Description

Technical Field

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

[0002] Currently, scaffolding refers to various supports erected on construction sites to facilitate worker operations and solve vertical and horizontal transportation. In the construction industry, it refers to the use of scaffolding on construction sites for exterior walls, interior decoration, or in areas with high ceilings where direct construction is not possible. It is used to allow construction workers to move up and down, maintain external safety nets, and install components at height. During the assembly of scaffolding, necessary connectors are used to assemble multiple scaffold sections. A search revealed that patent application number 202020952784.9 discloses a scaffolding connection device for building construction, including a connection device for connecting vertical pipes and horizontal pipes. The connection device includes a vertical connector, a horizontal connector on one side of the vertical connector, and the horizontal connector and vertical connector are arranged crosswise. A first pin is provided between the horizontal connector and the vertical connector. The horizontal connector and the vertical connector are hinged through the first pin. An auxiliary support rod is provided on one side of the horizontal connector and abuts against the vertical pipe. In the vertical connector, one end of the first arc plate and the second arc plate are hinged through the second pin, and the other end is connected through the first bolt. A third arc plate is provided on the inner side of the first arc plate, and the third arc plate is slidably connected to the first arc plate.

[0003] However, in actual use, the applicant found that by setting a third arc plate inside the vertical connector and the horizontal connector, and by having the third arc plate abut against the vertical and horizontal pipes to connect the device to vertical and horizontal pipes of different diameters, the third arc plate cannot effectively contact the vertical and horizontal pipes of different diameters due to the fact that there is only one third arc plate inside the vertical connector and the horizontal connector, and it cannot be replaced. Therefore, the third arc plate cannot make effective contact with the vertical and horizontal pipes of different diameters over a large area, which makes the connection device not secure enough for fixing the vertical and horizontal pipes used for scaffolding. In view of this, we propose a construction scaffolding connection device. Utility Model Content

Detailed Implementation

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A construction scaffolding connection device includes a vertical connector 1, a horizontal connector 2, and a connecting seat 3 connecting the vertical connector 1 and the horizontal connector 2. The vertical connector 1 includes an outer support 4 and an inner support 5. The tail ends of the outer support 4 and the inner support 5 are rotatably connected by a hinge shaft 6. The front ends of both the outer support 4 and the inner support 5 are fixedly provided with connecting supports 8. The two connecting supports 8 are locked together by a first bolt 9 and a nut 10. The connecting supports 8 are symmetrically provided with fixing holes 81. One end of the first bolt 9 passes through the fixing holes 81 on the front connecting supports 8 of the outer support 4 and the inner support 5 in sequence, and is threadedly connected to the nut 10. The inner sidewalls of both the outer support 4 and the inner support 5 are fixedly connected by second bolts 11. The scaffold has a pipe seat 12, and connecting grooves 7 are provided on the inner sidewalls of the outer support 4 and the inner support 5. Connecting sliders 121 are symmetrically arranged on the inner sidewall of the pipe seat 12, and the connecting sliders 121 are connected to the connecting grooves 7. Through holes 14 are provided on the side of the outer support 4 and the inner support 5 away from the connecting support 8. Threaded holes 122 are provided on the sidewall of the pipe seat 12. One end of the second bolt 11 passes through the through hole 14 and is screwed into the threaded hole 122. The pipe seat 12 is detachably fixed on the inner sidewall of the outer support 4 and the inner support 5. The pipe seat 12 can make effective contact with the outer wall of the steel pipe used for scaffolding over a large area, achieving a more stable connection to the scaffolding. Furthermore, by replacing the pipe seat 12, the vertical... Connector 1 and pipe seat 12 are suitable for connecting steel pipes of different diameters, making them more practical. A rubber pad 13 is fixed to the outer wall of pipe seat 12. The horizontal connector 2 has the same structure as the vertical connector 1. During scaffolding erection, first, the vertical connector 1 is fastened onto the vertical steel pipe, ensuring that the rubber pad 13 on the outer wall of pipe seat 12 makes large-area effective contact with the outer wall of the vertical steel pipe. The outer support 4 and inner support 5 are then locked using the first bolt 9 and nut 10. Next, the horizontal connector 2 is fastened onto the horizontal steel pipe in the same way and locked using the first bolt 9 and nut 10. This achieves the connection between the vertical and horizontal steel pipes used in building construction scaffolding erection. When replacing the pipe seat 12, the pipe seat 12 can be replaced according to the diameter of the steel pipe, so that the rubber pad 13 on the outer wall of the pipe seat 12 can be in complete contact with the steel pipe. When replacing the pipe seat 12, one end of the second bolt 11 can be unscrewed from the threaded hole 122, and the pipe seat 12 can be slid out from the inner wall of the outer support 4 and the inner support 5. Then, the connecting slider 121 on the pipe seat 12 of the required model can be rotated and slid into the connecting groove 7. The pipe seat 12 can be installed on the inner wall of the outer support 4 and the inner support 5. Finally, the second bolt 11 can be screwed into the threaded hole 122 to lock the pipe seat 12. This completes the quick replacement of the pipe seat 12, so that the connecting device can be adapted to the connection of steel pipes used for scaffolding construction of different diameters.

[0022] A connecting ball groove 123 is provided on the outer wall of the tube seat 12. Several connecting ball grooves 123 are evenly distributed on the outer wall of the tube seat 12. A connecting ball head 131 is fixedly provided on the inner wall of the rubber pad 13. Several connecting ball heads 131 are evenly distributed on the inner wall of the rubber pad 13. The connecting ball head 131 and the connecting ball groove 123 are connected in cooperation. Through the provided connecting ball head 131 and connecting ball groove 123, it is convenient for personnel to replace the aged and damaged rubber pad 13, and the use effect is better. After a period of use, when the rubber pad 13 is aged or damaged, the old rubber pad 13 can be directly torn off from the outer wall of the tube seat 12. Then, the connecting ball head 131 on the new rubber pad 13 is aligned and inserted into the corresponding connecting ball groove 123 one by one, so that the new rubber pad 13 can be fixed on the tube seat 12, and the rubber pad 13 can be quickly replaced.

[0023] Working Principle: During use, when connecting scaffolding, first fasten the vertical connector 1 onto the vertical steel pipe, ensuring effective contact between the rubber pad 13 on the outer wall of the pipe seat 12 and the outer wall of the vertical steel pipe. Then, secure the outer support 4 and inner support 5 with the first bolt 9 and nut 10. Next, fasten the horizontal connector 2 onto the horizontal steel pipe in the same manner, securing it with the first bolt 9 and nut 10. This achieves the connection between the vertical and horizontal steel pipes used for building scaffolding. During use, the pipe seat 12 can be replaced according to the diameter of the steel pipe, ensuring complete contact between the rubber pad 13 on the outer wall of the pipe seat 12 and the steel pipe. When replacing the pipe seat 12, unscrew one end of the second bolt 11 from the threaded hole 122 and remove the pipe seat 12 from the outer support 4. Slide the tube seat 12 out onto the inner wall of the inner support 5, then rotate the connecting slider 121 on the required model of tube seat 12 and slide it into the connecting groove 7. Install the tube seat 12 on the inner wall of the outer support 4 and the inner support 5. Finally, screw the second bolt 11 into the threaded hole 122 to lock the tube seat 12. This completes the quick replacement of the tube seat 12, allowing the connecting device to be adapted to connect steel pipes used for scaffolding construction of different diameters. After a period of use, when the rubber pad 13 ages or is damaged, the old rubber pad 13 can be directly peeled off from the outer wall of the tube seat 12. Then, align the connecting ball head 131 on the new rubber pad 13 and insert it one by one into the corresponding connecting ball groove 123 to fix the new rubber pad 13 on the tube seat 12, thus completing the quick replacement of the rubber pad 13.
