Decki ng Solutions suitable for domesticfioor loading

Reduced Groundwork

Beamlock cuts groundwork by up to 50% as support posts can be as much as 4m apart No need to worry about the structural support

posts being at right angles,vertically or in line as the Beamlock System automatically creates a right angle along w~h any vertical adjustment.

Making the best of a sloping site I Engineers - Consultation - B Regs

No need for structural engineers I consultation fees when you are challenging a sloping s~e, as Beamlock has full building regulation approval

on structural and fire performance up to 22m high,You have the choice of a continuous deck level due to 22m height possibility,as opposed

to deck level changes, therefore makng ~ more practical and usable,Where a post height IS less than 22m please ask for details,

Design

Due to the beam section size provided and the assembly process there is no need for an outside joist or frame joist.Also, on a sloping site,

the requirement for the diagonal brace (above Im post height) is not only a functional engineering element but also an architectural,

attractive, heritage feature. This all resutts in a very attractive front elevation.

The Beamlock Frame

No need to bo~ together the main support beams pnor to the decking sub base.The Beamlock frame is the main support frame and also

the decking sub-base, unlike other conventional applications.The Beamlock section 138mm x 16Smm avoids the need to bo~ two joists

together to carry an additional platform.

Longer Lasting - AvoidWet Timber

None of the joists or structural support posts will be in contact w~h the ground There is always a minimum of 50mm from the bottom of

the support post to the concrete foundation.

Layingthe Deck Boards

No need to consider where to place double joists as Beamlock 138mm horizontal plane provides plenty of surface area for when two deck

boards meet.

Keep Timbers Clean

Keep the timber post elements dean by having the advantage of

assembly after completion of all groundworks.

Conservatory Solutions

•

Beamlock has devised a simple solution for building conservatories. The modular Beamlock

System nts perfectly with a range of standard windows and patio doors, making most parts

of the conservatory available off the shelf. Beamlock posts and beams provide a solution

to nt every design.You can choose between full length windows or part wall and windows.

Braces can provide a decorative feature behind the windows. Cross beams enhance the

interior design of the conservatory or extension.

Please note: On illustrations0ande it is essential on conservatories that a structural wall

is fixed to the Beamlock timber frame (either end or sides) to a height of bOOmm above

DPe when you exceed more than one bay from the house elevation .

TREATED TIMBER

~EAMLOCK.

Timber1imber - full compliance to Hazard Class 3a. Surtable for external use, not in ground contact

All timber is supplied in accordance with the Pan European Forestry Scheme, the Beamlock System is produced using Pinus Sylvestrus

(10,800 - 13,000 bending per N/mm', comparison Oak 10,500 - 14,500 bending N/mm').

It is made up using lamellas of pine laminated togethe" thus providing incredible strength

(see "Stronger Than Oak Mortise and Tenon System").

I. Timber sections are dried in a climate-controlled kiln.

2. The lamellas are then laminated together to form a single solid beam using a high

frequency hot press.

3. The beams are planed to section to achieve a tolerance of +/- I mm.

4. The finished components are then treated to Hazard Class 3 uSingVacsol Aqua

double vacuum pressure impregnated preservative.

This manufacturing process ensures that all Beamlock timber components are of the

highest quality. avoiding all the typical problems such as shrinkage, splitting and variation

in size, nonnally associated with timber sections of these dimensions.

All extemal timbers must be coated with a proprietary brand of wood preserve" stain

or paint within 6 months of installation to avoid UV light degradation of the treatment.

Colour and Finish

The timber colour is unaffected by the Vacsol Aqua treatment process, which leaves

complete individual choice as to how the finished project can be decorated.

Preservative Treatment of Timber

All Beamlock timber has been treated with Vacsol Aqua double vacuum treatment, the most effective and environmentally sensitive

treatment on the market with an anticipated service life of 60 years in Hazard Class I and 2 applications. Cutting of the timber on site

is unavoidable. ThiS Will expose untreated timber and it is imperative that crosscut, notches and bored holes be liberally swabbed with

Vacsele End Grain Preservative.

Vacsol Aqua

Vacsol Aqua is approved to standards and speCifications of Building Regulations of England and Wales and Building Standards Scotland

and the NHBC for many different applications and complies with the following standards:

C I-I 0 BWPDA, BS5707 (1997), BS5589 (1989), BS5268 Part 5 (1989) BSI 186 (1986) BS5502,

BS6566 Part 7.

The design life is for 60 years in Hazard Class I and 2.

The design life is for 30 years in Hazard Class 3.

The Beamlock Pine System has had extensive structural testing

at the Building Research Establishment (BRE) Centre.

To establish a fair comparison to mortise and tenon oak

timber framing currently available from specialist companies,

we decided to do an identical test.

The results are shown in the graph. This is all achieved by uSing

the intelligent Beamlock connection system, a number of

sophisticated, modern methods - from laminating timber in

Finland to computer programming for cutting accurate timber

sizes.The final result is a remarkably strong and simple, yet

3.rchitecturally attractive system.

page 9

Building SystemThe Beamlock building achieves a traditional look, with the security and reduced

costs that only modern technical production methods can bring, leaving you to

enjoy the beauty of traditional construction in a natural material. Build times are

significantly reduced with a perfect result every time, the Beamlock parts just

connect uSing the pin provided. With just three major components, the Beamlock

System is an easily understood assembly process. The modular concept also

guarantees compact storage and transport solutions. Beamlock products are

compliant to the most recent wind code BS6399.

Beamlock Connection

This is the ultimate in timber connection. It is designed not only for high strength (as tested at the BRE.), but also for use in our

variable climate. Due to the fundamental connection relying on the stainless steel plates and tubes matching up. the moisture

changes in the wood do not cause any concern or inhibit the connection system from working efficiently and easily.The Beamlock

connection system is made with a combination of high tensile BZP,stainless steel (grade 304L) and aluminium components. The

Beamloek design is durable and can achieve a service life of a minimum of 60 years in internal dry environments and a minimum

of 30 years for external exposure.

Installation Advantages

Two people can easily build a Beamlock structure with minimal tools and skills. Simple assembly means that you will benefit from the

unique time saving design reducing build times and labour costs.

112 Hour Fire Approval

Beamlock System complies to BS 476-21 half hour fire exposure, which IS considered suitable for the support of upper floor loading.

This negates the requirement for fire calculations if half hour fire determination is required.

Weight and Construction Advantages

Beamlock is a safe site product providing strength at easily managed weights. Posts and

beams are supplied in easily transportable modular lengths to a maximum of Sm.There is

no need for a crane or multi lift as two people can handle all components. Typically. on a

4m span, the Beamlock components weigh just 48kg.

Kiln Drying Compact storage and transport solutions.

All timber spends approximately IS days in individual kilns drying out to IS% (+/- 3%) humidity.The timber contracts by about 10%

and reduces in weight by about 40%.This is a great benefit in indoor applications as the Beamlock components will not split or move

dramatically in the future when heat is applied.

Extendible

The system allows easy extension at any time from a Beamlock post, allowing your buildings to grow with your needs and budget

page 10

'4EAMLOCKO

Last Minute Changes

With such a flexible system you can decide on brace positions suitable for garage doors, patio doors or windows just before you putthe building togethec

Treatment & Finish

Factory pre-treatment ensures a hazard class 3 approval allowing the posts to be exposed to the elements. Note: Class 3 approval is

subject to further application of surface coatings. Beamlock components are supplied ready to decorate. They are planed to the highest

joinery standards and need no extra preparation before painting or staining.

Quality

Beamlock is proud to guarantee consistent high quality manufacturing. We provide joinery grade timber machined to +/_ I mm.

True 90' degree Angles

The Beamlock System automatically creates appropriate angles and upright. Due to the simplicity of the connection system, you cannot

get the angles wrong'

End Tension Plate

This attractive plate is also an essential technical component of the Beamlock System. Each unused face is finished off

with the end plate which reduces the longitudinal stresses in the timber

Adjustable Post Base Plate

The Beamlock System includes a comprehensive and unique post to ground fixing solution. There are two choices of fixing. (An

additional bOmm can be achieved from the same post length giving a maximum eaves height of 2220mm.)

I. New purpose built ground bearing over-site, (partially cover in concrete).

2. On an existing suitable surface, drill and fix.

This specially engineered base plate is deSigned to maximise full support up to 10 tons, (tension pulling strength 1.3 tons) and at the

same time positively fix the post to the ground below. An additional benefrt is the bOmm of height of the base plate for an over-site that

may not be level, an ideal solution, especially in garages and stables where frequent washing occurs.
