Description

Technology Field

[0001] The present invention relates to a spacing and width-adjustable grating for non-slip prevention, and more specifically, to a spacing and width-adjustable grating for non-slip prevention that allows non-slip members installed at regular intervals so as to be exposed upwards to be combined with various installation numbers by inserting diamond-shaped connecting bars, and enables the width of the connecting bars to be adjusted through spacing adjustment members inserted into the connecting bars between the non-slip members, thereby improving non-slip and rigidity without welding. Background Technology

[0003] Generally, the grating is installed by forming I-bar shaped bearing bars and screw-shaped crossbars at regular intervals between side frames on a frame embedded in the upper side of the drainage channel through welding or the like, thereby serving to filter out relatively large foreign substances so that they do not enter the drainage channel.

[0004] In addition, the frame and the edge of the grating are installed with a certain gap between them so that the grating can be easily attached and detached, thereby serving the role of filtering foreign substances as described above and simultaneously allowing foreign substances that have entered the drainage channel to be easily cleaned.

[0005] However, as described above, due to the gap formed between the frame and the edge of the grating to facilitate easy detachment of the grating, the grating moves during vehicle passage or pedestrian walking, resulting in a problem where significant friction noise occurs between the grating and the frame.

[0006] Accordingly, in the past, a method was used to fix the grating by fastening it to the edges or frame using separate fastening means such as bolts in order to eliminate the aforementioned friction noise; however, this method had the problem of being unsuitable for practical use because it reduced work efficiency due to additional work and incurred high costs.

[0007] In addition, rubber or the like has been installed between the grating and the frame, but even with this method, as time passes, the rubber deteriorates or wears down, so it is not very effective in preventing noise.

[0008] Meanwhile, since the grating is made of metal, a section where bearing bars and screw bars are installed alternately on the upper side and a space using straight support members are installed in sequence, and irregularities are provided on the upper side of the support members to prevent slipping.

[0009] However, when slip prevention is achieved by creating irregularities on the upper side of the support member, it is more effective in preventing slip compared to the case where there is no shape. However, there is a drawback in that it is difficult to fundamentally prevent slip caused by the irregularities, and it is necessary to adjust various widths depending on the installation location of drainage channels, etc. Since the bearing bar and screw bar are fixed by welding at regular intervals, a significant amount of time and labor costs are consumed for welding, and there is a practical drawback in that it is very difficult to form them to have various widths.
