Description

Technical Field

[0001] This utility model relates to the field of anti-rust coating construction technology, specifically to a steel bar anti-rust coating device. Background Technology

[0002] In building construction, when the reinforced concrete structure is large, it needs to be poured in layers. When the lower layer is poured, exposed steel bars are reserved to connect with the upper layer. After the lower layer of concrete is poured, it needs to be cured for a long time before the upper layer of concrete can be poured. Therefore, the exposed steel bars need to be exposed to the air for a long time. In order to prevent the exposed steel bars from rusting, rust prevention treatment is required.

[0003] Currently, existing rust prevention methods mostly involve brushing rust inhibitor onto the rebar ends or spraying it onto the rebar ends with a spray gun or spray bottle. Brushing is inefficient and prone to missed areas. Moreover, in areas with dense rebar ends, it is inconvenient to reach in with your arm to apply the rust inhibitor, which can easily scratch the worker's arm. On the other hand, the rust inhibitor sprayed from a spray gun or spray bottle is in a mist form, and most of it disperses into the air, resulting in uneven application, reduced rust prevention effect, and a great deal of waste.

[0004] Based on this, the present invention designs a steel bar anti-rust coating device to solve the above problems. Utility Model Content

[0007] As a preferred embodiment of the present invention, the connector includes a first connecting seat, a second connecting seat, and a connecting pin. The second connecting seat is disposed within the first connecting seat, and the first connecting seat and the second connecting seat are movably connected by the connecting pin.

[0008] In a preferred embodiment of this utility model, the first connecting seat is fixedly connected to the upper clamping rod, and the second connecting seat is fixedly connected to the lower clamping rod.

[0009] As a preferred embodiment of this utility model, the clamping rod includes a main rod body, an arc-shaped connecting rod, and a handle. The arc-shaped connecting rod is located at the left end of the main rod body, and the handle is located at the right end of the main rod body.

[0010] As a preferred technical solution of this utility model, the arc-shaped connecting rod has a slot inside, and a protrusion is provided in the slot.

[0011] As a preferred embodiment of the present invention, the brush includes an elastic brush body, bristles, a retaining strip, and a groove. The elastic brush body has bristles on one side and a retaining strip on the other side, and the retaining strip has a groove.

[0012] As a preferred embodiment of this utility model, the snap-fit ​​strip is inserted into the snap-fit ​​groove, and the groove is snapped into the snap-fit ​​strip.
