Lotus-root-type beam unit connected with prefabricated floor unit and three-dimensional beam-column unit

Abstract

The invention provides a lotus-root-type beam unit connected with a prefabricated floor unit and a three-dimensional beam-column unit. The lotus-root-type beam unit comprises a lotus-root-type beam body, ribs and embedded parts. The ribs can be connected with beam unit ribs in the three-dimensional beam-column unit through sleeves, then concrete is poured, the embedded parts can make the prefabricated floor unit be mounted in place through plate-beam mounting holes in the prefabricated floor unit, the lotus-root-type beam unit is of a double-lotus-root form, and the section of the lotus-root-type beam body is rectangular.

Description

technical field [0001] The invention relates to a prefabricated building component, in particular to an anti-falling prefabricated floor unit. Background technique [0002] With the rapid development of my country's economy and society, the accelerated urbanization process, the increasing pressure on environmental governance, and the trend of labor shortages, the country has gradually put forward higher requirements for prefabricated buildings, requiring an increase in the proportion of prefabricated buildings in new buildings, and at the same time requiring higher The prefabrication rate of prefabricated buildings. The current industry standard "Technical Regulations for Prefabricated Concrete Structures" (JGJ-2014) gives the design requirements for prefabricated monolithic frame structures. Prefabricated monolithic frame structures refer to PC beams and column members that are connected in a reliable way and installed on site. Concrete is poured and the cement-based grouti...

Problems solved by technology

The current industry standard "Technical Regulations for Prefabricated Concrete Structures" (JGJ-2014) provides the design requirements for assembled integral frame structures. Assembled integral frame structures refer to PC beams and columns that are connected in a reliable way and installed on site. Pour concrete, cement-based grouting material to form a whole, that is, to form a whole with the so-called wet connection, the design is equivalent to cast-in-place, and the seismic requirements of the core area of ​​the assembled integral structure node are the same as that of the cast-in-place structure, which is completely composed of three-dimensional prefabricated beam-column units After the components are assembled, the components are poured, and the transportation is difficult due to the large components, which increases the difficulty of installation
