Huck ® Fasteners and Modular Construction
Around 50 % of UK steel construction work incorporates portal frames . Thanks to the durability , adaptability , cost-effectiveness and low maintenance that steel frame building offer , they are an excellent choice as they are so adaptable for both commercial and domestic requirements .
The building industry together with construction methods have seen a technological revolution in recent years driven by the need to make construction faster , cheaper and safer . With the use of clever technology such as Building Information Modelling ( BIM ), drones and artificial intelligence ( AI ) architects and contractors have increasingly detailed information at their fingertips .
Images and precise measurements of a site taken by drones can be used to create detailed graphics and full-colour digital models / 3D site maps . AI algorithms are able to analyse data from a wide range of sources , including building plans , weather patterns , and traffic data , to make predictions about how a building will perform in the ‘ real ’ world . This has enabled architects to design buildings that are more energy-efficient , resilient , and sustainable as well as manage information on construction projects throughout their life cycle , right through to disposal .
The creation of geometric models as part of this process has allowed buildings to be conceived collaboratively and tested virtually before they are built . These detailed virtual models make it possible to live and breathe the construction and operation of a building before the production has even started .
Modern volumetric modular off-site construction continues to develop at a fast pace ; consisting of two distinct industry segments , re-locatable modular and permanent modular - both are built off-site in controlled environments to high standards . Often manufactured as a series of structural units , stacking and / or adjoining factoryfinished modules - these then make up the finished combined structure of a building once assembled on-site .
Re-locatable modular - temporary modular buildings are ideal for situations that demand quick construction , they must also be durable enough for future relocation and repurposing . Examples include , temporary classrooms , Sanitary and WC cabins , communication pods , show rooms , job / site trailers and glamping pods .
Permanent modular Construction ( PMC ) - are designed to remain in one location for an extended period of time . Examples include , schools / student accommodation , healthcare facilities , hotels , and restaurants .
Enhanced on-site productivity during the assembly phase ensures that the cost savings of modular builds can increase with production scale . Factory assembly based on ‘ template ’ builds means that approved designs can be reused and mass produced quickly and easily . These savings can grow rapidly , making it easy to achieve much faster output with less waste , downtime due to environmental effects , reduced labour and energy costs – all significantly lowering production / installation costs per unit .
Sustainability and identifying technology solutions that benefit the environment and manufacturing processes has become increasingly important to both consumers and businesses . With all of the new technological advances it makes sense for manufacturers to review their construction materials ; fastening solutions are sometimes overlooked in this process ; Huck ® fasteners offer a wide range of permanent joining solutions that will both maximize factory efficiencies and offer maintenance-free , vibration-resistant joints for the full servicelife of the structure .
Because Huck ® fasteners offer relatively high tensile , shear and clamp properties they are suited to applications where the joints are integral to the structure . Offering a clean and safe alternative to welding and a more efficient fastening method than standard nuts and bolts , Huck ® fasteners offer benefits which other fastening methods cannot , including quick and easy installation , elimination of re-checking / replacement , and ultimately cost reductions .
HUCK ® LOCKBOLTS AND STRUCTURAL BLIND FASTENERS
Huck LockBolts ® and structural blind fasteners are designed to provide durable , vibration-resistant fastening solutions , additional benefits include : -
Performance and quality - Quality fasteners engineered to deliver optimal and consistent joint performance . Modular buildings need to withstand the vibration of rumbling down the roads on the back of a truck whilst being delivered to site , and then whatever the elements throw at them , from wind loads to corrosive substances in the air .
Lifetime costs – Construction projects built today need to be built to withstand the tests of time for years to come . Huck ® high performance joints can deliver considerable cost savings over product lifetime .
As new construction methods emerge the range of fasteners must keep pace .
Hucks ® DIBt approved range of grade 10.9 LockBolts offer maintenance-free vibrationresistant joints for the full-service life of the joint . Other benefits include fast and easy installation , and an installed dynamic performance providing up to five times greater fatigue life than conventional HV * bolts . (* The ‘ HV ’ mark comes from the German term ‘ Hochfest Vorgespannt ’. This refers to a HV preloaded bolt , applied in a bolt / nut / washer assembly according to the EN 14399 / 4-6 standard . These bolt connections are used in preloaded steel constructions ).
