Abstract:
PURPOSE: A stay anchor is provided to regulate the depth of installation according to the unexpected geological features and to save a material cost as a lintel load device. CONSTITUTION: A board body is made up by combining a lower end of a lintel rod on a central upper end of a board having a slant guide line on both sides of an upper part. The lintel rods are combined in the multi-step of a straight line shape by the combination of twisting each other. A rib(26) formed by being compressed on a central line of vertical length in a regular square steel plate is installed and is formed with plural inserting grooves(29). A spreading plate body is made up to be spread by fitting a resistance plate(25) on both plain plate parts of each inserting groove. Then the board body is installed in the ground with the spreading plate body in a state of fixing the lintel rod on the board. Thereby, both side resistance plates of the spreading plate body are spread along both side guide lines.
