Description

Technical Field

[0001] The invention relates to the technical field of building materials, and in particular to a fireproof steel structure for building. Background Art

[0002] Steel structure is a kind of non-combustible building material, which has the characteristics of earthquake resistance and bending resistance. In practical applications, steel structure can not only relatively increase the load capacity of buildings, but also meet the needs of architectural design aesthetics; therefore, steel structure is favored by the construction industry. Single-story, multi-story, skyscrapers, factories, warehouses, waiting rooms, airport lounges, etc. are all commonly made of steel structure. However, as a building material, steel structure has some unavoidable defects in fire prevention. Its mechanical properties, such as yield point, tensile strength and elastic modulus, will drop sharply due to the increase in temperature, leading to deformation. Therefore, fireproof steel structure has become an indispensable building material.

[0003] Most of the current fireproof steel structures used in buildings are only coated with a layer of fireproof layer on the outer surface. Such a layer of fireproof layer is far from enough to achieve the fire prevention function, because the effective fire prevention time of the fireproof layer is only about ten minutes. If no effective firefighting measures are taken after the time, the current fireproof steel structure will be deformed in the ultra-high temperature industrial fire, which will lead to the collapse of the entire factory building, resulting in serious losses to the factory building. The current fireproof steel structure used in buildings is far from achieving the purpose of safety in use. Summary of the invention

[0004] The purpose of the present invention is to solve the problems of poor fireproof and high temperature resistance and insufficient cooling effect in the prior art, and to propose a fireproof steel structure for construction.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A fireproof steel structure for construction comprises a fireproof steel body, a fireproof coating is arranged on the outer surface of the fireproof steel body, a thermal insulation layer is arranged on one side of the fireproof coating, a cavity pipe is opened inside the fireproof steel body, a spray pipe is arranged on the outer surface of the fireproof steel body, a first spray head is fixedly connected to one side of the spray pipe, a connecting pipe is fixedly connected to one end of the spray pipe, a second spray head is fixedly connected to the bottom end of the connecting pipe, and a gap groove is arranged at the bottom end of the second spray head.

[0008] Preferably, a delivery pipe is fixedly connected to one side of the spray pipe, and a connecting port is fixedly connected to the bottom end of the delivery pipe.

[0009] Preferably, a manual switch is provided at the top of the connection port, and an anti-slip layer is provided on the outer surface of the manual switch.

[0013] 1. The present invention provides a fireproof coating on the outer surface of the fireproof steel body, a thermal insulation layer on one side of the fireproof coating, and a cavity pipe inside the fireproof steel body, so that the fireproof steel structure can effectively prevent fire and withstand high temperatures, thereby increasing the fire resistance time. The cavity pipe can be used to load and remove coolant inside the fireproof steel structure, thereby more effectively ensuring the fireproof and high temperature resistance performance of the fireproof steel structure, providing precious time for disaster relief and fire fighting, avoiding the deformation of the steel structure due to the inability to put out the fire in time, ensuring the structural safety of the factory building, and effectively reducing losses.

[0014] 2. In the present invention, a spray pipe is arranged on the outer surface of the fireproof steel body, a first spray head is fixedly connected to one side of the spray pipe, a connecting pipe is fixedly connected to one end of the spray pipe, and a second spray head is fixedly connected to the bottom end of the connecting pipe, so that the spray pipe and the connecting pipe arranged on the outer surface of the fireproof steel structure can generate flowing water flow, and then the first spray head and the second spray head are used to spray water, so as to achieve the purpose of effectively cooling the surrounding of the steel structure, and a gap groove is arranged at the bottom end of the second spray head, and the gap groove is opened on the outer surface of the fireproof steel structure, and then a certain amount of water can be stored by using the gap groove, and the water stored on the outer surface of the steel structure can be cooled more effectively, so that the surrounding and surface of the steel structure are effectively cooled, ensuring the safe use of the steel structure in fire and greatly improving the usability.

[0015] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. The present invention can effectively prevent fire and resist high temperature by arranging a fire-retardant coating, a thermal insulation layer and a cavity pipe, thereby increasing the fire resistance time, providing precious time for disaster relief and fire fighting, avoiding the deformation of the steel structure due to the inability to put out the fire in time, ensuring the structural safety of the factory building, and effectively reducing the loss. By arranging a sprinkler pipe and a connecting pipe, a flowing water flow can be generated, thereby achieving the purpose of effectively cooling the surrounding of the steel structure. A gap groove is provided at the bottom end of the second sprinkler head, and the gap groove is opened on the outer surface of the fireproof steel structure. Then, a certain amount of water can be stored by utilizing the gap groove, and the water stored on the outer surface of the steel structure can be cooled more effectively, thereby effectively cooling the surrounding area and surface of the steel structure.
