Description

Technical Field

[0001] This invention relates to the field of auxiliary equipment technology for building construction, and specifically to a scaffolding system for construction. Background Technology

[0002] In the construction industry, scaffolding is widely used as a temporary support structure in various construction sites, providing a working platform for workers. Traditional scaffolding mainly relies on bolts, couplers, and other parts to connect and fix uprights, horizontal bars, and diagonal braces one by one. This connection method has significant drawbacks: the installation and dismantling process is cumbersome, highly dependent on the technical experience of the operators and the tools (such as wrenches), resulting in low overall erection efficiency. In addition, bolts and couplers are prone to damage, corrosion, or loss during repeated assembly and disassembly, increasing maintenance costs and safety risks.

[0003] Therefore, there is an urgent need in the field for a scaffolding system that can be quickly installed and dismantled, reliably connected, and reduces reliance on tools and skilled workers. Summary of the Invention

[0068] The first connecting component 5 and the side connecting component 3 are connected to the upright assembly 4 via a quick-locking mechanism that can be detachably inserted into the socket 411a.

[0069] Furthermore, in order to achieve rapid and accurate alignment and reliable mechanical locking between the uprights, thus ensuring the stability of the vertical load-bearing structure, the upright 41 includes the disc 411, and an upper upright 412 and a lower upright 413 fixedly disposed at both ends of the disc 411.

[0070] The upper upright 412 is provided with a plug-in part 414 at the end away from the disk 411;

[0071] The lower upright 413 and the plug-in part 414 are respectively provided with a through first connecting hole 413a and a second connecting hole 414a;

[0079] The protective mechanism 51 includes a horizontal tie rod 511, a left diagonal tie rod 512 and a right diagonal tie rod 513 arranged in a cross configuration;

[0081] The U-shaped diagonal lock head 515 has a first flat lock hole 515a on both sides that is through and corresponds to the insertion hole 411a of the disc 411.

[0082] The U-shaped opening of the U-shaped diagonal lock head is inserted into the disc 411, and is locked by inserting the first pin 516 into the first flat lock hole 515a and the insertion hole 411a.

[0083] In this embodiment, the use of a quick-locking scissor brace structure for protection enables integrated and rapid installation, greatly improving the overall rigidity and assembly efficiency of the unit.

[0084] Furthermore, a flat section 10 is provided at the intersection of the left diagonal tie rod 512 and the right diagonal tie rod 513, and the flat section 10 of the left diagonal tie rod 512 is in contact with the surface of the flat section 10 of the right diagonal tie rod 513.

[0085] In this embodiment, the flat cross design provides the necessary adjustment margin for the installation of the protective mechanism, reduces the manufacturing and assembly precision requirements, and enhances the system's fault tolerance and ease of installation.

[0086] Furthermore, in order to unify the connection method within the system, make the operation simple and intuitive, and ensure the consistency and reliability of the connection strength, the first connection mechanism 52 includes a first crossbar 521, and the two ends of the first crossbar 521 are provided with first U-shaped lock heads 523.

[0087] The first U-shaped lock head 523 has a second flat lock hole 523a that passes through and corresponds to the insertion hole 411a of the disc 411 on both sides;

[0088] The first U-shaped lock head 523 is inserted into the disc 411, and is locked by inserting the second pin 522 into the second flat lock hole 523a 411a.

[0089] Furthermore, the side connection assembly 3 includes a plurality of side connection mechanisms 31;

[0090] The side connection mechanism 31 includes a side crossbar 311, and the two ends of the side crossbar 311 are provided with second U-shaped lock heads 313;

[0092] The second U-shaped lock head 313 is inserted into the disc 411 and locked by inserting the third pin 312 into the third flat lock hole 313a and the insertion hole 411a.

[0093] Furthermore, to ensure the safety and reliability of all quick-lock connection points and prevent accidental loosening due to vibration or other reasons, the first pin 516 and the second pin 522 of the first connecting component 5, as well as the third pin 312 of the connecting component 3, are all flat pins that are wide at one end and narrow at the other, with their narrow ends fitting into the corresponding first flat lock hole 515a, second flat lock hole 523a, or third flat lock hole 313a.

[0094] Furthermore, in order to enable the scaffolding to adapt to uneven ground and ensure the stability of the entire system's foundation, each of the upright pole groups 4 is provided with an adjustable base 6 at its lowest point.

[0095] The adjustable base 6 is threadedly connected to the lower upright 413 of the lowest upright 41.

[0096] A method for installing a construction scaffolding system as described in any of the above claims includes the following steps:

[0097] S1: Assemble the pole assembly 4, connect multiple poles 41 sequentially through the plug and safety pin 42, and install the adjustable base 6 at the bottom;

[0098] S2: Construct scaffolding unit 100, place the assembled left and right upright groups 4 opposite each other, connect the left and right upright groups 4 through the first connecting component 5 to form front support component 1 or rear support component 2; then connect at least one side of front support component 1 and rear support component 2 through side connecting component 3 to form a stable scaffolding unit 100.

[0099] S3: The system expands by arranging multiple scaffolding units 100 horizontally and / or vertically. When arranged horizontally, adjacent scaffolding units 100 are connected by the first connecting component 5. When arranged vertically, the bottom of the uprights group 4 of the upper scaffolding unit 100 is connected to the top of the uprights group 4 of the lower scaffolding unit 100 by plugging and locking with safety pins 42, thus forming the required scaffolding system.

[0100] Assembly process of scaffolding system:

[0101] The present invention provides a scaffolding system for construction, the basic building module of which is scaffolding unit 100.

[0102] like Figure 1 and Figure 2 As shown, a complete scaffolding unit 100 mainly consists of a front support assembly 1, a rear support assembly 2, and a side connection assembly 3 connecting the two.

[0103] First, the assembly of pole assembly 4 is performed. For example... Figure 4 and Figure 5As shown, a single upright 41 integrates a disc 411, an upper upright 412, and a lower upright 413. The upper upright 412 has a connector 414 at its top. During assembly, the connector 414 of one upright 41 is inserted into the lower upright 413 of another upright 41, aligning the first connecting hole 413a on the lower upright 413 with the second connecting hole 414a on the connector 414. Then, a D-shaped safety pin 42 is inserted into the hole, achieving a reliable vertical connection between the uprights. This process is repeated until the upright assembly reaches the required height. In the upright assembly 4, the distance between the central axes of adjacent discs 411 is preferably 45cm; this standardized spacing facilitates the connection of other components. In addition to multiple circumferentially distributed connectors 411a on the disc 411, material-saving holes 411b are also provided between adjacent connectors 411a, effectively reducing the structural weight. Finally, screw the adjustable base 6 onto the bottom of the pole assembly 4 for leveling the system.

[0104] Next, scaffolding unit 100 is erected. Two assembled upright groups 4 are placed facing each other to form the framework of the support.

[0105] The first step is to install the first connecting component 5. The first connecting component 5 includes a protective mechanism 51 and a first connecting mechanism 52 located above and below it.

[0106] Install protective mechanism 51: such as Figure 3 and Figure 6 As shown, the protective mechanism 51 is a pre-assembled whole, including a horizontal tie rod 511, a left diagonal tie rod 512, and a right diagonal tie rod 513. During installation, first, the flat hooks 514 at the upper ends of the left and right diagonal tie rods 512 and 513 are hooked onto the corresponding insertion holes 411a of the upper layer of the left and right upright rod assemblies 4. Then, the U-shaped opening of the U-shaped diagonal lock head 515 at the lower end of the tie rod is inserted into the lower layer of the disc 411, aligning the first flat locking holes 515a on both sides of the lock head with the disc insertion holes 411a. Finally, the narrow end of the first pin 516 is inserted from top to bottom into the first flat locking holes 515a and the insertion holes 411a, while the wide end naturally locks against the outside of the lock head, achieving locking. The left and right diagonal tie rods 512 and 513 have flat positions 10 at their intersection areas, with the surfaces of the flat positions 10 of the two rods in contact. This design provides adjustment margin for installation.

[0107] Install the first connecting mechanism 52: (e.g.) Figure 7 As shown, the first connecting mechanism 52 includes a first crossbar 521, with first U-shaped lock heads 523 at both ends. During installation, the first U-shaped lock heads 523 are inserted into the discs 411 at corresponding heights of the left and right upright rod assemblies 4, so that the second flat locking holes 523a on both sides of the lock head are aligned with the disc insertion holes 411a, and then the second pins 522 are inserted to lock them in place.

[0108] Through the above steps, either the front support assembly 1 or the rear support assembly 2 is now complete. After assembling the other support assembly in the same way, connect the two using the side connection assembly 3. Figure 7 As shown, the side connection mechanism 31 includes a side crossbar 311, with second U-shaped lock heads 313 at both ends. During installation, the second U-shaped lock heads 313 are inserted into the discs 411 of the corresponding upright groups 4 of the front and rear support assemblies, aligning the third flat locking holes 313a on both sides of the lock head with the disc insertion holes 411a, and then the third pin 312 is inserted to lock it in place. Multiple layers of side connection mechanisms 31 are usually required to enhance stability. At this point, a stable scaffolding unit 100 is completed. (When only the scaffolding unit 100 is used, the side connection components 3 are installed on both sides of the scaffolding unit 100; when the scaffolding unit 100 is used as one end of the scaffolding system, only one side of the scaffolding unit 100 is equipped with the side connection components 3, which creates a passageway for workers to walk within the scaffolding system.)

[0109] Finally, system expansion is performed. For example... Figure 9 and Figure 10 As shown, the scaffolding unit 100 can be flexibly expanded according to construction needs.

[0110] Horizontal expansion: Multiple scaffolding units 100 are arranged horizontally, and the upright groups 4 of adjacent scaffolding units 100 are connected by the first connecting component 5 (specifically the first connecting mechanism 52).

[0111] Vertical expansion: The bottom of the uprights group 4 of the upper scaffolding unit 100 and the top of the uprights group 4 of the lower scaffolding unit 100 are locked together by plugging and safety pins 42 to achieve vertical stacking.

[0112] The first pin 516, the second pin 522, and the third pin 312 described in this invention are all flat pins that are wide at one end and narrow at the other, with their narrow ends precisely fitting the corresponding flat lock holes. The disassembly process is the reverse of the installation process, making it simple and quick.

[0113] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this invention.
