Abstract

The invention relates to an energy consumption support and assembly type concrete framework dual energy consumption node and an assembly method. The mode comprises a beam end embedding unit, a column end embedding unit, a connecting unit and a connecting assembly, wherein the connecting unit is connected with the beam end embedding unit and the column end embedding unit; and the connecting assembly is used for connecting the beam end embedding unit, the column end embedding unit and the connecting unit. During the assembly, firstly, a prefabricated concrete beam with the beam end embedding unit, a prefabricated concrete column with the column end embedding unit and the connecting unit are firstly prefabricated; then, the prefabricated concrete beam and the prefabricated concrete column are hoisted to designed positions; a beam end embedding metal plate and a beam end connecting plate of the connecting unit are oppositely attached together; a column end connecting plate and a column end embedding metal plate are oppositely attached; and the beam end embedding unit, the column end embedding unit and the connecting unit are connected into a whole. The mode and the assembly method have the advantages that the full assembly type connection is adopted, so that the connection is safe and reliable; the structure is reasonable; the construction difficulty is low; the field construction is convenient and fast; and the work intensity is low.

Description

technical field [0001] The invention belongs to the technical field of connection nodes of building structures, and in particular relates to a dual energy-dissipating node of an energy-dissipating support and an assembled concrete frame and an assembly method. Background technique [0002] The prefabricated concrete frame structure has the advantages of saving water, energy, land and materials, reducing construction environmental pollution, and improving construction efficiency. However, when the floor height is high, the span is large, and the plane and elevation are irregular, the seismic performance of the prefabricated concrete frame is not enough. At this time, the seismic performance of the prefabricated concrete frame can be improved by setting energy-dissipating supports. [0003] At present, energy-dissipating braces are mainly used in cast-in-place reinforced concrete frames and existing reinforced concrete frames. Energy-dissipating braces are mainly connected to ...

Problems solved by technology

These existing connection methods are difficult to apply to prefabricated concrete frames, which are mainly reflected in: ①Rebar planting method. When the main component is stressed, the longitudinally stressed steel bars and stirrups are dense, and it is difficult to drill holes. Smaller; ②The embedded steel frame method, the connection between the steel frame and the original concrete frame is more complicated, the operation is troublesome, and the amount of cast-in-place concrete and the welding of the steel frame are large, and the amount of steel is increased at the same time; ③The welding of the gusset plate and the outsourcing steel plate, The outsourcing steel plate conflicts with the wall and floor, making assembly difficult, and the amount of on-site welding is large, and the construction speed is slow

Therefore, the use of existing energy-dissipating supports and prefabricated concrete has complex on-site construction and low industrialization levels, which cannot reflect the characteristics of prefabricated structures.
