Assembly type concrete frame structure beam column rigidity connection node

Abstract

The invention discloses an assembly type concrete frame structure beam column rigidity connection node. The connection node comprises a frame beam, a frame column and a beam column rigidity connection node body; a first steel plate is arranged on the end portion of the frame beam, a second steel plate and a third steel plate are arranged on two sides of the frame column, and the second steel plate is connected with the third steel plate through rebars in a second pre-buried part; the beam column rigidity connection node body comprises an H-shaped steel, the first steel plate is connected with the second steel plate through the H-shaped steel, and the connection of the frame beam and the frame column is achieved. According to the assembly type concrete frame structure beam column rigidity connection node, through the external H-shaped steel, assembly type concrete frame structure beam columns are connected, the complexity of beam column connection is greatly simplified, the H-shaped steel is not located in concrete of a precast beam and is connected with anchor bars in the beam through an end plate; the H-shaped steel is directly connected with the cylinder-edge end plate in a stud welded mode, the connection node of a steel structure is directly applied to a precast concrete component, the construction process is simplified, the construction speed is improved, the beam column positioning is more precise, and the connection node provides convenience for the following structure construction.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a beam-column rigid connection node of an assembled concrete frame structure. Background technique [0002] With the rapid development of my country's economy, people's living standards are constantly improving, and the requirements for buildings are increasing; at the same time, the cast-in-place construction method of buildings is not compatible with the concept of sustainable development in my country. At present, my country urgently needs to solve the problems of high energy consumption, high pollution, and high investment in residential construction. Therefore, the Ministry of Housing and Urban-Rural Development of the Development and Reform Commission of my country has promulgated the "Green Building Action Plan", which clearly mentions the promotion of prefabricated assembly suitable for industrial production Concrete structure, steel structure and other bu...

Problems solved by technology

[0006] However, prefabricated concrete structures also have some disadvantages of their own, such as complex joint connections

The current main connection node form requires on-site binding of steel bars, pouring of concrete, and scaffolding, formwork, etc., which brings hidden dangers to the quality of the joints, requires high construction technology, and limits the use of precast concrete components to a certain extent.
