[0002] The disc-lock scaffolding system is a new type of construction scaffolding system, widely used in modern construction due to its unique structural design and connection method. The conventional disc-lock scaffolding construction method involves using two parallel grooves as the main material, bolted together to form an integrated device, which is then placed on a tray on the scaffolding uprights. The disadvantages of this existing technology are: the device is heavy and difficult to install. Conventional double-groove support beams are quite heavy, often requiring cranes and manual labor for installation. Furthermore, the double-groove support beams are typically installed at the bottom of beams, making the installation of heavy objects at height even more challenging. Therefore, there is a need to design a convenient, lightweight, and standardized disc-lock scaffolding double-groove support beam and its construction method. Utility Model Content

However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0019] Example 1:

[0020] like Figure 1As shown, a lightweight, standardized disc-lock frame double-groove support beam device includes a disc-lock frame upright 1, square steel bars 2, and an automatic locking pin 3. Side trays 1.1 are provided on both sides of the disc-lock frame upright 1. Two square steel bars 2 are mounted on the side trays 1.1 on both sides of several disc-lock frame uprights 1. The automatic locking pin 3 automatically engages with the two square steel bars 2, fixing them to both sides of the disc-lock frame upright 1. This design reduces the device's weight and installation difficulty.

[0021] In this embodiment of the utility model, such as Figure 2 As shown, square steel 2 has through holes 2.1. The through holes 2.1 on two square steel 2 are aligned in a straight line. The automatic locking pin 3 passes through the through holes 2.1 on both square steel 2 and engages. There are two square steels, each with dimensions of 40×60×2mm. They come in two lengths, 1.4m and 1.7m, to accommodate different pole spacing under various support conditions. Two φ18mm round holes are provided on the side of the square steel, the position of which depends on the length of the square steel.

[0022] In this embodiment of the utility model, such as Figure 3-4 As shown, the automatic locking pin 3 includes a main rod 3.1, a pin piece 3.2, a pin 3.3, and a vertical rod 3.4. The vertical rod 3.4 is located at one end of the main rod 3.1, and the pin piece 3.2 is located at the other end of the main rod 3.1 via the pin 3.3. The pin piece 3.2 can be rotated 90° to one side. The pin piece 3.2 is a trapezoidal pin piece, which enables automatic locking. The pin shaft includes a main rod, a trapezoidal pin piece, and two pins. The main rod is made of φ16mm round steel and has an L-shaped structure with a grooved end on the long side. The trapezoidal pin piece is connected to the grooved end via the pin.

[0023] In this embodiment of the utility model, the end of the main rod 3.1 is provided with a groove 3.5, the pin 3.2 is disposed in the groove 3.5, the pin 3.3 passes through the pin 3.2 and is connected to the groove 3.5, and can be rotated to one side, but cannot be rotated to the other side.

[0024] In this embodiment of the invention, the bottom of the groove 3.5 is set as an inclined groove bottom 3.6, and one end of the pin 3.2 is provided with an inclined surface structure, which is matched with the inclined groove bottom 3.6. The device is lightweight, requires no mechanical assistance, and can be installed manually. The installation is simple and easy. The device is modular, simple and efficient to install, and has high strength, allowing for a high number of reuses.

[0025] The construction process of the double-groove support beam device is as follows:

[0026] Step 1: Place two square steel bars 2 on the side trays 1.1 on both sides of the upright pole 1 of the disc buckle frame, with the perforations 2.1 of the square steel bars 2 corresponding to each other;

[0027] Step 2: Make the long side of the pin 3 horizontal and the short side upward. The pin piece 3.2 at the end of the long side will automatically hide in the groove 3.5 under the action of gravity.

[0028] Step 3: Pass the long side of pin 3 through the through holes 2.1 of the two square steel bars, and rotate it 180° so that pin 3.2 becomes vertical under the action of gravity. This connects and fixes the two square steel bars 2, making them ready for use.

[0029] Step 4: After use, rotate the pin 3 180° so that the pin 2 will automatically hide in the groove 3.5 under the action of gravity, and then the pin 3 can be pulled out.

[0030] Step 5: Remove square steel 2; it can be reused.

[0031] Example 2:

[0032] This embodiment differs from Embodiment 1 in the structure of the pin 3.2 and the groove 3.5. By setting the end of the groove 3.5 to an arc shape (specific drawing not shown), and simultaneously setting the bottom of the groove 3.5 to an arc shape, rotation under gravity can still be achieved. The groove 3.5 is designed with a hollowed-out side and a structural hole on the other side. The pin 3.3 passes through the side of the groove 3.5 and is positioned at one end of the pin 3.2. The inner end of the pin 3.2 is set to an arc structure, and the pin 3.2 can be rotated toward the hollowed-out side of the groove 3.5.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
