Gap anti-cold-bridge structure of steel frame roof panel and construction method thereof

Abstract

The invention discloses a gap anti-cold-bridge structure of a steel frame roof panel and a construction method thereof. According to the gap anti-cold-bridge structure of the steel frame roof panel, a big-end-up cold bridge gap is formed between oppositely arranged end ribs of two steel frame roof panels, the cold bridge gap is provided with a necking part, the necking part is filled with a heat preservation rod, a main rib at the top of each steel frame roof panel is provided with a concave part, and the concave part is provided with a heat preservation plate which is used for sealing the cold bridge gap, the concave part is evenly filled with a heat preservation mortar layer covering the heat preservation plate, and the heat preservation mortar layer and the steel frame roof panel are covered with waterproof coiled materials. A prior gap welded arch against heat preservation rod structure is replaced, gap filling technological process is reduced, construction efficiency is improved. In addition, due to structural design that the cold bridge gap is large in upper part and small in lower part, the roof panel is prevented from expanding with heat and contracting with cold, and meanwhile, indoor and outdoor heat exchange can be effectively weakened. According to the gap anti-cold-bridge structure and the construction method thereof, the cold bridge phenomenon is effectively avoided, and the construction efficiency and quality are improved.

Description

technical field [0001] The invention relates to the technical field of roof panel construction, in particular to a gap cold-proof bridge structure of a steel frame roof panel and a construction method thereof. Background technique [0002] The steel frame light roof panel is a panel that can directly bear the roof load and is located on the roof of the house. It is generally composed of a steel frame, a steel skeleton, a light concrete insulation core material, and ceramsite concrete upper and lower layers. It has the characteristics of light weight, load bearing, heat preservation and heat insulation. During the construction process, refer to the "Steel Frame Lightweight Roof Panel" National Building Standard Design Reference Atlas. After the installation and welding of the steel frame light roof panel is completed, the seams between the panels need to be cleaned. Due to the steel frame in the standard design The seam height of the light roof grid slab is only 40mm, so tap...
