FRP Fiber Reinforced Polymer Truss
Used in the production of reinforced concrete three-layer wall panels, it is designed to connect the panel layers to each other. It is applied to replace similar products made of steel while increasing the thermal performance of the panel by 20%
Cheaper than the metal analog!
Composite FRP Trusses are significantly cheaper than traditional steel shear connectors
Fiber Reinforced Polymer design
FRP Truss is a product consisting of two guide rods — composite parallel rods of deformed section — fastened together with composite zigzag-shaped rods by means of polymer locks
H - height of the FRP Truss; L - length of the FRP Truss; l - wave pitch of the FRP Truss diagonal rod; R - bending radius of the FRP Truss diagonal rod; d - diameter of the FRP Truss rods; h - distance between the FRP Truss guide rods
Properties of Fiber Reinforced Polymer Truss
Not afraid of chemical attack and moisture, that affects the durability of the materials usage and the possibility of their application at any time of the year
Corrosion and chemical resistance
Tensile strength of composite rods and mesh is 3 times higher than its steel counterpart
Tensile strength
Does not conduct electricity or interfere with cell phone and internet signal propagation
Dielectric, no radio interference
Does not form thermal bridges — this improves the thermal insulation parameters of the construction object
Low thermal conductivity
Even at severe frosts composite rebar does not lose its properties. Temperature threshold of operation ranges from -70°C to +100°C
Heat resistance
Lack of welding simplifies installation — any worker with a minimum set of tools can handle the binding of rebar
Easy to install
The shear strength of composite mesh rods is the same as its steel counterpart
Shear strength
What challenges do thermal bridges pose:
Solves the thermal bridges issue
Condensate formation
Condensation leads to the appearance of mold in apartments, which harms the health of residents, and worsens the appearance of the home
Thermal bridges are local areas of a building through which higher heat transfer occurs. Typical thermal bridges are metal joints, window and door lintels, etc.
Increased energy costs
Precious heat escapes through thermal bridges, so heating costs for the building increase by about 30%
Reduced safety
Thermal bridges lead to cracks, reduced load-bearing capacity of the structure, resulting in higher building maintenance costs
Test technical documentation
FRP Truss testing
We tested a three-layer exterior wall sandwich panel made with FRP Truss. The following results were obtained:
Ultimate tensile strength over 1532 MPa
This index meets the requirements of 5.1.4 clause of GOST R 54923-2012 — not less than 1000 MPa
Residual ultimate tensile strength ranging from 77% to 89%
The residual tensile strength after soaking in 0.01 H sodium hydroxide alkaline medium is 89.00%, after soaking in 1 H sodium hydroxide alkaline medium — 77.62%
Maximum load values ~ 5 times the reference strength load
Shear tests showed that the maximum load is 5.88 times the reference strength load, and after a 24-hour fire exposure — 4.77 times the reference strength load. No cracks or signs of panel deterioration were observed
Fire resistance limit not less than REI 60
Fire resistance limit of sandwich panel with FRP Truss of our production is not less than REI 30
