roof panel 6 supported by the frame members. The outdoor structure 1 is an example of a structure.

[0014] In this embodiment, the outdoor structure 1 is configured as a wide-type carport, but is not limited to this example, and may be, for example, a cantilever type, an M-gable type, a Y-gable type, a depth connection type, an opening connection type, etc.

[0015] The frame members such as columns 2, beam members 3, roof 4, purlins 5, etc. are, for example, extruded profiles formed of a metal such as an aluminum alloy, and are configured to have a substantially uniform cross-section along the entire length along their respective lengths.

[0016] Here, in the present embodiment, a reinforcing member 10 (see FIG. 2), which will be described later, is provided inside at least the beam member 3 among the plurality of frame members described above. The beam member 3 is an example of a structural member.

[0017] As shown in FIG. 1, the beam member 3 extends, for example, in the longitudinal left - right direction and spans between a pair of left and right support columns 2. The beam member 3 has, for example, a curved portion 3a, a right end portion 3b, and a left end portion 3c.

[0018] The curved portion 3a is located between the right end portion 3b and the left end portion 3c and is bent, for example, in a convex - upward state. Inside the beam member 3 including this curved portion 3a, a hollow portion 3d extending between the right end portion 3b and the left end portion 3c is provided. The hollow portion 3d is surrounded, for example, by an upper wall 3f1, a lower wall 3f2, and two side walls 3f3 that constitute the outer wall 3f of the beam member 3.

[0019] The right end portion 3b is provided with an open end portion 3d1 of the hollow portion 3d that opens to the right. Here, in the present embodiment, the reinforcing member 10 is configured to be insertable into the hollow portion 3d from this open end portion 3d1. The right end portion 3b is an example of one end portion.

[0020] Also, the left end portion 3c is provided with an open end portion 3d2 of the hollow portion 3d that opens to the left. Note that the open end portions 3d1 and 3d2 of the beam member 3 are blocked by the support columns 2 in the assembled state of the outdoor structure 1 (the state in FIG. 1), but are open in the state before assembly. In the present embodiment, at least in this state before assembly, for example, in order to solve the problem of insufficient strength due to wind pressure or snow accumulation, the reinforcing member 10 can be selectively added inside the curved portion 3a.

[0021] Next, the reinforcing member 10 will be described in more detail. FIG. 2 is a perspective view of the reinforcing member 10. As shown in FIG. 2, the reinforcing member 10 has, for example, a plurality of divided bodies 11, a connecting member 12, and a pair of end members 13. The size of the reinforcing member 10 is set to be slightly smaller than the size of the hollow portion 3d.

[0022] The plurality of divided bodies 11 are arranged along the extending direction of the beam member 3, that is, the left - right direction. In the present embodiment, for example, eight divided bodies 11 are provided in the reinforcing member 10. Note that the number of divided bodies 11 is not limited to this example and can be variously changed according to, for example, the length and curvature of the curved portion 3a.

[0023] The connecting member 12 extends, for example, along the left - right direction and is overlapped below the plurality of divided bodies 11 and the end members 13. The connecting member 12 is integrated with the reinforcing walls 11b of the plurality of divided bodies 11 and the reinforcing wall 13b of the end member 13 by, for example, a coupling tool 15 (see FIG. 6) such as a screw or a bolt - nut.

[0024] A pair of end members 13 are provided at both ends in the left - right direction of the plurality of divided bodies 11. The end member 13 constitutes a part of the plurality of divided bodies 11 of the reinforcing member 10 together with the divided body 11. The reinforcing member 10 is made of, for example, iron or the like.

[0025] In the present embodiment, the end members 13 are provided at both ends in the left - right direction of the plurality of divided bodies 11, but this is not limited to this example. For example, it may be provided at one side in the left - right direction. Specifically, the end member 13 may be provided at the end on the side to be pushed in by the operating tool 30 (see FIG. 6) when inserting the reinforcing member 10 described later into the hollow portion 3d, that is, the side facing the operating tool 30.

[0026] FIG. 3 is a perspective view of the divided body 11. As shown in FIG. 3, the divided body 11 is configured in a substantially U - shaped form that is open forward when viewed from the left - right direction, for example. The divided body 11 has two reinforcing walls 11a, 11b and a vertical wall 11c.

[0027] The two reinforcing walls 11a, 11b are provided parallel to each other with a space therebetween in the vertical direction. The reinforcing wall 11a faces the upper wall 3f1 (see FIG. 6) on the outer peripheral side that constitutes the curved portion 3a, and the reinforcing wall 11b faces the lower wall 3f2 on the inner peripheral side that constitutes the curved portion 3a.

[0028] In addition, the reinforcing wall 11b is provided with a plurality of through holes 11d through which the above-described coupler 15 penetrates in the vertical direction. The plurality of through holes 11d are arranged side by side at intervals in the left-right direction.

[0029] The vertical wall 11c extends in the vertical direction across between the rear end portions of the reinforcing wall 11a and the reinforcing wall 11b. The vertical wall 11c faces the rear side wall 3f3 (see FIG. 6) that constitutes the curved portion 3a. The vertical wall 11c and the reinforcing walls 11a and 11b reinforce the inner surface 3e side of the curved portion 3a.

[0030] In this embodiment, the vertical wall 11c is provided only on one side in the front-rear direction of the divided body 11, but is not limited to this example. For example, it may be provided on both sides in the front-rear direction, or may be provided at a central position instead of at the end position in the front-rear direction.

[0031] FIG. 4 is a perspective view of the connecting member 12. As shown in FIG. 4, the connecting member 12 has, for example, a belt-shaped lower plate 12a. The lower plate 12a is interposed between the lower wall 3f2 on the inner peripheral side that constitutes the curved portion 3a, the reinforcing wall 11b of the divided body 11, and the reinforcing wall 13b of the end member 13.

[0032] The lower plate 12a is provided with a plurality of through holes 12b through which the coupler 15 penetrates in the vertical direction. The plurality of through holes 12b are provided corresponding to the through holes 11d of the divided body 11 and the through holes 13d of the end member 13.

[0033] In addition, the lower plate 12a has flexibility. That is, the lower plate 12a is configured to be deformable (curved) into a curved shape along the lower wall 3f2 (see FIG. 6) of the curved portion 3a.

[0034] In this embodiment, by individually connecting each of the divided bodies 11 to such a lower plate 12a with the coupler 15, the plurality of divided bodies 11 are connected to be relatively movable with respect to each other. The lower plate 12a is also referred to as a base, a connecting band, or the like.

[0035] Note that the connecting member 12 is not limited to this example, and may be constituted by, for example, a wire or the like. In this case, for example, the reinforcing member 10 can be inserted into the curved portion 3a by pulling the wire.

[0036] Also, the connecting member 12 does not necessarily need to connect all the divided bodies 11 and the end members 13. For example, a configuration may be adopted in which a plurality of lower plates 12a for connecting two (or more) adjacent divided bodies 11 are provided. Further, the reinforcing member 10 may be configured such that two adjacent divided bodies 11 are directly connected to be relatively movable with respect to each other without passing through the lower plate 12a, for example.

[0037] Furthermore, in the present embodiment, the lower plate 12a is connected below the divided body 11 and the end member 13, but is not limited to this example. For example, when the curved portion 3a of the beam member 3 is curved with a downward convex shape, the lower plate 12a is configured to be connected above the divided body 11 and the end member 13.

[0038] FIG. 5 is a perspective view of the end member 13. As shown in FIG. 5, the end member 13 is configured in a substantially U shape that is open toward the divided body 11 when viewed from the front-rear direction, for example. The end member 13 has two reinforcing walls 13a, 13b and an operation wall 13c.

[0039] The two reinforcing walls 13a, 13b are provided parallel to each other with a space therebetween in the vertical direction. The reinforcing wall 13a faces the upper wall 3f1 (see FIG. 6) on the outer peripheral side that constitutes the curved portion 3a, and the reinforcing wall 13b faces the lower wall 3f2 on the inner peripheral side that constitutes the curved portion 3a.

[0040] In addition, a plurality of through holes 13d through which the above-described coupler 15 penetrates in the vertical direction are provided in the reinforcing wall 13b. In the present embodiment, through holes 13d for the coupler 15 are also provided in the reinforcing wall 13a, and the configuration is such that it can be used even in a posture inverted up and down.

[0041] The operation wall 13c extends vertically between the reinforcing wall 13a and the reinforcing wall 13b. The operation wall 13c is a wall that constitutes the left and right end faces of the reinforcing member 10, and functions as a wall facing an operating tool 30 (see FIG. 6) that pushes the reinforcing member 10 toward the left end portion 3c side when inserting the reinforcing member 10 inside the curved portion 3a. The operating tool 30 is, for example, a pipe or the like.

[0042] FIGS. 6(a) to 6(c) are cross-sectional views for explaining a manufacturing method of the outdoor structure 1. FIG. 6(b) is a view showing a state later than that in FIG. 6(a), and FIG. 6(c) is a view showing a state later than that in FIG. 6(b).

[0043] As shown in FIGS. 6(a) to 6(c), a protrusion 20 is provided to the left of the reinforcing member 10. The protrusion 20 is provided, for example, in a state of protruding from the lower wall 3f2 of the curved portion 3a into the hollow portion 3d.

[0044] That is, at least a part of the protrusion 20 overlaps along the extending direction of the reinforcing member 10 and the curved portion 3a. The protrusion 20 is constituted by a coupling tool such as a screw, for example. The protrusion 20 is an example of a positioning portion.

[0045] In the present embodiment, the protrusion 20 is provided in a state of protruding from the lower wall 3f2 of the curved portion 3a into the hollow portion 3d, but is not limited to this example. For example, the protrusion 20 may be provided in a state of protruding from the upper wall 3f1 or the side wall 3f3 into the hollow portion 3d.

[0046] Further, the reinforcing member 10 has, for example, screws 16 that couple a plurality of divided bodies 11 and the upper wall 3f1 on the outer peripheral side that constitutes the curved portion 3a. In the present embodiment, for example, all the divided bodies 11, the end member 13, and the upper wall 3f1 of the curved portion 3a are coupled by a plurality of screws 16.

[0047] The screw 16 is an example of a coupling portion. The coupling portion is not limited to this example, and may be, for example, an adhesive or a welded portion.

[0048] Next, with reference to FIGS. 6(a) to 6(c), an example of a manufacturing method of the outdoor structure 1 will be described. First, as shown in FIG. 6(a), a curved portion 3a is formed in advance in the hollow beam member 3 (step S1). Next, a reinforcing member 10 in which a plurality of divided bodies 11, a connecting member 12, and an end member 13 are integrated is inserted from one open end portion 3d1 of the beam member 3 (step S2).

[0049] Next, as shown in FIG. 6(b), the reinforcing member 10 is pushed into the curved portion 3a side by the operating tool 30 (step S3). At this time, as shown in FIG. 6(b), a part of the reinforcing member 10 that has entered the curved portion 3a is deformed so that the gap between the plurality of divided bodies 11 gradually widens as it goes upward.

[0050] Next, as shown in FIG. 6(c), the reinforcing member 10 is pushed by the operating tool 30 to a position where it abuts on a protrusion 20 provided in the curved portion 3a (step S4). At this time, as shown in FIG. 6(c), the connecting member 12 is deformed (curved) along the lower wall 3f2 of the curved portion 3a, so that the gap between the plurality of divided bodies 11 widens as described above, and thus the reinforcing members 10 can be arranged side by side in a curved shape along the curved portion 3a.

[0051] Then, in a state where the reinforcing member 10 and the protrusion 20 are positioned, the plurality of divided bodies 11 and the upper wall 3f1 of the curved portion 3a are joined by screws 16 (step S5). With such a configuration, the beam member 3 of the outdoor structure 1 can be manufactured (reinforced).

[0052] As described above, in the present embodiment, the outdoor structure 1 (structure) includes a hollow beam member 3 (structural member) having a curved portion 3a and at least the right end portion 3b (one end portion) opened, and a reinforcing member 10 disposed in the hollow portion 3d of the curved portion 3a. The reinforcing member 10 is characterized in that it is configured by arranging a plurality of divided bodies 11 side by side along the extending direction of the curved portion 3a.

[0053] According to such a configuration, for example, by dividing the reinforcing member 10 into a plurality of divided bodies 11, the reinforcing member 10 can be inserted from the right end portion 3b into the inside of the curved portion 3a. As a result, it is possible to provide a highly versatile outdoor structure 1 in which the reinforcing member 10 can be additionally provided inside the curved portion 3a even for a beam member 3 having a curved portion 3a in advance.

[0054] Further, in the present embodiment, the divided body 11 is characterized by including two reinforcing walls 11a and 11b facing the inner peripheral side lower wall 3f2 and the outer peripheral side upper wall 3f1 constituting the curved portion 3a, and a vertical wall 11c connecting between these two reinforcing walls 11a and 11b.

[0055] According to such a configuration, for example, the rigidity and strength of the reinforcing member 10 and thus the curved portion 3a can be ensured by the two reinforcing walls 11a and 11b and the vertical wall 11c.

[0056] Further, in the present embodiment, an end member 13 as a divided body 11 located at the end of the reinforcing member 10 is characterized by being provided with an operation wall 13c constituting an end face.

[0057] According to such a configuration, for example, compared with a case where the U-shaped edge on the right end portion 3b side of the divided body 11 is pushed without providing the operation wall 13c on the reinforcing member 10, the reinforcing member 10 can be more easily moved to the curved portion 3a side by the operating tool 30. Also, for example, since the section modulus of the reinforcing member 10 is increased by the operation wall 13c, there may be a case where the rigidity and strength of the reinforcing member 10 and thus the curved portion 3a can be further enhanced.

[0058] Further, in the present embodiment, the plurality of divided bodies 11 are characterized by being connected by a connecting member 12 having flexibility.

[0059] According to such a configuration, for example, since the plurality of divided bodies 11 can be integrated by the connecting member 12, it is possible to increase the overall rigidity and strength of the reinforcing member 10, and to improve the insertability into the curved portion 3a, while making it easy for the reinforcing member 10 to follow the shape along the curved portion 3a.

[0060] Further, in the present embodiment, the structural member is the beam member 3 of the outdoor structure 1, and is characterized in that the curved portion 3a is arranged so as to protrude upward.

[0061] According to such a configuration, for example, it is possible to provide a beam member 3 in which the reinforcing member 10 can be added later inside the curved portion 3a by the reinforcing member 10 having a plurality of divided bodies 11.

[0062] Further, in the present embodiment, the manufacturing method of the outdoor structure 1 includes a hollow beam member 3 (structural member) having a curved portion 3a and at least the right end portion 3b (one end portion) opened, and a reinforcing member 10 disposed in the hollow portion 3d of the curved portion 3a. A manufacturing method of the outdoor structure 1, characterized in that after forming the curved portion 3a in the beam member 3 in advance, the reinforcing member 10 constituted by a plurality of divided bodies 11 is inserted from the open end portion 3d1 of the beam member 3 and disposed in the curved portion 3a.

[0063] According to such a configuration, for example, by dividing the reinforcing member 10 into a plurality of divided bodies 11, the reinforcing member 10 can be inserted inside the curved portion 3a, and thus, it is possible to provide a highly versatile manufacturing method of the outdoor structure 1 in which the reinforcing member 10 can be added later inside the curved portion 3a even to a beam member 3 having a curved portion 3a configured in advance.

[0064] The embodiments of the present invention have been illustrated above. However, the above embodiments are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, replacements, combinations, and changes can be made without departing from the gist of the invention. Also, the specifications of each component, shape, etc. (structure, type, direction, form, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be appropriately changed and implemented.
