(Embodiment 1)
FIG. 1 shows an outdoor structure to which a support structure for columns according to the first embodiment of the present invention is applied. The outdoor structure illustrated here is a carport provided in a parking space, and includes a support column 1 and a roof 2. In the first embodiment, as shown in FIG. 1A, a cantilever type carport having two columns 1 provided only on one side edge of the roof 2 when viewed from the front is illustrated. ing. The support column 1 is an extruded shape member formed of an aluminum alloy, and is formed in a hollow shape having a rectangular cross section as shown in FIGS. 2 to 4. Each support column 1 is supported by an individual foundation 10 provided on the ground G, and is erected in a state of being substantially perpendicular to the ground surface E.

The foundation 10 has a rectangular parallelepiped shape formed by placing concrete. In the example shown in FIG. 1, a foundation 10 having a vertical and horizontal dimension of about 6 times in the long side direction and about 10 times in the short side direction is applied to the support column 1. A support member 11 is provided on each foundation 10. The support member 11 is configured to include a stiffening portion 11A and a support base portion 11B. The stiffening portion 11A and the support base portion 11B are each formed of an iron material. The stiffening portion 11A has a hollow shape with a rectangular cross section, and is configured so that the dimension L along the length is substantially the same as the height h of the foundation 10. The support base portion 11B has a hollow shape having a substantially square cross section, and is configured to have external dimensions that can be inserted into the hollow portion of the stiffening portion 11A.

More specifically, in the first embodiment, as shown in FIG. 2A, the opening width b along the short side of the stiffening portion 11A with respect to the support base portion 11B having the dimension a on one side. Is the same as the dimension a of one side of the support base 11B, and the opening length c along the length of the stiffening portion 11A is configured to be larger than the dimension a of one side of the support base 11B. As is clear from the figure, a step portion 11a is provided at the upper end portion of the stiffening portion 11A. The step portion 11a is configured to be parallel to the upper end surface at a position one step lower than the upper end surface of the stiffening portion 11A. In the first embodiment, the stepped portion 11a is formed by cutting off one end of the longitudinal portion of the stiffening portion 11A. The dimension d from the upper end surface of the stiffening portion 11A to the step portion 11a is set to be equal to or greater than the sum of the distance corresponding to the so-called cover thickness and the plate thickness t1 of the upper closing plate 13 described later. .. For the dimension f along the length of the step portion 11a, the dimension a of one side of the support base portion 11B is subtracted from the opening length c along the length of the stiffening portion 11A, and the plate thickness t2 of the stiffening portion 11A is added. The distance (= c-a + t2) is set.

As shown in FIG. 2B, the support base portion 11B and the stiffening portion 11A having the above-described configuration are joined to each other in a state where the lower end portion of the support base portion 11B is inserted into the hollow portion of the stiffening portion 11A (for example,). By welding), they are integrated into the support member 11. At this time, the support base portion 11B is biased toward the other end of the length with respect to the stiffening portion 11A, and the support is supported in a state where the three outer surfaces of the support base portion 11B are in contact with the inner side surface of the stiffening portion 11A, respectively. The base portion 11B and the stiffening portion 11A are joined together. The upper closing plate 13 is joined to close the opening formed in the stepped portion 11a of the stiffening portion 11A. As described above, the dimension d from the upper end surface of the stiffening portion 11A to the step portion 11a is set to be equal to or more than the total value of the cover thickness and the plate thickness t1 of the upper closing plate 13. Therefore, the distance from the upper surface of the upper closing plate 13 to the upper end surface of the stiffening portion 11A is separated by a dimension g equal to or larger than the cover thickness.

The attachment 14 is attached to the upper end of the support base 11B joined to the stiffening portion 11A. The attachment 14 is formed of an iron material and, like the stiffening portion 11A, has a hollow shape with a rectangular cross section. The outer shape of the attachment 14 is configured to have dimensions that allow it to fit into the hollow portion of the support column 1. In this attachment 14, the lower end surface abuts on the upper end surface of the stiffening portion 11A and projects to the side opposite to the stiffening portion 11A with respect to the support base portion 11B, and the three outer surfaces of the support base portion 11B are on the inner side surface, respectively. It is joined to the support base 11B in a state of contact. At this time, it is preferable to set each dimension so that the protruding dimension k of the attachment 14 from the stiffening portion 11A is equal to or larger than the above-mentioned cover thickness. The lower closing plate 15 is joined to close the opening formed at the lower end of the attachment 14. The attachment 14 may be joined not only with the support base portion 11B but also with the stiffening portion 11A.

In the support member 11 to which the attachment 14 is joined to the upper end portion as described above, the stiffening portion 11A is embedded inside the foundation 10 and the attachment 14 is exposed to the outside from the upper end surface 10b of the foundation 10. It is provided on the foundation 10. At this time, the distance between the outer surface 11b on the short side to which the support base 11B is joined in the stiffening portion 11A and one side surface 10a (the surface located on one edge) of the foundation 10 corresponds to the cover thickness. The distance between one side surface 10a of the foundation 10 and the outer surface 14a of the attachment 14 is set to be separated by a dimension n corresponding to the plate thickness t3 of the support column 1. Regarding the short side direction of the support member 11, the support member 11 is arranged so that the center of the support base portion 11B coincides with the center of the foundation 10.

With respect to the foundation 10 configured as described above, if the carport support column 1 is fitted to the attachment 14 protruding from the upper end surface 10b of the foundation 10, as shown in FIG. 4, one of the foundations 10 is attached. The side surface 10a and the side surface 1a of the support column 1 are located on the same plane. As a result, as shown in FIG. 1, if the foundation 10 is provided on the ground G so that one side surface 10a matches the adjacent land boundary line, the side surface 1a of the support 1 is also arranged at a position that matches the adjacent land boundary line. Will be done. Therefore, if a screw is screwed into the attachment 14 from the screw insertion hole of the support column 1 (not shown), the support column 1 is maintained in an upright state from the foundation 10 without creating a dead space between the support and the adjacent land boundary line. It becomes possible.

Moreover, inside the foundation 10, the distance from one side surface 10a to the outer surface 11b of the nearest stiffening portion 11A is separated by an interval m equal to or greater than the cover thickness. Further, the space between the upper end surface 10b of the foundation 10 and the upper surface of the upper closing plate 13 is also separated by a distance p equal to or larger than the cover thickness. Therefore, even when the foundation 10 is buried in the ground G, there is no possibility that the stiffening portion 11A, the upper closing plate 13 and the support base portion 11B are corroded by the influence of water, air, acid, salt and the like. ..

Further, according to the above-mentioned support structure, the support member 11 is made to support the support member 11 outside the foundation 10, and the support column 1 is not provided inside the foundation 10. Therefore, when the carport is replaced. There are also advantages such as facilitation of work.

In the first embodiment described above, since the openings of the stiffening portion 11A and the attachment 14 are covered by the upper closing plate 13 and the lower closing plate 15, the inside of the stiffening portion 11A and the inside of the attachment 14 There is no risk of concrete being filled. Further, when the upper closing plate 13 and the lower closing plate 15 are provided, it is possible to improve the strength of the edges of the stiffening portion 11A and the attachment 14. However, it is not always necessary to provide the upper closing plate 13 and the lower closing plate 15, and the support member 11 may be provided on the foundation 10 with the upper end of the stiffening portion 11A and the lower end of the attachment 14 open.

Further, in the above-described first embodiment, the support member 11 is provided as it is inside the foundation 10, but as shown in the modified example 1 shown in FIG. 5, for example, with respect to the stiffening portion 11A of the support member 11. The reinforcing member 16 may be provided so that both end portions project from the outer surface 11c on both sides. In particular, in the case of the cantilever type carport shown in FIG. 1, it is preferable to provide the reinforcing member 16 so as to be orthogonal to the extending direction of the beam 3 provided at the upper end of the support column 1, and further, each of the reinforcing members 16 is provided. It is preferable to provide a plurality of reinforcing members 16 with respect to the stiffening portion 11A along the same direction. In the illustrated example, a reinforcing member 16 having edge portions 16b bent in the same direction is applied to both side edges of the flat plate-shaped base portion 16a.

According to the support structure of the first modification, the fixing strength of the support member 11 to the foundation 10 is improved via the reinforcing member 16, so that the support strength of the support column 1 to the foundation 10 is also further improved. Therefore, for example, even if the roof 2 is blown up by a strong wind and a load is applied to the roof 2, there is no possibility of causing a problem such as the support column 1 tilting with respect to the foundation 10.

Further, in the above-described first embodiment, the support member 11 having the stiffening portion 11A and the support base portion 11B is applied, but the present invention is not limited to this, and the modified example 2 shown in FIG. As described above, it is also possible to configure only the member corresponding to the support base portion 11B to be directly provided on the foundation 10 as the support member 11. In the case of this modification 2, the one side surface 10a of the foundation 10 and the outer surface 11d of the support base portion (support member) 11B may be separated by a distance m equal to or larger than the cover thickness.

Further, in the above-described first embodiment, since the support member 11 supports the support column 1 via the attachment 14, it is possible to improve the support strength of the support column 1 with respect to the support member 11. However, the present invention is not limited to this, and it is also possible to directly join the support column 1 to the upper end portion of the support base portion (support member) 11B as in the modified example 3 shown in FIG. Also in the case of this modification 3, it is sufficient that one side surface 10a of the foundation 10 and the outer surface 11d of the support base portion (support member) 11B are separated by a distance m equal to or larger than the cover thickness. In the modified example 3, a support member 11 having a stiffening portion 11A may be applied. Further, when the support base portion 11B is directly provided on the foundation 10 and the support column 1 is directly joined to the support base portion 11B as in the modification example 3, the modification example 4 shown in FIG. 8 and the modification example 5 shown in FIG. 9 are formed. It is preferable to configure it as follows.

The base portion (support member) 11B is provided. As is clear from the figure, an insertion groove 1b is formed at a portion corresponding to the protruding piece 17 at the lower end portion of the support column 1. According to the support structure of the modified example 4, since the contact area with the foundation 10 is increased by the protruding piece 17, it is possible to improve the fixing strength of the support base portion (support member) 11B with respect to the foundation 10. The protruding piece 17 is preferably provided on the outer surface 11e which is opposite to the outer surface 11d. Further, the number of the protruding pieces 17 is not limited to one, and may be a plurality.

On the other hand, in the modified example 5 shown in FIG. 9, a part of the support column 1 is arranged inside the foundation 10. The outer portion 1A of the support column 1 arranged outside the foundation 10 has the same dimensions as that of the first embodiment, and is connected to the support base (support member) 11B by screwing a screw (not shown). There is. On the other hand, with respect to the inner portion 1B arranged inside the foundation 10 in the support column 1, one of the foundations 10 is provided so that the minimum distance q between the inner portion 1B and the one side surface 10a of the foundation 10 is equal to or larger than the cover thickness. The portion close to the side surface 10a is cut off. The inner portion 1B of the support column 1 may also be connected to the support base portion (support member) 11B by a screw.

According to the support structure of the modified example 5, since the support column 1 has a portion directly joined to the foundation 10, the support strength of the support column 1 can be improved, and for example, twisting of the support column 1 near the ground surface E can be prevented. There are advantages such as being able to do it. Moreover, inside the foundation 10, the distance from one side surface 10a to the outer surface 11d of the nearest support base (support member) 11B or the inner portion 1B of the support column 1 is separated by an interval m equal to or greater than the cover thickness. .. Therefore, even when the foundation 10 is buried in the ground G, the inner portion 1B of the support column 1 and the support base (support member) 11B may be corroded by the influence of water, air, acid, salt, or the like. No.
