Description

Technical Field

[0001] This invention relates to the field of building wall insulation technology, specifically to an insulated wall structure. Background Technology

[0002] In modern architecture, to reduce overall building energy consumption, wall design typically needs to consider thermal insulation performance, requiring the inclusion of insulation layers within the wall structure to form insulated walls. These wall insulation layers are usually made of porous materials (such as aerogel-based materials) in the form of insulation boards. The material and performance of these boards differ significantly from other materials, easily leading to adhesion failure and resulting in wall hollowing, cracking, or even detachment. This greatly reduces the lifespan and safety of the insulated walls.

[0003] To prevent the wall insulation layer from delaminating and detaching, many existing technologies extensively employ metal fasteners that penetrate or partially penetrate the insulation layer for reinforcement. While this achieves both fixation and prevention of delamination, the penetrating metal fasteners create thermal bridges, significantly reducing the insulation performance of the insulation layer. Moreover, under the thermal stress of the wall, these fasteners within the insulation layer can continuously cause damage.

[0004] Especially for aerogel insulation layers, which are thinner and have lower structural resistance, the semi-penetrating and other fixing methods are more difficult to control the penetration depth, making it easier to form thermal bridges or cause defects such as poor fixation and damage to the aerogel insulation layer itself.

[0005] To address the aforementioned issues, how to achieve wall insulation without adding additional thermal bridges, and how to better prevent hollowing, peeling, and cracking, has become a problem that those skilled in the art need to consider and solve. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is: how to provide a thermal insulation wall structure that can avoid thermal bridging and reduce thermal insulation performance, better prevent insulation layer delamination and cracking, and provide better thermal insulation effect.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An insulated wall structure includes a wall with an outer decorative layer on its outer surface. The wall is characterized in that an inner cement mortar layer, an insulation board, an outer cement mortar layer, and an interior decorative layer are sequentially arranged outwards on the inner side of the wall between two floor slabs. A fixing frame is embedded in the inner cement mortar layer and extends vertically along the entire inner wall surface. The insulation board is fixed to the fixing frame.

[0008] In this design, the wall structure is an internal insulation structure. The insulation board is located between the upper and lower floor slabs on the inner side of the wall, and the area requiring fixation is small, making it easier to secure. Furthermore, a fixing frame is added within the inner cement mortar layer, allowing the insulation board to be relatively fixed to the frame. This significantly improves the fixation effect of the insulation board, better preventing it from peeling off from the cement mortar layer, and better avoiding hollowing and cracking of the insulation layer.

[0009] Furthermore, the insulation board is made of aerogel material. It has advantages such as light weight and good thermal insulation, thus better ensuring the insulation effect.

[0010] Furthermore, the mounting bracket is a metal frame with a grid-like structure.

[0011] In this way, the mounting bracket has sufficient structural strength as a fixing base, and the pre-installation and fixing of the mounting bracket can be better realized.

[0012] Furthermore, the upper and lower ends of the fixing frame have a vertically outward folding section, and the folding section is pre-fixed to the corresponding floor slab by vertically set threaded parts.

[0013] This method relies on a fixed frame as a foundation, with both ends of the frame pre-fixed to the floor slab, ensuring the reliability of the fixed foundation and preventing the formation of external thermal bridges.

[0014] Furthermore, an inner fixing net is fixedly installed vertically on the outside of the fixing frame, and an outer fixing net that spreads vertically is embedded in the outer cement mortar layer. Rows of pull wires are fixedly connected between the inner fixing net and the outer fixing net to clamp the insulation board.

[0015] In this way, a layer of fixing mesh is installed on both the inner and outer sides of the insulation board. This mesh is tightened by rows of guy wires, clamping and securing the insulation board. This ensures that all parts of the insulation board are firmly held and reinforced, better preventing hollowing and detachment caused by thermal expansion and contraction of the insulation material. Simultaneously, the embedded fixing frames and mesh within the inner and outer cement mortar layers create a skeletal effect, further strengthening the cement mortar layer and preventing cracking and detachment. Therefore, this solution significantly strengthens and secures the insulation wall structure without creating external thermal bridges, effectively preventing hollowing and cracking of the insulation layer, and providing superior insulation performance.

[0016] Furthermore, the internal fixing mesh is a metal mesh structure and is welded and fixed to the metal frame.

[0017] This ensures better and more reliable fixation between the fixing frame and the inner fixing net.

[0018] Furthermore, the inner fixing net is welded and fixed at both ends to the outer ends of the folded sections at both ends of the fixing frame. There are also several reinforcing connecting rods evenly distributed in a dot matrix arrangement between the fixing frame and the inner fixing net. The reinforcing connecting rods are made of metal and their inner ends are welded to the fixing frame, while their outer ends are welded to the inner fixing net.

[0019] This better ensures the overall stability of the internal fixing net and serves as a better foundation for the stress support of the guy wires.

[0020] Furthermore, the outer side of the fixing frame is attached to the inner side of the wall, and the inner fixing mesh is embedded in the outer surface of the inner cement mortar layer. This makes it easier to smooth the inner cement mortar layer during construction, while avoiding interference and damage to the inner cement mortar layer caused by the pulling of the wire.

[0021] Furthermore, the insulation board is a rectangular plate structure and consists of multiple horizontally arranged boards, while the pull wires are arranged vertically in the gaps between adjacent insulation boards.

[0022] This allows for better fixation of the insulation boards and facilitates the installation of guy wires and adjustment devices, preventing damage to the integrity of the insulation boards. In practice, the insulation boards are preferably arranged with a width of approximately 1-3 meters, and their height is consistent with the height of the upper and lower floor slabs.

[0023] Furthermore, a passive adjustment device is also provided on the pull line. The passive adjustment device includes a disc-shaped outer shell with an inlet and an outlet arranged opposite each other along the diameter direction on the outer shell. Two spring plates are provided inside the outer shell. The middle of the spring plates is S-shaped and the two end supports are bent and fitted to the inner wall of the outer shell, so that an S-shaped channel is formed between the two spring plates, connecting the inlet and outlet of the outer shell. The pull line passes through and is tightened in the S-shaped channel.

[0024] In this way, the pull wire runs through and is taut within the S-shaped channel formed by the two spring plates. The pull wire forms an S-shape with a bending angle smaller than the channel itself, creating two contact points with the spring plates on either side. When the pull wire is taut, the S-shapes of the two spring plates deform, generating a force that interacts with the pull wire. Thus, when the wall structure cools (due to thermal expansion and contraction), causing the insulation board material to shrink and the distance between the inner and outer fixing meshes to shorten, the pull wire can be tightened again by the deformation of the spring plates. Conversely, when the wall structure heats, causing the insulation board material to expand and the distance between the inner and outer fixing meshes to increase, the deformation of the two spring plates can extend the effective length of the pull wire, achieving passive adaptive adjustment and consistently ensuring the tight fixation of the insulation board. Meanwhile, the unique structural design of the spring sheet allows its S-shaped shape to deform and provide deformation output when initially subjected to tension pressure on one side of the S-shaped channel. When the pressure increases, the two ends of the spring sheet are squeezed together in opposite directions, further increasing the deformation output. This achieves a dual deformation output effect and greatly improves the adjustable range of the adjustment device.

[0025] Furthermore, an active adjustment device is also provided on the pull line. The active adjustment device includes a cylindrical protective shell arranged along the length of the pull line. The protective shell has elastic skins at both ends. Inside the protective shell, a multi-segment shape memory alloy with a tortuous structure is arranged in the middle along the length direction. The shape memory alloy segments are connected to form a continuously tortuous whole with a gradually increasing deformation temperature (from -10℃ to 45℃). Each shape memory alloy segment can flatten and elongate when it reaches the deformation temperature. The pull line can be movably passed through the elastic skin and connected to both ends of the shape memory alloy.

[0026] In this way, when the wall temperature changes between hot and cold, as the temperature gradually rises, each segment of shape memory alloy can gradually flatten and elongate with the increase in temperature, thereby extending the effective length of the pull wire so that it can follow the thermal expansion of the wall material; similarly, when the temperature drops, the pull wire can tighten with the contraction of the wall, realizing active adaptive adjustment and always ensuring the tension and fixation effect of the insulation board.

[0027] Furthermore, the outer end of the pull wire is inclined downwards.

[0028] This extended length of the guy wire facilitates the installation of the adjustment device and the achievement of its adjustment effect. Simultaneously, the guy wire provides an upward tensile force to the external fixing mesh, which can share some of the weight of the cement mortar and interior layer. Since the cement mortar and insulation layer are bonded together, reducing the gravitational force can better mitigate the risk of interlayer bond failure.

[0029] Furthermore, the insulated wall structure is constructed using the following steps: First, make a fixed frame, inner fixed net and outer fixed net of the corresponding height according to the distance between the upper and lower floor slabs. Then, complete the welding between the fixed frame and the inner fixed net, and complete the connection between the inner fixed net and the pull line at the preset position (passive adjustment device and / or active adjustment device are pre-connected to the pull line). b. Complete the installation of the fixing frame and the inner fixing mesh, so that the outer side of the fixing frame is attached to the inner side of the wall, and fix the upper and lower ends of the fixing frame to the upper and lower floor slabs through the mesh holes of the inner fixing mesh using threaded parts; c. Apply cement mortar to the wall through the mesh of the internal fixing mesh. The cement mortar should completely fill and cover the fixing frame until it is flush with the internal fixing mesh, ensuring no air bubbles or gaps, and avoiding the wires being covered by cement mortar to form an inner cement mortar layer. d. Lay the pre-cut insulation boards (bonded) on the outside of the inner cement mortar layer, so that the pull wires set along the vertical row are exactly between the adjacent insulation boards. Pull the outer end of the pull wires out of the outside of the insulation board, and lay the outer fixing net on the outside of the insulation board. Complete the connection between the outer end of the pull wires and the outer fixing net, and press the insulation board tightly to fix it. e. Use gap filler to fill the gaps that may exist between adjacent insulation boards through the mesh of the external fixing mesh. Then apply cement mortar to the outside of the insulation board so that it enters the mesh of the external fixing mesh and completely covers the external fixing mesh. Smooth it to form an external cement mortar layer. After the exterior cement mortar layer has cured, the interior layer is then applied to complete the construction.

[0030] In this way, you can easily and quickly complete the construction of each material layer throughout the entire construction process, ensuring the realization of the functions of each part of the wall structure.

[0031] In summary, this invention enhances the overall bonding performance, load-bearing capacity, and toughness of the cement mortar layer. By fixing the insulation layer with string lines, it shares the wall load and continues to provide insulation layer fixation even after adhesive failure. This achieves wall insulation without adding additional thermal bridges, and better prevents hollow areas, detachment, and cracking, resulting in higher wall strength and better insulation performance.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] Preferred embodiment: A thermal insulation wall structure, see [link / reference] Figures 1-3 As shown, the wall includes a wall 1, and an exterior decorative layer 2 is provided on the outer surface of the wall 1. The inner side of the wall, located between the upper and lower floor slabs, is provided with an inner cement mortar layer 3, an insulation board 4, an outer cement mortar layer 5, and an interior decoration layer 6 in sequence. A fixing frame 7 is embedded in the inner cement mortar layer 3 and extends vertically along the entire inner wall surface. The insulation board 4 is fixed to the fixing frame.

[0037] In this design, the wall structure is an internal insulation structure. The insulation board is located between the upper and lower floor slabs on the inner side of the wall, and the area requiring fixation is small, making it easier to secure. Furthermore, a fixing frame is added within the inner cement mortar layer, allowing the insulation board to be relatively fixed to the frame. This significantly improves the fixation effect of the insulation board, better preventing it from peeling off from the cement mortar layer, and better avoiding hollowing and cracking of the insulation layer.

[0038] The insulation board 4 is made of aerogel material. It has advantages such as light weight and good heat insulation, thus better ensuring the heat preservation effect.

[0039] The fixing frame 7 is a metal frame with a grid structure.

[0040] In this way, the mounting bracket has sufficient structural strength as a fixing base, and the pre-installation and fixing of the mounting bracket can be better realized.

[0041] The fixing frame 7 has a vertically outward folding section 12 at both the upper and lower ends, and the folding section 12 is fixed to the corresponding floor slab by a vertically set threaded part 13.

[0042] This method relies on a fixed frame as a foundation, with both ends of the frame pre-fixed to the floor slab, ensuring the reliability of the fixed foundation and preventing the formation of external thermal bridges.

[0043] The fixing frame 7 is vertically fixed with an inner fixing net 9, and the outer cement mortar layer is embedded with an outer fixing net 10 that is vertically spread. The inner fixing net 9 and the outer fixing net 10 are fixedly connected by rows of pull wires 11 to clamp the insulation board.

[0044] In this way, a layer of fixing mesh is installed on both the inner and outer sides of the insulation board. This mesh is tightened by rows of guy wires, clamping and securing the insulation board. This ensures that all parts of the insulation board are firmly held and reinforced, better preventing hollowing and detachment caused by thermal expansion and contraction of the insulation material. Simultaneously, the embedded fixing frames and mesh within the inner and outer cement mortar layers create a skeletal effect, further strengthening the cement mortar layer and preventing cracking and detachment. Therefore, this solution significantly strengthens and secures the insulation wall structure without creating external thermal bridges, effectively preventing hollowing and cracking of the insulation layer, and providing superior insulation performance.

[0045] The internal fixing mesh 9 is a metal mesh structure and is welded and fixed to the metal frame.

[0046] This ensures better and more reliable fixation between the fixing frame and the inner fixing net.

[0047] During implementation, the external fixing mesh is also a metal mesh structure to ensure sufficient compressive strength to the insulation board.

[0048] The inner fixing mesh 9 is welded and fixed at both ends to the outer ends of the folded sections 12 at both ends of the fixing frame. Several reinforcing connecting rods 14, arranged in a dot matrix, are evenly distributed between the fixing frame 7 and the inner fixing mesh 9. The reinforcing connecting rods 14 are made of metal, with their inner ends welded to the fixing frame 7 and their outer ends welded to the inner fixing mesh 9. This design better ensures the overall fixing strength of the inner fixing mesh and better serves as the load-bearing support foundation for the guy wire.

[0049] The outer side of the fixing frame 7 is attached to the inner side of the wall 1, and the inner fixing mesh 9 is embedded in the outer surface of the inner cement mortar layer 3. This makes it easier to smooth the inner cement mortar layer during construction, while avoiding interference and damage to the inner cement mortar layer caused by the pulling of the wire.

[0050] The insulation board 4 is a rectangular plate structure and consists of multiple horizontally arranged boards, while the pull wires 11 are arranged vertically in the gaps between adjacent insulation boards 4.

[0051] This allows for better fixation of the insulation boards and facilitates the installation of guy wires and adjustment devices, preventing damage to the integrity of the insulation boards. In practice, the insulation boards are preferably arranged with a width of approximately 1-3 meters, and their height is consistent with the height of the upper and lower floor slabs.

[0052] In practice, a passive adjustment device is also provided on the pull wire 11. The passive adjustment device includes a disc-shaped outer shell 15. The outer shell 15 has an outer shell inlet and an outer shell outlet arranged opposite each other along the diameter direction. Two spring plates 17 are provided inside the outer shell. The middle of the spring plates is S-shaped and the two end supports 16 are bent and attached to the inner wall of the outer shell, so that an S-shaped channel is formed between the two spring plates, connecting the outer shell inlet and the outer shell outlet. The pull wire 11 passes through and is tightened in the S-shaped channel.

[0053] Thus, see Figure 2 The pull wire runs through and is taut within an S-shaped channel formed by two spring plates. Within the channel, the pull wire forms an S-shape with a bending angle smaller than the channel itself. The pull wire and the spring plates on either side form two points of contact, creating force. When the pull wire is taut, the S-shapes of the two spring plates deform, generating a force that interacts with the pull wire. Thus, when the wall structure cools (due to thermal expansion and contraction), causing the insulation board material to shrink and the distance between the inner and outer fixing meshes to shorten, the pull wire can loosen due to the deformation of the spring plates, allowing it to tighten again. Conversely, when the wall structure heats, causing the insulation board material to expand and the distance between the inner and outer fixing meshes to increase, the deformation of the two spring plates can extend the effective length of the pull wire, achieving passive adaptive adjustment and consistently ensuring the tight fixation of the insulation board. Meanwhile, the unique structural design of the spring sheet allows its S-shaped shape to deform and provide deformation output when initially subjected to tension pressure on one side of the S-shaped channel. When the pressure increases, the two ends of the spring sheet are squeezed together in opposite directions, further increasing the deformation output. This achieves a dual deformation output effect and greatly improves the adjustable range of the adjustment device.

[0054] The pull wire 11 is also equipped with an active adjustment device, which includes a cylindrical protective shell 18 arranged along the length of the pull wire. The protective shell has elastic skins 19 at both ends. The protective shell has multiple segments of shape memory alloy 20 with a tortuous structure arranged along the length in the middle of the protective shell. The shape memory alloy segments are connected to form a gradually tortuous whole with a gradually increasing deformation temperature (from -10℃ to 45℃). Each shape memory alloy segment can flatten and elongate when it reaches the deformation temperature. The pull wire can be movably passed through the elastic skin and connected to both ends of the shape memory alloy.

[0055] In this way, when the wall temperature changes between hot and cold, as the temperature gradually rises, each segment of shape memory alloy can gradually flatten and elongate with the increase in temperature, thereby extending the effective length of the pull wire so that it can follow the thermal expansion of the wall material; similarly, when the temperature drops, the pull wire can tighten with the contraction of the wall, realizing active adaptive adjustment and always ensuring the tension and fixation effect of the insulation board.

[0056] The outer end of the pull wire 11 is inclined downward.

[0057] This extended length of the guy wire facilitates the installation of the adjustment device and the achievement of its adjustment effect. Simultaneously, the guy wire provides an upward tensile force to the external fixing mesh, which can share some of the weight of the cement mortar and interior layer. Since the cement mortar and insulation layer are bonded together, reducing the gravitational force can better mitigate the risk of interlayer bond failure.

[0058] The insulated wall structure is constructed using the following steps: First, make a fixed frame, inner fixed net and outer fixed net of the corresponding height according to the distance between the upper and lower floor slabs. Complete the welding between the fixed frame and the inner fixed net. Complete the connection between the inner fixed net and the pull line at the preset position. The passive adjustment device and / or active adjustment device are pre-connected to the pull line. b. Complete the installation of the fixing frame and the inner fixing mesh, so that the outer side of the fixing frame is attached to the inner side of the wall, and fix the upper and lower ends of the fixing frame to the upper and lower floor slabs through the mesh holes of the inner fixing mesh using threaded parts; c. Apply cement mortar to the wall through the mesh of the internal fixing mesh. The cement mortar should completely fill and cover the fixing frame until it is flush with the internal fixing mesh, ensuring no air bubbles or gaps, and avoiding the wires being covered by cement mortar to form an inner cement mortar layer. d. Lay the pre-cut insulation boards (bonded) on the outside of the inner cement mortar layer, so that the pull wires set along the vertical row are exactly between the adjacent insulation boards. Pull the outer end of the pull wires out of the outside of the insulation board, and lay the outer fixing net on the outside of the insulation board. Complete the connection between the outer end of the pull wires and the outer fixing net, and press the insulation board tightly to fix it. e. Use gap filler to fill the gaps that may exist between adjacent insulation boards through the mesh of the external fixing mesh. Then apply cement mortar to the outside of the insulation board so that it enters the mesh of the external fixing mesh and completely covers the external fixing mesh. Smooth it to form an external cement mortar layer. After the exterior cement mortar layer has cured, the interior layer is then applied to complete the construction.

[0059] In this way, you can easily and quickly complete the construction of each material layer throughout the entire construction process, ensuring the realization of the functions of each part of the wall structure.
