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 enable 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 at least a portion of the roof body is formed from a roof material having a hollow portion, a reinforcing material placed in the hollow portion is fixed to the roof material, and the support column is attached to the reinforcing material. 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 an object of the present invention 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 3, 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, 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] Each of the multiple roof panels 55 is formed from an extruded aluminum material. Of the multiple roof panels 55, roof panel 55A, to which reinforcing member 11 (described later) is fixed, is formed from a hollow material 551 extending in the X-axis direction, and roof panels 55B other than roof panel 55A are formed from materials that extend in the X-axis direction and are open at the top. 4, the hollow member 551 of the roof panel 55A has a flat panel main body plate portion 552 that is long in the X-axis direction, a pair of rising portions 553 that are formed upward on both edges of the panel main body plate portion 552 in the X-axis direction, and a panel upper plate portion 554 that is continuous with the pair of rising portions 553, and is formed with a generally hollow rectangular cross section, and the panel main body plate portion 552, the pair of rising portions 553, and the panel upper plate portion 554 form a hollow portion 550 that extends along the longitudinal direction of the hollow member 551. In addition, a continuous piece portion 555 that is disposed between the pair of rising portions 553 is continuous with the panel main body plate portion 552 and the panel upper plate portion 554, and divides the hollow portion 550 into two hollow portions 550A and 550B. The panel main body piece 552 has an upright piece 553A extending upward from an edge thereof, and a connecting piece 553B bent outward from the upright piece 553A. Roof panel 55B is formed in a manner generally similar to roof panel 55A, except that it does not have the panel upper plate portion 554 and the continuous piece portion 555. Therefore, the same symbols as those used for each component of roof panel 55A will be used appropriately for roof panel 55B, and detailed explanations thereof will be omitted. Here, the connecting pieces 553B of roof panels 55 adjacent in the Y-axis direction overlap each other and are connected to each other by screws 9. The roof panels 55 also have engaging portions 556 (see FIG. 4) on both edges thereof, and the engaging portions 556 of adjacent roof panels 55 engage with each other. The above-mentioned multiple roof panels 55 have their rising portions 553 fastened together to the purlins 4 with screws 9. As a result, the roof body 5 is positioned lower than the beams 3 and the purlins 4, and the roof panels 55 arranged side by side in the Y-axis direction form a flat roof underside 560.

[0013] As shown in Figures 4 and 5, the support column mounting structure 10 is composed of a reinforcing member 11 fixed to a hollow extrusion 551 and a joint member 12 (engaging member) fixed to the lower part of the reinforcing member 11. The reinforcing member 11 is made of metal and extends along the longitudinal direction of the hollow extrusion 551. It has a bottom piece 111 fixed to a panel main body plate portion 552 of the hollow extrusion 551, a pair of side piece portions 112 rising upward from the bottom piece portion 111, and a pair of connecting piece portions 113 bent from the top of the pair of side piece portions 112 and connected to a panel upper plate portion 554 of the hollow extrusion 551. The connecting piece portions 113 are fastened together to the panel upper plate portion 554 and the purlin 4 by bolts 8. In this embodiment, the reinforcing member 11 is arranged in a hollow portion 550B formed in the hollow extrusion 551, extending from the beam 3 toward the front frame 52. The joint member 12 has a base plate portion 121, a shaft portion 122 that protrudes downward from the base plate portion 121, and a pair of protrusions 123 that protrude laterally from the periphery of the shaft portion 122. The base plate portion 121 is fastened together with the panel main body plate portion 552 and the bottom piece portion 111 of the reinforcing material 11 by screws 9A. Here, an engagement hole that releasably engages with the joint member 12 is provided at the upper end of the support column 6. The joint member 12 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. In this support column mounting structure 10, the reinforcing member 11 has its bottom piece 111 fixed to the panel main body plate portion 552 with a screw 9A, and the support column 6 is attached to the reinforcing member 11 via the joint member 12 by engaging the joint member 12 with the engaging hole. In this embodiment, the reinforcing member 11 has its connecting piece 113 also fixed to the purlin 4 with a bolt 8, and is indirectly attached to the beam 3 via the purlin 4, thereby further increasing the strength of the roof body 5. Note that in this embodiment, the fixing position where the bottom piece 111 of the reinforcing member 11 is fixed to the panel main body plate portion 552 with the screw 9A is closer to the front frame 52 in the X-axis direction than the fixing position where the connecting piece 113 of the reinforcing member 11 is fixed to the purlin 4 with the bolt 8.

[0014] 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 support column 6 is mounted to the reinforcing material 11 that is disposed in the hollow portion 550B and fixed to the roof body 5, so the mounting position of the support column 6 is not restricted by the position of the beam 3 or the position of the roof frame 51, and the support column 6 can be mounted at a position closer to the front frame 52 than the tip 3B of the beam 3 in the X-axis direction. Furthermore, because the reinforcing material 11 is disposed in the hollow portion 550B, it is not exposed to the outside, which reduces the exposure of the structure for mounting the support column 6 to the outside, improving the design and reducing the risk of water such as rainwater seeping into the portion where the reinforcing material 11 is disposed. In addition, workability is improved because the bottom piece portion 111 of the reinforcing member 11 is fixed to the panel body plate portion 552 of the hollow extrusion 551 with the screw 9A. For example, when a support column mounting bracket for attaching a support column 6 is inserted from below into the hollow portion 550B of the roof panel 55A and screwed to the beam 3, the support column mounting bracket must be held in a predetermined position deep within the roof panel 55A while being screwed to prevent it from falling, whereas the present invention does not require such holding and is therefore easier to work with.

[0015] [Variations] In the above embodiment, the joint member 12 having the shaft 122 and the like is screwed to the reinforcing material 11. However, instead of this, as in the modified example shown in FIGS. 6 and 7 , a plate-shaped engaging recess 15 as an engaging member having an engaging hole 13 formed therein may be fixed to the reinforcing material 11. In this case, the upper end of the support column 6 is provided with the joint member 12 having the shaft 122 and a pair of protrusions 123 described above that can engage with the engaging recess 15, and the panel main body plate portion 552 and the bottom piece portion 111 are formed with engaging holes of the same shape as the engaging hole 13 described above. The engaging hole 13 has a circular hole 131 into which the shaft 122 can be inserted and a pair of slits 132 that are continuous with the circular hole 131 and into which the pair of protrusions 123 are inserted, so that the joint member 12 as an engaging protrusion can be releasably engaged with the engaging recess 15 by rotating the support column 6 with the shaft 122 and the protrusions 123 inserted. In this case, the engaging member fixed to the reinforcing material 11 can be made smaller, and the design can be further improved. A flatter roof underside 560 can be configured. In the above embodiment, the reinforcing member 11 is indirectly fixed to the beam 3 via the purlin 4, but this is not limiting, and for example, if the carport 1 does not have a purlin, the reinforcing member 11 may be directly fixed to the beam 3. In this embodiment, since the reinforcing member 11 is long, it is possible to attach the support column 6 at a position beyond the tip 3B of the beam 3 in the case where the reinforcing member 11 is also fixed to the beam 3. Furthermore, although the reinforcing material 11 is fixed to the purlin 4, this is not limiting and it does not have to be fixed to the beam 3 or the purlin 4. In the embodiment, the pair of connecting piece portions 553B of the reinforcing material 11 are formed to be separated in the Y-axis direction, but this is not limiting, and the pair of connecting piece portions 553B may be formed continuously. In the above embodiment, hollow portion 550 is divided into hollow portions 550A and 550B, but this is not limiting and hollow portion 550 may not be divided. Furthermore, when hollow portion 550 is divided into hollow portions 550A and 550B, reinforcing material 11 may be disposed in hollow portion 550A instead of hollow portion 550B. 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.

[0016] [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 comprising a column, a beam supported by the column, and a roof body connected to the beam, characterized in that at least a portion of the roof body is formed of a roof material having a hollow portion, a reinforcing material placed in the hollow portion is fixed to the roof material, and the support column is attached to the reinforcing material. According to the support column mounting structure of the present invention, the support columns are attached to the reinforcing members that are placed in the hollow portions and fixed to the roof structure. Therefore, 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 positioned according to the site conditions. Furthermore, for example, when mounting the 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. Furthermore, since the reinforcing material is arranged in the hollow portion, exposure of the reinforcing material to the outside can be reduced, improving the design and preventing water such as rainwater from penetrating to the position where the reinforcing material is fixed to the roof body. 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, an engaging member to which the support column is engaged may be fastened together with the roof material to the lower part of the reinforcing material. With this configuration, only the engaging member with which the support column engages is placed at the bottom of the reinforcing material, and the reinforcing material itself is placed in the hollow section, so that the structure for attaching the support column is exposed to the outside to a minimum, while the support column can be easily attached and detached. (3) In the support column mounting structure of the present invention, the support column may be provided with an engaging protrusion that engages with the engaging member, and the engaging member may be configured as an engaging recess that engages with the engaging protrusion. With this configuration, the engaging member fixed to the lower part of the reinforcing material is configured as an engaging recess, so the engaging member can be made slimmer, thereby reducing the portion of the structure for attaching the support column that is exposed to the outside. (4) In the support column mounting structure of the present invention, the reinforcing member may be fixed directly or indirectly to the beam. With this configuration, the reinforcing material is fixed not only to the roofing material but also to the beams directly or indirectly, which can further increase the strength of the roof structure. One example of indirectly fixing the reinforcing material to the beams is when the reinforcing material is fixed to the purlins that are interposed between the beams and the roof structure. (5) In the support column mounting structure of the present invention, the reinforcing material is formed to extend along the longitudinal direction of the roof material, and the reinforcing material may be fixed to the roof material at its lower part and directly or indirectly fixed to the beam at its upper part. With this configuration, the reinforcing member along the longitudinal direction of the roofing material is fixed to the roofing material at its lower part and fixed directly or indirectly to the beam at its upper part, thereby further increasing the strength of the roof body. One example of indirectly fixing the reinforcing member to the beam is when the reinforcing member is fixed to the purlin interposed between the beam and the roof body. (6) In the support column mounting structure of the present invention, the reinforcing material may have a bottom piece portion fixed to the roof material, a side piece portion raised upward from the bottom piece portion, and a connecting piece portion bent from the upper part of the side piece portion and connected to the roof material. According to this configuration, since the reinforcing material has the above-mentioned connecting piece portion, the upper portion of the reinforcing material can be easily fixed to the roof material. (7) 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.
