Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an expanded metal reinforced in both longitudinal and transverse directions.

[0002]

2. Description of the Related Art Conventionally, when a reinforcing embankment is constructed, as shown in FIG. 1, a flat expanded metal using a thick steel plate having a thickness of 6 mm is replaced with an embankment having an L-shaped cross section. The construction was performed using the surface frame 1. The outline of the construction method is to set the embankment surface frame 1 on the embankment base 20. The embankment surface frame 1 is continuously installed in the lateral direction. The ground plate 11 is connected to the embankment reinforcement 21 laid on the embankment base, and the embankment 2 is placed on the embankment reinforcement 21 behind the embankment surface frame.
do. By repeating such a procedure, the reinforced embankment reinforced in layers is piled up to complete the embankment of a predetermined height.

[0003]

Since the embankment surface frame is made of expanded metal made of a thick steel plate,
The weight is large, and the cost is correspondingly high. In recent years, there has been a strong demand from customers for low-cost, high-performance products with good workability.

[0004]

SUMMARY OF THE INVENTION In order to provide a low-cost, high-strength, and easy-to-install embankment surface frame, according to the present invention, the expanded metal itself is processed to have a bent edge and a corrugated groove. To reinforce the uniaxial direction. The metal reinforced in one axial direction is reinforced by connecting or penetrating a bending edge and / or a corrugated groove to form an expanded metal reinforced in both vertical and horizontal directions.

[0005]

FIG. 2 shows an embankment surface frame 1 used in the present invention. Surface plate 1 made of expanded metal 10
2 is bent twice and 60 degrees in a direction (LW side) perpendicular to the side edge at two places to form two corrugated grooves 31 protruding from the back surface. The width direction (SW side) is reinforced by the rib effect. A long reinforcing plate 3 made of a galvanized steel sheet is provided along the back surface of the surface plate 12. At this time, it penetrates through the openings of the upper and lower two corrugated grooves 31 in the longitudinal direction (L
W side).

[0006]

When formed in this manner, the corrugated groove acts by the rib effect to reinforce the width direction perpendicular to the side edge. The other longitudinal direction is reinforced by a rigid rod penetrating the corrugated groove, so that the bending rigidity increases in both biaxial directions. Accordingly, a perforated plate having high rigidity can be obtained by using inexpensive and widely available expanded metal formed of a thin steel plate.

As shown in FIG. 4, such an expanded metal 10 is bent in the LW direction to form an embankment surface frame 1 having an L-shaped cross section and having a surface plate 12 and a ground plate 11. The angle between the face plate 12 and the ground plate 11 is 60 degrees, the width is 1 meter, the finished length of the surface plate is 1.5 meters, and the length of the ground plate is 50 cm.

The upper end of the face plate 12 refracts one LW of the rhombic opening 13, that is, approximately 50 millimeters, to form a refraction edge 14 parallel to the ground plate. When bending, bend at the intersection of the rhombic openings. The surface plate 12 is pressed at two places of 50 cm and 1 meter from the upper end to form a corrugated groove 31 having a V-shaped cross section.

A long reinforcing plate 3 made of a galvanized steel sheet having a thickness of 3.2 millimeters and having a width of about 4 cm and a length of 2 meters is formed. It is attached to the back of the face plate. At this time, the reinforcing plate 3 is made to penetrate the bending edge 14, the two corrugated grooves 31, and the rhombic opening 13 formed in the ground plate 11. When attaching
The wide width direction of the reinforcing plate is made orthogonal to the surface plate, and the diagonal side of the rhombic opening of the expanded metal in the longitudinal direction LW is penetrated. In some places, the expanded metal and the reinforcing plate are joined to form the embankment surface frame 1.

The reinforcing plate 3 is formed longer than the surface plate, but protrudes above the refraction edge and below the ground plate.
The connection holes 32 are provided at predetermined intervals in the reinforcing plate. When the embankment surface frames 1 are stacked and constructed, the reinforcing plates 3 protruding above and below the surface plate are inserted into and connected to the grounding plate / bending edge. It is convenient in terms of the strength of the embankment surface frame, and is also advantageous in achieving surface flatness.

When the embankment surface frame is formed, as shown in FIG.
A holding plate 33 made of expanded metal having the same mesh as the embankment surface frame formed of a 6 mm steel plate is applied. The holding plate is also provided with a corrugated groove 31 synchronized with the corrugated groove 31 of the surface plate 12. The reinforcing plate 3 can penetrate the surface plate and the holding plate in common.

When the pressing plate 33 is applied, a mat-like material 34 made of a nonwoven fabric or the like, which is so fine as to prevent the earth behind the embankment from leaking, is sandwiched almost entirely between the surface plate 12 and the pressing plate 33. . It is convenient for vegetation if vegetation seeds 35 are attached to the mat-like material. Adjacent embankment surface frames join the reinforcing plates 3 on both edges with long bolts and nuts or the like to maintain the flatness of the surface.

Embodiment 4 FIG. 12 shows an embodiment of an expanded metal 10 called a blind metal. The holes 17 arranged in a zigzag pattern are formed into three-dimensional shielding openings 18 by raising the edges of the holes instead of being expanded as in a general expanded metal.

When processing the expanded metal, including the case of blind processing, a large number of parallel blades, which are perpendicular to the feed direction of the original sheet, are driven into the original sheet so that the holes formed by the driving are expanded. Send out. By feeding the original plate at a desired location without cutting, the flat plate portion 19 having a predetermined length and not subjected to the expanding process can be formed.

As shown in FIG. 13, a shield opening 1 having a predetermined length is provided.

Blind metal has a high strength and a moderate shielding opening. Therefore, when used as a concrete form, it is strong, lightweight, and allows a moderate amount of cement milk to flow. It is also possible to adopt a method such as leveling at a different stage, etc., which is suitable as a concrete formwork. As shown in FIG. 14, a box-shaped container 70 having an open top is attached to the back of the blind metal surface frame 6, and can be used as a disposal mold 7 for forming a concrete wall surface.

As shown in FIG. 15, the cylindrical body 71 using the blind metal surface frame 6 on both sides can insert a reinforcing bar into a space that passes vertically, and can be used instead of a concrete block. As a waste form 7 for forming a wall.

[0028]

Advantages of the Invention Since the expanded metal is bent and reinforced, it is possible to form a plate having high strength in the uniaxial direction. In addition, since the reinforcing member can be reinforced with a reinforcing material penetrating the rhombic hole and the turtle hole, large strength can be obtained in both axial directions. 2. Unlike making a hole by punching an original plate, a cut is made,
Since the cuts are enlarged to form holes, there is no waste of material,
A light, strong, and inexpensive plate can be provided. 3. The use of thin steel plates can reduce the weight, making transportation and construction on the site easier, and the construction cost is lower, making it suitable as a surface plate for reinforced embankment. 4. Since expandable boards can be stacked and a net-like or mat-like material can be sandwiched between them, it can be used for a wide range of applications including light shielding and water permeability. 5. Blind metal with a small aperture ratio is used as a concrete disposal form, but can be formed into a box or a tube and reinforced, and can be used as a disposal form for walls and walls.
