Technical Field
[0001] This utility model relates to the field of climbing scaffolding technology, specifically to a folding hanging frame structure for hanging netting on the top of a climbing scaffolding. Background Technology
[0002] Climbing scaffolding, also known as attached lifting scaffolding, is a new type of external scaffolding widely used in high-rise and super high-rise building construction due to its advantages such as low material consumption, low cost, high space utilization, convenient maintenance, and structural stability. Climbing scaffolding can be attached to the engineering structure and can ascend or descend layer by layer along with the structure using its own lifting equipment. During construction, for safety reasons, before lifting, all temporary support frames attached to the wall, movable parts of the steel chassis, diagonal braces, and horizontal safety nets must be checked to ensure they are completely detached from the wall. Lifting can only proceed after complete detachment.
[0003] During construction, to ensure worker safety, horizontal safety nets need to be installed in the gaps between the climbing scaffold and the structure. However, the top layer of the construction structure may not have readily available reliable netting points, often requiring the netting to be hung on the construction formwork. This not only reduces safety and increases operational difficulty, but also necessitates retracting the safety net before each lifting of the climbing scaffold, significantly increasing the complexity of formwork removal and scaffold lifting operations. This invention provides a foldable hanging frame structure for hanging netting on the top of a climbing scaffold to solve the above problems. Utility Model Content
[0004] This utility model provides a foldable hanging frame structure for hanging protective netting on the top of climbing scaffolding, which avoids the connection between the protective netting and the formwork, thereby improving safety and construction efficiency.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: A foldable hanging frame structure for hanging protective netting on the top of a climbing scaffold is provided. It includes a hanging beam, support rods, and mounting rods. The mounting rods are mounted on the top columns of the climbing scaffold, the hanging beams are mounted on the mounting rods, and the protective netting is hung on the hanging beams. The support rods are positioned between the hanging beams and the mounting rods. In use, the hanging beams, support rods, and mounting rods are interconnected to form a triangular structure. In storage, the support rods are folded within the hanging beams and mounting rods to form a strip-like structure. The hanging beam is provided with an adjustment groove, and the support rod is provided with an adjustment pin. The adjustment pin is located in the adjustment groove and is connected to the hanging beam.
[0006] Furthermore, the adjusting groove includes a strip groove and a toothed groove. Multiple toothed grooves are spaced apart and are all connected to the strip groove. In use, the adjusting pin is located in the toothed groove.
[0007] Furthermore, the adjusting pin includes a locking pin, a locking sleeve, and an anti-detachment pad. The locking pin is located at the outer end of the support rod, the locking sleeve and the anti-detachment pad are located at the outer end of the locking pin, and the anti-detachment pad is located between the locking sleeve and the hanging beam.
[0008] Furthermore, the anti-detachment pad is L-shaped and includes a gasket and an anti-detachment plate. The gasket is sleeved on the locking pin and located between the locking sleeve and the hanging beam. The anti-detachment plate is set perpendicular to the gasket and is located in the strip groove, contacting the bottom edge of the strip groove.
[0009] Furthermore, the inner end of the hanging beam is bolted to the top of the mounting rod, and the inner end of the support rod is bolted to the middle of the mounting rod.
[0010] Furthermore, the outer end of the hanging beam is provided with a connecting hole.
[0011] Preferably, the toothed groove is located above the strip groove.
[0012] Preferably, the hanging beam, support rod, and mounting rod are all angle steel.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.
[0018] like Figure 1 , 2 As shown in Figures 3 and 4, a foldable hanging frame structure for hanging netting on the top of a climbing scaffold is installed on the top of the climbing scaffold for hanging protective netting. It includes a hanging beam 1, a support rod 2, and an installation rod 3. The installation rod 3 is installed on the top column of the climbing scaffold, serving as a mounting base for the hanging beam 1 and the support rod 2. The hanging beam 1 is movably mounted on the installation rod 3 and can be adjusted in pitch around the connection point to accommodate gaps of different widths. The outer end of the hanging beam 1 contacts the template structure, and the protective netting is hung on the hanging beam 1 to protect the gap between the template structure and the climbing scaffold. The support rod 2 is positioned between the hanging beam 1 and the installation rod 3, serving to support the hanging beam 1. In the use state, the hanging beam 1, support rod 2, and installation rod 3 are interconnected to form a triangular structure. In the storage state, the support rod 2 is folded within the hanging beam 1 and installation rod 3 to form a strip structure, facilitating storage and saving space.
[0019] like Figure 1 , 2As shown in Figures 3, 4, and 5, the specific working principle of this utility model is as follows: The mounting rod 3 is fixed to the column at the top of the climbing frame by bolts. The inner end of the hanging beam 1 is movably connected to the top of the mounting rod 3 by bolts and can tilt around the bolts. The outer end of the hanging beam 1 contacts the template surface. The beam body of the hanging beam 1 seals the gap between the template and the climbing frame. After the edge of the protective net is attached to the outer end of the hanging beam 1, the gap can be protected to ensure safety. The bottom end of the support rod 2 is movably connected to the middle of the mounting rod 3 by bolts. The top end of the support rod 2 can be adjusted and set in the adjustment groove 11 in the middle of the hanging beam 1 by adjusting pin 21. The purpose of setting the support rod 2 is to support the hanging beam 1 and prevent the outer end of the hanging beam 1 from directly pressing against the template. When a heavy object falls, it will impact the template surface and damage the template structure. After setting the support rod 2, the impact is borne by the support rod 2 and transmitted to the mounting rod 3, which will not damage the template. Since the gap width between the climbing frame and the template is variable, the hanging beam 1, support rod 2 and installation rod 3 are designed to be adjustable to accommodate gaps of different widths, and can be folded into an approximate strip shape when folded, saving space when stored.
[0020] like Figure 9 As shown, the hanging beam 1 is provided with an adjustment groove 11, which is used to accommodate the connection and fixation of the adjustment pin 21 at the top of the support rod 2. The support rod 2 is provided with an adjustment pin 21, which is located in the adjustment groove 11 and connected to the hanging beam 1. When adapting to gaps of different widths, the pitch angle of the hanging beam 1 is adjusted first, which simultaneously changes the angle of the support rod 2. After adjustment, the adjustment pin 21 is locked to achieve a stable connection.
[0021] like Figure 9 As shown, the adjusting groove 11 further includes a strip groove and a toothed groove. Multiple toothed grooves are spaced apart and are all connected to the strip groove. The strip groove is used to adjust the position of the adjusting pin 21, and the toothed groove is used to adjust the stable support of the adjusting pin 21. In use, the adjusting pin 21 is located in the toothed groove and locked.
[0022] like Figure 6 , 7 As shown in Figure 8, the adjusting pin 21 further includes a pin 211, a locking sleeve 212, and an anti-detachment pad 213. The pin 211 is located at the outer end of the support rod 2, the locking sleeve 212 and the anti-detachment pad 213 are located at the outer end of the pin 211, and the anti-detachment pad 213 is located between the locking sleeve 212 and the hanging beam 1.
[0023] Due to significant vibrations during construction, the adjusting pin 21 often detaches from the toothed groove and shifts, causing the outer end of the hanging beam 1 to directly abut against the formwork surface, thus damaging the formwork surface, or getting stuck between the climbing frame and the formwork. This not only affects the movement of the climbing frame but also poses a safety hazard. Therefore, an anti-detachment pad 213 is installed in the adjusting pin 21 to prevent detachment. After installation, the upper part of the anti-detachment pad 213 is fixed to the pin 211, and the lower part abuts against the bottom edge of the strip groove. When vibration occurs, the pin 211 cannot detach from the toothed groove due to the supporting effect of the anti-detachment pad, thus preventing the adjusting pin 21 from detaching and shifting, effectively ensuring safety.
[0024] like Figure 7 , 8 As shown, the anti-detachment pad 213 is an integral L-shaped structure, including a pad and an anti-detachment plate. The pad is sleeved on the locking pin 211 and located between the locking sleeve 212 and the hanging beam 1. The anti-detachment plate is set perpendicular to the pad and forms an L-shaped structure with the pad. The anti-detachment plate is located in the strip groove and abuts against the bottom edge of the strip groove. When vibration occurs, since the anti-detachment pad 213 will not deform, it will support the locking pin 211 to be stably locked in the tooth groove.
[0025] In use, first align the top of the support rod 2 with the adjustment groove 11, then insert the locking pin 211 into the hole at the top of the support rod 2 and lock the locking pin 211 in the tooth groove. Then, put the anti-detachment pad 213 on the locking pin 211 and press the anti-detachment piece of the anti-detachment pad 213 against the bottom edge of the strip groove. Finally, install the locking sleeve 212 and lock it. When the angle of the hanging beam 1 needs to be adjusted, first loosen the locking sleeve 212, then pull the anti-detachment pad 213 outward to disengage it from the adjusting groove 11, or rotate the anti-detachment pad 213 to one side to release its support state. Then move the locking pin 211 from the tooth groove to the strip groove for position adjustment. Since the locking sleeve 212 has been loosened and the anti-detachment pad 213 has been manually deflected, when the locking pin 211 moves out of the tooth groove, it can automatically squeeze the anti-detachment pad 213 to continue to deflect it, without affecting the locking pin 211 from moving out of the tooth groove. After the locking pin 211 is adjusted into place and locked into the tooth groove, push the anti-detachment pad 213 inward to lock it into the strip groove or rotate it to put it in a support state. Finally, tighten the locking sleeve 212.
[0026] Furthermore, the inner end of the hanging beam 1 is bolted to the top of the mounting rod 3, and the inner end of the support rod 2 is bolted to the middle of the mounting rod 3. A gasket is provided between the support rod 2 and the mounting rod 3 so that the support rod 2 is parallel to the hanging beam 1.
[0027] Furthermore, the outer end of the hanging beam 1 is provided with a connecting hole for installing the pull rope for attaching the protective net.
[0028] Preferably, the toothed groove is located above the strip groove.
[0029] Preferably, the hanging beam 1, the support rod 2, and the mounting rod 3 are all angle steel.
[0030] Preferably, the locking pin 211 is a bolt, the locking sleeve 212 is a nut, and the anti-loosening pad 213 is made of bent steel sheet.
[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
