Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a safety fence for roof construction used in roof construction of buildings such as general houses.

[0002]

[Prior art]

 Generally, in roofing work, especially installation work of roofing materials such as roof tiles and galvanized iron, safety fences are installed to prevent people from falling or to prevent roofing materials from falling. As a safety fence in conventional roof construction, scaffolding pipes assembled from round pipes are used, and nets are suspended on the scaffolding pipes.

[0003]

[Problems to be solved by the device]

 With conventional scaffolding pipes assembled from round pipes to suspend nets for safety fences, the scaffolding pipes cannot be dismantled until the roof construction is completed, so long-term construction work is not possible. There is a concern that

Therefore, an object of the present invention is to provide a safety fence for roof construction that can be installed without using conventional scaffolding pipes.

[0005]

[Means for Solving the Problems]

 The present invention is directed to a mounting metal fitting that is externally fitted to an overhanging rod that is mounted by projecting on a building, a vertical hole provided in the mounting metal fitting, a pillar that is detachably erected in the vertical hole, and an upper portion of the pillar. It is a safety fence for roof construction that includes a net fastening part.

[0006]

[Action]

 With the above-described structure, the support rod is erected on the overhanging rod through the mounting metal fitting, and the net body is connected by the fastening portion.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a pillar of a building 2, to which a square pipe 3 for scaffolding, which overhangs and rods, is attached to the outside. At the base end of the square pipe 3 for scaffolding, a fixing device 4 for sandwiching the pillar 1 is provided. 1A is a roof. The fixing device 4 has a pair of support plates 5 and 6 projecting from the square pipe 3 for scaffolding, a screw rod 7 is screwed onto one of the support plates 5, and a pressing member 8 is attached to the tip of the screw rod 7. The handle 9 is provided at the other end. Further, a fitting 10 is provided at the tip of the scaffolding square pipe 3. The fitting 10 has a rectangular cross section, and the square pipe 3 for scaffolding can be slidably fitted onto the fitting 10.

A screw rod 11 is screwed through one side surface of the fitting 10, and a pressing member 12 is provided inside the screw rod 11 and a handle 13 is provided outside the screw rod 11. Further, a vertical hole 14 is provided on the other side surface of the mounting member 10 by fixing a square pipe 15. The pillar 16 attached to the vertical hole 14 is provided with a stopper 17 at its lower portion for engaging with the upper surface of the square pipe 15, and a top plate 18 wider than the square pipe 15 is horizontally fixed at the upper end. . At the center of the upper surface plate 18, hooks 20 and 21 as fastening portions for fastening the net 19 are provided. The hooks 20 and 21 are each cantilevered, and the tips 20A and 21A thereof are provided so as to be slightly above the top plate 18 so that the net 19 can be hooked. Further, the top plate 18 is provided with a receiving hole 23 into which the end of the handrail 22 is inserted. The handrail 22 has a pair of left and right pipes 24 and 25 inserted therein, and can be fixed with a tightening screw 26 at a predetermined length.

Numeral 27 is a mounting metal fitting provided at substantially the center of the square pipe 3 for scaffolding, which can be fixed by a screw rod (not shown) or the like similarly to the mounting metal fitting 10, and its upper surface. A hook 28 for locking the lower end of the net body 19 is provided on the.

Next, the operation of the above configuration will be described. First, the support plates 5 and 6 are arranged so as to be sandwiched between the pillars 1, and the holding member 8 is pressed against the pillars 1 by operating the handle 9 to fix the square pipe 3 for scaffolding. Then, the mounting metal fitting 10 that has been externally fitted in advance is placed at a predetermined position, and fixed by operating the handle 13. Similarly, fix the mounting bracket 27. After this, the columns 16 are inserted into the vertical holes 14 of the square pipes 15 to erect the columns 16. After arranging the plurality of columns 16 along the building 2 in this way, the upper part of the net 19 is hooked on the hooks 20 and 21, while the lower part of the net 19 is hooked on the hook 28 to be installed. . At this time, the net body 19 is installed in a concave shape. Further, both ends of the handrail 22 whose length has been adjusted are inserted into the receiving holes 23 to install the handrail 22. Therefore, even if a roof tile (not shown) or the like falls from the eaves during the installation work of the roof material, the roof tile 19 can receive the roof tile. Also, during roofing work, workers can safely move using the handrail 22.

As described above, in the above-described embodiment, the mounting metal fitting 10 is externally fitted and fixed to the scaffolding square pipe 3 which is mounted to project on the building 2, and the mounting metal fitting 10 has the vertical hole 14. A square pipe 15 is provided, a pillar 16 is detachably erected in the vertical hole 14, and hooks 20 and 21 for fixing a net body 19 to the upper portion of the pillar 16 are provided. You can easily install a safety fence without using it.

Further, since the hooks 20 and 21 are each cantilevered and are provided on the target, the mesh of the net body 19 can be securely hooked on both hooks 20 and 21 to ensure the net body. 19 can be connected.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications are possible, for example, the overhanging rod may be a section steel or the like instead of a pipe.

[0014]

[Effect of device]

 The present invention is directed to a mounting metal fitting that is externally fitted to an overhanging rod that is mounted by projecting on a building, a vertical hole provided in the mounting metal fitting, a pillar that is detachably erected in the vertical hole, and an upper portion of the pillar. By providing the net body provided with the fastening portion, it is possible to provide a safety fence for roof construction that can be installed without using conventional scaffolding pipes.
