Description

Technical Field

[0001] This utility model relates to the field of modern industrial building construction technology, specifically to a positioning and connection device for cantilever scaffolding. Background Technology

[0002] Cantilever scaffolding is a scaffolding system that transfers loads to the building structure through rigid cantilever beams. It is suitable for auxiliary scaffolding on construction sites of high-rise buildings and tall structures. To ensure the safety of cantilever scaffolding, construction standards require that its supporting structure must use steel profiles or cantilever trusses, and then steel pipe supports are erected on the supporting structure to form the overall scaffolding structure.

[0003] In existing technologies, when erecting cantilever scaffolding on-site, welding is typically used to fix the supporting structure to the steel pipes. Short reinforcing bars or angle steel slots are welded to the supporting structure to create vertical positioning structures, and then uprights are inserted into these structures to position the scaffolding. However, since the steel sections or cantilever trusses used as supporting structures are usually part of the building structure, the welding, installation, and dismantling processes of the cantilever scaffolding significantly reduce the local bending strength and fatigue life of the supporting structure, posing a safety hazard for the long-term operation of the building. Utility Model Content

[0004] In view of this, the present invention provides a cantilever scaffolding positioning and connection device to solve the problem in the prior art that the mechanical performance of the scaffolding support structure on the building structure is affected after the cantilever scaffolding is installed on the building structure.

[0005] This utility model provides a positioning and connection device for cantilever scaffolding, including:

[0006] The connector has a mating part fixedly installed on one side, which is suitable for connecting with the scaffold body, and a snap-fit ​​part fixedly installed on one end of the connector.

[0007] A locking assembly is mounted on a connector. The locking assembly includes a positioning member with a positioning portion extending parallel to the connector. The positioning member is adapted to rotate about its mounting position on the connector so that the positioning portion has a first state facing the snap-fit ​​member and a second state away from the snap-fit ​​member.

[0008] When installing the cantilever scaffolding positioning and connection device on a cantilever structure, taking an I-beam cantilever structure as an example, the connector is placed at the top of the cantilever structure. One end of the connector engages with the edge of the upper flange of the I-beam cantilever structure, securing one end of the connector. Then, by rotating the positioning component, it faces the engagement component, positioning the component and connector on the upper and lower surfaces of the upper flange of the I-beam cantilever structure, respectively. The other end of the connector is then secured by the locking assembly, thus stably fixing the connector to the I-beam cantilever structure. When setting up the scaffolding, the members on the scaffolding are connected to the mating components on the connector to install the cantilever scaffolding onto the cantilever structure. After use, the scaffolding body is removed from the mating components. Then, the positioning component is rotated to a second state away from the engagement component, unlocking the locking assembly, allowing the connector to be completely removed from the cantilever structure. The cantilever scaffolding positioning and connection device provided in this application, through the cooperation of snap-fit ​​components and locking parts, eliminates the need for welding, cutting, or other operations on the cantilever structure during installation and disassembly. This significantly reduces damage to the cantilever structure during installation and ensures that the mechanical properties of the cantilever structure are not affected during installation and disassembly. Furthermore, the cantilever scaffolding positioning and connection device retains its structural integrity after disassembly, allowing for direct reinstallation at the corresponding position for subsequent reuse. This increases the device's reusability and installation and usage efficiency.

[0009] In one alternative embodiment, the locking assembly further includes a locking member adapted to lock the positioning member and the connector in place.

[0010] Beneficial effects: The locking element is used to fix the relative position between the positioning element and the connecting element, reducing the risk of loosening or tilting during the locking process and improving the structural strength.

[0011] In one optional embodiment, the locking element is a through shaft, which passes through the positioning element and the connecting element in sequence. Both ends of the through shaft are threaded with locking bolts, and the positioning element and the connecting element are located between a pair of locking bolts.

[0012] Beneficial effects: The through shaft and the locking bolts at both ends form a bidirectional clamping, and the positioning part and the connecting part are fixed between a pair of bolts by the symmetrical thread preload, so as to fix the relative position of the connecting part and the locking assembly.

[0013] In one optional embodiment, the positioning member is further provided with a mounting part, which is arranged parallel to the positioning part. An installation gap is provided between the mounting part and the positioning part along a direction perpendicular to the mounting part, and the mounting part and the positioning part are fixedly connected by a connecting part.

[0014] Beneficial effects: By setting an installation gap between the mounting part and the positioning part, the mounting part and the positioning part are spaced apart, so that the mounting part and the positioning part can be engaged on the upper and lower sides of the upper flange of the I-beam cantilever structure. Through the cooperation of the mounting part and the positioning part, one end of the cantilever I-beam is clamped and can be detached.

[0015] In one alternative embodiment, one side of the mounting portion is disposed in contact with the connector, and a first anti-slip portion is provided on the side of the mounting portion in contact with the connector.

[0016] Beneficial effects: The first anti-slip part increases the friction coefficient of the side of the positioning part that contacts the connector, effectively resisting displacement or loosening caused by vibration, impact or lateral load, and ensuring that the connector and the positioning part always keep in close contact.

[0017] In one alternative embodiment, a second anti-slip part is provided at the mounting position of the positioning member on the connector.

[0018] Beneficial effects: The cooperation between the first and second anti-slip parts increases the friction coefficient between the contact surfaces of the positioning part and the connecting part, improves the connection strength between the positioning part and the connecting part, and avoids slippage between the positioning part and the connecting part caused by lateral load.

[0019] In one alternative implementation, the connector is a connecting plate or a connecting frame.

[0020] Beneficial effects: The connecting plate is a planar plate structure, and the connecting frame is a planar frame structure, both of which have high structural strength, are simple to manufacture, and improve work efficiency.

[0021] In one alternative embodiment, the mating component is a mating tube, which is welded and fixed to the positioning component.

[0022] Beneficial effects: Welded connections form a fused metal interface, capable of withstanding greater axial forces, bending moments, and torques. Welding eliminates fretting wear or loosening gaps present in bolted connections, ensuring permanent coaxiality between the mating pipe and the positioning components. During scaffold body installation, the members on the scaffold body are simply inserted into the mating pipe, improving the installation efficiency of the scaffold body.

[0023] In one alternative embodiment, the snap-fit ​​element is a U-shaped hook, and one sidewall of the snap-fit ​​element is fixedly connected to the connector.

[0024] Beneficial effects: The U-shaped opening allows the cantilevered I-beam to slide directly into or be inserted from the side without the need to align the threaded hole or use tools. It is removable, reusable, and highly efficient.

[0025] In one alternative implementation, the connector and the snap-fit ​​are integrally formed.

[0026] Beneficial effects: The one-piece molding structure is simple, reducing the steps of secondary installation of connectors and snap-fit ​​parts. Moreover, the one-piece molding structure can eliminate the connection interface between connectors and snap-fit ​​parts, thereby improving structural strength. Attached Figure Description

[0038] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] Cantilever scaffolding is a temporary support system that transfers loads to the main structure of a building through rigid cantilever beams (such as I-beams, channel steel, or trusses). It is suitable for construction of high-rise buildings, tall structures, or irregularly shaped buildings. Its core feature is that it relies on the building structure itself for load-bearing capacity, without the need for ground support. The support structure must use steel sections or cantilever trusses to ensure sufficient bending stiffness and load-bearing capacity, and be reliably connected to the main structure of the building through pre-embedded anchors, U-bolts, or welding. The uprights of the steel pipe scaffolding must be vertically fixed to the cantilever beams. Traditionally, short steel bars or angle steel are welded together for positioning, and then horizontal bars, scissor braces, and other components are connected with couplers to form a stable frame. Current standards require that all connection nodes must meet the requirements for anti-slip, anti-uplift, and anti-overturning. After the scaffolding is erected, load tests and acceptance tests must be conducted to ensure safety before it can be put into use.

[0040] Traditional welding fixing methods, while simple and direct, have significant drawbacks. The high temperatures involved in welding alter the metallographic structure of the steel, reducing the strength and fatigue life of the cantilever beams and posing a long-term safety hazard to the building structure. Welding quality is highly susceptible to human factors, easily resulting in defects such as incomplete welds and undercuts, leading to the risk of scaffold loosening. Furthermore, welded components are not reusable and require cutting during dismantling, potentially causing secondary damage to the structure. This invention provides a cantilever scaffold positioning and connection device to address the problem in existing technologies where the installation of cantilever scaffolding affects the mechanical properties of the scaffolding support structure within the building structure.

[0041] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0042] According to an embodiment of the present invention, a cantilever scaffold positioning and connection device is provided, comprising: a connector 101, on one side of which a mating part 102 is fixedly installed, the mating part 102 being adapted to engage with the scaffold body, and a snap-fit ​​part 103 being fixedly installed at one end of the connector 101; and a locking assembly, installed on the connector 101, the locking assembly including a positioning part 201, a positioning portion 2011 provided on the positioning part 201, the positioning portion 2011 extending parallel to the connector 101, the positioning part 201 being adapted to rotate about its installation position on the connector 101, so that the positioning portion 2011 has a first state facing the snap-fit ​​part 103 and a second state away from the snap-fit ​​part 103.

[0043] The cantilever scaffolding positioning and connection device is installed on the cantilever support structure of the building structure. In this embodiment, the cantilever structure is an I-beam cantilever structure. The specific implementation process of the installation, use, and dismantling of the cantilever scaffolding positioning and connection device on the I-beam cantilever structure is as follows: First, the construction personnel need to determine the accurate positioning point of the connector 101 according to the scaffolding erection plan, and place the connector 101 horizontally at the predetermined position on the top of the I-beam. The front end of the connector 101 is equipped with a snap-fit ​​103, which contacts the upper and lower sides of the upper flange of the I-beam. Then, the snap-fit ​​103 is used to snap onto one side of the upper flange of the I-beam, which can achieve the initial fixation of the connector 101 without damaging the surface of the steel. The operator then rotates the positioning part 201 at the tail end of the connector 101. During the rotation, the positioning part 201 moves along a predetermined trajectory. When the positioning part 2011 rotates to the first state, it is positioned towards the snap-fit ​​part 103 and snaps into the lower surface of the upper flange of the I-beam. At this time, the main body of the connector 101 and the positioning part 201 form a bidirectional clamping structure, which can be used with external positioning structures such as nuts and bolts for final tightening. During the scaffolding erection stage, the construction workers align the joint at the bottom of the scaffolding upright with the mating part 102 at the upper end of the connector 101 to complete the installation of the scaffolding on the positioning connection device. During dismantling, the scaffolding member connection is first released, then the external positioning structure is loosened, and then the positioning part 201 is rotated to the second state and moved out from the bottom of the upper flange of the I-beam, thereby engaging the lock on one end of the positioning part 201. The cantilever scaffolding positioning connection device provided in this application achieves non-destructive installation and dismantling on cantilever structures through the coordinated cooperation of the snap-fit ​​part 103 and the adjustable locking component. The entire installation process of this device avoids traditional hot work processes such as welding and cutting, which not only eliminates the impact of high temperature on the mechanical properties of the cantilever structure steel, but also allows the components after disassembly to be reused.

[0044] In one embodiment, the connector 101 is a connecting plate or a connecting frame. The connecting plate is a planar plate structure, and the connecting frame is a planar frame structure; both have high structural strength, are simple to manufacture, and improve work efficiency. In this embodiment, to ensure the stability of the fit and fixation between the connector 101 and the upper flange of the I-beam, a connecting plate is selected as the connector 101.

[0045] In one embodiment, the mating part 102 provided on the top surface of the connector 101 is a mating tube, which is welded to the positioning part 201. The welded connection forms a metal fusion interface, which is stronger than bolts or riveting and can withstand greater axial force, bending moment and torque. Welding can eliminate fretting wear or gap loosening that exists in bolted connections, ensuring the permanent coaxiality of the mating tube and the positioning part 201.

[0046] In one embodiment, the snap-fit ​​element 103 is a U-shaped hook, and one sidewall of the snap-fit ​​element 103 is fixedly connected to the connector 101. The U-shaped opening allows the cantilevered I-beam to slide directly into or snap into the side without aligning with the threaded hole or using tools. It is removable, reusable, and highly efficient.

[0047] In this embodiment, to ensure the stability of the connection between the connector 101 and the snap-fit ​​member 103, the connector 101 adopts a U-shaped plate structure, and the connector 101 and the snap-fit ​​member 103 are integrally formed. The integrally formed structure is simple, reduces the secondary installation steps of the connector 101 and the snap-fit ​​member 103, and improves the structural strength.

[0048] In some embodiments, combined with Figure 1 As shown, the locking assembly also includes a locking member 202, which is adapted to lock and fix the positioning member 201 and the connecting member 101. The locking member 202 fixes the relative position between the positioning member 201 and the connecting member 101, reducing the risk of loosening or tilting during the snap-fit ​​process and improving the structural strength.

[0049] As one implementation, the positioning member 201 and the connecting member 101 can be snapped onto the upper and lower end faces of the cantilevered I-beam snap-fit ​​joint, and locked by the locking member 202. The distance between the positioning member 201 and the connecting member 101 is the thickness of the cantilevered I-beam snap-fit ​​joint, and the connecting member 101 and the positioning member 201 tend to move closer together.

[0050] Furthermore, the positioning element 201 can be implemented as a flat plate structure.

[0051] In some embodiments, combined with Figure 1As shown, the locking component 202 is a through shaft that passes through the positioning component 201 and the connecting component 101 in sequence. Both ends of the through shaft are threaded with locking bolts. The positioning component 201 and the connecting component 101 are positioned between a pair of locking bolts. The through shaft and the locking bolts at both ends form a bidirectional clamping force. Symmetrical thread preload fixes the positioning component 201 and the connecting component 101 between the bolts, thus fixing the relative position of the connecting component 101 and the locking assembly. Simultaneously, the through shaft allows the positioning component 201 and the connecting component 101 to freely adjust their positions in the axial direction to adapt to different spacing requirements.

[0052] Furthermore, the positioning component 201 is also provided with a mounting part 2012, which is arranged parallel to the positioning part 2011. A mounting gap is provided between the mounting part 2012 and the positioning part 2011 along a direction perpendicular to the mounting part 2012. The mounting part 2012 and the positioning part 2011 are fixedly connected by a connecting part. The positioning part 2011 is used to cooperate with the through shaft to ensure precise alignment and locking with the connecting component 101. The mounting part 2012 is suitable for clamping the cantilevered I-beam, and the connecting part rigidly connects the two to maintain overall stability. Through the cooperation of the mounting part 2012 and the positioning part 2011, one end of the cantilevered I-beam is clamped and can be detachably adjusted, making it suitable for cantilevered I-beams with different properties.

[0053] As one implementation, the positioning part 201 can be Z-shaped, with the mounting part 2012 and the positioning part 2011 parallel to each other. The two ends of the connecting part are respectively connected to the mounting part 2012 and the positioning part 2011. When locked in the first state, the connecting part and the mounting part 2012 work together on the cantilevered I-beam and cooperate with the snap-fit ​​part 103 to form a snap-fit ​​action, thereby achieving a fixed connection with the cantilevered I-beam.

[0054] As one implementation, the positioning element 201 can be a slot corresponding to the cantilevered I-beam, with the opening of the slot corresponding to the snap-fit ​​point of the cantilevered I-beam.

[0055] In some embodiments, combined with Figure 3 As shown, one side of the mounting part 2012 is in contact with the connector 101, and a first anti-slip part 301 is provided on the side of the mounting part 2012 that is in contact with the connector 101. The first anti-slip part 301 can increase the friction coefficient of the contact surface, effectively resisting displacement or loosening caused by vibration, impact or lateral load, and ensuring that the connector 101 and the mounting part 2012 always remain in close contact.

[0056] Furthermore, a second anti-slip part 302 is provided at the mounting position of the positioning part 201 on the connector 101. The cooperation between the first anti-slip part 301 and the second anti-slip part 302 increases the coefficient of friction between the contact surfaces of the positioning part 201 and the connector 101, improves the connection strength between the positioning part 201 and the connector 101, and avoids slippage between the positioning part 201 and the connector 101 caused by lateral loads.

[0057] As one implementation, the first anti-slip part 301 and the second anti-slip part 302 can also be fitted together by a sawtooth structure meshing with each other, or coated with an anti-slip layer and fitted with an anti-slip pad.

[0058] The specific implementation process of this solution is as follows: Connector 101 is placed on the upper surface of the cantilevered I-beam. Connector 101 is a flat plate structure. First, the snap-fit ​​103 at one end of connector 101 is snapped into the edge of the upper flange of the cantilevered I-beam. Snap-fit ​​103 is a U-shaped slot structure, formed by extending and bending connector 101. The U-shaped slot inside snap-fit ​​103 is suitable for accommodating one side of the edge of the upper flange of the cantilevered I-beam. Then, the positioning member 201 at the other end of connector 101 is operated. Positioning member 201 is a Z-shaped plate, which serves as the upper side plate of the Z-shaped plate of mounting part 2012, tightly attached to connector 101. Through cooperation with bolts, the tightness of the bolts controls the tightness of the connection between mounting part 2012 and connector 101. The positioning component 201 is rotated around the bolt positioning axis until its lower side plate, serving as the positioning part 2011, engages with the connecting component 101 to form a clamping structure that clamps and engages with the upper and lower sides of the edge of the cantilevered I-beam's upper flange. The contact portion between the upper side plate of the Z-shaped plate and the connecting component 101 has a serrated anti-slip structure. After the positioning component 201 is rotated to the first state and locked in place by the locking bolt, the serrated structure on the top surface of the upper side plate of the positioning component 201, serving as the first anti-slip part 301, engages and fixes with the serrated structure on the lower side of the connecting component 101, serving as the second anti-slip part 302. This increases the stability of the connection between the connecting component 101 and the positioning component 201, preventing relative sliding between the connecting component 101 and the positioning component 201 during scaffolding use, and improving the safety and stability of the cantilevered scaffolding positioning connection device during use. During the installation of the scaffold body, the bottom of the scaffold upright is inserted into the mating pipe on the upper surface of the connector 101, which serves as the mating part 102, to fix the cantilever scaffold on the cantilever scaffold positioning connection device. During disassembly, after removing the scaffold body, the scaffold upright is first disconnected from the connector 102. Then, the locking bolts are loosened, allowing the positioning part 201 to rotate freely. The positioning part 201 is rotated from the first state to the second state, unlocking the connection between the positioning part 201 and the connector 101. This allows the cantilever scaffold positioning connection device to be completely removed from the I-beam. The device can then be reinstalled in other installation locations, enabling its detachable and reusable design.

[0059] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
