Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of fire prevention of curtain walls of high-rise buildings, and in particular relates to a fire prevention device for external thermal insulation materials of curtain walls of high-rise buildings. Background Art
[0002] The country advocates a sustainable development model that is energy-saving and environmentally friendly, and corporate production has also continuously responded to the country's call for environmental protection. In today's construction industry, due to the country's emphasis on environmental protection, environmental factors are also taken into account in the selection of building materials. Insulation materials with thermal insulation and energy-saving effects are used in the construction of a large number of high-rise buildings. However, when selecting insulation materials for building curtain walls, energy-saving factors are considered, but safety hazards are ignored, especially for high-rise building curtain walls. Since the internal structure of the curtain wall is hollow, once a fire occurs in a high-rise building, the internal connection parts of the high-rise building curtain wall will form a chimney effect, and all insulation materials will become catalysts for the outbreak of fire, further exacerbating the risk of fire.
[0003] In the process of rapid development of building curtain wall insulation engineering, the fire prevention problem of insulation materials has been plaguing the entire building-related industry. All parties have been looking for improvement plans and thorough solutions for this, but progress has been slow. At present, several new insulation materials have emerged, such as nanoporous insulation materials, composite insulation materials asbestos substitutes, etc. With the continuous development of nanotechnology, nanomaterials are becoming more and more popular. Nanoporous siliceous insulation materials are new applications of nanotechnology in the field of insulation materials. Most of the pore sizes in the constituent materials should be in the nanoscale. According to the theory of molecular motion and collision, the heat transfer of gas is mainly through the collision between the higher-speed molecules on the high-temperature side and the lower-speed molecules on the low-temperature side. Since the freedom of nitrogen and oxygen, the main components of air, is about 70 nm, when the micropore size of the silica particles in the nanoporous siliceous insulation material is smaller than this critical size, convection is eliminated inside the material, which essentially cuts off the heat conduction of the gas molecules, thereby obtaining a lower thermal conductivity than air without convection. However, due to various reasons, such as high cost, difficulty in obtaining materials, and complex construction, the above insulation materials have not been widely popularized in China, and even remain in the laboratory stage. Summary of the invention
[0004] The purpose of the present invention is to provide a fireproof device for external thermal insulation materials of high-rise building curtain walls in view of the problems that in the prior art, when a fire occurs in a high-rise building curtain wall, the internal connection parts will form a chimney effect, and all thermal insulation materials will become catalysts for the outbreak of fire. On the other hand, the fireproof materials of high-rise building curtain walls are expensive, the construction is complicated, and they are difficult to apply to actual projects.
[0005] The technical solution adopted by the present invention is as follows:

[0007] Preferably, the fireproof separation cavity includes a bottom plate and four side plates, and the two vertical side plates are provided with reserved installation grooves for the curtain wall cross purlins to pass through, and the ends of the bottom plate and the side plates are embedded and installed in the insulation layer and the wall in turn.
[0008] Preferably, the fireproof separation cavity further comprises an auxiliary isolation plate, the auxiliary isolation plate matches the reserved installation groove, and the auxiliary isolation plate is installed in the reserved installation groove after being in place.
[0009] Preferably, a gas-proof and moisture-proof film is further provided on the side of the thermal insulation layer in contact with the wall base layer.
[0010] Preferably, the air-barrier and moisture-proof film is adhered with butyl tape.
[0011] Preferably, the thermal insulation layer is made of thermal insulation rock wool.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0016] 1. When a fire occurs in a high-rise building curtain wall in the prior art, the internal connection parts will form a chimney effect, and all the insulation materials will become a catalyst for the outbreak of the fire. On the other hand, the fireproof materials for high-rise building curtain walls are expensive, the construction is complicated, and it is difficult to apply them to actual projects. In the scheme of the present invention, a fireproof partition cavity is used to divide the gap between the wall base and the decorative panel into multiple independent spaces, so that independent partitions are formed in the event of a fire, preventing the internal passage from forming a chimney effect, and effectively improving the fireproof performance of such hanging and installed curtain walls.
[0017] 2. Since the keel occupies a large space, when installing the device of this solution, it is necessary to open a reserved installation groove on the fire partition board, which to a certain extent destroys the independence of the fire partition. In response to this problem, this solution further designs an auxiliary isolation board. After the fire partition board is installed, the auxiliary isolation board is used to fill and seal the gap in the reserved installation groove, thereby ensuring the independence of the fire partition and further improving the fireproof performance of this device.
