TECHNICAL FIELD

[0001] The present application relates to the field of building construction, in particular to a concrete spreading device. BACKGROUND

[0002] After the concrete is laid, the concrete in the construction area needs to be spread before the concrete hardens, so that the hardened concrete surface is flat. After the concrete spreading operation is completed, the concrete in the construction area needs to be maintained, that is, a maintenance film is laid on the surface of the concrete, so that the concrete surface is closely attached to the maintenance film, thereby promoting the hydration effect of the concrete and playing a role in preventing cracks and moisturizing the concrete.

[0003] In actual construction operation, the spreading and film coating of the concrete are carried out separately. The operator needs to first use a scraper with a flat surface to slide on the surface of the concrete to spread the concrete surface. After the spreading operation is completed, the maintenance film is covered to the end of the concrete by a film coating machine, and the operator then pulls the film coating machine to achieve full coverage of the maintenance film.
