Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to an attached lifting scaffolding position fixing device for cantilever components. Background Technology

[0002] Climbing formwork relies on attachment supports to be firmly connected to the building structure in order to support its own weight and the loads generated during construction. These attachment supports are firmly installed on the building's structural components such as columns, beams, and walls using connectors such as screws and nuts.

[0003] However, due to the often complex and varied external contours of buildings, the attachment supports for climbing scaffolds may encounter outward-extending cantilever structures such as balconies and canopies during installation. As a critical support point for the external scaffolding of high-rise buildings, the stability and safety of the climbing scaffolding location directly affect the smooth progress of the entire construction process and the safety of on-site workers. Traditionally, such as Figure 5 The climbing scaffolding is often directly fixed to the edge secondary beam of the cantilevered structure of the building by pre-embedded through-wall bolts. However, although this installation method seems simple, it actually poses a significant safety hazard due to stress.

[0004] Specifically, when the climbing scaffold is attached only to the edge secondary beam of the cantilever structure, rather than to the more stable inner frame beam or connecting beam, its stress distribution becomes relatively simple and concentrated. Since the edge secondary beam typically has lower design load-bearing capacity and shear strength compared to the inner frame beam or connecting beam, it is highly susceptible to deformation or damage under the load of the climbing scaffold and the construction loads above it.

[0005] More seriously, this stress distribution can also lead to structural problems such as cracking at the root of the cantilevered member. Due to the concentrated load generated by the climbing scaffolding location, the root of the cantilevered member will be subjected to additional bending moment and shear force, thereby increasing the risk of root cracking. Once root cracking occurs, it will not only seriously affect the overall structural safety of the building, but may also trigger more serious safety accidents. Utility Model Content

[0006] This utility model provides a fixed device for the fixed position of an attached lifting scaffold at a cantilevered component, in order to solve the technical problems of low fixed bearing capacity and safety hazards in the force-bearing method of the existing attached lifting scaffold at a cantilevered component.

[0007] To solve the above problems, the attachment-type lifting scaffolding position fixing device at the cantilever component provided by this utility model adopts the following technical solution:

[0008] It includes a channel steel frame fixed to one side of the climbing frame by a connector. The end of the channel steel frame close to the climbing frame is provided with an adjusting rod that can be detachably connected to the upper structural beam. The length of the adjusting rod is adjustable and an adjusting support rod is hinged to the lower section of the outer wall of the adjusting rod. The bottom surface of the adjusting support rod abuts against the upper surface of the channel steel frame and the adjusting support rod is perpendicular to the channel steel frame.

[0009] The adjusting support rod includes a central adjusting rod and an adjusting sleeve sleeved outside the central adjusting rod, and a float plate is floatingly connected to the bottom surface of the adjusting sleeve.

[0010] Furthermore, the adjusting linkage includes a pull rod and an adjustable connecting rod at both ends of the pull rod. The free end of the connecting rod is provided with a connecting lug. The channel steel frame is provided with a first connecting seat for connecting with the adjacent connecting lug. The upper structural beam is provided with a second connecting seat for connecting with the adjacent connecting lug.

[0011] Furthermore, the end of the pull rod is a hollow sleeve structure, one end of the connecting rod extends into the sleeve and is connected to the sleeve by threads, and the free end of the connecting rod is rotatably connected to the connecting lug.

[0012] Furthermore, a positioning nut is fitted onto the connecting rod.

[0013] Furthermore, the lower section of the outer wall of the adjusting rod is provided with a hinge lug for hinged connection with the top end of the central adjusting rod.

[0014] Furthermore, the outer wall of the central adjusting rod and the inner wall of the adjusting sleeve are both threaded, and the bottom end of the adjusting sleeve is rotatably connected to a bearing with a seat, and the float plate is floatingly connected to the bottom surface of the bearing with a seat.

[0015] Furthermore, a spring column is provided between the float plate and the bearing seat.

[0016] The beneficial effects of this utility model are:

[0017] 1. In this utility model, through the synergistic action of the adjusting connecting rod and the adjusting support rod, the entire device can more accurately distribute and transfer loads, thereby enhancing the structural bearing capacity of the scaffolding system. The adjusting support rod is perpendicular to the channel steel frame and hinged to the adjusting connecting rod, with its bottom surface abutting against the upper surface of the channel steel frame. The whole structure forms a stable triangular support structure, effectively enhancing the stability of the adjusting connecting rod and its connecting parts. The adjusting support rod prevents the adjusting connecting rod from bending or deforming due to excessive force, thus maintaining the stability of the entire structure.

[0018] 2. In this utility model, the lengths of both the adjusting connecting rod and the adjusting support rod are adjustable, allowing the device to adapt to building structures of different heights and shapes. This design not only improves the versatility and flexibility of the device but also facilitates installation and adjustment work for construction personnel.

[0019] 3. In this utility model, the elastic floating setting of the float plate can, on the one hand, adapt to different installation environments and stress conditions, ensuring the stability of the adjustment support rod; on the other hand, the elastic effect of the spring column can also absorb and mitigate the impact and vibration from the outside, protecting the entire adjustment support structure from damage.

Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] The number of any elements in the accompanying drawings is for illustrative purposes only and not as a limitation, and any naming is for distinction only and has no limiting meaning.

[0030] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0031] An embodiment of the attachment-type lifting scaffolding position fixing device at the cantilever component provided by this utility model:

[0032] like Figures 1 to 4 As shown,

[0033] The system includes a channel steel frame 3 fixed to one side of the climbing frame 2 via a connector 1. The end of the channel steel frame 3 near the climbing frame 2 is provided with an adjusting rod 5 that can be detachably connected to the upper structural beam 4. The length of the adjusting rod 5 is adjustable, and an adjusting support rod 6 is hinged to the lower section of the outer wall of the adjusting rod 5. The bottom surface of the adjusting support rod 6 abuts against the upper surface of the channel steel frame 3, and the adjusting support rod 6 is perpendicular to the channel steel frame 3.

[0034] By adjusting the connecting rod 5 and the adjusting support rod 6, the load-bearing capacity of the structure is improved, allowing for more precise distribution and transfer of loads at the location of cantilevered components, thereby enhancing the structural load-bearing capacity of the entire scaffolding system.

[0035] The adjusting support rod 6 is perpendicular to the channel steel frame 3 and hinged to the adjusting connecting rod 5, with its bottom surface abutting against the upper surface of the channel steel frame 3. This forms a stable triangular support structure, effectively enhancing the stability of the adjusting connecting rod 5 and its connecting parts. The adjusting support rod 6 prevents the adjusting connecting rod 5 from bending or deforming due to excessive force, thus maintaining the stability of the entire structure.

[0036] In this embodiment, the adjusting rod 5 includes a pull rod 51 and an adjustable connecting rod 52 at both ends of the pull rod 51. The free end of the connecting rod 52 is provided with a connecting ear 53. The channel steel frame 3 is provided with a first connecting seat 31 for connecting with the adjacent connecting ear 53. The upper structural beam 4 is provided with a second connecting seat 41 for connecting with the adjacent connecting ear 53.

[0037] The hinged connection between the connecting ear 53 and the first connecting seat 31 or the second connecting seat 41 improves the flexibility of the installation of the adjusting rod 5. Construction personnel can quickly install the adjusting rod 5 into place without tedious adjustments and positioning.

[0038] The pull rod 51 has a hollow sleeve structure at its end. One end of the connecting rod 52 extends into the sleeve and is connected to the sleeve by a thread. The free end of the connecting rod 52 is rotatably connected to the connecting lug 53.

[0039] By forming a sleeve at the end of the pull rod 51 and threading it to the connecting rod 52, the overall length of the adjusting rod 5 can be adjusted by adjusting the length of the connecting rod 52 screwed into the sleeve.

[0040] The adjustable length of the adjusting link 5 allows the device to adapt to building structures of different heights and shapes, improving its versatility and flexibility.

[0041] The threaded connection makes the installation and removal of the tie rod 51 and the connecting rod 52 simple and quick. When maintenance or replacement of parts is required, the construction personnel can easily remove the connecting rod 52 for inspection or repair before reinstalling it.

[0042] The connecting rod 52 is fitted with a positioning nut 521 to facilitate auxiliary adjustment and positioning.

[0043] In this embodiment, the adjusting support rod 6 includes a central adjusting rod 61 and an adjusting sleeve 62 sleeved outside the central adjusting rod 61. A float plate 63 is floatingly connected to the bottom surface of the adjusting sleeve 62.

[0044] Specifically, both the outer wall of the central adjusting rod 61 and the inner wall of the adjusting sleeve 62 are threaded, and the bottom end of the adjusting sleeve 62 is rotatably connected to a seated bearing 621. This threaded connection facilitates relative adjustment between the central adjusting rod 61 and the adjusting sleeve 62, thereby adjusting the overall height of the adjusting support rod 6. Adjustment of the adjusting support rod 6 follows the adjusting lug of the adjusting connecting rod 5, improving operational flexibility. The seated bearing 621 structure provides rotational support for the adjusting sleeve 62. As the seated bearing 621 gradually tightens against the channel steel frame 3, the rotational engagement between the seated bearing 621 and the adjusting sleeve 62 prevents interference during adjustment, ensuring smooth adjustment without being hindered by friction or resistance.

[0045] The float plate 63 is floatingly connected to the bottom surface of the bearing 621. Specifically, a spring column 64 is provided between the float plate 63 and the bearing 621. Through the elastic floating setting of the float plate 63, on the one hand, it can adapt to different installation environments and stress conditions, ensuring the stability of the adjusting support rod 6; on the other hand, the elastic effect of the spring column 64 can also absorb and mitigate impacts and vibrations from the outside, protecting the entire adjusting support structure from damage.

[0046] The lower section of the outer wall of the adjusting rod 5 is provided with a hinge lug 54 for hinged to the top of the central adjusting rod 61.

[0047] In this embodiment, the installation process of the fixed device for the attached lifting scaffolding at the cantilever component involves pre-embedding connecting bolts for the channel steel frame 3 in the structural beam of this floor and pre-embedding connecting bolts for installing the second connecting seat 41 in the upper structural beam 4 during the construction of the main building structure. A pad is provided between the channel steel frame 3 and the structural beam of this floor. Subsequently, the length of the adjusting rod 5 is adjusted according to the distance between the first connecting seat 31 and the second connecting seat 41, and the adjusting rod 5 is installed. After the adjusting rod 5 is installed and tightened, the length of the adjusting support rod 6 is adjusted accordingly, so that the floating plate 63 is pressed against the channel steel frame 3.
