Description

Technical Field

[0001] The utility model relates to the technical field of building facilities, in particular to a smoke barrier vertical wall with a low installation height. Background Art

[0002] Smoke barriers are made of non-combustible materials and are installed vertically under building ceilings, beams, or suspended ceilings to create a smoke-retention zone in the event of a fire. They are primarily used in high-rise or super-high-rise shopping malls, office buildings, warehouses, and other places, playing a role in protecting people's lives and property.

[0003] At present, some smoke barriers on the market generally adopt a design method of being fixedly installed below the top of the building, which inevitably occupies a certain amount of space on the top of the building, bringing certain restrictions to space utilization and architectural design. In addition, some smoke barriers adopt a roller shutter installation method. Although this method can save space when stored, its unloading speed is relatively slow, resulting in the smoke barrier being released not quickly enough in an emergency, which may affect its proper smoke-proof effect. Moreover, the structure of the roller shutter type smoke barrier is relatively complex, which increases the possibility of failure, and may cause the smoke barrier to fail to be released in time, thereby increasing safety risks. There are also some flap-type smoke barriers, which are not convenient for adjusting the drop height according to the structure of the building and the installation height of the smoke barrier. Therefore, the utility model provides a smoke barrier with a low installation height to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0024] Reference Figure 1-4 The embodiment of the utility model is a low-mounting height smoke barrier wall, which includes a mounting plate 1, one side of the bottom of the mounting plate 1 is hinged with a first smoke barrier wall 2, and the top of the mounting plate 1 and one side near the hinge are slidably connected with a positioning plate 4 with a U-shaped structure, the bottom of the positioning plate 4 can be slidably connected with the bottom of the first smoke barrier wall 2, and the side of the positioning plate 4 near the second smoke barrier wall 3 is installed with a roller 11, when the bottom of the positioning plate 4 pushes the first smoke barrier wall 2 to flip, the roller 11 cooperates with the first smoke barrier wall 2 to contact and slide, making the movement smoother. A cylinder 5 is fixedly connected to the top of the mounting plate 1 and one side near the positioning plate 4, and the piston rod of the cylinder 5 is fixedly connected to the positioning plate 4. Two fixed plates 6 are symmetrically fixedly connected to the top of the mounting plate 1 and on both sides of the cylinder 5, and the inside of the fixed plate 6 is slidably connected with a guide rod 7 fixedly connected to the positioning plate 4. When the positioning plate 4 moves, it drives the guide rod 7 to slide inside the fixed plate 6, playing a supporting role for the positioning plate 4, which is beneficial to ensuring the stability of the movement of the positioning plate 4.

[0025] Under normal conditions, the first smoke barrier 2 is attached to the bottom of the mounting plate 1 under the support of the positioning plate 4. The horizontally arranged first smoke barrier 2 can effectively reduce the space occupied at the top of the building. In the event of a fire, the cylinder 5 operates to push the positioning plate 4 to the side away from the first smoke barrier 2. After the positioning plate 4 separates from the first smoke barrier 2, the first smoke barrier 2 is free to flip and fall under the action of gravity, playing a blocking role to effectively block the lateral flow of smoke. The simple structure realizes the rapid release of the smoke barrier, reduces the possibility of mechanical failure, ensures the reliability of the smoke barrier in emergency situations, and provides an important guarantee for the safety protection of the building.

[0026] The bottom of the first smoke barrier 2 is slidably connected to the second smoke barrier 3. A sealing gasket 12 is also provided on the side where the second smoke barrier 3 is in contact with the first smoke barrier 2. The design of the sealing gasket 12 ensures a good seal between the two, thereby enhancing the smoke-proof effect. The first smoke barrier 2 and the second smoke barrier 3 are movably connected via two symmetrically arranged connecting components. The connecting component includes a guide rail 9 fixedly connected to one side of the first smoke barrier 2 and provided with a U-shaped structure, a connecting plate 10 slidably connected to the inner side of the guide rail 9, a screw 13 fixedly connected to one side of the connecting plate 10, and a nut 14 provided on one side of the guide rail 9 and connected to the screw 13. The connecting plate 10 is fixedly connected to the second smoke barrier 3. The screw 13 extends through the guide rail 9 to the outside of the guide rail 9, and a sliding groove for the screw 13 is provided on the side of the guide rail 9 away from the first smoke barrier 2.

[0027] During normal use, the first smoke barrier 2 and the second smoke barrier 3 play a good smoke barrier role. When the lowering height of the second smoke barrier 3 needs to be adjusted according to the installation height of the mounting plate 1, the extension length of the second smoke barrier 3 can be freely moved by loosening the nut 14 and separating it from the outer side of the guide rail 9. After the moving second smoke barrier 3 drives the screw 13 to move to the corresponding position inside the slide groove, the positioning of the second smoke barrier 3 can be completed by tightening the nut 14. The adjustment operation is simple, which is conducive to adjusting the lowering height of the second smoke barrier 3 according to actual use needs and is flexible in use.

[0028] To facilitate the connection between the mounting plate 1 and the mounting surface, two L-shaped mounting seats 8 are symmetrically fixedly connected to the top of the mounting plate 1. The positioning plate 4 is slidably connected to the inside of the adjacent mounting seat 8 to ensure the smooth movement of the positioning plate 4. The other mounting seat 8 maintains a closed structure to block the connection between the mounting plate 1 and the mounting surface.

[0029] The first smoke barrier wall 2 and the second smoke barrier wall 3 are made of rigid materials. The first smoke barrier wall 2 and the second smoke barrier wall 3 can be made of commonly used impermeable materials, such as metal plates, non-combustible inorganic composite panels, fire-proof glass and other rigid materials to ensure the stability of the first smoke barrier wall 2 and the second smoke barrier wall 3 when they are in a horizontal state.

[0030] Working principle: Under normal conditions, the first smoke barrier 2 is attached to the bottom of the mounting plate 1 under the support of the positioning plate 4. The horizontally arranged first smoke barrier 2 can effectively reduce the occupied top space of the building. In the event of a fire, the cylinder 5 operates to push the positioning plate 4 to move to the side away from the first smoke barrier 2. After the positioning plate 4 is separated from the first smoke barrier 2, the first smoke barrier 2 is free to flip and fall under the action of gravity, playing a blocking role to effectively block the lateral flow of smoke. The structure is simple, and the rapid release of the smoke barrier is achieved, which reduces the possibility of mechanical failure, ensures the reliability of the smoke barrier in emergency situations, and provides an important guarantee for the safety protection of the building.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
