Description

Technical Field

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

[0002] The connection and fastening structure of a building scaffold is a component and fastening device (such as fasteners, bolts, nuts, etc.) that connects the various components of the scaffold (such as uprights and horizontal bars) into a whole. Its function is to transfer loads, maintain the shape of the structure, and ensure dynamic stability. The purpose of fastening design is to prevent safety accidents caused by connection failure, adapt to complex construction environments, meet the requirements of specifications, balance safety and economy, and ensure that the scaffold works reliably under various working conditions.

[0003] Most existing scaffolding connections use couplers, tightened with bolts, to secure the uprights, horizontal bars, and joints through friction. However, this reliance on friction for stability weakens the friction when the bolts loosen, significantly increasing safety risks. Furthermore, the fixed size of the scaffold base creates additional safety hazards as the scaffold height increases.

[0004] Therefore, those skilled in the art have provided a construction scaffolding connection and fastening structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a construction scaffolding connection and fastening structure. The structure is simple and easy to connect, with double-layer bolts to prevent loosening, and an external support for the base to prevent swaying.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A scaffolding connection and fastening structure includes two semi-circular tubes. A horizontal tube is fixedly installed at the center of the outer side of each semi-circular tube. Fixing rods are fixedly installed on the upper and lower sides of the inner ends of each semi-circular tube. A semi-circular rod is fixedly installed at the center of the inner ends of each semi-circular tube. Vertical tubes are movably sleeved on the upper and lower sides of the inner ends of each semi-circular tube. A No. 1 bolt is threaded onto the upper end of each horizontal tube near the semi-circular tube. A No. 2 bolt is threaded onto the center of the lower end of each No. 1 bolt. A support is fixedly installed at the lower end of one of the two vertical tubes. The base has six support plates fixedly and equidistantly on its upper outer side. Each of the six support plates has a No. 1 support rod rotatably mounted on its inner end. Each of the six No. 1 support rods has a rotating plate fixedly mounted on both its front and rear ends. Each of the twelve rotating plates has a No. 2 support rod fixedly mounted on the side away from the No. 1 support rod between each pair of rotating plates. Each of the twelve rotating plates has a No. 3 support rod fixedly mounted on the edge of the side away from the No. 2 support rod between each pair of rotating plates. Each of the six No. 2 support rods has a ground nail movably mounted on its outer end. Each of the six No. 3 support rods has a supporting foot rotatably mounted on its outer end.

[0008] Furthermore, both of the semicircular rods are movably disposed at the inner ends of the horizontal tube on opposite sides, and both of the No. 1 bolts are threaded onto the side of the semicircular rod away from the semicircular tube.

[0009] Furthermore, each of the two risers has two opposing semicircular holes on its opposite side, and each of the two risers has two opposing circular holes on its opposite side away from the semicircular holes.

[0010] Furthermore, the four fixed rods are movably disposed within the four circular holes, and the two semicircular rods are also movably disposed within the four semicircular holes.

[0011] Furthermore, the support base is fixedly installed at the lower end of the two semi-circular tubes, and the six ground nails are movably installed between each pair of the twelve rotating plates.

[0012] Furthermore, both the support base and the bottom end face of the support foot are designed with a rough texture.

[0013] This utility model has the following beneficial effects:

[0014] 1. The present invention proposes a construction scaffolding connection and fastening structure, which can achieve a stable connection of steel pipes by using components such as semi-circular tubes, semi-circular rods and fixing rods. The structure of adding semi-circular rods and fixing rods inside the semi-circular tubes, and after merging the two semi-circular tubes and tightening the bolts, the fixing rods can connect to the uprights and at the same time complete the connection of the horizontal tubes, thereby improving the stability of the scaffolding connection.

[0015] 2. This utility model proposes a scaffolding connection and fastening structure in which the threads of bolts #1 and #2 are designed in reverse. This reverse design ensures that after installation, when bolt #1 is tightened, bolt #2 contracts under force and tightens, while bolt #1 experiences a reaction force, making it impossible to loosen. Conversely, when bolt #2 is tightened, bolt #1 also experiences a tightening force and can be loosened. This design guarantees a more secure connection regardless of which bolt is tightened, and also clarifies that bolt #2 must be removed first during disassembly, improving the reliability and ease of operation of the scaffolding connection.

[0016] 3. The construction scaffolding connection and fastening structure proposed in this utility model has the following advantages: the addition of supports ensures that the stability of the scaffolding can be further improved after continuous accumulation and construction; the ground nails and the rotating plate form an "in" shaped structure, which greatly enhances the stability of the support; the ground nails are an integral structure on the support rods, which provides more points of contact for disassembly compared to ordinary ground nails, avoiding the trouble of disassembling ordinary ground nails; when not in use, the support frame around the base can be rotated upwards and fixed with ropes or other items, improving the overall stability and flexibility of the scaffolding.

[0025] 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.

[0026] Reference Figures 1 to 4 One embodiment provided by this utility model:

[0027] A construction scaffolding connection and fastening structure includes two semi-circular tubes 1. A horizontal tube 2 is fixedly installed at the center of the outer side of each of the two semi-circular tubes 1. A fixing rod 3 is fixedly installed on the upper and lower sides of the inner end of each of the two semi-circular tubes 1. A semi-circular rod 4 is fixedly installed at the center of the inner end of each of the two semi-circular tubes 1. A vertical tube 5 is movably sleeved on the upper and lower sides of the inner end of each of the two horizontal tubes 2. A No. 1 bolt 6 is threaded on the side of the upper end of each of the two horizontal tubes 2 near the semi-circular tubes 1. A No. 2 bolt 7 is threaded on the center of the lower end of each of the two No. 1 bolts 6.

[0028] Specifically, the size of the inner end hole of the horizontal tube 2 is adapted to the size of the semi-circular rod 4. During structural assembly, the semi-circular rod 4 enters the inner end of the horizontal tube 2, ensuring that the threaded hole on the semi-circular rod 4 is precisely aligned with the threaded hole of the horizontal tube 2, thus preventing jamming when tightening the No. 1 bolt 6. The threads of the No. 1 bolt 6 and the No. 2 bolt 7 are designed in opposite directions. This design ensures that when the No. 1 bolt 6 is tightened and the No. 2 bolt 7 is tightened, the No. 1 bolt 6 will not loosen; instead, it will make the connection more secure. When the No. 1 bolt 6 is tightened, the No. 2 bolt 7 contracts under force and tightens, providing a reaction force to the No. 1 bolt 6, making it impossible to loosen and improving the stability of the connection.

[0029] Reference Figure 5 , Figure 6 One of the two risers 5 has a support base 8 fixedly installed at its lower end. Six support plates 9 are fixedly installed at equal intervals on the outer side of the upper end of the support base 8. A first support rod 10 is rotatably installed at the inner end of each of the six support plates 9. Rotating plates 11 are fixedly installed at both the front and rear ends of the six first support rods 10. Second support rods 12 are fixedly installed on the side of each pair of rotating plates 11 away from the first support rod 10. Third support rods 13 are fixedly installed on the edge of each pair of rotating plates 11 away from the second support rod 12. Ground nails 14 are movably installed at the outer ends of the six second support rods 12. Support feet 15 are rotatably installed at the outer ends of the six third support rods 13.

[0030] Specifically, six support plates 9 are fixedly installed on the support base 8. This increases the stability of the support base 8 and allows for the installation of fixed brackets on top of it. The brackets are designed to be movable; when not in use, they can be rotated upwards and secured with ropes or other items. This design not only increases stability on flat ground but also adapts to concave environments. The ground stake 14 has a hollow design in the middle. It can not only move and function on the second support rod 12, but also, when the ground stake 14 is inserted into the soil, pressing the soil to force some soil into the ground stake 14 further enhances stability, improving the adaptability and stability of the device.

[0031] Reference Figures 1 to 6 Two semicircular rods 4 are movably mounted on the inner end of the horizontal tube 2 on opposite sides. Two No. 1 bolts 6 are threaded on the side of the semicircular rod 4 away from the semicircular tube 1. Two vertical tubes 5 have two opposite semicircular holes on opposite sides. Two vertical tubes 5 have two opposite round holes on opposite sides away from the semicircular holes. Four fixing rods 3 are movably mounted on the inner end of the four round holes. Two semicircular rods 4 are movably mounted on the inner end of the four semicircular holes. The support base 8 is fixedly mounted on the lower end of the two semicircular tubes 1. Six ground nails 14 are movably mounted between the twelve rotating plates 11. The bottom surfaces of the support base 8 and the support feet 15 are both roughened.

[0032] Specifically, the semi-circular rod 4 and the fixing rod 3 enter the hole of the vertical pipe 5, which not only fixes the upper and lower vertical pipes 5, but also fixes the height of the horizontal pipe 2, ensuring the stability and positional accuracy of the connection between the scaffold vertical pipe 5 and the horizontal pipe 2, and improving the overall structural strength.

[0033] Working principle: First, precisely align the two vertical pipes 5, then tightly fit the two semi-circular pipes 1 together. At this time, the fixing rod 3 and semi-circular rod 4 at the inner end of the semi-circular pipe 1 will be inserted into the preset hole of the vertical pipe 5 to form a preliminary positioning. After the two semi-circular pipes 1 are completely fitted together, screw the two No. 1 bolts 6 into the corresponding horizontal pipes 2 respectively, and then screw the two No. 2 bolts 7 into the No. 1 bolt 6. Through double tightening, the entire scaffolding is stably assembled. The disassembly process follows the reverse operation. Simply unscrew the No. 2 bolt 7 first, and then remove the No. 1 bolt 6 to easily disassemble. After the support base 8 at the bottom of the vertical pipe 5 is placed on the ground, pinch the support foot 15 and make it rotate around the No. 3 support rod 13. This action will drive the No. 3 support rod 13 to move together, thereby pulling the rotating plates 11 on both sides. At the same time, the No. 1 support rod 10 between the other ends of the two rotating plates 11 will rotate flexibly at the inner end of the support plate 9. Through this series of continuous transmission structures, the angle and position of the support foot 15 can be freely adjusted. Once the support legs 15 of all six supports are adjusted to the appropriate positions, rotate the ground nail 14. The ground nail 14 moves at the outer end of the second support rod 12, so that the tip of the ground nail 14 is aligned with the ground. Use a hammer to drive it into the ground, which can achieve secondary fixation of the scaffolding and further enhance the overall stability.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
