[Technical field to which the device belongs]

 The present invention relates to a roof fall prevention device, and more particularly to a roof fall prevention device installed on a roof to prevent a fall accident such as a roofing worker.

[0002]

[Prior art]

 As is well known, the roofing work is a heavy work in the open field on a slope with poor scaffolding, and is a dangerous work at a high place where there is always a risk of falling. In recent years, the roofing workers have become older, and the fall of workers has become a serious problem in the industry.

To date, as a countermeasure against this fall accident, there has been proposed a device in which a plurality of columns are erected on the roof and a net is stretched between the columns to prevent a worker from falling. However, in this net device, the support ropes must be stretched from the upper end of each strut in a hem-spreading manner in order to erect each strut vertically. There was a problem that the suspended support rope interfered with the work and reduced the work efficiency.

The technical means is adopted in which the distance between the roof tiles B, B ... arranged in a flat matrix on the base plate S is made larger.

Further, in order to solve the above-mentioned problems, the present invention, in addition to the above-mentioned means, when the frame body 2 is fitted into the fitting recess 11a of each strut body 1, the frame body 2 Has adopted the technical means that the roof slopes downward.

[0008]

[Embodiment of device]

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. 1 is an overall side view showing a state where the fall prevention device of this embodiment is installed on the roof, and FIG. 2 is a rear view showing a state where the fall prevention device is installed on the roof.

As shown in FIGS. 1 and 2, the fall prevention device of the present embodiment has a substantially L-shaped strut body 1 in which a lateral arm 12 is welded near a lower portion of a body 11 made of an aluminum material. ..; and a frame 2 made of an aluminum material that is detachably crossed over each of the body portions 11 of the plurality of pillars 1.1.

The substantially L-shaped strut body 1 is made of a square pipe made of an aluminum material and has high rigidity, and is also lightweight and rustproof. An aluminum-made plate 11b is provided in the vicinity of an inner corner of the L-shape with the arm 12 to form an upward fitting recess 11a. A leg portion 11c formed by welding a square pipe made of aluminum material is formed at the lower end of the body portion 11 of the strut body 1, and can be placed on the roof tile R.

Further, a claw portion 12a is provided at a tip end portion of the lateral arm 12 of the strut body 1 via a plate-shaped carry-out piece 12b made of stainless steel which is bent at a predetermined position. By 12a, it is possible to hook on one of the roof tiles B arranged in parallel on the roof base plate S.

In the present embodiment, as shown in FIG. 1, the distance from the foot portion 11c of the body portion 11 to the claw portion 12a at the tip of the lateral arm 12 is about three times the distance between the roof tile bars B, B ... Of the plurality of tile tiles BB arranged in parallel on the base plate S, the claw portion 12a is hooked to the fourth tile tile B from the bottom including the tile seat, so that the pillar body 1 The legs 11c of the body 11 are arranged at the lower end of the roof.

On the other hand, the frame body 2 of the present embodiment is formed in a plate shape by a square pipe made of an aluminum material, has high rigidity, and is lightweight and rustproof. A synthetic resin net 3 is tied inside the frame of the frame body 2.

By simply fitting the lower end of the frame body 2 into the respective fitting recesses 11a of the pillar bodies 1, 1, ... The frame body 2 can be removably placed horizontally on each of the body portions 11 of the pillar bodies 1, 1 ..., and the fall prevention device of this embodiment can be easily installed on the roof.

As described above, in the present embodiment, the strut body 1 is formed of a substantially L-shaped rigid body, and the frame body 2 to be crossed over the plurality of strut bodies 1, 1, ... Is also formed as a rigid body. Therefore, with the extremely simple assembly structure of inserting the lower end of the frame body 2 into the fitting recess 11a of the column body 1, it is possible to realize a fence structure that can sufficiently withstand the impact and load from above the roof. In addition, the hook 12a of the pillar 1 is hooked on the roof tile B, which is a simple and simple fixing mechanism, so that the device can be reliably installed on the roof. Therefore, unlike the conventional product, it is not necessary to fix the supporting column in a standing state by stretching the supporting rope in a skirt-wide manner, which simplifies the installation work and prevents the supporting rope from hindering the work.

Further, in the fall prevention device of this embodiment, the lateral arm 12 is formed to be long and the distance from the foot portion 11c of the strut body 1 to the claw portion 12a at the tip of the lateral arm 12 is determined by・ Since it is made larger than the space between B ..., even if a large impact or load is applied to the frame body 2 from above the roof, the foot portion 11c of the rigid L-shaped column body 1 serves as a fulcrum. Since it plays a role, the hooking portion between the claw portion 12a and the tile rail B is not easily disengaged, and a fall accident can be reliably prevented.

Furthermore, in the present embodiment, as shown in FIG. 1, when the frame body 2 is fitted into the fitting recessed portion 11a of each support body 1, the frame body 2 is tilted downward to the roof inclination. Therefore, in such an installed state, the frame body 2 leans against the body portion 11 of each strut body 1, so that the frame body 2 can be installed stably without easily rattling. It will be possible.

The embodiment, which is a specific example of the present invention, is generally configured as described above, but the present invention is not limited to the above-mentioned embodiment, and various modifications can be made within the scope of the “claim for utility model registration”. Can be changed.

For example, in the above embodiment, in order to simplify the installation work, a plate-shaped take-out piece 12b bent at a predetermined position is provided at the tip of the lateral arm 12, and a claw portion 12a is further provided at the tip portion. Although it is provided, of course, the claw portion 12a may be directly provided on the tip end portion of the lateral arm 12 to further simplify the configuration.

Further, in the above-described embodiment, the distance from the foot portion 11c of each strut body 1 to the claw portion 12a at the tip of the lateral arm 12 is set to about three times the distance between the tile bars B, B ... Of course, the present invention is not limited to this, and it suffices if it is larger than the interval between the roof tile bars B, B ... If the distance from the foot portion 11c to the claw portion 12a is increased, the load resistance of the preventive device can be increased, but the weight of the device itself is increased. The distance from the foot portion 11c to the claw portion 12a can be variously changed in consideration of the arrangement density of the plurality of pillars 1, 1, ... Installed on the roof.
