TRUSS TYPE (MR1)
BUILDING ACCESSORIES
Description

. MR2 type is a prefabricated reiforcement especiallydesigned for embedment in the horizontal mortar joints of masonry, . It ismanufactured in 10 ft, length. Ladder type consists of two or more parallel, longtidunal rods weld connected to perpendicular cross rods normally spaced 15" O.C. to form a ladder design. For reinforced amsonry applications, 16" spacing is available on request. The cross rods are electricaly butt Yielded side rods in a single plane. Out to out sapcing of side is approximately two inches less than the nominal thickness of the wall or wythe in wich the reinforcement is placed.

Basic Uses
MR1 truss reinforcement Is used in a number of applications to improve the performance of masonry walls.
Some are:
  • To control shrinkage cracking.
  • To provide principal horizontal reinforcement in engineered masonry walls.
  • To bond masonry wythes together in composite and cavity walls.
  • To reinforced stack bond masonry.
  • To bond intersecting walls.
Advantages

Tests show that continuous reinforcement improves the performance of walls by providing:
  • Crack control
  • Greater elasticity
  • Higher ductility
  • Better resistance to rain penetration
  • More construction economy

Prefabricated Corners and Tees

  • . A complete line of prefabricated corner and tee sections are available in all design types and finishes.
  • . It is necessary to designate corners as inside or outside when using trirod or double design types.
