Description
Technical field
The invention belongs to building syndeton technical field, particularly relate to the steel bar connecting structure between a kind of precast reinforced concrete structure and mode thereof.
Background technology
As everyone knows, assembly concrete building have superior in quality, the duration is shorter, energy conservation, consumption reduce, produce many advantages such as clean.This adopts precast reinforced concrete structure mainly due to prefabricated concrete structure building more, uses industrialization technology to build and forms.Precast reinforced concrete structure is produced by prefabrication, is connected to become entirety at building-site by some connected modes.Therefore the bar connecting of prefabricated concrete structure is the key affecting structural safety, and the construction technology of bar connecting also has larger impact to construction quality and installation effectiveness.
Assembly concrete building is often higher to the positioning requirements of precast reinforced concrete structure docking reinforcing bar, and allowable deviation is generally 2 ~ 3mm.In practice of construction process, after the reason such as appearance and size of prefabricated units can cause prefabricated units in place, there is larger deviation in its docking reinforcing bar, cause the connection of reinforcing bar to occur a difficult problem on axis direction or abutting direction.For solving this difficult problem, the method generally adopted in the world is at present sleeve grouting connected mode.The existing national sector standard of China " prefabricated concrete structure tecnical regulations " JGJ1-2014 has carried out pertinent regulations to this connecting method for reinforcing bars adopted in prefabricated structural element.But sleeve grouting connected mode also has the shortcoming of self, is first that joint area concreting is more difficult, concrete is closely knit not.Secondly the casting technique quality requirement of sleeve is high, and cutwork amount is large, and complex procedures, processing cost is high.These problems all can limit application and the technical development of China's assembling frame structure.
Summary of the invention
In order to avoid the grouting of above-mentioned sleeve connect existing for weak point, the present invention proposes steel bar connecting structure between a kind of precast reinforced concrete structure and mode thereof.
Syndeton comprises: connector, docking reinforcing bar, bolt, sleeve, nut; Be empty in the middle of described connector, one end has the first tapped through hole, and the other end has the second through hole, and the first tapped through hole internal diameter matches with the major diameter of thread of docking reinforcing bar, and the internal diameter of the second through hole is greater than the first tapped through hole internal diameter and is less than sleeve outer diameter;
Connector is docked screw thread steel by the first tapped through hole be connected with one; Another root docking reinforcing bar is connected by bush whorl with bolt; The bolt part be exposed at outside sleeve penetrates the second through hole of connector, and sleeve is stuck in outside the second through hole of connector, fastening nut on bolt.
Described connector is high-strength steel material, and bolt is high-strength bolt, and nut is high-strength nut.
The shape of described connector 1 is any one in rectangle, circle, trapezoidal, ellipse.
Described connector 1 is frame construction or loop configuration.
Connected mode comprises:
Before prefabricated units connect, first the first tapped through hole of connector is docked screw thread steel be connected with one; Another root docking reinforcing bar is connected by bush whorl with bolt; While prefabricated units are in place, bolt penetrates the second through hole of connector, and adjustment bolt screws in the length of sleeve, make connector inner by bolt and connector by nut compact siro spinning technology, sleeve and nut torque wrench are tightened, and whether convenient inspection reaches enough moments of torsion.
Beneficial effect of the present invention is: the connecting method for reinforcing bars adopting special connector and high-strength bolt, solves the offset issue of precast unit in Practical Project docking; Connect effect firm, can ensure that building structure possesses sufficient supporting capacity, anti-seismic performance.Convenient construction transport and the requirement realizing suitability for industrialized production fast can be met, and wet trade quantity can be reduced, improve assembling ratio, simplify construction technology, reduce construction costs.
