Detailed Description
The invention is further described below with reference to the accompanying drawings. As shown in fig. 1 and 2, the main components of the present mounting device include: a threaded tube 1, an adjusting sleeve 3 and a screw 2.
The outer end of the threaded pipe 1 is fixedly connected with a hook, and the outer surface of the pipe body is provided with external threads.
The outer end of the screw rod 2 is fixedly connected with a hook, and the outer surface of the screw rod is provided with threads. The screw thread of the screw 2 is opposite to the external thread of the threaded pipe 1, i.e. if the surface of the threaded pipe 1 is a forward thread, the surface of the screw 2 should be designed as a reverse thread. The right port of the adjusting sleeve 3 has the same specification as the inner circle of the threaded pipe 1.
The pipe wall thickness of the two side end faces of the adjusting sleeve 3 is different, and the pipe orifice of the end face is opened according to the size of the part to be installed. The size of the pipe orifice at the left end of the adjusting sleeve 3 is matched with that of the threaded pipe 1, the pipe orifice at the left end is provided with a forward internal thread, and the outer wall of the threaded pipe 1 is provided with a matched forward thread; the size of the right end pipe orifice of the adjusting sleeve 3 is matched with that of the screw rod 2, the right end pipe orifice is provided with a reverse internal thread, and the surface of the screw rod 2 is a matched reverse thread. The opposite threads allow the threaded tube 1 and the screw 2 to be "extended" or "retracted" simultaneously as the adjustment sleeve 3 is rotated.
The inner diameter of the threaded pipe 1 is slightly larger than the outer diameter of the threaded rod 2, so that the condition that the threaded rod 2 and the threaded pipe 1 are opposite to each other in the adjusting sleeve 3 when the threaded rod and the threaded pipe are retracted is avoided, the central axes of the threaded rod 2 and the threaded pipe 1 are collinear, the threaded rod 2 can be inserted into the threaded pipe 1 when retracted, enough space is reserved in the threaded pipe 1, the movement of the threaded rod 2 is not influenced, and the normal use of the device is ensured;
after the tool is formed, the threaded pipe 1 and the screw rod 2 are respectively installed into the adjusting sleeve 3 from two sides, the adjusting sleeve 3 is designed to be used for adjusting the extension or contraction length of two ends, therefore, the threaded structures of the two sides are opposite threads, and the threaded pipe 1 and the screw rod 2 can synchronously enter or exit when the adjusting sleeve 3 rotates.
Further, the handle 4 is fixedly connected to the outer part of the adjusting sleeve 3, the handle 4 can be made of straight steel pipes, and two sections of straight steel pipes are symmetrically welded on the outer wall of the adjusting sleeve in a direction perpendicular to the axis of the adjusting sleeve.
The length and the diameter of all the rods of the tool can be adjusted and changed according to the actual wall thickness of a construction site. Taking a wall body with the thickness of 800mm as an example, preferably, the threaded pipe 1 is made of a seamless steel pipe with the outer diameter of 42mm, the wall thickness of 6mm and the length of 300mm, so that the strength of the pipe wall can be ensured by throwing after the pipe wall is threaded. Preferably, the adjusting sleeve 3 is made of a seamless steel pipe with an outer diameter of 60mm, a wall thickness of 6mm and a length of 300 mm. Preferably, the screw 2 is made of round steel with a diameter of 22 mm. Preferably, the outer handle 4 of the adjusting sleeve is made of steel pipes with the diameter of 20mm, the wall thickness of 3mm and the length of 200 mm.
Preferably, the length of the threaded tube 1, the screw rod 2 and the adjusting sleeve 3 is 1:1:1, and the length is set to be one half of the linear distance between two ends of the steel bar drag hook. The length of the outer handle 4 of the adjusting sleeve is set in combination with the mesh size of the wall steel bars to facilitate the device to be taken out from the wall steel bars as a reference after the installation is completed.
The method for installing the steel bar drag hook by adopting the tool is as shown in fig. 3 and 4:
1) After binding the reinforcing steel bars of the wall body, bending two ends of the S-shaped drag hook into 135-degree angles;
2) The whole length of the tool is adjusted to enable the distance between hooks at two ends to be larger than the distance between two reinforcing steel meshes;
3) Before the S-shaped drag hook is ready to be installed, the two ends of the device are hooked on the net sheet, and the lower hook is positioned near the position where the S-shaped drag hook is needed to be hung;
4) The adjusting sleeve 3 is rotated, the threaded pipes 1 and the threaded rods 2 at the two ends are contracted, the hooks tighten the reinforcing steel bar net 5 to enable the middle to bend inwards, and when the distance between the bending parts of the reinforcing steel bar net 5 is smaller than or equal to the distance between the two end points of the S-shaped drag hook 6, the operation is stopped;
5) The S-shaped drag hook 6 is hung on the reinforcing steel meshes 5 at two sides, then the hooks at two ends are reversely loosened, and the S-shaped drag hook is continuously installed at the next position after the tool is disassembled.
According to the invention, the mesh steel bars of the wall body are pulled close by utilizing the thread biting force, so that the installation of the steel bar drag hook is convenient, the two ends of the steel bar drag hook are bent in place before the installation, no personnel are required to separately arrange to bend the steel bar drag hook for the second time, the installation quality of the drag hook can be ensured, the standard and design requirements are met, the time and the labor are saved in the installation process, the pulling force is stable, the reworking cost is saved, and the resource utilization rate is improved.
