Description

Technical Field

[0001] This utility model relates to the technical field of building construction, and in particular to a smoke curtain installation device. Background Technology

[0002] In the field of modern building construction, smoke curtains are key fire protection facilities that can create a certain smoke storage space during a fire. Smoke curtains can effectively block the lateral spread of smoke, buying valuable time for personnel evacuation and fire rescue.

[0003] Existing fixed smoke curtain installation methods mainly involve vertically installing them under building ceilings, beams, or suspended ceilings. Utility model patent CN222238597U discloses an installation structure for a smoke curtain, including a wall body. Hangers are installed on both sides of the lower part of the wall body, and a suspended ceiling is installed below the hangers. A support frame is installed below the wall body, with a first bolt passing through the top of the support frame, a second bolt passing through one side of the lower part of the support frame, and a fixing plate installed below the support frame. Third bolts pass through both sides of the fixing plate.

[0004] However, such devices still have their limitations. Because they are mainly fixed with multiple bolts, if the smoke curtain is damaged after a fire (such as the fireproof glass of the smoke curtain breaking), multiple bolts of the entire device need to be removed before the smoke curtain can be replaced, which is inconvenient to disassemble and assemble.

The device is characterized by including a first connecting structure for connecting the smoke curtain to the indoor floor slab. The first connecting structure includes a first connecting part and a second connecting part. The first connecting part is connected to the indoor floor slab, and the second connecting part is connected to the smoke curtain. The first connecting part has a cavity inside and an opening communicating with the cavity. The second connecting part includes a connector that passes through the opening and is connected to the cavity. The connector includes a limiting part that abuts against the cavity wall to prevent the connector from leaving the opening.

[0007] Furthermore, the smoke curtain installation device provided by this utility model may also have the following feature: the end of the limiting part forms a guide arc plate for guiding the connector through the opening.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This utility model provides a smoke curtain installation device, the specific structure of which is as follows:

[0025] The smoke curtain installation device is used to install the fixed smoke curtain 7 onto the indoor floor slab 11, such as... Figure 1 and Figure 2As shown, the smoke curtain installation device includes a first connecting structure for connecting the smoke curtain 7 and the indoor floor slab 11. The first connecting structure includes a first connecting part 2 and a second connecting part 3. The first connecting part 2 is connected to the indoor floor slab 11, and the second connecting part 3 is connected to the smoke curtain 7. The first connecting part 2 has a cavity 24 inside and an opening 25 on it, which communicates with the cavity 24. The second connecting part 3 includes a connector 31 that passes through the opening 25 and is connected to the cavity 24. The connector 31 includes a limiting part 32 that abuts against the cavity wall of the cavity 24 to prevent the connector 31 from leaving the opening 25. In a specific embodiment, the connector 31 is preferably an n-shaped stainless steel plate. During connection, the n-shaped stainless steel plate includes two vertical plates. The vertical plate located inside the cavity 24 and abutting against the cavity wall of the cavity 24 forms the aforementioned limiting part 32. In use, the smoke curtain 7 can be assembled and disassembled by inserting or removing the irregularly shaped connector 31 from the opening 25 into or out of the cavity 24. Furthermore, due to the presence of the limiting part 32 that abuts against the cavity wall of the cavity 24, the connector 31 will not leave the opening 25 when the smoke curtain 7 is fixed, ensuring the stability of the smoke curtain 7 installation.

[0026] Furthermore, the end of the limiting part 32 is formed with a guide arc plate 33 for guiding the connector 31 through the opening 25; when the connector 31 passes through the opening 25 and is connected to the cavity 24, the center of the guide arc plate 33 is located inside the cavity 24.

[0027] like Figure 1 As shown, the first connecting part 2 is detachably connected to the indoor floor slab 11. Specifically, the first connecting part 2 includes a first bracket 21 with the aforementioned opening 25; the first connecting part 2 also includes two second brackets 22 connected to the indoor floor slab 11, with the two second brackets 22 respectively located on both sides of the first bracket 21 and connected to it to ensure the stability of the entire first connecting part 2. Preferably, the first bracket 21 is a vertical plate formed of galvanized angle steel, and the second bracket 22 is a horizontal bar formed of galvanized angle steel; the second brackets 22 are detachably connected to the indoor floor slab 11 by expansion bolts 23 for easy replacement and maintenance; the first bracket 21 and the second bracket 22 can be connected by welding or bolts.

[0028] like Figure 1 As shown, the second connecting part 3 is also detachably connected to the smoke curtain 7. Specifically, the second connecting part 3 is connected to the smoke curtain 7 via a second connecting structure, which includes a fastening nut 42, a first connecting hole on the second connecting part 3, a second connecting hole on the smoke curtain 7, and a fastening bolt 41 that passes through the first connecting hole and the second connecting hole in sequence and is connected to the fastening nut 42.
