BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a safety rope for preventing a worker from falling down during construction on a roof and a construction method using the same.

[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 No. 4-198.

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

[0004] The safety rope is provided with a master rope 22 hung along the top of the roof 10 and a safety belt 26 of the worker 1.
And a child rope 24 connecting the parent rope 22. In the conventional example shown in FIG. 8, both ends of the master rope 22 are connected to the master rope connecting plate 7.
0 supported.

[0005] The master connecting plate 70 has a substrate 72 formed by bending a flat plate into a mountain shape. A hanging ring 74 for connecting the master rope 22 is provided at the bent top of the substrate 72.

[0008] The problem shown in FIG. 8 is that when the worker 1 finishes working on the roof 10, the connecting plate 70 must be removed. However, in order to ensure the safety of the worker 1, the work of removing the connecting plate 70 is not only very complicated but also may damage the roof 10.

In this respect, the device 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 FIG.

[0008] The parent metal fixture 80 shown in FIG.

A guide cylinder 86 through which the screw rod 82 can be inserted is provided so that the ring 82a of the screw rod 82 can be disposed at a position protruding above the roof finishing material 88.

According to the conventional example shown in FIG. 9, the screw rod 82 can be easily detached from the nut support plate 84 after the construction of the roof is completed. Further, if the screw rod 82 is attached again for roof repair or the like, safety at the time of the repair work can be ensured.

[0011]

The first problem with the prior art shown in FIG. 9 is that the number of members is large and the structure is complicated. 86 and a nut support plate 84.

[0012] Since the parent metal fixture 80 is originally required only at the time of work and is not used at all when the work is completed, there is a strong demand for reducing the number of members and reducing costs.

The second problem is that the screw rod 82 is detached from the guide cylinder 86 after the construction is completed, and a cap is attached to the upper end of the guide cylinder 86. Since the tube 86 protrudes, it is very difficult to take measures against rain leakage. In particular, only a certain portion of the fixing bracket 80 for the main rope must be provided with a special countermeasure against rain leakage, which complicates the operation.

The conventional example shown in FIG. 8 has a structural problem. That is, the problem in the Japanese Utility Model Application Laid-Open No. 57-51549, which has not been solved by the invention disclosed in Japanese Utility Model Application Publication No. 4-198, is as follows.

According to the first aspect of the present invention, the number of members used for connecting the master rope is only two, that is, the master rope connecting portion and the bracket for the parent rope. Then, before the combined purlin is attached, the main rope can be hooked on the main rope connecting portion fixed to the main rope fixing bracket, and the roof can be constructed while taking safety measures. Furthermore, by removing the parent rope connecting part from the parent rope fixing bracket, the parent rope fixing bracket attached to the roof surface can be completely covered with the ridge without being exposed, and the surface is the same as before. Therefore, it is not necessary to take any special measures against rain leakage.

[0021] In addition, since the main bracket fixing part can be detachably attached to the flat part of the main rope fixing bracket, the height of the main rope fixing bracket itself can be made sufficiently small. It can be of a compact size that can be completely covered.

Further, since the anchorage for the parent rope is arranged in the area where the joint purlin is not arranged, the flat portion and the top of the joint purlin do not interfere with each other.

Further, since a flat plate and an inclined portion are formed by bending both ends of a single plate, it is possible to obtain the structure shown in FIG.
It is not necessary to make a hole in the bent part as in the conventional example, and the problem that the workability in the production process such as deformation of the hole at the time of opening does not occur, and the workability in the production process in the factory does not occur. Improvement and simplification of the production process can be achieved.

Further, since the inclined portion is fixedly joined to the roof surface portion, the strength of the roof surface portion is improved.

According to a second aspect of the present invention, the upper ends of the two roof surfaces are fixed to the upper surface of the roof beam serving as a ridge, and the connecting purlin is provided in a groove formed between the upper ends of the two roof surfaces. In the roof ridge structure in which a plurality of ridges covering the combined purlin are provided at intervals, in a region where the combined purlin is not disposed, a main bracket fixing bracket is fixed. Two inclined portions fixed to the upper end side of the two roof surface portions, a flat portion connecting the two inclined portions, and a main line connecting portion fixed to the flat portion; It is characterized in that a fixing bracket is covered by the ridge.

According to the second aspect of the present invention, unlike the first aspect of the present invention, the main rope connecting portion is integrated with the main fixing metal fitting itself. Claim 1 allows such a metal fitting for a master rope to be completely covered by a ridge packet.
The same operation and effect as those of the invention can be obtained.

In addition, construction work on the roof, including work near a dangerous eaves, can be performed while taking safety measures using a master rope. After the construction work near the roof ridge top except for the attachment of the ridges, the ties are removed from the ties of the ties, and then the ridges are fixed from above and the metal fittings for the ties are covered. Therefore, it is not necessary to take any special measures against rain leakage near the roof ridge top.
