Joint connection of regeneration cubage concrete combination beam-column and construction method thereof

Abstract

The invention discloses joint connection of a regeneration cubage concrete combination beam-column. A square steel pipe regeneration cubage concrete column, a U-shaped steel-encased regeneration cubage concrete beam, a U-shaped steel connecting piece of which a bottom plate is weakened locally and the single end is widened, a steel connecting plate with a groove, and a short reinforcing bar of which the single end is provided with a thread are included. The invention further provides a construction method of joint connection of the regeneration cubage concrete combination beam-column. According to joint connection of the regeneration cubage concrete combination beam-column and the construction method thereof, on the one hand, as no core penetrating component exists in a joint core area, the problem that large-dimension waste concrete block throwing construction is difficult is solved, moreover, the procedures of rebar binding, formwork assembling, formwork disassembling and the like can be decreased by adopting a U-shaped steel-encased part, construction is convenient and rapid, and the building industrialized requirement is met; and on the other hand, by arranging the U-shaped steel connecting piece of which the bottom plate is weakened locally and the single end is widened, and the short reinforcing bar of which the diameter is smaller than that of a longitudinal rebar on the upper portion of the beam and the single end is provided with the thread, the end of the beam is formed into a plastic hinge through yielding at first so that a large amount of earthquake energy can be consumed, and the overall anti-seismic property of the structure is improved.

Description

technical field [0001] The invention relates to the technical field of waste concrete recycling, in particular to a node connection of a recycled block concrete composite beam-column and a construction method thereof. Background technique [0002] At present, the mining of natural sand and stone damages the environment and the reserves are decreasing day by day. As a precious "special resource", the recycling of waste concrete has attracted more and more attention at home and abroad. Compared with recycled coarse aggregate and recycled fine aggregate, the use of larger-scale waste concrete blocks can greatly simplify the recycling process of waste concrete. [0003] U-shaped steel-clad steel-concrete beams are a new type of composite member that has emerged in recent years. Compared with traditional reinforced concrete beams, the use of U-shaped steel-clad steel beams can not only reduce the steps of steel bar binding and formwork removal, but also significantly improve cons...

AI Technical Summary

Problems solved by technology

In addition, if the longitudinal reinforcement of the beam passes through the core area of ​​the joint according to the traditional method, it will inevitably cause great difficulties in the construction of large-scale waste concrete blocks in the column and the core area of ​​the joint.
