Abstract

The invention relates to a roof slab joint anti-condensation structure and a construction method thereof. The construction method includes the following steps that according to the indoor temperature,the outdoor temperature and the indoor relative humidity parameter in winter in a location where a practical project is performed, and the thickness of a thermal insulation material adopted at a joint between one roof slab steel edge rib and the other roof slab steel edge rib and the thickness of a roof slab are determined; according to the roof slab construction and installation sequence, and the two roof slab steel edge ribs are in butt joint to form the slab joint; a joint material is folded into a U-shaped sheet and fills a U-shaped vertical joint at the position of the joint between theroof slab steel edge ribs so as to make the U-shaped sheet tightly press against the two sides of the vertical joint; then the joint between the roof slab steel edge ribs is filled with the thermal insulation material; the surface of the roof slab is leveled, a waterproof layer is then laid, and finally an anti-condensation roof slab building maintenance structure is formed. The structure and themethod can effectively prevent condensation phenomena of panels, the cost is low and construction is convenient to achieve.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to an anti-condensation structure for roof panel joints and a construction method thereof. Background technique [0002] Due to the difference in thermal conductivity of building materials, thermal bridges will appear where there is a good conductor of heat (such as a steel frame). The precipitation of water droplets is called condensation. Condensation usually occurs at the thermal bridge of the building, which will erode the building structure, pollute the decorative layer, and mold will appear when the condensation is severe. [0003] In the construction of a large number of industrial and public buildings, lightweight composite roof panels are often used. This kind of roof panel has significant advantages such as light weight, high strength, and fast construction speed. It is usually provided with steel edge ribs on four sides. Since steel is a good conductor of heat, ...
