摘要
present invention is H-shaped steel bottom flange of the lower casing prestressed concrete poured by the fabricated composite beam Contractors installing it on the ground next to each other after assembly dismissed and the old bridge connecting the upper slab and pour the curing unit to form a prestressed composite beam bridge assembly, and then install it to the pier and the prestressed composite beam bridge abutment on the prestressed composite beam relates to. ; Shear plate installed to form a given inner end cross beam welding the front end surface of the side end portions of the H-shaped steel, and casting the concrete, while the action of the lower casing of the downstream load reflection profile Curing to form the rest Priest composite beams and installed for each unit on the upper flange raise a certain distance inward from both ends of the prestressed composite beam bolt connections installed vertically in the abdomen and then into the inner end of both ends of the prestressed composite beam shear while maintaining the lateral plate installed at regular intervals in resistance welding a plurality of bending moment resistance plate, adjacent to the shear resistance plate provided on the abdomen to the inside of both ends of the prestressed composite beam and bending moment resistance provided by the H-shaped steel plate and In the shear resistance plate and connected to each other and resist bending moments and plate steel H-shaped portion that is connected to each other by synapses install the connection plate into the second and then install the bolts connecting one end cross beam using high-strength bolts and the prestressed Reinforced where you can bolt holes in the upper flange connecting bolts to connect the ground to a certain distance inside the side end portions of the composite beam is attached by installing an impressive support this impression formed a plurality of holes formed in the central portion of the support plate to meet each other, raise the support and the support plate The left side of the abdomen between the stomach and the upper flange reinforcement piece to meet part of the lifting device is installed in an impressive device installed on both sides, while each of at least a plurality installed on the upper ground plan of the hike over each of a plurality of installation and support, Second-hand teeth and bridges installed at the upper assembly to cure a unit of prestressed composite beam bridge, and then pour the slab, making assembly for installation of bridge impression produced by the wire for prestressed impression devices installed on the unit by using a composite beam bridge crane After impressive piers and prestressed composite beam will mount the unit on the bridge to replace the target to complete the installation of prestressed composite beam forming a bridge laid over the asphalt road connecting the assembly after installing railings and bridges the upper slab with each other.
