There are cases where vertical parts are combined.

With reference to FIG. 7 (B), the case where the connector 17 connects the three outer frames 12 is demonstrated. In this case, for example, the sagging portion 27 in FIG. 3 exists at the boundary between the leftmost structure 2A in the drawing and the structure 2B in the middle front.
That is, in this case, (1) in the figure, the horizontal portion of the outer frame 12A of the bottom mesh panel 4A of the left structure 2A, the horizontal portion of the outer frame 12A of the bottom mesh panel 4A of the right structure 2B, When connecting the horizontal part of the outer frame 12F of the right mesh panel 4F of the left structure 2A (at the same time, also the horizontal part of the outer frame 12E of the left mesh panel 4E of the right structure 2B in the figure). (2) In the figure, the vertical part of the outer frame 12C of the front wall net panel 4C of the left structure 2A, the vertical part of the outer frame 12C of the front wall bottom net panel 4C of the right structure 2B, the left side in the figure The vertical part of the outer frame 12F of the right mesh panel 4F of the structure 2A (which is also the vertical part of the outer frame 12E of the left mesh panel 4E of the right structure 2B in the figure) may be connected. .

A case where four outer frames 12 are connected will be described with reference to FIG. In this case, for example, the leftmost structure 2A, the frontmost (first row) middle structure 2B, and the second row of the sagging portion 27 in FIG. It exists at the boundary between the leftmost structure 2C and the structure 2D in the middle of the second row.
That is, in this case, the vertical part of the outer frame 12D of the rear wall network panel 4D of the structure 2A (the outer frame 12C of the front wall network panel 4C of the structure 2C), the outside of the rear wall network panel 4D of the structure 2B. The vertical portion of the frame 12D (the outer frame 12C of the front wall network panel 4C of the structure 2D), the outer frame 12F of the right wall network panel 4F of the structure 2A (the outer frame 12E of the left wall network panel 4E of the structure 2B) In some cases, the vertical portion and the vertical portion of the outer frame 12F of the right side wall panel 4F of the structure 2C (outer frame 12E of the left side wall panel 4E of the structure 2D) are connected.

  When the spiral diameter is increased as the number of outer frames 12 to which the connector 17 is connected increases, the spiral diameter is set when the number of outer frames 12 is four, and the number of outer frames 12 is small. In addition, it is possible to avoid a situation where play between the outer frame 12 and the connector 17 becomes excessive.

  With reference to FIG. 8, the connection of the connector 17 to the outer frame 12 will be described. The connector 17 is engaged with the outer frame 12 at a predetermined interval k to connect the outer frame 12. The yarns 22 constituting the net 11 are attached to the outer frame 12 at an angle of 45 ° at a constant interval p. The movement of the connector 17 in the longitudinal direction of the outer frame 12 is restricted by the net 11. The constant interval p may be set to 65 mm to 100 mm, for example. The net may have a structure arranged vertically and horizontally in parallel with the outer frame 12. The net may have a structure in which a fine mesh and a coarse mesh are doubled. In this way, the stuffing stone 21 can be more reliably held in the structure 2 (FIG. 3). The constant interval k may be, for example, 200 mm to 500 mm.

  With reference to FIG. 9A, the shape of the connector 17 will be described. The connector 17 in the figure is formed in a spiral shape slightly less than three turns. The connector 17 is preferably formed in a spiral shape with more than 1 winding and less than 3 windings from the wire. It may be formed in a spiral shape with more than one and a half turns and less than two and a half turns. In this way, attachment to the outer frame 12 (FIG. 7) becomes easier and the structure 2 (FIG. 3) can be formed in a shorter time. When the spiral movement pitch in the central axis direction by one turn of the spiral is p2, and the length in the central axis direction of the whole connector is p1, p2 <p1 <3 × p2. It may be 1.5 × p2 <p1 <2.5 × p2.

Since the length of the connector 17 in the central axis direction is configured in this way, the connector 17 is fixed to the outer frame 12 after filling the entire interior of the structure 2 (FIG. 3) with the filling stone 21 (FIG. 3). When the connecting tool 17 is attached at the interval k (FIG. 8), the connecting tool 17 interferes with the filling stone 21, and when the connecting tool 17 is not attached to the outer frame 12, the attachment position of the connecting tool 17 is interfered with the filling stone 21. It is possible to change to a place where no connection is made, the attachment of the connector 17 becomes easy, the connector 17 can be attached in a short time, and the revetment structure 1 (FIG. 3) can be formed in a short time.
Also, if the pitch p2 is the same as compared to a long connector (for example, approximately the same length as one side of the outer frame 12) in which the spiral is wound many times, it is light and small. It is easy to handle and can improve workability. Moreover, since the length of the connector 17 can be processed uniformly and can be used uniformly on one side of the outer frame 12 having different lengths, the economy and workability can be improved.

The diameter d1 of the wire forming the connector 17 is, for example, 3.2 mm. The material of the connector 17 is, for example, stainless steel (for example, austenitic stainless steel, SUS304 (JIS G 4309)). The connector 17 may be a galvanized iron wire (JIS G 3547), a colored painted galvanized iron wire (JIS G 3547), or a high-strength vinyl chloride coated galvanized iron wire (JIS G 3543). Alternatively, it may be formed from a molten aluminum plated iron wire (JIS G 3544), a zinc / aluminum alloy plated iron wire, or a zinc / aluminum / magnesium alloy plated iron wire using a soft iron wire (JIS G 3505). The plated iron wire may be a rough surface plated iron wire or a smooth surface plated iron wire. The connector 17 may be formed of the same material as the net 11 or the outer frame 12, or may be formed of a different material. The net 11 can be made of an expanded metal, and the material can be stainless steel (for example, SUS436L). When stainless steel is used, the corrosion resistance can be increased.
The diameter of the thread 22 (FIG. 8) constituting the net 11 may be 3.2 mm, which is the same as that of the connector 17.

  As shown in FIG. 9B, the connector 17 may have a structure having engaging portions 18 at both ends. After connecting the connector 17 to the outer frame 12 (FIG. 8), the engaging portions 18 may be engaged with each other. In this way, the connector 17 can be made more difficult to come off.

  As shown in FIG. 10, the connector 19 as a connector for the revetment structure is not formed in a spiral shape but is formed from a metal member formed in a shape forming a part of a C-shaped ring, and is connected to both ends. It is good also as a structure which provided the joint part 20. Since the engaging portions 20 are provided at both ends, if the engaging portion 20 at one end is the first engaging portion, the engaging portion 20 at the other end is the second engaging portion. It is. Since the connector 19 is formed of a member formed in a shape that forms a part of a C-shaped ring, it can be said that the connector 19 has a partial ring portion formed in a partial ring shape. It is desirable that the connector 19 be easily deformed if a force is applied using a hand and that the engaging portion 20 is easily deformed. By the connecting tool 19, the outer frames 12 (FIG. 6) of the mesh panels 4A to F (FIG. 1) can be provided and connected to each other to form the structure 2 (FIG. 1). By engaging the engaging part 20 after engaging the connecting tool 19 with the outer frame 12, the connecting tool 19 becomes more difficult to come off. When the diameter d2 in the state in which the engaging portion 20 of the coupling tool 19 is engaged is sufficiently large and the coupling tool 19 is attached to the outer frame 12, the coupling tool 19 and between the outer frame 12 and the outer frame 12 It is preferable that play is generated between the outer frames 12. In this way, the connector 19 can be smoothly attached to the outer frame 12. According to the present connecting tool 19, it can be attached to the outer frame at regular intervals, the attaching position of the connecting tool 19 can be adjusted as necessary, and a filling stone 21 (FIG. 3) as a filler and the connecting tool. Since the connection tool 19 can be easily attached while avoiding interference with 19, the structure 2 (FIG. 3) can be formed in a short time, and the revetment structure 1 (FIG. 3) can be formed in a short time. Can do. In addition, since it is lighter and smaller than a long coupling tool in which a spiral is wound, it is easy to handle at the site and workability can be improved. Moreover, since it can use uniformly on the one side of the outer frame from which length differs, economical efficiency and workability | operativity can be improved. In addition, the connecting tool 19 can be easily tilted in order to avoid interference with the stuffing stone 21 during mounting, and is easy to mount.

  As shown in FIG. 11, after making the connector 17 into a spiral structure, it is good also as a structure where outer peripheral surfaces contact in the advancing direction of a spiral. Specifically, as shown in (A), a structure in which the spiral advances in the radial direction of the spiral may be used, or as shown in (C), a structure in which the spiral advances in the direction of the central axis of the spiral may be adopted. . If it does in this way, it can be set as a coupling tool with the same wire diameter and high intensity | strength. (B) shows an X1-X1 cross section of (A), and (D) shows a cross section in the central axis direction of (C). Here, the outer peripheral surface refers to the entire surface exposed to the outside and excluding the cut end surface.

Next, with reference to FIGS. 1-3, the construction method of a seawall structure is demonstrated.
Lay the bottom net panel 4A on the revetment. A box-like structure in which the front wall net panel 4C, the left side wall net panel 4E, the right side wall net panel 4F, and the rear wall net panel 4D are laid in a posture perpendicular to the revetment, and the laid net panel has an opening at the top. A preliminary structure in front of the body 2 is formed. Next, another bottom net panel 4A is laid next to the preliminary structure. Next, depending on the installation position of the bottom mesh panel 4A, when installing the bottom mesh panel 4A on the left side in the figure, the front wall mesh panel 4C, the rear wall mesh panel 4D, and the right wall mesh panel 4F are further laid. When the bottom mesh panel 4A is connected to the other bottom mesh panel 4A with the connector 17, or when the bottom mesh panel 4A is installed on the rear side in the figure, the left side wall panel 4E, the right side wall panel 4F, and the rear wall network panel. Further lay 4D. The adjacent outer frames 12 are connected by the connecting member 17 from the place where all the adjacent outer frames 12 are aligned. The portions where the adjacent outer frames 12 are not all aligned are connected by the connector 17 when all the adjacent outer frames 12 are aligned in a subsequent work process.

  When connecting the connector 17 to the outer frame 12, the connector 17 is engaged with the outer frame 12 at regular intervals while rotating the connector 17. By rotating the connector 17 more than the number of turns, the entire outer frame 12 can be disposed inside the connector 17. After all the net panels other than the lid net panel 4B are installed, the stuffing stones 21 are filled into the respective preliminary structures. The padding stone fills the entire interior of the preliminary structure so that it rises from the opening and does not protrude outward from the opening. Next, the lid network panel 4B is laid. At this time, similarly, the adjacent outer frames 4A to F are connected to each other by the connector 17, and the lid network panel 4B is connected to a network panel other than the bottom network panel 4A to finally complete the structure 2. . The connector 17 is attached to the outer frame 12 at regular intervals. However, when the connecting tool 17 interferes with the stuffing stone 21 and cannot be mounted at a fixed interval, the connecting tool 17 can be shifted to a position where interference can be avoided, and the connecting tool 17 can be easily attached. Since it can be attached, the revetment structure 1 can be formed in a short time.

  In the method for constructing the seawall structure, a connector 19 (FIG. 10) may be used instead of the connector 17 (FIG. 9). When the connecting tool 19 is connected to the outer frame 12, the connecting tool 19 is engaged with the outer frame 12 at regular intervals while rotating. Immediately after engaging the connector 19 with the outer frame 12, the engaging portions 20 are engaged with each other. The connecting tool 19 is also attached to the outer frame 12 at regular intervals. Similarly to the connection tool 17 of the connection tool 19, when it cannot be attached at a fixed interval due to interference with the filling stone 21, the connection tool 19 can be shifted to a position where interference can be avoided. Can be easily attached, so that the revetment structure 1 can be formed in a short time.

  When forming the above-mentioned preliminary structure from the bottom mesh panel 4A, the front wall mesh panel 4C, the left wall mesh panel 4E, the right wall mesh panel 4F, and the rear wall mesh panel 4D, the length of one side of the outer frame 12 is set. At the stage of completing the structure 2 by connecting the lid network panel after filling the stuffing stone 21 into the inside of the preliminary structure using a long connecting tool in which the windings are almost equal in number, the connecting tool 17 Alternatively, the connecting tool 19 may be used.

  The revetment structure 1 is composed of the mesh panels 4A to F and is composed of the structure 2 filled with the stuffing stones 21. Therefore, the revetment structure 1 has the effect of suppressing the movement of the earth and sand, the buffering effect of the running water, the wave-dissipating effect, and the purification effect. Since it has water permeability and water permeability, the natural environment can be preserved.

  FIG. 12 is a schematic diagram showing a structure of a revetment structure 31 as a retaining wall structure according to the second embodiment of the present invention, which is constructed by horizontally stacking the net panel structure 2 shown in FIG. It is.

  The structure 2 is filled with stuffing stones 21 as fillers (in the figure, only some of the structures 2 are shown with stuffing stones 21 and others are omitted). The structure 2 is configured by connecting adjacent outer frames (not shown in FIG. 12) with a connector (not shown in FIG. 12).

  FIG. 13 is a schematic diagram for explaining the positional relationship between the lower structure 2L and the upper structure 2M stacked on the lower structure 2L. In the figure, for the sake of explanation, the upper structure 2M is drawn vertically above the lower structure 2L (z direction in the figure). As shown in the figure, the upper structure 2M is laid out by shifting by half the width of the structure in the width direction (x direction), and the length direction (y direction) is laid in an overlapping manner without causing a shift. Yes.

  In the figure, the overlapping state of the outer frames 12 in the width direction will be described (detail of A1 portion). The outer frame 12BL of the lid net panel 4BL of the lower structure 2L, the outer frame 12EL of the left side wall panel 4EL, the outer frame 12AM of the bottom net panel 4AM of the upper structure 2M, and the outside of the left side wall panel 4EM The frame 12EM is an outer frame adjacent to each other, and the connector 17 connects these four outer frames.

  In the figure, the overlapping state of the outer frames in the length direction will be described (details of part A2). The middle frame 13BL of the lower structure 2L, the outer frame 12AM of the bottom mesh panel 4AM of the upper structure 2M, and the outer frame 12CM of the front wall mesh panel 4CM are adjacent to each other, and the connector 17 Connects these three outer frames. Furthermore, the overlapping state of the outer frames in another length direction will be described (detail in A3). The outer frame 12BL of the lid network panel 4BL of the lower structure 2L, the outer frame 12DL of the rear wall network panel 4DL, and the inner frame 13AM of the bottom network panel 4AM of the upper structure 2M are adjacent to each other. The connector 17 connects these three outer frames.

Next, with reference to FIG. 12, FIG. 13, the construction method of a seawall structure is demonstrated.
Lay the bottom net panel 4A on the revetment. A preliminary structure at the bottom of the box-shaped structure 2 in which the front wall network panel 4C, the left wall network panel 4E, and the rear wall network panel 4D are laid in a posture perpendicular to the revetment, and the opening is formed in the upper portion by the laid network panel. Form the body (no right side wall panel 4F at this stage). At this time, the locations where the adjacent outer frames 12 (FIG. 6) are all aligned are connected by the connector 17, and the net panels 4C to E are connected to the bottom net panel 4A. The portions where the adjacent outer frames 12 are not all aligned are connected by the connector 17 when all the adjacent outer frames 12 are aligned in a subsequent work process. The connector 17 is engaged with the outer frame 12 while rotating around an axis (not shown) parallel to the center line of the outer frame.

  Next, in order to form another preliminary structure on the right side of the preliminary structure in the drawing, another bottom net panel 4A is laid. Then, a front wall net panel 4C, a rear wall net panel 4D, and a left side wall net panel 4E (the right side net panel 4F of the adjacent preliminary structure on the left) are laid, and the net panel 4C to the other bottom net panel 4A are laid. E is connected by a connector 17. This process is repeated to form a preliminary structure at the lowermost stage, and then each preliminary structure is filled with a packing stone 21. The stuffing stone 21 is filled in the entire inside of the preliminary structure so that it rises from the opening and does not protrude outward from the opening.

  Next, the lid network panel 4B is connected to each preliminary structure. At this time, similarly, the adjacent outer frames are connected to each other by the connector 17 to connect the lid network panel 4B to the network panel other than the bottom network panel 4A, and finally the lowermost structure 2 is connected. Finalize. The same process is repeated to complete the second and subsequent structures 2 from the bottom. As described above, the upper structure 2 is laid in the width direction by a half of the width of the structure 2 so as to be shifted from the lower structure 2, and the upper structure 2 has a lower length in the length direction. The structure 2 is laid on top of each other without causing any deviation.

  The connector 17 is attached to the outer frame 12 at regular intervals. However, when the connecting tool 17 interferes with the filling stone 21 and cannot be attached at a fixed interval, the connecting tool 17 can be attached to a position where interference can be avoided, and the connecting tool 17 can be easily attached. Therefore, the structure 2 can be formed in a short time and the revetment structure 31 can be formed in a short time.

A connector 33 having a structure as shown in FIGS. 14A to 14E can be used instead of the connector 19 (FIG. 10). FIG. 14A is a front view of the connector 33, and FIG. 14B is a view taken along arrow A in FIG. FIG. 14C is a Q1-Q1 cross section of a partial ring portion 24 to be described later in FIG. FIG. 14D is a Q2-Q2 cross section of the first engaging portion 36 described later in FIG. FIG. 14E is a Q3-Q3 cross section of a second engaging portion 37 described later in FIG.
The connector 33 is manufactured by cutting and bending a wire rod (JIS G 4314 (stainless steel wire for spring) SUS304-WPB diameter 3 mm) having a diameter of 50 mm and a pitch of 6 mm.

  The connector 33 includes a first engagement portion 36 including a substantially semicircular arc shape at one end, a second engagement portion 37 including a substantially semicircular arc shape at the other end, and an oval shape. (Partial ring shape) It consists of a partial ring portion 24 as a connector ring portion, which is a shape in which a portion of the vertical width is 50 ± 2 mm and the horizontal width is about 55 ± 2 mm. Since the connector 33 is manufactured by cutting a coiled wire and bending it, the first engaging portion 36, the second engaging portion 37, and the partial ring portion 24 are formed integrally. The connector 33 may be of a size and weight that can be held with one hand. For example, it is desirable that the dimensions include a part of an ellipse having a vertical width of 30 mm and a horizontal width of 35 mm, and a vertical width of 100 mm and a horizontal width of 105 mm.

  The first engagement portion 36 includes a semi-annular portion 32 as a semi-annular partial ring portion as a partial annular shape, and a straight short-line portion 34 having a length of about 3 mm. The semi-annular portion 32 is formed such that the radius R1 at the inner peripheral portion 32B on the inner side is 5 mm. One end of the semi-annular part 32 is coupled to the partial ring part 24, and the other end is coupled to the short line part 34. A gap is formed between the free end 34A as the tip of the short wire portion 34 and the inner peripheral portion 24B of the partial ring portion 24, and the width of this gap is the diameter of the inner peripheral portion 24B of the semicircular ring portion 32. It is shorter than 10 mm. Therefore, the short line portion 34 is formed in a direction approaching the inner peripheral portion 24 </ b> B of the partial ring portion 24. For this reason, when the 1st engaging part 36 and the 2nd engaging part 37 engage, it is hard to disengage.

  The vicinity of the first engagement portion 36 of the partial ring portion 24 and the first engagement portion 36 are formed on one plane as a first plane. The semi-annular portion 32 is bent in a direction from the coupling portion 35 with the partial ring portion 24 toward the center C of the partial ring portion 24, that is, the semi-annular portion 32 is bent on the one plane. The partial ring portion 24 is configured not to jump out in the direction of the substantially central axis L1 (passing through the center C). Since the 1st engaging part 36 is comprised in this way, it can prevent that 34 A of free ends hurt the person who handles the connector 33. FIG.

  The second engagement portion 37 includes a semi-annular portion 28 as a semi-annular partial ring portion as a partial annular shape, and a short line portion 29 as a tip portion having a linear shape having a length of about 3 mm. Become. The semi-annular portion 28 has a radius R2 of 5 mm at the inner peripheral portion 28B on the inner side. One end of the semi-annular portion 28 is coupled to the partial ring portion 24, and the other end is coupled to the short line portion 29. A gap is formed between the free end 29A of the short wire portion 29 and the inner peripheral portion 24B of the partial ring portion 24, and the width of this gap is formed to be shorter than the diameter of 10 mm at the inner peripheral portion 28B of the semicircular ring portion 28. ing. Therefore, the short wire portion 29 is formed in a direction approaching the side peripheral portion 24 </ b> C of the partial ring portion 24. For this reason, when the 1st engaging part 36 and the 2nd engaging part 37 engage, it is hard to disengage.

  The semi-annular portion 28 is bent in a direction parallel to the central axis L1 of the partial ring portion 24 from the coupling portion 30 with the partial ring portion 24, and the radial direction of the partial ring portion 24 (direction perpendicular to the central axis L1). It is configured not to jump out greatly. Further, the short line portion 29 that is the tip portion of the second engagement portion 37 is formed in a direction substantially along the partial ring portion 24. Since the 2nd engaging part 37 is comprised in this way, it can prevent that the free end 29A of the short wire | line part 29 hurts the person who handles the coupling tool 33. FIG.

  The second engaging portion 37 is formed on one plane as a second plane substantially parallel to the central axis L1, and includes the one plane as the first plane and the one plane as the second plane. Intersect at right angles to each other. Therefore, the first engagement portion 36 and the second engagement portion 37 can be easily engaged. In addition, instead of the above-described partial ring portion, the connector has a ring portion formed in, for example, a spiral shape exceeding one turn, a two-turn spiral shape, a spiral shape greater than two turns and less than three turns, and The first engaging portion and the second engaging portion may be included.

  FIGS. 15 and 16 show an engagement tool 41 for connecting the connector 33 shown in FIG. FIG. 15A is a front view of the engaging tool 41, FIG. 15B is a view taken along an arrow X in FIG. 15A (only a first part 42 described later is shown), and FIG. ) In the direction of arrow Y (only the second component 43 described later is shown). FIG. 16 is a rear view of the engagement tool 41.

Hereinafter, the configuration of the engagement tool 41 will be described with reference to FIGS. 15 and 16. The engagement tool 41 is developed as a dedicated tool for engaging the coupler 33.
The engagement tool 41 includes a first part 42 and a second part 43. The first component 42 includes a first component main body 42 </ b> A, a support component 55, a contact plate component 54, and a side plate 65. The second component 43 includes a second component main body 43A. The first component main body 42A is manufactured by processing a long and thin plate-shaped material, and the first holding portion 44 in which the through hole 46 through which the finger of the hand passes is processed is engaged with the connector 33. It has a tip 45 as a first holding part, and a through hole 47 is formed slightly from the tip 45 from the center. Similarly, the second component main body 43A is manufactured by processing a long and thin plate-like material to form a second grip portion 48 in which a through hole 50 for passing a finger of the hand is processed, and further, the connection tool 33 is engaged. It has the front-end | tip part 49 as a 2nd holding part for combining. In the second component main body 43A, a through hole 51 is formed slightly from the front end portion 49 from the center.

  A plate-shaped backing plate component 54 and a plate-shaped support component 55 are attached to the side surface 53 of the first component main body 42A on the second component main body 43A side. The support component 55 is disposed between the first component main body 42 </ b> A and the plate-like side plate 65. The thickness of the support part 55 is equal to the diameter of the connector material. A through hole 56 that is co-opened with the through hole 47 is formed in the contact plate component 54. The thickness of the contact plate component 54 is equal to the diameter of the material of the connector, and the contact plate component 54 secures a gap in which the connector 33 can be disposed between the first component body 42A and the second component body 43A. It is configured to The first part 42 and the second part 43 are coupled by a stop shaft 57 as a connecting part so as to be rotatable about the stop shaft 57. The stop shaft 57 passes through the through hole 47, the through hole 56, and the through hole 51. Thus, the engaging tool 41 passes, for example, the index finger as the first finger and the middle finger as the first finger through the through hole 46 and the thumb as the second finger through the through hole 50. By moving the finger passed through, the first part 42 and the second part 43 are rotated around the stop shaft 57, and the first part 42 and the second part 43 are similar to a heel. You can make it move. The support component 55 has an arc-shaped portion 55A including a portion formed in the same arc shape as the arc shape of the inner peripheral portion 24B of the partial ring portion 24 of the connector 33, and a partial circle is formed at the end of the arc-shaped portion 55A. An annular groove 55B is formed. The support component 55 further has an end face 64 that is formed flush with an end face 58 described later. As for the rotation angle of the first part 42 and the second part 43, the angle when it is most open is limited as described later, and the angle when it is most closed is simultaneously in the through hole 46 and the through hole 50. The angle at which you can put your finger is limited.

  An end face 58 is formed on the tip 45 of the first component main body 42A on the side facing the second component main body 43A in the drawing. The leading end 49 of the second component main body 43A bites into the end surface 60 on the side facing the first component main body 42A in the figure, forming a U groove 61. By forming the U groove 61, the leading end 49 In addition, a first protrusion 62 and a second protrusion 63 are formed. The surface of the U groove 61 is a U groove surface 61A as the fifth contact portion. The first protrusion 62 is farther from the through hole 51, and the second protrusion 63 is closer to the through hole 51.

  The thickness of the first component main body 42A and the second component main body 43A is preferably larger than the diameter of the wire rod of the connector 33, and the thickness of the support component 55 is the same as that of the backing plate component 54. It may be the same as the diameter of the wire rod of the tool 33. If it does in this way, a connecting tool can be pinched | interposed with a 1st component main body and a side plate, and holding | maintenance of the connecting tool 33 by the engagement tool 41 can be ensured.

Next, a method for engaging the coupler 33 with the engagement tool 41 will be described.
In FIG. 15, one hand, for example, the index finger and the middle finger of the right hand is passed through the through hole 46 of the first grip portion 44 of the first component body 42A, and the second grip portion 48 of the second component body 43A. Spread the index / middle finger and thumb so that the first part 42 and the second part 43 open at the maximum angle through the right thumb through the through-hole 50 of the right hand, and pick up the connector 33 with the left hand. Attach to the tool 41. The maximum angle of the first component 42 and the second component 43 is limited to an angle at which the connector 33 can be attached as follows.
The first engaging portion 36 of the connector 33 is attached to the distal end portion 45 of the first component main body 42A. At this time, the free end 34 </ b> A of the connector 33 comes into contact with the end surface 64 (first contact portion) of the engagement tool 41, and the inner peripheral portion 24 </ b> B of the partial ring portion 24 of the connector 33 is The peripheral part 24C of the partial ring part 24 comes into contact with the side surface 65A of the side plate 65 (sixth contact part), and falls into and comes into contact with the groove 55B (second contact part) of the indicating component 55. The side peripheral portion 24D as the first side peripheral portion is in contact with the side surface 45A (third contact portion) (the side surface 45A on the second component main body 43A side) of the tip portion 45, and the partial ring portion 24 However, the connector 33 is attached so that it may be pinched | interposed into the side plate 65 and the front-end | tip part 45. FIG. Since the partial ring portion 24 is sandwiched between the side plate 65 and the distal end portion 45 and the connecting tool 33 is attached, the connecting tool 33 can be smoothly attached to the engaging tool 41. Can be held more securely.
Furthermore, the angle when the first part 42 and the second part 43 are most opened by rotation is the second side circumference of the semi-annular part 32 of the first engaging part 36 of the connector 33. The side peripheral portion 32 </ b> C as a portion is limited to contact the side surface 63 </ b> A (side surface on the first component main body 42 </ b> A side) (fourth contact portion) of the second protrusion 63. The side peripheral portion 32C is on the opposite side of the side peripheral portion 24D in the direction of the central axis L1 (FIG. 14) of the connector 33. The side peripheral portion 24D is located on the opposite side of the connector 33 to the central axis L1 direction with respect to the side peripheral portion 24C.

The second engaging portion 37 of the connector 33 is attached to the distal end portion 49 of the second component main body 43A. The semi-annular portion 28 of the connector 33 enters the U-groove 61 of the tip 49 of the second component main body 43A, and the side peripheral portion 28C of the semi-annular portion 28 is a U-groove surface 61A (fifth contact portion). The connector 33 is attached so as to come into contact with. When attached in this way, the connector 33 and the engagement tool 41 can be arranged so as to form a substantially flat surface.
As described above, (1) the second part 43 of the engagement tool 41 (the side surface 63A of the second protrusion 63 of the tip 49) is connected to the first engagement part 36 (semi-annular ring) of the connector 33. The engagement tool 41 restrains the movement of the coupler 33 in the direction of the central axis L1 (FIG. 14B) of the coupler 33, and (2) the engagement tool. 41, the first part 42 (groove 55B of the support part 55) is brought into contact with the partial ring part 24 (inner peripheral part 24B) of the connector 33, and the first part 42 and the second part of the engagement tool 41 are contacted. Rotation torque is applied so that the angle formed by 43 is reduced, and the engagement tool 41 presses the connector 33 in a direction along a plane perpendicular to the central axis L1. (3) 1 part 42 (side surface 45A of the tip 45) is brought into contact with the partial ring portion 24 (side circumferential portion 24D) of the connector 33, and the engaging tool 41 is connected to the connector 33 (1). The movement in the direction of the central axis L1 opposite to the direction of the solid central axis L1 is restricted, and the side plate 65 (side surface 65A) of the engagement tool is brought into contact with the partial annular portion 24 (side peripheral portion 24C) of the connector 33, The engaging tool 41 restrains the movement of the coupling tool 33 in the same direction of the central axis L1 as the direction of the central axis L1 described in (1), and (4) the second part 43 of the engaging tool 41 (the tip 49). The U-groove surface 61A) of the U-groove 61 is brought into contact with the second engaging portion 37 of the coupler 33 (the side peripheral portion 28C of the semi-annular portion 28), and similarly, a rotating torque is applied to the engaging tool. 41 pushes the coupler 33 in a direction along a plane perpendicular to the central axis L1, and the coupler 33 can be held by the engaging tool 41. Further, (5) the first part 42 (end surface 64 of the support part 55) of the engagement tool 41 is brought into contact with the first engagement part 36 (the free end 43A of the tip part 43) of the connector 33, and the engagement tool 41 is engaged. The joint tool 41 restrains the movement of the coupler 33 in the direction along the plane perpendicular to the central axis L <b> 1, and the coupler 33 can be held by the engagement tool 41. Note that the turning torque is applied to the engaging tool not as a separate operation but as a single operation.
The second part 43 of the engagement tool 41 (the U groove surface 61A of the U groove 61 of the distal end portion 49) is used as the second engagement portion 37 of the connector 33 (the inner peripheral portion 28B of the semicircular ring portion 28). It is good also as a combination of the structure which is made to contact and similarly applies a rotational torque, and the engagement tool 41 presses the connection tool 33 in the direction along a surface orthogonal to the central axis L1.
As described above, since the connecting tool 33 can be attached to the distal end portion 45 of the first component main body 42A and the distal end portion 49 of the second component main body 43A, the connecting tool 33 is securely attached to the engaging tool 41. It is possible to prevent the connector 33 from easily falling off the engagement tool 41.

  Next, the first component 42 and the second component 43 are slowly rotated so that the angle formed by the first component 42 and the second component 43 decreases. At this time, a turning torque is applied in a direction in which the angle decreases by a hand putting a finger in the through holes 46 and 50. Further, when rotated, the outer peripheral portion 32A of the semi-annular portion 32 of the first engaging portion 36 and the outer peripheral portion 28A of the semi-annular portion 28 of the second engaging portion 37 approach each other, and both are in contact with each other. Touch.

  Further, when the rotational torque is increased and rotated, the outer peripheral portion 32A of the semi-annular portion 32 moves on the outer peripheral portion 28A of the semi-annular portion 28 so as to slide in the direction toward the short line portion 29. At this time, the first engaging portion 36 and the second engaging portion 37 are pushed away from each other, and the connecting member 33 is elastically deformed. At this time, the side circumferential portion 32C of the semi-annular portion 32 of the first engagement portion 36 is separated from the side surface 63A of the second protrusion 63, and the free end 34A of the first engagement portion 36 is the end surface 64. To slide to the end face 58 (equal to the end face 64). When the semicircular ring portion 32 is further rotated and reaches the free end 29A of the short wire portion 29, the partial annular portion 32 passes through the gap between the free end 29A and the inner peripheral portion 24B of the partial ring portion 24. By the passage of the partial annular portion 32, the action of the force by the engagement tool 41 on the first engagement portion 36 and the second engagement portion 37 is stopped, and the elastic deformation of the coupler 33 is partially released. Then, the disengagement between the first engagement portion 36 and the second engagement portion 37 is released, and the semi-annular portion 32 moves to the inner peripheral portion 28B that is inside the one semi-annular portion 28. The first engaging portion 36 and the second engaging portion 37 engage with each other.

  In this case, as described above, the outer peripheral portion 32A of the semi-annular portion 32 of the first engaging portion 36 and the outer peripheral portion 28A of the semi-annular portion 28 of the second engaging portion 37 approach each other, The distance from the position where both contacted to the free end 29A of the short line portion 29, that is, the first engagement portion 36 contacts the second engagement portion 37 and then the second engagement portion 37 is contacted. The distance traveled until the contact is removed is the predetermined distance of the present invention.

  17A and 17B show a state where the first engaging portion 36 and the second engaging portion 37 of the coupler 33 are engaged. FIG. 17A corresponds to FIG. 14A, and FIG. 17B is a rear view of FIG. 17A viewed from the opposite side (the back of the drawing). In the process of partially releasing the elastic deformation of the connector 33, the inner peripheral portion 32B of the semi-annular portion 32 and the inner peripheral portion 28B of the semi-annular portion 28 are in contact with each other. The connector 33 in this state is in a state of being elastically deformed from the state of the connector 33 shown in FIG. 14, and does not easily disengage the first engagement portion 36 and the second engagement portion 37. It is supposed to be.

  In the engagement tool 14 (FIG. 15), the length from the stop shaft 57 to the center of the through hole 46 of the first gripping portion 46 is approximately twice the length from the stop shaft 57 to the tip portion 45. Furthermore, the length from the stop shaft 57 to the center of the through hole 47 of the second gripping portion 48 is about twice the length from the stop shaft 57 to the tip portion 45. Therefore, the force applied to the gripping portions 44 and 48 is doubled, and the force is applied to the connecting tool 33 from the tip portions 45 and 49 (acting portions), the connecting tool 33 is elastically deformed, and the first engaging portion 36 is applied. And the second engaging portion 37 can be engaged with each other, so that the gripping portions 44 and 48 can be engaged by applying force with one hand. For this reason, it is possible to grasp the connecting tool 33 with one hand and handle the engaging tool 41 with the other hand, thereby facilitating the engaging work of the connecting tool 33 in the field. Further, by increasing the length from the stop shaft 57 to the center of the through holes 46, 50 of the gripping portions 44, 48, the first engaging portion 36 and the second engaging portion 37 can be made with a smaller force. Can be engaged.

  Referring to FIGS. 18 and 19, the connection strength when two mesh panels 4 (FIG. 2) are connected by a connector 33 is connected, and the two mesh panels 4 are connected by a conventional spiral connector 71. A description will be given in comparison with the connection strength at the time. Here, the connection strength means that two test net panels 72 and 73 constituting a part of the net panel 4 are arranged on one vertical plane, and the outside of the test net panels 72 and 73 to which the connecting tools 33 and 71 are attached. This means the magnitude of the load when a downward load is applied to the lower test mesh panel 73 so that the frames 74 and 75 are separated from each other and the connection by the connector 33 is broken.

  FIG. 18 shows the connection strength test facility. In this facility, two test net panels 72 and 73 constituting a part of the net panel 4 (FIG. 2) are connected vertically in the vertical direction by a conventional spiral connector 71. The connector 71 is formed as a coil with a diameter of 5 mm (JIS G 3547) having a diameter (D1) of 50 mm, a winding interval (P1) of 80 mm, and approximately 6.5 turns (the length of the entire coil in the direction of the central axis). Is about 500 mm). The test facility holds the test net panel 72 arranged on the upper side, holds the upper holding frame 78 arranged horizontally, and the test net panel 73 arranged on the lower side, and holds the lower side arranged horizontally. A frame 79 is included. The upper holding frame 78 is fixed to the ground, and the lower holding frame is configured to be able to apply a load to the lower side in the vertical direction and move in the same direction. The lower holding frame 79 maintains a horizontal posture even when a load is applied.

  In the drawing, the test net panel 72 arranged on the upper side is composed of a test outer frame 74 and a test net 76, and the test net panel 73 arranged on the lower side includes a test outer frame 75 and a test net 77. Consists of. The test outer frames 74 and 75 are linear wires having a diameter of 4 mm and a length of about 650 mm. The vertical distance (L3) between the test outer frames 74 and 75 is set to 30 mm before the test is started, that is, before the load is applied. The test nets 76 and 77 are corrugated wires having a diameter of 4 mm, a truss interval (P2) of 99 mm, and an oblique portion length (L2) of 65 mm (the length in the central axis direction is about 650 mm).

  The test net 76 has an upper case 76A (the case means a part having a grade) and every other lower case 76B, and the test net 77 has an upper case 77A and a lower case 77B. Every other. The upper case part and the lower case part are determined by the arrangement of the test nets. When the test nets are rotated 180 degrees around the horizontal central axis, the names are changed.

  A holding plate 80 in which a through hole 82 is formed is attached to the bottom 78B of the upper holding frame 78 of the connection strength test facility perpendicularly to the bottom 78B. The interval between the through holes 82 is set equal to the truss interval (P2) of the test net 76, and the numerical value is 99 mm. The diameter of the through hole 82 is formed larger than the diameter of the test net 76. The test net 76 penetrates the through hole 82 in the upper case portion 76A and holds the test outer frame 74 in the lower case portion 76B. Here, the test net 76 has the test outer frame 74 in the lower case portion 76B. The test outer frame 74 is in contact with the inner peripheral portion of the lower case portion 76B (slightly separated without contact). In the figure, the test net 76 extends from the front side of the test outer frame 74 so as to wrap around the test outer frame 74.

  A holding plate 81 in which a through hole 83 is formed is attached to the upper portion 79A of the lower holding frame 79 of the connection strength test facility perpendicularly to the upper portion 79A. The interval between the through holes 83 is set equal to the truss interval (P2) of the test net 77. The diameter of the through hole 82 is also larger than the diameter of the test net 77. The test net 77 penetrates the through hole 83 in the lower case portion 77B and holds the test outer frame 75 in the upper case portion 77A. Here, the test net 77 is holding the test outer frame 75 in the upper case part 77A. The test outer frame 75 is in contact with the inner peripheral part of the upper case part 77A (when the test case 77 is slightly separated without contact). In the figure, the test net 77 extends from the other side of the test outer frame 75 so as to wrap around the front side of the test outer frame 75.

  Since the winding interval (P1 (80 mm)) of the connector 71 and the truss interval (P2 (99 mm)) of the test nets 76 and 77 are different, the portion where the connector 71 is wound around the test outer frame 74 ( The location where the coupling tool 71 passes in the vicinity of the test outer frame 74) and the location where the test nets 76, 77 are wound around the test outer frame 74, 75 (the coupling tool 71 passes in the vicinity of the test outer frame 74). There are about two places where the same part) matches.

  When a static load is applied to the lower holding frame 79, the connecting tool 71 is pulled up and down by the test outer frames 74 and 75 and the test nets 76 and 77, and the winding diameter of the connecting tool 71 is increased. The load was 6KN when the diameter increased from 50mm to 100mm. At this time, the number of windings of the connecting tool 71 is reduced by the unwinding of the connecting tool 71, the length in the central axis direction is reduced, and the test outer frame 75 cannot maintain a straight line and is bent. The connection between the panel 72 and the test mesh panel 73 cannot be substantially maintained.

  FIG. 19 shows a connection strength test facility to which the connection tool 33 is attached. The difference from FIG. 18 is that the attached connector is the connector 33 shown in FIG. 14 and that the vertical distance (L4) between the test outer frames 74 and 75 before the start of the test is 40 mm.

  The part where the test net 76 is wound around the test outer frame 74 and the part where the test net 77 is wound around the test outer frame 75 are arranged so that the horizontal positions thereof coincide (see FIG. 18 is the same). A total of three connecting tools 33 are attached to every other matching part. In the connector 33, the first engaging portion 36 (FIG. 14) and the second engaging portion 37 (FIG. 14) are engaged. It is also possible to attach the connecting tool 33 to all the corresponding locations. In this way, the connection strength can be increased.

  When a static load is applied to the lower holding frame 79, the connector 33 is pulled in the vertical direction by the test outer frames 74, 75, the interval between the test outer frames 74, 75 is increased, and the shape of the connector 33 is changed. When it changes from a substantially circular shape to a substantially elliptical shape, and the engagement of the first engaging portion 36 (FIG. 14) and the second engaging portion 37 (FIG. 14) of any of the couplers 33 is released. The load was 11 KN.

Therefore, it has been found that the connection tool 33 of the present embodiment is comparable to the conventional spiral connection tool 71 (FIG. 18) and has a connection strength that is equal to or higher than the connection strength.
The coupler 33 can be attached to all the locations where the winding of the test net 76 around the test outer frame 74 coincides with the location where the winding of the test net 77 around the test outer frame 75 coincides. By attaching in this way, the connection strength can be further increased.
Further, the connector 33 of the present embodiment can be used for a mesh panel having a mesh with various truss spacings, and can be selectively attached to a place where the outer frame and the mesh are wound. Strength can be increased.
