Abstract
The invention relates to bridge starting section beam pier side support construction equipment, in particular to a steel truss grider cable stayed bridge starting section beam pier side combined H-shaped steel column bracket which is convenient to construct and safe. The combined H-shaped steel column bracket comprises a main pylon. Two bases are arranged on each of two sides of the bottom of the main pylon, four bases are respectively and fixedly provided with a combined H-shaped steel column outwards in an inclined mode, and every two combined H-shaped steel columns are symmetrical relative to the main pylon. The top of each combined H-shaped steel column is connected with one end of a slide beam, and the other end of the slide beam is arranged on a tower foundation support in the middle of the main pylon. The combined H-shaped steel column bracket is large in bearing capacity, easy to install, convenient to dismantle, economical and convenient, construction time is shortened, and high-altitude work danger is reduced.
Description
Technical field
The present invention relates to bridge initial beam sections pier collateral branch frame construction equipment, the initial beam sections pier of the steel truss girder cable-stayed bridge other combination H profile steel pillar bracket of a kind of easy construction specifically, safety.
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 are there is.The main bridge of non-major P.E.subject generally adopts steel purlin Cable-stayed Bridge Scheme, and girder adopts biplate purlin formula structure.Two panels main truss horizontal spacing is larger, bridge pier side bracket is as the platform for lining of pier top four internode steel girder erection and transposition is whole in length and breadth workbench, also be the main support structure that first pair of suspension cable hangs front girder steel weight, pier-side bracket is made up of two, north and south bracket, load-bearing steel box-girder (slipway beam), bearing beam (slide) and three direction displacement adjusting device etc.Bracket column design adopts steel pipe post structure, along bridge to the stake of employing four comb (one-sided two rows), cross-bridges arranges two comb stakes, great slope is pressed laterally to outermost steel pipe along bridge, minor grade pressed laterally by suitable bridge to the inside steel pipe, adopt steel pipe as connection system between column, coxopodite column welds with built-in fitting on tower seat.Due to steel pipe post as bracket, between steel pipe, connected mode has welding or ring flange to connect, and is welded to connect and causes overhead welding workload large, and dangerous high, the engineering time is long; And ring flange connects, due to more to connecting bolt, sections is more, and cause overhead connection to install difficulty, construction risk is large, and the engineering time is long.
Summary of the invention
The present invention, mainly for the above-mentioned technical problem existing for prior art, provides the combination H profile steel pillar bracket of a kind of easy construction, safety.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: a kind of combination H profile steel pillar bracket, comprise king-tower post, both sides, described king-tower column bottom are respectively equipped with two bases, obliquely respectively on described four bases outer be installed with a combination H profile steel column, the combination H profile steel column described in every two is relative to king-tower column symmetry; The top of described each combination H profile steel column is connected with one end of a slipway beam respectively, and the other end of described slipway beam is positioned on the tower pier bearing that is positioned in the middle part of king-tower post.
As preferably, described combination H profile steel column is connected by many connecting rods with between king-tower post.
As preferably, by universal rod body bolt between the H profile steel of described combination H profile steel column inside.
As preferably, between described combination H profile steel column sections, position connection by end plate by bolt.
As preferably, described tower pier bearing two ends are respectively provided with a tower pier shearing resistance bearing, and described two slipway beam one end combine H profile steel column top respectively with one hinged, and the other end to be positioned on tower pier shearing resistance bearing and to draw connection mutually by reinforcing bar.
As preferably, described slipway beam be placed in one end on tower pier shearing resistance bearing by described tower pier bearing internal reservation hole to drawing finish rolling deformed bar to connect.
As preferably, described every two are passed through fastener for connection between the combination H profile steel column of king-tower post the same side.
The present invention combines H profile steel bottom joint of vertical column and is fixed on base, other sections is connected by end plate place bolt, slipway beam one end is articulated and connected with combination H profile steel column, one end is placed on tower pier bearing, and by the slipway beam of tower pier bearing both sides being carried out drawing to pull-up structure, between combination H profile steel column and king-tower post, connecting rod is adopted to connect, by fastener for connection between combination H profile steel column, to strengthen stability.At direction across bridge, two H profile steel braces are connected into entirety, jointly stressed.Bearing capacity of the present invention is large, installs easily, convenient disassembly, decrease the high-altitude splicing installation difficulty that steel pipe brings, and construction quality more easily ensures, decreases the engineering time, reduces work high above the ground danger, economical convenient.
