Constructing method of super-thick large-size GRC decoration column

Abstract

The invention discloses a constructing method of a super-thick large-size GRC decoration column. The method includes the following steps of thoroughly concrete slabs and a concrete wall, cutting the GRC decoration column in the length direction into a GRC column bottom decoration part, a GRC column top decoration part and a plurality of GRC column body decoration parts. The GRC column bottom decoration part, the GRC column body decoration parts and the GRC column top decoration part are spliced and fixed between the upper concrete slab and the lower concrete slab along the concrete wall. The space among the edge of the GRC decoration column, the upper concrete slab, the lower concrete slab and the concrete wall is filled with sealant. Alkali-resisting mesh cloth, an anti-crack mortar plastering layer and a stone-like paint spray-coating layer are sequentially laid on the outer surface of the GRC decoration column from inside to outside. Operation is easy, construction is easy, construction efficiency is improved, the waterproof performance and anti-crack performance of the GRC decoration column are increased, the service life of GRC decorations is prolonged, product stability is improved, and the later-period appearance quality is ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of an ultra-thick and large-volume GRC decorative column. Background technique [0002] With the continuous development and progress of the construction industry, most of the current engineering construction uses green and environmentally friendly materials. In super high-rise buildings, GRC decorations with low density and good flame retardancy have been affirmed by the construction industry. And widely used in various projects. At present, small-scale products are routinely used on construction sites, which can be fixed by screw rods, but large-volume and ultra-thick GRC decorative columns are used in super high-rise buildings as the building appearance. If the conventional method is adopted, the installation of GRC products will first be affected to a certain extent, and the materials will need to be purchased separately. Then, due to the h...

Problems solved by technology

However, this method has certain limitations. Firstly, the material is not conducive to the site, and then it is not suitable for the use of large-volume GRC products on super high-rise buildings. It cannot guarantee the later construction quality and service life, and it is easy to cause cracking on the surface of GRC products.
