Description

Technical Field

[0001] This invention relates to the field of scaffolding technology, and more specifically, to an angle-adjustable base suitable for erecting scaffolding on inclined surfaces. Background Technology

[0002] Scaffolding is commonly used in construction to help workers complete tasks at a certain height. The stability of scaffolding erection is a crucial indicator of its safety. During scaffolding erection, especially in tunnel and slope scaffolding, sloping foundations are frequently encountered. For example, in water conservancy and highway tunnel construction, the foundation pavement needs to have a certain slope according to the design drawings. After excavation using methods such as blasting, scaffolding needs to be erected on the inclined surface to support or lining the slope, tunnel sidewalls, or arches. However, because the steel pipe columns used in scaffolding erection have flat bottoms, placing them directly on a sloping foundation can lead to uneven stress distribution and stress concentration at the bottom of the scaffolding. This can damage the poured concrete panels or even cause the entire scaffolding to tilt and collapse, affecting construction safety.

[0003] In actual construction, in order to overcome the problem of unstable scaffolding erection on slopes, the common method is to use self-made triangular wooden wedges or steel plates with socket sleeves as temporary scaffolding bases. See Figure N, which shows a diagram of manually made wooden wedges placed at the bottom of scaffolding uprights. Although this method can solve the problem of scaffolding erection on slopes, it also has two disadvantages: (1) As the slope of the foundation road changes, wooden wedges with different slopes need to be continuously processed and made, which is time-consuming and material-intensive; (2) Due to the technical level and subjectivity of the processing workers, the slope of the self-made wooden wedges may not be consistent with the actual road slope, resulting in scaffolding still being erected on a non-horizontal surface, which poses a safety risk. Summary of the Invention

[0004] The purpose of this invention is to provide an angle-adjustable base suitable for scaffolding erection on inclined surfaces. It cleverly combines a toothed eccentric self-weight adjusting wheel, a force transmission plate, a connector, and a pin into a linkage structure. By lifting the second pin and the force transmission plate up and down, the toothed eccentric self-weight adjusting wheel rotates to the corresponding position and engages with the second support plate, realizing the slope leveling function, greatly enhancing structural stability, ensuring the overall safety of the scaffolding during construction, and solving the problems pointed out in the background art.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Example 1

[0026] refer to Figure 1 This embodiment provides an angle-adjustable base suitable for erecting scaffolding on inclined surfaces, including a first support plate 2, a second support plate 8, and side plates 7 disposed on both sides of the second support plate 8, which are spaced apart vertically.

[0027] The first support plate 2 has a connector on its upper part, which is used to connect the scaffold when it is installed; specifically, the connector can be welded to the upper part of the first support plate 2.

[0028] The lower part of the first support plate 2 is provided with a force transmission plate 4. The side plate 7 is provided with a first mounting hole and a second mounting hole. The first end of the force transmission plate 4 is hinged to the side plate 7 through a first pin provided in the first mounting hole. By rotating the first end of the force transmission plate 4 relative to the first pin, the first support plate 2 and the second support plate 8 are driven to rotate relative to each other, so that the first support plate 2 and the second support plate 8 are parallel or form an angle.

[0029] Furthermore, to support the rotation of the first end of the force transmission disk 4, the second mounting hole is an arc-shaped channel 9. The second end of the force transmission disk 4 is movably connected to the side plate 7 via a second pin located within the arc-shaped channel 9. The first pin is parallel to the second pin. During installation, after the relative angles of the first support plate 2 and the second support plate 8 are determined, the second pin is fixed within the arc-shaped channel 9 by the first mounting component. It should be noted that the connected portion of the pins is a smooth surface and therefore does not affect the rotation of the connecting rod components. The first mounting component is pre-installed with the pins, but it does not tightly tighten the connected components, thus not restricting the sliding of the components along the arc-shaped track.

[0030] Specifically, an eccentric self-weight adjusting wheel is sleeved on the second pin shaft; in one embodiment of this example, the eccentric self-weight adjusting wheel is a custom type, which consists of two parts. The first part, which occupies 3 / 4 of the circle, has a bolt hole at its center. The hole is smooth and without threads. The first part is sleeved on the second pin shaft through the bolt hole. The second part, which occupies 1 / 4 of the circle, is a concentric circle with a variable diameter. The arc edge of the second part of the eccentric self-weight adjusting wheel has a toothed groove 10 on the contact surface between it and the second support plate 8.

[0031] The principle of the angle-adjustable base provided by the present invention is explained below: The angle-adjustable base is cleverly combined into a linkage structure by a toothed eccentric self-weight adjusting wheel 5, a force transmission plate 4, a connecting piece, and a pin. The linkage structure, together with the first support plate 2, the second support plate 8, and the side plate 7, forms a single-sided variable triangular stable structure. The variable single side is provided by the toothed eccentric self-weight adjusting wheel 5 with a 1 / 4 diameter variable diameter. By rotating the toothed eccentric self-weight adjusting wheel 5, the single side of the triangular stable structure is changed, thereby adjusting the angle between the first support plate 2 and the second support plate 8. One side of the triangular stable structure is placed on an inclined plane, and the other side supports the scaffolding.

[0032] When the second pin rotates along the arc-shaped channel 9, it drives the first end of the force transmission plate 4 to rotate around the first pin. At the same time, the first support plate 2 and the connecting parts supporting the scaffold also rotate. When the first support plate 2 reaches the horizontal, the toothed eccentric self-weight adjusting wheel 5 can be engaged with the toothed groove 10 of the second support plate 8. After leveling is completed, the scaffold can be installed.

[0033] The following further explains the movement of the adjustable base:

[0034] The adjustable base can be used in three steps: safety check, placement of the second support plate 8, leveling of the first support plate 2, and installation of scaffolding.

[0035] Safety check: Check whether the mounting parts are tightened, check whether the second pin can move flexibly along the arc-shaped channel 9, etc., and check the safety status of the angle-adjustable base.

[0036] When setting up scaffolding on an inclined plane, place the side of the base without the toothed eccentric self-weight adjusting wheel 5 on the higher side of the inclined plane, and place the side with the toothed eccentric self-weight adjusting wheel 5 on the lower side of the inclined plane.

[0037] Base leveling: Hold the second pin or connector with one hand and support the toothed eccentric self-weight adjusting wheel 5 with the other hand. Coordinate the two hands so that when the second pin is pushed to move along the arc-shaped channel 9, the toothed eccentric self-weight adjusting wheel 5 rotates in tandem. When the first support plate 2 reaches the horizontal position, the second pin stops moving. At this time, engage the tooth groove 10 of the toothed eccentric self-weight adjusting wheel 5 with the tooth groove 10 of the second support plate 8. The base leveling is then complete.

[0038] After the base is leveled, proceed to the next step of scaffolding installation. The scaffolding uprights and steel pipes can be directly connected to the connectors.

[0039] In summary, the technical solution of the angle-adjustable base for scaffolding erection on inclined surfaces according to the embodiments of the present invention has at least the following advantages and beneficial effects: The angle-adjustable base is cleverly combined into a linkage structure (suitable for inclination angles of 0° to 20°) by toothed eccentric self-weight adjusting wheel 5, force transmission plate 4, connecting parts, and pin shaft. By lifting the second pin shaft and force transmission plate 4 up and down, the toothed eccentric self-weight adjusting wheel 5 is rotated to the corresponding position, and then the toothed eccentric self-weight adjusting wheel 5 is engaged with the second support plate 8, realizing the slope leveling function, greatly enhancing the structural stability, and ensuring the overall safety of the scaffolding during construction.

[0040] Example 2

[0041] This embodiment is a further improvement on embodiment 1, and the specific improvements are as follows:

[0042] See Figures 2 to 5As shown, the force transmission disk 4 has a certain thickness, and the top surface of the force transmission disk 4 is rigidly connected to the first support plate 2. The force transmission disk 4 includes a first force transmission disk 4 and a second force transmission disk 4. The eccentric self-weight adjusting wheel is arranged between the first force transmission disk 4 and the second force transmission disk 4, and is not rigidly connected, and can rotate along the second pin shaft.

[0043] The lower part of the first support plate 2 is also provided with a reinforcing rib 3. The top surface of the reinforcing rib 3 is rigidly connected to the first support surface, and the side surface of the reinforcing rib 3 is rigidly connected to the force transmission plate 4. In one embodiment of this example, the reinforcing rib 3 is arranged between the first pin and the second pin, and is composed of the first reinforcing rib 3 and the second reinforcing rib 3. The second reinforcing rib 3 near the second pin forms a rotation avoidance area for the eccentric self-weight adjustment wheel between it and the second pin, so as to reserve the space required for the rotation of the eccentric self-weight adjustment wheel when the base is adjusted.

[0044] Furthermore, the connector is a socket sleeve 1, which has a certain wall thickness and is vertically connected to the center of the first support plate 2; the diameter of the socket sleeve 1 matches the scaffolding, and its length is determined according to the stress calculation of the scaffolding used.

[0045] Furthermore, the first pin is fixed in the first mounting hole by the second mounting component. Both the first and second pins are high-strength double-ended bolts 6, and both the first and second mounting components are nuts that mate with the high-strength double-ended bolts 6.

[0048] The eccentric self-weight adjusting wheel includes a first eccentric self-weight adjusting wheel and a second eccentric self-weight adjusting wheel, which are respectively arranged on both sides of the force transmission plate 4.

[0049] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
