Description

[Technical Field]

[0001] The present invention relates to the technical field of roof bodies for framework scaffolding, and more particularly to a roof body for framework scaffolding that is installed to ensure workability and safety of temporary scaffolding for construction during rain or snow. [Background technology]

[0002] When working on framework scaffolding at a construction site, when it rains or snows, it is often necessary to avoid moisture as much as possible for painting or waterproofing work, but because there is no roof or eaves at the top of the scaffolding, work cannot be carried out or must be stopped. Furthermore, when working with power tools or other tools, workers are forced to take emergency measures such as covering the tools with plastic or work in the rain or snow. Furthermore, there is a risk of tools being dropped due to slippery surfaces and a drop in body temperature. Additionally, the risk of slipping and falling from the scaffolding increases when the scaffolding's walking surface gets wet. For these reasons, work efficiency inevitably declines, and it is said that labor costs tend to increase by three to four times during rainy weather compared to sunny days, becoming a major cause of delays in work plans. In this regard, in order to improve work efficiency in rainy weather, a method is generally used in which a framework is provided on the top stage of scaffolding and a temporary roof is installed using plywood, sheet metal, etc. For example, Patent Document 1 listed below discloses a roof curing frame for external scaffolding, characterized in that it comprises a substantially T-shaped first frame made up of vertical members connectable to the upper ends of the site frame of the top stage of the scaffolding and a roof member attached to the upper ends of these vertical members, and a substantially L-shaped second frame made up of vertical members connectable to the upper ends of the site frame of the top stage of the scaffolding and a roof member attached to the upper ends of these vertical members, and the roof members of the first frame and the second frame are interconnected to form a continuous roof frame (see claim 1 in Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Application Publication No. 5-79193 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the roof curing frame for external scaffolding described in Patent Document 1 is a large-scale structure that is difficult to handle, and the installation costs are high, so it tends to be avoided. Although other commercial materials such as "temporary roofs" for scaffolding are also sold, they have not yet become widespread due to the significant increase in labor costs involved in installation, maintenance during the installation period, and removal. Additionally, in snowy areas, a simple protective measure is to attach vinyl sheeting or agricultural poly sheeting to the top of the scaffolding with packing tape, etc. However, there are potential drawbacks to this method, such as it being weak against wind, prone to puddles, unable to withstand the weight of water, and leaving tape residue in the summer heat, so none of these methods can be considered sufficient rain protection, and these are issues that need to be resolved.

[0005] Therefore, the object of the present invention is to provide a roof body for a frame scaffolding that is easy to install, has excellent workability, and is economical, and that improves the workability and safety of temporary scaffolding for construction during rain or snow when constructing a building. [Means for solving the problem]

[0006] As a means for solving the problem, the invention described in claim 1 is a roof body to be installed on the top 22 of a framework scaffolding 2 assembled with a building frame 20 when constructing a building 1, Vertical standing part 4 and seat mounting part 5 and a bridging member 8 and a roof sheet 6. , (a) The vertical standing portion 4 can be freely connected to the frame 20 of the framework scaffolding 2. There is a single pipe clamp Connecting member 3 multiple and extending vertically, The sheet mounting portion 5 extends from the upper end 40 of the vertical standing portion 4, bending toward the building 1, At the tip of the roof, a fastening hole 51 is formed to fasten the roof sheet 6, and the roof is formed to be gradually inclined higher toward the building 1. (b) The bridging member 8 is composed of a pipe body that reinforces the adjacent roof bodies and covers the roof sheet 6, while a plurality of protrusions 52 that can be freely engaged with the hook portions 80 provided on both ends of the bridging member 8 are attached to the upper surface or outer surface of the sheet mounting portion 5, and the bridging member 8 is engaged with the protrusions 52 and is hung across the adjacent sheet mounting portions 5 in the desired number; (c) Multiple The vertical standing portion 4 With the connection members 3 connected to the building frames 20, they are placed on the sheet mounting portions 5 facing the building 1. The aforementioned Roof sheet 6 is covered It becomes thing, This is a roof body of a frame scaffolding characterized by the above.

[0007] Claim 2 The invention described above is a roof body of a framework scaffolding described in claim 1, characterized in that the connecting member 3 is provided on the vertical standing part 4 so as to be arranged vertically or horizontally relative to the building 1. [Effects of the Invention]

[0008] The roof body of the frame scaffolding of the present invention has excellent workability and economy, as the simply constructed vertical standing section, sheet mounting section and roof sheet can be easily and securely installed at the top of the frame scaffolding assembled with a building frame.In addition, even if it rains or snows while working at the top, the roof sheet provides protection, improving workability and safety when using temporary construction scaffolding. [Brief explanation of the drawings]

[0009] [Figure 1] (A) is an overall view showing the roof body of the framework scaffolding of the present invention, and (B) is a plan view of (A).

[0010] [Figure 2] FIG. 10 is a plan view showing a different roof structure.

[0011] [Figure 3] 10 is an enlarged view showing the state in which the connecting member of the roof body is connected to the building frame. FIG.

[0012] [Figure 4] FIG. 2 is a perspective view showing the roof body in use with some parts omitted.

[0013] [Figure 5]10 is an explanatory diagram showing, with some parts omitted, a state in which a bridging member (the internal structure is also shown) is locked to a seat mounting portion. FIG. BEST MODE FOR CARRYING OUT THE INVENTION

[0014] A preferred embodiment of the roof body of the framework scaffolding of the present invention will be described below with reference to the drawings. This roof body is used when constructing a building 1 at a construction site such as that shown in Figure 4, because there is no scaffolding at the top 22 of a framework scaffolding 2 assembled from a building frame 20 and it is therefore not possible to protect against rain or snow, and so it is installed at the top 22 of the framework scaffolding 2 to protect against rain, etc.

[0015] The basic structure of the roof body of this embodiment is composed of a vertical standing portion 4 and a sheet mounting portion 5, which are integrally formed from a single steel pipe with a diameter of 48.6 mm or 42.7 mm. However, although not shown in the drawings, the vertical standing portion 4 and the sheet mounting portion 5 may also be made of separate members. The vertical standing portion 4 extends vertically for 800 mm, and from its upper end 40, a sheet mounting portion 5 is formed, bending and extending continuously in the direction of the building 1 under construction. The length of the sheet mounting portion 5 is preferably 900 mm. However, the vertical standing portion 4 is not limited to the above length, and can have a length in the range of 1000 to 100 mm, and the sheet mounting portion 5 is also not limited to the above length, and can have a length in the range of 2000 to 100 mm.

[0016] The vertical standing member 4 is equipped with a connecting member 3 that can be freely connected to the building frame 20 of the framework scaffolding 2. A single-pipe clamp, which is a fastening metal fitting that can be connected to a steel pipe, is preferably used as the connecting member 3 (see Figure 3). This single-pipe clamp connecting member 3 is a split metal fitting that has a short neck 30 welded to the vertical standing member 4 and is rotatably connected at the tip of the neck 30, and is configured so that after enclosing the building frame 20 from the outside, it can be freely fixed at a desired position on the building frame 20 with the attached bolts and nuts (Figure 4). 1 and 4, the connecting members 3 are provided in two positions, at the bottom end of the vertical standing portion 4 and at a position above it (for example, 400 mm above the bottom end), in a vertical arrangement facing the building 1. However, as shown in Fig. 2, the connecting members 3 may also be fixed in a parallel arrangement with their orientation changed by 90° to the building 1. In that case, the vertical standing portion 4 will be disposed inside the building frame 20 (not shown).

[0017] As shown in Figure 4, the sheet mounting portion 5 is formed in an inclined state that gradually rises toward the building 1 so as to allow rainwater to escape outside the building 1. However, in consideration of neighboring houses, it is also possible to form it in an inclined state that gradually rises in the direction opposite to the building 1, or to form it in a horizontal state without an inclination. Further, at the tip 50 of this sheet attachment portion 5, a locking hole 51 is formed, in which a hole is provided to allow the string 60 of the roof sheet 6 to be locked. Furthermore, on the upper surface or outer surface of this seat attachment portion 5, a plurality of pairs of protrusions 52 are attached at close intervals (see FIG. 5) to which a bridging member 8, which will be described later, can be engaged.

[0018] With the above-mentioned roof bodies each connected to the building frame 20 via the connecting members 3, a roof sheet 6 is placed over the sheet mounting parts 5 arranged facing the building 1. In Fig. 4, the roof body installed continuously on the upper right is not shown.

[0019] When covering the roof sheet 6, a bridging member 8 is preferably used. As shown in Figure 5 with some parts omitted, this bridge member 8 is configured so that an elastic body such as a spring is loaded inside the pipe body, allowing the length to be freely adjusted, and both ends are provided with claw-shaped hook portions 80 that open downward. Therefore, the bridging member 8 can be easily attached to the seat mounting portion 5 by clamping and engaging the hook portions 80 at both ends of the bridging member 8 between the multiple protrusions 52, 52 attached to the above-mentioned seat mounting portion 5.

[0020] Therefore, multiple connection members 3 of the roof body are fixed at the desired position on the outer building frame 20 at the top 22 of the frame scaffolding 2, with the sheet mounting parts 5 facing the building 1 (Fig. 3). The desired number of connection parts 3 of the roof body are fixed over the required area of ​​the building 1 under construction. After that, the desired number of bridging members 8 are hung between adjacent sheet mounting parts 5, and the roof sheet 6 is placed over the sheet mounting parts 5. The left and right strings 60 of the roof sheet 6 are passed through locking holes 51 provided at the ends 50 of the sheet mounting parts 5 and tied to secure them, thereby completing the installation of the roof body (Fig. 4). Thus, when working at the top 22 of the framework scaffolding 2, even if it rains or snows, the roof sheet 6 protects the worker and the work can be done safely.

[0021] Although the 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 the range of design modifications and application variations that would normally be made by a person skilled in the art, provided that they do not deviate from the technical concept of the present invention.
