STRUCTURE OF DYWIDAG BOLT WITH L-SHAPED OR C-SHAPED FOLDED HEAD

摘要

PURPOSE: A structure of a dywidag bolt is provided to have excellent tensile force by preventing the separation from the ground by folding the head of a dywidag bolt in the L-shape or the C-shape and to fix a horizontal support of a butt wall support from both sides using a C-shaped dywidag bolt. CONSTITUTION: The dywidag bolt(100) is installed to fix a butt wall support which is installed to support the horizontal pressure of a form and composed of: a male screw part(120) inclined upward at the appointed angle, fitted to the lower part of the butt wall support and fastened by a wing nut plate; and a head part(110) unified with a male screw part(120), buried under the horizontal plane of the ground and folded in appointed times.
