MULTI-STIFFENER FOR CIVIL ENGINEERING AND CONSTRUCTION WORK

摘要

The present invention relates to a multi-stiffener for a civil engineering and construction work. The present invention is to provide the multi-stiffener for a civil engineering and construction work, which is easily installed and dismantled and can be reused. The multi-stiffener for a civil engineering and construction work can simply control the length thereof and has high economical feasibility. To achieve the purpose of the present invention, the multi-stiffener for a civil engineering and construction work includes: an outer pipe member (11) having a male screw (11c) for height control around a guide hole (11b), wherein a pair of the guide holes (11b) is formed to be symmetric in a longitudinal direction from a position separated from a blocked end at fixed intervals; an inner pipe member (12) having an end formed in the shape of a blocked pipe and having multiple through holes (12a) formed to be symmetric at predetermined intervals from the open end, wherein a blocked part is inserted into a penetration hole (11a) of the outer pipe member (11) and moves in the longitudinal direction; an outer pipe support plate (13) integrally formed at the open end of the outer pipe member (11); an inner pipe support plate (14) integrally formed at the open end of the inner pipe member (12); an inner pipe position control pin (15) installed to penetrate both of the guide hole (11b) of the outer pipe member (11) and the through hole (12a) of the inner pipe member (12); and a position determining unit (16) coupled to the outer pipe member (11) by having a female screw coupled to the male screw (11c) for the height control of the outer pipe member (11) on the inner side and changing the position of the inner pipe position control pin (15) by rotating.;COPYRIGHT KIPO 2017
