[0028] Prefabricated scaffolding base plate, including base plate 1, the bottom surface of base plate 1 is in contact with the ground, four support legs 2 of the scaffolding are movably installed on the top surface of base plate 1, a device groove 3 is opened on base plate 1, a servo motor 4 is installed in device groove 3, the output shaft of servo motor 4 is connected with a transmission gear 5, two internal gears 6 and external gears 7 are respectively meshed on both sides of transmission gear 5, a first forward and reverse lead screw 8 and a second forward and reverse lead screw 9 are respectively installed on internal gear 6 and external gear 7, two internal clamping rods 10 are threadedly connected on first forward and reverse lead screw 8, two external clamping rods 11 are threadedly connected on second forward and reverse lead screw 9, and two support legs 2 are clamped between every two adjacent internal clamping rods 10 and external clamping rods 11.

[0029] By placing the scaffolding on base plate 1, the four support legs 2 of the scaffolding are located at the top of base plate 1. Then, servo motor 4 is turned on. The rotation of servo motor 4 causes the transmission gear 5 connected thereto to rotate synchronously, thereby driving the internal gear 6 and external gear 7 meshed with transmission gear 5 to rotate in opposite directions along each other, thereby driving the first forward and reverse lead screw 8 and the second forward and reverse lead screw 9 to rotate simultaneously. Furthermore, the two internal clamping rods 10 threadedly connected on the first forward and reverse lead screw 8 move away from each other, and the two external clamping rods 11 threadedly connected on the second forward and reverse lead screw 9 move closer to each other, so that the two support legs 2 between every two adjacent internal clamping rods 10 and external clamping rods 11 are clamped, thus achieving the purpose of installing the scaffolding on base plate 1. This installation method is simple to operate and firmly installed. It can meet the installation requirements of the scaffolding at different positions by moving base plate 1, avoiding the work of repeatedly pouring and removing concrete in the conventional installation of the scaffolding, greatly improving the construction efficiency and saving the construction cost.

[0030] Specifically, in this embodiment, a connecting plate 12 is installed on the bottom wall surface of device groove 3, a connecting hole 13 is opened on connecting plate 12, and the center points of connecting hole 13, transmission gear 5, and servo motor 4 are on the same axis.

[0031] Through the setting of connecting plate 12, servo motor 4 can be installed on connecting plate 12, and its output shaft can pass through connecting plate 12 through connecting hole 13 and be connected with transmission gear 5, thereby realizing the normal operation of transmission gear 5.

[0032] Specifically, in this embodiment, the two internal clamping rods 10 are inside the two external clamping rods 11, the distances from the two internal clamping rods 10 to the adjacent external clamping rods 11 are the same, and the distances from every two adjacent internal clamping rods 10 and external clamping rods 11 to the closest support leg 2 are the same.

[0033] By controlling the distances between the two internal clamping rods 10, the two external clamping rods 11 and the support legs 2, the internal clamping rods 10 and the external clamping rods 11 can contact the support legs 2 simultaneously when moving, so as to achieve the purpose of fixing the scaffolding by the internal clamping rods 10 and the external clamping rods 11.

[0034] Specifically, in this embodiment, clamping blocks 14 are installed at both ends of the two inner clamping rods 10 and the two outer clamping rods 11. Every two adjacent clamping blocks 14 are arranged oppositely, and arc-shaped openings are formed at their mutually approaching ends.

[0035] Through the arrangement of the clamping blocks 14, when the inner clamping rods 10 and the outer clamping rods 11 move, they can drive two adjacent clamping blocks 14 to approach the support legs 2, and clamp the support legs 2 through the arc-shaped openings on the clamping blocks 14, so as to achieve the purpose of fixing each support leg 2 and further improve the installation stability of the scaffolding.

[0036] Specifically, in this embodiment, rubber pads 15 are slidably installed on the arc-shaped openings of several clamping blocks 14. A convex block 16 is installed at one end of the rubber pad 15 close to the clamping block 14, and a groove 17 is formed on the clamping block 14. The convex block 16 is slidably fitted in the groove 17.

[0037] Through the arrangement of the rubber pads 15, when the clamping blocks 14 clamp the support legs 2, the rubber pads 15 slidably installed on them first come into contact with the support legs 2, thereby increasing the friction between the clamping blocks 14 and the support legs 2, making the fixing of the clamping blocks 14 on the support legs 2 more firm. At the same time, when the rubber pads 15 are damaged, they can be replaced through the adaptability of the convex blocks 16 and the grooves 17, improving the practicability of the clamping blocks 14.

[0038] Specifically, in this embodiment, a first connecting member 18 and a second connecting member 19 are respectively installed on the lower wall surfaces of the connecting members of the two inner clamping rods 10 and the two outer clamping rods 11. The first connecting member 18 is adapted to the first positive and negative screw rod 8, and the second connecting member 19 is adapted to the second positive and negative screw rod 9.

[0039] Through the arrangement of the first connecting member 18 and the second connecting member 19, the inner clamping rods 10 and the outer clamping rods 11 can be respectively threadedly installed on the first positive and negative screw rod 8 and the second positive and negative screw rod 9, so as to drive the inner clamping rods 10 and the outer clamping rods 11 to move by rotating the first positive and negative screw rod 8 and the second positive and negative screw rod 9.

[0040] Specifically, in this embodiment, a moving groove 20 is formed on the base plate 1. The moving groove 20 is communicated with the device groove 3, and the width of the moving groove 20 is greater than the width of the second connecting member 19, and its length is longer than the distance between the two support legs 2 with a smaller distance.

[0041] Through the arrangement of the moving groove 20, the second connecting member 19 can move outside the support leg 2 adjacent to it, thereby driving the two outer clamping rods 11 to move towards the support leg 2, and thus completing the clamping of the outer clamping rods 11 and the support legs 2.

[0042] Specifically, in this embodiment, four embedding grooves 21 are formed at the top of the backing plate 1. Each embedding groove 21 is located in the middle of two oppositely arranged clamping blocks 14, and each embedding groove 21 is adapted to a plurality of support legs 2.

[0043] Through the arrangement of the embedding grooves 21, the four support legs 2 of the scaffolding can be inserted into the corresponding embedding grooves 21, thereby strengthening the connection between the support legs 2 and the backing plate 1 and improving the stability of the connection between the support legs 2 and the backing plate 1.

[0044] Specifically, in this embodiment, lug ears 22 are installed at the four corners of the backing plate 1. Through holes 23 are formed in a plurality of lug ears 22, and bolts 24 are threadedly installed in a plurality of through holes 23.

[0045] Through the arrangement of the lug ears 22, the through holes 23 and the bolts 24, the backing plate 1 can be installed on the ground by connecting the bolts 24 to the ground, thereby increasing the stability of the connection between the backing plate 1 and the ground.

[0046] Specifically, in this embodiment, a plurality of barbs 25 are installed on the backing plate 1. The plurality of barbs 25 are obliquely installed on the bottom wall surface of the backing plate 1, and the lengths of the plurality of barbs 25 are longer than the thickness of the backing plate 1.

[0047] Through the arrangement of the plurality of barbs 25, when the backing plate 1 is installed on the ground, the barbs 25 will be embedded in the soil body, thereby increasing the connection strength between the backing plate 1 and the ground.

[0048] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
