Embodiment Construction

[0027] exist figure 1 Among them, one end of the fastening connector 1 vertically penetrates the surface of the upper panel 2 , and the other end is flush with the upper surface of the upper panel 2 . In order to fully exert the connection effect of the fastening connectors 1 , the fastening connectors 1 need to be evenly distributed on the surface of the upper panel 2 .

[0028] exist figure 2 In the middle, the fastening connector 1 connects the upper panel 2 and the closed thin-walled steel 3 together; on the other side, the fastening connector 1 connects the closed thin-walled steel 3 and the lower panel 5 together. The thermal insulation core material 4 is filled in the closed space formed by the ribs of the closed thin-walled section steel 3 and the upper panel 2 and the lower panel 5, without occupying additional building space. The sub button 6 and the female button 7 form a female button. During construction and installation, a single roof panel and another roof pa...

Abstract

The invention discloses a closed thin-wall steel-heat insulation core material-thin-panel compound energy-saving roof plate comprising a roof plate load-carrying member and a packing layer. The closed thin-wall steel-heat insulation core material-thin panel compound energy-saving roof plate is characterized in that the roof plate load-carrying member is formed by connecting a closed thin-wall steel plate and two side panels through fastening connecting pieces; the thickness of the open thin-wall steel plate is 0.4 mm-2.0 mm; the thickness of the two side panels is 6 mm-12 mm; the packing layer is a heat insulation core material; and the heat insulation core material is packed in a closed space enclosed by the closed thin-wall steel plate and the two side panels. Compared with the prior art, the closed thin-wall steel-heat insulation core material-thin-panel compound energy-saving roof plate has load-carrying capability much higher than that of a sandwich plate with the span of 1.5 meters under the condition that the span is 3 meters, prevents the closed thin-wall steel plate and the heat insulation core material from being subject to mechanical damage because the closed thin-wall steel plate and the heat insulation core material are effectively protected under the protection of the two side thin panels, prevents the heat insulation core material from being weathered and from water and steam and has fire prevention and corrosion resistance.

Description

technical field [0001] The invention relates to a building enclosure roof panel capable of bearing loads used in building construction and civil engineering. The roof panel integrates load bearing, enclosure and energy saving, and is especially light in weight, high in strength, good in earthquake resistance, and energy saving. Environmental protection and fast construction speed are the main features of the closed thin-walled steel-insulation core material-thin panel composite energy-saving roof panel. Background technique [0002] At present, the roof panels in the housing construction in our country mainly use cast-in-place reinforced concrete roofs as building roof panels. Since the construction process of reinforced concrete floor slab requires a lot of manpower, the construction is mostly wet work, which is easy to cause pollution to the environment, and does not conform to the development trend of building construction with factory production and on-site construction ...
