Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar rust removal, in particular to a pre-buried exposed steel bar rust remover. Background Art

[0002] During the construction process, steel bars will be embedded in the walls, and the outer ends of the embedded steel bars will be exposed. Such embedded steel bars are generally used as connectors to connect different components, such as beam-column connections, wall connections, etc., which can effectively connect walls with other structural components to form a more stable overall structure. In the actual construction process, exposed steel bars will inevitably rust, and the rusted steel bars need to be treated. The conventional treatment method is manual grinding or direct spraying of rust removers. Manual grinding is time-consuming and labor-intensive; since the embedded steel bars are not very concentrated, direct spraying of rust removers will cause most of the rust removers to be unable to contact the steel bars, resulting in waste. They are also easily inhaled by humans during spraying, which is harmful to the human body. Utility Model Content

[0003] The utility model aims to provide a rust remover for pre-buried exposed steel bars.

[0004] The utility model is realized by the following measures: a pre-buried exposed steel bar rust remover, characterized in that it comprises a V-shaped tube body with an inner diameter larger than the outer diameter of the exposed steel bar, the V-shaped tube body comprises a straight tube section and an inclined tube section, the outer end of the straight tube section is provided with a sealing ring located between the inner wall of the straight tube section and the outer wall of the exposed steel bar, and the upper end of the inclined tube section is higher than the straight tube section. The sealing ring is used to block the gap between the inner wall of the cylinder and the outer wall of the exposed steel bar.

[0005] Furthermore, the outer diameter of the V-shaped tube body is larger than the outer diameter of the exposed steel bars, and generally does not exceed 1 cm.

[0006] Furthermore, a detachable container connected to the straight pipe section is provided at the lower part of the straight pipe section, and a valve is provided between the detachable container and the straight pipe section. The valve, detachable container and straight pipe section are generally connected by threads.

[0007] Furthermore, the included angle of the V-shaped tube body is greater than 90 degrees and less than 160 degrees.

[0008] Furthermore, the outer end of the straight pipe section is provided with a circular ring plate connected with two semicircular ring plates, one semicircular ring plate is fixedly connected to the straight pipe section or made in one piece, and the two semicircular ring plates are connected in a detachable manner;

[0009] The sealing ring is formed by splicing two semicircular rubber strips, and the two semicircular rubber strips are respectively arranged in the corresponding semicircular ring plates. Since the inner diameter of the sealing ring is smaller than the outer diameter of the steel bar, it is difficult to insert the steel bar when one end of the sealing ring is inserted. Therefore, the sealing ring is set into two pieces, one of which is connected in a detachable manner, so that the insertion of the steel bar can be facilitated. The thickness of the semicircular rubber strip can be determined according to the actual situation, and the sealing ring can play a certain limiting role through the friction between the sealing ring and the steel bar.

[0010] Furthermore, the two semicircular ring plates are connected by bolts.

[0011] Furthermore, the outer end of the inclined pipe section is an outwardly expanded bell mouth, which is convenient for pouring in the rust remover.

[0012] Furthermore, a detachable filter screen is provided at the inlet of the detachable container.

[0013] Furthermore, the detachable container is made of a transparent material, which facilitates observation of the height of the rust remover inside and the degree of impurities contained therein.

[0014] Working principle:

[0015] Insert one end of the straight pipe section from the exposed section of the steel bar until the entire steel bar is covered, keep the inclined pipe section higher than the straight pipe section, pour rust remover from the bell mouth of the inclined pipe section until the straight pipe section is filled with rust remover. At this time, the sealing ring can prevent the leakage of the rust remover. The inclined pipe section is higher than the straight pipe section, and will not cause the rust remover to flow out. Maintain it for a certain period of time, and the rust remover soaks the steel bar to achieve the purpose of rust removal.

[0016] After the rust removal is completed, the valve is opened, and the rust remover flows into the detachable container, and the filter screen can filter out some large particles of impurities. The rust remover in the detachable container can be reused according to actual conditions.

[0017] The beneficial effects brought about by the technical solution provided by the embodiment of the utility model are: the V-shaped tube body is put into the outside of the steel bar, and the rust remover is poured in to remove the rust on the steel bar. The steel bar is completely immersed in the rust remover, and the rust removal effect is good; the rust remover can be recovered through a detachable container and can be reused according to actual conditions; the rust remover has a simple structure and is easy to use.
