It is a figure which shows the relationship between the pin piece of a frame body of a mesh-shaped ceiling material, and a wire, (a) shows a side surface, (b) shows a plane. It is a disassembled perspective view which shows the frame of a mesh-shaped ceiling material, a pin piece, and a wire. It is a figure which shows the binding band used for a mesh-like ceiling material.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a mesh ceiling material according to an embodiment. The mesh-like ceiling material is attached to a ceiling base material of a building to form a ceiling surface, and the ceiling is decorated or separated from the upper space and the lower space by a mesh-structured ceiling surface assembled in a mesh shape. The use of the mesh-like ceiling is various for decoration of the ceiling, prevention of invasion of animals (such as birds) or objects (such as balls).

  The mesh ceiling material 2 includes frame members 4 that form four sides around a quadrangle, and a plurality of wires 6 arranged in the frame members 4. The frame member 4 includes upper and lower frame members 4 and 4 on both sides and left and right frame members 4 and 4. Here, the above and below means the back side and the near side in the figure, and the left and right means the left side and the right side in the figure.

The wire 6 includes a plurality of wires 6 arranged vertically between the upper and lower frame members 4 and 4 and a plurality of wires 6 arranged horizontally between the left and right frame members 4 and 4. Here, the number of the wires 6 arranged vertically is five, and the wires 6 arranged horizontally are also five.
The frame member 4 and the wire member 6 are made of aluminum, light metal, or the like for weight reduction. In addition, a steel material or a synthetic resin material can be used as the frame material 4 and the wire material 6.

The overall shape of the mesh ceiling material 2 is a square shape. As other shapes, a rectangular shape such as a rectangle, a rhombus, a parallelogram, or the like can be used.
Further, the size of the mesh ceiling material 2 (outside of the four frame members 4) is 892 mm in length and 892 mm in width here. There is no particular limitation on the size, but it is appropriate to determine a smaller size when the mesh interval by the wire 6 is narrow, and a larger size when the mesh interval is wide.

In addition, as the frame member 4, an angle member having an L-shaped cross section including a vertical plate portion 12 and a horizontal plate portion 14 intersecting at right angles with the vertical plate portion 12 is used here. In this frame member 4, the width (height) of the vertical plate portion 12 is 12 mm, and the width of the horizontal plate portion 14 is also 12 mm. Moreover, the plate | board thickness of each part of the frame material 4 is 2 mm of vertical board parts, and 2 mm of vertical board parts.
Since the vertical plate portion 12 and the horizontal plate portion 14 of the frame member 4 have the same shape, there is no difference in shape, but the vertical plate portion 12 is arranged vertically, and is arranged horizontally. It is the horizontal plate portion 14. Further, the vertical plate portion 12 has a form in which the vertical plate portion 12 is arranged upward from the horizontal plate portion 14 and a form in which the vertical plate portion 12 is arranged downward.

  Then, as shown in FIG. 2, pin pieces 8 are provided at right angles to the frame material 4 (transverse plate portion 14) at a predetermined interval at the end of the horizontal plate portion 14 of the frame material 4. The interval (W) at which the pin pieces 8 are arranged is also the interval between the meshes of the mesh-like ceiling material 2 (adjacent wire rods 6).

Here, the pin piece 8 has a rectangular cross section with a rectangular shape of 2 mm in length and 2.5 mm in width. The length of the pin piece 8 is 5 mm to 30 mm, preferably about 10 mm to 20 mm, for example, 15 mm.
As shown in FIG. 3, the pin piece 8 can be inserted into the cylindrical hole portion 16 of the wire 6 with a margin.

The interval (W) for arranging the pin pieces 8 is about 145 mm here. The size of the interval (W) depends on the purpose of the mesh structure or the purpose of isolating the top and bottom of the mesh surface, but is practically about 50 mm to 250 mm, or about 100 mm to 200 mm.
The pin piece 8 has a rectangular cross section here, but may be a polygonal shape or a circular shape. The reason why the cross section is rectangular is that it is easy to manufacture.

  And the pin piece 8 is provided in the state which protruded sideways in the horizontal board part 14 of the frame material 4. As shown in FIG. There are various methods for providing the pin piece 8, but here, the horizontal plate portion 14 of the frame member 4 and the pin piece 8 are integrally formed by pressing to form the pin piece 8. For this reason, the horizontal plate portion 14 and the pin piece 8 are integrated (seamless), and thereby the strength is increased so that the pin piece 8 cannot be removed.

In addition, the method of providing the pin piece 8 in the horizontal plate part 14 includes a method of bonding the pin piece 8 to the horizontal plate part 14 by welding, a method of bonding using an adhesive, or the like. Moreover, a small hole is provided in the horizontal direction in the horizontal plate part 14, the tip of the pin piece 8 is formed (sharpened) to the size of the small hole, and the pin piece 8 is inserted into the small hole and joined (reinforceable with an adhesive or the like). There is also a method.
And the pin piece 8 is formed in all the upper-and-lower frame materials 4 and 4 and the right-and-left frame materials 4 and 4 which comprise the mesh-shaped ceiling material 2 at the said space | interval (W).

  The wire 6 is a long cylindrical material (circular cross section). In addition, the wire 6 is a tubular material (pipe) having an outer diameter of 6 mm and an inner diameter of 4 mm, and the thickness of the tube is 1 mm. For this reason, the thickness of the wire 6 has a diameter of 6 mm, and the insertion portion of the pin piece 8 has a cylindrical hole portion 16 having a diameter (inner diameter) of 4 mm. The length of the wire 6 is 868 mm here.

The thickness of the wire 6 is appropriately determined according to the overall size of the mesh ceiling material 2. When this is large, the wire 6 is also formed thick, and when it is small, the wire 6 is formed thin.
In addition, as the cross-sectional shape of the wire 6, it may be a polygonal rectangular tube or an elliptical tube. Alternatively, only the portion of the cylindrical hole portion 16 into which the pin pieces 8 at the left and right end portions of the wire 6 are inserted is formed into a cylindrical shape (hollow), and the others are formed into a shaft shape (solid). Good.

Next, a method for assembling the mesh ceiling material 2 will be described.
When assembling the mesh ceiling material 2, first, the frame members 4, 4 are arranged with the pin pieces 8 facing the inner side (the wire 6 side) on the top and bottom, respectively. Then, one end portion and the other end portion of the wire member 6 oriented vertically are inserted into the pin pieces 8 of the frame members 4 and 4 arranged vertically, and five pieces are vertically arranged at the above-mentioned interval (W). The wire 6 is arranged.
Next, the five wire rods 6 are arranged in the horizontal direction while intersecting with the five vertical wire rods 6.
These five horizontal wires 6 are arranged at the same vertical interval as the arrangement interval (W) of the pin pieces 8 of the frame member 4.

Here, the horizontal wire 6 is arranged at the intersection 7 with the vertical wire 6 so that the vertical wire 6 and the horizontal wire 6 alternately cross up and down. That is, when the horizontal wires 6 are arranged, the five vertical wires 6 are arranged alternately so that the first is arranged on the upper side and the second is arranged on the lower side. Also, the horizontal wires 6 adjacent to the upper or lower side are alternately arranged so that the first of the vertical wires 6 is arranged on the lower side and the second is arranged on the upper side, contrary to the above arrangement. (Plain weave).
The wire 6 is flexible and can be elastically deformed within the range in which the wire 6 is disposed (woven).

In this way, for each of the intersecting vertical and horizontal wire rods 6, the vertical wire rods 6 and the horizontal wire rods 6 are alternately arranged at the upper and lower sides at the adjacent intersections 7, thereby reinforcing the wire rods 6 to each other and providing a strong surface material. can get.
In addition, when arrange | positioning the wire 6, in addition to the method of arrange | positioning alternately alternately as mentioned above, there are also the method of arrange | positioning alternately, etc., and it is in the state where balance is generally possible and reinforcement is possible. It is good also as arranging.

In addition, there is a form in which all of the five vertical wires 6 are arranged (not woven) on the lower side (upper side) and all of the five horizontal wires 6 are arranged on the upper side (lower side). Thus, the horizontal wire 6 is assembled in a mesh pattern with respect to the vertical wire 6.
And after arrange | positioning the said 5 horizontal wire rod 6, the frame members 4 and 4 are each arrange | positioned with the pin piece 8 facing inside (wire rod 6 side) at these right and left, respectively, and each pin piece 8 corresponds, respectively. It inserts in the cylindrical hole part 16 of the wire 6 to perform. At this time, an adhesive may be injected between the cylindrical hole portion 16 of the wire 6 and the pin piece 8 to bond them together, and reinforcement such as prevention of disconnection may be performed.

After the arrangement of the left and right frame members 4, 4, the end portions of the respective frame members 4 with the frame members 4, 4 arranged above and below are abutted to form a corner portion 5. And the edge part of each frame material 4 is fixed in each corner | angular part 5 of four places.
In addition, the edge part of each frame material 4 is cut at an angle of 45 degree | times, and both the frame materials 4 cross at right angle (without overlapping) in the state which match | combined edge parts. And the four corner | angular parts 5 where the edge parts of each frame material cross are joined by welding (aluminum welding). Thereby, the frame 3 in which the upper and lower frame members 4 and 4 and the left and right frame members 4 and 4 are formed around is formed.
And the mesh-shaped ceiling material 2 by which the wire 6 was assembled in the shape of a vertical and horizontal mesh inside is obtained.

  In addition to the method of joining the four corners 5 where the frame members 4 intersect with each other by welding, the frame members 4 can be fixed with fastening members such as bolts and nuts or screws. At this time, the end of each frame member 4 is left as it is (not cut at 45 degrees). In this case, the horizontal plate portions 14 at the ends of the frame members 4 intersect at right angles in a state where they overlap each other. And this overlapped part is fastened with the said fastening tool, and the four corner | angular parts 5 which each frame material 4 crosses are fixed.

  Although the work of welding the corner 5 is not easy at the site, according to the method of fixing with the fastening tool, the work is simple at the site. For this reason, the mesh-like ceiling material 2 having a size that meets the needs of the site can be easily assembled at the site.

Here, the intersection 7 where the vertical wire 6 and the horizontal wire 6 intersect with each other is left as it is (not joined).
Here, when the vibration of the ceiling or the like is predicted due to the environment around the ceiling or the like, there is a possibility that the intersection 7 between the wires 6 of the mesh ceiling material 2 may be squeezed or misaligned.
For this reason, in order to reinforce the intersection 7 of the said wire rods 6, the intersection 7 is tied up and fixed using the binding band 20 as the fixing tool 20. FIG.
In addition, it does not interfere even if it joins the location where wire 6 cross | intersects by adhesion | attachment etc. for reinforcement.

FIG. 4 shows the binding band 20. The binding band 20 includes a binding portion 22 in which a linear member 21 is formed in an annular shape, a holding fitting 24 for holding a state in which a target object (wire 6 in this case) is bound by the binding portion 22, and the holding fitting 24. It consists of the site | part which extended the linear material 21 ahead, and the annular | circular shaped fastening part 26 attached to the edge part of this linear material 21 ahead. The said linear material 21 consists of metal materials, such as a wire, or a synthetic fat material.
The said binding part 22 winds and binds the intersection 7 of the vertical and horizontal wires 6, and fixes both wires 6.

  The holding metal 24 bundles and holds the two linear members 21. For this reason, one end part of the linear member 21 of the bundling portion 22 is held by the holding metal fitting 24 with the intersection 7 between the wires 6 hidden therein, and the intersection 7 is further bound by the linear member 21, A part of the material 21 is held at the same time. Then, after pulling the fastening portion 26 and the like to tie the two wires 6 at the intersection 7, the holding metal 24 is crushed with a tool or the like to hold the wire 21 so as not to loosen.

About the binding band 20, several places of the intersection 7 of the wire materials 6 of the mesh-like ceiling material 2 are tied up with this binding band 20, and the intersection 7 is fixed, and a squeak etc. are prevented. In particular, it is effective to attach the binding band 20 to the intersection 7 in the center part away from the frame member 4 and the intersection 7 in the vicinity of the center part among the intersections 7 of the wire members 6 in the mesh ceiling material 2. is there.
In addition, a fixture or the like may be used as the fixture 20. For example, a U-shaped or S-shaped metal fitting is used as the fixing metal fitting, which is attached to the intersection 7 in an oblique manner, and the metal rods 6 at the intersection 7 are fixed by tightening the metal fitting with a tool.

Next, a ceiling structure using the mesh ceiling material 2 and a ceiling construction method will be described.
The mesh-like ceiling material 2 is attached using a suspension bolt suspended from a beam or the like as a ceiling base material, a hanger attached to a lower portion of the suspension bolt, and a holding bar material supported by the hanger.
As the holding bar material, a long material having a cross-sectional hat shape or an inverted T shape is used. These holding bar materials use a light metal such as an aluminum material.

  Each of the holding bar members is provided with a holding portion protruding in a flange shape from the left and right sides. Then, the holding bar material is supported by a hanger, the holding bar material is arranged in four directions, and is assembled into a square shape having the same size as the mesh ceiling material 2. That is, the part of the frame material 4 of the mesh-like ceiling material 2 is placed and held on the upper part of each holding part inside each holding bar member assembled in a square shape.

  Further, after the mesh ceiling material 2 is laid on the ceiling, a fall prevention wire is attached to prevent the mesh ceiling material 2 from falling. For example, one end of the fall prevention wire is attached to the support portion 18 of the frame member 4 of the mesh-like ceiling material 2, and the other end is attached to a suspension bolt or the like of the ceiling base material. Thereby, the mesh-like ceiling material 2 is prevented from falling. Here, there are two supporting portions 18 in the vicinity of the corners 5 at the ends of the left and right frame members 4 of the mesh ceiling material 2.

  Therefore, according to the above embodiment, the wire is inserted into the pin piece and simply assembled by fixing the corners of the frame members, so that it is easy to manufacture, excellent in workability, and lightweight and workable. In addition, the ceiling surface is decorated and contributes to the beautification of the ceiling.
