Description

Technical Field

[0001] This utility model belongs to the field of scaffolding technology, and in particular to a scaffolding node connection device. Background Technology

[0002] Scaffolding refers to various supporting structures erected on construction sites to facilitate worker operations and vertical and horizontal transportation. It's a common term in the construction industry, referring to scaffolding used on construction sites for exterior walls, interior decoration, or areas with high ceilings where direct construction is impossible. Its main functions include facilitating workers' movement up and down, providing safety netting, and installing components at heights. However, while current scaffolding connection nodes are designed with connectors, their positions are fixed, making it impossible to customize node connections at specific locations on the scaffolding.

[0003] A search revealed a Chinese patent document (authorization announcement number CN219316381U) regarding a scaffolding connection node for construction, comprising a node cylinder, a threaded seat installed on the side wall of the node cylinder, and a threaded bolt installed on the threaded seat. The surface of the threaded seat is provided with limiting teeth, and the side wall of the threaded bolt is symmetrically provided with sliding grooves. Limiting teeth are slidably installed within the sliding grooves, and a guide shaft is rotatably installed on the upper part of the limiting teeth. The guide shaft is inserted into a rectangular block, which is installed at the end of the sliding groove. A spring is sleeved on the guide shaft. The beneficial effect is that during the actual connection and installation of the scaffolding, the scaffolding is inserted into the node cylinder, and then the threaded bolt is tightened. During the tightening process, under the action of the spring and the limiting teeth, the limiting teeth move back and forth. After the threaded bolt is tightened, under the action of the spring, the limiting teeth are locked between the limiting teeth, preventing the threaded bolt from loosening and ensuring the stability of the scaffolding connection. The connection nodes of scaffolding are designed with connectors for connection, but their positions are fixed, and it is not possible to make node connections for specific positions on the scaffolding.

[0027] Please see Figures 1 to 3As shown, a scaffolding node connection device, in this embodiment, includes two V-shaped fixing plates 1 that fit over the outside of the scaffolding. One of the fixing plates 1 has two rows of threaded channels on its outer periphery. An assembly plate 2 is provided on one side of the fixing plate 1, and a V-shaped lower plate 3 is fixedly connected to the side of the assembly plate 2. The orientation of the fixing plate 1 and the orientation of the lower plate 3 are perpendicular to each other. An upper plate 4 of the same shape is provided above the lower plate 3 for connecting and fixing the scaffolding node. The two threaded channels are threadedly connected to fixing bolts 5. The side of the assembly plate 2 has a round hole for the fixing bolts 5 to pass through. The position of the assembly plate 2 is selected, and it is fixed with the fixing bolts 5. Then, the structure to be connected is placed, and the adjusting threaded rod 7 of the upper plate 4 is rotated so that the movable plate 8 and the lower plate 3 fix the structure to be connected. The clamping threaded rod 15 is rotated to clamp and fix it.

[0028] The dimensions of the fixed plate 1 and the corresponding lower plate 3 are selected according to actual needs to ensure that the fixing requirements are met. The movable plate 8 has a limited range of movement and can only be adapted to scaffolding within a certain size range.

[0029] Threaded tubes 6 are embedded in the top of the upper plate 4 and the side of the other fixed plate 1. The threaded tube 6 is threadedly connected to an adjusting threaded rod 7. The adjusting threaded rod 7 is rotatably connected to a movable plate 8 for clamping and fixing via a bearing. The side of the threaded tube 6 has a threaded hole, which is threadedly connected to a clamping threaded rod 15 for fixing the adjusting threaded rod 7. The fixed plate 1 is placed in the required position and orientation of the scaffold, and the adjusting threaded rod 7 is rotated so that the fixed plate 1 and the movable plate 8 cooperate to fix the scaffold at the designated position.

[0030] To improve the fixing effect, elastic rubber pads 9 are glued to the inner walls of the lower plate 3 and the movable plate 8, and anti-slip textures are formed on the outer periphery of the rubber pads 9.

[0031] For fixing, side connecting plates 10 are connected to both sides of the fixing plate 1, the lower plate 3 and the upper plate 4. The side connecting plates 10 have multiple round holes on their sides, and a combination bolt 11 with a nut is provided in two adjacent round holes.

[0032] To improve stability, both the lower clamping plate 3 and the upper clamping plate 4 are bolted to a first connecting plate 12. The first connecting plate 12 is connected to a second connecting plate 14 via a diagonal connecting plate 13. The side of the second connecting plate 14 has a round hole, and a fixing bolt 5 is also installed in the round hole. After the first connecting plate 12 and the second connecting plate 14 are installed, the first connecting plate 12, together with the diagonal connecting plate 13 and the second connecting plate 14, can improve the stability of the upper clamping plate 4 and the lower clamping plate 3 compared to the fixed clamping plate 1, thus improving the stability of the connection. If the mounting plate 2 is too high or too low, the part of the first connecting plate 12 that cannot be installed can be removed.

[0033] Working principle

[0034] This scaffolding node connection device involves placing the fixed clamping plate 1 in the required position and orientation on the scaffolding, rotating the adjusting threaded rod 7 to engage the fixed clamping plate 1 with the movable clamping plate 8, fixing the scaffolding at the designated position, selecting the position of the assembly plate 2, and fixing it with the fixing bolts 5. Then, the structure to be connected is placed, and the adjusting threaded rod 7 of the upper clamping plate 4 is rotated to fix the movable clamping plate 8 with the lower clamping plate 3 to the structure to be connected. The tightening threaded rod 15 is rotated to tighten and fix it. Then, the first connecting plate 12 and the second connecting plate 14 are installed. The first connecting plate 12, together with the inclined connecting plate 13 and the second connecting plate 14, can improve the stability of the upper clamping plate 4 and the lower clamping plate 3 compared to the fixed clamping plate 1, thereby improving the stability of the connection.
