Description

Technical Field

[0001] This invention relates to the technical field of construction equipment, and specifically to an installation structure for an attached lifting scaffold. Background Technology

[0002] Attached lifting scaffolding is a widely used, liftable external protective equipment during the construction of the main structure and exterior wall decoration of high-rise buildings. Attached to the exterior wall of the building structure, it rises and falls layer by layer as construction progresses, providing a safe working platform and protective barrier for construction workers. Walkway panels, as a core component of attached lifting scaffolding, are laid on the horizontal trusses of each layer of the scaffolding. They are mainly used for supporting the movement of construction workers and for the temporary storage of construction tools and building materials. The connection structure between the walkway panels and the scaffolding directly determines the installation efficiency, safety, and ease of maintenance of the scaffolding.

[0003] Currently, in existing technologies, the walkway panels of attached lifting scaffolds are generally connected to the scaffold body using bolt fastening. During construction, workers first move each walkway panel to its corresponding installation position on the scaffold body and perform preliminary alignment. Then, using wrenches and other specialized tools, they sequentially pass multiple sets of bolts through the pre-drilled connection holes on the walkway panel and the scaffold body, and finally tighten the nuts one by one to complete the fixation.

[0004] Since dozens of walkway slabs are typically laid on each floor of the frame, and each walkway slab requires multiple sets of bolts, the entire installation process requires workers to repeatedly bend over, resulting in high labor intensity. Furthermore, the installation of a single walkway slab takes a long time, leading to low overall construction efficiency.

[0005] In summary, how to solve the problems of low disassembly and assembly efficiency and long overall construction cycle between existing scaffolding and walkway panels has become an urgent issue for those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides an installation structure for an attached lifting scaffold to solve the problems of low disassembly and assembly efficiency between the scaffold body and the walkway panels and long overall construction cycle.

[0007] To achieve the above objectives, the present invention provides the following technical solution: An installation structure for an attached lifting scaffold includes a frame, walkways, and a plug-in mechanism. The frame includes uprights and trusses, diagonal supports, and horizontal supports fixedly installed between two adjacent uprights. The bottom sides of the walkways abut against the trusses of the frame. The plug-in mechanism includes multiple limiting brackets, connecting brackets, and locking components. The trusses have multiple spaced mounting holes, and the walkways have corresponding mating holes. The limiting brackets slide through the mating holes and can be inserted into the mounting holes. The connecting brackets and the locking components are both located inside the frame. The limiting brackets include a first bracket and a second bracket. The connecting brackets are kinetically connected to the first bracket and the second bracket, respectively, such that when the first bracket is inserted into the mounting hole, it drives the second bracket out of the mounting hole, and when the second bracket is inserted into the mounting hole, it drives the first bracket out of the mounting hole. The locking components are used to lock the insertion state of the first bracket in the mounting hole.

[0008] According to one embodiment of the present invention, a first insert rod is fixedly disposed at the bottom of the first insert holder, a second insert rod is fixedly disposed at the bottom of the second insert holder, and a first push block and a second push block are fixedly disposed at the top of the connecting frame. The bottom of the first insert rod is opposite to the top of the first push block and can abut against it for transmission, and the bottom of the second insert rod is opposite to the top of the second push block and can abut against it for transmission. A first inclined surface is disposed at the bottom of the first insert rod, a second inclined surface is disposed at the bottom of the second insert rod, a third inclined surface is disposed at the top of the first push block that slides against the first inclined surface, and a fourth inclined surface is disposed at the top of the second push block that slides against the second inclined surface.

[0009] According to one embodiment of the present invention, the locking assembly includes a limiting frame, a limiting block, and a first spring. The limiting frame is fixedly disposed within the frame body, and the limiting block is slidably connected to the limiting frame along the radial direction of the mounting hole. A limiting slot is formed on the first insert. A guide groove is formed on the limiting frame, and a guide block is fixedly disposed on the limiting block and slidably connected to the guide groove. The first spring is disposed within the guide groove, with one end of the first spring abutting against the limiting frame and the other end of the first spring abutting against the limiting block.

[0010] According to one embodiment of the present invention, the locking assembly further includes an unlocking bracket and a second spring. The unlocking bracket is slidably connected to the frame body along the axial direction of the mounting hole. The top of the limiting block is provided with a fifth inclined surface, and the bottom of the unlocking bracket is provided with a sixth inclined surface that slidably abuts against the fifth inclined surface. A guide post is fixedly provided inside the frame body. The unlocking bracket has a guide hole that slidably engages with the guide post. The second spring is wound around the outside of the guide post. A support ring is provided at the end of the guide post away from the mounting hole. One end of the second spring abuts against the support ring, and the other end of the second spring abuts against the bottom of the unlocking bracket. The insertion mechanism further includes a third insert, which is slidably inserted into the mating hole and can be slidably inserted towards the mounting hole. The bottom of the third insert abuts against the top of the unlocking bracket for transmission.

[0011] According to one embodiment of the present invention, the insertion mechanism further includes a limiting sleeve and a protective cover. The limiting sleeve is fixedly disposed at the upper end of the mating hole. The side wall of the limiting bracket has an axially extending limiting groove. The inner side wall of the limiting sleeve is fixedly disposed with a limiting block that slides with the limiting groove. One end of the protective cover is fixedly connected to the top of the limiting bracket, and the other end of the protective cover is fixedly connected to the top surface of the walkway plate and covers the outside of the limiting sleeve. The protective cover has a retractable accordion-style structure.

[0012] The advantages of this invention compared to the prior art are: By pressing down the first insert bracket, it is inserted into the mounting hole of the scaffold body along the mating hole. The locking component restricts the axial sliding of the first insert bracket within the mounting hole, thus locking it in the inserted state and achieving a secure connection between the walkway panel and the scaffold body. The entire connection process relies on the insertion action of the limiting insert bracket and the locking action of the locking component to achieve fixation. There are no tightening steps requiring special tools, avoiding the high-intensity work of workers repeatedly bending over to tighten multiple sets of bolts one by one. This improves the efficiency of assembling and disassembling the walkway panels of the attached lifting scaffold and effectively shortens the overall construction cycle.

[0013] Through the reverse transmission cooperation of the first and second inserts and the connecting frame, during installation, simply press down on the first insert. As the first insert insert enters the mounting hole of the scaffold, the connecting frame automatically pulls the second insert out of the mounting hole, and the locking component automatically engages to lock the insertion state of the first insert, completing a secure connection between the walkway panel and the scaffold in one step. During disassembly, simply press down on the second insert. As the second insert insert enters the mounting hole of the scaffold, the connecting frame automatically pulls the first insert out of the mounting hole, detaching the walkway panel from the scaffold in one step. This single-step pressing operation significantly reduces the number of steps involved in assembly and disassembly, further improving the efficiency of assembling and disassembling walkways on attached lifting scaffolds. Furthermore, all assembly and disassembly actions are vertical downward pressing operations, and the top of the insert has a sufficiently large flat operating surface, allowing workers to not only press by hand but also directly step on the insert to complete the assembly and disassembly work without bending over or squatting, reducing physical strain.

[0014] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0024] like Figures 1 to 7 As shown, an installation structure for an attached lifting scaffold includes a frame 1, a walkway 2, and a plug-in mechanism 3. The frame 1 includes uprights, as well as a truss 13, a diagonal support 14, and a horizontal support 15 fixedly installed between two adjacent uprights.

[0025] The bottom sides of the walkway 2 abut against the truss 13 of the frame 1. The insertion mechanism 3 includes multiple limiting brackets 31, connecting brackets 32, and locking components 33. The truss 13 has multiple spaced mounting holes 11, and the walkway 2 has mating holes 21 that correspond to and communicate with the mounting holes 11. The limiting brackets 31 slide through the mating holes 21 and can be inserted into the mounting holes 11. The connecting brackets 32 and the locking components 33 are both located inside the frame 1. The limiting bracket 31 includes a first bracket 311 and a second bracket 312. The connecting bracket 32 ​​is convexly connected to the first bracket 311 and the second bracket 312 respectively, such that when the first bracket 311 is inserted into the mounting hole 11, it drives the second bracket 312 out of the mounting hole 11, and when the second bracket 312 is inserted into the mounting hole 11, it drives the first bracket 311 out of the mounting hole 11. The locking component 33 is used to lock the insertion state of the first bracket 311 in the mounting hole 11.

[0026] During installation, firstly, the walkway panel 2 is moved to the corresponding installation position on the frame 1. The walkway panel 2 is adjusted so that its bottom sides abut against the top of the frame 1, and the mating holes 21 on the walkway panel 2 are aligned with the mounting holes 11 on the top of the frame 1. Then, the first insert 311 is pressed down, sliding downwards along the mating holes 21 and inserting into the mounting holes 11 of the frame 1. During this process, the first insert 311, through its transmission connection with the connecting frame 32, drives the connecting frame 32 to slide inside the frame 1, thereby driving the second insert 312 to slide upwards along the mating holes 21, causing the second insert 312 to exit the mounting holes 11. Once the first insert 311 is fully inserted into the mounting holes 11, the locking component 33 located inside the frame 1 restricts the axial sliding of the first insert 311 along the mounting holes 11, locking the first insert 311 in the inserted state, thus achieving a secure connection between the walkway panel 2 and the frame 1.

[0027] During disassembly, firstly, release the locking constraint of the locking component 33 on the first insert 311. Then, press down on the second insert 312. The second insert 312 slides downward along the mating hole 21 and inserts into the mounting hole 11 of the frame 1. During this process, the second insert 312, through its transmission connection with the connecting frame 32, drives the connecting frame 32 to slide in the opposite direction inside the frame 1, thereby driving the first insert 311 to slide upward along the mating hole 21, so that the first insert 311 completely exits the mounting hole 11. At this point, the insertion connection between the walkway 2 and the frame 1 is released, and the walkway 2 can be directly removed from the frame 1, completing the disassembly operation.

[0028] By pressing down the first insert 311, the first insert 311 is inserted into the mounting hole 11 of the frame 1 along the mating hole 21. The locking component 33 restricts the axial sliding of the first insert 311 in the mounting hole 11, thereby locking the first insert 311 in the inserted state, thus achieving a firm connection between the walkway 2 and the frame 1. The entire connection process relies on the insertion action of the limiting insert 31 and the locking component 33 to achieve fixation. There are no tightening steps that require special tools, avoiding the high-intensity work of workers repeatedly bending over to tighten multiple sets of bolts one by one. This improves the assembly and disassembly efficiency of the attached lifting scaffold walkway 2 and effectively shortens the overall construction cycle.

[0029] Through the reverse transmission cooperation of the first insert 311, the second insert 312, and the connecting frame 32, during installation, only the first insert 311 needs to be pressed down. As the first insert 311 inserts into the mounting hole 11 of the frame 1, the second insert 312 automatically exits the mounting hole 11 via the connecting frame 32. The locking component 33 automatically engages to lock the insertion state of the first insert 311, thus completing a secure connection between the walkway 2 and the frame 1 in one step. During disassembly, only the second insert 312 needs to be pressed down. As the second insert 312 inserts into the mounting hole 11 of the frame 1, the first insert 311 automatically exits the mounting hole 11 via the connecting frame 32, thus terminating the connection between the walkway 2 and the frame 1 in one step. This single-step pressing operation significantly reduces the number of disassembly and assembly steps, further improving the efficiency of disassembly and assembly of the attached lifting scaffold walkway 2. Meanwhile, all disassembly and assembly operations are vertical downward pressing operations, and the top of the bracket is equipped with a flat operating area with sufficient area. Therefore, workers can not only press with their hands, but also directly step on the bracket to complete the disassembly and assembly operations without bending over or squatting, thus reducing physical strain.

[0030] According to one embodiment of the present invention, a first insert rod 314 is fixedly disposed at the bottom of the first insert bracket 311, a second insert rod 315 is fixedly disposed at the bottom of the second insert bracket 312, and a first push block 321 and a second push block 322 are fixedly disposed at the top of the connecting bracket 32. The bottom of the first insert rod 314 is opposite to the top of the first push block 321 and can abut against each other for transmission. The bottom of the second insert rod 315 is opposite to the top of the second push block 322 and can abut against each other for transmission. A first inclined surface 3141 is disposed at the bottom of the first insert rod 314, a second inclined surface 3151 is disposed at the bottom of the second insert rod 315, a third inclined surface 3211 is disposed at the top of the first push block 321 that slides against the first inclined surface 3141, and a fourth inclined surface 3221 is disposed at the top of the second push block 322 that slides against the second inclined surface 3151.

[0031] When the first insert 311 is pressed down, the first insert rod 314 moves downward synchronously with the first insert 311. The first inclined surface 3141 at the bottom of the first insert rod 314 slides and abuts against the third inclined surface 3211 at the top of the first push block 321, converting the vertical pressing force of the first insert 311 into the horizontal thrust of the connecting frame 32, driving the connecting frame 32 to slide horizontally. When the connecting frame 32 slides, it drives the second push block 322 to move synchronously. The fourth inclined surface 3221 at the top of the second push block 322 slides and abuts against the second inclined surface 3151 at the bottom of the second insert rod 315, converting the horizontal thrust of the connecting frame 32 into the vertical lifting force of the second insert 312, driving the second insert 312 to slide upward along the mating hole 21 and exit the mounting hole 11. When the second insert 312 is pressed down, the second insert rod 315 moves down synchronously with the second insert 312. The second inclined surface 3151 and the fourth inclined surface 3221 cooperate to drive the connecting frame 32 to slide horizontally in the opposite direction. Then, the first insert 311 is driven to slide upward and exit the mounting hole 11 through the cooperation of the first push block 321 and the first insert rod 314.

[0032] According to one embodiment of the present invention, the locking assembly 33 includes a limiting frame 331, a limiting block 332, and a first spring 333. The limiting frame 331 is fixedly disposed within the frame 1. The limiting block 332 is slidably connected to the limiting frame 331 along the radial direction of the mounting hole 11. A limiting slot 3111 is provided on the first insert 311. A guide groove 3311 is provided on the limiting frame 331. A guide block 3321 that is slidably connected to the guide groove 3311 is fixedly disposed on the limiting block 332. The first spring 333 is disposed within the guide groove 3311. One end of the first spring 333 abuts against the limiting frame 331, and the other end of the first spring 333 abuts against the limiting block 332.

[0033] When the first insert 311 is inserted downward into the mounting hole 11, the bottom sidewall of the first insert 311 abuts against the fifth inclined surface 3322 of the end of the limiting block 332, pushing the limiting block 332 to slide away from the mounting hole 11 along the guide groove 3311, while compressing the first spring 333 to store elastic potential energy. When the first insert 311 is fully inserted into the mounting hole 11 to a preset depth, the limiting groove 3111 on the sidewall of the first insert 311 aligns with the end of the limiting block 332, the first spring 333 releases its elastic potential energy, pushing the limiting block 332 to slide along the guide groove 3311 towards the mounting hole 11, so that the end of the limiting block 332 is engaged in the limiting groove 3111, thereby restricting the axial sliding of the first insert 311 and achieving automatic locking.

[0034] According to one embodiment of the present invention, the locking assembly 33 further includes an unlocking bracket 334 and a second spring 335. The unlocking bracket 334 is slidably connected to the frame body 1 along the axial direction of the mounting hole 11. The top of the limiting block 332 is provided with a fifth inclined surface 3322, and the bottom of the unlocking bracket 334 is provided with a sixth inclined surface 3341 that slidably abuts against the fifth inclined surface 3322. A guide post 12 is fixedly provided inside the frame body 1. The unlocking bracket 334 is provided with a guide hole 3342 that slidably engages with the guide post 12. The second spring 335 is wound around the outside of the guide post 12. A support ring 121 is provided at the end of the guide post 12 away from the mounting hole 11. One end of the second spring 335 abuts against the support ring 121, and the other end of the second spring 335 abuts against the bottom of the unlocking bracket 334. The insertion mechanism 3 further includes a third insert 313, which is slidably inserted into the mating hole 21 and can be slidably inserted into the mounting hole 11. The bottom of the third insert 313 abuts against the top of the unlocking bracket 334 for transmission.

[0035] When it is necessary to disassemble the walkway panel 2, press down on the third insert 313. The third insert 313 pushes the unlocking bracket 334 to slide downward along the guide post 12, while compressing the second spring 335 to store elastic potential energy. During the downward sliding process of the unlocking bracket 334, the sixth inclined surface 3341 at its bottom slides and abuts against the fifth inclined surface 3322 at the top of the limiting block 332, converting the vertical pressing force of the unlocking bracket 334 into the radial thrust of the limiting block 332. This pushes the limiting block 332 to overcome the elastic force of the first spring 333 and slide along the guide groove 3311 away from the mounting hole 11, so that the end of the limiting block 332 completely exits the limiting groove 3111 on the side wall of the first insert 311, automatically releasing the axial locking constraint on the first insert 311. At this time, continue to press down on the second insert 312, and the first insert 311 will slide upward and exit the mounting hole 11 through the reverse transmission of the connecting bracket 32, completing the disassembly of the walkway panel 2. After the third insert 313 is released, the second spring 335 releases its elastic potential energy, pushing the unlocking bracket 334 to slide upward along the guide post 12 to reset.

[0036] According to one embodiment of the present invention, the insertion mechanism 3 further includes a limiting sleeve 34 and a protective cover 35. The limiting sleeve 34 is fixedly disposed at the upper end port of the mating hole 21. The side wall of the limiting bracket 31 is provided with an axially extending limiting groove 316. The inner side wall of the limiting sleeve 34 is fixedly disposed with a limiting block 341 that slides with the limiting groove 316. One end of the protective cover 35 is fixedly connected to the top of the limiting bracket 31, and the other end of the protective cover 35 is fixedly connected to the top surface of the walkway plate 2 and covers the outside of the limiting sleeve 34. The protective cover 35 is a retractable accordion-style structure.

[0037] When the limiting bracket 31 slides up and down within the mating hole 21, the limiting block 341 on the inner side of the limiting sleeve 34 slides synchronously along the limiting groove 316 on the side wall of the limiting bracket 31, limiting the maximum sliding stroke of the limiting bracket 31 and preventing the limiting bracket 31 from falling out of the mating hole 21. The accordion-style protective cover 35 extends and retracts synchronously with the up and down sliding of the limiting bracket 31, always completely covering the outside of the limiting sleeve 34, blocking external contaminants such as dust, mortar, and rainwater from entering the mating hole 21 and the interior of the frame 1, protecting the internal transmission structure and locking assembly 33.

[0038] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios: First, move the walkway plate 2 to the corresponding installation position on the truss 13 of the frame 1, and adjust it so that its bottom sides are fully in contact with the top surface of the truss 13. At the same time, align and connect the mating holes 21 on the walkway plate 2 with the mounting holes 11 on the truss 13. Then, press down on the first insert 311. The first insert 311 slides down along the mating hole 21 and inserts into the mounting hole 11. The first inclined surface 3141 of the first insert rod 314 at its bottom slides and abuts against the third inclined surface 3211 of the first push block 321 on the connecting frame 32, converting the vertical pressing force into the horizontal thrust of the connecting frame 32, driving the connecting frame 32 to slide horizontally. The connecting frame 32 simultaneously drives the second push block 322 to move. Through the cooperation of the fourth inclined surface 3221 and the second inclined surface 3151 of the second insert rod 315, the horizontal thrust is converted into the vertical lifting force of the second insert 312, causing the second insert 312 to automatically exit the mounting hole 11.

[0039] When the first insert 311 is fully inserted to the preset depth, the limiting slot 3111 on the side wall of the first insert 311 aligns with the end of the limiting block 332. The first spring 333 releases its elastic potential energy to push the limiting block 332 into the limiting slot 3111, automatically locking the axial position of the first insert 311 and completing the firm connection between the walkway 2 and the frame 1.

[0040] During disassembly, first press down on the third insert 313. The third insert 313 pushes the unlocking bracket 334 to slide down along the guide post 12 and compress the second spring 335. The sixth inclined surface 3341 at the bottom of the unlocking bracket 334 slides and abuts against the fifth inclined surface 3322 at the top of the limiting block 332, converting the vertical pressing force into a radial thrust, pushing the limiting block 332 to overcome the elastic force of the first spring 333 and exit the limiting slot 3111, automatically releasing the locking constraint on the first insert 311.

[0041] Then, the second insert 312 is pressed down, and it slides down along the mating hole 21 into the mounting hole 11. The second insert 312 is driven to slide horizontally in the opposite direction by the inclined surface of the second insert rod 315 and the second push block 322. Then, the first insert 311 is driven to completely exit the mounting hole 11 by the cooperation of the first push block 321 and the first insert rod 314. At this time, the plug-in connection between the walkway 2 and the frame 1 is completely released, and the walkway 2 can be directly removed from the top surface of the truss 13. Finally, after the third insert 313 is released, the second spring 335 releases its elastic potential energy to push the unlocking bracket 334 to slide upward along the guide post 12 to reset. The limit block 332 returns to the initial locked position synchronously under the action of the first spring 333.

[0042] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
