This will be explained using figures. The cantilevered carport of this embodiment has a structure in which a roof 3 is supported at a slight inclination from a horizontal state by pillars 1 and beams 2 that are erected at predetermined intervals.

The pillar 1 is vertically erected as shown in the figure, and a beam 2 is connected to the tip of the pillar 1 and extends horizontally along the lower surface of the roof 3.

The roof 3 has a front frame 6, a rear frame 7, left and right side frames 8,
It has a structure in which a roof panel 11 is stretched over a roof frame formed by framing 8, intermediate horizontal beams 9, and intermediate vertical beams 10. The lower side of this roof 3 is a curved portion 3a that curves downward as shown in the figure.

The above-mentioned cantilevered carport holds the roof 3 in a cantilevered state by supporting the lower surface of the roof 3 with the beam 2 and supporting the lower side of the roof 3 having the curved part 3a with the pillars 1. This creates a space below where a car can be stored.

In the above cantilevered carport, pillar 1 and beam 2
Each uses a lightweight, rust-free aluminum hollow extrusion. Also, pillar 1 and beam 2
are continuously connected to each other by a casting connecting member 12. That is, the support column 1 and the beam 2 extend continuously as if they were a single member.

The casting connecting member 12 includes a curved portion 13 and insertion portions 15 and 16 extending from both ends of the curved portion 13, as shown in FIGS. 3 to 5. The curved portion 13 is the roof 3
It is curved with approximately the same curvature as the curved portion 3a, and has a length forming a circumferential angle slightly smaller than 90°. Further, this curved portion 13 is formed to have an I-shaped cross section so as to be lightweight and maintain a constant strength. Further, both ends of the curved portion 13 are connected to the insertion portion 1, respectively.
It is formed to match the dimensions of the ends of the support 1 and the beam 2 so that it abuts and continues with the ends of the support 1 and the beam 2 into which the 5 and 16 are inserted.

Insertion parts 15 and 16 extending from both ends of the curved part 13
extend straight from both ends, and are inserted into the upper end of the column 1 and the end of the beam 2 on the side of the curved part 3a.
The insertion portions 15 and 16 have a length such that bolts can be tightened at a plurality of positions spaced apart in the longitudinal direction of the column 1 and the beam 2, respectively.

In addition, the insertion parts 15 and 16 have fastening pieces 15 that fit snugly along the inner sides of the pillar 1 and the beam 2 on both sides.
It is formed to have an I-shaped cross section with holes 15a and 16a, and can be inserted into the support 1 and the beam 2 without wobbling by means of the fastening pieces 15a and 16a.

Bolt insertion holes 15b and 16b for passing the fixing bolt 20 are provided at two locations on the distal end side and on the side closer to the curved portion 13 of the insertion portions 15 and 16, respectively. These bolt insertion holes 15b, 16b are
As shown in the figure, each is provided through the fastening pieces 15a and 16a. In addition, the above-mentioned casting connecting member 12
At the locations corresponding to the bolt insertion holes 15b and 16b of the pillar 1 and the beam 2 into which the insertion parts 15 and 16 are inserted,
Holes communicating with the bolt insertion holes 15b and 16b are provided.

At least one bolt tightening portion of each of the insertion portions 15, 16 has the above-mentioned I-shaped cross section, and the cylindrical bolt insertion holes 15b, 16b through which the bolt 20 is inserted are integrally formed in the bolt tightening portion. It forms.

To connect the column 1 and the beam 2 using the casting connecting material 12, insert the insertion part 15 of the casting connecting material 12 into the upper end of the pillar 1, and insert the insertion part 16 into the end of the beam 2. . Then, as shown in Figures 3 and 5, the pillar 1
and bolt insertion holes 15b, 16b from the side of beam 2.
Pass the fixing bolt 20 through and tighten the bolt. As a result, the insertion portions 15 and 16 are bolted to the column 1 and the beam 2 at two locations spaced apart in the longitudinal direction. Here, as mentioned above, the casting connecting member 1
Since the curved portion 13 of the beam 2 has a length forming a circumferential angle slightly smaller than 90°, the beam 2 is supported by the support 1 in a state slightly inclined upward from the horizontal as shown in the figure.

Note that the material of the casting connecting member 12 may be aluminum, iron, or other metals. Furthermore, since the rear frame 7 of the roof 3 is screwed to the upper end of the support column 1 as shown in FIG. As shown in the figure, a groove 15c of a constant depth is provided so that a screw for fixing the rear frame 7 can be screwed into the support 1.

In the above embodiment, the curved portion 13 of the casting connecting member 12 has an I-shaped cross section, but it does not necessarily have to be I-shaped. For example, the curved portion 13 has the same cross-sectional shape as the end face shape of the support 1 and the beam 2, and the support 1
By adding the same pattern as the beam 2, it is possible to make the support 1 and the beam 2 appear to be seamlessly continuous.

Furthermore, although a case has been shown in which bolt insertion holes 15b and 16b are provided at two locations in the insertion portions 15 and 16 and bolts are tightened at two locations, bolts may be tightened at three or more locations. Further, in this embodiment, the bolt insertion holes 15b, 16b of the insertion portions 15, 16 are provided in the front-rear and up-down directions, but they may also be provided in the left-right direction.

[Effects of the invention] As explained above, in the present invention, the connecting part with the curved part of the column and beam made of hollow aluminum members is constructed with a cast connecting member, so the connecting part can be formed strongly and the shaking of the roof can be prevented. It can be prevented. Further, since the insertion portion of the cast connecting member is made to have an I-shaped cross section and is made long and bolted at two locations separated in the longitudinal direction, a strong and stable connection can be achieved. Furthermore, since at least one bolt tightening portion of each of the insertion portions is integrally formed as a cylindrical bolt insertion hole, the connection strength of the curved portions can be further increased. Furthermore, since the insertion section is I-shaped, materials can be saved, and since the connecting member is made of cast metal, the insertion section with an I-shaped cross section can be easily manufactured.
