Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement of a metal grating receiving frame such as a groove cover or a square cover.

(Conventional technology) Openings such as side gutters and sewage basins are embedded with metal grating support frames called gratings, into which metal gutter covers and basin covers can be opened and closed. This type of grating receiving frame is bulky because it usually has a frame main body made of cast iron, etc., and a plurality of anchor fittings for fixing the receiving frame are welded together with their upper ends on the opposing outer surfaces.
This was not only inconvenient in terms of storage and transportation, but also resulted in high costs.

(Problem to be solved by the invention) The problem to be solved by the invention is to provide a metal grating receiving frame that eliminates the above-mentioned drawbacks, can be stored and transported without being bulky, and can be provided at low cost. It is in.

(Means for Solving the Problems) The grating support frame of the present invention, which attempts to solve the above-mentioned problems, comprises a plurality of anchor supports provided with vertical engagement holes on opposing outer surfaces at required intervals. The present invention is characterized in that it consists of a frame main body welded at the same time, and a plurality of anchor metal fittings for fixing the receiving frame, each having a downward hook portion at the upper end that can be forcibly fitted into the engagement hole of the anchor receiving frame.

(Function) Such a grating receiving frame is stored and transported with the frame main body and the anchor fittings for fixing the receiving frame separated, and after arriving at the installation site, the receiving frame is inserted into the engagement hole of each anchor holder of the frame main body. The fixing anchor metal fitting is driven in with the downward hook part of the upper end to forcibly fit it, and then it is embedded and integrated into the opening of a concrete groove such as a side gutter or a sewage basin, just like the conventional receiving frame for this type of grating. Bye.

(Embodiments) Next, the present invention will be described in detail with reference to illustrated embodiments.

1 has a rectangular cast iron frame main body,
A plurality of anchor holders 2 having vertical engagement holes 3 formed from strips made of general structural rolled steel plates are arranged at required intervals on the opposing longitudinal outer surfaces of the frame main body 1. It is welded into one piece. Reference numeral 4 denotes an anchor fitting for fixing a receiving frame formed from a strip made of a general structural rolled steel plate. A downward hook part 5 that can be fitted is integrally molded on the upper end of the anchor main body 6. Note that 7 in the figure is a bent leg portion at the lower end of the anchor main body 6.

In a case configured in this way, the frame main body 1 is always
Since the frame main body 1 and the anchor fittings 4 for fixing the receiving frame are separated, it is possible to stack the frame main body 1 and to package a large number of anchor fittings for fixing the receiving frame at once, and both can be stored and transported without being bulky, thus reducing logistics costs. This means that it is possible to reduce the However, when using
At the installation site, the anchor fittings 4 for fixing the receiving frame are inserted into the upper end openings of the engagement holes 3 of each anchor receiving plate 2 of the frame main body 1.
If you apply the lower end of the downward hook part 5 at the upper end and drive it with a hammer etc., the downward hook part 5
is forcibly fitted into the engagement hole 3, and the anchor fitting 4 for fixing the receiving frame is connected and integrated with the anchor receiving frame 2 without any wobbling.Then, as with the conventional receiving frame for this kind of grating, the rest is made of concrete such as a side gutter. If it is embedded and integrated into the opening of a groove or sewage basin, the metal groove cover or sewage basin cover can be inserted into the opening of the concrete groove or sewage basin so that it can be opened and closed while being reinforced by the anchor fitting 4 for fixing the receiving frame. A metal grating support frame will be embedded and integrated.

(Effects of the invention) As is clear from the above description, in the present invention, the main body of the frame and the anchor fittings for fixing the receiving frame are normally separated, making it possible to store and transport without adding bulk, reducing logistics costs, etc. It has the advantage of being able to be provided at low cost since it can be significantly reduced.

Therefore, the present invention has extremely great practical value as it solves the problems of the conventional metal grating frames of this type.
