Description

Tool for cleaning mortar on surface of bolt thread

Technical Field

The utility model relates to a device that screw rod screw thread dirt was clear away, concretely relates to instrument of clearance bolt screw thread surface mortar.

Background

In industrial and civil buildings, anchor bolts are widely used for parts such as component installation, equipment foundations and the like, and since bolts (except sleeves) are basically all placed before concrete pouring, if bolt screw threads are not well protected or a protective object is damaged and falls off in the concrete pouring process, the screw threads are easily contaminated by mortar of the concrete, and if the mortar is not cleaned in time, the normal use of the bolts is affected. The most applied method in the existing bolt mortar cleaning method is to manually brush off the mortar by using a steel wire brush, and the method has low working efficiency and high labor cost.

SUMMERY OF THE UTILITY MODEL

Aiming at the defect that the foundation bolt in the prior art is contaminated by concrete mortar and cannot be normally used, a tool for cleaning the mortar on the screw thread is provided.

In order to achieve the above object, the present invention provides a screw thread mortar cleaning tool, which comprises:

a tool for cleaning mortar on the surface of a bolt thread is a pincer-shaped workpiece formed by intersecting a shear rod A and a shear rod B, a rivet is arranged on an intersection point, the shear rod A and the shear rod B in the front of the rivet are tong heads, the shear rod A and the shear rod B in the rear of the rivet are tong handles, and internal threads are arranged on the inner side of the tong heads.

Preferably, the tooth tip of the internal thread of the binding clip is smaller than the tooth mouth of the screw thread of the foundation bolt.

Preferably, the surface of the tooth point of the internal thread is provided with a rough top surface.

Preferably, the clamp handle ends of the shear rod A and the shear rod B are provided with a drawknot mechanism, and the shear rod B is provided with a mounting hole; the drawknot mechanism comprises a tension spring, a protruding needle, a limiting block and a small pressure spring; one end of the tension spring is fixedly connected with the shear rod A, and the other end of the tension spring is fixedly connected with the protruding needle; the protruding needle is provided with teeth and penetrates through the shear rod B; the limiting block is arranged in the shear rod B, limiting teeth are arranged on the lower sides of the limiting teeth, and the limiting teeth are meshed with the teeth; the small pressure spring is installed on the upper side of the limiting block, and the side face of the limiting block is also provided with a pulling head protruding out of the shearing rod B.

The tool is simple in structure, capable of quickly cleaning all mortar on the surface of the bolt thread, simple and easy to operate, convenient to operate, capable of greatly improving labor productivity and saving cost.

Detailed Description

The invention relates to a bolt mortar cleaning technology, which is applied to the field of building construction, and the invention is explained in detail by referring to the accompanying drawings 1-3 and the embodiment:

a tool for cleaning mortar on the surface of a bolt thread is a pincer-shaped workpiece formed by intersecting a shear rod A and a shear rod B, a rivet is arranged on an intersection point, the shear rod A and the shear rod B at the front part of the rivet are tong heads 1, the shear rod A and the shear rod B at the rear part of the rivet are tong handles 2, and inner threads 3 are arranged on the inner side of the tong heads 1.

The internal thread tooth point 11 of the tool bit provided by the invention is smaller than the tooth mouth 41 of the screw thread of the foundation bolt 4, and the tooth point 11 of the internal thread 3 pricks on mortar when the two threads are meshed.

Further, as shown in fig. 4, the surface of the internally threaded tooth point 1 is provided with a rough top surface.

Further improvements to the above tool: as shown in fig. 5 and 6, the ends of the handles of the shear bar a and the shear bar B are provided with a drawknot mechanism, and the shear bar B is provided with a mounting hole 21; the drawknot mechanism comprises a tension spring 61, a protruding needle 62, a limiting block 65 and a small compression spring 64; one end of a tension spring 61 is fixedly connected with the shear rod A, and the other end is fixedly connected with the protruding needle 62; the protruding needle 62 is provided with teeth 63, and the protruding needle 62 penetrates through the shear rod B; the limiting block 65 is installed in the shear rod B, a limiting tooth 67 is arranged on the lower side of the limiting tooth 67, and the limiting tooth 76 is meshed with the tooth 63; the upper side of the limiting block 65 is provided with a small pressure spring 64, and the side surface of the limiting block 65 is also provided with a pulling head 66 protruding out of the shearing rod B.

With reference to FIG. 2, the method for screw thread mortar cleaning using the above tool for cleaning surface mortar of bolt screw thread: if a worker holds the tool by hand, clamps the bolt by using the tong head with force, rotates the tool in the direction indicated by the arrow in fig. 2, and simultaneously enables the tool to move from the upper part to the lower part of the bolt screw thread, the purpose of cleaning mortar can be achieved.

The method for cleaning bolt mortar provided by the invention is simple and easy to implement, is convenient to operate, can greatly improve the labor productivity, can save the cost, and can completely clean the mortar on the surface of the bolt screw thread.
