Description

A kind of T beams suspender
Technical field
The utility model is related to a kind of T beams suspender and its hanging methods, belong 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-type beam upper limb, then bypassed from the bottom of prefabricated T-shaped beam, then from the prefabricated T-shaped beam upper limb other 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-type 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 across pre- When boxing out, because the diameter of steel wire rope is big, hanging ring penetrates relatively difficult, increases working time and labor intensity;Second is that using big The steel wire rope of diameter lifts, and not only of high cost and service life is 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-type beam, by penetrating stress structure in the bottom of T-type beam Part, then penetrates steel suspender belt vertically in the preformed hole of T-type beam upper limb, and the bottom of steel suspender belt is equipped with that upper radius is big, lower part half The small strip-shaped hole of diameter, then the steel suspender belt of T-type beam both sides be sleeved on steel pin by strip-shaped hole, the top of steel suspender belt connects with suspension hook It connects, 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, strip-shaped hole top Semicircle and knob end to it is corresponding when steel suspender belt exited under the reply force effect of compression spring.Although steel suspender belt service life is long, cost It is low and relatively easy for installation, but still have the following defects:
1, the maximum capacity point lifted by crane is on steel pin, and steel pin is divided into as left steel pin, right steel pin, after a number of uses, steel Pin, which has from strip-shaped hole, goes out the case where deviating from, and this can lead to Hoisting Security accident, there is the risk for smashing, injuring by a crashing object;
When 2, 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 safety winds Danger;
3, go directly T beam bottoms portion after steel suspender belt is passed through from T backs portion, and lifting center is relatively low, unstable while lifting is more laborious It is fixed, lift risk bigger.
Utility model content
In view of the deficiency of the prior art, it is more reasonable to be to provide a kind of structure design for the purpose of this utility model And the T beams suspender and its hanging method that lifting is more stable.
To achieve the above object, one of the technical solution adopted in the utility model is:T beam suspenders, including ontology, described Body top is equipped with the coiling sheave that coordinate with steel wire rope, and body lower part sets that there are two steel arm parallel vertically, two steel arms Bottom between be equipped with dismountable bearing pin.
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.
Advantageous effect
Compared with prior art, it is the advantages of the utility model:
1, bearing pin is integral, and is not easy to detach from T beams, is reduced the risk that falls off;
2, single wire rope multiply can be used to concentrate lifting using sheave group, effectively raises the weight limit of lifting, Also hoisting span is reduced, opereating specification reduces, and reduces opereating specification risk;
3, 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 It is more steady, laborsaving;
4, T girder prefabricated pedestals need not reserve suspension centre notch, and globality is more preferable.
The utility model can lift by crane 50m across footpaths(Nearly weigh 180 tons)T-type beam, have it is at low cost, service life is long, hangs Fill it is more stable, safely and conveniently the advantages that.
