Description

Technical Field

[0001] This invention relates to the field of building construction scaffolding accessories technology, specifically a V-shaped cantilever bracket for scaffolding. Background Technology

[0002] In the field of building construction, scaffolding, as a core temporary support system for high-altitude operations, structural pouring, and exterior wall construction, is widely used in various construction scenarios such as high-rise buildings, municipal engineering, bridge renovation, and interior and exterior decoration. Cantilever supports are key auxiliary load-bearing components in the scaffolding system, mainly used in areas without ground support, such as cantilevered parts of building structures, wall sides, and beam / column edges, to achieve the outward extension of scaffolding. They can be equipped with casters for transporting goods. However, current scaffolding cantilever supports have some shortcomings, as follows:

[0003] Currently, most existing cantilever scaffolding supports adopt single straight-plate cantilever or right-angle L-shaped cantilever structures, resulting in a monotonous overall structural form. Firstly, traditional cantilever supports suffer from poor structural stability. The load-bearing capacity of straight-plate and L-shaped structures is concentrated, with the load mainly concentrated at the connection points between the support base and the wall or scaffolding uprights. This limits the vertical bearing capacity and horizontal anti-overturning ability. When subjected to loads from construction personnel, materials, equipment, and wind loads, problems such as support deformation, loosening, and displacement easily occur, seriously affecting the overall safety of scaffolding erection and posing significant construction safety hazards. They cannot meet the requirements of construction conditions involving large loads and high-altitude cantilevering. Furthermore, traditional cantilever supports often use full-span scaffolding or large steel trusses instead of conventional cantilever supports. Such erection methods consume a large amount of materials, have a long erection period, and are cumbersome to assemble and disassemble. Therefore, there is an urgent need for a V-shaped cantilever scaffolding support with excellent structural mechanical properties, strong bearing capacity, wide applicability, convenient assembly and disassembly, and reusability. Summary of the Invention

[0004] This invention provides a V-shaped cantilever support for scaffolding, which has the advantages of high-altitude cantilever construction, stable load-bearing capacity, convenient assembly and disassembly, high reusability, and long service life, thus solving the problems mentioned in the background art.

[0005] This invention provides the following technical solution: a V-shaped cantilever support for scaffolding, comprising a horizontal beam cantilever and scaffolding, wherein a mounting plate is fixedly provided at one end of the horizontal beam cantilever, and the mounting plate has mounting holes through which a hanging wheel can be installed; further comprising: an upper cantilever and a lower cantilever, one end of which is fixedly connected to one end of the horizontal beam cantilever; a connecting plate is fixedly provided at one end of each of the horizontal beam cantilever, the upper cantilever and the lower cantilever; connecting clamps are fixedly provided on the three connecting plates, and the three connecting clamps are installed on the same vertical rod of the scaffolding to form a triangular support, which can support the hanging wheel to complete the lifting of goods.

[0006] Preferably, the angle formed by the central axis of the crossbeam cantilever and the central axis of the upper cantilever is 43.8 degrees, the angle formed by the central axis of the crossbeam cantilever and the central axis of the lower cantilever is 53.5 degrees, and the angle formed by the central axis of the crossbeam cantilever and the central axis of the vertical bar of the scaffold is 90 degrees.

[0007] Preferably, the connecting clamp includes a fixed clamping plate, and a movable clamping plate is movably provided at one end of the fixed clamping plate via a shaft. A connecting bolt is movably provided at the other end of the fixed clamping plate via a shaft, and a locking nut is threaded onto the connecting bolt. The other ends of the fixed clamping plate and the movable clamping plate are locked together by the connecting bolt and the locking nut for clamping the scaffold.

[0008] Preferably, the inner side of the fixing clamp is provided with striped grooves to increase the edge of the fixing clamp, thereby slightly engaging the surface of the scaffold and increasing frictional resistance.

[0009] Preferably, the two ends of the crossbeam cantilever are provided with ventilation holes I, and one end of the upper cantilever and the lower cantilever is provided with ventilation holes II.

[0010] Preferably, the crossbeam cantilever, upper cantilever, and lower cantilever are made of seamless steel pipes, and all metal components are uniformly treated with hot-dip galvanizing.

[0011] Preferably, the vertical distance between the connecting clamp on the upper cantilever and the connecting clamp on the crossbeam cantilever is 500±3mm, and the vertical distance between the connecting clamp on the lower cantilever and the connecting clamp on the crossbeam cantilever is 705±3mm.

[0012] The present invention has the following beneficial effects:

[0013] 1. This invention sets up a V-shaped triangular support system composed of a horizontal cantilever, an upper cantilever, and a lower cantilever. The three members are clamped and fixed to the same vertical upright of the scaffolding through three sets of independent connecting clamps, forming a spatial triangular force-bearing structure. Unlike traditional single straight plate cantilever and L-shaped cantilever, this device disperses and transmits the vertical load, horizontal wind load, and torsional load from the hoisted goods from the outer end hanging wheel to three clamping points at different heights, instead of concentrating all stress at a single connection node. The triangular truss-type force transmission path can effectively decompose bending moment and shear force, greatly improving the overall vertical bearing capacity and horizontal anti-overturning and anti-torsional performance of the support. In the case of high-altitude material hoisting, it reduces the risk of support bending deformation and clamp loosening and displacement, significantly improves the safety redundancy of scaffolding cantilever hoisting operations, and can meet the construction needs of large-load material hoisting.

[0014] 2. The semi-tube clamps can be directly locked and fixed to the scaffolding uprights. Assembly and disassembly are completed simply by tightening the clamp bolts, requiring no on-site welding or modification of the scaffolding. It is compatible with most standard steel pipe scaffolding on the market. The device is modular, with simple component assembly and disassembly, minimal space occupation for transport and storage, and high versatility, adaptable to scaffolding conditions with different erection heights and upright spacing. The entire support system requires no additional pre-embedded components or anchoring to the building walls, relying entirely on the scaffolding uprights for load-bearing and fixation. It can be directly added to existing scaffolding systems, reducing on-site assembly difficulty for construction workers and effectively shortening on-site erection time.

[0015] 3. The inner side of the connecting clamp is machined with striped grooves. After the clamp grips the scaffold steel pipe upright, the edges of the striped grooves can slightly bite the outer wall of the steel pipe, greatly increasing the static friction coefficient between the clamp and the upright. Under vibration and impact loads, it effectively inhibits the clamp from slipping along the steel pipe upright, further ensuring the reliability of the entire set of support clamps. The clamp adopts a hinged opening and closing structure. During on-site installation, it is directly fastened to the outside of the upright. Turning the bolts and tightening the nuts completes the locking. During disassembly, the nuts can be loosened to directly remove the support. The installation and disassembly process is simple and does not require additional special tools. Ordinary wrenches can complete all operations, which facilitates rapid assembly, disassembly, and transportation on the construction site.

[0016] 4. This invention limits the included angle between the three rods and the vertical spacing of the clamps. The included angles of the rods of 43.8° and 53.5°, combined with the vertical spacing of the clamps of 500±3mm and 705±3mm, are the optimal geometric parameters obtained through mechanical simulation calculations and experimental verification. Under these parameters, the stress distribution inside the entire support is uniform, the maximum stress inside the rods is effectively reduced, and the material utilization rate is higher. It will not cause local crushing due to excessively small rod angles, nor will it cause single-point tensile overload of the upright due to excessively large angles. It maximizes the load-bearing performance while ensuring that the overall structural size is small and easy to transport. The standardized size also facilitates mass industrial production.

[0024] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-6 A V-shaped cantilever support for scaffolding includes a horizontal beam cantilever 1 and a scaffold 6. One end of the horizontal beam cantilever 1 is fixedly provided with a mounting plate 7, and the mounting plate 7 has mounting holes through which a hanging wheel can be installed. It also includes an upper cantilever 2 and a lower cantilever 3, one end of which is fixedly connected to one end of the horizontal beam cantilever 1. One end of the horizontal beam cantilever 1, the upper cantilever 2 and the lower cantilever 3 are all fixedly provided with a connecting plate 4. The three connecting plates 4 are fixedly provided with connecting clamps 5, and the three connecting clamps 5 are installed on the same vertical rod of the scaffold 6 to form a triangular support, which can support the hanging wheel to complete the lifting of goods.

[0026] In the actual production and manufacturing process, the connection between the crossbeam cantilever 1, upper cantilever 2, and lower cantilever 3 is preferably formed by full welding. After the welding operation is completed, all welds are ground and inspected to eliminate welding defects such as welding porosity, slag inclusion, and cracks, ensuring the strength of the welded joint. After welding, an integrated V-shaped triangular frame structure is formed. The connecting plate 4 is also fixed to the root end of the three rods by welding. The weld between the connecting plate 4 and the rod needs to be continuous and full. The connecting plate 4 serves as a transitional connection between the rod and the connecting fixture 5. The connecting plate 4 and the connecting fixture 5 can be fixed by welding or by detachable connection using high-strength bolts. When using detachable bolt connection, if a certain connecting fixture is worn and damaged later, the fixture can be replaced directly on site without scrapping the entire cantilever bracket, further improving the turnover life of the components and reducing the use cost.

[0027] By setting up a V-shaped triangular support system consisting of a horizontal cantilever 1, an upper cantilever 2, and a lower cantilever 3, the three members are clamped and fixed to the same vertical pole of the scaffolding through three sets of independent connecting clamps 5, forming a spatial triangular force-bearing structure. Unlike traditional single straight plate cantilever and L-shaped cantilever, this device disperses and transmits the vertical load, horizontal wind load, and torsional load from the hoisted goods from the outer end of the hanging wheel to three clamping points at different heights, instead of concentrating all stress at a single connection node. The triangular truss-type force transmission path can effectively decompose bending moment and shear force, greatly improving the overall vertical bearing capacity and horizontal anti-overturning and anti-torsional performance of the support. In the case of high-altitude material hoisting, it reduces the risk of support bending deformation and clamp loosening and displacement, significantly improves the safety redundancy of scaffolding cantilever hoisting operations, and can meet the construction needs of large-load material hoisting.

[0028] The angle between the central axis of the cantilever beam 1 and the central axis of the upper cantilever 2 is 43.8 degrees, and the angle between the central axis of the cantilever beam 1 and the central axis of the lower cantilever 3 is 53.5 degrees. The angle between the central axis of the cantilever beam 1 and the central axis of the vertical rod of the scaffold 6 is 90 degrees. Accurate selection of these angle parameters helps the finite element simulation software build a three-dimensional model, simulate the load input under hoisting conditions at the construction site, simulate vertical hoisting loads, horizontal wind loads, and torsional loads caused by the swinging of hoisted goods, and iterate and compare multiple angle schemes. If the angle is greater than this range, the upper and lower cantilever arms will be too gentle, significantly increasing the axial pressure inside the members and making them prone to instability. If the angle is less than this range, the upper and lower cantilever arms will be too steep, compressing the vertical distance between the upper and lower clamps. The load will be highly concentrated in a small section of the scaffold upright, causing local overload and posing a risk of bending deformation. After multiple rounds of simulation and physical load destructive tests, angles of 43.8° and 53.5° have been verified to allow for a more balanced distribution of internal forces among the three members, fully utilizing the material mechanical properties of the seamless steel pipe. Maintaining the horizontal beam cantilever extending 90° perpendicularly outward from the scaffold upright ensures the end mounting plate remains horizontal. After installing the lifting wheels, the wheel grooves remain vertical, ensuring the lifting ropes can move vertically up and down, preventing lateral deviation, deviation, and rope abrasion, thus ensuring the safety of lifting operations.

[0029] The connecting clamp 5 includes a fixed clamping plate 51, with a movable clamping plate 52 movably mounted on one end of the fixed clamping plate 51 via a shaft. A connecting bolt 53 is movably mounted on the other end of the fixed clamping plate 51 via a shaft, and a locking nut 54 is threaded onto the connecting bolt 53. The other ends of the fixed clamping plate 51 and the movable clamping plate 52 are locked together by the connecting bolt 53 and the locking nut 54, used to clamp the scaffolding 6. Both the fixed clamping plate 51 and the movable clamping plate 52 are made of cast steel, possessing high strength and toughness to prevent breakage under stress. The inner diameter formed by the fixed clamping plate 51 and the movable clamping plate 52 matches the outer diameter of the national standard scaffolding steel pipe, suitable for φ48.3mm standard scaffolding steel pipe uprights. The side-hinged movable clamp 52 allows the clamp to open like a snap-fit. During construction, the clamp is directly fastened to the outside of the scaffold upright, the movable clamp 52 is rotated to engage the steel pipe, and the hinged connecting bolt 53 is rotated into the outer slot of the movable clamp. The locking nut 54 is then tightened, and the fixed clamp 51 and movable clamp 52 grip the scaffold upright, completing the clamping and fixing. During disassembly, the locking nut 54 is loosened in the opposite direction, the connecting bolt 53 is turned out of the slot, the movable clamp 52 is lifted, and the entire set of supports can be directly removed from the scaffold upright. The entire set of clamps does not require disassembly of parts, and the hinged structure ensures that no parts are scattered or lost. In the complex environment of the construction site, small parts will not be lost and components will not be scrapped, facilitating on-site management.

[0030] The inner side of the fixing clamp 51 is provided with striped grooves 55 to increase the edge of the fixing clamp 51, thereby slightly biting the surface of the scaffolding 6 and increasing the frictional resistance. The striped grooves 55 are multiple parallel grooves along the inner circle of the clamp, and the edges of the grooves form hard edges. When the locking nut applies preload, the clamp grips the steel pipe upright, and the edges will slightly press into the outer surface of the steel pipe, forming a mechanical interlocking effect. Relying solely on the friction between the smooth clamp and the steel pipe, under the action of on-site vibration and hoisting impact loads, the clamp... There is a risk of slippage along the steel pipe; after setting the striped groove, in addition to friction, mechanical interlocking resistance is increased, providing double protection and effectively eliminating the hidden danger of clamp slippage failure; at the same time, the striped groove can destroy the oxide film of the galvanized layer on the outer wall of the steel pipe, eliminating the slippage problem caused by the smooth galvanized surface, and further improving the clamping reliability; it should be noted that the depth of the striped groove should not be too large, only surface interlocking is done, and the steel pipe wall should not be deeply cut to avoid excessive damage to the wall of the scaffolding upright and affecting the strength of the scaffolding upright itself.

[0031] Ventilation holes I8 are provided at both ends of the crossbeam cantilever 1, and ventilation holes II9 are provided at one end of the upper cantilever 2 and lower cantilever 3. All crossbeam cantilever, upper cantilever, and lower cantilever are made of seamless steel pipes, which are tubular hollow components. Subsequent hot-dip galvanizing for corrosion protection is required. If the steel pipe is a completely closed cavity, when immersed in high-temperature zinc liquid, the air inside the cavity will expand rapidly due to heat, increasing the internal pressure and causing bulging of the pipe wall. In extreme cases, the pipe wall may burst, resulting in workpiece damage or even a processing safety accident. Ventilation holes I8 and II9 provide gas flow channels within the steel pipe cavity during hot-dip galvanizing. The air that expands due to heat inside the pipe can be discharged out through the vent holes, and a small amount of molten zinc can also flow into the pipe. The inner wall of the steel pipe can be evenly coated with a zinc layer. When cooling, the air inside the pipe can also enter and exit through the vent holes, preventing the steel pipe from deforming due to negative pressure caused by temperature changes. The diameter of the vent holes does not need to be too large, just enough to meet the exhaust requirements. During processing, drilling can be used to drill directly into the steel pipe wall. After the support is put into use on the construction site, the vent holes can also play a drainage role. Rainwater can flow out through the vent holes after entering the inner cavity of the steel pipe, preventing long-term water accumulation inside the steel pipe cavity, preventing the inner wall of the steel pipe from rusting from the inside, and further extending the service life of the component.

[0032] The cantilever beam 1, upper cantilever 2, and lower cantilever 3 are made of seamless steel pipes, and all metal components undergo hot-dip galvanizing treatment. Compared with welded steel pipes, seamless steel pipes have no weld defects in the pipe wall, resulting in higher overall strength and better resistance to bending and torsion, making them suitable as load-bearing cantilever members. National standard Q355 seamless steel pipes are preferred, but Q235 steel pipes can also be selected depending on the working conditions. All metal components, including the three cantilever members, connecting plates, a complete set of connecting clamps, bolts, and nuts, undergo hot-dip galvanizing for corrosion protection. The hot-dip galvanizing process involves degreasing and pickling the components. After plating, the component is immersed in molten zinc, forming a zinc-iron alloy coating on the surface. Compared with the common spray painting and anti-rust paint used on construction sites, hot-dip galvanizing has strong adhesion and uniform coating thickness. It can form a protective layer on the edges, gaps, and inner walls of steel pipes, and can provide rust protection for many years in open-air construction environments. Even after repeated handling and impacts, even if the coating is worn in some areas, the zinc layer can still provide rust protection to the steel through electrochemical protection, greatly increasing the number of times the component can be reused and reducing the cost of frequent replacement of parts. This meets the needs of component reuse in the construction industry.

[0033] The vertical distance between the connecting clamp 5 on the upper cantilever 2 and the connecting clamp 5 on the crossbeam cantilever 1 is 500±3mm, and the vertical distance between the connecting clamp 5 on the lower cantilever 3 and the connecting clamp 5 on the crossbeam cantilever 1 is 705±3mm. 500mm and 705mm are the vertical installation distances of the three sets of clamps on the scaffold uprights. ±3mm is a manufacturing tolerance. In industrial mass production, due to the influence of cutting and welding processes, slight fluctuations in dimensions are allowed, but they cannot exceed the tolerance range. If the actual dimensions exceed the upper tolerance limit, the total height of the entire support will be too large, the overall volume will increase, and the space occupied during transportation and stacking will significantly increase. Simultaneously, this will affect the disc buckles on the scaffold uprights. The requirements for avoiding fastener positions are higher, and the adaptability to the construction site is reduced. If the size is smaller than the lower limit of the tolerance, the vertical distance between the three sets of clamps is too small, the load is concentrated, and the local compressive stress of the scaffold uprights is too large, which will cause local dents and bending deformation of the uprights. This size, together with the included angle of the members, constitutes the geometric reference of the whole set of supports, ensuring that the load can be evenly distributed to the three clamping points at different heights of the scaffold uprights. The upper clamp mainly bears the tensile force, the lower clamp mainly bears the compressive force, and the clamp at the root of the cantilever of the middle crossbeam bears both shear force and bending moment. The three points work together to transform the huge bending moment at the cantilever end into tensile and compressive forces at different heights on the uprights, which greatly improves the stress conditions.

[0034] Working principle: After the scaffolding is erected at the construction site, a complete vertical pole on the scaffolding is selected as the load-bearing base. The V-shaped cantilever bracket is moved to the installation position. The movable clamps 52 of the three sets of connecting clamps 5 are opened in sequence. The three sets of clamps are fastened and fitted onto the corresponding height positions of the same vertical pole of the scaffolding 6. The vertical distances of the upper cantilever 2 clamp, the crossbeam cantilever 1 clamp, and the lower cantilever 3 clamp on the pole meet the dimensional requirements of 500±3mm and 705±3mm, respectively. The movable clamps 52 are fastened and the connecting bolts 53 are inserted into the slots of the movable clamps 52. The locking nuts 54 on the three connecting clamps 5 are tightened in sequence with a wrench. The locking nuts 54 push the movable clamps 52 to press against the outer wall of the scaffolding pole. The inner striped grooves 55 of the fixed clamps 51 engage with the outer wall of the steel pipe. The entire bracket is firmly fixed to the scaffolding pole by the clamping force.

[0035] At this time, the horizontal beam cantilever 1 remains horizontally outward cantilevered. The horizontal beam cantilever 1, upper cantilever 2, and lower cantilever 3 together form a stable spatial triangular support system. The three sets of connecting clamps 5 respectively transfer the load of the support to three different height points of the scaffold uprights, converting the bending moment at the cantilever end into tension, compression, and shear force on the uprights. Then, on the mounting plate 7 at the end of the horizontal beam cantilever 1, a hanging wheel is assembled using the mounting holes, and a hoisting rope is threaded through it. The hanging wheel can then be used to realize the vertical hoisting operation of construction materials.

[0036] When hoisting goods, the downward load of the goods' own weight is transferred to the mounting plate 7 through the hoisting wheel, and then transmitted to the cantilever beam 1. Part of the load is directly transferred to the scaffold uprights through the connecting plate 4 and connecting clamp 5 at the root of the cantilever beam 1; another part of the load is distributed and transferred to the upper cantilever 2 and the lower cantilever 3. The upper cantilever 2 mainly bears the tensile force, transferring the load upward to the upper connecting clamp, generating an upward tensile force on the uprights; the lower cantilever 3 mainly bears the compressive force, transferring the load downward to the lower connecting clamp, applying downward compressive force to the uprights. The three points work together to bear the load, offsetting most of the overturning moment caused by the cantilever. When encountering strong winds, or when the hoisted goods swing and generate lateral torsional force, the triangular structure can also effectively resist lateral forces and suppress the torsional displacement of the support.

[0037] After the support frame is used, loosen the locking nuts 54 of the three sets of connecting clamps 5 in sequence, turn the connecting bolts 53 out of the slots of the movable clamp 52, and lift the movable clamp 52 outward. The entire support frame can then be directly removed from the scaffolding uprights without disassembly. It can be transported as a whole to the next construction project for storage and backup. During later maintenance, check whether the plating of the components is intact, whether the welds are cracked, whether the clamps open and close properly, and whether the threads are intact. If the components are undamaged, they can be put back into use directly.

[0038] The entire support system does not require anchoring to the building walls or floors, does not require pre-embedded bolts, does not damage the main structure of the building, and is installed entirely by attaching to the existing scaffolding uprights. It can be assembled simultaneously during the scaffolding erection stage or added later to the existing scaffolding that has already been erected, making it suitable for various exterior wall construction and material hoisting scenarios.
