Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grating assembled in a lattice shape used for gutter covers, entrance mats, etc.

[Conventional technology]

Traditionally, grating used for gutter covers, entrance mats, etc. consists of narrow metal strips arranged in parallel and at equal intervals, and strips or rods arranged perpendicularly to the strips. etc. as secondary parts and welded by electric pressure welding method etc., or provide locking grooves or locking holes in the main and secondary parts and assemble them in a lattice shape, and if necessary, the end faces of the surrounding main and secondary parts. It is manufactured by fixing the side plate to the
This main member has been made of a material having an I-shaped cross-section, a T-shape, an inverted L-shape, or the like in cross section.

[Problem that the invention attempts to solve]

As mentioned above, since the assembled grating is made of metal, long lengths are heavy, and for convenience in storage, transportation, installation, etc., predetermined dimensions, e.g.
They are manufactured in fixed lengths such as 50cm and 100cm.
Therefore, in the case of gutter covers, etc., a large number of gratings are constructed so that they are in continuous contact with each other in the required number.
In consideration of expansion during the summer, gratings are installed with appropriate gaps between them, so when the gratings move due to vehicles passing by, the gaps between the gratings sometimes disappear or become wider. Also, when used as a doormat, it is generally fine as it can be installed on a flat area, but when grating is used as a passageway for metal pine and is laid on a slope or a place where the whole area is undulating, it is necessary to use multiple pieces of small-area grating. It was dangerous if it shifted or if you stepped on the edge, the other side would float up. In addition, the lighter the weight of these gratings to handle, the more convenient it is for cleaning gutter covers, etc., but as mentioned above, if the grating shifts and there is no gap, it may float at the contact part due to expansion. It may become dangerous due to leakage or widening of the gap, or it may be left unattended without being removed.
Because of the risk of theft, it was necessary to take measures such as fixing the gratings to the receiving frame of the groove using bolts or using special connecting fittings to connect the gratings.

[Means for solving problems]

In the connecting grating of the present invention, when the main members are arranged in parallel, the gap between the main members is wider than the width of the main member, and the sub members at the ends of the main members are rod-shaped sub members. The bar-shaped secondary member is removed and the ends of the main member are connected to the adjacent connecting gratings in a gear-shaped manner. The locking holes at the ends are aligned, and the rod-shaped sub-members are inserted into the locking holes to create a long grating, or connecting gratings with rod-shaped sub-members attached in advance are lined up and placed adjacent to each other. The rod-shaped secondary members of the grating are connected using a connecting fitting such as an annular fitting to form a long grating.

〔Example〕

The present invention will be explained according to embodiments shown in the drawings.

As shown in FIG. 1, the main member 3 of the connecting grating of the present invention is provided with locking holes 4, 4 at both ends thereof, so that the main members 3 are arranged in parallel and the distance between them is wider than the width of the main member 3. The main members 3, 3, . The rod-shaped secondary member 6 inserted into the locking holes 4, 4 bored at both ends is removably attached using a bolt or the like that can be screwed with a nut at the end, or the rod-shaped secondary member 6 is inserted into the locking holes 4, 4 drilled at both ends. will be prepared.

The locking hole 4 drilled in the main member 3 should be larger than the diameter of the sub-member 6 and preferably circular or oval, but if the main member 3 is rotatable around the rod-shaped sub-member 6, The main part 3 can be used in any shape.
The cross-sectional shape normally used for assembling gratings can be I-shaped, T-shaped, inverted L-shaped, etc.

In addition, if it is used for a groove cover and a load capacity is required, the distance between the sub-members may be made small, or the intermediate sub-member 5 may be made of a material with a high load capacity.

[Effect of idea]

First, to describe the method of assembling the connecting grating according to the present invention, the rod-shaped secondary member 6 inserted into the locking holes 4, 4 bored at both ends of the main member 3 of the connecting grating is removed, and the adjacent The ends of the main member 3 of the connecting grating are meshed with each other like gears, and the locking holes 4, 4 drilled in the ends are aligned, and the removed rod-shaped sub-member 6 is locked. hole 4,4
If you connect the grating by inserting it into the second
As shown in the figure, a long grating of arbitrary length can be obtained. As shown in FIGS. 1 and 2, when the main member 3 is arranged between the connecting gratings 2 with one less main member 3 and the connecting grating 1 with one more main member 3, the rod-shaped sub-member 6 that can be inserted can be inserted. It can be fixed to the main members at both ends by welding, etc., but even if the main members have the same number of connecting gratings, the main members have different lengths, that is, connecting gratings with different lengths are used alternately. There is no problem.

Also, a connecting fitting 7 or 7' as shown in FIG.
By using the connecting gratings 1, 1 as shown in FIG. 4, a long grating of arbitrary length can be obtained. In this case, the connecting fitting may have the same shape as the main member 3 and have locking holes at both ends.

As described above, the long grating assembled using the connecting grating according to the present invention is
Since rod-shaped bodies are used for the secondary members 6 at both ends, each connected unit grating can be bent and folded using the secondary members 6 as an axis, and bolts and nuts can be used for the secondary members 6. As a result, gratings of any desired length can be assembled on site, and even if the grooves are slanted or wavy, they can be installed without any problems. In addition, since the locking holes 4, 4 drilled in the main member 3 and the locking hole 4 of the connecting fitting 7 are drilled so as to be larger than the diameter of the rod-shaped secondary member 6, the grating does not heat up in the summer. Even if the grooves are not straight and are slightly bent, the diameter of the locking hole 4 of the main member 3 and the diameter of the secondary member 6 can be adjusted without worrying that the expansion will be absorbed and float up in a mountain shape between the gratings. Since it can be bent within the range of the difference between It has the advantage of being able to
