Description

Technical Field

[0001] This utility model relates to the field of climbing scaffolding technology, specifically a novel support-free device for climbing scaffolding. Background Technology

[0002] In building construction, attached lifting scaffolding is a new type of scaffolding system that has been widely used in recent years. It is mainly used in high-rise shear wall buildings. During on-site construction, a leveling frame needs to be erected to support the climbing scaffolding in the early stage. At least three wall supports must be installed before the bottom leveling frame can be dismantled. Commonly, the leveling frame is a frame device for leveling the bottom of the climbing scaffolding by erecting disc-lock or steel pipe coupler scaffolding. This frame device is not suitable for buildings with high first floors, and it has high requirements for the quality of the frame erection. In addition, it occupies some frame materials and generates certain rental costs. Furthermore, when the foundation construction of the construction hoist is carried out later, the leveling frame must be dismantled before the foundation concrete construction can be carried out, which delays the time of the main building's secondary structure and affects the construction progress.

[0003] In the prior art, a novel support-free device for climbing scaffolds can be adapted for construction on each floor of the first floor by installing pre-embedded bolts inside the wall. It eliminates the need for scaffolding materials for support, reducing material usage and saving costs. It also allows the foundation of the construction hoist to be completed in advance, thereby enabling secondary structure construction to proceed earlier and accelerating the project construction progress.

[0004] Because the internal protective devices of the above-mentioned devices are prone to damage after prolonged use, and the protective devices are fixed to the new supportless device of the climbing scaffold and are difficult to disassemble, which may affect the safety of the operators, this utility model proposes a new supportless device for climbing scaffold to solve the above problems.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1 to 4 This utility model provides a technical solution: a novel supportless device for climbing scaffolds, the novel supportless device for climbing scaffolds includes: a support frame 1, pre-embedded bolts 2 installed on the side wall of the support frame 1, the pre-embedded bolts 2 being located inside the wall, a through groove 3 opened on the side wall of the support frame 1, a long plate 4 installed on the top of the support frame 1, a limiting block 5 installed on the bottom of the long plate 4, a take-up groove 6 opened on the side wall of the limiting block 5, a fastening component 7 installed through the inside of the take-up groove 6, the fastening component 7 passing through the side wall of the through groove 3, the fastening component 7 including a threaded rod 8, the threaded rod 8 passing through the side wall of the limiting block 5, a fixing sleeve 9 installed on the outer end of the threaded rod 8, a handle 10 installed on the inner end of the threaded rod 8, and a nut 11 installed on the outer surface of the threaded rod 8;

[0022] In use, the pre-embedded bolts 2 are located inside the wall, and the support frame 1 is easily fixed to the side wall of the wall by the pre-embedded bolts 2. The connecting device on the outside is installed on the support frame 1 by the connecting plate and bolts, and the attached lifting scaffold is connected by bolts. The protective uprights, horizontal bars and protective plates of the protective device are installed on the long plate 4 by bolts. The limiting block 5 is located inside the support frame 1. By moving the handle 10 in the fastening assembly 7, the fixing sleeve 9 is moved out of the inside of the receiving groove 6 and the through groove 3 from the side wall of the support frame 1, and the fixing sleeve 9 is rotated from the horizontal direction to the vertical direction. Pull the handle 10 so that the inner side wall of the fixing sleeve 9 is attached to the outer side wall of the support frame 1. Tighten the nut 11 to restrict the movement of the threaded rod 8 and fix the long plate 4 and the protective device.

[0023] Example 2: Based on Example 1, a structure is provided to prevent the threaded rod 8 from rotating and to tightly fix the long plate 4 and the support frame 1 to prevent the long plate 4 from sliding. A rotating rod 12 is installed through the center of the fixed sleeve 9. A rotating plate 13 is installed at the outer end of the rotating rod 12. The rotating plate 13 is fixed to the side wall of the fixed sleeve 9. A drive gear 14 is installed on the outer surface of the rotating rod 12. A toothed plate 15 is installed in mesh with the teeth of the drive gear 14. The toothed plate 15 is placed symmetrically along the center of the drive gear 14 and is located inside the fixed sleeve 9. A clamping plate 16 is installed at the outer end of the toothed plate 15.

[0024] In use, rotating the rotating plate 13 drives the rotating rod 12 to rotate, which in turn drives the driving gear 14 to rotate. The teeth of the driving gear 14 mesh with the teeth of the toothed plate 15, thereby driving the clamping plates 16 on both sides to move synchronously in opposite directions. This makes it easy to move the clamping plates 16 to be close to the upper surface of the long plate 4 and the lower surface of the support frame 1, thus clamping the support frame 1 and the long plate 4 together.

[0025] Example 3: Based on Example 2, a structure for limiting and fixing the rotating plate 13 is provided. A limiting plate 17 is installed on the side wall of the fixing sleeve 9. A movable locking block 18 is installed through the center of the limiting plate 17. Several baffles 19 are evenly distributed in a ring array on the side wall of the rotating plate 13. The movable locking block 18 moves between two adjacent baffles 19.

[0026] In use, the movable block 18 moves upward to facilitate the rotation of the drive gear 14 driven by the rotating plate 13, thereby adjusting the position of the clamping plate 16. After the position is adjusted, the movable block 18 is moved downward so that the bottom end of the movable block 18 moves between the two adjacent baffles 19, which can restrict the rotation of the rotating plate 13.

[0027] In actual use, the pre-embedded bolts 2 are located inside the wall, facilitating the fixing of the support frame 1 to the side wall. The connecting plate and bolts are used to install the outer connecting device onto the support frame 1, and the attached lifting scaffold is connected by bolts. The protective uprights, horizontal bars, and protective plates of the protective device are installed on the long plate 4 by bolts. The limiting block 5 is located inside the support frame 1. By moving the handle 10 inside the fastening assembly 7, the fixing sleeve 9 is moved from inside the receiving groove 6 and through groove 3 out of the side wall of the support frame 1, and the fixing sleeve 9 is rotated from the horizontal direction to the vertical direction. Pulling the handle 10 allows the fixing sleeve 9 to move further inward. The side wall is attached to the outer side wall of the support frame 1. Tighten the nut 11 to restrict the movement of the threaded rod 8 and fix the long plate 4 and the protective device. By rotating the rotating plate 13, the rotating rod 12 is driven to rotate, which in turn drives the drive gear 14 to rotate. The teeth of the drive gear 14 mesh with the teeth of the toothed plate 15, which in turn drives the clamping plates 16 on both sides to move synchronously in opposite directions. This makes it easy to move the clamping plates 16 to be close to the upper surface of the long plate 4 and the lower surface of the support frame 1, clamping the support frame 1 and the long plate 4. Move the movable block 18 downward so that the bottom end of the movable block 18 moves between the two adjacent baffles 19, which can restrict the rotation of the rotating plate 13.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
