Abstract

(57) [Summary] [Purpose] To provide a fall prevention net for construction work that prevents workers who are frequently used in wooden construction from falling. [Structure] A human body support net A for preventing humans from crashing, and a vertical column or a horizontal column on the side of the building where the peripheral part of the human body support net A or the peripheral rope 1 and the crash opening 2 are open. A fall-prevention net for construction work, comprising a large number of tension ropes a each having a carabiner 4 attached to at least one end thereof stretched between a suitable fastener 3.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fall prevention net for construction work, which prevents a worker who is frequently used in construction, particularly a wooden construction, from falling.

[0002]

[Problems to be solved by conventional techniques and devices]

 In the past, workers often accidentally crashed during construction work, so a net was set up at the opening to match the size.

Since the tensioning of this net is troublesome, a large number of fastening ropes are previously attached around the net, and the fastening ropes are pulled and tied to the pillar to stretch the net at the opening. Was set up.

When the inventor removes or stores the safety net attached with this branch-shaped fastening rope, the fastening rope and the net are entangled, and in particular, they are often stored as a group. However, it was difficult to expand to the original expanded state of the net, and we focused on the fact that we could not install the net one after another, and we devised a fall prevention net for construction work that is extremely easy to install.

[0005]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

[0006] A human body support net A for preventing humans from crashing, and a vertical column or a horizontal column on the side of the building where the peripheral edge or the peripheral rope 1 and the crash opening 2 of the human body support net A are opened. The present invention relates to a fall prevention net for construction work, which comprises a large number of tension ropes a to which a carabiner 4 is attached at least at one end and which is stretched between a suitable fastener 3.

[0007]

[Action]

 Since the human body support net A is stored by itself, it can be easily expanded without worrying.

The tension rope a is stored separately, and is pulled by the carabiner 4 provided at one end of the tension rope a to the peripheral rope 1 of the human body support net A, and the other end is wound around a pillar and pulled by the carabiner 4, for example. By repeating the work, the human body support net A can be installed very easily.

【Example】

 The drawings show a preferred embodiment of the present invention, in which a human body support net A for preventing a person from falling and a building in which a peripheral portion 1 and a crash opening 2 of the human body support net A are opened It is composed of a large number of tension ropes a with a carabiner 4 attached at least at one end, which is stretched between a vertical column and a horizontal column on the side, and other suitable fastenings 3 such as floors, walls and reinforcing bars. It is related to the fall prevention net for construction work.

There are various implementation styles for the tension rope a.

3 shows a case where a carabiner 4 is attached to both ends, FIG. 4 shows a case where a carabiner 4 is attached to one side, and a ring 5 is attached to the other side, and FIG. 5 shows a carabiner 4 on one side and a rope ring 6 in which a rope is folded back on the other side. Is formed.

The tension rope a may be fastened by forming the tension rope a into a ring and winding the tension rope a around the peripheral rope 1 and the pillar of the human body support net A, or at both ends of the tension rope a respectively. The carabiner 4 may be folded back and fastened to the tension rope a, or one end of the carabiner 4 of the tension rope a may be fastened to the peripheral rope, and the tension rope a may be folded back to fix the carabiner 4 at the other end. You may fix it at intervals. In short, at least one carabiner 4 is used to tension the human body support net A in a tensioned state.

[0013]

[Effect of device]

 As described above, the present invention provides a human body support net that prevents a person from falling, and an appropriate stop such as a column or floor on the side of a building where the human body support net has a peripheral edge and a crash opening. Since it consists of a large number of tension ropes with a carabiner attached to at least one end that is stretched between the kimono and the kimono, the human body support net and the tension ropes can be stored separately, and therefore the human body support net. It is easy to expand when using it, and it is also possible to stretch it by using a separate number of ropes to pull and fasten it in a suspended state so that the human body support net can be stretched. It is a fall prevention net for construction work, which has excellent features that make work extremely easy.
