Description

Technical Field

[0001] The present application relates to the field of suspended ceilings, and in particular to a broken-line explosion-proof suspended ceiling. Background Art

[0002] Factories with explosion hazards should be equipped with pressure relief facilities. If the explosion hazardous area is located on the top floor of the building, lightweight roofs or lightweight exterior walls are generally used in the design. However, for non-top floors in multi-story buildings, only the exterior walls can be used for pressure relief. Due to the limitations of the layout of process equipment, there are often situations where the room is deep and large in volume, but the explosion relief area of ​​the exterior wall is insufficient, which can easily lead to low explosion-proofness of the factory building.

[0003] There is an urgent need for a suspended ceiling that can increase the explosion-proof area of ​​the factory building. Utility Model Content

[0004] In order to increase the explosion-proof area of ​​a factory building, the present application provides a broken-line explosion-proof suspended ceiling.

[0005] The present application provides a broken-line explosion-proof ceiling, which adopts the following technical solution:

[0006] A broken-line explosion-proof ceiling comprises a ceiling and a connecting device, wherein the ceiling comprises a horizontal plate and a vertical plate, wherein the horizontal plate is arranged on the vertical plate, and the connecting device comprises a horizontal connector and a vertical connector, wherein the horizontal connector is used to connect the horizontal plate to a wall, and the vertical connector is used to connect the vertical plate to a roof, and the vertical plate, the horizontal plate, the wall and the roof form a cavity for absorbing shock waves and pressure during a factory explosion.

[0007] By adopting the above technical solution, the horizontal plate is arranged on the vertical plate, and the horizontal plate is arranged on the wall through the horizontal connecting piece, and the vertical plate is arranged on the roof through the vertical connecting piece, so that the roof, the wall, the vertical plate and the horizontal plate form a cavity, and when an explosion occurs on the floor with a suspended ceiling, the horizontal plate is deformed and ruptured, and the explosion energy is guided to the top of the suspended ceiling, thereby avoiding direct damage to the equipment and personnel inside the factory building. Through the cooperation of the suspended ceiling and the connecting device, the explosion relief area of ​​the factory building can be increased without changing the internal layout of the factory building.

[0008] Optionally, the horizontal plate includes a plurality of horizontal bars, which are horizontally arranged and distributed along the width direction of the horizontal bars, and the horizontal bars abut against each other; the vertical plate includes a plurality of vertical bars, which correspond one-to-one to the plurality of horizontal bars, and the vertical bars are connected to the side walls of the horizontal bars by bolts.

[0009] By adopting the above technical solution, due to the different sizes of factory buildings, the areas of explosion relief required in the factory buildings are different. The horizontal plate is composed of several horizontal bars, and the vertical plate is composed of several vertical bars. Therefore, the volume of the cavity formed by the horizontal plate, the vertical plate, the wall and the roof can be changed, thereby improving the application range of the suspended ceiling.

[0010] Optionally, the horizontal connecting member includes a horizontal mounting bar, which is arranged on the wall, the length direction of the horizontal mounting bar is parallel to the width direction of the horizontal bar, and a snap-in groove is provided on the horizontal mounting bar, which is used to snap-in the side of the horizontal bar away from the vertical bar.

[0011] By adopting the above technical solution, the staff will clamp one end of the horizontal bar into the clamping groove of the horizontal mounting bar. The clamping groove can be used for clamping several horizontal bars. The horizontal mounting bar can be suitable for factories of different sizes. The installation structure of the horizontal bar and the horizontal mounting bar is simple and easy for the staff to operate.

[0012] Optionally, the vertical connecting member includes a vertical mounting bar, a plurality of clip blocks and a plurality of screw rods. The length direction of the vertical mounting bar is parallel to the length direction of the horizontal mounting bar. The plurality of clip blocks correspond one-to-one to the plurality of vertical bars. The plurality of clip blocks are distributed along the length direction of the vertical mounting bar. The clip blocks are slidably connected to the vertical mounting bar along the length direction of the horizontal bar. The plurality of screw rods correspond one-to-one to the plurality of clip blocks. The screw rods are threadedly connected to the vertical mounting bar. One end of the screw rods is rotatably connected to the clip block. The clip block is used to clip the vertical bar.

[0013] By adopting the above technical solution, since the vertical bar is connected to the horizontal bar by bolts, and the end of the horizontal bar away from the vertical bar is arranged on the horizontal mounting bar, the staff can install the end of the vertical bar away from the horizontal bar through the vertical connecting piece to complete the installation of the suspended ceiling. The staff will match the vertical bar with the card block, and the staff can rotate the screw, and the screw drives the card block to move in the direction of the vertical bar until the card block is carded to the vertical block. The vertical connecting piece has a simple structure and is easy for the staff to operate.

[0014] Optionally, a dovetail groove is provided on one side wall of the horizontal bar, and a dovetail bar is provided on the other side wall of the horizontal bar, and the dovetail groove is used for slidingly cooperating with an adjacent dovetail bar.

[0015] By adopting the above technical solution, adjacent horizontal bars cooperate with the dovetail bars through dovetail grooves, thereby improving the sealing of the cavity. During a factory explosion, the horizontal bars can be destroyed, and the shock wave of the explosion can better enter the cavity, thereby improving the riot-proof effect of the suspended ceiling.

[0016] Optionally, a plurality of anti-fall rods are provided on the horizontal mounting bar, the plurality of anti-fall rods correspond to a plurality of horizontal bars one by one, and the anti-fall rods abut against the lower end surface of the horizontal bar.

[0017] By adopting the above technical solution, a shock wave will be generated after the factory explosion, causing the horizontal bar to deform and be damaged. The horizontal bar is set to be separated from the horizontal installation bar, and the anti-fall rod reduces the occurrence of the horizontal installation bar falling to the ground, thereby reducing the horizontal bar from injuring workers or even damaging factory equipment.

[0018] Optionally, the lower end surface of the horizontal strip is coated with a fire retardant coating.

[0019] By adopting the above technical solution, a violent explosion will produce a high-temperature flame, and the fire-retardant coating is used to block the flame and delay the spread of the fire.

[0020] Optionally, a plurality of collapse grooves are provided on the horizontal bar.

[0021] By adopting the above technical solution, the crush groove is used to reduce the thickness of the horizontal strip. During an explosion, the horizontal strip with the crush groove is more easily damaged, and the shock wave of the explosion is absorbed. The crush groove improves the sensitivity of resisting the shock wave of the explosion.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The horizontal plates, vertical plates, roof and walls form a cavity to resist the shock wave during the explosion and increase the explosion relief area of ​​the plant;

[0024] 2. The horizontal plate is composed of horizontal strips, and the vertical plate is composed of vertical strips, so that the area of ​​the cavity can be adjusted according to the explosion-proof area required by the factory building, which increases the application range of the explosion-proof ceiling;

[0025] 3. Crushing grooves are used to reduce the thickness of horizontal bars. Crushing grooves make the ceiling less sensitive to shock waves. BRIEF DESCRIPTION OF THE DRAWINGS
