Embodiment 1

[0032] Such as Figure 1-6 As shown, a kind of self-unloading and adjustable pulling screw device includes a fixed-distance screw 3 in the middle and two positioning screws 1 at both ends of the fixed-distance screw 3. The fixed-distance screw 3 and the two positioning screws 1 pass through a sleeve respectively The barrel 2 is movably connected, and the positioning screw 1 is provided with a mountain-shaped card 5 and a mountain-shaped card fixing nut 4; the positioning screw 1 is provided with a square flat mouth section 6, and the mountain-shaped card 5 is provided with a connected square flat hole 8 And round hole 9; Locating screw rod 1 is penetrated by mountain-shaped card round hole 9, blocks its square flat mouth section 6 rotations by mountain-shaped card square flat hole 8 and installs, removes.

[0033] The sleeve 2 is provided with an internally threaded through hole, and the middle part of the internally threaded through hole is provided with a polygonal sleeve sc...

Embodiment 2

[0038] The method for disassembling and assembling the self-unloading adjustable pull screw device in the construction process described in Embodiment 1: includes the following steps:

[0039] 1) Apply the non-curing waterproof coating (such as rubberized asphalt non-curing waterproof coating) to the fixed-distance screw in the middle, and insert the fixed-distance screw and the sleeve in the middle on both sides of the construction formwork with threaded screws;

[0040] 2) The positioning screws at both ends are penetrated through the round holes of the mountain-shaped card;

[0041] 3) Install the positioning screw in the sleeves on both sides by clamping the square flat section of the positioning screw through the square flat hole of the mountain type card;

[0042] 4) During the construction process, the position of the sleeve is adjusted through a sleeve screw rod matching the screw hole of the sleeve, and the positions of the positioning screws at both ends are adjusted...

Abstract

The invention relates to a self-disassembled adjustable opposite-pull screw device and an assembling and disassembling method thereof. The self-disassembled adjustable opposite-pull screw device comprises a fixed-pitch screw in the middle, and positioning screws on two ends, wherein the fixed-pitch screw and the positioning screws are movably connected through a sleeve, a clip shaped like a Chinese character 'shan' and a clip set screw nut shaped like a Chinese character 'shan' are arranged on the positioning screws; a square flat-mouth section is arranged on each positioning screw, and a square flat hole and a circular hole which are communicated are formed in the clip shaped like a Chinese character 'shan'; the positioning screws penetrate through the circular hole of the clip shaped like a Chinese character 'shan', the assembling can be conducted by clamping the rotation of the square flat-mouth section through the square flat hole of the clip shaped like a Chinese character 'shan'; in disassembling, the clip set screw nut shaped like a Chinese character 'shan' is screwed down, the positioning screws can be disassembled from the sleeve by utilizing the clip shaped like a Chinese character 'shan', the sleeve can be screwed out anticlockwise through inserting a sleeve screwing lever into a sleeve screwing opening. The method and the device are convenient to disassemble, the loss of a template is reduced, the model disassembling time can be shortened, and the construction efficiency can be improved.

Description

technical field [0001] The invention relates to the field of pull screws used in building construction shear walls, in particular to a self-unloading adjustable pull screw assembly and disassembly method and device. Background technique [0002] In the construction of building structures, conventional pull screws include two positioning screws, a distance screw, and two sleeves. And the nut clamps and fixes the positioning screw rod and the template. After pouring and forming, the positioning screw that runs through the formwork needs to be unscrewed and removed. Since the positioning screw has a conventional thread and a centered hexagonal head section structure, when the positioning screw is screwed out, the corresponding tool must be used. The direct action of external force will make the positioning screw easy to be damaged and deformed. , which reduces the service life of the screw; in addition, the existing pull screw sleeve is either a full thread structure, or a pol...
