Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and in particular to an installation base for cantilevered scaffolding. Background Technology

[0002] In the construction of high-rise and super high-rise buildings, cantilevered scaffolding is widely used as a key temporary support structure. Its core components include cantilevered steel beams perpendicular to the building and scaffolding systems mounted on these beams. Traditional installation methods require on-site welding at the top of the cantilevered steel beams to fix the positioning reinforcing bars, after which the scaffolding uprights are inserted into the positioning bars for positioning. However, this process faces multiple challenges in practical application: welding operations at height require construction workers to carry welding equipment, significantly increasing the difficulty and safety risks of the work; simultaneously, welding and subsequent cutting processes cause irreversible thermal damage and structural weakening to the cantilevered steel beams, making them unusable and significantly increasing construction costs and wasting resources. Summary of the Invention

[0003] The main objective of this invention is to provide an installation base for cantilever scaffolding, which aims to improve installation safety and facilitate reuse.

[0004] To achieve the above objectives, the mounting base for the cantilever scaffolding proposed in this invention includes: Pre-embedded reinforcing bars, wherein the pre-embedded reinforcing bars are embedded to the horizontal plane of the building, and partially exposed above the horizontal plane of the building; A cantilevered steel beam, which is connected to the pre-embedded steel bars, and the cantilevered steel beam extends out of the building facade; Two mounting bases are provided, which are detachably mounted on the portion of the cantilevered steel beam extending out of the building facade. The two mounting bases are spaced apart, and each mounting base has a positioning column at its top. The scaffolding column is inserted into the positioning column.

[0005] In one embodiment, the cantilever beam is an I-beam, and the mounting base includes: A sliding block is provided with a sliding groove, which is slidably disposed on the upper half of the I-beam. The bottom of the sliding block is provided with multiple lead screws, which extend downward. A locking block is located below the I-beam. The locking block has multiple through holes through which the lead screw passes. A nut is installed on the lead screw and is located below the locking block to hold the locking block against the bottom of the I-beam, thereby fixing the mounting base.

[0006] In one embodiment, a washer is provided between the nut and the locking block.

[0007] In one embodiment, the groove is a T-shaped groove, and the upper half of the I-beam passes through the T-shaped groove.

[0008] In one embodiment, the top of the positioning post is provided with a foolproof structure.

[0009] In one embodiment, the mounting base of the cantilever scaffold further includes a support structure, the support structure including a support diagonal rod located below the I-beam, one end of the support diagonal rod being fixed to the building facade, and the other end being connected to the end of the I-beam.

[0010] In one embodiment, the support structure further includes two support columns, which are spaced apart at the top of the support rod, and the top ends of the two support columns respectively abut against the bottom surfaces of the two locking blocks.

[0011] In one embodiment, the top surface of the supporting diagonal rod has two planes at both ends, and the two supporting columns are installed on the two planes.

[0012] In one embodiment, the bottom surface of the locking block is provided with a positioning groove, and the top of the support column is inserted into the positioning groove. The positioning groove is provided to limit the horizontal direction of the mounting base.

The support structure is then installed, and the alignment of the two support columns with the bottom positioning groove of the locking block is observed. If the sliding column fails to extend and insert into the positioning groove, the position of the mounting seat is adjusted until the sliding column extends and inserts into the positioning groove, to ensure the consistency of the mounting seat position among the mounting bases of multiple cantilever scaffolds.

[0014] This application provides an installation base for cantilever scaffolding. Through the design of a detachable installation base, traditional welding operations are avoided, thereby improving installation safety and efficiency. It has the advantages of being safe, reliable, and easy to reuse. Attached Figure Description

[0022] When installing the scaffolding uprights, the existing cantilever scaffolding requires welding positioning steel bars to the top of the cantilever steel beams, which presents problems such as high difficulty and high risk of high-altitude welding operations; at the same time, welding and cutting operations will damage the cantilever steel beams, which is not conducive to their reuse.

[0023] In response, this application proposes a mounting base 1000 for cantilever scaffolding; please refer to [link / reference]. Figures 1 to 4 The mounting base 1000 of the cantilever scaffold includes: a pre-embedded steel bar 1, which is pre-embedded to the building horizontal plane 42 and partially exposed above the building horizontal plane 42; a cantilever steel beam, which is connected to the pre-embedded steel bar 1 and partially extends out of the building facade; and two mounting seats 3, which are detachably mounted on the portion of the cantilever steel beam extending out of the building facade, with the two mounting seats 3 spaced apart, and a positioning column 31 provided on the top of the mounting seat 3, into which the scaffolding column is inserted.

[0024] For ease of understanding, the following explains some key terms in this embodiment: The 1000 mounting base for cantilever scaffolding is designed to provide a stable mounting foundation for cantilever scaffolding during the construction of high-rise or super high-rise buildings. This base, connected to the main building structure, transfers the load of the scaffolding to the building structure.

[0025] The embedded steel bar 1 refers to a steel reinforcement component that is pre-embedded inside the building's horizontal plane 42 during the construction of the main building structure, with some ends protruding from the building's horizontal plane 42. This embedded steel bar 1 serves as a connector to reliably connect the cantilevered steel beam to the main building structure.

[0026] A cantilevered steel beam is a steel beam component that is connected to the main structure of the building at one end and cantilevered out of the building facade at the other end. This cantilevered steel beam serves as the main load-bearing component, supporting the load of the mounting base 3 and the scaffolding.

[0027] Mounting bracket 3 is designed to be detachably mounted on the cantilevered portion of the cantilevered steel beam. Mounting bracket 3 serves as a connector for the scaffolding uprights, providing positioning and support for the uprights.

[0028] Positioning post 31 is located on top of mounting base 3. Positioning post 31 is used to guide and secure the bottom of the scaffolding uprights, ensuring accurate installation of the scaffolding uprights.

[0029] The scaffolding uprights are the main vertical support components in the cantilevered scaffolding structure. The bottom of the scaffolding uprights is inserted into the positioning columns 31 to form the vertical support system of the scaffolding.

[0030] One end of the cantilevered steel beam is connected to the aforementioned pre-embedded reinforcing bar 1. The connection can be made using bolts, pins, or welding to ensure stability. The other part of the cantilevered steel beam is designed to extend beyond the building facade, forming a cantilever structure to support the scaffolding. For example, the cantilevered steel beam can be made of rectangular steel pipes, H-beams, or channel steel.

[0031] Two mounting bases 3 are detachably installed on the portion of the cantilevered steel beam extending beyond the building facade. This detachable installation allows the mounting bases 3 to be adjusted, removed, or replaced as needed, thereby improving the system's flexibility and reusability. The two mounting bases 3 are spaced apart along the length of the cantilevered steel beam to provide stable support points. For example, the mounting bases 3 can be fixed to the cantilevered steel beam by means of clamps, bolts, or pins.

[0032] Each mounting base 3 is topped with a positioning post 31. This positioning post 31 is designed to guide and secure the bottom of the scaffolding upright. The scaffolding upright is inserted into the positioning post 31, enabling quick and accurate installation of the scaffolding upright and preventing horizontal displacement. For example, the positioning post 31 can be a simple cylindrical steel pipe with an inner diameter matching the outer diameter of the scaffolding upright.

[0033] The cantilever scaffolding installation base in this embodiment, through the connection method of pre-embedded steel bars 1 to the cantilever steel beam, and the design of detachable mounting base 3 and positioning column 31, effectively avoids the dangers and construction difficulties of traditional high-altitude welding and cutting operations. This solution protects the integrity of the cantilever steel beam, extends its service life, and improves the reusability of components, thereby reducing material costs.

[0034] Please see Figures 1 to 3This application further proposes that, in the mounting base 1000 of the cantilever scaffold, the cantilever steel beam is an I-beam 2, and the mounting base 3 includes a sliding block 32, the sliding block 32 is provided with a sliding groove, the sliding groove is slidably disposed on the upper half of the I-beam 2, the bottom of the sliding block 32 is provided with a plurality of lead screws 34, the lead screws 34 are provided downward; a locking block 33 is located below the I-beam 2, the locking block 33 is provided with a plurality of through holes, the lead screws 34 pass through the through holes, and a nut 35 is installed on the lead screw 34, the nut 35 is located below the locking block 33, so as to hold the locking block 33 against the bottom of the I-beam 2, so as to complete the fixing of the mounting base 3.

[0035] The mounting base 3 further includes a sliding block 32. The sliding block 32 is a key component in the mounting base 3 for position adjustment, and it is typically made of high-strength metal to ensure structural integrity under scaffold loads. The structural design of the sliding block 32 allows it to fit tightly with the upper part of the I-beam 2, thereby allowing the mounting base 3 to move along the length of the I-beam 2 while ensuring stability.

[0036] The sliding block 32 is provided with a groove, which is slidably disposed on the upper half of the I-beam 2. The groove can be a recess inside the sliding block 32 or a clamping structure on the outside of the sliding block 32, and its shape and size match the upper flange or upper profile of the I-beam 2. Through the sliding engagement of the groove with the upper half of the I-beam 2, the mounting base 3 can be precisely adjusted in lateral position on the I-beam 2 to adapt to the spacing requirements of different scaffolding columns or the specific layout of the construction site.

[0037] The above technical solution specifically defines the cantilevered steel beam as an I-beam 2, and uses a clamping structure composed of a sliding block 32, a locking block 33, a screw rod 34, and a nut 35 to fix the mounting base 3, effectively solving the problems of unstable fixing and inconvenient adjustment of the mounting base 3 on the cantilevered steel beam. This solution allows the mounting base 3 to be precisely slidably adjusted along the length of the I-beam 2 to adapt to different scaffolding spacing requirements. Simultaneously, the tightening action of the screw rod 34 and the nut 35 securely clamps the sliding block 32 and the locking block 33 to the upper and lower sides of the I-beam 2, forming a stable and reliable connection and ensuring the stability of the scaffolding column installation. Furthermore, this structural design facilitates the rapid installation, disassembly, and position adjustment of the mounting base 3, improving construction efficiency and flexibility.

[0038] This application further proposes that a gasket be provided between the nut 35 and the locking block 33.

[0039] Please see Figure 4 This application further proposes that the aforementioned groove is a T-shaped groove 321, and the upper half of the aforementioned I-beam 2 passes through the aforementioned T-shaped groove 321.

[0040] Specifically, the T-slot 321 is a slot with a specific cross-sectional shape, characterized by a narrower upper section and a wider lower section, forming an overall "T" shape. This structural design aims to provide excellent mechanical interlocking capability, effectively limiting the relative movement of the connected parts in the vertical direction and enhancing their resistance to torsion and lateral displacement. The T-slot 321 can be manufactured through various processes such as milling, casting, or extrusion molding. Its dimensional accuracy and surface finish are crucial for ensuring smooth sliding and a stable connection.

[0041] Meanwhile, the upper half of the aforementioned I-beam 2 passes through the aforementioned T-slot 321, which describes the specific fit between the T-slot 321 and the I-beam 2. The upper half of the I-beam 2, typically referring to its upper flange and part of its web, is designed to be precisely inserted into and slide within the T-slot 321. In this configuration, the large lower space of the T-slot 321 can cover the bottom of the upper flange of the I-beam 2, forming a robust locking structure, thereby effectively preventing the sliding block 32 from lifting off or detaching from the I-beam 2. At the same time, the narrow opening of the T-slot 321 guides and limits the web of the I-beam 2, ensuring that the sliding block 32 slides smoothly along a predetermined path on the I-beam 2 and resists lateral displacement. This insertion method greatly improves the overall rigidity and stability of the connection between the sliding block 32 and the I-beam 2. The interlocking fit between the T-slot 321 and the I-beam 2 forms a more robust mechanical connection, significantly enhancing the resistance to vertical pull-out and lateral displacement between the mounting base 3 and the cantilevered steel beam. This not only ensures the positional stability of the mounting base 3 under the load of the scaffolding column, reducing the risk of loosening due to vibration or impact, but also provides a more solid and reliable foundation for subsequent tightening of the locking block 33 using the screw 34 and nut 35, thereby improving the overall structural safety and operational reliability of the cantilevered scaffolding mounting base.

[0042] Please see Figure 2 This application further proposes that the top of the positioning post 31 is provided with a foolproof structure. The foolproof structure is a guide slope.

[0043] Please see Figures 1 to 3 This application further proposes an installation base 1000 for cantilever scaffolding, which also includes a support structure 4. The support structure 4 includes a support diagonal rod 41, which is located below the I-beam 2. One end of the support diagonal rod 41 is fixed to the exterior facade of the building, and the other end is connected to the end of the I-beam 2.

[0044] Specifically, the support structure 4 is designed to provide additional mechanical support for the mounting base 1000 of the cantilever scaffolding, enhancing its overall rigidity and load-bearing capacity. This structure is typically made of high-strength steel and is designed to effectively transfer and distribute loads. The support diagonal brace 41 is a core component of the support structure 4, its main function being to form a stable triangular support system. Located below the I-beam 2, this diagonal brace, through its inclined arrangement, converts part of the vertical load acting on the I-beam 2 into axial force and transfers it to the building facade. The connection between the support diagonal brace 41 and the building facade can employ various reliable fixing methods, such as using expansion bolts. This fixing method requires ensuring that the strength and rigidity of the connection point are sufficient to withstand and transfer the axial force from the support diagonal brace 41, thereby effectively distributing the cantilever load to the main building structure. The connection between the support diagonal brace 41 and the end of the I-beam 2 is typically achieved through welded connecting plates, bolted connecting plates, or pin connections. For example, a connecting lug can be welded below the end of the I-beam 2, and the other end of the supporting diagonal rod 41 is bolted to the lug. This connection method is designed to ensure that the supporting diagonal rod 41 can effectively provide upward support to the cantilever end of the I-beam 2.

[0045] By introducing the support structure 4, particularly the support diagonal brace 41, the mounting base of this application significantly improves the overall stability and load-bearing capacity of the cantilever scaffold. The support diagonal brace 41 is located below the I-beam 2, with one end firmly fixed to the building facade and the other end connected to the end of the I-beam 2, thus forming a stable triangular support system. This support method effectively converts part of the vertical load borne by the cantilever steel beam into axial force and transfers it to the main building structure, avoiding potential safety risks caused by excessive deformation. This not only enhances the structural rigidity of the scaffold mounting base, enabling it to withstand greater working loads and external environmental influences, but also improves the safety and reliability of the entire cantilever scaffold system, ensuring the stability and safety of the construction process.

[0046] Please see Figure 2 and Figure 3 This application further proposes that the supporting structure 4 also includes two supporting columns 43. The supporting columns 43 are components used to provide vertical support. Their main function is to directly abut against the bottom surface of the supporting locking block 33, transferring the load borne by the locking block 33 downwards, thereby enhancing the supporting strength and stability of the locking block 33 and preventing displacement or deformation due to stress. The supporting columns 43 can be made of solid or hollow steel pipes, structural steel, or other materials. Their cross-sectional shape can be circular, square, or other suitable geometric shapes for stress distribution. Their height and strength need to be designed according to the expected load and structural requirements.

[0047] The two support columns 43 are spaced apart at the top of the support diagonal rod 41. This means that the support diagonal rod 41, as the main load-bearing component, further transfers the load transmitted by the support columns 43 downwards to the building facade. The spaced arrangement of the support columns 43 ensures uniform support for the locking block 33 and matches the size and position of the locking block 33. The support columns 43 can be fixed to the top of the support diagonal rod 41 by welding, bolting, or other mechanical connections. The determination of the spacing distance should take into account the size of the locking block 33, the stress distribution, and the arrangement of the scaffolding columns.

[0048] The tops of the two support columns 43 respectively abut against the bottom surfaces of the two locking blocks 33. This is the core function of this technical solution: by having the tops of the support columns 43 directly contact and support the bottom surfaces of the locking blocks 33, a direct force transmission path is formed. The vertical load of the scaffolding column is transmitted through the positioning column 31, mounting base 3, and locking block 33, ultimately to the support column 43, and then from the support column 43 to the support diagonal brace 41 and the building facade. This abutment method can be direct contact, or a buffer pad or connecting plate can be set between the two to optimize the force distribution.

[0049] Through the above technical solution, two support columns 43 are set at the top of the support diagonal rod 41, and their top ends directly abut against the bottom surface of the support locking block 33. The vertical load transmitted by the scaffold column can be directly and effectively transmitted to the support column 43 and the support diagonal rod 41 through the mounting seat 3 and the locking block 33, and then transmitted to the building facade by the support diagonal rod 41.

[0050] Please see Figure 2 This application further proposes that the top surfaces of the support diagonal rod 41 are two planes 42, and the two support columns 43 are installed on the two planes 42. This design provides a solid, flat and precise installation foundation for the support columns 43, improves the connection stability between the support columns 43 and the support diagonal rod 41, and ensures that the support columns 43 can accurately transmit force to the locking block 33, thereby enhancing the structural rigidity and load-bearing capacity of the entire cantilever scaffolding installation base.

[0051] Please see Figure 4 This application further proposes that the bottom surface of the locking block 33 is provided with a positioning groove 331, and the top of the support column 43 is inserted into the positioning groove 331. The positioning groove 331 is provided to limit the horizontal direction of the mounting base 3.

[0052] Specifically, the positioning groove 331 is a recessed structure on the bottom surface of the locking block 33. This positioning groove 331 can be designed in various geometric shapes, such as rectangular, circular, or V-shaped, to match the top shape of the support column 43. Its dimensions and depth are precisely designed to provide a tight and stable accommodating space for the top of the support column 43. By setting the positioning groove 331, the bottom of the locking block 33 is no longer a simple flat surface 42, but has the ability to precisely align and interlock with the support structure 4. Simultaneously, the top of the support column 43 is designed as a protruding structure that can mate with the positioning groove 331 on the bottom surface of the locking block 33. During installation, by precisely adjusting the position of the mounting base 3, the top of the support column 43 can be accurately aligned and inserted into the positioning groove 331. This plug-in mating method creates a mechanical interlocking relationship between the support column 43 and the locking block 33, rather than a simple contact support. The core function of the plug-in mating between the positioning groove 331 and the top of the support column 43 is to precisely limit the horizontal movement of the mounting base 3. Once the top of the support column 43 is inserted into the positioning groove 331, the inner wall of the positioning groove 331 will form a tight contact with the outer wall of the support column 43, thereby effectively preventing any undesirable movement of the mounting base 3 in the horizontal directions such as front-back, left-right, etc. This limiting effect ensures that the mounting base 3 maintains its preset horizontal position throughout its service life, thus providing a stable installation foundation for the scaffolding column.

[0053] Through the above technical solution, a positioning groove 331 is set on the bottom surface of the locking block 33, and the top of the support column 43 is inserted into the positioning groove 331, achieving precise horizontal positioning of the mounting base 3. This mechanically interlocked structure effectively solves the problem of horizontal displacement that may occur when relying solely on vertical support. Specifically, when the top of the support column 43 is inserted into the positioning groove 331, the wall of the positioning groove 331 forms a tight fit with the support column 43, which can effectively resist loads from the horizontal direction and prevent the mounting base 3 from sliding or shifting under the influence of wind, construction vibration, etc. This not only enhances the horizontal stability of the mounting base 3 and ensures the verticality of the scaffolding columns and the precise alignment of the overall structure, but also significantly improves the overall safety and reliability of the cantilevered scaffolding.

[0054] Please see Figure 4This application further proposes an improved support column 43 structure, which includes a column body 431, a sliding groove 4311, a sliding column 432, and a spring 433. The column body 431 has a sliding groove 4311 at its top, and the top surface of the column body 431 abuts against the bottom surface of the locking block 33. The sliding column 432 is slidably disposed within the sliding groove 4311, with the portion of the sliding column 432 protruding from the column body 431 inserted into the positioning groove 331. The spring 433 is disposed between the bottom of the sliding column 432 and the bottom surface of the sliding groove 4311. During installation, the I-beam 2 is first installed onto the pre-embedded reinforcing bar 1, then the two mounting seats 3 are installed to their preset positions on the I-beam 2, followed by the installation of the support structure 4. During this process, it is necessary to simultaneously observe the alignment of the two support columns 43 with the positioning groove 331 at the bottom of the locking block 33. If the sliding column 432 fails to extend and insert into the positioning slot 331, the position of the mounting base 3 needs to be adjusted until the sliding column 432 extends and inserts into the positioning slot 331, thereby ensuring the consistency of the position of the mounting base 3 among multiple cantilever scaffold mounting bases 1000.

[0055] Specifically, the column body 431 of the support column 43 is a key load-bearing component of the entire support structure 4. Its top is designed with a sliding groove 4311 to accommodate and guide the movement of the sliding column 432. The top surface of the column body 431 directly abuts against the bottom surface of the locking block 33, responsible for transferring the load from the cantilever steel beam to the support structure 4 through the locking block 33, and ultimately distributing it to the building facade. The column body 431 is typically made of high-strength steel to ensure its structural integrity and stability under heavy loads. The sliding groove 4311 is a precision-machined area located at the top of the column body 431. Its internal space matches the external dimensions of the sliding column 432, designed to provide a smooth and restricted sliding path for the sliding column 432. The depth and width of the sliding groove 4311 are precisely designed to ensure that the sliding column 432 can freely extend and retract under the action of the spring 433, while preventing unnecessary swaying or deviation in the lateral direction, thereby ensuring that the sliding column 432 can be accurately aligned and inserted into the positioning groove 331. The sliding post 432 is the core component of the support post 43 that enables self-adaptive alignment. It is cleverly positioned within the sliding groove 4311 inside the post body 431, allowing it to slide up and down within it. The portion of the sliding post 432 protruding from the post body 431 is designed to precisely insert into the positioning groove 331 on the bottom surface of the locking block 33. When the mounting base 3 is aligned with the support post 43, the telescopic characteristics of the sliding post 432 allow it to accommodate slight installation deviations and automatically insert into the positioning groove 331 when aligned accurately, thus achieving precise horizontal positioning. The sliding post 432 is typically made of wear-resistant, high-strength metal to ensure its long-term reliability. The spring 433 is cleverly placed between the bottom of the sliding post 432 and the bottom surface of the sliding groove 4311. Its main function is to provide a continuous upward thrust, ensuring that the sliding post 432 remains extended without external pressure. When the mounting base 3 and the support column 43 are not aligned, the bottom surface of the locking block 33 will press the sliding column 432, causing it to retract into the column body 431. Once aligned, the spring force of the spring 433 will immediately push the sliding column 432 out and insert it into the positioning groove 331. The selection of the spring 433 should take into account its stiffness and fatigue life to ensure that it can maintain stable performance during repeated installation and disassembly.

[0056] The entire installation process demonstrates the advantages of this improved structure. First, the I-beam 2 is securely installed onto the pre-embedded reinforcing steel 1, providing foundation support for the entire cantilever scaffolding system. Next, the two mounting seats 3 are initially installed into their preset positions on the I-beam 2, although some alignment deviation may exist at this stage. Subsequently, the support structure 4 is installed, bringing the support column 43 close to the bottom of the locking block 33. In this crucial step, the installers need to observe the alignment of the sliding column 432 on the two support columns 43 with the positioning groove 331 at the bottom of the locking block 33. If the sliding column 432 is pressed into the column body 431 by the locking block 33 due to misalignment and fails to extend and insert into the positioning groove 331, the installers can fine-tune the position of the mounting seat 3 based on the feedback from the sliding column 432. This adjustment continues until the sliding column 432 extends smoothly and accurately inserts into the positioning groove 331 under the action of the spring 433. This process not only simplifies the alignment operation, but more importantly, it ensures that each mounting base 3 in the multiple mounting bases 1000 of the cantilever scaffolding can be accurately positioned in the preset position by providing clear physical feedback, thereby ensuring the high consistency of the overall installation position.

[0057] Through the above technical solution, this application provides a support column 43 structure with adaptive alignment function. The spring 433 enables the sliding column 432 to automatically extend during installation and quickly and accurately insert itself into the positioning groove 331 at the bottom of the locking block 33 when aligned. This design greatly simplifies the alignment operation of the mounting base 3, transforming the complex process that originally required precise manual measurement into an intuitive "insertion into position" feedback mechanism. When the sliding column 432 fails to insert into the positioning groove 331, the installer can clearly perceive the alignment deviation and make targeted adjustments until the sliding column 432 is successfully inserted. This not only significantly improves installation efficiency and reduces installation time, but more importantly, it ensures a high degree of consistency and accuracy in the horizontal position of the mounting base 3 among multiple cantilever scaffold mounting bases 1000. This precise and consistent positioning is crucial for ensuring the overall structural stability, load-bearing capacity, and construction safety of the cantilever scaffold, effectively avoiding potential risks caused by installation deviations and improving the reliability and standardization level of the entire scaffolding system.
