Description

Technical Field

[0001] The present invention belongs to the technical field of the roof body of a framework scaffold, and more specifically, relates to the roof body of a framework scaffold installed to improve the workability and safety of a temporary construction scaffold during rainfall or snowfall.

Background Art

[0002] In the work on a framework scaffold at a construction site, during rainfall or snowfall, although it is desired to avoid moisture as much as possible in painting work, waterproof work, etc., since there is no roof, eaves, etc. provided at the top of the scaffold, the work cannot be carried out or has to be suspended. Also, in work using power tools, tools, etc., a temporary measure such as simply covering with vinyl is taken, or the work has to be carried out while being exposed to rainfall or snowfall. Moreover, there are concerns about the risk of tool dropping due to slippery hands and a decrease in body temperature. In addition, the risk of slipping accidents from the scaffold is further increased due to the wetting of the plank on the walking surface of the scaffold. For such reasons, the work efficiency inevitably decreases, and it is said that the labor cost increases by 3 to 4 times during rainfall compared to sunny days, which is a major cause of delays in the work plan. In this regard, to improve the work efficiency in rainy weather, there is a method of generally providing a framework at the uppermost stage of the scaffold and installing a temporary roof using plywood, sheet metal, etc. For example, in Patent Document 1 below, a substantially T-shaped first frame composed of a vertical member connectable to the upper end of the building site frame at the uppermost stage of the scaffold and a roof member attached to the upper end of this vertical member, and a substantially L-shaped second frame composed of a vertical member connectable to the upper end of the building site frame at the uppermost stage of the scaffold and a roof member attached to the upper end of this vertical member are provided, and the roof members of the first frame and the second frame are connected to each other to form a series of roof frames. An external scaffold roof curing frame is disclosed (see Claim 1 of the same 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. [Means for solving the problem]

[0007] Claim 2 The invention described above is a roof body for a frame scaffolding as described in claim 1, characterized in that the connecting member 3 is provided on the vertical upright portion 4 so as to be positioned vertically or horizontally with respect to the building 1. [Effects of the Invention]

[0008] According to the present invention, the roof structure of the scaffolding frame, with its simple vertical upright section, sheet attachment section, and roof sheet, can be easily and reliably installed on the top of the scaffolding frame assembled with scaffolding frames, offering excellent workability and cost-effectiveness.

Best Mode for Carrying Out the Invention

[0014] A preferred embodiment of the roof body of the framework scaffold of the present invention will be described below with reference to the drawings. When building the building 1 at the construction site as shown in FIG. 4, in the framework scaffold 2 assembled with the building frame 20, there is no scaffold at the uppermost part 22, and rain and snow cannot be avoided. Therefore, it is installed at the uppermost part 22 of the framework scaffold 2 and is used for the purpose of avoiding rain and the like.

[0015] The basic structure of the roof body of this embodiment is composed of a vertical upright portion 4 and a sheet attachment portion 5 integrally formed by steel pipes made of single pipes with φ = 48.6 mm or 42.7 mm. However, although not shown, the vertical upright portion 4 and the sheet attachment portion 5 may be constituted by separate members. The vertical upright portion 4 stands upright and extends 800 mm in the vertical direction, and a sheet attachment portion 5 that is bent and extended in the direction of the building 1 under construction from its upper end 40 is continuously formed. The length of the sheet attachment portion 5 is preferably 900 mm. However, the vertical upright portion 4 is not limited to the above length and can be implemented with a length in the range of 1000 to 100 mm, and the sheet attachment portion 5 is not limited to the above length and can be implemented with a length in the range of 2000 to 100 mm.

[0016] The vertical upright portion 4 is provided with a connecting member 3 that can be connected to the building frame 20 of the framework scaffold 2. As the connecting member 3, a single-pipe clamp of a fastening fitting that can be connected to a steel pipe is preferably used (see FIG. 3). This connecting member 3, which is a single-pipe clamp, has a short neck portion 30 welded and fixed to the vertical upright member 4, and is a half-divided fitting that can be rotated at the tip of the neck portion 30 and can be opened. After surrounding the building frame 20 from the outside, it is configured to be fixable at a desired position of the building frame 20 by an attached bolt and nut (FIG. 4). As shown in Figures 1 and 4, the connecting member 3 is provided in a vertical arrangement facing the direction of the building 1 at two locations: the lower end of the vertical upright section 4 and a position above it (for example, 400 mm above the lower end). However, as shown in Figure 2, the connecting member 3 may also be fixed in a parallel arrangement rotated 90° relative to the building 1. In that case, the vertical upright section 4 will be located inside the building frame 20 (not shown).

[0017] As shown in Figure 4, 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 5).

[0018] With multiple of the aforementioned roof sections connected to the building frame 20 via connecting members 3, a roof sheet 6 is placed over the sheet mounting section 5, which is positioned facing the building 1. In Figure 4, the roof sections installed continuously in the upper right are not shown.

[0019] When covering the roof sheet 6, the bridging member 8 is preferably used. As partially omitted in Figure 5, 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 downward-facing claw-shaped hooking parts 80. 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.

[0020] Therefore, at the desired position on the outer frame 20 at the top 22 of the scaffolding 2, multiple connecting members 3 of the roof body are fixed with the sheet attachment section 5 facing the building 1 (Figure 3). The fixing work of the desired number of roof body connecting sections 3 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 sections 5, the roof sheet 6 is placed over the sheet attachment sections 5, and the strings 60 on the left and right of the roof sheet 6 are passed through the locking holes 51 provided at the tip 50 of the sheet attachment section 5 and tied to secure it, thereby completing the installation of the roof body (Figure 4). 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.

[0021] 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.
