Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to the construction of a protective net for preventing accidents such as falls at horizontal openings in confined spaces, such as construction sites.

Conventional Technology Conventional disaster prevention techniques include, for example, the use of brackets and scaffolding boards, and the use of single pipes and fall prevention nets.

Problems to be Solved by the Invention However, the above-mentioned conventional curing techniques cannot be used for narrow horizontal openings such as recesses on the outer periphery of buildings. There was a problem that it was heavy and difficult to transport on the completed scaffolding, and conventional nets had problems such as being difficult to tighten in tight places and not being effective in preventing falls.

This invention was developed to solve the above-mentioned conventional problems, and its purpose is to provide a disaster prevention device that is lightweight, easy to transport, easy to install and remove, and that is always taut to prevent falls. The purpose is to provide a health net.

Means for Solving the Problems The disaster prevention curing net of the present invention includes a pair of rod members each having a connecting member attached to the supporting member, and one end of the rod member attached to the other rod member. It is characterized in that it is comprised of two cables attached to the other rod member on the other side so as to be adjustable in length, and a net member stretched between the cables.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a support member such as a single tube, which is fixed and extended to a fixed member such as a scaffold.

Reference numeral 2 denotes a rod member, which is latched onto the support member 1 by a connecting member 3 consisting of, for example, a chain 3a and a hook 3b as shown in FIG.

Reference numeral 4 denotes a cable such as a rope or wire, and one end 4a thereof is connected to one of the rod members 2. The other side 4b of the cable 4 is connected to the other rod member 2
It is inserted through a hook ring 2a attached to the rod member 2, and is fixed in a taut state between the left and right rod members 2. The cable 2 can be fixed by fastening it to the hook ring 2a or the rod member 2 with an appropriate tightening device, or by fixing the cable 4 to the hook ring 2a or the rod member 2.
Either make a lump in the cable or tie the two cables 4, 4 tightly together to prevent them from coming off the hook ring 2a. The cables 4 are stretched in parallel between the left and right rod members 2 with appropriate spacing between them, and a net member 5 is stretched between them.

The length of the cable 4, that is, the length of the net member 5 is 2.
It is attached to the cable 4 via a plurality of slide rings 5a so as to be tensioned evenly (homogeneously) according to the distance between the book rod members 2,2.

Therefore, when the main net is removed and transported or stored, it can be compacted by pulling the other side 4b of the cable 4 and drawing the left and right rod members 2 together, as shown in FIG. be able to.

If the rod member 2 is constructed to be expandable and fixed, the spacing between the cables 2, 2 can be changed, and the width of the net member 5 can be changed depending on the depth and width of the horizontal opening. It can be adapted.

Effect of the invention 1: The other end of the cable is inserted through the hook ring attached to the rod member, and the net member is stretched over the cable via a plurality of slide rings, so that a pair of The spacing between the bar members can be changed freely and easily, and as a result,
It can be adapted to various sizes of horizontal openings.

2. The left and right rod members can be pulled together and compacted simply by pulling the end of the cable without folding the net member, making it easy to transport and store.
