Technical Field

[0001] This application relates to the field of cantilever scaffolding technology, specifically to a leveling device and cantilever scaffolding. Background Technology

[0002] Cantilever scaffolding refers to external scaffolding used in construction where the vertical load is transferred to the structural entity through a bottom steel support frame.

[0003] Currently, the support frame of cantilever scaffolding is fixed to I-beams by pre-embedding bolts in the structural body. However, deviations can occur during bolt pre-embedding and I-beam installation, resulting in uneven support frame elevations or uneven support surfaces, thus affecting the stability of the scaffolding. Therefore, after the support frame of cantilever scaffolding is installed, the support surface of the support frame needs to be leveled.

[0004] The existing leveling method involves placing shims or wooden boards on the support surface of the support frame for leveling. However, this leveling method is cumbersome, inefficient, and has poor leveling effect, which affects the erection efficiency of cantilever scaffolding. Summary of the Invention

[0006] The technical solution adopted by this application to solve its technical problem is: a leveling device, including two support seats arranged at intervals along a first direction, a crossbeam support plate provided between the two support seats, and the two support seats respectively connected to both ends of the crossbeam support plate through a height adjustment component, the height adjustment component being used to adjust the height of the crossbeam support plate.

[0007] Furthermore, the support base includes a lower support plate disposed below the crossbeam support plate, an upper support plate disposed above the crossbeam support plate, and a side connecting plate connecting the lower support plate and the upper support plate; the height adjustment component is connected between the upper support plate and the crossbeam support plate.

[0008] Furthermore, the height adjustment assembly includes a height adjustment bolt passing through the upper support plate from top to bottom, a fixing nut threaded onto the height adjustment bolt, the fixing nut being connected to the crossbeam support plate, and an clearance hole provided on the crossbeam support plate opposite to the fixing nut for the end of the height adjustment bolt to pass through.

[0009] Furthermore, the height adjustment assembly contains two height adjustment bolts, which are arranged at intervals along a second direction, and the second direction intersects with the first direction.

[0010] Furthermore, two downwardly extending limiting side plates are connected to the crossbeam support plate, and a limiting groove extending in a first direction is formed between the crossbeam support plate and the two limiting side plates.

[0014] Furthermore, the fastening structure includes a U-bolt passing through the crossbeam pressure plate from bottom to top, a fastening nut connected to the end of the U-bolt, and two limiting side plates located inside the U-bolt.

[0029] See Figure 1 , Figure 2 , Figure 3The leveling device 3 provided in this application includes two support seats 31 arranged at intervals along a first direction. A crossbeam support plate 32 is provided between the two support seats 31. The two support seats 31 are respectively connected to the two ends of the crossbeam support plate 32 through a height adjustment component 33. The height adjustment component 33 is used to adjust the height of the crossbeam support plate 32.

[0030] The embodiment of this application provides a leveling device 3, which is used to quickly level the support surface of the support frame of the cantilever scaffolding instead of shims or wooden boards, so as to ensure the stability of the cantilever scaffolding and improve the erection efficiency of the cantilever scaffolding.

[0031] See Figure 4 The support frame of the cantilever scaffold mainly consists of multiple spaced main beams 1. The upper surface of the main beam 1 serves as the support surface of the support frame. One end of the main beam 1 is fixedly connected to the structural entity 4 via pre-embedded bolts. To improve the stability of the main beam 1 after installation, it is also connected to the structural entity 4 via diagonal tie rods 5. The main beam 1 can be made of I-beams, H-beams, etc. For simplicity, Figure 4 The diagram only shows the structure of two main beams 1; it can be understood that there can be more than two main beams 1. After the main beams 1 of the cantilever scaffold are installed, one or more leveling devices 3 can be installed on the main beams 1 to level the support surface of the support frame, depending on the actual situation.

[0032] The installation and leveling process of the leveling device 3 is as follows: The two support seats 31 of the leveling device 3 are supported on the main beam 1 and connected to the main beam 1 by welding or bolting. At this time, the support surface of the support frame is equivalent to the upper surface of the crossbeam support plate 32 from the upper surface of the main beam 1. The upper surface of the crossbeam support plate 32 is used to support other structures such as the crossbeam 2. Then, the height adjustment component 33 is controlled to adjust the height of the crossbeam support plate 32. With the cooperation of the two sets of height adjustment components 33, the crossbeam support plate 32 is quickly leveled. When the upper surfaces of all crossbeam support plates 32 are leveled and the elevation is consistent, the leveling work of the support surface of the cantilever scaffold is completed.

[0033] See Figure 3 The support base 31 includes a lower support plate 311 disposed below the crossbeam support plate 32, an upper support plate 312 disposed above the crossbeam support plate 32, and a side connecting plate 313 connecting the lower support plate 311 and the upper support plate 312; the height adjustment component 33 is connected between the upper support plate 312 and the crossbeam support plate 32.

[0034] For example, both the lower support plate 311 and the upper support plate 312 are horizontally arranged rectangular or square plates; the lower support plate 311 is used to support the main beam 1 during installation, and the upper support plate 312 is disposed above the lower support plate 311, forming an adjustment space between them for adjusting the height of the crossbeam support plate 32. The height adjustment component 33 is connected between the upper support plate 312 and the crossbeam support plate 32, and is used to adjust the height of the crossbeam support plate 32 within the adjustment space.

[0035] See also Figure 3 The height adjustment assembly 33 includes a height adjustment bolt 331 passing through the upper support plate 312 from top to bottom, a fixing nut 332 threaded onto the height adjustment bolt 331, and the fixing nut 332 connected to the crossbeam support plate 32. The crossbeam support plate 32 has a clearance hole on its surface opposite the fixing nut 332, allowing the end of the height adjustment bolt 331 to pass through. For example, the height adjustment assembly 33 contains two height adjustment bolts 331, which are spaced apart along a second direction, intersecting with the first direction. The first and second directions can be horizontally aligned, for example, the first direction can be perpendicular to the second direction.

[0036] The upper support plate 312 has bolt holes for the height adjustment bolt 331 to pass through. When the shank of the height adjustment bolt 331 passes through the bolt holes, its head rests on the upper support plate 312. The fixing nut 332 can be welded to the crossbeam support plate 32. The fixing nut 332 can be positioned above or below the crossbeam support plate 32. During operation, simply rotating the height adjustment bolt 331 will move the crossbeam support plate 32 up and down via the fixing nut 332, thus adjusting the height of the crossbeam support plate 32.

[0037] See Figure 1 , Figure 2 , Figure 3 Two downwardly extending limiting side plates 34 are connected to the crossbeam support plate 32, and a limiting groove 35 extending in the first direction is formed between the crossbeam support plate 32 and the two limiting side plates 34. When the support base 31 is supported on the main beam 1, the main beam 1 can be located in the limiting groove 35, and the two limiting side plates 34 are used to limit the two sides of the main beam 1, avoiding the possibility of the leveling device 3 overturning on the main beam 1, and ensuring the reliability of the leveling device 3 after it is installed on the main beam 1.

[0038] Furthermore, the limiting side plate 34 has a locking bolt 36 that passes through it, and the locking bolt 36 is threadedly connected to the limiting side plate 34. For example, each limiting side plate 34 is provided with two locking bolts 36. By providing locking bolts 36, after the leveling device 3 is installed to the main beam 1, only the locking bolts 36 need to be tightened. When the locking bolts 36 abut against the main beam 1, the leveling device 3 is firmly connected to the main beam 1, without the need to weld the support base to the main beam 1, which facilitates the subsequent disassembly, assembly, and reuse of the leveling device 3.

[0039] To improve the stability of the two limiting side plates 34 and prevent deformation of the two limiting side plates 34, a base plate 37 is connected between the lower ends of the two limiting side plates 34.

[0040] After the leveling device 3 is installed on the main beam 1 and leveled, the crossbeam 2 can be placed on the crossbeam support plate 32 of the multiple leveling devices 3 to continue the erection of the cantilever scaffold. The crossbeam 2 can be fixed by welding or by bolts.

[0041] See Figure 1 , Figure 2 , Figure 3 To facilitate the disassembly, assembly, and reuse of the crossbeam 2, a crossbeam pressure plate 38 is provided above the crossbeam support plate 32. The crossbeam pressure plate 38 is connected to the limiting side plate 34 via a fastening structure. During operation, after the crossbeam 2 is placed on the crossbeam support plate 32 of the leveling device 3, the crossbeam pressure plate 38 is placed above the crossbeam 2. The crossbeam pressure plate 38 is then connected to the limiting side plate 34 via the fastening structure, and the crossbeam 2 is pressed down using the crossbeam pressure plate 38 to fix the crossbeam 2.

[0042] For example, the fastening structure includes U-bolts 39 passing through the crossbeam pressure plate 38 from bottom to top, fastening nuts 40 connected to the ends of the U-bolts 39, and two limiting side plates 34 located inside the U-bolts 39. The crossbeam pressure plate 38 has through holes through which the ends of the U-bolts 39 pass. During operation, after the crossbeam 2 is placed on the crossbeam support plate 32 of the leveling device 3, the crossbeam pressure plate 38 is placed above the crossbeam 2, the two limiting side plates 34 are placed inside the U-bolts 39, and both ends of the U-bolts 39 pass through the through holes of the crossbeam pressure plate 38 from bottom to top. The fastening nuts 40 are then connected to the ends of the U-bolts 39, and after tightening the fastening nuts 40, the crossbeam 2 is pressed down by the crossbeam pressure plate 38, thus fixing the crossbeam 2. Furthermore, there are two U-bolts 39, which are respectively used to install on both sides of the crossbeam 2.

[0043] In other embodiments, the fastening structure may include studs and nuts. The studs are vertically arranged, with their lower ends welded to the limiting side plate 34, and their upper ends passing through the crossbeam pressure plate 38 and connected to the nut. Furthermore, the number of studs may be four, with two studs fixed to one limiting side plate 34 and the other two studs fixed to another limiting side plate 34.

[0044] See Figure 4 The present application provides a cantilever scaffold, including a plurality of spaced main beams 1 and a crossbeam 2 set above the plurality of main beams 1; at least one leveling device 3 is provided on the main beam 1, the leveling device 3 is the leveling device in the above embodiment, the support seat 31 of the leveling device 3 is supported on the main beam 1 and connected to the main beam 1, and the crossbeam 2 is supported on the crossbeam support plate 32 of the leveling device 3.

[0045] The cantilever scaffolding provided in this application embodiment uses a leveling device 3 on the main beam 1 so that the crossbeam 2 is supported on the crossbeam support plate 32 of the leveling device 3. The height adjustment component 33 of the leveling device 3 can quickly level the crossbeam support plate 32, thereby achieving stable and reliable support for the crossbeam 2, thus ensuring the stability of the cantilever scaffolding and improving the erection efficiency of the cantilever scaffolding.

[0046] The above are merely preferred embodiments of this application and are not intended to limit this application in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of this application and within the spirit and principles of this application shall still fall within the protection scope of the technical solution of this application.
