Description

[Detailed description of the invention] (Industrial application field) This invention is a screen-like structure that is assembled into a screen-like structure using metal materials such as stainless steel, and is used for gutter covers attached to buildings, entrance mats, etc. This relates to gratings.

(Prior technology) Recently, automatic doors at building entrances and exits, entrance mats used to prevent indoor dirt, gutter covers attached to gutter attached to buildings, pool gutter and washing area, etc. Gratings made of stainless steel have come to be used because of their attractive appearance. Generally, this type of grating uses a vertical strip with a narrow strip-like appearance as the main member, and has two or more locking holes drilled for assembly.
It is common to use bolts, nuts, and spacers to maintain predetermined spacing in the locking holes, or to assemble them in a lattice shape 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 made by narrowing the distance between the vertical strips, which are the main members, and having a horizontal strip-shaped top plate at the top. pieces are used. That is, vertical strips, square pipes, etc. having a T-shape, I-shape, inverted L-shape, U-shape, Z-shape, etc. in cross-section are used singly or in combination as the main member.

(Problems to be solved by the invention) As stated above, the constructed grating is
The bottom of the trench and the floor surface of the place where it is installed can be seen through the gaps between the vertical strips, which are the main components, and dirt such as mud that falls inside spoils the aesthetic appearance.
There are drawbacks such as pebbles and fallen leaves falling into the gaps and cleaning is not easy, and it is desired to improve this, so the applicant of the present application proposed a shielding plate below the top plate of the main member as Utility Application No. 58-25005. We have been proposing and manufacturing and selling grid-like gratings with attached gratings, but since beautiful stainless steel is expensive, the main component is 1 to 2 mm thick, so it is used as a gutter cover for vehicles, etc. to pass through. In this case, load-bearing capacity is a problem and an increase in load-bearing capacity is desired, and if a main member with a T-shaped cross section is used, the width of the back side is 1 to 1.
Because it is supported by a 2mm edge, when used as an entrance mat, there is a risk of damaging floors finished with concrete or linoleum. It had drawbacks such as penetrating into asphalt.

(Means to Solve the Problems) The present invention was made to solve the above problems, and mainly consists of a vertical strip made of metal such as a stainless steel plate and having a rectangular top plate at the top. In a grating where the main member is assembled using secondary members such as bolts, nuts and spacers at equal intervals, the top plate of the main member is placed on the front side, then on the back side. This can be solved by arranging and assembling them alternately.

(Embodiment) The present invention will be explained according to the embodiment shown in the drawings.As shown in Figs. The cross-sectional shape is T.
In a grating whose main members are assembled in a screen shape using bolts 3, nuts 4, spacers 5 for keeping the main members at regular intervals, etc., the top plate portion 2 of the vertical strip 1 is the main member. It is assembled by arranging the front side and then the back side alternately. Note that the gap between the rectangular top plate parts 2 arranged on the front side of the main member is made to be almost the same as the width of the top plate part 2, and the width of the top plate part 2 is divided into two by It is desirable to arrange them so that the main member, which will become the top plate, faces on the side. In addition, the vertical strips of the main member have strips narrower than the strips of the top plate part 2 at the bottom, as shown in cross-sectional view A of FIG. As shown, the thin plate is bent and formed.
Similarly, a pipe molded into a T-shape as shown in D may be used, and any shape may be used as long as it is a vertical strip with a rectangular top plate formed at the top.

In addition, as shown in Fig. 4, a locking hole 6 is bored in the vertical strip 1 of the main member, and locking grooves 8, 8 that engage with the locking hole 6 in the shape of a bar are carved at equal intervals. There is no problem in assembling the members in place of the bolts 3, nuts 4, and spacers 5 in the form of a grid, and if necessary, attaching them by welding a side plate around the assembled grid-like grating. There is no problem.

(Effects of the invention) Since the present invention is constructed as described above, the vertical strips of the main member are arranged narrowly at intervals compared to conventional products, and the load-bearing strength is lower than that of conventional products. It can be fully used as a gutter cover for vehicles to enter and exit, and since there is a top plate on the bottom for support, it can be used on soft soil or asphalt surfaces without damaging concrete, linoleum, or other flooring materials. Even if a facility is established, there will be no fear of encroachment. Furthermore, even if leaves or the like get into the space between the main members, there is no risk of them falling into the grooves and being deposited in the grooves.

Furthermore, since the front side and the back side have the same shape, it can be used without any difference between the front side and the back side.
