FOR

CUTTING SYSTEM FOR INSULATION AND CONSTRUCTION BOARDING

Field of the Invention

The present invention relates to the culling to size of construction boarding, particularly insulation types using a frame device and improved cutting method.

BackQround The use of surface board backed with rigid insulation or foil faced material for the added containment of a buildings heat is common and has been practised within the building industry for many years. It extends its usage from tradition plasterboard filled to the inside of walls, ceilings and generally unfinished surfaces inside domestic and commercial dwellings from the introduction in Kent in 1888. The board core is made of traditional natural materials coated to provide suitable application. It has been used to make good' existing or new interior surfaces and may be coated with a plaster or other finish. This type of boarding led the way for a thermal application to one of its side surfaces, due to the ever growing requirement to retain heat within buildings and help prevent the access of exterior cold air.

Insulation boards are fixed straight onto the surfaces including walls, using continuous ribbons of plaster or adhesive and other required fixtures. Extra fixings hold the boards firm, and joints between boards are sealed to prevent air leaking out. There are two ways to insulate a solid wall internally -with rigid insulation boards, or a stud wall. Stud wall insulation is thicker than rigid insulation boards, so it will reduce the size of your room more. But a stud wall is strong enough to hold heavy fillings such as kitchen units, radiators or wash basins. Insulation boards need fixings that go through them and into the wall behind.

If the plaster is uneven or plaster has been removed and the brickwork is uneven, the wall must be levelled with a layer of plaster or render before boards can be fitted, so a stud wall might be a better option.

The levelling of the wall surface is important to ensure the correct alignment of the board to the wall on installation.

I

Insulating walls internally will make the inside surface of the wall warmer, making it less likely that moisture in the air will condense on the wall. So if there are currently condensation problems then internal wall insulation could help reduce the problem.

It is difficult to insulate every square centimetre of a dwelling and there are almost bound to be some areas that remain cold -for example, where an internal wall meets an external wall. There is then a risk of condensation collecting in these areas and perhaps going unnoticed until a problem develops. This problem can generally be minimised by insulating carefully around window recesses, doors and the edges of internal walls.

If the insulation is incorrectly fitted, there is also a risk that moisture will migrate from the warm air in the room through the insulation until it meets the cold solid wall. It can then condense inside the wall structure and cause problems. This issue can be avoided by adding a vapour control layer on the inner surface of the insulation and ensuring that any breaks in this layer are carefully sealed.

And as with all wall insulation, it is important to make sure that any existing problems of rising damp or penetrating damp are fixed before insulating, otherwise there is a risk of the problem getting worse over time as the moisture gets trapped within the structure.

For these reasons it is recommend that additional internal wall surface insulation board is fitted and by an experienced professional who can ensure that any existing issues are resolved and no new ones are created.

These professionals would purchase the insulation board in average sizes of 2,400 x 1.200 mm and often are required to cut it to varying sizes during application.

This is normally provided by the use of a hand or similar saw after marking a line to which to guide the saw during cutting.

This however, can be very difficult owing to the friction created by the density of the insulation board materials and it also creates a large amount of dust and debris during this process of culling.

This invention aims to provide a solution to the problem of sizing and culling insulation board and other possible boards in a more convenient, improved and less unfastidious way.

Summary of the invention

According to the present invention there is provided a frame device into which a piece of construction board or insulation board is inserted or slid'. This frame device ads as a temporary alignment housing for the board to ensure it is cut to the correct length and that the cut is true or straight, it also offers the guide for a cutting blade therein and reduces dust and debris.

The preferred embodiment has a pair of horizontal battens of equal length and either exacting of varying depths, which are seated to the working surface or floor, this is aided by rubber feet underneath both battens at suitably located points to provide added purchase. The length of the battens and all accompanying horizontal and vertical lengths of the frame are measured and provided to enable sufficient opening for the average size of complete boarding before it is cut.

The two battens are of any desired composite material, including woods, alloys or lightweight metals, plastic and hardened related materials suitable for tools of this nature, being lightweight, none-corrosive but hard wearing by nature of their constructive elements. They are of an elongated rectangular solid form, as is common in known batten shapes when referred to in construction industries.

To each end of the two floor or surface mounted battens of the frame are vertical ends, of a varying form but being of a squared or rectangular nature as a favoured option.

These ends are attached as a fixed addition to the end of the battens and support identical lengths of battens above. These two battens above have parallel alignment to those of the bottom or floor or surface mounted, seated pair.

The upper battens are also horizontal and are hinged to one end, these hinges being located to the upper edge of one of the ends, either to the left or right. These hinges allow the upper two horizontal battens to be lifted as a swinging engagement of the two, allowing insertions of a cuffing tool and the boarding for example.

To the entire length and centre of all battens is a space. This is enabled by all battens being positioned on the ends with an equal continued length of distance between them, that is precise from its start to its end on both the upper two and lower two battens, forming a channel, opening or groove.

The groove or channel of the upper battens is exacting to that of the lower, with slight allowances for structural design of the overall working application. The battens then play host to a cutting tool. This tool is of a varying long blade that is able to seat in length from the upper battens to the upper inside surface of the lower battens, this is to enable it to be pulled along, using the groove or channel offered between all battens as a straight guide. The cutting tool may require expansion pieces or blocks to make up the exact width between its blade and the interior edge of the groove between the battens themselves. The board requiring cutting, is slid onto the sufficiently provided opening between the two sets of battens, in their opening, this may be assisted by lifting the top two battens, which are affixed at one end and hinged at the other.

Once the board has been marked at the desired length and the upper battens have been closed and seated, the user may begin the cutting process.

The board may require a small amount of packing' to the end opposite to that inserted therein as the batten thickness onto which it is seated or laid would possibly provide a small gap or space from the floor or surface for the remainder of the board sheet.

This can be provided by a third party piece of suitable block or level material or as an inclusion with this product These spacers or packers would possibly be of variable sizes but design indicates that this underside would not be affected by the differing thickness of boards, as it is located underneath all of them.

To the pair of upper battens are screw threaded holding points, these have handle or tab areas, similar to the known wing nut' method and have a threaded spike or flat footed or rounded tip length that passes vertically though at least 4 holes in the surface of the battens to the top.

As the board is inserted, depending on the depth or thickness of the board, there may be a space between the board and the battens. To remedy this the 4 or more screw threaded lengths may be screwed in a downward motion, normally clockwise, until they contact with the boards surface and therefore hold it in place. The amount they are each screwed down will depend on the thickness or depth of the board inserted therein.

The user would either place the whole frame onto a suitably heightened surface or table, bench, surface or on the floor and position themselves opposite the cutting tool, as ft pulling the blade toward themselves during the process. Sufficient length is provided in each of these holding lengths to enable them to hold and adjust to the depths of all known varying boards.

A handle with gripping surface is held in the hand of the user and the cutting tool and its blade are pulled toward them, held in alignment by the guide blocks, to its upper and lower blade, seated within the space between all battens, as it moves along the groove or channel provided by the space between these.

As its true line passes through the board, the sharp cutting tool blade is able to cut though the awaiting insulation or other board with either a single stroke or repeated intermittent pulling of the blade through the board and its insulation composite. This cutting action may take several attempts or repeated pulling and cutting actions, dependent upon the density of the board being cut, which may vary from subject to subject.

As the cutting blade passes through the board the debris and dust is reduced in this disclosure due to the way in which the blade is able to approach and pass through the material is a more controlled aligned and exacting way.

Following the completion of the culling process taking the culling tool from one side of the frame device to the other, passing through the entire board width, if required, the upper two adjoined battens, can be lifted and the board and/or blade removed for maintenance.
