Concrete crack repairing auxiliary tool

Abstract

The invention relates to the technical field of concrete engineering, in particular to a concrete crack repairing auxiliary tool. A spray head is detachably connected with a cylinder body; a nut cap with a screw hole is arranged at the back end of the cylinder body; a push cake is arranged in the cylinder body; a bolt push rod passes through the screw hole of the nut cap and is fixedly connected with the push cake. The bolt push rod of the concrete crack repairing auxiliary tool rotates to be stressed, so that a repairing agent is uniform and labor-saving in injection molding; furthermore, thecylinder body can be filled with more slurry at one time, so that repairing is more convenient and continuous, and the injection molded slurry can be combined with fracture pores tightly and closely.Furthermore, the repairing auxiliary tool is simple and easy to operate, easy to clean, convenient to use and low in manufacturing cost, and has high practicability.

Description

technical field [0001] The invention relates to the technical field of concrete engineering, in particular to a concrete crack repair aid. Background technique [0002] Concrete occupies an important position in modern engineering construction. It is the most complex system produced by the simplest process. With many advantages such as good moldability and durability, it is not only used in various civil engineering, but also in the machinery industry, shipbuilding industry, and marine development. It is an important material. [0003] However, at present, a fairly common quality problem in concrete structures is the problem of concrete cracks, which are increasing day by day, but have not been eliminated repeatedly. Because the damage and collapse of concrete structures under the action of external loads all start from the expansion of cracks, so people Cracks often produce a sense of fear of building damage, which has affected normal life and production, which is not expe...

[0003] However, at present, a fairly common quality problem in concrete structures is the problem of concrete cracks, which are increasing day by day, but have not been eliminated repeatedly. Because the damage and collapse of concrete structures under the action of external loads all start from the expansion of cracks, so people Cracks often produce a sense of fear of building damage, which has affected normal life and production, which is not expected by those skilled in the art
