OBJECTIVE DURING THIS TOPIC YOU WILL GAIN AN UNDERSTANDING OF……. REASONS FOR REINFORCING BRICKWORK METHODS OF REINFORCING BRICKWORK POSITIONING REINFORCEMENT OVER OPENINGS SPECIAL BRICK BONDING ARRANGEMENTS POCKET REINFORCEMENT DAVIDFCOOKE@GMAIL.COM 2

Slide 3

INTRODUCTION IN GENERAL BRICKWORK IS SUFFICIENTLY STRONG TO CARRY LOADS BEARING DIRECTLY DOWN ON IT. WHEN A LOAD SUCH AS A FLOOR IS RESTING ON A WALL – THIS IS CALLED A COMPRESSIVE LOAD. 3 DAVIDFCOOKE@GMAIL.COM

Slide 4

BRICKWORK IS STRONG WHEN IN COMPRESSION (JUST LIKE CONCRETE) 4 DAVIDFCOOKE@GMAIL.COM Image Source: BDA Successful Brickwork Pg 99

Slide 5

WHEN BRICKWORK IS SUBJECT TO LATERAL LOADS SUCH AS WIND – IT IS WEAK & REQUIRES REINFORCING. 5 DAVIDFCOOKE@GMAIL.COM Image Source: BDA

Slide 6

SO… BRICKWORK IS STRONG IN COMPRESSION BUT WEAK IN TENSION. 6 DAVIDFCOOKE@GMAIL.COM  x

Slide 7

METHODS OF REINFORCING THE MOST COMMON METHODS USED TO REINFORCE BRICKWORK INCLUDE………… WIRE REINFORCING STEEL ROD REINFORCING SPECIAL BRICK BONDING ARRANGEMENTS POCKET REINFORCED BRICKWORK 7 DAVIDFCOOKE@GMAIL.COM

Slide 8

WIRE REINFORCING THE USE OF MASONRY REINFORCEMENT IS A VERY SIMPLE AND COST-EFFECTIVE WAY OF GREATLY ENHANCING THE STRENGTH AND DURABILITY OF BRICK CONSTRUCTION IT PROVIDES BOTH STRUCTURAL AND CRACK CONTROL BENEFITS. 8 DAVIDFCOOKE@GMAIL.COM

Slide 9

WIRE REINFORCEMENT BENEFITS INCLUDE….. BONDS AND STRENGTHENS CORNERS AND WALL INTERSECTIONS. RESISTS CRACKING IN AREAS OF UNEVEN SETTLEMENT. BONDS WALLS TO REINFORCED CONCRETE FRAMES. 9 DAVIDFCOOKE@GMAIL.COM

Slide 10

EASY FOLDING FOR CORNERS, CURVES AND ANGLES. SAFE TO HANDLE AND EASY TO CUT AND SHAPE ON SITE. 10 DAVIDFCOOKE@GMAIL.COM

Slide 11

THE MOST COMMON TYPES OF WIRE REINFORCING INCLUDE…….. BRICKFORCE BRICKTIE BRICKTORE OR MESH WALLFORCE 11 DAVIDFCOOKE@GMAIL.COM

Slide 12

BRICKFORCE TWO MAIN PARALLEL WIRES JOINED BY IN-LINE WELDED CROSS WIRES. MAIN WIRES ARE MANUFACTURED TO A FLATTENED PROFILE TO SIMPLIFY LOCATION INTO THE MORTAR JOINT WITHOUT STEEL BUILD-UP PROBLEMS AT LAP POSITIONS CORNERS/JUNCTIONS OR WHEN USED IN CONJUNCTION WITH WALL TIES 12 DAVIDFCOOKE@GMAIL.COM

Slide 14

BRICK TIE AVAILABLE IN WIDTHS TO SUIT ANY REQUIRED WALL MAKE UP. THE MOST COMMON FORM IS 175MM WIDE TO SUIT A 215MM COLLAR-JOINTED WALL CONSTRUCTED FROM TWO LEAVES OF 100MM. BY TYING THE TWO LEAVES TOGETHER, THE WALL MAY BE DESIGNED AS IF IT WERE SOLID CONSTRUCTION. 14

Slide 16

BRICKTOR OR MESH BRICKTOR OR MESH IS MANUFACTURED FROM HIGH TENSILE WOVEN WIRE AVAILABLE IN STAINLESS STEEL AND GALVANISED FINISHES IT LIES FLAT ON THE MORTAR BED JOINT MAKING THE PRODUCT EASY TO INSTALL COMPARED TO OTHER COILED PRODUCTS. 16 DAVIDFCOOKE@GMAIL.COM

REINFORCEMENT OVER OPENINGS 20 DAVIDFCOOKE@GMAIL.COM

Slide 21

STEEL ROD REINFORCING IN THIS TYPE OF REINFORCING, STEEL RODS ARE PLACED WITHIN A CAVITY THE CAVITY IS THEN FILLED WITH EITHER MORTAR OR A CONCRETE GROUT. THIS BINDS THE RODS TO THE BRICKWORK GIVING LATERAL STRENGTH TO THE WALL 21 DAVIDFCOOKE@GMAIL.COM

Slide 24

SPECIAL BRICK BONDING ARRANGEMENTS ALTHOUGH NOT A COMMON METHOD OF CONSTRUCTION DUE TO THEIR AWKWARDNESS & DURATION TO BUILD, THE TWO BRICK BONDING ARRANGEMENTS BEST SUITED TO REINFORCING BRICKWORK ARE…….. QUETTA BOND RAT TRAP BOND 24 DAVIDFCOOKE@GMAIL.COM

Slide 25

STEEL RODS ARE INSERTED WITHIN THE POCKETS OF THESE WALLS THE POCKETS ARE THEN FILLED WITH MORTAR OR CONCRETE WHICH SURROUNDS THE STEEL GIVING A BOND BETWEEN THE STEEL AND THE BRICK. 25 DAVIDFCOOKE@GMAIL.COM

Slide 28

POCKET REINFORCED BRICKWORK THIS REINFORCEMENT IS CONTAINED IN THE REAR OF THE WALL. POCKETS ARE LEFT AT THE BACK OF THE BRICKWORK TO ALLOW VERTICAL SECTIONS OF CONCRETE TO BE POURED AROUND STEEL. THIS TYPE OF REINFORCING IS NORMALLY USED IN RETAINING WALLS 28 DAVIDFCOOKE@GMAIL.COM
