Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment, specifically a fire sprinkler system for building construction. Background Technology

[0002] Fire sprinkler systems are a core component of building fire protection systems, primarily used for automatic fire control and extinguishing in the early stages of a fire. The main structure consists of sprinklers, water pipes, and mounting brackets. They are supplied with water from the outside and can be triggered by thermal elements or in conjunction with smoke sensors. They are an essential part of fire protection during building construction.

[0003] Publication number CN219149099U discloses a fire sprinkler system, relating to the field of fire safety technology. It includes an adjusting mechanism, sprinkler heads, a drain pipe, and a transmission pipe, with the transmission pipes symmetrically spaced. This utility model has a reasonable structure. Thanks to the adjusting mechanism, the sprinkler head's application range is not limited to one position. As the transmission pipe rises and falls, the fixed pipe and the transmission pipe extend and retract, causing the sprinkler head to move up or down, effectively preventing contact with roof wiring and ensuring the sprinkler head maintains a safe spraying position, thus improving fire safety. While the aforementioned fire sprinkler system can adjust the sprinkler head position, it cannot adjust the sprinkler head installation spacing. During installation, fixed-specification installation pipes must be selected, resulting in low adaptability. Utility Model Content

[0004] The purpose of this utility model is to provide a fire sprinkler system for building construction to solve the technical problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fire sprinkler system for building construction includes a water pipe with several adjustable sprinkler components installed at the bottom. Each adjustable sprinkler component includes an adapter sleeve, with a sprinkler head threadedly connected to the center of the bottom of the adapter sleeve. The inner walls on both sides of the adapter sleeve have slots near the top. Marking protrusions are fixedly installed on the inner walls on both sides of the adapter sleeve, centered at the top of the slots. A sealing gasket is provided inside the adapter sleeve. A long, strip-shaped limiting strip matching the slots is fixedly welded axially to the outer wall of the water pipe. Suspension components are installed at both ends of the top of the water pipe.

[0007] Specifically, it facilitates the installation and adjustment of the sprinkler head position according to needs. The adapter sleeve and water pipe are sealed with a sealing gasket to prevent leakage. When a fire occurs, the ambient temperature rises rapidly, the heat-sensitive element of the sprinkler head breaks, forming a water flow of a specific shape to extinguish the initial fire or suppress the spread of the fire.

[0008] Preferably, the sealing gasket is made of high-temperature resistant rubber and is located between two slots. The adapter sleeve is connected to the water pipe through the slots and the limiting strip.

[0009] Specifically, it facilitates the adjustment of the sprinkler head position, and the installation of the sprinkler head can be completed without selecting the corresponding water pipe, making it convenient for the installation and replacement of the sprinkler head.

[0010] Preferably, flanges are fixedly installed at both ends of the water pipe.

[0011] Specifically, this design aims to prevent leaks and facilitate the interconnection and installation of multiple water pipes.

[0012] Preferably, the suspension assembly includes an outer tube, the top of which is movably connected to a base.

[0013] Specifically, it is designed to adapt to different installation angles, ensuring that the outer sleeve is always vertical.

[0014] Preferably, the suspension assembly further includes a slider disposed inside the outer sleeve, with a damper fixedly installed at the bottom of the slider, and the slider is connected to the outer sleeve by bolts and nuts.

[0015] Specifically, the height of the bottom component of the connecting rod is adjusted, and a damper is installed to improve the seismic performance of the suspension assembly.

[0016] Preferably, the suspension assembly further includes a docking sleeve fixedly installed at the bottom of the connecting rod, the bottom of the docking sleeve is provided with a docking bracket, the docking sleeve is fixedly connected to the docking sleeve by bolts, and the docking bracket is fixedly connected to the water pipe.

[0017] Specifically, remove the water pipe and the connecting fitting to facilitate pipe replacement.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1) The fire sprinkler system for this building construction is designed with adjustable sprinkler components and limiting strips. By selecting a suitable sprinkler head installation distance, corresponding through holes are drilled in the water pipe, and a mark is made on the outer wall of the water pipe at a 90° angle to the through hole. The slot is then aligned with the limiting strip and the adapter sleeve is pushed until the mark protrusion is aligned with the mark. At this point, the through hole and the sprinkler head are on the same vertical line, completing the installation of the adjustable sprinkler components. This facilitates the installation and adjustment of the sprinkler head position as needed.

[0020] 2) The fire sprinkler system in this building is constructed by setting up a suspension assembly, connecting the docking bracket with the docking sleeve, and then connecting the water pipe with the docking bracket. This facilitates the connection between the water pipe and the suspension assembly. After removing the bolts connecting the docking sleeve and the docking bracket, the water pipe and the docking bracket connected to it can be removed, making it easy to replace the water pipe.

[0037] In actual operation, according to installation requirements, select a suitable installation distance for the sprinkler head 202, drill corresponding through holes on the water pipe 1, and mark the position on the outer wall of the water pipe 1 at a 90° angle to the through hole. Then, align the slot 203 with the limiting strip 3 and push the adapter sleeve 201 until the marked protrusion 204 is aligned with the marked position. At this point, the through hole and the sprinkler head 202 are on the same vertical line, completing the installation of the adjustable sprinkler assembly 2. This facilitates the installation and adjustment of the sprinkler head 202 position as needed. The adapter sleeve 201 and the water pipe 1 are sealed with a sealing gasket 205 to prevent leakage. After assembling the water pipe 1 and the adjustable sprinkler assembly 2, the base 502 is fixedly installed on the mounting surface using expansion bolts to facilitate the fixation of the suspension assembly 5. Then, the flanges 4 of the two water pipes 1 are fixedly connected together with bolts and nuts. The two flanges 4 are sealed with a high-temperature resistant sealing ring to prevent leakage and facilitate the interconnection and installation of multiple water pipes 1. Firefighting water is delivered to each sprinkler head 202 through the water pipe 1. When a fire occurs, the ambient temperature rises rapidly, the heat-sensitive element of the sprinkler head 202 ruptures, forming a water flow of a specific shape to extinguish the initial fire or suppress the spread of the fire.
