Description

Technical Field

[0001] This utility model relates to the field of scaffolding, and in particular to a scaffolding for construction projects. Background Technology

[0002] Scaffolding provides a continuous passageway and working surface around the building, enabling workers of different trades to work in layers and at multiple points simultaneously, greatly reducing waiting and vertical transportation time, thereby shortening the overall construction period. The complex shape of modern buildings requires construction auxiliary facilities to have extremely high adaptability, so that they can build a support system that fits the structure and complete the tasks of the entire life cycle, such as main construction, exterior wall decoration, and equipment installation.

[0003] A search revealed that Chinese Patent Publication No. CN222362732U discloses a scaffolding for construction projects. The scaffolding is assembled by having both ends of a connecting rod inserted into a wedge-shaped connecting frame and by striking the connecting rod to make it fully inserted into the wedge-shaped connecting frame. This eliminates the need to assemble the scaffolding by tightening bolts, thus facilitating assembly.

[0004] In the above technical solution, the scaffolding is assembled by inserting connecting rods into wedge-type connecting frames. However, the scaffolding lacks protective functions and cannot quickly cover the working surface during sudden rainfall, increasing the risk of slipping and material scrapping. At the same time, in the absence of light or at night, there is a lack of convenient means to set up lighting, which can easily lead to misoperation and falls from heights, reducing construction safety and efficiency. Therefore, a new type of scaffolding for construction projects is proposed to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3This utility model provides an embodiment of a construction scaffold, comprising a scaffold 1 composed of multiple sets of uprights, horizontal bars, and diagonal braces. A load-bearing plate 2 is fixedly connected to the outer wall of the scaffold 1, capable of supporting construction workers standing and working, and accommodating the stacking of construction materials, thus improving operational convenience. A climbing ladder 3 is fixedly connected to the outer wall of the scaffold 1, facilitating safe movement of construction workers up and down between different heights of the scaffold 1 and reducing climbing risks. A protective structure 4 is provided on the outer wall of the scaffold 1, including an arc-shaped retaining ring 401. The inner surface of the arc-shaped retaining ring 401 is adapted to fit the outer wall of the scaffold 1, allowing for a tight fit and ensuring connection stability. The inner wall of the arc-shaped retaining ring 401 has an installation cavity 402, providing installation space for the magnetic strip 403 and preventing its exposure and damage. The magnetic strip 403 is fixedly connected to the inner wall of the installation cavity 402. The outer wall of the scaffold 1 is magnetically connected to the arc-shaped retaining ring 401 via the magnetic strip 403, eliminating the need for additional bolts and enabling quick installation and removal of the arc-shaped retaining ring 401. The magnetic strip 403 is made of high-magnetic neodymium iron boron permanent magnet material. The magnetic strips 403 are long and strip-shaped, and are continuously or evenly distributed along the circumferential direction of the inner wall of the mounting cavity 402 of the arc-shaped retaining ring 401. The uprights and horizontal bars of the scaffold 1 are made of carbon steel, which provides a good magnetic adsorption base for the magnetic strips 403. The tight adsorption of the magnetic strips 403 to the surface of the steel pipes of the scaffold 1 can generate sufficient magnetic attraction, thereby ensuring that the arc-shaped retaining ring 401 and the entire protective structure 4 remain stable under construction vibration and light wind conditions. The wrap angle of the arc-shaped retaining ring 401 is designed to be greater than 180 degrees, which further enhances the mechanical stability of the connection. A support block 404 is fixedly connected to the outer wall of the ring 401. An installation cylinder 405 is fixedly connected to the outer wall of the support block 404. An opening 406 is provided at the bottom of the installation cylinder 405. A rotating shaft 407 is rotatably connected to the inner wall of the installation cylinder 405, which can drive the rain curtain 409 to rotate synchronously, so as to realize the unfolding and retraction of the rain curtain 409. A coil spring 408 is fixedly connected to the outer wall of the rotating shaft 407. The fixed end of the coil spring 408 is fixedly connected to the inner wall of the installation cylinder 405 to ensure that the coil spring 408 can be stably stressed when the rotating shaft 407 rotates, and to prevent the coil spring 408 from falling off.

[0020] Reference Figures 1-3A rain curtain 409 is fixedly connected to the outer wall of the pivot 407 to shield against rain, strong sunlight, dust, and other debris, protecting the construction environment of the bearing plate 2 area. The rain curtain 409 is wrapped around the outer wall of the pivot 407, and the opening 406 is fitted onto the outer wall of the rain curtain 409 to limit its movement and prevent it from shifting. A fixing strip 410 is fixedly connected to the bottom of the rain curtain 409 to increase its weight and prevent it from being blown away by the wind. It also facilitates the installation of the hook 411. The bottom of the fixing strip 410 is fixedly connected to the hook 411, which can be hooked onto the outer wall of the scaffold 1 to lock the rain curtain 409 in its unfolded state. The outer wall of the hook 411 is adapted to the outer wall of the scaffold 1. A flexible light strip 412 is fixedly connected to the outer wall, which can provide illumination in low-light environments and improve the working visibility in the area of ​​the support plate 2. The flexible light strip 412 is fixedly connected to the outer wall of the rain curtain 409 near the support plate 2, which can accurately illuminate the core construction area. The power supply line of the flexible light strip 412 is not shown in the figure. It is led out from near the connection point with the rain curtain 409 and is designed with redundant length. The power supply line can be temporarily routed along the frame of the scaffold 1 and temporarily fixed with cable ties. Finally, it is connected to a portable mobile power supply or a low-voltage safety power interface at the construction site located at the bottom of the scaffold 1 or the working platform. This is a conventional power supply technology in the construction engineering field. When the rain curtain 409 is rolled up, the power supply line can be rolled up synchronously with it or stored separately after the cable ties are untied.

[0021] Reference Figures 4-5The outer wall of the mounting cylinder 405 is provided with a protective auxiliary component 5, which includes a mounting frame 501. The mounting frame 501 is fixedly connected to the outer wall of the mounting cylinder 405, specifically to the side of the outer wall of the mounting cylinder 405 closest to the flexible light strip 412. A rotating rod 502 is rotatably connected to the inner wall of the mounting frame 501, which can drive the fixed sleeve 503 and the moving rod 504 to adjust their angles to adapt to the hanging point requirements of different working scenarios. The outer wall of the rotating rod 502 is fixedly connected to the fixed sleeve 503, providing a sliding channel for the moving rod 504 and enabling the extension and retraction function of the moving rod 504. The inner wall of the fixed sleeve 503 is slidably connected to the moving rod 504, and a hanging groove 5 is provided at the top of the moving rod 504. 05. The movable rod 504 can slide inside the fixed sleeve 503 to achieve telescopic displacement. A spring pin 506 is fixedly connected to the top of the movable rod 504. A positioning hole 507 is opened on the top of the fixed sleeve 503. The outer wall of the movable end of the spring pin 506 is adapted to the inner wall of the positioning hole 507. The spring pin 506 is a standard commercial ball plunger. In its natural state, the spring inside pushes out the steel ball part to form a raised positioning part. When it is necessary to adjust the extension length of the movable rod 504, the user needs to apply a certain pulling force to overcome the preload of the spring inside the spring pin 506, so that the steel ball retracts, and the movable rod 504 can slide smoothly inside the fixed sleeve 503. When the hanging groove 5 on the top of the movable rod 504... When the spring pin 506 is moved to a suitable height and the steel ball is aligned with one of the positioning holes 507 on the fixed sleeve 503, the steel ball quickly springs into the positioning hole 507 under the action of the spring. This mechanical interlocking method ensures reliable positioning of the moving rod 504, preventing accidental retraction. A rectangular groove 508 is provided at the end of the rotating rod 502. A folding plate 509 is hinged to the outer wall of the mounting bracket 501. A rectangular block 510 is fixedly connected to the outer wall of the folding plate 509, magnetically connecting to the rectangular groove 508 to enhance the stability of the angle locking of the rotating rod 502. The inner wall of the rectangular groove 508 is magnetically connected to the outer wall of the rectangular block 510, eliminating the need for additional fasteners and enabling quick locking and unlocking of the rotating rod 502. The rectangular groove 508 at both ends is embedded with a first magnet. The rectangular block 510 on the folding plate 509 is made of magnetic metal material such as low carbon steel, or has a second magnet with the opposite polarity to the first magnet embedded inside. When the folding plate 509 is closed, the rectangular block 510 is inserted into the rectangular groove 508 and is fixedly positioned by magnetic attraction. This magnetic connection is mainly used to overcome the weight of the rotating rod 502 and minor daily contact, keeping it at the angle preset by the user. The main load is still borne by the rotating connection shaft between the mounting frame 501 and the rotating rod 502. Through the limiting of the rectangular block 510 and the rectangular groove 508, the moving rod 504 forms a foldable safety belt attachment point, solving the problem of insufficient temporary attachment points during high-altitude operations.

[0022] Working principle: Scaffold 1 is first constructed by connecting multiple sets of uprights, horizontal bars, and diagonal braces to form the core support frame, providing a stable foundation for the overall structure. The load-bearing plate 2 supports construction personnel and materials, meeting the load-bearing requirements during operation. The climbing ladder 3 provides a passage for construction personnel to move between different heights on scaffold 1, ensuring safe passage. Based on protection requirements, the arc-shaped retaining ring 401 is fitted onto the outer wall of the corresponding upright or horizontal bar of scaffold 1. Through the magnetic attraction of the magnetic strip 403 to the outer wall of scaffold 1, the arc-shaped retaining ring 401 is quickly connected to scaffold 1, and the mounting cylinder 405 is then stably fixed to scaffold 1. On the outside, when encountering rainy weather or needing to shield against external debris, workers pull the fixing strip 410 at the bottom of the rain curtain 409. Under this force, the rain curtain 409 rotates the rotating shaft 407. During rotation, the rotating shaft 407 stretches the coil spring 408 fixed to its outer wall, causing the spring 408 to twist and store elastic potential energy. The rain curtain 409 gradually unfolds downwards along the opening 406 at the bottom of the mounting cylinder 405 until it completely covers the area of ​​the bearing plate 2. Then, the hook 411 at the bottom of the fixing strip 410 is attached to any horizontal or vertical bar on the outer wall of the scaffold 1, thus securing the rain curtain 409 in its unfolded state and providing rain protection. In low-light construction environments, the flexible light strip 412 fixed to the outer wall of the rain curtain 409 near the support plate 2 can be opened to provide lighting for the work area of ​​the support plate 2 and improve the clarity of the work field. When construction workers need to use temporary safety belt attachment points, they first flip the folding plate 509 hinged to the mounting frame 501, so that the rectangular block 510 on the outer wall of the folding plate 509 disengages from the rectangular groove 508 at the end of the rotating rod 502, releasing the restriction on the rotating rod 502. Then, the rotating rod 502 is rotated to a suitable angle, and then, according to the actual work requirements, the moving rod 504 is pulled to slide and extend within the inner wall of the fixed sleeve 503 to adjust the extension length of the moving rod 504. Once the movable rod 504 is adjusted to the target length, the movable end of the spring pin 506 fixed at its top pops out under its own elasticity and snaps into the corresponding positioning hole 507 at the top of the fixed sleeve 503, thus achieving relative fixation between the movable rod 504 and the fixed sleeve 503. Finally, the folding plate 509 is reset, allowing the rectangular block 510 to re-embed into the rectangular groove 508 at the end of the rotating rod 502, and further reinforced by magnetic connection. At this time, the hanging groove 505 at the top of the movable rod 504 can be used as a foldable safety belt hanging point for construction workers to hang safety belts to ensure the safety of high-altitude operations. When the hanging point is no longer needed, the movable rod 504 can be stored and reset by reversing the steps.
