Detailed Implementation

[0018] like Figure 1-3 In this paper, an easily expandable prefabricated scaffold includes multiple parallel support frames 1. The upper sides of two adjacent support frames 1 are connected by multiple footboards 2. The bottom of the support frame 1 is detachably provided with an adjusting brace 5 and a heightening component 8. The adjusting brace 5 and the heightening component 8 cooperate to support the whole on the working surface. The heightening component 8 is located between the support frame 1 and the adjusting brace 5. The top of the support frame 1 is also provided with a railing assembly 6. The railing assembly 6 is connected by the support frame 1 and the footboards 2 to form a working area.

[0019] like Figure 11-12In this solution, the scaffolding can be expanded along the laying direction of the support frame 1 according to the needs of use, thereby meeting the requirements of use. Due to different construction scenarios, traditional scaffolding has a fixed size and is relatively large, making it unsuitable for working in relatively narrow spaces. It also cannot adapt to working in scenarios with different support surfaces, such as completing support on stairwells with staggered steps, thus limiting the working area covered by the scaffolding and causing many inconveniences. By adjusting the support 5 and the heightening component 8, various scenarios with different support heights can be completed, ensuring the overall support stability while keeping the tread 2 in a relatively straight state, thus facilitating construction workers to complete high-altitude operations smoothly and safely. The support frame 1 is modularly set up, and this solution is easy to install and dismantle, ensuring safe and efficient construction.

[0020] like Figure 9-10 In the preferred embodiment, the support frame 1 includes two vertical tubes 101 arranged opposite to each other, the heightening component 8 includes a sleeve 801 and an extension rod 805, the extension rod 805 is inserted into the vertical tube 101, and the adjusting support 5 is threadedly connected to the vertical tube 101 and the sleeve 801 respectively.

[0021] The vertical tube 101 is made of tubular material, which ensures its own structural stability and strength while having a low weight. It is easy to install, disassemble and move, and convenient to use. Adjustable supports 5 can be installed on different support frames 1 as needed. At the same time, in order to ensure a larger adjustment range, the heightening component 8 increases the support height of the support frame 1, making it simple to use and more effective.

[0022] In a preferred embodiment, a plurality of first through holes 103 and fourth through holes 802 are respectively provided on the lower side of the vertical tube 101 and the extension rod 805, and the insertion rod 803 passes through the first through holes 103 and the fourth through holes 802.

[0023] By using different first through holes 103 and fourth through holes 802, the position of the extension rod 805 can be flexibly changed, thereby changing the height adjustment range of the support frame 1 to adapt to different scenario needs.

[0024] like Figure 4-6 In the preferred embodiment, the interior of the vertical tube 101 and the sleeve 801 are respectively provided with a first threaded hole 104 and a second threaded hole 804, and the adjusting support 5 includes a vertical rod 501, which is located inside the first threaded hole 104 and the second threaded hole 804.

[0025] The adjusting brace 5 increases the contact area between the vertical tube 101 and the supporting surface, resulting in high overall safety and good support effect. It adopts a threaded connection, which allows for continuous and stable height adjustment.

[0026] In a preferred embodiment, the lower part of the upright 501 is connected to a ball head 503 via a transition rod 502, and a contact pad 504 is hinged to the lower part of the ball head 503. A gripping rod 505 is also provided on the outer side of the upright 501.

[0027] The contact pad 505 and the column 501 are connected by a ball joint, which can adapt to the unevenness of the working surface and provide better support. When in use, the construction personnel can rotate the rod 505 by holding it, which allows for flexible rotation without the need for external tools.

[0028] In the preferred embodiment, the support frame 1 includes a plurality of parallel horizontal tubes 102, and the pedal 2 includes a load-bearing part 201. Two hooks 202 are symmetrically provided on both sides of the load-bearing part 201, and the hooks 202 are engaged with the uppermost horizontal tube 102.

[0029] A gap is provided between the load-bearing part 201 and the hook 202, so that when the scaffolding needs to be extended, the two adjacent steps 2 can avoid each other and prevent the two steps 2 from obstructing each other along the extension direction.

[0030] In the preferred embodiment, the outer sides of two adjacent support frames 1 are connected by two staggered diagonal braces 3. The diagonal braces 3 are fixed to the support frame 1 by fixing clips 4. The fixing clips 4 are detachably mounted on the support frame 1.

[0031] In use, the diagonal braces 3 enhance the overall structural strength and rigidity of the scaffold. At the same time, since the two diagonal braces 3 on the same side of the support frame 1 are independent of each other and are respectively set on opposite sides of the vertical pipe 101, it ensures that when expansion is required, the first screw 404 has a stable installation point, ensuring convenient installation.

[0032] In the preferred embodiment, the diagonal brace 3 has protrusions 301 on both sides, and a second through hole 302 is provided through the protrusions 301. The fixing clamp 4 includes two semi-ring clamps 401 arranged opposite to each other. A first screw 404 is provided on the outside of the semi-ring clamps 401, and the first screw 404 passes through the second through hole 302.

[0033] During installation, the two diagonal braces 3 are first installed onto the fixing clamps 4, and then the fixing clamps 4 are fixed. The installation is convenient and the adjustment range is large. The two sides of the semi-ring clamps 401 are respectively provided with first ear plates 402. Screws 403 are passed through the two opposite first ear plates 402. The screws 403 are fixed to the two semi-ring clamps 401 by nuts 7. At the same time, a rubber layer 405 is provided on the inner side of the semi-ring clamps 401 to increase the friction. When the two ring clamps 401 are attached to the outside of the vertical pipe 101, the vertical pipe 101 is fixed by the contact and buffer of the rubber layer 405, with the cooperation of screws 403 and nuts 7. The diagonal braces 3 can be fixed to the first screw 404 by nuts 7. By adjusting the position of the fixing clamps 4, the force support point of the overall diagonal braces 3 is adjusted, which can adapt to the needs of support frames 1 of different heights, ensure the overall force balance, strong load-bearing capacity, and provide safety for construction personnel.

[0034] like Figure 7-8 In a preferred embodiment, the railing assembly 6 includes multiple insert rods 601, with a conical rod 602 at the lower part of each insert rod 601. The conical rod 602 is inserted into the top of the vertical tube 101, and the multiple insert rods 601 are connected by a connecting rod 604 and a pressure plate 606.

[0035] Meanwhile, a safety net is installed on the underside of the connecting rod 604 and the pressure plate 606 to prevent tools located on the footboard 2 from falling directly to the ground. The tapered rod 602 facilitates the installation and removal of the insertion rod 601 on the vertical pipe 101. The tapered rod 602 promotes efficient overall operation. The connecting rod 604 is installed along the extension direction of the scaffold (i.e., on the relatively longer side), while the pressure plate 606 is installed on the relatively shorter side. The pressure plate 606 and the insertion rod 601 are hinged, and the pressure plate 606 can be opened and closed as needed, facilitating the entry and exit of construction personnel in the work area above the footboard 2.

[0036] In the preferred embodiment, the upper side of the insertion rod 601 is provided with a plurality of second screws 603 along the circumferential direction, and the two sides of the connecting rod 604 are respectively provided with locking rings 605, the locking rings 605 are sleeved on the insertion rod 601, and the second screws 603 are inserted through the pressure plate 606.

[0037] The two locking rings 605 are respectively limited and supported by the second screw 603, ensuring convenient installation. The pressure plate 606 has a third through hole 607 and an arc-shaped notch 608 through its two sides. The third through hole 607 completes the hinge connection with the second screw 603. The tightness of the pressure plate 606 is achieved by adjusting the position and angle of the nut 7. At the same time, the outer diameter of the arc-shaped notch 608 matches that of the second screw 603, and the second screw 603 and the arc-shaped notch 608 are engaged. Nut 7 is also provided on the second screw 603 that mates with the arc-shaped notch 608. When complete fixation is required, the pressure plate 606 ensures the relative safety of the construction personnel through the connecting rod 604. The whole installation and disassembly is convenient and the safety is high.

[0038] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
