Historic reservation is since environment has particularity, thus construction has to comply with the relevant laws and regulations of historical relic's protection,
Work progress adheres to the principle of minimum of interference, the disturbance of strict control construction personnel and mechanical equipment to historical relic.Historical relic is lost
The construction of location area is then directly forbidden to use big machinery construction, using manually constructing.However construction can not in historic reservation
It avoids that steel girder erection work can be encountered, due to the influence of construction environment, large-scale hoisting machinery can not be in historic reservation operation.
So the steel girder erection work of historic reservation becomes the difficult point of cultural sight area construction.
Existing historic reservation steel girder erection mode:
1) scaffold.Construction area sets up full hall scaffold, and the arrangement of scaffold upright rod avoids cultural sight area.Foot
After the completion of hand cradle is set up, artificial vertical lifting is carried out by scaffold and sets up girder steel.
2) winch hoister device.Construction area sets up small-sized scaffold, and cultural sight area is avoided in scaffold building position.
Winch hoister is installed after the completion of scaffold building, vertical transport girder steel is carried out by winch hoister and cooperates artificial progress frame
If.
3) cock device for hoisting.Construction area sets up small-sized scaffold, and cultural sight area is avoided in scaffold building position.Foot hand
Frame installs cock device for hoisting after the completion of setting up above, hangs vertical transport girder steel by cock, and cooperate and manually set up.
The steel girder erection device disadvantage of existing historic reservation is main are as follows:
1, space occupied is big, serious waste of resources, and existing vertical transport process must set up scaffold.Scaffolding work one
As occupied space it is larger, the wastings of resources such as steel pipe are more serious.
2, construction is inconvenient, because existing steel girder erection device must be support with scaffold, thus before steel girder erection implementation
Scaffold must be first set up, scaffold is dismantled after erection, work progress is extremely inconvenient.
3, it can not shift, carry not flexible.Steel girder erection device can only carry out steel girder erection in fixed location, be converted to
First it must dismantle and reinstall elsewhere.Steel girder erection process is not flexible, is unable to satisfy in text guarantor's engineering steel on a large scale
Beams Erection Construction.
For disadvantages mentioned above, this patent makes convenient, flexible steel girder erection device using steel pipe, reinforcing bar and pulley.

Cord, one end of wirerope are connected with hook, and the other end of wirerope is connected with hoist engine, and the lower part of supporting steel pipe is fixedly connected
The reinforcing bar for having several claw types to arrange, the lower end of supporting steel pipe are set in the upper end of bottom column steel pipe, the steel of claw type arrangement
Muscle is for playing the role of fixed supporting steel pipe.
Further, a trunnion axis is fixedly connected on the supporting steel pipe, trunnion axis passes through the supporting steel pipe, the cunning
Wheel is rotatablely connected by bearing and horizontal rotating shaft.
Further, the reinforcing bar includes upper support bar and lower vertical bar.
Further, the upper support bar is tilting bar or curved rod.
The utility model has the beneficial effects that
1, the utility model does not set up scaffold during steel girder erection, reduces construction area space, saves
Resource.
2, the utility model erection girder steel is fast flexible, is easily installed and dismantles.
3, the material of the utility model production is less, and manufacturing process is simple and fast, at low cost, high production efficiency.
4, the utility model has adhered to " minimum of interference " principle during assembling and steel girder erection, can effectively protect historical relic
The historical relic of protection zone is more applicable in the construction of historic reservation steel girder erection.
5, the utility model can be recycled, and save resource and cost, belong to energy-saving and environment friendly product, and application prospect is wide
It is wealthy.
6, the utility model saves manually during steel girder erection, reduces working procedure, can save and be constructed into
This.
7, it is short to carry out the steel girder erection construction time for the utility model, can effectively shorten the construction period of steel girder erection.
8, the utility model sets up the steel girder erection in building engineering construction field and is applicable in, and application range is wider.
