Reinforcement system for increased lateral stability of wall
View Patent ↗Reinforcement system for concrete panel wall, such as I-type flood wall, includes high tensile strength textile attached to wall by adhesive and reinforced by mechanical fasteners. Most preferred embodiment comprises a strip of fiber reinforced plastic spanning multiple panels, with the grain of the textile material extending horizontally. Alternative embodiment includes vertical FRP with bias-grain textile. Fasteners are preferably ductile fiber anchors.
1. In combination:
a wall including:
a plurality of upright panels; each said panel including:
an outer face;
an inner face opposite said outer face;
two ends;
a lower edge;
an upper edge;
said panels being connected end to end; and
an expansion joint disposed between and connecting adjacent ends of said panels; and
a reinforcement system to strengthen said wall, comprising:
a first strip of sheet material adhesively attached horizontally along the length of said wall such that said strip is attached to a portion of one of said outer and inner faces of each of said plurality of panels, said first strip of sheet material covering but not adhesively attached to said expansion joint.
2. The combination of claim 1 , said attached first strip of sheet material comprising:
a length of fabric woven from yarns of suitable strength and durability; disposed between said lower and upper edges such that the grain of said length of fabric is parallel to said upper edge.
3. The combination of claim 1 , said reinforcement system further including:
a plurality of mechanical fasteners attaching said first strip of sheet material to said panels.
4. The combination of claim 1 , said first strip of sheet material being not adhesively attached to said one of said outer and inner faces of at least one said panel near said expansion joint such that said first strip of sheet material includes:
an unbonded portion covering said expansion joint; said unbonded portion being sufficiently wider than said expansion joint such that said unbonded portion can stretch sufficiently to accommodate flexing of said joint due to thermal expansion and contraction of said panels connected to said expansion joint.
5. The combination of claim 1 , further including:
a second strip of sheet material vertically spanning the joint between a first said panel and a second said panel; said strip attached to a portion of one said face of said first panel and a portion of one said face of said second panel and comprising:
a length of fabric woven from yarns of suitable strength and durability; disposed such that the vertical centerline of said length of fabric is parallel to said expansion joint and the grain of said fabric is an angle of 20 to 70 degrees from parallel to said expansion joint.
6. In combination:
a wall including:
a plurality of upright panels; each said panel including:
an outer face;
an inner face opposite said outer face;
two ends;
a lower edge; and
an upper edge;
said panels being disposed end to end; and
expansion joints connecting adjacent pairs of panels, each said expansion joint being disposed between one said end of a first said panel and the adjacent said end of an adjacent second said panel for resiliently sealing the gap between said panels; and
a reinforcement system to strengthen said wall, comprising:
a first strip of sheet material vertically spanning the gap between a first said panel and a second said panel; said strip attached to a portion of one of said outer and inner faces of said first panel and a portion of one of said outer and inner faces of said second panel; said strip covering but not attached to said expansion joint between said first and second panels, such that said attached strip does not interfere with the function of said expansion joint.
7. The combination of claim 6 , said first strip of sheet material attached to said one of said outer and inner faces of each said panel by a suitable adhesive; but not attached to said expansion joint.
8. The combination of claim 6 , said first strip of sheet material comprising:
a length of fabric woven from yarns of suitable strength and durability; disposed such that the vertical centerline of said length of fabric is parallel to said expansion joint and the grain of said fabric is at an angle of 20 to 70 degrees from parallel to said expansion joint.
9. The combination of claim 6 , said reinforcement system further including:
a second strip of sheet material attached horizontally along the length of said wall such that said strip spans at least a portion of each of said plurality of panels.
10. The combination of claim 9 , said second strip of sheet material attached to said one of said outer and inner faces of each said panel by a suitable adhesive; but not attached to said expansion joint and not interfering with the function of said expansion joint.
11. The combination of claim 9 , said second strip of sheet material comprising:
a length of fabric woven from yarns of suitable strength and durability; disposed between said lower and upper edges such that the grain of said length of fabric is parallel to said upper edge.
12. The combination of claim 9 , said reinforcement system further including:
a plurality of mechanical fasteners connecting said second strip of sheet material to said panels.
13. In combination:
a wall including:
a first panel including:
a first end;
an upper edge; and
a lower edge;
a second panel including:
a second end;
an upper edge; and
a lower edge;
said first panel and said second panel disposed with said first end and said second end opposed and close to each other; and
an expansion joint disposed between said first and second ends and connecting said ends together; and
a reinforcement system for increasing the lateral stability of said wall, including:
at least one sheet of textile material adhesively attached to both said first panel and said second panel and not attached to said expansion joint.
14. The combination of claim 13 , said at least one sheet of textile material comprising:
a sheet of fabric woven from yarns of suitable strength and durability; disposed between said lower and upper edges such that the grain of said length of fabric is generally parallel to said upper edges of said panels.
15. The combination of claim 13 , said at least one sheet of textile material comprising:
a first sheet of fabric woven from yarns of suitable strength and durability; disposed such that the grain of said fabric is at an angle of 20 to 70 degrees from parallel to said expansion joint.
16. The combination of claim 15 , said at least one sheet of textile material further including:
a second sheet of fabric woven from yarns of suitable strength and durability; disposed between said lower and upper edges such that the grain of said length of fabric is generally parallel to said upper edge.
17. The combination of claim 13 ; wherein said at least one sheet of textile material comprises: at least one panel of fiber-reinforced plastic.
18. The combination of claim 13 ; said reinforcement system further including:
a plurality of mechanical fasteners for attaching said at least one sheet of textile material to said first and second sections.
19. The combination of claim 13 , said sheet of textile material being not adhesively attached to said first and second panels near said opposing first and second ends of said panels, such that said attached sheet of textile material includes:
an unbonded portion covering said expansion joint; said unbonded portion being sufficiently wider than said expansion joint such that said unbonded portion can stretch sufficiently to accommodate flexing of said joint due to thermal expansion and contraction of said first and second panels connected by said expansion joint.
