Description

Technical Field

[0001] The invention relates to an energy-saving wall structure for the exterior protection of a frame structure building and a construction method thereof. Background Art

[0002] The exterior wall systems of frame-structured buildings typically utilize ALC slats for on-site masonry, followed by the application of internal and external insulation layers using a bonding and anchoring method. This results in low construction efficiency, a messy and untidy site, and high labor requirements, lacking the characteristics of industrialized construction. External wall systems typically consider increasing insulation thickness and implementing thermal bridge prevention measures to achieve higher energy efficiency requirements. Furthermore, internal insulation systems fail to address thermal bridges in beams and columns, and thus fail to meet energy efficiency standards. With many provinces and cities nationwide gradually banning the bonding and anchoring method for external insulation, the continued use of ALC slats for on-site masonry presents a situation where there is no alternative insulation method. Furthermore, due to the inherent material properties of ALC slats, cracking and water seepage remain unresolved. Therefore, there is an urgent need for an efficient exterior wall insulation method for frame-structured buildings that meets current energy efficiency requirements while effectively addressing cracking and water seepage issues with ALC slats.

[0056] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.

[0057] Example 1

[0058] like Figure 1As shown, this embodiment discloses an energy-saving wall structure for the exterior enclosure of a frame structure building, which includes an insulation layer 1, a waterproof vapor barrier layer 2, ALC strips 3 and connectors. The insulation layer 1 is connected to the outer side of the frame structure 10 by dry construction, the waterproof vapor barrier layer 2 is arranged on the inner side of the insulation layer 1, and the ALC strips 3 are connected to the frame structure 10 through connectors so that there is a waterproof vapor barrier layer 2 between the outer side of the ALC strips 3 and the insulation layer 1.

[0059] Using a dry construction method, the insulation layer 1 is first installed, connected to the exterior of the frame structure 10. A waterproof vapor barrier layer 2 is then placed in between, followed by the internal ALC panels 3. The ALC panels 3 are then installed and connected to the frame structure 10 using connectors to form the base wall, providing high strength and ease of installation. Furthermore, the waterproof vapor barrier layer 2 is positioned between the insulation layer 1 and the ALC panels 3, effectively preventing cracking and water seepage issues that can occur with the ALC panels 3 due to their material properties. This significantly improves the safety and stability of the energy-saving wall construction surrounding the frame structure.

[0060] By installing the insulation layer 1 first, the outer insulation layer 1 can be leveled first, effectively improving the flatness and verticality of the facade, thus eliminating the need for plastering. This not only effectively reduces building loads but also effectively avoids the risk of the plastering layer falling off due to an overly thick plastering layer. Furthermore, construction efficiency is significantly improved compared to traditional post-application construction methods.

[0061] The insulation layer 1 can be made of a Class A fireproof insulation material. Preferably, the insulation layer 1 is a Class A fireproof insulation material that is a composite of organic and inorganic materials. The insulation performance of this composite Class A fireproof insulation material ensures that, for insulation materials of the same thickness, the strength meets the requirements of relevant product standards and the fireproof performance reaches Class A2, eliminating the need for additional inorganic sheet materials to enhance strength and fireproof performance.

[0062] The material of the thermal insulation layer 1 can be silicon graphene thermal insulation material, which effectively ensures the thermal insulation performance and fireproof performance of the energy-saving wall structure of the frame structure building exterior, and greatly improves the safety and stability of the energy-saving wall structure of the frame structure building exterior.

[0063] The waterproof vapor barrier 2 can be a flexible waterproof cushion or a waterproof vapor barrier membrane. The waterproof vapor barrier 2 can also include a flexible waterproof cushion and / or a waterproof vapor barrier membrane. The flexible waterproof cushion and / or waterproof vapor barrier membrane ensures that the waterproof vapor barrier 2 has excellent waterproof and vapor-permeable properties, thereby protecting the ALC slats 3 and effectively preventing cracking and water seepage, which are common problems with the material of the ALC slats 3.

[0064] In this embodiment, the energy-saving wall structure for the exterior of a frame-structured building further includes a plurality of connecting components 4, one end of each of which is connected to the frame structure 10, and the other end of each of which is connected to the end of the insulation layer 1. The insulation layer 1 is positioned on the exterior side of the frame structure 10, and the upper and lower ends of the insulation layer 1 are directly connected to the frame structure 10 via the connecting components 4, thereby achieving installation of the insulation layer 1 and the frame structure 10. The direct connection of the insulation layer 1 to the exterior side of the frame structure 10 via the connecting components 4 provides high installation strength and facilitates installation and connection.

[0065] At least one reinforcement component 11 is pre-installed within the insulation layer 1. By placing this reinforcement component 11 within the insulation layer 1, the structural strength of the insulation layer 1 is effectively enhanced, improving the safety and stability of the energy-saving wall structure surrounding the frame structure building. The reinforcement component 11 can be a metal reinforcement mesh and / or a hollow metal square tube. The connecting sleeve 61 can be connected to the reinforcement component 11. The number of reinforcement components 11 is not limited.

[0066] The energy-saving wall structure for the exterior enclosure of a frame-structured building also includes a through-fixture 6, which comprises a connecting sleeve 61 and a connecting screw 62. The connecting sleeve 61 is pre-buried within the insulation layer 1. One end of the connecting screw 62 is connected to the connecting sleeve 61, while the other end of the connecting screw 62 passes through the waterproof vapor barrier layer 2 and connects to the ALC slats 3. The connecting sleeve 61 is pre-buried within the insulation layer 1 and connected to the insulation layer 1. A hole is drilled in the ALC slats 3 at the location corresponding to the connecting sleeve 61. The connecting screw 62 passes through the hole in the ALC slats 3 and the waterproof vapor barrier layer 2 before connecting to the connecting sleeve 61 within the insulation layer 1. The connecting screw 62 is also connected to the ALC slats 3, thereby connecting the insulation layer 1, the waterproof vapor barrier layer 2, and the ALC slats 3, further strengthening the connection between the layers of the energy-saving wall structure for the exterior enclosure of the frame-structured building. Furthermore, the connecting sleeve 61 and the connecting screw 62 are threaded, making installation and connection very convenient.

[0067] In this embodiment, the energy-saving wall structure of the frame structure building exterior enclosure further includes a plaster layer 7, which is connected to the outer side surface of the insulation layer 1 and / or the inner side surface of the ALC strips 3. The plaster layer 7 can protect the insulation layer 1 and / or the ALC strips 3, thereby improving the safety and stability of the energy-saving wall structure of the frame structure building exterior enclosure. Among them, the plaster layer 7 includes anti-cracking mortar and alkali-resistant glass fiber mesh cloth, the anti-cracking mortar is connected to the outer side surface of the insulation layer 1 and / or the inner side surface of the ALC strips 3, and the alkali-resistant glass fiber mesh cloth is arranged in the anti-cracking mortar. The anti-cracking mortar is used for leveling and protection, and the alkali-resistant glass fiber mesh arranged in the anti-cracking mortar can enhance the overall structural firmness of the plaster layer 7.

[0068] The energy-saving wall structure for the frame-structured building exterior also includes a bracket 8, to which the insulation layer 1 is connected. Bracket 8 rests against the end surface of the insulation layer 1 and provides a force to the layer, thereby supporting and suspending the layer 1. This provides a secure structural connection, further enhancing the fall-prevention safety of the insulation layer 1 and facilitating construction. Bracket 8 includes upward and / or downward protrusions that engage with the end of the insulation layer 1, further strengthening the connection between bracket 8 and the insulation layer 1.

[0069] This embodiment also discloses a construction method for an energy-saving wall structure for the exterior enclosure of a frame structure building. The construction method for the energy-saving wall structure for the exterior enclosure of a frame structure building is used to produce the above-mentioned energy-saving wall structure for the exterior enclosure of a frame structure building and install it on a frame structure 10. The construction method for the energy-saving wall structure for the exterior enclosure of a frame structure building includes the following steps: S1, hoisting and erecting the insulation layer 1, and connecting the insulation layer 1 to the outer side of the frame structure 10, wherein the waterproof vapor barrier layer 2 is arranged on the inner side of the insulation layer 1; S2, laying ALC strips 3 on the inner side of the insulation layer 1, and connecting the ALC strips 3 to the frame structure 10 through connectors, so that there is a waterproof vapor barrier layer 2 between the outer side of the ALC strips 3 and the inner side of the insulation layer 1.

[0070] Using a dry construction method, the insulation layer 1 is first erected and installed on the exterior of the frame structure 10, and the waterproof vapor barrier 2 is placed on the interior of the insulation layer 1. The ALC panels 3 are then installed and connected to the frame structure 10 via connectors to form the base wall. This ensures that the waterproof vapor barrier 2 is positioned between the insulation layer 1 and the ALC panels 3, effectively resolving the issues of cracking and water seepage that can easily occur with the ALC panels 3 due to their material properties. It also effectively improves the flatness and verticality of the facade, eliminating the need for plastering and leveling. This not only effectively reduces building loads but also mitigates the risk of the plaster screed peeling off due to an overly thick layer. Furthermore, construction efficiency is significantly improved compared to traditional post-application methods.

[0071] Step S1 specifically includes the following steps: S13, hoisting and erecting the insulation layer 1, and setting up temporary fixing measures to temporarily fix the insulation layer 1; S14, directly connecting the insulation layer 1 to the outer side of the frame structure 10 via the connecting member 4. In this embodiment, the insulation layer 1 is directly connected to the outer side of the frame structure 10 via the connecting member 4, which has high construction efficiency and high strength.

[0072] Before hoisting and installing the insulation layer 1, the waterproof vapor barrier 2 can be installed on the inner side of the insulation layer 1. After hoisting and installing the insulation layer 1, the waterproof vapor barrier 2 can also be installed on the inner side of the insulation layer 1. The waterproof vapor barrier 2 can be installed on the inner side of the insulation layer 1 before or after the insulation layer 1 is installed, making installation and connection very convenient.

[0073] Step S2 specifically includes the following steps: S21, drilling a hole in the ALC strip board 3 at a position corresponding to the connecting sleeve 61, so that the connecting screw 62 passes through the hole on the ALC strip board 3 and is connected to the connecting sleeve 61; S22, laying the ALC strip board 3 and sealing the joints of the ALC strip board 3; S23, sealing the hole in the ALC strip board 3.

[0074] After the insulation layer 1 and the waterproof vapor barrier layer 2 are installed and fixed, the ALC strips 3 will be installed and connected. The ALC strips 3 are directly connected to the frame structure 10 through the connecting parts, and are connected to the insulation layer 1 through the connecting screws 62, thereby strengthening the firmness of the connection between the layers of the energy-saving wall structure of the frame structure building exterior enclosure, and greatly improving the safety and stability of the energy-saving wall structure of the frame structure building exterior enclosure.

[0075] After step S2, the following step is also included: S3, plastering the outer side and the inner side. The plastering has a protective effect on the outer side and the inner side, and has high safety and stability.

[0076] Example 2

[0077] like Figure 2 、 Figure 3 and Figure 4 As shown, the energy-saving wall structure and construction method of the frame-structured building exterior enclosure in Example 2 are not repeated in the same manner as in Example 1; only the differences will be described. The energy-saving wall structure of the frame-structured building exterior enclosure in Example 1 does not include metal keels. In Example 2, the energy-saving wall structure also includes metal keels 5, which are connected to the frame structure 10. The inner side of the insulation layer 1 is connected to the metal keels 5 via connecting components 4.

[0078] The metal keel 5 will first be installed on the frame structure 10, and then the insulation layer 1 will be connected to the metal keel 5 through the connecting component 4, so that the insulation layer 1 is installed on the outer side of the frame structure 10, connecting the insulation layer 1 to the metal keel 5, greatly enhancing the connection strength of the insulation layer 1, effectively avoiding the falling off of the insulation layer 1, and greatly improving the safety and stability of the energy-saving wall structure of the frame structure building exterior.

[0079] The connecting component 4 includes at least one anchor plate 41 and at least one anchor rod 42. The anchor plate 41 abuts the outer side of the insulation layer 1. One end of the anchor rod 42 is connected to the anchor plate 41, while the other end of the anchor rod 42 passes through the insulation layer 1 and is connected to the metal keel 5. The connecting component 4 is pressed against the outer side of the insulation layer 1 by the anchor plate 41, and connected to the metal keel 5 by the anchor rod 42. This tightly presses the insulation layer 1 between the anchor plate 41 and the metal keel 5, further strengthening the connection between the insulation layer 1 and the metal keel 5 and effectively preventing the insulation layer 1 from falling off. Furthermore, the structure is simple and installation is very convenient. The anchor plate 41 and anchor rod 42 are integrally formed.

[0080] The metal keel 5 comprises a transverse portion 51 and a vertical portion 52, which are perpendicularly connected to each other. The transverse portion 51 abuts and connects to the inner side of the insulation layer 1, while the vertical portion 52 extends toward the ALC panels 3 and embeds into the joint between two adjacent ALC panels 3. Two connecting components 4 penetrate the insulation layer 1 and connect to the ends of the transverse portion 51, respectively, providing a strong connection. Simultaneously, multiple ALC panels 3 are spliced ​​and installed within the frame structure 10 to form the base wall. The vertical portion 52 embeds into the joint between two adjacent ALC panels 3, effectively sealing the joint.

[0081] In this second embodiment, there is only one transverse portion 51 and one vertical portion 52, and the end of the vertical portion 52 is connected to the middle of the transverse portion 51 facing the ALC strip 3, resulting in a "T"-shaped cross-section of the metal keel 5. Of course, in other embodiments, the end of the vertical portion 52 can also be connected to the end of the transverse portion 51, resulting in an "L"-shaped cross-section between the transverse portion 51 and the vertical portion 52. The number of transverse portions 51 and the number of vertical portions 52 can each be two, with the two transverse portions 51 and the two vertical portions 52 each forming two "L"-shaped connection structures. The vertical portions 52 in the two "L"-shaped connection structures will both be embedded in the seam between two adjacent ALC strips 3.

[0082] In the construction method of the energy-saving wall structure for the exterior enclosure of a frame structure building of this embodiment 2, step S1 specifically includes the following steps: S11, connecting the metal keel 5 to the frame structure 10. S12, hoisting and erecting the insulation layer 1, and connecting the inner side of the insulation layer 1 to the metal keel 5 via the connecting component 4. The metal keel 5 is first installed on the frame structure 10, and then the insulation layer 1 is erected and installed to be connected to the metal keel 5, so that the insulation layer 1 is installed on the frame structure 10 via the metal keel 5, effectively preventing the insulation layer 1 from falling off, and greatly improving the safety and stability of the energy-saving wall structure for the exterior enclosure of the frame structure building.

[0083] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
