Abstract

Paving templates to assist with the initial setting out of brickwork or paving slabs in a bonding pattern. There are a number of different shaped templates to fit bricks or paving slabs of different shapes and sizes, including quadrilaterals and other regular polygons. Template pieces can be attached to one another using screws or other fasteners such as a bracket. The templates have indents to accommodate paving block lugs. There are holes in the templates to allow builders string lines to be attached to mark out straight and parallel lines as needed. Some template pieces feature a centre hole which can be used as a pivot point to mark out a circular shaped paving area.

Description

Description

The invention relates to a paving system that uses one or more paving templates to produce a block paving or paving slab area by having the bricklaying bonding built into the paving templates.

To cover all designs using two paving templates are preferable and when using two paving templates the templates are connected by way of standard inter screws or fasteners to create one large paving template for marking out and the laying of block paving and paving slabs Different paving templates and attachments can be used for the laying of half bond quarter bond and stack bond designs and cover the laying of all regular quadrilaterals and regular polygons shaped or sized paving blocks or paving slabs using the paving system’ page 1/18 Fig 1 shows sets of two paving templates to lay 200 xlOO mm paving blocks, Fig 2 shows 200 x 200mm paving templates for laying of stack bond, Fig 3 shows template for laying hexagon paving slabs. Fig 4, shows 160 x 160mm paving template for laying 320 xl60 mm 240 xl60mm paving blocks and slabs in any bricklaying bond.

The background is very limited in this field as paving machines do exist but they are machine driven by engines and used on an industrial scale, a hand tool I have found is an earlier application by myself PCT/GB1996000413.

The limitations of PCT/GB1996000413 were despite it being a block paving tool for someone to use who had little or no knowledge of the Bricklaying trade the set up was to use four templates along with colour coded lines and with adjustable legs built in spirit level was to much for a lay person to understand with some knowledge of bricklaying still required, the biggest drawback was paving block lugs as shown in page 6/18 where paving lugs are cut into the template whilst with PCT/GB 1996000413 this was not taken into consideration and a person would need trained in bricklaying to take that into account as bonding would not remain true and required the use of 4 larger paving templates PCT/ GB1996000413 was not versatile enough.

The advantages of this paving system are that it is designed for the DIY individual and only one or two templates are needed with no string lines needed all templates having lug spaces built in to every step of the paving template to accommodate all size of lugs on paving blocks and legs are a fixed height meaning that the paving templates are ready to use without any bricklaying knowledge required and only one or two templates required with no string line required for laying paving and when two templates are used they are connected with inter screws or fasteners to create one large template.

The manufacturing of paving blocks and paving slabs is changing all the time and the choice is vast and the present invention takes this into consideration by using the same technique throughout a paving template or attachment to a paving template can be added no matter what the shape and size as the paving system can be used to lay all regular quadrilaterals and regular polygons designs of paving blocks and slabs or all paving blocks and paving slabs available now and future paving blocks and paving slabs manufacturers may create as long as they are regular quadrilaterals and regular polygons designs.

Other advantages are with global warming and climate change high on the agenda and a real concern block paving and paving in general has to be looked at and local authorities are now addressing this as well as paving Block manufacturers and the paving system described hope to address some of these issues’ for example showing how to pave tyre tracks in attractive designs rather than block pave a whole drive which uses more materials and less paving in areas of the country where flooding is regular, when employing a builder to lay a block paved drive a skip has to be hired and other tools so to get the use and money worth the householder tends to get the whole drive done as the are paying the cost of land fill and skip cost anyway.

Paving block and slab manufacturers have created an vast amount of choices for the consumer and a design that has a lawn or flower bed in it can be more aesthetic looking.

Using a this paving system the inventor believes that smaller scale jobs will be attempted and quality rather than quantity will be the order of the day by using the paving tool tyre tracks one metre wide can be easily achieved meaning less material excavated and remove by skip to a landfill or remove the need of landfill altogether by using the soil excavated to create raise flower beds or patios using the paving system to mark out the areas

If a DIY user can create these any paving design themselves and be able to mark out paving lawns vegetable patches and flower areas may well become more desirable than just paving the whole area and more cost effective which will also help to conserve water by allow the rain water to drain off into the ground and prevent flooding.

Paving block manufacturers have tried to address this by make the lugs on paving blocks larger creating larger spaces between paving blocks for water to drain although this help and there are calls for even larger lugs this is not a solution as the sand in larger spaces will just be washed away or allow weeds to grow making the job look unsightly, so the solution of more precise paving whilst paving less overall seems the best option

The paving system described is aimed at saving the user money which is always desirable and will help to reduce the amount paving overall as paving is known as a major cause of flooding and is a problem within the UK and other parts of the world.

The Invention will now be described by way of reference of accompanying drawings.

The paving system works by using one or two paving templates and if a different size of templates are required to lay different shape of size of paving block or paving slab in half bond or stack bond attachments for the appropriate size can be connected to any paving template by way of inter screws drawings 1/18 show four sets of templates used in these drawing 1/18 Figl shows two paving templates for laying of standard block paving 200 x 100mm for half bond 1/18 Fig 2 shows two templates for laying of 200 x 200mm or stack bond also known as running bond. 1/18 Fig 3 shows two templates for laying hexagon paving slabs 1/18 Fig 4 show 160 X 160mm paving templates that does both stacking bond and half bond as sizes of paving blocks and slabs for this size are 160 x 160mm 240 x 160mm and 320 xl60mm and any template shown 1/18 Figs 1-4 can be changed to lay any other size of paving block or slab by adding template attachments, sizes of templates can be used by way of attachments to any paving template as shown in 1/18 Fig 1-4 12/18 Fig 1 Fig la and Figlb show a 200 xlOOmm attachment to a 200 x 200mm template Fig 2 12/18 shows a 160 x 160mm attachment and 200 x 200mm paving template Fig 2a 200 x 200mm paving template with 160 x 160mm paving attachment fixed with standard inters screws.

The paving template design is the same whichever paving block or paving slab size is used a 200 x 100 mm paving block will have a 100 mm step with built in indents for block paving lugs as shown in 2/18 Fig 1 as paving blocks are laid in half bond design the half bond is built into the paving templates as shown 2/18 Fig la and Fig lb and when the paving template is placed together the half bonding is complete for the continuation of half or quarter bond as the paving templates give the impression of paving already marked out or the job started which is the skill involved in bricklaying and paving.

Fig 1 3/18 shows a paving template and Fig la 3/18 shows how the template is designed, 3/18 Fig 1 b shows one way the templates can be attached to do a stretcher half bond design horizontal or vertical with the templates mimicking the setting out already done and 3/18 Fig Ic shows another way of connecting the templates mimicking the setting out for half or quarter stretcher bond or herring bone half bond design as the templates replace the skill needed for this action or starting block paving by setting out the first paving course.

When a rectangle paving block or paving slab is to be laid for instance if the measurements were 300 x 150mm then the steps in the paving template for that size would be would be 150mm and if the size of paving block was 250 x 125 mm the step would be 125mm and so on with indent for paving lugs built in where appropriate.

When laying square slabs or paving blocks such as 160x160mm then the step would be 160mm and this can be used to lay 320 x 160mm in half or quarter bond stretcher or herring bone design the same as the 200 x 100mm template as well as lay square 160 x 160mm square paving stones or paving blocks the same technique creating a paving template for square paving is the exact same as for rectangular paving as shown in 4/18 F 2 has a 200 x 200mm paving step Fig 2a shows how the template is designed where 4/15 Fig 2b Fig 2c Fig 2d show the various way the templates can be connected, the setting out of the paving slabs has already being done by the templates replacing the skill needed and all paving templates for laying paving blocks and paving slabs of regular quadrilaterals sizes and shapes are created this way.

Regular polygon designed templates are created exactly the same as regular quadrilateral designed templates page 9/18 shows Fig 3 shows hexagon paving template Fig 3a shows a fixing plate Fig 3b shows an Inter screw Fig 3 C shows where to connect the fixing plate as does Fig 3d.

Shown in 10/18 where a hexagon paving slab is to be laid Fig 3 show a hexagon paving template Fig 3a Fig 3b Fig 3c show the different ways the hexagon templates can used for different effects designs of paving again keeping the half bond in Fig 3 b and when the paving slabs are laid round the paving templates they are removed as shown in Fig3b when the templates are removed two hexagon paving slabs can be placed in the space either the same colour or different to create a design or left empty for shrubs.

Fig 3c 10/18 shows true kept and how when you complete the laying round the template you just move the template and position to continue to the desired size of paving area, in Fig 3a shows stack bond is kept true.

As there is no or little background history to go on for a product that replaces the skill taught to bricklayers by using the paving system of templates such as on page 14/18 shows Fig 1 show a selection of shapes and one chosen random which is a pentagon shape and at this time it is not known if there is such a shape of paving block or slab and if not then there maybe one in the future so for the purpose of explaining the paving system a paving template for a pentagon shape using the same procedure and technique as for the regular quadrilaterals paving templates and polygons is created and shown using the paving system.

An example will be shown how to create a paving template using the system described, 14/18 Fig 2 shows the shape chosen 14/18 Fig 3 shows how only half the shape is used 14/18 Fig 4 shows how we take the outline of the half bond and mirror the outline 14/18 Fig 5 it is decided at this stage the shape of the whole template and where holes are to be positioned so the templates will connect till we have something such as 14/18 Fig 6 we then mirror a copy of it and we have our two template shape designed for laying pentagon shaped paving slabs or paving blocks and then we connect the templates and start paving knowing the bonding will be kept true which in this case because of the shape of paving slab will be stacking bond in a circular pattern.

As shown in 15/18 Fig 1 the connected template is moved round and placed into position then lay you paving in the spaces and keep moving it round till the pattern is completed which is a circle, this example shown may suit better as an attachment rather than a main base template which can connect to any template in 1/18.

As long as the paving blocks or paving slabs are regular quadrilaterals or regular polygon then any paving template or attachment for paving template can be created using the same procedure for paving blocks that exist now or any that paving manufacturer’s create in the future.

The way the paving template connect are different between regular quadrilaterals and regular polygon paving templates where the quadrilaterals templates such as the 200 X 100 mm shown in pages 7/18 Figl Figla and 8/18 Fig 1 shows the 200x 200mm Fig la 8/18 and Fig lb 8/18 shows 16 xl60 mm paving template have shade ends, these shaded ends are equal to one and a half paving blocks in the 200x100mm paving template Figl and one 200 x 200mm square in Fig la and one 1600 X 160mm square in Fig lb.

If the template thickness is 20mm then these shaded areas will be 10 mm so when the are joined in the centre the two ends that are joined in the centre by inter screws will be 20mm the same thickness as the rest of the template as shown 8/18 Fig Id.

The reason for this is to give strength to the overall template by creating a solid single template when joined but leaving the option for the user to add more templates and with the rise in home 3d printing and limits on size at present than industrial 3 d printers using this design a single template could be made in two or more parts and connected with inter screws or fasteners.

Regular polygon shaped templates have a different way of connecting together as shown in 9/18 Fig 3a by way of a fixing bracket using inter screws or fasteners Fig 3b this bracket is just a normal bracket made of plastic or metal which there are many to choose from in the market place, in positioned holes in the paving templates as shown in 9/18 Fig 3c and Fig 3d depending on which way the paving templates are to be used for the paving job to be done as all attachments will connect by matching up the holes in the attachment with the templates and attached to paving templates holes with inter screws or fasteners.

The holes on the templates are positioned for connecting the templates to other templates as shown in 5/18 Fig 2a Fig 2 b Fig 2c for the 200 x 200mm paving template and for attachments such as 12/18 Fig 2 . 13/18 Fig 2a shows a centre hole and a inter screw connected Fig 2b when used, this centre hole is for doing circular work whether paving or marking out a circular area attaching a builders line to the inter screw and move round in a circular motion as in 13/18 Fig 2c to marking out a circle.

Page 11/18 Fig 3 Fig 4 shows how any paving templates can be used to mark out an area such as rectangular by using builders string lines and attaching to holes provided where any straight line or parallel lines at any angle are needed marked out in a garden such as straight line for posts for a fence or grass or flowerbed.

Paving lugs come in various sizes 3mm 4mm 2 mm depending on manufacturer of paving block and to allow water drainage have increased in size over the years 6/18 shows how the paving lugs are built into each paving template and Figl and Fig 2 are shown with indents built in which are 10mm x 10mm to cover all lugs of all sizes now and if increased in size in the future so the paving blocks will sit flush in the step and keep the bonding true.

As shown in page 1/18 Figs 1-4 the paving system is made up of four sets of two paving templates that use the most popular sizes of paving blocks and paving with other sizes used on any paving template 12/18 Fig 2 by way of a paving template attachment.

Pages 14/18 shows how to create any paving template or attachment for the laying of bricklaying bond designs covering the laying of all regular quadrilaterals and regular polygons shaped or sized paving blocks or paving slabs to be used with the paving system template sets.

The height of the paving templates and attachments will be lower than the height of paving blocks or paving slabs to be laid with no set height and can be anything from a few millimetres to 20 mm below the height of the paving block or paving slab and the legs will be fixed as part of the moulded templates.

Any string lings used can just be normal builders lines and any inter screws used can just be standard inter screws.

As shown in 17/18 Fig 2 shows how the design is the same as 17/18 Fig 1 different sizes can be used in one template which makes the system versatile and 18/18 Figl and Fig 2shows a scaled down version that could of 6 templates one metre in length with a width under 200mm which paving block suppliers may supply for hire with packs of set amount of paving blocks with sand base material to do certain patterns

Drawings 1-18 show using the paving system of pre set bonding in paving templates covering the laying of all regular quadrilaterals and regular polygons shaped or sized paving blocks or paving slabs the templates can be any size or a mixture such as shown in 17/18 Fig 4 and 18/18 Fig 1 or 1/18 Figs 1-4 which featured in most drawing examples.

All templates can have two different sizes of bonding on one template, for instance a 200 X 100 template can have 160mm steps on the opposite side from the 100mm step side not shown in drawings, although using a straight edge on one side of each template is shown in all drawings and if another size is required an attachment can simply be added.
