Description

Technical Field

[0001] This utility model relates to the field of building exterior wall construction technology, and in particular to a cantilevered scaffold. Background Technology

[0002] After the initial construction of the building's exterior walls is completed, subsequent installation and construction of components such as the protective layer, curtain wall frame, and glass are usually required to further improve the exterior structure and aesthetics. However, due to limitations in building height and construction sequence, in certain situations, it is necessary to erect cantilevered scaffolding at a certain half-height position of the building's exterior walls. This provides a construction platform for areas above half-height of the building's exterior walls, allowing construction workers to conveniently and safely carry out facade installation and repair work at higher levels.

[0003] For example, Chinese utility model patent CN221168629U discloses a cantilevered scaffolding connection structure, which uses steel wire ropes to hold a cantilever beam. One end of the cantilever beam is fixed to the main building structure, while the other end is suspended in the air, supporting the scaffolding and forming a stable working platform at half the height of the building's exterior wall. However, existing cantilevered scaffolding has low erection flexibility, is difficult to dismantle and adjust, and has low structural stability. Once the cantilevered scaffolding is connected to the exterior wall, its dismantling and adjustment require many steps and time, greatly slowing down construction efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing cantilever scaffolding, such as complicated installation and dismantling steps, weak structural stability, difficulty in adjustment, and impact on construction efficiency, and to provide a cantilever scaffolding.

[0005] In a first aspect, this utility model provides a cantilevered scaffolding, comprising several spaced-apart support systems, with a working platform at the top of each support system for erecting the scaffolding; the support system includes hanging beams, cantilever beams, and support rods; the hanging beams are detachably installed in the wall via embedded parts; the hanging beams include a first beam and a second beam arranged side-by-side, spaced apart; one end of the hanging beam is fixedly connected to one end of the cantilever beam, one end of the support rod is located within the gap between the first beam and the second beam and abuts against the wall, and the other end of the support rod is fixedly connected to the cantilever beam; the working platform is located at the top of the cantilever beam.

[0006] The cantilevered scaffolding provided by this utility model simplifies the installation and dismantling process because the hanging beams are detachably installed on the wall via embedded parts. Installation only requires fixing the hanging beams to the wall using the embedded parts, and dismantling only requires removing the embedded parts, reducing the complex steps and time required by traditional methods. The detachable installation method allows the scaffolding to be quickly adjusted or removed when needed, thereby improving construction efficiency.

[0007] The first and second beams are spaced apart, forming a gap between them. The end of the support rod that abuts against the wall can be inserted into the gap, and the angle between the support rod and the wall can be selected according to actual needs, improving the flexibility of this cantilevered scaffold. At the same time, the first and second beams can achieve a similar effect to clamping the support rod, preventing the support rod from swaying left and right, further enhancing the stability of the scaffold during high-altitude operations, and ensuring that it can withstand dynamic loads and wind effects during construction.

[0008] The spaced-out support system supports the top working platform, providing a stable working surface that allows workers to operate safely and reduces the occurrence of accidents.

[0009] The cantilevered scaffolding provided by this utility model overcomes the shortcomings of existing technologies, such as complex installation and dismantling steps, weak structural stability, and difficulty in adjustment. It has significant advantages in terms of ease of construction, structural stability, adjustment flexibility, and safety, greatly improving construction efficiency and user experience.

[0010] Preferably, the embedded component includes an embedded pipe, a screw rod, and a nut; the embedded pipe is located within the wall, and an enlarged portion is provided at one end of the embedded pipe within the wall; the screw rod is screwed to the embedded pipe, the hanging beam is sleeved on the screw rod, the nut is screwed to the screw rod, the side wall of the hanging beam abuts against the wall, and the nut abuts against the side wall of the hanging beam away from the wall.

[0011] This structural design, with the embedded pipe built into the wall and featuring an expansion section, creates a mechanical anchor point within the wall, effectively preventing the pipe from being pulled out under stress, thus providing higher stability and reliability. Because the embedded pipe is built into the wall, the hanging beam can be quickly installed and removed using only screws and nuts, greatly improving construction convenience. This embedded component design allows for multiple uses in a construction project, reducing construction materials and installation costs, resulting in high economic benefits.

[0012] Preferably, it further includes a first reinforcing beam, which is fixedly connected to the hanging beam. The first reinforcing beam is located below the support rod, and adjacent support systems are connected through the first reinforcing beam.

[0013] With this structural arrangement, the first reinforcing beam is fixedly connected to the hanging beam and located below the support rod, providing additional support and effectively preventing the support rod from slipping or failing. It forms a robust lateral support frame throughout the scaffolding system, improving bending and torsional resistance and making the cantilevered scaffolding more stable during high-altitude operations. Adjacent support systems, connected by the first reinforcing beam, form an even more stable overall structure. This connection method effectively distributes loads from all directions, reducing the stress on individual support systems and preventing localized deformation or instability.

[0014] Preferably, the system further includes a second reinforcing beam, which is fixedly connected to the hanging beam. The second reinforcing beam is located below the cantilever beam and abuts against the lower part of the cantilever beam. Adjacent support systems are connected through the second reinforcing beam.

[0015] This structural design, with the addition of a second reinforcing beam, provides extra support and reinforcement to the cantilever beam, improving its longitudinal load-bearing capacity and effectively reducing sagging or deformation caused by gravity and construction loads. This extends the service life of the scaffolding and makes the cantilever beam more stable and reliable under gravity and construction loads. The second reinforcing beam connects adjacent support systems, forming a more robust overall structure, further enhancing the overall rigidity of the cantilever scaffolding. It not only distributes loads from all directions but also prevents localized deformation, ensuring the stability of the entire scaffolding during high-altitude operations.

[0016] Preferably, it further includes a second reinforcing beam, which is fixedly connected to the hanging beam. The second reinforcing beam is located below the cantilever beam and abuts against the lower part of the cantilever beam. Adjacent support systems are connected through the second reinforcing beam. The first reinforcing beam and the second reinforcing beam are connected through a third reinforcing beam, and at least one third reinforcing beam is provided between two adjacent support systems.

[0017] This structural arrangement connects the first and second reinforcing beams via a third reinforcing beam, forming a multi-dimensional reinforcement network that increases the scaffold's resistance to lateral and torsional forces. This layout tightly links the various support systems, creating a complete frame structure that effectively improves the overall rigidity and stability of the scaffold.

[0018] Preferably, the third reinforcing beam intersects the hanging beam at an angle.

[0019] The third reinforcing beam connects the second and third reinforcing beams at an angle, acting as a diagonal brace in the overall structure and enhancing its shear and torsional resistance. This layout effectively resists structural torsional and shear deformation caused by wind, vibration, or external impacts during construction. Through the diagonal connection, this cantilevered scaffold forms a complex load-bearing structure, allowing forces to be more effectively distributed and transmitted through the diagonal beams, preventing excessive deformation of the structure due to forces acting in a single direction.

[0020] Preferably, the inclination directions of two adjacent third reinforcing beams are opposite.

[0021] This structural arrangement, with adjacent third reinforcing beams tilted in opposite directions, creates a symmetrical layout for the scaffolding. This symmetrical arrangement helps balance force and stress distribution, ensuring the stability of the entire scaffolding under multi-directional forces and preventing tilting or imbalance due to greater force on one side. The symmetrical oblique design provides a uniform force transmission path, resulting in better balance and stability of the structure under lateral and longitudinal forces.

[0022] Preferably, it also includes a fourth reinforcing beam, through which two adjacent cantilever beams are connected.

[0023] With this structural design, adjacent cantilever beams are connected by a fourth reinforcing beam, forming a complete lateral support structure. This connection method effectively improves the overall stability of the cantilever scaffolding, preventing individual cantilever beams from shifting or deforming under load. The cantilever beams can better support the upper working platform, making the entire structure more robust and reliable.

[0024] Preferably, at least one fourth reinforcing beam is provided between two adjacent cantilever beams, and the fourth reinforcing beam is oblique to the cantilever beam.

[0025] With this structural design, the fourth reinforcing beam forms an oblique support, which can effectively resist tilting and lateral displacement caused by external loads or wind, thereby improving the overall rigidity of the cantilevered scaffold.

[0026] Preferably, the inclination directions of two adjacent fourth reinforcing beams are opposite.

[0027] This structural arrangement, with adjacent fourth reinforcing beams tilted in opposite directions, creates a symmetrical layout for the scaffolding. This results in a more balanced stress distribution, distributing the load evenly across multiple components. This uniform stress distribution helps reduce the risk of any single component bearing excessive pressure, thereby improving the structure's durability.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] 1. The cantilevered scaffolding provided by this utility model simplifies the installation and dismantling process because the hanging beams are detachably installed on the wall via embedded parts. Installation only requires fixing the hanging beams to the wall using the embedded parts, and dismantling only requires removing the embedded parts, reducing the complex steps and time required in traditional methods. The detachable installation method allows the scaffolding to be quickly adjusted or removed when needed, thereby improving construction efficiency.

[0030] 2. The cantilevered scaffolding provided by this utility model features a first beam and a second beam spaced apart, forming a gap between them. The end of the support rod that abuts against the wall can be inserted into this gap. The angle between the support rod and the wall can be selected according to actual needs, improving the flexibility of the cantilevered scaffolding. Simultaneously, the first and second beams can achieve a similar effect to clamping the support rod, preventing it from swaying left and right, further enhancing the stability of the scaffolding during high-altitude operations and ensuring its ability to withstand dynamic loads and wind effects during construction. The spaced-apart support system supports the top working platform, providing a stable working surface, allowing construction workers to operate safely and reducing the occurrence of accidents.

[0045] Example 1

[0046] This embodiment provides a cantilevered scaffold that can be erected at half the height of the building's exterior wall without affecting the construction of the lower structure.

[0047] Specifically, such as Figures 1-5 As shown, the cantilevered scaffolding includes several spaced-apart support systems (e.g., Figure 1 (This shows a configuration of four support systems arranged from left to right). A work platform 5 is installed on top of the support system, which is used for erecting scaffolding. The support system includes a hanging beam 1, a cantilever beam 2, and a support rod 3.

[0048] Furthermore, such as Figure 1 As shown, a guardrail 300 can also be installed on the work platform 5. The guardrail 300 surrounds the work platform 5 and is used to prevent construction workers from accidentally falling from the work platform 5. Figure 1 As shown, the work platform 5 can be a crisscrossing fence-like structure. Figure 1 The structure of the scaffold is not shown, but it can be understood that the scaffold can be erected on the working platform 5.

[0049] The hanging beam 1 can be detachably installed on the wall 100 via the embedded part 4;

[0050] Specifically, such as Figure 2 , Figure 4As shown, the embedded part 4 includes an embedded pipe 41, a screw rod 42, and a nut 43. The embedded pipe 41 is embedded in the wall 100. One end of the embedded pipe 41 located in the wall 100 is provided with an enlarged part 411. The outer diameter of the enlarged part 411 is larger than the outer diameter of the embedded pipe 41, so that the embedded pipe 41 can be firmly embedded in the wall 100. The screw rod 42 is screwed to the embedded pipe 41. The hanging beam 1 has a through hole for the screw rod 42 to pass through. The hanging beam 1 is sleeved on the screw rod 42 through the through hole. After the screw rod 42 passes through the through hole, the nut 43 can be tightened. The nut 43 is screwed to the screw rod 42. The side wall of the hanging beam 1 abuts against the wall 100, and the nut 43 abuts against the side wall of the hanging beam 1 away from the wall 100.

[0051] With this structural design, the embedded pipe 41 is built into the wall 100 and has an expansion portion 411. This design creates a mechanical anchor point within the wall 100, effectively preventing the embedded pipe 41 from being pulled out of the wall 100 under stress, thus providing higher stability and reliability. Since the embedded pipe 41 is built into the wall 100, the hanging beam 1 can be quickly installed and removed using only screws 42 and nuts 43, greatly improving the convenience of construction. This embedded component 4 design allows for multiple uses in construction projects, reducing construction materials and installation costs, resulting in high economic benefits.

[0052] like Figure 1 , Figure 5 As shown, the hanging beam 1 includes a first beam 11 and a second beam 12 arranged side by side, for example, the first beam 11 and the second beam 12 are parallel to each other and are spaced apart; the hanging beam 1 is fixedly connected to one end of the cantilever beam 2, one end of the support rod 3 is located in the gap 200 between the first beam 11 and the second beam 12, the end of the support rod 3 located in the gap 200 abuts against the wall 100, and the other end of the support rod 3 is fixedly connected to the cantilever beam 2, so that the hanging beam 1, the cantilever beam 2, and the support rod 3 together form a stable right-angled triangle structure, and the working platform 5 is located on the top of the cantilever beam 2, and the specific working platform 5 can be welded to the cantilever beam 2.

[0053] The cantilevered scaffolding provided in this embodiment simplifies installation and dismantling because the hanging beam 1 is detachably installed on the wall 100 via embedded parts 4. During installation, only the hanging beam 1 needs to be fixed to the wall 100 via the embedded parts 4; during dismantling, only the embedded parts 4 need to be removed to quickly remove the hanging beam 1 from the wall 100. This embodiment only requires the installation of embedded parts at the contact point between the hanging beam 1 and the wall 100, eliminating the need for other structures connected to the wall 100, thus reducing the complex installation and dismantling steps and time required in traditional methods. The detachable installation method allows the scaffolding to be quickly adjusted or removed when needed, thereby improving construction efficiency.

[0054] The first beam 11 and the second beam 12 are spaced apart, forming a gap 200 between them. The end of the support rod 3 that abuts against the wall 100 can be inserted into the gap 200. The angle between the support rod 3 and the wall 100 can be selected according to actual needs, which improves the flexibility of the cantilevered scaffold. At the same time, the first beam 11 and the second beam 12 can achieve a similar effect to clamping the support rod 3, preventing the support rod 3 from swaying left and right, further enhancing the stability of the scaffold in high-altitude operations, and ensuring that it can withstand the dynamic loads and wind effects during construction.

[0055] The spaced-out support system supports the top working platform 5, providing a stable construction surface that allows construction workers to operate safely and reduces the occurrence of accidents.

[0056] The cantilevered scaffolding provided by this utility model overcomes the shortcomings of existing technologies, such as complex installation and dismantling steps, weak structural stability, and difficulty in adjustment. It has significant advantages in terms of ease of construction, structural stability, adjustment flexibility, and safety, greatly improving construction efficiency and user experience.

[0057] Example 2

[0058] like Figure 1 , Figure 2 , Figure 3 As shown, based on Embodiment 1, the cantilever scaffolding provided in this embodiment further includes a first reinforcing beam 61. The first reinforcing beam 61 is fixedly connected to the hanging beam 1 and is located below the support rod 3. Adjacent support systems are connected through the first reinforcing beam 61. With this structural arrangement, the first reinforcing beam 61, fixedly connected to the hanging beam 1 and located below the support rod 3, provides additional support, effectively preventing the support rod 3 from sliding or failing. The fixed connection between the first reinforcing beam 61 and the first beam body 11 and the second beam body 12 also strengthens the connection tightness between them. It forms a robust lateral support frame throughout the scaffolding system, improving bending and torsional resistance, making the cantilever scaffolding more stable during high-altitude operations. Adjacent support systems, connected through the first reinforcing beam 61, form a more stable overall structure. This connection method effectively distributes loads from all directions, reduces the stress on individual support systems, and prevents local deformation or instability.

[0059] Furthermore, the cantilever scaffolding provided in this embodiment also includes a second reinforcing beam 62, which is fixedly connected to the hanging beam 1. The second reinforcing beam 62 is located below the cantilever beam 2, and its top abuts against the bottom of the cantilever beam 2. Adjacent support systems are connected through the second reinforcing beam 62. With this structural arrangement, the addition of the second reinforcing beam 62 provides additional support and reinforcement to the cantilever beam 2. The fixed connection between the second reinforcing beam 62 and the first beam 11 and the second beam 12 also strengthens the connection between the first beam 11 and the second beam 12, improves the longitudinal bearing capacity, and effectively reduces the sagging or deformation of the cantilever beam 2 due to gravity and construction loads, thereby extending the service life of the scaffolding and making the cantilever beam 2 more stable and reliable when bearing gravity and construction loads. The second reinforcing beam 62 connects adjacent support systems to form a more robust overall structure, further improving the overall rigidity of the cantilever scaffolding. It can not only distribute loads from all directions, but also prevent local deformation, ensuring the stability of the entire scaffolding during high-altitude operations.

[0060] Example 3

[0061] Based on Embodiment 2, the cantilevered scaffolding provided in this embodiment further includes a third reinforcing beam 63 and a fourth reinforcing beam 64. Specifically, as shown... Figure 1 , Figure 3 As shown, the first reinforcing beam 61 and the second reinforcing beam 62 are connected by a third reinforcing beam 63, and at least one third reinforcing beam 63 is provided between two adjacent support systems. With this structural arrangement, the first reinforcing beam 61 and the second reinforcing beam 62 are connected by the third reinforcing beam 63, forming a multi-dimensional reinforcement network that increases the scaffold's resistance to lateral and torsional forces. This layout tightly connects the various support systems, making the entire scaffold form a complete frame structure, effectively improving its overall rigidity and stability.

[0062] Furthermore, the third reinforcing beam 63 is oblique to the hanging beam 1; the inclination directions of two adjacent third reinforcing beams 63 are opposite.

[0063] With this structural arrangement, the adjacent third reinforcing beams 63 have opposite inclination directions, creating a symmetrical arrangement of the scaffolding. For example... Figure 1From left to right, the first third reinforcing beam 63 extends in the upper left-lower right direction, the second third reinforcing beam 63 extends in the lower left-upper right direction, and the third third reinforcing beam 63 extends in the upper left-lower right direction. This arrangement allows the third reinforcing beams 63 to act as diagonal braces, enhancing their shear and torsional resistance. This layout effectively resists structural torsional and shear deformation caused by wind, vibration, or external impacts during construction; at the same time, this symmetrical arrangement helps to balance the force and stress distribution, ensuring that the entire scaffolding remains stable under multi-directional forces and does not tilt or become unbalanced due to greater force on one side.

[0064] Furthermore, adjacent cantilever beams 2 are connected by a fourth reinforcing beam 64. This structural arrangement connects adjacent cantilever beams 2 to form a complete lateral support structure. This connection method effectively improves the overall stability of the cantilever scaffold, preventing displacement or deformation of individual cantilever beams 2 under stress. The cantilever beams 2 can better support the upper working platform 5, making the entire structure more robust and reliable.

[0065] Furthermore, at least one fourth reinforcing beam 64 is provided between two adjacent cantilever beams 2. The fourth reinforcing beam 64 is oblique to the cantilever beam 2, and the inclination directions of two adjacent fourth reinforcing beams 64 are opposite.

[0066] With this structural arrangement, the fourth reinforcing beam 64 forms an oblique support, effectively resisting tilting and lateral displacement caused by external loads or wind, thus improving the overall rigidity of the cantilevered scaffold. The adjacent fourth reinforcing beams 64 have opposite tilting directions, creating a symmetrical arrangement of the scaffold structure. For example… Figure 3 From left to right, the first fourth reinforcing beam 64 extends in a lower left-upper right direction, the second fourth reinforcing beam 64 extends in a higher left-lower right direction, and the third fourth reinforcing beam 64 also extends in a lower left-upper right direction. This layout makes the stress distribution more balanced, distributing the load evenly across multiple components. This uniform stress distribution helps reduce the risk of any single component bearing excessive pressure, thereby improving the structure's durability.

[0067] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
