Description

Technical Field

[0001] The present invention belongs to the technical field of building envelope structures, and in particular relates to an assembled zero-carbon house building envelope structure. Background Art

[0002] House construction, as an important carrier, is gradually integrating the concept of standards; by adopting green building technology, energy-saving materials and renewable energy, rural houses not only achieve low-carbon emissions, but also improve living comfort; this model injects new vitality into the rural economy and promotes the construction of beautiful and ecologically livable villages.

[0003] Zero-carbon buildings can significantly reduce energy consumption during heating and cooling by optimizing the thermal insulation and airtightness of the building envelope and combining it with an efficient heat recovery and fresh air system. At the same time, by making full use of renewable energy and new energy storage technologies, they can provide buildings with a more comfortable, healthy and sustainable indoor environment while reducing energy usage.

[0004] The enclosure structure is composed of thermal insulation decorative composite panels, anchors, bonding materials and sealing materials. It is placed on the outside of the building's exterior wall and is connected to the base wall by a combination of adhesive bonding and anchor bolts, which provides insulation, protection and decoration for the building.

[0005] Zero-carbon buildings are a new type of sustainable building model; thermal insulation technology is a key technology to improve energy utilization efficiency. In the thermal energy management of building walls, how to effectively block heat transfer, store and release heat energy becomes the key; existing thermal insulation technologies have the following problems: First, traditional insulation materials usually use a single insulation layer or reflective layer, which lacks effective response to thermal expansion and contraction, resulting in insufficient structural stability and prone to cracking or loosening; second, existing insulation structure designs mostly use a single dense structure, lack effective pore design, and have limited insulation performance, which makes it difficult to meet the needs of zero-carbon buildings for efficient insulation and thermal energy management.

[0006] Patent application publication number CN119914039A discloses a low-energy building envelope structure, which is symmetrically arranged with sliding mechanisms on both sides of the beam. The sliding mechanism includes a water tank, and two sliders are symmetrically fixed on both sides of the water tank. The sliders are slidably connected in the corresponding slide grooves; a cleaning mechanism is installed at the bottom of the water tank, and the cleaning mechanism includes a cleaning brush; a scraping mechanism is arranged inside the shell, and the scraping mechanism includes several lifting columns equidistantly installed inside the shell, and a scraper is commonly installed at the bottom of the several lifting columns; it can remove stubborn stains on the glass roof and effectively shovel snow.

[0007] However, the building envelope structure in this patent has the following disadvantages: the envelope structure can only improve light transmittance by removing roof stains, thereby improving energy utilization, but lacks effective cooling measures, which is not conducive to achieving a zero-carbon effect for the house. Summary of the Invention

[0008] The purpose of the present invention is to solve the problems that the enclosure structure in the existing technology lacks effective response to thermal expansion and contraction, which makes the structure prone to loosening or cracking, affecting the overall stability; lacks an efficient heat energy storage and release mechanism, making it difficult to effectively regulate the indoor temperature, and provides an assembled zero-carbon house building enclosure structure.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: See also Figure 1 - Figure 2As shown, an assembled zero-carbon house building envelope structure includes a light steel main structure 2, a phase change layer 201 installed in the interlayer of the light steel main structure 2, and an insulation decorative composite panel 1 installed on the light steel main structure 2. The light steel main structure 2 is assembled into a house main structure; the light steel main structure 2 can be recycled and is a green and environmentally friendly circular building body.

[0028] Fireproof sheets 202 are provided on both sides of the light steel main structure 2. The fireproof sheets 202 are used to encapsulate the phase change layer 201 in the interlayer of the light steel main structure, so that the phase change layer 201 is encapsulated in the interlayer of the light steel main structure 2.

[0029] The light steel main structure 2, the phase change layer 201 installed in the interlayer of the light steel main structure 2, and the thermal insulation decorative composite panel 1 installed on the light steel main structure 2 together form an assembled zero-carbon house building envelope structure.

[0030] The thermal insulation decorative composite panel 1 may be made of a metal facing material or a thin ceramic facing material; the thermal insulation decorative composite panel 1 has certain weather resistance.

[0031] Please refer again Figure 3 - Figure 6 As shown, the light steel main structure 2 is assembled in a rectangular shape or an H-shape, and the interior of the light steel main structure 2 is filled with a phase change layer 201; the phase change layer 201 includes an outer frame 1021, and a cavity 1022 is provided inside the outer frame 1021, and a plurality of capsules 1023 are provided in the cavity 1022; the shape of the capsule 1023 is an elliptical shape or a cylindrical shape.

[0032] A fixing ring 13 is provided at the maximum diameter of the capsule 1023 . A first limiting groove 1302 is formed on the fixing ring 13 . A limiting block 1303 is matched with the first limiting groove 1302 .

[0033] The limiting block 1303 toward the inside of the fixing ring 13 is arc-shaped, and the arc-shaped limiting block 1303 fits the elliptical capsule 1023 better; the limiting block 1303 toward the outside of the fixing ring 13 is provided with a second limiting groove 1304, and a rubber ring 1305 is matched on the second limiting groove 1304.

[0034] The rubber ring 1305 can automatically adjust the position of the limit block 1303 in the first limit groove 1302 according to the size of the capsule 1023, ensuring that the limit block 1303 on the fixing ring 13 accurately fixes the capsule 1023 and fixes the capsule 1023; on the one hand, it fixes the position of the capsule 1023, and on the other hand, it ensures the stability of the capsule 1023.

[0035] The rubber ring 1305 can flexibly adjust the position of the limit block 1303 in the first limit groove 1302 according to the different sizes of the capsule 1023 due to thermal expansion and contraction, thereby achieving precise fixation of the capsule 1023, ensuring the stable position of the capsule 1023 on the fixing ring 13, and can also effectively adapt to the needs of capsules 1023 of different sizes. Through the elastic characteristics of the rubber ring 1305, the limit block 1303 can automatically adapt to the shape of the capsule 1023, provide uniform fixing force, and avoid offset or loosening problems caused by improper fixation.

[0036] The material encapsulated in the capsule 1023 is fatty acid; the capsule 1023 is made of rubber material.

[0037] Capsule 1023 uses a material with high elasticity and recoverability, which can effectively cope with the phenomenon of thermal expansion and contraction under different temperature conditions; when the temperature changes, the elastic material will undergo appropriate deformation according to the environmental conditions, avoiding problems such as structural loosening caused by temperature fluctuations, thereby effectively solving the problems caused by thermal expansion and contraction and improving the stability of the overall structure.

[0038] Under high temperature conditions, solid-liquid phase change materials can absorb a large amount of heat through the phase change process, thereby effectively reducing the ambient temperature inside the house; under low temperature conditions, the material will release the stored heat through the reverse phase change process to maintain the stability of the ambient temperature inside the house; this characteristic makes solid-liquid phase change materials have important application value in zero-carbon houses, and can achieve efficient thermal energy storage and release, improve the energy utilization efficiency of the house, reduce dependence on traditional energy, and facilitate the realization of zero-carbon goals.

[0039] A connecting rod 1301 is provided between adjacent fixing rings 13 , and the connecting rod 1301 is provided on the outside of the fixing ring 13 ; adjacent fixing rings 13 are connected by the connecting rod 1301 .

[0040] Embedded fixing blocks 12 are provided on the inner side walls around the outer frame 1021 . The embedded fixing blocks 12 are arranged corresponding to the positions of the connecting rods 1301 . The connecting rods 1301 close to the inner side walls of the outer frame 1021 are fixedly connected to the embedded fixing blocks 12 .

[0041] The capsules 1023 are arranged in layers uniformly. The capsules 1023 are fixed by fixing rings 13. The connecting rods 1301 connect adjacent fixing rings 13. Pores 1024 are formed between adjacent capsules 1023. The capsules 1023 are evenly arranged to produce multiple pores 1024, thereby forming a bionic porous structure.

[0042] The air filled in the pores 1024 is a poor conductor of heat and can effectively block the transfer of heat. It can significantly improve the thermal insulation performance of the wall, reduce the exchange of indoor and outdoor heat, thereby reducing the energy consumption of the building and facilitating the realization of the zero-carbon goal.

[0043] The bionic porous structure can effectively absorb sound wave energy, reduce the reflection and propagation of noise, significantly improve the sound insulation effect of the building, and provide residents with a quieter and more comfortable indoor environment.

[0044] The bionic porous structure can guide and promote the natural flow of air, optimize the ventilation performance of the building. Good ventilation helps regulate indoor temperature and humidity, reduces dependence on traditional mechanical ventilation systems, further reduces energy consumption, and is more conducive to achieving zero-carbon goals.

[0045] Please refer again Figure 7 - Figure 8 As shown, an adhesive layer 3 is provided on the outer side of the light steel main structure 2 , and the other side of the adhesive layer 3 is fixedly connected to the inner side of the thermal insulation decorative composite panel 1 .

[0046] In this embodiment, when the reflective insulation layer 103 is a metal finishing material, the connection method of the light steel main structure 2 and the thermal insulation decorative composite panel 1 is as follows: A first clamping block 6 and a second clamping block 7 are provided on the upper part of the thermal insulation decorative composite panel 1. The first clamping block 6 is provided on the side close to the light steel main structure 2, and the second clamping block 7 is provided on the side away from the light steel main structure 2. The upper part of the second clamping block 7 is provided with a chamfer; a third notch 10 is provided at the bottom of the second clamping block 7, and the third notch 10 passes through the thermal insulation decorative composite panel 1 horizontally.

[0047] A first slot 8 matching the first block 6 is provided at the bottom of the thermal insulation decorative composite panel 1, and a second slot 9 matching the second block 7 is provided at the bottom of the thermal insulation decorative composite panel 1 away from the light steel main structure 2. An extension plate 11 is provided at the bottom of the second slot 9. The height of the extension plate 11 is greater than the height of the third slot 10, and the extension plate 11 can cover the third slot 10. A special anchor is used at the third slot 10 to connect the thermal insulation decorative composite panel 1 and the light steel main structure 2.

[0048] The upper thermal insulation decorative composite panel 1 is clamped into the first slot 8 of the lower thermal insulation decorative composite panel 1 through the first clamping block 6, and the second clamping block 7 is clamped into the second slot 9 of the lower thermal insulation decorative composite panel 1, and then the thermal insulation decorative composite panel 1 and the light steel main structure 2 are connected at the third slot 10 through a special anchor.

[0049] On the one hand, the extension plate 11 ensures the aesthetics of the exterior wall and provides effective protection for the special anchors. Long-term exposure of the special anchors to the natural environment, especially the erosion of wind and sun, may cause corrosion, aging and other problems in the anchors, thereby affecting their performance and service life. The extension plate 11 covers the special anchors, which not only improves the appearance quality of the entire building, but also significantly extends the service life of the special anchors, thereby improving the durability and safety of the building.

[0050] See also Figure 9 As shown, in this embodiment, when the reflective insulation layer 103 is a thin ceramic facing material, the connection method of the light steel main structure 2 and the thermal insulation decorative composite panel 1 is as follows: A horizontal limiting hole 4 is provided on the upper part of the thermal insulation decorative composite panel 1 away from the side of the light steel main structure 2. The limiting hole 4 is set at 5-8 cm away from the outer wall. An anchor rod 5 is matched in the limiting hole 4. The anchor rod 5 is Z-shaped. One end of the anchor rod 5 is fixedly connected to the light steel main structure 2, and the other end of the anchor rod 5 passes through the limiting hole 4. The anchor rod 5 is fixed to the insulation layer 101 and the reflective insulation layer 103 through a special anchor, thereby realizing the connection between the light steel main structure 2 and the thermal insulation decorative composite panel 1; the setting of the limiting hole 4 not only increases the aesthetics, but also ensures the connection between the light steel main structure 2 and the thermal insulation decorative composite panel 1, thereby increasing stability.

[0051] First, the thermal insulation decorative composite panel 1 is bonded to the light steel main structure 2 with special glue, and then the anchor rod 5 is engaged into the limiting hole 4, and a special anchoring structure is used for fixed connection. It is worth noting that the special anchoring structure is fixed through the insulation layer 101 and the reflective insulation layer 103 to prevent the special anchor from penetrating the capsule 1023 and causing leakage of the capsule 1023.

[0052] In specific implementation, it includes the following steps: Step 1: When filling the phase change layer 201 into the light steel main structure 2, a certain gap is left around the outer frame 1021 to facilitate the connection between the anchor and the light steel main structure 2, and to prevent the anchor from penetrating the capsule 1023 and causing leakage of the capsule 1023.

[0053] Step 2: When the reflective insulation layer 103 is a metal finishing material, the connection method between the light steel main structure 2 and the thermal insulation decorative composite panel 1 is as follows: the thermal insulation decorative composite panel 1 and the light steel main structure 2 are bonded with special glue, and then the upper thermal insulation decorative composite panel 1 is inserted into the first slot 8 of the lower thermal insulation decorative composite panel 1 through the first clamping block 6, and the second clamping block 7 is inserted into the second slot 9 of the lower thermal insulation decorative composite panel 1, and then the thermal insulation decorative composite panel 1 and the light steel main structure 2 are connected at the third slot 10 through a special anchor.

[0054] When the reflective insulation layer 103 is a thin ceramic finishing material, the connection method between the light steel main structure 2 and the thermal insulation decorative composite panel 1 is as follows: the thermal insulation decorative composite panel 1 and the light steel main structure 2 are bonded with special glue, and then the anchor rod 5 is inserted into the limiting hole 4, and a special anchoring structure is used for fixed connection. It is worth noting that the special anchoring structure is fixed through the insulation layer 101 and the reflective insulation layer 103 to avoid the special anchor penetrating the capsule 1023 and causing the capsule 1023 to leak.

[0055] Example 2: The material encapsulated in the capsule 1023 is paraffin wax, and the capsule 1023 is made of silicone material.

[0056] Comparative Example 1: The difference from Example 1 is that the phase change layer 201 is not provided in the high-performance building envelope structure.

[0057] Comparative Example 2: The difference from Example 1 is that the material in the phase change layer 201 is thermal insulation cotton.

[0058] The high-performance building envelope structures of Examples 1-2 and Comparative Examples 1-2 were subjected to performance tests; the strength performance was tested according to the standard GB50189-2015, the heat transfer coefficient performance was tested according to the standard GB / T20311-2006; and the seismic resistance performance was tested according to the standard GB / T50011-2010.

Under high temperature conditions, a large amount of heat can be absorbed through the phase change process, thereby effectively reducing the ambient temperature inside the house; under low temperature conditions, the material will release the stored heat through the reverse phase change process, maintain the stability of the ambient temperature inside the house, and can achieve efficient heat energy storage and release, thereby improving the energy utilization efficiency of the house.
