Description

  The present invention relates to a fixing jig on a slate roof for installing a temporary work floor, a temporary passage, a temporary handrail, a temporary structure, or the like on a slate roof, and performing a work safely. The present invention relates to a fixing jig on a slate roof that fixes a temporary object to be installed so that it can be performed in a safe state when performing repair, painting, inspection, cleaning, and the like.

  In general, in a slate roof, the roof cross section arranged in the direction orthogonal to the roof slope is made into a structurally advantageous roof cross-sectional shape, so that it can withstand loads such as its own weight, snow, and wind. It is structured to transmit the load efficiently to the purlin. Therefore, the direction in which the roof flows (referred to as the longitudinal direction) and the direction of the base material (referred to as the main building) that supports the roofing material are provided orthogonal to each other. The direction in which the purlin flows is called the horizontal direction.

  In slate roof work, for example, repair of the roof itself, painting, etc., it is essential to take safety measures to prevent an operator's stepping accident. For example, although it is known to install a fall protection fence in the attic, it takes time for installation / removal work and increases the cost. In addition, it is necessary to walk while carefully checking the top of the main building, and the slate roof itself cannot be prevented and the operator's anxiety cannot be removed.

  Therefore, it is known to put a protective net on the roof (for example, Patent Document 1).

  In the device disclosed in Patent Document 1, the net interferes with work, and the work of the net portion cannot be performed. In addition, when an operator walks on the net, he / she has to walk while looking for the top of the main building, and the workability is poor.

As a technique that can be stepped on without being on the main building, it is known to build a scaffold on the roof (for example, Patent Document 2).
JP 2003-232100 A JP 2003-013573 A

  Although what is shown in patent document 2 is a reliable method, the installation of the fixing jig for constructing a scaffold is large and time-consuming and has the disadvantage of increasing costs. In particular, it is necessary to install a long steel pipe, which is a fixing jig, on the slate roof with a length straddling between the main building and the main building, which is heavy and heavy. In addition, since the slate roof and the steel pipe are in line contact, it is necessary to make the steel pipe strong in view of the safety of the worker, and it must be heavy.

  An object of the present invention is to provide a fixing jig that is light in weight, can be securely held on a slate roof, and can be safely operated.

  In the present invention, paying attention to the structure of the purlin, in particular, using a mounting member that attaches a slate roof to the purlin, a base member that engages with the mounting member is provided, and legs are provided on both sides of the base member.

The fifth embodiment is effective when setting the temporary handrail 40 and the like in the same direction as the purlin 8. In addition, a part of upper end part of the 1st vertical plate member 113 and the 2nd vertical plate member 114 is cut, and it is lightening. Even in the first embodiment, a portion having no influence may be cut to reduce the weight as in the fifth embodiment.

(Embodiment 6)
The sixth embodiment will be described with reference to FIG. In the sixth embodiment, the height is lowered as in the fourth embodiment with respect to the fifth embodiment, and detailed description thereof is omitted. Only parts different from the fourth embodiment will be described, and detailed description will be omitted. The sixth embodiment is a type in which the temporary handrail 40 is assembled in the same direction as the main building 8 with respect to the fourth embodiment, with the direction of the clamp portion 20 being rotated by 90 °. Note that there are two clamp portions 20.

(Embodiment 7)
Embodiment 7 is demonstrated based on FIG.15 and FIG.16. Only the parts different from the first embodiment will be described, and the description of the same parts will be omitted. In this Embodiment 7, the clamp part 230 is attached to the 1st vertical board member 13 and the 2nd vertical board member 14 by the base 25 so that rotation is possible. Accordingly, the fixing member 230 can be freely changed not only in a direction parallel to the main building 8 or perpendicular to the main building 8 but also in a direction inclined with respect to the main building 8, so that work on the slate roof 1 or on the slate roof 1 can be performed. Depending on the structure and the like, the temporary handrail 40 can be provided in an optimal direction and configuration.

(Embodiment 8)
Embodiment 8 will be described with reference to FIG. Only the parts different from the first embodiment will be described, and the description of the same parts will be omitted. In the eighth embodiment, instead of the pipe member 16, a semi-cylindrical body 416 in which the pipe member is halved is used as the leg portion. Then, the lower end portion of the first vertical plate member 413 is joined into the semi-cylindrical body 416. A second vertical plate member 412 is provided between the two first vertical plate members 413, and a third vertical plate member 414 is provided outside the two first vertical plate members 413.
