Douglas Fir is more prone to splitting than other softwood species, therefore requires larger spacing requirements.
The Yoke anchors can be used to lift Glue Laminated Timber (GLT), Nail Laminated Timber (NLT) and Dowel Laminated Timber (DLT) panels.
When designing connections with internal knife plates using our Self-Drilling Dowels, there are a few important details to keep in mind to make sur...
For optimum torque transfer in addition to exceptional fit and durability.<br>
Yes, two beam hangers may be installed vertically on top of each other.
Fully threaded self-tapping screws are optimized for axial loading. By sufficiently inclining the screws toward the line of the force, lateral conn...
Impact Drills cause a torque differential to the ASSY self-tapping screws, which causes permanent damage to the screw during installation.
Regular ASSY® carbon steel screws are intended for use in dry service conditions only, while corrosion-free ASSY® A2 stainless steel screws are sui...
Deep beams paired with smaller Ricon S VS beam hangers can experience out-of-plane twisting when not restrained properly.
Calculated axial capacity design values for ASSY self-tapping screws must be compared against all other possible failure modes.
The inclination of the screw axis with respect to the grain orientation, it can make it confusing to determine the spacing requirements of a connec...
The structural integrity of deep timber elements can be affected by the swelling and shrinking of the elements associated with changes in moisture ...
The Beam Hanger System can be used in CLT end grain applications.
Challenges with site access or equipment limitations may force the installer to stop and drive the ASSY screws in multiple runs.
The use of fire caulking is up to the discretion of the designer.
Wood members expected to have high moisture contents need to be designed for wet service conditions.
Certain T-joint connections may be required to resist tensile loads.
Tension-site notches can result in excessive tensile stresses acting perpendicular to the grain of the panel.
Inclined screws can be arranged mutually parallel to one another or in symmetrical screw crosses.
“Trust, but verify.”
As inclined shear-tension screws are loaded primarily in tension along the axis, even load-sharing is promoted through even pre-tensioning.
Ductility in timber structures comes primarily from mechanical joints.
The majority of the time, self-tapping screws are installed with no pre-drilling. However, for some applications it is helpful to pre-drill a hole.
Standard design procedures in CSA O86 and NDS 2018 account for strength reductions associated with end grain installation, but member strength must...
Dependent on installation location reinforcement of connector plates is required in order to maintain continuous shear transfer in the connected me...
If an inclined shear-tension screw and an inclined shear-compression screw are far apart, do they still function as a screw cross?
When loaded in tension, the withdrawal resistance of a fastener may be adjusted to short term loading, can the tensile strength be adjusted as well?
Full body fasteners have a shank diameter that is equal to the outside thread diameter of the threaded portion.
For connecting a 6-⅞” by 21” beam to a column.
For symmetrical installation of RICON pre-engineered connectors application can often be limited by the width of the member resulting in fastener c...
