Additionally, there was a problem in that the through bolt could not be tightened too strongly and a strong connection could not be achieved. Furthermore, since the load applied to the hollow support and the hollow beam must be supported only by the thickness of each member, there is a drawback that the strength against the load cannot be obtained.

[Means for Solving the Problems] The present invention, which solves the above-mentioned conventional problems, provides a hollow support in which a hollow beam is inserted into an insertion hole or notch provided in a hollow support and fastened with a through bolt. and a hollow beam material, a reinforcing plate is fixed to the inner wall of the hollow column, a through hole is provided in the hollow column and the reinforcing plate, a reinforcing spacer is fixed to the inside of the hollow beam material, and a reinforcing plate is fixed to the inner wall of the hollow column. A through hole is provided in the beam material and the reinforcing spacer, a through bolt is passed through the hollow column, the reinforcing plate, the hollow beam material and the reinforcing spacer, and the reinforcement and the reinforcing spacer are sandwiched and fastened by the through bolt.

By fixing the reinforcing plate 1 to the inner wall, the strength of both side walls connecting the main beam 12 and the auxiliary beam 14 of the support column 10 can be increased.

The reinforcing spacer 2 is formed by integrally forming a cylindrical insertion part 6 having a through hole 6a for passing the through bolt 3 on both sides of a fixed part 5, as shown in the figure. The fixing portion 5 is provided with two screw holes 5a, 5a into which fixing bolts 9 are screwed. Further, the insertion portions 6, 6 are connected to the through holes 4 of the support column 10 and the reinforcing plate 1.

When connecting the main beams 12, first, the reinforcing spacers 2 are fixed to the ends of the main beams 12 and then inserted into the notches 10a of the support columns 10. Next, align the through holes 4a and 1a of the pillar 10 and the reinforcing plate 1 with the through holes 12a and 6a of the main beam 12 and the reinforcing spacer 2, and pass the through bolt 3 through the through holes 4a, 1a, 12a, and 6a. . Then, by tightening the through bolt 3, the reinforcing plate 1 and the reinforcing spacer 2 are held in place. Through the above steps, the support column 10 and the main beam 12 are connected.

When connecting the auxiliary beam 14, the end of the auxiliary beam 14 is inserted into the insertion hole 10b of the column 10, and the through hole 4b of the column 10, the through hole 1b of the reinforcing plate 1, the through hole 14a of the auxiliary beam 14, and the reinforcement The spacer 2 is aligned with the through hole 6a, and the through bolt 3 is passed through and fastened in the same manner as in the above case.

In this embodiment, since the elongated reinforcing plate 1 is used as described above to connect the main beam 12 and the auxiliary beam 14 to the support column 10, the entire upper and lower connecting portion of the main beam 12 and the auxiliary beam 14 is can be reinforced at the same time.

Note that the present invention is applicable not only to the carport shown in the embodiment, but also to the connection of hollow supports and hollow beams in balconies, terraces, etc.

In this embodiment, the reinforcing plate 1 is fixed to the left and right inner walls of the support column 10, but it may be fixed to only one inner wall. Further, the shape of the reinforcing plate 1 may not be long as in the embodiment, but may be short if the hollow beam is a single piece.

In this embodiment, the reinforcing spacer 2 has a shape that has a pair of insertion parts 6 on both sides of the fixed part 5, but this reinforcing spacer 2 has a cross-sectional area that allows surface contact between the side walls of the hollow beam material. It may have any shape as long as it has a through hole. For example, it may be cylindrical with a round or square cross section. Further, the number of through holes is not limited to two, but may be one or three or more.

[Effects of the invention] As explained above, the present invention fixes the reinforcing plate to the inner wall of the hollow support, fixes the reinforcing spacer inside the hollow beam, and attaches the reinforcing plate and the reinforcing spacer to the inner wall of the hollow support. By clamping and fastening, the through bolt can be strongly tightened, and the connection strength between the hollow support and the hollow beam can be strengthened. Further, since the reinforcing plate and the reinforcing spacer are clamped in surface contact between the side walls of the hollow support and the hollow beam, it is possible to prevent the side walls from being deformed or damaged due to tightening. In addition, the load applied to the hollow support can be supported by the reinforcing plate, and the load applied to the hollow beam can be supported by the reinforcing spacer, making it possible to significantly increase the strength against the load compared to receiving the load by the wall thickness alone.

Further, since the reinforcing plate and the reinforcing spacer are fixed to the hollow support and the hollow beam member in advance, respectively, the connection work can be easily performed by simply passing through bolts and tightening them.
