Description

A kind of prefabricated concrete structure connection method
Technical field
The present invention relates to a kind of prefabricated concrete structure connection method.
Background technology
The industrialization of building trade has turned into the direction that Building Trade in China develops, during construction industry is industrialized, will Building with site operation build based on present situation be changed into prefabricated with batch production, the form that assembled in situ mode is built just turns into It is inevitable.At present, the building of China's extreme portions is built using cast-in-situ steel reinforced concrete technology.With assembly concrete The popularization and application of technology, in order to ensure that prefabricated concrete structure is not less than cast-in-place concrete structure, China in structural behaviour Also corresponding concrete structure technique code is formulated, including from structure design to element precast and in terms of site operation, substantially Thinking is by links such as rational fractionation, factory-made component, on-site consolidations by cast-in-place concrete structure.Wherein split favourable In prefabrication, the structure after on-site consolidation, and assembly is also conducive to meet the security and Functional Requirement of structure.For This, occurs in that the fractionation of diversified forms and assembled connected mode, and its connected mode directly influences speed of application and structure safety Property, more widely paid close attention to.Conventional connected mode has sleeve grouting connected mode, slurry anchor overlap joint connected mode at present, its In it is most with sleeve grouting connected mode application, sleeve grouting connected mode is combined with slip casting and anchorage style, will be due to The structure reinforcing bars for splitting and being disconnected are reconnected in splicing section part.Specific practice is to will be switched off one end conduct of reinforcing bar Female end, screw thread is processed into steel bar end, is connected with one end of steel bushing, and steel bushing is that one end is connected with screw thread steel, separately The cylinder of one end open and stack shell provided with injected hole, cylinder opening end diameter is more than reinforcing bar, is open and determines as the entrance of female end On the design attitude of prefabricated components;The other end that reinforcing bar is disconnected overhanging one section of reinforcing bar in element precast, stretches out reinforcing bar Length be less than or equal to the connecting length of steel bushing, will as the connection male end of precast concrete when assembled at the scene Protruding bar inserts the openend of steel bushing, is connected in whole reinforcing bars, after component is by design in place, passes through reserved injected hole Toward injection connection glue in steel bushing, reinforcing bar is reconnected it is integral, while also making prefabricated components connection integral.
The major defect that exists in practice of sleeve grouting connected mode have it is following some, one is steel bushing cylinder size is big, Reduce concrete cover;The second is grouting quality can not ensure, it can not more ensure note especially in the connection of horizontal member The plumpness of slurry;The third is the durability of anchor adhesive not yet obtains practical proof, connection long-term reliability leaves a question open, and is exactly finally to work as Under conditions of section amount of reinforcement is more, Joining Technology is complicated, and speed of application is slow.
The content of the invention
In order to overcome the shortcomings of that complex process, the reliability of existing prefabricated concrete structure connected mode are poor, this hair A kind of bright technique of offer simplifies, the preferable prefabricated concrete structure connection method of reliability, straight by steel bar anchoring converter Connect and be attached reinforcing bar using mechanical means, steel bar anchoring converter does not influence the protective layer thickness of reinforcing bar, can reduce because of dress Reduction with connection to concrete cover;The transport of prefabricated components can be made with hanging so that overhanging connection reinforcing bar need not be reserved Dress is more convenient.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of prefabricated concrete structure connection method, comprises the following steps:
1) makes steel bar anchoring converter, and the steel bar anchoring converter includes bottom plate, power transmission side plate and closing side plate, The power transmission side plate is symmetricly set on the both sides of the bottom plate, and described bottom plate one end sets the closing side plate, and the bottom plate is another One end is opening, and the upper end of the power transmission side plate at the top of the steel bar anchoring converter with connecting, the steel bar anchoring conversion The top of device is provided with the bar connecting hole being connected with reinforcing bar one end, and the bottom plate is provided with bolt connecting hole;
2) reinforcing bars are connected with steel bar anchoring converter one end;
3) presses design requirement spacer bar and steel bar anchoring converter in component, and sets anti-in component connecting end surface Cut groove, casting concrete formation prefabricated components;
4) selects the connecting bolt between steel bar anchoring converter;
5) when completes whne prefabricated components and is transported to job site and installed, by the connection end of two prefabricated components Face is fitted and alignd, and at this moment the steel bar anchoring converter end face on two prefabricated components also all should fit and align;
6) bolt is passed through the bolt connecting hole on steel bar anchoring converter and is screwed to preset torque by, successively will be all After steel bar anchoring converter has been bolted, two prefabricated components have been also coupled to together.
Further, methods described is further comprising the steps of:7) uses cement mortar grouting material by steel bar anchoring converter Space fill up.
It is preferred that, the steel bar anchoring converter also includes top plate, and symmetrical both sides set institute between the top plate and bottom plate Power transmission side plate is stated, one end sets the closing side plate between the top plate and bottom plate, and the other end is between the top plate and bottom plate Opening, the top plate is provided with the bar connecting hole being connected with reinforcing bar one end.According to the program, steel bar anchoring converter is in isosceles It is trapezoidal;The top plate can also be given up when necessary, top be formed by being joined directly together at the top of two blocks of power transmission side plates, now in reinforcing bar Force transducer is in isosceles triangle shape.
The present invention technical concept be:Ensure that the mechanical performance that reinforcing bar is reconnected after disconnecting is constant, that is, control is each The intensity of connecting link, is not less than whole reinforcing bar with the reliability and security for ensuring connection.The core of the present invention is to apply steel Different connection sections of the force transducer in various concrete structures, solve the embedded of steel bar anchoring converter and connect in muscle, It is characterized in ensure that the line of force for connecting reinforcing bar two ends keeps non-deviation state, and the pulling force and pressure of reinforcing bar can be transmitted Power.
Set up on existing reinforcing bar and Steel Structural Design standard, normative foundation, after the completion of the Concrete Structure Design, The reinforcing bar for needing to connect just is can determine that, the basic parameter using reinforcing bar nominal diameter as connection is attached design, will in factory Steel bar anchoring converter and the connection of member reinforcing steel bar one end, and complete element precast;Can be directly with bolt by two ends in engineering site It is connected.
Beneficial effects of the present invention are mainly manifested in:Directly reinforcing bar is entered using mechanical means by steel bar anchoring converter Row connection, steel bar anchoring converter does not influence the protective layer thickness of reinforcing bar, can reduced because assembly connection is to concrete cover Reduce;So that overhanging connection reinforcing bar need not be reserved the transport of prefabricated components and lifting can be made more convenient.
