[0015] In order to solve the problem that once the temperature is too high due to the fire in the building, the net shell structure building is prone to deformation and collapse, the present application provides a fireproof system for aluminum structure building and a construction method thereof. The fireproof system for aluminum structure building and the construction method thereof are further described below in combination with the drawings.
[0016] Referring to Figs. 1-2 The fireproof system for aluminum structure building comprises: The fireproof coating is coated on the surface of the aluminum rod 1. The atomizing spraying system comprises a water pipeline 3 and a plurality of atomizing nozzles 4, the plurality of atomizing nozzles 4 are respectively fixed on a plurality of fixed discs 2, and the water pipeline 3 is in communication with all the atomizing nozzles 4 and is fixed on the aluminum rod 1. The water supply system is used for supplying water to the water pipeline 3 to realize the spraying of all the atomizing nozzles 4. The temperature detection member is used for detecting the temperature around the net shell structure to: send a first feedback signal when the detected temperature is greater than a first set value, send a second feedback signal when the detected temperature is less than a second set value, and the first set value is less than the melting point temperature of the aluminum rod 1 and greater than the second set value; and The control device is used for: controlling the water supply system to supply water to the water pipeline 3 to realize the spraying of the atomizing nozzles 4 after obtaining the first feedback signal, and controlling the water supply system to stop supplying water to realize the stop of the spraying of the atomizing nozzles 4 after obtaining the second feedback signal; the water supply system and the temperature detection member are connected with the control device.
[0017] The fireproof coating coated on the surface of the aluminum rod 1 can play a fireproof effect; the temperature detection member monitors the temperature of the environment around the net shell structure, and once the temperature is greater than the first set value, a first feedback signal can be sent, and when the control device obtains the first feedback signal, the water supply system is controlled to supply water to the water pipeline 3 to realize the spraying of the atomizing nozzles 4, so as to reduce the temperature of the environment around the net shell structure and avoid the deformation of the aluminum rod 1 due to the too high temperature.
[0018] The alarm is connected with the control device to: control the alarm to alarm when the control device obtains the first feedback signal, and control the alarm to stop alarming when the control device obtains the second feedback signal.
[0019] By adopting the above design, when a fire occurs, the temperature detection device sends a first feedback signal when it detects that the temperature of the environment around the mesh shell structure is greater than the first set temperature value. After obtaining the first feedback signal, the control device controls the water supply system to supply water to the water pipeline 3 so that the atomizing nozzle 4 can spray water. At the same time, it controls the alarm to sound an alarm, which serves as a warning.
[0020] The temperature sensing element is a temperature-sensing cable, which is fixed to the mesh shell structure.
[0021] By adopting the above design, the temperature of the environment surrounding the mesh shell structure can be detected by temperature-sensing cables without being affected by smoke and dust in the air, thus ensuring the accuracy of the detection.
[0022] A construction method for a fire protection system for aluminum structure buildings, characterized by comprising the following steps: S1. After each aluminum rod 1 is installed, apply a layer of fire-retardant coating to the surface of the aluminum rod 1. S2. Provide multiple atomizing nozzles 4 and fix the multiple atomizing nozzles 4 on multiple fixing plates 2 respectively. Provide a water supply pipe 3, connect the water supply pipe 3 to all the atomizing nozzles 4 and fix it on the aluminum rod 1. S3. Provide a water supply system and connect the water supply system to the water pipeline 3; S4. Provide a temperature sensing element and fix the temperature sensing element to the mesh shell structure; S5. Provide a control device and connect the control device to the water supply system and temperature detection device.
[0023] Before applying a fire-retardant coating to the surface of the aluminum rod 1, the surface of the aluminum rod 1 must be cleaned.
[0024] By adopting the above design, cleaning the surface of the aluminum rod 1 before applying the fire-retardant coating can improve the adhesion of the subsequent coating, thus ensuring long-term use.
[0025] The specific steps for applying a fire-retardant coating to the surface of aluminum rod 1 include: Provide a spraying device, and keep the nozzle of the spraying device perpendicular to the surface of the aluminum rod 1 to be sprayed; Start the spraying equipment and move the nozzle in a direction parallel to the surface of the aluminum rod 1 to be sprayed.
[0026] Specifically, in this embodiment, when spraying the external corner of the aluminum rod 1, the coating can be applied vertically from top to bottom or from left to right, and then applied horizontally; when spraying the internal corner of the aluminum rod 1, the coating should be applied vertically from top to bottom from both sides of the corner, and then applied horizontally. By adopting the above design, we can avoid sagging and cracking caused by excessive thickness in a single coat, as well as avoid quality problems such as bubbles and cracks during the spraying process.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
