Constructional column slant split bolt and construction method of fixed formwork by using bolt

Abstract

The invention discloses a constructional column slant split bolt and a construction method of a fixed formwork by using the bolt. The slant split bolt comprises an A type split bolt and a B type splitbolt, the A type split bolt comprises a screw rod I, a screw cap I and two right-angle fixed parts I on the two ends of the screw rod I, and the B type A type split bolt comprises a screw rod II, a screw cap II and a right-angle fixed part II and a right-angle fixed part III on the two ends of the screw rod II. The construction method comprises the steps that after walls on the two sides of a constructional column are built, double faced adhesive tape is pasted along concave and convex joint openings of combed joints, a typified form is mounted, in the height direction, each layer of concavejoint is subjected to uniform and opposite-angle punching, pvc casing pipes are inserted, the screw rod or screw rod II of the slant split bolt is inserted, after finishing, the right-angle fixing parts I or the right-angle fixing parts II III are mounted on two ends or one end of the screw rod, and the screw cap I or the screw cap II is twisted. The split bolt has universality, the material circulation is high, the construction is rapid, convenient and efficient, and reinforcing is scientific and reasonable.

Description

technical field [0001] The invention relates to a fixing device and a construction process of a construction column formwork, in particular to a construction method for a construction column obliquely pulling bolts and fixing the formwork. Background technique [0002] At present, it is known that structural columns refer to reinforced concrete structural columns in the walls of multi-storey brick-concrete structures in order to enhance the integrity and stability of buildings, and to connect with ring beams on each floor to form a structure capable of resisting It is an effective measure to prevent houses from collapsing. Structural columns are installed at the four corners of the outer wall, at the junction of the horizontal wall and the outer longitudinal wall at the staggered level, on both sides of the larger opening, at the junction of the inner and outer walls of the large room, etc. The structural columns include rectangular structural columns set in the middle of t...

However, it is only reinforced by a short cable-stayed screw in one direction. If it is tightened, the male corner is prone to deformation and collapse; if it is loosened, it is prone to mold expansion and slurry leakage. Effective reinforcement, and only suitable for reinforcement at the corner of the concrete structure (ie L wall)
