Lintel Durability - you do the maths

There are several British Standards relevant to lintel specification but none gives a difinitive guide to calculating lintel service life. - Dec 09.

Only post-galvanising guarantees compliance with British Standards governing lintels and their durability

It is the task of the structural engineer to validate the structural performance of a lintel, including the durability features that determine lifespan. But too few recognise that only post-galvanising will guarantee modern lifespan requirements in compliance with key standards BS EN845-2:2003 and BS 7543:2003. - Dec 09.

Streetwise recycling with Ecochute

17 July 2008

Sleek design and large underground capacity from Jones of Oswestry’s new on-street recycling chutes will suit LA ‘Recycle on the Go’ initiatives.

Jones of Oswestry’s Ecochute on-street recycling system provides segregated collection of recyclable litter – typically glass, plastic, card and cans/metal – with integral, large capacity underground storage using conventional wheelie bins.

Providing a low-maintenance, space-saving and aesthetic solution to on-street litter recycling, Ecochute units comprise a recessed, lockable access cover with integrated bin, hinged to a full flange frame for rigid fixing within paving construction. The cover incorporates spring-assisted lifting by one person to give access to a fully enclosed, wheelie bin housing below.

Large below-ground capacity

The large, below-ground capacity reduces the frequency of collections as well as minimising the potential for unsightly litter overflow and associated health risks from attracting vermin. The modular concept provides the flexibility to specify any combination of dedicated ‘chutes’ for collection of different types of recyclable waste, in contemporary stainless steel or more traditional designs, to blend with street furniture themes. Chutes can also be themed to carry advertising, retail branding, or simply local interest themes.

Variable capacities

The standard Ecochute unit is designed for 240 litres capacity wheelie bins conforming to EN840 (variations available for 120L and 360L bins), eliminating the need to buy additional proprietary receptacles and handling equipment. Typical installations offer the choice of one, two or four recycling chutes enabling separation of discarded items.

Mechanical winch for lifting bins

In contrast to hydraulically operated lifting systems requiring a power supply, Ecochute uses a mechanical winch which requires no services, is easy to install, less complicated to operate and virtually maintenance-free. The winch allows fully loaded wheelie bins (and loads up to 2 tonnes) to be safely lifted in line with manual handling requirements.

Segregated signage

Ecochute offers flexibility for a range of engraved or applied signage and emblems, including logos to indicate recycling function and colour-coded apertures in different shapes – such as green holes for cans and brown slots for paper – to encourage disposal of materials in the correct unit. Colour coordinated liner bags can be purchased as an alternative method of materials collection. 

Ecochute units can be manufactured for vehicle wheel loads of up to 25 tonnes (class C250), and heavier vehicle loads can be accommodated.

SoloBloc cover system meeting manual handling requirements

The Ecochute cover element is based on Jones of Oswestry’s popular Solobloc recessed access cover, which provides hinged, spring-assisted opening to enable operation by a single operative within lifting effort criteria of manual handling regulations. The recessed design allows paviours and other materials to be carried across the installation to minimise its visible footprint and allow design continuity.

High specification Duragalv finish

In line with the quality of Jones of Oswestry’s other structural steel products – access covers, tree surrounds, drainage gratings, disability access ramps and lintels – Ecochute is manufactured to a high specification of steel plate and post-galvanised coating for long term, reliable service life with a stated longevity.

Jones of Oswestry’s Duragalv post-galvanising, when applied to the company’s high specification steel products, provides a minimum 25 years service life typically sought from in-ground landscaping metalwork for public realm landscaping projects.

Follows state of the art European systems

Ecochute meets the demand for sensitively designed disposal points for on-street materials recycling, a trend that is already widely seen on the continent and is set to grow in the UK under the government’s Recycle on the Go initiative.

On-street recycling following Local Authority guidance for domestic waste

Aimed at promoting on-street recycling, Recycle on the Go was created by DEFRA (Department for Environment, Food and Rural Affairs) with the help of environmental charity Encams. 

Although not a legislative requirement, the government is hoping that voluntary take-up of the scheme by LAs will be encouraged by growing support among the UK population for public facing LEQ (Local Environmental Quality) initiatives.

Authorities can also make savings and generate income from on-street recycling by qualifying for recycling tax credits and through sale of materials.

Reduces operating costs

The main costs associated with on-street recycling are typically collection, MRF (materials recycling facilities) charges for sorting, and bin maintenance. Jones of Oswestry’s Ecochute is designed to reduce the onus of all three of these costs.

Firstly, the use of wheelie bins with generous capacity reduces the frequency of collection, and means that waste can be directly and quickly removed from the Ecochute, aided by the mechanical hoist, with minimum fuss.

Secondly, materials are already segregated into the robust, transportable structure of the wheelie bin.

And thirdly, the integrated chute and recessed cover are hinged into a rigidly anchored frame, providing a highly resilient, anti-vandal structure while affording lockable protection of the storage chamber below.

With one of the lowest recycling rates in Europe, the UK needs to reduce the amount of waste going to landfill by nearly two thirds by 2020 to meet EU targets.
