Description

{SAFETY SCAFFOLDING FOR WORK}

The present invention relates to a safety footrest for a work, and is installed on a temporary scaffold such as a scaffold installed for working in a high place when various buildings and ships are manufactured and repaired. The safety footrest for a work serves as a passageway and a workbench of an operator and generally has a through hole formed at an upper surface of a flat plate portion having a predetermined length and width at regular intervals, So that the worker can work on the safety footstroke stably without slipping by the burr.

However, since the burr has a smooth upper surface, the burr is easily worn during a long period of use, and the original slip prevention function can not be properly performed. In the case where the burr is wet due to rain or other factors The worker slipped easily.

As described above, when the worker slips in the safety footrest for work, it is very important to increase the slip prevention function of the safety footrest because the safety footrest installed on a high place mainly causes lifting accidents such as a fall accident of an operator. As described above, there is a limit to the slip prevention function by the burr of the through hole of the conventional safety footrest for work.

Accordingly, FIG. 1 shows a Korean Utility Model Patent No. 20-2005-0032000 (design name: safe safety footrest with improved anti-slip function) presented to solve such a problem.

Referring to FIG. 1, the present invention is characterized in that a burr 5 is projected upward along an edge of a through hole 4 formed at a predetermined interval in a flat plate portion 2, Thereby forming a portion 6. This is because the worker's footsteps on the flat plate portion 2 of the safety footrest 1 are brought into contact with the projections and depressions 6 formed on the burrs 5 so that the load of the worker is concentrated on the sharp blade of the projections and depressions 6, The shoe portion of the shoe portion 6 is pressed relatively deeply and the shoe portion of the concave and convex portion 6 is pressed relatively thinly so as to form a sharp inclination angle with the shoe surface of the shoe surface, So that slippage can be prevented even when the flat plate portion 2 is holding water or material.

However, the sharp blade of the concave-convex part 6 has a larger number of contact with the shoe surface than the blade-free part in the concave-convex part 6, and the contact strength is stronger, Abraded, and the function is lost because the protrusion can be easily bent by the strong pressure.

The object of the present invention is to provide a safety footrest having a function of preventing slippage so that an operator can not easily fall over. The object of the present invention is to provide a safety footrest having a slip- The present invention relates to a safety footrest for work which is not easily bent.

In order to achieve the above object, the present invention provides a frame having bending portions on both sides thereof; A plurality of protrusions formed on the frame and protruding upward, the protrusions having the longest protrusions and the protrusions protruding from both ends; And a plurality of protrusions formed on the protrusions, wherein protrusions bent inward are formed in the protrusions.

In addition, the apparatus may further include a connecting portion formed between the plurality of projecting portions and projecting upwardly of the frame, wherein a height at which the connecting portion is projected is lower than a height of the projecting portion.

The protruding portion of the protruding portion protrudes in a semicircular elliptical shape and further includes a plurality of through holes formed in the frame.

The present invention relates to a safety footrest for work, more specifically, a plurality of protrusions formed at various angles, and a plurality of protrusions are formed on the protrusions, so that a contact area between the protrusions and the operator is widened, Thereby preventing the operator from slipping on the safety foot plate and forming a plurality of inwardly bent portions in the concavo-convex portion, so that it is easily worn and not bent.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 2, the present invention includes a plurality of protrusions 20 protruding upward from the upper surface of the frame 10, and a through-hole 21 is formed between the protrusions 20. The through-hole 21 serves not only to reduce the weight of the safety footrest but also to remove the rain or various liquids or various foreign substances from the footrest. Therefore, it is preferable that the through-hole 21 is formed on a surface projecting downwardly. The formation of the through-hole 21 is required to increase the force necessary for advancing the forming operation for forming the projecting portion 20 There is also a saving effect.

3, a plurality of protrusions 24 are formed on each of the protrusions 20, a frame bend 23 is formed on both sides of the frame 10, 23) is folded once into the lower side and then once inside the safety footrest. A plurality of fasteners 22 for fastening the safety footrest to the installation frame are formed in the frame bend section 23. [

Each of the protrusions 20 has a shape of a long oval in one direction (major axis) and a shape in which the inside of an oval shape is penetrated. Also, the protruding portion 20 has a shape in which the inner space gradually becomes narrower toward the upper side, and the projecting shape of the protruding portion 20 has a semi-circular elliptical shape. That is, the distance between the middle portion of the projecting portion 20 and the upper surface of the frame 10 is the longest, and the distance from the middle portion of the projecting portion 20 to both ends decreases. Because of the shape of the protruding portion 20, the area of contact between the protruding portion 24 formed on the protruding portion 20 and the shoe of the operator is widened and the angle of the protruding portion 24 is increased. It has an effect of maximizing the function of the slip prevention.

4A, a downwardly bent protruded bent portion 26 is formed inside each of the protruded portions 20 for reinforcing the strength of the protruded portion 20, and the protruded bent portion 26 Therefore, it is possible to prevent the protruding portion 20 from being worn or bent even if the safety footrest is used for a long period of time by the formation of the protruding bent portion 26. In addition, can do.

4B and 5, a connecting portion 25 protruding upward as in the case of the protrusion 20 is formed between the respective protrusions 20 arranged along the major axis direction of the protrusion 20, Thereby filling the empty space formed between the respective projections 20, thereby preventing a space between the footwear of the operator and the safety footplate, and thus a more stable movement effect can be obtained. In the embodiment of the present invention, the connecting portion 25 protrudes in a curved shape having a wave shape when viewed from a cross section cut along the minor axis direction of the protruding portion 20, and the protruding portion 25, And the height of the center portion, which is a portion, is lower than the height of the projection.

6A and 6B, in the case of the safety footrest according to the present invention, the irregularities 24 of the protruding portion 20 protruding in a semicircular elliptic shape are entirely brought into close contact with the bottom surface of the shoe of the operator as a whole, The force applied to the shoe of the worker is evenly distributed through the concave and convex portions 24 and the connecting portions 25 at different angles because the connecting portion 25 formed between the shoes 20 supports the bottom surface of the shoe of the worker When the surface on which the protrusions 6 of the protrusions 5 are formed is parallel to the upper surface of the frame 2 as in the prior art, Since the abutting portion 6 abuts only the portion where the concave and convex portions 6 are formed, the force is concentrated and stably stands or is difficult to move. In addition, the worker's foot is inclined at an angle to form a space between the plurality of projecting portions 5,When the foot side will enter the center of gravity of the moment, so the worker can move to lead a large company logo.

The safety footrest for use in the present invention is not limited to the above-described embodiments, but may be modified in various ways within the scope of the technical idea described in the claims of the present invention.
