Post-Installed Sleeve Device For Compensating Loss Of Shear Capacity

A sleeve device for compensating loss of shear capacity of a concrete slab due to a hole drilled in said concrete slab, said sleeve device comprising:

• a hollow member inserted into said drilled hole, said hollow member comprising a threaded upper section extending above a top surface of said concrete slab;
• a lower ring member comprising an inner edge rigidly attached to a bottom edge of said hollow member;
• and
• an upper ring member comprising an inner threaded edge engageably connected to said threaded upper section of said hollow member, wherein said upper ring member and said lower ring member are configured to sandwich said concrete slab surrounding said drilled hole therebetween for compensating said loss of said shear capacity of said concrete slab due to said drilled hole.

A method for compensating loss of shear capacity of a concrete slab due to a hole drilled in said concrete slab, said method comprising:

• providing a sleeve device comprising:
• a hollow member comprising an upper section;
• a lower sandwich member comprising an inner edge rigidly attached to a bottom edge of said hollow member;
• and
• an upper sandwich member comprising an inner edge engageably connectable to said upper section of said hollow member;
• inserting said hollow member of said sleeve device into said drilled hole of said concrete slab to rigidly contact an upper surface of said lower sandwich member of said sleeve device with a lower surface of said concrete slab, wherein said upper section of said inserted hollow member extends above a top surface of said concrete slab;
• engageably connecting said inner edge of said upper sandwich member of said sleeve device to said upper section of said inserted hollow member;
• and
• sandwiching said concrete slab surrounding said drilled hole by said upper sandwich member and said lower sandwich member of said sleeve device for compensating said loss of said shear capacity of said concrete slab due to said drilled hole.
