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

Abstract

The invention provides a lotus-root beam unit connected with a prefabricated floor slab unit and a three-dimensional beam-column unit. The unit includes a lotus-root beam body, a rebar material and anembedded part; the rebar material can be connected with a beam-unit rebar material in the three-dimensional beam-column unit through a sleeve, then concrete is poured, and the embedded part can be used for installing the prefabricated floor slab unit in place through a plate-beam installation hole in the prefabricated floor slab unit.

Description

technical field [0001] The invention relates to an assembled building component, in particular to an anti-falling off prefabricated floor unit. Background technique [0002] With the rapid development of my country's economy and society, the acceleration of urbanization, the increasing pressure on environmental governance, and the emergence 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 an increase Prefabrication rate of prefabricated buildings. The current industry standard "Technical Regulations for Prefabricated Concrete Structures" (JGJ-2014) provides the design requirements for the assembled integral frame structure. The assembled integral frame structure refers to the PC beam and column components connected in a reliable way and installed on site. Poured concrete, cement-based grouting material t...

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
