On the other hand, the conventional opening cover is often used for the wood plate, but in the case of the wood plate is not enough to cope with the weight of the construction tools and the worker, there was a problem that the worker can not completely prevent the accident falling into the opening. .

In addition, even when the opening cover is made of steel, openings such as pits and holes installed in the construction site are very diverse in size and shape, and thus, once used, the opening cover structure is difficult to use in other workshops, and thus has poor recyclability. .

In order to solve this problem, Korean Utility Model Registration No. 398872 is made of a metal material, and at least one row of fitting holes are formed along a circumference at regular intervals at regular intervals from the outer edge to the inner side and have a constant thickness. A fixing base composed of a rectangular base plate, a pillar having a length protruding outward through a plurality of fitting holes, and a head formed on an upper surface of the pillar and having a diameter larger than the diameter of the fitting hole. Architectural opening covering structures are disclosed.

In the case of the cover structure, it is possible to correspond to the openings of various sizes and shapes, there is an advantage that the recyclability is improved. The cover structure covers the base plate in the opening and fixes the cover structure by moving a fixing piece such as a bolt into the base plate fitting hole near the edge of the opening. However, when the fixing piece such as a bolt is inserted, when the worker touches the base plate, it may rotate around the fixing piece to expose a part of the opening, and the worker or the tool may fall to the exposed part to lead to a safety accident. There is concern.

In addition, since the base plate should be manufactured to a considerable thickness in consideration of the weight of the worker and the work tool, a step is generated in the workplace by the edge of the base plate and acts as a kind of obstacle, so that a safety accident occurs when the worker falls down. Or moving the tool.

In addition, when the fixing piece is fixed to the base plate, due to the head having a diameter larger than the diameter of the fitting hole, the head protrudes on the upper surface of the base plate. Accordingly, the protruding head may also cause an accident to fall when the worker moves or make it difficult to move the work tool.

In order to achieve the object of the present invention, the present invention is a cover structure for covering an opening, such as a cavity or a hole in a building site, the cover structure is a base plate having a plurality of fitting holes formed inward from the outer edge, and It is provided with an opening cover structure comprising a fixing piece which is inserted into the fitting hole to fix the base plate and the joints connecting the ends of the two or more leg portions with each other.

As described above, the cover structure of the present invention uses a fixing piece consisting of a joint portion interconnecting two or more legs and end portions of the two or more legs, so that the two legs are fixed when the opening edge is fixed, so that the operator If you touch the plate, the base plate does not rotate.

In addition, although the leg portion of the fixing piece of the present invention may be three or more, preferably from the viewpoint of cost, etc., it consists of two leg portions, characterized in that forming a substantially "C" shape.

In addition, in order to achieve another object of the present invention, the present invention provides an opening cover structure in which at least one edge of the base plate is tapered so that the worker is not caught by the end of the base plate when the worker moves.

When the tapering process is performed on the edge of the base plate in this way, the operator does not trip over the edge of the base plate, and the movement of the work tool is facilitated.

Further, in the base plate of the present invention, a groove is formed between the fitting hole and the fitting hole of the base plate, so that the joint does not protrude on the base plate even when the fixing piece is inserted into the fitting hole. An opening cover structure is provided.

Thus, the groove is formed between the fitting hole and the fitting hole of the base plate, and the joint part of the fixing piece inserted into the two fitting holes to fix the base plate does not protrude to the upper surface of the base plate, The fixing piece does not trip the worker or hinder the movement of the work tool.
