Description
Technical field
The present invention relates to technical field of bridge engineering, more particularly, to a kind of individual layer steel bar arrangement using UHPC grouting materials
Bridge superstructure seam.
Background technology
Prefabricated bridge structure has become the trend of bridge construction, the seam of previous bridge prefabrication superstructure
In, for generally use normal concrete as grouting material, seam steel bar arrangement includes straight reinforcement welding, steel hoop welding, annular
Bar splicing, the steel bar arrangement with pier nose, and be mostly two layers of reinforcing bar form, only small part steel bar arrangement shape by steel bar arrangement
Formula uses individual layer reinforcing bar form, but either butt welding processing or reinforcing bar one end set pier nose to reinforcing bar.Using UHPC (superelevation
Can concrete) seam as joint grouting material when, arrangement of the seam steel bar arrangement for double-deck straight reinforcing bar or steel hoop overlap joint
Form, without the arrangement form of individual layer reinforcing bar.
Traditional normal concrete reinforcement welding seam construction is extremely complex, improves seam steel bar arrangement form, uses UHPC
After grouting material, seam construction efficiency has obtained large increase.The complexity of bridge top precast construction seam directly affects bridge
The construction cost of beam and duration, thus in the case that possible, it is necessary to the construction of seam is further simplified, it is prefabricated to improve
The construction efficiency of assembled bridge promotes the economic benefit of bridge construction.
Invention content
The present invention is directed to the form design problem of the cast-in-place seam of bridge prefabrication assembly superstructure, and provides a kind of use
The bridge superstructure seam of the individual layer steel bar arrangement of UHPC grouting materials, the purpose of the present invention is on prefabricated bridge is ensured
It is simple as much as possible by the simplification of steel bar arrangement and the use of new material UHPC on the basis of portion's structure seam stress performance
Change the structural form of seam, seam is facilitated to construct to reach, and then realize the purpose that economic benefit and social benefit are promoted.
The purpose of the present invention can be achieved through the following technical solutions：
Using the bridge superstructure seam of the individual layer steel bar arrangement of UHPC grouting materials, tied including two precast bridge tops
Structure component and the seam UHPC being cast between two precast bridge superstructure components, cloth in precast bridge superstructure component
Put precast bridge superstructure component transverse steel, precast bridge superstructure component longitudinal reinforcement, precast bridge superstructure
Component bearing rod and seam reinforcing bar, the seam reinforcing bar are individual layer reinforcing bar, and precast bridge superstructure is goed deep into seam reinforcing bar one end
In component, the other end is exposed outside the interface of precast bridge superstructure component, two precast bridge superstructure components
Interface be oppositely arranged, the seam reinforcing bar of two precast bridge superstructure components is staggered, and seam UHPC is prefabricated by two
Including the seam reinforcing bar of bridge superstructure component pours.
Precast bridge superstructure component transverse steel, precast bridge superstructure component longitudinal reinforcement and seam reinforcing bar
Entirety is connected as by precast bridge superstructure component bearing rod, steel reinforcement cage is formed, coagulation is poured on the basis of steel reinforcement cage
Soil forms precast bridge superstructure component.
In precast bridge superstructure component, on the precast bridge superstructure component transverse steel, precast bridge
Portion's structural elements longitudinal reinforcement is equipped with bilayer.Precast bridge superstructure component transverse steel, precast bridge superstructure structure
Part longitudinal reinforcement is double steel bar as stress main reinforcement.
The precast bridge superstructure component transverse steel, precast bridge superstructure component longitudinal reinforcement are prefabricated
It blocks, i.e., is not stretched out outside the interface of precast bridge superstructure component at the interface of bridge superstructure component.
The exposed steel bar end outside the interface of precast bridge superstructure component of seam reinforcing bar is without appointing
Where is managed, until seam is connected as one when constructing with field cast-in-place seam UHPC.
The seam reinforcing bar is placed and is bound on precast bridge superstructure component transverse steel top.
The precast bridge superstructure component is connected to become entirety by pouring for UHPC at the construction field (site), shared
Load on bridge.
The present invention is using the bridge superstructure seam of the individual layer steel bar arrangement of UHPC grouting materials in bridge superstructure
Play the role of moment of flexure and Shear transfer, i.e., the internal force of a precast bridge superstructure component is transferred to next prefabricated bridge
Beam superstructure component.After bridge upper load generates internal force in a precast bridge superstructure component, work as internal force
When being transferred to seaming position, on the one hand directly internal force is transferred in UHPC by the adhesive property of interface, it is on the other hand logical
Seam reinforcing bar is crossed internal force is transferred in UHPC indirectly, the internal force in UHPC again by interface adhesive property and reinforcing bar biography
Internal force is transferred in next precast bridge superstructure component by power mechanism, realizes that internal force is in seaming position in structure with this
It transmits.
Compared with prior art, it is an advantage of the invention that simplifying the steel bar arrangement form of seam, the reinforcing bar cloth in seam
The arrangement form of only individual layer reinforcing bar is put, and reinforcing bar need not be handled, avoid the reinforcing bar processing work of construction site complexity, reduce
The possibility that reinforcing bar between prefabricated components collides, and then accelerate construction progress, promote economic and social benefit；Simultaneously
UHPC's is used cooperatively the purpose that can be realized and improve seam stress performance, so as to ensure the safe and reliable of seam.
