Abstract
Description
Technical Field
[0001] This invention relates to the field of scaffolding technology, and in particular to a retractable and anti-slip steel scaffolding board that is resistant to being stepped on and warped. Background Technology
[0002] As an important component of scaffolding systems in building construction, scaffold boards are mainly used to provide working platforms for construction workers and temporary storage areas for materials. Currently, steel scaffold boards are gradually replacing traditional wooden scaffold boards due to their advantages such as high load-bearing capacity, good durability, and excellent fire resistance, and are widely used in various building construction scenarios such as high-rise residential buildings, commercial complexes, and bridge projects.
[0003] However, in actual construction, existing steel scaffold boards, due to their fixed length, are difficult to adapt to the erection needs of scaffolds with different spans. Construction sites often need to have scaffold boards of various specifications, which not only increases the difficulty of material management but also reduces erection efficiency. Furthermore, traditional scaffold boards are prone to warping and deformation due to single-end stress during use, posing safety hazards. At the same time, some scaffold boards have insufficient anti-slip properties, making it easy for personnel to slip and fall when walking in wet or muddy conditions.
[0004] To address this, a retractable and anti-slip steel scaffolding board that prevents stepping and warping is proposed. Summary of the Invention
[0005] In view of this, the present invention provides a retractable and anti-slip steel scaffolding board that is resistant to being stepped on and warped, in order to solve or alleviate one of the technical problems existing in the prior art, and at least provide a beneficial alternative.
[0006] The technical solution of this invention is implemented as follows: a retractable and anti-slip steel scaffold board, including an outer scaffold board, an inner scaffold board slidably connected to the inner side wall of the outer scaffold board, two hooks symmetrically fixedly connected to one end of the outer scaffold board and the inner scaffold board, a reinforcing sleeve fixedly connected to the outer side wall of the outer scaffold board, a telescopic positioning baffle fixedly connected to the bottom of the outer scaffold board, anti-slip protrusions uniformly provided on the upper surface of the outer scaffold board and the inner scaffold board, and reinforcing holes symmetrically opened at one end of the outer scaffold board and the inner scaffold board.
[0007] A further preferred embodiment: the bottom of the hook is provided with a slot.
[0008] A further preferred embodiment: the reinforcing hoop is located at the end of the outer scaffold board near the inner scaffold board.
[0009] A further preferred embodiment: the top and side walls of the outer and inner scaffold boards are provided with support reinforcement structures.
[0010] Further preferred: the outer scaffold board and the inner scaffold board are stamped from Q235 galvanized steel sheet.
[0011] The embodiments of the present invention have the following advantages due to the adoption of the above technical solutions: I. This invention, by setting up mutually slidingly connected outer and inner scaffold boards and strengthening the connection with reinforcing hoops, allows the overall length of the scaffold boards to be freely adjusted within a certain range, which can flexibly adapt to the erection needs of scaffolds with different spans, reduce the reliance on the preparation of scaffold boards of various specifications on the construction site, and improve the versatility and erection efficiency of the scaffold boards.
[0012] Second, this invention provides a telescopic positioning baffle at the bottom of the outer scaffold board, which can lock the scaffold board after it has been extended or retracted into place, preventing accidental slippage during use and ensuring structural stability.
[0013] Third, by uniformly setting anti-slip protrusions on the upper surfaces of the outer and inner scaffold boards, the present invention increases the friction between the sole of the shoe and the board surface, and can maintain good anti-slip performance even in complex working conditions such as wet and muddy conditions, reducing the safety risk of construction workers slipping.
[0014] Fourth, by setting support and reinforcement structures on the top and side walls, the present invention forms a reinforced cross-section design, which can effectively disperse the stress of stepping, prevent the deformation of stepping when subjected to force at one end, and improve walking safety and overall load-bearing capacity.
[0015] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the invention will become readily apparent from the accompanying drawings and the following detailed description.

[0019] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0021] like Figures 1-6 As shown, this embodiment of the invention provides a retractable and anti-slip steel scaffold board that is resistant to being stepped on and warped. It includes an outer scaffold board 11, and an inner scaffold board 12 is slidably connected to the inner side wall of the outer scaffold board 11. The inner scaffold board 12 can slide back and forth along the length direction inside the outer scaffold board 11, thereby realizing the extension and retraction adjustment of the overall length of the scaffold board to adapt to the erection requirements of scaffolding with different spans.
[0022] Two hooks 13 are symmetrically fixedly connected to one end of the outer scaffold board 11 and the inner scaffold board 12. A reinforcing sleeve 14 is fixedly connected to the outer side wall of the outer scaffold board 11. The reinforcing sleeve 14 not only guides the telescopic end to ensure smooth sliding of the inner scaffold board 12, but also enhances the structural strength of the end of the outer scaffold board 11 to prevent the telescopic part from deforming due to force.
[0023] The bottom of the outer scaffold board 11 is fixedly connected to a telescopic positioning baffle 15. Anti-slip protrusions 16 are evenly provided on the upper surfaces of the outer scaffold board 11 and the inner scaffold board 12. Reinforcing holes 17 are symmetrically opened at one end of the outer scaffold board 11 and the inner scaffold board 12. The anti-slip protrusions 16 are used to increase the friction between the board surface and the sole of the shoe, so that they can maintain good anti-slip performance in wet, muddy or dusty conditions, reducing the risk of slipping when walking. The reinforcing holes 17 are used to strengthen the fixed scaffold board structure and further improve the stability of the scaffold structure.
[0024] In this embodiment, specifically: the bottom of the hook 13 is provided with a slot. The hook 13 is used to hang the scaffold board on the scaffold crossbar to achieve quick installation and reliable fixation. The slot can form a locking fit with the scaffold crossbar to prevent the hook 13 from slipping during use and improve connection stability.
[0025] In this embodiment, specifically: the reinforcing sleeve 14 is set at the end of the outer scaffold board 11 near the inner scaffold board 12. The reinforcing sleeve 14 is located at the connection part of the telescopic structure, which can effectively constrain the relative position of the inner and outer scaffold boards 11 and improve the structural stability of the telescopic section.
[0026] In this embodiment, specifically: the top and side walls of the outer scaffold board 11 and the inner scaffold board 12 are provided with supporting reinforcement structures, and the cross-sectional shapes of the outer scaffold board 11 and the inner scaffold board 12 are as follows: Figure 6 As shown, the support and reinforcement structure is set in the form of reinforcing ribs or folded edges, so that the cross section of the scaffold board forms a reinforced profile, which can effectively disperse the stress of stepping, improve the overall load-bearing capacity, and prevent the occurrence of warping.
[0027] In this embodiment, specifically: the outer scaffold board 11 and the inner scaffold board 12 are stamped from Q235 galvanized sheet. Q235 galvanized sheet has good strength, toughness and corrosion resistance. It is integrally formed by stamping process, which not only ensures structural strength, but also realizes lightweight design, which is convenient for handling and installation.
[0028] In operation, this invention works as follows: The inner scaffold plank 12 is smoothly pulled along the guide groove of the reinforcing sleeve 14 according to the actual span requirements of the scaffold. When the telescopic section reaches the target length, the scaffold plank is hooked onto the scaffold crossbar using symmetrically arranged hooks 13. The slot design at the bottom of the hook 13 engages with the crossbar, and the steel wire rope (not shown in the figure) inserted through the reinforcing hole 17 forms a double anti-derailment mechanism, improving the stability of the erection.
[0029] When construction workers walk on it, the anti-slip protrusions 16 increase friction, maintaining a high level of friction even when the surface is covered with mud or rainwater. Simultaneously, the supporting reinforcement structure (such as longitudinal stiffeners and sidewall folds) forms a box-shaped bending section, evenly distributing the stepping load along the plate and suppressing warping deformation caused by unilateral stress. The Q235 galvanized sheet, stamped into a substrate, has excellent impact resistance, and the galvanized layer resists corrosion from construction site media. Regular application of grease to expansion joints ensures smooth, long-term sliding.
[0030] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
