Embodiment Construction

[0025] A construction method of prefabricated finishing (GRC) material for steel structure stair steps

[0026] 1. If figure 1 Shown:

[0027] 1.1 Cleaning of the base: remove the dirt, mortar blocks, garbage and other attachments on the base of the stair steps. If there are some prominent places, they should be chiseled. Check whether the quality of the grassroots meets the requirements;

[0028] 1.2 The horizontal line, vertical line and GRC product position line popped up on the base layer must be horizontal and vertical, and the gap between parts is uniform and consistent, and it is about ≤5mm;

[0029] 1.3 On the surface of the base layer, evenly apply a layer of 2mm thick acrylic adhesive layer;

[0030] 1.4 Cover with a 5mm thick rubber plate protective layer, and level it with a level;

[0031] 1.5 Pop up the horizontal line, vertical line and GRC product position line according to the base layer, install the GRC cover plate, and adjust the gap of the GRC cover pla...

Abstract

The invention relates to a construction method for prefabricated decorative finish of steel structure stair steps, and belongs to the technical field of steel structure stair construction. The methodincludes the steps that components are transported to a site to be checked, and construction materials and construction equipment are prepared; dirt on a basic layer is removed, and the surface of thebasic layer is evenly coated with a layer of acrylic acid type adhesive which is 1 mm-2 mm thick; a rubber plate protective layer covers the basic layer, and a horizontal line, a perpendicular line and a GRC product position line are obtained through flipping; a GRC cover plate is fixed and welded; a GRC product is hung, and a seam is filled with cement mortar and an acrylic acid type adhesive; the jointing position of the GRC product and the basic layer is padded with a layer of rubber plate which is 3 mm-6 mm thick. The construction method has the advantages that total mass is small, combination is flexible, construction is convenient and rapid, secondary decoration is not needed, and the prefabricated decorative finish keeps uniform with ambient decorative styles easily.

Description

technical field [0001] The invention belongs to the technical field of steel structure staircase construction, and in particular relates to a construction method for prefabricated decorative surfaces of steel structure staircase steps. It is suitable for installation and fixing of old steel structure stair steps covered with glass fiber reinforced concrete (GRC) material plates under various conditions and various decoration styles. Background technique [0002] At present, for building interior decoration, especially for higher-end decoration projects, GRC is an inorganic composite material made of cement mortar with GRC additive materials as the base material and glass fiber as the reinforcement material. GRC has excellent properties that concrete and cement mortar cannot have, such as tensile strength, good crack resistance, thin product, light weight, good impact resistance, etc. Odor, harmless to the human body and the environment, no pollution, etc., so it has been mo...
