A film covering equipment after the initial setting of concrete and before the final setting

Abstract

The invention provides a film covering equipment after the initial setting of concrete and before the final setting, which belongs to the technical field of film covering equipment structure for civil engineering, and solves the problem that cracks will still appear on the already dry road surface, and the humidity coverage cannot be achieved, and the road surface cannot be guaranteed. There is a problem of cracking due to rapid drying. A coating equipment for concrete after initial setting and before final setting, including a high-frequency vibrating seat; the high-frequency vibrating seat is composed of a top power supply and a high-frequency vibrator at the bottom, and a thin plate-shaped The film-pressing plate, and the middle position of the film-pressing plate is bolted to the bottom mounting plate of the high-frequency vibrating seat; a set of water supply mechanism is installed on the front side of the device, and this mechanism is set by using the bottom side of the front bucket cavity to tilt forward and downward. The foam seat can reapply the injected clean water to the film conveyed backwards synchronously, and the film on the film roller moves backwards layer by layer.

Description

technical field [0001] The invention belongs to the technical field of film-covering equipment structure for civil engineering, and more specifically relates to a film-covering equipment after concrete initial setting and before final setting. Background technique [0002] In the concrete pouring project, after the concrete vibration is completed, the surface should be treated according to the project requirements. The method is to repeatedly press and wipe the concrete surface with an iron trowel or wooden trowel until the surface finish required by the project is achieved. This process is called concrete collection. The surface is mainly closely related to the initial setting time of the concrete. The key to the quality of the surface is the grasp of the time; after the concrete surface is usually covered, the so-called concrete coating refers to the surface after the concrete is poured. Its surface is covered with a plastic film to prevent the rapid evaporation of water a...

Problems solved by technology

[0004] The existing technical problems to be raised by this design are not limited to the similar structures provided by the above-mentioned patents. The designer found that the market is similar to the above-mentioned structures, and the push-type concrete coating device after the initial setting and before the final setting, although it can be used manually The push or drive method makes the film roller slowly cover the maintenance film on the concrete pavement that has just been constructed. When the film is covered on the concrete pavement by this kind of device, its original moisture protection effect will be lost. Even if the film is covered on the concrete pavement again, cracks will still appear on the already dry pavement, and the humidity coverage will not be achieved. And there is no guarantee that the pavement will not crack due to rapid drying
