JPH076375Y2 - Safety net stop - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention mainly relates to a safety net stopper used during construction work of a wooden house.

(Prior art and problems to be solved) Even in the case of a wooden house with two or three floors, it is necessary to give sufficient consideration to the fall prevention during the building work of the house. Therefore, a safety net of a size that fits the width of the cross beams and the depth is stretched across the cross beams via a hanging band.In this case, the strength of the hanging band and the strength of the fasteners In addition, it is necessary to wrap it around the horizontal beam, adjust the band length by the thickness of the horizontal beam, and further connect the fastening metal fittings when connecting it to the edge of the safety net. Was inconvenient. Further, in mounting such a suspension band, inconvenience such as scratching the horizontal beam is unavoidable.

(Purpose of the Invention) The present invention has been made based on the above circumstances, and the installation work on the horizontal beam is simple and reliable, there is no risk of scratches on the horizontal beam, and the hemline of the safety net is directly locked. It seeks to provide a possible safety net stop.

(Means for Solving the Problem) Therefore, in the present invention, as clearly shown in the illustrated embodiment, on both sides of the inverse channel type supporting member (1) that matches the cross section of the cross beam (A), A hook (2) for engaging the edge rope (4) of the safety net (3) is mounted upward.

(Operation) Therefore, even if the safety net (3) is blown by the wind, the support member (1) is not likely to rub against the horizontal beam (A), and at the time of installation, the reverse channel portion is simply crossed. The safety net (3) is simply attached to (A), and the hook rope (4) is hooked on the hook (2). There is no trouble and the support member (1) is attached.
Of the hook and the strength of the hook (2),
It is possible to securely and safely hold the safety net without the risk of a fastening failure such as a hanging band.

Embodiment An embodiment of the present invention will be specifically described below with reference to the drawings. In the figure, reference numeral 1 is a support member having an inverse channel type, and the inner width w thereof is the width W of the lateral beam A to be used.
On the other hand, the size is set such that w≈W and w> W. On the outer surfaces of both sides of the support member 1, hooks 2, 2 that face upward are attached by means such as welding.

Then, as shown in FIG. 3, the above-mentioned support member 1 is fitted with a ceiling beam, for example, a ceiling beam of the first floor, which has already been built in, from above to the transverse beam A, and is adjusted to the frontage and the depth between the transverse beams A and A. The rope 4 of the safety net 3 having a size is engaged with the hook 2 so that the safety net 3 is stretched between the transverse beams A, A.

In this case, the brim 4 only has to engage the hook 2. Thereby, the support member 1 straddling the cross beam A
The safety net 3 can be held safely and reliably via the.
If the fitting inner wall of the support member 1 is lined with a rubber layer or the like, it is possible to prevent the transverse beam A from being attached with scratches and to realize a sufficient fit without play.

In the embodiment, the case where the safety nets 3 are stretched on both sides of the transverse beam A has been described, but in the case of mounting the safety nets 3 on only one side, as shown in FIG.
The bridle 4 of the safety net 3 is attached to the hooks 2 on both sides of the support member 1.
It goes without saying that two steps may be applied.

(Effect of the Invention) The present invention has been described in detail above, and the supporting member 1 is laid across the cross beam A, and the hook ropes of the safety net 3 are directly locked by the hooks on both sides thereof. Since this is done, it can be attached to the transverse beam A while ensuring sufficient strength, and the safety net 3 can be supported reliably and safely. In this case, unlike the hanging band, the horizontal beam A is not scratched in the process of handling, and the band length is adjusted and troublesome mounting for securing the fastening force for connecting to the net is required. It can be omitted.
