Background
The cross-section of the post is generally square in order to facilitate structural reinforcement and already save material. And because the flow of people is big in the hospital, when people or article hit the surface of stand, the edges and corners of the stand of square cross section easily cause the damage to human body or article, so circular cross section stand is in large numbers in the hospital. The construction steps of the circular upright post are generally binding a reinforcement cage, pouring concrete, plastering mortar and installing a veneer.
The existing mortar plastering construction method comprises the following steps: s1, coating mortar on the surface of the upright post by using a scraper knife; s2, trowelling the mortar to form a first troweling surface layer; and S3, before the first plastering layer is solidified, quickly scraping and coating the mortar on the surface of the first plastering layer by using a scraper knife, and forming a second plastering layer after trowelling. When the requirement on the uniformity of mortar on the surface of the upright post is higher, the construction of a third or even a fourth plastering layer is needed.
The above prior art solutions have the following drawbacks: because the mortar plastering thickness of the column with the circular section is difficult to measure, at least two mortar plastering steps are usually required to be carried out in order to improve the uniformity of mortar on the surface of the column. After at least two mortar plastering processes, the thickness of the column mortar is only nearly uniform. And when the section of the upright column is large, a plurality of constructors are needed to cooperate to finish mortar plastering, and the plastering of all the channels can be finished before mortar is solidified. The method needs old constructors with a lot of experience to carry out, and the construction quality cannot be guaranteed.
It is desirable to provide a mortar plastering construction method of a column, which can improve the uniformity of mortar plastering.
