Description

Technical Field

[0001] The utility model relates to a formwork support structure for an inclined suspended formwork of a deformation joint, belonging to the technical field of deformation joint construction. Background Art

[0002] With the increasing number of high-rise buildings, in order to solve the uneven settlement caused by different building heights and structural forms, deformation joints are mostly set in the basement. The structures of deformation joints are diverse and relatively complex. One of the practices is to set a trapezoidal counter-camber at the deformation joint and embed a waterstop in the middle. Due to the complex structure and the inclined structure of the suspended formwork of the counter-camber, it is difficult to reinforce the suspended formwork. Therefore, the counter-camber of this type of deformation joint is usually cast in two times. However, the secondary casting of the counter-camber will form a construction joint, reducing the self-waterproofing ability of the structure and increasing the leakage risk at the deformation joint. Summary of the Utility Model

[0003] Based on the above, the utility model provides a formwork support structure for an inclined suspended formwork of a deformation joint, which solves the problems of difficult reinforcement, easy form bulging and poor appearance of the inclined suspended formwork, so as to achieve the one-time casting of the trapezoidal counter-camber of the deformation joint and the main structure, and improve the self-waterproofing ability at the deformation joint.

[0004] The technical solution of the utility model is: a formwork support structure for an inclined suspended formwork of a deformation joint, comprising:

[0005] A steel bar unit, which includes steel bars of a beam-slab structure and steel bars of a trapezoidal counter-camber, and the steel bars of the trapezoidal counter-camber are arranged on the steel bars of the beam-slab structure;

[0006] A formwork support unit, including positioning steel bars, an inclined suspended formwork steel bar frame, an inclined formwork and a vertical formwork. The positioning steel bars are welded to the steel bars of the beam-slab structure, and the positioning steel bars are arranged along the length direction below the hypotenuse of the steel bars of the trapezoidal counter-camber. The inclined suspended formwork steel bar frame is welded to the positioning steel bars. The inclined formwork is arranged on the hypotenuse of the steel bars of the trapezoidal counter-camber and is located inside the inclined suspended formwork steel bar frame. The vertical formwork is arranged on the vertical side of the steel bars of the trapezoidal counter-camber.

[0007] In one example, the inclined suspended formwork steel bar frame includes vertical steel bars, longitudinal steel bars, horizontal steel bars and diagonal steel bars. Multiple vertical steel bars are welded to the bottom of the longitudinal steel bars at intervals. Multiple horizontal steel bars are welded to the longitudinal steel bars at intervals. Multiple diagonal steel bars are welded to the longitudinal steel bars at intervals. Multiple vertical steel bars are welded to the positioning steel bars. The bottom of the inclined formwork is placed on the horizontal steel bars, and the outer side of the inclined formwork abuts against the diagonal steel bars.

[0008] In one example, inclined wooden squares are arranged outside the inclined formwork, vertical wooden squares are arranged outside the vertical formwork, triangular cushion woods are arranged on the inclined wooden squares, and tension-resistant waterstop screws are installed between the triangular cushion woods, the inclined wooden squares, the inclined formwork, the vertical formwork and the vertical wooden squares.

[0009] In one example, a waterstop is further provided on the steel bars of the beam-slab structure, and the waterstop extends a predetermined distance outward from the middle of the bottom surface of the trapezoidal inverted rib steel bars.

[0010] In one example, the waterstop is a buried rubber waterstop.

[0011] The beneficial effects of the utility model are as follows: by welding positioning steel bars on the steel bars of the beam-slab structure and welding an inclined formwork steel bar frame on the positioning steel bars, the positioning and fixing of the inclined formwork are realized by relying on the fixed support of the inclined formwork steel bar frame, positioning steel bars and beam-slab structure steel bars, effectively solving the problems of difficult reinforcement of the inclined formwork, easy form bulging and poor appearance, achieving the purpose of pouring the trapezoidal inverted rib at the deformation joint and the main structure at one time, improving the self-waterproofing ability of the structure at the deformation joint, and effectively reducing the risk of structure leakage.
