Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to an expanded metal in which a flat plate portion having a predetermined length and continuous in a width direction is formed on the expanded metal, and a connecting mechanism is attached to the flat plate portion.

[0002]

[Prior art]

 Conventionally, apart from a thin lath net having a thickness of 0.5 mm or less, a nominal thickness of 1. Since it is difficult to form a flat plate portion for expanded metal made of a steel plate of 2 mm or more, the entire surface is expanded, and the one with the flat plate portion is not supplied industrially.

[0003] In the case of JIS-standard expanded metal, the size of the opening is at least 12 x 30.5 mm. Therefore, if a flat plate portion is not provided, the expanded metal can be attached to another object or expanded. When connecting metals, it was difficult to use screws or bolts and nuts, so it was necessary to apply a large washer and then bolt or weld. Even if a flat plate is provided, the thickness of the plate is at least 1.2 mm, so it is difficult to drill bolt holes easily on site, and it is difficult to use bolts and nuts.

[0004] Even if welding is to be performed, since the expanded metal has many openings, it is difficult to find a suitable welding point, which requires time and effort and increases the cost. In the case of expanded metal made of galvanized steel sheet, smoke or foul odor is generated at the time of welding, so that workability is poor and there is a problem in the reliability of adhesion.

[0005]

[Problems to be solved by the invention]

 The purpose of this invention is to make it possible to easily, safely and economically connect expanded metal made of galvanized steel sheet having a thickness of 1.2 mm or more.

[0006]

[Means for Solving the Problems]

 In this invention, when producing expanded metal using a steel sheet with a nominal thickness of 1.2 mm to 6 mm, which is generally called a hot-rolled steel sheet, a full width sheet is sent out while feeding a fixed width original sheet in the longitudinal direction. Using a large number of blades arranged side by side, a staggered cut is made in the steel plate, and the original plate is pulled in the longitudinal direction to provide a diamond-shaped opening on the entire surface.

According to the present invention, in such a production process, a cut is stopped at a start position, an end position, and a predetermined intermediate position, and only a feed is performed, so that a flat plate portion continuous in the LW direction is provided. Is provided. Secondary processing is performed on the attached flat plate portion to form a connection mechanism such as a connection hole, or the flat plate portion is bent or bent to form a reinforcing mechanism.

[0008]

[Action]

 By providing a flat plate portion and a connecting mechanism such as a bolt hole in the flat plate portion, the connection can be easily performed. Also, by bending at the flat plate portion or cutting at the flat plate portion, burrs generated by cutting the expand are avoided. In addition, secondary processing such as bending and joining is performed on the flat plate. Further, a reinforcing mechanism can be provided by bending and bending the flat plate portion. It is also possible to juxtapose and form a semi-cylindrical shape by bending and use a long link to form a composite.

[0009]

Example 1 FIG. 1 shows an expanded metal 1 using a galvanized steel sheet and specified in JIS standard XS-42, having a plate thickness of 2.3 mm, a strand of 2.5 mm, and a SW22. It has a rhombic opening 11 in millimeters, LW about 51 millimeters. The expanded metal part 10 has a width of about 1 meter and a length of about 1 meter. At the upper and lower end portions in the feed direction, flat plate portions 12 with no cuts connected to the entire width are provided. The length of the flat portions is 10 cm each. The flat plate portion 12 is provided with six connection holes 13 each having a diameter of about 1 cm, each having a diameter of about 15 cm.

As shown in FIG. 2, the flat plate portions 12 at both ends of the expanded metal 1 are bent at a right angle in the same direction to form angle-shaped reinforcing edges 21 having a width of 5 cm on upper and lower edges. I do. The panel 2 has a U-shaped edge with a cross-sectional shape.

As shown in FIG. 3, such a panel 2 can be extremely easily connected by a method in which the reinforcing edges 21 are pressed against each other and bolts 31 and nuts 32 are used. Further, a connecting hole 13 can be additionally provided to enable easy connection.

[0012]

Embodiment 2 An example in which an embankment surface plate is formed using an expanded metal having the same standard as the previous example will be described. As shown in FIG. 4, a flat plate portion 12 having a width of 20 cm is attached to both side edges of a band-shaped expanded metal portion 10 of an expanded metal 1 having a width of approximately 150 cm and a length of approximately 25 cm. An elongated connection hole 13 is provided in the center of the flat plate portion at a predetermined interval.

The upper and lower flat plate portions are bent at a position near the expanded metal portion to form a strip member 41 having a height of 25 cm and a substantially Z-shaped cross section, as shown in FIG. The slope portion 42 of the belt-shaped member 41 is constituted by an expanded metal portion 10 provided with a large number of rhombic openings 10. Behind the expanded metal part, a vegetation sheet 43 made of a synthetic resin woven cloth is attached. If vegetation seeds are attached to the vegetation sheet, greening will be easier.

As shown in FIG. 6, four such band-shaped members 41 are stacked in a horizontal state, and in some places, a connecting rod 44 penetrating the connecting hole 13 in a vertical direction or a bolt nut is used. Then, the surface plate 40 is formed by being securely connected. The connecting rod 44 is formed so as to protrude downward so that it can be inserted into the ground when the surface plate is installed.

[0015] A reinforcing sheet 46 made of a fiber net or the like having a high tensile strength, which is generally called a geogrid, is spread over the embankment base 45 with its tips aligned along the reference line. On the front end of the reinforcing sheet 46, the surface plates 40 are arranged in parallel. The tip of the reinforcing sheet 46 and the bottom surface of the surface plate 40 are securely connected.

After preparing in this manner, embankment 4 is performed behind the surface plate 40 and on the reinforcing sheet 46. Fill the embankment firmly. On the first-stage embankment, a reinforcing sheet 46 is laid, a surface plate is installed, and the embankment is laid behind the same, thereby completing the embankment 4 having a predetermined height.

Although the earth pressure of the embankment is received from behind, the belt-shaped member 41 is a semi-cylindrical material having a relatively low height, and it is securely connected vertically by a connecting rod or a bolt nut. It has high rigidity and is supported by a reinforcing sheet, so it can sufficiently receive earth pressure.

Using the first layer embankment 4 as an embankment base, the same operation as described above is repeated, and a step-type reinforcing embankment reinforced with a plurality of reinforcing sheets 46 is completed. A vegetation sheet with vegetation seeds is attached to the back of the expanded metal of the band-shaped member, so that the surface is greened over time. The belt-shaped member has a Z-shaped surface and is formed on a slope, so it is suitable for vegetation. Since the small steps 47 formed on the front of the embankment are flat, they are suitable for planting small trees 5 and the like.

In this embodiment, a belt-like member having a substantially Z-shaped cross section was used to construct the surface plate. However, as shown in FIG. It is also possible to form the surface plate 40 using a band-shaped member 41 formed of a band-shaped expanded metal having a flat plate portion and having a substantially U-shaped cross section. As in the case of the Z-shape, a plurality of members are stacked, and a connecting plate 48 in a crossing direction is attached to the back surface of the expanded metal part 10 on the surface so as to be in close contact with the surface plate. Since it is reinforced, bending can be reduced.

[0020]

Embodiment 3 This is another example of the embankment surface plate. FIG. 8 shows a special expanded metal 1 made of a 3.2 mm thick zinc-plated steel sheet. The band-shaped flat plate portions 12 and the band-shaped expanded metal portions 10 are alternately arranged in parallel. The expanded metal part has a rhombic opening 11 having a mesh size of about 22 SW and a LW of about 50 mm. The flat plate portion 12 is provided with an elongated through-hole 13 having a width of 3 cm and a length of 10 cm in a direction intersecting with the band direction at three places at both ends and a center.

The expanded metal 1 is refracted in the LW direction to form a substantially L-shaped embankment surface base 6 having an overall cross section having an inclination of about 60 degrees as shown in FIG. The upper end bends the flat plate portion 12 at a position near the end to form a reinforcing edge 21. Subsequent to the band-shaped flat expanded metal portion 10, a V-groove portion 62 formed by bending a flat plate portion twice and the expanded metal portion 10 forming a slope are alternately formed. At the lower end of the surface plate, a horizontal ground plate 61 formed by bending a flat plate portion is formed.

A reinforcing plate at the upper end, a V-shaped groove, and a vertical connecting plate 48 penetrating the ground plate are attached to the back surface of the expanded metal portion 10 so as to be in close contact with the expanded metal. 6 is reinforced.

[0023]

[Embodiment 4] An example of forming a large container that can be used in civil engineering work as an alternative to a wire mesh gabion will be described. FIG. 10 shows a long expanded metal 1. Flat plate portions 12 are formed at both ends and at two places at intervals of 50 cm in the middle. Connecting holes 13 are provided in the flat portions on both edges at places near the edges. Such expanded metal 1 is refracted at the center of the middle flat plate portion 12 at the right angle to the same side to form a large semi-cylindrical body 7 shown in FIG.

As shown in the figure, a flat portion at the upper end of both sides of the semi-cylindrical body is folded outward to provide a semi-cylindrical edge 71. On its back side, a narrow insertion groove 72 is formed. Through holes 13 are provided in some places on the semi-cylindrical edge.

Such a large semi-cylindrical body 7 can be used, for example, as a substitute for a gabion. As shown in FIG. 12, the semi-cylindrical bodies 7 are continuously installed along the foundation of the embankment so as to abut in the longitudinal direction. Gravel 8 is packed into the connected semi-cylindrical body 7 to solidify it. On the embankment side, a finely permeable sheet 73 is stretched behind the semi-cylindrical body, and the embankment 4 is placed behind it.

When the semi-cylindrical body 7 is formed, as shown in FIG. 13, the cross-section of one end of the main body of the semi-cylindrical body is slightly smaller than the cross-section of the other end. Keep it small. Conversely, at the end of the small cross section, the semi-cylindrical edge 71 (insertion groove 72) to be formed is formed slightly wider than the cross section of the other end.

When formed in this manner, a narrow end can be fitted inside the wide end of the semi-cylindrical body 7. The insertion groove is reversed, and the connection is extremely simple because the wide insertion groove at the narrow end is overlapped over the narrow insertion groove at the wide end.

In the case of performing such fine processing, it is very difficult with expanded metal. However, in the case of the present invention, since the portion to be bent is constituted by a flat plate portion, the processing becomes easy, and it is feasible. Become.

[0029]

[Effect of the invention]

 1. At the time of production of expanded metal, a flat portion having no cut of a predetermined length is formed at a predetermined position in the feed direction. By providing a connection mechanism such as a bolt hole in the flat plate, connection can be made without welding. Work environment can be improved. 2. Cutting the expanded metal was dangerous because sharp cuts formed on the cut surface. The burr problem can be solved by providing a wide flat plate and designing the material to cut inside the flat plate. 3. Expanded parts are not uniform in thickness, strength, elongation, etc., as in the case of flat parts, and are cut off, making it difficult to bend. In the present invention, a flat plate is provided at a place where bending is required, and the flat metal is bent to form a rib, thereby facilitating the processing of the expanded metal.
