Flue plastering device and method

Abstract

The invention discloses a flue plastering device and method. The flue plastering device comprises a supporting frame; the supporting frame comprises a vertical rod, and a hopper fixedly sleeves the middle of the vertical rod; the hopper is formed by four oblique plates in an enclosing mode, wherein the lower ends of the four oblique plates incline outwards correspondingly; a plastering plate is fixedly arranged below each oblique plate, wherein the lower end of the plastering plate is arranged in an outward-inclining mode; the side ends of every two adjacent plastering plates are fixedly connected, and a plastering frame in a hopper shape is formed; a flexible concrete conveying pipe is arranged at the upper end of the hopper, the upper end of the flexible concrete conveying pipe is fixedto a flue opening, and the lower end of the flexible concrete conveying pipe is adjacent to the top of the hopper; and concrete flows outside the four oblique plates of the hopper under the self-weight effect and is guided to all the plastering plates through the oblique plates, then the plastering frame is driven to ascend along with the vertical rod in the mode of lifting the vertical rod upwards, and the inner wall of a flue is subjected to multi-face plastering. According to the flue plastering device and method, the plastering efficiency and the plastering quality are high, and the four faces of the flue can be plastered synchronously at a time.

Description

technical field [0001] The invention relates to a plastering tool, in particular to a flue plastering device and a flue plastering method. Background technique [0002] During the house construction process, it is necessary to plaster the flue to effectively protect the inner surface of the flue and prevent the surface from hanging, falling off and cracking at various positions. At present, the flue is plastered manually. When plastering, it is necessary to build the flue while plastering. This construction method has low construction efficiency and is difficult to control the quality. It is often difficult to supplement the plastering of the inner wall after the masonry has reached a certain height. Therefore plastering the inner wall of the flue often cannot be eradicated as a common engineering quality problem. [0003] Based on the above reasons, the applicant intends to design a device that can plaster all the inner walls of the flue at one time, so as to improve the ...

Problems solved by technology

However, there is still no plastering device for such a small space as the flue. There is only an automatic plastering device for the wall. However, the wall plastering device is large in size and high in production cost, so it is not suitable for flue plastering.
