Description

Technical Field

[0001] The utility model relates to a smoke barrier vertical wall, in particular to a foldable electromagnetic smoke barrier vertical wall, and belongs to the technical field of fire fighting equipment. Background Art

[0002] There are generally two ways to install smoke barriers in the prior art: one is a fixed smoke barrier, which is directly installed on the corridor ceiling of the fire-proof partition; the other is an electric retractable or roller-type smoke barrier, which is hidden under normal circumstances and requires a cut on the ceiling to receive the smoke barrier motor and reel above the ceiling, and then controlled to descend through signal linkage when a fire alarm is triggered.

[0003] The defect of fixed smoke barrier walls is that they reduce the overall height of the corridor, causing visual depression, and are easily accidentally bumped, resulting in breakage. Specifically, based on comprehensive energy consumption considerations, the general corridor height is set between 2.4-2.8m. For a 2.6m high ceiling, the installation size of the smoke barrier wall is generally not less than 0.5m, resulting in a net height of less than 2.1m for the corridor smoke barrier wall, which can be easily reached by hand, leading to accidental bumping. Electric retractable or roller shutter smoke barrier walls have the problem of high cost, which is 3-4 times that of fixed ones. On the other hand, they also destroy the integrity of the ceiling and are not suitable for areas with purification control requirements. Utility Model Content

[0004] The utility model provides a foldable electromagnetic smoke barrier vertical wall, which aims to overcome the above-mentioned shortcomings of the prior art, avoid affecting the overall height of the corridor, avoid damaging the ceiling, and achieve a lower construction cost.

[0005] The technical solution of the utility model is: a foldable electromagnetic smoke barrier wall, the structure of which includes a fixed profile, a smoke barrier wall body, a magnetic suction piece and an electromagnet, wherein the smoke barrier wall body includes a vertical fixing part and a folding part, the vertical fixing part and the folding part are connected by a hinge, the top of the vertical fixing part is fixed to the ceiling by a fixed profile, a magnetic suction piece is provided near the outer edge of the folding part, an electromagnet is provided on the ceiling, and the position of the electromagnet corresponds to the position of the electromagnet on the folding part when the smoke barrier wall body is in a folded state. The above structure can be applied to personnel flow channels with clean control requirements and limited space, without destroying the ceiling, to ensure integrity and sealing.

[0006] Preferably, the vertical fixing portion and the folding portion are both made of fire-resistant glass.

[0007] Preferably, the outer edge of the folded portion is wrapped with a trimming profile to improve the structural strength.

[0008] Preferably, the magnetic attraction member is a metal magnetic attraction, which can ensure the magnetic attraction effect.

[0009] Preferably, the hinge is a stainless steel metal hinge, which can ensure connection strength and fire resistance.

[0010] The advantages of the utility model are as follows: the structural design is reasonable, compared with the fixed smoke barrier wall, it can effectively increase the visual space of the corridor and reduce the risk of accidental collision, compared with the electric retractable or roller shutter type smoke barrier wall, it can effectively reduce the cost, and there is no need to destroy the ceiling.

[0014] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0015] like Figure 1 , 2 As shown, a foldable electromagnetic smoke barrier wall has a structure including a fixed profile 2, a smoke barrier wall body, a magnetic suction piece 7 and an electromagnet 8, wherein the smoke barrier wall body includes a vertical fixed portion 3 and a folding portion 4, the vertical fixed portion 3 and the folding portion 4 are connected by a hinge 5, the top of the vertical fixed portion 3 is fixed to the ceiling 1 by a fixed profile 2, the outer edge of the folding portion 4 is wrapped with a trimming profile 6, a magnetic suction piece 7 is provided on the folding portion 4 near the outer edge, an electromagnet 8 is provided on the ceiling 1, the position of the electromagnet 8 corresponds to the position of the electromagnet 8 on the folding portion 4 when the smoke barrier wall body is in a folded state, the vertical fixed portion 3 and the folding portion 4 are both fire-resistant glass, the magnetic suction piece 7 is a metal magnet, and the hinge 5 is a stainless steel metal hinge.

[0016] According to the above structure, the installation of the smoke barrier wall body is consistent with the fixed smoke barrier wall; after the installation is completed, the electromagnet 8 on the ceiling 1 and the magnetic suction part 7 on the smoke barrier wall body are adsorbed to each other through the fire-fighting electricity (the number of adsorption points and the kilograms adsorbed can be specifically determined according to the weight of the folding part 4 and the length of the space); the electromagnet 8 can be linked with the fire-fighting system according to the control method of the existing technology. For example, when the smoke sensor 9 detects smoke, the fire-fighting system transmits a control signal to cut off the power supply of the electromagnet 8, so that the smoke barrier wall body is restored from the folded state to the vertical state. Example

[0017] The height of suspended ceiling 1 is 2.6m. When the smoke barrier wall is folded, the net height is not less than 2.4m.
