A fireproof perlite board

Abstract

This application discloses a fireproof perlite board, relating to the field of board technology. It includes a fixing frame and a locking assembly. The locking assembly provides a quick-connect structure. Multiple fixing frames can be spliced ​​together externally via the sliding insertion of a connecting rod into a limiting groove. An L-shaped support plate is then installed on top of the fixing frame using fixing screws, allowing two sets of connecting rods to be inserted into the two fixing frames for quick fixing. A pull ring drives a control rod to move, causing the limiting plate to pass through a slot into the top of the support frame. Rotating the control rod causes the limiting plate to rotate and misalign with the slot in the support frame, achieving support. A moving plate moves along the slot in the support frame under the action of a limiting sleeve rod. A guide rod moves within the slot in the support frame, causing a spring to deform under the pressure of the support frame and the moving plate, completing the locking process. This controls the insertion of the connecting rod into the fixing frame, facilitating use. The multi-layered structure of perlite board layer, crack-resistant board layer, flame-retardant board layer, waterproof board layer, and outer protective board layer enhances the overall performance.

Technical Field

[0001] This utility model relates to the field of sheet material technology, and in particular to a fireproof perlite sheet. Background Technology

[0002] Fireproof perlite insulation board, also known as FSG waterproof perlite insulation board, is a heat-insulating and waterproof insulation board made by using expanded perlite bulk as aggregate, adding waterproofing agent and binder, and then going through processes such as preparation, screening, pressure molding, and drying.

[0003] However, current fireproof perlite boards have a relatively simple structure, poor functionality, and are not easy to install.

[0004] Therefore, we provide a fireproof perlite board to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fireproof perlite board to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fireproof perlite board, comprising a fixing frame and a locking assembly. The locking assembly is installed on the outer side of the fixing frame. The locking assembly includes a plug-in rod fixedly connected to one side of the fixing frame. A limit groove is formed on the other side of the fixing frame. A fixing screw is threaded to the top of the fixing frame. An L-shaped support plate is rotatably connected to the outer side of the fixing screw through a slot. A support frame is fixedly connected to the top of the L-shaped support plate. A movable plate is slidably connected to the inner side of the support frame through a slot. A connecting rod is fixedly connected to the bottom end of the movable plate. The connecting rod and the fixing frame form a plug-in structure through a slot.

[0007] Preferably, the plug rods are provided in two sets distributed at right angles on one side of the fixing frame, and the limiting grooves are provided in two sets distributed at right angles on the other side of the fixing frame, and the size of the plug rods and the size of the limiting grooves are completely matched.

[0008] Preferably, a limiting sleeve is fixedly connected to the top center of the movable plate, and a control rod is rotatably connected to the inner side of the limiting sleeve through a slot.

[0009] Preferably, a pull ring is fixedly connected to the top end of the control rod, and a limit plate is fixedly connected to the surface of the control rod.

[0010] Preferably, guide rods are fixedly connected to both sides of the top of the movable plate, and the guide rods and the support frame form a sliding structure through slots, with springs sleeved on the outer side of the guide rods.

[0011] Preferably, a perlite board layer is fixedly connected to the inner side of the fixing frame, a crack-resistant board layer is bonded to the top of the perlite board layer, a flame-retardant board layer is bonded to the top of the crack-resistant board layer, a waterproof board layer is bonded to the top of the flame-retardant board layer, and an outer protective board layer is bonded to the top of the waterproof board layer.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The structure provides quick connection through locking components. Multiple sets of fixing frames can be spliced ​​on the outside by sliding the insertion rod and the limiting groove. Then, the L-shaped support plate is installed on the top of the fixing frame by fixing screws, so that the two sets of connecting rods are inserted into the two sets of fixing frames respectively, achieving quick fixation. The control rod is moved by the pull ring, so that the limiting plate passes through the slot to the top of the support frame. After the control rod is rotated, the limiting plate rotates and is misaligned with the slot of the support frame to achieve support. At the same time, the moving plate moves along the slot of the support frame under the action of the limiting sleeve rod. The guide rod moves in the slot of the support frame, so that the spring is deformed by the pressure of the support frame and the moving plate to complete the locking, thereby controlling the insertion of the connecting rod and the fixing frame, which is convenient to use.

[0014] 2. The overall performance of the device is enhanced through a multi-layered structure. The perlite board layer serves as the core fireproof and heat-insulating layer. Utilizing the porous structure of perlite, it provides fire resistance and heat insulation while also offering fundamental support, creating a stable base for the outer materials. It is also lightweight and fire-resistant. The crack-resistant board layer uses fiberglass or basalt fiber mesh, fixed to the perlite board surface with plaster mortar, enhancing overall crack resistance and preventing cracking due to temperature changes or external forces, thus improving structural durability. The flame-retardant board layer uses magnesium oxide flame-retardant board, rock wool flame-retardant board, or gypsum-based flame-retardant board to further enhance fire resistance. The fire-resistant material slows the spread of fire and can also serve as a leveling layer, providing a smooth base for the outer layer construction. The waterproof membrane layer uses self-adhesive waterproof membrane, fully adhered to the surface of the flame-retardant board, blocking the path of water penetration and preventing the perlite board from absorbing water and reducing its heat insulation performance. It also protects the internal structure from moisture erosion. The outer protective layer is a mortar injection layer with embedded fiber mesh to enhance crack resistance. It is coated with acrylic weather-resistant paint and uses polymer-modified mortar containing polypropylene fibers to reduce the risk of surface cracking. Silicone acrylic resin or fluorocarbon coating is selected, which has the characteristics of UV resistance, acid rain resistance, and pollution resistance. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 As shown, a fireproof perlite board includes a fixing frame 1 and a locking assembly 2. The locking assembly 2 is installed on the outer side of the fixing frame 1. The locking assembly 2 includes a plug rod 201 fixedly connected to one side of the fixing frame 1. A limit groove 202 is opened on the other side of the fixing frame 1. A fixing screw 203 is threadedly connected to the top of the fixing frame 1. An L-shaped support plate 204 is rotatably connected to the outer side of the fixing screw 203 through a slot. A support frame 205 is fixedly connected to the top of the L-shaped support plate 204. A movable plate 206 is slidably connected to the inner side of 205 via a slot. A connecting rod 207 is fixedly connected to the bottom end of the movable plate 206. The connecting rod 207 and the fixed frame 1 form an insertion structure through the slot. By sliding the insertion rod 201 into the limiting groove 202, multiple sets of fixed frames 1 can be spliced ​​on the outside. Then, the L-shaped support plate 204 is installed on the top of the fixed frame 1 by the fixing screw 203, so that the two sets of connecting rods 207 are respectively inserted into the two sets of fixed frames 1 to achieve quick fixation.

[0023] Furthermore, the plug-in rod 201 has two sets distributed at right angles on one side of the fixed frame 1, and the limiting groove 202 has two sets distributed at right angles on the other side of the fixed frame 1. The size of the plug-in rod 201 and the size of the limiting groove 202 are completely matched. Through the sliding plug-in of the plug-in rod 201 and the limiting groove 202, the outer side splicing of multiple sets of fixed frames 1 can be realized.

[0024] Furthermore, a limiting sleeve rod 208 is fixedly connected to the top center of the movable plate 206. A control rod 209 is rotatably connected to the inner side of the limiting sleeve rod 208 through a slot. The control rod 209 forms a rotating structure with the movable plate 206 through the limiting sleeve rod 208 and can drive displacement.

[0025] Furthermore, a pull ring 210 is fixedly connected to the top of the control rod 209, and a limit plate 211 is fixedly connected to the surface of the control rod 209. The pull ring 210 facilitates the movement of the control rod 209, and the limit plate 211 achieves a locking and limiting structure by rotating and misaligning after passing through the support frame 205.

[0026] Furthermore, guide rods 212 are fixedly connected to both sides of the top of the movable plate 206. The guide rods 212 and the support frame 205 form a sliding structure through the slots. A spring 213 is sleeved on the outside of the guide rods 212. The guide rods 212 move in the slots of the support frame 205, causing the spring 213 to deform under the pressure of the support frame 205 and the movable plate 206. After the lock is released, the spring 213 rebounds, causing the movable plate 206 to control the connecting rod 207 to be inserted into the fixed frame 1.

[0027] Furthermore, a perlite board layer 3 is fixedly connected to the inner side of the fixing frame 1. A crack-resistant board layer 4 is bonded to the top of the perlite board layer 3. A flame-retardant board layer 5 is bonded to the top of the crack-resistant board layer 4. A waterproof board layer 6 is bonded to the top of the flame-retardant board layer 5. An outer protective board layer 7 is bonded to the top of the waterproof board layer 6. The overall performance of the device is enhanced through a multi-layer structure. The perlite board layer 3 is the core fireproof and heat-insulating layer, utilizing the porous structure of perlite to provide fire resistance and heat insulation, while also providing basic support and a stable base for the outer materials. It also has lightweight and fire-resistant properties. The crack-resistant board layer 4 uses glass fiber or basalt fiber mesh cloth, which is fixed to the surface of the perlite board with plastering mortar to enhance the overall crack resistance and prevent the perlite board from cracking due to temperature. To prevent cracking due to temperature changes or external forces, and to improve structural durability, the flame-retardant board layer 5 uses glass magnesium flame-retardant board, rock wool flame-retardant board, or gypsum-based flame-retardant board to further enhance fire resistance and slow the spread of fire. It can also serve as a leveling layer, providing a flat base for the outer layer construction. The waterproof board layer 6 uses self-adhesive waterproof membrane, fully adhered to the surface of the flame-retardant board, blocking the path of water penetration and preventing the perlite board from absorbing water and reducing its thermal insulation performance. It also protects the internal structure from moisture erosion. The outer protective board layer 7 is a mortar injection layer with embedded fiber mesh to enhance crack resistance. It is coated with acrylic weather-resistant paint and uses polymer-modified mortar containing polypropylene fibers to reduce the risk of surface cracking. Silicone acrylic resin or fluorocarbon coating is selected, which has the characteristics of UV resistance, acid rain resistance, and pollution resistance.

[0028] Working principle: In use, firstly, by sliding the insertion rod 201 into the limiting groove 202, multiple sets of fixing frames 1 can be spliced ​​on the outside. Secondly, by fixing the screw 203, the L-shaped support plate 204 is installed on the top of the fixing frame 1, so that the two sets of connecting rods 207 are respectively inserted into the two sets of fixing frames 1 to achieve quick fixation. Thirdly, by pulling the ring 210 to drive the control rod 209 to move, the limiting plate 211 passes through the slot into the top of the support frame 205, and then the control rod 209 is rotated, driving the limiting plate 211 to move. 11. Following the rotation, the support frame 205 is misaligned with the slot, achieving support. Simultaneously, the moving plate 206 moves along the slot of the support frame 205 under the action of the limiting sleeve rod 208. The guide rod 212 moves within the slot of the support frame 205, causing the spring 213 to deform under the pressure of the support frame 205 and the moving plate 206, thus locking it in place. This controls the connection between the connecting rod 207 and the fixed frame 1 for easy use. Fourthly, the overall performance of the device is enhanced through a multi-layer structure. The perlite board layer 3 serves as the core fireproof and heat-insulating layer, utilizing the porous structure of perlite to resist fire. The perlite board layer 4 provides insulation and basic support, creating a stable base for the outer materials. It is lightweight and fire-resistant. The crack-resistant layer 4 uses fiberglass or basalt fiber mesh, fixed to the perlite board surface with plaster mortar to enhance overall crack resistance and prevent cracking due to temperature changes or external forces, thus improving structural durability. The flame-retardant layer 5 uses magnesium oxide flame-retardant board, rock wool flame-retardant board, or gypsum-based flame-retardant board to further enhance fire resistance, slow the spread of fire, and also serves as a leveling layer, providing a smooth base for the outer layer construction. On the surface, the waterproof layer 6 uses a self-adhesive waterproof membrane, which is fully adhered to the surface of the flame-retardant board to block the water penetration path and prevent the perlite board from absorbing water and reducing its heat insulation performance. At the same time, it protects the internal structure from moisture erosion. The outer protective layer 7 is a mortar injection layer with embedded fiber mesh cloth to enhance crack resistance. It is coated with acrylic weather-resistant paint and uses polymer-modified mortar containing polypropylene fibers to reduce the risk of surface cracking. Silicone acrylic resin or fluorocarbon coating is selected, which has the characteristics of UV resistance, acid rain resistance, and pollution resistance. This completes the use of a fireproof perlite board.
