Description

Technical Field

[0001] The present invention belongs to the technical field of roofs for prefabricated scaffolding, and more particularly relates to a roof for prefabricated scaffolding which is installed to improve workability and safety of temporary construction scaffolding during rainfall or snowfall.

Background Art

[0002] In work on prefabricated scaffolding at construction sites, during rainfall or snowfall, although it is desired to minimize exposure to moisture for operations such as painting and waterproofing work, no roof, eave or the like is provided at the topmost part of the scaffolding, which results in situations where work cannot be performed or has to be suspended. Furthermore, in work using power tools, hand tools and the like, workers either take temporary emergency measures such as simply covering the area with vinyl sheeting, or are forced to work while being exposed to rainfall or snowfall. Moreover, hands become slippery, and there is also concern over risks such as falling tools caused by decreased body temperature. In addition, when cloth plates on the walking surface of the scaffolding get wet, the risk of falling accidents from the scaffolding further increases. For these reasons, work efficiency inevitably decreases, and it is said that labor costs tend to increase 3 to 4 times during rainfall compared to clear weather, which is a major cause of delays in work schedules. In this regard, to improve work efficiency in rainy weather, there is a generally used method of providing a frame at the topmost step of the scaffolding and installing a temporary roof using plywood panels, sheet metal or the like. For example, the following Patent Document 1 discloses a roof curing frame for external scaffolding characterized by comprising: a substantially T-shaped first frame composed of a vertical member connectable to the upper end of a vertical frame at the topmost step of the scaffolding and a roof member attached to the upper end of the vertical member; and a substantially L-shaped second frame composed of a vertical member connectable to the upper end of a vertical frame at the topmost step of the scaffolding and a roof member attached to the upper end of the vertical member, wherein the roof members of the first frame and the second frame are mutually connected to form a series of roof frames (see Claim 1 of Patent Document 1).

Patent Document 1

[0004] However, the roof protection frame for external scaffolding described in Patent Document 1 is often avoided because it has a large, complex structure that is difficult to handle, and the installation costs are high. Although other products such as "temporary roofs" for scaffolding are also sold, their widespread adoption has not progressed because the labor costs involved in installation, management during the installation period, and removal are significantly increased. In addition, as a simple protective measure, it is sometimes seen in snowy areas to attach plastic sheets or agricultural poly sheets to the top of scaffolding using duct tape or similar adhesive. However, this method has potential drawbacks such as being "vulnerable to wind," "prone to puddles," "unable to withstand the weight of water," and "leaving tape residue in high temperatures during the summer." Currently, none of these methods can be considered sufficient protection against rain, and these are issues that need to be addressed.

[0005] Therefore, the object of the present invention is to provide a roof structure for a frame scaffold that is easy to install, has excellent constructability, and is economical, while improving the workability and safety of temporary scaffolding for construction during rainfall and snowfall when constructing buildings.

[0017] A preferred embodiment of the roof structure of the scaffolding frame of the present invention will be described below with reference to the drawings. This roof structure is used when constructing building 1 at a construction site as shown in Figure 6. In a frame scaffolding 2 assembled with frame 20 having pocket sections 21, there is no scaffolding at the top 22 of the frame scaffolding 2, and it is not possible to protect from rain or snow there. Therefore, it is installed at the top 22 of the frame scaffolding 2 to protect from rain and snow.

[0018] The basic structure of the roof body in this embodiment consists of a horizontal projection 3, a vertical upright section 4, and a sheet attachment section 5, all integrally formed from steel pipes with a diameter of φ=48.6 mm or 42.7 mm. However, although not shown in the figures, these horizontal projection 3, vertical upright section 4, and sheet attachment section 5 may be made of separate components. The horizontal projection 3 is approximately 200 mm long and extends horizontally toward the opposite side from building 1. The vertical upright portion 4 extends from the outer end 32 of the horizontal projection portion 3, bending upward vertically by approximately 200 mm and maintaining an upright position. From its upper end 40, a sheet attachment portion 5 is continuously formed, bending and extending in the direction of the building 1 under construction. The length of the sheet attachment portion 5 is approximately 1100 mm. However, the lengths of the horizontal protrusion 3, the vertical upright portion 4, and the seat mounting portion 5 are not limited to the lengths described above.

[0019] An insertion portion 31 is provided at the base end 30 of the horizontal projection portion 3. This utilizes the pocket portions 21 that are normally provided in multiples on the scaffolding frame 20 as a means of fixing the roof body to the scaffolding frame 20 (Figures 2 to 4, Figure 6), and is formed to protrude downward with a size that allows it to be freely inserted into the pocket portion 21. Specifically, the pocket portion 21 is formed to be 40 mm high, 40 mm wide, and 20 mm deep, while the insertion portion 31 is formed to be 65 mm high, 30 mm wide, with a depth of 16 mm at the lower end, gradually increasing upwards, and a depth of 20 mm at the upper end. The insertion portion 31 may have a cross-section that penetrates vertically, such as a U-shape, a wedge shape, or an oval shape, as shown in the illustrated example, and its length is not limited to the above, as long as it is large enough to be inserted into the pocket portion 21. As shown in Figures 2 and 3, the insertion portion 31 of this embodiment is positioned perpendicular to the building 1 (not shown) located to the left (Figure 6). However, as shown in Figure 4, the horizontal projection 3' may be rotated 90° relative to the building 1 (not shown) located to the left and positioned parallel to the building 1, and then inserted into the pocket portion 21 of the building frame 20.

[0020] Furthermore, as shown in Figure 5, an embodiment in which a reinforcing bar 7 supported by a connecting bar 70 is attached to the lower end of the horizontal projection 3 is also suitably adopted. The length of the reinforcing bar 7 is set so that when the insertion portion 31 of the horizontal projection 3 is inserted into the pocket portion 21 of the frame 20, the tip 71 of the reinforcing bar 7 abuts against the frame 20. Furthermore, the tip of the reinforcing bar 7 is formed into a Y-shaped fitting portion 72 so that it fits into and abuts against the frame 20. However, the fitting portion 72 is not limited to such a Y-shape, and may be formed into a U-shape or a U-shape, for example, which are not shown in the illustration.

[0021] As shown in Figure 6, the sheet mounting section 5 is formed in a sloping state that gradually rises toward the building 1 in order to allow rainwater to escape from the building 1. However, in consideration of adjacent houses, it is also possible to form it in a sloping state that gradually rises toward the opposite direction from the building 1, or to form it in a horizontal state without slope. Furthermore, the tip 50 of the sheet mounting portion 5 has a locking hole 51 formed therein, which allows the strings 60 of the roof sheet 6 to be secured. Furthermore, multiple protrusions 52, which can be used to lock the connecting member 8 (described later), are attached to the upper or outer surface of the sheet mounting section 5 in pairs at short intervals (see Figure 7).

[0022] Multiple of the aforementioned roof sections are connected to the scaffolding frame 20. At this time, by striking the upper part of the horizontal projection 3 near the base end 30 with a hammer or the like, the insertion section 31 can be easily inserted and fixed into the pocket section 21 located at the top of the scaffolding frame 20 (Figures 1 and 2). Then, the roof sheet 6 is covered over the sheet mounting section 5 which is positioned facing the building 1. Note that in Figure 6, the illustration of the roof section installed continuously in the upper right is omitted.

[0023] When covering the roof sheet 6, the bridging member 8 is preferably used. As partially omitted in Figure 7, this connecting member 8 has an elastic body such as a spring installed inside the pipe body so that its length can be adjusted freely, and both ends are provided with claw-shaped hooks 80 that are open downwards. Therefore, the connecting member 8 can be easily attached to the sheet mounting section 5 by locking the hooks 80 at both ends of the connecting member 8 between the multiple protrusions 52, 52 attached to the sheet mounting section 5 as described above.

[0024] Therefore, the insertion part 31 of the roof body, with the sheet attachment part 5 facing the building 1, is inserted and fixed into the pocket 21 at the uppermost position of the outer frame 20 located at the top 22 of the scaffolding 2 (Figure 2). The fixing work of the desired number of insertion parts 31 of the roof body is carried out over the required area of ​​the building 1 under construction. After that, the desired number of bridging members 8 are placed between adjacent sheet attachment parts 5, the roof sheet 6 is placed over the sheet attachment parts 5, and the strings 60 on the left and right sides of the roof sheet 6 are passed through the locking holes 51 provided at the tip 50 of the sheet attachment part 5 and tied to fix it, thereby completing the installation of the roof body (Figure 6). Thus, even if it rains or snows while working at the top 22 of the scaffolding 2, the roof sheet 6 provides protection, allowing for safe work.

[0025] Although embodiments have been described above based on the drawings, it should be noted that the present invention is not limited to the illustrated examples and includes design modifications and variations in application that are commonly performed by those skilled in the art, without departing from the technical idea.
