Embodiment 1

[0039] as attached Figure 1-Figure 6As shown, it is a template reinforcement tool, which includes a jacking 1 and a special fastener 2. The jacking 1 includes a screw A3 with external threads and a special nut 4 threaded with the screw A3. The outer wall of the special nut 4 is provided with a plurality of rocker holes 8 into which a rocker can be inserted, and one end of the screw rod A3 is fixed with a U-shaped supporting plate 6 . The special fastener 2 includes a semicircular fastener 10 and a semicircular fastener 2 14 rotatably connected together at one end through a rotating shaft 9, and the fastener 10 and the fastener 2 14 are fastened in the middle Formed as a circle, the other ends of the first fastener 10 and the second fastener 14 are connected by bolts, and a fastener arm 12 is fixedly connected to the outside of the fastener one 10, and the fastener arm 12 is along the fastener one 10 The radial setting of the fastener arm 12 is provided with a screw hole 11 ....

Embodiment 2

[0046] like Figure 1-Figure 8 Shown, a kind of method that utilizes the formwork reinforcement tool described in embodiment 1 to carry out the method for shear wall end formwork reinforcement, it comprises the steps:

[0047] (1) First use steel pipes, wooden squares, pull bolts 20, and 3-shaped clips 19 to support and reinforce the formwork on the front and rear sides of the end of the shear wall according to the general technology. The formwork is reinforced by setting two rows of horizontal steel pipes outside the formwork, and several The wooden square is reinforced by using 3-shaped clips 19 and pull bolts 20, and at the same time supporting the formwork of the end face of the shear wall, which is used to reinforce the upper horizontal steel pipe 21 of the front side formwork of the end of the shear wall. Neither the row of steel pipes (or the lower row of steel pipes) nor the upper row of steel pipes (or the lower row of steel pipes) used to reinforce the rear horizonta...

Embodiment 3

[0053] like Figure 1-Figure 6 and Figure 9-Figure 11 Shown, a kind of method that utilizes the formwork reinforcement tool described in embodiment 1 to carry out the method for formwork reinforcement of large sun angle position, it comprises the following steps:

[0054] (1) Use steel pipes, wooden squares, pull bolts 20, and 3-shaped clips 19 to support and reinforce the formwork on both adjacent sides of the big sun angle according to the general technology. Square, using 3-shaped clips 19 and pull bolts 20 for reinforcement, which is used to reinforce the horizontal steel pipe 28 of the adjacent side of the large positive angle and the horizontal steel pipe 27 of the adjacent side of the large positive angle of the two adjacent sides of the formwork, The upper or lower row of steel pipes in the two rows of horizontal steel pipes on one side intersect with the lower or upper row of steel pipes in the two rows of horizontal steel pipes on the other side to protrude from th...

Abstract

The invention discloses a formwork reinforcing tool and a method for reinforcing an external corner formwork through the same, and belongs to the technical field of building construction. According to the technical scheme, the formwork reinforcing tool comprises a jack and a special buckling piece. The jack comprises a lead screw A with an external thread and a special nut which is in threaded connection with the lead screw A, a plurality of rocker holes into which rockers can be inserted are formed in the outer side wall of the special nut, and a U-shaped supporting plate is fixed to one end of the lead screw A; the special buckling piece comprises a first semicircular buckling piece body and a second semicircular buckling piece body, wherein one end of the first semicircular buckling piece body is rotationally connected with one end of the second semicircular buckling piece body through a rotating shaft, the other end of the first buckle piece body is connected with the other end of the second buckling piece body through a bolt, a buckling piece arm is fixedly connected outside the first buckling piece body and arranged in the radial direction of the first buckling piece body, and a screw hole is formed in the buckling piece arm. According to the formwork reinforcing tool and the method, the special-design formwork reinforcing tool is adopted in cooperation with the universal reinforcing technology, the traditional external-corner-formwork supporting method is changed into a pulling-tying mode, pulling-tying prestress is generated accordingly, and the external corner formwork is firmly reinforced.

Description

technical field [0001] The invention relates to a formwork reinforcement tool, in particular to a tool for external corner formwork reinforcement, and belongs to the technical field of building construction. The present invention also relates to a method of using the formwork reinforcement tool to reinforce the external corner formwork Background technique [0002] The current general technology for strengthening the external corner formwork of the cast-in-situ concrete shear wall is generally as follows: 1. First, set up the wall formwork on the two adjacent sides of the external corner of the shear wall and reinforce it; 2. Use fasteners (general tools) at the external corner of the shear wall ) Connect the wall formwork on the two adjacent sides of the external corner with steel pipes; 3. Use step-by-step tightening and wooden wedges to fasten the external corner formwork. Due to the unreliable reinforcement of the external corner formwork in the above method, problems s...
