Description

Technical Field

[0001] This invention relates to the field of building energy conservation technology, and in particular to a thermally broken connection structure, a prefabricated enclosure system, and its installation method. Background Technology

[0002] Prefabricated buildings, with their advantages of high construction efficiency, energy conservation and environmental protection, and standardized components, have become the mainstream direction of modern building development and are widely used in various engineering scenarios such as residential and public buildings. However, the building envelope of prefabricated buildings is susceptible to the effects of differences in the thermal properties of materials, defects in structural design, and construction processes, which can create heat conduction channels within the structure and thus generate thermal bridging effects.

[0003] Existing technologies often employ prefabricated components with integrated insulation, effectively mitigating thermal bridging issues caused by gaps between components. However, the installation and fixing of prefabricated building envelopes generally rely on rigid components such as metal anchors and embedded connectors. These metal materials have high thermal conductivity and penetrate the insulation layer, making them prone to forming point-like concentrated thermal bridges under the influence of indoor and outdoor temperature differences. Such thermal bridges not only increase building heating and cooling energy consumption and reduce building energy efficiency, but also cause problems such as condensation, dampness, and mold growth on the walls within the connecting areas. Furthermore, long-term damp environments accelerate the aging of insulation materials and the corrosion of metal components, weakening the connection strength and structural stability of the building envelope, ultimately reducing the overall durability and quality of use of the building.

[0004] Therefore, there is an urgent need for a thermally insulated connection structure, a prefabricated enclosure system, and its installation method to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a thermally broken connection structure, a prefabricated enclosure system and its installation method, which cuts off the heat conduction path, destroys the conditions for the formation of point thermal bridges, reduces the energy loss of the building, and improves the overall thermal insulation performance of the assembled building.

[0006] To achieve this objective, the present invention adopts the following technical solution: In a first aspect, a thermally insulated connection structure is provided. The enclosure structure includes an insulation layer and a concrete layer. The thermally insulated connection structure is used to connect the insulation layer and the concrete layer, including: The thermal insulation component includes an inner thermal insulation sleeve and an outer thermal insulation sleeve. The outer thermal insulation sleeve is sealed and penetrates the thermal insulation layer. The inner thermal insulation sleeve is disposed in the inner cavity of the outer thermal insulation sleeve. A thermal insulation space is formed between the outer wall of the inner thermal insulation sleeve and the inner wall of the outer thermal insulation sleeve. The thermal insulation space is filled with thermal insulation gas. The connecting body, which is sealed through the inner heat insulation sleeve, includes a first metal connecting part, a second metal connecting part, and a heat-insulating connecting part. One end of the first metal connecting part can be anchored to the concrete layer, and the other end is detachably connected to one end of the heat-insulating connecting part. The other end of the heat-insulating connecting part is detachably connected to one end of the second metal connecting part. The heat-insulating connecting part is located in the inner cavity of the inner heat insulation sleeve and is configured to block the transfer of heat between the first metal connecting part and the second metal connecting part.

[0007] Optionally, the enclosure structure also includes an enclosure layer disposed on the side of the insulation layer away from the concrete layer, and the thermal break connection structure also includes a thermal break sleeve disposed on the enclosure layer, with the end of the second metal connection portion away from the thermal break connection portion passing through the thermal break sleeve.

[0008] Optionally, the thermal break connection structure also includes a thermal insulation pad sandwiched between the end face of the first metal connection and the concrete layer.

[0009] Optionally, the thermal break connection structure also includes a heat insulation cover that is sealed to the end of the second metal connection portion away from the thermal break connection portion. The heat insulation cover is placed over the end of the second metal connection portion and is sealed to the enclosure structure.

[0010] Optionally, the thermal break connection structure also includes thermal insulation filler, and a sealed filling space is formed between the thermal insulation cover and the second metal connection part, with the thermal insulation filler filling the filling space.

[0011] Optionally, the thermal break connection structure also includes a first sealing filler and a fireproof filler. The first metal connection is sealed to the concrete layer through the first sealing filler, and the fireproof filler is filled between the first metal connection and the concrete layer.

[0012] Optionally, the thermal break connection structure also includes a second sealing filler and a thermal insulation filler. The outer thermal insulation sleeve is sealed to the thermal insulation layer through the second sealing filler, and the thermal insulation filler is filled between the outer wall of the outer thermal insulation sleeve and the thermal insulation layer.

[0013] Optionally, both the first metal connecting part and the second metal connecting part are provided with a screw part, and the heat-insulating connecting part is provided with a threaded hole that is threaded to the screw part.

[0014] Secondly, a prefabricated enclosure system is provided, including an enclosure structure and a thermally broken connection structure as described in the first aspect. The enclosure structure includes a layered concrete layer and an insulation layer, and the insulation layer is connected to the concrete layer through the thermally broken connection structure.

[0015] Thirdly, a method for installing a prefabricated enclosure system is provided, applicable to prefabricated enclosure systems as described in the second aspect, comprising the following steps: S1.

[0023] Example 1 like Figures 1 to 4As shown, this embodiment provides a thermally broken connection structure that cuts off the heat conduction path, disrupts the formation conditions of point thermal bridges, reduces building energy loss, and improves the overall thermal insulation performance of the assembled building.

[0024] See Figure 1 and Figure 2 The enclosure structure 10 includes an insulation layer 11 and a concrete layer 12. The thermally insulated connection structure connects the insulation layer 11 and the concrete layer 12, and includes a thermal insulation component 100 and a connecting body 200. The thermal insulation component 100 includes an inner thermal insulation sleeve 110 and an outer thermal insulation sleeve 120. The outer thermal insulation sleeve 120 is sealed through the insulation layer 11, and the inner thermal insulation sleeve 110 is disposed within the inner cavity of the outer thermal insulation sleeve 120. A thermal insulation space 130 is formed between the outer wall of the inner thermal insulation sleeve 110 and the inner wall of the outer thermal insulation sleeve 120, and the thermal insulation space 130 is filled with thermal insulation gas. The connecting body 200... The sealing passes through the inner insulation sleeve 110. The connecting body 200 includes a first metal connecting part 210, a second metal connecting part 220, and a heat-insulating connecting part 230. One end of the first metal connecting part 210 can be anchored to the concrete layer 12, and the other end is detachably connected to one end of the heat-insulating connecting part 230. The other end of the heat-insulating connecting part 230 is detachably connected to one end of the second metal connecting part 220. The heat-insulating connecting part 230 is located in the inner cavity of the inner insulation sleeve 110 and is configured to block the transfer of heat between the first metal connecting part 210 and the second metal connecting part 220.

[0025] The thermally insulated connection structure provided in this embodiment forms a two-stage thermal insulation layer between the connecting body 200 and the insulation layer 11 with the inner thermal insulation sleeve 110 and the outer thermal insulation sleeve 120. This significantly enhances the effect of cutting off the heat conduction path between the insulation layer 11 and the connecting body 200, which helps to greatly reduce the building's energy loss and improve the overall thermal insulation performance. The thermal insulation gas in the thermal insulation space 130 can further block the transfer of heat, weaken the thermal bridge effect, and further improve the building's thermal insulation performance. The first metal connection part 210 and the second metal connection part 220 can reliably connect the concrete layer 12 and the insulation layer 11. The thermally insulated connection part 230 can effectively block the transfer of heat between the first metal connection part 210 and the second metal connection part 220, blocking the heat conduction path at the connecting body 200, destroying the conditions for the formation of point thermal bridges, further reducing the building's energy loss, and improving the building's thermal insulation performance. In addition, the outer wall of the outer insulation sleeve 120 is sealed to the insulation layer 11, and the inner wall of the inner insulation sleeve 110 is sealed to the connecting body 200. This ensures the sealing effect between the connecting body 200 and the insulation layer 11, prevents condensation, dampness, and mold, extends the service life of the thermal break connection structure, enhances the connection strength and structural stability between the insulation layer 11 and the concrete layer 12, and improves the overall durability and quality of use of the building.

[0026] The thermal break connection structure of this embodiment can be used for various point anchoring scenarios such as exterior wall insulation, prefabricated components, balconies, canopies, curtain walls, and dry hanging in prefabricated buildings.

[0027] For example, compared with the prior art, the thermal break connection structure of this embodiment can reduce heat loss at the connection point by at least 90%, and can reduce the overall heat loss of the building structure by 10% to 25%, fully meeting the usage requirements of ultra-low energy consumption buildings and passive house buildings.

[0028] In this embodiment, the thermally insulated connection portion 230 is made of a material with low thermal conductivity, such as plastic. This design ensures that the thermal conductivity of the thermally insulated connection portion 230 is significantly lower than that of the first metal connection portion 210 and the second metal connection portion 220, making it difficult for heat to pass through the thermally insulated connection portion 230, thereby achieving the purpose of cutting off the heat conduction path of the connecting body 200.

[0029] In this embodiment, the inner insulation sleeve 110 is made of rigid polypropylene, and the outer insulation sleeve 120 is made of a composite foam material of closed-cell polyethylene and polyurethane. Rigid polypropylene has the characteristics of high hardness and low thermal conductivity. Therefore, when in contact with the connecting body 200, the inner insulation sleeve 110 can not only stably withstand the extrusion pressure of the connecting body 200 and maintain structural stability, but also insulate the connecting body 200 from heat conduction, thereby improving the building's thermal insulation performance. The outer insulation sleeve 120 utilizes the closed-cell microporous structure of closed-cell polyethylene to effectively block heat conduction and effectively suppress point thermal bridge effects.

[0030] Optionally, see Figure 1 The enclosure structure 10 also includes an enclosure layer 13 disposed on the side of the insulation layer 11 away from the concrete layer 12. The thermal insulation connection structure also includes a thermal insulation sleeve 300 disposed on the enclosure layer 13, with the end of the second metal connection 220 away from the thermal insulation connection 230 passing through the thermal insulation sleeve 300. The thermal insulation sleeve 300 can cut off the heat conduction path between the second metal connection 220 and the enclosure layer 13, further avoiding heat loss, helping to reduce building energy loss and improve overall thermal insulation performance.

[0031] In this embodiment, when the enclosure structure 10 is an exterior wall, the enclosure layer 13 is located on the side of the insulation layer 11 facing the outside. The setting of the thermal insulation sleeve 300 can effectively block the exchange of heat between the inside and outside, and improve the thermal insulation performance of the building.

[0032] For example, the thermal insulation sleeve 300 may be made of the same material as the outer thermal insulation sleeve 120, or it may be made of other materials with low thermal conductivity.

[0033] Optionally, see Figure 1The thermal break connection structure also includes a thermal insulation pad 400, which is sandwiched between the end face of the first metal connection 210 and the concrete layer 12. The thermal insulation pad 400 not only increases the contact area between the end face of the first metal connection 210 and the concrete layer 12, reducing the local pressure of the first metal connection 210 on the concrete layer 12 and effectively preventing local crushing damage to the concrete, thus ensuring the service life of the concrete layer 12; it also prevents the first metal connection 210 from directly contacting the concrete layer 12, cutting off the heat conduction path between the first metal connection 210 and the concrete layer 12, disrupting the formation conditions of point thermal bridges, and helping to reduce building energy loss.

[0034] In this embodiment, when the enclosure structure 10 is an exterior wall, the concrete layer 12 is located on the side of the insulation layer 11 facing the interior. The setting of the heat insulation pad 400 can effectively block the exchange of heat between the interior and exterior, and improve the building's heat insulation performance.

[0035] For example, the 400 heat insulation pads are made of rigid polyethylene, polyurethane foam, or modified polyolefin. These materials have the characteristics of low thermal conductivity, closed-cell structure, resistance to damp heat, and good mechanical strength, which can effectively isolate heat transfer, block the thermal conduction path between the first metal connection 210 and the concrete, and suppress the end-face thermal bridge effect.

[0036] Optionally, see Figure 1 The thermal break connection structure also includes a thermal insulation cover 500 that is sealed to the end of the second metal connection 220 away from the thermal break connection 230. The thermal insulation cover 500 is placed over the end of the second metal connection 220 and sealed to the enclosure structure 10. External rainwater can easily corrode the second metal connection 220 and enter the interior of the enclosure structure 10 from the connection between the second metal connection 220 and the enclosure structure 10, thus easily forming a low-temperature conduction channel at the second metal connection 220, disrupting the thermal insulation continuity of the enclosure structure 10. The thermal insulation cover 500 can protect the end of the second metal connection 220, reliably blocking rainwater. This not only prevents rainwater from corroding the second metal connection 220 and extending the service life of the second metal connection 220 and the enclosure structure 10, but also prevents the formation of a low-temperature conduction channel at the second metal connection 220, ensuring the thermal insulation continuity of the enclosure structure 10.

[0037] For example, the insulation cover 500 is made of weather-resistant plastic.

[0038] For example, the insulation cover 500 is sealed to the enclosure structure 10 by a sealant.

[0039] Specifically, a sealing ring is fitted on the second metal connection part 220, and a first mounting hole is provided on the insulation cover 500. The second metal connection part 220 extends into the insulation cover 500 through the first mounting hole. The second metal connection part 220 is sealed to the hole wall of the first mounting hole through the sealing ring to prevent rainwater from entering the interior of the enclosure structure 10 from the connection between the second metal connection part 220 and the enclosure structure 10, thus ensuring the continuity of the insulation of the enclosure structure 10.

[0040] For example, the sealing ring is made of a layer of rubber or butyl rubber.

[0041] For example, the second metal connection part 220 is threaded or snapped into the wall of the first mounting hole, so that the second metal connection part 220 can be quickly connected to the insulation cover 500, and the operation is convenient and quick, making it easy to use on the construction site.

[0042] In this embodiment, see Figure 1 The thermal break connection structure also includes thermal insulation filler 510. A sealed filling space is formed between the thermal insulation cover 500 and the second metal connection part 220, and the thermal insulation filler 510 fills the filling space. The thermal insulation filler 510 can further reduce the heat exchange at the end of the second metal connection part 220, improve the overall thermal insulation effect of the thermal insulation cover 500, and ensure the thermal insulation continuity of the enclosure structure 10.

[0043] For example, the thermal insulation filler 510 is made of high-density polyurethane foam or aerogel material. Optionally, see Figure 1 and Figure 3 The thermal break connection structure also includes a first sealing filler 610 and a fireproof filler. The first metal connection 210 is sealed to the concrete layer 12 through the first sealing filler 610, and the fireproof filler is filled between the first metal connection 210 and the concrete layer 12. The first sealing filler 610 ensures a sealed connection between the first metal connection 210 and the concrete layer 12, effectively preventing moisture erosion of the first metal connection 210 and blocking heat transfer at the connection point, thus extending the service life of the thermal break connection structure. The fireproof filler ensures the overall fire resistance of the concrete layer 12, effectively preventing heat damage to the insulation layer 11 and improving the safety of the building structure.

[0044] For example, the first sealing filler 610 is made of airtight tape or sealant. Airtight tape and sealant have good sealing performance, which can seal the gap between the first metal connection 210 and the concrete layer 12, effectively blocking air convection and moisture penetration, and improving the overall thermal insulation performance of the enclosure structure 10.

[0045] For example, fire-retardant filler is fire-retardant putty. Fire-retardant putty has excellent flame-retardant, fire-resistant and sealing properties, and can tightly seal the gap between the first metal connection 210 and the concrete layer 12 to form a reliable fire-resistant isolation layer.

[0046] Optionally, see Figure 1 and Figure 4 The thermal insulation connection structure also includes a second sealing filler 620 and thermal insulation filler. The outer thermal insulation sleeve 120 is sealed to the thermal insulation layer 11 through the second sealing filler 620, and the thermal insulation filler is filled between the outer wall of the outer thermal insulation sleeve 120 and the thermal insulation layer 11. The second sealing filler 620 ensures a sealed connection between the outer thermal insulation sleeve 120 and the thermal insulation layer 11, effectively preventing heat transfer at the connection point. The thermal insulation filler further enhances the thermal insulation effect between the outer thermal insulation sleeve 120 and the thermal insulation layer 11, helping to reduce building energy consumption and meeting the requirements of ultra-low energy consumption buildings and passive house buildings.

[0047] For example, the second sealing filler 620 is made of silicone weather-resistant sealant. Silicone weather-resistant sealant has excellent sealing performance and can effectively seal the gap between the outer thermal insulation sleeve 120 and the thermal insulation layer 11, blocking air convection and water vapor penetration, so that the thermal insulation connection structure has both waterproof sealing and weather-resistant protection performance, significantly improving the overall stability of the enclosure structure 10.

[0048] For example, the insulation filler includes polyurethane foam, which has a closed-cell structure, low thermal conductivity, and can fill gaps, insulate against heat conduction, and weaken cold and thermal bridges in the gaps. In some embodiments, the insulation filler also includes fireproof rock wool, which not only has excellent thermal insulation properties and can block heat transfer, but also effectively inhibits the spread of fire and smoke, improving the fire safety of the enclosure structure 10.

[0049] Optionally, see Figure 2 Both the first metal connecting part 210 and the second metal connecting part 220 are provided with screw parts, and the thermal break connecting part 230 is provided with a threaded hole that mates with the screw parts. This design allows for quick connection between the first metal connecting part 210 and the thermal break connecting part 230, as well as between the second metal connecting part 220 and the thermal break connecting part 230, simply by turning the screw parts. This makes the operation convenient and quick, and easy to use on construction sites.

[0050] For example, both the first metal connection portion 210 and the second metal connection portion 220 are anchor bolts.

[0051] Example 2 like Figures 1 to 4As shown, this embodiment provides a prefabricated enclosure system, including an enclosure structure 10 and a thermally broken connection structure of Embodiment 1. The enclosure structure 10 includes a concrete layer 12 and an insulation layer 11 stacked together. The insulation layer 11 is connected to the concrete layer 12 through the thermally broken connection structure.

[0052] The prefabricated enclosure system provided in this embodiment, by using the thermally broken connection structure of Embodiment 1, can significantly reduce the point-like thermal bridging effect, reduce its overall energy loss, and fully meet the usage requirements of ultra-low energy consumption buildings and passive house buildings.

[0053] In some embodiments, the enclosure structure 10 further includes a finishing layer, and the side of the enclosure layer 13 facing away from the insulation layer 11 and the side of the concrete layer 12 facing away from the insulation layer 11 are both provided with a finishing layer.

[0054] Example 3 like Figure 5 As shown, this embodiment provides an installation method for a prefabricated enclosure system, applicable to the prefabricated enclosure system of Embodiment 2, including the following steps: S1. Install the outer insulation sleeve 120 and the inner insulation sleeve 110 inside the insulation layer 11.

[0055] Specifically, step S1 includes the following steps: S11. Select the appropriate specifications of the connecting body 200 and the thermal insulation component 100 according to the thickness of the insulation layer 11 and the connection load requirements. S12. Determine the installation position of the thermal break connection structure, and open a second installation hole on the insulation layer 11 according to the installation position; S13. Install the outer heat insulation sleeve 120 into the second mounting hole, and install the inner heat insulation sleeve 110 into the outer heat insulation sleeve 120.

[0056] S2. Anchor one end of the first metal connection 210 to the concrete layer 12, and extend the other end into the inner cavity of the inner heat insulation sleeve 110; then, place the heat-breaking connection 230 into the inner cavity of the inner heat insulation sleeve 110 and connect it to the other end of the first metal connection 210; next, place the second metal connection 220 into the inner cavity of the inner heat insulation sleeve 110 and connect it to the heat-breaking connection 230.

[0057] The prefabricated enclosure system installation method of this embodiment provides a standardized construction method for the construction of prefabricated enclosure systems, which can quickly and easily reliably connect the insulation layer 11 and the concrete layer 12, significantly improving the construction efficiency of the prefabricated enclosure system.

[0058] Specifically, before anchoring one end of the first metal connector 210 to the concrete layer 12, the method further includes the following step: placing the heat insulation pad 400 at the end of the first metal connector 210.

[0059] In this embodiment, the following steps are included after step S2: S3. Fill the joint between the first metal connection 210 and the concrete layer 12 with the first sealant 610 and fireproof filler, and fill the joint between the outer heat insulation sleeve 120 and the insulation layer 11 with the second sealant 620 and insulation filler to seal each joint gap, effectively prevent heat exchange at the joint, and reduce building energy consumption.

[0060] S4. Install the insulation cover 500 to the end of the second metal connection 220 away from the heat-insulating connection 230, and fill the filling space with heat-insulating filler 510 to prevent the second metal connection 220 from being corroded, prevent the formation of a low-temperature conduction channel, and ensure the insulation continuity of the enclosure structure 10.

[0061] S5. Use an infrared thermal imaging instrument to detect the thermal bridge effect of the building envelope 10.

Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
