Description

TOE board system {TOE BOARD SYSTEM}

The present invention relates to a top board system.

Typically, high-rise apartments or multi-story buildings use concrete to form the skeleton of the building. Most of the conventional methods for installing the concrete include installing a reinforcing structure in a predetermined shape, fixing a mold formed by assembling a plurality of wooden panels on the outside of the reinforcing steel structure, installing a scaffold outside the molding, And concrete is poured into the inside. Generally, a scaffold installed at the time of construction of a building is provided with a horizontal pipe on a vertical pipe, and a safety scaffold for transporting building materials on a horizontal pipe or forming a work space of an operator. A toe board standing upright at a predetermined height on the side surface is installed to prevent a foot drop or a fall of a building material.

Conventionally, in order to install the top board, a top board in the form of a panel is separately installed by welding or bolt fastening to the safety foot which is installed in accordance with the interval of the horizontal pipes. When the top board is welded, it is difficult to install and it takes a long time and it is difficult to reuse because it can not be separated. In case of bolt fastening, There is a problem that the time required is long.

Particularly, a horizontal pipe coupled to a vertical pipe is generally positioned in a state where an integral type of a hook or a separate fixing pin protrudes at an end portion. Since the conventional top board connection port is manufactured to be customized to the environment of the installation site, There is a problem in that it can not be used in a variety of places of use because it is difficult to cope with the fixing part of the horizontal pipe easily.

The matters described in the background section are intended to enhance the understanding of the background of the invention and may include matters not previously known to those skilled in the art.
