Description
Technical field
The utility model is related to structural steelwork installation Technology field, more particularly to a kind of I-shaped floor girder steel is hung
Assembling structure.
Background technology
Steel construction has many advantages, such as that light-weight, anti-seismic performance is good, repeatable utilization, shared by recent year construction steel structure
Ratio significantly rises.In various configurations, floor beam is largely using I-shaped floor girder steel, and girder steel quantity is more, hoisting steel beam
Occupy longer construction period and more large-scale tower crane machine-team.
There are two types of traditional hoisting steel beam methods.
The first hanging method：Using two steel cord ends joining shackles, steel wire rope is bundled in girder steel with shackle
At a quarter span, the quadrangle setting flexible material that steel wire rope is contacted with girder steel protects girder steel and steel wire rope；It is adjusted before lifting
Whole shackle and the position of steel wire rope binding point, so that horizontality is presented after steel beam lifting；Shackle is removed after in place and flexibility is protected
Protect substance.There are following defects for this method：If binding is loosely, steel wire rope is likely to situation about having skidded, and causes lifting accident；
If the guarded by location that steel wire rope is contacted with girder steel is bad, the paint and steel wire rope of girder steel will be damaged, cause quality accidents；
When steel wire rope is removed after in place, flexible protective substance freely descends slowly and lightly, and is difficult to collect in upper air installing.The hanging method, which exists, to be hung
Heavy workload is filled, security-hidden trouble is more, and the occupancy loop wheel machine time is longer, and installation progress is slow.
Second of hanging method：Lifting lug is symmetrically welded in girder steel both ends top flange.Although the hanging method is safe and reliable,
Progress is fast, but the transport space of bigger that girder steel occupies after top flange welding lifting lug, conevying efficiency decline；It needs to cut after the completion of lifting
Lifting lug is cut, not only wastes steel, also increase additional human weld and cuts off lifting lug work, and destroy girder steel antifouling paint.
The quantity of girder steel is more in general structural steelwork, and the lifting speed of girder steel directly determines entire structural steelwork
Construction speed, therefore the security-hidden trouble improved in the lifting speed of girder steel, reduction hoisting process is that current urgent need solves
Problem.
Utility model content
Lifting efficiency, safe and reliable I-shaped are effectively improved the technical problem to be solved by the utility model is to provide a kind of
Type floor steel beam lifting structure.
Used technical solution to solve above-mentioned technical problem：A kind of I-shaped floor steel beam lifting structure, including work
Font floor girder steel and special hanger, it is characterised in that：It is set at a quarter span of the I-shaped floor girder steel top flange
There are two the technique hole for hoist in a center of symmetry about top flange central point, the special hanger includes supporting plate and in supporting plate
The shackle plate of upper side is equipped with one piece of reinforcing plate between the supporting plate and shackle plate, the opposite side above the supporting plate
Equipped with the positioning pin being connect with the technique hole for hoist, the upper end of the positioning pin is equipped with a nut.
Further, the supporting plate and the shackle plate are orthogonal.
Further, the reinforcing plate is arranged on side of the shackle plate far from the positioning pin.
Further, the upper end of the positioning pin is processed to trapezoidal thread and nut cooperation.
Further, the nut is screwed retaining ring.
Advantageous effect：It is convenient and efficient using this I-shaped floor steel beam lifting structure, only it need to will connect shackle
Positioning pin on special hanger installs screwed retaining ring after passing through the technique hole for hoist on I-shaped floor girder steel, is lifting
The installation and removal time of Current Collector Sleave is considerably reduced in journey, and can guarantee that girder steel is always maintained at level in hoisting process, just
It is in place in girder steel, lifting progress is greatly accelerated, in addition, the trapezoidal thread on positioning pin and screwed retaining ring are with the use of can be effective
It prevents positioning pin from coming off in hoisting process from technique hole for hoist, has reached and effectively improved lifting efficiency, safe and simple effect
Fruit.

Specific embodiment
Referring to figs. 1 to Fig. 4, a kind of I-shaped floor steel beam lifting structure of the utility model, including special hanger 10 and work
Font floor girder steel 20, special hanger 10 include supporting plate 11 and the shackle plate 12 of side, supporting plate 11 are put on supporting plate 11
The opposite side of top is equipped with the positioning pin 13 being connect with I-shaped floor girder steel 20, in the side of 12 remotely located pin 13 of shackle plate
Equipped with one piece of reinforcing plate 15 to strengthen the connection between supporting plate 11 and shackle plate 12, the upper part of positioning pin 13 is processed to
Trapezoidal thread coordinates with screwed retaining ring 14.Set at a quarter span of I-shaped 20 top flange of floor girder steel there are two about
Top flange central point technique hole for hoist 21 in a center of symmetry.
Preferably, special hanger 10 is by supporting plate 11, shackle plate 12, positioning pin 13 and strengthens for one kind as the utility model
Plate 15 is welded to form, and material is Q345B.The thickness of supporting plate 11 and shackle plate 12 is set as 20mm, the diameter of positioning pin 13
It is set as 20mm.
One kind as the utility model is preferred, in steel construction Deepen Design, in I-shaped 20 top flange of floor girder steel
A quarter span at design two technique holes for hoist 21 in a center of symmetry about top flange central point, technique hole for hoist 21
Diameter be set as 22mm, hole center to the outer peripheral distance of steel beam flange is 50mm.According to Deepen Design drawing, processed in workshop
Manufacture craft hole for hoist 21 together during I-shaped floor girder steel 20.
With reference to Fig. 3 and Fig. 5, the end of the lifting steel wire rope 40 of two equal lengths is connect respectively with two shackles 30,
Shackle 30 passes through the hole on shackle plate 12 to be connect with special hanger 10.The positioning pin 13 of special hanger 10 is from I-shaped floor girder steel
Technique hole for hoist 21 is penetrated below 20 top flange, screwed retaining ring 14 is installed, in trapezoidal thread and screwed retaining ring 14 with cooperation
Under, the connection between special hanger 10 and I-shaped floor girder steel 20 is very secured.After completing above-mentioned steps, crane can rise
It hangs, due to the equal length of two lifting steel wire ropes 40 and two technique holes for hoist 21 are in a center of symmetry about top flange center,
Therefore two 40 uniform forces of steel wire rope and ensure that I-shaped floor girder steel 20 can be always maintained at level in hoisting process.By work
Font floor girder steel 20 is hung to installation site, treats that its fixation first can remove screwed retaining ring 14, under the suspension hook of crane rearward
Drop, at the same time, special hanger 10 is detached with I-shaped floor girder steel 20, completes lifting operation.
The embodiment of the utility model is explained in detail above in conjunction with attached drawing, but the utility model is not limited to
Embodiment is stated, in the knowledge having in the technical field those of ordinary skill, this practicality can also not departed from
Various changes can be made under the premise of novel objective.
