Description
Technical Field
[0001] This utility model relates to the field of building curtain wall structure technology, and in particular to a windproof reinforcement device for steel-aluminum composite curtain walls of high-rise buildings. Background Technology
[0002] With the development of the modern construction industry, high-rise buildings have become the mainstream form of urban architecture due to their advantages such as high land utilization and concentrated spatial functions. Among them, steel-aluminum composite curtain walls, as the core component of the facade of high-rise buildings, combine the high strength and rigidity of steel with the lightweight and easy processing characteristics of aluminum. They can meet the aesthetic requirements of building facades while taking into account structural load-bearing capacity and energy-saving performance, and are widely used in various super high-rise residential buildings, commercial complexes and public buildings.
[0003] However, due to their height advantage, high-rise buildings are constantly exposed to complex wind environments, facing wind pressure loads far greater than those of mid- and low-rise buildings. Especially during extreme weather events such as typhoons and strong gusts, high-speed airflows generate periodic alternating positive and negative pressures on the curtain wall surface, resulting in uneven stress distribution across the entire curtain wall.
[0004] Existing steel-aluminum composite curtain wall panels are typically connected to the building's main frame via metal hangers, with bolts used for fixing both the hangers to the curtain panels and the hangers to the frame. Under continuous strong winds, the curtain panels experience high-frequency, low-amplitude reciprocating vibrations due to wind pressure fluctuations. This vibration is continuously transmitted to the bolts, causing gaps in the threaded fit between the bolts and connectors, leading to bolt loosening. If this loosening is not addressed promptly, it can result in minor issues such as sealing failure at the panel joints, leading to water seepage, air leakage, and reduced sound insulation; or more serious issues such as failure of the connection between the curtain panel and the hangers, posing a safety hazard of panel detachment and failing to meet the structural safety and functional requirements for long-term use of high-rise building curtain walls. Therefore, a targeted wind-resistant reinforcement device is urgently needed. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a windproof reinforcement device for steel-aluminum composite curtain walls of high-rise buildings that can strengthen the installation bolts of curtain panel hangers, greatly reduce the probability of loosening, and improve the reliability of curtain panel installation.
[0006] This utility model discloses a windproof reinforcement device for steel-aluminum composite curtain walls of high-rise buildings, including angle irons installed on the frame columns, with several hangers bolted to the angle irons, and also including: Locking components are set up one-to-one with the hanging parts; The locking assembly includes a pressure plate, and a pin is vertically arranged in the middle of the pressure plate; The contact surface between the hanger and the angle iron is provided with an insertion hole, and the angle iron is provided with an extension hole coaxial with the insertion hole. The pin slides through the insertion hole and the extension hole from the outside of the hanger and extends into the angle iron. The angle iron is equipped with a support component. Anti-loosening washers are provided between the clamping plate and the mounting nut of the hanger. The number of anti-loosening washers corresponds to the number of mounting nuts of the hanger. The part of the pin located inside the angle iron is provided with external threads. The pin is locked to the support component by the nut. At this time, the anti-loosening washers squeeze the mounting nut of the hanger, and the anti-loosening washers are squeezed out with grooves that fit the mounting nut.
[0007] Furthermore, the support assembly includes two support bars and a support plate. The two support bars are installed on the inner sidewall of the part where the angle iron mounting bracket is located. The two support bars are located on both sides of the pin shaft. The opposite sidewalls of the two support bars are provided with sliding grooves. The two ends of the support plate are slidably inserted into the two sliding grooves respectively. The side of the support plate facing the bracket is provided with a locking hole. The end of the pin shaft with external threads passes through the locking hole and is locked on the support plate by a nut.
[0008] Furthermore, the support plate is configured as an arc plate that bulges outward away from the clamping plate, and the support plate is made of spring steel.
[0009] Furthermore, an auxiliary block is provided on the side of the support plate facing the hanger, and an auxiliary pad is provided on the auxiliary block. The pin is locked to the support plate by a nut. At this time, the auxiliary pad presses against the nut of the mounting bolt of the hanger, and a groove that matches the nut of the mounting bolt is pressed out on the auxiliary pad.
[0010] Furthermore, both the anti-loosening pad and the auxiliary pad are provided with an elastic rubber layer and a metal sheet layer, wherein the metal sheet layer is pressed into contact with the corresponding nut or bolt and creates a groove.
[0011] Furthermore, the metal sheet layer is bonded to the elastic rubber layer, and the metal sheet layer is provided with a number of stabilizing pins, all of which are inserted into the elastic rubber layer.
[0012] Furthermore, the surface of the metal sheet layer that is pressed against the nut or bolt is set as a brushed surface or a knurled surface.
[0013] Furthermore, the clamping plate and the support plate are respectively provided with a first limiting rod and a second limiting rod to limit the compression of the elastic rubber layer.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Based on the dual anti-loosening mechanism of "groove locking + friction", the anti-loosening pad and auxiliary pad form a groove that matches the nut / screw after being squeezed, physically locking and restricting its rotation; at the same time, the brushed / knurled surface of the metal sheet layer enhances the friction with the nut / screw. The dual effect greatly reduces the probability of bolt loosening and makes the anti-loosening effect more reliable. 2. The support components are made of spring steel, whose elastic properties can continuously apply pressure to the locking nut of the pin, ensuring that the pin remains locked for a long time and providing stable force support for the dual anti-loosening mechanism; 3. The anti-loosening pad and auxiliary pad have an "elastic rubber layer + metal sheet layer" structure. The rubber layer ensures a tight fit to form an effective groove, while the metal sheet layer enhances the structural strength and friction. The two work together to strengthen the double anti-loosening effect and extend the service life of the pad. 4. The bidirectional fixing design of "anti-loosening pad + auxiliary pad" provides double anti-loosening for both the nut and bolt, avoiding overall loosening caused by the failure of a single fixing end, and further improving the safety of curtain wall installation; 5. The first and second limit rods precisely limit the amount of compression of the rubber layer, preventing excessive compression that could cause the rubber to lose its elasticity, ensuring the long-term stability of the "groove stuck" shape, and maintaining the continuous effectiveness of the dual anti-loosening mechanism.

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0017] like Figures 1 to 6 As shown, this utility model discloses a windproof reinforcement device for a steel-aluminum composite curtain wall in high-rise buildings, including angle iron 2 installed on the frame column 1, with several hanging parts 3 bolted to the angle iron 2, and also including: Locking components are set one-to-one with hanging parts 3; The locking assembly includes a pressure plate 4, and a pin 5 is vertically arranged in the middle of the pressure plate 4; The contact surface between the hanging piece 3 and the angle iron 2 is provided with an insertion hole, and the angle iron 2 is provided with an extension hole coaxial with the insertion hole. The pin 5 slides through the insertion hole and the extension hole from the outside of the hanging piece 3 and extends into the angle iron 2. An angle iron 2 is provided with a support component. An anti-loosening washer 6 is provided between the clamping plate 4 and the mounting nut of the hanger 3. The number of anti-loosening washer 6 corresponds to the number of mounting nuts of the hanger 3. The part of the pin 5 located inside the angle iron 2 is provided with external thread. The pin 5 is locked to the support component by the nut. At this time, the anti-loosening washer 6 squeezes the mounting nut of the hanger 3, and a groove that matches the mounting nut is squeezed out on the anti-loosening washer 6. In this embodiment, Angle iron 2: connects the frame column 1 and the hanger 3, provides basic support for the installation of the curtain panel, and is the load-bearing carrier of the entire device; Hanger 3: Connects angle iron 2 to the curtain wall panel, transfers the load of the curtain panel to angle iron 2, and provides an installation reference for the locking components; Locking assembly: The clamping plate 4 transmits the locking force through the pin 5, which pushes the anti-loosening pad 6 to squeeze the nut to form a groove; the through structure of the pin 5 provides a positioning basis for the "groove locking", and its locking nut relies on the support assembly for anti-loosening; Anti-loosening pad 6: The core anti-loosening component, which forms a groove that matches the nut when squeezed, physically locking and restricting rotation. The metal sheet layer 12 contacts the nut to enhance friction, achieving dual anti-loosening through "groove + friction". Supported components: core locking components, capable of withstanding 5 locking forces from the pin.
[0018] As a preferred embodiment of the above, the support component includes two support bars 7 and a support plate 8. The two support bars 7 are installed on the inner side wall of the part of the angle iron 2 where the hanging part 3 is installed. The two support bars 7 are located on both sides of the pin 5. The opposite side walls of the two support bars 7 are provided with sliding grooves. The two ends of the support plate 8 are respectively slidably inserted into the two sliding grooves. The surface of the support plate 8 facing the hanging part 3 is provided with a locking hole. The end of the pin 5 with external thread passes through the locking hole and is locked on the support plate 8 by a nut. The support plate 8 is set as an arc plate that protrudes outward in the direction away from the pressure plate 4. The support plate 8 is made of spring steel. In this embodiment, Support bar 7: Fixed to the inside of angle iron 2, it restricts the lateral displacement of support plate 8 through the sliding groove, ensuring that support plate 8 accurately bears the force of pin 5; Support plate 8: Receives the locking force of pin 5 and transmits the force to auxiliary pad 10 to compress the nut to form a groove. At the same time, its spring steel material provides elastic pressure to prevent the nut of pin 5 from loosening. Spring steel material: The core purpose is to continuously apply pressure to the pin 5 nut through elastic deformation, maintaining the long-term locked state of the pin 5; at the same time, the elastic properties can evenly transmit pressure, ensuring that the auxiliary pad 10 is evenly compressed. Outwardly convex arc plate shape: Optimizes the stress structure, avoids the support plate 8 from breaking due to long-term elastic pressure, extends the service life of the support components, and ensures the continuous anti-loosening effect on the pin 5 nut.
[0019] As a preferred embodiment of the above embodiment, an auxiliary block 9 is provided on the side of the support plate 8 facing the hanger 3, and an auxiliary pad 10 is provided on the auxiliary block 9. The pin 5 is locked on the support plate 8 by a nut. At this time, the auxiliary pad 10 presses the nut of the mounting bolt of the hanger 3, and a groove that matches the nut of the mounting bolt is pressed out on the auxiliary pad 10. In this embodiment, Auxiliary block 9: Positioning auxiliary pad 10, to ensure that it is precisely aligned with the bolt and nut, so that the groove formed by extrusion is completely matched with the nut, ensuring the "groove stuck" effect; Auxiliary pad 10: works with anti-loosening pad 6 to achieve bidirectional double anti-loosening, compresses the nut to form a groove, and the metal sheet layer 12 enhances the friction with the nut, while relying on the elastic pressure of the support plate 8 to maintain the compression state.
[0020] As a preferred embodiment of the above, both the anti-loosening pad 6 and the auxiliary pad 10 are provided with an elastic rubber layer 11 and a metal sheet layer 12, wherein the metal sheet layer 12 is pressed into contact with the corresponding nut or bolt and generates a groove. In this embodiment, Elastic rubber layer 11: Ensures that the pad fits tightly with the nut / screw through elastic deformation, provides the necessary deformation space to form a fitting groove, and ensures the effectiveness of "groove locking"; Metal sheet layer 12: It directly contacts the nut / screw, which enhances friction and improves the rigidity of the pad, preventing the rubber layer from being damaged by stress alone and extending the life of the anti-loosening component.
[0021] As a preferred embodiment of the above, the metal sheet layer 12 is bonded to the elastic rubber layer 11, and the metal sheet layer 12 is provided with a plurality of stabilizing pins 13, all of which are inserted into the elastic rubber layer 11. In this embodiment, Stabilizing pin 13: Prevents the metal sheet layer 12 from separating from the elastic rubber layer 11 due to vibration and compression, ensuring the stability of the composite function of the rubber layer and the metal layer, and maintaining the dual anti-loosening effect.
[0022] As a preferred embodiment of the above, the surface of the metal sheet 12 that is pressed against the nut or bolt is a brushed surface or a knurled surface; In this embodiment, Brushed / knurled surface: Increases the friction between the metal sheet layer 12 and the nut / screw, strengthens the friction effect in "groove locking + friction", further restricts the rotation of the nut / screw, and improves the reliability of anti-loosening.
[0023] As a preferred embodiment of the above embodiment, the pressing plate 4 and the support plate 8 are respectively provided with a first limiting rod 14 and a second limiting rod 15 to limit the compression of the elastic rubber layer 11; In this embodiment, First limiting rod 14: limits the compression of the rubber layer of the anti-loosening pad 6, avoids excessive deformation of the rubber and loss of elasticity, ensures the stability of the groove shape of the anti-loosening pad 6, and maintains the "locking" effect on the nut; Second limiting rod 15: limits the compression of the rubber layer of auxiliary pad 10, and similarly ensures the stability of the groove shape of auxiliary pad 10, maintains the "locking" effect on the nut, and ensures that the double anti-loosening mechanism is effective for a long time. When locking the clamping plate 4, the locking process of the clamping plate 4 is completed when the first limiting rod 14 is pressed against the hanging piece 3 and the second limiting rod 15 is pressed against the angle iron 2.
[0024] The working principle of this utility model is as follows: 1. Installation process: First, fix the angle iron 2 to the frame column 1, and use bolts to initially fix the hanging part 3; then insert the pin 5 of the locking component into the hanging part 3 and the angle iron 2, and after extending into the angle iron 2, connect it with the spring steel support plate 8, and finally tighten the nut of the locking pin 5.
[0025] 2. Anti-loosening mechanism: When tightening the fastening nut, the clamping plate 4 compresses the anti-loosening pad 6, causing its metal sheet layer 12 to form a groove that locks the nut in place and prevents loosening through friction. At the same time, the support plate 8 is pulled, and the auxiliary pad 10 compresses the nut to form a groove that locks the nut in place and prevents loosening through friction. This achieves bidirectional "groove + friction" anti-loosening at both ends of the bolt. The elastic deformation of the spring steel support plate 8 will continuously press the nut on the fastening pin 5 to prevent it from loosening and ensure the foundation for anti-loosening. The first limit rod 14 and the second limit rod 15 prevent the anti-loosening pad 6 and the auxiliary pad 10 from being over-compressed and failing, maintaining a long-term anti-loosening effect.
[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
