Problems solved by technology

Plastering the narrow spaces such as the flue or air shaft manually is low in construction efficiency, difficult to control the quality, and there are many cases of missing plastering. Very difficult
Therefore, plastering the inner walls of flues, air shafts, etc. is often regarded as a common engineering quality problem that cannot be eradicated

Abstract

The invention discloses a bilateral plastering device for a flue or an air shaft and a plastering method. The plastering device comprises a supporting frame; the two opposite sides of the supporting frame are each fixedly provided with a hopper with the lower end inclining outwards, and each hopper is a box-shaped body with the lower end being provided with a discharging outlet; the upper end of each hopper is provided with a flexible concrete conveying pipe, wherein the upper ends of the flexible concrete conveying pipes communicate with a discharging outlet of a matched stirring machine, andthe lower ends of the flexible concrete conveying pipes stretch into the hoppers; the lower end of each hopper is provided with a plaster shovel with the lower end inclining outwards, and each plaster shovel is constituted by a shovel plate and baffles arranged on the two sides of the shovel plate; and concrete enters the two flexible concrete conveying pipes, flows into the corresponding hoppersunder the self-weight effect, and then evenly flows to the plaster shovels through the discharging outlets of the hoppers, and plastering is conducted on the inner wall of the flue or the air shaft through the plaster shovels. The bilateral plastering device for the flue or the air shaft and the plastering method have the advantages of being rapid and convenient to use, good in plastering qualityand high in plastering rate.

Description

technical field [0001] The invention relates to a plastering device, in particular to a double-sided plastering device for a flue or an air shaft and a plastering method thereof. Background technique [0002] In the process of house construction, it is necessary to plaster the flue, air shaft, wall and other places to effectively protect the surface of the wall, flue, air shaft, etc., and prevent the surface of each position from sagging, The phenomenon of falling off and cracking. At present, plastering is mainly done by manual plastering or automatic plastering device to plaster the wall. Among them, manual plastering has the defects of low construction efficiency and uncontrollable plastering quality, while automatic plastering device has the disadvantages of plastering efficiency. High, and the plastering quality is good, but due to its large size, it can only be applied to large-area wall plastering. However, in specific housing construction, it is usually necessary t...
