Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to an angle-adjusting base for a slope surface scaffolding. Background Art

[0002] With the development of urban construction in China, projects such as underground garage ramps and dam buildings are common. During the erection of scaffolding, slopes are often inevitably encountered on-site. Due to the slope, conventional scaffolding bases cannot fit completely with the foundation surface, resulting in uneven stress on the scaffolding base and even overturning, thus posing a greater safety hazard. Currently, most of the scaffolding used in projects is the disk-locked scaffolding, with a fixed spacing between the vertical poles and a relatively high requirement for the accurate positioning of the vertical poles. Traditional methods for erecting scaffolding on a slope surface include adding wedge-shaped wooden blocks and chiseling and leveling the slope surface. These methods not only have safety hazards but also consume a lot of manpower and financial resources and have poor usage effects. Therefore, there is an urgent need to design a scaffolding base that can flexibly adjust the angle on a slope surface to meet the construction requirements of erecting scaffolding on an uneven slope surface. Content of the Utility Model

Detailed Embodiments

[0018] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the present invention in combination with the accompanying drawings and the description of the embodiments or the prior art. Obviously, the following description of the structures of the drawings is only some embodiments of the present invention. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention.

[0019] Embodiment:

[0020] As Figures 1-5 shown, this embodiment provides an angle-adjusting base for a scaffold on a slope, including a scaffold 7. The scaffold 7 includes a plurality of vertically arranged vertical rods 6. The bottom of the vertical rod 6 is threadedly connected with an adjusting screw rod 4. The bottom of the adjusting screw rod 4 is fixedly connected with a connecting member 3. At the middle parts on both the left and right sides of the connecting member 3, connecting gear discs 31 are fixedly connected. On one side of the connecting gear disc 31, a support gear disc 211 is engaged. The support gear disc 211 is fixedly connected to the top of one side of the engaging support 2. The bottom of the engaging support 2 is slidably connected to the top of the steel base plate 1 and is fixed in position with the steel base plate 1 through a positioning bolt 11. The two engaging supports 2, the two support gear discs 211, the connecting member 3 and the two connecting gear discs 31 are connected in series through a reinforcing bolt 21. The end of the reinforcing bolt 21 is threadedly connected with a reinforcing nut 23. The two engaging supports 2, the two support gear discs 211, the connecting member 3 and the two connecting gear discs 31 are tightly connected through the reinforcing bolt 21 and the reinforcing nut 23.

[0021] Specifically, as shown in the figure, there are two engaging supports 2, and support gear discs 211 are provided on the upper parts, which are respectively engaged and connected to both sides of the connecting member 3. Preferably, threaded holes are reserved at the lower parts of the engaging supports 2. The support gear discs 211 are distributed in a circular ring shape, and a threaded hole for the reinforcing bolt 21 is reserved in the middle of the circular ring; furthermore, the connecting member 3 and the adjusting screw rod 4 are integrally formed. Connecting member discs are provided on both sides of the connecting member 3, and a horizontal bubble 32 is provided at the top to ensure that after installation, the connecting member 3 is perpendicular to the horizontal plane. The connecting member discs are distributed in a circular ring shape, and a threaded hole for the reinforcing bolt 21 is reserved in the middle of the circular ring; the engaging support 2 and the connecting member 3 are also fixed and locked with a reinforcing bolt 21, a reinforcing gasket 22 and a reinforcing nut 23; through holes are provided on both sides of the steel base plate 1, and a dovetail groove 12 is provided at the top. The positioning bolt 11 passes through the through hole and enters the dovetail groove 12 and is then threadedly connected to a dovetail slider 24 integrally formed at the bottom of the engaging support 2. By rotating the positioning bolt 11, the dovetail slider 24 can be driven to slide in the dovetail groove 12, so as to drive the connecting gear disc 31 to separate from or engage with the support gear disc 211.

[0022] During actual construction and use, first, adjust the two interlocking brackets 2 and the connecting piece 3 to an angle suitable for the slope. At this time, attention should be paid to whether the horizontal bubble 32 on the top of the connecting piece 3 is horizontally centered, and then the bracket toothed disc 211 is interlocked and locked with the toothed disc of the connecting piece 3, and the interlocking bracket 2 and the connecting piece 3 are fastened together with the reinforcing bolts 21. Finally, the interlocking bracket 2 is inserted into the dovetail groove 12 in the steel base plate 1, and is tightened and fixed with the positioning bolts 11 on that side to ensure the stability of the toothed disc interlocking base and the upper scaffolding 7 structure. There are several toothed disc interlocking bases, and the multiple toothed disc interlocking bases are independently regulated. Compared with the integrated base structure, several toothed disc interlocking bases can form a stronger supporting effect. Although they need to be regulated separately during regulation, their structure is simple and reasonable, and more in line with the structure of the scaffolding 7 on the slope surface.

[0023] The base of the traditional scaffolding 7 is a right-angled consolidation type. Therefore, if it is used to set up the scaffolding 7 on a slope, it is necessary to add a wooden wedge to its bottom or chisel the local contact surface of the base flat. The toothed disc interlocking base of this embodiment can adjust the angle between the interlocking bracket 2 and the connecting member 3 to achieve seamless fitting between the base of the scaffolding 7 and the slope surface. The interlocking bracket 2 and the connecting member 3 are fixed by toothed disc interlocking and reinforcing bolts 21, which can ensure the uniformity of the load on the upper scaffolding 7. In addition, this study will also combine finite element software to simulate and analyze the local node forces of the toothed disc interlocking base and the overall force stability of the scaffolding 7 to ensure the safety of the invention. Finally, the actual safety of the invention is tested by the method of scaled-down model test to ensure that the safety performance fully meets the requirements before it is applied in engineering practice.

[0024] It should be noted that the maximum slope allowed in the design of roads, underground garages and other buildings in engineering construction can be found by consulting the specifications, so as to determine the adjustment angle allowed by the present invention. Specifically, the adjustment angle is based on the maximum road slope of no more than 15% specified in the "Urban Road Engineering Design Specifications" CJJ 37-2012.

[0025] Therefore, when designing the toothed disc engaging base, the inclination angle between the engaging bracket 2 and the bottom connecting piece 3 of the adjusting screw rod 4 can meet 15%, and the maximum static friction force is verified according to the friction coefficient between the steel base plate 1 material and the slope surface to ensure that no sliding will occur when the toothed disc engaging support is applied on the slope surface. Therefore, the adjustment angle is determined through specifications to ensure that the scaffolding 7 does not slide sideways, thereby ensuring construction safety.

[0026] In a preferred embodiment of the present utility model, further, dovetail grooves 12 are respectively formed on the left and right sides of the top of the steel base plate 1 and are respectively close to the connecting member 3. A dovetail slider 24 is fixedly connected to the bottom of the clamping bracket 2. The dovetail slider 24 is slidably connected in the dovetail groove 12. The left or right side of the positioning bolt 11 is inserted into the dovetail groove 12 and is threadedly connected to the dovetail slider 24.

[0027] In a preferred embodiment of the present utility model, further, a reinforcing gasket 22 is sleeved on the outer portion of the positioning bolt 11. The reinforcing gasket 22 is located between the connecting member 3 and the head of the positioning bolt 11.

[0028] In a preferred embodiment of the present utility model, further, a rotating nut 5 is rotatably connected to the bottom of the vertical rod 6. The top of the adjusting screw rod 4 is threadedly connected to the rotating nut 5.

[0029] In a preferred embodiment of the present utility model, further, a level bubble 32 is arranged on the top of the connecting member 3.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
