Description
Technical field
The utility model relates to a kind of bridge construction lifting dress system, particularly a kind of mast-up of prefabricated case beam.
Background technology
At present, along with the develop rapidly of China's passenger dedicated railway line and inter-city rail transit engineering construction.In order to guarantee the high ride of track engineering lasting stability, the construction standard of passenger dedicated railway line is more and more higher, construction technical requirement is more and more newer, the construction quality management is more and more tighter.Elevated bridge is as the primary structure thing of Line for Passenger Transportation and inter-city rail transit engineering, the prefabricated quality of bridge is the key of passenger dedicated railway line and inter-city rail transit engineering construction, and the bridge reinforcement engineering is as the pass key control operation of bridge prefabrication, and the built-in fitting of bridge, prestress pipe location etc. is all finished in reinforced bar engineering.Guarantee that moderate finite deformation does not take place for cage of reinforcement, built-in fitting and prestress pipe coordinate in the process of reinforcing bar lifting, this is the key of reinforced bar engineering quality control on construction.Present prefabricated construction to the case beam, be after the reinforcing bar canopy carries out the processing of cage of reinforcement, to lift, the operation of after lifting is finished internal mold, colligation gluten, installation end mould being installed again, this job practices makes cage of reinforcement deform easily, and working procedure is many, and the cross-operation link is many, the work efficiency of construction is not high, construction quality can not be controlled effectively, increase equipment and artificial input, wasting manpower and material resources.
The utility model content
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, provide a kind of working procedure few, simple to operate easily, safe and convenient can be gone into prefabricated case beam beam body reinforcing bar and internal mold integral hoisting the integral hoisting frame of mould.
The technical solution adopted in the utility model is as follows:
Integral hoisting frame of the present utility model, comprise main couple, jack truss, vertical connecting rod, diagonal member, suspension hook, it is characterized in that: described main couple comprises row, arranges the i shaped steel that parallel longitudinal distributes down, row or following row include at least 2 I shapes on the described main couple, be horizontally connected with top rail on the i shaped steel of arranging on the described main couple, connect by diagonal member, vertical connecting rod between the i shaped steel that described main couple is arranged up and down; Described jack truss comprises that 2 i shaped steels are distributed under the main couple row's both sides, and by lower transverse beam and main couple down row's i shaped steel be connected, be connected by the i shaped steel of arranging both sides on brace and the main couple; Described main couple row's i shaped steel, jack truss, lower transverse beam down is connected with wire rope, and described suspension hook is connected on the wire rope.
Because main couple adopts 4 and above i shaped steel to present row, arrange the parallel longitudinal distribution down, be connected to become stable triangular structure by vertical connecting rod, diagonal member, i shaped steel, make that main couple is the core part of the force of a stable frame construction frame as whole integral hoisting frame, owing to adopt i shaped steel, its carrying capacity that can bear is bigger, feasible construction is more safe, so can bear the needs of large-tonnage case beam lifting.Be positioned at the main couple both sides with two i shaped steels as jack truss, mainly be in order to satisfy the needs of the big facet off-centre of some box girder bodies, because the big facet off-centre of beam body causes beam body center of gravity line not overlap with beam body center line, certainly will make that like this center of main couple and mast-up is inconsistent, add the both sides of jack truss at main couple, can so that the center of gravity of beam body still in the scope of main couple; And add the both sides of jack truss at main couple, can make mast-up can lift the case beam steel structure of bigger cross-sectional area.Suspension hook makes on following row in main couple, jack truss, the lower transverse beam, mainly is in order to make in hoisting process, and the stress point of case beam evenly and disperse more helps the protection of beam body reinforcing bar, internal mold, end mould, avoids causing distortion because of stressed concentrating.
Described main couple is connected by suspension ring between row's i shaped steel, jack truss, lower transverse beam and the wire rope down.
Because row's i shaped steel, jack truss, lower transverse beam are connected down with main couple by suspension ring between the wire rope, make wire rope adjustable in suspension ring, when using, can be according to beam body and internal mold, adjust its length of steel wire rope, thereby make the integral hoisting frame be suitable for the different beam body of multiple structure.
In sum, owing to adopted technique scheme, the beneficial effects of the utility model are:
1. the integral hoisting frame carries out integral hoisting to beam body reinforcing bar, internal mold, end mould, has reduced the working procedure of case beam hoisting process;
2. the integral hoisting frame carries out the monolithic lifting to beam body reinforcing bar, internal mold, end mould, has reduced the distortion of beam body skeleton and internal mold thereof, makes the case beam more can satisfy the needs of construction works.
3. what the main couple of integral hoisting frame adopted is tower structure, makes the mast-up Stability Analysis of Structures, safe and convenient.
4. mast-up is to the integral hoisting of case beam, makes that multinomial operation can parallel operations, accelerated construction speed, and it is consuming time to have reduced engineering, has saved cost.
