BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing an embodiment of a structure for assembling a lattice-like structure according to the present invention.

FIG. 1 shows a lattice window 10 for security as an example of a lattice-like structure according to the present embodiment, and a building 20 such as a general house.
FIG. 3 is a perspective view showing an aspect of attaching from the outside to a window frame 22 of an existing or new glass window 21 in FIG. Lattice window 10
Is a rectangle corresponding to the size of the window frame 22, and can be assembled by horizontally arranging the horizontal rails 13 at equal intervals between the vertical rails 11 and 12 on the left and right sides. An attachment stay 16 is provided at each of the uppermost and lowermost horizontal rails 13.
To be fixed to the window frame 22.

FIGS. 2 to 5 show a typical structure in which one of the vertical bars 12 and one end of the horizontal bar 13 is connected to each other. Although the material of the vertical beam 12 and the horizontal beam 13 is not particularly limited here, a material which is generally called aluminum sash or the like, has corrosion resistance and required rigidity, and is lightweight and has good workability can be used.

As shown in FIG. 2, the vertical bar 12 is formed into, for example, an angle bar having an L-shaped cross section. Flattened mortise portions 12b are formed at equal intervals at a coupling pitch with the horizontal rail 13 over the entire length of one side flange 12a of the angle main body. Flat tenon 12b
Are formed in a downward direction by cutting the notches 12c on both sides.

In FIG. 2, the horizontal rail 13 is formed as a polygonal prism having, for example, a trapezoidal cross section.
At both ends of the prism main body 13a, a slit groove-shaped tenon 13b is formed by cutting the upper end of the trapezoidal top downward.
Are formed. The tenon portion 12b on the side of the vertical rail 12 fits snugly into the tenon hole 13b, so that a firm fit can be achieved without shifting in any of the left, right, front and rear directions.

Therefore, at the time of assembling, each of the tenon portions 12b of the vertical rail 12 is dropped so that a plurality of horizontal rails 1
The temporary assembling is performed by being fitted into the third tenon 13b with almost one touch. However, even at the stage of the temporary group, it is in a very strong connection at that stage. FIG. 3 shows this temporary assembly state.

Next, similarly in FIG. 3, a stopper cap 14 having a U-shaped cross section having a length equivalent to the entire length of the vertical rail 12 is separately prepared. The entire length of the bar 12 is wrapped inside and covered. Cap 1 for retaining the tenon with the horizontal bar 12
4 to cover the mortise 12b and the tenon 1
3b prevents the tenon from coming off. FIG. 4 shows a shape in which a retaining cap 14 is attached to prevent the mortise fitting portion from coming off, and the mortise fitting portion is covered to provide a decorative fringing appearance.

Subsequently, as shown in FIG.
The main assembly is performed at the stage where the caps 14 are attached to each of the two. In this book set, the upper and lower ends of the rear flanges 14a of the caps 14 on both sides and the upper and lower ends corresponding to the upper and lower ends, respectively, and the rear surfaces of both ends of the two horizontal rails 13 are blind-riveted. Cast at 15 and join. That is, by reinforcing the four corners of the lattice window 10 with the rivet caulking through the caps 14, the rigidity of the entire lattice window is enhanced. As in the case of the cap 14, the caulking of the four corners by the blind rivet 15 is to completely prevent the mortise fitting portion from coming off and to enhance the rigidity of the entire lattice window 10, It is not necessary to carry out at all the joints by fitting. It is to be noted that the cap 14 and the cross rail 1 at the site where such reinforcing rivets are to be driven are set.
3 respectively, a rivet pilot hole (in FIG. 5,
Only the pilot hole 14b provided in the cap 14 is shown).

As described above, a series of assembling operations up to rivet setting at four corners are efficiently performed in a short time, and the completed lattice window 10 is, as shown in FIG. It is easily attached to the window frame 22 from outside for security.

[0020]

As described above, the assembling structure of the lattice-like structure according to the present invention is a structure in which the vertical and horizontal crosspieces are connected by one-touch dropping of the flattened tenon and the slit-shaped tenon. Therefore, the work of manufacturing and assembling the lattice-like structure in a factory or on-site greatly improves the efficiency, greatly shortens the delivery time, etc., and can reduce the material work cost as a whole.
