{Connecting structure of steel pipe strut}

The present invention relates to a steel pipe reinforcement connection structure, more specifically, to prevent the collapse of the earth wall connecting the steel pipe reinforcement is installed between the H (pile) to the band, and the steel pipe reinforcement connecting the steel pipe reinforcement and the steel pipe reinforcement It's about structure.

After the ground is excavated to build the foundation, basement or concrete wall of the underground building at the construction site, the earth block is constructed to prevent the collapse of the excavated surface by earth pressure.

These mudguards are formed in the earth wall to support the pit soil surface in the H pile installed on the ground at predetermined intervals, and a plurality of bands are horizontally installed at regular intervals up and down on one side of the H pile, between the bands and the bands facing each other. The brace is installed horizontally at regular intervals.

At this time, when the spacing between the H-files is relatively far apart, the brace and the brace is horizontally connected between the girdle and the girdle.

The support belt is maintained at a predetermined interval by the support beam so that the earth wall withstands the earth pressure. At this time, a connecting jack is installed between the support belt and the support beam to closely contact the support wall installed in the direction of the earth wall. .

However, conventionally, H-beam is used as a brace, and when connecting the H-beam brace, the H-beam brace and the base plate are welded. Therefore, when transporting to the site, the distortion of the base plate occurs, and the quality is degraded by the welding of the site. It is difficult to secure the safety of the worker, there was a problem that the economic loss and air delay due to the inconvenience of adjusting the length during recycling.

In addition, when using the H-beam as a brace, buckling occurs in the weak axis (Y-Y) direction of the H-beam brace, there was an inconvenience to install the reinforcement horizontally and vertically to reinforce it.

Therefore, there is no difference in stiffness in each direction, and it is necessary to use a steel pipe brace having excellent compressive stiffness and a new connection structure for the steel pipe brace.

The present invention has been made to solve the above-described problems, the present invention is a smooth connection of the steel pipe reinforcement has no difference in direction rigidity and excellent compression stiffness, to provide a simple and convenient steel pipe reinforcement structure for earthwork construction The purpose is.
