Definitions

  • the invention relates to an assembly type building component, in particular to an anti-falling prefabricated floor slab unit.
  • the design rule of a common composite floor slab is given by the existing industry standard ‘prefabricated concrete structure technical regulation’ (JGJ-2014), and the fully prefabricated floor slab is used for a fully-fabricated building, namely a dry-method assembled building, and can be only applied to non-seismic or low-seismic fortification intensity engineering due to the poor seismic performance of the current fully-prefabricated floor slab. Therefore, in order to improve the prefabrication rate of the fabricated building and ensure the seismic fortification capacity, designing a full-prefabricated floor slab with excellent seismic performance becomes an urgent technical problem to be solved in the industry.
  • the invention aims to provide a floor slab which is reasonable in structure and convenient to install, can realize complete prefabrication, reduces the uncertainty and the complex process of cast-in-place, and directly installs an anti-falling prefabricated floor slab unit on an assembled three-dimensional beam-column unit in a mechanical connection mode, thereby greatly improving the prefabrication rate of an assembled building and ensuring excellent seismic fortification capacity.
  • the invention provides an anti-falling prefabricated floor slab unit, wherein, the prefabricated floor slab unit is provided with a slab-column mounting hole matched with a column unit in cross section; and the anti-falling prefabricated floor slab unit is provided with a slab-beam mounting hole which is connected with an embedded part on the top surface of a beam unit or/and a lotus root beam unit to mount the anti-falling prefabricated floor slab unit.
  • the anti-falling prefabricated floor slab unit adopting the technical scheme of the invention has the following characteristics: the anti-falling prefabricated floor unit is provided with a connecting member connected with the column unit and/or the beam unit; the connecting member provided on the anti-falling prefabricated floor slab unit is a vibration-isolation connecting member; the material of bottom of the connecting member is the same as a gasket of the embedded part of the beam unit between anti-falling prefabricated floor slab unit and the beam unit; and the lower part of the anti-falling prefabricated floor slab unit is provided with a prefabricated member connected with a post-pouring area between the beam unit and the beam unit or between the beam unit and the lotus root beam unit.
  • the bottom of the connecting member does not extend to the edge of the anti-falling prefabricated floor slab.
  • the bottom of the connecting member extends to the edge of the anti-falling prefabricated floor slab, and a mounting hole is arranged at the position of the embedded part of the beam unit and is matched with the embedded part.
  • the bottom of the connecting member is matched to the top surface of the beam unit.
  • the bottom of the connecting member is matched with the edge of the top surface of the beam unit.
  • the vibration-isolation connecting member is made of high polymer damping material.
  • the vibration-isolation connecting member is made of rubber material.
  • the invention has the following technical effects that the anti-falling prefabricated floor slab unit can be prevented from falling off under the working condition of mechanical installation, stress concentration is prevented between the anti-falling prefabricated floor slab unit and the three-dimensional beam column unit, the isolation performance is realized, the earthquake force is reduced, and the maximum horizontal displacement of a building and the interlayer horizontal displacement under the earthquake working condition are controlled.
  • the anti-falling prefabricated floor slab unit is designed so that the development of the fabricated building is greatly promoted, the prefabrication rate of the fabricated building is improved, convenience is provided for later installation projects, and various related social resources are saved.
