Abstract

The invention discloses a gym metal roof surface maintaining construction method. The method comprises the steps of (1), rusted gutter mending; (2), roof surface base layer cleaning; (3), detail nodesealing enhancing treatment; (4), mechanical liquid rubber coating spraying; (5) coated film base layer cleaning; (6), exposable acrylic acid waterproofing coating mechanical spraying for once; (7) exposable acrylic acid waterproofing coating mechanical spraying for the second time to reach the regulated thickness of 2 mm; (8), coated layer mending process, and mechanical liquid rubber coating spraying; (9), inspection and acceptance. According to the method, after an overall waterproofing layer is completely dried, a watering experiment is conducted on the inspected and accepted metal roof surface, and the construction is qualified if there exists no water seepage. By means of the method and the application of the mechanical liquid rubber coating spraying construction technique, the waterproofing processing and the maintaining engineering project of a large gym metal roof surface are efficiently completed.

Description

technical field [0001] The invention belongs to the technical field of waterproof construction, and in particular relates to a maintenance construction method for a metal roof of a gymnasium. Background technique [0002] The gymnasium is mainly used as an indoor ball game, dance and other activity venues. It generally adopts a steel structure. The roof is mostly a double-layer steel frame-type color steel structure, covered with light-weight color-coated steel plates, and supplemented by heat-insulating core materials in the middle. However, affected by external factors such as exposure, rain and snow, temperature changes, cleaning and maintenance, etc., color steel plates are prone to rust, warping, degumming, loosening and other problems, resulting in water leakage during use in the rainy season, affecting indoor The normal use of the site also poses a greater hidden danger to the safety of the steel structure. Contents of the invention [0003] For the technical probl...
