Description

Technical Field

[0001] A modular scaffolding tie-up device for ultra-high-rise buildings belongs to the field of building scaffolding technology. Background Technology

[0002] In construction projects, scaffolding serves as a primary reusable material, and its selection significantly impacts the overall construction process. In irregularly shaped projects or high-rise construction, the most crucial aspect of scaffolding erection and safety is the installation of wall ties. For high-rise buildings, especially frame structures, the floor height and span are typically large, resulting in significant scaffold cantilever heights, and the lack of wall ties makes installation difficult. Current technologies primarily employ the following methods for connecting ties:

[0003] (1) Using steel cable connections, such as the technical solution described in the Chinese utility model patent with application number 202222197370.1, application date August 20, 2022, entitled "A Cantilever Scaffold", and the technical solution described in the Chinese invention patent with application number 202110415401.3, application date April 18, 2021, entitled "Tool-type Temporary Cantilever Steel Beam Foundation System Device and Installation and Dismantling Method". The drawback of steel cable connections is that the closed loop at the connection point is prone to loosening.

[0004] (2) Using plate connections, such as the technical solutions recorded in the Chinese utility model patent with application number 202121407342.7, application date June 24, 2021, and patent name "A Flower Basket Tie Rod Type Suspended Scaffold Support", and the technical solutions recorded in the Chinese invention patent with application number 202220239538.8, application date January 28, 2022, and patent name "A Connecting Tie Rod for Cantilever Beams".

[0005] (3) Bolted connection, such as the technical solution recorded in the Chinese invention patent with application number 202110799086.9, application date July 15, 2021, and patent name "An adjustable cantilever beam assembly and its construction method".

[0006] The drawbacks of plate connections and bolted connections are that the allowance for movement at the connection point is small, which makes them prone to damage after long-term use and poses certain safety hazards.

[0007] (4) Fastener connection, such as the technical solution described in Chinese invention patent application number 202410999519.9, application date July 24, 2024, entitled "A method for erecting scaffolding". The defects of fastener connection are: the included angle is easy to exceed the specification requirements, the pull-out bearing capacity is insufficient, and the swivel fastener is prone to slippage and loosening under dynamic load.

[0008] (5) Hook and loop connection, such as the technical solution described in Chinese invention patent application number 202210678075.X, application date June 15, 2022, entitled "Demountable diagonal tie rod pre-embedded assembly and its installation method". Although hook and loop connection can provide a large amount of flexibility and is not easy to loosen, it is difficult to connect with pipes in scaffolding and has low applicability. Utility Model Content

[0009] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a structure that utilizes the sliding connection of the movable plate and the fixed plate in the hanging mechanism to form a closed loop after closure, thereby improving safety, providing a certain amount of mobility, and facilitating the connection of various hanging parts, including pipe fittings. This makes it a highly applicable combination scaffolding tie device for ultra-high floors.

[0010] The technical solution adopted by this utility model to solve its technical problem is as follows: the super high-rise building combined scaffolding tie device includes a base, a hanging rod is rotatably installed on the surface of the base, and a hanging mechanism is provided at the end of the hanging rod. The hanging mechanism includes a movable plate and a fixed plate fixed to the hanging rod. One side of the movable plate and the fixed plate forms an overlapping part and is slidably connected. The other side of the movable plate and the fixed plate forms a locking end opposite to each other. The locking ends of the movable plate and the fixed plate are connected to form a closed loop.

[0011] Preferably, both the movable plate and the fixed plate are arc-shaped plates, and a groove is cut on one side of the movable plate to form a set of opposing movable inserts, and the fixed plate is inserted between the movable inserts on both sides to form an overlapping part.

[0012] Preferably, at the overlapping part of the movable plate and the fixed plate, a groove is formed on the surface of the movable plate, and a limiting rod placed in the groove is provided on the surface of the fixed plate.

[0013] Preferably, the limiting rod is a stop provided on the surface of the fixed plate or a bolt passing through the fixed plate and the slide groove.

[0014] Preferably, the locking ends of the movable plate and the fixed plate are staggered or plugged together.

[0015] Preferably, a movable plate connection hole and a fixed plate connection hole are respectively provided at the locking ends of the movable plate and the fixed plate, and the movable plate connection hole and the fixed plate connection hole coincide when the locking ends are mated.

[0016] Preferably, the hanging rod includes a connecting rod and a swing rod, one end of the connecting rod and one end of the swing rod are fixedly connected, the hanging mechanism is fixed to the other end of the connecting rod, and the other end of the swing rod is rotatably connected to the base.

[0017] Preferably, the base includes a substrate, a substrate fixing plate is vertically fixed on the surface of the substrate, a swing plate is fixed at the bottom of the swing rod, and the swing plate is connected to the substrate fixing plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] In the high-rise building combined scaffolding tie device described in this application, the structure of sliding connection between the movable plate and the fixed plate in the hooking mechanism can form a closed loop after closure, which improves safety, provides a certain amount of mobility, and facilitates the connection of various hooking components, including pipe fittings, thus having high applicability.

[0020] In this application, a movable fixed base and connecting rods are used to tie and fix the external scaffolding, eliminating the waiting time for pouring concrete as with traditional pre-embedded steel pipes. It does not rely on the concrete curing period and allows for flexible interleaving of construction work according to the scaffolding erection progress.

[0021] In this application, steel pipes and hanging mechanisms are used to quickly connect and fix the scaffolding horizontal members. This double-fixation ensures stable stress distribution. It eliminates the risk of loosening associated with traditional wall ties and guarantees the stability of the free end of the scaffolding under wind and construction loads.

[0036] Figures 1-9 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-13 The present invention will be further described below.

[0037] Example 1:

[0038] like Figure 1 As shown, a high-rise modular scaffolding tying device includes a base, a swing rod 4 rotatably connected to the surface of the base, a connecting rod 2 connected to the upper end of the swing rod 4 by multiple clamps 3, and a hanging mechanism 1 provided at the end of the connecting rod 2. The base is fixed to a fixed surface (such as the ground), and then the connecting rod 2 extends to the connecting pipe 22 of the scaffolding (see...). Figure 9 The scaffold is fixed at the location and connected to the connecting pipe 22 through the hanging mechanism 1. Then, the connecting rod 2 and the swing rod 4 are fixed by the clamp 3, thereby realizing the fixation of the scaffold.

[0039] Such as combination Figure 2 The base includes a substrate 9, with fixing holes at the four corners of the substrate 9. An expansion bolt 7 is placed in each fixing hole to fix the substrate 9 to the fixing surface. A substrate fixing plate 8 is vertically fixed to the surface of the substrate 9, and a swing plate 5 is axially fixed to the bottom of the swing rod 4. After the swing plate 5 and the substrate fixing plate 8 are attached, a connecting bolt 6 passes through both the swing plate 5 and the substrate fixing plate 8, and the swing plate 5 and the substrate fixing plate 8 are rotated together by a connecting nut 10 and a washer.

[0040] like Figure 3 As shown, a hanging plate 13 is axially fixed to the end of the connecting rod 2, and a hanging mechanism 1 is fixed to the top of the hanging plate 13. The hanging mechanism 1 includes a movable plate 12 and a fixed plate 14. The movable plate 12 and the fixed plate 14 are preferably arc-shaped plates with the same radius, and the angles corresponding to the arc lengths of the movable plate 12 and the fixed plate 14 are both greater than 180°.

[0041] One end of the fixed plate 14 is fixed to the top of the hanging plate 13. The movable plate 12 is snapped into the fixed plate 14 and slides back and forth along its circumference. Fixed plate connection hole 15 and movable plate connection hole 11 are respectively opened at the opposite ends of the fixed plate 14 and the movable plate 12. When the opposite ends of the fixed plate 14 and the movable plate 12 are connected, a closed loop is formed, and the fixed plate connection hole 15 and the movable plate connection hole 11 are axially coincident. At this time, a bolt (or pin) is passed through the coincident hole of the fixed plate connection hole 15 and the movable plate connection hole 11 to lock the closed loop structure formed by the fixed plate 14 and the movable plate 12.

[0042] like Figures 4-6 As shown, the fixing plate 14 includes an arc-shaped fixing plate body 17. A locking plate 16 is formed by slotting at one end of the fixing plate body 17 opposite to the movable plate 12. The fixing plate connecting hole 15 is axially opened at the end of the locking plate 16.

[0043] Combination Figures 7-8 The movable plate 12 includes an arc-shaped movable plate body 19. An arc-shaped groove is radially formed in the middle of one end of the movable plate body 19. Movable insert plates 20 are formed on both sides of the arc-shaped groove. The axial width of the insertion hole between the two movable insert plates 20 is greater than the thickness of the fixed plate 14. The movable plate 12 is snapped onto the outside of the fixed plate 14 through the insertion hole at its end.

[0044] Arc-shaped grooves 21 are axially formed in the movable inserts 20 on both sides of the movable plate 19. A stop 18 is provided on each of the two end faces of the fixed plate 17. The stop 18 on both sides passes through the grooves 21 on the corresponding sides to complete the snap-fit ​​connection between the movable plate 12 and the fixed plate 14. The stop 18 and the grooves 21 enable the movable plate 12 and the fixed plate 14 to slide back and forth while the movable plate 12 also has a certain rotation angle.

[0045] A notch is provided at one end of the movable plate 19 opposite to the fixed plate 14 to accommodate the locking plate 16. When the fixed plate 14 and the movable plate 12 are connected to form a closed loop, the locking plate 16 is staggered with the end of the movable plate 19 to form a closed loop, thereby achieving the overlap of the fixed plate connection hole 15 and the movable plate connection hole 11.

[0046] The specific operation process is as follows:

[0047] A hole is made on the fixed surface, and the substrate 9 is placed in the hole. Then, the substrate 9 is fixed on the fixed surface by the expansion bolt 7, and the substrate 9 is connected and fixed to the swing rod 4 by the connecting bolt 6 and the connecting nut 10.

[0048] Rotating the movable plate 12 in the hanging mechanism 1, using the stop 18 and the slide 21, allows the movable plate 12 to partially overlap with the fixed plate 14, leaving an opening. Then, the connecting pipe 22 in the scaffold is placed inside the hanging mechanism 1. Next, the movable plate 12 is rotated in the opposite direction, causing its end to align with the locking plate 16 at the end of the fixed plate 14, forming a closed loop. At this point, the ends of the movable plate 12 and the fixed plate 14 are staggered, and the connecting holes 15 and 11 of the fixed plate and movable plate overlap. Bolts (or pins) pass through the overlapping holes of the fixed plate connecting holes 15 and the movable plate connecting holes 11, locking the connecting pipe 22 within the hanging mechanism 1. Figure 9 The state shown.

[0049] Finally, the connection between the connecting rod 2 and the swing rod 4 is fixed by the clamp 3, thereby achieving the fixation of the scaffold.

[0050] Example 2:

[0051] The difference between this embodiment and embodiment 1 is that the structures of the movable plate 12 and the fixed plate 14 in the hanging mechanism 1 are different.

[0052] like Figures 10-11 As shown, in this embodiment, slots are cut on both sides of the fixed plate 14 at one end relative to the movable plate 12, so that the locking plate 16 is located in the middle of the fixed plate 14. Figures 12-13 As shown, for the movable plate 12, a movable plate slot 23 is opened in the middle of the end that mates with the locking plate 16. When the fixed plate 14 and the movable plate 12 mate to form a closed loop, the locking plate 16 is inserted into the movable plate slot 23 to achieve the mate.

[0053] Example 3:

[0054] The difference between this embodiment and embodiment 1 is that the structure of the fixing plate 14 in the hanging mechanism 1 is different. In this embodiment, the baffle 18 is omitted, and a through hole is opened in the fixing plate body 17 corresponding to the position of the baffle 18. After the movable plate 12 is engaged with the fixing plate 14 through the movable insert plate 20 at its end, the bolt passes through the through hole and the slide groove 21 on the surface of the fixing plate body 17, replacing the baffle 18.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
