Description

TECHNICAL FIELD [0001] The present invention relates to a concrete laitance removing device and a concrete laitance removing method using the same. BACKGROUND ART [0002]

The present invention relates to a concrete rattens removing apparatus and a concrete using apparatus for removing concrete from the concrete surface, which can improve the removal efficiency of the concrete by thoroughly removing the rattens by strongly scraping the surface of the concrete with the cylindrical metal brush, To a method for removing latency.

Generally, laitance is a phenomenon caused by a phenomenon of bleeding when concrete is poured, and when another concrete is laid again without removing the latency, a bonding failure occurs at the interface of the concrete do.

Therefore, in order to solve this problem, conventionally, the worker manually removed the latency by a hand brake or sprayed high-pressure water using a water jet to remove the laitance from the concrete surface.

However, in the case of manual work using the hand brakeer, only the portion of the concrete where the hand brake is contacted is deeply recessed, so that the foreign matter (water, sawdust, sand, soil, etc.) In addition, since the latency is removed only at the portion where the narrow end portion of the hand brake is touched, there is a problem that the working time is very long in order to remove the latency as a whole.

In addition, there is a problem in that, when a worker is required to hold the lower part of the hand brake, the form is installed and the space is narrowed, the elimination of the latency is practically impossible. In addition, after removing the latency by the hand brake, In addition, when the concrete is poured on the concrete in a state where the water is not completely drained, there is a problem that the quality of the concrete is deteriorated by the water.

In addition, water jets are also required to have a large water pressure, and water is severely scattered around the worksite, which makes the workplace dirty. Also, the method of removing the water by the water jet must be performed within 24 hours after the concrete is poured, .

In addition, there is a problem in that the surface is irregularly scratched due to the high-pressure jetting and the surface is irregular. As a result, the water remains in the dented portion after the operation so that the latent or foreign matter remains, The water is not completely drained and the concrete quality is deteriorated.

In order to solve this problem, in Patent Document 1, a diaphragm having concave and convex portions formed on the lower end surface thereof and a perforated hole at its center is connected to a hollow tube so that the hollow tube and the through hole are connected to each other, and the hollow tube is connected to the suction hose A hollow tube is provided with a vibrator and a switch for driving the vibrator, thereby removing the latency by the diaphragm, and simultaneously introducing the dust into the suction hose through the suction hose.

However, in the case of Patent Document 1, since the latency is not physically removed by the diaphragm alone, the removal efficiency is extremely low. In addition, since the operator still has to perform the removal process manually by carrying the device, it takes a long time There was a problem.

In addition, dust generated due to the removal of laitance is not generated only in one direction but scattered in all directions. Therefore, dust removal efficiency is insufficient only by the suction hose, and when the concrete to be removed is moved or discharged, There is a problem that unnecessary damage occurs.
