Description

Technical Field

[0001] The utility model belongs to the technical field of building construction and installation, and in particular relates to a scaffolding support device suitable for rock slope terrain. Background Art

[0002] With the development of social economy and the needs of actual social life, more and more projects are being sited and constructed in mountainous areas. Mountainous areas are usually characterized by undulating terrain and steep slopes, which poses challenges to engineering construction. In addition, in order to protect the ecology and save construction costs, construction workers generally only deal with rugged terrain in a simple manner and try to keep the original terrain of the surface as much as possible, which poses challenges to engineering construction. In engineering, in most cases, scaffolding is required to build longitudinal mobile passages and working platforms for construction workers. It is also used to build peripheral safety nets. Scaffolding also plays an important role in the construction and support of concrete formwork. However, the current scaffolding supports are usually designed for flat conditions, and the supports are generally simply supported and placed on the ground, lacking the ability to stabilize the overall scaffolding system on mountain rock slopes. The commonly used solution in engineering is to cast steps on the ground so that the scaffolding has similar erection conditions as the flat environment, but this method takes a lot of construction time and the scaffolding structure lacks stability.

[0003] Therefore, it is necessary to provide a scaffolding support device suitable for rock slope terrain to solve the above technical problems. Utility Model Content

[0019] Furthermore, the base plate 1 includes a central base plate 101, and three corner base plates 102 on the periphery are connected to the central base plate 101 through a rotating shaft, and the rock fixing system 4 can pass through the base plate 1 through the through holes opened on the corner base plates 102; during installation, the device is firstly adjusted to adapt to the rugged terrain according to the rock slope terrain by adjusting the rotating shaft angle, which can effectively increase the contact area with the rugged terrain of the slope, thereby increasing the friction between the device and the slope when the device is subjected to the upper gravity.

[0020] like Figure 2 As shown, the scaffold fixing system 2 includes a spherical shaft base 201, a spherical shaft 202, a fixing sleeve 203, a fixing clamp 204 and a tightening knob 205.

The fixing sleeve 203 is fixed above the spherical shaft 202. The tightening knob 205 is connected to the fixing sleeve 203 through a thread. The interior below the tightening knob 205 is provided with a slope angle, which contacts the external slope angle above the fixing clamp 204 during the process of rotation and descent. The further rotation and descent of the tightening knob 205 causes the outer wall of the fixing clamp 204 to shrink, thereby clamping and fixing the scaffold bottom pipe 5.

[0021] like Figure 1 As shown, the scaffolding support system 3 includes a first ear plate 301, an upper support rod 302, a support rod tightening knob 303, a lower support rod 304 and a second ear plate 305. The first ear plate 301 is fixed to the side wall of the fixing sleeve 203, and the second ear plate 305 is fixed to the corner base plate 102. The upper support rod 302 is connected to the first ear plate 301 through a rotating shaft, and the lower support rod 304 is connected to the second ear plate 305 through a rotating shaft. The upper support rod 302 and the lower support rod 304 can adjust the support length through a slide groove, thereby controlling the inclination angle of the scaffolding fixing system 2. The upper support rod 302 and the lower support rod 304 are fixed through the support rod tightening knob 303 to complete the support of the bottom of the scaffolding.

[0022] like Figure 3 As shown, the rock fixing system 4 comprises a rock fixing rod 401, a rock fixing expansion tube 402 and a rock fixing nut 403. The lower part of the rock fixing rod 401 is a drill bit, and the drill can be clamped with the upper part of the rock fixing rod 401 to realize drilling in the rock. The middle part of the rock fixing rod 401 is provided with a thread, and the rock fixing nut 403 is connected to the rock fixing rod 401 through a thread. The lower surface of the rock fixing nut 403 contacts the upper surface of the annular convex hole provided on the corner bottom plate 102. After the rock fixing nut 403 is tightened, the rock fixing nut 403 is fixed to the corner bottom plate 102; the lower inner wall of the rock fixing expansion tube 402 is provided with a slope angle, which is installed on the outside of the rock fixing rod 401, and the upper part is in contact with the rock fixing nut 403; by tightening the rock fixing nut 403, the rock fixing rod 401 can be driven to rise, and the rock fixing expansion tube 402 is opened under the joint action of the fixing nut 403 and the slope angle of the lower inner wall to be fixed to the surrounding rocks.

[0023] During construction and installation, first place the bottom plate 1 on the rock surface, and adjust the angles of the central bottom plate 101 and the bottom plates 102 at the three corners around the bottom plate 102 to make the bottom plate 1 fit the rugged rock terrain.

[0024] Subsequently, the rock fixing rod 401 in the rock fixing system 4 is inserted into the circular hole opened on the corner bottom plate 102, and the rock fixing rod 401 is clamped by a drill rig and the upper part of the rock fixing rod 401, and the rock fixing rod 401 is driven by the drill rig to drill into the rock. The middle part of the rock fixing rod 401 is provided with a thread, and the rock fixing nut 403 is connected to the rock fixing rod 401 by a thread. The lower surface of the rock fixing nut 403 contacts the upper surface of the annular convex hole set on the corner bottom plate 102. After tightening the rock fixing nut 403, the rock fixing nut 403 is fixed to the corner bottom plate 102; the rock fixing expansion tube 402 has a slope angle on the lower inner wall, which is installed outside the rock fixing rod 401, and the upper part contacts the rock fixing nut 403; by tightening the rock fixing nut 403, the rock fixing rod 401 can be driven to rise, and the rock fixing expansion tube 402 is opened under the joint action of the fixing nut 403 and the slope angle of the lower inner wall, thereby achieving the fixation of the bottom plate 1 on the rock.

[0025] Then, the support length is adjusted through the slide grooves of the upper support rod 302 and the lower support rod 304 in the scaffolding support system 3, thereby controlling the inclination angle of the scaffolding fixing system 2 and the scaffolding bottom tube 5. The upper support rod 302 and the lower support rod 304 are fixed by the support rod tightening knob 303 to complete the adjustment of the scaffolding support angle.

[0026] Finally, the scaffolding bottom tube 5 is inserted into the scaffolding fixing system 2, and the tightening knob 205 is connected to the fixing sleeve 203 by threads. The inner part below the tightening knob 205 is provided with a slope angle. The tightening knob 205 is tightened so that it contacts the outer slope angle above the fixing clamp 204 during the process of rotating and descending. The further rotation and descent of the tightening knob 205 causes the outer wall of the fixing clamp 204 to contract, and finally the scaffolding bottom tube 5 is quickly clamped and fixed.
