Description

Technical Field

[0001] This invention relates to the field of building exterior curtain wall construction technology, and more specifically, to a composite energy-saving aluminum panel curtain wall connection node installation structure. Background Technology

[0002] In the field of energy-saving building materials, composite energy-saving aluminum panel curtain walls serve as the core external envelope structure. Although their production relies on specialized equipment to achieve standardization, the key to whether the inherent energy-saving potential of the material can be fully realized in the final building lies in the matching connection structure adopted in the installation process. This structure is the final bridge that determines whether the high performance of the production end can be transformed into actual engineering efficiency.

[0003] Currently, curtain wall connection technology is mainly evolving around two dimensions: ease of installation and foundation fixation. The mainstream technical solutions can be summarized into three categories: first, traditional bolt through-connection, which achieves rigid fixation through openings in the panel surface; second, pressure block or snap-fit ​​surface-mounted connection, which provides external constraint at the edge of the panel and partially avoids perforation of the panel surface; and third, back bolt connection with micro-adjustment function, which allows for limited adjustment of the installation plane. In addition, to improve construction efficiency, rapid installation structures using principles such as plug-in and rotating snap-fit ​​have also appeared on the market.

[0004] However, during long-term service, the aluminum panel curtain wall will experience complex and uneven thermal expansion and contraction due to changes in the angle of solar radiation and uneven heating of the facade. When the existing connection nodes cannot effectively guide and release these deformations, continuous stress concentration and fatigue accumulation will form inside the nodes. The direct consequence is that the panel surface will be wavy and the sealant will crack after repeated stretching. Ultimately, this will not only damage the appearance and waterproof performance, but also fundamentally endanger the long-term safety and durability of the curtain wall system.

[0005] Therefore, this application proposes a composite energy-saving aluminum panel curtain wall connection node installation structure to solve the above problems. Summary of the Invention

[0006] Technical problem to be solved: In view of the problems existing in the prior art, the purpose of this invention is to provide a composite energy-saving aluminum panel curtain wall connection node installation structure, which solves the problem that when aluminum panel curtain walls are in long-term service, uneven thermal expansion and contraction caused by irradiation and uneven heating will cause existing nodes to be unable to release deformation, which will lead to stress concentration, panel deformation and glue cracking, endangering the safety and durability of the curtain wall.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a composite energy-saving aluminum panel curtain wall connection node installation structure, including vertical keels and two horizontal keels installed in parallel between the two vertical keels. A single panel curtain wall is provided at the front of the vertical keel; T-shaped mounting nodes are provided at the four corners of the back of the single panel curtain wall, and multiple locking nodes are installed parallel to each other at equal intervals on the upper and lower sides of the back of the single panel curtain wall, which together with the single panel curtain wall form a fixed assembly reference structure; locking platforms are installed at the upper and lower parts of the front end of the vertical keel, and thermal compensation components are provided in the locking platforms; auxiliary mounting components are provided on the horizontal keels; the thermal compensation components include: a T-shaped groove opened in the middle of the locking platform and abutment plates sliding on the left and right sides inside the T-shaped groove; T-shaped mounting nodes are slidably mounted in the T-shaped groove, and the two sides of the front end of the T-shaped mounting nodes abut against the rear end faces of the two abutment plates; a contact pressure plate layer is installed on the rear end face of the abutment plates.

[0008] In a new embodiment, the locking platform is provided with a pressure triggering component, which includes a built-in groove, a spring post, and a friction plunger; the locking platform has built-in grooves on both the left and right sides of its front end, and the built-in grooves are located on the left and right sides of the T-shaped groove; a spring post slides through the rear wall of the built-in groove, and the rear end of the spring post is fixedly connected to the front end of the corresponding abutment plate located in the T-shaped groove; a friction plunger is installed at the front end of the spring post.

[0009] In a new embodiment, a friction bushing is provided around the outer periphery of the friction plunger; an inner liner ring is fixedly installed on the inner wall of the built-in plunger groove; the outer wall of the friction bushing and the inner wall of the inner liner ring slide in fit to form a friction pair.

[0010] In a new embodiment, a sealing cap is installed at the front end of the built-in column groove, and an adjusting bolt is threadedly connected to the middle of the sealing cap, with the end of the adjusting bolt corresponding to the front end of the friction plunger.

[0011] In a new embodiment, a top cover is detachably installed on the top of the locking platform, and a limiting protrusion is installed in the middle of the bottom surface of the top cover; a limiting groove is opened at the top of the T-shaped fitting node, the limiting protrusion extends into the limiting groove, and the limiting groove can slide relative to the limiting protrusion, so that the T-shaped fitting node can move horizontally while being restricted vertically.

[0012] In a new embodiment, the auxiliary mounting component includes: a horizontal long plate, fixedly installed on the front end face of the horizontal keel; a locking frame plate, installed on the front end of the horizontal long plate; several node holes, provided and opened on the front of the locking frame plate, the positions of the node holes corresponding to the locking nodes on the back of the single-panel curtain wall; and a mounting plate, which is vertically installed on the opposite inner sides of the two horizontal long plates for supporting and installing the insulation board.

[0013] In a new embodiment, rotating rods are rotatably installed at the four corners of the back of the single-panel curtain wall, and the other end of the rotating rods is rotatably connected to the front end of the T-shaped fitting node.

[0014] In a new embodiment, the locking frame plate is provided with a locking point assembly, which includes: an outer frame shell installed at the top of the locking frame plate; an electromagnet installed on the top wall of the outer frame shell; a movable magnetic locking plate slidably installed in the middle of the locking frame plate and located below the electromagnet; a slot formed in the movable magnetic locking plate; and a groove formed at the rear of the top of each locking node. When the electromagnet is energized, the movable magnetic locking plate is attracted and moved upward, in an unlocked state, allowing the locking node to be inserted or removed. When the electromagnet is de-energized, the movable magnetic locking plate falls under the action of gravity, in a locked state, at which time the slot engages with the groove of the locking node.

[0015] Beneficial effects: Compared with the prior art, the advantages of this invention are: 1. This application addresses the problem of internal stress concentration caused by non-uniform deformation of aluminum panel curtain walls under temperature changes. By allowing the connection nodes to slide smoothly and directionally within a certain range, the destructive thermal stress that the material cannot bear is converted into controllable mechanical displacement and released. This avoids the problems of permanent wave deformation of the panel surface, repeated stretching and cracking of the sealant joint, and fatigue damage of the connectors that are easily caused by traditional rigid connection methods, thereby improving the safety and durability of the curtain wall during long-term service.

[0016] 2. By setting up thermal compensation components, T-shaped grooves are used to guide the T-shaped mounting nodes to slide horizontally. The combination of limiting protrusions and limiting grooves prevents the nodes from falling off vertically. The contact plates that directly contact the two front sides of the T-shaped mounting nodes and the contact pressure plate layer at the rear end form a reliable pressure transmission and contact interface. This ensures that the deformation force of the curtain wall panel can be smoothly transmitted through this contact interface when it expands and contracts with heat. The deformation direction is precisely guided and the sliding is smooth. At the same time, it fundamentally eliminates the risk of nodes falling off due to wind pressure or vibration.

[0017] 3. By setting up a pressure trigger component, the thermal compensation sliding function is made controllable. It provides a continuous elastic clamping force to the contact plate through the spring column, ensuring that the contact pressure plate layer at the front end of the contact plate and the T-shaped fitting node always maintain a tight contact, laying the foundation for force transmission and sliding triggering. At the same time, the friction pair formed by the friction bushing and the inner lining ring provides stable damping for the sliding process, making the sliding smooth and avoiding impact. In addition, combined with the adjusting bolt, the maximum allowable sliding amount of the friction plunger is controlled to prevent over-displacement damage. This mechanism enables the curtain wall to remain stable at room temperature, slide smoothly under large thermal stress, and obtain reliable limit protection in extreme cases.

[0018] 4. By setting up auxiliary mounting components, the installation base of the insulation layer and the hanging point of the curtain wall are combined, simplifying the construction process, avoiding the problem of overlapping processes, and improving the overall insulation continuity. At the same time, the locking components integrated on the auxiliary mounting components use electromagnets to magnetically attract the moving magnetic plate to rise, and gravity to drop it after it is no longer magnetically attracted, so that the slot on it engages or disengages with the groove on the locking node, realizing the engagement and unlocking of the locking node on the single panel curtain wall, which facilitates the independent installation and later maintenance and replacement of the single panel curtain wall.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] This application provides a composite energy-saving aluminum panel curtain wall connection node installation structure, which solves the problem that during long-term service of aluminum panel curtain walls, uneven thermal expansion and contraction caused by irradiation and uneven heating leads to the inability of existing nodes to release deformation, resulting in stress concentration, panel deformation, and sealant cracking, which endangers the safety and durability of the curtain wall. In use, by allowing the connection nodes to slide smoothly in a directional direction, the internal thermal stress of the curtain wall caused by temperature changes is converted into controllable mechanical displacement for release, effectively avoiding the problems of panel deformation and sealant cracking that are easily caused by traditional rigid connections, thereby improving the long-term safety and durability of the curtain wall.

[0034] The technical solutions in this application are intended to solve the above-mentioned technical problems, and the overall approach is as follows.

[0035] Example 1, please refer to Figures 1-12This application provides a composite energy-saving aluminum panel curtain wall connection node installation structure, including vertical keel 1 and two horizontal keels 2 installed in parallel between the two vertical keels 1. A single panel curtain wall 3 is provided at the front of the vertical keel 1. T-shaped mounting nodes 32 are provided at the four corners of the back of the single panel curtain wall 3. Multiple locking nodes 33 are installed at equal intervals on the upper and lower sides of the back of the single panel curtain wall 3. The two and the single panel curtain wall 3 form a fixed assembly reference structure. Locking platforms 4 are installed at the upper and lower parts of the front end of the vertical keel 1. A heat and cold compensation component 5 is provided in the locking platform 4. An auxiliary mounting component 6 is provided on the horizontal keel 2. The heat and cold compensation component 5 includes: a T-shaped groove 51 opened in the middle of the locking platform 4 and abutment plates 52 sliding in the left and right sides of the T-shaped groove 51. The T-shaped mounting nodes 32 are slidably mounted in the T-shaped groove 51, and the two sides of the front end of the T-shaped mounting nodes 32 abut against the rear end faces of the two abutment plates 52. A contact pressure plate layer 53 is installed on the rear end face of the abutment plates 52.

[0036] Furthermore, rotating rod arms 31 are rotatably installed at the four corners of the back of the single-panel curtain wall 3, and the other end of the rotating rod arm 31 is rotatably connected to the front end of the T-shaped fitting node 32.

[0037] In a preferred embodiment of this solution, this application addresses the problem of internal stress concentration caused by non-uniform deformation of aluminum panel curtain walls under temperature changes. By allowing the connection nodes to slide smoothly and directionally within a certain range, the destructive thermal stress that the material cannot bear is converted into controllable mechanical displacement for release. This avoids the problems of permanent wave deformation of the panel surface, repeated stretching and cracking of the sealant joint, and fatigue damage of the connectors that are easily caused by traditional rigid connection methods, thereby improving the safety and durability of the curtain wall during long-term service.

[0038] Specifically, the installation process for the connection node installation structure of this composite energy-saving aluminum panel curtain wall is as follows: First, vertically fix the vertical keel 1 to the main building structure, calibrate the verticality and tighten it. Then, install the two horizontal keels 2 in parallel between the two vertical keels 1, adjust the level and fix it to form a stable rectangular keel frame foundation, which serves as the load-bearing frame for the installation of all subsequent components. Next, install the auxiliary mounting components 6 and locking platforms 4 on the fixed horizontal keels 2 and vertical keels 1 respectively (it should be noted that the top cap 41 is not installed on the top of the locking platform 4 at this stage). Second, the single-panel curtain wall 3 is hoisted to the front of the keel frame using hoisting equipment. The position is slowly adjusted so that the T-shaped mounting node 32 connected to the rear of the single-panel curtain wall 3 via the rotating arm 31 is aligned with the T-shaped groove 51 in the locking platform 4. The T-shaped mounting node 32 is manually slid into the T-shaped groove 51. The two front sides of the T-shaped mounting node 32 will make close contact with the contact pressure plate layer 53 on the rear side of the two contact plates 52 in the T-shaped groove 51. Then, the top cover 41 is installed to the top of the locking platform 4 and tightened so that the limiting protrusion 42 on its bottom surface extends into the limiting slide groove 34 of the T-shaped mounting node 32. This structure allows the T-shaped mounting node 32 to slide horizontally, but prevents it from falling out vertically, forming a safety limit. After the above operations are completed, the operator pushes the single-panel curtain wall 3 inward (i.e., towards the building). Due to the rotational connection between the two ends of the rotating arm 31 and the single-panel curtain wall 3 and the T-shaped mounting node 32, this thrust will drive the single-panel curtain wall 3 to generate a composite displacement of inward translation and slight height change with the rotating arm 31 as the moving link, thereby reaching its final installation position. During this process, the locking node 33 on the back of the single-panel curtain wall 3 moves with the panel body of the single-panel curtain wall 3 and inserts into the preset node hole 63 on the locking frame plate 62. Before the locking node 33 is inserted, the movable locking magnetic plate 83 in the locking frame plate 62 is driven to rise by the electromagnet 82, so that the slot 84 on it... Move to a higher position to make way for the entry of the locking node 33. After the locking node 33 is fully in place, the electromagnet 82 is de-energized, and the movable magnetic locking plate 83 falls under the action of gravity. Its slot 84 then engages in the groove 331 of the locking node 33, realizing the horizontal locking of the single panel curtain wall 3. Combined with the vertical locking of the locking platform 4 and the T-shaped mounting node 32, the overall assembly of the single panel curtain wall 3 is completed. Finally, the tightness and sealing integrity of each connection part must be fully checked to ensure that the installation is qualified. Scenario 1: When the single-panel curtain wall 3 expands due to increased temperature from sunlight, the expansion force is transmitted to the T-shaped mounting node 32 through the rotating arm 31, causing the T-shaped mounting node 32 to slide forward within the T-shaped groove 51. The sliding of the T-shaped mounting node 32 transmits force to the abutment plate 52, which is in contact with its front end, driving the abutment plate 52 to slide synchronously within the T-shaped groove 51. The sliding of the abutment plate 52 causes the spring column 72 and friction plunger 73 connected to it to move forward within the built-in column groove 71 until the front end of the friction plunger 73 slides to the adjusting bolt. The T-shaped mounting node 32 and the contact plate 52 move outward synchronously at the position defined by 75 and then stop moving. At this time, the relative displacement generated by the two in the T-shaped groove 51 (the movement gap of the T-shaped mounting node 32 also appears at the rear of the T-shaped groove 51) provides stress release space for thermal expansion. This sliding process is essentially to convert the concentrated stress that cannot be released due to the rigid fixation of traditional nodes into a controlled and stable mechanical displacement for release, thereby effectively preventing the wave deformation of the single-panel curtain wall 3 panel surface and the cracking of the sealant joint. It is important to note that whether the T-shaped fitting node 32 can drive the contact plate 52 to move depends on whether the expansion force exceeds the adjustable friction resistance threshold set by the pressure trigger component 7, that is, it depends on the maximum static friction force provided by the friction pair formed by the friction bushing 731 and the inner lining ring 711. When the thermal expansion force does not exceed the above-mentioned preset friction resistance threshold, the static friction force provided by the friction pair will lock the entire mechanism in place, the curtain wall panel will remain stable, with only a small amount of elastic deformation and no macroscopic sliding. Meanwhile, by adjusting the depth of screwing in the bolt 75, the limit position of the friction plunger 73 sliding forward can be precisely set, thereby limiting the maximum sliding stroke of the entire thermal compensation mechanism and providing the final safe displacement control for the thermal expansion of the curtain wall to adapt to the safety standards and requirements of different projects. Scenario 2: When the single-panel curtain wall 3 undergoes cold shrinkage deformation due to temperature drop, it generates a horizontal inward shrinkage tendency. This shrinkage force is transmitted through the rotating arm 31, causing the T-shaped mounting node 32 to move inward along the T-shaped groove 51. At the same time, the spring column 72, which is stretched during thermal expansion, releases its stored elastic recoil potential energy, generating a reverse reset elastic force that drives the contact plate 52 to push the T-shaped mounting node 32 back to the rear of the T-shaped groove 51. During this reset process, the friction pair formed by the friction plunger 73 and the inner liner ring 711 continuously provides sliding friction damping. This damping force can slow down the reset speed and prevent the components from rebounding quickly and causing collision impact. At the same time, its synergistic effect with the spring reset force can ensure that the T-shaped fitting node 32 stably returns to the initial preset position, preventing displacement accumulation or loosening due to multiple cycles, and ensuring the long-term stability of the connection. In addition, the limiting protrusions 42 on the top cover 41 and the T-shaped fitting node 32 cooperate with the limiting slide groove 34 to provide vertical guidance and limitation for the front and back sliding of the T-shaped fitting node 32 during thermal expansion and contraction, prevent any vertical deviation, and ensure that the thermal expansion and contraction movement is strictly carried out in the horizontal direction. Scenario 3: Under normal or conventional temperature fluctuations, excluding the effects of drastic thermal expansion and contraction, the single-panel curtain wall 3 remains in a stable locked state, ensuring the effective performance of energy-saving and thermal insulation. The lateral locking is achieved by the locking point component 8 on the auxiliary mounting component 6, effectively resisting the lateral shear force in the curtain wall plane; the snap-fit ​​of the T-shaped mounting node 32 and the locking platform 4 ensures the vertical locking of the curtain wall, ensuring that the single-panel curtain wall 3 will not experience unexpected displacement or shaking under the action of external forces such as conventional wind pressure. Third, when the single-panel curtain wall 3 needs to be inspected, firstly, the electromagnet 82 of the locking point assembly 8 is energized. The magnetic force generated by the electromagnet 82 will attract the movable locking magnetic plate 83 upward, causing its slot 84 to disengage from the groove 331 of the locking node 33, thereby releasing the horizontal mechanical lock at the bottom of the curtain wall panel. Subsequently, the operator can use the rotatable characteristics of the rotating arm 31 to slide the single-panel curtain wall 3 out to the outside. Then, the top cover 41 on the locking platform 4 is removed, so that the T-shaped mounting node 32 on its back slides completely out of the T-shaped groove 51 of the locking platform 4, thereby safely removing the entire single-panel curtain wall 3. After the inspection is completed, secondary assembly can be carried out according to the aforementioned installation process. All standardized connection nodes can be quickly and accurately aligned, ensuring restoration efficiency and quality.

[0039] In this embodiment, please refer to Figures 7-9 As shown, the locking platform 4 is equipped with a pressure triggering component 7, which includes a built-in groove 71, a spring post 72, and a friction plunger 73. The locking platform 4 has built-in grooves 71 on both the left and right sides of its front end, and the built-in grooves 71 are located on the left and right sides of the T-shaped groove 51. The spring post 72 slides through the rear wall of the built-in groove 71, and the rear end of the spring post 72 is fixedly connected to the front end of the corresponding abutment plate 52 located in the T-shaped groove 51. The friction plunger 73 is installed at the front end of the spring post 72.

[0040] In a preferred embodiment of this solution, a pressure triggering assembly 7, consisting of an internal column groove 71, a spring column 72, and a friction plunger 73, is fixedly connected to the front end of the contact plate 52. This structure manages and releases the thermal stress of the curtain wall. The spring column 72 continuously applies pressure to the contact plate 52 through elasticity, ensuring close contact between the contact plate 52 and the T-shaped fitting node 32. At the same time, a friction pair is formed between the friction plunger 73 and the inner wall of the internal column groove 71, providing controllable frictional resistance for the horizontal sliding of the contact plate 52 and the T-shaped fitting node 32. The combined effect of these two factors allows the internal stress of the node of the single-panel curtain wall 3 to be converted into a smooth and controllable micro-displacement by overcoming the frictional resistance and compressing the spring when it expands and contracts with heat. This results in gaps in the installation space of the curtain wall node, effectively releasing the stress and avoiding deformation of the panel or damage to the connection parts caused by stress concentration.

[0041] Further, please refer to Figures 7-9 As shown, a friction bushing 731 is fitted around the outer periphery of the friction plunger 73; an inner liner ring 711 is fixedly installed on the inner wall of the built-in plunger groove 71; the outer wall of the friction bushing 731 and the inner wall of the inner liner ring 711 slide together to form a friction pair.

[0042] In a preferred embodiment of this solution, a friction bushing 731 is fitted around the outer periphery of the friction plunger 73, and an inner liner ring 711 is fixedly installed on the inner wall of the built-in groove 71, so that the two slide together to form a friction pair. The pairing of the friction bushing 731 and the inner liner ring 711 forms a sliding surface with stable interface characteristics and controllable friction coefficient. This not only provides smooth sliding friction damping and ensures that the thermal stress release process is uniform and controllable, but also effectively protects the core components, the friction plunger 73 and the body of the built-in groove 71, by concentrating sliding wear on the replaceable friction bushing 731, thereby improving the durability and long-term operational reliability of the entire pressure triggering assembly 7.

[0043] Furthermore, please refer to Figure 6 As shown, a sealing cap 74 is installed at the front end of the built-in column groove 71, and an adjusting bolt 75 is threadedly connected to the middle of the sealing cap 74. The end of the adjusting bolt 75 corresponds to the front end of the friction plunger 73.

[0044] In the preferred embodiment of this solution, by setting the adjusting bolt 75, the end cap 74 first seals the front end of the internal column groove 71, providing a stable working environment and axial positioning basis for the internal spring column 72 and friction plunger 73, preventing dust intrusion or component dislodgement; secondly, the threaded connection of the adjusting bolt 75 constitutes a mechanical limiting and adjusting structure. By turning the adjusting bolt 75, the axial position of its end in the internal column groove 71 can be changed, thereby directly limiting the limit stroke of the friction plunger 73 sliding forward, thereby controlling the maximum allowable release of thermal expansion, providing the final safe displacement control for the friction plunger 73, and realizing external adjustment and safety setting without disassembly; It is important to note that during actual installation and commissioning, a certain difference in adjustment depth is permissible between the left and right adjusting bolts 75. This is because the pressure triggering components 7 on both sides operate independently, each providing effective elastic clamping and frictional damping to their corresponding contact plates 52. Furthermore, when the single-panel curtain wall 3 undergoes thermal expansion, the driving force on the T-shaped fitting node 32 is a unified force, enabling coordinated responses from both sides. Therefore, even if there is a slight difference in adjustment between the two adjusting bolts 75, it will only cause a minor asynchrony in the sliding stop time on both sides when thermal expansion reaches its limit. However, this does not prevent the curtain wall panel from sliding normally under thermal stress to release internal forces, nor does it affect its reliable limit stop after reaching the set stroke.

[0045] In this embodiment, please refer to Figure 6 and Figure 8As shown, a top cover 41 is detachably installed on the top of the locking platform 4, and a limiting protrusion 42 is installed in the middle of the bottom surface of the top cover 41; a limiting groove 34 is opened at the top of the T-shaped fitting node 32, the limiting protrusion 42 extends into the limiting groove 34, and the limiting groove 34 can slide relative to the limiting protrusion 42, so that the T-shaped fitting node 32 can move horizontally while being restricted vertically.

[0046] In the preferred embodiment of this solution, a detachable top cover 41 is provided, with a limiting protrusion 42 on its bottom surface. At the same time, a limiting groove 34 is opened at the top of the T-shaped fitting node 32 to cooperate with it. The limiting protrusion 42 extends into the limiting groove 34, which constitutes vertical limiting and horizontal guidance for the T-shaped fitting node 32. This prevents the risk of the T-shaped fitting node 32 from vertically detaching from the T-shaped groove 51 when subjected to wind load or vibration, greatly improving the reliability and safety of the connection. At the same time, the limiting groove 34 can slide freely along the limiting protrusion 42, ensuring that the horizontal thermal expansion and contraction displacement of the T-shaped fitting node 32 is not hindered in any way, so that the stress release function can be realized.

[0047] In this embodiment, please refer to Figures 10-12 As shown, the auxiliary mounting component 6 includes: a horizontal long plate 61, which is fixedly installed on the front end face of the horizontal keel 2; a locking frame plate 62, which is installed on the front end of the horizontal long plate 61; a number of node holes 63, which are provided and opened on the front part of the locking frame plate 62, and the position of the node holes 63 corresponds to the locking node 33 on the back of the single panel curtain wall 3; and a mounting plate 64, which is vertically installed on the opposite inner sides of the two horizontal long plates 61 and is used to support and install the insulation board.

[0048] In the preferred embodiment of this solution, by setting up horizontal long plate 61, locking frame plate 62, node hole 63 and hanging plate 64, the upper and lower hanging plates 64 form a natural installation groove between the horizontal long plate 61, which can directly and neatly support the insulation board. The installation process of the insulation layer is organically integrated into the assembly process of the curtain wall keel frame, avoiding the process intersection, spatial conflict and cold bridge problems caused by the separation of insulation and curtain wall structure operations in traditional construction, and improving the degree of construction integration. Meanwhile, the node holes 63 on the locking frame plate 62 correspond precisely to the locking nodes 33 on the back of the single-panel curtain wall 3. During installation, they serve as back guides and support points, ensuring that each single-panel curtain wall 3 can quickly and accurately reach the predetermined plane position, laying the foundation for the subsequent connection of the top nodes, and effectively improving installation efficiency and accuracy. Secondly, the auxiliary mounting component 6 works in conjunction with the locking component 8 to provide a clear and operable decoupling interface for the individual disassembly and maintenance of the single-panel curtain wall 3, which greatly facilitates the maintenance work throughout the entire life cycle of the building.

[0049] In this embodiment, please refer to Figure 11As shown, the locking frame plate 62 is provided with a locking point assembly 8, which includes: an outer frame shell 81, installed at the top of the locking frame plate 62; an electromagnet 82, installed on the top wall of the outer frame shell 81; a movable magnetic locking plate 83, slidably installed in the middle of the locking frame plate 62 and located below the electromagnet 82; a slot 84, formed in the movable magnetic locking plate 83; and grooves 331 are formed at the rear of the top of each locking node 33. When the electromagnet 82 is energized, the movable magnetic locking plate 83 is attracted and moved upward, in an unlocked state, allowing the locking node 33 to be inserted or pulled out. When the electromagnet 82 is de-energized, the movable magnetic locking plate 83 falls under the action of gravity, in a locked state, at which time the slot 84 is engaged in the groove 331 of the locking node 33.

[0050] In the preferred embodiment of this solution, a locking point assembly 8 is constructed, consisting of an outer frame shell 81, an electromagnet 82, a movable magnetic locking plate 83, and a slot 84. This assembly cooperates with the groove 331 on the locking node 33. By energizing and de-energizing the electromagnet 82, the lifting and lowering of the movable magnetic locking plate 83 can be directly controlled, thereby driving the slot 84 to engage and disengage from the groove 331. This replaces the traditional manual tightening of bolts, making the locking and unlocking operations at the bottom of the curtain wall more time-saving and labor-saving. At the same time, when the locking point assembly 8 is de-energized, the movable magnetic locking plate 83 automatically falls and locks under the action of gravity. Its mechanical engagement method provides stable shear resistance, ensuring a firm and reliable connection. It also eliminates the need for continuous power supply to the electromagnet 82, requiring only power during maintenance or replacement, thus improving energy efficiency.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
