Description

Technical Field

[0001] The utility model relates to the field of fire safety facilities, in particular to a smoke baffle cloth structure. Background Technique

[0002] The smoke baffle cloth structure is mainly used to prevent the spread of smoke generated during a fire. Currently, a counterweight bar is installed at the lowest end of the smoke baffle cloth structure. The counterweight bar is located below the smoke baffle cloth to prevent the cloth from fluttering. However, due to the absence of a blocking device, when the smoke baffle cloth structure is retracted, it collides with the ceiling finish, resulting in a large gap at the joint and making it difficult to achieve a flat finish. Moreover, in the conventional smoke baffle cloth structure, no protective cover is installed on the outermost side, or the protective cover is installed later, resulting in a poor size match and making it easy for the rolling shutter to be contaminated or damaged.

[0003] Moreover, most of the current counterweight bars are L-shaped and are only fixed with bolts, resulting in insecure installation at the bottom plate and a rough finish, which is prone to damage.

[0004] In view of this, a smoke baffle cloth structure is proposed from a practical perspective. Content of the Utility Model

[0005] The purpose of the utility model is to provide a smoke baffle cloth structure to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A smoke baffle cloth structure, which is characterized in that it is fixed below the ceiling and includes: a suspension rod, galvanized iron sheet, reel, smoke baffle cloth, and counterweight bar fixed below the ceiling. The suspension rod is fixedly connected to the galvanized iron sheet through bolts. An opening is provided at the lower end of the galvanized iron sheet. The reel is installed inside the galvanized iron sheet. The reel is rotatably connected to the smoke baffle cloth. The smoke baffle cloth moves up and down through the opening under the drive of the reel. A counterweight bar fixed below the smoke baffle cloth and a ceiling base plate used in cooperation with the counterweight bar.

[0008] Preferably, the counterweight bar is in an inverted T shape and is fixed below the smoke baffle cloth through bolts to prevent the smoke baffle cloth from fluttering.

[0009] Preferably, the ceiling base plate includes a magnesium oxychloride board and a gypsum board, and the gypsum board is arranged below the magnesium oxychloride board.

[0010] Preferably, anti-collision sticker strips are respectively installed above both ends of the counterweight bar.

[0011] The beneficial effects of the present invention are as follows: the present invention adds an inverted T-shaped counterweight strip at the lower end of the smoke barrier cloth, and enhances the overall windproof ability of the present invention by shifting the center of gravity downward, thereby preventing the smoke barrier cloth from fluttering around under the action of external forces and causing damage to other devices. Secondly, the inverted T-shaped design and the use of anti-collision strips make the smoke barrier cloth form a horizontal line with the closing part of the ceiling substrate after it is raised, making the finished ceiling surface smooth and beautiful.

[0019] See also Figures 1 - 3 ,Figure 1 This is a cross-sectional view of the present utility model.

[0020] A smoke baffle cloth structure, characterized in that it is fixed below the ceiling and includes: a suspension rod 1 fixed below the ceiling, galvanized iron sheet 2, a reel 3, a smoke baffle cloth 4, and a counterweight strip 5. The suspension rod 1 is fixedly connected to the galvanized iron sheet 2 through a bolt 9. The lower end of the galvanized iron sheet 2 is provided with an opening. A reel 3 is installed inside the galvanized iron sheet 2. The reel 3 is rotatably connected to the smoke baffle cloth 4. The smoke baffle cloth 4 moves up and down through the opening under the drive of the reel 3. The counterweight strip 5 fixed below the smoke baffle cloth 4 and a ceiling base plate used in cooperation with the counterweight strip 5.

[0021] Among them, the galvanized iron sheet 2 is used to protect the smoke baffle cloth.

[0022] Further, the counterweight strip 5 is in an inverted T shape and is fixed below the smoke baffle cloth 4 through a bolt 9 to prevent the smoke baffle cloth 4 from fluttering.

[0023] Among them, the inverted T shape of the counterweight strip 5 lowers the center of gravity, effectively enhancing the stability of the smoke baffle cloth 4 under the influence of wind pressure or other external forces.

[0024] Among them, the inverted T-shaped counterweight strip 5 is convenient for installation and disassembly, improving the convenience of use.

[0025] Further, the ceiling base plate includes a magnesium oxychloride board 7 and a gypsum board 8, and the gypsum board 8 is arranged below the magnesium oxychloride board 7.

[0026] Further, anti-collision sticker strips 6 are respectively installed above both ends of the counterweight strip 5.

[0027] Among them, adding anti-collision sticker strips 6 at the closing part of the counterweight strip 5 and the ceiling substrate ensures that the bottom plate and the ceiling finish surface are flat and beautiful after the smoke baffle 4 is raised.

[0028] Among them, the ceiling substrate adopts a combination of a magnesium oxychloride board 7 and a gypsum board 8 to prevent damage caused by the collision between the counterweight strip 5 and the ceiling substrate when the counterweight strip 5 rises too fast.

[0029] The beneficial effects of the present utility model:

[0030] By adding an inverted T-shaped counterweight strip 5 at the lower end of the smoke baffle cloth 4, the present utility model enhances the overall wind resistance of the present utility model by lowering the center of gravity, preventing the smoke baffle cloth 4 from fluttering around under the action of external forces and causing damage to other devices. Secondly, the inverted T-shaped design and the adoption of the anti-collision sticker strip 6 result in a horizontal line at the closing part of the smoke baffle cloth 4 and the ceiling substrate after the smoke baffle cloth 4 is raised, making the ceiling finish surface flat and beautiful.
