A High Ductility Assembly Integral Frame Edge Node Connection Structure and Construction Method

Abstract

The invention discloses a high-ductility assembled integral type frame exterior joint connection structure and a construction method thereof. Members adopted comprise a precast column and precast beams. In the assembled -type concrete frame structure, column-column connection joints are connected in the grouting manner by utilizing grout sleeves at each layer of point of inflection or points of inflection of every two layers. Connection of exterior beam-column joints is achieved in the manner of anchor grouting and bolt anchoring in joint reserved pore channels. Tensile bars at the upper part and L-shaped ribs at the lower part penetrate through the reserved pore channels and subjected to anchor grouting. End parts of anchor bars on the other side are subjected to mantle fibers and anchored. The composite beam ends and the outside of a base plate are subjected to connection and sealing of beams and columns by adoption of fiber cement composite material used for engineering.The high-ductility assembled integral type frame exterior joint connection structure and the construction method thereof have following beneficial effects: the aseismic design concept of strong columns and weak beams, strong shear capacity and weak bending capacity, and strong joints and weak members is achieved; aseismic performance of the assembled concrete framework structure is improved; and vertical members are connected by grout sleeves so that constructaion is carried out conveniently and rapidly; and the construction progress is quickened.

Description

technical field [0001] The invention belongs to the field of structural engineering, and relates to a high ductility assembled integral frame side node connection structure and a construction method, which are mainly used in the assembled integral frame structure. Background technique [0002] China's construction industry is a traditional industry with a long history. The construction industry has not only made an increasingly prominent contribution to the national economy, but also played a huge role in promoting employment, industrial linkage and other aspects. [0003] However, with the development of society, more and more contradictions in the construction industry have been highlighted: the energy consumption of the construction industry is too high, the phenomenon of dirty and messy construction sites is very common, the quality of construction is difficult to guarantee, and labor costs are rising, etc. All these phenomena show that the traditional construction indus...
