FRAME PROVIDING INDUCED CRACK LINE TO DIAGONAL TENSION CRACK AND CONSTRUCITON METHOD OF CONCRETE STRUCTURE USING THE SAME

摘要

The present invention relates to an opening portion frame providing an induced crack line to a diagonal tension crack. According to an embodiment, the frame comprises: a frame body formed in the shape of a closed frame by coupling at least one unit framework to form an opening portion in a concrete wall; and a pipe member installed in each edge area of the frame body to be coupled in the unit framework. According to the embodiment, when a diagonal tension crack occurs in a concrete structure, a proceeding direction of the diagonal tension crack can be induced by a pipe installed in each edge of the frame to minimize an occurrence range of the diagonal tension crack.
