Description

Technical Field

[0001] This utility model relates to, but is not limited to, the field of scaffolding technology, and more specifically, to a scaffolding installation base structure. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It is used in areas where construction is difficult due to high ceilings, such as exterior walls, interior decoration, or other high-ceilinged areas. It is mainly used for workers to move up and down, for external safety netting, and for installing components at height. Scaffolding is classified by its location as external scaffolding or internal scaffolding, and by its structural form as pole-mounted, bridge-type, and portal-type scaffolding, among others.

[0003] Among them, steel pipe upright scaffolding is the most widely used. Its base usually adopts a welded base plate or a four-bolt flange structure. The former requires on-site hot welding and cutting during dismantling, which is time-consuming and damages the galvanized layer of the upright. The latter requires four bolts to be inserted one by one, and the tightening torque is not easy to control. When encountering uneven ground, wooden pads or cement pads need to be added, making the process complicated.

[0004] Both traditional scaffolding bases rely on rigid multi-point connections to resist lateral displacement, lacking elastic clamping capabilities. This makes them prone to loosening or weld cracking, leading to base slippage and jeopardizing the overall stability of the scaffolding. Therefore, a more stable scaffolding installation base structure is designed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a scaffolding installation base structure.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] This utility model discloses a scaffolding installation base structure, including a scaffolding support base frame. The scaffolding support base frame includes four uprights, a horizontal frame located between the uprights, and diagonal braces placed on the outside of the uprights. A scaffolding installation frame is provided on the top of the scaffolding support base frame. The scaffolding installation frame includes a support plate disposed on the uprights and a scaffolding upright fixing member located on the surface of the support plate. The scaffolding fixing member includes a base plate, a fixing seat located on the upper surface of the base plate, a screw rod passing through the fixing seat, and an abutment plate disposed on the inner end of the screw rod.

[0008] Preferably, a plurality of scaffolding upright fixing components are equidistantly arranged on the upper surface of the support plate, the screw is threadedly engaged with the fixing seat and screwed to the abutment plate.

[0009] Preferably, a fixing plate is installed at the end away from the fixing seat, the fixing plate is arranged opposite to the abutment plate, the abutment plate is L-shaped, and the abutment plate is movably connected to the base plate.

[0010] Preferably, the surface of the support plate has a pole connection hole through which the pole passes, and the pole is bolted to the support plate.

[0011] Preferably, a reinforcing frame is provided on the inner side of the scaffold upright fixing component. The reinforcing frame has a U-shaped cross-section. The top of the reinforcing frame and the surface of the base plate are provided with scaffold upright mounting holes for the scaffold upright to pass through.

[0012] Preferably, the base plate is either V-shaped or square.

[0013] Preferably, the base plate is "V" shaped, and the fixing seat is fixed at both ends of the upper surface of the base plate.

[0014] Preferably, the base plate is square, and a fixing seat is fixed to one end of the upper surface of the base plate.

[0015] Preferably, each of the four corners of the horizontal frame is provided with a connecting end through which the upright is passed, and at least two horizontal frames are provided on the upright. The bottom of the lower horizontal frame is screwed to a movable base frame, which includes a steel beam connected to the horizontal frame and movable wheels installed at both ends of the steel beam.

[0016] Preferably, a connecting block is provided between the diagonal brace and the upright, one end of the connecting block is sleeved on the outside of the upright and screwed to the diagonal brace, and a pad is fixed at the bottom end of the diagonal brace.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This utility model replaces traditional welding or four-bolt flanges with clamping. The uprights are directly clamped after insertion, making assembly and disassembly quick and significantly improving construction efficiency. A reinforcing frame can be selectively added to increase the contact area and friction with the scaffold uprights, forming an auxiliary constraint. Under the same pipe diameter conditions, this enhances the base's resistance to lateral displacement and improves the overall stability and safety of the scaffold.

[0033] like Figure 1-10 As shown, this utility model provides a scaffolding installation base structure, including a scaffolding support base 1. The scaffolding support base 1 includes four uprights 11, a horizontal frame 12 located between the uprights 11, and diagonal bracing rods 13 placed outside the uprights 11. A scaffolding installation frame 2 is provided on the top of the scaffolding support base 1. The scaffolding installation frame 2 includes a support plate 21 set on the uprights 11 and a scaffolding upright fixing member located on the surface of the support plate 21. The scaffolding 4 fixing member includes a base plate 22, a fixing seat 23 located on the upper surface of the base plate 22, a screw 24 passing through the fixing seat 23, and an abutment plate 25 set at the inner end of the screw 24.

[0034] Furthermore, in this embodiment, a number of scaffolding upright fixing parts are equidistantly arranged on the upper surface of the support plate 21. The number of scaffolding 4 fixing parts is determined according to the number of scaffolding uprights. The screw 24 is threadedly engaged with the fixing seat 23 and screwed to the abutment plate 25. By rotating the screw 24, the screw 24 rotates and adjusts on the fixing seat 23, and controls the movement of the abutment plate 25 at its end.

[0035] In this embodiment, a fixing plate 26 is installed at the end away from the fixing seat 23. The fixing plate 26 and the abutment plate 25 are arranged opposite to each other. The fixing plate 26 and the abutment plate 25 cooperate to form a clamping structure for directly clamping the scaffold uprights. The abutment plate 25 has an L-shaped design and is movably connected to the base plate 22. By rotating the screw 24, the abutment plate 25 can be driven to move closer to or away from the fixing plate 26, thereby adjusting the clamping force and directly fastening the scaffold uprights placed therebetween.

[0036] In this embodiment, the surface of the support plate 21 is provided with a pole connection hole 27 for the pole 11 to pass through. The pole 11 is bolted to the support plate 21. The support plate 21 is installed on the scaffold support base 1 through the pole connection hole 27 and fixed with bolts.

[0037] To further enhance the stability and anti-lateral displacement capability of the clamping mechanism, as a preferred embodiment, the reinforcing frame 3 serves to distribute the pressure of the clamping points on the scaffold uprights, preventing localized indentation of the scaffold uprights. Its U-shaped structure allows for a larger contact area with the outer wall of the scaffold uprights, enhancing the anti-slip effect by increasing static friction. The reinforcing frame 3 is provided on the inner side of the scaffold upright fixing component. The shape of the reinforcing frame 3 is determined by the installation position of the scaffold upright fixing component. For example, if the scaffold upright fixing component is installed at the four corners of the support plate 21, then the reinforcing frame 3 is a square design. The cross-section of the reinforcing frame 3 is U-shaped, which allows the two side walls of the reinforcing frame 3 to contract inward when it is clamped by the abutment plate 25 and the fixing plate 26. This causes the scaffolding uprights installed through the scaffolding upright mounting holes 28 inside the reinforcing frame 3 to be squeezed by the reinforcing frame 3, thus improving the stability of the scaffolding upright installation. Compared with single-point clamping, this two-point clamping structure can provide better torsional stability and clamping reliability. The top and bottom plates 22 of the reinforcing frame 3 are provided with scaffolding upright mounting holes 28 for the scaffolding uprights to pass through.

[0038] It should be noted that the reinforcing frame 3 is made of a thin metal plate with a certain degree of elasticity (such as Q235B cold-formed steel with a wall thickness of 1.5mm-2.0mm). Its cross-section is U-shaped. When the reinforcing frame 3 is clamped by the abutment plate 25 and the fixing plate 26, its U-shaped sidewall will undergo slight elastic deformation, thus fitting more tightly to the outer wall of the scaffold upright. This increases the contact area and friction to improve the clamping effect. The single-sided gap (0.4mm-0.6mm) between the inner hole of the reinforcing frame 3 and the outer diameter of the scaffold upright ensures the smooth insertion of the upright before clamping and provides space for elastic deformation.

[0039] Considering the stability of scaffolding 4, screws or bolts can be used for final fixing after the scaffolding uprights are installed to improve stability.

[0040] In this embodiment, the base plate 22 is "V" shaped, and the upper surface of the base plate 22 is fixed with a fixing seat 23 at both ends, so that the abutment plate 25 applies clamping force to both sides of one corner of the reinforcing frame 3 at the same time, thereby increasing the clamping force generated when the reinforcing frame 3 is squeezed.

[0041] In this embodiment, each of the four corners of the horizontal frame 12 is provided with a connecting end 14 through which the upright 11 passes. At least two horizontal frames 12 are provided on the upright 11, and the upright 11 is connected together by the horizontal frames 12 and fixed with bolts. An inclined steel beam is provided between the two horizontal frames 12 for stability. The bottom of the lower horizontal frame 12 is screwed to a movable base frame 17. The movable base frame 17 includes a steel beam connected to the horizontal frame 12 and movable wheels installed at both ends of the steel beam. The detachable movable base frame 17 is selected for installation according to whether the scaffolding 4 needs to be rotated as a whole. In construction scenarios that require rotation, the movable base frame 17 is pre-installed and moved by the movable wheels, which are equipped with foot brakes.

[0042] In this embodiment, a connecting block 16 is provided between the diagonal brace 13 and the upright 11. One end of the connecting block 16 is sleeved on the outside of the upright 11 and screwed to the diagonal brace 13. The diagonal brace 13 is installed through the connecting block 16 to support the upright 11 and improve stability. Both the upright 11 and the diagonal brace 13 are in contact with the ground. The angle of the diagonal brace 13 needs to ensure that it can effectively support the upright 11. The bottom ends of the diagonal brace 13 and the upright 11 are fixed with pads 15. The pads 15 assist the contact between the diagonal brace 13 and the upright 11 and the ground to improve stability. The pads 15 can be made of rubber.

[0043] Specifically, the usage process of the scaffolding 4 mounting base:

[0044] Check all parts for deformation, cracks, thread damage, etc. Remove obstacles and ensure that the bottom of the upright 11 and the diagonal brace 13 can make stable contact with the ground. If the ground is soft, a pad or hardening treatment is required. Mark the position of the upright 11 according to the construction drawings and ensure that the scaffold upright fixing parts are aligned with the subsequent upright 11.

[0045] Place four uprights 11 vertically in the predetermined positions. Fit at least two horizontal frames 12 (distributed vertically) onto the uprights 11, aligning the connecting ends 14 at the four corners of the horizontal frames 12 with the uprights 11. Secure the horizontal frames 12 to the uprights 11 with bolts, ensuring that the horizontal frames 12 are horizontal. Install connecting blocks 16 on the outside of the uprights 11, with one end of the connecting block 16 fitted onto the uprights 11 and the other end bolted to the diagonal brace 13. Adjust the angle of the diagonal brace 13 so that its bottom end contacts the ground, forming a stable triangular support. Install rubber pads 15 at the bottom of the uprights 11 and the diagonal brace 13 to increase friction and prevent slippage.

[0046] If the scaffolding 4 needs to be moved, bolt the movable base frame 17 (steel beam + movable wheels) to the bottom of the lower horizontal frame 12, and ensure that the movable wheels are equipped with foot brakes. After installation, lock the foot brakes to prevent slippage.

[0047] Place the support plate 21 on top of the upright 11, so that the top of the upright 11 passes through the upright connection hole 27 on the support plate 21. Use bolts to fasten the support plate 21 to the upright 11 to ensure that it is level and does not wobble. According to the required number of scaffold uprights, install the corresponding number of scaffold upright fixing parts at equal intervals on the support plate 21. Place the base plate 22 on the support plate 21 with the fixing seats 23 at both ends facing upwards. Place the reinforcing frame 3 in the center of the base plate 22 so that the scaffold upright mounting holes 28 of the two are aligned. Insert the scaffold upright into the mounting holes of the reinforcing frame 3 and the base plate 22, but do not penetrate the support plate 21.

[0048] Manually rotate screw 24 to move abutment plate 25 to the side of reinforcing frame 3. Since base plate 22 is V-shaped, abutment plate 25 simultaneously applies pressure to adjacent sides of reinforcing frame 3. Continuously tighten screw 24 to cause the side walls of reinforcing frame 3 to contract inward, squeezing and holding the scaffold uprights. At the same time, fixing plate 26 and abutment plate 25 form a clamping structure, providing support from the opposite side to prevent uprights 11 from swaying. Finally, use bolts or screws to fix the scaffold uprights to reinforcing frame 3 and base plate 22 a second time (such as adding a clamp or through bolts at the top). Each upright 11 uses at least two fasteners (distributed vertically, i.e., the upper and lower surfaces of support plate 21) to improve resistance to lateral displacement.

[0049] After installation, check the tightness of all bolts, ensure that all diagonal braces 13 are evenly stressed, and that the pads 15 are in full contact with the ground without any gaps. Continue to erect horizontal bars, footboards, guardrails, safety nets, etc. on the scaffolding uprights, and install wall ties to connect with the building structure according to specifications to prevent overturning.

[0050] During dismantling, first remove the horizontal bars and scaffold boards on the scaffold uprights, loosen the bolts 24, remove the abutment plate 25, take out the reinforcing frame 3 and the upright 11, remove the connecting bolts between the support plate 21 and the upright 11, remove the support plate 21, remove the connecting block 16 of the diagonal brace 13, remove the diagonal brace 13, remove the connecting bolts between the horizontal frame 12 and the upright 11, remove the horizontal frame 12, and if a movable base frame 17 is installed, finally remove the movable base frame 17, sort and stack all components, check for wear and tear, and perform maintenance.

[0051] like Figure 6 and 10 As shown, based on the above-mentioned direct clamping structure, this utility model also provides a simplified structure. In this solution, the base plate 22 is square, and a fixing seat 23 is fixed at one end of the upper surface of the base plate 22. The scaffolding upright passes through the base plate 22 and the support plate 21 through the scaffolding upright mounting hole 28 and extends to the ground, abutting against the ground. The scaffolding upright is directly clamped by the cooperation of the abutment plate 25 and the fixing plate 26. This solution has a simpler structure and lower cost.

[0052] Specifically, after the scaffold upright is inserted, the screw 24 controls the abutment plate 25 and the fixing plate 26 to form a horizontal clamp, which directly clamps the outer wall of the upright 11. The clamping force is controlled by torque. Since the upright 11 has been placed on the ground, the axial load is no longer transmitted through the reinforcing frame 3. Therefore, in this embodiment, the reinforcing frame 3 is eliminated, reducing one vulnerable part and further reducing weight and cost.

[0053] To further improve the clamping effect, a flexible bushing (such as a rubber bushing) can be installed between the scaffold upright and the clamping mechanism (abutment plate 25 and fixing plate 26), or between the scaffold upright and the scaffold upright mounting hole 28. This bushing can compensate for the gap, increase friction and absorb vibration.

[0054] The uprights 11, horizontal frames 12, diagonal braces 13, screws 24, scaffolding 4, and other components of this utility model are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0055] In the description of this utility model, it should be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "side", "top", "inner", "front", "center", "both ends", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0056] Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first," "second," "third," or "fourth" may explicitly or implicitly include at least one of those features.

[0057] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly.
