Description

TECHNICAL FIELD [0001] The present invention relates to a strut-

[0001] The present invention relates to a brace supporting device for a retaining structure, and in particular, in a bracket supporting brace on both sides of a corner portion of a retaining structure, a bracket bracket and a wale band are firmly connected by a pressing force of a screw jack, And more particularly to a strut brace for an earth retaining structure.

Generally, in the case of earthworks excavation, excavation works are carried out in order to prevent the soil of the ground formed at the boundary of the excavated part from entering the excavated part, To compensate for the collapse of the earth.

In order to compensate for the collapse of the gravel, a method is used in which a wall is formed on one side of the excavated soil and a screw jack is used for a support for supporting the wall of the formed clay. The movement of the membrane wall to the inside is prevented by using the H-shaped steel or the PC brace to prevent the gravel from being collapsed. However, there is a problem that the gaps occurring at various angles of the wale wall surface can not be completely installed.

Therefore, the soil contact touched by the wall of the soil is affected by elastic compressive deformation, creep deformation, and connection gap between the members due to the axial force between the soil plates of the strut due to the lateral pressure and the external lateral pressure. Or safety accidents. In order to prevent the change of the belt, generally, the H-shaped steel is cut and welded to reinforce the gap. However, this has the problem that the complete crevice compression can not be removed.

Especially, in the case of the fixing member fixing the wale located at the edge of the earth sand in the earthworks, it is necessary to increase the supporting stress by connecting the fixing members (H-shaped steel) to each other. However, Since it is not easy to change, the metal member according to the angle of inclination generated in the H-shaped groove and the scoot jack which fix the wedge is cut and welded to match the angle, so that the operation for fixing the wedge in the construction of the clay is considerably troublesome, And the metal member that has been cut can not be recycled, which leads to a waste of resources.

As a conventional prior art for reinforcing the corner portion in the existing padding structure, as disclosed in Korean Registered Utility Model No. 20-0393178 entitled " Member Fixture Having a Rotating Flare Bracket "(Registered on August 20, 2005) An upper fixing plate having a bolt hole and a rotation bracket formed with a pin hole and a lower fixing plate having a bolt hole and a rotation bracket with a pin hole formed therein, .

Another prior art for reinforcing the corners in the retaining structure is disclosed in Korean Registered Utility Model Registration No. 20-0393179 entitled "Screw Jack for Civilization with Rotating Flare Bracket" (registered on August 20, 2005) A lower plate having a bolt hole and a screw penetration portion and an upper plate having a screw inner portion and a rotation bracket formed with a pin through hole are connected to each other by a screw having a screw formed integrally with the screw and a screw formed integrally with the screw, A rotating bracket with a through hole formed therein and a member fixing plate formed with a bolt hole are coupled with a fixing pin.

The support bracket for supporting the retaining structure for the conventional earth retaining structure is provided with a flared bracket for supporting a wale portion provided on both adjacent sides of a corner portion by using a screw jack so as to support a corner portion of the retaining structure, It is troublesome to connect bolt fastening balls to the tie contact surface of the flared bracket by a plurality of bolts through the bolt fastening holes, and it takes a long time to work There is a drawback that the working efficiency is lowered.
