1results about How to "Improve troweling efficiency" patented technology

This application relates to the field of concrete construction and discloses a concrete smoothing device for building construction. In this application, a sliding groove for a sliding connector is provided above the main smoothing plate. Sliding protrusions for the sliding connector are slidably connected to both sides of the sliding groove. A sliding connector is connected to each sliding protrusion. A sliding connector rotating rod is connected to the sliding connector. A fixed rotating block is connected to the sliding connecting rod. A telescopic smoothing plate is connected to the telescopic smoothing plate. A force transmission rod is rotatably connected to the inner side of the force transmission rod rotating connecting block. A rotating connector is rotatably connected above the force transmission rod. A lifting ring is rotatably connected to the rotating connector. An internal thread is fixedly connected to the inner side of the lifting ring. Through the contraction and expansion of this device, its practicality can be improved, making it widely applicable to on-site construction. This allows for its promotion, generates economic benefits, and improves the construction efficiency of concrete smoothing.
