New fire-proof sealing technology for interlayer joints in curtain wall of high-rise building Globally, the research on the spread of fire in high-rise buildings has a long history. In the past few decades, there have been good engineering practices on how to control the spread of fire. Many countries and regions have adopted standardized tests for the fire-proof sealing method of the interlayer joints of curtain walls. Relevant building and safety regulations began to make provisions for high-rise buildings with curtain walls to ensure the safety of life and property. In order to better understand how the fire spreads in high-rise buildings with glass curtain walls, we need to imagine a scene like this: if a fire occurs on a certain floor, as the fire spreads, the indoor pressure on that floor will slowly increase, and the curtain wall The glass in the middle ruptures under the engulfing of the flame, so that more oxygen is added to the room, which encourages the fire to increase further and spread to the bottom of the board on the upper floor and the inner side of the curtain wall structure. Moreover, a certain flame may burst out of the broken window and begin to attack the outer side of the upper curtain wall structure. If there is a gap between the floor and the curtain wall structure, the flame will quickly rush from this interlayer seam to the upper floor. For this challenge, it is necessary to design and install an interlayer seam fire protection system reasonably, which can maintain stability throughout the fire It can also meet the requirements of receiving fire on both sides and avoiding the vertical spread of fire. Because many building materials of curtain wall structure are not refractory materials, it further aggravated the spread of fire in high-rise buildings. Profiles such as glass or aluminum are usually integrated into modern curtain wall structures. Under normal circumstances, these materials are deliberately made lighter and thinner, thereby weakening their fire resistance. -Under normal circumstances, the glass will shatter in 5-15 minutes after exposure to fire, and the aluminum profile will melt when it reaches 660°C. Although materials that are considered to have better fire resistance are sometimes used, these materials often fail in actual fires, for example, stone partitions such as granite, marble, travertine, or gray sandstone or the filled partition itself It is a good refractory material and will not burn. However, in a fire, these panels will rupture after being heated, and even due to different degrees of extension in all directions, or the stone contains a certain amount of moisture, it will explode after heating. Does this mean that these materials cannot be used? This is definitely not the case. The most feasible way is to improve the fire resistance of these components by adopting a simple system with high-temperature insulating materials, and at the same time, correctly install a fire-proof

sealing system. This article discusses related issues and shares related engineering application experience. (2) Introduction of fire-proof sealing system for interlayer seams Fire-proof sealing system for interlayer seams, the term quickly became synonymous with preventing the spread of fire in high-rise buildings. The fire-proof sealing system of the interlayer seam includes fire-resistant floor slab components, external wall components and materials installed in the gap between the external wall and the floor slab. These materials avoid the formation of fire spreading channels between floors....

The most common aluminum frame curtain wall structure with traditional (flammable materials, such as glass, aluminum or stone) partitions uses high temperature resistant mineral wool partitions. The mineral wool partition is made of slag wool or rock wool, which can withstand high temperatures up to 100 degrees. The vertical and horizontal members of the curtain wall frame around the partition are usually wrapped with mineral wool partitions (usually with a density of 96-128kg/m3). There are various ways to install mineral wool boards. Sometimes steel plates are used, but usually, the role of...

mineral wool boards, the thermal insulation performance can be improved, and the thermal insulation layers of the curtain wall can be connected to form a continuous fire separation belt. Four) Prevent the spread of smoke At the fire scene, smoke is a fatal factor. The correct fire-proof sealing system for interlayer seams can help reduce the spread of smoke. Usually, the insulation layer of the curtain wall structure is provided with aluminum foil at the separation zone. In addition, the fireproof sealing layer or fireproof sealing glue is used as a continuous component to block the spread of...

buildings for production and life. Typical fire-proof sealing products usually (before they are sold) need to be tested tens of thousands of times under different working conditions according to relevant regulations, and the relevant performance test reports confirm that they can be used in various specific situations. Using these products, in the case of no increase in construction costs, in addition to playing the role of fire and flame retardant, but also can achieve the effects of heat preservation, energy saving, moisture prevention, fog prevention and sound insulation.
