Description

[Detailed description of the invention] The present invention relates to a cantilever beam mounting structure in which a cantilever beam is attached to a cantilever support member fixed on the top of the beam, and improves joint strength. This is to prevent deformation of the girders and columns.

Conventionally, the horizontal piece of the cantilever support member is fixed on the top of the girder, and the gravity of the cantilever beam is transmitted through the connection with the cantilever support member and is concentrated on the girder and the columns that support this girder. Load is added,
In particular, there was a problem that the column would deform unless the cross-sectional moment of the column was appropriately large.

The present invention was developed against the background of the above-mentioned circumstances, and is intended to be applied to a cantilever beam mounting structure in which a cantilever beam is fixed to a cantilever beam support member fixed on the top of a girder. horizontal piece,
The present invention provides a cantilever beam mounting structure characterized in that the cantilever beam is fixed on the tops of the main beam and the small beam.

Hereinafter, the present invention will be explained in detail based on the drawings.

For example, as shown in FIGS. 1 and 2, a large beam 3 and a small beam 4 attached across the large beam 3 are fixed on the pillar 5, and the tops of the large beam 3 and the small beam 4 are fixed. A cantilever support member 1 is fixed across the top.

In other words, this cantilever support member 1 has a vertical piece 1d and a vertical piece 1d.
A horizontal piece 1a consisting of a horizontal piece 1e that crosses the horizontal piece 1e, and a rising piece 1 rising vertically from the outer edge of the vertical piece 1d of this horizontal piece 1a.
In order to prevent the rising piece 1b from tipping, it is supported from the side of the horizontal piece 1e by a bent piece 1c having a F-shaped cross section.

The vertical piece 1d of the horizontal piece 1a is placed on the top of the main beam 3, and the horizontal piece 1e is placed over the top of the main beam 3 and the small beam 1, and fixed on the top of the small beam 4 and the large beam 3. has been done.

The rising piece 1b of the cantilever support member 1 fixed in this way
is fixed by bolting a vertical plate 2a provided at the fixed end of the cantilever beam 2, so that the gravity of the cantilever beam 2 is also borne by the small beam 4.

Moreover, FIG. 3 shows the rising piece 1b of the cantilever support member 1 and the cantilever beam 2.
The mounting piece 2a is considered to be one part.

Note that 6 shown in FIGS. 1 and 2 is a reinforcing washer that is attached when the large beam 3 and the small beam 4 are thin.

As described above, according to the cantilever beam support structure of the present invention, the gravity of the cantilever beam is transmitted to the small beam by the cantilever support member, reducing the gravity applied to the girder and columns, and reducing the gravity to the small beam. By increasing the load, it is possible to strengthen the bonding force between each member and to reduce deformation of the girders and columns.
