Description

Technical Field

[0001] This utility model relates to the field of building fire protection technology, and in particular to a fireproof sealing device between a firewall and a steel structure. Background Technology

[0002] In the construction industry, a firewall is a non-combustible wall with a fire resistance rating of not less than three hours, designed to prevent the spread of fire to adjacent areas. It is a crucial partitioning component used to divide fire compartments or prevent the spread of fire between buildings. When pipes and cables are run through firewalls, fire-stopping technology is typically required to prevent the fire from spreading to the other side of the firewall. Fire-stopping is used to seal various openings formed when cables, air ducts, oil pipes, and gas pipes pass through walls and floors, as well as to create fire-resistant partitions for cable trays, preventing the spread of fire through these openings and gaps.

[0003] When firewalls intersect with steel structural members, traditional fire-resistant sealing materials such as mineral wool and calcium silicate boards often suffer from problems such as inadequate sealing, easy detachment, and insufficient fire resistance time. Especially at high temperatures, these materials may fail rapidly, allowing fire to spread quickly through the gaps.

[0004] In view of the above reasons, this utility model proposes a fireproof sealing device between a firewall and a steel structure to solve the above technical problems. Utility Model Content

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1 As shown, this utility model provides a fireproof sealing device between a firewall and a steel structure, comprising: an inner sealing layer 2, an intumescent fireproof sealing coating 3, and a multi-layer high-temperature resistant composite material shell 4 arranged in a ring from the inside to the outside between the steel structure member 1 and the firewall, wherein the multi-layer high-temperature resistant composite material shell 4 is provided with a locking structure 5 that is fastened to its outer periphery.

[0030] Specifically, the inner sealing layer 2 is an aerogel sealing layer, which can fit tightly with the steel structure member 1 and the firewall to achieve a good sealing effect and avoid gaps that would prevent the spread of fire.

[0031] The intumescent fire-retardant sealing coating 3 is an intumescent fire-retardant coating for steel structures that is uniformly applied to the outer periphery of the inner sealing layer. The intumescent fire-retardant coating for steel structures contains at least a high molecular weight organic resin, a film-forming aid, an intumescent flame-retardant system, fillers, and additives. This material is solid or semi-solid at room temperature, but when exposed to high temperatures (usually reaching a certain temperature threshold), it can rapidly expand several times or even tens of times, tightly adhering to the gap between the steel structure members 1 and the firewall, forming an effective fire barrier.

[0032] In this embodiment, the high-temperature resistant composite material shell 4 has three layers, and the locking structure 5 is disposed between the inner high-temperature resistant composite material shell 4 and the middle high-temperature resistant composite material shell 4. The high-temperature resistant composite material shell 4 is made of high-strength, high-temperature resistant ceramic fiber composite, which can ensure that the structure can still maintain its integrity in high-temperature environments.

[0033] In this embodiment, the locking structure 5 is a metal retaining ring. A latching assembly 6 is provided at the joint of the metal retaining ring, and the latching assembly 6 is used to adjust the tightness of the metal retaining ring to accommodate different gaps between the steel structure member 1 and the firewall. The latching assembly 6 includes a groove at one end of the metal retaining ring and multiple spaced protrusions at the other end. The other end of the metal retaining ring passes through the groove and is secured by engaging with the protrusions.

[0034] The steel structure members are hollow members, and their inner holes are used to lay pipes or cables. By installing fireproof sealing devices on the outside, the pipes and cables can also be prevented from being damaged by fire.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
