Description

Technical Field

[0001] The present invention belongs to the field of scaffolding, and particularly relates to a modular general lifting scaffolding. Background Art

[0002] The lifting scaffolding is abbreviated as climbing frame or lifting frame, which can rise or fall along the outer facade of a building. It is mainly used for the peripheral protection during the construction of the main structure of high-rise buildings and is one of the most common construction equipment in recent years. However, there are the following pain points in the current entire climbing frame industry:

[0003] 1. Isolated system and single application scenario

[0004] The existing mainstream climbing frame products on the market are called all-steel climbing frames; the frame structure is mainly composed of square tube vertical poles and square tube walkway plates. Such a structural form and technical path have major defects, that is, the system is isolated and the application scenario is single. It can only be used for the peripheral protection during high-rise building construction, and there is no second application scenario other than this. It has no connection with the existing steel pipe racks and disk buckle racks of the same external frame system and cannot be compatible. Therefore, it does not have the characteristics of high flexibility and strong adaptability of the above two systems. With the current downturn in the construction industry, the construction volume of high-rise buildings continues to decline, the supply in the climbing frame market exceeds the demand, and the market inventory is far in excess. Climbing frame operators have no room for transformation and can only treat the climbing frames as scrap iron.

[0005] 2. Lack of generalization and standardization, resulting in huge waste of resources

[0006] At present, there are many climbing frame manufacturers in China. However, due to the lack of unified and standardized design and production standards, the main components of climbing frames have not formed modularization, generalization, serialization, and standardization. The structural components of each brand model of climbing frames are not universal and interchangeable, which is not conducive to resource integration and effective utilization, resulting in the devaluation of second-hand climbing frames; especially many current climbing frame operators who are struggling can only treat the good climbing frames as scrap iron, causing huge waste of resources.

[0007] 3. Unreasonable structural design and high operation cost

[0008] All connections between the frame structural components are bolt connections. During the frequent disassembly and assembly process, the work efficiency is low and the loss is large; the structural component design has not formed modularization and standardization, resulting in many non-standard parts and large losses, and the operation cost is very high.

[0009] A kind of aluminum alloy - steel combined attached lifting scaffold is disclosed in the patent document with the application number "CN2022203909745", which includes a main frame, vertical poles, footboards, and a lifting system. The vertical poles include outer vertical poles and inner vertical poles. At the bottommost part between every two adjacent outer vertical poles and inner vertical poles, there is a bottom cross bar. Above the bottom cross bar, several triangular braces are evenly arranged. Above the bottom cross bar and the triangular braces at the same height, footboards are both provided. Between adjacent outer vertical poles and adjacent inner vertical poles, there are truss diagonal web members and safety nets. The lifting system includes a lifting hanging seat, an electric hoist head, a lifting chain, an upper hanging point truss, and a lower hanging point truss. On the lifting chain, there is a hoist connecting piece that can be adjusted to move up and down. The two ends of the lifting hanging seat are respectively connected and fixed to the hoist connecting piece and the building structure beam. The lifting scaffold disclosed in this comparative document is similar in structure to the existing scaffolds on the market, both being integral assembled structures. The span of its frame body, the shape and size of the cross-section of parts such as vertical poles, cross bars, and diagonal web members, as well as the length of the rod body are all non-standard values, and the connection parts cannot be universal. It still has the disadvantages of poor versatility and compatibility, low building flexibility, and high cost.

[0010] The disclosure of the above background technical content is only used to assist in understanding the inventive concept and technical solution of the present invention. It does not necessarily belong to the prior art of this patent application. Without clear evidence indicating that the above content was publicly available on the filing date of this patent application, the above background technology should not be used to evaluate the novelty and inventiveness of this application.

[0022] Compared with the existing technology, the present invention has the following beneficial effects:

[0023] 1. The modular general-purpose lifting scaffold in the present invention is composed of a main load-bearing frame and an intermediate scaffold installed with each other to form a frame body. The guide rail and the lifting power unit are connected to the main load-bearing frame to drive the lifting of the main load-bearing frame. The vertical main frame is provided with socket couplings, which can not only be connected to the socket-coupled intermediate scaffold, so as to achieve the function of being compatible with the socket-coupled scaffold system, but also the production standards of each main load-bearing frame and each part are consistent with the socket-coupled national standard. Therefore, it can be flexibly modularly built and mutually universal according to the actual situation, improving the installation convenience and reducing the operation and use costs.

[0024] 2. The main load-bearing frame in the present invention is composed of a horizontal load-bearing truss and a vertical main frame. The horizontal load-bearing truss can simulate the ground and support the weight of the upper intermediate scaffold and construction loads; the vertical main frame can not only fix the intermediate scaffold, but also play multiple roles such as assembling with the guide rail, preventing the frame body from overturning, and connecting with other main load-bearing frames during modular assembly.

[0025] 3. The first frame body and the second frame body in the present invention can not only ensure the strength of the vertical main frame and the horizontal load-bearing truss, but also the first diagonal rod and the second diagonal rod are respectively close to the first cross bar and the second cross bar in their respective areas and have opposite inclination directions, so as to form a horizontal passage, allowing personnel to pass between the modular frame bodies while ensuring the strength.

[0026] 4. Plane connecting trusses are connected between the second frame bodies in the horizontal load-bearing truss of the present invention. The top of the plane connecting truss is provided with a double cross brace reinforcement structure, and the lower connecting ends of the diagonal braces are dispersed into a structure radiating upward near the upper connecting ends, which can increase the ability of the horizontal load-bearing truss to bear the top load to ensure the connection safety of the intermediate scaffold. And the second frame body is set in multiples of the scaffold cross bar modulus, and the scaffold cross bar modulus value is 30 cm, so that it can be compatible and universal with the conventional scaffold.

[0027] 5. In the present invention, the secondary plate fixing member in the flap assembly is connected to the frame structure in a hanging manner. It can be quickly installed not only on the horizontal connecting rod of the intermediate scaffolding but also on the second cross bar of the horizontal load-bearing truss. It is limited and prevented from falling off by a limit bolt. The walkway board is installed in the frame structure in a scaffolding manner, and the ends are overlapped with each other on the transverse structural rod and then fixed by a U-shaped pipe clamp, enabling the flap assembly and the walkway board to be compatibly installed and used between the intermediate scaffolding and the main load-bearing frame, facilitating modular management. 6. After integrating and compatibly using the disk lock scaffolding, the present invention has the following outstanding advantages:

[0028] Heavy assets become light assets: The operator of the climbing frame only needs to invest a small amount of funds to purchase the horizontal support truss, vertical main frame and related accessories. The relatively large part of the disk lock frame can be rented from the disk lock supplier, maximizing the integration of social resources and realizing the transformation from the original heavy asset operation to a light asset operation;

[0029] Beneficial to resource integration: After having universality and interchangeability, resources among peers can be shared, and the resources of the whole society can also be integrated, which can reduce costs and increase revenues. At the same time, it will also make the second-hand climbing frame more valuable; achieving multiple benefits and a win-win situation;

[0030] Improve efficiency and reduce costs: The new climbing frame of the present invention, by integrating the design system of the disk lock and the design system of the scaffolding, has modularity, standardization and generalization, which improves the erection efficiency, reduces the labor cost and has less loss, with very significant economic benefits.

[0051] As Figures 1 to 7As shown in the figure, the modular universal lifting scaffold in this embodiment includes: a frame body, a wall-attached support 100, and a lifting support 110. The wall-attached support 100 and the lifting support 110 are fixedly installed on the building structure. The frame body is composed of a main load-bearing frame 200 and an intermediate scaffold 300. The main load-bearing frame 200 is further composed of a horizontal load-bearing truss 400 and two vertical main frames 500. The two vertical main frames 500 are vertically arranged and have a certain distance between them. The lower end of the vertical main frame 500 is fixedly connected to the horizontal load-bearing truss 400 in a detachable manner through a first connecting member 210. The upper end of the vertical main frame 500 extends above the horizontal load-bearing truss 400. A plurality of disk buttons 230 are arranged at intervals along the vertical main frame 500. Two frame bodies can be connected through the disk buttons 230 and the corresponding disk button type connecting rods with lock heads 350. The intermediate scaffold 300 is a disk button type scaffold. The side part of the intermediate scaffold 300 is fixedly connected to the disk buttons 230 in a detachable manner. The lower end of the intermediate scaffold 300 is fixedly connected to the horizontal load-bearing truss 400 in a detachable manner through a second connecting member 220. The guide rail 120 and the lifting power unit 130 are fixedly connected to the main load-bearing frame 200 in a detachable manner. The lifting power unit 130 includes: an upper lifting frame 131, a lower lifting frame 132, and a climbing frame electric hoist 133. The upper lifting frame 131 is fixedly connected to the vertical main frame 500. The lower lifting frame 132 is fixedly connected to the horizontal load-bearing truss 400. The upper hook and the lower hook of the climbing frame electric hoist 133 are respectively fixedly connected to the upper lifting frame 131 and the lower lifting frame 132. The chain of the climbing frame electric hoist 133 is fixedly connected to the lifting support 110. When the chain of the climbing frame electric hoist 133 runs, it can drive the frame body to move up and down with the lifting support 110 as the fulcrum. The wall-attached support 100 is connected to the guide rail 120 in a slidable manner. A limited-slip top support is arranged between the wall-attached support 100 and the guide rail 120. One end of the limited-slip top support is rotatably connected to the wall-attached support 100, and the other end can support on the cross-connecting part between the guide rails 120, so as to prevent the frame body from falling down. A detachable steel plate punching net 140 is installed on the outer side of the frame body, and a flap assembly 700 is provided on the inner side of the frame body.

[0052] More specifically, the vertical main frame 500 includes a number of first frame bodies 510. The first frame body 510 includes a first vertical rod 511 and a first horizontal rod 512. The number of the first vertical rods 511 is two and they are arranged in parallel. The first connecting members 210 are arranged at both ends of the first vertical rod 511 and can be fixedly connected to each other in a detachable manner. A plurality of socket fasteners 230 are arranged along the first vertical rod 511. Both ends of the first horizontal rod 512 and both ends of the first diagonal rod 513 are welded to the side of one first vertical rod 511. One or two first diagonal rods 513 are arranged between every two first horizontal rods 512. The installation positions of the first diagonal rods 513 are close to the upper and lower sides of the first horizontal rod 512 and the inclination directions of two adjacent first diagonal rods 513 are opposite, so as to form a passage for people to pass through between the two first diagonal rods 513.

[0053] More specifically, the horizontal load-bearing truss 400 includes a plurality of second frame bodies 410. Each second frame body 410 is arranged at intervals that are multiples of the modular size of the scaffolding cross bar in the horizontal direction and are parallel to each other. A detachable planar connecting truss 420 is connected between each second frame body 410. Here, the modular size of the scaffolding cross bar is 30 cm; the second frame body 410 includes a second vertical rod 411, a second horizontal rod 412 and a second diagonal rod 413. The number of the second vertical rods 411 is two and they are arranged in parallel. The upper end of the second vertical rod 411 is provided with a first connecting member 210 or a second connecting member 220. The first connecting member 210 is used for connecting with the lower end of the first frame body 510. The number of the second horizontal rods 412 is two and both ends are fixedly connected to one second vertical rod 411 respectively. Two second diagonal rods 413 are arranged between the two second horizontal rods 412. Both ends of the second diagonal rod 413 are fixedly connected to the second vertical rod 411 respectively. The two second diagonal rods 413 are respectively close to the second horizontal rod 412 and the inclination directions are opposite, so as to form a passage for people to pass through between the two second diagonal rods 413; first ear plates 414 are respectively arranged near the upper end and the lower end of the second vertical rod 411; two cross braces 421 are arranged at the top of the planar connecting truss 420. The two cross braces 421 are parallel to each other and are connected to each other through a connecting plate 422. One cross brace 421 is arranged at the bottom of the planar connecting truss 420. Second ear plates 423 are respectively welded at both ends of the cross brace 421. The positions of the second ear plates 423 correspond to those of the first ear plates 414 and are connected by bolts. Two or more nail holes are formed in both the second ear plates 423 and the first ear plates 414. A number of diagonal braces 424 are arranged in the middle of the planar connecting truss 420. Both ends of the diagonal brace 424 are respectively welded to one cross brace 421. When the width of the planar connecting truss 420 is greater than one time of the modular size of the scaffolding cross bar, more than three diagonal braces 424 are arranged in the planar connecting truss 420. The lower ends of the diagonal braces 424 are close to each other and the upper ends of the diagonal braces 424 are far from each other, forming an inverted triangle support structure.

[0054] It should be noted that the preferred structure of the first connecting member 210 above is a flange connecting plate, and the preferred structure of the second connecting member 220 is a connecting sleeve. In addition, the first connecting member 210 can also adopt structural forms such as a connecting sleeve, a connecting buckle plate, or a screw sleeve connection, and the second connecting member 220 can also adopt structural forms such as a flange connecting plate, a connecting buckle plate, or a screw sleeve connection.

[0055] More specifically, the intermediate scaffolding 300 includes vertical connecting rods 310, horizontal connecting rods 320, and inclined connecting rods 330. Both ends of the vertical connecting rods 310 are connected by a first sleeve 340, and a plurality of disc fasteners 230 are provided on the vertical connecting rods 310. Both ends of the horizontal connecting rods and both ends of the inclined connecting rods 330 are respectively fixedly connected to the disc fasteners 230 through locking heads 350. The lower end of the vertical connecting rod 310 at the bottom of the intermediate scaffolding 300 is connected to the top end of the second vertical rod 411 through the second connecting member 220. It should be noted that the connection structure between the disc fastener 230 and the locking head 350 is an existing standardized structure and is common knowledge to those skilled in the art, so it will not be elaborated here.

[0056] More specifically, the horizontal connecting rods 320 are at the same height as the first crossbars 512, and the horizontal connecting rods 320 are at the same height as the second crossbars 412. Walkway boards 600 are respectively laid between each horizontal connecting rod 320 and the first crossbars 512 and between the horizontal connecting rods 320 and the second crossbars 412. Through holes are provided at the ends of each walkway board 600, and the edges are overlapped with each other at the horizontal connecting rods 320, the first crossbars 512, and the second crossbars 412 and fixed by U-shaped pipe clamps; the flap assembly 700 includes a sub-board fixing member 710, a sub-board 720, and a flap 730. The sub-board fixing member 710 is a long rod-shaped structure. Two first hooks 711 are welded on the sub-board fixing member 710, and a limit bolt 712 is installed. The position of the limit bolt 712 corresponds to the mouth of the first hook 711. The first hook 711 can be hung from below on two horizontal connecting rods 320 or two second crossbars 412 and limited by the limit bolt 712 to prevent unhooking. One end of the sub-board fixing member 710 extends outward from the inner side of the frame body and is fixedly connected to one side of the sub-board 720. One side of the flap 730 is hinged to one side of the sub-board 720 through a hinge buckle 740, and the other side of the flap 730 can be flipped towards the walkway board 600.

[0057] In addition, a suspension rod 800 is also installed on the horizontal load-bearing truss 400. Two second hooks 810 are arranged on the side of the suspension rod 800, and the second hooks 810 hook the cross brace 421 from below; the guide rail 120 is provided with a fixed rod 121, and the fixed rod 121 is fixedly connected to the first vertical rod 511 and the second vertical rod 411 at the same time. One side of the upper lifting frame 131 is fixedly connected to the fixed rod 121, and both sides of the lower lifting frame 132 are fixedly connected to the suspension rod 800 and the fixed rod 121 respectively. The upper hook and the lower hook of the climbing frame electric hoist 133 are fixedly connected to the upper lifting frame 131 and the lower lifting frame 132 respectively. The suspension rod 800 can increase the fixing strength of the lower lifting frame 132. The chain of the climbing frame electric hoist 133 is fixedly connected to the lifting support 110. The climbing frame electric hoist 133 is a general component on the existing climbing frame, and its structure and principle are common knowledge in the art, so details are not described here.

[0058] In summary, in this embodiment, the modular general-purpose lifting scaffold is designed with a split structure in which the frame body is composed of the main load-bearing frame 200 and the intermediate scaffold 300. The guide rail 120 and the lifting power unit 130 are connected to the main load-bearing frame 200 to drive the main load-bearing frame 200 to lift and lower. The vertical main frame 500 of the external lifting frame is provided with socket discs 230, which can not only be connected to the socket disc 230 type intermediate scaffold 300, but also enable the connection between the external lifting frames. Moreover, the socket disc 230 structure also allows a certain angle between the external lifting frames, so that modular flexible construction can be carried out according to the actual working environment conditions, and it can also be compatible and universal with the socket disc 230 scaffolds on the market. When purchasing, the intermediate scaffold 300 can be replaced by the existing ordinary scaffold. When idle, the main load-bearing frame 200 can also be used as an ordinary scaffold, reducing the costs in the procurement and storage processes, improving the usage frequency of the equipment, and further reducing the usage cost.
