Description

Reusable supporting bracket for furring strip}

The present invention relates to a strip support bracket used to support the strip of a retaining wall, and in particular, it is removed when the retaining wall is dismantled and can be reused. It relates to a belt support bracket that can be installed in response to the inclination of the belt length for the purpose, increases the installation safety by sharing the shear load, and enables use without sagging due to an increase in the number of reuses.

An earthen barrier is installed to dig in the ground. Since this retaining wall is subjected to earth pressure, a strip is installed, and the strip is supported by a strip support bracket installed on the thumb pile of the retaining wall. Therefore, the belt length resists the bending moment and shear force caused by the earth pressure acting on the wall of the retaining wall. When an earth anchor is installed on this strip, it is installed with an inclination angle, and for this purpose, there are times when it is necessary to adjust the inclination of the strip support bracket. In general, the strip support bracket is installed by welding to the thumb pile of the earthen wall at the site, and then dismantled and discarded when the strip is removed. As such, since the belt support bracket cannot be reused, there is a problem that not only wastes materials but also does not help to reduce construction costs. Therefore, there is a need for a technical plan for the reuse of the strip support bracket.

As a background technology of the present invention, as Korean Patent Registration No. 10-1420374,'H-beam belt support bracket' has been proposed. This makes it possible to effectively prevent damage to the bracket against the external force applied to the bracket from the strip length, and minimize the horizontal displacement of the strip length. However, while the above background technology has a solid structure, there is no technical alternative to reuse to reduce the installation cost of the H-beam strip support bracket.

As another technology that serves as the background of the present invention, Korean Patent Registration No. 10-1683968 has been proposed, and a'band-length bracket' has been proposed. This is to prevent sagging or deformation by the support brace so that the support and safety can be improved so that the belt can be mounted, and it can be easily installed and removed from the pile, thereby improving work efficiency. However, in this background technology, the belt bracket can be installed only at the upper end of the pile, and there is a problem that it cannot be installed in several places depending on the excavation depth of the excavation. In other words, it has a disadvantage that the belt length bracket cannot be installed in the middle to be installed along the depth of the pile. In addition, there is a problem that it is impossible to install the strip in an inclined manner for the construction of the earth anchor because it is impossible to adjust the angle on the strip bracket.
