Modular scaffolding system with protective components

Abstract

The present invention relates to a scaffolding system comprising multiple scaffolding modules that can be assembled together, wherein each scaffolding module is provided to form a worker accommodation space by connecting multiple wire members together, and has a frame having a scaffolding board portion and multiple side wall portions installed upright relative to the scaffolding board portion; and a protective member having a wooden board layer fixed and provided to cover at least a portion of the side wall portion of the frame with a wooden board-like body, and a hard elastic layer coated on one surface of the wooden board layer with a polyurea material. This not only prevents the scattering of dust and the diffusion of noise, but also ensures that even if debris from a demolished building falls onto the scaffolding module, the reinforced protective member can withstand the load of the building debris, thereby preventing injury to workers in the accommodation space and damage to the scaffolding module, and creating a safe working environment.

Description

Technical Field

[0001] The present invention relates to a modular scaffold system installed for stable work of workers at a building demolition site or the like.

Background Art

[0002] A scaffold system refers to a temporary structure installed so that workers can climb up and perform necessary work at a building demolition site, a construction site, or the like. The scaffold system forms an accommodation space so that workers can perform stable work while moving.

[0003] A modular scaffold system adaptively connects horizontally or stacks vertically scaffold modules mass-produced to have a predetermined size according to the site situation. Such a modular scaffold system is superior to a conventional scaffold system in which workers connect steel pipes one by one vertically in terms of ease of installation and disassembly of scaffold modules, rigidity and safety of scaffold modules, and the like.

[0004] Scaffold modules not only need to prevent the scattering of dust and the diffusion of noise, but also, for example, when a high-load building wreckage collapses the scaffold module during building demolition work, there is a need for an alternative to the problem that the building wreckage hits and injures workers in the accommodation space or the scaffold module is damaged and cannot withstand the load of the building wreckage.

[0005] Therefore, there is an increasing demand for a modular scaffold system that can not only prevent the scattering of dust and the diffusion of noise, but also prevent damage caused by high-load building wreckage and create a safe working environment.

Summary of the Invention

Problems to be Solved by the Invention

[0006] The objective of the present invention is to provide a scaffolding system that not only prevents the scattering of dust and the spread of noise, but also prevents injuries to workers and damage to the scaffolding modules even if demolition debris falls onto the scaffolding modules, thereby creating a safe working environment. [Means for solving the problem]

[0007] The aforementioned object of the present invention can be achieved by a scaffolding system comprising a plurality of scaffolding modules that can be assembled together, wherein the scaffolding modules are provided to connect a plurality of wires to each other to form a space for workers, and the scaffolding modules are frames having scaffolding boards and a plurality of side walls installed upright relative to the scaffolding boards; and a protective member comprising a wooden board layer fixedly arranged to cover at least a portion of the side walls of the frame with a wooden board-like body, and a hard elastic layer coated on one surface of the wooden board layer with a polyurea material.

[0008] According to this, the plate-shaped protective members not only prevent the scattering of dust and the spread of noise, but even if the demolition debris of the building falls onto the scaffolding module, the reinforced protective members can withstand the load of the building debris, thus preventing injuries to workers in the containment space and damage to the scaffolding module, and creating a safe working environment.

[0009] The protective member is superimposed on the rigid elastic layer and further includes an auxiliary coating layer comprising at least one material from polyurethane, PVC, epoxy, and silicone, wherein the rigid elastic layer is partially applied to one surface of the wooden board layer.

[0010] Thus, by using a lower-cost auxiliary coating layer in conjunction with a rigid elastic layer, it is possible to minimize the amount and number of coats of the expensive rigid elastic layer while ensuring the rigidity of the protective member, thereby improving cost efficiency.

[0011] The protective member is formed by plasma-treating the surface of the wooden board layer and then applying the hard elastic layer.

[0012] According to this method, activating the surface molecules of the wood board layer can improve the adhesion of the hard elastic layer to the surface of the wood board layer. Improved adhesion of the hard elastic layer not only enhances the rigidity of the protective member, but also minimizes the amount and number of coats required for the hard elastic layer, thereby improving cost-effectiveness.

[0013] The system further includes corner modules installed and joined between a pair of scaffolding modules that intersect at their horizontal edges, the corner modules including a plurality of vertical columns forming a side wall; safety bars installed horizontally between the pair of vertical columns; and safety bar attachment sections, each provided on an opposing face of the pair of vertical columns and having a U-shaped body with an opening, to which both ends of the safety bars are detachably secured through the opening.

[0014] Thus, by using safety bars and safety bar attachment / detachment parts, the storage spaces of a pair of scaffolding modules can be easily connected regardless of the installation direction of the corner module relative to the pair of scaffolding modules, thereby improving cost efficiency and enhancing safety by guiding workers moving through the storage spaces of a pair of scaffolding modules so that they do not go in a direction that is not connected to the pair of scaffolding modules.

[0015] The wire material is tubular, and one of the pair of scaffolding modules stacked vertically has a stacking housing portion at the end of the tubular body, while the other frame has a stacking ring portion that protrudes to be housed in the stacking housing portion and has a ring shape that narrows in width along the direction of protrusion.

[0016] Thus, the ring shape of the stacking ring facilitates the stacking of scaffolding modules. Furthermore, since the stacking ring performs all the functions of transporting and stacking the scaffolding modules, it can improve cost efficiency compared to having separate configurations for each function.

[0017] The system includes a soundproofing panel that is plate-shaped, installed along the upper edge of the frame, and positioned to be inclined at a predetermined angle. This system can reduce the damage to the surrounding area caused by noise from building demolition work.

[0018] The wood-like material includes medium-density fiberboard (MDF). Because medium-density fiberboard has more uniform surface properties compared to other wood-like materials, it can improve the coating quality of the hard elastic layer.

[0019] The object of the present invention described above can also be achieved by a scaffolding system comprising a plurality of scaffolding modules that can be assembled together, wherein each scaffolding module is provided to form a worker accommodation space by connecting a plurality of wires together, and includes a frame having a scaffolding board portion and a plurality of side wall portions erected upright relative to the scaffolding board portion, wherein the wires are tubular bodies, and one of the frames of a pair of the scaffolding modules stacked vertically has a stacking accommodation portion at the end of the tubular body, and the other frame includes a stacking ring portion that protrudes to be accommodated in the stacking accommodation portion and has a ring shape that narrows in width along the direction of protrusion.

[0020] Thus, the ring shape of the stacking ring facilitates stacking between scaffolding modules, and since the stacking ring performs all the functions of transporting and stacking the scaffolding modules, it can improve cost efficiency compared to having separate configurations for each function. [Effects of the Invention]

[0021] According to the present invention, a scaffolding system can be provided in which a plate-shaped protective member is attached to the scaffolding module to prevent dust scattering and noise diffusion, and the protective member has enhanced rigidity, thereby preventing injury to workers and damage to the scaffolding module even if building debris falls onto it, thus creating a safe working environment.

Embodiments for Carrying Out the Invention

[0023] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. This is for the purpose of explaining in detail to such an extent that those having ordinary knowledge in the technical field to which the present invention pertains can easily implement the invention, and thereby, the technical idea and scope of the present invention are not limited.

[0024] FIG. 1 shows a scaffold system 1 provided by assembling a plurality of scaffold modules 2 according to an embodiment of the present invention, FIG. 2 shows an example of the scaffold module 2 of FIG. 1, and FIG. 3 shows an example of a protective member 7 provided on the scaffold module 2 of FIG. 1. Hereinafter, the scaffold system 1 according to this embodiment will be described in detail with reference to FIGS. 1 to 3.

[0025] The scaffolding system 1 according to this embodiment is a temporary structure installed at building demolition sites and consists of multiple scaffolding modules 2 that can be assembled together. For example, when demolishing a building located in a building area P, if the scaffolding modules 2 are assembled together to surround a part of the periphery of the building area P, workers can move freely between the accommodation spaces S formed by the scaffolding modules 2 and perform the work necessary for building demolition. The assembly of the scaffolding modules 2 can include interconnecting the scaffolding modules 2 in the X-axis or Y-axis direction and interconnecting them in the Z-axis direction. Cranes, hoists, etc., can be used for assembling the scaffolding modules 2. In this way, the scaffolding system 1 can be realized in a modular form, and is superior to conventional scaffolding systems in terms of ease of installation and dismantling of the scaffolding modules 2, as well as the rigidity and safety of the scaffolding modules 2, compared to conventional scaffolding systems in which workers connect steel pipes one by one vertically. However, the scaffolding system 1 is not limited to being installed at building demolition sites, and can also be installed at construction sites to allow workers to perform the work necessary for building construction.

[0026] More specifically, the scaffolding module 2 of the scaffolding system 1 includes a frame 6 and protective members 7. The frame 6 is provided to form a worker accommodation space S by connecting a plurality of wire members 3 to each other, and has a scaffolding board section 4 and a plurality of side wall sections 5 that are installed upright relative to the scaffolding board section 4.

[0027] Multiple wires 3 can be welded together to form a workspace S for workers. However, the multiple wires 3 may also be connected by connecting members such as clamps, in addition to welding. The wires 3 may be provided as rectangular tubular bodies, but are not limited to this, and may be provided as circular or other tubular bodies.

[0028] The scaffolding board section 4 may be provided in a plate shape parallel to the X-axis and Y-axis directions so that workers can move stably within the accommodation space S. In Figure 2, four side wall sections 5 are shown to be erected vertically from the edge of the scaffolding board section 4 in the Z-axis direction, but this is not limited to this, and additional vertical sections may be erected from areas other than the edge of the scaffolding board section 4.

[0029] The protective member 7 can prevent the scattering of dust generated during building demolition work and prevent the diffusion of noise. In particular, the protective member 7 has a wooden board layer 21 fixedly installed so as to cover at least a portion of the side wall portion 5 of the frame 6, and a hard elastic layer 22 made of polyurea material applied to one surface of the wooden board layer 21. For example, if the side wall portion 5 includes an inner side wall portion 11 and an outer side wall portion 12 that face each other in the X-axis direction, the wooden board layer 21 can be fixedly installed so as to cover at least a portion of the inner side wall portion 11. The inner side wall portion 11 can be more adjacent to the building area P than the outer side wall portion 12. In Figure 2, the inner side wall portion 11 is shown to be covered by two protective members 7, but it is not limited to this, and the inner side wall portion 11 can be completely covered by one protective member 7 that is further extended in the Y-axis direction, or it can be divided and covered by three or more protective members 7 that are further reduced in the Y-axis direction.

[0030] The wooden board layer 21 has the advantage of easily absorbing physical impacts and recovering to its original state even if deformed by impact, because it possesses the elasticity, flexibility, and resilience of wood. On the other hand, the metal plate has the disadvantage of being easily deformed by physical impacts and having difficulty recovering to its original state, due to the high fluidity of the metal.

[0031] The rigid elastic layer 22 plays a role in increasing the rigidity limit against impact. In other words, when using a protective member 7 in which the rigid elastic layer 22 is applied to the wooden board layer 21, the wooden board layer 21 will not be damaged even if an impact exceeding the rigidity limit of the wooden board layer 21 itself is applied. On the other hand, if a physical impact is applied to the wooden board layer without the rigid elastic layer 22 applied to it, the wooden board layer can easily be damaged if the impact exceeds the rigidity of the wooden board layer itself.

[0032] Polyurea, used as the material for the rigid elastic layer 22, is typically used as a waterproofing agent for water tanks and other applications where excellent waterproofing properties are required to prevent liquid penetration. However, compared to the case where polyurethane, which has a similar chemical structure, is applied to the wooden board layer 21, polyurea can provide the wooden board layer 21 with higher tensile and bending strength, thereby maximizing the rigidity limit against impact.

[0033] Polyurea can be applied to the wood board layer 21 by methods such as spray coating or casting coating. The spray coating method involves spraying the polyurea onto the surface of the wood board layer 21 using a high-pressure spray machine, while the casting coating method involves applying the polyurea to the surface of the wood board layer 21. Polyurea can be applied to one of the two surfaces of the wood board layer 21, but it can also be applied to both surfaces to further enhance the rigidity-improving effect.

[0034] Thus, the protective member 7 not only prevents the scattering of dust and the diffusion of noise, but its rigidity is also improved by the hard elastic layer 22, which maximizes the prevention of damage to the protective member 7 even if building debris falls onto the scaffolding module 2 during building demolition work. Therefore, it is possible to prevent injuries to workers in the containment space S and damage to the scaffolding module 2 caused by building debris, thereby creating a safe working environment.

[0035] According to various embodiments, as shown in Figure 3(a), the protective member 7 is formed by plasma-treating the surface of the wooden board layer 21 and then applying a hard elastic layer 22. As an example, the plasma device (23) can move along the surface of the wooden board layer 21 while performing plasma treatment on the surface of the wooden board layer 21.

[0036] Plasma treatment can activate the surface molecules of the wood board layer 21, thereby improving the adhesion of the hard elastic layer 22 to the surface of the wood board layer 21. Improved adhesion of the hard elastic layer 22 can further enhance the rigidity of the protective member 7, minimizing the amount and number of coats required for the hard elastic layer 22, thus improving cost-effectiveness.

[0037] According to various embodiments, the protective member 7 is superimposed on the rigid elastic layer 22 and further includes an auxiliary coating layer 24 containing at least one material from polyurethane, PVC, epoxy, and silicone. At least one of polyurethane, PVC, epoxy, and silicone has the advantage of being less expensive than polyurea, but has the disadvantage of being less effective in improving the rigidity of the wood board layer 21 compared to polyurea. Therefore, it is preferable to apply the auxiliary coating layer 24 together with the rigid elastic layer 22 rather than applying the auxiliary coating layer 24 alone to strengthen the rigidity of the wood board layer 21. For example, as shown in Figure 3(b), the auxiliary coating layer 24 can be applied to the surface of the wood board layer 21 first, and then the rigid elastic layer 22 can be applied on top of the auxiliary coating layer 24, or as shown in Figure 3(c), the rigid elastic layer 22 can be applied to the surface of the wood board layer 21 first, and then the auxiliary coating layer 24 can be applied on top of the rigid elastic layer 22.

[0038] Thus, by using the lower-cost auxiliary coating layer 24 together with the rigid elastic layer 22, it is possible to minimize the amount and number of coats of the expensive rigid elastic layer 22 while ensuring the rigidity of the protective member 7, thereby improving cost efficiency.

[0039] According to various embodiments, when both the rigid elastic layer 22 and the auxiliary coating layer 24 are applied, either the rigid elastic layer 22 or the auxiliary coating layer 24 is applied partially to one surface of the wooden board layer 21 in a grid-like or scattered dot pattern.

[0040] According to this, while ensuring the rigidity of the protective member 7, the amount and number of applications of the expensive hard elastic layer 22 can be further minimized, thereby further improving cost efficiency.

[0041] According to various embodiments, the wood board layer 21 includes medium-density fiberboard (MDF). While general plywood is manufactured by stacking multiple layers of wood and gluing them together, resulting in air between the layers, medium-density fiberboard (MDF) is manufactured by crushing wood and then compressing it with adhesive resin, in which case the air is removed.

[0042] Therefore, medium-density fiberboard (MDF) has uniform surface characteristics with higher rigidity and density compared to general plywood. In particular, its uniform surface characteristics result in excellent coating quality for the hard elastic layer 22.

[0043] According to various embodiments, the protective member 7 may include a guide member 26 provided along the outer edge of the wooden board layer 21. The guide member 26 may be made of a metallic material such as iron (Fe) or aluminum (Al), but is not limited to these, and may also be made of a synthetic resin such as plastic. The guide member 26 not only protects the outer edge of the wooden board layer 21 but also complements the rigidity of the protective member 7. On the other hand, the protective member 7 may be fixedly connected to the frame 6 with fixing members 25 such as bolts.

[0044] According to various embodiments, an auxiliary protective member 8 can also be provided on the outer side wall portion 12 of the frame 6. The auxiliary protective member 8 can also be provided in a configuration similar to that of the protective member 7. For example, the auxiliary protective member 8 may also have a wooden board layer 21 fixedly provided to cover at least a part of the outer side wall portion 12, and a hard elastic layer 22 applied to one surface of the wooden board layer 21. Further explanation of the configuration of the auxiliary protective member 8 will be omitted as it will overlap with the previous explanation. Of course, the auxiliary protective member 8 can also have a configuration different from that of the protective member 7.

[0045] According to various embodiments, the scaffolding module 2 may be provided with a wire fastening ring 38 on which a wire 39 is attached. The wire 39 may include rubber bands, ropes, etc. The wire fastening ring 38 may be placed on the wire 3. The wire 39 can securely fasten or connect not only adjacent scaffolding modules 2 but also spaced-apart scaffolding modules 2, improving the bonding strength between them.

[0046] Therefore, using the wire 39 and the wire fastening ring 38 can improve the overall safety of the scaffolding system 1.

[0047] Figure 4 shows an example of a corner module 30 installed and connected between a pair of scaffolding modules 2 in Figure 1. While multiple corner modules 30 may be provided depending on the configuration of the scaffolding system 1, for the sake of explanation, we will assume below that the corner module 30 is installed and connected between a first scaffolding module 31 and a second scaffolding module 32. That is, the corner module 30 is installed and connected between the first scaffolding module 31 and the second scaffolding module 32, which are positioned intersecting at their horizontal edges.

[0048] The corner module 30 includes a plurality of vertical columns 33 forming a side wall, a safety bar 34 installed horizontally between a pair of vertical columns 33, and a U-shaped body with an opening, provided on each of the opposing faces of the pair of vertical columns 33, to which both ends of the safety bar 34 are detachably fixed through the opening. As an example, if the corner module 30 has four faces, the safety bar 34 is not attached to the safety bar attachment part 35 on the two faces 37 connected to the first scaffolding module 31 and the second scaffolding module 32. This allows workers to move freely between the pair of storage spaces S, as the storage spaces S of the first scaffolding module 31 and the second scaffolding module 32 are interconnected. On the other hand, the safety bar 34 can be attached to the safety bar attachment part 35 on the remaining two faces to guide workers moving between the pair of storage spaces S not to exit through the two faces not connected to the first scaffolding module 31 and the second scaffolding module 32.

[0049] By using the safety bar 34 and the safety bar attachment / detachment part 35 in this way, the storage spaces S of the first scaffolding module 31 and the second scaffolding module 32 can be easily connected regardless of the installation direction of the corner module 30 relative to the first scaffolding module 31 and the second scaffolding module 32, thereby improving cost efficiency and improving safety by guiding workers moving through the storage spaces S of the first scaffolding module 31 and the second scaffolding module 32 not to exit through sides that are not connected to the first scaffolding module 31 and the second scaffolding module 32.

[0050] According to various embodiments, in Figure 4, the opening of the safety bar attachment / detachment section 35 is formed in the Z-axis direction. However, if the direction of the opening is slightly inclined inward from the corner module 30, it becomes easier to prevent workers from attempting to exit in a direction not connected to the first scaffolding module 31 and the second scaffolding module 32.

[0051] Figure 5 shows an example of the stacking storage section 44 and stacking ring section 45 provided in the scaffolding module 2 of Figure 1. For the sake of explanation, the third scaffolding module 41 and the fourth scaffolding module 42, which are stacked vertically, will be used as examples below, but it should be noted that the following explanation is not limited to the third scaffolding module 41 and the fourth scaffolding module 42.

[0052] When the wire members 3 of the third scaffolding module 41 and the fourth scaffolding module 42 are provided as tubular bodies, the frame 6 of the upper third scaffolding module 41 has a stacking storage section 44 at the end of the tubular body, and the frame 6 of the lower fourth scaffolding module 42 protrudes to be accommodated in the stacking storage section 44 and has a stacking ring section 45 that has a ring shape that narrows in width along the protruding direction. The stacking ring section 45 can be used when transporting the fourth scaffolding module 42 and can also be used when stacking the third scaffolding module 41 on the fourth scaffolding module 42. In particular, because the stacking ring section 45 has a ring shape that narrows in width along the protruding direction, the stacking ring section 45 can be easily accommodated in the stacking storage section 44 when stacking the third scaffolding module 41 on the fourth scaffolding module 42, and the gap between the stacking ring section 45 and the stacking storage section 44 can be minimized when fully accommodated.

[0053] Thus, the ring shape of the stacking ring portion 45 facilitates stacking between scaffolding modules 2 and can improve stacking stability. Furthermore, since the stacking ring portion 45 performs all the functions of transporting and stacking the scaffolding modules 2, it can improve cost efficiency compared to providing separate configurations for each function.

[0054] Figure 6 shows an example of a soundproofing panel 53 installed on the upper edge of frame 6 in Figure 1.

[0055] As shown in Figure 6, the scaffolding system 1 includes soundproofing panels 53 that are plate-shaped and installed along the top edge of the frame 6, and are inclined at a predetermined angle. The soundproofing panels 53 may be installed on only some of the frames 6, and the inclination angle may be adjusted by the design method. The soundproofing panels 53 may also be installed on the top edge of the frame 6 via a separate frame.

[0056] Having a soundproofing panel 53 in this way can reduce the damage to the surrounding area caused by noise from building demolition work.

[0057] Although the present invention has been described in detail through preferred embodiments above, the present invention is not limited thereto and can be implemented in various ways within the scope of the claims.
