Description

Technical Field

[0001] This utility model belongs to the field of building insulation technology, and in particular relates to a building exterior wall structure. Background Technology

[0002] In the fields of architectural decoration engineering, building materials engineering, and mechanical engineering, external wall insulation systems are a widely used technology and material. They aim to effectively reduce energy consumption and improve the energy efficiency of buildings by adding an insulation layer to the exterior wall surface. Furthermore, this system helps improve the building's appearance and extend its service life. However, over time, early-installed external wall insulation systems have gradually revealed a series of problems, such as cracking, hollowing, and detachment. These problems not only damage the building's appearance and shorten its lifespan but also pose safety hazards.

[0003] To address the aforementioned issues, existing technologies offer various solutions, primarily focusing on repairing or replacing damaged external wall insulation systems. For example, cracks or hollow areas can be treated by grinding, repairing, or replacing the insulation material. To prevent insulation from detaching from the wall, the connection between the insulation layer and the wall can be strengthened by increasing the number of anchors or using a stronger adhesive. In some cases, to completely resolve the problem, the entire external wall insulation system may be replaced. These measures aim to restore the system's integrity and functionality, ensuring the building's safety and aesthetics.

[0004] Such as the self-tapping expansion knot thermal bridging anchor for a building insulation system, application number CN202121776038.X. This anchor includes a thermal bridging bolt, an anchoring kit, and an internal threaded tube with a self-tapping screw coaxially fixed to one end. The thermal bridging bolt consists of an anchoring disc and a threaded rod, made of plastic, possibly mixed with reinforcing fibers or embedded fiber composite materials; the internal threaded tube, external threaded tube, internal / external threaded adapter tube, and self-tapping screw are made of metal; the anchoring kit is made of metal or plastic. The installation method includes attaching an insulation board to the exterior of the base wall, fitting the anchoring kit onto the self-tapping screw and inserting it into a drilled hole, and rotating the anchoring disc of the thermal bridging bolt, causing the self-tapping screw to rotate, causing the anchoring kit to expand or knot and form an anchored connection with the base wall until the anchoring disc is tightly attached to the outer surface of the insulation board. Alternatively, there is a passive building exterior wall cladding thermal bridge anchor with application number CN202322712928.X. This anchor includes a disc, a sleeve, a threaded rod, and a nut. The sleeve is fixedly fitted onto the disc, and the sleeve and disc are integrally injection molded. The inner surface of the sleeve is threaded, matching the threads on the threaded rod. The other end of the threaded rod is threadedly connected to the nut. Existing technology reinforces the insulation layer of building exterior walls with anchors. However, in earthquake-prone areas, some older buildings, even with existing anchors, only undergo conventional reinforcement. During an earthquake, the insulation layer structure is unstable because the anchors, merely attached to the wall, are easily dislodged by the shaking, potentially causing safety accidents. Utility Model Content

[0005] To improve the stability and seismic resistance of the thermal insulation layer structure of building exterior walls, a building exterior wall structure is provided.

[0006] The following technical solution is adopted: A building exterior wall structure includes mechanically self-tapping anchors, which are used to penetrate building mesh fabric and reinforce the insulation layer of the building exterior wall; the mechanically self-tapping anchors include a circular metal anchor plate, a circular metal screw, a circular metal screw expansion head, a circular metal threaded sleeve, and a threaded anti-sway bar; a circular metal screw is fixedly installed in the center of the circular metal anchor plate, the circular metal screw and the circular metal screw expansion head are fixedly connected, and the circular metal screw expansion head is far away from the circular metal anchor plate; the circular metal threaded sleeve is plugged into and pulled out of the circular metal screw; multiple threaded anti-sway bars are fixedly installed on the edge of the circular metal anchor plate; wherein, the distance between two adjacent mechanically self-tapping anchors is not greater than 8000mm.

[0007] Beneficial effects: First, by using self-tapping mechanical anchors to penetrate the building mesh and reinforce the insulation layer, the connection strength between the insulation layer and the wall is enhanced. The fixed connection between the circular metal thread of the self-tapping mechanical anchor and the expansion head, as well as the insertion and extraction connection between the threaded sleeve and the thread, ensures that the anchor is firmly anchored in the wall, effectively preventing the insulation layer from shifting or falling off under external forces. During natural disasters such as earthquakes, the insulation layer is easily damaged by wall swaying. The threaded anti-sway rods in this structure are arranged in a circumferential array around the circular metal thread, which can effectively reduce the swaying of the circular metal thread under external forces such as earthquakes, thereby improving the stability of the insulation layer under extreme conditions such as earthquakes and reducing the risk of safety accidents caused by insulation layer detachment.

[0008] Secondly, the overall design of the self-tapping mechanical anchors makes installation simple and quick. Construction workers only need to pass the anchor through the mesh and screw it into the wall to complete the installation, eliminating the need for complicated procedures and additional tools, greatly improving construction efficiency and shortening the construction cycle. At the same time, the design also facilitates repair or replacement when the insulation layer or anchors are damaged. Because the threaded sleeve and threaded rod are connected by a plug-in joint, damaged parts can be easily disassembled and replaced without requiring large-scale repair or reconstruction of the entire insulation layer, reducing maintenance costs.

[0009] Furthermore, all components of the self-tapping mechanical anchors are made of metal, possessing high strength and durability. They can withstand long-term environmental erosion and external forces, and are not prone to deformation, aging, or damage, thus extending the overall service life of the insulation layer. In addition, this structure effectively prevents cracking and hollowing caused by weak adhesion between the insulation layer and the wall by enhancing the connection stability between them. The integrity of the insulation layer is maintained, and its thermal insulation and waterproofing performance are guaranteed for a long time, further extending its service life.

[0010] Finally, with the stability and integrity of the insulation layer guaranteed, its insulation performance can be fully realized. The reinforcement effect of the mechanical self-tapping anchors ensures a tight bond between the insulation layer and the wall, reducing heat transfer through the wall and effectively lowering the building's energy consumption, thus improving its energy efficiency. Enhanced stability of the insulation layer prevents damage to the building's appearance caused by issues such as insulation layer detachment or cracking. The building's exterior walls maintain a consistently good appearance, improving the overall aesthetics of the building and reducing damage to the building's appearance caused by maintenance and insulation layer replacement.

[0011] Preferably, the threaded anti-sway rods are arranged in a circumferential array around the circular metal screw.

[0012] Beneficial effects: First, the circularly arranged threaded anti-sway bars can evenly distribute external forces, effectively reducing the impact of earthquakes, wind loads, or other external forces on the swaying of mechanical self-tapping anchors, thus significantly enhancing the stability of the insulation layer under dynamic loads. Second, this arrangement makes the connection between the anchors and the insulation layer more secure, further improving the overall crack resistance and deformation resistance of the insulation layer. Furthermore, the circularly arranged threaded anti-sway bars can also provide better guidance during construction, ensuring the verticality and accuracy of anchor installation, thereby improving construction quality and reducing construction difficulty.

[0013] Preferably, the mechanical self-tapping anchor also includes a circular nitrile washer and a square nut on the anchor plate; the circular nitrile washer has a first through hole in the middle, through which it is plugged and pulled to a circular metal screw, and is used to abut against the circular metal anchor plate; the square nut on the anchor plate is fixedly installed on the circular metal anchor plate and faces away from the circular nitrile washer.

[0014] Beneficial Effects: The circular nitrile gasket, with its central through-hole, fits tightly against the circular metal threaded rod. Its excellent elasticity effectively fills the tiny gaps between the self-tapping anchor and the building's exterior wall insulation layer, thereby enhancing the anchor's sealing and waterproofing performance. This prevents moisture from seeping into the wall, avoiding performance degradation of the insulation layer or damage to the wall structure caused by dampness. Simultaneously, the fixed installation of the square nut on the anchor plate further enhances the stability of the circular metal anchor plate, preventing loosening or displacement due to external forces during long-term use, ensuring a firm connection between the self-tapping anchor and the insulation layer. This design not only improves the stability of the insulation layer but also extends the service life of the entire building's exterior wall structure, while reducing later maintenance costs, providing a strong guarantee for the long-term reliable operation of the building insulation system.

[0015] Preferably, the outer diameter of the metal anchor disc threaded sleeve is 10mm, the inner diameter is 8mm, and the length is 20mm; the outer diameter of the metal threaded anchor rod is 6mm, the inner diameter is 4mm, and the length is 30mm; the diameter of the nitrile gasket is 10mm and the thickness is 2mm.

[0016] Beneficial effects: On the one hand, it ensures a tight fit between all components, improving the overall stability and reliability of the anchors, enabling them to withstand greater tensile and shear forces during construction and use, thus effectively reinforcing the insulation layer. On the other hand, standardized dimensions facilitate production and installation, reducing production costs, improving construction efficiency, and also facilitating quality control and subsequent maintenance. Furthermore, a reasonable size ratio optimizes the mechanical properties of the anchors, reducing material waste while meeting functional requirements, achieving a balance between economy and performance.

[0017] Preferably, the building exterior wall structure also includes a monitoring component for monitoring the stability of the mechanical self-tapping anchors; the monitoring component includes multiple monitoring sensors and an alarm, and the monitoring sensors and the alarm are communicatively connected; the building mesh fabric has door and window openings, and the monitoring sensors are fixedly installed on the insulation layer of the building exterior wall through the door and window openings.

[0018] Beneficial effects: First, the addition of monitoring components to the building's exterior wall structure enables real-time monitoring of the stability of the mechanically self-tapping anchors. The monitoring sensors communicate with an alarm system; once anchor loosening or insulation layer abnormalities are detected, an alarm is immediately triggered, alerting maintenance personnel to address the issue promptly. This effectively prevents insulation layer detachment accidents caused by anchor failure, ensuring the safety of building users.

[0019] Secondly, the monitoring sensors are arranged in a square area with reasonable spacing from the edge of the building mesh and between adjacent sensors, ensuring comprehensive and accurate monitoring. This layout effectively covers key areas of the insulation layer, enabling timely detection of potential problems and preventing the escalation of localized hazards.

[0020] Meanwhile, through real-time monitoring and timely early warning, maintenance personnel can accurately locate problems and carry out targeted repairs, avoiding large-scale inspections and maintenance work and significantly reducing maintenance costs. Furthermore, timely detection and handling of potential problems extends the service life of the insulation system and improves the overall performance of the building.

[0021] Finally, the application of monitoring components not only enhances the safety of the insulation system, but also maintains the integrity and performance of the insulation layer through preventative maintenance, further improving the building's energy efficiency and meeting the dual requirements of energy conservation and safety in modern buildings.

[0022] Preferably, the area where the monitoring sensors are arranged is square; the distance between the monitoring sensors and the first edge of the building mesh fabric is not less than 2000mm and not more than 5000mm.

[0023] Beneficial effects: This design ensures that monitoring sensors cover critical areas of the insulation layer, while avoiding blind spots or resource waste caused by sensors being placed too close or too far apart. Appropriate sensor spacing improves monitoring accuracy and reliability, ensuring timely detection of potential problems in the insulation layer, thereby effectively enhancing the overall safety and stability of the building's external wall insulation system, while reducing maintenance costs and safety hazards caused by inaccurate monitoring.

[0024] Preferably, the first distance between two adjacent monitoring sensors is not less than 1000mm and not more than 3000mm.

[0025] Beneficial effects: This ensures that the stability of the anchor bolts is effectively covered by the monitoring sensors. By appropriately controlling the distance between them, the monitoring sensors can more accurately detect minute changes in the anchor bolts during use, such as loosening or deformation, thus issuing timely warning signals. This close-range monitoring layout not only improves the sensitivity and reliability of monitoring but also effectively avoids safety hazards caused by blind spots, further enhancing the overall safety of the building's external wall insulation system and providing strong support for the long-term stable operation of the building.

[0026] Preferably, the distance between the mechanical self-tapping anchor and the monitoring sensor is no more than 3000mm.

[0027] Beneficial effects: This ensures that the monitoring sensors can accurately and in real-time monitor the stability of the anchors. By keeping both within a reasonable close range, the sensors can more sensitively detect even minute displacements or signs of loosening of the anchors, thus issuing timely alarms to remind maintenance personnel to inspect and address the issue. This close-range monitoring layout not only improves the response speed and accuracy of the monitoring system but also further enhances the overall safety of the building's external wall insulation system, effectively preventing safety accidents such as insulation layer detachment caused by anchor failure, and providing a reliable guarantee for the long-term stable operation of the building.

[0028] Beneficial effects of this utility model

[0029] Firstly, self-tapping mechanical anchors, through their unique structural design including a circular metal anchor plate, screw, expansion head, and threaded sleeve, can firmly penetrate the building's mesh fabric and anchor themselves in the wall. This design not only enhances the connection strength between the insulation layer and the wall but also effectively reduces the swaying of the anchors under external forces such as earthquakes through the circumferential array of threaded anti-sway rods. This significantly improves the seismic performance of the insulation layer and reduces the risk of safety accidents caused by earthquakes.

[0030] Secondly, the installation process of mechanical self-tapping anchors is simple and quick, requiring no complicated operations from construction personnel, thus greatly improving construction efficiency. Simultaneously, standardized component dimensions (such as the specific dimensions of the threaded sleeve and screw) ensure a tight fit between components, further enhancing the stability and reliability of the anchors and reducing construction errors.

[0031] Meanwhile, by introducing monitoring components and strategically arranging multiple monitoring sensors within the insulation layer, which are then connected to an alarm system, real-time monitoring of anchor stability is achieved. This proactive monitoring mechanism can promptly detect potential loosening or damage, providing early warnings and enabling preventative measures to be taken, thereby effectively preventing safety incidents such as insulation layer detachment. Furthermore, the rational arrangement of the monitoring sensors (e.g., a square area layout with appropriate distances from edges and between adjacent sensors) ensures comprehensive and accurate monitoring, further enhancing the system's reliability.

[0032] Subsequently, through real-time monitoring and timely early warning, maintenance personnel can accurately locate problems and carry out targeted repairs, avoiding large-scale inspections and maintenance work and significantly reducing maintenance costs. At the same time, timely detection and handling of potential problems extends the service life of the insulation system and improves the overall performance of the building.

[0033] Finally, with the stability and integrity of the insulation layer guaranteed, its insulation performance can be fully realized. The mechanical self-tapping anchors and monitoring components of this invention work together to reduce heat transfer through the wall, thereby effectively reducing building energy consumption and improving energy efficiency. Furthermore, the long-term stable operation of the insulation layer also improves the building's appearance and enhances its overall aesthetics. Attached Figure Description

[0041] Example

[0042] like Figure 1 and 2 As shown, this embodiment provides a building exterior wall structure 8, including a mechanical self-tapping anchor. The novel mechanical self-tapping anchor includes a circular metal anchor plate 1, a square nut 2 on the anchor plate, a circular metal threaded rod 3, a circular nitrile washer 4, a circular metal threaded sleeve 5, a circular metal threaded rod expansion head 6, and a threaded anti-sway rod 7. The outer diameter of the metal anchor plate threaded sleeve is 10mm, the inner diameter is 8mm, and the length is 20mm; the outer diameter of the metal threaded anchor rod is 6mm, the inner diameter is 4mm, and the length is 30mm, with studs at both ends; the nitrile washer has a diameter of 10mm and a thickness of 2mm. In this embodiment, the metal anchor plate threaded sleeve is a stainless steel anchor plate threaded sleeve.

[0043] Install the metal anchor plate threaded sleeve into the external wall insulation system, then insert the metal threaded anchor rod into the metal anchor plate threaded sleeve. Finally, place the nitrile gasket between the metal threaded anchor rod and the metal anchor plate threaded sleeve, ensuring a tight fit. Use an electric screwdriver to tighten the metal threaded anchor rod, ensuring a tight connection with the metal anchor plate threaded sleeve and nitrile gasket.

[0044] Specifically, self-tapping anchors are used to penetrate the building mesh 9 to reinforce the insulation layer of the building's exterior wall 8. The self-tapping anchors include a circular metal anchor plate 1, a circular metal screw 3, a circular metal screw expansion head 6, a circular metal threaded sleeve 5, and threaded anti-sway rods 7. The circular metal screw 3 is fixedly installed in the center of the circular metal anchor plate 1, and the circular metal screw 3 and the circular metal screw expansion head 6 are fixedly connected, with the expansion head 6 located away from the circular metal anchor plate 1. The circular metal threaded sleeve 5 is plugged into and pulled into the circular metal screw 3. Multiple threaded anti-sway rods 7 are fixedly installed on the edge of the circular metal anchor plate 1. The threaded anti-sway rods are arranged in a circumferential array around the circular metal screw 3. The threaded anti-sway rods 7 are spirally inserted into the building mesh 9 to further reinforce the insulation layer of the building's exterior wall 8. The threaded anti-sway rods 7 are arranged in a circumferential array, which can greatly reduce the swaying of the circular metal screws 3 caused by earthquakes and extend the service life of the mechanical self-tapping anchors. At the same time, installation is convenient, efficient, and quick; they simply need to be screwed into the insulation layer of the building's exterior wall 8 along with the circular metal screws 3 and their expansion heads 6. The length ratio of the threaded anti-sway rods 7 to the circular metal screws 3 is 0.2. The mechanical self-tapping anchors also include a circular nitrile washer 4 and a square nut 2 on the anchor plate. The circular nitrile washer 4 has a first through hole in its center, through which it is plugged into and pulled to connect with the circular metal screws 3, and is used to abut against the circular metal anchor plate 1. The square nut 2 on the anchor plate is fixedly installed on the circular metal anchor plate 1, facing away from the circular nitrile washer 4.

[0045] The building exterior wall 8 structure also includes a monitoring component for monitoring the stability of the mechanical self-tapping anchors. The monitoring component includes multiple monitoring sensors 11 and an alarm, with the sensors and alarm communicating with each other. Door and window openings are provided in the building mesh fabric 9, through which the monitoring sensors 11 are fixedly installed on the insulation layer of the building exterior wall 8. The area 10 where the monitoring sensors 11 are arranged is square. The distance 12 between the monitoring sensor 11 and the first edge of the building mesh fabric 9 is not less than 2000 mm and not more than 5000 mm. The first spacing 13 between two adjacent monitoring sensors 11 is not less than 1000 mm and not more than 3000 mm. The distance between the mechanical self-tapping anchors and the monitoring sensors 11 is not more than 3000 mm.

[0046] Beneficial effects of this embodiment

[0047] First, a novel type of mechanical self-tapping anchor was adopted, comprising a metal anchor disc threaded sleeve, a metal threaded anchor rod, and a nitrile washer. This design simplifies the anchor structure, making it easier to install and operate, thereby significantly improving work efficiency, reducing construction costs, and facilitating recycling.

[0048] Meanwhile, the anchor plate is made of stainless steel, which gives it excellent corrosion resistance and tensile strength, ensuring the stability and long service life of the anchor during use.

[0049] Secondly, the threaded anchor rod is made of stainless steel and features a circular threaded design with plum blossom patterns at both ends. This not only enhances the tensile and shear strength of the threaded anchor rod but also ensures the reliability and stability of the anchor connection.

[0050] Then, nitrile round gaskets are used. Due to their excellent elasticity and aging resistance, they can effectively ensure the sealing and waterproof performance of the anchors, thus providing a guarantee for the long-term durability of the external wall insulation structure.

[0051] Furthermore, by installing the metal anchor plate threaded sleeve in the external wall insulation system, then inserting the metal threaded anchor rod, and placing a nitrile gasket between the two, this mechanical self-tapping anchor can effectively solve the common problems of cracking, hollowing, and falling off in external wall insulation structures, thereby improving the safety of the building and extending its service life.

[0052] Finally, when multiple such self-tapping anchors are installed on the external wall insulation structure, they together form a stable anchoring system, further enhancing the stability and reliability of the entire system and providing more comprehensive protection and support for the building.
