The universal lifting appliance is characterized by comprising a lifting beam, two longitudinal beams, two traverse connecting beams, four limiting baffle blocks and a lifting lug, wherein the two longitudinal beams are parallel with each other to be vertically connected with the lifting beam; the inner sides of the two longitudinal beams are fixed with the two traverse connecting beams in parallel; two sides of the two longitudinal beams are provided with two limiting baffle blocks; the lifting lug is fixed in the middle of the lifting beam; the lifting beam, the two longitudinal beams, the two traverse connecting beams and the four limiting baffle blocks are made from the profile steel and the plate; and the profile steel and the plate are welded into a frame structure to form into a whole body. The utility model provides the universal lifting appliance which is not affected by the hydrological and climatic conditions, simple and universal for the variable span precast beam.
Description
Technical field
The utility model relates to a kind of precast beam lifting construction technical field, particularly becomes the general suspender of span precast beam lifting construction technology, is exactly to become the general suspender of span precast beam.
Background technology
China's speedway is medium and small strides footpath bridge, interchange viaduct and strides the engineering quantity of river Oversea bridge access bridge etc. very big, influenced by design and execution conditions, and difference is striden the precast beam of footpath combination as main bridge superstructure form, obtains application very widely.
The construction traditional method of such superstructure has at present: 1, adopt large-scale lifting appliance to lift in conjunction with the special hanger monoblock.The lifting of land fabrication beam is limited by crane gear and field condition, and precast beam weight is generally less; The monoblock lifting needs large-scale floating crane equipment in the water, is subjected to hydrology weather influence bigger.2, adopt the precast beam mounting technique that hang purlin, gantry and the bridge formation machine combines.After precast beam is transported to the bridge location place, adopts purlin, gantry to hang the whole feeding bridge formation machine that promotes and install piecewise, purlin, gantry is hung and is promoted difference and stride the footpath precast beam and need special hanger.
Summary of the invention
The purpose of the present utility model provides a kind of hydrology weather influence, simple and easy, general general suspender of change span precast beam of not being subjected to.
The purpose of the present utility model is to realize like this, become the general suspender of span precast beam, it is characterized in that: general suspender comprises lifting beam, longeron, transverse strut, positive stop and hanger, two longerons are parallel to be connected with lifting beam is vertical, two transverse struts of two inboard secured in parallel of longeron, there are two positive stops two longeron both sides, the lifting beam center fixed has hanger, a lifting beam, two longerons, two transverse struts and four positive stops are shaped steel and sheet material, and shaped steel and sheet material are welded into frame structure and constitute an integral body.
Described four positive stops are the crotch structure.
Positive stop chucking precast beam two ends in the described general suspender, the longeron of general suspender and precast beam one end are fixing by the wire rope binding, and the hanger of general suspender is connected with purlin, gantry suspension hook, and precast beam is promoted.
The utility model has the advantages that: general suspender is welded by shaped steel such as lifting beam, longeron, transverse strut, positive stop and hanger and sheet material.In the precast beam end general suspender is installed, with wire rope general suspender is connected with precast beam, hook is hung in general suspender and purlin, gantry link together, precast beam is installed in lifting.Difference is striden footpath precast beam lifting and is selected corresponding wire rope perforation and twine point.In the design, purlin, gantry is hung and is satisfied the lifting of largest span precast beam, and other less footpath precast beams of striding adopt general suspender lifting in beam end, suspender one end hangs the hook lifting by the purlin, one end props up on the case back, and precast beam is connected with suspender by wire rope, forms the shoulder pole structure.The utility model utilizes the big characteristics of precast beam rigidity, and it is light and handy finally to reach design, saves lot of materials, convenient purpose of installing.

Fig. 5 is the C-C profile of Fig. 2.
Among the figure: 1, precast beam; 2, wire rope; 3, purlin, gantry suspension hook; 4, general suspender; 401, lifting beam; 402, longeron; 403, transverse strut; 404, positive stop; 405, hanger.
The specific embodiment
As Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, general suspender 4 comprises lifting beam 401, longeron 402, transverse strut 403, positive stop 404 and hanger 405, two longerons 402 parallel with 401 vertical connections of lifting beam, two transverse struts 403 of two longeron 402 inboard secured in parallel, there are two positive stops 404 two longeron 402 both sides, lifting beam 401 center fixed have hanger 405, a lifting beam 401, two longerons 402, two transverse struts 403 and four positive stops 404 are shaped steel and sheet material, and shaped steel and sheet material are welded into frame structure and constitute an integral body; Four positive stops 404 are the crotch structure.
During use, positive stop 404 chucking precast beams 1 two ends in two general suspenders 4, the longeron 402 of general suspender 4 is fixing by wire rope 2 bindings with precast beam 1 one ends, and the hanger 405 of general suspender 4 is connected with purlin, gantry suspension hook 3, to precast beam 1 lifting.
In whole precast beam installation process, system considers that general suspender 4 satisfies the integral hoisting requirement that difference is striden the footpath precast beam.Hang by largest span precast beam design lifting purlin, other less footpath precast beams of striding design the construction technique that general suspender lifts.
The suspender process segment: determine the suspender size according to the shortest footpath precast beam of striding, according to the heaviest beam body design suspender intensity, shaped steel such as hanging beam before the suspender 401, longeron 402, transverse strut 403, positive stop 404 and hanger 405 and sheet material are welded into frame structure, and stride the footpath according to the precast beam difference and be provided with that wire rope 2 twines points on the suspender longeron 402.
The prefabricated stage of beam body: according to the suspender design, wire rope 2 perforation are reserved in the beam end appropriate location in the precast beam 1 prefabricated process, and precast beam 1 stress point is protected.
As shown in Figure 1, the precast beam lifting stage: in precast beam 1 end general suspender 4 is installed, with wire rope 2 general suspender 4 is connected with precast beam 1, general suspender 4 is linked together with purlin, gantry suspension hook 3, precast beam is installed in lifting.Difference is striden footpath precast beam lifting and is selected corresponding wire rope perforation and twine point.
