Description

Technical Field

[0001] The invention relates to the technical field of scaffold engineering construction, in particular to a disc-type scaffold and an erection method thereof. Background Art

[0002] During the erection of exterior protection and operating platforms for construction projects, large openings are often required in the exterior scaffolding due to construction requirements, such as the installation of unloading platforms, the hoisting of large equipment, or the establishment of material transfer channels. These openings disrupt the scaffolding's integrity and continuity, weakening its load-bearing capacity and stability, necessitating reliable reinforcement measures. Currently, the commonly used method in the industry is to use fastener-type steel pipe scaffolding to reinforce the perimeter of these openings.

[0003] However, this traditional reinforcement method has exposed a series of serious technical flaws and safety hazards in practical application, especially when dealing with the large reserved openings required for large unloading platforms (often reaching widths of 3 meters or more). To span these large openings, the required horizontal crossbars or diagonal bracing steel pipes often need to be 6, 9, or even longer. The use of these extremely long steel pipes poses significant safety risks. First, due to their inherent weight and relatively low rigidity, they are prone to accidental bending, slipping, or external impact during installation, use, and subsequent dismantling. Once they fall from height, they pose a devastating threat to workers, equipment, and materials below, with unimaginable consequences. Second, when workers are handling, positioning, installing, and fastening these extremely long steel pipes at height, they must maintain an unstable posture at the edge of the opening or at temporary supports for extended periods of time while handling heavy objects. This significantly increases the risk of losing balance and stepping on empty space. Their difficult handling also significantly prolongs workers' exposure to high-risk areas.

[0004] In addition, the use of extra-long steel pipes for reinforcement also leads to low construction efficiency and operational difficulties. Extra-long steel pipes are extremely difficult to move, turn and accurately position in the narrow scaffolding space, and workers need to expend a lot of physical strength to coordinate and carry them. The installation process is time-consuming and labor-intensive, and it is difficult to ensure that the connection nodes (fasteners) are tightened in place at one time. Repeated adjustments are often required, which greatly slows down the construction progress. At the same time, the erection and dismantling of extra-long steel pipes requires a large operating space, which is often difficult to meet in a dense scaffolding environment, further increasing the difficulty of operation and safety risks.

[0005] In terms of structural performance, overlong steel pipes are more likely to experience excessive deflection when subjected to stress, especially eccentric or dynamic loads (such as when the unloading platform is subjected to impact). This not only affects the actual reinforcement effect, but can also cause abnormal stress on the connecting fasteners, generating additional bending moments, thereby reducing the reliability and durability of the entire reinforcement system and posing a potential collapse risk.

[0006] The CN222558105U utility model patent relates to a self-locking disc-type scaffolding fixing device, which includes a disc-type scaffolding fixing mechanism for fixing the scaffolding. The disc-type scaffolding fixing mechanism includes a steel pipe column, a mounting plate fixedly connected to the steel pipe column, and an adjustable steel pipe crossbar mechanism. The steel pipe crossbar mechanism includes a cross pipe body, and a rotating mounting seat is fixedly connected to the side of the cross pipe body.

[0007] The invention patent CN109488011B relates to a device for longitudinal connection of scaffolding steel pipes, in which a central nut is welded in the middle of the central screw, and a set of fastening devices are installed at both ends of the central screw; each set of fastening devices includes a circular steel plate, four arc-shaped clips, eight semicircular fasteners and a rotating shaft, the central circular hole of the circular steel plate passes through the central screw, and the four arc-shaped clips are evenly welded to the circular steel plate around the central circular hole of the circular steel plate, and each arc-shaped clip is connected to two semicircular fasteners through a rotating shaft; the upper part of the semicircular fastener is a semicircular hook, and the lower part is a gear that engages with the central screw; the ends of the four arc-shaped clips of each set of fastening devices are welded to the end circular steel plate, and the central circular hole of the end circular steel plate passes through the central screw and is fastened. Summary of the Invention

[0008] The object of the present invention is to provide a disc-type scaffold and an erection method thereof, so as to ensure that the scaffold frame body can continue to be erected upwards when the lower upright poles of the scaffold are disconnected.

[0009] The technical solution of the present invention to solve the above technical problems is as follows:

[0010] A disc-type scaffolding includes conventional vertical poles, multiple groups of horizontal poles and multiple groups of disc-type vertical poles vertically arranged on the horizontal poles. The bottoms of the conventional vertical poles are fixed to the ground, and the side ends of the conventional vertical poles are fixed to the building structure. The bottoms of the disc-type vertical poles are provided with bases, and the outer ends of the bases are provided with U-shaped clamping grooves for mounting the horizontal poles. The U-shaped clamping grooves have an open side and an arc-shaped inner surface matching the outer wall of the horizontal pole.

[0011] The end of the horizontal rod is provided with a horizontal rod U-shaped end, and the base is provided with a lock pin latch opening running through the interior thereof. A wedge-shaped lock pin is slidably passed through the lock pin latch opening, and the wedge-shaped lock pin forms a radial extrusion fit with the horizontal rod U-shaped end and the inner wall of the base respectively.

[0012] Furthermore, the U-shaped clamping groove includes two arc-shaped plates, one end of the two arc-shaped plates is hinged by a hinge, and the locking plates at the other end of the two arc-shaped plates are connected by bolts.

[0013] Furthermore, a connection between the base and the U-shaped clamping groove forms an arc-shaped transition portion, and the curvature radius R of the arc-shaped transition portion is ≥5mm.

[0014] Furthermore, vertical diagonal brace connecting screws for installing the scissors brace can be slidably provided on the side surface of the base.

[0015] Furthermore, a pole butt joint is provided at the bottom of the conventional pole.

[0016] A method for erecting a disc-type scaffold comprises the following steps:

[0017] S1. Set up two regular poles vertically on both sides of the scaffolding frame and fix the bottoms of the two regular poles on the ground.

[0018] S2. Anchor the connecting plates at the upper and lower ends of the conventional vertical poles to the building structure through wedge-shaped locking pins, horizontal rods and wall connecting pieces.

[0019] S3. Place the end of the horizontal rod in the U-shaped clamping groove of the buckled vertical rod, drive the wedge-shaped locking pin into the lock pin insertion hole of the base, and knock the wedge-shaped locking pin until its bottom surface presses against the U-shaped end surface of the horizontal rod.

[0020] S4. Insert the vertical diagonal brace connecting screw into the side hole of the base and pre-tighten it with a nut. Insert the upper end of the scissors brace into the screw and tighten the nut. Connect the lower end to the connecting plate at the lower end of the conventional vertical pole through a wedge-shaped locking pin.

[0021] S5. Insert the pole joint at the bottom of the upper conventional pole into the lower buckle pole and rotate to lock;

[0022] S6. Insert the pole joint at the bottom of the upper conventional pole into the lower conventional pole and rotate to lock;

[0023] S7. Place the end of the horizontal rod between the adjacent conventional vertical rods on the left and right, connect the U-shaped end of the horizontal rod to the connecting plate of the conventional vertical rod via a wedge-shaped locking pin, and strike the wedge-shaped locking pin until its bottom surface presses against the surface of the U-shaped end of the horizontal rod;

[0024] S8. Taking the opening of the first floor frame as the reference layer, repeat steps S6-S7 layer by layer from bottom to top, and perform verticality correction after each layer is erected.

[0025] The present invention has the following beneficial effects:

[0026] The U-shaped clamping groove on the base of the present invention has an arc-shaped inner surface that matches the outer wall of the horizontal rod, which can effectively fit the horizontal rod and provide stable support for the horizontal rod. The inclined surface of the wedge-shaped locking pin forms a radial compression fit with the U-shaped end of the horizontal rod and the inner wall of the base. Continuous tapping of the operating end causes the base and the U-shaped end of the horizontal rod to produce radial elastic deformation. This allows the scaffolding frame to continue to be erected even if the lower vertical poles are disconnected, ensuring the overall stability of the scaffolding structure.

[0027] The connection between the base and the U-shaped clamping groove forms an arc-shaped transition part, and the curvature radius has certain requirements. This design can reduce stress concentration, improve the strength and durability of the connection part, and is also conducive to the installation and adjustment of the horizontal rod.

DETAILED DESCRIPTION

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] In the present invention, the terms "longitudinal", "lateral", "vertical", "up", "down", "front", "back", "left", "right", "top", "bottom" and the like indicate directions or positional relationships based on the attached Figure 2 The orientation or positional relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0037] Please refer to Figure 1-2 In the actual application and erection process of the disc-type scaffolding, in order to ensure the stability, safety and convenience of its structure, the specific implementation method of the disc-type scaffolding is described in detail below.

[0038] A disc-type scaffolding comprises conventional vertical poles 100, multiple sets of horizontal poles 1, and multiple sets of disc-type vertical poles 2 vertically mounted on the horizontal poles 1. The bottoms of the conventional vertical poles 100 are fixed to the ground, and the side ends of the conventional vertical poles 100 are fixed to the building structure. The bottoms of the disc-type vertical poles 2 are provided with bases 3, and the outer ends of the bases 3 are provided with U-shaped clamping grooves 4 for mounting the horizontal poles 1. The U-shaped clamping grooves 4 have open sides and arc-shaped inner surfaces that match the outer walls of the horizontal poles 1. The ends of the horizontal poles 1 are provided with horizontal pole U-shaped ends 11. The bases 3 are provided with locking pin latch openings 6 extending therethrough. The locking pin latch openings 6 are slidably provided with wedge-shaped locking pins 5, which form radial extrusion fits with the horizontal pole U-shaped ends 11 and the inner wall of the base 3, respectively.

[0039] Conventional vertical poles 100 serve as the basic support structure of the scaffolding. Their bottoms are firmly fixed to the pre-buried steel plates in the ground through high-strength bolts to ensure that they will not move or tilt when bearing the overall weight of the scaffolding and construction loads. At the same time, in order to enhance the connection stability between the scaffolding and the building structure, conventional vertical poles 100 are anchored to the building structure through horizontal rods 1 and wall connectors. The wall connectors use a rigid connection method. For example, through bolt sleeves pre-buried in the building structure, high-strength bolts are used to tightly connect the horizontal rod 1 to the building structure, and then the horizontal rod 1 is fixed to the corresponding connecting plate 101 on the conventional vertical pole 100. The connecting plate 101 is provided with a plurality of holes that match the bolts. The connection position can be adjusted according to actual construction needs to ensure a reliable connection between the scaffolding and the building structure, effectively resisting wind loads and horizontal forces during construction.

[0040] The buckle upright 2 is vertically arranged on the horizontal rod 1 to provide vertical support for the scaffolding. A base 3 is provided at the bottom of the buckle upright 2. The base 3 is made of high-strength steel and has sufficient strength and rigidity to withstand the load transmitted by the horizontal rod 1. The outer end of the base 3 is provided with a U-shaped clamping groove 4 for mounting the horizontal rod 1. The U-shaped clamping groove 4 has an open side and an arc-shaped inner surface that matches the outer wall of the horizontal rod 1. The radius of curvature within the arc matches the outer diameter of the horizontal rod 1, ensuring that the horizontal rod 1 can fit tightly in the U-shaped clamping groove 4, reducing the shaking of the horizontal rod 1 in the U-shaped clamping groove 4 and improving the stability of the connection.

[0041] The base 3 is provided with a lock pin insertion opening 6 extending therethrough, into which a wedge-shaped lock pin 5 is slidably inserted. The wedge-shaped lock pin 5 is made of high-quality alloy steel and has high strength and wear resistance. The wedge-shaped lock pin 5 is wedge-shaped. When the wedge-shaped lock pin 5 is inserted into the lock pin insertion opening 6, the inclined surface of the wedge-shaped lock pin 5 forms a radial extrusion fit with the U-shaped end 11 of the horizontal rod and the inner wall of the base 3, respectively. This extrusion fit can generate a large extrusion force, firmly fixing the horizontal rod 1 in the U-shaped clamping groove 4, and preventing the horizontal rod 1 from loosening or falling off during use. In actual operation, after the end of the horizontal rod 1 is placed in the U-shaped clamping groove 4 of the disc buckle vertical rod 2, the wedge-shaped lock pin 5 is inserted into the lock pin insertion opening 6 of the base 3, and then the top of the wedge-shaped lock pin 5 is struck with a hammer until the bottom surface of the wedge-shaped lock pin 5 presses against the surface of the U-shaped end 11 of the horizontal rod, ensuring that the connection between the horizontal rod 1 and the disc buckle vertical rod 2 is firm and reliable.

[0042] Furthermore, the U-shaped clamping groove 4 includes two arc-shaped plates 41 , one end of the two arc-shaped plates 41 is hinged by a hinge 42 , and the locking plates 43 at the other end of the two arc-shaped plates 41 are connected by bolts.

[0043] The U-shaped clamping groove 4 comprises two curved plates 41, hinged at one end by hinges 42. This allows for easy opening and closing of the U-shaped clamping groove 4, facilitating the installation and removal of the horizontal rod 1. Locking plates 43 at the other ends of the two curved plates 41 are bolted together. When installing the horizontal rod 1, the rod 1 is first placed within the U-shaped clamping groove 4. The two curved plates 41 are then tightened by tightening the bolts, securing the rod 1 securely within the U-shaped clamping groove 4. The locking plates 43 are provided with multiple bolt holes, allowing the tightening of the bolts to be adjusted according to the diameter of the horizontal rod 1 and actual construction requirements, ensuring a secure and reliable connection.

[0044] Furthermore, an arc-shaped transition portion 7 is formed at the connection between the base 3 and the U-shaped clamping groove 4 , and the curvature radius R of the arc-shaped transition portion 7 is ≥5 mm.

[0045] The connection between the base 3 and the U-shaped clamping groove 4 forms a curved transition section 7 with a curvature radius R ≥ 5mm. This design avoids stress concentration at the connection and improves the overall strength and durability of the base 3 and the U-shaped clamping groove 4. When the scaffold is under load, the curved transition section 7 evenly distributes stress, reducing the risk of structural damage caused by localized excessive stress and extending the scaffold's service life.

[0046] Furthermore, a vertical diagonal brace connecting screw 8 for installing the scissors brace 9 can be slidably provided on the side surface of the base 3.

[0047] In order to further improve the stability of the scaffolding, the side of the base 3 is slidably provided with a vertical diagonal brace connecting screw 8 for installing the scissors brace 9. The vertical diagonal brace connecting screw 8 is made of high-strength threaded steel, and its surface is rust-proofed to improve its corrosion resistance. When installing the scissors brace 9, first insert the vertical diagonal brace connecting screw 8 into the side hole of the base 3 and pre-tighten it with a nut, then insert the upper end of the scissors brace 9 into the screw 8 and tighten the nut, and the lower end is connected to the connecting plate 101 at the lower end of the conventional vertical pole 100 through the wedge-shaped locking pin 5. The scissors brace 9 is made of steel pipe, and its two ends are provided with a connection structure that matches the wedge-shaped locking pin 5 or the vertical diagonal brace connecting screw 8. Through the setting of the scissors brace 9, the overall stability of the scaffolding can be effectively enhanced, lateral force can be resisted, and the scaffolding can be prevented from tilting or collapsing.

[0048] Furthermore, a pole butt joint 10 is provided at the bottom of the conventional pole 100 .

[0049] The bottom of the conventional vertical pole 100 is provided with a pole joint 10 for connecting the upper and lower adjacent conventional vertical poles 100 with the buckle vertical pole 2 or the adjacent conventional vertical pole 100. The pole joint 10 adopts a special structural design, and is provided with a slot inside thereof that matches the buckle vertical pole 2 or the conventional vertical pole 100, and the inner wall of the slot is provided with a positioning pin hole. When connecting the upper and lower adjacent conventional vertical poles 100 and the buckle vertical pole 2, or the adjacent conventional vertical poles 100, the pole joint 10 of the upper conventional vertical pole 100 is placed on the top of the lower buckle vertical pole 2 or the top of the conventional vertical pole 100, and the upper and lower vertical poles are firmly connected by a rotary locking device. This connection method is simple and convenient to operate, and can quickly achieve the connection and disassembly of the upper and lower vertical poles, thereby improving construction efficiency.

[0050] This specific embodiment also provides a method for erecting a disc-type scaffold, comprising the following steps:

[0051] S1. Two conventional vertical poles 100 are vertically set up on both sides of the scaffold frame, and the bottoms of the two conventional vertical poles 100 are fixed on the ground.

[0052] S2. Anchor the connecting plates 101 at the upper and lower ends of the conventional vertical pole 100 to the building structure through the wedge-shaped locking pin 5, the horizontal pole 1 and the wall connecting piece.

[0053] S3. Place the end of the horizontal rod 1 in the U-shaped clamping groove 4 of the buckled vertical rod 2, drive the wedge-shaped locking pin 5 into the lock pin insertion port 6 of the base 3, and knock the wedge-shaped locking pin 5 until its bottom surface presses against the surface of the U-shaped end 11 of the horizontal rod.

[0054] S4. Insert the vertical diagonal brace connecting screw 8 into the side hole of the base 3 and pre-tighten it with a nut. Insert the upper end of the scissors brace 9 into the screw 8 and tighten the nut. The lower end is connected to the connecting plate 101 at the lower end of the conventional vertical pole 100 through the wedge-shaped locking pin 5.

[0055] S5. Insert the pole joint 10 at the bottom of the upper conventional pole 100 into the lower buckle pole 2 and rotate to lock;

[0056] S6. Insert the pole joint 10 at the bottom of the upper conventional pole 100 into the lower conventional pole 100 and rotate and lock it;

[0057] S7. Place the end of the horizontal rod 1 between the adjacent conventional vertical rods 100 on the left and right. Connect the horizontal rod U-shaped end 11 of the horizontal rod 1 to the connecting plate 101 of the conventional vertical rod 100 via the wedge-shaped locking pin 5. Strike the wedge-shaped locking pin 5 until its bottom surface presses against the surface of the horizontal rod U-shaped end 11.

[0058] S8. Taking the opening of the first floor frame as the reference layer, repeat steps S6-S7 layer by layer from bottom to top, and perform verticality correction after each layer is erected.

[0059] First, prepare the site. In the scaffolding area, level and compact the ground to ensure it has sufficient load-bearing capacity. According to design requirements, mark the installation locations for the conventional uprights 100 on the ground, and pre-embed the steel plates that secure the bottoms of the conventional uprights 100. These plates are made of high-strength steel, with dimensions and thickness designed based on the scaffolding's load requirements. The pre-embedded depth is generally no less than 500mm to ensure a secure connection between the conventional uprights 100 and the ground.

[0060] Execute step S1 to vertically set up two conventional uprights 100 on both sides of the scaffold frame. The bottoms of the two conventional uprights 100 are firmly fixed to the pre-buried steel plates in the ground with high-strength bolts. During the fixing process, the verticality of the conventional uprights 100 is adjusted using a level and theodolite to ensure that the verticality deviation of the two conventional uprights 100 does not exceed the specified range. Generally, the verticality deviation should be controlled within H / 400 (H is the height of the conventional upright 100) to ensure the overall stability of the scaffold.

[0061] Proceed to step S2, anchor the connecting plates 101 at the upper and lower ends of the conventional vertical pole 100 to the building structure through the wedge-shaped locking pin 5, the horizontal rod 1 and the wall connecting piece. When installing the horizontal rod 1, first place the horizontal rod U-shaped end 11 at the end of the horizontal rod 1 into the corresponding slot of the connecting plate 101 of the conventional vertical pole 100, then insert the wedge-shaped locking pin 5 and knock it to form a radial extrusion fit with the horizontal rod U-shaped end 11 and the connecting plate 101, and firmly fix the horizontal rod 1 on the conventional vertical pole 100. At the same time, according to the design requirements, use the wall connecting piece to anchor the conventional vertical pole 100 to the building structure. The spacing and arrangement of the wall connecting pieces should comply with the relevant specifications to ensure a reliable connection between the scaffolding and the building structure, and effectively resist wind loads and horizontal forces during construction.

[0062] Execute step S3, place the end of the horizontal rod 1 in the U-shaped clamping groove 4 of the buckled vertical rod 2, drive the wedge-shaped locking pin 5 to penetrate the locking pin insertion port 6 of the base 3, and knock the wedge-shaped locking pin 5 until its bottom surface presses against the surface of the U-shaped end 11 of the horizontal rod. When placing the horizontal rod 1, ensure the horizontality of the horizontal rod 1 and use a spirit level to check and adjust it. When knocking the wedge-shaped locking pin 5, control the knocking force to avoid excessive knocking that may cause damage to the wedge-shaped locking pin 5 or the U-shaped end 11 of the horizontal rod. At the same time, check the extrusion fit between the wedge-shaped locking pin 5 and the U-shaped end 11 of the horizontal rod and the inner wall of the base 3 to ensure a firm and reliable connection.

[0063] Next, proceed to step S4, insert the vertical diagonal brace connecting screw 8 into the side hole of the base 3 and pre-tighten it with a nut, insert the upper end of the scissors brace 9 into the screw 8 and tighten the nut, and connect the lower end to the connecting plate 101 at the lower end of the conventional vertical pole 100 through the wedge-shaped locking pin 5. When installing the vertical diagonal brace connecting screw 8, ensure that the verticality and position of the vertical diagonal brace connecting screw 8 are accurate, and use a wrench to pre-tighten the nut. When installing the scissors brace 9, generally, the angle between the scissors brace 9 and the ground should be between 45°-60°, and the spacing of the scissors brace 9 should meet the design requirements. After the installation is completed, check the firmness of each connection part again to ensure that the scissors brace 9 can effectively enhance the overall stability of the scaffolding.

[0064] Proceed to step S5, insert the pole joint 10 at the bottom of the upper conventional pole 100 into the top of the lower layer buckle pole 2 and rotate and lock it. Ensure that the pole joint 10 and the top of the buckle pole 2 are tightly connected, and the connection between the upper conventional pole 100 and the lower layer buckle pole 2 is firm and reliable.

[0065] Then, step S6 is performed, where the pole joint 10 at the bottom of the upper conventional pole 100 is inserted into the lower conventional pole 100 and rotated to lock. The upper and lower conventional poles 100 are firmly connected by the rotation locking device. The tightening torque of the rotation locking device should meet the requirements of relevant specifications to ensure the safety and reliability of the connection.

[0066] During step S7, the wedge-shaped locking pin 5 connects the U-shaped end 11 of the horizontal rod 1 to the connecting plate 101 of the conventional vertical rod 100. Ensure that the horizontal rod 1 and the conventional vertical rod 100 are tightly connected. When placing the horizontal rod 1, ensure that it is level. When striking the wedge-shaped locking pin 5, control the force of the strike to avoid damage caused by excessive impact. Also, check the squeeze fit between the wedge-shaped locking pin 5, the U-shaped end 11 of the horizontal rod, and the inner wall of the base 3 to ensure a secure connection.

[0067] Finally, proceed to step S8. Using the first-floor frame opening as the reference layer, repeat steps S6 and S7 from bottom to top, performing verticality calibration after each layer is completed. Ensure that the installation position and connection security of components such as the horizontal rods 1 and conventional vertical rods 100 on each layer meet the requirements. After each layer is completed, use a spirit level and theodolite to calibrate the verticality of the scaffold. If verticality deviation exceeds the specified range, take timely adjustment measures, such as adjusting the tightness of the wedge-shaped locking pins 5, to ensure that the overall verticality of the scaffold meets the requirements and ensure construction safety.
