  The upper guide sheet 31 is overlapped with the lower guide sheet 32 while being offset in the width direction on the sheet member side (hereinafter referred to as the inward side). Therefore, a part of the lower guide sheet 32 (hereinafter referred to as a fin portion 322) is exposed along the longitudinal direction.

  The fin portion 322 extends a predetermined length outward from the edge of the upper guide sheet member 31, and the threading member 34 is positioned on the fin portion 322.

  Specifically, as shown in FIG. 3, the upper (left side in FIG. 3) guide sheet 31 is bent with reference to the edge S of the lower (right side in FIG. 3) guide sheet 32, and the lower side guide sheet 31 is bent. Overlay on the guide sheet 32. Thereby, the through hole 33 is defined by the fin portion 322 of the lower guide sheet 32 and the through member 34.

In other words, the two guide sheets 31 and 32 of the present embodiment are offset and overlapped so that the through member 34 forms the through hole 33.
As shown in FIG. 3, in the present embodiment, the lower guide sheet 32 is formed wider than the upper guide sheet 31 by the width (or offset) of the through member 34.
As a result, as shown in FIG. 4, when the upper guide sheet 31 is overlapped with the lower guide sheet 32, the inner side edges (right side in FIG. 4) of both guide sheets 31, 32 coincide. It is supposed to be.
As described above, the width of the lower guide sheet 32 is larger than the width of the upper guide sheet 31 with the width of the threading member 34 as a guideline. However, the present invention is not limited to this. In FIG. 4, the inner edge of the lower guide sheet 32 may not necessarily coincide with the upper guide sheet 31. That is, the lower guide sheet 32 need not be formed wider than the upper guide sheet 31.

  The upper guide sheet 31 and the lower guide sheet 32 are joined so as to form a guide portion 35 having a Y-shaped cross section for guiding the rope 4.

  Specifically, the upper guide sheet 31 and the lower guide sheet 32 are joined to each other at a position on the inner side (sheet member 2 side) by a predetermined distance from the edge S of the upper guide sheet 31. A guide portion 35 that is bifurcated outwardly from the joining position C is formed.

  In the present embodiment, the joining position C is set to a position overlapping the edge of the sheet member 2, and the upper and lower guide sheets 31 and 32 are stitched to the sheet member 2 at the joining position C, and the sheet member 2 is interposed therebetween. Are joined together and attached to the sheet member 2.

The guide sheets 31 and 32 are formed of a planar member having a waist so that the rope 4 can be guided. The guide sheets 31 and 32 have a strength that can withstand wind pressure applied to the sheet member 2.
In the present embodiment, the lower guide sheet 32 is the upper guide sheet 31 in order to improve workability such as sewing work of the guide sheets 31 and 32 and the sheet member 2 and to improve the scenery at the time of installation. On the other hand, the net width is increased by the width of the threading member 34, and the knitted net is sewn.

  Returning to FIG. 1, a plurality of through members 34 are provided at predetermined intervals along the longitudinal direction of the guide sheets 31 and 32. In the present embodiment, the length of each passing member 34 in the longitudinal direction and the interval between the passing members 34 and 34 are set to be approximately equal.

  As shown in FIG. 4, each through member 34 extends from the edge portion S of the lower guide sheet 32 to the edge portion of the upper guide sheet 31 across the fin portion 322 to partition the through hole 33.

  In the present embodiment, each threading member 34 is formed such that a plurality of strands are arranged along the edge of the guide sheet 31 (32). More specifically, each threading member 34 is formed by alternately weaving one strand of yarn on the edge of the guide sheets 31 and 32.

  The twisted yarn (that is, the threading member 34) is formed of, for example, synthetic fiber, and in the present embodiment, is formed of synthetic fiber such as polyethylene as with the guide sheet 31.

  Returning to FIG. 1, the connecting members 3 configured as described above are respectively attached to the sheet members 2 to be connected, and the through members 34 of both the connecting members 3 are provided alternately. That is, the connecting member 3 is provided so that the through member 34 of one connecting member 3 is positioned between adjacent through members 34 in the other connecting member 3.

  As shown in FIG. 4, the sheet member 2 includes a mesh sheet 21 for preventing the paint from scattering. In the present embodiment, the sheet member 2 includes double mesh sheets 21 and 21, and a predetermined gap is provided between the mesh sheets 21 and 21.

  The wire member is composed of a rope 4 in the illustrated example, but a rod, a pipe, and the like are also conceivable.

  Next, the operation of the sheet structure 1 of the present embodiment will be described.

  As shown in FIG. 5, the connection between the sheet members 2 and 2 is performed by first facing both the sheet members 2 and 2 so that the surfaces on the side of the through holes 33 face each other. It is carried out alternately through the through holes 33 of both sheet members 2 to be connected. For example, a string passing rod or the like is attached to the tip of the rope 4, and the string passing rod and the rope 4 are inserted into the through holes 33 defined by the threading member 34.

  When inserting the rope 4, the rope 4 is fed along the guide sheet 32 while pressing the tip of the rope 4 or the tip of a stringing rod against the guide sheet 32 (fin portion 322).

  Here, in this embodiment, since the guide sheet 32 (31) has sufficient hardness so that the tip of the rope 4 and the like can be guided and is densely formed so that the tip of the rope 4 is not caught, Even if the thread of the threading member 34 that divides the through-hole 33 is flattened or has entered (deformed into a concave shape), the rope 4 is guided on the guide sheet 32 without being caught by the thread. Pass through the through-hole 33 smoothly.

  Furthermore, after the rope 4 is inserted into the through hole 33, the rope 4 prevents the thread of the through member 34 from being deformed inside the through hole 33 and sinking in.

  As described above, the sheet members 2 and 2 are connected by inserting the rope 4 into the through holes 33 of the connection members 3 of the sheet members 2 and 2 to be connected.

  Thus, in the sheet structure 1 of the present embodiment, the through hole 33 is formed on the guide sheet 31 by the through member 34, and therefore, when the rope 4 is inserted into the through hole 33, the rope 4 is guided by the guide sheet 31. The rope 4 can be easily inserted.

  As a result, it is possible to improve the workability and efficiency of the connecting work of the sheet member 2 in painting work and the like, and to reduce the work cost.

  Further, since the rope 4 can be guided by the Y-shaped guide portion 35, the rope 4 can be easily inserted through this.

  Further, as shown in FIG. 6, in a state where both the sheet members 2, 2 are connected, the through holes 33 of both the connecting members 3 are aligned along the ropes 4, and the ropes 4 are connected to the fins of the connecting members 3. It is sandwiched from above and below by the portion 322.

  As a result, the connected sheet members 2 and 2 are sealed by the fins 322 that are overlapped.

  Further, the threading member 34 of the other sheet member 2 (coupling member 3) is positioned between the threading members 34 of the one sheet member 2 (coupling member 3), and the threading members of both sheet members 2 and 2 are located. 34 are engaged.

  Thereby, both the connection members 3 and 3 (sheet | seat members 2 and 2) contact | adhere mutually, and are connected without a substantially clearance gap.

  Thus, in this embodiment, since the fin part 322 of the connection member 3 is wrapped when the sheet member 2 is connected (see FIG. 6), force is exerted in a direction in which both the sheet members 2 and 2 are pulled apart by wind pressure or the like. Even if added, a gap does not occur between the sheet members 2 and 2.

  In addition, in the present embodiment, since a predetermined gap is provided between the double mesh sheets 21, 21, even if the paint escapes from the mesh sheet 21 on the inner side (steel tower side) during painting, The momentum of the paint can be weakened by the gap (air) between the sheets 21 and 21, and the paint can be reliably received by the mesh sheet 21 on the outer side.

  Further, by forming the guide sheet 31 and the through member 34 with the same material, it is not necessary to separate them when they are discarded, and the disposal cost can be reduced.

  In addition, by forming the guide sheet 31 and the through member 34 from a flexible material such as synthetic fiber, the sheet can be easily folded or rolled when the sheet is transported or accommodated.

  In addition, this invention is not limited to the above-mentioned embodiment, Various modifications and application examples can be considered.

  For example, the sheet structure is not limited to painting work, but should be applied to various construction sites such as construction work, civil engineering work (banking, slope nets, etc.) and protective sheets used to protect buildings from falling objects such as snowfall. Can be considered.

  Further, the connecting member is not limited to that of the above-described embodiment. For example, as shown in FIG. A plurality of openings 72 may be provided, and the sheet 71 may be folded back with the edge S of the opening 72 as a reference. In this case, the sheet portion positioned between the adjacent openings 72 and 72 forms a through member, and the sheet portions on both sides of the opening 72 form each guide sheet.

  Moreover, in this embodiment, although the connection member 3 was attached to the edge of the sheet member 2, it is not limited to this, For example, you may make it attach the connection member 3 to the intermediate part of the sheet member 2. FIG.

  That is, as shown in FIG. 8, both guide sheets of the connecting member 3 may be sewn at a middle position in the width direction of the vertically long sheet member 2. In this case, since the sheet member 2 can be connected at an intermediate position in the width direction, for example, when a plurality of sheet members 2 are connected in a cylindrical shape so as to surround the steel tower, the peripheral length can be easily adjusted. it can. In addition to the rope, a power cable or the like may be inserted into the through hole of the connecting member 3.

  In addition, the guide sheet 31 and the threading member 34 are preferably integrally formed from synthetic fibers as in the present embodiment, but are not limited thereto, and may be formed separately, or may be made of a material other than synthetic fibers. It may be formed.
