Description
Technical field
The present invention relates to a kind of T beams suspender and its hanging method, belongs to bridge construction ancillary equipment field.
Background technology
In road and bridge construction, prefabricated T-shaped beam needs to lift, and the conventional method lifted is first by steel wire rope lace
Hanging ring pass through the preformed hole of T-shaped beam upper limb, then bypassed from the bottom of prefabricated T-shaped beam, then from prefabricated T-shaped beam upper limb opposite side
Preformed hole be pierced by, finally the hanging ring at steel wire rope both ends is hung on the suspension hook of loop wheel machine in a manner of revealing all the details, can start to lift by crane.
Hoisting prefabricated T-shaped beam is carried out using above-mentioned steel wire rope and is primarily present following deficiency：First, the hanging ring of steel wire rope lace is through pre-
When boxing out, because the diameter of steel wire rope is big, hanging ring penetrates relatively difficult, adds working time and labor intensity；Second, using big
The steel wire rope lifting of diameter, not only of high cost and service life are short；Third, after the lifting of T beams is in place, easily disturbed when taking out steel wire rope
Beam body, causes beam body capsizing case to occur.
CN2011101523262 discloses a kind of hanging method of T-shaped beam, by penetrating stress structure in the bottom of T-shaped beam
Part, then penetrates steel suspender belt vertically in the preformed hole of T-shaped beam upper limb, and the bottom of steel suspender belt is equipped with that upper radius is big, lower part half
The small bar hole in footpath, then the steel suspender belt of T-shaped beam both sides be sleeved on by bar hole on steel pin, the top of steel suspender belt connects with suspension hook
Connect, the semicircle for slinging rear steel suspender belt lower part is stuck on steel pin, and after lifting in place, Panasonic's suspension hook, steel suspender belt moves down, bar hole top
Semicircle and knob end to it is corresponding when steel suspender belt exited under the restoring force effect of compression spring.Although steel suspender belt service life is grown, cost
It is low and relatively easy for installation, but still there are following defect：
1st, the maximum capacity point of lifting is on steel pin, and steel pin is divided into left steel pin, right steel pin, after a number of uses, steel pin meeting again
There is the situation for going out abjection from bar hole, and this can cause Hoisting Security accident, there is the risk for smashing, injuring by a crashing object；
When the 2nd, lifting by crane, the hole for hoist at steel suspender belt both ends is caught on by four suspension hooks, opereating specification span is big, and there are security risk；
3rd, through T beams bottom after steel suspender belt is passed through from T backs portion, lifting center is relatively low, and lifting is unstable while more laborious, hangs
Fill risk bigger.
The content of the invention
In view of the deficiency of the prior art, it is more reasonable the object of the present invention is to provide a kind of structure design and hang
Dress more stable T beams suspender and its hanging method.
To achieve the above object, one of the technical solution adopted by the present invention is：T beam suspenders, including body, on the body
Portion is equipped with the coiling sheave coordinated with steel wire rope, and body lower part is equipped with two vertical parallel steel arms, the bottom of two steel arms

The coiling sheave is multiple composition sheave groups.
Described two steel arms are coaxially hinged on the body.
The bottom of described two steel arms is equipped with bolt hole, and the bearing pin is located at the spiral shell between two steel arm bottoms
In keyhole, and the outside screw positioned at steel arm on bearing pin both ends is connected with Safety nut.
The two of the technical solution adopted by the present invention are：T beam hanging methods, using the T beams suspender, include the following steps：
（1）The center hole of a perforation is had on the web at T beams both ends, the upper limb of web top both sides is located on T beams
On be symmetrically provided with arm hole corresponding with the center hole；
（2）Be respectively aligned to T beams both ends using two T beams suspenders, by two steel arms of each T beams suspender respectively on to
Under through symmetrical arm hole on the upper limb of T beams and the bolt hole of steel arm bottom is directed at center hole on the web, use
Bearing pin is from the center hole run through between the bolt hole of two steel arms in T beam webs, the then bearing pin on the outside of steel arm
Safety nut is fixed at both ends, completes assembling；
（3）Lifted by crane with lifting equipment by steel wire rope, unload suspender, complete the lifting of T beams.
Center hole present position in the T beam webs is apart from upper limb bottom 50-100cm.
Above-mentioned bearing pin selects No. 45 steel columns of a diameter of 80-100mm, and bearing pin both ends are machined with and spiral shell in Safety nut
The external screw thread that line matches, and attach safety anti-falling pin；The length of steel arm is 120-180cm, and steel arm thickness is 25-
35mm。
The raising of bearing pin position, preferably ensures stability during bale handle and falls the various safety of dismounting bearing pin after beam
Risk.
Center hole generation type in above-mentioned T beam webs is：In T beam manufacturing process, by T beams designated position it is pre-
Pvc pipes are buried, reinforcing bar reinforcement are used around pvc pipes, through being expounded through peer review and calculating, to beam body quality without any damage；After the completion of lifting,
Center hole is blocked, on presentation quality without influence.
Beneficial effect
Compared with prior art, advantages of the present invention is：
1st, bearing pin is integral, and is not easy to spin off from T beams, is reduced the risk that comes off；
2nd, single wire rope multiply can be used to concentrate lifting using sheave group, effectively raises the weight limit of lifting, also contract
Small hoisting span, opereating specification reduce, and reduce opereating specification risk；
3rd, steel length of boom greatly shortens, and lifting center is improved, the stabilization after being conducive to hanging beam process and fastening, and is lifted more
Steadily, it is laborsaving；
4th, T girder prefabricated pedestals need not reserve suspension centre notch, and globality is more preferable.
The present invention can lift by crane 50m across footpaths（Nearly weigh 180 tons）T-shaped beam, have cost it is low, service life length, lifting more
For stabilization, safely and conveniently the advantages that.
