Description

Technical Field

[0001] This utility model relates to the field of building construction scaffolding technology, and in particular to an attached cantilevered operating platform for scaffolding. Background Technology

[0002] In the construction industry, scaffolding is widely used in various projects due to its advantages such as stable structure, convenient erection, and strong load-bearing capacity. Cantilevered working platforms, as important auxiliary construction facilities attached to scaffolding, are mainly used to provide working space for construction workers and temporary material storage; their performance directly affects the safety and efficiency of construction.

[0003] However, existing attached cantilevered working platforms for scaffolding present several pressing problems in practical use. Firstly, traditional cantilevered working platforms have relatively fixed structures, making installation and dismantling cumbersome and time-consuming, hindering their ability to adapt to frequent changes in construction site conditions. Secondly, their stability and safety rely on complex support structures, which are prone to deformation and loosening under prolonged use or heavy loads, posing safety hazards. Furthermore, the cantilever components of most existing platforms cannot be flexibly retracted or extended, occupying significant space when not in use, impacting site layout and increasing transportation and storage costs. Therefore, there is an urgent need to design a more structurally sound, easy-to-operate, stable, and flexibly adjustable attached cantilevered working platform for scaffolding to meet the practical needs of modern construction. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by providing an attached cantilevered operating platform for scaffolding.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model provides an attached cantilevered operating platform for scaffolding, wherein the scaffolding includes horizontal scaffolding bars and vertical scaffolding bars;

[0007] The operating platform includes:

[0008] The cantilevered vertical poles are rotatably mounted on the scaffold horizontal poles via fasteners. At least two cantilevered vertical poles are provided, and steel mesh support poles are welded between the cantilevered vertical poles.

[0009] The end crossbars are welded at both ends to the ends of the cantilevered vertical members that extend outside the scaffold;

[0010] The first support rod has one end rotatably connected to the end of the cantilevered vertical rod, and the other end rotatably connected to the scaffold horizontal rod through the fastener, and the first support rod is slidably connected to the fastener;

[0011] A locking ring, the middle part of which is rotatably mounted on the first support rod by a threaded engagement, is located above the fastener. The locking ring can be rotated along the axial direction of the first support rod by the threaded engagement and abut against the fastener to limit the sliding stroke of the first support rod.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following:

[0013] The cantilevered vertical poles are rotatably mounted on the scaffold horizontal poles via fasteners, allowing for flexible switching between the retracted and extended states. This enables the operating platform to be conveniently deployed or retracted for storage according to construction needs, greatly improving operational flexibility while saving space resources on the construction site.

[0014] The steel mesh support rods welded between the cantilevered vertical poles provide stable support for the steel mesh, forming a safe and reliable platform for personnel to step on, ensuring the safety of construction workers when working on the platform.

[0015] The first support rod is rotatably connected to the end of the cantilevered vertical rod via a pivot, and is slidably and securely connected to the scaffold crossbar via a fastener. It can adaptively extend or retract according to changes in the distance between the end of the cantilevered vertical rod and the scaffold crossbar when the rod is retracted or extended, ensuring effective support for the cantilevered vertical rod in all states. Simultaneously, a locking ring is threaded onto the first support rod, which, when the cantilevered vertical rod is extended, engages with the fastener, limiting the sliding stroke of the first support rod, effectively tightening the end of the cantilevered vertical rod, preventing sagging, and further enhancing the structural stability of the operating platform.

[0016] The second support rod is fixed at one end to the support crossbar and connected at the other end to the scaffold vertical bar, forming a triangular structure with an acute angle with the cantilever vertical bar. Utilizing the stability principle of a triangle, it provides strong support to the end of the cantilever vertical bar from the bottom, greatly enhancing the stability of the entire operating platform and enabling it to withstand greater loads.

[0017] The handrails are detachably mounted on the end crossbars, providing safety protection when using the operating platform. They can be removed for transportation or storage, reducing space occupation and facilitating transport and storage.

[0018] The end crossbars and cantilevered vertical bars are welded together by a pivot, making the rotation between the components more flexible and smooth. At the same time, the components of the entire operating platform are connected by fasteners and other means, making the installation and disassembly process simple and quick, improving construction efficiency and reducing labor costs.

[0032] An attached cantilevered operating platform for scaffolding, the scaffolding including scaffolding horizontal bars 11 and scaffolding vertical bars 12;

[0033] The operating platform 20 includes:

[0034] The cantilevered vertical member 21, the middle section of which is rotatably mounted on the scaffold horizontal member 11 via a fastener, and at least two cantilevered vertical members 21 are arranged side by side. The cantilevered vertical member 21 has a retracted state and an extended state, such as... Figure 1 As shown, the cantilevered vertical rod 21 is in the extended state at this time, and the operating platform 20 is also extended, as shown. Figure 5 As shown, the cantilevered vertical pole 21 is in the retracted state. At this time, the operating platform 20 is retracted. In addition, steel mesh support poles 211 are welded between the cantilevered vertical poles 21. The steel mesh is placed on the steel mesh support poles 211 for personnel to step on.

[0035] An end crossbar 22, with both ends welded to the ends of the cantilevered vertical bar 21 extending outside the scaffold, and a handrail 221 detachably mounted on the end crossbar 22; furthermore, a pivot is fixedly mounted at both ends of the end crossbar 22; the pivot is welded to the ends of the cantilevered vertical bar 21 extending outside the scaffold; a first support rod 23 is rotatably mounted on the pivot, such as... Figure 6 As shown;

[0036] The first support rod 23 has one end rotatably connected to the end of the cantilevered vertical rod 21, and the other end rotatably connected to the scaffold horizontal rod 11 via a fastener. The first support rod 23 is slidably connected to the fastener. Since the distance between the end of the cantilevered vertical rod 21 and the first support rod 23 is different in the retracted and extended states, the first support rod 23 needs to be extended or retracted adaptively. Of course, after extension or retraction, the first support rod 23 needs to be fixed by the fastener to prevent the first support rod 23 from falling off.

[0037] The operating platform 20 further includes a locking ring 231, the middle of which is rotatably mounted on the first support rod 23 via a threaded engagement. Specifically, the first support rod 23 has a threaded section 232, and the threaded section 232 has an external thread (e.g., Figure 4 As shown in the figure (the external thread is not shown), the inner ring of the locking ring 231 has an internal thread that matches the external thread. The locking ring 231 is located above the fastener. The locking ring 231 can rotate along the axial direction of the first support rod 23 through the threaded engagement and abut against the fastener to limit the sliding stroke of the first support rod 23. Figure 1 As shown, after the cantilevered vertical rod 21 is in the unfolded state, the locking ring 231 moves axially along the first support rod 23 through a threaded engagement and abuts against the fastener to prevent the first support rod 23 from continuing to slide downward, thereby tightening the end of the cantilevered vertical rod 21 and preventing it from sagging.

[0038] In addition, the operating platform 20 further includes: a support crossbar 212, which is horizontally installed below the cantilevered vertical bar 21 via fasteners; a second support bar 24, one end of which is fixed to the support crossbar 212 via fasteners, and the other end of which is installed on the scaffolding vertical bar 12 via fasteners; the second support bar 24 and the cantilevered vertical bar 21 have an acute angle, and the second support bar 24 supports the end of the cantilevered vertical bar 21 from the bottom, forming a triangular structure, which enhances the structural stability. Figure 3 As shown.

[0039] It should be noted that when the operating platform 20 is in the retracted state, the handrail 221, the second support rod 24 and the support crossbar 212 need to be removed before it can be changed from the retracted state to the extended state.

[0040] In the retracted state, the cantilevered vertical member 21 hangs naturally, its axis aligned with that of the scaffold vertical member 12, as... Figure 5As shown, the first support rod 23 hangs down naturally, aligned with the outer facade of the scaffold. When switching to the extended state, first loosen the fastener's tightening force on the first support rod 23, allowing the first support rod 23 to extend and retract. Then rotate the cantilevered vertical rod 21 so that it forms a 90° angle with the scaffold vertical rod 12. Next, tighten the fastener's tightening force on the first support rod 23 so that the first support rod 23 cannot slide forward. Then, move the locking ring 231 along the axial direction of the first support rod 23 through a threaded engagement and press it against the fastener, further preventing the first support rod 23 from sliding forward. At this point, the cantilevered vertical rod 21 is initially stabilized. Then, install the support horizontal rod 212 below the cantilevered vertical rod 21. Finally, use the fastener to install one end of the second support rod 24 onto the support horizontal rod 212 and the other end onto the adjacent scaffold vertical rod 12, thus completing the state switch.
