Tension member construction device and tension member construction method of anchor system introducing tension force and chucking pressure plate of tension member construction device of anchor system to introduce tension and its manufacturing method

摘要

A tension member construction apparatus of an anchor system for introducing a tension force is disclosed. The tension member construction device of the anchor system for introducing the tension of the present invention includes a plurality of tension members having one end inserted into the tension member insertion groove of the front wall of the cut excavation method surface and fixed at the end, and a plurality of tension members so that the plurality of tension members can individually penetrate. A support block provided with a tension member through-hole and capable of contacting and supporting the front wall supporting the cut excavation surface, and a plurality of chucking parts press-fitted into the plurality of tension member through-holes, respectively, capable of chucking a plurality of tension members. A construction apparatus, comprising: a tension member tensioning part configured to be penetrated by the plurality of tension members and separated from the tension members, and provided to tension and maintain the tensioned state of the plurality of tension members; and the plurality of tension members are provided so that the plurality of tension members can pass therethrough between the support block and the tension member tension part, and are separable with respect to the support block and the tension member so as to press-fit and fix the plurality of chucking parts into the tension member through-holes, It is possible to directly contact the head of the chucking part, but it is characterized in that it comprises a press-fitting fixing part having a chucking head contact part made of a material having a relatively low hardness compared to the chucking part. According to the present invention, the chucking pressure plate has a material having a relatively low hardness compared to the chucking part and implements a part contactable with the head of the chucking part, so that the head of the plurality of chucking pieces of the chucking part is not arranged neatly. It is possible to prevent the head portion of the chucking piece from being damaged even when a tensile force is applied thereto, thereby preventing a defect in clamping the tensile member to which the chucking portion is finally tensioned.
