Description

Brace connector {CONNECTION DEVICE FOR STRUT AND CONNECTION APPARATUS FOR STRUT HAVING THE 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 connection device 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 vertically with respect 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.

The fixing plate 110 is connected to the body 107 so as to be disposed around the body 107 . The fixing plate 110 has a bonding surface 111 to which the end of the brace 10 is bonded. The end of the brace 10 to the joint surface 111 may be joined in various ways, such as welding. The bonding surface 111 may take various forms that the end of the beotimbo 10 can be in contact with, or a flat type as shown so that the end of the beotimbo 10 can be stably joined. The fixing plate 110 has a plurality of openings 112 spaced apart from each other along the circumference of the body 107 . The fixing plate 110 is disposed at a position somewhat spaced apart from one end of the body portion 107 . Accordingly, one end of the body portion 107 protrudes from the bonding surface 160 of the fixing plate 110 . The diameter of the fixing plate 110 is larger than the diameter of the flange 120 .

The flange 120 is connected to the other end of the body portion 107 so as to be spaced apart from the fixing plate 110 . The flange 120 is disposed parallel to the fixing plate 110 . Flange 120 has a coupling surface 121 that can be in contact with the other beotimbo connector 105, or various connecting mechanisms for connection with the beotimbo 10, such as the connecting jack 150, or the wale 20. The coupling surface 121 may take various forms that can be in close contact with the flat type as shown, or other brace connector 105 or the connection jack 150, the wale 20, and the like.

A plurality of fastening holes 122 are formed in the flange 120 . The fastening hole 122 is formed at an edge portion of the flange 120 to penetrate the flange 120 . One side of the fastening hole 122 is opened to the outside of the flange 120 , and the other side of the fastening hole 122 is opened toward the side groove 132 provided between the plurality of reinforcing parts 130 . In the fastening hole 122 , a bolt 30 for fixing the other brace connector 105 or the connection jack 150 , the belt 20 and the like to the flange 120 may be inserted.
