Reinforced concrete belt steel ring plate connecting joint used for precast beam column and connecting method

Abstract

The invention relates to the technical field of connecting joints, in particular to a reinforced concrete belt steel ring plate connecting joint used for a precast beam column and a connecting method.The connecting joint comprises a precast column and a plurality of precast beams which are arranged around the precast column, wherein the center line on which the circle center of a circle enclosedby the precast beams is located is coaxial with the center axis of the precast column; a reinforcing steel bar, positioned at the outer layer, in the precast column extends in a direction away from the precast column, and a reinforcing steel plate is arranged on the extended reinforcing steel bar; connecting reinforcing steel bars which are arranged towards the reinforcing steel plate are arrangedon the precast beam; the connecting reinforcing steel bars are fixedly connected to the reinforcing steel plate; and concrete layers are poured between the precast column and the precast beams. In aprocess of the connecting method, the novel connecting joint structure is adopted. A series of problems generated by connecting reinforcing steel stacking and placing in the prior art are solved, connection of the reinforced ring beam joint is realized through a brand-new connecting joint structure and a brand-new connecting method, and a construction process is simplified; and moreover, the connected ring beam joint is higher in compactness, is higher in stress strength and is better in anti-seismic property.

Description

technical field [0001] The invention relates to the technical field of connecting nodes, in particular to a connecting node and a connecting method of a reinforced concrete strip steel ring plate used for prefabricated beams and columns. Background technique [0002] Reinforced ring beam is a multi-node building structure used to strengthen the envelope and improve the seismic resistance of the structure. Generally, multiple prefabricated beams need to be connected around the prefabricated column. The specific method is to use multiple prefabricated beams to surround the prefabricated columns. The prefabricated columns and multiple prefabricated beams are connected in the form of steel bars, and then tied to each other. Finally, the concrete is poured as a whole to strengthen the strength of the connection nodes and provide seismic performance. [0003] However, in some modern buildings, due to the diverse design requirements of customers, multiple prefabricated beams are u...

Problems solved by technology

[0004] Under such circumstances, the traditional method has the following problems: from a structural point of view, the traditional method of steel connection is used, and the steel bars at the connection node are relatively dense, and the steel bars need to be bent and interspersed on the opposite prefabricated beam. The stress on the steel bars may be due to the fact that too many steel bars are erected and knotted to easily form stress-bearing strength areas and weak areas, resulting in uneven concrete pouring and uneven stress on the connecting nodes; Many branches affect the beauty of the building itself; from the construction point of view, due to the large number of prefabricated beams, the construction cost of the joints is high, and the formwork support calculations during the construction process are numerous and complicated, and it is difficult to ensure the accuracy of the construction
