Diagonal flexible ties INFIX

CJSC «The Republican Chamber of Entrepreneurs» produces and sells flexible ties. They are made of composite materials. The enterprise has own production facilities, uses patented equipment and own design technology.

Applications

Diagonal flexible ties INFIX™ are used in production of sandwich-panels and for joining all layers of the panels. They are intended to replace similar steel products. They have similar anchoring parameters and stronger then steel products, lighter in 4, have lower thermal conduction in 30. They are resistant to corrosion and have a low price.

Design

Diagonal flexible tie INFIX™ are two parallel rods of a plain profile, fastened by a zig-zag rod of a periodic profile.

Conclusions of physical and mechanical tests

  1. The tensile strength was 1603 MPa, corresponds to requirements p. 5.1.4 GOST R 54 923−2012, not less than 1000 MPa.
  2. The influence of alkaline medium on the samples of flexible ties was studied:
    a) 0,01 N 1000 h, t 20C
    b) 1 N 120 h, t 95C
  3. Residual the tensile strength after ageing in alkaline medium 0,01 N was 89%.
  4. Residual the tensile strength after ageing in alkaline medium 1 N was 77,62%.
  5. The tensile of flexure was 1083 MPa, corresponds to requirements p. 5.1.4 GOST R 54 923−2012, not less than 1000 MPa.
  6. Residual the strength of flexure after ageing in alkaline medium 0,01 N was 89,17%.
  7. Residual the strength of flexure after ageing in alkaline medium 1 N was 84,19%.

Advantages

  1. Effective joining of all layers concrete sandwich-panels with high thermal insulating specifications.
  2. Saving of time, number of employees and equipments. Lightweight constructions.
  3. Simplicity of erection between of layers insulation.
  4. Accretion of working efficiency and lowering of time to manufacture the panel.
  5. Sizes according to the depth of the insulation material.
  6. Endurance of construction, low costs for service.
  7. Flexible ties are resistant to alkaline medium of concrete.
  8. Energy — saving. The composite material has a low thermal conduction. So, there are no «cold bridges» in walls.
  9. Debugged production work guarantees reliability and the high quality of productions.
