The joint is mainly formed by connecting a superposed concrete beam and a precast concrete column through sleeve steel bars and prestressed tendons. The superposed concrete beam is formed by pouring a prefabricated concrete beam and a post-cast superposed layer, and a first corrugated pipe hole is reserved in the axial direction of the superposed concrete beam. The prefabricated concrete column is provided with two corrugated pipe holes, wherein the first corrugated pipe hole is as high as the first corrugated pipe hole of the superposed concrete beam and is used for arranging prestressed ribs; the second corrugated pipe hole is reserved above the first corrugated pipe hole, and sleeve steel bars which stretch across the precast concrete columns and extend into the superposed concrete beam are arranged in the second corrugated pipe hole. The sleeve in the embedded shear-energy consumption dual-function sleeve steel bar beam-column joint can provide strong restraint for energy consumption steel bars, and meanwhile, the sleeve can effectively improve the shear resistance on a beam-column connecting interface.
Description
Technical Field
The invention relates to an embedded shear-energy consumption dual-function sleeve reinforced beam-column joint, belonging to the field of prefabricated reinforced concrete member connecting frameworks.
Background
With the transformation and upgrading of the building industry, fabricated buildings are more and more concerned by the engineering field. The prestressed fabricated concrete frame structure is widely applied to buildings such as various houses and office buildings as an industrial structure form. For the prestress assembly type concrete frame structure, the performance of the connection interface of the precast beam and the precast column plays a crucial role in the performance of the assembly type concrete frame structure.
A prestressed concrete assembled (RC) frame is a typical "non-equivalent cast-in-place" assembled RC frame. Early researches find that the joint has good self-resetting capability by adopting unbonded prestressed tendons for tensioning and anchoring, but the prestressed tendons are always in an elastic stage, the hysteresis loop area of the joint is small, and the energy consumption capability is relatively poor. In order to improve the energy consumption capability of the node, a large number of energy consumption elements are subsequently proposed and applied to the prestressed fabricated RC frame node. Relevant test results show that the prestress assembly type RC frame node has considerable energy consumption capability and strong deformation recovery capability by additionally arranging energy consumption elements.
The prestress assembly type RC frame node is mainly characterized in that the node is assembled by tensioning a prestress rib and pressing a precast beam column, and the shearing resistance of a connecting interface of the precast beam and the precast column is mainly provided by the friction force of the interface. Once the prestress fails, the vertical bearing capacity of the prestress assembly type RC frame node is greatly reduced, and then the collapse of the structure is induced. The existing energy dissipation element of the prestress assembly type RC frame node can improve the energy dissipation and shock absorption capacity of the node, but cannot effectively improve the shearing resistance of a beam-column connection interface. Therefore, the invention provides an embedded shear-energy consumption dual-function sleeve reinforced beam-column node which has good energy consumption capability and shear resistance capability of a beam-column connecting interface.

Advantageous effects
According to the embedded shear-energy consumption dual-function sleeve reinforcing steel bar beam-column joint, the middle sleeve can provide strong restraint for energy consumption reinforcing steel bars, and concrete damage caused by the fact that the energy consumption reinforcing steel bars extrude peripheral concrete under the action of an earthquake is avoided.
