Embodiment 1

[0024] as attached Figure 1-Figure 6 As shown, it is a template reinforcement tool, which includes a jacking 1 and an O-shaped card 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 O-shaped clip 2 includes an O-shaped sleeve 10, which can be set on the steel pipe used to reinforce the template. A rectangular plate-shaped clamping arm 9 is fixedly connected to the outer wall of the O-shaped sleeve 10, the O-shaped sleeve 10 is arranged parallel to the width direction of the clamped arm 9, and the clamped arm 9 is placed on the Both radial sides of the O-shaped sleeve 10 have outwardly extending ends respectively. A screw hole 11 is provided on one of the extending ends of the locking arm 9 , and the length of the other ...

Embodiment 2

[0030] Such as Figure 1-Figure 8 Shown, a kind of method that utilizes the formwork reinforcement tool described in embodiment 1 to carry out wall stack formwork reinforcement, it comprises the steps:

[0031] (1) First, use steel pipes, wooden squares, pull bolts 15, and 3-shaped clips 17 to support the front and rear sides of the wall stack, the formwork 12 on the end face of the wall stack, and the adjacent wall formwork 21 according to the general technology, and the formwork is reinforced on the outside of the formwork Set up two rows of horizontal steel pipes and several wooden squares, and use 3-shaped clips 17 and pull bolts 15 to reinforce them. The upper row of steel pipes (or the lower row of steel pipes) used to reinforce the front horizontal steel pipes 18 of the wall stack front formwork And the upper row of steel pipes (or the lower row of steel pipes) of the horizontal steel pipes 22 on the rear side of the wall stack that are used to reinforce the formwork at...

Abstract

The invention discloses a template reinforcing tool and a method for reinforcing a wall pier template by using the template reinforcing tool, and belongs to the technical field of building construction. The technical scheme is that the temperature reinforcing tool comprises jackings and an O-shaped clamp, wherein each jacking comprises a screw rod A with external threads and a special nut which is in threaded connection with the screw rod A; a plurality of rocker holes for inserting rockers are formed in the outer side walls of the special nuts; a U-shaped supporting plate is fixedly arranged at one end of each screw rod A; the O-shaped clamp comprises an O-shaped sleeve; the outer side wall of the O-shaped sleeve is fixedly connected with a rectangularly flat clamping arm; the O-shaped sleeve is arranged in a manner of being parallel to the width direction of the clamping arm, and the clamping arm 9 is provided with extending ends towards two radial sides of the O-shaped sleeve 10; a screw hole is formed in one extending end of the clamping arm; and the length of the other extending end of the clamping arm is greater than the diameter of the O-shaped sleeve. According to the template reinforcing tool with special design, by the combination of a general reinforcing technology, a conventional external corner supporting method is changed into a tying mode, so that an external corner template can be reinforced firmly.

Description

technical field [0001] The invention relates to a formwork reinforcement tool, in particular to a tool for wall stack formwork reinforcement, and belongs to the technical field of building construction. The invention also relates to a method for reinforcing a wall stack formwork by using the formwork strengthening tool. 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 such as mold runn...
