[0030] In the prior art, fireproof curtain walls need to be sealed to reduce gaps to prevent the spread of fire; but the closed curtain wall design will hinder indoor air circulation, making the indoor air turbid. Chinese patent CN115522666A provides a high-strength fireproof curtain wall, in which a convenient ventilation mechanism is designed. The convenient ventilation mechanism includes a pre-buried ventilation pipe. By controlling the power of the electromagnet to generate magnetic force, the ferroalloy connector can be adsorbed, prompting the blocking disk to rotate on the back of the opening and closing circular plate through the rotating seat and stretching the elastic part, releasing the blocking disk from closing the vent, and the outdoor air can then pass through the vent and the inner cavity of the pre-buried ventilation pipe into the room, that is, the function of convenient ventilation is realized. It can be seen that the device has a complex structure, and the opening and closing of the vent must be controlled by an electromagnet, and the production and use costs are relatively high.

[0031] In order to solve the above technical problems and manufacture a fireproof curtain wall with ventilation function at a lower cost, the present application provides a fireproof curtain wall, including a frame 1 and a fireproof glass 2 arranged in the frame 1;

[0032] The frame 1 is provided with a longitudinal partition column 3, and the fireproof glass 2 is arranged on both sides of the partition column 3;

[0033] The partition column 3 is provided with a ventilation channel 301 along the thickness direction of the fireproof curtain wall. The ventilation channel 301 is provided with a support column 303 , and the support column 303 is coated with an intumescent fireproof coating.

[0034] The present application provides ventilation and air permeability to the curtain wall by setting a ventilation channel 301 on the partition column 3, thereby enhancing the freshness of the indoor air; since the support column 303 in the ventilation channel 301 is coated with an expandable fire-retardant coating, when encountering a fire, the expandable fire-retardant coating will expand and rapidly increase, filling and sealing the ventilation channel 301, preventing the fire from spreading into the room and isolating the high temperature.

[0035] It should be noted that the size of the ventilation duct 301, the size of the support column 303 and the thickness of the intumescent fire retardant coating are three interrelated design elements. During the design, the expansion multiple of the intumescent fire retardant coating should be considered, and a gap should be reserved between the support column 303 and the ventilation duct 301. At the same time, the coating thickness should be designed to ensure that the intumescent fire retardant coating can fully fill the gap in the ventilation duct 301 after expansion to form a barrier.

[0036] As a preferred embodiment of the present application, at least two support columns 303 are provided in the partition column 3, and the at least two support columns 303 are arranged along the thickness direction of the fireproof curtain wall. More preferably, the support columns 303 are not arranged in a straight line in the ventilation channel 301, that is, they are arranged in a staggered manner, which can effectively ensure the blocking effect on the channel after expansion. At the same time, since the two ends of the channel are open, the coating can be freely deformed toward the two ends of the channel when it expands, and will not cause compression to the frame 1 structure due to the closed or too narrow space, thereby preventing the frame 1 from deforming.

[0037] As an optional embodiment of the present application, a dustproof net 302 is provided in the ventilation channel 301. The dustproof net 302 is used to prevent outdoor dust from entering the room, and multiple layers can be provided; the distance between the dustproof net 302 and the support column 303 is preferably close, so that the intumescent fire retardant coating can be bonded to the dustproof net 302 after foaming, and together form a dense barrier.

[0038] As an optional embodiment of the present application, the dustproof net 302 is arranged on the side of the ventilation channel 301 close to the outside, and an intumescent fireproof coating is coated on the dustproof net 302. The dustproof net 302 is arranged on the outermost side. When there is a fire outdoors, the dustproof net 302 is the first structure to be burned. By arranging the intumescent fireproof coating on it, the coating can block the pores of the dustproof net 302 after expansion, thereby effectively playing a fire-blocking role.

[0039] As an example, a first support column 303, a second support column 303 and a third support column 303 are arranged in a diagonal line in which the first support column 303 is close to the indoors and the third support column 303 is close to the outdoors. A first dustproof net 302 is arranged 2.5 cm outside the wall of the first support column 303 and a second dustproof net 302 is arranged 2.5 cm inside the wall of the third support column 303. This combination forms multiple barriers, and the intumescent fireproof coating of each barrier can be connected to each other and fill the gaps after expansion to improve the sealing effect.

[0040] As an optional embodiment of the present application, the thickness of the partition column 3 is less than the thickness of the frame 1. The frame 1 can protect the partition column 3 from rain and prevent rainwater from entering the ventilation channel 301. In one embodiment, the upper edge of the frame 1 can be designed to be inclined, inclined toward the outdoor direction and extending a certain distance, which can divert rainwater and further prevent rainwater from entering the ventilation channel 301.

[0041] As an optional embodiment of the present application, the bottom surface of the ventilation channel 301 is inclined toward the outdoors, that is, the bottom surface of the ventilation channel 301 has a certain slope, so that rainwater can flow out quickly after entering the ventilation channel 301, rather than continuously accumulating in the channel or flowing into the room.

[0042] As an optional implementation of the present application, the fireproof curtain wall also includes tempered glass, which is overlapped with the fireproof glass 2, with the tempered glass close to the indoor side and the fireproof glass 2 close to the outdoor side.

[0043] As an example, the fireproof glass 2 is composed of two layers of glass (or three layers or more), and the fireproof glue is poured between the two layers of glass. After solidification, the fireproof glue becomes a transparent jelly and is bonded to the glass. The glass is sealed with a special flame retardant adhesive strip. Of course, other types of fireproof glass 2, such as non-insulating fireproof glass 2, can also be selected according to the requirements of fire resistance, heat insulation or light transmittance.

[0044] As an optional embodiment of the present application, a ventilation adjustment baffle is provided on one side of the ventilation channel 301 close to the indoor direction. The ventilation adjustment baffle is made of ablation-resistant metal material and is used to adjust the ventilation volume. When it is cold in winter, the ventilation can be reduced by adjusting the baffle, or the ventilation adjustment baffle can be completely closed to isolate outdoor noise.

[0045] As an optional embodiment of the present application, the ventilation adjustment baffle is an adjustable louver structure 6. The louver structure 6 can be adjusted to any angle, and the adjustment operation is convenient. Specifically, a sound-absorbing louver can be used. The sound-absorbing louver is also called a louver silencer or a sound-absorbing louver. The louver silencer generally has a sound absorption capacity of 5dB-15dB, and the sound absorption characteristics are medium and high frequency. The sound absorption performance of the louver silencer is mainly determined by factors such as the form of the single louver, the louver spacing, the installation angle and the effective sound absorption length. The ventilation sound-absorbing louver structure 6 is a window-type structure that can eliminate noise. It is made of high-quality materials such as stainless steel, high-quality aluminum alloy, galvanized steel plate, etc. according to the requirements of the use environment. In addition, it is made of special processing technology and can be used in any climatic conditions. It has low airflow resistance, large sound absorption capacity, and beautiful appearance.

[0046] As an optional embodiment of the present application, a splicing groove is provided at the left end of the frame 1, and a splicing block matching the splicing groove is provided at the right end of the frame 1. Each fireproof curtain wall can be spliced ​​with the fireproof curtain walls on the left and right through the splicing groove and the splicing block. Adjacent frames 1 are tightly connected without gaps, which can effectively prevent the flame from spreading inward.

[0047] As an optional embodiment of the present application, the frame 1 is provided with a mounting component 7 for assembly with a wall. The mounting component 7 can adopt a conventional component for installing a glass curtain wall, that is, it can be installed at a preset installation location on the wall (embedded parts on the wall or horizontal and longitudinal beams) by using threaded holes in combination with bolts or screws.

[0048] Those skilled in the art will appreciate that the embodiments described herein are intended to help readers understand the principles of the present invention, and should be understood that the protection scope of the present invention is not limited to such specific statements and embodiments. Those skilled in the art can make various other specific variations and combinations based on the technical inspirations disclosed in the present invention without departing from the essence of the present invention, and these variations and combinations are still within the protection scope of the present invention.
