Description

Technical Field

[0001] This utility model relates to the field of scaffolding, specifically to a pin-and-crossbar device for disc-lock scaffolding used in construction. Background Technology

[0002] In construction engineering, modular scaffolding is a key piece of equipment for the main structural construction. Modular scaffolding typically consists of a base, horizontal bars, and vertical bars. Whether in the construction of multi-story residential buildings or high-rise building frame structures and shear wall structures, it can serve as a formwork support system to fix the concrete pouring formwork, ensuring that floor slabs, beams, columns, and other components maintain their designed shape during pouring and preventing deformation of the concrete structure due to unstable support. Simultaneously, during the wall construction and interior / exterior finishing stages, modular scaffolding can be used to build working platforms, providing a safe and stable working space for construction workers. Its modular design allows for flexible adaptation to buildings with different floor heights and bay sizes, reducing the cost of adjusting the support system due to structural differences.

[0003] However, in existing technologies, the connection between the pins and the mounting holes of most disc-lock scaffolding relies entirely on the experience of construction workers during installation, which easily leads to misalignment and jamming, greatly delaying installation time, making it impossible to carry out subsequent work, and increasing project costs. As the requirements for standardization, efficiency, and safety of scaffolding in construction continue to increase, existing disc-lock scaffolding cannot meet project needs. Therefore, a horizontal bar device that can be installed quickly is required. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a pin-and-crossbar device for disc-lock scaffolding in construction, so as to solve the technical problem of low installation efficiency of disc-lock scaffolding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pin-type horizontal bar device for construction scaffolding, comprising a horizontal tube and a swivel-shaped plate, wherein joints are fixedly connected to both ends of the horizontal tube, a plate-holding groove for placing the swivel-shaped plate is formed at the middle of the joint, an inlet is formed at the top of the joint, an outlet is formed at the bottom of the joint, a pin is inserted into the inside of the joint, a positioning post is slidably connected to the bottom of the pin, the bottom of the positioning post is arc-shaped, a first sliding groove is formed on the side wall of the bottom of the pin, a limiting post is fixedly connected to the side wall of the positioning post, the limiting post is slidably connected in the first sliding groove, and a rivet is fixed on the side wall of the pin to prevent the pin from detaching from the joint.

[0006] By adopting the above technical solution, the plate slot provides an installation platform for the plum blossom plate. The inlet and outlet can be conveniently inserted into the connector with pins. The inlet and outlet can be regarded as two square holes of different sizes. The pins are used to fix the connector and the plum blossom plate. The positioning pin can be positioned to the hole opened on the plum blossom plate. The combination of the above structures can increase the installation speed and achieve a stable connection of the crossbar.

[0007] Furthermore, the plum blossom plate is provided with mounting holes for inserting pins.

[0008] By adopting the above technical solution, the mounting hole is used to cooperate with the pin to fix the connector and the plate.

[0009] Furthermore, an installation tube is fixedly connected to one end of the joint sidewall facing the horizontal tube, and the installation tube is fixed to the horizontal tube by press riveting.

[0010] By adopting the above technical solution, the installation pipe and the horizontal pipe are fixed by multiple press-fitting points, and the press-fitting points are evenly distributed.

[0011] Furthermore, the rivet can pass through the outlet, but the rivet cannot pass through the inlet.

[0012] By adopting the above technical solution, the pin is prevented from coming off in the connector.

[0013] Furthermore, the side of the tray groove away from the horizontal tube has a flared opening to facilitate the assembly of the plum blossom tray.

[0014] By adopting the above technical solution, the opening area of ​​the tray slot is increased, making it easier for the plum blossom tray to enter and enabling rapid installation.

[0015] Furthermore, the joints at both ends of the horizontal tube are symmetrically arranged along the longitudinal centerline of the horizontal tube.

[0016] By adopting the above technical solution, the fixing direction and angle of the two end joints are the same, because the plum blossom plate is generally set parallel to the horizontal plane, ensuring that the plum blossom plate can be installed normally at both end joints.

[0017] Furthermore, a second groove for rivet sliding is provided on the inner wall of the inlet.

[0018] By adopting the above technical solution, it is ensured that the pin has sufficient sliding stroke in the connector, so that the pin will not affect the installation of the plum blossom plate.

[0019] In summary, the present invention has the following main advantages: 1. This utility model achieves rapid positioning of the pin in the mounting hole through the cooperation of the positioning post and the first sliding groove, thereby enabling rapid installation of the connector and the plum blossom plate and improving installation efficiency. Through the cooperation of the rivet and the second sliding groove, it ensures that the pin will not fall out of the connector without affecting the installation of the plum blossom plate. While ensuring installation, the anti-detachment design of the pin reduces the number of operation steps for workers and further improves installation efficiency. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] In this example: A type of interlocking scaffolding pin-and-crossbar device for construction, such as Figure 1-5As shown, the device includes a horizontal tube 1 and a plum blossom plate 5. The horizontal tube 1 is fixedly connected to two connectors 2 at both ends. A groove 21 for placing the plum blossom plate 5 is provided in the middle of the connector 2, providing a platform for its installation. An inlet 22 is located at the top of the connector 2, and an outlet 23 is located at the bottom. The inlet 22 and outlet 23 can be considered as two square holes of different sizes, with the inlet 22 being smaller than the outlet 23. A pin 3, which is a wedge-shaped plate, is inserted into the inside of the connector 2 to fix the connector 2 and the plum blossom plate 5. A positioning post 6 is slidably connected to the bottom of the pin 3, and a slot is provided at the bottom of the pin 3 for positioning. The positioning post 6 is slidably connected in the slot. The bottom end of the positioning post 6 is arc-shaped to facilitate the entry of the plum blossom plate 5 into the plate placement slot 21. The bottom side wall of the pin 3 is provided with a first sliding groove 7, which communicates with the slot. A limiting post 8 is fixedly connected to the side wall of the positioning post 6. The limiting post 8 is used to fix the sliding stroke of the positioning post 6 and prevent the positioning post 6 from falling out of the slot. The limiting post 8 is slidably connected in the first sliding groove 7. A rivet 4 is fixed on the side wall of the pin 3 to prevent the pin 3 from falling out of the connector 2. When fixing the rivet 4, a hole for the rivet 4 needs to be opened on the side wall of the pin 3 first, then the pin 3 is inserted into the connector 2, and then the rivet 4 is fixed. See Figure 4 The plum blossom plate 5 has an installation hole 51 for inserting the pin 3. The installation hole 51 is used to cooperate with the pin 3 to fix the connector 2 and the plum blossom plate 5. See Figure 1 , Figure 2 An installation tube is fixedly connected to one end of the side wall of the connector 2 facing the horizontal tube 1. The installation tube and the horizontal tube 1 are fixed by riveting. The installation tube and the horizontal tube 1 are fixed by multiple riveting points, which are evenly distributed. See Figure 5 The rivet 4 can pass through the outlet 23, but cannot pass through the inlet 22, preventing the pin 3 from dislodging in the connector 2. See Figure 2 The tray groove 21 has an flared opening on the side away from the horizontal tube 1 to facilitate the assembly of the plum blossom tray 5, thereby increasing the opening area of ​​the tray groove 21, making it easier for the plum blossom tray 5 to enter and achieving rapid installation. See Figure 1 The connectors 2 at both ends of the horizontal tube 1 are symmetrically arranged along the longitudinal centerline of the horizontal tube 1 to ensure that the fixing direction and angle of the connectors 2 at both ends are the same. Since the plum blossom plate 5 is generally set parallel to the horizontal plane, it ensures that the plum blossom plate 5 can be installed normally at both ends of the connectors 2.

[0024] See Figure 5 The inner wall of the inlet 22 is provided with a second sliding groove 9 for the rivet 4 to slide, ensuring that the pin 3 has sufficient sliding stroke in the connector 2 and that the pin 3 will not affect the installation of the plum blossom plate 5. The implementation principle of this embodiment is as follows: Figure 4 As shown, the pin 3 is pulled upwards, and then the plum blossom plate 5 is inserted through the flared opening of the plate slot 21 away from the horizontal tube 1. When the plum blossom plate 5 slides inwards, the arc-shaped surface of the positioning post 6 slides upwards under the force of the plum blossom plate 5. When the positioning post 6 is above the mounting hole 51, the positioning post 6 will fall downwards due to gravity. At the same time as falling, it will make a metallic clanging sound, reminding the construction personnel that it has been installed in place. Even if the construction personnel do not hear it, at this time, the plum blossom plate 5 can no longer move in the plate slot 21 due to the influence of the positioning post 6, reminding the construction personnel that it has been aligned. Finally, the staff taps the top of the pin 3 to complete the fixing of the connector 2 and the plum blossom plate 5. It should be noted that in the actual test, the positioning effect of the positioning post 6 mainly plays the role of restricting the connector 2 from rotating around the center of the plum blossom plate 5.
