Background Technology
[0003] Generally, scaffolding is installed and used when constructing a building or carrying out remodeling and building-related construction work.
[0004] These scaffoldings are installed to a height above the ground, and in this case, multiple scaffolding pipes are connected vertically and horizontally.
[0005] However, conventional steel pipes for scaffolding were used in a method where multiple pipes were connected vertically using separate connecting pins and then secured (fastened) with clamps.
[0006] However, existing steel pipes for scaffolding had the problem of taking a long time to install because they were joined by attaching separate clamps to the top and bottom surfaces of the pipes.
[0007] In addition, since the clamp and pipe are joined via a separate pin, if the pin is not inserted, the clamp and pipe will detach, causing serious safety issues.
[0008] In addition, the aforementioned scaffolding steel pipes had a problem in that they posed a risk of safety accidents occurring when workers collided with the pipes while moving along the platform in dark work areas or at night. Prior art literature

Specific details for implementing the invention
[0027] The scaffolding steel pipe of the present invention is designed to shorten work time and prevent safety accidents by forming fitting assembly parts and fixing hooks at both ends, thereby enabling easier assembly or disassembly of multiple steel pipes provided at a construction site.
[0028] In particular, the invention is designed so that reflective film and luminous functional materials are marked on steel pipes to prevent safety accidents, thereby enabling workers to more easily recognize the location of scaffolding structures, preventing safety accidents, and improving the efficiency of structure installation work.
[0029] The present invention is capable of various modifications and may take various forms, and embodiments are to be described in detail in the text. However, this is not intended to limit the present invention to the specific disclosed forms, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.
[0030] The features of the steel pipe for scaffolding according to the present invention can be understood through the embodiments described in detail below with reference to the attached drawings.
[0031] First, the scaffolding steel pipe (10) of the present invention is configured such that, as shown in FIGS. 1 to 3, a plurality of steel pipes are connected vertically or horizontally to form a scaffolding structure at a construction site, and mounting hooks for a platform are assembled to the steel pipes so that a worker can move and work more easily at the construction site.
[0032] The above steel pipe (10) is formed with a connecting pipe (20) having an fitting assembly part (21) at one end of the upper end, and a fixing hook (15) is provided on the outer circumference of the lower end of the steel pipe (10) to be fixed by being caught on the fitting assembly part (21), and a fitting insertion part (13) having an inner diameter corresponding to the outer diameter of the connecting pipe (20) is formed, so that the connecting pipe (20) of the steel pipe (10) is fitted longitudinally into the fitting insertion part (13) of another steel pipe (10) and the fixing hook (15) is fixed by being caught on the fitting assembly part (21).
[0033] In this invention, a steel pipe (10) is generally formed with a length of 2m and is used by continuously assembling the steel pipe (10) in the longitudinal direction at a construction site. In this invention, a connecting pipe (20) that is approximately 10cm long is formed on the upper side of one end of the steel pipe (10). When the connecting pipe (20) is inserted into a fitting insertion part (13) provided at the lower end of another steel pipe (10), a fixing hook (15) formed on the lower outer circumference of the steel pipe (10) is positioned within the fitting insertion part (13) to guide the vertical movement of the steel pipe.
[0034] Here, the steel pipe (10) is formed as a circular pipe, and a connecting pipe (20) is forcibly fitted onto the inner circumference of one end to form a single unit. The present invention also includes at least two pipe fasteners (17) punched at equal intervals on the outer circumference of the end into which the connecting pipe (20) is inserted, thereby making the connecting pipe (20) more robustly a single unit.
[0035] The fitting assembly part (21) formed in the connecting pipe (20) of the present invention has a vertical slide groove (22) formed from the upper end of the connecting pipe (20) to the center in the drawing, and the vertical slide groove (22) is formed by pressing the outer circumference of the connecting pipe (20) in a curved direction in the inner diameter direction so that a fixing hook (15) protruding in a spherical shape from the inner circumference of the steel pipe (10) which is punched from the outer circumference is fitted into the vertical slide groove (22).
[0036] Accordingly, when a connecting pipe (20) formed on the upper side of a steel pipe (10) is inserted into the lower side of another steel pipe (10), if the positions of the vertical slide groove (22) and the fixing hook (15) are not aligned on a vertical line, the tip of the connecting pipe is caught on the fixing hook (15), and the sliding movement is interrupted. However, if the connecting pipe (20) is rotated horizontally so that the positions of the vertical slide groove (22) and the fixing hook (15) are aligned on a vertical line as in FIG. 4a, the fixing hook (15) moves along the vertical slide groove (22) as in FIG. 5a, and the connecting pipe (20) of the other steel pipe is completely inserted into the lower side of the steel pipe (10).
[0037] And, since the above-mentioned fitting assembly part (21) is configured to have an 'L' shape in which a fixing fitting hole (24) is formed horizontally through one end of the vertical slide groove (22), when the connecting pipe (20) of another steel pipe is fully inserted into the lower part of the steel pipe (10), as shown in FIGS. 4b and FIGS. 5b, the other steel pipe (10) is rotated horizontally so that the fixing hook (15) moves toward the fixing fitting hole (24), thereby configuring the steel pipes (10) to be mutually connected.
[0038] That is, when the connecting pipe (20) is moved with the hemispherical fixing hook (15) fitted into the curved vertical slide groove (22) and is positioned at the bottom of the vertical slide groove (22), the connecting pipe (20) of another steel pipe (10) is fully inserted into the steel pipe (10), and then one of the steel pipes (10) is rotated horizontally so that the fixing hook (15) is fitted into the fixing fitting hole (24), thereby connecting the steel pipes to each other.
[0039] At this time, the fixing hole (24) formed horizontally at the lower end of the vertical slide groove (22) may be formed in a rightward direction like an 'L' shape or in a leftward direction like an inverted 'L' shape, and the horizontal direction of the fixing hole (24) can be applied in various ways according to the requirements of those skilled in the art, so it is not limited to a specific one.
[0040] Additionally, in the above-mentioned fixed fitting hole (24), a connecting guide groove (23) is formed at the lower end of the vertical slide groove (22) and cut in the direction of the fixed fitting hole (24) so that the fixed hook (15) fitted into the curved vertical slide groove (22) can move horizontally in the direction of the fixed fitting hole (24), thereby allowing the fixed hook (15) fitted into the vertical slide groove (22) to move more smoothly horizontally in the direction of the fixed fitting hole (24) through the connecting guide groove (23).
[0041] In addition, a locking tab (25) having a convex shape is formed protruding from the lower or upper surface of the above-mentioned fixed fitting hole (24), so that the fixed locking tab (15) of the horizontally moving fitting insertion part (13) passes over the locking tab (25) and is locked, and the fixed locking tab (15) is not separated unless a certain external force is applied, thereby allowing the steel pipe to be connected more stably.
[0042] Here, the locking tab (25) formed in the fixed fitting hole (24) is formed in a rectangular shape having a protrusion height of 3 mm and a width of 4 to 6 mm as an example, so that the distance the fixed locking tab (15) moves by being inserted into the locking tab (25) during the process of moving horizontally along the fixed fitting hole (24) is extended, and the steel pipe (10) is separated by applying a certain external force and rotating it in the reverse direction, thereby preventing the steel pipe from easily separating due to vibration and impact, and maximizing safety.
[0043] In addition, the present invention also includes the formation of an anti-slip device (33) on the outer circumference of the steel pipe (10) using knurling or a band with high friction, so that the worker can more easily grip and rotate the steel pipe during the process of connecting and disassembling the steel pipe (10).
[0044] In addition, a highly visible reflective film is attached to the outer periphery of the above steel pipe (10), or a reflective member (31) colored with a luminous functional material is provided, so that the above steel pipe can be assembled to easily install a scaffolding structure even in a dark work area or at night, and after work, when a worker assembles a platform on the scaffolding structure and moves along the platform, the worker can secure a view of the location of the above steel pipe, thereby maximizing safety to prevent collisions.
[0045] The above anti-slip member (33) and reflective member (31) are arranged in a continuous strip shape at both ends and the center of the steel pipe (10) so that the worker can more easily grip or check the position.
[0046] Meanwhile, the steel pipe (10) is formed with a standardized length between 1m and 6m. For example, on a steel pipe with a length of 2m, anti-slip bands (33) with a circular shape of approximately 20mm are arranged in three rows at intervals of approximately 10mm at both ends, and anti-slip bands (33) with a circular shape of approximately 20mm are arranged in six rows at intervals of approximately 10mm in the center to prevent the worker from slipping while gripping the steel pipe.
[0047] Additionally, at the 10mm interval between the above anti-slip members (33), a reflective member (31) is attached with a reflective film of a bright color (yellow, orange, green, fluorescent, or luminous) capable of glowing in the dark and reflecting light, or is painted by spraying or laser device to ensure visibility and improve the work efficiency of installing scaffolding structures. The composition of the reflective member (31) and the composition of the painting, etc., can be applied in various ways according to the requirements of those skilled in the art, so it is not limited to a specific one.
[0048] Accordingly, by configuring the anti-slip member (33) and the reflective member (31) to be repeated at least twice consecutively on both ends and the central outer periphery of the above steel pipe (10), visibility is ensured even in dark construction sites, thereby preventing various types of accidents (collision, fall, dropping, collision) in advance and ensuring safety, and improving the convenience of connecting and disconnecting the steel pipe (10) for the installation of scaffolding structures, thereby increasing work efficiency.
[0049] In the above (integrated) steel pipe, when connecting the steel pipe to another steel pipe, the structure is such that when the male and female parts are inserted and turned to the right, it locks in one go.
[0050] According to the present invention, a double locking device is implemented by forming a projection (for locking) with a height of 3 mm and a width of 6 mm (see reference, example, not limited thereto) to prevent automatic detachment and automatic loosening after connecting male and female pipes, and in this respect, it is differentiated from the prior art.
[0051] As described above, the embodiments explained are the most preferred examples of the present invention, but are not limited to the above embodiments, and it is obvious to those skilled in the art that various modifications are possible within the scope of the technical spirit of the present invention.
