DETAILED DESCRIPTION
[0015] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0017] like Figure 1 As shown, an interlayer fire protection structure of an inner inclined curved glass curtain wall comprises a steel beam 1, a floor slab 2, and an inner inclined curved glass curtain wall 3. The steel beam 1 is an inclined structure, and its inclination direction is the same as that of the inner inclined curved glass curtain wall 3. The steel beam is arranged on the lower side of the floor slab 2, and a plurality of fire protection structures are arranged between the inner inclined curved glass curtain wall 3, the steel beam 1 and the floor slab 2.
[0018] The fireproof structure mainly includes rock wool and a stainless steel plate for fixing the rock wool, wherein a top rock wool 4 is arranged between the floor 2 and the inner inclined curved glass curtain wall 3, and the top rock wool 4 is fixed to the lower side of the top stainless steel plate 5 by a plurality of angle steels 12, one end of the top stainless steel plate 5 is connected to the floor 2 and the other end is connected to the top rectangular tube 6, wherein the angle steel 12 and the top rectangular tube 6 are both connected to the vertical keels of the curtain wall on the left and right sides to provide an installation and fixing foundation for the top stainless steel plate 5, thereby fixing the top rock wool 4.
[0019] A bottom rock wool 7 is arranged between the bottom of the steel beam 1 and the inner inclined curved glass curtain wall 3. The bottom rock wool 7 is fixed to the upper side of the bottom stainless steel plate 8 through an angle steel 12. One end of the bottom stainless steel plate 8 is connected to the steel beam 1 and the other end is connected to the bottom rectangular tube 9. The bottom rectangular tube 9 is connected to the vertical keels of the curtain wall on the left and right sides to provide an installation and fixing foundation for the bottom stainless steel plate 8, thereby fixing the bottom rock wool 7.
[0020] An inclined rock wool 10 is arranged between the top rock wool 4 and the bottom rock wool 7. The inclined rock wool 10 is fixed to the side stainless steel plate 11 by rock wool fixing nails. The side stainless steel plate 11 is abutted against the inner inclined curved glass curtain wall 3. Its upper end is connected to the top rectangular tube 6, and its lower end is connected to the bottom rectangular tube 9.
[0021] Among them, the top rectangular tube 6 and the bottom rectangular tube 9 are bent into a curved surface structure in the same manner as the architectural design to ensure the consistency of the curvature change. The angle steel 12 is bent into a curved surface structure in the same manner as the rectangular tube to ensure the consistency of the curvature change. It also prevents the fixed stainless steel plate from being deformed due to the large span and heavy rock wool, which affects the fire resistance. At the same time, in order to ensure the sealing and fire resistance, the top stainless steel plate 5 and the bottom stainless steel plate 8 need to be designed into a curved surface shape, and the curvature is consistent with the changing curvature of the curtain wall. The width of the top stainless steel plate 5 should be wider than that of the bottom stainless steel plate 8, and its width should be guaranteed to cover the position from the floor 2 to the top rectangular tube 6 and the position from the steel beam 1 to the bottom rectangular tube 9. The ends and joints of the top stainless steel plate 5 and the bottom stainless steel plate 8 need to be sealed with fireproof sealant. The surface of the steel beam 1 needs to be sprayed with fireproof paint.
[0022] The top rock wool 4, the bottom rock wool 7, the inclined rock wool 10 and the steel beam 1 together form a closed fireproof space to prevent flames and smoke from penetrating into the upper space from the gaps when a fire occurs. The bottom rock wool 7 intersects with the steel beam 1 and the inclined rock wool 10 to form a bottom fireproof zone, ensuring that when a fire occurs, the fire can be prevented from extending upwards in the first place. The inclined rock wool 10 is located between the top rock wool 4 and the bottom rock wool 7, forming a side fireproof zone. The inclined rock wool 10 realizes fire prevention at the inclined position, which strengthens the fire prevention of the curtain wall. The top rock wool 4 is located between the inclined rock wool 10 and the floor 2, forming a top fireproof zone. When the flame burns through the bottom rock wool 7 and the inclined rock wool 10, it plays a further fireproof role, delays the spread of the fire area, and buys more fire-fighting time for the fire-fighting.
[0023] The above embodiments describe the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the changes and modifications made by the technicians in this field shall be within the scope of protection of the claims attached to the utility model.
