Description

[Detailed description of the invention] This invention relates to a beam/square beam connection structure that orthogonally connects a square beam to the side surface of a beam, and aims to stabilize the mounting strength of the square beams and facilitate their installation.

An embodiment of this invention is shown in FIGS. 1 and 2.

In other words, this beam/square beam connection structure consists of a beam 1 made of approximately section steel, and upper and lower flanges l of the beam 1 from the bottom piece 2b to the side pieces 2a.
A fitting groove 3 is provided at a height approximately equal to the distance between a and lb, and the upper flange 1a of the beam 1 is fitted into this fitting groove 3, and the bottom piece 2b is placed on the lower flange 1b of the beam 1. The beam 1 includes a U-shaped metal fitting 2 that is attached to the beam 1, and a square piece 5 that fits into the recess 4 of the U-shaped metal fitting 2 and is attached perpendicular to the side surface of the beam 1 (i.e., the web lc). .

In this case, the length of the square timber 5 is equal to that of the two sides of the U-shaped fitting 2.
The height is the same as that of beam a, and its end face is the upper flange 1 of beam 1.
It is installed in contact with the a end face.

Furthermore, nail holes 6 for fixing the square timbers 5 are provided in both side pieces 2a of the U-shaped metal fitting 2.

With this configuration, the installation of the square timber 5 to the beam 1 is as follows:
As shown in FIG. 2, the upper flange 1a of the beam 1 is fitted into the fitting groove 3 provided in the U-shaped fitting 2, and the bottom piece 2b of the U-shaped fitting 2 is placed on the lower flange 1b of the beam 1. Then, as shown in FIG.
This can be done by inserting the nail 7 into the square timber 5 through the nail hole 6 provided in the U-shaped metal fitting 2.

In this way, by simply fitting the fitting groove 3 of the U-shaped metal fitting 2 into the upper flange 1a of the beam 1, inserting the square lumber 5 into the recess 4 of the U-shaped metal fitting 2, and fixing it with a nail, the square lumber 5 can be attached very easily. can be orthogonally connected to the side surface of the beam 1.

Also, insert the fitting groove 3 into the bottom piece 2b on both sides 2a of the U-shaped fitting 2.
Since the fitting groove 3 is provided at a height approximately equal to the distance between the upper and lower flanges la and lb of the beam 1, the fitting groove 3 is located at the upper part 7 of the beam 1.
When fitted onto the flange 1a, the bottom piece 2b of the U-shaped fitting 2 is placed on the lower flange 1b of the beam 1, and as a result, the load of the square timber 5 is divided into two parts, the upper flange 1a and the lower flange 1b of the beam 1. Since it is supported, the mounting strength of the square timber 5 is also stabilized.

Further, since the U-shaped metal fitting 2 can be attached to any position along the length of the beam 1, the square timber 5 can be attached to any position on the beam 1.

Note that this beam/square beam connection structure can be used for applications such as for example.

That is, in order to provide the storage space 8 shown in FIG. 3 in the attic (its range is shown by a set of dots), the storage space 8 is placed on the beam 1 serving as the roof beam, as shown in FIGS. 4 and 5. This is the case when installing a large square beam 5 to hold the floor 9 of the building.

10 is a joist. As described above, the beam/square beam connection structure of this invention consists of a shaped steel beam having upper and lower flanges that extend horizontally and face each other, and a bottom piece on both sides to adjust the spacing between the upper and lower flanges of the shaped steel beam. a U-shaped metal fitting that has fitting grooves at substantially equal height positions and is attached to the beam by fitting the upper flange of the beam into the fitting groove and placing a bottom piece on the lower flange of the beam; Since it is provided with a square piece that fits into the recess of the U-shaped metal fitting and is installed orthogonally to the side surface of the beam, it has the effect of stabilizing the mounting strength of the square piece and making the installation easier.
