A ceiling portion of a net flat facility is configured by covering each girder member 1a, 1b, 1c and each purlin 2 with an insect net n. Insect insects are also attached to the front, rear, left and right side walls of the net flat facility so that no insects can enter the facility.

The inverted trapezoidal bar 3 attached and fixed to each girder member 1a, 1b, and 1c is used to place and support the load of the eaves 5. That is, the end of each arch pipe 4 of each ridge is attached and fixed to each inverted trapezoidal bar 3 and the ridge 5 is placed and supported. FIG. 3 is an enlarged view of this part, and both inverted trapezoidal ends 3e of the inverted trapezoidal bar 3 are inserted into the distal end 4e of the arch pipe 4 and fixed with rivets 6, on which the ridge 5 Is placed. Groove-shaped vignettes 7 are integrated in advance at both ends of the flange 5, and the binipets 7 and the respective arch pipe tips 4 e are connected and fixed by fixing brackets 8.

FIG. 4 is a side view of the structure shown in FIG. 3, in which the inverted trapezoidal bar 3 is mounted and fixed on a longitudinal beam member 1b. The U-shaped sheet metal 9 is attached to and covered with the girder member 1b from below, and the girder member 1b is inserted into the U-shaped sheet metal 9. Support holes 10 and 10 are formed at the tips of both arms 9a and 9b of the U-shaped sheet metal 9, and the inverted trapezoidal bar 3 is inserted through the support holes 10 and 10, respectively. In this state, the wedge 11 is press-fitted between the lower part of the girder member 1b and the bottom part 9b of the U-shaped sheet metal 9, whereby the inverted trapezoidal bar 3 in the support hole 10 is placed on the upper surface of the girder member 1b. It is fastened and fixed firmly. As a result, the nippet P on the girder member 1b is crushed by the tightening force. The insect trap net n is pierced and the tips of both arms 9a and 9b are inserted, and then the inverted trapezoidal bar 3 is inserted into the support hole 10 above the insect shield net n.

Thus, the tip 4e of the arch pipe 4 is inserted and connected to both ends of the inverted trapezoidal bar 3 firmly fixed on the girder member 1b. That is, screws 6 and 6 are screwed in from the side and fixed in a state where both ends 3e and 3e of the inverted trapezoidal bar 3 are inserted into the arch pipe ends 4e and 4e. The other ends of the arch pipes 4 and 4 are connected and fixed in the same manner to the inverted trapezoidal bar 3 on the beam members 1a and 1c on the other end side. In addition, between each arch pipe 4 and both ends 4e and 4e is a little bent in advance with a predetermined curvature, and by inserting and fixing the tip 3e of the inverted trapezoidal bar 3 to both ends 4e and 4e, The entire length of the arch pipe 4 is curved in an arch shape as shown in FIG.

As described above, the flange 5 is inserted and placed in the inverted trapezoidal space between the arch pipe tips 4e and 4e to which both ends 3e and 3e of the inverted trapezoidal bar 3 are inserted and connected as described above. The binipets 7 and 7 connected and fixed in advance to both edges of the flange 5 are connected and fixed to the arch pipe tips 4e and 4e. FIG. 5 is a perspective view of the connection fitting 8, and the tip of the arch pipe 4e can be inserted substantially vertically into the space S between both arms 8a and 8b of the connection fitting 8 bent in a U-shape. Further, when viewed from the side, upper and lower arms 8c, 8d of a forward-facing recessed space h into which the heel vinepet 7 enters are formed on both arm portions 8a, 8b. And the insertion nail | claw part 8e, 8f is formed in the part between both arm part 8a * 8b of the front-end | tip of the upper and lower arms 8c, 8d. The insertion claws 8e and 8f are portions that are fitted into the concavities 73 and 74 beyond the projections 71 and 72 projecting from the bottom of the bikini 7 of the heel, and are back portions of both arms 8a and 8b. Are provided with wedge insertion holes 8g and 8h.

In the connection operation, one insertion claw portion 8e of the connection fitting 8 is inserted into one constricted recess 73 of the binipette, and then the other insertion plate edge 8f is inserted into the other constriction recess 74 of the binnippet. In this state, the arms 8a and 8b of the connecting fitting 8 are covered with the arch pipe tip 4e, and the arch pipe tip 4e is inserted vertically into the space S between the arms 8a and 8b. Then, when the wedge 12 is press-fitted into the wedge insertion holes 8g and 8h on the backs of both arms 8a and 8b, the back of the vine pipe nippet 7 is fastened and fixed to the arch pipe tip 4e and the heel holding pipe 5e. The state of FIG. 4 is obtained.

In the ridge at the end (left side) in FIG. 1 and FIG. 2, the ridge 5 can be inserted and placed between the adjacent ridge on one side (right side), but there is no adjacent ridge on the other side (left side). Therefore, as shown at the left end of the left ridge in FIG. Therefore, the right side of both ends 3e and 3e of the inverted trapezoidal bar 3 is inserted and fixed to the arch pipe tip 4e, whereas the left end 3e is only the tip part 4e of the arch pipe as shown in FIG. It has a structure in which it is inserted and fixed to the bag holding pipe 5e having the remaining shape. Eventually, one end 3e of the inverted trapezoidal bar 3 is inserted and fixed to the tip 4e of the arch pipe, while the other end 3e is inserted and fixed to the heel holding pipe 5e. Note that the lengths of both ends 3e and 3e of the inverted trapezoidal bar 3 are arbitrary, and if the length is longer than the attached position of the binipette 7, the arch pipe can be inserted and connected to a straight arch pipe to both ends. It is not necessary to bend both ends of the pipe, and the hook holding pipe 5e is unnecessary.

FIG. 7 is a side view in the BB direction of FIG. 1 and shows a state on the wife side of each building. At both ends on the wife side of each building, the arch pipe 4 at the end of the wife side and the beam 13 on the wife side are connected by several wife connecting pipes 14. Since the arch pipe 4 at the end of the wife side is disposed, for example, several tens of centimeters from the support column or beam 13 at the wife side of the net flat facility, the wife connection pipe 14 has an inclination of, for example, about 45 degrees. It is installed. As a result, even if a strong wind is received from the wife side, the strong wind can be diverted to the upper side of the arch pipes 4. Further, since the wife-side arch pipe 4 is pulled obliquely by the wife connecting pipe 14 at both ends of each building, it is possible to prevent the arch pipes 4 between the wife at both ends from falling down. Since each arch pipe 4 is connected by a purlin pipe 15 as shown in FIG. 1 to ensure stability, there is no fear that each arch pipe 4 falls.

As described above, the arch pipes 4 of each ridge are assembled, and in the state where the ridges 5 are attached to the end portions between the ridges, a rain protection sheet such as a vinyl sheet is placed on each arch pipe 4. And the edge part of the arch pipe both ends side of a rain protection sheet is pushed in into the nippet 7 of a both-ends edge, and it fixes. That is, when the zigzag spring is pushed into the concave groove of the binippet 4 from above the end of the rainproof sheet to free the zigzag spring, the rainproof sheet is firmly attached and fixed in the vignette 7 by the spring force. The

In areas with many typhoons, such as Okinawa, the arch pipe 4… Rather than keeping the rain protection sheet on the top, when the typhoon hits, remove the rain protection sheet from the top of the arch pipe 4 in advance. It is necessary to keep. In addition, it is necessary to remove the rain protection sheet when adding moisture to the farm in the net flat facility by natural rainfall. As described above, when it is necessary to remove the rain protection sheet, it is advantageous to collect and collect at the depressed positions between the ridges, instead of completely removing and removing them. That is, when the rain protection sheet is not required or when a typhoon strikes, the other fence 5 is peeled off and removed from one end of the rain protection sheet on the arch pipe 4. Move to the side and accumulate. Although it is possible to completely remove the rain protection sheet and replace it with a new one, it is costly, and the burden of the replacement work is heavy, so it is impossible for one person, so it is easy to accumulate on the fence. It is.

By the way, in the summertime when the sunlight is strong, there is a risk that the rain protection sheets accumulated on the reeds may be deteriorated and damaged by high heat, or the rain protection sheets may be heat-sealed. In order to avoid this, if the light shielding net is put on the rain protection sheet accumulated on the fence 5 as described above, it is insulated by the light shielding effect, so the rain protection sheet is deteriorated and damaged by high heat, It is possible to prevent heat fusion.

FIG. 8 is an embodiment using a wire for inserting an inverted trapezoidal bar instead of the U-shaped sheet metal 9, (1) is a ring-shaped wire, (2) is a support hole 10 at both ends, 10 is a binaural wire. As in (1), for example, a high-strength wire formed by twisting a wire in a rope shape is connected to form an endless ring. When this annular wire is folded in half and covered from the lower side of the girder member 1b like the U-shaped sheet metal 9 in FIG. 3, semicircular holes corresponding to the support holes 10 and 10 are formed at both ends. Therefore, the inverted trapezoidal bar 3 can be inserted into the semicircular holes 10, 10, and the structure is exactly the same as in FIGS. 3 and 4. By driving the wedge 11, the inverted trapezoidal bar 3 is used as the girder member. It can be firmly tightened and fixed on 1b.

(1) Leave the support holes 10 and 10 at both ends of the annular wire shown in the figure, and integrate the other parts in a parallel state, or twist them together to make a single piece. Become. Also in this case, the inverted trapezoidal bar 3 can be inserted into the support holes 10 and 10 at both ends by covering the integrated wire portion W from the lower side of the beam member 1b. Thus, when a wire is used in place of the U-shaped sheet metal, damage to the net can be greatly reduced when the flat net is passed upward, or damage can be eliminated. When the wire is folded in half, the bent portion becomes semicircular, and the wedge is preferably a semi-cylindrical body. In this case, the diameter of the wedge is preferably about the same as the width dimension of the beam member 1b. The above inverted trapezoidal bar 3 may be a rod-like body such as a reinforcing bar or a hollow pipe-like body.

In the above embodiment, the distance between the spar members 1a, 1b, and 1c is, for example, 6 m, the total length in the spar direction is, for example, 30 m or more, the cross-sectional dimension of the spar member is, for example, 75 mm × 45 mm, and the outer diameter of the arch pipe 4 is, for example, 22 mm. The outer diameter of the inverted trapezoidal bar 3 is, for example, 19 mm, but it goes without saying that it is not limited to these dimensions. Each girder member 1a, 1b, 1c can use round steel instead of square steel.

As described above, according to the present invention, the paddle mounting means is attached and supported using the girder members arranged at predetermined intervals on the ceiling of the net flat facility that surrounds the cultivation field with insect repellent nets, Since each arch pipe between adjacent spar members is fixed using 樋 mounting means, it can be easily mounted on the spar members simply by breaking through the net in existing net flat facilities. It is possible to add a placing means, connect and fix the arch pipes, and cover the rain protection sheet, thereby realizing a simple rain protection structure that can be constructed by one person.
