Description
Technical field
The invention belongs to the technical field of hanging element.
Background technology
Because steel structure has the advantages such as lightweight, that anti-seismic performance good, can reuse, recent year construction steel structure proportion significantly rises.In various structures, the floor beam adopts the H section steel beam in a large number, and these girder steel spans are scarcely greater than 8 meters, and weight is seldom above 2 tons.
Do not have at present special suspender to be used for the lifting of H section steel beam, the hanging method of H section steel beam is at present: adopt two steel rope afterbody joining shackles; Steel rope is bundled in about girder steel 1/4th spans with shackle, and steel rope contacts four jiaos flexible material protection girder steel and steel rope is set with girder steel; Adjust shackle and steel rope binding point position before the lifting, in order to present horizontality behind the steel beam lifting, be convenient to the in place of girder steel; Rear dismounting shackle in place and flexible protective material.
There is following defective in the hanging method of H section steel beam at present: if binding is not tight, skidding may appear in steel rope, causes the lifting accident; The guarded by location that steel rope contacts with girder steel is bad, and paint and steel rope with the damage girder steel cause quality and safety misadventure; Shackle binding point needs repeatedly to adjust, and presents heeling condition after will making steel beam lifting, causes the girder perch difficulty; During rear dismounting girder steel in place, the flexible protective material freely descends slowly and lightly, and is difficult to collect in upper air installing.Therefore existing lift-on/lift-off system lifting H section steel beam exists the lifting work capacity large, and security-hidden trouble is more, and it is longer to take the loop wheel machine time, and erection schedule is slow.The quantity of girder steel is more in the general structural steelwork, the lifting speed of girder steel directly determines the progress of whole structural steelwork, therefore design a kind of special hanger of lifting progress of the H of raising section steel beam, the security-hidden trouble that reduces in the hoisting process is a urgent problem.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of H of raising section steel beam the lifting progress, reduce the H section steel beam special hanger of the security-hidden trouble in the hoisting process and utilize the hanging method of this suspender.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of H section steel beam special hanger, comprise the suspender body that is the open slot shape, one end of suspender body is provided with thread segment, the other end is provided with hole for hoist, is the groove that holds H section steel beam part flange plate between suspender body thread segment and the hole for hoist.
Utilize the hanging method of above-mentioned H section steel beam special hanger, may further comprise the steps:
A, offer mounting hole with H section steel beam special hanger thread segment coupling at the flange plate of H section steel beam, mounting hole is symmetrical along length and the Width of H section steel beam upper limb;
B, H section steel beam special hanger thread segment passed the mounting hole of H section steel beam, and pass through fastening nuts, be connected with shackle between nut and H section steel beam special hanger and the lifting steel rope, one end of shackle is connected with the lifting steel rope, and the other end passes two relative holes for hoist by pivot pin and is connected with H section steel beam special hanger;
C, the H section steel beam is lifted into the installation site installs;
D, install after, remove the nut on the thread segment, H section steel beam special hanger separates with the H section steel beam, finishes lifting operation.
Compared with prior art, the invention has the advantages that: 1, H section steel beam special hanger is provided with thread segment, thread segment passes mounting hole, by nut H section steel beam special hanger is connected with the H section steel beam, be connected with shackle between H section steel beam special hanger and the lifting steel rope, the H section steel beam does not directly contact with the lifting steel rope, also needn't fix by the binding of lifting steel rope, but fix by nut, easy to operate, be convenient to install, attachment point is fixed, and does not need repeatedly to adjust good fixing effect, can not occur because of skidding that binding occurs, can guarantee that the deformation of H section steel beam in the hoisting process is stable; 2, need not add flexible material on the H section steel beam, having avoided flexible material to descend slowly and lightly everywhere affects environmental health; 3, in use, screw nut on the mounting rod and can finish the installation of H section steel beam, unclamp nut on the mounting rod and can finish the dismounting of H section steel beam, reusable, Assembly ﹠Disassembly is convenient, obviously reduce the Assembly ﹠Disassembly time of lifting, accelerated the job schedule of lifting, thereby accelerated the progress of whole structural steelwork.
Further, when mounted, lifting steel rope and H section steel beam special hanger are an angle, can apply to H section steel beam special hanger the power of horizontal direction, are easy to destroy the thread segment of H section steel beam special hanger.In order to protect the thread segment of H section steel beam special hanger; the mounting hole line of centers equals H section steel beam special hanger thread segment line of centers to the distance of other end cell body inwall to the distance in the H section steel beam flange plate outside among the described step a; can guarantee that the H section steel beam flange plate outside is in the state of pushing against with H section steel beam special hanger cell body inwall, is born the power of above-mentioned horizontal direction by the cell body inwall.
Further, the quantity of mounting hole is four among the described step a, and mounting hole is opened in distance H section steel beam end
The L place, wherein, L is the overall length of H section steel beam, this moment, the deflection of H section steel beam was minimum.
Description of drawings
Below in conjunction with drawings and Examples technical solution of the present invention is further specified:
Fig. 1 is the structural representation of H section steel beam special hanger embodiment of the present invention;
Structural representation when Fig. 2 and Fig. 3 are H section steel beam special hanger use of the present invention.
