Description

Non-adhesive drainage structural member for light steel building roof Technical Field The utility model belongs to the technical field of light steel sloping roof water prevention, and particularly relates to a non-adhesive drainage structural member of a light steel building roof. Background Along with the increase of the pace of industrial structure adjustment of the country, the development direction of the building industry is changed, the economy of the plain entity is improved, the pursuit of sustainability is developed into a main melody, a large number of light steel building projects such as industrial workshops, gymnasiums and the like are developed in each place, the trend of the times is complied with, the response to the call of the national administration guidelines is the correct way for the survival and development of enterprises, and the improvement of the light steel building quality safety control construction technology innovation has very strong practical significance under new situation. The drainage structure of the existing light steel building roof is generally a single-layer drainage structure, the drainage structure is sealed by traditional processes such as cement and silica gel, and the sealing connection mode is easy to be influenced by ambient temperature, deforms and even cracks of joints due to expansion with heat and contraction with cold, so that the problems of water leakage and unsmooth drainage are caused. In order to solve the problems, the utility model provides a non-adhesive drainage structural member for a light steel building roof, which solves the leakage problem through structural optimization, mechanical fixation and drainage path design. Disclosure of utility model In order to solve the problems in the prior art, the utility model provides a non-adhesive drainage structural member for a light steel building roof, which has the characteristics of convenient construction and good waterproof effect. In order to achieve the purpose, the technical scheme is that the non-adhesive drainage structural member of the light steel building roof comprises a top drainage mechanism arranged at the top of the roof and a U-shaped diversion trench arranged at the junction of a high-low span and a gable flashing, wherein the top drainage mechanism comprises: An upper ridge cover plate which is an inverse V-shaped member; The lower ridge cover plate is an inverse V-shaped member, and is positioned at the bottom side of the upper ridge cover plate, and the upper ridge cover plate and the lower ridge cover plate are staggered and stacked to form a top drainage mechanism with a double-layer structure; The rubber plug is fixed between the upper ridge cover plate and the lower ridge cover plate and is positioned at the connecting node of the upper ridge cover plate and the lower ridge cover plate. As a preferable technical scheme of the utility model, both ends of the lower ridge cover plate are provided with bending edges which are bent upwards.
