Background technology
Along with the high speed development of China's economy and Transportation Infrastructure Construction, increasing public rail and combined longspan steel truss girder CONSTRUCTION OF CABLE-STAYED BRIDGE engineering have appearred.Combined bridge generally adopts steel purlin Cable-stayed Bridge Scheme, and girder adopts biplate purlin formula structure.Two main truss horizontal spacings are larger, the bridge pier side bracket reaches the whole working platform of transposition in length and breadth as the platform for lining that pier pushes up four internode steel girder erections, be also the main support structure that first pair of suspension cable hangs front girder steel weight, pier-side bracket is comprised of two, north and south carriage, load-bearing steel case beam (slipway beam), bearing beam (slide) and three direction displacement adjusting device etc.The carriage column design adopts the steel pipe post structure, suitable bridge is to adopting four comb stakes (one-sided two rows), cross-bridges is arranged two comb stakes, press laterally great slope along bridge to the outermost steel pipe, suitable bridge steel pipe is to the inside pressed minor grade laterally, adopt steel pipe as connecting system, built-in fitting welding on coxopodite column and tower seat between column.Owing to using steel pipe post as carriage, between steel pipe, connected mode has welding or flange to connect, and is welded to connect and causes the overhead welding workload large, and dangerous high, the engineering time is long; And flange connects, and due to more to connecting bolt, sections is more, causes overhead connection that difficulty is installed, and construction risk is large, and the engineering time is long.
Summary of the invention
The present invention is mainly for the existing above-mentioned technical problem of prior art, and the combination H shaped steel pillar bracket of a kind of easy construction, safety is provided.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of combination H shaped steel pillar bracket, comprise the king-tower post, both sides, described king-tower column bottom are respectively equipped with two bases, the oblique outer combination H shaped steel column that is installed with respectively on described four bases, every two described combination H shaped steel columns are symmetrical with respect to the king-tower post; The top of described each combination H shaped steel column is connected with an end of a slipway beam respectively, and the other end of described slipway beam is positioned on the tower pier bearing that is positioned at king-tower post middle part.
As preferably, be connected by many connecting rods between described combination H shaped steel column and king-tower post.
As preferably, between the H shaped steel of described combination H shaped steel column inside by the universal rod body bolt.
As preferably, position connection by end plate by bolt between described combination H shaped steel column sections.
As preferably, described tower pier bearing two ends respectively are provided with a tower pier shearing resistance bearing, and described two slipway beam one ends are hinged with a combination H shaped steel column top respectively, and the other end is positioned on tower pier shearing resistance bearing and draws mutually connection by reinforcing bar.
As preferably, described slipway beam be placed on tower pier shearing resistance bearing an end by the inner preformed hole of described tower pier bearing to drawing finish rolling deformed bar to connect.
As preferably, described every two connect by steel pipe between the combination H shaped steel column of king-tower post the same side.
The present invention makes up H shaped steel bottom joint of vertical column and is fixed on base, other sections connects by end plate place bolt, slipway beam one end is articulated and connected with combination H shaped steel column, one end is placed on tower pier bearing, and by the slipway beam of pull-up structure with tower pier bearing both sides carried out drawing, adopt connecting rod to connect between combination H shaped steel column and king-tower post, connect by steel pipe between combination H shaped steel column, to strengthen stability.At direction across bridge, two H shaped steel braces are connected into integral body, jointly stressed.Supporting capacity of the present invention is large, installs easily, and convenient disassembly has reduced the high-altitude splicing that steel pipe brings difficulty is installed, and construction quality more easily guarantees, has reduced the engineering time, has reduced work high above the ground dangerous, and is conveniently economical.
