Apparatus for reinforcing slab installing the upper and lower cover plate and fixing device of tension materials in prelexed H-type beam

摘要

The invented method slab bridges, and as to apply to the slab or beam of the concrete slab using Preflex installing the upper and lower cover plates and the tendons anchoring devices in the H-shaped beam slab reinforcement devices, and this reinforced construction in order to improve aging or load-bearing capacity relates to, give soteum the H-shaped beam with a predetermined interval, the stomach and welding installation of vertical reinforcement, and is installed available the upper cover plate contact the top plate, the bottom plate is, install the lower cover plate, both ends of the H-shaped beam in contact available for the lower cover plate, the central portion by putting again prestressed after the go bit attached in a high-strength bolt making the tack welds and go root joint part completely welded and high strength bolts joining a slab reinforcement H-type beam in a bridge when installing the slab reinforcement beam H By using a steel bar after installing the pier supporting device can be hit by a pier both sides and connected to each other, alternately, the abutment support device by the use of the anchor bolt in the wall of the alternate shift the support device to form the slab reinforcement H after a fixed installation through the beam and the slab and integral with the pier or abutment support device and the slab after the reinforcing height adjustment between the H-shaped beam the slab reinforcement to install and H hyeongbim one closely with the lower surface of the slab, the anchor bolt or epoxy etc. a one after the tensile force to the anti-corrosive treatment, and a reinforcing or improving the load bearing capacity of the slab, and the tendons to form a slab reinforcement H beam at a later time to form the slab reinforcement when it is necessary to increase the reinforcing or supporting load of the bridge H beam such that tendons to the fixing device for the introduction of fixing the tendons after installation on both sides by using a tension tendons yuapjaek tensile force By introducing or install the radiator at the center DB tendons fixing device is installed on the opposite sides to introduce a tensile force.; In addition, the slab bridge or top of the held in place by a retaining nut after penetration, and the through rod anchor penetrates the slab of the through rod anchors that pass through the entire thickness of the slabs and beams of concrete structures on both side portions of the type slab reinforcement H beam to held in place by a retaining nut and filled sealing with epoxy etc. to prevent corrosion, for a slab bridge slab above a drilling drilling the asphalt formed there and filled with epoxy, the slab reinforcement H-shaped beam to the slab or beam bottom and the anchor after such that the integral with a bolt or epoxy an anti-corrosive treatment, and for the introduction of tensile force at the time of slab reinforcement H-shaped beams it is necessary to increase the reinforcing or supporting the load of the slab or beam and tendons to form the next slab reinforcement H beam by installing the tendons on both sides of the fixing device and fixing the tendons introducing a tensile force by the tension tendons yuapjaek After, or by installing a radiator at the center DB tendons fixing device is installed on both sides of a through the tendons to introduce a tensile force by the tension tendons yuapjaek.; Installation As a further example, to a slab or the increase of the reinforcing and supporting the load of the beam in the concrete to give soteum to form the H-beam with a predetermined interval, the stomach and Welding the sujikjae, in contact with soluble the upper cover plate top plate and the lower plate has, install the lower cover plate to the opposite ends is in contact available for the lower cover plate, the tack welds and the joint after the central portion is added to re-prestressed hanhue to the bond to the high-strength bolt portion of the H-shaped beam completely welded and after the bolts joining the slab reinforcement H beam produced by a fixedly installed by a supporting device for an anchor bolt can be mounted to the slab reinforcement H-shaped beams on each side wall which supports the slab or beam of the concrete slab reinforced H-type through the beam and the support device and parts of the height adjustment between the slab reinforcement beam H Install the slab reinforcement H hyeongbim of after using the anchor bolt or epoxy etc. After closely with the lower surface of the slab so that the slab and the integration of the anti-corrosive treatment, and the tendon for further type slab reinforcement H beam slab or beam after the tendons fixing device for introducing a tensile force at the time of slab reinforcement H-shaped beams it is necessary to increase the reinforcing or supporting a load by installing the slab reinforcement device provided on both sides to fix the tendons introducing a tensile force by the tendons tension yuapjaek or by installing the radiator at the center DB tendons fixing device is installed on both sides of the tensile force is introduced.
