Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to a scaffolding that is easy to adjust. Background Technology

[0002] Scaffolding, as an indispensable construction equipment in fields such as construction, decoration, and maintenance, is mainly used to provide high-altitude work platforms and support workers and construction materials. With the rapid development of the construction industry, the diversification and complexity of construction sites have placed higher demands on the flexibility, adaptability, and safety of scaffolding. Existing scaffolding has limitations in height adjustment, making it difficult to quickly adapt to the needs of different sites, leading to reduced construction efficiency and potentially even safety hazards. Currently, existing scaffolding is typically erected on-site according to the building height, and the completed height is mostly fixed, resulting in poor applicability and an inability to adapt to construction needs at different heights. This necessitates the additional provision of various scaffolding specifications, increasing costs and storage space. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a scaffold that is easy to adjust.

[0004] The technical solution of this utility model is as follows:

[0005] An easily adjustable scaffold includes multiple uprights arranged in pairs at intervals, with a load-bearing plate assembly installed between adjacent pairs of uprights.

[0006] The bearing plate assembly includes four mounting brackets, each of which corresponds to two sets of columns and can slide up and down along the corresponding columns. The mounting brackets can be fixed to the columns at multiple positions in the sliding direction by a fixing device.

[0007] The top of all four mounting frames is equipped with a common support frame, and a support plate is mounted on the support frame.

[0008] To facilitate the installation of the overall scaffolding, four uprights are provided, and the four uprights are arranged in pairs in a rectangular pattern.

[0009] To improve the stability of the fixing device in securing the mounting frame to the column, each mounting frame is fixed to each column by two sets of fixing devices, with the two sets of fixing devices located opposite each other on both sides of the mounting frame.

[0010] The fixing device is specifically designed such that multiple mounting holes are opened on both sides of the column in the vertical direction. The fixing device includes a connecting frame, which is set as a semi-circle, with one side of its plane contacting the mounting frame.

[0011] A fastening bolt is provided through the connection radially, and the fastening bolt can be inserted into the mounting hole. A fastening nut adapted to the fastening bolt is provided on the inner side of the plane end of the connecting frame.

[0012] To facilitate the rotation of the fastening bolt, a knob block is fixed to the outer edge of the fastening bolt, and the knob block is located between the arc-shaped side and the flat side of the connecting frame.

[0013] To improve the stability of the fastening bolt, a support spring is fitted on the outer edge of the fastening bolt, and the support spring is located between the knob block and the arc-shaped side of the connecting frame.

[0014] To facilitate workers climbing onto the support plate, multiple connecting rods are installed at vertical intervals between each group of columns.

[0015] To improve the stability of the support frame, four reinforcing frames are inclinedly arranged between the support frame and the four mounting frames.

[0016] To facilitate the movement of the entire scaffolding, each column is equipped with casters at its base, and these casters are self-locking.

[0017] To improve the stability of the scaffolding when workers stand on the support plates, each lower end is equipped with a support frame, and the bottom end of the support frame is inclined away from the column. The bottom end of the support frame is equipped with a plug.

[0018] The beneficial effects of this utility model are as follows: This utility model is a scaffold that is easy to adjust. Firstly, through the sliding connection between the mounting frame and the upright and the setting of the fixing device, the height of the bearing plate assembly can be quickly adjusted to adapt to the needs of different construction sites. The cooperation of multiple mounting holes on the upright and the fixing device achieves the precision and stability of height adjustment, avoiding the problems of cumbersome adjustment and insufficient precision of traditional scaffolds, saving investment in different specifications of scaffolds, reducing costs and reducing storage space. Secondly, each mounting frame is fixed to the upright by two sets of fixing devices, and the fixing devices are located on both sides of the mounting frame, which enhances the stability and load-bearing capacity of the overall structure. The inclined reinforcing frame between the bearing frame and the mounting frame further improves the rigidity and deformation resistance of the scaffold, ensuring safety in high-altitude operations. Finally, the movable wheels installed at the bottom of the upright allow the scaffold to be easily moved to adapt to the needs of different construction sites. The self-locking function of the movable wheels and the design of the support frame and the plug ensure the stability and safety of the scaffold when it is fixed in use, preventing accidental slippage.

[0028] Example

[0029] As mentioned in the background section, existing scaffolding is usually fixed in height after it is erected, and cannot be flexibly adjusted according to the construction progress on site. This has many drawbacks, which means that a large amount of scaffolding needs to be configured during the construction process, or that it needs to be dismantled and rebuilt, which reduces the construction speed and increases the construction cost and storage space for scaffolding. Therefore, the inventor has improved the existing scaffolding and designed a scaffolding that is easy to adjust in height. The following is a detailed explanation with reference to the illustrations.

[0030] The scaffolding of this utility model includes multiple uprights 1. In this solution, combined with... Figures 1-3 There are four columns 1, arranged in pairs in a rectangular pattern. These columns 1 are spaced apart to form a stable support frame. A load-bearing plate group 2 is installed between two adjacent groups of columns 1 to provide a working platform for workers to stand on and work.

[0031] In this embodiment, each column 1 is equipped with a caster wheel 7 at its bottom. The caster wheel 7 is made of high-strength rubber material and can withstand a large load. The caster wheel 7 is equipped with a self-locking function. The operator only needs to step on the self-locking pedal to fix the scaffolding and prevent it from moving accidentally during operation. In addition, a support frame 8 is also installed at the lower end of each column 1. The bottom end of the support frame 8 is inclined away from the column 1, forming a triangular support structure. The bottom end of the support frame 8 is equipped with a plug rod 9, which can be inserted into the ground to prevent the scaffolding from sliding or tilting on soft or uneven ground.

[0032] Based on the above structure, the support frame 8 and the column 1 are fixed by fixing bolts 10. The fixing position is set at two locations depending on whether the scaffold is in a static construction state or in a moving non-construction state. Two insertion holes 11 are opened at the lower end of the column 1. Depending on the use of the scaffold, the fixing bolts 10 are matched with different insertion holes 11. The fixing bolts 10 are fixed by nuts on the side of the column 1 away from the support frame 8.

[0033] In this embodiment, the support plate assembly 2 includes four mounting frames 21, and a support frame 22 is mounted on the top of the four mounting frames 21. A support plate 23 is laid on the support frame 22 to form a working platform, such as... Figure 4 As shown, each mounting frame 21 is slidably connected to the corresponding column 1 and can move up and down along the column 1, thereby flexibly adjusting the height of the support plate 23. Four reinforcing frames 6 are inclinedly arranged between the load-bearing frame 22 and the mounting frame 21 to enhance the rigidity and stability of the overall structure. The inclined design of the reinforcing frames 6 can effectively distribute the load and prevent the load-bearing frame 22 from deforming or breaking under stress. The support plate 23 is made of anti-slip material, and the surface can be set with anti-slip texture to ensure the safety of construction personnel when working on the platform. The connection between the load-bearing frame 22 and the mounting frame 21 is fixed with bolts, which facilitates disassembly and replacement and improves the maintenance convenience of the scaffolding.

[0034] Based on the above structure, each mounting bracket 21 is connected to the column 1 via a fixing device 3. The column 1 is made of high-strength steel, and its surface has multiple mounting holes 4 along the vertical direction for mating with the fixing device 3 of the mounting bracket 21. Figure 2 The fixing device 3 includes a connecting frame 31 and a fastening bolt 32. The connecting frame 31 is designed to be semi-circular, with one flat side contacting the mounting frame 21, and the curved side being fixed to the column 1 by the fastening bolt 32. The fastening bolt 32 passes through the connecting frame 31 and is inserted into the mounting hole 4 of the column 1, and is locked by a fastening nut 33. The fastening nut 33 is located on the inner side of the flat end of the connecting frame 31 to ensure a firm connection between the mounting frame 21 and the column 1.

[0035] To enhance connection stability, two sets of fixing devices 3 are installed between each mounting bracket 21 and the column 1, located on both sides of the mounting bracket 21. This symmetrical design not only improves load-bearing capacity but also prevents the mounting bracket 21 from tilting or loosening under stress.

[0036] In addition, a knob block 34 is fixed to the outer edge of the fastening bolt 32. The operator only needs to rotate the knob block 34 to tighten or loosen the bolt without additional tools, which significantly improves the adjustment efficiency. Moreover, a support spring 35 is also fitted on the outer edge of the fastening bolt 32. The support spring 35 is located between the knob block 34 and the arc-shaped side of the connecting bracket 31. The support spring 35 can support the knob block 34 and improve the stability of the fixation.

[0037] With the above settings, the mounting bracket 21 can slide up and down along the column 1. By adjusting the position of the mounting bracket 21, the height of the support plate assembly 2 can be quickly changed. The multiple mounting holes 4 on the column 1 provide multiple fixing positions, making height adjustment more precise and flexible.

[0038] Based on the above structure, multiple connecting rods 5 are arranged vertically at intervals between adjacent columns 1. The connecting rods 5 are fixed to the columns 1 with bolts to form a stable frame structure. The setting of connecting rods 5 not only improves the rigidity of the scaffolding and prevents the columns 1 from swaying or tilting during use, but also facilitates workers to climb onto the support plate 23. In order to avoid the connecting rods 5 when the mounting frame 21 slides, the mounting frame 21 is designed with a U-shaped structure, with the opening of the U facing the side of the connecting rods 5, so that the mounting frame 21 can avoid the connecting rods 5 when sliding up and down.

[0039] This utility model of scaffolding is suitable for various construction scenarios, such as high-rise building construction, bridge construction, and interior decoration. Its height adjustment function can quickly adapt to the needs of different sites, reducing the need for multiple specifications of traditional scaffolding and lowering procurement and storage costs. Meanwhile, the design of the moving wheels 7 and support frames 8 allows the scaffolding to be moved and fixed flexibly, improving construction efficiency.
