Novel fabricated beam joint and construction form thereof

Abstract

The invention discloses a novel fabricated beam joint and a construction form thereof. The novel fabricated beam joint comprises a prefabricated main beam and cast-in-place ultrahigh-performance concrete. Bolt holes are reserved in the bottom and the bevel of the prefabricated main beam, the bolt holes are in penetrating connection in an upper hole and a lower hole in the prefabricated main beam.The vertical faces of the two sides of the prefabricated main beam are concave-convex faces, and U-shaped steel bars and stretching-out steel bars are reserved. In the prefabricated main beam, high-strength bolts penetrate through the four bolt holes in the vertical direction, finally the prefabricated main beam is fixed to an anchoring part on the beam surface to be connected with the anchoring part, the U-shaped steel bars and the stretching-out steel bars are used for connecting in the horizontal direction, namely, the concave-convex faces, and finally the cast-in-place ultrahigh-performance concrete is used on two main beam seams to achieve binding. The beam joint adopts the connecting manner of combining dry connecting and wet connecting, the advantages of the two connecting manners are achieved at the same time, the novel fabricated beam joint has the advantages of good integrity, ductility, anti-seismic property and the like, meanwhile, the assembly rate is relatively improved,and more efficient and energy-saving development of a fabricated building is promoted.

Description

technical field [0001] The invention relates to the technical field of prefabricated beams, in particular to a novel prefabricated beam node and its construction form. Background technique [0002] The construction and assembly of prefabricated buildings have a high degree of mechanization, which greatly reduces the wet operations such as mixing mud, plastering, and building walls on site, and greatly shortens the construction period; it can greatly reduce the discharge of construction waste and wastewater, which is conducive to the healthy and green development of cities in our country. At the same time, it has significant advantages such as resource saving, green energy saving and environmental protection, and good performance indicators, which is also the development trend of the modern construction industry. [0003] In the actual engineering of prefabricated building nodes, wet connection is the main method. This connection means that the main bars and structural steel ...

AI Technical Summary

Problems solved by technology

However, the interface connection method is too single, the integrity is poor, and it lacks multiple connection protection methods

[0005] The combination of dry connection and wet connection is relatively rare, and its performance can take into account the advantages of both, but related technologies are relatively lacking
