In this embodiment, an "I"-shaped scaffolding support base 1-1 is symmetrically arranged on both the left and right sides, and an X-shaped bracket base 7 is arranged in the middle of the two scaffolding support bases 1-1;

[0033] While the X-shaped bracket base 7 supports and rotates the X-shaped bracket 8, it can also play a role in partially supporting the upper scaffolding.

[0034] Further, the middle X-shaped bracket base 7 is connected to the scaffolding support bases 11 on both sides through the rotating X-shaped bracket 8. The curved surface groove of the "I"-shaped scaffolding support base 1-1 is similar in volume to the X-shaped bracket base 7.

[0035] The middle X-shaped bracket base is connected to the scaffolding support bases 1-1 on both sides through the rotating X-shaped bracket 8, facilitating the fixing device and the folding device.

[0036] Further, each of the scaffolding support bases 1-1 on both sides is provided with a socket for a tensioning bolt.

[0039] A tensioning bolt is provided at the central position of the X-shaped bracket 8 and the X-shaped bracket base 7, facilitating the rotation of the X-shaped bracket 8 and the adjustment of the angle, and also facilitating the later disassembly and maintenance. A tensioning bolt is provided at the connection between the X-shaped bracket 8 and the scaffolding support bases 1-1 on both sides, facilitating the adjustment of the connection position to achieve the purpose of adjusting the distance between the scaffolding support bases 1-1 on both sides, and also facilitating the later disassembly and maintenance.

[0040] Further, each of the bottom surfaces of the scaffolding support bases 1-1 on both sides and the bottom surface of the middle X-shaped bracket base 7 is provided with a brake universal wheel 4.

[0041] Three brake universal wheels 4 are provided on the bottom surface of each of the scaffolding support bases 1-1 on both sides, and two brake universal wheels 4 are provided on the bottom surface of the X-shaped bracket base 7, facilitating the movement of the device.

[0042] Further, each of the scaffolding support bases 1-1 on both sides is provided with screw holes 5. Six screw holes 5 are provided on one side, and four threaded steel bars 3 are inserted tightly into the screw holes 5 at four different positions of the base.

[0045] In this embodiment, there are few products related to the rapid scaffolding assembly device, and most of them are immovable, non-foldable, non-detachable, and cannot be used as a single scaffolding body installation piece; compared with this device, it has higher practical value. The device is movable, fixable, foldable, easy to place, reduces space occupation, and can adjust different lengths, widths and heights between vertical pipes to meet the use of scaffolding platforms with different vertical rod spacings. Different from other common rapid scaffolding assembly devices, in the actual use process, this device does not need to additionally install a finished scaffolding frame piece on the device, and the support base of the device can be used as a finished scaffolding frame piece. If a finished scaffolding frame piece is used, the finished scaffolding frame piece can also be fixed on the device in cooperation with the vertical pipes on the device; in addition, the device has a simple structure, high strength, safety and reliability. While meeting the support strength and the functions, the support base of the device adopts an "I"-shaped scaffolding support base 1-1, and has a large area of hollow positions, which greatly reduces the weight of the device. It is more convenient for construction workers to move the device, reducing the workload; it is also relatively easy to actually manufacture this device, the materials are simple and common, the cost is low, and it is easy to use. In addition, the overall structure can be disassembled and installed, which is convenient for later maintenance and extends the service life.

[0046] Specifically:

[0047] Such as Figures 1-4 shown, this embodiment includes a scaffolding support assembly and a bracket assembly.

[0048] The scaffolding support assembly is mainly composed of two axially symmetric scaffolding support bases, including the scaffolding support base 1-1. The two scaffolding support bases 1-1 on both sides are in an "I" shape. Four symmetrical threaded steel bars 3 are installed on the scaffolding support base 1-1. Hollow steel pipes 2 are installed on the threaded steel bars 3. There are screw holes 5, bolt punching holes 6, and folding notches 12 on the scaffolding support base 1-1. A universal wheel 4 with a brake is installed on the bottom surface of the scaffolding support base 1-1.

[0049] The bracket assembly is mainly composed of an X-shaped bracket base 7, an X-shaped bracket 8 and a bolt 9.

[0050] Furthermore, the threaded steel bars 3 are installed on the scaffolding support base 1-1 through the screw holes 5, and the height can be appropriately adjusted according to needs. At the same time, they can be installed in different screw holes 5, and the distance between the two threaded steel bars 3 can be adjusted according to the actual spacing of the scaffolding vertical rods. The threaded steel bars 3 have high strength and are convenient for installation and disassembly.

[0051] Furthermore, a hollow steel pipe 2 is installed on the ribbed steel bar 3. The scaffold support base 1-1 not only plays the role of supporting the scaffold body, but also can be used as a finished scaffold body piece and is more reliable. The height of the hollow steel pipe 2 can be appropriately adjusted according to needs to cooperate with the additionally installed finished scaffold body pieces. The ribbed steel bar 3 and the hollow steel pipe 2 together form the bottom columns of the finished scaffold body, and the distance can be adjusted with the ribbed steel bar 3 to meet the needs of scaffolds with different vertical bar spacings. The space steel pipe 3 has high strength and is convenient for disassembly and installation.

[0052] Furthermore, in order to reduce the weight of the device, the scaffold support bases 1-1 on both sides are of "I"-shaped structure and have a large area of hollow space.

[0053] Brake universal wheels 4 are installed on the bottom surface of the scaffold support base 1-1. Three brake universal wheels 4 arranged in a straight line are installed at the bottom of each of the scaffold support bases 1-1 on both sides to meet the upper support pressure strength.

[0054] The brake universal wheels 4 facilitate the movement of the device and can be fixed during construction, which can stabilize the scaffold body and ensure the safety of construction workers.

[0055] Furthermore, the X-shaped bracket 8 and the X-shaped bracket base 7 are connected by bolt 1 9. Bolt 1 9 is a detachable bolt with threads, which is convenient for the X-shaped bracket 8 and the X-shaped bracket base 7 to be disassembled and separated, and is easy to maintain.

[0056] The X-shaped bracket 8 can be rotated up and down by a certain angle to achieve the purpose of different distances between the scaffold support bases 1-1 on both sides and being easy to fold and convenient for folding.

[0057] Two brake universal wheels 4 are installed on the bottom surface of the X-shaped bracket base 7, which is convenient for movement and fixation.

[0058] Furthermore, a plurality of bolt holes 6 are provided on the scaffold support base 1-1. The X-shaped bracket 8 and the scaffold support base 1-1 are connected by bolt 2 10 through the bracket connection hole 11. Bolt 2 10 is inserted into the bolt hole 6, and bolt 2 10 is a detachable threaded bolt, which is convenient for disassembling and separating the scaffold support base 1-1 and the bracket assembly.

[0059] Furthermore, folding notches 12 are provided on the symmetric scaffold support bases 1-1 on both sides. The shape of the folding notch 12 is similar to that of the X-shaped bracket base 7. After the device is used, the X-shaped bracket base 7 can be retracted into the folding notch 12, or each part of the assembly can be disassembled and placed separately, which greatly reduces the occupied space volume.

[0060] Embodiment 2. As Figures 5-7As shown, a rapid assembly device for a movable and foldable scaffolding according to the present invention includes a scaffolding support assembly and a bracket assembly. The scaffolding support assembly mainly consists of two axially symmetric scaffolding support base devices.

[0061] The scaffolding support base device includes two scaffolding support bases II 1 on both sides, and the two scaffolding support bases II 1 on both sides are semi-closed hollow structures.

[0062] Four symmetric threaded steel bars 3 are installed on the scaffolding support base II 1.

[0063] A hollow steel pipe 2 is installed on the threaded steel bar 3.

[0064] A screw hole 5, a bolt punching hole 6 and an overlapping groove 12 are provided on the scaffolding support base II 1.

[0065] A brake universal wheel 4 is installed on the bottom surface of the scaffolding support base II 1.

[0066] Furthermore, the bracket assembly mainly consists of an X-shaped bracket base 7, an X-shaped bracket 8 and a bolt I 9.

[0067] Furthermore, the threaded steel bar 3 is installed on the scaffolding support base II 1 through the screw hole 5, and the height can be adjusted appropriately according to needs. At the same time, it can be installed in different screw holes 5, so that the distance between the two threaded steel bars 3 can be adjusted according to the actual distance between the vertical poles of the scaffolding. The threaded steel bar 3 has high strength and is convenient for installation and disassembly.

[0068] Furthermore, a hollow steel pipe 2 is installed on the threaded steel bar 3. The scaffolding support base II 1 not only plays a role in supporting the scaffolding body, but also can be used as a finished scaffolding body piece and is more reliable. The hollow steel pipe 2 can be adjusted appropriately in height according to needs to cooperate with the additionally installed finished scaffolding body pieces.

[0069] The threaded steel bar 3 and the hollow steel pipe 2 together form the bottom columns of the finished scaffolding body, and the distance can be adjusted with the threaded steel bar 3 to meet the needs of scaffolding with different vertical pole distances. Among them, the space steel pipe 2 has high strength and is convenient for disassembly and installation.

[0070] Furthermore, in order to greatly reduce the weight of the device, the two scaffolding support bases II 1 on both sides are both semi-closed hollow structures. A brake universal wheel 4 is installed on the bottom surface of the scaffolding support base II 1, and three linearly arranged brake universal wheels 4 are installed at the bottom of each of the two scaffolding support bases II 1 on both sides to meet the upper support pressure strength.

[0071] The brake universal wheel 4 is convenient for moving the device and can be fixed during construction, which can stabilize the scaffolding body and ensure the safety of construction workers.

[0072] Furthermore, the X-shaped bracket 8 and the X-shaped bracket base 7 are connected by a first bolt 9, and the first bolt 9 is a detachable bolt with threads, which facilitates the disassembly and separation of the X-shaped bracket 8 and the X-shaped bracket base 7 and is easy to maintain;

[0073] The X-shaped bracket 8 can rotate up and down by a certain angle, so as to achieve the purpose that the distances between the two scaffolding support bases 1 on both sides are different and it is easy to fold for folding;

[0074] Two brake universal wheels 4 are installed on the bottom surface of the X-shaped bracket base 7, which facilitates movement and fixation.

[0075] Furthermore, there are multiple bolt holes 6 on the scaffolding support base 1. The X-shaped bracket 8 and the scaffolding support base 1 are connected by a second bolt 10 through a bracket connection hole 11. The second bolt 10 is inserted into the bolt hole 6, and the second bolt 10 is a detachable threaded bolt, which facilitates the disassembly and separation of the scaffolding support base 1 and the bracket assembly;

[0076] There is a rectangular opening larger than the bolt hole 6 beside the bolt hole 6. On the premise of meeting the strength, the weight is reduced by a part, and this rectangular opening is not used as the connection port between the X-shaped bracket 8 and the scaffolding support base 1.

[0077] Furthermore, on the symmetric scaffolding support bases 1 on both sides, there are folding notches 12. The shapes and sizes of the folding notches 12 are similar and slightly larger than the X-shaped bracket base 7. After the device is used, the X-shaped bracket base 7 can be better retracted into the folding notch 12, or each part of the component can be disassembled and placed separately, which greatly reduces the occupied space volume.

[0078] The above is only the preferred implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
