Description
Technical field
The present invention relates to a kind of steel vestibules integrally to promote shackle structure, belongs to steel structure construction technology field.
Background technique
Since 21 century, with the continuous quickening of Urban Construction in China process, the development speed of construction industry is swift as lightning, builds
It builds higher and higher using the requirement of function and appearance and modeling；Its on the middle and senior level, super high-rise building steel gallery structure is nearly more than ten years hair
A kind of popular new structure that exhibition is got up, one side vestibule can be convenient the connection between two or more single buildings；
On the other hand its structure has unique appearance and modeling, and strong visual effect is brought to people, keeps building more characteristic；Again
Person, large-scale steel structure engineering its industrialization, commercialized degree are high, and comprehensive benefit is good, and the lifting construction time is short, the steel for construction
Structural elements can produce in factory, and assembly is completed at scene, greatly shorten the time of construction, and the recyclable benefit of steel structure material
With this respect can reduce a large amount of building waste, realize sustainable development.The construction of general high-altitude composite steel gallery structure
Technique is all to set up the construction method of high-altitude operation platform or the lifting of high-altitude single member, such construction technology with traditional scheme
The drawbacks such as big with project amount, aerial butt junction location is difficult, welding quality is difficult to guarantee, construction safety risk is high, the duration is very long.By
This had risen steel vestibule Integral synchronous lift technique in recent years, and main construction techniques are to be connected using ground steel truss moulding bed
Corridor framework integral assembling realizes that Integral synchronous promotes installation in place by computer control system by hydraulic rockshaft system
Construction method.
Steel vestibule, which is integrally promoted, needs to be equipped with upper and lower suspension centre, and upper suspension centre, which is set to, to be promoted on platform, and hydraulic jack passes through
Upper lifting-point device is connect with platform is promoted；Lower suspension centre (lifting lug) is set on the top flange of vestibule top boom, passes through steel strand wires stock
It is connect with upper lifting-point device and enters hydraulic lifting system.Vestibule after assembled integral lift unit, utilizes liquid on the moulding bed of ground
Lifting system is pressed to be promoted in place, butt welding completes vestibule installation.However, vestibule is integrally promoted and is hung since the steel vestibule scale of construction is big
Ear (lower suspension centre) device is bigger often over the design calculating post-reinforcing component scale of construction, and welding mounting construction is more troublesome, with original
Structure welding contact area is removed without readily removable greatly, destructible original structure, and input cost measure cost is high.In whole lifting process
It is centainly deformed since vestibule gravity load and lower suspension centre promote asynchronism simultaneously and will cause vestibule, influences high-altitude butt welding matter
Amount, there are security risks for lifting process.
Summary of the invention
The object of the present invention is to provide a kind of structures simply, is easily installed and reaches quality and the steel company of safety requirements
Corridor integrally promotes shackle structure, to overcome deficiency in the prior art.
Technical solution of the present invention: a kind of steel vestibule integrally promotes shackle structure, including head tree section steel plate, web,
Through-hole, power transmission securing plate, positioning splint, stiffener, suspension column, vestibule top boom and steel strand wires shutoff device, the head tree type
Steel steel plate is equipped with two groups, and the bottom of the head tree section steel plate is weldingly fixed on vestibule top boom by suspension column, at two groups
Web is provided between head tree section steel plate, and head tree section steel plate is connect with web using full penetration, the abdomen
It is welded with two pieces of power transmission securing plates on plate, the centre of the web is equipped with through-hole, among the outside of the head tree section steel plate
It is welded with positioning splint, and four sides of head tree section steel plate are welded with stiffener, the steel strand wires shutoff device is nested in abdomen
It is penetrated in through-hole on plate, and on steel strand wires shutoff device and is connected with one group of steel strand wires.
Further, temperature pier rod piece is also connected at the head tree section steel plate and vestibule top boom.
Further, using being welded to connect between the reinforcing rod piece, weld seam uses melt-through weld.
Further, the stiffener uses steel plate structure, and stiffener is connected using fillet weld, and the height of fillet weld is
10mm。
Further, four lifting lugs are arranged in four end of vestibule altogether, and lifting lug is respectively perpendicular corresponding each upper suspension centre and is promoting steel
It is welded on the top flange of the vestibule top boom at four end of vestibule unit, and four lifting lugs are arranged in four end of steel vestibule altogether, four lifting lugs are logical
Steel strand wires are crossed to connect with upper suspension centre.
Due to the adoption of the above technical scheme, the present invention has the advantages that
1, constructing operation of the present invention is simple, accurate positioning, shortens the equipment positioning test time, practical；
2, auxiliary material dosage of the invention is simplified, and does not influence convenient for later period excision and vestibule main body original structure system, can
It bears gravity laod and reaches 405t, safety reliability is high；
3, manufacturing cost of the present invention is low, is conducive to improve steel vestibule entirety improving production efficiency, can be applied to similar
In engineering.
