High-impermeability continuous roof system

Abstract

The invention discloses a high-impermeability continuous roof system, and belongs to the technical field of buildings. A flush side-attaching water guide column is arranged at the joint of a roof panel body, hydrophobic sealing strips are conventionally arranged on the inner side of the side-attaching water guide column for seepage prevention, and rain blocking steel wires are arranged in advanceto intercept and guide rainwater, so that gathering of the rainwater at the hydrophobic sealing strips is reduced; meanwhile, seepage-sensing expansion rods are introduced into the hydrophobic sealingstrips, magnetic drive variable anti-seepage balls and water absorption balls are arranged at the corresponding ends, the arc-shaped characteristic and the water swelling characteristic of the seepage-sensing expansion rods are utilized, and once water seeps into a joint, the anti-seepage action of the seepage-sensing expansion rods is triggered immediately, the seepage-sensing expansion rods areexpanded and force the magnetic drive variable anti-seepage balls to move in the preset extending direction, so that the magnetic drive variable anti-seepage balls on the adjacent hydrophobic sealingstrips are connected under the magnetic action; and meanwhile, the hydrophobic sealing strips are driven to deform in a flat s mode, a natural anti-seepage belt is formed, and the anti-seepage performance of the continuous roof system is greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction, and more specifically relates to a continuous roof system with high impermeability. Background technique [0002] The metal profiled sheet is a corrugated sheet with cold-rolled thin steel plate as the substrate, galvanized or galvanized, coated with a color coating, and then rolled and formed. . It has the characteristics of flexible molding, fast construction speed, beautiful appearance, light weight, easy industrialization and commercial reproduction, and is widely used as building roof and wall maintenance materials. [0003] At present, metal profiled plates are widely used in continuous roofing systems. The base material of stainless steel continuous welding roofing systems is made of stainless steel. Taking advantage of the unique material advantages of stainless steel, such as small thermal expansion coefficient, high strength, high melting point, and good weldability, the system d...

Problems solved by technology

[0004] However, the impermeability of the continuous roof system often depends on the welding quality. Once there is a problem in the welding process, the impermeability will be greatly disturbed. At the same time, with the popularity and development of prefabricated buildings, welding is gradually replaced by prefabricated connections. Instead, its convenient disassembly and installation features are incomparable to welding, but at the joints of roof panels, new requirements for impermeability are put forward. At present, a new high impermeability continuous roof system is urgently needed to meet the traditional requirements. Welding process, while incorporating a new fabricated connection
