Description

Technical Field

[0001] This utility model relates to the field of scaffolding erection technology, specifically an adjustable support for erecting scaffolding on a large inclined plane. Background Technology

[0002] In the construction industry, scaffolding is an indispensable tool, especially in the construction of tunnels, slopes, and other special terrains, where its role is particularly important. In traditional construction operations, when facing sloping foundation surfaces, such as ramps with significant elevation differences, construction workers usually adopt two methods to ensure the stability of the scaffolding: one is to pre-embed steel bars before pouring concrete to provide support points for subsequent scaffolding; the other is to re-drill holes and weld steel bar supports at the required locations after the concrete has cured to adapt to specific slope conditions.

[0003] However, both methods have significant limitations and potential safety hazards. First, the method of pre-embedded reinforcing bars relies on pre-cast estimations for scaffold upright positioning, often leading to upright position deviations during later scaffolding erection. Second, while drilling and welding reinforcing bars after concrete curing allows for customized treatment of specific slopes, this method is time-consuming and labor-intensive, and the resulting reinforcing bar supports can only be used once, increasing construction costs. More importantly, regardless of the method, the lack of an effective angle adjustment mechanism makes it difficult to ensure the final scaffolding is completely perpendicular to the ground, affecting not only its stability but also posing a threat to construction safety.

[0004] Therefore, it is necessary to invent an adjustable support for the erection of scaffolding on steep slopes to solve the above problems. Utility Model Content

[0005] To address the problems of positioning deviation, low construction efficiency, high cost, and insufficient safety in existing scaffolding erection methods on inclined foundations, this utility model provides an adjustable support for the erection of scaffolding on steep inclines.

[0006] This utility model is achieved using the following technical solution:

[0007] An adjustable support for erecting scaffolding on a steep slope includes an upper support structure and a lower support structure.

[0008] The upper support structure includes an upper support vertical rod, and two horizontal support rods are fixedly intersecting at the lower part of the upper support vertical rod;

[0009] The lower support structure includes a lower support vertical rod, and two horizontal auxiliary rods are fixedly intersecting at the middle of the lower support vertical rod;

[0010] A connecting plate is fixed to the bottom end of the upper support vertical rod and the top end of the lower support vertical rod. The opposing surfaces of the two connecting plates are serrated and interlocked. Bolt holes are opened in the middle of the two connecting plates. The bottom end of the upper support vertical rod and the top end of the lower support vertical rod are fixedly connected by nuts and bolts passing through the bolt holes.

[0011] Furthermore, a wooden pad is fitted onto the upper support vertical rod, and the lower surface of the wooden pad is attached to the upper surface of the two horizontal support rods.

[0012] Furthermore, the upper support vertical rod, horizontal support rod, lower support vertical rod, and horizontal auxiliary rod are all made of HRB400 steel bars with a diameter of 25mm.

[0013] Furthermore, the wooden pad has a length and width of 100mm and a thickness of 20mm.

[0014] Furthermore, the connecting plate is made of steel plate, and the bottom end of the upper support vertical rod and the corresponding connecting plate are fixed by welding, as are the top end of the lower support vertical rod and the corresponding connecting plate.

[0015] This utility model features a reasonable and reliable structural design, improving the speed and accuracy of scaffolding erection. Its adjustability avoids deviations caused by inaccurate estimations on inclined foundations, a problem common in existing scaffolding methods. It is applicable to slopes with an inclination range of 0 to 90 degrees, demonstrating strong applicability. It saves materials and costs, eliminating the need for additional, disposable steel reinforcement supports. Safety is enhanced by precise angle adjustments, ensuring the scaffolding remains perpendicular to the ground and improving the overall structural stability. Furthermore, the upper support structure is reusable, reducing long-term construction costs. Attached Figure Description

[0022] The present invention will now be clearly and completely described with reference to the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0023] An adjustable support for erecting scaffolding on a steep slope, as shown in the attached figure. Figure 2 ~Appendix Figure 5 As shown, it includes an upper support structure and a lower support structure;

[0024] The upper support structure includes an upper support vertical rod 1, and two horizontal support rods 2 are fixedly intersecting at the lower part of the upper support vertical rod 1.

[0025] The lower support structure includes a lower support vertical rod 3, and two horizontal auxiliary rods 4 are fixedly intersecting at the middle of the lower support vertical rod 3;

[0026] The bottom end of the upper support vertical rod 1 and the top end of the lower support vertical rod 3 are both fixed with a connecting plate 5. The opposite surfaces of the two connecting plates 5 are serrated and interlocked with each other. Bolt holes 6 are opened in the middle of the two connecting plates 5. The bottom end of the upper support vertical rod 1 and the top end of the lower support vertical rod 3 are fixedly connected by nuts 8 and bolts 7 that pass through the bolt holes 6.

[0027] In this embodiment, as shown in the appendix Figure 1 As shown, a ramp 11 is set on the ground, and scaffold uprights 10 are installed on the ramp 11 via adjustable supports.

[0028] A wooden pad 9 is fitted onto the upper support rod 1, and the lower surface of the wooden pad 9 is attached to the upper surface of the two horizontal support rods 2.

[0029] During installation and use, firstly, when pouring concrete on slope 11, the lower support vertical rod 3 of the lower support structure is pre-embedded in the concrete, and the lower surfaces of the two horizontal auxiliary rods 4 are made to fit against the slope of slope 11. After the concrete strength of slope 11 reaches the required level, according to the actual slope of slope 11, the bolts 7 are loosened, and the upper support structure is rotated until the upper support vertical rod 1 is perpendicular to the ground. Then, the bolts 7 and nuts 8 are tightened to ensure that the two connecting plates 5 of the upper support vertical rod 1 and the lower support vertical rod 3 are serrated. The surfaces are fully engaged. Then, the wooden pad 9 is fitted onto the upper support rod 1, so that its lower surface is in contact with the upper surface of the two horizontal support rods 2. Finally, the scaffold upright 10 is inserted into the upper support rod 1, ensuring that the bottom end of the scaffold upright 10 abuts against the upper surface of the wooden pad 9. Through the upper erection of the scaffold, the upper load-bearing capacity of the scaffold is transferred to the wooden pad 9 through the scaffold upright 10, thereby making the scaffold upright 10 stably placed on the upper surface of the wooden pad 9. This completes the installation and use of this adjustable support.

[0030] In this invention, two horizontal support rods 2 are cross-welded and fixed to the lower part of the upper support vertical rod 1, and two horizontal auxiliary rods 4 are cross-welded and fixed to the middle part of the lower support vertical rod 3, forming a stable foundation frame. The upper support structure and the lower support structure are connected by two interlocking connecting plates 5, both with serrated surfaces, and fixed by nuts 8 and bolts 7. This design allows for adjustment of the angle between the upper and lower support structures within a certain range, thereby adapting to slopes 11 with different inclines. This solves the problem of the lack of angle adjustment mechanism on inclined foundation surfaces in existing scaffolding construction methods, ensuring that the scaffolding can be erected perpendicular to the ground. The upper and lower support structures work together to provide sufficient strength and stability to support the weight of the scaffolding uprights 10 and effectively transfer their load to the slope 11, enhancing the stability and safety of scaffolding installation on the slope 11. This overcomes the problems of positioning deviation, low construction efficiency, high cost, and insufficient safety in existing scaffolding construction methods on inclined foundation surfaces.

[0031] The design of the wooden pad 9 can increase the contact area between the bottom of the scaffold upright 10 and the horizontal support rod 2, reduce the pressure on the upper surface of the horizontal support rod 2, prevent the deformation of the horizontal support rod 2, and increase the friction, thereby improving the stability and safety of the scaffold erection.

[0032] The upper support rod 1, horizontal support rod 2, lower support rod 3, and horizontal auxiliary rod 4 are all made of HRB400 steel bars with a diameter of 25mm.

[0033] HRB400 steel bars have high strength and good tensile properties, ensuring the durability and reliability of the entire adjustable support structure.

[0034] The wooden pad 9 has a length and width of 100mm and a thickness of 20mm.

[0035] The connecting plate 5 is made of steel plate, and the bottom end of the upper support vertical rod 1 and the corresponding connecting plate 5 are fixed by welding, as are the top end of the lower support vertical rod 3 and the corresponding connecting plate 5.
