Description

  The present invention is a construction of an agricultural greenhouse to prevent a worker from falling when constructing an upper part of an agricultural greenhouse such as construction of a roof portion or tensioning of a roof covering material during construction of an agricultural greenhouse. It relates to a time-lapse prevention net

  Conventionally, agricultural greenhouses have a simple structure and are not so high in height, and no special means for preventing workers from falling are provided during construction.

  However, in recent years, the size of agricultural greenhouses has increased, and those having structures similar to those of buildings have been developed. On the other hand, in the construction of agricultural greenhouses, there were some cases of crashes when performing the construction of the upper part.

  On the other hand, as this kind of crash prevention net, there has been no conventional one applicable to agricultural greenhouses, but as a fall prevention net for residential buildings, for example, the fall prevention described in JP-A-7-207953 The net is known. The fall prevention net described in the above-mentioned patent document 1 is safe in a hole in a beam in a state where a safety net hanging bracket is hung on an edge net of a fall prevention net and the safety net hanging bracket is set on an operation rod in a house construction work. In the configuration for inserting the net hanging metal fitting, it is configured in a torsional S shape including an insertion portion for inserting the operation rod, an insertion portion for inserting the hole of the beam, and a beam contact portion for preventing the removal.

In order to prevent the worker from falling during work at high places such as roof member installation work or roof covering material stretching work, for example, after the main aggregate is assembled, the roof part, etc. Before assembling at a high place, the main aggregate is stretched to prevent the operator from falling.

  FIG. 8 is a plan view of a fall prevention net according to the present invention. In the drawing, reference numeral 50 denotes a fall prevention net, and the fall prevention net 50 is formed in a substantially rectangular shape extending with the frontage direction X as the short side direction and the depth direction Y as the long side direction. A net body 51 made of a net formed of a synthetic resin such as nylon or polyester, and an edge net 52 that forms a side of the net body 51 and has a diameter larger than the net body (the edge rope 52a and the depth in the frontage direction X) The net body 50 includes a master rope 53 (a master rope 53a extending in the depth direction Y from the central portion in the frontage direction X and a column in the depth direction Y). It is formed so as to be partitioned at regular intervals in a grid shape by the master rope 53b) arranged in the interval dimension, and the strength is ensured.

  In addition, the second edge lines 54 and 54 are respectively connected to the edge line 52b and 52b toward the center of the frontage direction X toward the depth direction Y at positions spaced apart from each other. Further, at the intersection of the edge net 52 (52a, 52b) and the master rope 53 (53a, 53b), two suspension nets for binding and locking the fall prevention net 50 to a support member 55 is attached.

  The net body 51 preferably has a mesh of about 85 mm, and the fiber diameter is, for example, about 1670 dtex. On the other hand, the edge net 52 (52a, 52b), the second edge rope 54, and the master rope 53 are formed of ropes having a diameter of about 6 mm to 9 mm, which is thicker than the rope constituting the net body 51. This is required to be lightweight in order to transport and stretch the fall prevention net 50, and is preferably about 20 kg to 35 kg. Therefore, the edge net 52 and the second edge line 54 are preferred. Further, the master rope 53 is a large-diameter rope, the master rope 53 is arranged so as to be partitioned in a grid shape to ensure strength, and the rope constituting the net body 51 is made thinner and lighter than that. This is to reduce the weight. Further, the attachment strength is improved by attaching the suspension mesh 54 to the intersection of the edge net 52 (52a, 52b) having a large diameter and strength and the master rope 53.

  As a specific example, the fall prevention net 50 has tailored dimensions of about 9000 mm in the frontage direction X and about 15000 mm in the depth direction Y, and the second edge 54 is in the frontage direction. In X, an interval of about 1000 mm from both ends is arranged in the depth direction Y. Further, the master rope 53a is further attached to the central portion in the frontage direction X with an interval of about 3500 mm therefrom. In the depth direction Y, the master rope 53b is attached with an interval of about 3000 mm, which is substantially the same width as the column interval.

  As described above, the fall prevention net 50 is of a weight that can be carried by an operator alone, and is preferably about 20 kg to 35 kg so that a tensioning operation can be easily performed. The net 50 is preferably as large as possible so as to cover a wide area with a single sheet. As described above, tailored dimensions of about 9000 mm in the frontage direction X and about 15000 mm in the depth direction Y are preferable. Accordingly, the weight per unit area (square m) of the fall prevention net 50 is preferably about 0.149 kg to about 0.259 kg.

The fall prevention net 50 is stretched by attaching to the intersection portion). In this case, the edge nets 52b and 52b at both ends in the depth direction Y are not used and are in a suspended state.

  As shown in FIG. 9B, when the size of the frontage Z2 is 8 m, the frontage size of the fall prevention net 50 and the frontage size of one building approximately coincide with each other, so that the frontage direction X is provided. The suspension net 55 is fixed to the joint member 12 or the joint member 12 and the land beam 15, and the fall prevention net 50 is stretched.

    As shown in FIG. 9 (c), when the size of the frontage Z3 is 10 m, the frontage size is slightly less than twice the size of the fall prevention net 50. Two fall prevention nets 50 are used, and in one depth direction Y, they are attached by the second edge net 54 and stretched in a suspended state to match the dimensions.

  FIG. 10 shows an installation example when the fall prevention net 50 according to the present invention is installed in the agricultural greenhouse 30.

  As shown in FIG. 10, when the size of the frontage Z4 is 9 m, the frontage size matches the size in the frontage direction X of the fall-preventing net 50. Therefore, the suspension net 54 provided in the frontage direction X is The fall prevention net 50 is stretched and fixed to the truss beam 35.
