Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a gas-extinguishing pressure-bearing suspended ceiling and a gas-extinguishing room. Background Technology

[0002] For specific areas such as data centers, archives, and museums, gaseous fire suppression systems need to be designed and installed to protect them from fire damage; these rooms are called gaseous fire suppression rooms. To ensure the effective operation of the gaseous fire suppression system, there are certain volume requirements for the room. When the room volume is too large, it is necessary to reduce the room's ceiling height to meet the volume requirements, typically achieved by installing a pressurized suspended ceiling for the gaseous fire suppression system.

[0003] Currently, pressurized suspended ceilings for gas extinguishing systems typically use a joist to fix ceiling panels below the ceiling slab. The ceiling panels, located below the joists, can also serve as decorative panels. For the electromechanical wiring used in gas extinguishing rooms for lighting and smoke detection systems, it needs to be fixed to the ceiling slab. To connect these wiring to the lights and smoke detectors, holes need to be drilled in the ceiling panels for the wiring to pass through. These holes affect the sealing of the ceiling panels, requiring sealing after the wiring is installed. However, the numerous and irregularly shaped holes make sealing difficult and compromises the sealing effect. When the gas extinguishing system is activated, the extinguishing gas is prone to leakage, compromising the extinguishing effectiveness.

[0004] Therefore, how to solve the problem of sealing difficulties and inability to guarantee the sealing effect after laying electromechanical pipelines in gas-extinguished pressure-bearing ceilings has become an important technical problem to be solved by those skilled in the art.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0034] The following is combined Figures 1 to 3 This invention describes the gas-extinguishing pressure-bearing suspended ceiling.

[0035] like Figures 1 to 3 As shown, the gas-extinguishing pressure-bearing ceiling provided in this embodiment of the utility model includes a supporting keel 1, a ceiling panel 3, and a mounting bracket.

[0036] Specifically, the supporting keel 1 is used to fix the target floor slab 2 below, providing support for the ceiling panel 3 and the mounting bracket.

[0037] The ceiling panel 3 is installed above the supporting keel 1 and is fixedly connected to the supporting keel 1. The ceiling panel 3 is used to divide the room so that the space below the ceiling panel 3 meets the requirements.

[0038] The mounting bracket is located below the supporting keel 1 and is fixedly connected to the supporting keel 1. The mounting bracket is used to install the electromechanical pipeline 4.

[0039] This configuration places the ceiling panel 3 above the supporting keel 1, with the supporting keel 1 exposed below the ceiling panel 3, providing a support point for the mounting bracket. The mounting bracket, electromechanical pipelines 4, and the light fixtures, sprinkler heads, air conditioning vents, smoke detectors, etc., that the electromechanical pipelines 4 need to connect to are all located below the supporting keel. The electromechanical pipelines 4 do not need to penetrate the ceiling panel 3 vertically, eliminating the need for drilling holes in the ceiling panel 3. This avoids sealing operations at drilling locations and does not damage the structure of the ceiling panel 3, ensuring its integrity. This improves the sealing performance of the gas-fired pressure-bearing ceiling and solves the problem of sealing difficulties and inconsistent sealing effects after the installation of electromechanical pipelines in related technologies. When the gas extinguishing system in the room is activated, leakage of the extinguishing gas is prevented, improving the extinguishing speed and effectiveness.

[0040] The material of the aforementioned supporting keel 1 can be, but is not limited to, steel.

[0041] In this embodiment of the utility model, the mounting bracket includes a pipe 5, which has an internal accommodating space for threading electromechanical cables 4. The axis of the pipe 5 is parallel to the plane of the supporting keel 1, and the pipe 5 is fixedly connected to the supporting keel 1.

[0042] The cross-sectional shape of the aforementioned pipe fitting 5 may be, but is not limited to, circular, rectangular, etc. No specific limitation is made here regarding the cross-sectional shape of the pipe fitting 5.

[0043] In some embodiments, pipe clamps 6 are used to connect the pipe fitting 5 to the supporting keel 1. Specifically, the gas-extinguishing pressure-bearing ceiling also includes pipe clamps 6 and first fasteners 7, as shown in the figure. Figure 2 .

[0044] The pipe clamp 6 is curved and can be either a C-shaped or a U-shaped pipe clamp. The pipe clamp 6 is encircled around the outside of the pipe fitting 5. The supporting keel 1 is provided with a first connection hole. Each end of the pipe clamp 6 is provided with a corresponding first connection hole, and both ends of the pipe clamp 6 pass through the first connection hole.

[0045] The first fastener 7 is located above the supporting keel 1. Each end of the pipe clamp 6 is provided with a corresponding first fastener 7, and the first fastener 7 is threadedly connected to the end of the pipe clamp 6. The pipe fitting 5 is located within the space enclosed by the pipe clamp 6 and the supporting keel 1, and the pipe fitting 5 is fixedly connected to the supporting keel 1 by the pipe clamp 6 and the first fastener 7.

[0046] The end of the pipe clamp 6 is provided with an external thread, and the first fastener 7 is a nut that can be adapted to the external thread.

[0047] In other embodiments, a hanger structure is used to connect the pipe 5 to the supporting keel 1. Specifically, the gas-extinguishing pressure-bearing ceiling also includes a first hanger 8 and a second fastener 9, such as... Figure 3 As shown.

[0048] The first hanger 8 is disposed between the pipe fitting 5 and the supporting keel 1. The supporting keel 1 is provided with a second connecting hole. The first end of the first hanger 8 passes through the second connecting hole. The second fastener 9 is located above the supporting keel 1 and is threadedly connected to the first end of the first hanger 8.

[0049] An external thread is provided at the first end of the first rod 8, and the second fastener 9 is a nut that can be adapted to the external thread.

[0050] The second end of the first hanger 8 is connected to the pipe fitting 5. Specifically, a connecting lug is provided on the side of the pipe fitting 5 near the supporting keel 1, and a connecting ear is provided at the second end of the first hanger 8. The connecting bolt 11 passes through the connecting lug and the connecting ear and is tightened with a nut to connect the second end of the first hanger 8 to the pipe fitting 5.

[0051] In this embodiment of the invention, the air-extinguishing pressure-bearing ceiling also includes a second hanger 10, which is disposed above the supporting keel 1. The first end of the second hanger 10 is fixedly connected to the target floor slab 2, and the second end of the second hanger 10 is fixedly connected to the supporting keel 1, so as to fix the supporting keel 1 below the target floor slab 2.

[0052] For the connection structure between the first end of the second hanger 10 and the target floor slab 2, an expansion bolt can be installed on the target floor slab 2, and a threaded hole can be installed at the first end of the second hanger 10, so that the first end of the second hanger 10 is threadedly connected to the expansion bolt.

[0053] For the connection structure between the second end of the second hanger 10 and the supporting keel 1, a third connecting hole can be provided on the supporting keel 1, allowing the second end of the second hanger 10 to pass through the third connecting hole. An external thread is provided at the second end of the second hanger 10, and a nut is threadedly connected to the second hanger 10 below the supporting keel 1.

[0054] In this embodiment of the utility model, after the ceiling panel 3 is placed above the supporting keel 1, the ceiling panel 3 and the supporting keel 1 are fixedly connected together using aircraft nails or expansion screws, which increases the connection strength between the ceiling panel 3 and the supporting keel 1 and prevents the ceiling panel 3 from detaching from the supporting keel 1 when the pressure in the room is too high, thereby ensuring the airtightness of the gas-extinguishing pressure-bearing ceiling.

[0055] Aircraft rivets, also known as aviation rivets or high-strength rivets, possess high strength, corrosion resistance, and excellent fatigue resistance. Using aircraft rivets to connect the ceiling panel 3 to the supporting keel 1 allows the ceiling panel 3 to withstand higher loads and impacts, and it is less prone to breakage or failure during long-term use. This helps improve the reliability and stability of the gas-extinguishing pressure-bearing ceiling, ensures the sealing of the gas-extinguishing pressure-bearing ceiling, and extends the service life of the gas-extinguishing pressure-bearing ceiling.

[0056] In this embodiment of the utility model, the supporting keel 1 is set in a grid shape, which can create a simple decorative style, increase the sense of space, and make it more convenient to arrange and fix the bracket.

[0057] In this embodiment, the ceiling panel 3 is provided in at least two layers, with each layer of ceiling panel 3 stacked on top of the others, and each layer of ceiling panel 3 is fixedly connected to the supporting keel 1. Increasing the number of ceiling panels 3 can increase the strength and pressure-bearing capacity of the ceiling panels 3, thereby improving the pressure-bearing capacity of the air-extinguished pressure-bearing ceiling.

[0058] Specifically, two layers of ceiling panels 3 can be installed, each with a thickness of 12 mm.

[0059] In this embodiment, gypsum board or cement pressure board is selected as the ceiling panel 3.

[0060] On the other hand, this utility model embodiment also provides a gas extinguishing room, including the gas extinguishing pressure-bearing ceiling provided in any of the above embodiments. The gas extinguishing pressure-bearing ceiling provided in any of the above embodiments does not require drilling holes in the ceiling panel 3 during installation, and has excellent sealing performance. Therefore, the gas extinguishing room in this embodiment has the advantages of good fire extinguishing effect and fast fire extinguishing speed. The derivation process of the beneficial effects of the gas extinguishing room in this utility model embodiment is largely similar to the derivation process of the beneficial effects of the gas extinguishing pressure-bearing ceiling described above, and therefore will not be repeated here.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
