Description

  The present invention relates to a general-purpose installable structure using a turtle shell net.

  The turtle shell wire mesh formed by knitting iron wire or steel wire has a suitable structure that achieves both strength and some flexibility, and is used in various applications. In general, as stipulated in Non-Patent Document 1, a vinyl chloride coated iron wire, a galvanized iron wire, a stainless steel wire or the like is often used. Locally, as shown in FIG. 3, a mesh portion is formed by twisting two lines a plurality of times (twice in the figure). The mesh portions are aligned in the same direction, and the two lines forming the mesh portions are distributed to the left and right hand row lines so as to form an angle of about 120 degrees. Each column line intersects with a column line formed by forming an adjacent mesh portion, and is twisted in the same manner to form a mesh portion. By connecting a pattern that repeats this between two adjacent lines, a hexagonal mesh lined up in the direction of the mesh portion is formed.

  At both ends in both width directions with respect to the direction of the mesh portion, a simple linear ear wire is arranged in the same direction as the direction of the mesh portion, and the mesh portion of the line located at both ends is defined as this ear wire. Twist together to form.

  As a structure utilizing the high strength of this turtle shell metal mesh, for example, in Patent Document 1, a turtle shell metal mesh is wound into a hollow cylindrical shape, stitched with a spiral closed line, the upper part is opened in an annular shape, and the lower part is closed with a purse string. A hanging housing used for stuffing stones has been proposed.

  The purpose of this invention is to create a structure that is easy to install and highly durable using a turtle shell wire mesh.

This device has a frame line of the same shape forming a circular or polygonal ring at each of the upper end and the lower end, and a plurality of support lines are provided between the upper end frame line and the lower end frame line. However, the above-described problems have been solved by a self-supporting turtle shell net structure in which the turtle shell metal mesh is arranged in a hollow column shape along these frame lines and support lines.
While the entire shape is determined by the upper end frame line and the lower end frame line, the lower end frame line side can be put on the floor and become independent by passing the support line between them. A strong structure can be obtained by covering and fixing the outer periphery with a turtle shell metal mesh along the frame line and the support line.

  The frame line itself forms a ring by joining the ends of the line that wrap around the line. In joining the frame line and the support line, for example, the front end of the support line can be wound around the frame line and joined and fixed. On the other hand, when fixing the turtle shell metal mesh, the end can be fixed to the frame line by folding back so as to straddle the upper end frame line and the lower end frame line. Further, as the direction of the turtle shell metal mesh, when the mesh portion due to torsion of the turtle shell metal mesh is directed in the horizontal direction, the fixing at the upper end and the lower end is stabilized. In addition, the fixing in the direction indicated by the mesh portion of the turtle shell metal mesh, that is, the circumferential direction in the structure, is the above-mentioned of the turtle shell wire mesh with respect to the support lines provided at the end portions of the frame line before joining around each other. It is good to wrap around or wind around the said support | pillar line in the middle of a mesh part. Thereafter, the ends of the frame line are joined together, and the strut lines that are folded or wound are brought into close contact with each other.

  Further, when the strength is required, a structure in which an outer frame is provided and integrated may be used. Specifically, a rectangular or substantially rectangular outer frame having sides longer than the maximum width of the upper end frame line and the lower end frame line, and the upper end frame line and the lower end frame for the upper end and the lower end, respectively. An outer peripheral fixed line having the same horizontal height as the line, extending from the outer frame disposed on the upper end side to the upper end frame line, and extending from the outer frame disposed on the lower end side to the lower end frame line. Each shall have one or more.

Further, a plurality of cylindrical self-supporting turtle shell structure may be housed in one outer frame. It is possible to fix a large structure such as a large flower bed. For example, the following structure is provided.
A plurality of the above-mentioned cylindrical self-supporting turtle shell structure having a circular frame line and the same height are arranged so that the frame lines of the self-supporting turtle shell structure adjacent to each other are in contact with each other,
All of the upper end frame line and the lower end frame line have a longer or longer rectangular outer frame, and the same as the upper end frame line and the lower end frame line for the upper end and the lower end, respectively. Each with horizontal height,
An outer peripheral fixed line extending from the outer frame arranged on the upper end side to the upper end frame line and extending from the outer frame arranged on the lower end side to the lower end frame line, for each of the sides or the self-supporting turtle shell structure It becomes a composite self-supporting turtle shell network structure having one or more.

  By this device, it is possible to obtain a highly versatile structure using the flexibility and durability of the turtle shell net. Further, the turtle shell structure according to the present invention is constituted by a combination of wires, and does not require welding at the time of assembly, so that it can be easily disassembled after assembly. It can be easily reassembled and reused after being disassembled, transported and stored. As an application, even in an environment exposed to wind and rain, such as an outdoor installation, a structure having high durability and light weight can be obtained by covering the structure with a sheet.

FIG. 13 is a perspective view showing a state in which a small cylindrical body is incorporated. FIG. 14 is a perspective view showing a state where a large cylinder is incorporated.

  Hereinafter, the present invention will be specifically described with reference to embodiments of the present invention. FIG. 1 shows a perspective view of a first embodiment of a self-supporting turtle shell structure according to the present invention. The basic configuration includes a frame line 21, a support line 22, and a turtle shell network 10 surrounding the periphery. The structure which extracted the frame line 21 and the support | pillar line 22 is shown to the perspective view of Fig.2 (a). The upper end frame line 21a serving as the upper end part and the lower end frame line 21b serving as the lower end part are both circular rings (which will be described later) that are rounded around the line and have the same diameter. The linear support lines 22 are connected and supported between the upper end frame line 21a and the lower end frame line 21b, and a plurality of lines are arranged at equal intervals. The upper and lower ends of the support line 22 are respectively wound around and fixed to the upper end frame line 21a and the lower end frame line 21b (terminal fixing portion 23 in the figure). An example of this situation is shown in the enlarged view of FIG. Moreover, the right angle joint 25 connected with the support | pillar wires 22a and 22b of the edge part for fixing the turtle shell net 10 to each edge part of the frame line 21 is provided. This right angle joint 25 has insertion holes having an inner diameter substantially the same as the diameter of the frame line 21 at angles perpendicular to each other, and can be inserted and fixed, and a tool or the like can be used when necessary. It is preferable that the frame line 21 can be extracted. The ends where the right angle joints 25 and 25 are inserted are brought into contact with each other as shown in FIG. 2 (c), and the strut wires 22a and 22b connected to each other are fixed to each other so that they are not displaced from each other. The structure can keep its shape and can stand on its own.

  The self-supporting turtle shell structure according to this embodiment is attached to the frame body 24 including the frame line 21 and the support line 22 shown in FIG. 2A so that the turtle shell network 10 is wound around from the outside. It becomes. A basic configuration of the turtle shell network 10 used is shown in FIG. A plurality of column lines 11 are arranged, and adjacent column lines 11 and 11 are connected to each other by a linear mesh portion 12 twisted a plurality of times. The mesh part 12 is separated from the mesh part 12 at an angle of about 120 degrees. Next, the adjacent column lines 11 and 11 which are the other combination are twisted together to form the mesh part 12. The length of the straight line portion 13 between the mesh portion 12 and the mesh portion 12 is substantially the same as the length of the mesh portion 12, thereby forming a structure in which substantially regular hexagons are arranged in an orderly manner. However, there may not be a line used for the general turtle shell network 10 to fasten the end portion 15 called an ear wire passing through the portions corresponding to both side end portions in FIG. This is for fixing to the frame 24 instead.

  The above-described frame wire 21, support wire 22, and these wires constituting the turtle shell network 10 are all appropriately selected from iron wires, plated wires, resin-coated wires, etc. according to the required strength and durability. can do.

  A structure for fixing the turtle shell net 10 to the frame body 24 will be described with reference to FIGS. 4 (a) and 4 (b) and FIGS. 5 (a) to 5 (d). When these fixing operations are performed, the frame body 24 including the frame line 21 and the support line 22 forms a plane in a state where the frame line 21 before the wire rod that will become the frame line 21 makes a round is linear. It is easy to work if the tortoise shell net 10 is attached in the state of being. First, the end portion 15 side parallel to the mesh portion 12 is overlapped with the frame line 21, leaving one or more honeycomb structures (FIG. 4A). The surplus portion is folded back so as to wrap around the frame line 21, and the end portion is along the frame line 21 as shown in FIG. In addition, it is good to fix with the plastic fasteners 30 etc. so that the folded-back end part 15 may not bend. As described above, the upper end and the lower end of the turtle shell structure are along the frame line 21 and are covered with the turtle shell network 10 to the ends.

  Furthermore, the structure fixed to the frame 24 in the edge part direction which the mesh part 12 has faced is demonstrated using Fig.5 (a) (b). The end portion is cut with the mesh portion 12 extended, not the single column line 11, and this is left over by 0.5 or more honeycomb structures (FIG. 5A). The remaining portion is folded and fixed so as to wrap the support lines 22a and 22b (FIG. 5B). The fixing with such a structure is performed from both one end of the turtle shell net 10 and the other end that makes a round contact with the frame body 24 (FIG. 5C). In addition, the remaining portion may be wound and fixed as well as being folded.

  The right angle joint attached to the respective ends of the upper end frame line 21a and the lower end frame line 21b by making the frame 24 go around the whole frame line 21 so that the column wires 22a and 22b at the end portions fixed in this way are adjacent to each other. 25 and 25 are abutted with each other as shown in FIG. Adjacent strut wires 22a and 22b are fixed to each other by a fixture 26, so that the frame line 21 is fixed in an annular shape and the turtle shell network 10 is fixed in a cylindrical shape.

  Examples of the fixing tool 26 include a bundling coil that is fixed by being entangled with the mesh portion 12 of the turtle shell network 10 as shown in FIG. For example, it is only necessary to fix the ends with sufficient strength. In any case, the support lines 22a and 22b are adjacently and closely adhered to each other by the fixture 26, so that there is almost no gap where the turtle shell network 10 is not circulated, and the entire structure can be formed into a cylindrical structure.

  With the above structure, the cylindrical body 1 that is a cylindrical turtle shell structure as shown in FIG. 1 can be formed. Since the mesh portion 12 is continuous so as to be parallel to the frame line 21, this structure can be held with a certain degree of flexibility against an external force. The cylindrical body 1 can be self-supported while maintaining its cylindrical shape, and can be used for various purposes by covering it with a sheet, storing an object packed in a bag, or the like. it can.

  In addition, although not shown in figure, it is good also as a prismatic body which made the outer frame into the regular polygon instead of a cylindrical body.

  The above-described cylindrical body 1 (or prismatic body) may be used alone, but stability and durability can be further improved by providing a separate outer frame and integrating it with the outer frame. A structural example of the outer frame 40 is shown in FIG. First, as the outer shape of the outer frame 40, the outer or outer corner lines 41a and 41b having sides longer than the maximum widths of the upper end frame line 21a and the lower end frame line 21b are respectively used for the upper end and the lower end. They have the same horizontal height as the upper end frame line 21a and the lower end frame line 21b. In the embodiment shown in FIG. 6, the outer frame outer lines (41 a, 41 b) at the upper end and the lower end are connected to each other by a linear joint 43 by connecting four wires bent at an angle of 90 degrees. It is formed in a substantially square shape. The straight joint 43 has a cylindrical shape, and has insertion holes at both ends having an inner diameter substantially the same as the diameter of the wire forming the outer frame outer wire 41, similar to the right-angle joint 25. It is preferable that the wire rod is inserted and fixed in the insertion hole, and can be removed when necessary. Among these outer frame outer lines 41, the outer frame outer line on the upper end side is described as the upper end outer frame outer line 41a, and the outer frame outer line on the lower end side is described as the lower end outer frame outer line 41b.

  The upper end side outer frame outer line 41a and the lower end side outer frame outer line 41b are connected by a plurality of outer peripheral fixing lines 42 and their relative positions are fixed. These outer peripheral fixing lines 42 are arranged in contact with the cylindrical body 1 accommodated therein, and at least one, preferably a plurality, are arranged on each side of the outer frame 40 as shown in FIG. 3 per side) and the following positional relationship with respect to the cylindrical body 1. First, it has an upper end horizontal portion 42a extending horizontally from the upper end side outer frame outer line 41a toward the upper end frame line 21a, and a lower end horizontal portion 42b extending from the lower end side outer frame outer line 41b to the lower end frame line 21b. 42a and the lower end horizontal part 42b are connected to each other by an outer frame support part 42c. That is, it is a substantially U-shape opened toward the outside of the outer frame 40. The outer frame support part 42c of the outer periphery fixing line 42 is erected along or in contact with the turtle shell network 10. In addition, about the connection with the upper end horizontal part 42a and the lower end horizontal part 42b, the upper end side outer frame outer line 41a, and the lower end side outer frame outer line 41b, the end part of the outer periphery fixing line 42 is wound around the outer frame outer line 41 and fixed. Yes. This fixing method is the same as that of the terminal fixing portion 23 described above.

  Thus, the self-supporting turtle shell network structure in which the outer frame is attached to the cylindrical body 1 does not necessarily have the configuration as shown in FIG. The outer peripheral fixing line 42 is shorter than that in FIG. 7, that is, the height of the outer frame 40 is shortened, only the upper end of the outer frame is the same height as the upper end frame line 21a of the cylindrical body 1, and the lower end of the outer frame is a cylinder. FIG. 8 shows an embodiment in which the height of the cylindrical body 2 is extended downward so that it protrudes outward in the middle of the body 2. That is, the lower part of the cylindrical body 2 protrudes from the outer frame 40 and can be used in such a form that it is inserted and fixed to other cylindrical parts from above.

  Furthermore, an embodiment in which a cylindrical outer frame 45 having circular outer frame outer lines 46a and 46b is fixed to the cylindrical body 1 is shown in FIG. In order to form the circular outer frame outer lines 46 a and 46 b, both ends of one wire may be connected by the linear joint 43. Further, two or more wires may be connected by the same number of straight joints 43, but in the case of a circular shape, the straight joints 43 can be sufficiently fixed. The position of the upper end side outer frame outer line 46a is outside and upward, that is, obliquely above the upper end frame line 21a of the cylindrical body 1, and the position of the lower end side outer frame outer line 46b is higher than the lower end frame line 21b of the cylindrical body 1. On the outside. The outer peripheral fixed line 47 that connects these is wound around the lower end outer frame outer line 46b at the lower end. The outer peripheral fixing line 47 extending from the end portion is extended horizontally in the center direction (47b portion in the figure) and fixed so as to contact the lower end frame line 21b of the cylindrical body 1. Therefore, it is bent upward and extends to the upper end frame line 21 a along the turtle shell network 10. It extends from the upper end frame line 21a to the outside, not diagonally, but obliquely upward (47a portion in the figure), and is wound around and fixed to the upper end side outer frame outer line 46a. In other words, the lower side of the outer peripheral fixing line 47 is a leg portion, and the cylindrical body 1 is suspended so as not to contact the ground.

  Furthermore, in this embodiment, apart from the outer frame 45, an upper additional frame line 48 having the same diameter as the upper end frame line 21 a of the cylindrical body 1 is arranged directly above the cylindrical body 1, and along the cylindrical body 1. An end portion (50) of the additional support line 49 extending in the vertical direction is wound and fixed.

  In this embodiment, the height of the lower end side outer frame outer line 46b positioned outside the lower end frame line 21b is the same as the height of the lower end frame line 21b, but the lower end side outer frame outer line 46b is lower at the lower end. Embodiment which becomes lower than the frame line 21b may be sufficient.

  By the outer frame and the upper additional frame line as described above, not only the basic shape of the cylindrical body 1 but also a further expanded outer shape can be formed, and the shape can be made according to the installation place and the fixing place. . In addition to the substantially rectangular shape as shown in FIG. 6 and the circular shape as shown in FIG. 9, for example, it is combined with an outer frame having various shapes such as a substantially triangular shape as shown in FIG. 10 and a substantially hexagonal shape as shown in FIG. be able to. If the (substantially) equilateral triangle shape as shown in FIG. 10 is used, a stable outer frame can be configured by connecting the wire 44a bent at 60 degrees with three and three linear joints 43, respectively. If it is a (substantially) regular hexagonal shape, a stable outer frame can be configured by connecting three and three linear joints 43 respectively to the wire rods 44b bent at 120 degrees in the middle. Similarly, in the case of a polygon other than a regular polygon or in the case of a polygon other than these, the bent wire rods can be connected by a straight joint 43 to form an outer frame. The outer frames connected by these linear joints 43 can be easily disassembled, and can be easily disassembled, transported and stored, reassembled and reused.

  Furthermore, it is good also as a composite self-supporting type turtle shell net structure in which a plurality of self-supporting type turtle shell network structures as shown in FIG. 1 are bundled. The example is demonstrated using FIGS. Three small cylinders 5 having the same structure as the cylinder shown in FIG. 1 and one large cylinder 6 having a larger frame line diameter than that are provided. The three small cylinders 5 are arranged so as to be in the most distant positions at an angle of 120 degrees with respect to each other so as to contact the outer periphery of the large cylinder 6. Only the integrated outer frame 51 provided on the outer side is extracted and shown in FIG. The integrated outer frame 51 there is a triangle in which the upper end side outer frame outer line 52a and the lower end side outer frame outer line 52b connect tangents that touch both the two small cylinders 5 and 5, respectively, or rounded corners thereof. It is almost a triangle. Each of the upper end side outer frame outer line 52a and the lower end side outer frame outer line 52b is formed by connecting three wire members 44c bent at 60 degrees with three linear joints 43. Between the upper end side outer frame outer line 52a and the lower end side outer frame outer line 52b, an outer peripheral fixing line 53 having a portion extended inward so as to contact the outer periphery of the small cylindrical body 5 or the large cylindrical body 6 is a side. Several are arranged and fixed every time. The upper end and the lower end of the outer periphery fixing line 53 are extended horizontally, and the end portions are wound and fixed around the upper end side outer frame outer line 52a and the lower end side outer frame outer line 52b.

  The three small cylinders 5 are attached to the inner corners of the integrated outer frame 51 so as to be in contact with each other, and are fixed to the outer peripheral fixing line 53 with a fastener or the like. This state is shown in FIG. Further, the large cylindrical body 6 is fitted into the central space and fixed to the outer peripheral fixing line 53. A perspective view of this state is shown in FIG.
