Film covering equipment before final coagulation after primary coagulation

Abstract

The invention provides film covering equipment before final coagulation after primary coagulation, and belongs to the technical field of the structure of the film covering equipment for civil engineering. The film covering equipment solves the problems that cracks are generated on the road surface which is dried for a long time, wetting covering can not be met, and the phenomenon that the road surface does not crack due to rapid drying can not be ensured. The film covering equipment before final coagulation after primary coagulation comprises a high-frequency vibration base, wherein the high-frequency vibration base is composed of a top power supply and a bottom high-frequency vibrator, a thin plate-shaped film pressing plate is mounted on the bottom surface of the high-frequency vibrator,the middle position of the film pressing plate is fixedly connected with a bottom mounting plate of the high-frequency vibration base through bolts, the front side of the equipment is provided with aset of water supply mechanism, the water supply mechanism utilizes foam seats obliquely arranged at the front lower portion of the bottom side of a front side barrel cavity so that the injected clearwater can be synchronously coated to the backward conveyed film in an infiltration mode, and backward action is performed following the film on the film roller one by one.

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
