The present invention relates to a divided application of the invention patent application No. 10-2008-0042639, and more particularly, to an anchor support which is built between the strips when constructing a strip and an anchor support for supporting the earth wall and an installation method using the same.

Characteristic of the present invention, the horizontal pile is above. The anchor member is composed of the fixing member and the fixing bracket so that the anchor supporting member can be combined to be united by being inserted between the belt and the string member which are structured in the lower stage. By fixing the fixing bracket with the fixing member, the fixing member supports the belt and at the same time minimizes the distance between the retaining wall and the support for supporting the wall.

In general, in the case of excavation of the ground during civil engineering work, temporary soil wall on the excavated ground to prevent soil from entering or digging into the excavated portion formed as the boundary of the excavated portion (aka: earth wall Construction to compensate for the collapse of the soil.

The temporary wall is constructed by a variety of methods, but in general, the H-shaped piles are placed on the ground at a certain distance, and the earth wall is formed by stacking wooden earth plate between the H-shaped piles, and the earth wall is constructed. After that, in order to support the entire earth wall so as to receive uniform earth pressure, a horizontal support made of H-shaped pile is installed to form a band, and an earth anchor is installed between the band and the band.

The edge part was bitten by the fixing tool 3, and was fixed to the said pressure plate 2. However, in the conventional construction as described above, as the pedestal 1 supporting the end of the anchor is installed to protrude to the outside of the belt strip 101, the excavation space is reduced as much as the pedestal 1 protrudes, so that space utilization is efficient. When the concrete is poured by stacking the formwork to the front of the earth wall where the pedestal (1) is installed, the thickness of the wall should be increased by the distance between the pedestals protruding from the belt, so that the construction cost is increased due to the large amount of concrete. Of course, a problem arises in that the use site due to the trench is further secured by the interval of the protruding pedestal 1.

The present invention has been made to solve the problem caused by the pedestal installed for fixing the end of the anchor and support from the earth wall as described above to protrude to the outside of the two belts, to support the anchor wall and to support the anchor The anchor support is installed, but the anchor support can be installed in such a way that it can be installed integrally between the belt and the belt to make efficient use of the excavation space, as well as to lose the tensile force obtained from the anchor through the anchor support provided. The object of the present invention is to provide an anchor support and an installation method using the same, which can be transferred to and supported as an earthen wall.

In order to achieve the above object, the present invention is provided with a fixed plate through which several coupling holes are drilled, and a side plate is welded to one end of the fixing plate to form a right angled portion, and a through hole is formed at the center of the right triangular shape, and the front hole is fitted with holes. The plate is welded to the right angled part formed by the side plate and the fixed plate, and the base support plate formed with the horizontal bar protruding at the center of the vertical bar to weld the front plate and the side plate on the back is welded and the half shape is symmetrically engaged. A pair of fixing brackets installed in a structure; An acupressure plate installed on the front plate of the fixing bracket and having a fitting hole formed on a rear surface thereof, and having an angle adjustment tool integrally coupled to the front surface thereof; A support plate is formed through which a plurality of coupling holes are drilled so as to couple the fixing brackets at the upper and lower sides of the strip, and a pair of support pieces having a vertical plane and an inclined plane to one side of the support plate protrude integrally at predetermined intervals. It is possible to provide a new anchor support and an installation method using the same by constituting the anchor support composed of the fixing member so that the anchor support is installed in between the bands where the horizontal pile is installed in two stages. It becomes possible.

Due to the configuration of the anchor support according to the present invention, the member for supporting the anchor does not protrude to the outside of the belt, and is installed in a form sandwiched between the belts, thereby preventing the excavation space from being narrow and efficiently utilizing the drilling space. The cost can be reduced.

In addition, it is possible to transfer the tension force from the anchor to the retaining wall without loss, so that the retaining wall can be sufficiently supported to endure earth pressure.

The present invention relates to an anchor support which is built between the belts and an installation method using the same. Several vertical piles are erected at regular intervals in order to prevent the drilling surface or soil from collapsing due to the excavation of the ground, and the earth plate between each vertical pile. In order to install a wall of mud wall by stacking the wall, and to install a support made of a horizontal pile strip and earth anchor to support the wall to be able to stand free from earth pressure,

 Anchor support is built in the hole, and the anchor support for fixing the steel wire is composed of the front of the retaining wall, the horizontal pile is above. The anchor supporting member is composed of a fixing member and a fixing bracket so that the anchor supporting member can be integrally coupled between the belt and the belt structure having two stages below. It is possible to minimize the gap between the wall and the support to support the wall when constructing the wall by constructing the installation structure to fix the fixing bracket and to support the fixing bracket at the same time. It is possible to reduce the amount of concrete, to reduce the site area at the time of digging to secure the use site, as well as to provide an effect of increasing the use site.
