Patent number: 8910336Abstract: An upper structure for a bridge includes a coping placed on the top end of a pier, and a girder held by the coping, wherein a side surface of the coping and an end surface of the girder are configured as inclined surfaces (or vertical surfaces), wherein a shear key protrudes on one of the inclined surfaces (or vertical surfaces), and a shear key slot is formed in another one of the inclined surfaces (or vertical surfaces) so as to be engaged with the shear key. The present disclosure can reduce the construction cost, can realize improved structural efficiency of the bridge upper structure, can realize an easy installation of the girders, can easily combine the girders with the coping without plastering or fixing with mortar by site work, and can efficiently resist to a shear stress that may be generated in the bridge.Type: GrantFiled: September 29, 2011Date of Patent: December 16, 2014Assignee: Supportec Co., Ltd.Inventor: Man-Yop Han

Patent number: 8689383Abstract: An upper structure for a bridge includes a coping placed on the top of a pier, and girders held by the coping, wherein the coping has girder holding grooves. The girders are installed continuously without using bridge bearings. The coping and the girders behave in an integrated state. The girders are held by being fitted into the grooves, so the coping is not excessively exposed to the outside. The girders and the coping are dry joined together in a prestressed state using prestressed steel strands. Further, the girders and the coping can be integrated with each other without being processed by site work.Type: GrantFiled: September 29, 2011Date of Patent: April 8, 2014Assignee: Supportec Co., Ltd.Inventor: Man-Yop Han

Publication number: 20130263392Abstract: An upper structure for a bridge includes a coping placed on the top of a pier, and girders held by the coping, wherein the coping has girder holding grooves. The girders are installed continuously without using bridge bearings, thereby reducing the construction cost. The coping and the girders behave in an integrated state, thereby realizing improved structural efficiency. The girders are held by being fitted into the grooves, so the coping is not excessively exposed to the outside, thereby realizing a good appearance of the bridge. The girders and the coping are thy-joined together in a prestressed state using prestressed steel strands, so that the strength of the girders and the resistance to a negative bending moment can be increased. Further, the girders and the coping can be integrated with each other without being processed by site work, thereby realizing improved structural efficiency and reducing the construction period.Type: ApplicationFiled: September 29, 2011Publication date: October 10, 2013Applicant: SUPPORTEC CO., LTD.Inventor: Man-Yop Han

Patent number: 8539629Abstract: The present invention relates to a fit-together type of precast concrete lining and bridging structural body in which main girders are integrated with deck plates. Precast concrete deck members connected in longitudinal and transverse directions are pre-stressed by pre-stressed members, thereby making it possible to increase load carrying capacity or rigidity of a structure to stably use the structure for a long time. Further, it is possible to support the load applied from the top of a deck structure with a small thickness, and to make the deck structure light. Due to a knockdown type (fit-together type), installation and dismantlement are easy, and reuse is possible, and thus it is possible to provide convenient construction and low production costs.Type: GrantFiled: February 18, 2009Date of Patent: September 24, 2013Assignee: Supportec Co., Ltd.Inventor: Manyop Han

Publication number: 20100319280Abstract: The present invention relates to a precast temporary facility structure composed of segment members which is manufactured in a predetermined shape in advance at a factory and disposed close to the inner side of a temporary facility wall by fixing means and filled with concrete, and connectors integrally connected to the ends of the segment structures by coupling means to connect the segment members. Accordingly, it is possible to achieve sufficient support force for a long span temporary facility wall having a large entire length and reduce time for curing concrete by the precast, such that it is possible to reduce the construction period.Type: ApplicationFiled: January 30, 2009Publication date: December 23, 2010Applicant: SUPPORTEC CO., LTD.Inventor: Manyop Han
