Description

Technical Field

[0001] This application relates to the field of thermal insulation wall technology, specifically to prefabricated thermal insulation wall structures for zero-carbon buildings. Background Technology

[0002] Currently, the thermal insulation and decorative properties of building envelopes have become the focus of building energy conservation research. Internal insulation technology is gradually being replaced by external wall insulation technology, which is being promoted and applied more and more gradually.

[0003] An existing patent (publication number: CN219992798U) discloses a zero-carbon prefabricated insulated wall structure designed to improve the structural strength and fire-resistant insulation performance of the wall. It consists of a fire-resistant insulated main board with high-strength fire-resistant insulated sub-boards on both sides to form a fire-resistant insulated wall. Steel wire mesh is fixed to both sides of the wall via horizontally spaced, through-type non-metallic thermal break bridge connectors and end-mounted limiting fastening discs. Limiting pads are embedded inside the steel wire mesh between the limiting fastening discs to restrict the distance to the sub-boards. A crack-resistant leveling mortar layer is applied to the outer side of the sub-boards, and a decorative layer is applied to the outer side of the crack-resistant leveling mortar layer. High-strength fire-resistant insulated sub-boards are bonded to both sides of the fire-resistant insulated main board. This design offers advantages such as suitability for rapid on-site assembly and construction, good wall stability and insulation performance, high overall structural strength, good weather resistance and fire resistance, and long service life.

[0004] Although the device in the aforementioned comparative document has solved the problem that the wall structure strength and fireproof and thermal insulation performance are still insufficient, when the device is in use, there is no mutual restraint structure between adjacent insulation boards or fireproof boards, the connection strength between the boards is poor, and the overall connection is weak. In order to solve the above problems, a zero-carbon building prefabricated thermal insulation wall structure is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a zero-carbon prefabricated insulated wall structure with advantages such as mutual restraint structure, which solves the problems of poor connection strength and weak overall connectivity between adjacent insulation boards or fireproof boards due to the lack of mutual restraint structure between them.

[0006] To achieve the above objectives, this application provides the following technical solution: a zero-carbon building prefabricated insulated wall structure, including a wall, wherein multiple insulation boards and fireproof boards are provided on the front side of the wall; Multiple connectors are provided between the insulation boards and between the insulation board and the fireproof board. Each connector has a mounting ear plate and a limiting plate fixedly connected to its two ends. The mounting ear plate is fixed to the front of the wall with bolts. The insulation board includes a first frame, and the fireproof board includes a second frame. The first and second frames have identical surface structures. The first frame has two first limiting grooves at its top and bottom, and two second limiting grooves at its four corners. Multiple limiting plates are located within the first and second limiting grooves. The first frame has two top grooves at its top, two bottom connecting blocks at its bottom, and side connecting blocks and side grooves on its sides. The insulation board and the fireproof board are staggered vertically. The connectors are positioned at the joints of the staggered joints.

[0007] The above scheme enhances the connection between the upper and lower layers of boards by interlocking the top groove and the bottom connecting block, and enhances the connection between adjacent boards by interlocking the side connecting block and the side groove. The interlocking connection between boards reduces thermal bridging at joints, improving overall insulation performance. The staggered splicing design of the insulation board and fireproof board disperses stress concentration at joints, enhancing the wall's crack resistance and seismic performance. The design of connectors, mounting ears, and limiting plates enables rapid positioning and fixing of the insulation board, fireproof board, and wall, simplifying the assembly process. The first and second limiting grooves of the first and second frames ensure a tight fit between the connectors and the first and second frames, improving structural stability. The connectors positioned at staggered joints further strengthen the mechanical strength of the joints, preventing deformation and cracking caused by thermal expansion and contraction or external forces.

[0008] Furthermore, fireproof cotton is installed inside the second frame.

[0009] The above-mentioned solution, which involves filling the fireproof board with fireproof cotton, can significantly improve the fire resistance rating of the wall.

[0010] Furthermore, the fireproof board is installed as a layer of fireproof board on a four-layer insulation board.

[0011] The above solution, which uses four layers of insulation boards and one layer of fireproof board in an alternating arrangement, ensures both insulation performance and blocks the spread of fire through the fireproof layer, thus meeting the requirements of building fire protection codes.

[0012] Furthermore, the front surfaces of the insulation board and fireproof board are sequentially provided with a leveling mortar layer, a crack-resistant mesh, another leveling mortar layer, and a decorative layer.

[0013] The above solution, through the composite structure of leveling mortar layer and crack-resistant mesh, can enhance the wall's crack resistance and impact resistance, prevent surface cracking caused by temperature changes or external forces, provide an aesthetic effect through the decorative layer, and protect the internal structure from environmental erosion.

[0014] Furthermore, when the anti-crack netting mentioned above comes into contact with the anti-crack netting below, they should be pressed together by at least 10cm.

[0015] By using the above-mentioned design, which involves pressing the crack-resistant mesh together at least 10cm from top to bottom, the continuity of the crack-resistant mesh at the joints can be ensured, avoiding local weak points caused by construction errors and improving the overall crack resistance.

[0016] Furthermore, a metal support layer is provided inside the first frame, and a first insulation layer and a second insulation layer are respectively provided on opposite sides of the metal support layer.

[0017] The above scheme, by setting a metal support layer, can serve as the core load-bearing structure, which can enhance the mechanical strength of the insulation board. It is suitable for high-rise buildings or large-span walls. Through the double-layer design of the first and second insulation layers, different insulation materials can be combined to achieve efficient heat insulation and energy saving.

[0018] Furthermore, a sound insulation layer is provided on the side of the first insulation layer, and a flame retardant layer is provided on the side of the second insulation layer.

[0019] The above solution, which uses porous sound-absorbing material in the sound insulation layer, can effectively absorb mid-to-high frequency noise and improve the sound insulation performance of the wall.

[0020] Furthermore, the sound insulation layer is disposed on the outermost layer inside the first frame, and the flame retardant layer is disposed on the innermost layer inside the first frame.

[0021] By using the above method, and placing a sound insulation layer on the outer layer, external noise can be blocked from entering.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects: This zero-carbon prefabricated insulated wall structure enhances the connection between upper and lower layers of panels through the interlocking of top grooves and bottom connecting blocks. The interlocking of side connecting blocks and side grooves further strengthens the connection between adjacent panels. This interlocking connection reduces thermal bridging at joints, improving overall insulation performance. The staggered splicing design of the insulation and fireproof boards disperses stress concentration at joints, enhancing the wall's crack resistance and seismic performance. The design of connectors, mounting ears, and limiting plates enables rapid positioning and fixing of the insulation and fireproof boards to the wall, simplifying the assembly process. The first and second limiting grooves of the first and second frames ensure a tight fit between the connectors and the frames, improving structural stability. Connectors positioned at staggered joints further strengthen the mechanical strength of the joints, preventing deformation and cracking caused by thermal expansion and contraction or external forces.

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Please see Figure 1 , Figure 2 and Figure 5 The zero-carbon building prefabricated insulated wall structure in this embodiment includes a wall 1, and multiple insulation boards 2 and fireproof boards 3 are provided on the front of the wall 1. Multiple connectors 5 are provided between the insulation boards 2 and the fireproof board 3. Multiple connectors 5 are also provided between the insulation boards 2 and the fireproof board 3. Mounting ears 501 and limiting plates 502 are fixedly connected to both ends of each connector 5. The mounting ears 501 are fixed to the front of the wall 1 by bolts. The insulation board 2 includes a first frame 201, and the fireproof board 3 includes a second frame 301. The first frame 201 and the second frame 301 have the same surface structure. The first frame 201 has two first limiting grooves 207 at its top and bottom. The four corners of the front of the first frame 201 are... A second limiting groove 208 is provided, and multiple limiting plates 502 are respectively located in the first limiting groove 207 and the second limiting groove 208. Two top grooves 209 are provided on the top of the first frame 201, and two bottom connecting blocks 2010 are provided on the bottom of the first frame 201. Side connecting blocks 2011 and side grooves 2012 are provided on the sides of the first frame 201. The insulation board 2 is staggered vertically, and the insulation board 2 and the fireproof board 3 are also staggered vertically. The connector 5 is located at the joint of the staggered joint, and passes through the top groove 209. The interlocking of 9 with the bottom connecting block 2010 enhances the connection between the upper and lower layers of boards. The interlocking of the side connecting block 2011 with the side groove 2012 enhances the connection between adjacent boards. This interlocking connection method reduces thermal bridging at joints, improving overall insulation performance. The staggered splicing design of the insulation board 2 and fireproof board 3 disperses stress concentration at joints, enhancing the crack resistance and earthquake resistance of the wall 1. The connection is achieved through connector 5 and mounting ear plate 5. The design of 01 and the limiting plate 502 enables rapid positioning and fixing of the insulation board 2, fireproof board 3 and wall 1, simplifying the assembly process. The design of the first limiting groove 207 and the second limiting groove 208 of the first frame 201 and the second frame 301 ensures a tight fit between the connector 5 and the first frame 201 and the second frame 301, which can improve structural stability. By setting the connector 5 at the misaligned joint, the mechanical strength of the joint can be further strengthened, which can prevent deformation and cracking caused by thermal expansion and contraction or external force.

[0027] Please see Figure 3 and Figure 4 The second frame 301 is internally equipped with fireproof cotton. The design of filling the fireproof board 3 with fireproof cotton significantly improves the fire resistance rating of the wall 1. The fireproof board 3 is positioned with one layer of fireproof board 3 on top of four layers of insulation board 2. This alternating arrangement of four layers of insulation board 2 and one layer of fireproof board 3 ensures insulation performance while blocking the spread of fire through the fireproof layer, meeting building fire safety requirements. The front surfaces of the insulation board 2 and fireproof board 3 are sequentially equipped with a leveling mortar layer 6, a crack-resistant mesh 4, another leveling mortar layer 6, and a decorative layer 7. The composite structure of the leveling mortar layer 6 and the crack-resistant mesh 4 enhances the wall's crack resistance and impact resistance, preventing surface cracking due to temperature changes or external forces. The decorative layer 7 provides an aesthetic effect while protecting the internal structure from environmental erosion. When the upper and lower crack-resistant mesh 4 come into contact, they must be pressed together by at least 10cm. This design ensures the continuity of the crack-resistant mesh 4 at the joints, avoiding problems caused by construction errors. To address localized weaknesses and enhance overall crack resistance, a metal support layer 202 is installed inside the first frame 201. A first insulation layer 203 and a second insulation layer 204 are respectively installed on opposite sides of the metal support layer 202. The metal support layer 202 serves as the core load-bearing structure, enhancing the mechanical strength of the insulation board 2. This design is suitable for high-rise buildings or large-span walls 1. The double-layer design of the first insulation layer 203 and the second insulation layer 204 allows for the combination of different insulation materials, achieving efficient heat insulation and energy saving. A sound insulation layer 205 is installed on the side of the first insulation layer 203, and a flame-retardant layer 206 is installed on the side of the second insulation layer 204. The sound insulation layer 205, made of porous sound-absorbing material, effectively absorbs mid-to-high frequency noise, improving the sound insulation performance of the wall 1. The sound insulation layer 205 is located on the outermost layer inside the first frame 201, while the flame-retardant layer 206 is located on the innermost layer. The sound insulation layer 205, located on the outermost layer, effectively blocks external noise from entering.

[0028] In this embodiment, the interlocking of the top groove 209 and the bottom connecting block 2010, and the interlocking of the side connecting block 2011 and the side groove 2012, enhances the connectivity between the panels. The interlocking connection reduces thermal bridging at the joints, improving overall insulation performance. The staggered splicing design of the insulation board 2 and the fireproof board 3 disperses stress concentration at the joints, enhancing the crack resistance and earthquake resistance of the wall 1. The design of the connector 5, mounting ear plate 501, limiting plate 502, first limiting groove 207, and second limiting groove 208 achieves insulation. The rapid positioning and fixing between the board 2, fireproof board 3 and wall 1 ensures a tight fit between the connector 5 and the first frame 201 and the second frame 301, improving structural stability. By placing the connector 5 at the staggered joint, the mechanical strength of the joint can be further enhanced, preventing deformation and cracking caused by thermal expansion and contraction or external forces. Through staggered splicing, multi-layer composite structure and optimized combination of fireproof and soundproof materials, this device can achieve efficient construction, high thermal insulation, strong fire resistance and excellent sound insulation of prefabricated insulated walls, while taking into account structural stability and durability, meeting the requirements of green building and zero-carbon goals.

[0029] The working principle of the above embodiment is as follows: In use, multiple insulation boards 2 or fireproof boards 3 can be installed sequentially from left to right by interlocking the side connecting block 2011 and the side groove 2012. Then, four layers of insulation boards 2 and one layer of fireproof boards 3 can be installed sequentially from top to bottom by interlocking the top groove 209 and the bottom connecting block 2010. When splicing the upper and lower boards, the connecting piece 5 is installed on the front of the wall 1 by bolts and mounting ear plate 501. When splicing the upper and lower boards, the position of the limiting plate 502 is placed within the first limiting groove 207 and the second limiting groove 208, which can enable quick positioning and fixing of the insulation board 2, fireproof board 3 and wall 1. Then, four layers of insulation boards 2 and one layer of fireproof boards 3 can be installed sequentially. After installation, a leveling mortar layer 6 is applied to the surface of the insulation board 2 and the fireproof board 3. Then, the crack-resistant mesh 4 is pasted onto the surface of the insulation board 2 and the fireproof board 3. After pasting, another leveling mortar layer 6 is applied. Then, the decorative layer 7 is pasted onto the surface of the crack-resistant mesh 4. After pasting, the composite structure of the leveling mortar layer 6 and the crack-resistant mesh 4 can enhance the crack resistance and impact resistance of the wall, prevent surface cracking caused by temperature changes or external forces, and provide an aesthetic effect through the decorative layer 7, while protecting the internal structure from environmental erosion.
