Embodiment Construction

[0033] Below in conjunction with specific embodiment, the present invention is further described as follows:

[0034] The present invention comprises the following steps:

[0035] 1) Basic wall treatment: clean the wall, make it flat and dry, repair the wall plug seams and wire grooves, smooth and firm the convex and concave parts and non-reserved holes on the basic wall, and install the inner wall concrete wall construction bolts The hole is blocked;

[0036] 2) According to the flat and vertical condition of the surface of the base wall, use one wall as a reference to hang vertical, square, and play control lines;

[0037] 3) Make corner protection with gypsum-based plaster mortar;

[0038] 4) Use gypsum-based plastering mortar to make ash cakes and punch bars: take the control line 200mm away from the base wall as the reference control line, and set it up at the intersection point of the reference control line through two laser line projection instruments, and place it di...

Abstract

The invention relates to a gypsum heat preservation painting mortar construction process which comprises the steps that firstly, a base-layer wall is processed; secondly, according to the smoothness and perpendicularity of the surface of the base-layer wall, one wall is used as the datum, and a perpendicular square-setting elastic control line is hoisted; thirdly, gypsum bases are painted with mortar and used as angle beads; fourthly, the gypsum bases are painted with mortar and used as ash cakes and punching ribs; fifthly, gypsum heat preservation painting mortar is sprayed; sixthly, the gypsum heat preservation painting mortar is flattened and compacted, wherein the step of hanging nets on the junctions of different materials is further included between the second step and the third step; in the fourth step, after the ash cakes are manufactured and hardened, distribution cakes are manufactured and arranged through flax threads by controlling the ash cakes, so that the horizontal spacing between all the distribution cakes is not larger than 1500 mm; the steps of rib grinding and rib alignment are further included between the fourth step and the fifth step. Compared with the prior art, the gypsum heat preservation painting mortar construction process has the advantages that construction is convenient, plastering, scraping and repair are easy, the labor intensity is low, material consumption is lowered, the construction period is shortened, and construction cost is saved.

Description

[technical field] [0001] The invention relates to the technical field of gypsum thermal insulation plastering mortar, in particular to a construction process of gypsum thermal insulation plastering mortar. [Background technique] [0002] Gypsum thermal insulation plastering mortar is a high-efficiency and energy-saving building interior wall and roof plastering material made of gypsum as the main cementitious material, adding sand, certain admixtures, special compound additives and thermal insulation particles. It mainly replaces cement , Lime mortar and other plastering materials not only have the effect of ordinary plastering but also meet the requirements of heat preservation and energy saving, and are suitable for various walls. [0003] Gypsum thermal insulation plastering mortar is a new type of building material that meets the national building material standards, has excellent performance, and is environmentally friendly and energy-saving. Traditional cement and lim...
