[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0028] As shown in the figure, a novel smoke baffle vertical wall for buildings comprises:

[0029] Two mounting brackets are mounted on the top of the building, and a mounting slot is formed between the two mounting brackets. Specifically, the two mounting brackets are a first mounting bracket 1 and a second mounting bracket 2, which can both be made of angle iron. On the one hand, they are used to be fixed on the top of the building, such as the bottom of the ceiling, the bottom of the beam or below the suspended ceiling. On the other hand, they are mainly used to connect the fixed vertical wall 3.

[0030] A reinforcing plate 4 is installed on one end of the mounting bracket and extends downward in the vertical direction on the other end. In this example, the number of reinforcing plates 4 is multiple, and the multiple reinforcing plates 4 are arranged at equal intervals along the length direction of the mounting bracket.

[0031] A lower frame body 5 is connected to the lower end of the reinforcing plate 4, and the length direction is parallel to the length direction of the mounting bracket. The reinforcing plate 4 can connect the upper mounting bracket and the lower frame body 5 below, so that the whole forms a more stable frame structure. In addition, the lower frame body 5 can also provide support effect for the fixed vertical wall 3, so that the fixed vertical wall 3 can be supported during installation, saving labor.

[0032] The fixed vertical wall 3 is made of non-combustible inorganic composite board or metal plate, which is arranged between the mounting bracket and the lower frame body 5, and the upper end is located in the mounting slot. Since the upper end of the fixed vertical wall 3 is placed inside the mounting slot and the lower end is supported by the lower frame body 5, the fixed vertical wall 3 can be prevented from falling during installation. In addition, the fixed vertical wall 3 can move along the length direction of the mounting slot, which can facilitate the movement of the fixed vertical wall 3 to the specified position, which is convenient and fast.

[0033] The movable vertical wall 8 is installed below the lower frame body 5 and can be lifted. The material of the movable vertical wall 8 is inorganic fiber fabric.

[0034] The lower edge of one of the mounting frames is provided with a clearance slot 201, the length of the clearance slot 201 is greater than the width of the fixed vertical wall 3. Specifically, the clearance slot 201 is located on the second mounting frame 2, and the number of clearance slots 201 can be set according to the actual situation. In this embodiment, the fixed vertical wall 3 adopts a modular design, and each fixed vertical wall 3 can enter the mounting slot from the position of the clearance slot 201. After the fixed vertical wall 3 enters the mounting slot, the fixed vertical wall 3 can be moved to the designated position.

[0035] The number of fixed vertical walls 3 in the mounting slot is multiple, and a sealing element 10 is arranged between two adjacent fixed vertical walls 3. The sealing element 10 is a rubber strip or a silica gel strip, which is mainly used to seal the gap between the two fixed vertical walls 3, improve the sealing effect, and avoid smoke leakage.

[0036] The upper end of the fixed vertical wall 3 is connected to the two mounting frames by bolt connection, the lower end of the fixed vertical wall 3 is connected to the lower frame body 5 by bolt connection, and the fixed vertical wall 3 is connected to the reinforcing plate 4 by bolt connection. Therefore, the fixed vertical wall 3 not only connects to the upper mounting frame, but also connects to the reinforcing plate 4 and the lower frame body 5, thereby improving the structural stability of the installation and improving the safety.

[0037] The lower end of the lower frame body 5 is fixed with a transmission box body 6, the inside of the transmission box body 6 has a rotatable transmission shaft 7, the movable vertical wall 8 is wound on the transmission shaft 7, and one end of the movable vertical wall 8 extends downward through the transmission box body 6. A bottom plate 9 is connected to the lower end of the movable vertical wall 8. More specifically, a transmission motor is also provided in the transmission box body 6, the transmission motor is connected to the transmission shaft 7, and is used to drive the transmission shaft 7 to rotate, so as to wind or unfold the movable vertical wall 8. In addition, a controller is installed on the side wall of the building, which is used to receive the alarm signal from the fire detector, issue an audible and light indication signal, and control the movable vertical wall 8 to descend to the smoke blocking working position. The controller should also be able to receive control signals from the fire linkage control device, issue signals to control the movable vertical wall 8 to complete the corresponding action within a specified time, and issue audible and light indication signals. The control structure and control principle belong to the conventional setting in the prior art, and will not be described in detail here.

[0038] The new smoke blocking vertical wall for buildings adopts the combination of fixed vertical wall 3 and movable vertical wall 8, which can meet the design requirements of existing buildings for smoke blocking height, and is not limited to the traditional smoke blocking height (500mm), and has better use effect. When there is no fire, the movable vertical wall 8 is in the storage state and does not affect the passage of people below. When a fire occurs, the movable vertical wall 8 is unfolded under the command of the control system, and cooperates with the fixed vertical wall 3 to improve the range of smoke blocking, and ensures the effectiveness and safety of the entire smoke blocking vertical wall in the fire. In addition, if the building is equipped with a smoke control system, the smoke blocking vertical wall can be connected to the smoke control system, and the smoke blocking vertical wall can be controlled by the smoke control system. Figure 5As shown, when the building has a pipe above, since the fixed vertical wall 3 is of a modular design (i.e. the fixed vertical wall 3 is assembled by multiple groups), two fixed vertical walls 3 close to the pipe can be cut according to the shape of the pipe, so that the problem of installing the smoke-proof vertical wall at the pipe position can be quickly solved.

[0039] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
