Embodiment 1

[0043] In this example, if figure 1 As shown, the movable smoke-shielding vertical wall is made of a top plate 1, a bottom plate 2, a flexible smoke-shielding vertical wall 3 made of non-combustible materials, a rope 101, and a thermal fuse element (a cylindrical glass tube 4 with a heat-sensitive solution 5 inside is adopted) composition. Wherein the top plate 1 is used to fix the movable smoke-shielding vertical wall at a specific position inside the building; the upper part of the flexible smoke-shielding vertical wall 3 is connected with the top plate 1, and the lower part is connected with the bottom plate 2; small holes are left on both sides of the bottom plate 2 respectively. One ends of the two ropes 101 are respectively fixed on both sides of the top plate 1, and the other ends respectively pass through the small holes on the bottom plate 2, meet under the bottom plate 2, and are respectively fixed at the two ends of the glass tube 4. The diameter of the small hole ...

Embodiment 2

[0048] In this example, if Figure 5 and 6 As shown, the movable smoke-shielding vertical wall is composed of a top plate 1, a bottom plate 2, a flexible smoke-shielding vertical wall 3 made of non-combustible materials, a fixed rod 201 and a glass tube 4 with a heat-sensitive solution 5 inside. Wherein the top plate 1 is used to fix the movable smoke-shielding vertical wall at a specific position inside the building. The upper part of the flexible smoke-shielding vertical wall 3 is connected with the top plate 1, and the lower part is connected with the bottom plate 2; the bottom plate 2 has a small circular hole. The fixed rod 201 is a strip bar with a ring (the diameter of the ring is slightly smaller than the small hole on the bottom plate 2) at the bottom, its top is fixed on the top plate 1, and the bottom passes through the small hole of the bottom plate 2, and its ring is exposed. on the lower side of the bottom plate 2. A glass tube 4 with a heat-sensitive solution...

Embodiment 3

[0053] In this example, if Figure 8 and 9 As shown, the movable smoke-shielding vertical wall is composed of a top plate 1, a bottom plate 2, a flexible smoke-shielding vertical wall 3 made of non-combustible material, a glass tube 4 with a heat-sensitive solution 5 inside, a fixed rod 201 and a control box 203. The fixing rod 201 and the glass tube 4 of this embodiment restrict the bottom plate 2 in a similar manner to that of Embodiment 2, but there are differences in the rest, and the specific structure is as follows:

[0054]The top plate 1 is used to fix the movable smoke-shielding vertical wall at a specific position inside the building, and has two circular small holes on it. The upper part of the flexible smoke-shielding vertical wall 3 is connected with the top board 1 , and the lower part is connected with the bottom board 2 . Circular small holes are also left on the base plate 2 . Fixed rod 201 is a strip bar, and its bottom has a circular limit ring (the diame...

Abstract

The invention discloses a movable smoke-blocking ceiling screen and belongs to the field of fire-fighting facilities. The movable smoke-blocking ceiling screen comprises a top plate, a flexible smoke-blocking ceiling screen body, a base plate and a thermal fusing element. The two ends of the flexible smoke-blocking ceiling screen body are fixed to the top plate and the base plate correspondingly and extend and contract along with variation of the distance between the two plates. A limiting component is arranged between the top plate and the base plate and used for limiting the base plate from moving relative to the top plate with the distance increased. The limiting component comprises the thermal fusing element which is fused when being heated. The thermal fusing element is used for eliminating limitation of the limiting component on the base plate when being fused. By means of the movable smoke-blocking ceiling screen, thinning tendency can be achieved; and the problem that a fixed smoke-blocking ceiling screen or a movable smoke-blocking ceiling screen occupies the height below or inside a ceiling is thoroughly solved. The movable smoke-blocking ceiling screen can be as thin as 1-2 cm in thickness at a maximum; the thickness is smaller than that of the ceiling; and the movable smoke-blocking ceiling screen is simple in structure and low in production cost and maintenance cost.

Description

technical field [0001] The invention belongs to the field of fire-fighting facilities, and in particular relates to a movable smoke-retaining vertical wall and a method thereof. Background technique [0002] The smoke-blocking vertical wall is made of non-combustible materials, installed under the building ceiling, beams or ceiling, and can form a smoke-blocking separation facility with a certain smoke storage space in the event of a fire. Its main function is to block the lateral spread of smoke under the building roof, beams or ceiling during a fire, and confine it to a specific area so that the smoke can be discharged through the smoke exhaust facilities in the area in time. [0003] Smoke baffles are divided into fixed smoke baffles and movable smoke baffles. [0004] The fixed smoke-shielding vertical wall is generally not less than 500mm high and installed under the ceiling, beam or ceiling. Since the fixed smoke-blocking wall is a fixed structure and takes up a lot ...
