Description

Supporting member of the wall for soil barrier {Supporting member of the wall for soil barrier}

The present invention relates to a strut connection member for supporting a retaining wall, and more specifically, an upper connection member and a lower connection member are formed in a point-symmetrical shape, which can reduce material and manufacturing costs, and can reduce material and manufacturing costs. It is possible to prevent torsion due to the connection of the braces and secure rigidity at the same time by preventing the ends of the braces from contacting each other, and it is easy to dismantle. By combining a connecting member, it is a technical field related to a strut connecting member of a retaining wall that is easy to construct.

In general, ground excavation is performed during construction such as buildings, subways, power outlets, sewer pipes, civil structures, etc., and structures such as earth retaining facilities and earth walls are constructed to prevent collapse of the ground after excavation and to install underground structures, and A brace is installed to support it.

These braces mainly use H-shaped steel materials, and due to the limitation of transport length on the road, they are extended by connecting the braces to each other in the longitudinal direction at the site. At this time, a connecting jack or connecting member is used to connect the braces to each other.

As shown in FIG. 1, the conventional connecting jack or connecting member (hereinafter, collectively referred to as "connecting member") as described above is made to connect the two braces with a connecting plate and a reinforcing material after bringing the ends of the two braces together. In addition, the connecting plate and stiffener are bolted to connect the two braces.

However, since the conventional connecting member has a complicated structure for connecting the struts and the struts, and is composed of several divided bodies, it takes a lot of time for bolt fastening and disassembly, and it is difficult for the operator to connect the connecting member to the strut by himself. .

In addition, since the conventional connecting member has a structure in which only a part of the two struts is contacted and coupled, the axial force dispersion is not well achieved, so there is a problem in that deformation occurs in the connecting portion due to the axial force after connection.

As a prior art for solving the above problems, Korean Patent Registration No. 10-1597895 discloses that an H-shaped steel material used as a retaining beam for supporting a retaining wall is extended and connected to a connecting member in the longitudinal direction, but the connecting member It has both flange coupling grooves and web coupling grooves in the body to which both flanges of the H-shaped steel and the web in the center can be connected, and bolts are coupled to coupling holes formed on both sides of the body formed through the flange coupling grooves on both sides As a means of fixing the flanges on both sides, the connection structure and connection method of the retaining wall support struts that allow H-type steel materials to be connected simply and firmly are presented.

However, in the prior art as described above, the ends of the braces come into contact with each other, and as time passes, the ends of the two braces are integrated by strong pressure. Not only is it difficult to reuse, but there is a problem that deformation of the ends of the beotimbo and the beotimbo occurs.

In addition, in the prior art as described above, it is necessary to insert the beotimbo into the web coupling groove by moving the beotimbo horizontally when the beotimbo and the beotimbo are connected, but there is a problem in that it is difficult to insert the beotimbo having a considerable load into the web coupling groove.

As a prior art for solving the problem of integrating the braces and the deformation of the ends of the braces as described above, Korean Patent Registration No. 1502772 has cover-type upper and lower plates to resist the bending moment, and jacks inside the upper and lower plates It is installed to resist the compressive force, and by constructing a bulkhead to support the compressive force of the jack, it is possible to prepare for buckling that may occur in the brace, and to reduce the joint by placing the joint and jack installation location in one place when the brace joint occurs. It presents a member that receives a compressive force and a connecting material between the members.

However, the prior art as described above has a problem that the end of the brace can be deformed when the compression force of the brace is generated by the jack, and it takes time to install the jack and the compression brace bolt, which requires a lot of construction time.

In addition, in the prior art as described above, when connecting the braces to the braces, the two braces must be kept in a horizontal state and the connecting material must be combined in abutted state. However, in the case of a brace with a significant load, it is difficult to maintain a horizontal and abutted state. There is a problem.
