Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching a lattice to a horizontal frame such as a surface lattice.

Generally, when using a pipe-shaped lattice, it is undesirable in terms of appearance for the open end surfaces of the lattice to be exposed. As a means of preventing such exposure of the openings, it is conceivable to attach a cap to the end face of the grating, but attaching a cap to each grating is disadvantageous in terms of installation and manufacturing costs. Therefore, from this point of view, it is preferable to cover the end faces of the lattice with horizontal frames that support the lattice. On the other hand, screws are usually used to connect the lattice and the horizontal frame, and when the lattice is formed from an extruded metal material, it is convenient to use screw holes in the longitudinal direction that can be formed simultaneously with extrusion. Then, since this screw hole opens to the end face of the lattice, the screw itself will also be screwed into the lattice longitudinal direction. and,
When installing with screws in this way, it is better to have as few screws as possible, and if possible, it is desirable to support the grid with one screw, and it is also preferable that the head of this screw is not visible from the outside of the building. is good.

The present invention was developed in consideration of the above points, and involves covering the end faces of the grid with a horizontal frame and enabling the grid to be supported with only a single screw. The structure of this device is explained below based on one embodiment shown in the figures.

Figure 1 shows the appearance of a part of the surface lattice.
In the figure, 1, 1 are left and right vertical frames, 2, 2 are upper and lower horizontal frames installed between the vertical frames 1, 1, and between these upper and lower horizontal frames 2, 2, a large number of grids 3 are installed. , 3... are installed in parallel.

Figures 2 and below show the mounting structure on the upper end side of the grid 3. The horizontal frame 2 forms a folded part 5 which is formed by folding the outer side edge of the building of the strip main body 4 upward into a U-shape, and the inner side edge thereof has a folded part 5 that hangs downward from the lower surface near the end. A supporting piece 6 having an L-shaped cross section is formed to protrude toward the upper end of the lattice 3, and includes a vertical portion 6a and a horizontal portion 6b protruding inward from the lower end of the vertical portion 6a. Note that this horizontal frame 2 is integrally formed by metal extrusion or the like.

On the other hand, the lattice 3 has a square pipe shape integrally formed by extrusion molding or the like like the horizontal frame 2,
A longitudinal screw hole 7 integrally formed at the time of extrusion molding is provided on the inner surface on the inner side of the building. The end face of the lattice 3 forms a cutout step 8 which is cut off at a substantially right angle on the screw hole 7 side, that is, on the inside of the building.

In the above, the L-shaped support pieces 6 formed on the horizontal frame 2 and the stepped portions 8 of the lattice 3 are in contact with each other, and while they are brought into contact with each other,
When one screw 9 inserted from above the horizontal part 6b of the support piece 6 is screwed into the screw hole 7 of the lattice 3 to fix the lattice 3, the lattice 3 is fixed to the step part 8 and the support piece. Since the screws 6 are in contact with each other, even if there is only one screw 9, the screw 9 can be supported without rotating in the horizontal direction. In addition, the main body 4 of the horizontal frame 2,
There is a gap 1 between the uncut end face of the grid 3.
0 is left behind so that the main body 4 covers the end face of the grid 3 like an eave.

The present invention has the above-described configuration. According to the present invention, since the end faces of the lattice are covered with the horizontal frames, the end faces of the lattice are not exposed, and furthermore, the horizontal frames and the end faces of the lattice are mutually connected. Since the abutting notch steps and supporting pieces are provided, the grid is prevented from turning around, and therefore the grid can be supported with a single screw. Furthermore, since the screws mentioned above are inserted and fixed into the horizontal part of the L-shape, the heads of the screws are located below the top and bottom surfaces of the horizontal frame, and therefore the support pieces can be positioned inward of the building. For example, it will not be visible from the outside of the building, resulting in a better appearance.
