JPS58101931A - Flat steel with projection - Google Patents

Abstract

PURPOSE:To permit the application of a flat steel with projections especially in the fields of ornaments and civil work by using a material formed by providing projections distributionally on both sides in the widthwise direction of a steel body having specific thickness, width, and length. CONSTITUTION:Projections 11 are distributionally formed over the whole surfaces on both sides in the widthwise direction of a steel body 10 with 2-5mm. in thickness, 20-250mm. in width, and 2,000mm. or more in length. Since such a flat steel material is thin, it is particularly suitable for various use in addition to ornaments, reinforced concreting for civil work, etc. Moreover, it is easily bent and handled, further can be produced inexpensively. For example, one end of the flat steel material is connected to a sheet pile and buried in soil in such a way as to extend it at a right angle to the sheet pile, whereby permitting the sheet pile to be strongly anchored.

Description

[Detailed description of the invention] This invention relates to a flat bar with projections.

Conventionally, there has been a proposal as shown in Japanese Patent Publication No. 52-6011 as a flat bar with protrusions suitable for use as reinforcing bars in reinforced concrete, but in civil engineering work, the frictional force with the soil is used to fix sheet piles, etc. They may be used for occasions or for decorative purposes, and in such cases, they may be expensive due to their thickness, cannot be easily bent, or are heavy and inconvenient to handle. be.

The present invention provides a flat bar with projections that is suitable for use in such cases and can also be used as reinforcing bars for reinforced concrete.

The flat bar with projections according to the present invention has a thickness of 3 mm or more and less than 5 mm, a width of 20 to 250 mm, and a length of 2000 mm.
Both sides of the main body section in the width direction are covered.

In one embodiment of the invention shown in FIGS. 1 and 2, 1
0 is long and continuous in the left and right directions in the main body, and a large number of protrusions 11 are formed on both sides of the main body, which are wide in the width direction, and arranged at approximately equal intervals in the direction perpendicular to the longitudinal direction. These protrusions may not be arranged at equal intervals but may be arranged at different intervals.

The protrusion 11 may be inclined as shown in FIG. 3, or may be circular as shown in FIG. 4, or may have a fifth shape.

The flat steel with protrusions according to the present invention is suitable for use as a decoration by bending, for example, and can be buried at one end by joining it to a sheet pile used in civil engineering work and extending in the soil in a direction perpendicular to the sheet pile. It is suitable for engaging the soil, such as for use in firmly fixing sheet piles, and can also be used as reinforcing bars for reinforced concrete.

As mentioned above, the flat bar with projections according to the present invention has a thickness of 3
Since it is more than 5 mm in diameter and less than 5 mm in thickness, it is thin and particularly suitable for use in various applications other than reinforced concrete, such as decoration and civil engineering, and is easy to bend, lightweight, easy to handle, and can be manufactured at low cost. This has the effect of

Claims (1)

[Claims] A flat bar with protrusions having a width of 20 to 250 mm and a length of 2000 mm or more and having a thickness sufficiently thinner than the width and having protrusions distributed over the entire surface of both sides in the width direction of the main body,
A flat bar with projections, wherein the thickness of the main body portion is 3 mm or more and less than 5 mm.
