Connector with insertion groove for wale and strut of earth retaining wall}

The present invention relates to a connection device used in a method of supporting a retaining wall during construction, that is, a retaining wall with a support structure, and more specifically, a combination of a wale and a brace, or a combination of a connection jack and a brace installed on a wale, or When the beotimbo and the beotimbo are combined or the connecting jack installed in the beotimbo and the beotimbo are coupled, the end of the beotimbo is inserted into the insertion groove and installed, and the beotimbo is smoothly released when the beotimbo is removed by filling or installing a cushioning material in the insertion groove. It is possible to minimize distortion and deformation when fastening bolts by forming male and female coupling parts on each coupling surface of the connecting device coupled to the wale or connecting material, and to increase the coupling force through the connecting support or auxiliary fastening protrusion to make it stable and stable. It is a technical field related to a retaining strip and a support connecting device in which an insertion groove is formed to form a solid retaining wall.

As urbanization progresses, buildings are becoming higher in order to increase the utilization rate of land, and accordingly, the depth of excavation work is also increasing to secure more underground space.

When performing such underground excavation work, a retaining wall is installed to prevent the collapse of the surrounding soil due to lateral pressure such as earth pressure or water pressure. The installation of these retaining walls is essential in cities to prevent collapse of surrounding buildings or subsidence of the ground.

The installation method of the retaining wall is classified in various ways according to the type of wall forming the retaining wall and the supporting structure supporting it. The wall is composed of thumb piles, earth plates, sheet piles, column piles, underground continuous walls, etc., and the support structure is composed of a support type, raker type, anchor type, soil nailing type, etc.

Among the support structures, the anchor type supports the retaining wall inside the soil, so that no obstacles are formed on the site, so it has the effect of improving workability. do.

For example, in Korean Intellectual Property Office Registration No. 10-1540153 (hereinafter referred to as 'Prior Document 1'), a wale installed on a retaining wall made of thumb piles and earth plates and supported by struts is has been initiated.

By the way, Prior Art Document 1 provides a wale in which a beam reinforcement applied to a corner of a retaining wall installed at a corner of a construction site is integrated with a horizontal member. This has a disadvantage in that the time required for installing the retaining wall increases because it goes through a process that must be pre-assembled in accordance with the scale at the site.

In addition, in Prior Art Document 1, since both ends of the beam reinforcement are connected by pins, it may be vulnerable to shear failure of the pins when strong earth pressure is applied to the retaining wall.

In addition, in the support structure, the support supporting the earth pressure for the retaining wall is supported in the direction perpendicular to the wale, so when the direction in which the earth pressure is applied is changed, the distribution of the earth pressure is uneven, or part of the earth retaining wall When the direction of the earth pressure and the direction of the brace do not match when the direction of the earth pressure is damaged, the brace is buckling and deformed, resulting in expansion of damage or collapse of the brace structure.

In addition, when connecting the wale and the brace, excessive rotation of the bolt during fastening by the bolt causes the wale and the brace to buckle and deform, resulting in damage or distortion, which lowers the bonding strength between the wale and the brace, causing the retaining wall to collapse. also became

Republic of Korea Patent No. 10-1812451 (2017.12.19.)

The present invention is a technology devised to solve the problems caused by the prior art, and the connection device used in the conventional support structure is difficult to dismantle the brace due to strong adhesion for a long time during demolition after construction, bolts fastened during construction Twisting or deformation may occur between wales or braces due to the strong coupling of the, and the coupling force may be lowered, and the problem of not enduring continuous earth pressure due to the connection structure simply by bolt fastening occurs;

The installation and disassembly of the brace is facilitated by the insertion groove of the brace formed in the body and the cushioning material filled or installed in the insert groove, and the male and female coupling part is formed correspondingly on the coupling surface of the connecting wale, connecting material and connecting device to prevent twisting and Deformation can be minimized, and adjacent braces are connected with connecting supports and moving and connecting reinforcements to prevent buckling due to earth pressure acting on the braces, and insertion of braces is easy through auxiliary fastening members protruding from the body, making construction easier. The main purpose is to provide an earth retaining wale and a support connecting device with a simple insertion groove.

In order to achieve the above object, the present invention is a connecting device installed on a wale or connecting material, a flange portion coupled to the wale or connecting material and a protruding portion formed on one side of the flange portion, and a brace is inserted and fixed. It is characterized in that it comprises a body having an insertion groove formed therein, a cushioning material filled or installed on the lower surface of the insertion groove, and a moving and connecting reinforcing part formed to protrude from the outer surface of the body and having a ring hole formed therethrough. Suggest a furring strip for earth retaining with an insertion groove and a brace connecting device ffm.

In addition, the flange portion of the present invention includes a plurality of male and female coupling portions formed convexly or concavely on the other side, and the wale or connecting member is formed convexly to correspond to the plurality of male and female coupling portions formed on the flange portion. It is characterized in that it is configured to include a plurality of corresponding coupling portions formed concavely.

In addition, the moving and connecting reinforcement part of the present invention is protruded so that the ring hole is located outside the end of the flange part, including a connection support connecting the moving and connecting reinforcement part and the moving and connecting reinforcement part of the adjacent beotimbo, It is characterized by being composed.
