Problems solved by technology

[0003] However, due to the vast territory of our country and the great differences in various climatic conditions, the single-layer profiled steel plate roof structure or the ordinary "sandwich panel" structure often cannot meet the requirements of cold protection, heat insulation and sound insulation (anti-roof rain, hail impact sound) ) requirements

Embodiment Construction

[0020] Embodiments of the present invention: as figure 1 As shown, the steel wire mesh 3 is hung on the top surface of the steel purlin 6, and the glass wool felt 2 is laid on the steel mesh 3 to keep the gap between the steel mesh 3 and the top layer of profiled steel plate 1 and the thickness of the glass wool felt 2 is basically equal, Make the laid glass wool felt 2 neither compressed, but also close to the bottom surface of the top laminated steel plate 1, to ensure the best effect of thermal insulation; paste rigid extruded foam on the top surface of the steel purlin 6 as heat insulation plate 4, and fix the top profiled steel plate 1 on the top of the steel purlin 6; nail the bottom profiled steel plate 5 to the bottom surface of the steel purlin 6.

Abstract

The present invention discloses a multifunctional double-layer pressed steel plate roof and its laying method. Its structure is characterized by that its top layer is pressed steel plate, between steel purlin and pressed steel plate a steel wire-mesh is set, between the pressed steel plate and steel wire-mesh a glass-fiber felt is set, between the steel wire-mesh on the steel purlin and pressed steel plate also is set a heat-insulating plate, and under the steel purlin a pressed steel plate is connected. Besides, said invention also provides the concrete steps of its laying method.

Description

Technical field: [0001] The invention relates to a building structure, in particular to a structure of a profiled steel plate roof and a laying method thereof. Background technique: [0002] With the development of economic construction, the building structure gradually replaced the traditional reinforced concrete structure by light steel structure. Because this structure has the advantages of reasonable structure, beautiful appearance, low overall cost, and short construction period, it has been widely used in new industrial plants, especially large industrial plants, in recent years. [0003] However, due to the vast territory of our country and the great differences in various climatic conditions, the single-layer profiled steel plate roof structure or the ordinary "sandwich panel" structure often cannot meet the requirements of cold protection, heat insulation and sound insulation (anti-roof rain, hail impact sound) ) requirements. Invention content: [0004] The obj...
