Abstract
The utility model discloses a continuous beam cradle hoisting structure for corrugated steel webs. The structure comprises a cradle body, wherein slide track beams and diagonal draw bars are arranged on the cradle body; lifting devices are glidingly arranged on the slide track beams and adopt electric hoists; and the slide track beams and diagonal draw bars are fixed on the cradle body through pin shafts. With the adoption of the continuous beam cradle hoisting structure for the corrugated steel webs, the problem of hoisting the corrugated steel webs during the suspension casting construction can be solved, so that manual labor and equipment investment are saved, and the construction cost is reduced.
Description
Technical field
The utility model relates to a kind of hoisting structure, especially relates to a kind of Wavelike steel webplate continuous beam suspended bracket hoisting structure.
Background technology
The corrugated steel web prestressing combined box beam is the combining structure that is made of concrete roof and floor, external prestressing muscle and corrugated steel web three.The concrete web of traditional PC beam bridge being replaced with the structural steel plate of bellows-shaped, is a kind of of steel and concrete combined structure bridge.Compare with traditional concrete web box girder, the corrugated steel web prestressing combined box beam can alleviate deadweight, improve prestressed efficient and reduce the prestress steel material use quantity, corrugated steel web does not play effect of contraction to upper and lower edge creep of concrete, drying shrinkage deformation, external pre-stress bundle can be replaced, be conducive to maintenance and the reinforcement of bridge, and the bed rearrangement bridge has stronger aesthetic feeling.In addition, can also omit the steps such as configuration, concrete laying of reinforcing bar in the concrete web and PC steel, accelerate speed of application.
But, because the bridge history of the type is relatively short, domestic to such bridge research start late, large span Wavelike steel webplate Continuous Rigid-Frame Bridge construction experiences is less, has difficulties when actual lifting construction, the wasting manpower and material resources increases construction cost.
Summary of the invention
The purpose of this utility model is to provide a kind of Wavelike steel webplate continuous beam suspended bracket hoisting structure, can solve the lifting problem of steel web in the cantilever casting construction process, saves manpower and equipment investment, reduces construction cost.
For achieving the above object, the utility model provides a kind of Wavelike steel webplate continuous beam suspended bracket hoisting structure, comprises the Hanging Basket main body, and described Hanging Basket main body is provided with slipway beam and diagonal member, and sliding on described slipway beam is provided with lifting appliance.
Preferably, described lifting appliance is electric block.
Preferably, described slipway beam and described diagonal member are fixed on described Hanging Basket main body by bearing pin.
Therefore, the utility model adopts the Wavelike steel webplate continuous beam suspended bracket hoisting structure of said structure, can solve the lifting problem of steel web in the cantilever casting construction process, saves manpower and equipment investment, reduces construction cost.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the structural representation of the utility model Wavelike steel webplate continuous beam suspended bracket hoisting structure embodiment.
The specific embodiment
Embodiment
Fig. 1 is the structural representation of the utility model Wavelike steel webplate continuous beam suspended bracket hoisting structure embodiment, as shown in Figure 1, comprises Hanging Basket main body 1, and Hanging Basket main body 1 is provided with slipway beam 2 and diagonal member 3, and sliding on slipway beam 2 is provided with lifting appliance 4.In the present embodiment, lifting appliance 4 is selected electric block.Electric block moves freely on slipway beam 2.Wavelike steel webplate is positioned under Hanging Basket main body main truss, and because Wavelike steel webplate is larger, under Hanging Basket main body main truss, the space is little, adopts crane lifting there is no the operating space, therefore need to design the described hoisting structure of the present embodiment on Hanging Basket.
Be fixed on Hanging Basket main body 1 by bearing pin in the present embodiment.Slipway beam 2, diagonal member 3 connect to form fixing three-legged structure with the Hanging Basket main body.Mentality of designing according to hoisting structure, lifting appliance should be arranged on the Hanging Basket main body, because the design feature of Diamond-Shape Form Traveler self and Hanging Basket main body main truss are positioned at actual conditions directly over Wavelike steel webplate, hoisting machine tool should be arranged on Hanging Basket main body main truss, and can only be below main truss.
The present embodiment checks first before lifting whether electric block works, and the lifting wire rope has or not fracture of wire, burr situation.Check errorless after, the stool type angle bar frame of burn-oning in the bed die termination, total powerstation is emitted the position of Wavelike steel webplate bottom wing listrium on angle bar frame, level gauge is measured the Wavelike steel webplate Bottom Altitude.Four Wavelike steel webplates are had bad luck horizontal positioned under electric block.Then wire rope is penetrated in the perforate of Wavelike steel webplate top flange plate and lock, it is vertical that wire rope penetrates in position assurance Wavelike steel webplate lifting process the steel web.Start electric block and at the uniform velocity promote Wavelike steel webplate to the top.Then electric block moves horizontally to the Hanging Basket main direction along the sliding beam of level, and arrival is slowly transferred Wavelike steel webplate behind the installation site.Simultaneously front end adopts bottle gouard moved by hands to hang on to promote on slipway beam that the Wavelike steel webplate front end is finely tuned or the fine setting of crane hook, guarantee that Wavelike steel webplate first of upper end bolt penetrates in the hole, screw nut, adjust the Wavelike steel webplate elevation to design attitude, all the other bolts are penetrated in the hole tighten.The Wavelike steel webplate lower end is checked by lofting control point, hangs up magnetic line of force pendant in the Wavelike steel webplate termination, checks the Wavelike steel webplate verticality, and laterally guide chain is adjusted Wavelike steel webplate off normal and verticality until meet design requirement, and guarantees the lifting precision of the present embodiment.
Therefore, the utility model adopts the Wavelike steel webplate continuous beam suspended bracket hoisting structure of said structure, can solve the lifting problem of steel web in the cantilever casting construction process, and relatively traditional crane lifting is saved manpower and equipment investment, reduces construction cost.
It should be noted that at last: above embodiment is only in order to the technical solution of the utility model to be described but not be limited, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be modified or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technical scheme break away from the spirit and scope of technical solutions of the utility model.
