The utility model content
The purpose of this utility model is to provide a kind of large-tonnage from the spandrel girder ruggedized construction of the tower crane attached wall built-in fitting that climbs, solve the concrete beam structure and adopt the shaped steel outsourcing, the shortcoming such as the site operation that steel plate exists during the method for the structure external reinforcement such as sticking outward is complicated, installing/dismounting is inconvenient, expend great deal of steel, the reinforcing expense is higher.
For achieving the above object, the utility model adopts following technical scheme:
a kind of large-tonnage is from the spandrel girder ruggedized construction of the tower crane attached wall built-in fitting that climbs, comprise and being arranged in Core Walls Structure, upper strata coupling beam between the shear wall of both sides and lower floor's coupling beam, be equipped with vertical muscle and stirrup in beam, also be provided with the attached wall built-in fitting in lower floor's coupling beam, between described upper strata coupling beam and lower floor's coupling beam, the Si Jiaochu of attached wall built-in fitting is arranged with steel tie between the beam of vertical two ends band crotch, described crotch is parallel with coupling beam and point to the center of attached wall built-in fitting, between beam, the crotch at steel tie two ends is imbedded respectively among upper strata coupling beam and lower floor's coupling beam, in the beam of described upper strata coupling beam and lower floor's coupling beam, two ends also are provided with the reinforcing bent-up bar.
Between described beam, steel tie divides two sections, and segmentation place is positioned at the upper surface of lower floor's coupling beam and uses reinforced bar sleeve to connect.
Described reinforcing bent-up bar is two grade reinforcing steels that are not less than diameter 28mm, and the length of its horizontal anchoring section equals original vertical muscle length in coupling beam.
Compared with prior art the utlity model has following characteristics and beneficial effect:
The utility model is to satisfy large-tonnage from the requirement for bearing capacity of the tower crane that climbs, and adopts to increase in spandrel girder and joins beam-ends reinforcing bent-up bar, and main structure body is not exerted an influence, and saves the dismounting operation, saves manpower; Between the two-layer spandrel girder in up and down, steel tie between beam is set, engineering is cut off after finishing, and the reinforcing bar that cuts off is also recycling.The advantages such as the utility model only adopts steel reinforcing to be convenient to draw materials, and has constructing operation simple, and is safe and reliable efficient, economical and practical.
