The groove is a recessed groove, and the opening side wall 11 is fitted into the lip groove 9 protruding from the edge of the opening of the groove.
Further, as shown in FIG. 2, the locking plate 5b of the metal fitting 5 is formed wider than the opening 10 of the lip groove 9, and the locking plate 5b and the side wall 11 of the opening of the concave lip groove 9 are formed. To prevent the support bar 2a from falling off the surface lattice support fitting 5. Therefore, when the surface lattice 2 is attached to the window opening 4, first, one end 5a of the metal fitting 5 is fixed to the building frame 3 with the locking plate 5b of the metal fitting 5 fitted in the lip groove 9. Next, the surface lattice 2 is appropriately horizontally moved along the lip groove 9 to adjust the positional relationship between the surface lattice 2 and the metal fitting 5, whereby the surface lattice 2 is attached to the window opening 4. It can be positioned to suit the conditions.

Further, the locking screw 13 is screwed into the screw hole 12 penetrating the locking plate 5b of the above-mentioned surface lattice support fitting 5, and as described above, the surface lattice 2 is set as the condition for attaching the surface lattice to the window opening 4. After positioning so as to adapt, the locking screw 13 is fastened and the tip of the screw 13 is pressed against the bottom surface 14 of the lip groove 9 to open the locking plate 5b of the metal fitting 5 in the opening of the lip groove 9.
