Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of energy-saving building curtain wall engineering, and particularly relates to an energy-saving daylighting roof system with a fireproof function and an installation process thereof. BACKGROUND

[0002] The glass daylighting roof has the functions of permeability and daylighting, is generally applied to the atrium or top roof of a building, and plays a good decoration role for the building. According to relevant specification requirements, in view of the safety and energy-saving requirements of daylighting, the glass daylighting roof in the design adopts homogeneous tempered glass or laminated hollow glass to reduce the self-explosion rate of the glass, improve the safety of the glass daylighting roof, and adopt laminated hollow glass or increase a sunshade system to meet the energy-saving requirements.

[0003] The glass daylighting roof can be divided into frame-type glass daylighting roof, point-type glass daylighting roof and full-glass-type glass daylighting roof according to the support structure form of the panel. Among them, the frame-type glass daylighting roof refers to the form that the glass panel is connected and fixed with the support structure through a frame. The main structure levels of the frame-type glass daylighting roof are: glass panel-aluminum alloy sub-frame-aluminum alloy pressing seat-steel structure or aluminum structure support structure system.

[0004] Since the glass daylighting roof is mostly located in the atrium or top roof of a building, once a fire occurs, the glass daylighting roof will instantaneously fall off when the fire burns to the glass daylighting roof, and then a "smoke stack effect" is formed to increase the fire. The structure of the conventional glass curtain wall cannot be applied to the glass daylighting roof system. For example, a new energy-saving exposed frame glass curtain wall system disclosed in a Chinese utility model patent with the authorization announcement number CN205677124U and the authorization announcement date of 2016.11.09, which comprises aluminum alloy frames, inter-panel multi-cavity structures and aluminum alloy cover plates connected in sequence. The inter-panel multi-cavity structure comprises three ethylene-propylene-diene rubber strips, hollow glass panels, sealing rubber strips, hollow glass panels, three ethylene-propylene-diene rubber strips and aluminum alloy pressing plates connected in sequence. The hollow glass panel comprises a plurality of glass panel blocks uniformly distributed, and a foam rod and a silicone sealant are arranged at the gap between the adjacent two glass panel blocks. The three seals and air double cavities used in the new energy-saving exposed frame glass curtain wall system improve the energy-saving effect, but the structure form is limited to application in the exposed frame glass wall. According to the process of the hidden frame glass curtain wall, the three ethylene-propylene-diene rubber strips and the aluminum alloy pressing plate do not exist, and the third seal and the air double cavity are naturally not formed, so the application range is fixed. Secondly, the profile material of the new energy-saving exposed frame glass curtain wall system is aluminum alloy material, and the high-temperature resistance performance is not ideal, which cannot meet the fireproof requirements.

[0005] In summary, how to avoid or slow down the falling off of the glass daylighting roof when it meets fire, win the escape and fire extinguishing time, and innovate an energy-saving daylighting roof system with a fireproof function become necessary for safe use. SUMMARY
