Abstract

PURPOSE:To prevent falling off from a roof without impairing the operating easiness by coupling one end of a sub-rope to each support pole at the roof periphery, and arranging a main rope between the other ends of the sub-ropes in the position innermore by a certain distance from the roof periphery. CONSTITUTION:One end of each sub-rope 12 is coupled with support poles 11 provided at the periphery of a roof, and a main rope 13 is stretched between the other ends of the sub-ropes 12 in the position innermore by 60-120cm, normally 90cm, from the periphery, and thus a rope device structure is configured. A coupling tool 14 with return stopper is furnished at the other end of the main rope 13. Provisional lining is performed with this coupling tool 14, followed by regular process of lining using a turn buckle 15. Further, the main rope 13 is installed approx. 90cm inside of the roof periphery. Thereby falling-off from the roof can be prevented without impairing the working effectiveness on the roof.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an installation structure for a rope for roof work, which is suitable for use when constructing a unit building.

[Prior Art] Even when constructing unit buildings, safety measures are taken for construction work at high places, as described in Japanese Utility Model Application Publication No. 173850/1983. When working on a roof, workers need to be sufficiently alert to avoid falling from the outer periphery of the roof. Utsukai Showa 56-12
Japanese Patent No. 1832 proposes a temporary handrail attached along the outer periphery of the roof to prevent falls. this is,
A large number of handrails with supports are installed around the outside of the roof.

[Problem to be solved by the invention] However, since the above-mentioned conventional method has a temporary handrail attached to the outer periphery of the roof, there is a risk of climbing over the handrail and falling, and it also causes psychological damage to the worker. It was putting pressure on me. When performing work on the roof around the roof, such as installing eaves, it is desirable to structurally provide a work environment free from the risk of falling without impairing work efficiency.

An object of the present invention is to reliably prevent the risk of falling while working on a roof without impairing work efficiency.

[Means for Solving the Problems] The present invention as set forth in claim 1 provides a structure in which the support poles are fixed to the frame at the peripheral corners of the roof, one end of the sub-rope is connected to each support pole, and the other end of each sub-rope is connected to the support pole. A main rope is stretched between them, and the main rope is installed inside the outer periphery of the roof.

The present invention according to claim 2 is the present invention according to claim 1, in which the parent rope is further installed 60 to 120 c+1 inside from the outer periphery of the roof.

According to a third aspect of the present invention, in the first aspect of the present invention, the support pole is further fixed to the head of a column located at a peripheral corner of the roof.

In the present invention, installing the main rope inside the outer periphery of the roof means that there is a place where work can be done on the outer periphery of the main rope. Therefore, the parent rope should be placed 60 to 120 cm inside the outer circumference of the roof, particularly preferably 80 to 100 cm.
It is preferable to install it inside the cm.

[Function] According to the present invention as described in claims 1 to 3, there are the following effects (1) and (2).

■When working on a roof, the safety of workers working inside the main robe is ensured by the presence of the main robe. At this time, the worker does not need to put a safety belt on the main rope, and extremely good workability is ensured.

■When working on a roof, workers working outside the main rope can be kept safe by placing a safety belt on the main rope. At this time, since the main rope is installed, for example, about 1 m inward from the outer circumference of the roof, the workability of eaves attachment, for example, on the outer circumference of the roof is not impaired.

[Example] Fig. 1 is a schematic diagram showing the construction state of a unit building to which the present invention is applied, Fig. 2 is a schematic diagram showing the fixed state of the support pole, and Fig. 3 is a schematic diagram showing the connected state of the sub rope. , 4th
The figure is a schematic diagram showing the fixed state of the main rope, Fig. 5 is a schematic diagram showing the tensioning state of the main rope, Fig. 6 is a schematic diagram showing the support pole, Fig. 7 is a schematic diagram showing the sub-rope, and Fig. 9 is a schematic diagram showing a parent rope, FIG. 9 is a schematic diagram showing a connector with a detent, and FIG. 10 is a schematic diagram showing a turnbuckle.

When constructing the present invention, for example, as shown in FIGS. 6 to 10, a support pole 11, a sub-rope 12, a parent lobe 13, a detent connector 14, a turnbuckle 15, etc.
is used.

Below, the parent rope 1 during construction of the unit building 20
The installation structure of No. 3 will be explained according to its installation work procedure.

(1) At the four corners around the roof of the building unit 21,
The support pole 11 is screwed onto the unit lifting nut installed at the head of the column 22 and fixed (see Figure 2).
.

(2) Connect the carabiner 12A provided at one end of each sub-rope 12 to the attachment link 11A of each support pole 11 (see FIG. 3).

If the carabiner 12A has a retaining tube 16, the tube 16 is screwed into the carabiner 12A to prevent it from coming off.

(3) Carabiner 13 provided at one end of parent lobe 13
A is connected to a carabiner 12B provided at the other end of any sub-rope 12 (see FIG. 4).

(4) Pass the middle part of the main rope 13 through the carabiner 12B provided at the other end of all the sub ropes 12 other than the sub rope 12 used in (3) above (see FIG. 5), the other end of the main rope 13 A connector 14 with a detent is provided in the section (fourth
(see figure).

(5) Connect the detent connector 14 to the turnbuckle 15
Connected to a carabiner 15A provided at one end, and a carabiner 15B provided at the other end of the turnbuckle 15.
Connect to the carabiner 12B of the sub rope 12 used in (3) above (see Fig. 4).

(6) Then, the tension of the parent lobe 13 is adjusted by performing board tensioning using the detent connector 14 and final tensioning using the turnbuckle 15. thus,
The parent rope 13 was installed 90 cm inside the outer periphery of the roof.

Note that the detent-equipped coupling 14 is connected to the detent release lever 1.
4A and a connecting arm 14B.

According to the above embodiment, there are the following effects (1) and (2).

- When working on the roof, the safety of workers who work inside the main robe 13 is ensured by the presence of the main robe 13. At this time, there is no need for the worker to put a safety belt on the main rope 13, and there is no psychological pressure, and extremely good workability is ensured.

- When working on the roof, the safety of workers who go outside of the main rope 13 is ensured by putting a safety belt around the main rope 13. At this time, since the main rope 13 is installed, for example, about 1 m inward from the outer circumference of the roof, the workability of eaves installation, etc., on the outer circumference of the roof, for example, is not impaired.

[Effects of the Invention] As described above, according to the present invention, the risk of falling during roof work can be reliably prevented without impairing work efficiency.
