Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of scaffolds, in particular to a cantilevered steel disc-type outer scaffold. BACKGROUND

[0002] As an advanced construction facility combining cantilevered steel support and disc-type scaffold connection technology, the cantilevered steel disc-type outer scaffold plays an important role in the field of construction. With the continuous development of the construction industry, high-rise buildings, large-span structures and complex facade engineering are increasing, and such outer scaffolds are widely used in the construction of these high-difficulty projects due to their unique advantages, greatly improving the safety and efficiency of construction and making important contributions to the development of the construction industry.

[0003] In the existing installation of cantilevered steel disc-type outer scaffolds, the general method used is to use horizontal columns and vertical columns to build a basic frame, and the horizontal columns and vertical columns are arranged perpendicular to each other. In order to realize the connection of the two, a connecting disc is fixed on the vertical column, and a fixed buckle is arranged on the horizontal column. In the actual installation process, each horizontal column needs to be placed between two adjacent vertical columns first, and then the disc buckles at both ends of the horizontal column are respectively connected and fixed with the connecting discs on the adjacent vertical columns, thereby completing the connection between the horizontal column and the vertical column, and finally forming a complete outer scaffold structure. This installation method is relatively common in traditional construction, and many projects use this method to build cantilevered steel disc-type outer scaffolds.

[0004] However, the existing installation method has obvious defects. Since the horizontal column adopts a multi-section structure, it needs to be placed and connected and fixed with the vertical column section by section during installation, which makes the entire installation process extremely tedious, not only consuming a lot of time and manpower, but also reducing construction efficiency. SUMMARY

[0005] In order to reduce the complexity of the installation of the scaffold, the present application provides a cantilevered steel disc-type outer scaffold.

[0006] The present application provides a cantilevered steel disc-type outer scaffold, which adopts the following technical scheme:

[0012] The outer periphery of the connecting sleeve is provided with a connecting plate, which is symmetrically arranged on the upper and lower connecting plates, and the connecting plate is slidably inserted between the upper and lower connecting plates;

[0016] When the abutting plate is away from the connecting sleeve, the control assembly controls the plug-in column to be separated from the connecting hole.

[0017] By adopting the above technical scheme, the cantilever type steel disc buckle type outer scaffold can be used to cooperate the driving assembly and the control assembly to make the abutting plate abut against the connecting sleeve, and control the plug-in column to be inserted into the through hole after passing through the connecting hole, so as to realize convenient connection of the cross bar and the vertical bar, simplify the installation process, and facilitate subsequent disassembly.

[0018] Optionally, the control assembly includes a control wheel, a control spring, a control shaft, a control rope, a control gear and a control rack;

[0019] The control shaft is rotatably connected in the upper connecting plate, and the control wheel is arranged on the outer periphery of the control shaft;

[0020] The control rope is slidably arranged in the connecting plate, and the control rope is wound on the outer periphery of the control wheel, one end of the control rope is connected to the control wheel, and the other end of the control rope is connected to the plug-in column;

[0021] The control gear is arranged on the outer periphery of the control shaft, and the diameter of the control gear is smaller than the diameter of the control wheel;

[0022] The control rack is slidably connected to the connecting plate and the connecting sleeve, and the control rack is engaged with the control gear;

[0023] The control spring is arranged in the connecting plate, and the control spring drives the control rack to slide towards the horizontal rod, and at this time, the control wheel winds the control rope, and drives the inserting column to be separated from the connecting hole.

[0024] By adopting the above technical scheme, the control assembly composed of the control wheel, the control spring, the control shaft, the control rope, the control gear and the control rack can accurately control the plugging state of the inserting column and the connecting hole. When the abutting plate abuts against the connecting sleeve to align the inserting column and the connecting hole, the control assembly can control the inserting column to pass through the connecting hole and be inserted into the penetrating hole, so as to realize the connection and fixation of the horizontal rod and the vertical rod. When the abutting plate is away from the connecting sleeve, the control assembly can control the inserting column to be separated from the connecting hole, so as to facilitate the disassembly of the horizontal rod and the vertical rod and improve the convenience of the installation and disassembly of the scaffold.

[0026] The horizontal rod is formed with an accommodating groove extending in the circumferential direction on the outer peripheral side, the connecting sleeve slides in the connecting sleeve, and the driving plate is hinged to the horizontal rod and located in the accommodating groove;

[0027] When the driving plate is turned over towards the connecting sleeve, the abutting plate is pushed to abut against the inner peripheral side wall of the connecting sleeve;

[0028] The driving column is slidably connected to the horizontal rod and perpendicular to the horizontal rod, the driving column slides into the accommodating groove and abuts against the side of the driving plate away from the connecting sleeve;

[0031] By adopting the above technical scheme, the driving assembly can utilize the cooperation of the driving plate, the driving column, the driving worm wheel and the driving worm, so that the driving plate is turned over towards the connecting sleeve to push the abutting plate to abut against the inner peripheral side wall of the connecting sleeve. The limiting member can ensure the normal sliding of the driving column without rotation, so as to realize the effective abutment of the abutting plate to the connecting sleeve, enhance the connection stability between the horizontal rod and the connecting sleeve, facilitate the control of the connection state of the horizontal rod and the vertical rod, and simplify the installation process.

[0032] Optionally, the limiting member is a limiting column, the limiting column is arranged in the horizontal rod and perpendicular to the horizontal rod, and the driving column is slidably connected to the limiting column and coaxially arranged.

[0033] By adopting the above technical solution, the driving column is restricted by the limiting column, which restricts the rotation of the driving column and ensures that the driving column can slide stably, so that the driving component can work normally. This ensures that the clamping plate can smoothly clamp the connecting sleeve, and allows the control component to accurately control the insertion and removal of the plug-in column and the connecting hole, thereby improving the reliability and convenience of scaffolding installation and dismantling.

[0035] The abutment plate is slidably connected to a connecting block on the side away from the connecting sleeve, and the drive plate is hinged to the connecting block.

[0036] By adopting the above technical solution, the sliding connection of the drive block and the connecting block, as well as the corresponding hinge structure, can stably and efficiently convert the linear motion of the drive column into the flipping action of the drive plate, thereby pushing the clamping plate to reliably press against the inner circumferential side wall of the connecting sleeve, ensuring the connection stability between the crossbar and the connecting sleeve. At the same time, this structural design reduces the motion interference between the components and improves the smoothness of the external scaffolding assembly operation.

[0037] Optionally, the abutment plate has a slot on the side near the connecting sleeve, and there are multiple slots that are evenly spaced along the axial direction of the crossbar;

[0038] The inner circumferential sidewall of the connecting sleeve is slidably connected with a locking block corresponding to the abutment plate along a spiral trajectory. The abutment plate is inclined and symmetrically provided with guide surfaces, which guide the locking block to be inserted into the locking groove.

[0039] By adopting the above technical solution, setting up slots and blocks, and using guide surfaces to guide the blocks to accurately engage in the slots, the connection stability between the clamping plate and the connecting sleeve is increased, thereby improving the stability of the connection structure between the horizontal and vertical bars and enhancing the overall stability of the cantilevered steel disc-lock external scaffold.

[0040] Optionally, the crossbar is provided with guide posts extending axially, and there are multiple guide posts evenly spaced circumferentially, and the connecting sleeve slides on the guide posts.

[0041] By adopting the above technical solution, the guide post can make the connecting sleeve slide smoothly along the axial direction on the crossbar, ensuring accurate docking between the connecting sleeve and the connecting plate, thereby ensuring the smooth installation and connection of the crossbar and the vertical bar.

[0042] Optionally, a limit block is provided at the top of the plug post.

[0043] By adopting the above technical solution, the possibility of the plug pin falling off the connecting plate can be reduced when the horizontal bar and the vertical bar are connected, thus ensuring the stability and reliability of the connection.

[0056] The embodiment of the present application discloses a cantilever type steel disc buckle type external scaffold.

[0057] Embodiment one

[0058] With reference to Figure 1 The cantilever type steel disc-type outer scaffold provided by the embodiment of the present application comprises a cantilever module 1, vertical rods 2 and horizontal rods 3.

[0059] Specifically, the cantilever module 1 is fixedly installed on the outer wall of the building, and can be various structures suitable for cantilever support, such as steel beam structure or steel plate structure, etc. The cantilever module 1, as the basic support part of the entire outer scaffold, has sufficient strength and stability, and can bear the weight of the subsequent vertical rods 2, horizontal rods 3 and other components and the load in the construction process.

[0060] The vertical rods 2 are uniformly and spacedly fixed on the cantilever module 1, and the horizontal rods 3 are vertically arranged on the vertical rods 2. The horizontal rods 3 are multiple and uniformly and spacedly distributed along the axial direction of the vertical rods 2.

[0061] The vertical rods 2 are usually made of high-strength metal pipes, such as steel pipes, which have smooth surfaces and good corrosion resistance. The vertical rods 2 are uniformly and spacedly fixed on the cantilever module 1 by welding or bolt connection, etc. The spacing between the vertical rods 2 is ensured to be consistent during construction, thereby providing stable support points for the subsequent installation of the horizontal rods 3.

[0062] The horizontal rods 3 can also be made of metal pipes, such as aluminum alloy pipes, which have the characteristics of light weight and high strength. The horizontal rods 3 are arranged perpendicularly to the vertical rods 2, and are multiple and uniformly and spacedly distributed along the axial direction of the vertical rods 2, thereby forming a horizontal frame structure of the outer scaffold.

[0063] With reference to Figure 2 The vertical rods 2 are fixedly connected with connecting discs 21 on the outer circumferential side. The connecting discs 21 are generally circular metal discs, which are fixed on the outer circumferential side of the vertical rods 2 by welding. The connecting discs 21 are multiple and uniformly and spacedly arranged along the axial direction of the vertical rods 2, and each connecting disc 21 corresponds to one horizontal rod 3. The connecting disc 21 is provided with connecting holes 22, which extend along the vertical direction. The connecting holes 22 are multiple and uniformly and spacedly arranged along the circumferential direction.

[0064] The horizontal rods 3 are provided with accommodating grooves 32 on the outer circumferential side, which extend along the circumferential direction. The horizontal rods 3 are slidably sleeved with connecting sleeves 4, which are multiple and located in the accommodating grooves 32. The inner diameter of the connecting sleeves 4 is smaller than the outer diameter of the horizontal rods 3. The horizontal rods 3 are fixedly connected with guide columns 34, and the central axis of the guide columns 34 is parallel to the central axis of the horizontal rods 3. The guide columns 34 are located in the accommodating grooves 32, and are multiple and uniformly and spacedly arranged along the circumferential direction. The connecting sleeves 4 are slidably connected with the guide columns 34, thereby guiding the sliding direction of the connecting sleeves 4 and keeping the central axis of the connecting sleeves 4 coinciding with the central axis of the horizontal rods 3.

[0065] With reference to Figure 2 andFigure 3 The outer circumferential side of the connecting sleeve 4 is fixedly connected with the connecting plates 5, and the connecting plates 5 are two and symmetrically distributed upward and downward. The sliding of the connecting sleeve 4 on the cross rod 3 can conveniently adjust the relative position of the connecting sleeve 4 and the connecting disc 21, and facilitate the subsequent connecting operation of the connecting plates 5 and the connecting disc 21. The connecting plates 5 are generally rectangular metal plates, and the material thereof can be the same as that of the connecting sleeve 4.

[0066] Referring to Figure 4 and Figure 5 The upper connecting plate 5 is slidably connected with the insertion column 51, the insertion column 51 is generally a long strip square column metal rod, the top of the insertion column 51 is fixedly connected with the limiting block 511, the limiting block 511 is a square or circular block brick structure, which reduces the possibility that the insertion column 51 completely separates from the connecting plate 5 under the action of gravity. The lower connecting plate 5 is provided with the through hole 52, the through hole 52 is aligned with the insertion column 51, and the insertion column 51 passes through the through hole 52. When the insertion column 51 passes through the connecting hole 22 on the connecting disc 21 and is inserted into the through hole 52, the fixed connection of the cross rod 3 and the vertical rod 2 at this position is realized.

[0067] The outer circumferential side of the connecting sleeve 4 is fixedly connected with the connecting plates 5, and the connecting plates 5 are two and symmetrically distributed upward and downward. The sliding of the connecting sleeve 4 on the cross rod 3 can conveniently adjust the relative position of the connecting sleeve 4 and the connecting disc 21, and facilitate the subsequent connecting operation of the connecting plates 5 and the connecting disc 21. The connecting plates 5 are generally rectangular metal plates, and the material thereof can be the same as that of the connecting sleeve 4.

[0068] The cross rod 3 is provided with the driving assembly 6 for driving the abutting plate 31 to abut against the inner circumferential side wall of the connecting sleeve 4. Through the abutting connection of the abutting plate 31 and the inner circumferential side wall of the connecting sleeve 4, the sliding of the connecting sleeve 4 is limited, and the fixation of the connecting sleeve 4 is preliminarily realized.

[0069] Referring to Figure 5 and Figure 6 The driving assembly 6 includes the driving plate 61, the driving column 62, the driving worm wheel 63 and the driving worm 64. The driving plate 61 is hinged to the cross rod 3, and the driving plate 61 is located in the accommodating groove 32. The driving plate 61 is a circular arc plate structure, which can be flipped towards the direction close to or away from the central axis of the cross rod 3. When the driving plate 61 is flipped away from the central axis of the cross rod 3, the driving plate 61 first abuts against the abutting plate 31 and then pushes the abutting plate 31 to slide towards the connecting sleeve 4, so that the abutting plate 31 can abut against the inner circumferential side wall of the connecting sleeve 4. The side of the abutting plate 31 away from the inner wall of the connecting sleeve 4 is slidably connected with the connecting block 311, the connecting block 311 is a “T” block structure, and the side of the driving plate 61 away from the hinged connection point with the cross rod 3 is hingedly connected with the connecting block 311.

[0070] The driving column 62 is in a cylindrical structure, the driving column 62 is slidingly connected to the cross bar 3, the driving column 62 is multiple and uniformly spaced in the circumferential direction, the driving column 62 corresponds to the driving plate 61 one by one, and the driving column 62 is perpendicular to the cross bar 3. One end of the driving column 62 slides into the accommodating groove 32, and the driving plate 61 slidingly connected to the side away from the connecting sleeve 4 has a driving block 611, and the side away from the central axis of the cross bar 3 of the driving column 62 is hingedly connected to the driving block 611.

[0071] The driving worm gear 63 is threadedly connected to the outer circumferential side of the driving column 62, and the driving worm gear 63 is rotationally connected in the cross bar 3. The driving worm 64 is rotationally connected in the cross bar 3, and the driving worm 64 is engaged with the driving worm gear 63. The driving worm 64 and the cross bar 3 are in a coaxial state, and the side end surface of the driving worm 64 and the side end surface of the cross bar 3 are in the same vertical plane.

[0072] The cross bar 3 further comprises a limiting member for limiting the rotation of the driving column 62. The limiting member is a limiting column 33, which is in a square column structure, and the limiting column 33 is fixed in the cross bar 3 and perpendicular to the cross bar 3. The driving column 62 is slidingly connected to the limiting column 33 and coaxially arranged, and the driving column 62 corresponds to the limiting column 33 one by one. During use, the limiting column 33 limits the rotation of the driving column 62, and ensures that the driving column 62 slides linearly under the driving of the driving worm gear 63.

[0073] The end surface of the driving worm 64 is provided with a "cross" shaped driving groove, and a "cross" shaped tool is used to drive the driving worm 64 to rotate. When the driving worm 64 rotates, the driving worm 64 drives the driving worm gear 63 to rotate, and the rotation of the driving worm gear 63 causes the driving column 62 to slide in the direction perpendicular to the cross bar 3, thereby realizing the overturning of the driving plate 61.

[0074] The cross bar 3 is provided with a control assembly for controlling the insertion and disconnection of the plug-in column 51 in the connecting hole 22. Such structure cooperation makes the connection of the cross bar 3 and the vertical bar 2 more convenient, reduces the installation steps, and improves the installation efficiency.

[0075] Referring to Figure 5 With Figure 7 , the control assembly comprises a control wheel 71, a control spring 72, a control shaft 73, a control rope 74, a control gear 75 and a control rack 7. The control shaft 73 is rotationally connected in the upper connecting plate 5, and the control wheel 71 is fixedly connected to the outer circumferential side of the control shaft 73. The control rope 74 is slidingly arranged in the connecting plate 5, and the control rope 74 is wound around the outer circumferential side of the control wheel 71. One end of the control rope 74 is fixedly connected to the outer circumferential side wall of the control wheel 71, and the other end is fixedly connected to the vertical outer wall of the plug-in column 51.

[0076] The control gear 75 is fixedly connected to the outer circumferential wall of the control shaft 73, and the diameter of the control gear 75 is smaller than the diameter of the control wheel 71. The control rack 7 is slidingly connected to the connecting plate 5 and the connecting sleeve 4, and the control rack 7 is engaged with the control gear 75. The control rack 7 is fixedly connected with a stop block on the side away from the control gear 75, the stop block is slidingly connected to the connecting plate 5, and the control spring 72 is installed in the connecting plate 5, one end of the control spring 72 abuts against the stop block, and the other end abuts against the connecting plate 5.

[0077] When the abutting plate 31 is away from the connecting sleeve 4, the control spring 72 is elastically released to push the control rack 7 to slide towards the horizontal rod 3, at this time, the control rack 7 drives the control shaft 73 to rotate through the control gear 75, so that the control wheel 71 winds the control rope 74. When the control wheel 71 winds the control rope 74, the control column is pulled to slide upwards to be separated from the connecting hole 22. When the abutting plate 31 abuts against the connecting sleeve 4, the abutting plate 31 pushes the driving rack to slide away from the horizontal rod 3, the control rack 7 drives the control shaft 73 to rotate through the control gear 75, so that the control wheel 71 unwinds the control rope 74, at this time, the plug-in column 51 passes through the connecting hole 22 and the through hole 52 under the action of gravity, and the connection and fixation between the horizontal rod 3 and the vertical rod 2 are realized.

[0078] The implementation principle of the cantilever type steel disc buckle type outer scaffold of the embodiment one is as follows:

[0079] In the installation of the outer scaffold, the cantilever module 1 is first fixed, then the vertical rod 2 is installed, then the connecting sleeve 4 is sleeved on the horizontal rod 3 and slid to a suitable position, the connecting disc 21 is slid to be inserted between the upper and lower connecting plates 5, and the plug-in column 51 is aligned with the connecting hole 22. Then the driving worm 64 is rotated, the driving worm wheel 63 drives the driving column 62 to slide, the driving column 62 pushes the driving plate 61 to flip, the driving plate 61 pushes the abutting plate 31 to abut against the inner circumferential wall of the connecting sleeve 4. In the process that the abutting plate 31 abuts against the connecting sleeve 4, the control rack 7 moves to drive the control gear 75 and the control shaft 73 to rotate, the control wheel 71 releases the control rope 74, so that the plug-in column 51 is inserted into the through hole 52 after passing through the connecting hole 22, and the fixed connection between the horizontal rod 3 and the vertical rod 2 is realized. When it is necessary to disassemble, the driving worm 64 is reversely rotated to make the abutting plate 31 away from the connecting sleeve 4, the control spring 72 drives the control rack 7 to slide towards the horizontal rod 3, the control wheel 71 winds the control rope 74 to drive the plug-in column 51 to be separated from the connecting hole 22, and the disassembly is completed. Compared with the traditional installation mode, the structure design reduces the steps of installing the horizontal column and clamping in sections, greatly improves the installation and disassembly efficiency, and reduces the construction cost.

The clamping block 41 is slidably connected to the inner circumferential side wall of the connecting sleeve 4, the clamping block 41 slides along a spiral track, and the clamping block 41 corresponds to the abutting plate 31. The abutting plate 31 is provided with a guide surface 313 corresponding to the slot of the clamping groove 312, the guide surface 313 can be an inclined surface, and the guide surface 313 is used to guide the clamping block 41 to be clamped into the clamping groove 312. When the abutting plate 31 abuts against the connecting sleeve 4, the clamping block 41 is inserted into the clamping groove 312 under the action of the guide surface 313. When the clamping block 41 slides on the guide surface 313, the clamping block 41 slides on the connecting sleeve 4 under the action of the spiral track, so that the position of the clamping block 41 can be adjusted until the clamping block 41 is inserted into the clamping groove 312 when the clamping block 41 is aligned with the clamping groove 312. Further, the connection stability between the abutting plate 31 and the connecting sleeve 4 is enhanced, the loosening phenomenon of the abutting plate 31 in the use process is reduced, and the safety and reliability of the entire external scaffold are improved.
