[0002] With the development of social economy and the actual needs of social life, more and more projects are being built in mountainous areas. Mountainous areas are usually characterized by undulating terrain and steep slopes, which poses challenges to project construction. In addition, in order to protect the ecology and save construction costs, construction workers generally only perform simple treatment on rugged terrain and try to maintain the original terrain of the surface as much as possible, which poses further challenges to project construction.

[0003] In engineering, in most cases, scaffolding is needed to build longitudinal moving passages and working platforms for construction workers, and is also used to build peripheral safety nets. Scaffolding plays an important role in the construction and support of concrete formwork. However, 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 entire scaffolding system on mountainous rock slopes. At present, the commonly used solution in engineering is to cast steps on mountainous rock slopes so that the scaffolding has similar erection conditions as flat environments, but this method requires more construction time, and the erected scaffolding also lacks stability and cannot guarantee construction safety.

[0029] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] Please see attached Figure 1A scaffolding support device suitable for rock slope terrain includes a base plate 1, a scaffolding fixing system 2, a scaffolding support system 3, a rock fixing system 4 and a scaffolding bottom pipe 5; the scaffolding fixing system 2 is rotatably installed in the middle of the top surface of the base plate 1, and several groups of scaffolding support systems 3 are evenly distributed on the outside of the scaffolding fixing system 2 along the circumferential direction, and each group of scaffolding support systems 3 is movably connected between the scaffolding fixing system 2 and the base plate 1, and the lower end of the scaffolding bottom pipe 5 is vertically inserted into the scaffolding fixing system 2; one end of the rock fixing system 4 is connected to the base plate 1, and the other end of the rock fixing system 4 is drilled into the rock slope terrain. Several groups of rock fixing systems 4 are evenly distributed along the circumference of the base plate 1, so that the base plate 1 is set on the rock slope terrain.

[0031] The bottom plate 1 is fixed to the rock slope terrain through the rock fixing system 4, which can make the bottom plate 1 fit the rock slope terrain to the greatest extent, thereby providing a stable and reliable bottom support for the installation of the scaffold fixing system 2 and the scaffold bottom pipe 5. The scaffold fixing system 2 is rotated to a vertical state, and the scaffold supporting system 3 stably supports the scaffold fixing system 2, ensuring the vertical insertion of the scaffold bottom pipe 5, thereby ensuring the stability of the scaffold erection and use.

[0032] Preferably, three groups of scaffolding support systems 3 and rock fixing systems 4 are evenly spaced, and the number of groups of scaffolding support systems 3 and rock fixing systems 4 can also be increased or decreased according to actual use requirements.

[0033] Please see attached Figure 1 The base plate 1 includes a central base plate 101 and a corner base plate 102, and a plurality of corner base plates 102 are rotatably connected at the corners of the central base plate 101 through hinges; a scaffold fixing system 2 is installed in the middle of the central base plate 101, and the lower ends of a plurality of scaffold supporting systems 3 are respectively connected to a plurality of corner base plates 102, and a plurality of rock fixing systems 4 are respectively connected to a plurality of corner base plates 102.

[0034] Preferably, the number of corner base plates 102 is the same as the number of scaffolding support systems 3 and rock fixing systems 4 , that is, three groups, and can also be adaptively adjusted according to the number of scaffolding support systems 3 and rock fixing systems 4 .

[0035] Each corner base plate 102 can be independently rotated relative to the central base plate 101 through a rotating hinge, so that it can better adapt to the rugged rock slope terrain, fit on the surface of the rock slope terrain to the greatest extent, increase the contact area with the rock slope terrain, and thus ensure that the bottom support of the scaffold is stable and reliable.

[0036] Preferably, the central base plate 101 may adopt a hexagonal or quasi-hexagonal symmetrical structure, and the three corner base plates 102 are installed at equal intervals on the three sides of the central base plate 101 to ensure uniform force and stable support.

[0037] Please see attached Figure 1 The bottom surfaces of the central bottom plate 101 and the corner bottom plate 102 are provided with friction pads 103 , and the central bottom plate 101 and the corner bottom plate 102 are attached to the surface of the rock slope terrain through the friction pads 103 .

[0038] Preferably, the friction pad 103 can be made of materials such as rubber, which has good anti-slip and wear-resistant properties, and can further improve the installation stability of the base plate 1 on the rocky slope terrain, thereby ensuring the safety of erection and use of the scaffolding.

[0039] Please see attached Figure 1 To Attachment Figure 5 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 spherical shaft base 201 is fixedly installed at the center of the central base plate 101, and the lower ball shaft of the spherical shaft 202 is rotatably embedded in the upper ball groove of the spherical shaft base 201; the lower end of the fixing sleeve 203 is fixedly installed on the top of the spherical shaft 202, and the tightening knob 205 is movably connected in the fixing sleeve 203; the fixing clamp 204 is arranged in the fixing sleeve 203, and the scaffold bottom pipe 5 is inserted into the fixing clamp 204 and the tightening knob 205, and the fixing clamp 204 can be clamped on the scaffold bottom pipe 5; the upper end of the scaffold support system 3 is connected to the outer wall of the fixing sleeve 203.

[0040] By setting the spherical shaft base 201 and the spherical shaft 202, the fixed sleeve 203 can be flexibly rotated in multiple directions and angles, thereby ensuring the vertical stability of the fixed sleeve 203 when the base plate 1 is in an inclined state, and then being able to adapt to the insertion and fixation of the scaffolding bottom pipe 5 that needs to be vertically installed and bear loads.

[0041] Preferably, the bottom of the fixing clamp 204 can be fixed in the fixing sleeve 203, and through the cooperation between the fixing clamp 204 and the tightening knob 205, the fixing clamp 204 can be tightly clamped on the scaffolding bottom tube 5, so that the scaffolding bottom tube 5 can be stably inserted in the fixing sleeve 203 and will not fall out, thereby ensuring the stability of the scaffolding bottom on the rocky slope terrain.

[0042] Please see attached Figure 2 , Attachment Figure 3 and attached Figure 5The lower part of the locking knob 205 is formed with a first external thread 2051, and the top of the locking knob 205 is formed with a flange 2053; the upper part of the fixing sleeve 203 is formed with a first internal thread 2031, so that the locking knob 205 can be matched and screwed with the fixing sleeve 203 through the first internal thread 2031 and the first external thread 2051.

[0043] The tightening knob 205 is installed by screw thread, which is convenient for disassembly and adjustment. Under the transmission of the screw thread, the rotation of the tightening knob 205 can be converted into the axial linear motion of the tightening knob 205, so that the tightening knob 205 can cooperate with the clamping and releasing action of the fixing clamp 204.

[0044] Preferably, the outer diameter of the flange 2053 is larger than the outer diameter of the fixing sleeve 203 , which can prevent the tightening knob 205 from being screwed into the fixing sleeve 203 and unable to be removed, and also facilitates the hand-held rotating operation of the tightening knob 205 .

[0045] Please see attached Figure 2 , Attachment Figure 4 and attached Figure 5 An inner groove 2052 is formed on the inner wall at the bottom of the locking knob 205; the fixing clamp 204 includes a support plate 2041 and a plurality of clamping plates 2042 arranged on the support plate 2041 and enclosing a cylindrical structure, an outer groove 2043 is formed on the top outer wall of the clamping plate 2042, and the inner groove 2052 can slide against the outer groove 2043; an adjustment gap 2044 is left between two adjacent clamping plates 2042, so that the plurality of clamping plates 2042 can be deformed through the adjustment gap 2044 and clamped on the scaffolding bottom pipe 5.

[0046] When the tightening knob 205 is screwed downward into the fixed sleeve 203 through thread rotation, the inner bevel 2052 is slid downward to squeeze the inner bevel 2052, so that the multiple clamping plates 2042 gather inward and clamp onto the scaffolding bottom pipe 5. At this time, the adjustment gap 2044 is reduced, and the threaded engagement of the tightening knob 205 and the fixed sleeve 203 ensures that the multiple clamping plates 2042 have a clamping and locking effect on the scaffolding bottom pipe 5.

[0047] During disassembly, the fixing knob 205 is screwed out of the fixing sleeve 203, and the locking of the scaffolding bottom pipe 5 by the plurality of clamping plates 2042 is released, and the scaffolding bottom pipe 5 can be pulled out.

[0048] Preferably, four clamping plates 2042 can be arranged at equal intervals to ensure reliable clamping and locking of the scaffolding bottom pipe 5.

[0049] Please see attached Figure 1The scaffolding support system 3 includes a first ear plate 301, an upper support rod 302, a lower support rod 304 and a second ear plate 305; the first ear plate 301 is installed on the outer wall of the fixed sleeve 203, and the upper end of the upper support rod 302 is rotatably connected to the first ear plate 301 through a rotating shaft; the second ear plate 305 is installed on the corner base plate 102 of the base plate 1, and the lower end of the lower support rod 304 is rotatably connected to the second ear plate 305 through a rotating shaft; the upper support rod 302 is movably connected to the lower support rod 304.

[0050] The upper support rod 302 and the lower support rod 304 can rotate relative to the first ear plate 301 and the second ear plate 305 respectively through the rotating shaft, thereby rotating relative to the fixed sleeve 203 and the corner base plate 102, and can adapt to the angle base plate 102 tilted due to the rock slope terrain, and always maintain the vertical setting state of the fixed sleeve 203, so as to facilitate the vertical and stable insertion of the scaffolding bottom pipe 5, and can adapt to rock slope terrains of various angles.

[0051] The lower support rod 304 and the upper support rod 302 are both formed with long connecting grooves (not shown in the figure) along the length direction, and the support rod tightening knob 303 passes through the connecting groove to connect the lower support rod 304 and the upper support rod 302.

[0052] Preferably, the support rod locking knob 304 can be made of bolts and nuts, which can be moved through the long connecting groove and have a larger and more flexible adjustment space. After the bolts and nuts lock the upper support rod 302 and the lower support rod 304, the support reliability of the upper support rod 302 and the lower support rod 304 between the corner base plate 102 and the fixed sleeve 203 can be guaranteed.

[0053] Please see attached Figure 6 The rock fixing system 4 includes a rock fixing rod 401 and a rock fixing expansion tube 402; the rock fixing expansion tube 402 is sleeved on the rock fixing rod 401, the lower part of the rock fixing rod 401 is a drill bit and is drilled into the rock slope terrain, and the rock fixing expansion tube 402 is inserted into the rock slope terrain synchronously with the rock fixing rod 401; the upper part of the rock fixing rod 401 is installed on the corner base plate 102 through.

[0054] A drill bit of corresponding specifications can be selected as the rock fixing rod 401 according to the type of rock and the drilling rig, so as to facilitate drilling the rock fixing rod 401 into the rock, ensure the stable setting of the rock fixing rod 401 in the rock, and then ensure the setting stability of the entire device, and provide reliable vertical support for the scaffolding bottom pipe 5.

[0055] Please see attached Figure 6A second external thread 4011 is formed in the middle of the rock fixing rod 401, and the rock locking nut 403 is screwed on the rock fixing rod 401 through the second external thread 4011, and the bottom surface of the rock locking nut 403 is pressed tightly against the top surface of the corner bottom plate 102, and the top of the rock fixing expansion tube 402 is abutted against the bottom surface of the rock locking nut 403; a plurality of grooves 4021 are formed at intervals at the lower part of the rock fixing expansion tube 402, and a landslide surface 404 that matches and slides with each other is formed on the bottom inner wall of the rock fixing expansion tube 402 and the middle outer wall of the rock fixing rod 401.

[0056] Due to the setting of the landslide surface 404, the rock fixing expansion tube 402 is flush with the surface of the rock fixing rod 401 after being sleeved on the rock fixing rod 401, which facilitates the drilling of the rock fixing rod 401. At the same time, after the rock fixing rod 401 is lifted upward, it can squeeze the rock fixing expansion tube 402 through the landslide surface 404. Since the diameter of the rock fixing rod 401 below the landslide surface 404 is slightly larger than the diameter at the landslide surface 404, the rock fixing rod 401 expands the part of the rock fixing expansion tube 402 where the slot 4021 is set, so that the rock fixing rod 401 is tightened in the rock and is not easy to loosen, thereby ensuring the reliability of the bottom fixation.

[0057] When the rock fixing nut 403 is rotated, it cooperates with the second external thread 4011, so that the rock fixing rod 401 can move upward, thereby tightening in the rock, and can also move the rock fixing rod 401 downward to release the support for the rock fixing expansion tube 402, so as to facilitate the removal of the rock fixing rod 401. After the construction is completed and the scaffolding is removed, the rock fixing rod 401 can also be left in the rock to avoid the inconvenience of removal.

[0058] Preferably, the rock fixing nut 403 can be rotatably mounted on the corner base plate 102 via a rotating bearing to limit the axial movement of the rock fixing nut 403 so that the rock fixing rod 401 can be driven to perform axial linear movement when the rock fixing nut 403 rotates.

[0059] Please see attached Figure 1 To Attachment Figure 6 , the installation method and working principle of the utility model are:

[0060] The scaffold fixing system 2 is fixed at the center of the central base plate 101, and the scaffold supporting system 3 is connected to the fixing sleeve 203 of the scaffold fixing system 2 and the corner base plate 102 of the base plate 1 through the first ear plate 301 and the second ear plate 305, respectively. The rock fixing system 4 can pass through the corner base plate 102 through the through hole opened on the corner base plate 102. The corner base plate 102 is rotatably connected to the central base plate 101 through a rotating shaft hinge.

[0061] During installation, first adjust the angle of the hinge according to the rock slope terrain, so that the center base plate 101 and the corner base plate 102 can fit the installation surface to the greatest extent, thereby adapting to the rugged terrain, increasing the contact area with the rugged terrain of the slope, and increasing the friction between the device and the slope when it is affected by the upper gravity through the friction pad 103.

[0062] The lower part of the rock fixing rod 401 is a drill bit, and the drill rig can be matched and connected with the upper part of the rock fixing rod 401. The drill rig drives the rock fixing rod 401 to drill a hole in the rock. The middle part of the rock fixing rod 401 is threaded, and the rock fixing nut 403 is threadedly connected to the rock fixing rod 401. The rock fixing nut 403 is in contact with the corner bottom plate 102. The bottom inner wall of the rock fixing expansion tube 402 and the middle outer wall of the rock fixing rod 401 are provided with a landslide surface 404, and the rock fixing expansion tube 402 is sleeved on the rock fixing rod 401. By tightening the rock fixing nut 403, the rock fixing rod 401 is raised by thread transmission, and the rock fixing expansion tube 402 is restricted by the rock fixing nut 403, and is opened under the joint action of the slot 4021 and the landslide surface 404, and is tightly fixed to the surrounding rocks.

[0063] All rock fixing systems 4 are installed and fixed in the same manner, which will not be described in detail here.

[0064] The spherical shaft base 201 is fixed at the center of the central base plate 101, and the spherical shaft 202 is embedded in the spherical shaft base 201 to realize the rotation of the scaffold fixing system 2 relative to the base plate 1. The fixing sleeve 203 is fixed on the spherical shaft 202. The axial direction of the fixing sleeve 203 is adjusted to be in a vertical state by rotating the spherical shaft 202, thereby ensuring the vertical insertion and fixation of the scaffold bottom pipe 5.

[0065] The combined length of the upper support rod 302 and the lower support rod 304 is adjusted by sliding the support rod locking knob 303 along the connecting groove 306 on the upper support rod 302 and the lower support rod 304, and the angle of the upper support rod 302 relative to the fixed sleeve 203 and the angle of the lower support rod 304 relative to the corner base plate 102 are adjusted by the rotating shaft, thereby ensuring that several groups of scaffold support systems 3 support the fixed sleeve 203 in a vertical position.

[0066] The tightening knob 205 is connected to the fixing sleeve 203 by a thread. The tightening knob 205 is rotated to screw downward into the fixing sleeve 203, and the inner groove 2052 is used to slide and squeeze the outer groove 2043, so that the multiple clamping plates 2042 are squeezed inward and clamped to the scaffolding bottom pipe 5 inserted in the fixing clamp 204 and the tightening knob 205, thereby ensuring the vertical stable setting of the scaffolding bottom pipe 5.

[0067] The bottom of each scaffolding bottom tube 5 is vertically fixed by the base plate 1, the scaffolding fixing system 2, the scaffolding supporting system 3 and the rock fixing system 4, so that the entire scaffolding can be stably erected on the rocky slope terrain.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
