Abstract
The utility model belongs to the technical field of steel truss hoisting, and particularly relates to a hoisting device of an asymmetric variable cross-section special-curve extra heavy type large-span steel truss. Accordingly, the hoisting problem of the asymmetric variable cross-section special-curve extra heavy type large-span steel truss is solved. The hoisting device comprises a chain block, a steel wire rope, a crane and a roof jack. The suspension center of the cane is connected with the steel wire rope and one end of the chain block adjustable in length, the chain block and the other end of the steel wire rope are connected with the steel truss respectively, and the roof jack is vertically arranged on the lower portion of the inner end of the steel truss when the steel truss is in an overhead work posture. The hoisting device has the advantages that the hoisting method is simple, practical, low in price, convenient to implement, and safe, and all components used for hoisting can be used repeatedly.
Description
Technical field
The utility model belongs to the technical field of steel truss lifting, is specifically related to the different curve extra-heavy duty type of a kind of asymmetric variable cross-section large span steel truss hanging apparatus.
Background technology
For the lifting of the different curve extra-heavy duty type of asymmetric variable cross-section large span steel truss, in prior art, also there is no ready-made method, and use the hanging method of conventional steel truss, complex steps, construction cost is very high, and poor stability.
Summary of the invention
The utility model, for the solution lifting problem of the different curve extra-heavy duty type of variable cross-section large span steel truss by no means, provides the different curve extra-heavy duty type of a kind of asymmetric variable cross-section large span steel truss hanging apparatus.
The utility model adopts following technical scheme to realize:
The different curve extra-heavy duty type of asymmetric variable cross-section large span steel truss hanging apparatus, comprise jack, wire rope, crane and roof jack, one end of the suspension centre connecting steel wire ropes of crane and the jack of adjustable in length, the other end of jack and wire rope is connected to steel truss, and roof jack is vertically arranged at the inner below of steel truss when overhead work attitude.
The utlity model has following beneficial effect: hanging method is easy, applicable, cheap, convenient, each assembly of safety, lifting use can be recycled.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
In figure: 1-jack, 2-wire rope, 3-crane, 4-roof jack, 5-steel truss, 6-steel core concrete column.
The specific embodiment
By reference to the accompanying drawings the specific embodiment of the present utility model is described further.
The different curve extra-heavy duty type of asymmetric variable cross-section large span steel truss hanging apparatus, comprise jack 1, wire rope 2, crane 3 and roof jack 4, one end of the suspension centre connecting steel wire ropes 2 of crane 3 and the jack 1 of adjustable in length, the other end of wire rope 2 and jack 1 is connected to steel truss 5, and roof jack 4 is vertically arranged at the inner below of steel truss 5 when overhead work attitude.
The different curve extra-heavy duty type of the asymmetric variable cross-section large span steel truss hanging method that adopts the utility model to complete, step is as follows: the geometric position according to steel truss when the overhead work attitude, determine crane hoisting point position, the tie point position of jack and wire rope and steel truss, primary Calculation jack and rope capacity, jack and wire rope are connected to steel truss, then hoisting steel truss built on stilts just slowly, adjust jack length, make the attitude of steel truss when overhead work, slowly hang again higher than steel truss work design height 0.3m, before crane or backward move, locus while then falling work, the outer end of steel truss is connected in place and places restrictions on steel card with steel column concrete column, the inner lifting void of steel truss is placed on roof jack, the gross weight of whole steel truss is still born by crane, with roof jack link be that non-stress can welded condition.
Various utensil used in the present invention is common instrument, combination during use, installation and removal are convenient, according to designing requirement, assemble, just formed the different curve extra-heavy duty type of asymmetric variable cross-section large span steel truss Lift-on/Lift-off System, applicable to the lifting of various special type steel trusss, can coordinate from different cranes, the available former rope that stays, for the hanging method of special type steel truss research.
