Description

Connecting Structure of Supporting Beams

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strut connection structure for preventing collapse of a retaining structure such as a toe wall (hereinafter referred to as "toe wall ").

In construction of the earth retaining walls, soil walls and the like, a strut is installed to support the transverse earth pressure. The strut is mainly used as a strut, and a plurality of beams are used when necessary.

FIG. 1 is a schematic perspective view showing a state in which a soil wall is supported by a strut, and FIG. 2 is a detailed view of a circle A in FIG. 1 and is a schematic diagram showing a connection structure of a strut in detail according to a conventional art.

To prevent collapse of excavation paper, a vertical beam 3 is inserted into the excavation paper as shown in Fig. Then, the panel 5 is laminated between the inserted vertical beam 3 and the vertical beam 3 to construct the toothed wall 1. Such a wall 1 is designed to withstand the earth pressure itself, but when the earth pressure is large, a force is required to support the wall 1 so that it does not collapse. In order to support the toothed wall 1, the strut 10 is provided between the opposed toothed walls 1 to reinforce the toothed wall 1.

In order to support between the facing walls 1, the strut 10 must have a length corresponding to the distance between the walls 1. When the length of the strut 10 is shorter than the interval, as shown in FIG. 1, And a short strut 10 is connected to be used.

Fig. 2 is a detailed view of the circle A in Fig. 1, showing a state in which a strum boat having a short length is connected by a conventional method.

In the construction site, a short strut 10 is connected in order to form a strut having a length corresponding to the distance between the strut walls 1. In general, the beam used as the strut 10 includes an end plate 14 in addition to the upper flange 11, the lower flange 13 and the web 12 and a side surface 14 for reinforcing the end plate 14. [ A reinforcing rib 15 is provided. The end plate (14) is welded to the end of the strut (10) by fillet welding.

The end plate 14 and the reinforcing rib 15 are welded in the field.

A plurality of through holes are formed in the upper flange 11 and the lower flange 13 at the ends of the strut 10 to connect the strut 10 and the strut 10 to be connected is connected to each end plate 14 are in contact with each other. A through hole is also formed in the end plate 14. A connecting plate 20 made of a steel plate is coupled to the upper flange 11 and the lower flange 13 of the strut 10. The connecting plate 20 has a through hole formed in an end of each strut 10, A through hole is drilled at the corresponding point.

The upper and lower connecting plates 20 are positioned over the upper flange 11 and the lower flange 13 of the both strut brackets 10 in a state where the end plates 14 of the both strut brackets 10 are in contact with each other The bolts 22 are passed through the connecting plate 20 and the through holes formed in the upper flange 11 and the lower flange 13 of the strut brace 10 and then the nut 24 is fastened to the connecting plate 20 20 to the two strand ropes 10. Also, the end plates 14, which are in contact with each other, are also fastened to the end plates 14 by fastening the bolts 22 with the nuts 24.

The strut 10 connected in this way is in contact with the toothed wall 1 with its opposite ends facing each other to reinforce the toothed wall 1.

In the conventional strut connection structure, since the end plate 14 and the reinforcing rib 15 must be welded together at the time of connecting the beams, which are the main materials of the temporary site, the welding is not uniform, And it takes a long time to work on the site, which causes air delays.

In addition, welding work requires an experienced welding technician and requires additional welding site and equipment, further increasing the construction cost.

Also, the steel beam welded with the end plate and the reinforcing rib is difficult to be used for other purposes, and even if it is intended to be used as a strut in other fields, the length is not matched. Therefore, the end plate and the portion provided with the reinforcing rib are cut off, And the reinforcing ribs are welded together, so a lot of waste material is generated.
