The utility model is realized with following technical scheme: the prefabricated assembled tower crane in a kind of I-shaped cross-section, the plane is a cross, comprise a plurality of members of forming by 3 kinds of form of structure, the tower crane interposition is equipped with entity component, entity component respectively be equipped with an I-shaped cross-section member all around, the I-shaped cross-section member be equipped with another kind of I-shaped cross-section member in the outer part, the prestressed reinforcement hole that perforation is arranged on the joint face of above-mentioned each member, stretch-draw is connected to form integral body to each member in the prestressed reinforcement hole by prestressed reinforcement is inserted into, balancing weight is arranged at tower crane top, it is characterized in that: the cross section of I-shaped cross-section member is I-shaped, and is fluted and protruding on each component sidewall.
Fluted on each face around the described entity component.
The I-shaped cross-section of differing for last bottom flange size in member middle part, described I-shaped cross-section, the two ends, I-shaped cross-section are that concrete seals diaphragm, on the joint face of this member and entity component projection is arranged, with fluted on the joint face of member, on the I-shaped edge of a wing of this I-shaped member bolt hole is arranged, in the I-shaped web reserving hole is arranged.
The I-shaped cross-section of differing for last bottom flange size in member middle part, described another kind of I-shaped cross-section, the both sides, I-shaped cross-section are that concrete seals diaphragm, on the joint face of this I-shaped cross-section member and I-shaped cross-section member projection is arranged, there is bolt hole the I-shaped top flange of I-shaped cross-section member.
The beneficial effects of the utility model: this tower crane is easy for installation, saves cost, and each is approaching to stability, does not have weak axle, and resistance to capsizing is good.Member adopts the I-shaped cross-section, and not only economical with materials, and feasible basis and tower crane are easy to connect.Groove on the sidewall of each member and bossing agree with mutually that the shear resistance that makes between member increases greatly and weight mass guarantees easily, and the easy removal of mass can be applicable to the tower crane of all kinds and model.

The specific embodiment
As shown in the figure: the prefabricated assembled tower crane in a kind of I-shaped cross-section, this tower crane comprises a plurality of members of being made up of 3 kinds of form of structure, described basic interposition is equipped with entity component 1, entity component 1 respectively be equipped with I-shaped cross-section member 2 all around, I-shaped cross-section member 2 be equipped with I-shaped cross-section member 3 in the outer part, after agree with mutually by groove 7-1 on its sidewall and protruding 7-2 in the prestressed reinforcement hole 8 that perforation is arranged on the joint face of each member, each member prestressed reinforcement inserted in the prestressed reinforcement hole 8 and be connected to form integral body.
Described entity component 1 is the fluted 7-1 of each face difference all around, and the prestressed reinforcement hole 8 of perforation is arranged on each face of entity component.
Described I-shaped cross-section member 2, the I-shaped bottom flange size that goes up differs, the both sides that link to each other at two members of itself and other have concrete to seal diaphragm 10, the both sides concrete seals fluted 7-1 and protruding 7-2 on the diaphragm, there is bolt hole 6 I-shaped top flange, and the prestressed reinforcement hole 8 of perforation is arranged on I-shaped cross-section member and the face that other members are connected.Reserving hole 9 is arranged in the web of I-shaped cross-section.
Described I-shaped member 3, the I-shaped bottom flange size that goes up differs, respectively there is a block concrete to seal diaphragm 10 in I-shaped both sides, sealing at its side concrete that is connected with other members has protruding 7-2 on the diaphragm, there is bolt hole 6 top flange, I-shaped cross-section, and what perforation was arranged on face that the I-shaped cross-section member is connected with other members and the face by the basis outside has a prestressed reinforcement hole 8.
The course of work: the tower crane position should be reserved by first unwrapping wire in the job site, and then at tower crane position excavation pit, excavation should be poured into a mould concrete cushion after finishing on foundation ditch.Require the bearing capacity of foundation soil under the column foot to meet the demands,, should carry out beating bed course again after ground is handled as not satisfying.Behind the bed course casting complete, find the permanent position of each member at bed course top unwrapping wire, at first entity component 1 is lifted the precalculated position again, then four I-shaped members 2 are being lifted the precalculated position, member 1,2 is connected together, again member 3 is lifted the precalculated position, the groove 7-1 and the protruding 7-2 of each member agree with the formation base integral mutually.Then reinforcing bar is inserted in the reinforced hole 8, and with two ends anchoring behind the reinforced bar stretching, each member connects and can finish.
After the basis connection is finished, can between member, place balancing weight 4 and 5 as requested.Then at basic top earthing, after finishing, earthing again the tower crane first segment is lifted the position of member bolt hole 6, bolt is inserted in the bolt hole 6, under the edge of a wing of member 2,3, connect nuts then, member 2 part bolts connecting bolt cap in hole 9, after the first segment tower crane connects, top tower crane one is being saved assembly unit to the precalculated position.This moment, tower crane can carry out work.
Tower crane top one can be saved after the tower crane operation finishes unload remove after, again the bolt in the bolt hole 6 is taken off, tower crane is from the basis behind the removal, again with balancing weight 4 and 5 removals, at last can be with the ground tackle removal of prestressed reinforcement, extract prestressed reinforcement, each member is separated, this moment, the tower crane removal was finished.After each member of tower crane separates, each lifting component can be transported to other on-the-spot continuation and use.
