Description

Technical Field

[0001] This utility model relates to the field of underground garage fireproof partition drainage technology, and in particular to a novel prefabricated component integrating fireproof partition drainage. Background Technology

[0002] With the continuous construction of underground parking garages in various buildings such as commercial complexes, office buildings, and civil buildings, fire compartments will be divided, forming independent fire protection units through components such as firewalls and fireproof roller shutters to ensure fire control.

[0003] As the lifeblood of a building, the drainage system needs to run through multiple zones to achieve gravity drainage. If the drainage ditches of fire compartments are not connected, each zone needs to have its own drainage system, resulting in unnecessary equipment redundancy, wasting investment and increasing equipment maintenance workload.

[0004] If the drainage ditches of each fire compartment are directly connected without effective protective measures, it will cause the drainage ditches to form continuous through holes at the fireproof partitions, which will damage the airtightness of the partitions. High-temperature smoke and flames will connect with each other across the fire compartments along the ditches, causing the fireproof and smoke-proof partitions to fail and leading to the spread of fire. Therefore, this utility model provides a new type of prefabricated component that integrates fireproof partition drainage. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model discloses a novel prefabricated component integrating fireproof partition and drainage, comprising a fireproof partition, a drainage ditch, and a prefabricated component. The prefabricated component includes two symmetrically distributed prefabricated water collection pits for storing fireproof water. The two prefabricated water collection pits are connected by a connecting component, which is encased in concrete and is entirely a prefabricated component. Both prefabricated water collection pits are equipped with a grating cover for preventing the accumulation of waste.

[0006] Furthermore, the drainage ditch is located above the two prefabricated sump pits and is connected to the two prefabricated sump pits. The fireproof partition is located above the drainage ditch and is positioned in the middle of the two prefabricated sump pits, separating the drainage ditch.

[0007] Furthermore, the connecting component includes a thin-walled plastic pipe and a thermal expansion fire-resistant barrier device. The thermal expansion fire-resistant barrier device is fixedly installed in the middle of the thin-walled plastic pipe. Both ends of the thin-walled plastic pipe are respectively connected to two prefabricated water collection pits. When heated, the thermal expansion fire-resistant barrier device will expand inward and squeeze the thin-walled plastic pipe.

[0008] Furthermore, a water loss sensor for real-time monitoring of the water level in the prefabricated water collection pit is fixedly installed at one end of the thin-walled plastic tube that extends into the prefabricated water collection pit.

[0009] The advantages of this utility model compared with the prior art are: 1. The present invention provides a novel prefabricated component for fireproof partition drainage, which constructs a drainage system spanning the fireproof partition through key components such as integrated components and water loss sensors, while maintaining effective fireproof isolation on both sides of the fireproof partition.

[0010] 2. The novel fireproof partition and drainage integrated prefabricated component provided by this utility model is prefabricated as a whole, which makes on-site installation simple and convenient, significantly optimizes the construction process, reduces on-site operation time, and can effectively connect the building drainage network.

[0011] 3. In the novel fireproof partition and drainage integrated prefabricated component provided by this utility model, a water loss sensor is installed inside the device to monitor the water loss status of the sump in real time. When the sump is in a water loss state and the water seal is actually broken, an alarm signal will be issued to remind the staff or to link the automatic equipment to perform water replenishment operation.

[0012] 4. The novel fireproof partition and drainage integrated prefabricated component provided by this utility model effectively crosses the fireproof partition through the integrated prefabricated component, and can effectively connect the drainage system of the entire building. Compared with the traditional approach of designing drainage schemes separately for different fire compartments, this solution not only significantly reduces the initial investment, but also greatly reduces the later maintenance costs.

[0019] The present invention will be further described in detail below with reference to the embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0020] Example: Figures 1-5 As shown, a novel prefabricated component integrating fireproof partition and drainage includes a fireproof partition 5, a drainage ditch 6, and prefabricated components. The prefabricated components include two symmetrically distributed prefabricated water collection pits 1 for storing fireproof water. The two prefabricated water collection pits 1 are connected by a connecting component. Each of the two prefabricated water collection pits 1 is provided with a grid cover plate 4 for blocking garbage. The drainage ditch 6 is located above the two prefabricated water collection pits 1 and is connected to the two prefabricated water collection pits 1. The fireproof partition 5 is located above the drainage ditch 6 and is positioned in the middle of the two prefabricated water collection pits 1, separating the drainage ditch 6.

[0021] The connecting component includes a thin-walled plastic tube 2 and a thermal expansion fire-resistant barrier device 3. The thermal expansion fire-resistant barrier device 3 is fixedly installed in the middle of the thin-walled plastic tube 2. Both ends of the thin-walled plastic tube 2 are respectively connected to two prefabricated water collection pits 1. When heated, the thermal expansion fire-resistant barrier device 3 will expand inward and squeeze the thin-walled plastic tube 2. A water loss sensor 7 for real-time monitoring of the water level in the prefabricated water collection pit 1 is fixedly installed at one end of the prefabricated water collection pit 1.

[0022] Under normal circumstances, the water level in the prefabricated sump 1 is high. The thin-walled plastic pipe 2 ensures the connection between the prefabricated sump 1 on both sides of the fireproof partition 5. Wastewater in the prefabricated sump 1 on one side of the fireproof partition 5 can be discharged to the prefabricated sump 1 on the other side through the connecting component. When a fire occurs on one side of the fireproof partition 5, the prefabricated sump 1 on that side acts as a temporary water seal to prevent fire and smoke from the fire-affected side from spreading to the non-fire-affected side. When the fire spreads, the water in the prefabricated sump 1 on the fire-affected side evaporates, and thermal expansion occurs. The expansion fire barrier device 3 activates its expansion mechanism when heated, quickly crushing the thin-walled plastic pipe 2 and rapidly filling the gap between the pipe wall and the structure. This establishes a sealing system equivalent to the fire resistance limit of the building components, preventing the spread of smoke and fire to different zones. At the same time, the water loss sensor 7 monitors the water loss status in the prefabricated water collection pit 1 in real time. When the prefabricated water collection pit 1 on the side where the fire occurs is in a state of water loss and the water seal is actually broken, an alarm signal will be triggered. The water loss sensor 7 will transmit the signal to the outside to remind staff or link the external automatic water replenishment equipment to perform water replenishment operations.

[0023] Furthermore, it should be noted that the shapes and names of the components in the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structures, features, and principles described in this utility model are included within the protection scope of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the structure of this utility model or exceed the scope defined by the claims, they should all fall within the protection scope of this utility model.
