Description

Technical Field

[0001] This utility model belongs to the field of fire protection facilities, and specifically relates to a sprinkler head structure on a double-T plate. Background Technology

[0002] As a core component of prefabricated buildings, double-T slabs offer a simpler structural form, easier construction, and more controllable costs compared to cast-in-place reinforced concrete slabs. This significantly reduces processing and installation difficulties while facilitating large-scale construction and integrated production. Furthermore, with a maximum span of up to 30m, they can flexibly meet the process requirements of various large-scale equipment in factories, thus finding widespread application in various industrial buildings. In the trend of "industrial buildings moving upstairs," double-T slabs, with their high load-bearing capacity, excellent impact resistance, high fire resistance, and convenient maintenance, effectively meet the requirements of industrial buildings for floor load-bearing capacity, structural safety, and ease of operation and maintenance.

[0003] Sprinkler heads are a type of fire extinguishing device, widely used in fire protection due to their low cost and high extinguishing efficiency. Currently, the structure of sprinkler systems installed on floor slabs can be referenced in patent CN206168654U, which discloses a suspended sprinkler system on the top of a concrete floor slab. This system involves installing a hanger frame on the floor slab, with a sprinkler pipe installed at the bottom. However, the system suffers from structural instability due to vibration and swaying caused by the water flow during spraying. Utility Model Content

[0004] This utility model provides a spray head structure on a double-T plate to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sprinkler head structure on a double T-plate includes a T-plate top plate and a T-plate rib beam. A first ring-eye threaded hanger is fixedly installed on the top plate of the T-plate. The connecting ring of the first ring-eye threaded hanger is located at the bottom end. A C4 pipe clamp is connected to the connecting ring by an upper bolt. A horizontal water pipe is inserted through the C4 pipe clamp. A second ring-eye threaded hanger is connected to the bottom end of the C4 pipe clamp by a lower bolt. The connecting ring of the second ring-eye threaded hanger is located at the top end. The connecting ring of the second ring-eye threaded hanger is connected to the bottom end of the C4 pipe clamp by a lower bolt. A ceiling fireproof board is suspended from the bottom end of the second ring-eye threaded hanger by bolts. The height of the ceiling fireproof board is higher than the bottom end of the T-plate rib beam. The ceiling fireproof board is fixedly installed on the T-plate rib beam. The bottom end of the water pipe is connected to a branch pipe located on one side of the second ring-eye threaded hanger. The branch pipe passes downward through the ceiling fireproof board and a sprinkler head is fixed at its bottom end.

[0006] By adopting the above technical solution, for the double T-plate structure, the installation of suspended fireproof panels between the T-plate ribs not only serves a decorative purpose but also fixes the branch pipes used to install sprinkler heads, ensuring the stability of the sprinkler heads, improving safety, and providing fixed support for the water pipes. This gives the entire system good structural stability, greatly reducing the complexity of the sprinkler system. Both the pipes and fireproof panels can be prefabricated in the factory, assembled, and hoisted on-site.

[0007] Preferably, a load-bearing angle steel is provided at the connection between the T-plate rib and the ceiling fireproof board. One side of the load-bearing angle steel is fixed to the T-plate rib by screws, and the other side of the load-bearing angle steel is located at the bottom end of the ceiling fireproof board and is connected to the ceiling fireproof board by screws.

[0008] By adopting the above technical solution, the connection between the ceiling fireproof board and the T-plate rib beam is firm.

[0009] Preferably, the space between the fireproof ceiling board and the T-plate ribs is filled with sealant.

[0010] By adopting the above technical solution, good sealing performance is achieved.

[0011] Preferably, the bottom end of the branch pipe has a tapered transition that is wider at the top and narrower at the bottom, the ceiling fireproof board has a mating tapered surface that matches the tapered transition, and the sprinkler head is installed at the bottom end of the tapered transition.

[0012] By adopting the above technical solution, it is possible to achieve a good fit, good bonding, and a robust structure.

[0013] Preferably, the top of the sprinkler head is fixed with a support plate that fits against the bottom of the ceiling fireproof board.

[0014] By adopting the above technical solution, the fireproof ceiling board can be supported.

[0015] Preferably, the distance between the branch pipe and the second annular threaded hanger is less than 400mm.

[0016] By adopting the above technical solutions, the structural stability is higher when the distance is relatively close.

[0017] Preferably, the annular threaded rod passes through the top plate of the T-plate, and the annular threaded rod is threaded with a wing bolt located at the top of the top plate of the T-plate.

[0018] By adopting the above technical solution, the ring-eye threaded hanger can be installed relatively easily.

[0019] The beneficial effects of this utility model are as follows: For the double T-plate structure, the installation of the ceiling fireproof board between the T-plate ribs not only serves a decorative purpose, but also fixes the branch pipes used to install the sprinkler heads, ensuring the stability of the sprinkler heads, improving safety, and providing fixed support for the water pipes, giving the entire system good structural stability, greatly reducing the complexity of the sprinkler system, and allowing the pipes and fireproof boards to be prefabricated, assembled, and hoisted on site.
