Description

Wet joint reinforcing bar correcting unit

Technical Field

The utility model relates to a reinforcing bar correcting unit, especially a wet seam reinforcing bar correcting unit.

Background

After the bridge deck precast slabs are installed, longitudinal and transverse steel bars of two adjacent precast slabs need to be welded so that the bridge deck slabs are connected into a whole and stressed cooperatively. Due to objective reasons in all aspects, the distance between thick steel bars at the wet joint is large, and the steel bars cannot be welded. Therefore, the thick steel bars need to be corrected through external force, and the thick steel bars can be welded only when two adjacent steel bars are close to each other. The traditional correction method is to use a chain block or a steel chisel to correct the thick steel bars manually. However, the conventional method has the following problems: 1. all work is completed through manpower, and welding efficiency is slow, causes the time limit for a project to delay easily. 2. If the project progress needs to be accelerated, more personnel and equipment need to be equipped, so that the economic cost is greatly increased, and the risk occurrence probability is increased. 3. Workers sometimes can directly carry out heat treatment on the crude steel bars by oxygen and acetylene for convenience of drawing in the working process, and the structure and the performance of the steel bars can be easily damaged. To sum up, the traditional correction mode has the defects of large manpower consumption, long working time, low working efficiency, large destructiveness on the thick steel bars, high construction cost, certain potential safety hazards and the like.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

The embodiment of the utility model provides a: a wet joint reinforcing steel bar correcting device is shown in attached figures 1-3 and comprises a frame 2, wherein the top of the frame 2 is fixedly provided with 1 electric hoist 1, after a steel wire rope 4 on the electric hoist 1 is wound on a steering pulley 3, the other end of the steel wire rope 4 is fixedly connected with a steel plate clamp 5.

In use, the diverting pulley 3 and the steel plate clamp 5 are placed on the sides of the steel reinforcement 11 whose wet joint is to be corrected, respectively, and the diverting pulley 3 is fixed, as described in connection with fig. 2-3. After the diverting pulley 3 is fixed, the steel wire rope 4 can rotate around the diverting pulley 3 to receive and release the steel plate clamp 5, so that the working stroke range of the device is enlarged. The steel wire rope 4 is steered and adjusted through the steering pulley 3, so that the arrangement direction of the steel wire rope 4 between the steering pulley 3 and the steel plate clamp 5 is parallel to the arrangement direction of the steel bars 11 to be corrected. The contact surface of the steel plate clamp 5 and the steel bar 11 to be corrected is adjusted, so that the steering pulley 3 and the steel plate clamp 5 can be attached to the steel bar 11 to be corrected of the wet joint to the maximum extent, and the steel bar 11 to be corrected can be stressed well. The electric hoist 1 on the upper portion of the frame 2 is started, the steel wire rope 4 is tightened, the steel wire rope 4 pulls to tighten the steering pulley 3 and the steel plate clamp 5, the side face of the steel plate clamp 5 generates horizontal extrusion force to the steel bar 11 to be corrected in the process of tensioning and rotating, and the distance between the steel bars 11 to be corrected is reduced under the action of the extrusion force until the distance meets the welding requirement.

After welding is completed, when the device needs to be moved to the next working surface, the walking steel plate 8 needs to be erected at the wet joint, so that the device can span the wet joint, and the device is convenient to move.

The steel plate clamp 5 is of a Z-shaped structure, the steel plate clamp 5 of the structure is placed as shown in the attached drawings 2-3, the steel plate clamp 5 in the shape can simultaneously correct the upper layer and the lower layer of the steel bars 11 to be corrected at the wet joint position in the using process, and the welding efficiency of the steel bars is accelerated.

The other end of the steel wire rope 4 is connected with the steel plate clamp 5 through a shackle 9 and a round steel pull ring 10, and after the steel plate clamp 5 is pulled and deformed for a long time, the shackle 9 is opened, and then the steel plate clamp 5 can be replaced by a new steel plate clamp 5. A round steel pull ring 10 is welded on the steel plate clamp 5, and is conveniently buckled with the shackle 9.

The supporting legs on the periphery of the bottom of the frame 2 are respectively provided with 1

universal wheel

7 and 1 nut, and 1 screw steel 6 is screwed into the middle thread of each nut. In the whole working process of the device, the screw steel 6 arranged on the supporting legs of the frame 2 is placed on the ground and screwed down, so that the effect of braking is achieved, and the correction effect cannot be influenced by shaking of the device. After the steel bar is welded, the screw steel 6 is lifted, and the device can move on the bridge deck. The screw steel 6 is connected with the frame 2 through nuts welded on the four supporting legs, and the movement and the stability of the control device are controlled. The universal wheels 7 are arranged, so that the device can move freely and change working surfaces quickly.

When the steel plate clamp 5 is used for correcting the thick steel bars, the length of the steel plate clamp 5 is not too long, so that the steel plate clamp 5 can be easily taken out of the thick steel bars.

The diverting pulley 3 is provided with a hook 12, and the steel bar 11 to be corrected is hooked by the hook 12, so that the diverting pulley 3 is fixed.

The frame 2 is of a frame structure and is made of section steel, so that local materials are convenient to use.

The steel plate clamp 5 and the diverting pulley 3 are brought into contact with the reinforcement 11 to be corrected before the correction is started with the contact surface with the reinforcement 11 to be corrected as large as possible. Therefore, the shapes of the steel plate clamp 5 and the steering pulley 3 are considered during design, and the linear radian of the contact surface of the steel bar 11 to be corrected is better, so that the steel bar 11 to be corrected can be better attached.
