Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a crimped wire mesh formwork for a method of reinforcing a slope, and more specifically, when forming a wire mesh form with a crimped wire mesh formed by intersecting a vertical line and a horizontal line bent in a wave form. Make sure that the upper cut edge does not catch on the worker's clothing or damage the hose that blows the solidified material into the formwork, etc. The present invention relates to a crimp-wire-meshed mold for forming a legal form, in which the height of the upper edge of the mold can be easily adjusted.

[0002]

[Prior art]

 There is a greening method that reinforces the slope by constructing a frame with a concrete arrow or the like in a planar arrow grid and spraying artificial soil on the lattice to reinforce the slope and green the slope. . This frame includes a wire mesh formwork that functions as a formwork, a reinforcing bar spacer that holds the posture while facing the wire mesh formwork, a reinforcing bar that is integrated with the spacer and passes through vertically, and a star that surrounds the reinforcing bar. It is formed by using a steel cage assembled with a wrapping bar.

[0003] Referring to FIG. 8, in order to form a normal frame 2 on a side surface 1, if the cross-sectional shape of the normal frame is rectangular, the wire mesh frames 3, 3 are in a vertical position. Are positioned so that they face each other in an inclined posture. The posture of the wire netting form is maintained by a reinforcing bar spacer (see reference numeral 9 in FIG. 11 to be described later), and a reinforcing bar cage (see reference numeral 4 in the drawing) is inserted between the wire netting frames to form a mold. Generally, mortar or concrete, especially low slump solidification material, is sprayed into the frame to form a high strength legal frame.

If the solidified material continues to be sprayed, the solidified material is extruded or swells from the mesh of the wire mesh formwork. However, since the solidified material has a low slump, it hardly flows or drips. If the top of the wire mesh form is supplied to fill it, a trowel is applied to the entire surface. When the solidified material that protrudes from the mesh or swells out of the mesh by carrying a trowel is leveled, the wire mesh form hides from the surface, and a smooth surface is obtained by stretching the solidified material. Since the wire mesh form is buried in the solidified material, it is possible to save time and effort for collecting the metal formwork.

[0005] By the way, a crimped wire mesh is used as a wire mesh formwork for forming a legal frame by using a vertical line and a horizontal line which are bent into a waveform and simply intersecting the crimped portion at a crimp portion. This is because the shape retention of the wire net can be sufficiently ensured without applying the heat treatment. That is, if the vertical lines slightly protrude upward and downward from the horizontal lines at the upper and lower ends, and the horizontal lines also slightly protrude right and left from the vertical lines at the right and left ends, the wire mesh will not break apart. Maintain planarity.

When this is used as a formwork, the wire mesh is successively added in the longitudinal direction, so that there is no particular problem even if the horizontal lines protrude from the vertical lines at the right and left ends. The lower end of the vertical line is close to the ground and downward, so there is no need to pay special attention to this. However, the upper end of the vertical line will protrude as if the cut was directly toward the heaven, which could be damaged if the worker's clothes were caught or the hose for spraying solidified material was stabbed. Invite the situation.

[0007]

[Problems to be solved by the invention]

 In order to avoid such a problem, there is a formwork for a legal frame having the following configuration described in Japanese Utility Model Laid-Open No. 7-29028. This means that every other vertical line 21 is wound so as to cover the uppermost one horizontal line 6M of the horizontal lines 6 as shown in FIGS. The vertical line 22 is formed by cutting off the portion 22T indicated by the two-dot chain line in FIG. 2B so that the cut line 22t does not reach the uppermost horizontal line 6M even if the cutout 22t is upward.

In this way, as shown in FIG. 9, every other vertical line 21 does not have its cut end 21 t facing upward, so that there is a possibility that it will harm workers and hoses. Lower. Since the other vertical lines 22 do not protrude upward from the uppermost horizontal line 6M, it can be said that there is little harm. In addition, if the bent portion cutout 21t at the upper end of the vertical line 21 is arranged so as to be on the inner surface side of the frame, the bent portion cutout does not exist on the outer surface side, and the bulged bent portion 21k and the sharp cutout 21t, The 22t will not interfere with the operation of the iron.

As can be seen from this description, the other vertical line 22 is not wound around the uppermost horizontal line 6M, as shown by the two-dot chain line in FIG. This is because the bending direction of the bent portion 22k is opposite to the bending direction of every other vertical line 21. That is, as shown in FIG. 10C, the bent portion cuts 21t of every other vertical line 21 or another vertical line are used regardless of which surface is the outer side of the normal frame when functioning as a mold. Since any one of the cutouts 22t of the bent portion 22 is located on the outer surface side, it can be seen that this obstructs the operation of the iron and increases the time required for leveling the surface.

[0010] Therefore, in the above-described prior art structure, in order to make the bent cut end unevenly distributed to only one side, if every other vertical line is wound around the horizontal line, the other vertical line is wound. The line is cut to avoid forming a bend. This cut top is located below the topmost horizontal line, but the cut is facing upwards, so although the incidence is low, it does not mean that it will not snag or damage clothing. Hard to say.

[0011] In order not to leave the concern in other vertical lines, it is not a countermeasure to bend as in the case of every other vertical line so that the cut is not upward. Not possible. However, it is not easy to bend the wire without winding it around the horizontal wire in the wire end treatment process of crimped wire mesh. The reason is that if the tip of the vertical line is bent without grasping the horizontal line, the vertical axis of the vertical line tends to twist when the bending process is pressed, and when the pressure is released, it will move in the direction of the bent part. Variations occur. To prevent this, a special jig is required separately, the number of molding steps is increased, and the structure of the molding machine is required to be complicated.

By the way, the crimped wire mesh can be made of a surface material that does not lose its shape because the crimped vertical and horizontal lines intersect with each other as described above. This means that the surface stiffness is inevitably low at the periphery. The simplest and most effective way to avoid this is to wind the end of a vertical line around a horizontal line and the end of a horizontal line around a vertical line. The longitudinal edge and lower edge of the wire mesh formwork will be buried deep in the solidified material, and will not cause any problems. However, the presence or absence of wrapping around the upper edge of the wire mesh form, which forms the upper ridge of the normal frame, greatly affects the strength of the ridge.

[0013] Nevertheless, when the above-described wire meshes 3, 3 shown in FIG. 9 are installed as shown in FIG. 11, the rigidity at the upper edges 3u, 3u of the formwork is such that all vertical lines have As a matter of course, the result is reduced as compared with the case where the bending portion is provided. In order to secure high rigidity at the upper edge, it is necessary to increase the wire diameter or increase the number of vertical lines having a bent portion, or the weight of the wire mesh form is increased, resulting in an expensive wire mesh. Disadvantages occur.

Incidentally, the vertical line 21 and the horizontal line 22 intersect at intervals of a plurality of crimp portions formed respectively, and the rectangular meshes 3m, 3m formed thereby are shown in FIG. As mentioned above, all have the same size. In addition, with the intention of suppressing excessive bulging of the low-slump material, each mesh can be kept to, for example, about 2 × 3 cm, so that the number of crimps is three and a half on the left and right, and two on the top and bottom. The length is set to half the length.

The attachment of the girder-shaped spacer 9 to such a crimped wire mesh is as shown in FIG. That is, hook portions 9a, 9a are formed at the ends of the spacer 9, and are entangled with, for example, the vertical lines 21, 22 so as to be engaged. The shape is hook-shaped, as indicated by the broken line when viewed from the line XI-XI in the figure, and the amount δ (see also FIG. 13) that can be displaced in the vertical direction is equal to the peak 2 Therefore, if the diameter t _{9 of} the iron wire is 5 mm, it is at most about 15 mm.

By the way, reinforcement 31 In the inside of each vertical stripe 9h as shown in FIG. 12, on the upper part reinforcing bars 31A are lateral stripes 9m _U, under the lower position of the rebar. 31B lateral stripe 9m _L Arranged in. The reinforcing bar is secured with a binding wire 4k (only one portion is shown) at a portion where the vertical bar and the horizontal bar intersect, so that integrity with the crimped wire nets 3L and 3R is provided. On the other hand, since the reinforcing bar 31 has a diameter of 13 mm even if it is thin, it does not easily adapt to some unevenness remaining on the slope. Therefore, there is a slight up-and-down difference between the state of the crimped wire mesh on the slope side and the state of the reinforcing bars extending. However, if the pair of upper and lower hook portions 9a, 9a can move up and down to some extent as shown in the left part of FIG. 13, the crimped wire mesh does not necessarily have to follow the height of the reinforcing bars.

However, at the intersection of the normal frames, that is, at the corners of the lattice, the reinforcing bars intersect as shown in FIG. In this case, one of the reinforcing bars 31A, 31B extending east and west must be located above each of the reinforcing bars 31C, 31D extending north-south. Now, the spacer 9C, 9D and reinforcement 3 1C, upon lashing to 31D, as spacers 9C, hook portion 9a of the lower position of the lateral stripes 9m _L of 9D is shown in the right part in FIG. 13, a mesh even if position in the vertical direction of the lower end of the 3n _7, reinforcement 31A, mesh 3n ₇ spacer 9A was lashing to 31B, the hook portion 9a of the lower position of the lateral stripes 9m _L of 9B are in the position of the same height It will not fit in. That is, the spacer 9A, the lower position of the lateral stripes 9m _L of 9B, via its hook 9 a, so that the lift left and right wire mesh formwork 3L, the 3R simultaneously in the example of the flying height ε only 11 .

As described above, when the upper edge of the wire mesh form extending in the east and west directions at the corners of the normal grid becomes higher than that extending north and south, the blown low slump solidified material is held by the wire mesh form. There will be a difference. Since the wire mesh form is installed in an encircling manner as shown in FIG. 8, the abutting portion of the form 3M and the form 3N has a low slump at the upper edges 3u, 3u whose heights are shifted. The leveling work of the solidified material becomes complicated and requires much time and effort. In other words, the simple operation at the time of hitting the iron is hindered, and the appearance tends to be poor.

The present invention has been made in view of the above-mentioned problem, and an object of the present invention is to improve surface rigidity at an upper edge portion by taking a simple measure when using a crimped wire mesh as a wire mesh formwork. What can be done and the formation of the bent part at the upper end of the vertical line at the upper edge, so that all cuts can be wound on the same side, whether every other vertical line or other vertical lines, and further reinforced It is possible to eliminate the factors that hinder the operation of the iron by preventing the height difference from occurring at the upper edge of the wire mesh formwork that forms the intersection of the streaks, so that the upper end of the vertical line is entangled with the worker's clothes. A method for reinforcing the slope to reduce the possibility of scratching the solidified material supply hose during the solidified material spraying operation and to make the ironing work smoother. Is to provide a crimped wire mesh formwork.

[0020]

[Means for Solving the Problems]

The present invention is a wire mesh form formed by a crimped wire mesh in which a vertical line and a horizontal line bent in a waveform intersect with each other, such that an upper end cut of the vertical line does not protrude above the uppermost horizontal line. It is applied to the crimped wire mesh formwork for forming the legal frame. The characteristic feature is that the uppermost horizontal line 6T of the crimped wire mesh is formed of two pieces 6A and 6B that are vertically overlapped. The vertical lines are all bent in the same direction so that every other vertical line 5A covers only the upper horizontal line 6A of the two upper ends of the wire mesh formwork, so that the cut 5t does not face upward. Is done. The upper end of the other vertical line 5B is bent in the same direction as the vertical line 5A covering the horizontal line of the upper part so that the cut line 5t does not face upward so as to cover only the horizontal line 6B of the lower part of the two. Have been. As shown in FIG. 6, the wire mesh forms 3R and 3L arranged opposite to each other are provided with a girder spacer 9 for maintaining the facing distance and the facing posture. The vertical distances Hm ₃ and Hm ₇ between the horizontal lines 6 and 6 at the portions where the hook portions 9a formed at the left and right end portions are engaged with the vertical lines 5 are the horizontal lines 6 and 6 at the portions where the hook portions are not engaged. 6 is wider than the vertical interval Hm ₄ .

Returning to FIG. 1, the vertical line 5 and the horizontal line 6 intersect the crimp portions 5a and 6b formed at intervals of a plurality of lines, while the uppermost two horizontal lines 6A and 6B As shown in FIG. 3A, adjacent crimp portions 5a formed on every other vertical line 5A ₁ , 5a_TwoShould intersect with the vertical line 5 </ b> A.

[0022]

[Effect of the invention]

 According to the present invention, the crimped wire mesh is formed of two wires whose uppermost horizontal line overlaps up and down, so that the upper edge of the wire mesh form is strengthened, and therefore the shape retaining action of the legal frame is achieved. Is improved. In addition, the development of the predetermined strength at the upper ridge line portion of the legal frame is promoted. The vertical lines are all bent in the same direction so that every other upper end covers only the horizontal line of the upper part of the two lines so that the cut does not face upward. In addition, the upper end of the other vertical line is bent in the same direction as the vertical line covering the horizontal line of the upper part so that the cut end does not face upward so that it covers only the horizontal line of the lower part of the two lines. Therefore, the entire upper end of the vertical line is given by the bent portion, and the protrusion of the cut is suppressed as much as possible. As a result, it is extremely unlikely that the vertical line gets caught in the worker's clothes or penetrates the hose for spraying the solidified material, and the safety of work is greatly improved.

[0023] In forming the bent portion of the vertical line, the horizontal line is always embraced and there is no empty bending, so that the wire is hardly shaken or twisted during the bending, and special A wire mesh form can be manufactured by applying a conventional bending method without introducing a special jig.

In order to maintain the facing distance and facing posture of the facing formwork, a girder-shaped spacer is used. Hook portions formed at the left and right ends of the formwork engage with the vertical lines. The vertical space between the horizontal lines at the portion where the hook portion is not engaged is wider than the vertical space between the horizontal lines at the portion where the hook portion is not engaged. This means that the tolerance of the vertical displacement of the spacer is increased, and therefore, in the wire mesh form adjacent to the L-shape of the wire mesh forms arranged to bend at the intersection of the normal frames, Differences in height due to overlapping reinforcements are more easily absorbed by the displacement of the spacers secured to the reinforcements. The height of the upper edge of the wire mesh form is not shifted as much as possible, so that the ironing operation for forming the outer surface of the legal form is easy, and the appearance of the intersection of the legal form is also distorted. Can be beautiful and inconspicuous.

A vertical line and a horizontal line intersect a plurality of crimp portions formed respectively, whereas two uppermost horizontal lines are adjacent to each other formed in every other vertical line. If it intersects with the vertical line through the clip portion, the horizontal line interval at the uppermost end can be kept to a minimum. Not only in the formation of a bent portion with respect to a horizontal line above one vertical line, but also in the formation of a bent portion with respect to a horizontal line below another vertical line, even for a horizontal line arranged in such proximity. Only the bending allowance is secured, so that the above-described bending can be facilitated, and the uppermost horizontal line can be doubled with a high reinforcing effect.

[0026]

[Embodiment of the invention]

 Hereinafter, the crimped wire mesh formwork for the slope reinforcement frame according to the present invention will be described in detail based on the embodiment. FIG. 8 is a perspective view of the legal frame 2 formed on the slope 1, and the wire mesh frames 3 for shaping the legal frame 2 are constructed by laying a lath (not shown). It is installed on the ground surface. FIG. 1 shows an enlarged view of a part of the wire mesh formwork 3.

The above-mentioned method frame is formed by filling a low slump solidified material such as mortar with increased viscosity between the opposing wire mesh forms, and a reinforcing steel cage 4 (FIG. 2) is embedded. The arrangement is briefly described in the section of the prior art, and the description is omitted here.

The wire mesh form 3 is used to define the shape when constructing a legal framework, and a crimp wire mesh is used for that purpose. This is, as shown in FIG. 1, a vertical line 5 bent in a waveform and a horizontal line 6 also bent in a waveform intersecting at crimp parts 5a, 6a. As is clearly shown in FIGS. 3 (a) and 3 (b), which are enlarged, the upper end cut 5t of the vertical line 5 is processed so as not to protrude above the uppermost horizontal line 6T.

The wire mesh form 3 is a face material having a height of 30 cm and a longitudinal direction of 250 cm, for example. It is leaned against. As shown in FIG. 2, the wire netting frames 3L and 3R are formed of two pieces 6A and 6B in which the uppermost horizontal line 6T vertically overlaps. As can be seen from FIG. 1, the upper ends of every other vertical line 5A, 5A are bent in the same direction so as to cover only the upper horizontal line 6A of the two lines constituting the horizontal line 6T. (See also FIG. 3 (a)). As a result, the cut 5t does not face upward but faces downward or close to it.

The upper end of the other vertical line 5B is bent so as to cover only the lower horizontal line 6B of the two, and in the same direction as the vertical line 5A which covers the upper horizontal line 6A (FIGS. 1 and 3). (B)). Also in this case, care is taken so that the cut 5t does not face upward.

Referring to FIG. 3, the vertical line 5 and the horizontal line 6 intersect a plurality of crimp portions 5a and 6a formed respectively, and as shown in FIG. , uppermost horizontal line 6A, two of 6B is intersect the vertical line through the clinker flop portion 5a _1, 5a ₂ of adjacent formed in vertical lines 5A every other. That is, not only are the uppermost two horizontal lines 6A and 6B arranged closer than the interval between the other horizontal lines 6 and 6, but also the narrow gap 7 is formed after the vertical line 5A crosses the horizontal line 6B. It functions as a passage that gives a minimum width for extending in the direction of forming the bent portion covering 6A. As shown in FIG. 3 (b), the gap 7 also serves as a space for the other vertical line 5B to extend in the direction of forming a bent portion that covers the lower horizontal line 6B.

As described above, forming the uppermost horizontal line 6T with two lines increases the strength of the upper edge portion 3U of the wire netting form frame 3 for the first time. The reinforced upper edge serves to improve the shape retaining action of the legal frame, and also promotes the development of the predetermined strength of the upper ridge 8 (see FIG. 8) of the legal frame. In addition, every other vertical line 5A and the other vertical line 5B can form a bent portion that is wound around one of the uppermost horizontal lines 6A and 6B. In addition, as shown in FIG. _A , 5t_BCan be positioned on the same surface side.

The meaning of the reinforcement by using two horizontal lines 6T at the uppermost end will be described in more detail. As described above, since the crimped wire mesh is employed as the wire mesh formwork 3, the vertical lines and the horizontal lines are assembled in a state where they are engaged at the crimp portion. Despite the net being not subjected to any securing such as welding, its surface rigidity is maintained to some extent.

However, it is preferable that the material can further contribute to the formation of the legal frame as long as it is used as a mold of the legal frame. In this example, unlike the other three sides, only the upper edge 3U in the free state is reinforced, but this greatly contributes to the improvement in the rigidity of the entire wire mesh formwork.

It is not necessary to increase the rigidity of the surface material uniformly over the entire surface. If the rigidity of some part is made higher than that of the other part, the rigidity reaches the interfacial portion. Focusing on the fact that a certain degree of reinforcement as a surface material can be achieved without increasing the wire diameter, increasing the number of wires used, and increasing the arrangement density of the wires, that is, without increasing the rigidity of the entire surface. It is. Of course, since all the vertical lines are wound around the uppermost horizontal line to form a bent portion, the shape retention and bending are further enhanced, and despite the configuration in which only one horizontal line is added. Instead, it produces various derivative effects.

[0036] More specifically, in constructing the legal form, two wire mesh forms 3 and 3 of the same size are prepared. As can be seen from FIG. t _a, so that all 5t _B is facing side of the other wire mesh 3L, other wire mesh mold 3L flexural portion cut 5t _a, all 5t _B is set to be facing side of one of the wire mesh 3R Will be installed.

Meanwhile, in order to maintain the facing distance and facing posture, the wire mesh forms 3R and 3L arranged opposite to each other are provided with a vertical streak 9h and a horizontal streak 9m as shown in FIG. The provided girder spacer 9 is used. In this, hook portions 9a are formed at the left and right ends of the horizontal streak 9m, respectively, and are entangled with one of the vertical lines. The vertical lines facing each other at the position of the spacer may be 5A and 5B, 5A and 5A, and 5B and 5B in the above-mentioned reference numerals. It is mounted at a position suitable for holding the formwork 3.

Incidentally, the hook portion 9a of the spacer needs to be bent so that the hook portion is closed as shown by a broken line in the figure so that the vertical line 5 does not slip out of the bent end portion and come off. In order to avoid the spacer mounting work on site and to simplify the installation work of the wire mesh formwork, a pair of wire mesh forms facing the spacers 9 must be provided at the stage before shipment. Can be installed. Since the hook portion itself is loosely engaged with the vertical line, the hook portion 9a is used as a hinge to change the parallelogram from FIG. 5 (a) to FIG. 5 (b). For example, it is possible to reduce the bulk during transportation by making it appear as if folded.

FIG. 1 is a diagram in which a mesh of a portion where each hook portion of the spacer is attached is widened._ThreeAnd the second mesh from the bottom 3m₇Is the other mesh 3m_i(I = 1,2,4,5,6,8). That is, the vertical interval Hm between the horizontal lines 6 and 6 at the portion where the horizontal line 9m is engaged with the vertical line 5 _Three , Hm₇However, the vertical spacing of the horizontal line at the portion where the hook portion is not engaged with the vertical line, for example, Hm_FourIt is wider than it is.

Specifically, in the meshes 3 m ₃ and 3 m ₇ , the number of crimps on the vertical line 5 is 3.5, which is larger than 2.5 in other meshes. Assuming that the number of peaks on the left and right of one mesh is 3.5, the meshes 3m ₃ and 3m ₇ form a square, but this is not intended. The number of peaks on the left and right may be left as it is, while the number of peaks on the top and bottom may be set to, for example, 4.5 to form a vertically long rectangle. The size of the mesh is appropriately selected depending on the adjustment of the viscosity of the low slump solidified material and the range in which the material can be sprayed.

Of course, the number of meshes in the vertical direction in one metal mesh form varies depending on the height of the form. Therefore, different meshes, such as 3m ₄ and 3m ₁₀ , with which the hook 9a is engaged can be used. However, in any case, in consideration of the use of the girder-shaped spacer 9, it is sufficient that two tall meshes are formed in the vertical direction. It can be said that the vertical interval represents the tolerance of the displacement of the reinforcing bar spacer.

As described above, all the cut portions 5t of the vertical line 5 are located in the space facing the formwork. First, two reinforcing bars are temporarily placed on the lath laid on the entire slope at positions where the slope is to be formed. As shown in FIG. 2, wire mesh forms 3R and 3L to which the reinforcing bar spacer 9 has been previously passed are arranged from above, and the temporarily placed reinforcing bars 31B and 31B are connected to the spacers as shown in the lower part of FIG. lift up to 9, it is lashed to the intersection of I Ritatesuji 9h and horizontal stripes 9m _L in binding wire 4k. Two reinforcement 31A on the spacer 9, 31A are mounted, are also Ru is fastened to the intersection of the vertical line 9h and horizontal stripes 9m _U.

When the four reinforcing bars are surrounded by the stirrup bars 32 as shown in FIG. 2, the reinforcing bar cage 4 is formed between the wire netting frames 3R and 3L. After that, the end of the hose, whose slope is crawled along the road, is raised to the working position, and the worker supports it and sprays low slump solidified material between the formwork. Subsequent work is as described in the section on prior art. The reinforcing bars do not have to be between the vertical bars 9h, 9h as shown in FIG. 6, but may be arranged outside each vertical bar 9h. Also, in some cases, not all four wires are arranged between the upper and lower horizontal streaks.

As can be understood from the above description, since the bent portion is formed at the upper end of each vertical line of the wire mesh form, the cut portion of the wire mesh caught the worker's clothes during the operation. No more piercing the hose. In addition, since the above-mentioned cut portion is not directed outward, it does not hinder the ironing work. The work is smooth and the surface finish is beautiful, and the buried-type wire mesh formwork can be completely covered with concrete or the like. This avoids exposing the wire mesh formwork and avoids the surface layer deterioration of the legal form due to rust.

The vertical lines are all bent in the same direction so that every other upper end covers only the upper horizontal line of the two lines, but the cut ends do not face upward. In addition, the upper end of the other vertical line also covers only the lower horizontal line of the two lines, and is bent in the same direction as the vertical line that covers the upper horizontal line, so that the cut end does not face upward. In this case, the upper ends of all the vertical lines are formed with the bent portions, and the exposure and protrusion of the cut edges are suppressed as much as possible, and work safety is dramatically improved.

In forming the bent portion of the vertical line, the horizontal line is not gripped, that is, it is not bent in an empty state, so that the wire is not later shaken or untwisted, and the processing method and the processing apparatus are used. There is no need to give special consideration to The two uppermost horizontal lines intersect with the vertical lines through the adjacent crimps formed in the vertical lines.As a result, the interval between the horizontal lines around which the vertical lines are wrapped is kept to a minimum, and the degree of reinforcement is increased. Can be saved. In addition, even though two horizontal lines are arranged in close proximity, the bend allowance and the bending space in the formation of the bent portion of every other vertical line and the formation of the bent portions of other vertical lines (gap portion 7 in FIG. 3). ) Can be secured, and the production of the wire mesh formwork becomes smooth.

As described above, since the mesh of the portion where the hook portion of the spacer is engaged is largely secured vertically, the reinforcing bars 31 also intersect at the intersection of the normal frames as shown in FIG. Even so, the vertical displacement tolerance of the spacer is larger than that described in FIG. 13 of the related art section, and therefore, as shown in FIG. It stays at 3m ₃ and 3m ₇ without lifting one formwork.

[0048] Thus, or can leave the upper edge 3U _1, 3 U ₂ in Figure wire mesh formwork adjacent to the L-shaped 4 3R _1, 3L ₂ at the same height, even one wire mesh formwork Even if the surfacing rises, the displacement can be easily absorbed and the levitation amount can be kept as small as possible. The work to smooth the surface of the low-slump solidified material becomes remarkably easy, and there is little occurrence of surface bending or distortion at that part, and the appearance of the intersection of the legal frameworks is improved.

In the above description, the terms “every other vertical line” and “another vertical line” are used, but this does not necessarily mean “every other vertical line”. It is only a typical expression that the vertical line wrapping around the upper horizontal line and the vertical line wrapping around the lower horizontal line only need to be mixed. For example, when the above-mentioned codes are used to illustrate the arrangement in the left-right direction, for example, "5A, 5A, 5B, 5A, 5A, 5B ...", "5A, 5B, 5B, 5A, 5B, 5B ..." or "5A , 5A, 5B, 5B, 5A, 5A, 5B, 5B..., Etc., it is clear that the same effect can be obtained, and is intended to be within the scope of the present invention. However, regardless of the arrangement, it is still required that all the vertical lines have a bent portion, the bend is in the same direction, and the cut is not upward.

Claims (2)

[Utility model registration claims] 1. A wire mesh form formed by a crimp wire mesh in which a vertical line and a horizontal line bent in a waveform intersect,
In a crimped wire mesh forming frame for forming a legal frame in which the upper end cut of the vertical line does not protrude above the uppermost horizontal line, the crimped metal mesh is formed by two lines in which the uppermost horizontal line overlaps vertically. The vertical lines are all bent in the same direction so that every other vertical line covers only the horizontal line of the upper part of the two upper ends of the wire mesh formwork, so that the cut ends do not face upward, The upper end of the vertical line is bent in the same direction as the vertical line covering the horizontal line of the upper portion so that the cut end does not face upward so as to cover only the horizontal line of the lower portion of the two lines. A wire girder spacer arranged to maintain the facing distance and the facing posture is provided on the wire mesh form arranged in a horizontal position, and hook portions formed on the left and right ends of the girder spacer are engaged with the vertical lines. The vertical distance between the horizontal lines Crimp wire mesh formwork for slope reinforcing usage frame, characterized in that is wider than the vertical spacing of the horizontal lines in the portion where parts are not engaged. 2. The vertical line and the horizontal line intersect with a plurality of crimp portions formed at each other, while the uppermost two horizontal lines are formed at the alternate vertical lines. The crimped wire netting formwork for a slope reinforcing method frame according to claim 1, wherein the crisscrossing portion intersects the vertical line through adjacent crimp portions.
