BRUTUS THREADED ROD

BRUTUS THREADED ROD
BRUTUS — for use in new and existing properties 

High internal stresses occurring in large timber components such as building trusses, for example, often become too great to be absorbed by the timber alone. As timber is relatively weak in the direction perpendicular to the grain, it is particularly at risk due to transverse shear and must be reinforced in such cases. 

BRUTUS threaded rods absorb these transverse-shear forces! 

They are applied both in new constructions (when building the trusses) and in renovations. Whereas in new constructions they allow larger spans and/ or narrower timber cross sections, in renovations they help to safeguard the existing structure. Many trusses therefore do not need to be replaced or doubled up at considerable expense, even if they exhibit obvious cracking. In such cases, however, an expert report must always be obtained. 

BRUTUS threaded rods can be shortened to any desired length but should be pilot-drilled to 13 mm. Care must be taken to avoid drill wander when drilling the holes.

It is used for transverse-shear reinforcement:

• of building trusses 

• at notches and openings 

• at transverse connections

Things to bear in mind 

• Pilot-drill to Ø 13 mm 

• The drill bit can wander while drilling deeper holes

Reinforcement of Arched Glulam Beams

Gary Pavlicek  of EDR Limited used his thoughtful imagination and was able to compress separated arched laminated beams. Using a 30 Ton Jacks for an accumulative force of 360 TON, short cuts of steel beams, and a rods he was able to pull the laminate together and then with ASSY Plus VG 8 x 580 and 480's he was able to structurally bind the laminate together and restore.

 Joe Miller with Fire Tower Engineered Timber assisted with the engineering stating "To be honest, this didn't take that much effort, to make work. The engineering (and failure mechanism) was pretty obvious. Rather than use the original repair by the original engineer (which was structurally sufficient, and, would have worked), which would have required drilling a lot of holes, and, doing a lot of epoxy work and the rest, by using screws, we were able to save a lot of time, and, not have to weaken the cross-section by drilling in all of the holes for epoxied in place rods.

So, saved time, effort, money, and, didn't create any additional damage / harm.

ASSY Plus VG Fully Threaded Self Tapping Structural Wood Screw

The "plus" in the name of the screw shows that it is a screw with a drilling point.

The ASSY plus VG is a universal screw which can above all be used in the wood glue sector, the carpentry, the wood and modular construction. These screws are especially suitable for: coupled purlins, ledgers, notch and opening reinforcements, main/secondary support beam connection, build-up beams, rafter purlin connection, applications in structural panels/wood frame construction and compression perpendicular to grain and shear reinforcements.

Due to the full thread screw connections can be produced which can stand high bearing loads.

The screw is produced either with a cheese head or a countersunk milling pocket head. It can be hardened, galvanized and yellow or blue passivated.

 

A plastic slide coating reduces the screw-in torque, so that less power is needed for the handling.

Since drilling and screwing can be done in one work step you are capable with the ASSY plus VG to produce screw connections in a time and cost saving way which were up to now difficult to handle.

Self-tapping tip
Significantly reduces the tendency of wood splitting, eliminates pre-drilling requirements reduced edge distances are permissible.

Fully threaded
High withdrawal resistance. High load bearing capacity.

Hardened steel
High tensile strength.

Plastic slip-coated
Reduced screw-in torque.

Countersunk head with
milling pockets
The countersunk head ensures proper scew-head bearing in steel-to-wood connections.

Cylindrical head
Reduced tendency to split compared to countersunk head. The screw can be installed concealed/hidden in the wood by driving it into the wood.

System Solutions with ASSY Plus VG Fully Threaded Structural Wood Screws

System solutions

ZD-plates

Problem

A portal frame is defined as an assembled load-carrying system of posts and beams. When portal frames are not clamped but tilt mounted on the support leg, they are also able to transfer horizontal loads. Instead of a fixed support at the post base a rigid connection between pillars and beams is created. For this reason a rigid design of the frame corner is necessary. With the increasing relevance of engineered timber frame structures time and cost effective solutions for rigid timber connections between posts and beams are essential.

Current Solution

Currently rigid frame corners in timber structures can be achieved by:

• Post and beam connected by metal parts and nails/drift pins (high assembly effort on site)
• Post and beam connected by pre-glued single or double finger jointing at the shop (elaborate and bulky)
• Post and beam connected by steel parts, for tensile forces, and hardwood inserts for compressive forces.
• Post and beam connected by doweled haunch

 

The disadvantage of these solutions is that they consume too much time, money and effort upon assembling.

SWG solution

The SWG solution is a combination of wood and steel parts. Its essence is a system solution around the ASSY Plus full thread screw, containing of the ASSY Plus VG and tension-compression plates (ZD-plates). In addition to that conventional steel plates and steel bolts (M16) are used.

Technical benefits of the SWG system

• Combining wood and steel construction
• Simple pre-manufacturing
• high level of pre-manufacturing possible
• easy to assemble
• reduced on site construction time
• Optimized connection capacity through combination of tension and compression screws
• reverse loads are taken with ZD-Plate - tension and compression screws

 

The ability to transfer tension and compression forces is unique to the ZD-Plate system.

Commercial benefits of the SWG system

• value added for timber construction companies
• standard timber cross sections can be used
• Reduced number of fasteners when compared to common connection systems
• Time and cost reduction for assembly
