Description

[Detailed Description of the Invention] The present invention relates to a grid-like grating used for entrance mats and the like, which are assembled in a grid-like manner mainly using a metal material such as stainless steel.

Recently, stainless steel with a beautiful appearance has been used for automatic doors at building entrances and exits, entrance mats used to prevent dirt, gutter covers attached to gutter attached to buildings, pool grooves and washing areas. The grating that was used is now being used. Generally, this type of grating uses a vertical piece with a narrow strip-like appearance as the main member, and has two or more locking holes drilled for assembly, and bolts, nuts, etc. It is common to use spacers to maintain predetermined intervals, or to assemble them in a lattice pattern using horizontal strips with locking grooves, such as the bars of a shoji screen. In addition, gratings used in places where people walk on, such as entrance mats, are vertical strips that narrow the gap between the main vertical strips and have a horizontal strip-shaped top plate at the top. is used. That is, the cross-sectional shape is T-shaped, I-shaped, H-shaped, and inverted L.
Vertical strips in a U-shape, U-shape, or Z-shape, square pipes, etc. are used alone or in combination as the main components, but due to the gap between the main components, The bottom of the trench and the floor surface of the place where it is installed can be seen through, and dirt such as dirt that falls inside spoils the beautiful appearance, and pebbles and fallen leaves fall into the gaps, making it difficult to clean. There is a desire to improve this.

The present invention was made in response to such a demand, and includes a shielding material having a width and length that is approximately equal to the gap between the vertical strips of the main members and the top plate between the main members. This problem can be solved by installing the vertical strip of the main member so that the upper surface thereof is lower than the lower surface of the top plate and positioned below the gap so as to cover the gap when viewed from above.

That is, in the embodiment shown in FIGS. 1 and 2, the vertical strip 1 constituting the main member has a T-shaped cross section, and the vertical strip 1 is connected to bolts 4, nuts 5, and spacers 6 for maintaining constant spacing. In the grating assembled in the form of a screen using
As a shielding material 2 for shielding a gap formed between a top plate 3 formed horizontally on the top of the top plate 3 and a top plate 3 of an adjacent vertical strip 1, a top plate having a width and length approximately equal to the width and length of the gap is provided. ,
The shielding material 2 has a T-shaped cross section and is lower in height than the vertical strip 1 of the main member, and the upper surface of the top plate is lower than the bottom surface of the top plate of the vertical strip 1 of the main member, and is assembled into a screen shape. It is. That is, in this embodiment, vertical strips having T-shaped cross sections of the main member having different heights are used and assembled alternately, and the top plate of the vertical strip 1 of the main member and the top plate of the shielding material 2 are assembled alternately. The plates are assembled so that they are flat with no gaps when viewed from above. In addition, as in the embodiment shown in FIG.
The shielding material 2 in the form of a rectangular planar plate may be fixed to the spacer 6 by welding or the like so as to be placed in the center.

As shown in Fig. 5, some of the main vertical strips 1 have various cross-sectional shapes such as I-shapes, H-shapes, T-shapes, and inverted L-shapes, which are also used for general gutter covers. The shielding material 2 may be made of shaped steel, or made by bending or pressing a thin plate or pipe, and the shielding material 2 is a flat plate 7 having approximately the same length as the main strip-shaped member, and has locking legs as shown in FIG. 4. The pieces 8 may be vertically installed by welding or the like, and the shielding material 2 is simply not visible from the surface, prevents fallen leaves, pebbles, etc. from falling between the vertical strips of the main member, and is designed to be similar to the main member. Since load-bearing capacity is not required, there is no problem in manufacturing it from a thin plate.

Since the present invention is constructed as described above, even if pebbles or fallen leaves enter the gaps between the vertical strips of the main member, they will be supported by the shielding plate and can be easily removed with a broom, etc., without falling into the groove or installation surface. can be cleaned,
It is suitable for entrance mats, automatic door mats, etc. because the inside of the groove or the installation surface that is dirty with fine mud or dust cannot be seen through, and the aesthetic appearance is not spoiled.

In addition, in this embodiment, a grid-like grating with no side plates attached is shown, but the side plates may be provided by welding or screws, and in addition to using bolts, nuts, and spacers as auxiliary members, As shown in FIG. 5C, a horizontal strip 2 may be used in which locking grooves having the thickness of the vertical portion of the vertical strip 1 are equally spaced between the vertical strips 1. In this case, the shielding material 2 It may be fixed by assembling and welding so that it is placed on the horizontal strip 2 directly or by providing leg pieces.
