Description

Technical Field

[0001] The utility model relates to the technical field of sandwich exterior wall panels, in particular to an assembled rock wool polyurethane edge-sealed exterior wall panel. Background Art

[0002] Polyurethane edge-banding composite panels are mainly made of rock wool and glass wool. They use coated steel plates as the surface material, continuous cotton fiber rock wool and glass wool as the core material, and high-density rigid foamed polyurethane as the tongue and groove filling. They are composited after high-pressure foaming and curing, automatic dense cotton distribution, and controlled molding by ultra-long precision double crawlers.

[0003] For example, the authorization announcement number "CN216075706U" is named a rock wool polyurethane edge-sealed seamless exterior wall panel. A reinforcing mesh is arranged inside the metal panel, which can play a good role in supporting the metal panel, strengthening the strength of the sandwich panel, and improving the deformation resistance of the sandwich panel. However, the existing rock wool polyurethane edge-sealed seamless exterior wall panel adopts a docking assembly with connection ends that can be bitten and spliced on both sides of the panel body. However, the two adjacent rock wool polyurethane edge-sealed seamless exterior wall panels can only be fixed by the friction and biting force of the slots at the connection ends. The overall connection is not strong enough. When the rock wool polyurethane edge-sealed seamless exterior wall panel needs to be installed on the wall of the building, it is inevitable to perform nailing, installation, and fixing operations. In this way, gaps are easily generated between the rock wool polyurethane edge-sealed seamless exterior wall panels with insufficient connection, or the connection is not tight, thereby reducing the assembly firmness of the rock wool polyurethane edge-sealed seamless exterior wall panels.

[0004] At the same time, the existing rock wool polyurethane edge-sealed seamless exterior wall panels have multiple cross-reinforced meshes inside the panel body to enhance the structure's ability to resist deformation. However, the multiple cross-reinforced meshes can only provide the best vertical pressure support effect on the front of the rock wool polyurethane edge-sealed seamless exterior wall panels. When facing scratches and collisions from both sides, the cross-reinforced meshes are difficult to achieve the effect of improving the support effect. On the contrary, the cross-reinforced meshes are prone to dents and panel deflection when scratched from the side, which reduces the structural strength of the rock wool polyurethane edge-sealed seamless exterior wall panels. Utility Model Content

[0005] The utility model aims to solve the problems of poor assembly firmness and low structural strength of rock wool polyurethane edge-sealed seamless exterior wall panels, and proposes an assembled rock wool polyurethane edge-sealed exterior wall panel.

The bonding layer is arranged relatively parallel to the metal panel layer along the wall panel body. Exterior wall panel assembly connection structures are provided on both sides of the wall panel body, and an exterior wall panel internal reinforcement structure is provided inside the wall panel body.

[0010] Preferably, a polyurethane edge sealing layer is fixedly installed inside the first bite member, a polyurethane edge sealing layer is fixedly installed inside the second bite member, and the end of the first bite member is arranged opposite to the end of the second bite member.

[0012] Preferably, both ends of the plurality of first oblique rods are fixedly connected to the inner wall of the wall panel body, both ends of the plurality of second oblique rods are fixedly connected to the inner side of the wall panel body, and two second oblique rods are respectively connected to both sides of the first oblique rod.

[0013] The utility model proposes an assembled rock wool polyurethane edge-sealed exterior wall panel, which has the beneficial effect of: after the first bite part and the second bite part are respectively connected to the two sides of the assembly part, the fixing bolt is rotated and screwed into the connection seam of the first bite part and the second bite part, and the end of the fixing bolt is rotated and screwed into the interior of the assembly part, and the first bite part and the second bite part are fixed by utilizing the extrusion force of the clamping plate. The connection between the two assembled rock wool polyurethane edge-sealed exterior wall panels is fixed by the connecting parts, which is more firm and stable than the friction bite connection method, thereby improving the assembly firmness of the assembled rock wool polyurethane edge-sealed exterior wall panels.

[0014] Multiple diagonal rods are made of aluminum plate material, which is relatively light and can provide effective support. Multiple first diagonal rods run diagonally across the inside of the wall panel, which can improve the vertical support capacity of the wall panel body. In this way, multiple second diagonal rods can reinforce the two first diagonal rods to reduce the occurrence of compressive deformation, and are not easy to be dented and deformed due to external pressure and impact.

[0022] The present invention will be further described below with reference to the accompanying drawings: Example

[0023] See also Figure 1-6 : In this embodiment, an assembled rock wool polyurethane edge-sealed exterior wall panel includes a wall panel body 1, a bonding layer 2 and a metal panel layer 3. The metal panel layer 3 is fixedly installed on one side of the outer wall of the wall panel body 1, and the metal panel layer 3 is installed at the front end of the wall panel body 1. The metal panel layer 3 is made of color steel material, which has good wear resistance and waterproof performance, thereby improving the service life of the wall panel body 1. The bonding layer 2 is fixedly installed on the other side of the outer wall of the wall panel body 1. The bonding layer 2 is made of strong, sturdy and thickened aluminum alloy material. By arranging the bonding layer 2 on the rear side of the wall panel body 1, the wear resistance and durability of the wall installation can be improved. The bonding layer 2 is arranged relatively parallel to the metal panel layer 3 along the wall panel body 1. Exterior wall panel assembly connection structures 4 are provided on both sides of the wall panel body 1, and the interior of the wall panel body 1 is provided with an exterior wall panel internal reinforcement structure 6.

[0024] The exterior wall panel assembly connection structure 4 includes a first bite member 41 and a second bite member 42. The first bite member 41 is fixedly installed on one side of the outer wall of the wall panel body 1. The first bite member 41 is designed as a barb type, and the second bite member 42 is designed as an inverted barb type. When assembling two wall panel bodies 1, the first bite member 41 on one side of one wall panel body 1 is aligned with the second bite member 42 on the other side of the other wall panel body 1 and they are close to each other. The second bite member 42 is fixedly installed on the other side of the outer wall of the wall panel body 1, and an assembly part 43 is movably connected between the first bite member 41 and the second bite member 42.

[0025] The assembly part 43 is made of a vertical and hard aluminum alloy material. The size of the assembly part 43 matches the size of the connection hole between the first bite part 41 and the second bite part 42. A plurality of reinforcing cores 44 are fixedly installed inside the assembly part 43. The reinforcing cores 44 are made of a plurality of high-strength steel bars that vertically penetrate the interior of the assembly part 43. The reinforcing cores 44 are used to improve the deformation resistance of the assembly part 43. After the first bite part 41 and the second bite part 42 are respectively connected to the two sides of the assembly part 43, the fixing bolts 45 are screwed in. The fixing bolts 45 are screwed into the connection seam between the first and second bite parts 41 and 42, and the ends of the fixing bolts 45 are screwed into the interior of the assembly part 43. The fixing bolts 45 then drive the outer pressure plates 46 to fit tightly against the outer sides of the two adjacent metal panel layers 3 and the bonding layer 2. The first and second bite parts 41 and 42 are fixed to each other by the extrusion force of the pressure plates 46. A plurality of fixing bolts 45 are threadedly connected to both sides of the assembly part 43, and a pressure plate 46 is fixedly connected to the outer sides of the plurality of fixing bolts 45.

[0026] The first bite piece 41 is designed as a barb type, and the second bite piece 42 is designed as an opposite barb type. When assembling two wall panel bodies 1, the first bite piece 41 on one side of one wall panel body 1 is aligned with the second bite piece 42 on the other side of the other wall panel body 1 and they are close to each other. The assembly part 43 is made of vertical and hard aluminum alloy material. The size of the assembly part 43 is consistent with the size of the connecting hole between the first bite piece 41 and the second bite piece 42. The reinforcement core 44 is made of multiple high-strength steel bars that vertically penetrate the interior of the assembly part 43.

[0027] The deformation resistance of the assembly part 43 is improved by reinforcing the core 44. After the first bite part 41 and the second bite part 42 are respectively connected to the two sides of the assembly part 43, the fixing bolt 45 is rotated and screwed into the connection seam between the first bite part 41 and the second bite part 42. The end of the fixing bolt 45 is rotated and screwed into the interior of the assembly part 43. Then the fixing bolt 45 will drive the outer clamping plate 46 to fit tightly against the outer sides of the two adjacent metal panel layers 3 and the bonding layer 2. The extrusion force of the clamping plate 46 is used to fix the first bite part 41 and the second bite part 42. The connection between the two assembled rock wool polyurethane edge-sealed exterior wall panels is fixed by the connecting parts, which is more firm and stable than the friction bite connection method, thereby improving the assembly firmness of the assembled rock wool polyurethane edge-sealed exterior wall panels.

[0028] The inner sides of the two pressing plates 46 are movably connected to the outer wall of the metal panel layer 3, and the inner sides of the other ends of the two pressing plates 46 are movably connected to the outer wall of the bonding layer 2. One side of multiple fixing bolts 45 is movably connected to the end of the first bite part 41, and the other side of multiple fixing bolts 45 is movably connected to the end of the second bite part 42. The interior of the first bite part 41 is fixedly installed with a polyurethane edge sealing layer 5. The polyurethane edge sealing layer 5 adopts the existing technology disclosed in the comparative document publication number "CN216075706U" named a rock wool polyurethane edge sealing seamless exterior wall panel. The polyurethane sealing plate layer 5 is filled in the interior of the first bite part 41 and the second bite part 42 to maintain the stability of the shape of the polyurethane edge sealing 5 and prevent it from excessively squeezing the rock wool core material 63 due to deformation. The interior of the second bite part 42 is fixedly installed with a polyurethane edge sealing layer 5, and the end of the first bite part 41 is arranged opposite to the end of the second bite part 42.

[0029] The internal reinforcement structure 6 of the exterior wall panel includes a first diagonal rod 61 and a reinforcing plate core 64. Multiple first diagonal rods 61 are fixedly installed inside the wall panel body 1. The side walls of multiple first diagonal rods 61 are fixedly connected to multiple second diagonal rods 62. Multiple diagonal rods 61 are made of aluminum plate material, which is relatively light and can provide effective support force. The first diagonal rod 61 and the second diagonal rod 62 are internally fixedly connected with a rock wool core material 63. The rock wool core material 63 is filled with rock wool material in the gap at the intersection of the first diagonal rod 61 and the second diagonal rod 62, so that the fire resistance of the wall panel body 1 is better. Multiple first diagonal rods 61 obliquely cross the interior of the wall panel 1, which can improve the vertical supporting capacity inside the wall panel body 1, and multiple second diagonal rods 62 are obliquely installed one by one on the inside of two adjacent first diagonal rods 61.

[0030] In this way, the multiple second oblique rods 62 can reinforce the two first oblique rods 61 to reduce the occurrence of compression deformation. The reinforcing plate core 64 is fixedly installed inside the metal panel layer 3, and the reinforcing plate core 64 is fixedly installed inside the bonding layer 2. The reinforcing plate core 64 is made of extruded high-density aluminum plate. The reinforcing plate core 64 is used to improve the strength of the plate body after installation inside the metal panel layer 3 and the bonding layer 2, and it is not easy to be dented and deformed when receiving external pressure and impact. The two ends of the multiple first oblique rods 61 are fixedly connected to the inner wall of the wall panel body 1, and the two ends of the multiple second oblique rods 62 are fixedly connected to the inner side of the wall panel body 1. The two second oblique rods 62 are respectively connected to the two sides of the first oblique rod 61;

[0031] The plurality of diagonal rods 61 are made of aluminum plate material, which is relatively light and can provide effective support. The plurality of first diagonal rods 61 are obliquely across the interior of the wall panel 1, which can improve the vertical support capacity inside the wall panel body 1, and the plurality of second diagonal rods 62 are obliquely installed one by one on the inner side of two adjacent first diagonal rods 61, so that the plurality of second diagonal rods 62 can reinforce the two first diagonal rods 61 and reduce the occurrence of compression deformation. The reinforcing plate core 64 is made of high-density aluminum plate after extrusion. The reinforcing plate core 64 is used to improve the strength of the plate body after installation inside the metal panel layer 3 and the bonding layer 2, and it is not easy to dent and deform when subjected to external pressure and impact. By connecting into a whole reinforced structure, the pressure-bearing capacity inside the wall panel body 1 is greatly improved, thereby making the structure of the assembled rock wool polyurethane edge-sealed exterior wall panel better.

[0032] Working principle:

[0033] When using assembled rock wool polyurethane edge-sealed exterior wall panels to install and fix on the exterior walls of buildings under construction, they can play multiple functions such as strengthening, heat preservation and fire prevention:

[0034] The two exterior wall panels of the assembled rock wool polyurethane edge-sealed exterior wall panel are combined into one structure:

[0035] The first engaging member 41 is designed as a barb-shaped member, and the second engaging member 42 is designed as an inverse barb-shaped member. When assembling two wall panels 1, the first engaging member 41 on one side of one wall panel 1 is aligned with the second engaging member 42 on the other side of the other wall panel 1 and brought close together. The assembly member 43 is made of a vertical and hard aluminum alloy material. The size of the assembly member 43 matches the size of the connecting hole between the first engaging member 41 and the second engaging member 42. The reinforcement core 44 is made of a plurality of high-strength steel bars that vertically penetrate the interior of the assembly member 43. The reinforcement core 44 improves the deformation resistance of the assembly member 43.

[0036] The connection and fixing structure of the two exterior wall panels of the assembled rock wool polyurethane edge-sealed exterior wall panel:

[0037] After the first bite piece 41 and the second bite piece 42 are respectively connected to the two sides of the assembly part 43, the fixing bolt 45 is rotated and screwed into the connection seam between the first bite piece 41 and the second bite piece 42. The end of the fixing bolt 45 is rotated and screwed into the assembly part 43. Then, the fixing bolt 45 drives the outer pressure plate 46 to tightly fit the outer sides of the two adjacent metal panel layers 3 and the bonding layer 2. The squeezing force of the pressure plate 46 is used to fix the first bite piece 41 and the second bite piece 42. The connection between the two assembled rock wool polyurethane edge-sealed exterior wall panels is fixed by the connecting piece, which is more firm and stable than the friction bite connection method.

[0038] The internal structure of the assembled rock wool polyurethane edge-sealed exterior wall panels is strengthened:

[0039] The multiple diagonal rods 61 are made of aluminum plate material, which is relatively light and can provide effective support. The multiple first diagonal rods 61 are obliquely across the interior of the wall panel 1, which can improve the vertical support capacity inside the wall panel body 1, and the multiple second diagonal rods 62 are obliquely installed one by one on the inside of two adjacent first diagonal rods 61. In this way, the multiple second diagonal rods 62 can reinforce the two first diagonal rods 61 to reduce the occurrence of compression deformation. The reinforcement core 64 is made of high-density aluminum plate after extrusion. The reinforcement core 64 is used to improve the strength of the panel after installation inside the metal panel layer 3 and the bonding layer 2. It is not easy to dent and deform when subjected to external pressure and impact. By connecting into a whole reinforcement structure, the pressure-bearing capacity inside the wall panel body 1 is greatly improved.
