Description

[Detailed explanation of the idea] This invention relates to a beam joining device.

Conventionally, as shown in Fig. 1, a joining device for beams or large tensioners made of H-shaped steel, etc., fixes a fitting 3 with a butt-shaped cross section to a web 2 of a beam 1, and also connects other parts to be joined. An end plate 5 may be welded to the main drawer (or beam) 4, or a mounting plate 6 with bolt holes may be welded to the web 2 of the beam 1 as shown in FIG. )
Bolt holes are provided in the web portion of the web, and these are connected with bolts.

However, these devices require mounting hardware3. End plate 5
．． Since the mounting plate 6 and the like are required, there are problems such as a large number of five different types of parts, a time-consuming fixing process such as welding, and an increase in the weight of the beam material.

In addition, there are cases where it is necessary to weld the end plate 5 to the beam 4 and connect it via the end plate 5 as shown in FIG.
There are cases where it is necessary to directly join the web surfaces of the beams, but the joining devices shown in Figures 1 and 2 can only use one of the joining methods mentioned above, making it difficult to standardize component processing, manage component management, There is a problem of inconvenience during construction, etc.

Therefore, the purpose of this invention is to provide a joining device that requires fewer parts in the joining portions of horizontal members such as beams, has simple joining operations, and can employ two joining methods.

An embodiment of this invention will be explained based on FIGS. 3 to 9.

First, in the first embodiment of this invention, as shown in FIG. 3, cut and raised portions 9 are provided on both sides of the web 8 of the beam 7, which has a T-shaped cross section by joining two angles. Its tip is bent into an L-shape along the longitudinal direction of the beam 7, and bolt holes 10 are provided on each side.

Because of this, in order to join another beam 11 as shown in FIG.
It can be easily connected to the base 14 of the base 14, and also it can be easily connected to the L-shaped bent part 18 at the tip of the cut-and-raised part 9 with bolts 13 to connect to the beam 16 having the end plate 15. Can be done.

In this way, two joining methods can be freely selected, which is convenient for standardizing component processing, component management, and construction.

Further, in the second embodiment, as shown in FIG. is bent into a U-shape to form a rectangular tube standing upright in the direction of the flange 22, and bolt holes 23 are formed on each side of the U-shape.

The other beam 19' to be joined has a web 20' that projects in the longitudinal direction beyond the flange 22', and bolt holes 23' are provided in the projecting portion.

By doing this, other beam materials can be joined to any arbitrary surface of the U-shape in the same manner as in the first embodiment, and the joining strength can be increased.

Note that FIGS. 6 to 8 show proposed examples of beam joining devices.

That is, it can be manufactured extremely easily by simply cutting and raising the cut-and-raised portion 25 from the web 26 at right angles to the beam 24 and forming the bolt hole 27 therein.

In this case, a reinforcing plate 28 may be provided as shown in FIG.

As described above, the beam joining device of the present invention has a part that stands up from the web member and a part that extends perpendicularly from this part to the web member of the beam member that has a flange member and a web member. A cut-and-raised part is provided, and bolt holes are provided in each part of this cut-and-raised part, and the cut-and-raised part is connected to other beam materials, so the number of parts is reduced. There is less friction and the joining work is easy.
In addition, two types of joining methods can be used, making it convenient for standardizing component processing, component management, and construction.
