Description

Technical Field

[0001] This invention relates to the field of lifting scaffolding technology, specifically to a modularly assembled attached lifting scaffolding and its assembly method. Background Technology

[0002] Climbing scaffolding, also known as climbing scaffolding, is a new type of external scaffolding erected to a certain height and attached to the engineering structure. It can climb or descend layer by layer with the main building by relying on its own lifting equipment and devices. It is also equipped with complete anti-overturning and anti-falling devices. The core consists of the frame structure, attachment supports, lifting and control devices, etc. It is mainly suitable for construction and decoration work of high-rise and super high-rise buildings.

[0003] Lifting scaffolds are usually combined with safety facilities such as footboards and safety nets to ensure the safety of construction workers when working at heights. The footboards are made of high-strength, non-slip materials with special surface treatment to effectively prevent workers from slipping while walking or operating. The safety nets tightly cover the outside of the scaffolds, which not only prevents people from falling accidentally, but also prevents debris and tools generated during construction from falling, protecting the safety of personnel and equipment on the ground.

[0004] However, the existing safety structures such as footboards and safety nets that accompany the lifting scaffolding are mostly fixed in an integral manner. They have a certain weight and volume. When the lifting scaffolding is working to climb the building layer by layer, these safety structures will directly become additional loads on the scaffolding, greatly increasing the overall load during the lifting process. This can easily lead to overload of the lifting power system and imbalance of the scaffolding structure, which in turn can cause safety accidents such as scaffolding overturning and falling. Therefore, in order to address the above problems, a modularly splicable attached lifting scaffolding and its assembly method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a modularly assembled attached lifting scaffold and its assembly method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A modularly assembled attached lifting scaffold and its assembly method are disclosed, comprising an attachment support, an upright assembly inserted in the attachment support, a connecting assembly installed at the bottom of the upright assembly, a guardrail assembly welded to the upper end of the connecting assembly, a footboard assembly installed on one side of the upright assembly, an upright assembly including a frame pole, an upright body welded to one side of the frame pole, a sealing plate welded to the upper end of the upright body, a pole hole opened on the inner side of the upright body, a pole seat welded to the bottom end of the upright body, a fixing installation hole opened in the pole seat, a positioning hole opened at the upper end of the pole seat, a circular hole opened on the inner side of the pole seat, a rotating column rotatably disposed in the circular hole, and a locking plate including a clamping plate, a connecting tongue plate welded to the bottom end of the clamping plate, a fixing bolt threadedly connected to the inner side of the clamping plate and the connecting tongue plate, and a long bolt rotatably disposed on the inner side of the clamping plate.

[0008] As a further optimization of the present invention, the upper surface of the sealing plate and the bottom surface of the rod seat are exactly the same in shape, the inner side of the rod seat is hollow and has an opening at the bottom, and the outer side of the card plate is in close contact with the inner side of the rod seat.

[0009] As a further optimization of the present invention, the rotating column has a T-shaped radial projection, the outer side of the rotating column is in contact with the inner side of the circular hole, the upper end face of the rotating column is flush with the upper end face of the rod seat, and the length of the rotating column is 1.5 times the length of the rod seat.

[0010] As a further optimization of the present invention, the long bolt is fixedly connected to the limiting ring, the bottom end of the limiting ring is attached to the upper end of the card plate, and the head of the long bolt is located below the card plate and is hexagonal prism in shape.

[0011] As a further optimization of the present invention, the long bolt is adapted to the positioning hole, the outer side of the fixing bolt is threaded to the inner side of the sealing plate, and the connecting tongue plate is disposed between the two upright components and is clamped by the two upright components from above and below.

[0012] As a further optimization of the present invention, the guardrail assembly includes a connecting seat, a locking bolt is threadedly connected to the inner side of the connecting seat, an ear plate is sleeved on the connecting seat, and a protective net is welded to one side of the ear plate.

[0013] As a further optimization of the present invention, the connecting seat is U-shaped, a portion of the locking bolt is disposed in the fixed mounting hole, and the ear plate has multiple square holes.

[0014] As a further optimization of the present invention, the pedal assembly includes a foot pedal, a card seat is fixedly connected to the bottom end of the foot pedal, a supporting steel pipe is welded to the bottom end of the foot pedal, two telescopic rods are provided at the bottom end of the supporting steel pipe, the telescopic rods are provided with insertion holes, a protective sleeve is provided on the outside of the telescopic rods, and a positioning bolt is installed in the insertion hole.

[0015] As a further optimization of the present invention, the card holder is F-shaped when projected along the axial direction of the positioning bolt, and a portion of the positioning bolt is inserted through the inter-rod hole opened on the inner side of the upright body, and the opening position of the insertion hole corresponds one-to-one with the opening position of the inter-rod hole.

[0016] A modular assembly method for attached lifting scaffolding:

[0017] Step 1: Adjusting the position of the upright assembly: Lift the upright assembly so that it slides in the attachment support. When the upright assembly is lifted to a certain height, stop lifting the upright assembly. The upright assembly will be stuck in the attachment support. Lift multiple upright assemblies in sequence so that the sealing plates in multiple upright assemblies are at the same height and the main bodies of multiple uprights are parallel to each other, thus completing the adjustment of the position of the upright assembly.

[0018] Step 2: Installation of connecting components: Place the connecting tongue plate on the sealing plate, then rotate the fixing bolt to fix the connecting tongue plate to the sealing plate. Then, connect the upright assembly with the connecting tongue plate fixed to it from below to the bottom end of the upright assembly that is stuck in the attachment support. First, insert the long bolt into the inside of the rod seat in the upright assembly. Use a hex wrench to turn the head of the long bolt at the gap between the upper and lower connections of the two upright assemblies so that the long bolt is screwed into the corresponding positioning hole. At the same time, the clamping plate will also be inserted into the rod seat.

[0019] Step 3: Reinforce the upright assembly and install the foot pedal: Pull the two telescopic rods and slide them in the sleeve. When the two telescopic rods are respectively attached to the upright body on both sides, use screws to fix the sleeve to the two telescopic rods. Then use the positioning bolt to pass through the insertion hole and the inter-rod hole to connect and support the upright bodies attached to both sides of the two telescopic rods. Place the support steel pipe fixed under the foot pedal on the telescopic rod and clip the card seat into the connecting seat welded to the connecting tongue plate. At the same time, put the ear plate on the connecting seat. Then turn the locking bolt so that the locking bolt passes through the card seat and the connecting seat and screws into the fixing installation hole.

[0020] Step 4: Quick disassembly of foot pedal and safety net when lifting the upright assembly: When it is necessary to lift the upright assembly, simply unscrew the locking bolt to remove the ear plate from the connecting seat, thereby removing the safety net. At the same time, after unscrewing the locking bolt, remove the foot pedal, which is fixedly connected to the card seat, from above the telescopic rod, and then lift the upright assembly.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, by setting up the upright components and connecting components, the foot pedals and protective nets are designed as modular components that can be assembled and disassembled. The modular splicing design of the foot pedals and protective nets allows the foot pedals and protective nets to be quickly disassembled during the lifting and lowering of the scaffold, avoiding the overload of the power system or the imbalance of the frame structure due to the additional load of the integral structure.

[0023] 2. In this invention, a highly flexible structural configuration and spatial adaptability are achieved. The tread assembly forms an adjustable lateral support structure, which can adapt to the main body of the uprights with different spacing, thereby flexibly meeting the erection needs of non-standard parts such as building facade taper and corners, and improving construction efficiency and versatility.

[0038] Please see Figures 1-9 The present invention provides a technical solution:

[0039] A modularly assembled attached lifting scaffold and its assembly method are disclosed. The scaffold includes an attachment support 1, a vertical support assembly 2 inserted into the attachment support 1, a connecting assembly 3 installed at the bottom of the vertical support assembly 2, a guardrail assembly 4 welded to the upper end of the connecting assembly 3, a footboard assembly 5 installed on one side of the vertical support assembly 2, a support pole 21, a vertical pole body 22 welded to one side of the support pole 21, a sealing plate 23 welded to the upper end of the vertical pole body 22, a pole-to-pole hole 24 opened inside the vertical pole body 22, a pole seat 25 welded to the bottom end of the vertical pole body 22, a fixing installation hole 26 opened in the pole seat 25, a positioning hole 27 opened at the upper end of the pole seat 25, a round hole 28 opened inside the pole seat 25, a rotating column 29 rotatably disposed in the round hole 28, and a connecting assembly 3 including a clamping plate 31, a connecting tongue plate 32 welded to the bottom end of the clamping plate 31, a fixing bolt 33 threadedly connected to the inner side of the clamping plate 31 and the connecting tongue plate 32, and a long bolt 34 rotatably disposed inside the clamping plate 31.

[0040] As a further implementation of this solution, the upper surface of the sealing plate 23 is exactly the same as the bottom surface of the pole seat 25. The inner side of the pole seat 25 is hollow and has an opening at the bottom. The outer side of the clamping plate 31 is in close contact with the inner side of the pole seat 25. The connection surfaces of the sealing plate 23 and the pole seat 25 are consistent, which allows for precise alignment and installation of the sealing plate 23 and the pole seat 25. At the same time, the tight fit between the clamping plate 31 and the pole seat 25 further enhances the assembly fit of the three components. The outer side of the clamping plate 31, which is in close contact with the inner side of the pole seat 25, acts as a reinforcing rib, forming a relatively robust structural unit.

[0041] As a further implementation of this solution, the rotating column 29 has a T-shaped radial projection. The outer side of the rotating column 29 fits against the inner side of the circular hole 28, and the upper end face of the rotating column 29 is flush with the upper end face of the rod seat 25. The length of the rotating column 29 is 1.5 times the length of the rod seat 25. The shape design of the rotating column 29 allows it to be inserted into the circular hole 28 to limit the deformation of the rod seat 25, while a part of it is inserted into the sealing plate 23 that is spliced ​​with the rod seat 25. This helps to align the sealing plate 23 and the rod seat 25 and prevents them from being misaligned due to shaking.

[0042] As a further implementation of this solution, the long bolt 34 is fixedly connected to the limiting ring 35. The bottom end of the limiting ring 35 is fitted with the upper end of the clamping plate 31. The rod head of the long bolt 34 is located below the clamping plate 31 and is hexagonal in shape. The long bolt 34 is adapted to the positioning hole 27. The outer side of the fixing bolt 33 is threaded to the inner side of the sealing plate 23. The connecting tongue plate 32 is located between the two upright components 2 and is clamped by the two upright components 2 from above and below. The fixing bolt 33 can connect the connecting tongue plate 32 to the clamping plate 23. The clamping plate 31 is fixed on the sealing plate 23. Then, through the gap between the sealing plate 23 and the clamping plate 31, the long bolt 34 can be rotated using a hex wrench so that the long bolt 34 can be screwed into the positioning hole 27. The setting of the limiting ring 35 restricts the axial displacement of the long bolt 34 so that when the long bolt 34 is screwed into the positioning hole 27, it can drive the clamping plate 31 to be locked into the rod seat 25. On the other hand, the limiting ring 35 can ensure the stability of the long bolt 34 when it rotates.

[0043] As a further implementation of this solution, the guardrail assembly 4 includes a connecting seat 41, with a locking bolt 42 threadedly connected to the inner side of the connecting seat 41. An ear plate 43 is fitted onto the connecting seat 41, and a protective net 44 is welded to one side of the ear plate 43. The connecting seat 41 is U-shaped, and part of the locking bolt 42 is located in the fixed mounting hole 26. Multiple square holes are opened in the ear plate 43. The shape of the connecting seat 41 allows other components to be inserted into it, and also allows the ear plate 43 to be fitted onto part of it, thereby achieving the hooking of the protective net 44. The locking bolt 42 serves as a component connecting the guardrail assembly 4 and the upright assembly 2. By tightening or unscrewing the locking bolt 42, the modules can be separated.

[0044] As a further implementation of this solution, the pedal assembly 5 includes a foot pedal 51, with a mounting base 52 fixedly connected to the bottom of the foot pedal 51. A support steel pipe 53 is welded to the bottom of the foot pedal 51, and two telescopic rods 54 are provided at the bottom of the support steel pipe 53. Insertion holes 55 are provided in the telescopic rods 54, and a protective sleeve 56 is fitted on the outside of the telescopic rods 54. A positioning bolt 57 is installed in the insertion hole 55. The mounting base 52 is F-shaped when projected along the axial direction of the positioning bolt 57. A part of the positioning bolt 57 is inserted through the inter-rod hole 24 opened on the inner side of the upright body 22. The positions of the insertion holes 55 and the inter-rod holes 24 are one-to-one. The shape of the mounting base 52 allows it to better support the foot pedal 51 and also facilitates its insertion into the connecting seat 41. After being fixed by the locking bolt 42, the positioning bolt 57 can fix the transverse support structure composed of the two telescopic rods 54 and the protective sleeve 56, thereby strengthening the structural strength of the upright assembly 2.

[0045] Workflow: Lift the upright assembly 2, allowing it to slide within the attachment support 1. When the upright assembly 2 reaches a certain height, stop lifting it. The upright assembly 2 will then be locked in the attachment support 1. Lift multiple upright assemblies 2 sequentially until the sealing plates 23 within each assembly are at the same height and the main upright bodies 22 are parallel to each other, thus completing the adjustment of the upright assembly 2's position. Place the connecting tongue plate 32 on the sealing plate 23, and then rotate the fixing bolt 33. Fix the connecting tongue plate 32 to the sealing plate 23, and then connect the upright assembly 2 with the connecting tongue plate 32 fixed to it from below to the bottom end of the upright assembly 2 that is stuck in the attachment support 1. First, insert the long bolt 34 into the inside of the rod seat 25 in the upright assembly 2. Use a hex wrench to turn the head of the long bolt 34 at the gap between the upper and lower connections of the two upright assemblies 2, so that the long bolt 34 is screwed into the corresponding positioning hole 27. At the same time, the locking plate 31 will also be locked into the rod seat 25. Pull the two telescopic rods 54 in the sheath 56. When the two telescopic rods 54 are respectively attached to a vertical pole body 22 on both sides, use screws to fix the sheath 56 to the two telescopic rods 54. Then, use the positioning bolt 57 to pass through the insertion hole 55 and the pole hole 24 to connect and support the vertical pole bodies 22 attached to both sides of the two telescopic rods 54. Place the support steel pipe 53 fixed under the foot pedal 51 on the telescopic rod 54, and snap the card seat 52 into the connecting seat 41 welded to the connecting tongue plate 32. At the same time, also attach the ear plate 43. The locking bolt 42 is then screwed onto the connecting seat 41 and then through the card seat 52 and the connecting seat 41 and into the fixing mounting hole 26. When it is necessary to lift the upright assembly 2, simply unscrew the locking bolt 42 to remove the ear plate 43 from the connecting seat 41, thereby removing the protective net 44. At the same time, after unscrewing the locking bolt 42, the foot pedal 51, which is fixedly connected to the card seat 52, is removed from above the telescopic rod 54. Then the upright assembly 2 can be lifted.
