Description

Technical Field

[0001] The present invention relates to a wall panel with a cold-formed thin-walled steel thermal break structure, and particularly to a wall panel with a cold-formed thin-walled steel thermal break structure for use in the field of wall panels. Background Technology

[0002] As a building component, wall panels play an irreplaceable role in the construction and home decoration industries. With the popularization of environmental protection concepts, wall panels with thermal break structures have been promoted and used to achieve the thermal insulation function of building walls. However, existing thermal break wall panels generally adopt a sandwich design of inner wall panel-insulation board-outer wall panel. The insulation board is connected to the inner and outer wall panels by adhesive, which can easily lead to an increase in formaldehyde content. At the same time, the curing performance of the adhesive is affected by the ambient temperature, making it difficult to guarantee the stability of the wall panel.

[0003] To address the issues of environmental friendliness and connection stability of wall panels, a certain thermal break wall panel on the market uses a bolted design and has a certain market share.

[0004] Chinese invention patent CN202010779462.3 discloses a thermally broken ultra-low energy consumption exterior wall panel and its construction method. The invention includes an inner wall panel, an insulation interlayer, and an outer wall panel. The inner and outer wall panels are connected and fixed by at least one set of connecting components. Each connecting component includes horizontally symmetrically arranged embedded parts within the inner and outer wall panels. The embedded parts include end plates located on the surfaces of the inner and outer wall panels, embedded anchor bars embedded within the inner and outer wall panels, and connectors located within the insulation interlayer. The connectors are arranged along the thickness direction of the wall panel, with their ends fixed to the end plates. Insulation material is filled between two oppositely arranged connectors, and a connecting plate connects the two opposite connectors. This invention provides strong connection, good insulation effect, and good fire resistance.

[0005] During the installation of the aforementioned wall panels, fixing bolts are required to connect the thermal break gaskets and the frame structure. However, the bolting and disassembly must be done one by one, resulting in a long working time and making it inconvenient to disassemble and reuse the remaining building materials inside the wall panels later. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to ensure the stability of the connection between the thermal break structure and the internal keel of the wall panel, while improving the ease of disassembly and assembly of the two.

[0007] To address the aforementioned problems, this invention provides a wall panel with a cold-formed thin-walled steel thermal break structure, comprising a wall panel core body, with longitudinally and transversely arranged reinforcing ribs installed inside the wall panel core body, a decorative surface layer installed on the outer surface of the wall panel core body, grooves formed on both sides of the wall panel core body, a keel installed inside the wall panel core body, and thermal break components arranged on the inner side of the keel. The thermal break components include steel profiles made of cold-formed thin-walled steel and a nylon thermal insulation layer covering the outer surface of the steel profiles.

[0008] In the aforementioned wall panels with cold-formed thin-walled steel thermal break structures, the design of the mother groove makes it relatively convenient to interlock and splice the core material of the wall panel. In addition, the keel is a 60C type steel keel with high strength characteristics. Together with the reinforcing ribs, it can effectively enhance the wall panel's own support and compressive strength. Compared with the traditional straight type, the cross section of the thermal break component effectively increases the thermal break contact area, ensuring the wall panel's own thermal insulation effect.

[0009] As a further improvement to this application, the thermal break component is connected to the keel by self-tapping bolts, and the keel is designed with a steel mesh.

[0010] As a further improvement of this application, both the broken bridge component and the keel have slots inside. A connecting unit is installed inside the slot, and the connecting unit includes a plug strip that is slidably connected inside the slot. The keel frame has an inner limiting groove that is connected through the slot. The plug strip has a plate groove inside, and a pull plate is slidably connected inside the plate groove. The bottom of the pull plate is coated with a magnetic layer one. The plug strip has a longitudinal groove inside, and the two ends of the longitudinal groove are respectively connected through the inner limiting groove and the bottom of the pull plate. A limiting block is slidably placed inside the longitudinal groove, and the top of the limiting block is coated with a magnetic layer two that attracts the magnetic layer one.

[0011] As a further improvement of this application, a constraint block is installed at the end of the connector away from the broken bridge component, and the constraint block has a notch inside that matches the pull plate.

[0012] As a further improvement of this application, a round rod is installed inside the plate groove, and the pull plate is slidably sleeved on the outer surface of the round rod. A round hole with interference fit to the round rod is provided in the middle of the surface of the pull plate, and the depth of the round hole is less than the thickness of the pull plate.

[0013] As a further improvement of this application, the height of the limiting block is greater than the depth of the inner limiting groove, and the cross-sectional area of ​​the limiting block is not greater than the cross-sectional area of ​​the inner limiting groove. As another improvement of this application, an expansion member is bonded to the inner wall of the inner limiting groove on the side near the broken bridge component, and the expansion member is made of thermal expansion material.

[0014] As a further improvement to this application, the cross-sectional width of the inner limiting groove is greater than that of the longitudinal groove, and in the initial state, there is a horizontal gap between the projection of the limiting block in the vertical direction and the inner walls on both sides of the inner limiting groove.

[0015] In summary, the keel design with reinforcing ribs and steel mesh effectively enhances the compressive strength of the wall panel core material. Furthermore, the steel profiles are made of cold-formed thin-walled steel, and the nylon insulation layer covering their surface is made of PA nylon insulation strips. This ensures that the thermal break component maintains its own deformation resistance while also enhancing the support capacity of the wall panel core material, thus breaking thermal bridges and providing thermal insulation. Additionally, the connection unit employs a double-plane constraint method, strengthening the connection stability between the thermal break component and the keel while providing a more efficient and convenient assembly / disassembly method compared to bolt connections, while ensuring a tight connection between the keel and the thermal break component.

[0018] The three embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0019] Implementation method 1: Figure 1-3 A wall panel with a cold-formed thin-walled steel thermal break structure is shown, including a wall panel core body 1, with longitudinally and transversely arranged reinforcing ribs 4 installed inside the wall panel core body 1, a decorative surface layer 2 installed on the outer surface of the wall panel core body 1, grooves 3 opened on both sides of the wall panel core body 1, a keel 5 installed inside the wall panel core body 1, and a thermal break component 6 arranged inside the keel 5. The thermal break component 6 includes a steel profile 61 made of cold-formed thin-walled steel and a nylon thermal insulation layer 62 covering the outer surface of the steel profile 61. The thermal break component 6 is connected to the keel 5 by bolts and self-tapping screws, and the keel 5 is designed with steel mesh.

[0020] Specifically, the reinforcing ribs 4 and the steel mesh design of the keel 5, and the keel 5 is made of 60C steel, can effectively improve the compressive support capacity of the wall panel core material 1. In addition, the steel section 61 is made of cold-formed thin-walled steel, and the nylon insulation layer 62 covering its surface is made of PA66 nylon insulation strip. This allows the thermal break section 6 to ensure its own deformation resistance while also helping to improve the support capacity of the wall panel core material 1. At the same time, it can also ensure the purpose of breaking the thermal bridge, so that the wall panel core material 1 has a heat insulation effect. It should be added that the self-tapping bolt connection method makes the connection between the thermal break component 6 and the keel 5 relatively convenient.

[0021] The second implementation method: Figure 4-8As shown, components that are the same as or corresponding to those in the first embodiment are represented by reference numerals corresponding to those in the first embodiment. For simplicity, only the differences from the first embodiment will be described below. The difference between the second embodiment and the first embodiment is that: both the broken bridge component 6 and the keel 5 have slots inside, and a connecting unit 7 is installed inside the slot. The connecting unit 7 includes a plug strip 71 that is slidably connected inside the slot. The frame of the keel 5 has an inner limiting groove 72 that is connected through the slot. The plug strip 71 has a plate groove inside, and a pull plate 73 is slidably connected inside the plate groove. The bottom of the pull plate 73 is coated with a magnetic layer one. The plug strip 71 has a longitudinal groove inside, and the two ends of the longitudinal groove are respectively connected through the inner limiting groove 72 and the bottom of the pull plate 73. A limiting block 76 is slidably placed inside the longitudinal groove, and the top of the limiting block 76 is coated with a magnetic layer two that attracts the magnetic layer one.

[0022] A constraint block 75 is installed at one end of the connector 71 away from the broken bridge component 6. The constraint block 75 has a notch inside that matches the pull-out plate 73.

[0023] A round rod 74 is installed inside the plate groove, and a pull plate 73 is slidably sleeved on the outer surface of the round rod 74. A round hole with interference fit with the round rod 74 is provided in the middle of the surface of the pull plate 73, and the depth of the round hole is less than the thickness of the pull plate 73.

[0024] The height of the limiting block 76 is greater than the depth of the inner limiting groove 72, and the cross-sectional area of ​​the limiting block 76 is not greater than the cross-sectional area of ​​the inner limiting groove 72.

[0025] Specifically, to compensate for the low disassembly and assembly efficiency caused by the self-tapping bolt connection method, when connecting the thermal break component 6 and the keel 5, the insert strip 71 is inserted into the slot, and then the exposed end of the pull plate 73 is pulled out of the slot. At this time, the limiting block 76, which loses its magnetic attraction, falls down along the longitudinal groove into the inner limiting groove 72. Due to the height difference between the limiting block 76 and the inner limiting groove 72, the limited block 76 still remains partially inside the insert strip 71 after falling, so that the thermal break component 6 and the keel 5 achieve a double-plane constraint connection, and enhance the connection stability between the thermal break component 6 and the keel 5. After pulling the pull plate 73 out of the slot, place it vertically, align the round hole with the end of the round rod 74, and then rotate the pull plate 73 ninety degrees so that the pull plate 73 is engaged by the notch inside the point-symmetrically arranged constraint block 75. Use the unfolded pull plate 73 to press the nylon heat insulation layer 62 on the surface of the thermal break component 6 to ensure the connection stability between the nylon heat insulation layer 62 and the surface of the steel component 61. When the wall panel needs to be disassembled, rotate the pull plate 73 ninety degrees in the opposite direction to a vertical position, then pull out the pull plate 73 and push it back into the inside of the panel groove. The magnetic attraction causes the limiting block 76 to rise and disengage from the inner limiting groove 72. Then, the plug strip 71 can be pulled out. At this time, the keel 5 and the broken bridge piece 6 can be separated, and the connecting unit 7 can also be reused.

[0026] The third implementation method: Figure 9-11 As shown, components that are the same as or corresponding to those in the second embodiment are referred to by the same reference numerals as those in the second embodiment. For simplicity, only the differences from the second embodiment will be described below. The difference between this third embodiment and the second embodiment is that an expansion member 721 is adhered to the inner wall of the inner limiting groove 72 near the broken bridge member 6, and the expansion member 721 is made of a thermally expanding material.

[0027] The cross-sectional width of the inner limiting groove 72 is greater than that of the longitudinal groove, and in the initial state, the projection of the limiting block 76 in the vertical direction has a horizontal gap with both sides of the inner wall of the inner limiting groove 72.

[0028] Specifically, since the nylon insulation layer 62 has a certain thickness and a certain elasticity, the connection between the keel 5 and the thermal break component 6 needs to maintain a certain degree of compression, which can further ensure the thermal bridge breaking effect. The thermal expansion material used in the expansion component 721 is a material that cannot return to its original shape after thermal expansion, thereby ensuring that the expansion component 721 will shrink under the influence of temperature. After the limiting block 76 falls, the expansion member 721 expands due to the high temperature of the external environment of the wall panel, thus pushing the limiting block 76 and indirectly driving the insertion strip 71 to continue moving towards the end of the slot. This, in turn, causes a small displacement effect on the unfolded pull-out plate 73, so that the pull-out plate 73, which was originally attached to the surface of the nylon insulation layer 62, exerts a certain degree of pressure on the nylon insulation layer 62, strengthening the connection between the thermal break member 6 and the keel 5. Considering current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Various changes made within the knowledge of those skilled in the art without departing from the concept of this application still fall within the protection scope of this invention.
