Description

Technical Field

[0001] This utility model relates to the field of modular scaffolding technology, specifically to modular scaffolding suitable for super high-rise buildings and its erection and dismantling device. Background Technology

[0002] Scaffolding poles serve as construction platforms for super high-rise buildings. During construction, the efficiency of scaffolding erection, structural stability, and ease of dismantling directly affect the construction progress. Currently, the mainstream scaffolding poles on the market are traditional steel pipe coupler type and disc coupler type. During the erection of traditional steel pipe coupler type and disc coupler type scaffolding poles, multiple horizontal and vertical poles need to be transported and spliced ​​individually. The splicing process is cumbersome and relies on the experience of construction workers. During dismantling, each pole needs to be disassembled, which is time-consuming and labor-intensive.

[0003] Therefore, a modular scaffolding and its erection and dismantling device suitable for super high-rise buildings is proposed to solve the problems mentioned above. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a modular scaffolding and its erection and dismantling device suitable for super high-rise buildings. Through modular design, during installation, it eliminates the need to transport multiple members individually. Simultaneously, adjustable connecting flanges drive the lateral crossbars to unfold, which are then locked using fixing pins and locking slots. During lateral splicing, repeated manual adjustments to alignment are unnecessary. The three-lobed fixing flange assembly, in conjunction with the threaded rod, lifts the connecting flange and lateral crossbars. Combined with the locking action of the fixing slots and baffles, the lateral crossbars are fixed in a contracted state. During dismantling, the second scaffolding pole, along with multiple lateral crossbars, can be removed together, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: it includes a No. 1 scaffold pole, a No. 2 scaffold pole, and a fixing pin. The No. 1 scaffold pole is provided with a top connecting plate at its top and a lower connecting plate at its lower side. A snap-fit ​​plate is fixedly connected to the outer side of the No. 1 scaffold pole. The No. 2 scaffold pole is also provided with the top connecting plate, the lower connecting plate, and the snap-fit ​​plate.

[0006] The outer side of the second scaffold pole is also slidably fitted with a connecting flange, and the connecting flange is hinged with three lateral crossbars. The two adjacent lateral crossbars are arranged at a 90-degree angle. Both ends of the lateral crossbars are provided with a first-order snap-fit ​​groove that matches the fixing pin. The surface of the snap-fit ​​plate is provided with multiple second-order snap-fit ​​grooves. The distance from the end of the lateral crossbar to the hinge point is greater than the distance from the lower side of the lateral crossbar to the hinge point.

[0007] Preferably, both the No. 1 scaffold pole and the No. 2 scaffold pole are fixedly connected to an insertion rod on the side near the lower connecting plate. The upper surface of the top connecting plate is provided with a cross groove, and the lower surface of the lower connecting plate is provided with a cross protrusion.

[0008] A modular scaffolding erection and dismantling device suitable for super high-rise buildings includes a fixing flange assembly and multiple threaded rods. The fixing flange assembly is sleeved on the outer side of the second scaffold pole and is detachably connected to the second scaffold pole. The fixing flange assembly includes a first fixing component, a second fixing component, and a third fixing component. The first fixing component is hinged to the second fixing component, the second fixing component is hinged to the third fixing component, and the first fixing component and the third fixing component are fixedly connected by bolts on the side away from the second fixing component.

[0009] Preferably, the outer surfaces of the first, second, and third fixing components are all provided with fixing grooves, and two adjacent fixing grooves are arranged at a 90-degree angle.

[0010] Preferably, sleeves are fixedly connected to the outer surfaces of the first and third fixing components, and multiple lead screws pass through the sleeves. Multiple lead screw connection holes are opened on the upper surface of the connecting flange, and the ends of the lead screws are threadedly connected to the lead screw connection holes.

[0011] Preferably, the outer side of the second scaffold pole is provided with a fixing ring, which is engaged with the inner side of the fixing flange assembly.

[0012] Preferably, a baffle is rotatably connected to the opening side of the fixing slot, and the baffle is used to lock the lateral crossbar.

[0013] Compared with the prior art, this utility model provides a modular scaffolding and its erection and dismantling device suitable for super high-rise buildings, which has the following beneficial effects:

[0014] 1. Through modular design, there is no need to transport multiple rods individually during installation. At the same time, the lateral crossbars are unfolded by the adjustable connecting flange and locked by the fixing pin and the snap-fit ​​groove. There is no need to manually adjust the alignment repeatedly during horizontal splicing, which further reduces the difficulty of operation.

[0015] 2. By using the three-part fixed flange assembly and the screw rod, the connecting flange and the side crossbar are lifted. With the locking action of the fixed groove and the baffle, the side crossbar can be fixed in the contracted state. During dismantling, the No. 2 scaffold pole and multiple side crossbars can be removed together. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1:

[0025] Please see Figure 1 - Figure 2The modular scaffolding applicable to super high-rise buildings in this embodiment includes a first scaffold pole 1, a second scaffold pole 2, and fixing pins 3. The first scaffold pole 1 has a top connecting plate 4 at its top and a lower connecting plate 5 on its lower side. A snap-fit ​​plate 7 is fixedly connected to the outer side of the first scaffold pole 1. The second scaffold pole 2 also has a top connecting plate 4, a lower connecting plate 5, and a snap-fit ​​plate 7. A connecting flange 8 is also slidably fitted on the outer side of the second scaffold pole 2. Three lateral crossbars 9 are hinged to the connecting flange 8. The lateral crossbars 9 are arranged at a 90-degree angle. Both ends of the lateral crossbars 9 are provided with a first-order snap-fit ​​groove 10 that matches the fixing pin 3. The surface of the snap-fit ​​plate 7 is provided with multiple second-order snap-fit ​​grooves 11. The first-order scaffold poles and the second-order scaffold poles are arranged alternately. After the crossbar of the second-order scaffold pole is laid flat, it rests on the snap-fit ​​plate 7 of the first-order scaffold pole. The fixing pin 3 passes through the first-order snap-fit ​​groove 10 of the crossbar and through the second-order snap-fit ​​groove 11. After the second-order scaffold pole 2 is unfolded and connected by the fixing pin 3, multiple first-order scaffold poles 1 and second-order scaffold poles 2 are connected to each other.

[0026] Insertion rods 12 are fixedly connected to the side of scaffold pole 1 and scaffold pole 2 near the lower connecting plate 5. The upper surface of the top connecting plate 4 is provided with a cross groove 13, and the lower surface of the lower connecting plate 5 is provided with a cross protrusion. Insertion rods 12 are inserted into the top of scaffold pole 1 and scaffold pole 2. Rotating the upper scaffold pole aligns the cross protrusion of the lower connecting plate 5 with the cross groove 13 of the top connecting plate 4 and engages them. The top connecting plate 4 and the lower connecting plate 5 are provided with multiple bolt holes. After the top connecting plate 4 and the lower connecting plate 5 are aligned, they are connected by bolts.

[0027] A connecting flange 8 is also slidably fitted on the outer side of the second scaffold pole 2. The connecting flange 8 can slide up and down along the outer side of the second scaffold pole and can rotate around the second scaffold pole. During installation, the connecting flange 8 can be rotated to align the lateral crossbar 9 with the adjacent scaffold pole.

[0028] The distance from the end of the lateral crossbar 9 to the hinge point is greater than the distance from the lower side of the lateral crossbar 9 to the hinge point. The end of the lateral crossbar 9 is the end of the lateral crossbar 9 closest to the second scaffold pole, and the lower side of the lateral crossbar 9 is the side of the lateral crossbar 9 closest to the clamping plate 7. When multiple lateral crossbars 9 are unfolded and connected to adjacent scaffold poles, the lower side of the lateral crossbar 9 contacts the upper surface of the clamping plate 7. When a single lateral crossbar 9 rotates around the hinge point, it needs to drive the connecting flange 8 and the other lateral crossbars 9 connected to the connecting flange 8 to move upward. It is difficult for a single lateral crossbar 9 to rotate around the hinge point, thus avoiding the connection from disengaging.

[0029] Furthermore, both ends of the lateral crossbar 9 are provided with a first-order locking groove 10 that is adapted to the fixing pin 3, and the surface of the locking plate 7 is provided with multiple second-order locking grooves 11. The fixing pin 3 passes through the first-order locking groove 10 and the second-order locking groove 11 to further fix the lateral crossbar 9. When the lateral crossbar 9 is subjected to horizontal tension, the horizontal tension is transmitted to the fixing pin 3. The surface of the fixing pin 3 is in contact with the inner side of the first-order locking groove 10 and the second-order locking groove 11. When the fixing pin 3 is not damaged, the lateral crossbar 9 will not move horizontally.

[0030] The working principle of the above embodiment is as follows: Scaffold pole 1 and scaffold pole 2 are arranged alternately and connected to each other. Scaffold pole 1 and scaffold pole 2 are initially positioned by inserting rods 12, and their coaxiality is calibrated by the cooperation of cross protrusions and cross grooves 13. The top connecting plate 4 and the lower connecting plate 5 are vertically rigidly fixed by bolts. The connecting flange 8 drives the lateral horizontal bar 9 to unfold. The lower side of the horizontal bar fits against the snap-fit ​​plate 7 of the adjacent vertical pole for support. The fixing pin 3 passes through the snap-fit ​​grooves 11 of the first and second vertical poles to secure the horizontal bar. For horizontal locking, when using the system, first fix the bottom scaffold pole 1 to the ground or construction platform using the embedded parts. Then insert the insertion rod 12 of the top scaffold pole 2 into the bottom top connecting plate 4. Rotate the top scaffold pole to make the cross protrusion engage with the cross groove 13. After aligning the bolt holes, tighten the bolts. Slide and rotate the connecting flange 8 to align the three lateral horizontal bars 9 with the adjacent scaffold pole locking plates 7. Place the horizontal bars on the locking plates 7 and insert the fixing pins 3 to complete the horizontal connection. Repeat the above steps to complete the erection of multi-layer scaffold poles.

[0031] Example 2:

[0032] Please see Figure 3 - Figure 5 The modular scaffolding erection and dismantling device for super high-rise buildings in this embodiment includes a fixing flange assembly 14 and multiple threaded rods 15. The fixing flange assembly 14 is sleeved on the outer side of the second scaffold pole 2, and the fixing flange assembly 14 is detachably connected to the second scaffold pole 2. The fixing flange assembly 14 includes a first fixing member 1401, a second fixing member 1402, and a third fixing member 1403. The first fixing member 1401 is hinged to the second fixing member 1402, and the second fixing member 1402 is hinged to the third fixing member 1403. The first fixing component 1401 and the third fixing component 1403 are fixedly connected by bolts on the side away from the second fixing component 1402. The first fixing component 1401, the second fixing component 1402 and the third fixing component 1403 can rotate relative to each other. When the first fixing component 1401, the second fixing component 1402 and the third fixing component 1403 are unfolded, they can be fitted onto the outer side of the second scaffold pole. After the bolt side of the first fixing component 1401 and the third fixing component 1403 is locked, the fixing flange assembly 14 is fixed to the outer side of the second scaffold pole 2.

[0033] Fixing slots 16 are provided on the outer surfaces of fixing component 1401, fixing component 1402, and fixing component 1403. The two adjacent fixing slots 16 are arranged at a 90-degree angle. The fixing slots 16 are corresponding to multiple lateral crossbars 9. The outer surface of the second scaffold pole 2 is provided with a fixing ring 19. The fixing ring 19 is engaged with the inner surface of the fixing flange assembly 14. Before the fixing flange assembly 14 is locked, the fixing flange assembly 14 is rotated to align the fixing slots 16 with the lateral crossbars 9. When not locked, the fixing flange assembly 14 is engaged with the fixing ring 19 and can rotate relative to the second scaffold pole 2.

[0034] Both the outer surfaces of fastener 1401 (No. 1) and fastener 1403 (No. 3) are fixedly connected to sleeves 17. Multiple threaded rods 15 pass through the sleeves 17. Multiple threaded rod connection holes 18 are opened on the upper surface of the connecting flange 8. The ends of the threaded rods 15 are threadedly connected to the threaded rod connection holes 18. After installing the fixed flange assembly 14 and aligning the lateral crossbars 9, the threaded rods 15 are inserted into the threaded rod connection holes 18. Then, the multiple threaded rods 15 are rotated in sequence. The threaded rods 15 drive the connecting flange 8 to rise, and the connecting flange 8 drives the multiple lateral crossbars 9 to rise. The lateral crossbars 9 can then be rotated upwards. A baffle 20 is rotatably connected to the opening side of the fixing groove 16. Plate 20 is used to lock the lateral crossbar 9. After the lateral crossbar 9 is rotated into the fixing groove 16, the baffle is rotated to lock the lateral crossbar 9 into the fixing groove 16, and the No. 2 scaffold pole can be retracted. After removing the bolts of the lower connecting plate 5, the No. 2 scaffold pole can be dismantled. When installing the No. 2 scaffold pole, first connect the lower connecting plate 5 to the upper connecting plate below with bolts, and then move the baffle 20 to unfold the No. 2 scaffold pole. After connecting the crossbar of the No. 2 scaffold pole to the adjacent No. 1 scaffold pole, the fixing flange assembly 14 and the threaded rod 15 can be removed. Alternatively, they can be removed uniformly after multiple layers are installed.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
