Description

[Technical Field]

[0001] The present invention relates to a support column mounting structure for removably mounting a support column (auxiliary column) to a roof structure such as a carport, and to the roof structure. [Background technology]

[0002] Conventionally, there is known a roof structure comprising pillars, beams connected to the pillars, and a roof body connected to the beams (see Patent Document 1). This roof structure is provided with support column mounting brackets (mounting brackets) fixed to the beams. The support column mounting brackets are configured to be able to engage and disengage with the upper ends of the support columns (auxiliary columns). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-123652 Summary of the Invention [Problem to be solved by the invention]

[0004] In the roof structure described in Patent Document 1, the support column mounting brackets are fixed to the beams, so their positioning is restricted by the location of the beams. This makes it difficult to install the support column mounting brackets at a position beyond the tip of the beams (i.e., toward the front end of the roof structure). For example, extending the beams to the aforementioned location and installing the support column mounting brackets at that position would make it difficult to reduce costs. Furthermore, if the support column mounting brackets were installed on a frame (frame body) such as the front girder (front frame) of the roof body, the positioning of the support column mounting brackets would be restricted by the location of the frame. Thus, in the roof structure described in Patent Document 1, the freedom of selection of the location for installing the support column mounting brackets is restricted by the location of the beams and frame, which can make it difficult to install the support columns in a position that suits the site conditions.

[0005] An object of the present invention is to provide a support column mounting structure and a roof structure that increase the degree of freedom in selecting the mounting position of the support column. [Means for solving the problem]

[0006] The support column mounting structure of the present invention is a support column mounting structure configured to allow a support column to be mounted to a roof structure comprising a column material, a beam supported by the column material, and a roof body connected to the beam, characterized in that a mounting member is extended from the beam and the support column is mounted to the mounting member. The roof structure of the present invention is a roof structure comprising a pillar, a beam supported by the pillar, and a roof body connected to the beam, and is characterized in that the support column mounting structure of the present invention described above is configured. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a support column mounting structure and a roof structure that increase the degree of freedom in selecting the mounting position of the support column. [Brief explanation of the drawings]

[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 to 4, carport 1 as a roof structure according to this embodiment has pillars 2 erected on the ground, beams 3 with base ends 3A supported by pillars 2, and roof body 5 connected to beams 3 via purlins 4, and is provided with a support pillar mounting structure 10 for removably mounting support pillars 6 (auxiliary pillars) that reinforce carport 1. Support pillars 6 are attached to carport 1 to increase the strength of carport 1 in response to strong winds, snow accumulation, etc., and can be removed from carport 1 after use. In the following description, for convenience, the frontage direction of the carport 1 is referred to as the X-axis direction, the depth direction of the carport 1 as the Y-axis direction, and the up-down direction of the carport 1 as the Z-axis direction. The X, Y, and Z-axis directions are perpendicular to each other. Also, for convenience, the side of the front frame 52 described later is referred to as the front side, the side of the rear frame 53 described later is referred to as the rear side, and the side frame 54 described later is referred to as the side side.

[0010] The pillar material 2 is formed from an extruded aluminum material and comprises a pillar body 21 along the Z-axis direction and a pillar cover 22 attached along the pillar body 21, the interior of the pillar cover 22 forming a path for draining water such as rainwater guided from the gutter frame 7 (described later) to the ground. Two pillar materials 2 are provided at an interval in the Y-axis direction. The beam 3 is formed from an extruded aluminum material, and its base end 3A is connected to the upper end of the column body 21, extends in the X-axis direction, and is slightly inclined upward from the rear frame 53 side to the front frame 52 side, which will be described later. The tip 3B of the beam is located closer to the rear frame 53 than the roof body 5 in the X-axis direction. Two beams 3 are provided with a gap between them in the Y-axis direction. The main frame 4 is formed from an extruded aluminum material and extends along the Y-axis direction, and in this embodiment, two main frames 4 are attached to the underside of the beams 3 at an interval in the X-axis direction. The number of pillars 2, beams 3 and purlins 4 is set appropriately depending on the size of the carport 1, etc.

[0011] The roof body 5 is disposed below the beams 3, and includes a roof frame 51 and a plurality of roof panels 55 (roof materials) arranged side by side within the roof frame 51 and extending in the X-axis direction. The roof frame 51 comprises a front frame 52 and a rear frame 53 formed from extruded aluminum and extending in the Y-axis direction, and a pair of side frames 54 also formed from extruded aluminum and extending in the X-axis direction, connected to both ends of the front frame 52 and the rear frame 53. A gutter frame 7 is attached to the side frames 54 and extends in the Y-axis direction on the rear frame 53 side of the roof body 5. The pair of side frames 54 are inclined obliquely upward from the rear frame 53 side to the front frame 52 side, and the front frame 52 is positioned higher than the rear frame 53. Therefore, the roof panels 55 arranged side by side within the roof frame 51 are positioned such that their front ends on the front frame 52 side are positioned higher than their rear ends on the rear frame 53 side, and are inclined like the pair of side frames 54, thereby setting a roof slope for the roof body 5. The gutter frame 7 is disposed on the rear end side of the roof panel 55 to catch water running down the roof panel 55 and guide it into the column cover 22.

[0012] The multiple roof panels 55 are each formed from an extruded aluminum profile, and each of the roof panels 55 is formed from a profile that extends in the X-axis direction and is open at the top, and is arranged side by side in the Y-axis direction. The roof panel 55 has a panel main body plate portion 552 that is long and flat in the X-axis direction, and a pair of rising portions 553 that are formed by rising upward on both edges along the X-axis direction of the panel main body plate portion 552. The rising portions 553 of the multiple roof panels 55 are connected to each other with screws or the like, and the multiple roof panels 55 form a flat roof underside 560. The above-mentioned plurality of roof panels 55 have their rising portions 553 fixed to the purlins 4 by screws 9A. Therefore, the roof body 5 is disposed lower than the beams 3 and the purlins 4.

[0013] The support column mounting structure 10 is composed of a mounting member 11 that extends from the beam 3 and to which the upper end of the support column 6 engages, and a water-stopping member 12 that is arranged between the mounting member 11 and the roof body 5, and a sealer 13 (see Figure 5) is interposed between the water-stopping member 12 and the panel main body plate portion 552.

[0014] The mounting member 11 is made of metal and formed to extend in the X-axis direction, and has a substantially U-shaped cross section, including a fixed piece 111 along the Y-axis direction that is fixed to the beam 3 by a bolt 8, and a pair of side pieces 112 that hang down from both edges of the fixed piece 111 along the X-axis direction and along the Z-axis direction. At an end 11A of the mounting member 11 on the pillar 2 side, the fixed piece 111 is fixed to the tip 3B of the beam 3. At an end 11B of the mounting member 11 on the front frame 52 side, a joint member 113 (engagement member) that engages with the upper end of the support column 6 is configured on the fixed piece 111. 5 and 6, the joint member 113 has a shaft portion 122 that protrudes downward from the fixing piece portion 111, and a pair of protrusions 123 that protrude laterally from the periphery of the shaft portion 122. Here, an engagement hole (not shown) that releasably engages with the joint member 113 is provided at the upper end of the support column 6. The joint member 113 is configured as an engagement protrusion that protrudes downward, and the engagement hole is configured as an engagement recess into which the engagement protrusion is inserted and engaged.

[0015] The water-stopping member 12 is made of resin and has a cylindrical tube portion 125 that penetrates in the Z-axis direction and an annular flange portion 126 that extends outward from the lower end of the tube portion 125, and has vertical dimensions that allow it to be pressed against the fixing piece portion 111 of the mounting member 11 at the top and to be pressed against the roof body 5 at the bottom via a sealer 13. The upper part of the tubular part 125 is disposed between the pair of side piece parts 112 of the mounting member 11 and is disposed so as to cover the periphery of the joint member 113. Furthermore, the upper end part of the support pillar 6 is inserted into the inside of the tubular part 125, and the tubular part 125 is disposed so as to cover the periphery of the upper end part of the support pillar 6. The water blocking member 12 is not fixed to the mounting member 11 and the panel main body plate portion 552 by fasteners such as screws (non-fixed), but is sandwiched between the mounting member 11 and the panel main body plate portion 552.

[0016] In this embodiment, the sealer 13 is a dry sealing material and is formed in a ring shape along the underside of the aforementioned flange portion 126. Since the water-stopping member 12 has the above-mentioned vertical dimensions, the sealer 13 is in close contact with the flange portion 126 of the water-stopping member 12, which is pressed downward, and the panel main body plate portion 552 of the roof panel 55. In addition, a hole 552A (see FIG. 6) through which the support column 6 is inserted is formed in the panel body plate portion 552 of the roof panel 55 above which the waterproofing member 12 is arranged.

[0017] In this support column mounting structure 10, the support column 6 is inserted into the hole 552A of the roof panel 55 and the tubular portion 125 of the water-stopping member 12, and the engagement hole (not shown) at the upper end of this support column 6 engages with the joint member 113 configured on the mounting member 11 extended from the beam 3, thereby achieving an attached state in which the support column 6 is attached to the mounting member 11 at a position between the beam 3 and the front frame 52 and above the roof body 5. At this time, the water-stopping member 12 covers the periphery of the support column 6, and the sealer is in close contact with the flange portion 126 and the panel main body plate portion 552 as described above, so that water such as rainwater running down the upper surface of the roof panel 55 is prevented from flowing downward through the hole 552A.

[0018] The above carport 1 has sufficient strength under normal circumstances and can be used without attaching the support pillars 6, but in cases where strong winds or snow accumulation may occur and it is desired to reinforce the above strength, the support pillars 6 are temporarily attached via the support pillar mounting structure 10 described above. In the support column mounting structure 10 of this embodiment, the mounting position of the support column 6 is not restricted by the position of the beam 3 or the position of the frame body, such as the front frame 52, that forms the periphery of the roof structure 5. This increases the flexibility in selecting the mounting position of the support column 6, allowing the support column 6 to be mounted in a position that suits the site conditions. Furthermore, when mounting the support column 6 at a position beyond the tip 3B of the beam 3, it is not necessary to use a beam 3 that extends to that position. This allows the beam 3 to be constructed with the minimum dimensions necessary for strength, thereby reducing costs. Furthermore, because the upper end of the support column 6 is attached to the mounting member 11 above the roof structure 5, the mounting portion of the support column to the mounting member is not exposed below the roof structure 5. This prevents water, such as rainwater, flowing on the roof structure 5 from flowing downward through the hole 552A where the support column 6 passes through the roof structure. This eliminates the need for fasteners, such as screws, to secure the water-stopping member 12 to the mounting member 11 or the roof structure 5.

[0019] [Variations] In the above embodiment, the aforementioned joint member 113 is configured on the mounting member 11, but instead, as shown in Figures 7 and 8, for example, an engaging member 115 having an engaging hole 114 formed therein may be configured on the mounting member 11. In this case, a joint member 113B formed in the same manner as the joint member 113 is configured on the upper end of the support column 6. The engaging member 115 has a rectangular plate-shaped mounting piece portion 116 extending along the X and Y axes, and a pair of side pieces 117 raised upward from both edges of the mounting piece portion 116 along the X axis direction, and is fixed to the fixed piece portion 111 of the mounting member 11 by the pair of side pieces 117. The engaging hole 114 is formed in the mounting piece portion 116, and has a circular hole portion 118 into which the shaft portion 122 of the joint member 113B is inserted, and a pair of slits 119 that are continuous with the circular hole portion 118 and into which a pair of protrusions 123 are inserted, and when the support pillar 6 is rotated with the shaft portion 122 and the protrusions 123 inserted, the joint member 113B can be releasably engaged with the engaging member 115. In the above embodiment, the tubular portion 125 of the water-stopping member 12 is formed in a cylindrical shape, but is not limited to this, and may be formed in a rectangular tubular shape or the like as long as it is tubular. In the above embodiment, the sealer 13 is interposed between the waterproofing member 12 and the roof panel 55, but instead of this, a wet sealant may be applied. In the above embodiment, the beams 3 are indirectly connected to the roof body 5 via the purlins 4, but they may also be directly connected to the roof body 5. In the above embodiment, a carport 1 in which the beams 3 are arranged on top of the roof body 5 is described, but this is not limited to this, and the carport may also be in a form in which the beams 3 are arranged under the roof body 5. In the above embodiment, the carport 1 has been described as a roof structure, but the present invention is not limited to the carport 1 and may be any roof structure that constitutes a roof.

[0020] [Summary of the present invention] (1) The support column mounting structure of the present invention is a support column mounting structure configured to enable a support column to be mounted to a roof structure having a column material, a beam supported by the column material, and a roof body connected to the beam, characterized in that a mounting member is extended from the beam and the support column is mounted to the mounting member. According to the support column mounting structure of the present invention, the mounting members to which the support columns are attached are extended from the beams, so the mounting positions of the support columns are not restricted by the positions of the beams or the frame that forms the periphery of the roof structure, increasing the degree of freedom in selecting the mounting positions of the support columns. This allows the mounting positions of the support columns to be located in a position that suits the site conditions. Furthermore, when mounting support columns at a position beyond the tip of the beam, it is possible to eliminate the need for a beam that extends to that position. This allows the beam to be constructed with the minimum dimensions necessary for strength, thereby reducing costs. The beams are connected directly to the roof body, and also indirectly via purlins or the like. (2) In the support column mounting structure of the present invention, the roof body may be positioned below the beam, and the upper end of the support column may be inserted through the roof body and attached to the mounting member above the roof body. With this configuration, the upper end of the support pillar inserted through the roof body is attached to the mounting member above the roof body, so that the mounting portion of the support pillar to the mounting member is not exposed on the lower side of the roof body, thereby improving the design. (3) In the support column mounting structure of the present invention, a water-stopping member having a tubular portion may be arranged between the mounting member and the roof body, and the support column may be inserted into the tubular portion. With this configuration, the support pillar is inserted into the tubular portion of the water-stopping member described above on the roof body, and therefore the water-stopping member can prevent water such as rainwater flowing on the roof body from flowing downward from the portion where the support pillar is inserted into the roof body, thereby improving water-stopping properties. (4) In the support column mounting structure of the present invention, the water-stopping member may be pressed against the mounting member at an upper portion and in pressure contact with the roof body at a lower portion. With this configuration, there is no need to provide fasteners such as screws to secure the water-stopping member to the mounting member or roof body, and by pressing the water-stopping member against the roof body, the risk of water seeping in between the roof body and the water-stopping member is reduced, thereby further improving water-stopping performance and improving workability. (5) In the support column mounting structure of the present invention, a sealer may be interposed between the water-stopping member and the roof body. With this configuration, the sealer is pressed between the water-stopping member and the roof body, causing it to adhere closely to the water-stopping member and the roof body, thereby further improving water-stopping properties. (6) The roof structure of the present invention is a roof structure comprising a pillar, a beam supported by the pillar, and a roof body connected to the beam, and is characterized in that the support column mounting structure of the present invention described above is configured. According to the roof structure of the present invention, it is possible to configure a roof structure that can achieve the same effects as those of the support column mounting structure of the present invention described above.
