Claims

[Scope of utility model registration request]

A projecting strip 3 having an upward step 5 is integrally provided on the main body 2 to form an upper horizontal beam 1, and a projecting strip 8 having a downward step 10 on the main body 7.
are integrally provided with the lower horizontal crosspiece 6, and both side walls 11a, 11
b, both end walls 11c, and lid form a hollow lattice 11.
In addition, a first notch groove 14 into which one end wall 11C of the lattice 11 is tightly fitted is formed in the protruding strip 3 of the upper horizontal beam 1 over the entire height of the lattice 11. A second notched groove 15 into which the other end wall 11d is tightly fitted is formed over approximately half the height of the protruding strip 3, and the other end wall 11d of the lattice 11 is formed in the protruding strip 8 of the lower horizontal beam 6. A fourth notched groove 17 that fits tightly is formed over the entire height of the protruding strip 8, and a third notched groove 16 that tightly fits one end wall 11c of the lattice 11 is formed at approximately half the height of the protruded strip 8. At the same time, an upper notch 13 is formed in the upper part of the other end wall 11d of the lattice 11, and the upper notch 13 is closely fitted with the second notch groove 15, and a third notch is formed in the lower part of the one end wall 11c of the lattice 11. A lower cutout groove 12 is formed which tightly fits into the groove 16, and the grating 1
A connecting device for connecting upper and lower horizontal bars and a lattice, characterized in that both end walls 11c and upper and lower portions 18 and 19 of the lid of 1 are punched out and deformed to engage with an upward step 5 and a downward step 10.
