[0002]

2. Description of the Related Art Safety measures for workers during construction on a roof are disclosed in Japanese Utility Model Publication No. 57-51549 and Japanese Utility Model Publication 4-198.

Japanese Utility Model Laid-Open No. 57-51549 discloses a support structure for a safety rope for ensuring the safety of a worker 1 who constructs a roof on a roof 10, as shown in FIG. .

This safety rope comprises a parent rope 22 hung along the ridge of the roof 10 and a safety belt 26 for the worker 1.
And a child rope 24 that connects the parent rope 22. In the conventional example shown in FIG. 7, both ends of the master rope 22 are connected to the master rope connecting plate 7.
It is supported by 0.

The master rope connecting plate 70 has a substrate 72 formed by bending a flat plate into a mountain shape. A hook ring 74 that connects the master rope 22 is provided on the bent top of the substrate 72.

The problem with FIG. 7 is that when the worker 1 finishes the work on the roof 10, the connecting plate 70 must be removed. However, in order to ensure the safety of the worker 1, safety cannot be ensured unless the connecting plate 70 is firmly fixed to the roof 10.

As described above, the work of removing the connection plate 70 which is firmly fixed is not only complicated but also the roof 10 may be damaged.

In this respect, the invention disclosed in Japanese Utility Model Publication No. 4-198 solves the above-mentioned problem and the structure thereof is shown in FIG.
As shown in.

The master rope connecting fitting 80 shown in FIG.

The feature is that the main rope connecting metal fittings are attached to the roof beams in advance.

According to the third aspect of the present invention, it is possible to take a safety measure by mounting the main rope immediately after the roof beam is attached to the building without attaching the main rope connecting fitting on the roof. .

A fourth aspect of the present invention is a method for constructing a roof using the roof ridge structure according to the first or second aspect, wherein a master rope is connected to the master rope connecting fitting before the joint purlin is attached. Then, the step of performing roof construction on the roof surface portion, and after the roof construction is completed except near the roof ridge top portion, the master rope is detached from the master rope connecting fitting, and the combined purlin is roofed. A step of embedding and fixing in the groove portion between the surface portions, and then performing a roof construction near the roof ridge top,
It is characterized by including.

According to claim 4, the construction work other than near the roof ridge top, including the work near the eaves, which is particularly dangerous in roof construction, can be performed while taking safety measures using the main rope. . Before construction work near the top of the roof ridge, the master rope is removed, the joint purlin is embedded and fixed, and the master rope connecting metal fitting is covered. Therefore, it is not necessary to take any special measures against rain leakage near the roof top.

According to a fifth aspect of the present invention, in the third or fourth aspect, the step of carrying in the roof beam to the site by using a crane by using the parent rope connecting metal member fixed in advance to the roof beam as a hanging tool. Is further included.

Conventionally, it was necessary to remove this kind of hanging tool later, but this hanging tool can be reused as a main rope connecting fitting,
Moreover, since it is finally covered by the connecting purlin, there is no need to separate it.
