[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a metal mesh fixing bracket that holds an installation state by fixing a large number of block bodies, each installed in a predetermined combination state, to a holding metal mesh.
[0002]
[Prior art]
In river revetment work, road or slope construction on roads, etc., a number of natural stones, concrete blocks, artificial stones or support pillars (referred to as block bodies in this specification) are combined in a predetermined state. A construction method is employed in which the installation state is maintained by covering them with a holding wire mesh. In river revetment work, a construction method is also employed in which a mat body constructed by fixing a number of block bodies to a retaining wire mesh with an appropriate combination is spread on the revetment. This construction method is suitable for deformation of the combination of block bodies in response to changes in water pressure and land subsidence, and creates a stronger revetment while maintaining water quality and protecting ecosystems with water permeability. It has the following features.
[0003]
As a conventional method of laying a block body, a plurality of plate materials are dispersed and arranged with respect to an arbitrary mesh, an adhesive is applied to these plate materials and bonded to natural stones, and the wire is sandwiched between natural stones and A construction method that integrates a wire mesh has been proposed (for example, Patent Document 1). In addition, as a method of laying the block body, a method of integrating the anchor net and the block by fixing a fixing plate for pressing the wire of the anchor net to the block with an anchor bolt has been proposed (for example, Patent Document 2). ).
[0004]
In addition, the applicant has made it possible to firmly fix a natural stone to the wire mesh by using a so-called turtle shell woven wire net that is formed by entwining the wire material in a double or triple manner at the knitted portion to form a substantially hexagonal turtle shell pattern as a whole. A natural stone fixing device was provided (Patent Document 3). This prior application natural stone fixing device folds a rectangular metal piece in two, forms a wire mesh gripping portion for fixing the stitch portion of the wire mesh at the bent portion, and attaches a mounting hole to the long piece portion extended from the gripping portion. The formed fixture is used. The natural stone fixing device of the prior application is formed by driving the anchor member into the mounting hole formed in the natural stone corresponding to the mounting hole and screwing the bolt into the anchor member to couple the metal mesh and the natural stone through the fixing bracket. .

[Problems to be solved by the invention]
By the way, the laying method of the block body of patent document 1 mentioned above has the problem that the adhesive agent which joins a board | plate material to a natural stone causes environmental pollution. In addition, such a block body laying method is to assemble the plate material on the natural stone so that both ends are supported on the opposite wire material and located in the mesh space part of the wire mesh, so when a heavy load is applied to the wire material In some cases, the entangled part spreads. In the block laying method, the wire mesh may be deformed or the wire may be twisted, causing the wire to fall off from both ends of the plate, which reduces the bond strength between the wire mesh and natural stone. There was a problem that the combination of the body shifted.
[0006]
Moreover, in the construction method of the block body of patent document 2, it is a construction method which integrates a block and an anchor net via a fixed plate by screwing an anchor bolt into an anchor nut embedded in the block, and does not use an adhesive. Therefore, problems such as the occurrence of environmental pollution do not occur. However, in such a laying method of the block body, since the fixing plate is assembled so as to be supported on the wire rod facing the anchor net, a large load is applied to the wire rod as in the block body laying method of Patent Document 1 described above. In such a case, there is a problem that the entangled portion spreads and the mesh of the anchor net is deformed or the wire rod is twisted, the bond strength between the anchor net and the block is lowered, and the block is displaced.
[0007]
On the other hand, in the prior application natural stone fixing device by the applicant, a large load is applied to the wire because the wire is entangled in a double or triple manner at the binding portion and a turtle shell braided wire mesh having a large tensile strength is used. In this case, the natural stone can be firmly fixed to the wire net without deformation of the net or twisting of the wire. However, such a prior application natural stone fixing device has a problem that the material cost increases because the turtle shell woven wire mesh is somewhat expensive.
[0008]
Therefore, the present invention is inexpensive and enables the wire mesh and the block body to be firmly fixed by suppressing the occurrence of mesh deformation, twisting, etc. by holding the tangled portion of the wire constituting the mesh of the wire mesh. It was proposed for the purpose of providing a simple metal mesh fixture.
[0009]
[Means for Solving the Problems]
The metal mesh fixture according to the present invention that achieves this object is provided with an attachment hole into which an anchor member to be driven into an anchor hole formed in a block body is inserted, and is fitted into the mesh space portion of the holding wire mesh to be fixed by the anchor member. A mounting portion fixed to the block body, and opposite ends of at least one pair of wire rods at opposite diagonal positions constituting the mesh space portion of the wire mesh at both ends in the length direction of the mounting portion. In this way, it is composed of a pair of holding portions that are integrally formed to face each other. In the metal mesh fixture, a wire holding groove in the height direction having an opening shape slightly larger than the outer diameter of the wire is formed in each holding portion.
[0010]
According to the wire mesh fixing metal fitting according to the present invention configured as described above, the attachment portions are fitted in the mesh space portion so that the tangled portions of the wire rods at opposite diagonal positions are fitted in the wire rod holding grooves, respectively. And assembled to a holding wire mesh covering the block body. According to the metal mesh fixing metal fitting, the anchor member is fitted and inserted through the attachment hole provided in the attachment portion, and this anchor member is driven into the anchor hole of the block body communicated with the attachment hole. According to the metal mesh fixing bracket, the attachment portion is fixed to the block body by the anchor member, and each holding portion presses the entangled portion so that the block body and the holding metal mesh are coupled and fixed. According to the wire fixing bracket, the tangled part is held by the wire holding groove formed in the holding part, so that even when a large load is applied to the wire, the mesh of the holding wire mesh is greatly deformed or the wire is twisted. Is suppressed, and the coupling state between the block body and the holding wire mesh is firmly held.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The metal mesh fixture 10 is composed of, for example, a large number of block bodies 1 that are installed in an appropriate combination, for example, in river protection works for rivers or on slopes on roads and development sites, and these block bodies 1 are covered and combined. Used for connection with the holding wire mesh 5 to be held. The metal mesh fixture 10 is also used, for example, for a block mat or the like in which a large number of block bodies 1 are fixed in an appropriate combination state with respect to the holding metal mesh 5 and spread on a seawall or the like.
[0012]
As shown in FIGS. 1 and 3, the block body 1 is formed with an anchor hole 3 for opening the attachment surface 2 and fixing the metal mesh fixing bracket 10 by a drill or the like. In the block body 1, for example, an anchor nut may be embedded in the anchor hole 3. When the block body 1 is artificially formed of concrete or the like, the formation of the anchor hole 3 and the embedding of the anchor nut are performed at the time of molding. Although the details are omitted, a large number of block bodies 1 are installed in an appropriate combination with respect to the installation surface so as to have an appropriate gap between them or to form irregularities.
[0013]
For example, a metal wire such as a zinc-aluminum alloy-plated iron wire, NK (New Callus iron wire) ultra-thick aluminum-plated iron wire, or resin-coated plated iron wire is used as the holding wire mesh 5, as shown in FIG. 1 and FIG. It is entangled in a rectangular or rhombus mesh shape at a predetermined pitch. In the state where the block body 1 is covered, the holding wire mesh 5 has at least one pair of wire binding portions 7 and 8 facing each other at diagonal positions that constitute a predetermined mesh space portion 6 facing the formation region of the anchor hole 3. Is held by the wire mesh fixture 10 as will be described later. Of course, the holding wire mesh 5 may be a tortoise braided wire mesh in which strength is improved by entwining the wire in a double or triple manner at the binding portion of each wire. As will be described later in detail, the mesh shape is sufficiently retained by the wire mesh fixture 10.
[0014]
The metal mesh fixture 10 is formed, for example, by subjecting a rectangular metal plate having rust resistance such as a plated iron plate or stainless steel plate to press processing. The metal mesh fixture 10 includes an attachment portion 11 and a first holding portion 12 and a second holding portion 13 that are integrally connected to both ends of the attachment portion 11 in the longitudinal direction. As shown in FIG. 1 to FIG. 3, the attachment portion 11 has a rectangular plate-like substrate portion 14 having an outer shape that can be fitted in the mesh space portion 6 of the holding wire mesh 5, and opposite ends of the substrate portion 14. In this way, it has a substantially upward U-shape composed of the standing wall portions 15 and 16 that are erected integrally.
[0015]
An attachment hole 17 is formed in the substrate portion 14 in the attachment portion 11. The mounting hole 17 is positioned coaxially with the anchor hole 3 formed in the block body 1 in a state where the mounting portion 11 is fitted in a predetermined mesh space portion 6 of the holding wire mesh 5 as will be described later. The Note that the attachment hole 17 may be formed as a long hole in order to facilitate alignment with the anchor hole 3. In the attachment portion 11, the standing wall portions 15 and 16 are formed such that their heights are slightly larger than the outer diameter of the wire rod of the holding wire mesh 5. Therefore, in the mounting portion 11, the upper end portions of the standing wall portions 15 and 16 protrude from the surface of the holding wire mesh 5 in a state where the substrate portion 14 is fitted in the mesh space portion 6.
[0016]
The first holding portion 12 is formed so as to be integrally bent in the horizontal direction from the upper end of the standing wall portion 15 toward the side, and to face the standing wall portion 15 at the side edge of the ceiling portion 18. It has an inverted L-shape consisting of a holding wall portion 19 that is integrally bent downward. The height of the holding wall portion 19 is slightly larger than the outer diameter of the wire rod of the holding wire mesh 5, and is substantially equal to the standing wall portion 15. In the first holding part 12, a first wire holding groove 20 is formed in the holding wall part 19 from the lower end to the ceiling part 18. The opening width of the first wire holding groove 20 is formed to be substantially equal to the outer shape of the binding portion 7 of the holding wire mesh 5.
[0017]
The second holding part 13 is formed symmetrically with the first holding part 12 and has an inverted L shape composed of the ceiling part 21 and the holding wall part 22 and is integrated along the upper edge of the standing wall part 16. Formed. Also in the second holding portion 13, a second wire holding groove 23 is formed in the holding wall portion 22 so as to face the first wire holding groove 20 on the first holding portion 12 side.
[0018]
In the metal mesh fixture 10, the opposing spacing between the holding wall portion 19 of the first holding portion 12 and the holding wall portion 22 of the second holding portion 13 is an entanglement that forms the mesh space portion 6 of the holding wire mesh 5. The distance between the facing portions 7 and 8 is substantially equal.
[0019]
The metal mesh fixture 10 is fixed to the block body 1 by an anchor unit 25 assembled in the anchor hole 3. As the anchor unit 25, for example, an anchor unit called a so-called all anchor is used. As shown in FIGS. 1 and 3, a steel cylindrical sleeve 26 and an anchor pin fitted in an inner hole 27 of the sleeve 26 are used. 28 and a nut 29 assembled to the mounting portion 11 in a state in which the sleeve 26 is prevented from being detached from the mounting hole 17.
[0020]
The sleeve 26 has an inner hole 27 that gradually decreases in diameter toward the tip and is formed as a bottomed hole, whose outer diameter is substantially equal to the inner diameter of the anchor hole 3 and the mounting hole 17, and whose axial length is the anchor hole 3. It is formed slightly shorter than the depth of. In the sleeve 26, a locking flange portion 30 having a larger diameter than the anchor hole 3 and the mounting hole 17 is formed at a predetermined height position from the tip on the outer peripheral portion. In the sleeve 26, an outer peripheral screw is formed at the outer peripheral portion between the tip and the locking flange portion 30, and a slit 31 is formed at the other end portion.
[0021]
In the anchor unit 25, an anchor pin 28 is assembled in an inner hole 27 of the sleeve 26 in a press-fitted state with a head protruding. The anchor pin 28 has a slightly longer axis than the inner hole 27 of the sleeve 26, and the other end portion of the sleeve 26 is expanded through the slot 31 by being driven into the sleeve 26 as will be described later.
[0022]
The anchor unit 25 is fitted into the anchor hole 3 so that the sleeve 26 is locked to the opening portion by the locking flange portion 30. The sleeve 26 is assembled to the block body 1 with the tip portion where the outer peripheral screw protruding from the anchor hole 3 is formed protruding from the anchor hole 3. Therefore, the anchor unit 25 is disposed within the predetermined mesh space 6 of the holding wire mesh 5 covering the block body 1, and the sleeve 26 assembled with the anchor pins 28 in the press-fitted state is disposed.
[0023]
The anchor unit 25 is not limited to the above-described all anchor, and various anchor members may be used. The anchor unit 25 is integrated with the metal mesh fixture 10 by the nut 29 with the sleeve 26 fitted in the anchor hole 3 in advance. For example, the anchor unit 25 is directly driven into the anchor hole 3 via the mounting hole 17. Also good. Such an anchor unit eliminates the need for the nut 29 and its screwing work, and streamlines the work of attaching the wire mesh fixture 10.
[0024]
The above-described metal mesh fixing metal fitting 10 is assembled to the holding metal mesh 5 that covers a large number of block bodies 1 combined in a predetermined state. The metal mesh fixture 10 makes the holding wall 19 of the first holding part 12 face the binding part 7 and the holding wall part 22 of the second holding part 13 with the binding part 8 with respect to the holding metal mesh 5. The mounting portion 11 is fitted and assembled into the mesh space portion 6 so as to face each other. The tip of the sleeve 26 of the anchor unit 25 penetrates and protrudes from the attachment hole 17 formed in the attachment portion 11 to the wire mesh fixing metal 10.
[0025]
As shown in FIG. 2, the metal mesh fixture 10 has a second wire portion 7 formed in the second holding portion 13 while fitting the binding portion 7 into the first wire holding groove 20 formed in the first holding portion 12. The binding portion 8 is fitted into the wire holding groove 23. The metal mesh fixture 10 is integrated with the anchor unit 25 as shown in FIG. 3 by screwing a nut 29 into the tip of the sleeve 26 protruding from the mounting hole 17. In this state, the metal mesh fixture 10 has the bottom surface of the substrate portion 14 of the attachment portion 11 abutted against the attachment surface 2 of the block body 1, and the holding wall portion 19 of the first holding portion 12 and the second holding portion 13. The holding wall portions 22 are abutted against the mounting surface 2.
[0026]
In the anchor unit 25, the anchor pin 28 is driven into the sleeve 26 with a hammer or the like in a state where the metal mesh fixture 10 is integrated with the sleeve 26. In the anchor unit 25, as the anchor pin 28 is driven, the distal end portion of the sleeve 26 increases in diameter via the slit 31 as shown in FIG. 3, and this expanded diameter portion performs a wedge action in the anchor hole 3. It is firmly fixed to the block body 1. Therefore, the anchor unit 25 firmly fixes the integrated wire mesh fixture 10 to the block body 1.
[0027]
As described above, the metal mesh fixture 10 fixes the holding metal mesh 5 to the block body 1 in a state of being fixed to the block body 1 via the anchor unit 25. That is, in the metal mesh fixing bracket 10, the attachment portion 11 fitted in the mesh space portion 6 is fixed to the block body 1 by the anchor unit 25. As shown in FIG. 4, the metal mesh fixture 10 holds the binding portions 7 and 8 at diagonal positions constituting the mesh space portion 6 by the first holding portion 12 and the second holding portion 13, The holding wire mesh 5 and the block body 1 are integrated.
[0028]
Even when a large tensile force or the like is applied to the wire rod of the holding wire mesh 5, the wire mesh fixing metal fitting 10 sandwiches the entangled portions 7 and 8 between the first wire rod holding groove 20 and the second wire rod holding groove 23, respectively. Since the holding wire mesh 5 is held in a state, it is possible to prevent the mesh of the holding wire mesh 5 from being greatly deformed and the wire material from being twisted. Therefore, the metal mesh fixing bracket 10 prevents the wire rod of the holding wire mesh 5 from coming off and firmly holds the coupled state between the block body 1 and the holding wire mesh 5.
[0029]
The metal mesh fixture 10 has a simple shape including an attachment portion 11, a first holding portion 12, and a second holding portion 13, and is formed at a low cost. The metal mesh fixture 10 is excellent in workability because it is fixed in exactly the same manner as the structure fixed to the block body 1 by a conventional anchor member, and the special holding metal mesh 5 is not used, so the cost is low. It will never grow.
[0030]
By the way, in the above-described wire mesh fixing metal fitting 10, the mounting portion 11 is formed in a substantially upward U shape in which the standing wall portions 15 and 16 are integrally erected so as to face each other from both ends of the substrate portion 14. For example, when a large load that crushes the attachment portion 11 is applied, the standing wall portions 15 and 16 may fall inward. For this purpose, the metal mesh fixture 10 is in a state where the first holding part 12 and the second holding part 13 integrally connected to the attachment part 11 are lifted from the attachment surface 2 of the block body 1. There is a possibility that the binding portions 7 and 8 of the holding wire mesh 5 may fall off from the wire holding groove 20 and the second wire holding groove 23.
[0031]
Therefore, the metal mesh fixing metal fitting 10 is assembled with the reinforcing metal fitting 40 as shown in FIGS. 5 and 6 as required, and the reinforcing metal fitting 40 prevents the standing wall portions 15 and 16 from falling down. The reinforcing metal fitting 40 is also formed by, for example, pressing a rust-proof rectangular metal plate such as a plated steel plate or stainless steel plate, a reinforcing substrate portion 41, and both end portions of the reinforcing substrate portion 41. And a pair of reinforcing standing wall portions 42 and 43 erected integrally so as to face each other.
[0032]
As shown in FIG. 5, the reinforcing bracket 40 has a rectangular plate shape in which the reinforcing substrate portion 41 has an outer shape substantially equal to the substrate portion 14 on the wire mesh fixing bracket 10 side, and an attachment hole 44 is formed. As will be described in detail later, the reinforcing bracket 40 is combined with the metal mesh fixing bracket 10 so that the reinforcing substrate portion 41 is superposed on the substrate portion 14. In this state, the mounting hole 44 communicates with the mounting hole 17 on the substrate portion 14 side. Is done. The attachment hole 44 has substantially the same diameter as the attachment hole 17, and is slightly larger than the outer diameter of the sleeve 26 of the anchor unit 25 and smaller than the nut 29.
[0033]
The reinforcing metal fitting 40 is formed integrally with the reinforcing substrate portion 41 with the reinforcing standing wall portions 42 and 43 having substantially the same height as the standing wall portions 15 and 16 on the wire mesh fixing metal fitting 10 side. Further, the reinforcing metal fitting 40 is formed so that the reinforcing standing wall portions 42 and 43 have a length substantially equal to the interval between the standing wall portions 15 and 16. In other words, the reinforcing metal fitting 40 is formed with an outer shape sufficient for the reinforcing standing wall portions 42 and 43 to close the openings formed on both sides of the attachment portion 11 on the metal mesh fixing metal 10 side.
[0034]
The reinforcing metal fitting 40 configured as described above is directed so that the reinforcing standing wall portions 42 and 43 are respectively positioned corresponding to the opening portions on both sides of the mounting portion 11, and is reinforced as shown in FIG. The board part 41 is assembled on the board part 14 in an overlapping manner. As shown in FIG. 6, the reinforcing metal fitting 40 is assembled to the wire mesh fixing metal fitting 10 by connecting the attachment hole 44 to the attachment hole 17 formed in the attachment portion 11. The reinforcing metal fitting 40 is combined with the metal mesh fixing metal fitting 10 such that the reinforcing standing wall portions 42 and 43 are positioned so that both ends thereof are perpendicular to the inner surfaces of the standing wall portions 15 and 16 and perform a beam action.
[0035]
As described above, the reinforcing mesh 40 is assembled to the metal mesh fixing bracket 10 so that the facing distance between the standing wall portions 15 and 16 is held by the reinforcing standing wall portions 42 and 43. The metal mesh fixing metal fitting 10 is assembled to the holding metal mesh 5 as described above with the reinforcing metal fitting 40 assembled, and is fixed to the block body 1 by the anchor unit 25. The metal mesh fixture 10 is configured so that the holding wall portion 19 of the first holding portion 12 faces the binding portion 7 and the holding wall portion 22 of the second holding portion 13 faces the binding portion 8 so that the mounting portion 11 is attached. Are fitted into the mesh space 6 and assembled.
[0036]
The metal mesh fixing bracket 10 is integrated with the anchor unit 25 by screwing a nut 29 into the tip of the sleeve 26 that passes through the mounting hole 17 formed in the mounting portion 11 and the mounting hole 44 of the reinforcing bracket 40. At this time, the reinforcing metal fitting 40 is fastened together with the nut 29 and integrated with the wire mesh fixing metal fitting 10 and the anchor unit 25. In the metal mesh fixture 10, the base plate part 14 of the attachment part 11, the holding wall part 19 of the first holding part 12, and the holding wall part 22 of the second holding part 13 are abutted against the attachment surface 2 of the block body 1. . The metal mesh fixture 10 is fitted and held in the first wire holding groove 20 of the first holding part 12 by fitting the binding part 7, and is entangled in the second wire holding groove 23 of the second holding part 13. The bald portion 8 is fitted and held.
[0037]
The metal mesh fixture 10 is firmly fixed to the block body 1 via the sleeve 26 when the anchor pin 28 is driven into the integrated sleeve 26. As described above, the reinforcing metal fitting 40 is integrated into the mounting portion 11 by the sleeve 26 and the nut 29 in the metal mesh fixing metal fitting 10, and the four sides of the substrate portion 14 are connected to the standing wall portions 15 and 16 as shown in FIG. The reinforcing standing wall portions 42 and 43 are surrounded and are erected.
[0038]
Even when a large force that crushes the mounting portion 11 is applied to the metal mesh fixing bracket 10, the standing wall portions 15 and 16 and the reinforcing standing wall portions 42 and 43 jointly hold the box shape against this load. This prevents the falling walls 15 and 16 from falling into the inside. Therefore, in the metal mesh fixture 10, the holding wall portion 19 and the second holding portion 13 of the first holding portion 12 connected to the standing wall portions 15 and 16 are abutted against the mounting surface 2 of the block body 1. By holding the state, the binding portions 7 and 8 of the holding wire mesh 5 by the first wire holding groove 20 and the second wire holding groove 23 are firmly held.
[0039]
In the above-described wire mesh fixture 10, the first holding part 12 and the second holding part 13 are connected to the attachment part 11, and the first wire holding groove 20 and the second wire formed on them are formed. The linking portions 7 and 8 at diagonal positions are fitted and held in the holding groove 23, respectively. For example, the holding portion is connected to the four sides of the attachment portion 11 and the mesh of the holding wire mesh 5 is provided. You may make it hold | maintain all the binding parts which comprise the space part 6. FIG.
[0040]
Moreover, although the metal mesh fixing metal fitting 10 showed the example of application to the holding metal mesh 5 which has the rectangular or rhombus mesh space part 6, it is applied also to the holding metal mesh which has mesh space parts, such as a hexagon. The metal mesh fixture 10 has, for example, a hexagonal outer shape as an attachment part fitted into the mesh space part, and a holding part corresponding to two or more ligating parts at different positions on the attachment part. It is formed. Note that the above-described metal mesh fixing metal fitting 10 and reinforcing metal fitting 40 are formed using a metal material having a suitably large thickness in order to prevent dropping due to deformation in accordance with the weight of the block body or the like.
[0041]
