Title: Corner reinforcing member
Inventor: CHIKAMORI SEISHI
IPC: E04F19/06
Filed: 2001-02-09
Abstract: PROBLEM TO BE SOLVED: To solve problems on a conventional corner reinforcing member which is hard because of being made of vinyl chloride or aluminum, and as a result, it is incompatible with a wall material, easy to break and not usually used for an internal corner. SOLUTION: This corner part reinforcing member 1 is a sheet-like member previously bent in two at an angle θ and provided with a large number of regularly opened holes 2. An adhesive is previously applied to the plane side which is in contact with a wall, and a seal may be stuck thereon. The sheet-like corner part reinforcing member 1 is composed of polypropylene spanbond nonwoven fabric, and the tape-like nonwoven fabric is formed in a suitable length and bent in two at the angle θ. This results in realizing the corner part reinforcing member compatible with the wall material, hard to break, positively securing vertical and horizontal lines and improving work efficiency. The corner part reinforcing member for the internal corner can also be realized.
