Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof steel, and particularly relates to a fireproof steel structure for construction. Background Art

[0002] Fireproof steel structure for construction is a design and implementation method of structural engineering to provide fire protection for buildings. It is usually used in buildings that require higher fire protection requirements such as high-rise buildings, commercial buildings and public buildings. Fireproof steel structure for construction generally uses special steel materials and design methods to provide longer-lasting and reliable protection. The design of fireproof steel structure takes into account various factors such as the fire resistance of the material, the stability of the structure and avoiding the spread of fire. Fire-retardant coatings, flame-retardant materials and thermal insulation materials are also widely used on these structures to enhance their fire resistance.

[0003] In the existing patent literature, there is a patent for "A fireproof steel structure for building" with an application date of 2019.10.14 and an authorization announcement number of CN 212153683U. This patent mainly achieves fire prevention and fire extinguishing by setting up sprinkler pipes.

[0004] However, the implementation of this patent requires the laying of a large number of water pipes and water-displacing devices, etc., which results in a high investment cost. It is not suitable for implementation in high-rise buildings, resulting in low application flexibility.

[0005] Therefore, in view of the shortcomings of the above-mentioned scheme in actual production and implementation, it has been revised and improved. At the same time, in the spirit and concept of seeking excellence, with the assistance of professional knowledge and experience, and after many ingenuity and experiments, the present utility model was created, and a fire-proof steel structure for construction is provided to solve the problem. Utility Model Content

[0006] The utility model provides a fireproof steel structure for building, which solves the problems in the prior art.

[0007] The technical solution of the utility model is achieved in this way:

[0008] A fireproof steel structure for construction comprises a steel frame with a hollow cavity formed inside the steel frame; at least one fire extinguishing airbag is fixedly installed in the hollow cavity, the fire extinguishing airbag is filled with high-pressure gas and fire extinguishing powder, and at least one fire extinguishing port is formed from the inside to the outside of the hollow cavity, and the fire extinguishing port corresponds to the position of the fire extinguishing airbag.

[0009] By adopting the above technical solution and setting up a fire extinguishing airbag, when encountering a fire, the fire will burn the fire extinguishing airbag through the fire extinguishing port. The fire extinguishing airbag will instantly explode under the action of the high-pressure gas inside it at the moment of contact with the fire, driving the powdered fire extinguishing materials such as the fire extinguishing powder inside it to spread through the fire extinguishing port. The fire extinguishing materials are evenly spread to the fire, which can extinguish the surrounding fire, thereby achieving the purpose of fire extinguishing and protection.

[0010] As a preferred embodiment, the outer surface of the steel frame is covered with a fire-resistant layer.

[0011] By adopting the above technical solution, the fire resistance of the steel frame is further improved.

[0012] As a preferred implementation, the fire extinguishing airbag is suspended and mounted on a positioning frame, and the positioning frame is fixedly connected to the inner wall of the hollow cavity.

[0013] By adopting the above technical solution, the stability of the fire extinguishing airbag is further improved.

[0014] As a preferred embodiment, a plurality of blocking columns are fixedly connected to the fire extinguishing port toward the center of the circle, and the fire extinguishing airbag is further blocked by the blocking columns.

[0015] By adopting the above technical solution, the fire extinguishing airbag is blocked by the blocking column, which does not hinder the fire extinguishing airbag from extinguishing the fire from the fire extinguishing port, and at the same time can block the fire extinguishing airbag to avoid the fire extinguishing airbag being exposed and causing safety problems.

[0016] As a preferred implementation, the end surface of the blocking column is an arc surface.

[0017] By adopting the above technical solution, it is prevented that the end of the blocking column cuts the fire extinguishing airbag.

[0018] As a preferred implementation, at least one anti-touch component is fixedly connected to the outside of the steel frame, the anti-touch component corresponds to the position of the fire extinguishing port, and the anti-touch component can completely block the fire extinguishing port.

[0019] By adopting the above technical solution and setting up an anti-touch component, the fire extinguishing airbag can be further blocked, the anti-touch property can be further improved, thereby improving safety.

[0020] As a preferred implementation, the anti-touch component includes a protective shell, and an opening of the protective shell is blocked with an anti-touch cover.

[0021] By adopting the above technical solution, the protection shell and the anti-touch cover are wrapped together to achieve touch protection.

[0022] As a preferred embodiment, at least one guide shaft fixed on the steel frame is provided in the protective shell, the anti-touch cover is slidably mounted on the guide shaft, and a spring is mounted on the guide shaft to push the anti-touch cover outward.

[0023] By adopting the above technical solution, the anti-touch cover is ejected by the spring, thereby increasing the speed at which the anti-touch cover falls off.

[0024] As a preferred embodiment, a soluble solid is filled between the protective shell and the anti-touch cover, wherein the soluble solid is beeswax or the like, and the anti-touch cover can be bonded and fixed by the soluble solid.

[0025] By adopting the above technical solution, when a fire occurs, the soluble solid can be quickly melted by heat, and then promote the anti-touch cover to fall off.

[0026] As a preferred embodiment, the steel frame can be detachably installed on the building wall.

[0027] By adopting the above technical solution, the fireproof steel structure can be disassembled and replaced after use, which makes it more flexible in use and suitable for high-rise building walls.

[0028] After adopting the above technical solution, the beneficial effects of the utility model are:

[0029] 1. By setting up a fire extinguishing airbag, when encountering a fire, the fire will burn the fire extinguishing airbag through the fire extinguishing port. The fire extinguishing airbag will instantly explode under the action of the high-pressure gas inside it at the moment of contact with the fire, driving the powdered fire extinguishing materials such as the fire extinguishing powder inside it to spread through the fire extinguishing port. The fire extinguishing materials are evenly spread to the fire, which can extinguish the surrounding fire, thereby achieving the purpose of fire extinguishing and protection;

[0030] 2. The fireproof steel structure can be disassembled and replaced after use, which makes it more flexible to use and suitable for high-rise building walls. BRIEF DESCRIPTION OF THE DRAWINGS
