Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grating constructed in the form of a lattice or screen, mainly using a metal material such as stainless steel.

Recently, aesthetically pleasing exteriors have been added to automatic doors at building entrances and exits, metal entrance mats used to remove dirt from shoes, and gutter covers used for indoor drains, around buildings, and in gardens. Gratings made of stainless steel have come into use. Generally, this type of grating is made by drilling two or more holes for assembly at the required positions in a narrow strip-shaped vertical strip (also called the main member), and then inserting holes into the horizontal strips ( After inserting the auxiliary members (also called auxiliary members) and assembling them in a lattice shape, side plates are fixed to both ends of the vertical strips by welding, etc., as necessary.
This welding between the side plate and the vertical strip is carried out at the contact points between the top and bottom ends of the vertical strip and the side plate, but this welded area has the disadvantage of discoloration and unevenness, which detracts from the beauty of the stainless steel. Ta. In addition, if each vertical strip is not fixed to the side plate, if an unexpected load is applied to the end of the vertical strip, the unfixed vertical strip may bend or the end may float up. Therefore, it has become desirable to fix the ends of the vertical strips to prevent danger, especially for doormats where the gaps between the vertical strips are narrow in the form of a screen. In some cases, these demands are strong.

The present invention has been devised to solve these drawbacks and meet these demands, and will be described with reference to embodiments shown in the drawings.

Gratings assembled using metal plates such as stainless steel are illustrated in Figure 4 as using vertical strips with a T-shaped cross section as the main member, but in general, this outer cross-sectional shape is of uniform thickness. A rectangular flat bar, an I-shaped eye bar, an L
Angles in a U-shape or U-shape, other square columns, square pipes, etc. are used for this purpose, and the horizontal strips also have grooves that fit and hold vertical strips at predetermined intervals, or round bars or bolts are used. Various conventional methods can be used, such as using spacers, and the method is not limited to the exemplified method.

As shown in FIG. 4, U-shaped locking grooves 6 are carved on both end sides of the vertical strip 1, and as shown in FIG. It has a thickness equal to the depth from the end side of the locking groove 6, and a length approximately equal to the length of the side plate 3, and the vertical strips 1 are arranged in accordance with the spacing between the vertical strips 1. After fitting the locking plate 4 having a locking groove 7 carved therein with a locking groove 7 equal to the width of the vertical portion of the vertical strip 1 into the locking groove 6 on both end sides of the vertical strip 1, on the side surface of the vertical strip 1, etc. The locking plate 4 is fixed to the vertical strip 1 by welding or screws, and then the side plate 3 is fixed to the vertical strip 1.
This is a grating that can be fixed to the locking plate 4 by welding or screws.

Note that the locking groove 7 of the locking plate 4 is shown at the top in FIG.
Although the example is shown in which the grooves are carved on both the lower sides, it is sufficient to carve them only on the upper side or the lower side, and the remaining portion of the carved locking grooves 7 will have the same volume as the locking grooves 6 of the vertical strip 1. do it like this.

After the locking plate 4 is fitted and assembled with the vertical strip 1, it is not necessary to use all of the vertical strips 1 as the locking plate 4, and fixation by welding or the like may be performed at appropriate intervals.

Since the present invention is constructed as described above, the vertical strip 1 and the side plate 4 are fixed to one side of the vertical strip 1 as in the conventional case.
There is no need to fix one book to the side plate by welding, the welded part of the vertical strip 1 and the locking plate 4 is covered by the side plate 3, and the side plate 3 and the locking plate 4 are fixed by welding. Since the welding is done at a location between the vertical strips 1 and lower than the surface, even if the stainless steel becomes discolored due to welding, it will hardly damage the aesthetics because it is internal, and the welding location is also lower than the surface. The more it is, the less noticeable it becomes from the surface.

In addition, since each of the vertical strips 1 is locked on both sides by the locking groove of the locking plate 4 during use, the vertical strips 1 that are not welded will not bend as in the conventional case. , there is no risk of the end floating up or falling, and a safe condition can be maintained.
