Description

anchor {ANCHOR}

It's about anchors.

Pieces such as nails, screws, or pins are typically used to join and fasten two or more objects. However, these pieces may not be stably attached to the object and may be easily shaken or separated depending on the material characteristics of the object to be constructed, so that a firm fastening between the objects may not be achieved. Therefore, an anchor (anchor) is usually additionally used to reinforce the fixing and supporting power of these pieces. For example, concrete, gypsum board, plywood, etc. are damaged during the construction process, and an empty space is easily formed inside the insertion hole of the piece, and this empty space does not provide support to the piece, causing shaking and separation of the piece.

A grating cover refers to a plate made of metal or synthetic resin that is installed across the road or at the edge of a road for water collection or drainage, or used as a scaffolding (top) for walking or moving equipment at a construction site. . The grating cover is formed by orthogonally arranging a plurality of vertical bars generally arranged in a lattice form and creating a through space between the plates. Trench covers are also used for similar purposes. The trench cover forms a plurality of perforations in a plate made of metal or synthetic resin to allow drainage and to allow movement of people or equipment thereon. These grating covers or trench covers are installed long over a considerable distance, but due to manufacturing cost issues, rather than using a small number of very long grating covers or trench covers, they are constructed by combining and connecting multiple grating covers or trench covers. It is common to do On the other hand, in order to prevent the grating cover or the trench cover from being arbitrarily removed from the installation position, it is necessary to fix the grating cover or the trench cover to the side wall of the drainage channel.

However, even when these grating covers or trench covers are connected to each other or fixed to side walls, it is difficult to ensure stable and robust coupling and installation using only screws or nails. So, conventionally, as disclosed in Steel Grating (Registration Publication No. 20-0485651, 2018.02.05 announcement), anchor bolts and the like are additionally used to reinforce their bearing capacity and bonding strength. However, even when they are coupled using an anchor, the stability of coupling or installation is not sufficiently guaranteed, and a portion of the anchor bolt is exposed to the outside, which is dangerous to workers or users and is not aesthetically pleasing.
