Embodiment Construction

[0044] The nodes of the present invention will be described in detail below in conjunction with the accompanying drawings. It mainly expounds that the post-cast section is active powder concrete and the shear connector is a prefabricated node with U-shaped steel bars.

[0045] See Figure 1-7 . The inventive joints include beam-beam joints and beam-column joints. The beam-beam joints include two protruding special-shaped beam ends, with active powder concrete cast in-situ in the middle, and two hoisting holes are respectively set at the two adjacent beam ends to facilitate hoisting. Beam-column joints include two structural forms: one overhanging special-shaped beam end and two overhanging special-shaped column ends, and the lower reinforcement at the two overhanging special-shaped beam ends. Pouring of reactive powder concrete or ordinary concrete. Reinforcement with concrete and two overhanging profiled column ends. Adjacent beam ends remain on the same line, and adjacen...

Abstract

The invention discloses a novel fabricated building joint and a construction form thereof. The novel fabricated building joint mainly comprises reinforcement, normal concrete or high-performance concrete or reactive powder concrete (RPC), and is characterized in that a special-shaped normal concrete structure factory is adopted to pre-embed U-shaped or T-shaped reinforcement, and stagger arrangement is carried out; and the reinforcement at the upper part and lower part adopts overlapped part reinforcement lap-jointing, welding, grouting or sleeve connection, and the RPC or normal concrete or high-performance concrete is poured at the post-casting section. The joint is suitable for beam-beam joint, beam-column joint and shear wall joint connection, and is excellent in stress form, the U-shaped reinforcement or T-shaped reinforcement is added, shear resisting performance is high, the interface contact area between old and new concrete is large, connection is reliable, the work efficiencyis improved greatly, and the length of reinforcement anchoring is also decreased, safety is high, adhesion is high, anti-seismic performance is good, and the novel fabricated building joint can be widely applied to prefabricated parts and has the advantages of being efficient in fabricated building and high in safety index.

Description

technical field [0001] The invention relates to a novel assembled building node, which belongs to the technical field of building structure design. . Background technique [0002] Prefabricated buildings are highly efficient and environmentally friendly, which greatly conforms to my country's sustainable development strategy and is conducive to achieving the goal of green environmental protection and low carbon. The scale of prefabricated buildings is gradually increasing, the traditional construction methods are subtly changed, and the relevant components are reasonably assembled, standardized and informatized, and the advantages of utilization are very obvious. [0003] In actual joint projects, it is often seen that concrete is poured on site at the joints to complete the connection of beams, columns, and floors. Generally, the steel bars at the joints are bent and anchored or welded, or both are used in combination to form a semi-fabricated structure. Although the qual...
