Abstract
A hoisting tool for a hollow slab beam comprises an upper crossbeam, a lower crossbeam and steel bars with threads at the two ends thereof. The upper crossbeam consists of at least two even-numbered back-to-back channel steel bars, two coating steel plates and at least one stiffening steel plate, the two coating steel plates are welded at the two ends of the upper crossbeam channel steel bars, and the at least one stiffening steel plate is welded between the two upper crossbeam channel steel bars; and the lower crossbeam consists of a rectangular steel plate, two trapezoidal steel plates and a plurality of channel steel bars, holes with a diameter 1-2 mm larger than that of the steel bars with threads at the two ends thereof are formed on the lower crossbeam steel plate, and the distance between the two upper crossbeam channel steel bars is the same as the diameter of the holes formed on the lower crossbeam.
Description
Technical field
The utility model relates to a kind of bridge construction special tool, particularly relates to a kind of lifting device of hollow slab girder.
Background technology
Remove in the lifting construction process at hollow slab girder, because the original design suspension ring all cut off in the bridge floor construction, and the beam gap between the plate-girder are especially little, the lifting steel rope is difficult to penetrate, and angle of embrace is installed difficulty at the bottom of the beam; Every lifting one Pin beam all needs beam seam strutted with equipment and could make things convenient for penetrating of steel rope, and not only production time is long, and potential safety hazard is big, also will increase the operating technique cost.
In addition, in hoisting process, because steel rope is through fixing, thus be easy to and can the fracture of wire phenomenon occur because of wearing and tearing and stressed concentrating, so practical life is short, poor stability.
Moreover, reeve repeatedly, the construction operation time is long, efficient is low.
Summary of the invention
In order to address the above problem, the purpose of the utility model suspender be to provide a kind of simple in structure, flexible operation is easy, lifting efficient height and the good lifting device of safety performance.
For achieving the above object, the hollow slab girder lifting device that the utility model provides, the reinforcing bar that comprises upper and lower crossbeam and both end thread (BET), described entablatrance is made up of the dos-channel-section steel and the encased steel plate of two even numbers and the steel plate of putting more energy at least, described encased steel plate is two block plates that are welded on described entablatrance channel-section steel two ends, and the described steel plate of putting more energy into is at least one block plate that is welded between described two groups of entablatrance channel-section steels; Described cross sill is welded to form by a rectangular steel plates, two blocks of trapezoidal steel plates and Duo Gen channel-section steel, perforate on the described cross sill steel plate, described opening diameter is than the big 1-2mm of bar diameter of described both end thread (BET), spacing is identical with described cross sill opening diameter between two groups of channel-section steels of described entablatrance, the reinforcing bar lower end of two both end thread (BET)s penetrates the cross sill perforate earlier, lower nuts tightens, the reinforcing bar upper end of two both end thread (BET)s penetrates between the entablatrance channel-section steel, the locking upper nut is fixed on suspender on the hollow slab girder body.
For conveniently hanging the lifting steel rope, can be between entablatrance and space plate-girder chock side, but with adjust at the bottom of the entablatrance and height crossbeam between the back at the bottom of thick round steel of horizontal welding to prevent the steel rope slippage.
Described lower and upper cross-member size and fining twisted steel specification are relevant with the weight of beam body.
The box girder lifting device that the utility model provides is to utilize upper and lower crossbeam as load carrier, utilize the high-strength resistance to tension of threaded deformed bar simultaneously, lower and upper cross-member is connected into integral body, not only can increase compression area and stability at the bottom of the beam like this, and can save the wearing and tearing of steel rope and concentrate stressed problem, therefore can prolong practical life and safety is good.The easy accessibility of steel rope overlaps suspender more and uses simultaneously in addition, can improve lifting efficient, reduces construction cost thereby shorten the engineering time.

Concrete enforcement side
Be elaborated below in conjunction with accompanying drawing and the concrete suspender of implementing the utility model is provided.
As Fig. 1, Fig. 2, shown in Figure 3, the hollow slab girder lifting device that the utility model provides, comprise the reinforcing bar 4 of entablatrance 3, cross sill 5, both end thread (BET), a plurality of nut 1, four pads 2, two steel ropes 8 and two blocks of lumps of wood 6, entablatrance 3 is made up of the dos-channel-section steel 9 of two even numbers and encased steel plate 10 and the centre steel plate 11 of putting more energy at least, encased steel plate 10 is welded on the two ends of entablatrance channel-section steel 9, and the steel plate 11 of putting more energy into is welded between two groups of entablatrance channel-section steels 9; Cross sill 5 is welded to form by a rectangular steel plates 15, two blocks of trapezoidal steel plates 13 and Duo Gen channel-section steel 12, perforate 14 on the cross sill steel plate 15, perforate 14 diameters are than the big 1-2mm of diameter of the reinforcing bar 4 of both end thread (BET), and spacing is identical with the diameter dimension of cross sill perforate 14 between entablatrance two channel-section steels 9.
The specification of the quantity of described lower and upper cross-member channel-section steel 9 and sectional dimension and threaded reinforcing bar 4 adjusts accordingly with hollow slab girder 7 weight, to satisfy needed bending resistance of lifting and resistance to shear.
When carrying out the lifting of beam body, at first the lower end of the reinforcing bar 4 of both end thread (BET) is penetrated earlier in the perforate 14 on the rectangular steel plates 15, lower nuts tightens, make the bottom of the end face of cross sill 5 and hollow slab girder 7 closely connected as far as possible, entablatrance 3 lifts the upper end of threaded reinforcing bar 4 is penetrated, the locking upper nut is fixed on suspender on the hollow slab girder body 7.Two steel ropes 8 are hung on the two ends of entablatrance 3 respectively, utilize original lifting appliance to get final product according to the method for operation of routine at last.
