Detailed Description
As shown in fig. 1 and fig. 2, the building decorative panel comprises a decorative panel 3 installed on a concrete wall 1, a hollow cavity 7 is formed in a position, close to an indoor side, of the concrete wall, an installation wall 4 is formed on the concrete wall through the hollow cavity 7, the decorative panel 3 is installed on the surface of the installation wall 4 in an up-and-down sliding mode, an opening cavity 11 is formed in the top of the installation wall 4, the decorative panel 3 penetrates through the opening cavity 11 to enter the hollow cavity 7, an air bag interlayer 2 is filled in the hollow cavity 7, the air bag interlayer 2 extends towards the top of the concrete wall 1, a balancing weight 5 is placed at the topmost part of the air bag interlayer 2, the decorative panels 3 are vertically stacked and are all connected through an elastic belt 6, and the elastic belt of the topmost decorative panel 3 is connected with the balancing weight 5.
As shown in fig. 5, more than one first magnet 31 is embedded in the upper and lower end faces of each decorative plate 3, the stacked decorative plates 3 are attracted in an opposite attraction manner by the first magnets 31, the ceiling is embedded with the second magnets 9, the first magnets 31 on the topmost decorative plate 3 are attracted in an opposite attraction manner after being contacted with the second magnets 9, more than one longitudinal guide rail (not shown) is embedded in the installation wall 4 relative to one side face of the decorative plate 3, longitudinal guide rail grooves are formed in the longitudinal guide rails, slide blocks 33 are arranged on the decorative plates right opposite to the longitudinal guide rail grooves, and the slide blocks 33 are slidably installed in the guide rail grooves. Fix a position about realizing through magnet, prevent 3 displacements of decorative board, general decorative board 3 is not the bearing, and decorative board 3 at topmost also can not receive the striking, so utilize the magnet piece location can. And the decorative board of intermediate position is packed into in the direction spout through the slider and is accomplished the location, prevents the removal of left and right sides direction, has also prevented the separation of decorative board and longitudinal guide groove, fine completion location, and after gasbag interlayer 2 damaged, each decorative board is through the upward motion of longitudinal guide.
The slide block 33 and the longitudinal guide rail groove are in a T-shaped shape, and the T-shaped structure aims to prevent the slide block from being separated from the longitudinal guide rail groove and achieve the purpose of limiting.
As shown in fig. 5, a through hole 34 is formed in the middle of the decorative plate 3, a filling protrusion 21 is disposed on the airbag partition 2 opposite to the through hole 34, and when the airbag partition 2 is filled with gas, the filling protrusion 21 protrudes and fills the through hole 34.
When a fire disaster occurs, the flame can contact the decorative plate, but the surface of the decorative plate can be subjected to certain fireproof treatment, so that the flame can firstly damage the filling convex part which is not subjected to the fireproof treatment, after the filling convex part is damaged, the volume of the whole air bag interlayer is reduced, the balancing weight is not supported any more, and the balancing weight descends under the action of gravity, so that the topmost decorative plate is pulled by the elastic belt, and as the upper surface and the lower surface of the topmost decorative plate are only provided with the magnet block for attracting and positioning, the weight of the balancing weight cannot be borne, and then the balancing weight is hoisted into the hollow cavity, as shown in figures 3 and 4, after the topmost decorative plate is pulled into the hollow cavity, the rest decorative plates can be pulled into the position of the open cavity under the pulling force, the pulling length of the elastic belt cannot be too long, otherwise, the pulling cannot be realized under the condition that the height is not enough, so that the pulling, therefore, the elastic belt is used for overcoming the bending of the opening cavity, and the elastic belt can not be stretched after being stretched to a point, and is the same as a common pulling rope, so that the pulling base of a decorative board is realized.
Wherein, the shrinkage pool 32 has all been seted up to the upper and lower face of decorative board, and the one end of elastic webbing 6 is all fixed to be packed into in shrinkage pool 32 for connect adjacent decorative board 3, the quality of balancing weight 5 is greater than the total mass of every row of decorative board 3, and every row of decorative board 3 corresponds balancing weight 5, and when the decorative board was located each decorative board topmost, the slider was from the separation of longitudinal guide rail inslot. The mass of balancing weight should be enough big, just so have the decorative board tractive that will arrange with and enter into the fretwork intracavity. And when the decorative board was located the top position, slider and slide rail separation this moment can realize bending to the decorative board, and then can drag into the fretwork intracavity.
In this embodiment, the inside gas of filling of gasbag interlayer 2 is inert gas, fill convex part 21 on gasbag interlayer 2 by the damaged back, inside inert gas runs out fast, under the extrusion force of balancing weight, inert gas's exhaust velocity is faster, the inert gas who runs out can dilute peripheral oxygen content fast, reduce the intensity of a fire size, prevent that flame is too much and decorative board contact, if the fire source is not big, can also play the purpose of automatic fire extinguishing, so the gasbag interlayer not only has the thermal-insulated function of keeping warm, still has the function of putting out a fire, and be used for supporting the function of balancing weight.
The invention has the beneficial effects that: the invention realizes heat preservation and heat insulation by utilizing the air bag interlayer, and extinguishes surrounding flames by utilizing inert gas in the air bag interlayer; and after the gasbag interlayer is damaged, the decorative board pull that will correspond automatically enters into the fretwork chamber, and then keeps apart the decorative board, prevents flame and decorative board contact, reduces the speed that indoor intensity of a fire stretchs, promotes the security.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
