Description

Bracing connector and bracing assembly comprising same

The present invention relates to a brace connector, and more particularly, to a brace connector used to connect a brace that provides support to a wale of a retaining wall installed to support earth pressure in excavation work, and a brace assembly including the same.

In excavation work for infrastructure such as subways, buildings, underpasses, and underground storage facilities, retaining work to support the earth pressure is carried out on the periphery of the excavated site.

Retaining construction is a construction for the purpose of resisting lateral pressure such as earth pressure and water pressure that occurs during underground excavation. The field of use is diversifying.

The retaining work is carried out together with the excavation work. In general, during retaining construction, retaining posts made of H-beams at arbitrary intervals are erected perpendicular to the ground, and a plurality of retaining plates are stacked and inserted between adjacent retaining columns to form a retaining wall supporting an earthen wall or a rock wall. . Then, the retaining wall is made to withstand earth pressure by connecting the wale to the pole in the transverse direction, and connecting the wale facing each other with a brace.

The brace is to effectively support the earth pressure acting on the retaining wall to prevent the soil from being lost or collapsing in the excavated earth wall, and is generally arranged at regular intervals. It is also possible to adjust the length of the brace by fastening a connection jack to the connection part of the wale and the brace. Conventionally, H-beams have been mainly used as braces. However, the H-beam is prone to buckling and has a large weight, so the use of steel pipe-shaped braces is increasing recently.

A connector connecting the brace to the braid or a brace connector is required to connect it with other braces. However, the conventional brace connector has a problem in that it is inconvenient to use because the connection work is cumbersome, and the construction time is long.
