Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel structures, in particular to a building steel structure with fireproof function. Background Art
[0002] Steel structure is a structural material widely used in construction projects. It has high structural strength and good ductility. The steel structure itself has good compressive and seismic resistance. At the same time, steel is light in weight, has a short construction period and can be reused. However, the biggest weakness of steel structure is its low fire resistance. It cannot maintain stiffness and hardness for a long time in a high temperature environment, which poses a safety risk to building support. In the existing technology, flame retardant and water cooling methods are mostly used for fire prevention based on fire prevention principles.
[0003] Existing fireproof steel structures for buildings include the following structures: Publication No. CN218540966U discloses a fireproof steel structure for buildings, including a horizontal steel beam, an anti-blocking mechanism, and a disassembly mechanism. The lower end of the horizontal steel beam is fixedly connected to a steel column. A main water pipe is arranged in the horizontal steel beam, a three-way joint is arranged on the main water pipe, a water distribution pipe is arranged on the three-way joint, an anti-blocking mechanism is arranged in the water distribution pipe, a disassembly mechanism is arranged on the water distribution pipe, and a fire sprinkler head is arranged on the disassembly mechanism. The anti-blocking mechanism includes a filter, an impeller, a top rod, a slide, a guide rod, and a first spring. The filter is in contact with the water distribution pipe.
[0004] The above prior art often has the following problems when used:
[0005] 1. The water cooling method currently used generally uses a shower-style wide spray method to cool down the steel. However, this water cooling method not only wastes a lot of water resources, but also fails to cover the outer surface of the steel, thereby reducing the fire prevention effect and affecting the strength of the steel structure;
[0006] 2. In addition, the existing fire prevention measures for steel structures usually adopt a method of cooling the steel with water on the basis of laying fireproof materials, and protecting the steel by spraying water to cool down and prevent fire. However, when the sprinkler head is not in use, it is easy to be blocked due to the entry of dust and impurities in the external environment, and it is difficult to play a role when it is needed, affecting the stable operation of the fire prevention device. At the same time, it is inconvenient to clean the sprinkler head on a daily basis, and the maintenance cost is high. Utility Model Content

[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0024] like Figure 1 As shown, the embodiment of the utility model proposes a steel structure for building with fireproof function, including a steel frame 1, a spray assembly and a cleaning and maintenance assembly: the steel frame 1 adopts a hollow structure, and the outer surface of the steel frame 1 is coated with a thick fireproof layer material; the spray assembly includes a water pipe 2 fixedly connected to the inside of the steel frame 1, a spray pipe 3 is installed above the side wall of the steel frame 1, and the spray pipe 3 is connected to the water pipe 2. A through hole is opened on the steel frame 1, and the water pipe 2 is connected to the spray pipe 3 through a connecting pipe 10. The connecting pipe 10 passes through the side wall of the steel frame 1 through the through hole. A plurality of spray heads 4 are installed on the spray pipe 3, and the spray pipe 3 and the spray head 4 are all made of brass fireproof material;
[0025] An external water source is connected to the water pipe 2, so that the water in the water pipe 2 passes through the connecting pipe 10 and enters the sprinkler pipe 3, and then the sprinkler pipe 3 sprays water on the upper surface of the steel structure frame 1 through multiple sprinkler heads 4. It should be noted that the water pressure of the external water source does not have to be too high, and it is sufficient to reach a level where the sprinkler head 4 can discharge water normally. By setting up multiple sprinkler heads 4 for sprinkling water, the water flow can fully cover the outer surface of the steel structure frame 1, thereby improving the fire protection effect of the steel structure and ensuring the strength and hardness of the steel structure as much as possible.
[0026] like Figure 1-3 As shown, the cleaning and maintenance assembly includes a double sliding rod 5 fixedly connected to the top of the spray pipe 3, a sliding block 6 is slidably connected to the double sliding rod 5, a pull ring 11 is fixedly connected to the sliding block 6, sleeves 7 are fixedly connected to both sides of the sliding block 6, a cleaning rod 8 is slidably connected inside the sleeve 7, bristles 12 are arranged at the end of the cleaning rod 8, the bristles 12 can fit the surface of the spray head 4, and a tension spring 9 is connected between the end of the cleaning rod 8 and the inside of the sleeve 7;
[0027] When not in use daily, the fireproof steel structure can be maintained regularly. During maintenance, first let water flow through the water pipe 2, use a steel wire rope to pass through the pull ring 11, and pull the pull ring 11 by pulling the steel wire rope to drive the slider 6 to slide on the double slide rod 5, so that the slider 6 drives the sleeve 7 and the cleaning rod 8 to move synchronously. During this process, the cleaning rod 8 slidably connected to the sleeve 7 is subjected to the tension of the tension spring 9, so that the bristles 12 are tightly attached to the outer surface of the sprinkler head 4, thereby improving the scrubbing and cleaning effect, avoiding the sprinkler head 4 from being blocked when it is needed, ensuring the stable operation of the fire protection device, and facilitating the cleaning and maintenance of the sprinkler head 4.
[0028] The detailed working process of the utility model is as follows:
[0029] 1. When in use, an external water source is connected to the water pipe 2, so that the water in the water pipe 2 passes through the connecting pipe 10 and enters the spray pipe 3, and then the spray pipe 3 sprays water on the upper surface of the steel frame 1 through multiple spray heads 4. It should be noted that the water pressure of the external water source does not need to be too high, and it is sufficient to reach the level where the spray head 4 can discharge water normally. By setting multiple spray heads 4 for spraying, the water flow can fully cover the outer surface of the steel frame 1, thereby improving the fire protection effect of the steel structure and ensuring the strength and hardness of the steel structure as much as possible;
[0030] 2. When not in use daily, the fireproof steel structure can be maintained regularly. During maintenance, first let water flow through the water pipe 2, use a thin steel wire rope to pass through the pull ring 11, and pull the pull ring 11 by pulling the thin steel wire rope to drive the slider 6 to slide on the double slide rod 5, so that the slider 6 drives the sleeve 7 and the cleaning rod 8 to move synchronously. During this process, the cleaning rod 8 slidably connected to the sleeve 7 is subjected to the tension of the tension spring 9, so that the bristles 12 are tightly attached to the outer surface of the sprinkler head 4, thereby improving the scrubbing and cleaning effect, avoiding the sprinkler head 4 from being blocked when it is needed, ensuring the stable operation of the fire protection device, and facilitating the cleaning and maintenance of the sprinkler head 4.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
