Description
Technical field
This utility model belongs to science of bridge building field, relates to Pre-Stressed Concrete Composite Box-Girder Bridge with Corrugated Steel Webs during incremental launching construction
The Guide beam structure used.
Background technology
At present, the steel I-beam example as Wavelike steel webplate PC combination beam nose girder of band Wavelike steel webplate has been used.
The corrugated web of usual this nose girder is after arranging enough sway bracings, and the instability modes of structure is local buckling, unstability
Position occurs near nose girder bearing.This position shearing and local pressure are the biggest.Under the corrugated web nose girder that this explanation is simple
The bending resistance on the edge of a wing and local bearing capacity are more weak, are susceptible to local buckling during incremental launching construction.In order to improve web bottom wing
The stress performance of edge and local bearing capacity, need to strengthen web lower flange.In view of under steel nose girder during bridge incremental launching
Also differ the such a distance of underplate concrete thickness between the edge of a wing with the bearing of actual bridge, therefore lower flange can be arranged
Steel boots, are connected on web lower flange, on the one hand improve the local pressure of nose girder lower flange, on the other hand solve nose girder and bearing
Clearance issues.
Visible, objectively need to research and develop a kind of wave forms steel web Guide beam structure, by nose girder girder web plate and under
The edge of a wing carries out extending lengthening and forms strip steel boots structure, without removing steel boots after pushing tow puts in place, direct casting concrete roof and floor
After can be used as main bridge a part use.Steel boots not only ensure that nose girder bottom surface is concordant with the bottom surface of Combined concrete girder,
The bending resistance of structure can also be improved, increase structural stability, improve partial pressing's performance, and become the steel boots conduct of bridge stage
The stiff skeleton of concrete floor improves the margin of safety of structure, has for the development of incremental launching construction technique in bridge structure
Highly important meaning.
Utility model content
The purpose of this utility model is to provide the Wavelike steel webplate Guide beam structure of a kind of strip steel boots, it is ensured that Wavelike steel webplate
Nose girder with combination girder bottom surface concordant, to realize the incremental launching construction of bridge, improve simultaneously nose girder lower flange bending resistance and
Partial pressing's performance, to ensure construction safety；And steel boots are left the stiff skeleton of concrete floor, thus reach to save
Material, exempts the purpose removing operation.
In order to achieve the above object, this utility model is by the following technical solutions:
The Wavelike steel webplate Guide beam structure of strip steel boots of the present utility model includes by nose girder girder, upper bottom lateral bracing, vertically horizontal stroke
Traditional Wavelike steel webplate nose girder of support composition and nose girder steel boots, compared with traditional Wavelike steel webplate nose girder, this utility model exists
Steel boots structure it is fixedly connected with on the bottom wing listrium of nose girder girder；Described nose girder steel boots are by steel boots top board, steel boots web, steel boots
Base plate and steel boots ribbed stiffener composition；On described steel sole plate, the fixing monoblock steel boots web that connects forms combination plate, described web
Interval, both sides is fixedly connected with stiffener；The upper limb of described steel boots combination plate is fixing with the lower flange of nose girder girder to be connected.
The described I-beam that nose girder girder is two panels band Wavelike steel webplate, web can use different bellows-shaped.
Described nose girder steel boots are made up of steel boots top board, steel boots web, steel sole plate and steel boots ribbed stiffener, and steel boots top board leads to
Being often the bottom wing listrium of nose girder girder, quantity and position relationship according to steel boots web can be divided into i shaped steel boots and box steel
Boots.
Described i shaped steel boots use i shaped cross section, only one block web, overlap with corrugated web centrage, web
Continue to pass through ribbed stiffener to arrange.
Described box steel boots are made up of two blocks of webs, and two blocks of webs are arranged symmetrically with along corrugated web centrage, respectively
Corresponding to crest and the trough of Corrugated webs, web continues to pass through ribbed stiffener and arranges.
Described steel boots structure need not be cut off after pushing tow puts in place, can direct formwork erection casting concrete roof and floor formation group
Close beam.
Owing to have employed such scheme, this utility model has the advantages that
Use welding combination plate and plate of putting more energy on Wavelike steel webplate bottom flange to form nose girder boots foot, can make to lead
Soffit is concordant with combination beam bottom surface, it is ensured that incremental launching construction is smoothed out.Pushing tow need not cut off steel boots combination plate after putting in place, directly
Connect formwork erection casting concrete and can form combined beam structure, not only save material but also accelerate speed of application.The setting of steel boots can also carry
The bending resistance of Guide beam structure, stability and partial pressing's performance in high incremental launching construction, and becoming the bridge stage as concrete bottom
The stiff skeleton of plate increases the margin of safety of structure.
