In the later secondary structure construction, the longitudinal reinforcement is bent horizontally and welded with the embedded iron at the bottom of the upper beam to realize the connection between the structural column and the upper beam.
Indoor functions: two rooms, two bathrooms, one kitchen and two hall on the first floor, three rooms, three bathrooms, two balconies and one hall on the second floor, three rooms, two bathrooms and one balcony on the third floor.
In order to meet the requirement that the structural bending in the villa effect drawing does not limit the relative deformation of upper and lower beams, when the structural column concrete is poured to the beam bottom, cement mortar is used to replace the main frame beam bottom.
Indoor functions: two halls on the basement, one garage, one balcony, one laundry room, one film and television hall, one room, three halls, two bathrooms, one cloakroom, two balconies, three rooms, one hall, three bathrooms, two balconies, one book on the second floor, three rooms, three bathrooms, four balconies, and one study on the third floor..
The spacing of stirrups in the overlapping area shall not be greater than to realize the connection between the constructional column and the near beam.
D is the diameter of the longitudinal reinforcement of the structural column.
The third set: embedded parts should be placed at the top of the structural columns on each floor and at the bottom of the beam or slab of the main structural frame (non frame).
Indoor functions: The following is the introduction of the house type on the right: an underground garage with one bathroom and three halls, a first floor with one room, two bathrooms, one kitchen, two halls and one balcony, a second floor with two bathrooms, two bathrooms, one study with one hall and one balcony, a third floor with two rooms, two bathrooms, two bathrooms, one balcony and one study with one balcony.
In this way, when the upper and lower beams are relatively deformed, the top of the constructional column has certain compressibility, which will not affect the relative deformation of the upper and lower beams.
The welding length of single side welding should not be less than D, and the welding length of double side welding should not be less than D.
The overlapping length of structural column open joint reinforcement and longitudinal reinforcement shall be indicated by the designer in the general description of structural design.
