Description

Technical Field

[0001] This invention relates to the field of thermal insulation exterior wall panels, and more particularly to a prefabricated exterior wall panel with thermal insulation function. Background Technology

[0002] Rock wool exterior wall panels, as a building exterior wall material with high thermal insulation properties, are coated with water-repellent agents during the production process to enhance their waterproof capabilities. However, during heavy rains, a large amount of water adheres to the surface of the rock wool exterior wall panels, causing the water-repellent properties to gradually disappear. This allows moisture to penetrate the rock wool exterior wall panels, weakening their thermal insulation performance. Consequently, heat exchange between the internal insulation areas and the outside environment intensifies, requiring temperature control equipment in the internal insulation areas to operate at higher power to meet temperature control demands, thus increasing building energy consumption. Furthermore, the mechanical structural strength of the rock wool exterior wall panels decreases after absorbing water, leading to the risk of deformation and loosening. Summary of the Invention

[0003] In order to overcome the shortcomings of rock wool wall panels, which are prone to losing their water-repellent ability when exposed to a large amount of water, thus weakening their thermal insulation performance and affecting their mechanical structural strength, this invention provides a prefabricated exterior wall panel with thermal insulation function.

[0004] Technical Solution: A prefabricated exterior wall panel with thermal insulation function includes an insulated exterior wall panel, elastic inserts, pull plates, pressure plates, thermal insulation rubber pads, reinforcing mesh, thermal insulation nails, and a waterproof coating; each insulated exterior wall panel has a movable cavity structure; elastic inserts are slidably connected within the movable cavity structure of the insulated exterior wall panel; pull plates are slidably connected to the front side of the insulated exterior wall panel; pressure plates are slidably connected within the movable cavity structure of the insulated exterior wall panel, closely attached to the rear side of the middle of the corresponding elastic insert; pull plates are fixed to the corresponding pressure plates; thermal insulation rubber pads are filled between the internal space of the movable cavity structure of the insulated exterior wall panel and the pressure plates; insertion holes are respectively provided on the upper and lower sides of the insulated exterior wall panel; thermal insulation... The upper end of the elastic insert of the exterior wall panel is inserted into the corresponding insertion hole structure of the upper exterior wall panel; the lower end of the elastic insert of the exterior wall panel is inserted into the corresponding insertion hole structure of the lower exterior wall panel; a reinforcing mesh is laid between all the exterior wall panels; the reinforcing mesh is fixed to the front surface of the corresponding exterior wall panel by insulation nails; a waterproof coating is applied between all the exterior wall panels, and the waterproof coating covers the reinforcing mesh; an insulation rubber sleeve is fixed in the insertion hole structure of the exterior wall panel, and the insulation rubber sleeve has a sleeve structure that fits on the outer surface of the end of the elastic insert; the end of the elastic insert is inserted into the sleeve structure of the insulation rubber sleeve in the corresponding insertion hole structure.

[0005] More preferably, it also includes a crushing cone; the crushing cone is fixedly attached to the pull plate; a number of protrusions are fixedly attached to the crushing cone, and the front surface of the crushing cone on the pull plate is flush with the front surface of the waterproof coating.

[0006] More preferably, the opening structure of the thermal insulation rubber sleeve is designed as a tightening structure that shrinks inward toward the corresponding thermal insulation exterior wall panel.

[0007] More preferably, each end of the elastic insert has a protrusion structure.

[0008] More preferably, the insulation nails use an insulation material composed of galvanized screws and nylon expansion tubes.

[0009] More preferably, the waterproof coating uses a silicone-acrylic emulsion coating material composed of an organosilicon-acrylic copolymer.

[0010] More preferably, a reinforcing frame is fixed to the pull plate, and the reinforcing frame wraps around the front outer edge of the corresponding thermal insulation exterior wall panel.

[0011] More preferably, a waterproof sealant is applied and cured between the contact areas of two adjacent reinforcing frames.

[0012] More preferably, the front side of the reinforcing frame is designed with a knife-edge structure.

[0013] Beneficial effects: The prefabricated exterior wall panel with thermal insulation function described in this invention is mainly composed of thermal insulation exterior wall panel, thermal insulation nails, reinforcing mesh and waterproof coating. The waterproof coating isolates rainwater intrusion and prevents rainwater from contacting and eroding the internal thermal insulation exterior wall panel, causing the thermal insulation capacity of the exterior wall panel to fail. This allows it to maintain its thermal insulation capacity for a longer period of time, reduces the working pressure of temperature regulation equipment in the thermal insulation area, and reduces building energy consumption.

[0014] The reinforcing mesh is fixed to the surface of the insulated exterior wall panel with insulation nails. In the normal assembly state, each individual insulated exterior wall panel has multiple locking structures with its adjacent panels above and below, allowing the insulated exterior wall panel to be firmly fixed to its adjacent panels through these locking structures. Even if the anchors and adhesive layers fixing the insulated exterior wall panel show signs of aging and loosening, the insulated exterior wall panel is still protected from falling by the adjacent insulated exterior wall panels through the locking structures. When maintenance personnel disassemble the loosened insulated exterior wall panel, they can pull the pull plate to unlock the multiple locking structures in two batches, allowing the loosened insulated exterior wall panel to be easily removed. This improves the technical problem of the risk of rock wool exterior wall panels falling from heights when the anchors and adhesive layers used to fix the rock wool exterior wall panel show signs of aging and loosening.

Detailed Implementation

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] Example 1: A prefabricated exterior wall panel with thermal insulation function in this example, such as... Figures 1-10As shown, the structure includes an insulated exterior wall panel 1, elastic inserts 2, pull plates 3, pressure plates 4, insulated rubber pads 5, reinforcing mesh 7, insulated nails 8, and a waterproof coating 9. Several insulated exterior wall panels 1 are fixed to the wall in an alternating pattern using anchors and adhesive layers. Each insulated exterior wall panel 1 has a movable cavity structure 101. Two elastic inserts 2 are slidably connected within each movable cavity structure 101 of each insulated exterior wall panel 1. A pull plate 3 is slidably connected to the front side of each insulated exterior wall panel 1. A [missing information - likely a specific type of adhesive plate] is slidably connected within each movable cavity structure 101 of each insulated exterior wall panel 1. Pressure plate 4, and pressure plate 4 is closely attached to the rear side of the middle of the two corresponding elastic inserts 2; each pull plate 3 is fixedly connected to the corresponding pressure plate 4; the internal space of the movable cavity structure 101 of each thermal insulation exterior wall panel 1 and the pressure plate 4 are filled with a thermal insulation rubber pad 5; two crushing cones 31 are fixedly connected to each pull plate 3; two insertion hole structures 102 are opened on the upper and lower sides of each thermal insulation exterior wall panel 1; the upper ends of the two elastic inserts 2 of each thermal insulation exterior wall panel 1 are respectively inserted into the insertion hole structures 102 of the two corresponding thermal insulation exterior wall panels 1 on the upper side; the two elastic inserts of each thermal insulation exterior wall panel 1 2. The lower ends are respectively inserted into the corresponding insertion holes 102 of the two lower insulation wall panels 1. In the normal assembly state, the end of each elastic insert 2 and the corresponding insertion hole structure 102 of the insulation wall panel 1 form a locking structure. In this embodiment, each individual insulation wall panel 1 in the non-edge area is provided with eight locking structures between itself and the four adjacent insulation wall panels 1 above and below, so that the insulation wall panel 1 can be firmly fixed together with the four adjacent insulation wall panels 1 above and below through the eight locking structures. Each insulation wall panel 1 has a corresponding aligning pull plate on its front side. The groove structure 103 in the middle of the 3 allows maintenance personnel to pass their hands through the groove structure 103 to reach around to the back of the pull plate 3 and grasp it, making it easier for maintenance personnel to pull out the pull plate 3 with a more powerful grip when disassembling the loose insulation wall panel 1; several reinforcing meshes 7 are laid together between the front surfaces of all insulation wall panels 1; each reinforcing mesh 7 is fixed to the front surface of the corresponding insulation wall panel 1 by several insulation nails 8; a waterproof coating 9 is coated together between the front surfaces of all insulation wall panels 1, and the waterproof coating 9 covers the reinforcing meshes 7.

[0028] All insulation nails 8 use insulation material composed of galvanized screws and nylon expansion tubes, which reduces heat conduction by three-quarters compared to using metal nails directly. This reduces the impact of temperature changes caused by heat transfer from the outside environment to the interior of the insulation wall panel 1 through the insulation nails 8. The waterproof coating 9 uses a silicone-acrylic emulsion coating material composed of an organosilicon-acrylic copolymer. This coating material has excellent hydrophobic properties, as well as excellent wide temperature range stability, UV aging resistance, and chemical corrosion resistance. It is suitable for building exterior walls in various harsh environments and can significantly reduce the impact of external temperature changes on the interior, making indoor temperature changes less noticeable, reducing the workload of indoor temperature control equipment, and lowering the power consumption of temperature control equipment.

[0029] Each insulating exterior wall panel 1 has an insulating rubber sleeve 6 fixedly connected to its insertion structure 102, and the insulating rubber sleeve 6 has a sleeve opening structure 601. The end of each elastic insert 2 is respectively inserted into the sleeve opening structure 601 of the corresponding insertion structure 102. The sleeve opening structure 601 of each insulating rubber sleeve 6 is designed as a tightening structure that shrinks towards the inside of the corresponding insulating exterior wall panel 1, so that the sleeve opening structure 601 of the insulating rubber sleeve 6 has a strong clamping effect on the end of the elastic insert 2 on the side facing the inside of the insulating exterior wall panel 1. Under normal assembly conditions, the insulating rubber sleeve 6 can seal the gap of the insertion structure 102 as much as possible, reduce the heat exchange between the inside and outside through the gap of the insertion structure 102, and improve the insulation effect of the insulating exterior wall panel 1.

[0030] Secondly, the elastic insert 2 is firmly clamped by the side of the sleeve structure 601 of the insulation rubber sleeve 6 facing inwards from the insulation wall panel 1. Conversely, the clamping effect of the side of the sleeve structure 601 of the insulation rubber sleeve 6 away from the inwards from the insulation wall panel 1 is weaker. Therefore, when maintenance personnel disassemble the loose insulation wall panel 1, during the process of pulling the pull plate 3 to pull the end of the elastic insert 2 out of the sleeve structure 601 of the insulation rubber sleeve 6, the end of the elastic insert 2 tends to move further away from the inwards from the sleeve structure 601 of the insulation rubber sleeve 6. The less force is required to pull the end of the elastic insert 2 out of the sleeve structure 601 of the thermal insulation rubber sleeve 6, the easier it is for maintenance personnel to pull the end of the elastic insert 2 out of the sleeve structure 601 of the thermal insulation rubber sleeve 6. Each elastic insert 2 has a protrusion structure 201 at both ends, and the protrusion structure 201 at the end of the elastic insert 2 is firmly inserted into the sleeve structure 601 of the corresponding thermal insulation rubber sleeve 6 facing the inside of the thermal insulation outer wall panel 1, which improves the firmness of the end of the elastic insert 2 in the sleeve structure 601 of the thermal insulation rubber sleeve 6 under normal assembly conditions.

[0031] The normal assembly state of a prefabricated exterior wall panel with thermal insulation function in this embodiment is as follows: all thermal insulation exterior wall panels 1 are fixed to the wall by anchors and adhesive layers. All thermal insulation exterior wall panels 1 are staggered in the left-right direction. Therefore, each individual thermal insulation exterior wall panel 1 located in the non-edge area is adjacent to four thermal insulation exterior wall panels 1 on its upper and lower sides. The upper ends of the two elastic inserts 2 of each thermal insulation exterior wall panel 1 are respectively inserted into the corresponding insertion holes 102 of the two upper thermal insulation exterior wall panels 1, and the lower ends of the two elastic inserts 2 of each thermal insulation exterior wall panel 1 are respectively inserted into the corresponding insertion holes 102 of the two lower thermal insulation exterior wall panels 1. Correspondingly, the insertion holes 102 of each thermal insulation exterior wall panel 1 contain elastic inserts 2 of adjacent thermal insulation exterior wall panels 1. Each elastic insert 2... Each end of the insulated exterior wall panel 1 and the corresponding insertion hole structure 102 form a locking structure. Therefore, there are a total of eight locking structures between the insulated exterior wall panel 1 and the four adjacent insulated exterior wall panels 1. Several reinforcing nets 7 are laid between the front sides of all the insulated exterior wall panels 1. The reinforcing nets 7 are fixed to the corresponding insulated exterior wall panels 1 by insulation nails 8. The reinforcing nets 7 can strengthen the tight connection between adjacent insulated exterior wall panels 1. At the same time, they serve as a collision protection net frame covering the front side of the insulated exterior wall panels 1, improving the structural strength of the overall prefabricated exterior wall. A waterproof coating 9 is applied between the front sides of all the insulated exterior wall panels 1. The waterproof coating 9 can reduce the penetration of external moisture into the interior of the insulated exterior wall panels 1, improving the service life and insulation effect of the insulated exterior wall panels 1.

[0032] Example 2, based on Example 1, such as Figures 1-8 As shown, in this embodiment, a breaking cone block 31 is also included; a breaking cone block 31 is fixedly attached to a pull plate 3; a plurality of protrusions 32 are fixedly attached to the breaking cone block 31; the front surface of the breaking cone block 31 on the pull plate 3 is flush with the front surface of the waterproof coating 9; the area where the pull plate 3 of each thermal insulation exterior wall panel 1 is located can be accurately determined by the breaking cone block 31 exposed from the waterproof coating 9; a plurality of protrusions 32 are fixedly attached to each breaking cone block 31, and all protrusions 32 are covered by the waterproof coating 9 to avoid the safety hazard of being stabbed by passers-by due to the protrusions 32 being exposed outside the waterproof coating 9.

[0033] The disassembly of a prefabricated exterior wall panel with thermal insulation function in this embodiment is as follows: When the anchors and adhesive layer of a certain thermal insulation exterior wall panel 1 become loose, the thermal insulation exterior wall panel 1 will swing forward back and forth under the action of external wind pressure, posing a safety hazard of falling. At this time, the breaking cone 31 and the spike 32 connected to the pull plate 3 of the thermal insulation exterior wall panel 1 will continuously swing back and forth with it. Therefore, the breaking cone 31 and the spike 32, which swing back and forth, will puncture the waterproof coating 9 covering its surface. In this way, the maintenance personnel will clearly observe that there is a large damaged area of ​​the waterproof coating 9 in the area aligned with the breaking cone 31, and know that the corresponding thermal insulation exterior wall panel 1 needs to be repaired and replaced. During the disassembly of the loose thermal insulation exterior wall panel 1, the maintenance personnel first remove the reinforcing mesh 7, thermal insulation nails 8 and waterproof coating 9 on the front side of the thermal insulation exterior wall panel 1, so that the thermal insulation exterior wall panel 1 is exposed to the outside air. Then, the maintenance personnel pull the pull plate 3 to move the pressure plate 4 forward. The pressure plate 4 moves the thermal insulation rubber. The pad 5 is compressed forward, while the pressure plate 4 pushes the middle of the two corresponding elastic inserts 2 forward, causing the elastic inserts 2 to be in a C-shaped structure that bends forward in the middle. This causes the two ends of the elastic inserts 2 to converge towards the middle and leave the corresponding insertion hole structure 102 of the insulation wall panel 1. This completes the unlocking of the four locking structures between the insulation wall panel 1 and the four adjacent insulation wall panels 1. At this point, only four locking structures remain locked between the insulation wall panel 1 and the four adjacent insulation wall panels 1. Maintenance personnel can then directly... Continue pulling the pull plate 3 to move the insulated exterior wall panel 1 forward. Since the end of the elastic insert 2 has deformation elastic force, the insertion hole structure 102 of the insulated exterior wall panel 1 will be forcibly separated from the elastic insert 2 in the adjacent insulated exterior wall panel 1 during the forward movement. This will complete the unlocking of the remaining four locking structures of the insulated exterior wall panel 1, and realize the unlocking of eight locking structures in two batches. This will allow the loosened insulated exterior wall panel 1 to be easily removed and replaced.

[0034] Example 3, based on Example 1, such as Figures 1-7As shown, in this embodiment, each pull plate 3 is fixedly connected to a reinforcing frame 33, and the reinforcing frame 33 wraps around the outer edge of the front side of the corresponding thermal insulation wall panel 1. The reinforcing frame 33 can provide anti-collision protection for the outer edge area of ​​the front side of the thermal insulation wall panel 1, and improve the overall structural strength of the front side of the thermal insulation wall panel 1. In the normal assembly state, waterproof sealant is applied and solidified between the contact areas of every two adjacent reinforcing frames 33, which increases the gap between the two adjacent thermal insulation wall panels 1 and prevents moisture from entering inward. The protective effect against penetration: The front side of the reinforcing frame 33 aligned with the edge area of ​​each insulated exterior wall panel 1 is equipped with a blade structure 3301. When maintenance personnel are disassembling a loose insulated exterior wall panel 1, when the maintenance personnel pull the pull plate 3 forward, the pull plate 3 drives the reinforcing frame 33 forward away from the insulated exterior wall panel 1. At the same time, the reinforcing frame 33 cuts the waterproof sealant solidified on its surface through the blade structure 3301, so that the reinforcing frame 33 will not be blocked by the waterproof sealant and can move forward smoothly away from the insulated exterior wall panel 1.
