Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shape in which an expanded metal portion and a flat plate portion are alternately formed, and both portions are alternately bent at a predetermined crossing angle at a boundary between the expanded metal portion and the flat plate portion. The present invention relates to a saw-toothed concavo-convex disc, an applied product thereof, and a method of using the same.

[0002]

2. Description of the Related Art Expanded metal in which a cut line is cut in a steel material and the whole is expanded to form a mesh portion is used for a wide range of applications. In particular, a nominal thickness of 1.2
Expanded metal made from thin steel plate of 6 mm or less has high strength, has many gaps, has good ventilation and transparency, can be mass-produced, and can be obtained at relatively low cost. It is used in a wide range of fields, mainly for civil engineering materials. In addition, the same rust-preventing effect as that obtained by so-called dip-soaking plating has been observed for those made of hot-rolled steel sheets that have been subjected to metal plating centered on zinc at the same time in the rolling process. Expanded metal made of is highly evaluated.

[0003]

Since the thickness of steel used as a raw material of such expanded metal is limited, when high strength is required, flat expanded metal is bent into a repetitive waveform. And so on. If the entire surface of the plate is made of expanded metal, the directions of the steel wires (strands) do not always match, so that it is harder to bend than to bend a flat plate, and more difficult to bend precisely. Further, since the bent edge portion is formed of a thin strand having many gaps, the effect of the rib is small and the effect of forming a waveform cannot be sufficiently obtained.

[0004]

According to the present invention, instead of refracting an expanded metal formed entirely on a mesh portion into a waveform, the expanded metal portion formed into a mesh and a plate portion having no cut line are formed. It is proposed to form a saw-toothed uneven disk in which the expanded metal portion and the plate portion are alternately and repeatedly formed so that the expanded metal portion and the plate portion are alternately bent to the opposite sides at the boundary line. At the same time, it proposes various methods of using such a saw-toothed uneven disk.

[0005] Such a saw-toothed concavo-convex plate may be formed entirely of a single continuous steel plate, or a plate having a predetermined length may be bent at both ends of an expanded metal portion to opposite sides. It is also possible to form a plurality of attached unevenness plates in series with the plate portions bent to the opposite side superimposed on each other.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the case of expanded metal, usually, an original plate having a predetermined width is sent out from a thin steel plate by a machine at a fixed length, and a plurality of blades arranged in parallel at a fixed interval are provided with cuts at a fixed interval. Next, the original plate is fed out for a fixed length, and the blades are shifted by half a phase in the lateral direction, and then a second row of cuts is provided. Next, repeat the operation of returning the blade by half a phase and providing a cut in the third row, forming an opening by pushing and expanding the cut just before the half-phase shift with the cut blade. Thus, a plate which is alternately opened on the entire surface is formed.

In this operation, a predetermined length of the strip
After forming a normal expanded metal by making a cut, the original plate is fed out by a predetermined length without forming a cut to form a plate portion. After forming a plate portion having a predetermined length, an expanded metal portion having a predetermined length is formed by a normal operation of cutting and feeding. By repeating such an operation, a plate portion and an expanded metal portion are alternately formed.

[0008] In normal production, the expanded metal part is pressed down at an angle from top to bottom when cutting and expanding the original sheet. When the plate portion is formed, the original plate is fed out flatly, so that the formed expanded metal portion and the plate portion are produced in a state where they are bent at a certain angle. vice versa,
When moving from the original plate to the expanded metal part, the light is refracted at the opposite angle. Therefore, when the expanded metal part and the plate part are produced alternately, the finished product is alternately bent at a certain angle.

FIG. 1 shows a saw-toothed uneven disk Z of the present invention. The width of the entire board is W, the length of the plate portion A to be left as an original plate is La, and the length of the expanded metal portion B formed in a mesh is Lb. By means of each plate part A
By adjusting the angle of refraction at the connection point J between the and the expanded metal part B, a flat saw-toothed uneven disk Z is formed.

The overall shape of the saw-toothed uneven disk Z can be formed in a flat disk shape having a predetermined thickness as shown in FIG. 1 or a secondary curved surface as shown in FIG. It is also possible to form it on a cylindrical saw-toothed uneven plate Z.

FIG. 3 shows an expanded metal part B.
This is the shape of the mesh b. Mesh width w / feed length l
The width of the score line (strand) s can be arbitrarily selected to some extent, but for the sake of simplicity of description, in the following embodiments, the mesh width w is 75 mm, the length is 125 mm, and the width of the score line s is A description will be given using a product of 4 mm.

The sawtooth-shaped uneven disk formed in this way is a thick disk as a whole, and the plate portion A can act as a rib, so that it can be used as a strong disk. In addition, since a part is a flat plate and a part is a mesh structure, it is possible to make a product utilizing each feature as shown in the following embodiments.

[0013]

Embodiment 1 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 4 shows a saw-toothed uneven plate Z formed by using a long galvanized steel sheet having a thickness of 1.6 mm and a width of 1 meter, and an expanded metal part B having a length of 20 cm and a length of 20 cm. A plate portion A of 20 cm is formed by being repeatedly bent at an included angle of 60 degrees.

As shown in FIG. 5, through-holes a are provided at both edges and the center of the plate portion A, and the through-hole a and the mesh b are shared at both edges and the center in the width direction of the expanded metal portion B, respectively. And three reinforcing bars C penetrating therethrough. Ground rods 1 made of three steel materials, each orthogonal to the lower ends of the three reinforcing rods C
1 to form a surface base 1 of an embankment surface frame having a reverse T-shaped side surface. The length of the ground rod is 2 meters.

The width of the surface table 1 is 1 meter and the height is 50 cm. It is important that the surface of the upper surface of the saw-toothed uneven plate Z facing upward is formed of the expanded metal part B.
A flexible water-permeable sheet 12 having a fine mesh is provided along the back surface of the saw-toothed uneven disk Z with a margin.

The inverted T-shaped surface base 1 thus formed
Is erected along the embankment reference line of the embankment base 20, as shown in FIG. A long geogrid material 21 made of a net having high tensile strength is laid on the ground rod 11 of the surface base 1, and is laid on an embankment base 20 behind the surface base 1.

On the geogrid material 21 behind the surface stand 1, embankment 2 is carried out up to the height of the surface stand. After the embankment is sufficiently compacted, it is used as an embankment base, on which the surface base 1 is installed, a geogrid material is laid, and embankment is performed as in the previous case. When installing the upper surface table, the upper end of the reinforcing rod C of the lower surface table and the grounding rod 11 of the upper surface table
It is desirable to connect with the tip of the. By repeating such operations, a step-type multilayer embankment 2 having a surface base made of a saw-toothed uneven disk and reinforced with a geogrid material is completed.

Although the surface base 1 is pushed forward by the embankment behind it, it is formed by the saw-toothed uneven plate Z, so that it has a very high resistance to horizontal deflection, and the reinforcing rod C penetrates. Because it is reinforced, it is not extruded by the backfill.

The obliquely upward surface of the surface table is constituted by the expanded metal portion B, and the surface plate can be greened by vegetation in the gap of the mesh b. Since a fine mesh water-permeable sheet 12 is attached to the back of the mesh of the surface plate, it is possible to prevent the soil from falling down. Vegetation 13 can be performed through this mesh. Since a small step is formed in the front of the embankment, it is suitable for planting the small tree 14.

In this embodiment, the reinforcing bar is pierced through the saw-toothed uneven plate Z and reinforced and connected to the grounding bar. Instead of the reinforcing bar being pierced and reinforced, as shown in FIG. A steel half-cylindrical object D can be fitted over both edges of the uneven plate Z, or can be reinforced by covering with a steel angle object E as shown in FIG.

[0021]

Embodiment 2 The crossing angle between the plate portion A and the expanded metal portion B and the length of each component can be freely selected, so that the plate portion A at the lower end of the saw-toothed uneven disk Z shown in FIG. As shown in FIG. 9, as shown in FIG. 9, the entire side surface is formed substantially L-shaped, and the ground plate 15 and the surface plate 16, that is, the saw-tooth uneven plate Z are integrally formed. It is also possible.

It is also possible to form the surface stand 1 of the embankment slope itself by forming the included angle between the entire saw-toothed uneven plate Z on the upper side and the ground plate at the lower end so as to match the slope of the embankment slope. Therefore, it is suitable for forming a continuous slope having a constant gradient, and since the surface plate 16 is formed in an uneven shape, the resistance to the earth pressure behind is large, and the cost merit can be greatly expected. .

In this case, if the expanded metal part B at the upper end is also bent horizontally at a narrow angle, it is easy to install the upper surface plate when stacking.

[0024]

Third Embodiment FIG. 10 shows a galvanized steel sheet having a thickness of 1.6 mm and a width of 1.8 m.
This is an example of a saw-tooth uneven plate Z having plate portions A parallel to each other.
A plate portion A having a length of 10 cm is formed in parallel at intervals of 25 cm, and an expanded metal portion B is formed so as to "cross" from one edge of the plate portion to the other edge of the next plate portion.
To form The opening of the expanded metal part is formed large. The width is a saw-tooth uneven plate Z having a height of about 2 meters as a whole, and is suitable for use as a windbreak fence or the like.

As shown in FIG. 11, a method of using as a windbreak fence will be described. A shaft H having a H-shaped cross section made of a thin steel plate is formed. U-shaped concave portions h are formed on both side surfaces. The recesses h of the adjacent shaft member H face each other,
It is driven into the ground at intervals of about 1.8 meters and stands upright.

The fine windproof net 3 made of synthetic resin is
It is stretched on one side of the saw-toothed uneven disk Z as shown in FIG. 10 and is dropped and stood between the concave portions h of the adjacent shaft member H. Even if the opening of the expanded metal mesh is large, the parallel plate portions A formed at intervals of about 20 cm can fix the fine windproof net 3, so that a sufficient effect can be expected.

[0027]

Fourth Embodiment FIG. 12 shows an example in which a "shigara" is formed using the saw-toothed uneven disk Z as shown in the previous embodiment. A 3.2 cm thick, 1 meter wide galvanized steel plate is used to form a saw-toothed uneven plate Z, and an expanded metal portion B having a width of 30 cm and a plate portion A having a width of 10 cm are repeatedly formed. ing. The plate portions are formed at positions where they are parallel to each other and overlap with the same phase. A semi-cylindrical anchor fixture F penetrating vertically in three places in the up-down direction of the plate portion A is attached.

As shown in the figure, the saw-toothed uneven disk Z thus prepared is erected so as to cross the slope. An anchor pin G having a sharpened lower end of the steel bar is driven into the anchor fixing tool F and fixed to the slope, thereby completing "shigara". Generally, "shigara" are generally formed in a plurality of rows at predetermined intervals.

Conventionally, a wooden pile is driven in and "soda" is inserted between the wooden piles.
However, recently it has been using plastic nets instead of "soda" because it takes time and the materials are not available. However, this method also has problems in that the strength is insufficient, so that the interval between the piles must be shortened, and the strength cannot be guaranteed when used for a long term because of poor weather resistance.

Similar to the second and third embodiments, the saw-toothed uneven plate Z having a parallel plate portion shown in the fourth embodiment can set a wide surface of the plate portion in the direction of the force. Therefore, the strength can be effectively utilized. The expanded metal part also has sufficient strength. If the mesh is too large, a fine mesh can be overlaid.

In the case of the present embodiment, it is often installed on a slope having irregularities. In such a case, the plate portion and the bent portions on both edges thereof are very strong, but the expanded metal portion is not provided. It can be slightly bent in the in-plane direction, and it can be adjusted to some extent on site by cutting the strands partially instead of cutting the entire board.

The saw-toothed uneven plate Z of this embodiment can have a large strength while maintaining economic efficiency depending on the design such as using a thick steel plate as a material and increasing the length of the plate portion. it can. By using a strong material, it can be used not only as "shigara" in a narrow sense, but also as a fence for preventing landslides and avalanche.

[0033]

Embodiment 5 In the above embodiment, the saw-toothed unevenness disk Z having the same shape and the same size as the saw-toothed unevenness disk Z is used. As shown in (1), the size of each plate portion A and expanded metal portion B, and the angle of refraction may be changed to meet various demands.

[0034]

Embodiment 6 FIG. 14 shows a saw-toothed uneven plate Z made of a galvanized steel sheet having a thickness of 1.6 mm.
It is a ventilation blind wall 4. Height, ie, saw-toothed uneven plate Z
Is 1 meter, not shown in the drawing. As shown in the figure, a width of 1
The expanded metal portion B having a length of 0 cm is continuously bent at an acute angle, and this is repeated to form an uneven disk shape.

When the ventilation screen 4 faces the wall, the inside of the ventilation screen 4 cannot be seen because the plate portion A blocks the view. However, since the wind passes through the skewed expanded metal portion B, the ventilation is not lost. Plate part A
By combining the ratio of the length of the expanded metal part B with the length of the extruded metal part B, and the angle of refraction at the connection point J, the "thing" that goes straight from a certain direction passes, but the "thing" that goes straight from a certain direction passes. Can create a function of blocking.

The anti-glare plate installed on the separation zone of the road also has such a function, and can prevent the light of the opposing vehicle but allow the wind to pass. In addition, a desire to allow the wind to pass therethrough but to avoid direct sunlight can be realized by using the saw-toothed uneven disk Z of the present invention.

[0037]

[Embodiment 7] In recent years, the river bottom is formed flat with concrete, so that the flow of water is so fast that it is difficult for plants to settle and small animals such as insects cannot be bred. This embodiment proposes one method for solving such a problem. FIG. 15 shows an example of a river sediment holding plate 5 using a robust saw-tooth uneven plate Z made of an extremely thick galvanized steel sheet having a thickness of 4.5 mm.

11 The size of the entire saw-toothed uneven plate used for the sand holding plate 4 is 2 meters in width and 4 meters in length, and a short plate portion A of 20 cm in length standing on the downstream side (left side in the figure). A relatively long expanded metal part B of 50 cm, which is laid on the riverside, is repeatedly formed in an uneven shape.

As shown in FIG. 16, the plate portion A has a saw-toothed shape at intervals of 30 cm in the width direction of the saw-toothed uneven plate Z at a position where the engraved line s of the expanded metal portion B is not cut. A flexible cut K for cutting in the longitudinal direction of the uneven disk is provided. Since the saw-toothed uneven disk is a repeated uneven disk, it is extremely difficult to bend in the width direction because the rib effect of the bent portion is large. By dividing the plate portion in the width direction by the flexible notch K, the saw-toothed uneven plate Z is provided with a certain degree of flexibility also in the width direction so that it can cope with unevenness.

As shown in FIG. 17, such a sediment holding plate 5 is laid on a flat riverbed 50 made of concrete. The board part A is laid on the lower downstream side, and the expanded metal part B is on the upper side. At some places, the anchor pin G is driven into the riverbed 50 and fixed. It is also effective to fix partially using concrete or mortar.

Plate A, Expanded Metal B, and Riverbed 5
0, a substantially triangular retention space 51 is formed.
In the stagnation space 51 and on the sediment retaining plate 5, stones 6 and gravel are filled or placed to fix the riverbed forming plate, at the same time suppress the water speed, and maintain the natural scenery as much as possible. ,
Provide a space for animals and plants to grow.

When formed in this manner, stones and gravel are restrained below and above the riverbed formation plate 5, and the unevenness formed on the bottom reduces the water velocity, so that the sand and gravel run off synergistically. Is reduced. Conversely, fine sediment flowing from the river settles in the space between the stones and gravel, and the sediment sediment is caught in the shade of the plate part, forming a layer of stone, gravel, sand, etc. on the riverbed Is done.

The river bottom forming plate 5 is lighter in weight than a concrete plate or the like, and the effect of the longitudinal flexible cut K provided in the plate portion is quite remarkable. Can be provided, so construction on site is easy.

The problem of rusting is caused by forming a thick zinc-based special plated, extremely thick hot-dip galvanized steel sheet “DAIMAZINK” (registered trademark of Nippon Steel Corporation) made by Nippon Steel Corporation. Has the same or better effect as "dip pickle plating", so it is very effective for large products. The use of extremely thick hot-dip galvanized steel sheet eliminates the problem of rust for many years, so the production process is simple, the cost is low, and the economy is excellent.

In addition, concrete can be exposed because plants can grow and animals can inhabit in the space under the saw-toothed uneven plate or in the sediment retained in the concave portion above the uneven plate. It is possible to maintain a more natural environment than the riverbed.

[0046]

[Embodiment 8] As shown in FIG. 18, after the riverbed forming plate 4 is laid on the ground of the riverbed 50 in which the riverbed forming plate 4 is formed substantially flat, concrete or mortar 7 having a thickness to embed the entire riverbed forming plate 5 is removed. It can also be cast and used to form a reinforced concrete floor. It is also possible to form irregularities on the surface of the cast concrete to form a bottom surface that resists the flow of water.

[0047]

Ninth Embodiment A saw-toothed uneven plate Z provided with a flexible notch K is not only a river, but also a steep slope protected in the past, for example, by mortar spraying, which has deteriorated over the years. It has been considered as a target for renovation because of the social demand for greening. The present embodiment is proposed as one measure to meet such a demand.

The continuous large saw-toothed uneven disk is large and heavy, so it is difficult to transport and install it on the slope. Moreover,
Because of its high rigidity, it is difficult to install it on a slope with many irregularities. In order to solve such a problem, in the present embodiment, an example is shown in which a saw-tooth-shaped uneven disk Z is formed while preparing a saw-tooth forming member and applying the saw-toothed member while on-site.

FIG. 19 shows a saw-tooth forming member N for forming a saw-toothed uneven disk. 2.3mm thick die-maginized steel plate, 180cm wide, N-shaped cross section, 15cm long plate A, 1m long expanded metal part B ・
A plate portion A having a length of 15 cm is formed continuously. Each of the upper and lower plate portions A is divided into three in the width direction by two flexible cuts K parallel to the edge to impart flexibility to the sawtooth forming member N and, at the same time, appropriately provide a connection hole j. Keep it.

As shown in FIG. 20, the plate portions A of the saw-tooth forming member N located on the upper side of the slope and the saw-tooth forming member N of the lower side are engaged with each other, and are sequentially connected by a predetermined method. The concave-convex disk Z is synthesized. In this way, the saw-toothed unevenness plate is completed on the slope, connected to a steel cord S having a large tensile strength fixed to the upper end of the slope, and fixed to the slope, from which vegetation seeds and fertilizer are removed. The vegetated soil M in a slurry state is sprayed to fix the vegetated soil on the slope.

The vegetation soil is stabilized and the vegetation is stabilized by being entangled with the saw-toothed uneven plate laid on the slope. In particular, when the construction is performed as shown in the figure, the soil retaining effect of the plate portion A and the effect of entanglement of the vegetation of the expanded metal portion B are large, and stable slope vegetation can be achieved.

The saw-toothed concavo-convex plate described in this embodiment is provided not only on the slope but also below the base when installing concrete blocks of various shapes for revetment to be installed on the shoreline, for example. It can also be applied to prevent the runoff of sand.

[0053]

Embodiment 10 A rigid surface plate is provided along both the front and back surfaces of the saw-toothed uneven disk, and the periphery is covered with a semi-cylindrical object having a U-shaped cross section to obtain a rigid body such as a honeycomb core. It can also be used to form tall hollow disks.

[0054]

According to the present invention, the expanded metal portion and the flat plate portion are alternately and repeatedly formed, and both portions are alternately bent at a predetermined intersection angle at the boundary between the expanded metal portion and the flat plate portion. It is. Because the thickness of steel used as a raw material for such expanded metal is limited,
When high strength is required, flat expanded metal is used after being formed into a repetitive waveform. If the whole is made of expanded metal, even if it is formed into a repeating waveform, the bent edges are made up of narrow strands with many gaps, so the effect of the ribs is small and the effect of the waveform is small. Not enough.

According to the present invention, instead of refracting the expanded metal formed on the entire mesh portion into a waveform, the expanded metal portion formed into a mesh shape and the plate portion having no cut line are alternately and repeatedly formed. The expanded metal portion and the plate portion are alternately bent to opposite sides at the boundary line to form a saw-toothed uneven disk. Unlike the case where the whole is made of expanded metal, the plate part and expanded metal part are formed in a repeating rib structure without cutting, so the overall strength including refraction strength is dramatically increased it can. In particular, when the plate portions are formed parallel to each other, the effect as a rib is large.

By planning to utilize the functions of the plate portion and the expanded metal portion in addition to having high strength, it contradicts that, as in the case of an anti-glare plate, it allows the wind to pass but does not allow the light to pass. It can also be used for applications that fulfill functions. The strength and function are dramatically improved as compared with general expanded metal, so that it can be used in places where it could not be used conventionally.

In normal production, the expanded metal part is pushed down from the top when expanding while cutting the original plate. When the plate portion is formed, the original plate is fed out flatly, so that the formed expanded metal portion and the plate portion are produced in a state where they are bent at a certain angle. When moving from the original plate to the expanded metal part, the light is refracted at the opposite angle. During production, they are alternately bent at an angle to each other. Producing the original plate of the concave and convex plate by determining the ratio of the expanded metal part and the plate part, and adjusting the refraction angle of each refraction point using a refraction machine to form the desired sawtooth-shaped concave and convex disk Can be.

In the case of use on a civil engineering site, particularly on a slope with a poor scaffolding, the material is heavy and difficult to handle if a single saw-toothed uneven plate is formed. It is also possible to form such a sawtooth forming member and to connect it at the construction stage on site to form a sawtooth-shaped uneven disk.
