Description

[Detailed description of the invention] The present invention relates to a beam connection structure, and its gist is that beam connection parts 2 are provided on the side surface of the main beam 1 at regular intervals in the longitudinal direction of the main beam 1, and The secondary beams 4, which are arranged at right angles to the main beam 1 at intervals, are connected to the beam connection parts 2, respectively, and the preliminary beam connection parts 3 are connected to the beam connection parts 2.
is attached to the beam connection part 2, and the beam connection spare part 3 is connected to the main beam 1.
A beam formed by fixing to the beam connection part 2 and the beam connection spare part 3 a sub-beam 5, which is fixed to the beam connection part 2 and the beam connection spare part 3 and is arranged at a different interval from the beam connection part 2, spanning the beam connection part 2 and the beam connection spare part 3. in the connection structure.

Generally, when connecting beams to each other, beam connecting parts are provided at regular intervals on the main beam, and secondary beams are arranged at right angles at the same intervals as the beam connecting parts to connect the secondary beams and the beam connecting parts. , if the secondary beam 4 is misaligned due to design reasons, conventionally, as shown in Figure 1,
The secondary beam 4 is connected to the main beam 1 by only one bolt 6 at the beam connection portion 2, which has the disadvantage that the joining force is halved.

The present invention was developed in view of these drawbacks, and its purpose is to create a beam that can completely fix the displaced beam in the same condition as a normal beam, even if the beam is misaligned. Provides a connection structure.

Hereinafter, the present invention will be described in detail according to illustrated embodiments.

As shown in Fig. 2, the main beam 1 is like a lattice beam in which an upper frame 7 and a lower frame 8 are connected by reinforcing bars 9, and there is a beam connection between the upper frame 7 and the lower frame 8. 2 are arranged at regular intervals in the longitudinal direction of the beam 1, and the upper and lower ends of the beam connection part 2 are connected to the upper frame 7 and the lower frame 8.
are welded to each other, and two rows of bolt holes 10 are bored at the top and bottom of the front surface of the beam connection part 2.

As shown in Fig. 7, the beam connection spare part 3 has a top plate part 12, a bottom plate part 13, and a reinforcing plate part 14 disposed in three upper and lower stages between both side plate parts 11, and the joints of each part are welded. be.

Further, the upper and lower ends of both side plate portions 11 are tapered inward, and these portions are defined as fixing surface portions 15.

Also, between the fixing surfaces 15 is a beam mounting surface section 19, and bolt holes 10 are bored in the beam mounting surface section 19 and the fixing surface section 15.

The sub-beam 4 is short and has a connecting face plate 16 welded to its end.

As shown in FIG. 6, two main beams 1 are first arranged in parallel, and sub-beams 4 are arranged at right angles between them at regular intervals, and the connection face plate 16 of the sub-beams 4 is attached to the beam connection part 2. The floor beam A is formed by bolting, and then building the places 17 in a cross manner.

Next, when connecting another small-sized floor beam B to the above-mentioned floor beam A, some of the sub-beams 5 have to be spaced differently from other sub-beams 4 due to design considerations, which may cause misalignment. As shown in Figures 4 and 5, the beam connection spare part 3 is arranged along the beam connection part 2, and the upper and lower ends of the beam connection spare part 3 are connected to the upper frame 7 and the lower frame 8. Bolt.

At this time, since the fixed surface portion 15 of the beam connection preliminary portion 3 is bent inward, the beam attachment surface portion 19 is flush with the upper frame 7, the lower frame 8, and the beam connection portion 2.

Next, as shown in Figure 4, half of the beam connection part 2 and the beam connection spare part 3 are connected.
Connect the connecting face plate 16 of the sub-beam 5, which is disposed astride the two, to the half of the beam connecting part 12 and the beam connecting spare part 3 with bolts 6 and nuts 18.
It will be fixed in place.

As mentioned above, the present invention provides beam connection parts on the side of the beam at regular intervals in the longitudinal direction of the beam, connects sub-beams arranged at the same intervals as the beam connection parts to the beam connection parts, and The secondary beams, which are arranged at different intervals from the connection part, are installed across the beam connection part and the spare beam connection part, which is placed along the spare beam connection part, so one sub-beam is placed at a different interval from the connection part. Even if a beam is misaligned, it can be connected to a sub-beam with a different spacing just like a normal sub-beam.
This has the advantage that the connection strength of sub-beams with different spacings is not reduced.
