Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a beam joining structure that improves workability for attaching small beams and purlins.

[Background Art] Conventionally, as shown in FIGS. 8 and 9, a small beam 5
The gusset plate 15 is fixed to the end of the main building 6, and the small beam 5, etc. is fixed to the vertical piece 4' of the hardware 1'. ,
During construction, set plate 15 as shown in Figure 8.
hit the reinforcing ribs 16 of the girder 3, and as shown in Figure 9, the bolts 11 fixing the metal fittings 1' to the girder 3 hit the bolts 11, making it difficult to get close to the metal fittings 1'. One of the bolts 11 had to be attached later, which required a lot of work.

[Effect of the Invention J The present invention has been made in view of the above circumstances, and its purpose is to improve the workability of attaching a small beam or a main building to a main beam.

[Disclosure of the Invention] In the beam joining structure of the present invention, the approximately T-shaped small beam is attached using hardware 1.
Fix the horizontal piece 2 to the side of the girder 3 and make the vertical piece 4 stick out from the girder 3 in a perpendicular state. This configuration achieves the above objective.

The present invention will be described below based on embodiments shown in the accompanying drawings. Reference numeral 1 denotes a metal fitting for attaching a small beam having a substantially T-shape, and as shown in FIG. 7, two bolt insertion holes 9 are bored in each side of the horizontal piece 2. To install the small beam, the vertical piece 4 of the hardware 1 is welded together with the separate connecting piece 4a and the mounting piece 4b.For installation, cut out the center part of the piece 4b, and use the piece 7 for the lower installation and the piece 7 for the lower installation. 8 is formed. Two mounting holes 10 are drilled in each of the lower mounting piece 7 and the lower mounting piece 8. Bolts 11 are fastened to the web 3a of the large beam 3 made of H-beam 3 using the horizontal piece 2, and the vertical piece 4 is placed vertically. It stands out from the 7Runno 3b. To attach the small beam 5, which is made of H-shaped steel of the same size as the large beam 3, using the hardware 1, as shown in Figures 1 to 3, the webs 5a at each end of the small beam 5 are For installation, the hardware 1 is attached by abutting against the piece 4b, and for example, for lower attachment, the upper part of the piece 7 is attached through the hole 10a, and for the lower attachment, the lower part of the piece 8 is attached by using the bolt 13 through the hole 10d. To install the main building 6, as shown in Figs. 4 and 5, the webs 6a at each end of the main building 6 should be attached to the lower beam 7 of the metal fittings 1, and the webs 6a at each end of the main building 6 should be in contact with the lower piece 7 of the hardware 1, and the mounting holes should be 10a, 101+ and fasten with bolts 14. In this case, the 7 runci 6b on the lower side of the main building 6 can be located in the notch 12 between the pieces 7 and 8 when vertically installed, which will hinder the installation of the main building 6, which is made of H-beam steel that is not the same size as the girder 3. Never. In addition, as shown in Figure 6, the main building 6 is attached to the lower beam of the hardware 1 through the holes 10c and 10d.
It may also be attached via. In this case, 7 above the main building 6
Lunge 6b is located within cutout 12. 17 is a pillar.

[Effects of the Invention] In the present invention, when attaching a substantially T-shaped small beam fixed to the side of a large beam, the vertical piece of hardware is vertically protruded from the main beam, so that this protruding small beam is fixed to the side of the main beam. Beam installation is done by fixing the ends of the small beams and purlins through vertical pieces of hardware, which eliminates the need to use set plates as in the past, reducing the number of parts, and also making it possible to By simply attaching the following items, the workability of B1 can be significantly improved.
