Background
In the installation of the template of the wall structure, the tension screw rod needs to be used for fixing and supporting. One of the commonly used counter-pulling screws is a three-section screw, which is composed of two outer rods, an inner rod and a conical nut.
Before the three-section type split screw is used, two separated outer rods and an inner rod need to be connected into a whole through split nuts. After the concrete construction is finished and before the formwork is dismantled, the outer rod is dismantled from the joint of the split nuts so as to be used again. In a construction site, due to the limitation of conditions, the conventional method is to manually connect or disconnect the screw threads by using a general-purpose tool such as a pipe wrench. The universal tool is not easy to clamp on the surface of the screw rod, and the screw thread connection pretightening force is not enough easily during screwing operation, so that the connection looseness and even the disconnection consequence are caused in the concrete pouring process, and the quality and the potential safety hazard are brought to template construction. And because the manual tool is adopted for operation, the working efficiency is lower, the workload is large, the tired emotion of an operator can be caused, and the quality control is not favorable.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve prior art not enough, provide a connection and split anchor clamps of syllogic screw rod that novel structure, safe and reliable, construction are convenient.
In order to achieve the purpose, the connecting and splitting clamp for the three-section screw rod comprises the three-section screw rod, an end cover, a gear wheel locking mechanism, a shifting ring assembly and a shell, wherein the shell and the end cover form a containing cavity, the gear wheel locking mechanism and the shifting ring assembly are arranged in the containing cavity, the gear wheel locking mechanism comprises a plurality of gear wheels, each gear wheel is provided with a pin hole, the shifting ring assembly is provided with a plurality of cylindrical pins, each cylindrical pin corresponds to the pin hole matched with one gear wheel, the shifting ring assembly can rotate to drive each gear wheel to rotate, and the middle of the gear wheel locking mechanism is opened or closed to lock the three-section screw rod.
The utility model discloses still have following preferred technical scheme:
1. the shell is provided with a notch which is matched with the ring shifting part of the ring shifting assembly to limit the rotation of the ring shifting assembly.
2. The front end of the end cover and the rear end of the shell are both provided with bosses which can be connected with a wrench.
Compared with the prior art, the utility model, its advantage lies in:
1. the device is simple to operate and convenient to use;
2. the working efficiency is improved;
3. the connecting device is used for connecting the outer rod and the inner rod, can improve the pretightening force of threaded connection, and improves the structural safety performance;
4. the application range is wide, and the three-section type split bolt connection and removal of different specifications can be met.

Detailed Description
The present invention will be further described with reference to the accompanying drawings, and the structure and principle of the present invention will be apparent to those skilled in the art. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The utility model relates to a connection and split anchor clamps of syllogic screw rod, including syllogic screw rod, end cover, gear wheel locking mechanism, dial ring subassembly and casing, casing and end cover component one hold the cavity, gear wheel locking mechanism and dial ring subassembly set up in holding the cavity, gear wheel locking mechanism comprises three gear wheel, all is equipped with the pinhole on every gear wheel, dial and be equipped with three cylindric lock on the ring subassembly, every cylindric lock corresponds the pinhole of a gear wheel of cooperation, is equipped with the notch on the casing, with dial the cooperation of the ring portion of ring subassembly, the rotation of ring subassembly is dialled in the restriction, dial the ring subassembly and rotate, drive every gear wheel and rotate, realize gear wheel locking mechanism middle part opening or close mouthful for locking syllogic screw rod, end cover front end and casing rear end all are equipped with the boss, can be connected with the spanner.
The working principle is as follows:
the special connecting and splitting clamp for the three-section screw rod is divided into a dismounting driving end and an installation driving end, and bosses at two ends can be connected and locked with a manual wrench or an electric wrench. When the dismounting driving end of the special clamp is connected with a spanner, a special dismounting tool is formed. When the mounting driving end of the special fixture is connected with a wrench, a special mounting tool is formed.
The cone locking mechanism is in a contraction state under the action of the torsion spring, and the screw cannot penetrate through the center of the special clamp. When the cone locking mechanism is used, the ring pulling assembly is manually rotated at first, the notch of the shell limits the rotation amplitude of the ring pulling assembly, the ring pulling assembly drives each cone to rotate, and the space opened in the middle of the whole cone locking mechanism is enough for a screw to penetrate through. At the moment, the central hole of the special clamp is sleeved on the outer rod of the three-section screw, the shifting ring is loosened, and the cone locking mechanism embraces the outer rod under the action of the torsion spring. Then the spanner is rotated, the gear wheel locking mechanism clamps the screw rod to drive the outer rod to rotate together, and the three-section type split screw rod can be installed and disassembled.
The specific operation process of the device is as follows by combining different requirements of installation and disassembly:
before the three-section screw is installed on a template, two outer rods and an inner rod need to be connected into a whole through nuts. Firstly, manually connecting the three-section type screw rods into a whole, connecting the installation driving ends of the special connecting and splitting clamp (the special clamp for short) of the three-section type screw rods with a socket wrench or an electric wrench, and assembling into the special installing tool for the split screw rods. And then fixing the inner rod, anticlockwise rotating a shifting ring on the special fixture, opening the gear locking mechanism, sleeving a central hole of the special fixture on the outer rod, installing a driving end outwards, loosening the shifting ring, clasping a screw rod by the gear locking mechanism, and then clockwise operating a wrench to tighten. And after the tightening is finished, the cone locking mechanism is unlocked by rotating anticlockwise, the shifting ring is manually rotated anticlockwise, and the special mounting tool is taken down.
After the wall structure formwork is dismantled, the three-section type split screw inner rod is fixedly connected with concrete, the outer rods at two ends are exposed in the concrete, and the outer rods need to be dismantled from the connection of the conical nuts. Firstly, the dismantling driving end of the special clamp is connected with a socket wrench or an electric wrench to assemble the dismantling tool special for the split screw. And then, clockwise rotating a shifting ring on the special fixture, opening a gear locking mechanism, sleeving a central hole of the special fixture into the outer rod, removing the outer rod with the driving end facing outwards, loosening the shifting ring, holding the screw rod by the gear locking mechanism, and then operating a socket wrench or an electric wrench anticlockwise to remove the outer rod. After the outer rod is disassembled, the outer rod is fixed, the shifting ring is rotated clockwise, and the special disassembling tool is taken down.
