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]

[0007] The invention described in claim 2 is a roof body of a framework scaffolding described in claim 1, characterized in that the insertion portion 31 is provided on the horizontal protrusion portion 3 so as to be positioned vertically or horizontally relative to the building 1.

[0008] Claim 3 The invention described in (1) is such that a reinforcing bar 7 supported by a connecting bar 70 is attached to the lower end of the horizontal protrusion 3, and the length of the reinforcing bar 7 is set so that when the insertion portion 31 of the horizontal protrusion 3 is inserted into the pocket portion 21 of the building frame 20, the tip 71 of the reinforcing bar 7 abuts against the building frame 20, and, The tip of the reinforcing bar 7 attached to the horizontal protrusion 3 is formed into a Y-shaped, U-shaped, or C-shaped fitting portion 72 so as to fit into and abut against the building frame 20. The roof body of the framework scaffolding described in claim 1 or 2 is characterized by the above. [Effects of the Invention]

[0009] According to the roof body of the frame scaffolding of the present invention, the horizontal protrusion has an insertion portion at its base that can be freely inserted into a pocket portion of the building frame and extends toward the opposite side of the building, the vertical upright portion extends from the outer end of the horizontal protrusion and bends upward, and the sheet mounting portion extends from the upper end of the vertical upright portion and bends toward the building, and with the insertion portions of the horizontal protrusions of the multiple roof bodies respectively inserted into the desired number of pocket portions of the building frame, a roof sheet is covered over the sheet mounting portions arranged toward the building.This means that when constructing a building, improved workability and safety of temporary construction scaffolding is achieved during rain and snow, and an economical roof body that is easy to install and has excellent workability is realized.

[0017] 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 6, where a framework scaffolding 2 is assembled using a building frame 20 having a pocket portion 21, and there is no scaffolding at the top 22 of the framework scaffolding 2, making it impossible to protect against rain and snow, so it is installed at the top 22 of the framework scaffolding 2 to protect against rain, etc.

[0018] The basic structure of the roof body of this embodiment is composed of a horizontal protrusion 3, a vertical rising 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 horizontal protrusion 3, the vertical rising portion 4, and the sheet mounting portion 5 may also be composed of separate members. The horizontal protrusion 3 is approximately 200 mm long and extends horizontally toward the opposite side from the building 1. The vertical standing portion 4 continues from the outer end 32 of the horizontal protrusion 3, bends vertically upward for about 200 mm, and extends while maintaining an upright state, and from its upper end 40, a sheet mounting portion 5 is formed continuously, bending and extending further in the direction of the building 1 under construction. The length of the sheet mounting portion 5 is about 1100 mm. However, the lengths of the horizontal protrusion 3, the vertical rising portion 4, and the seat attachment portion 5 are not limited to the above lengths.

[0019] An insertion portion 31 is provided at the base end 30 of the horizontal protrusion 3. This is a means for fixing the roof body to the building frame 20 by utilizing the pocket portions 21 that are usually provided in multiple locations on the building frame 20 (Figs. 2 to 4, 6), and is formed to protrude downward with a size that allows it to be freely inserted into the pocket portions 21. That is, the pocket portions 21 are 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, and 16 mm deep at the bottom, gradually increasing upward until it reaches a depth of 20 mm at the top. The cross section of this insertion portion 31 that penetrates vertically may be U-shaped as shown in the example, or may be wedge-shaped, oval, etc., and the length is not limited to the above, as long as it is large enough to be inserted into the pocket portion 21. 2 and 3, the insertion portion 31 of this embodiment is provided facing the building 1 (not shown) located on the left and disposed perpendicular to the building 1 (FIG. 6). However, like the horizontal protrusion 3' shown in FIG. 4, it may be provided so as to be turned 90 degrees relative to the building 1 (not shown) located on the left and disposed parallel to the building 1, and inserted into the pocket portion 21 of the building frame 20.

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

[0021] As shown in Fig. 6, 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 to the outside of the building 1. However, in consideration of neighboring houses, it is also possible to form the sheet mounting portion 5 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. 7) to which a bridging member 8, which will be described later, can be engaged.

[0022] A plurality of the above-described roof bodies are connected to the building frame 20. At this time, by hitting the upper part of the horizontal protrusion 3 near the base end 30 with a hammer or the like, the insertion part 31 can be easily inserted into the pocket part 21 located at the top of the building frame 20 and fixed (Figs. 1 and 2). Then, the roof sheet 6 is covered on the sheet mounting part 5 arranged facing the building 1. Note that in Fig. 6, the roof body installed continuously on the upper right is not shown.

[0023] When covering the roof sheet 6, a bridging member 8 is preferably used. As shown in Figure 7 with some parts omitted, this bridging 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.

[0024] Therefore, the insertion portions 31 of the roof body, with the sheet mounting portions 5 facing the building 1, are inserted and fixed into the highest pockets 21 of the outer building frame 20 at the top 22 of the frame scaffolding 2 (Fig. 2). The desired number of insertion portions 31 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 portions 5, and the roof sheet 6 is placed over the sheet mounting portions 5. The strings 60 on the left and right sides of the roof sheet 6 are passed through locking holes 51 provided at the ends 50 of the sheet mounting portions 5 and tied to secure them, thereby completing the installation of the roof body (Fig. 6). 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.

[0025] 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.
