Description

[0001] The present invention relates to a block for supporting a hoarding system. In addition, the invention relates to a hoarding system for providing a temporary board fence erected around a building site.

[0002] In particular, this invention relates to a hoarding system which provides greater Climate Positive and Circular Economy benefits than traditional plywood hoarding which is generally scrapped after use under the standard current working procedures. The system of the invention comprises steel, concrete and recyclable uPVC. It can be reused multiple times to provide hoarding around multiple building sites.

Background of the Invention

[0003] To comply with Health & Safety regulations construction sites generally require the erection of perimeter hoarding around the site to act as a barrier between the construction zone and public areas. In addition, the hoarding provides a solid barrier to help prevent theft of plant and materials from the construction site.

[0004] A medium sized hoarding could have a perimeter of 300 linear metres in which if constructed using traditional timber and plywood hoarding would require an estimated number of nine 30 - 50-year-old trees cut down for its installation.

[0005] The most commonly used system in the UK is in-ground hoarding, this requires holes to be dug in the ground which then have timber posts inserted that are backfilled with wet concrete. After allowing the concrete to cure, timber horizontal rails are nailed/screwed across the posts and plywood panels are nailed/screwed to the rails. The plywood panels may carry visual information/branding via graphics and/or be painted in the client's corporate colour(s).

[0006] As an alternative to the in-ground timber system described above, the same type of system or a combination of steel and plywood hoarding systems are also known, where the posts are fixed to a concrete block which is the kentledge to hold the hoarding system in place rather than digging and concrete posts into the ground, these are known as no-dig systems.

[0007] At the end of a project the known hoarding is generally taken down with the materials being sent to be downcycled or to landfill.

[0008] In light of the problems discussed above, various proposals have been made, but there remains a need for an improved system which address one or more of the problems presented by prior art arrangements. In this regard, the present invention seeks to provide an alternative system which preferably addresses one or more of the problems presented by prior art arrangements. In particular, there is a need to provide a sustainable closed loop hoarding system which does not require any timber or plywood in its construction, and that can be repeatedly reused.

[0228] Each post (50) has been designed in such a way that it can be connected to more than one block (1) if they are required to be stacked on top of another as shown in Figure 3.

[0229] Each post (50) has a plurality of holes (53) defined therein so that the posts (50) can be extended to provide a solid hoarding over the standard 2.44m high or for mesh panels to be added for increased security but without associated increased wind loading.

[0230] At the top of each post (50) there is provision for a connection for a lighting bracket to be provided.

[0231] On the rear of each post (50) there is provision for a number of cable support brackets to be provided.

[0232] The welded U shaped rail supports (60) at the front of each post (50) have been set-out to take into account uneven ground levels, additional brackets (60) ensure the horizontal rails (70) can be installed level.

[0233] The U shaped rail supports (60) each have a hole (62) defined therein at the front to allow for fixing steel mesh panels in lieu of solid hoarding; in this case horizontal steel rails (70) are not required.

[0234] Steel rails (70) can be supported by the rail supports (60) and provide the connection point between the steel posts (50) and the uPVC hoarding panels. They are fabricated using 40mm x 40mm galvanised boxed steel and simply slot into the welded U shaped rail supports (60) on the steel posts (50) without any mechanical fixing and can be removed by lifting upwards out of the U shaped rail supports (60).

[0235] Each steel rail (70) has holes (71) defined therein at each end to allow for fixing to pedestrian gate frames where required.

[0236] Three rails (70) are used as standard with each post (50) however if required four rails (70) can be installed.

[0237] At ends and corners of the hoarding each rail (70) can be slid backwards inside the U brackets (60) so not to protrude the hoarding line.

[0238] Shorter steel rails (70) are provided where elevations are under 3m.

[0239] Clips of electroplated metal are included to connect the recyclable uPVC panels to the horizontal galvanised steel rails (70) every 0.5m.

[0240] Each clip has four arms with flat plates that pull against the ribbed sections on the uPVC panels when the bolt is tightened against the back of the horizontal steel rail.

[0241] The uPVC panels are typically 2400mm long x 500mm wide x 35mm deep at three points and 10mm between the structural ribs of each panel.

[0242] White panels are extruded from a mixture of post-production and post-consumer waste uPVC, coloured panels are made from virgin uPVC - both recycled and virgin can be recycled numerous times at the end of the life.

[0243] The panels are extruded with one male edge and one female allowing them to be joined together and connected to together and to the horizontal steel rail (70).

[0244] The front face of the panels is flat so when joined together the system provides a seamlessly flat face that vinyl graphics can be applied to directly without any interruption of vertical joints that is known in other plywood hoarding systems.

[0245] Being made from uPVC the panels offer far greater life expectancy than plywood hoarding. A life of 10 years is expected when compared to 2-3 years for even a higher quality standard class 2 plywood that is traditionally used for external plywood hoarding systems.

[0246] Panels can be extruded in lengths of up to about 7m in length in one piece meaning fewer joints are required.

[0247] Panels can be extruded in any RAL colour to meet corporate branding requirements.

[0248] Advantageously, a standard 2400mm x 500mm panel weighs 5.7kg compared to 25kg for a typical 18mm 2440mm x 1220mm plywood panel. This facilitates installation as well as transportation.

[0249] In addition, advantageously, panels can be processed back into pellets ready to be reused for extruding back into new panels.

[0250] Optional horizontal top and bottom releasable uPVC trims can be added to the hoarding system by inserting the panels into the trim. These trims provide the advantage of hiding any differences in ground levels as well as providing an attractive finish to the top and bottom of the hoarding.

[0251] Rigid and flexi vertical corner trims can be added into the hoarding where required to provide an attractive finish.

[0252] All trims can be reused multiple times and are recyclable.

[0253] The hoarding system in accordance with the invention removes the need to use timber or plywood in its construction. These valuable resources are a poor use of material for construction site hoarding that are generally installed for 1-5 years. For comparison, it could of took 30-50 years to grow the trees required.

[0254] The invention eliminates the potential danger of digging holes into the ground and avoids the need for wet concrete which delays the installation of hoarding often resulting in the requirement for return visits.

[0255] The hoarding system of the invention is LCA verified as 'Net Zero Carbon' and offers Climate Positive benefits such as tree planting and carbon offsetting against every metre installed.

[0256] The hoarding system of the invention provides the advantage that no painting on, or off site is required which eliminates any COSHH risks (Control of Substances Hazardous to Health) and unlike plywood hoarding it requires no ongoing costly maintenance.

[0257] When the hoarding system of the invention is no longer required it can be easily dismantled and transported by vehicle to a different project or returned to be stored for future use without any materials going to landfill.

[0258] The hoarding system of the invention provides the advantage that improved manual handling is gained as a standard 2400mm x 500mm panel of the invention weighs 5.7kg compared to 25kg for a typical 2440mm x 1220mm 18mm plywood panel.

[0259] The above described embodiments have been given by way of example only, and the skilled reader will naturally appreciate that many variations could be made thereto without departing from the scope of the invention.
