HECO-TOPIX ®-CombiConnect HECO-TOPIX ®-Therm HCS-Calculation software THE WOOD SCREW FOR THE PROFESSIONAL The HECO-Calculation software (HCS) and HECO-TOPIX ® Woodscrews for easy estimation and safe assembling of on-rafter insulations and timber constructions

The HECO-TOPIX ®-CC screw for load transmission at the highest level! With the HECO-TOPIX ®-CombiConnect you have available a power screw for the most varied range of applications: Transverse butt joints Rafter-purlin joints Doubling up of weak wooden beams Transmission of considerable compressive forces Reinforcement of weak points in the cross section of classic timber joints 1. Transverse butt joints Clamping effect, the structure is pulled together by up to 5 mm Higher degree of load transmission Rational working procedures – industrial production – modern timber construction! In recent years,...

3. Reinforcement of weak points in the cross section of classic timber joints Traditional carpenter’s joints are susceptible to considerable cross sectional weaknesses. Whether tenon joints, dovetail joints or common halvings – the cross section of these joints can be reduced without decreasing the load bearing capacity (see transverse butt joints). Nevertheless, if a traditional joint is still required, you have the option of using simple tenon joints to transmit the transverse pull! Higher degree of load transmission Transmission of transverse pull Fasteners not visible Fast, cost-saving working...

4. Doubling of weak wooden beams The entire construction sector is attaching more and more importance to building in existing stock. Nevertheless, reducing costs is still of the utmost priority. Existing timberwork is often well preserved in the building structures but not adequately dimensioned for focused load application of the new structure. Previously, the only option in such cases was the removal of the weak timber beam. Higher load acceptance from the supporting structure Fast, cost-saving working procedures removal of existing building stock No Fasteners not visible High fire resistance...

6. Transmission of considerable compressive forces Higher degree of load transmission Slender cross sections and high loads – time and time again, this arrangement poses problems in timber construction applications. Although the slender, visually appealing component can take up the necessary compressive forces, it would press too much into the supporting beam. This results in an increase in the cross section or the need for a steel component with large-area load transmission. The HECO-TOPIX®-CC screw renders bulky, oversized cross sections or steel components unnecessary. When screwed in, the...

The HECO-TOPIX ® fastening system for building insulation. Facade or roof insulation with perfect energy efficiency! The method of fastening soft insulating materials for facade and roof insulation poses a specific problem: how are the applied compressive and shear loads transmitted and how is the material secured reliably but with the least possible effort? HECO® solves these problems professionally, efficiently and fast. Low-strength insulating materials cannot transmit compressive loads such as the weight of the roof covering or snow loads. For this reason, HECO® has developed the new HECO-TOPIX®-Therm....
