Abstract

A plastering profile compiises a ceiling brace, a two part main body and a floor brace, having a winding mechanism to wind the jig to a required height at which it is braced in position between the floor and ceiling. A pair to profiles can be used to plaster an internal angle. The profiles are placed at right angles to each other at a corner to be plastered and braced in position. An internal angle edge tool is then dragged up the profiles to smooth plaster in the internal angle. One of the profiles can then be removed an repositioned parallel to and space from the other profile to allow continued plastering of a flat wall leading from the internal angle using a straight edge tool. The profiles may include a plumb line attachment, built in spirit level an spirit level cradle. An additional extension piece may be provided for use between the floor brace and the main body.

Description

I

Plastering Profile This invention relates to a device for plastering walls, internal corners When plastering a wail or internal angles the result is often out of square and un-level or plumb.

With the use of conventional tools the out come of plastering is seldom precise and if is prease this may be lime consuming both for plaster and contractor. However to over come these problems the present invention proposes of the use of tw or more profiles used in series to produce a time effective,plumb, level and straight plastered profile. In series also to produce time effective plumb, level and straight profiled internal angles.

The use of A plumb Tine attachment means easier erecting of the profiles to ensure good alignment The use of two spirit levels, one being built in and the other in a movable cradle will also ensure the profile being level and true..

The use of a rubber sbip on ceiling bar ensures that the profile can be easily moved whilst being in the erect position.

The use of a string Line to enswe profiles are true in series.

The use of an extensions to change the basic height of the profile for higher ceilings.

The invention will now be described solely byway of example with the references to the accompanying drawings in which: Figure 1 shows a profile when connected together and erected.

Figure 2 shows the ceiling brace with pie drilled holes for the self tapping screws to be fitted and the shroud.

Figure 3 shows the top half of the main body with winding mechanism plate Figure 4 shows bottom half of profile showing provision for removable spirit level cradle Figure 5 shows floor brace with removable blocks and adjustable feet Figure 6 shows an extension piece to fit between floor brace and bottom of main body of profile..

Figure 7 shows internal angle tool.

In figure 1, a plaster profile unit I includes an internal angle tool. This is made of a flat plate section and angle bar all the way round fixed by rivets, it is also foldable upwards and hinged on the underside to allow this, this is done as to allow the tool to be fitted in-between two profiles at start, the corner tool is then dragged up the two profiles and an even and precise plastered angle is achieved, the profile which is at 90 degrees is then moved to be parallel and in line with the remaining profile to plaster a flat wall section, Figure 8 shows straight edge In figure 1, plaster profile unit I indudes a sfraight edge, this slots 01 between the two erect profiles so that it s outer two edges are guided by the inner two edges of the main body of the profiles, it can then be draw up and down in between the two profilesto give an even coat of plaster at the given thickness, Figure 9 shows winding mechanism In figure 1, a plaster profile unit I includes a ceiling brace number I is fitted to the top end of number 5 by means of an aluminium block and a locking screw to hold in place The bottom of number 5 vs fitted to the top of number 6 by means of same method. The bottom of number6 isflttedtotheopof number7also usingthesame methot Figure 10 sho winding mechanism In figure 1, a plaster profile unit I includes hthe straightedge number 161s used Figure 11 shows winding mechanism In figure l.a plaster profile unit lindudes howthecomertool number 17 is used Erection of profiles Measure the ceiling height and construct the profile as in fIgure 1 and wind profile up with winding mechanism until rough height desired.

Make sure the two thickness s 14 are wound in tight and lift up profile to the wall needing plaster. In a corner of the room use the angle tool to aid set up as in hold in corner and roughly erect the profile so the edge of the corner tool is touching the inside edge of the main body on the top of the bottom floor brace and the feet of the corner tool touching the floor with the stabilising bar on so the corner tool sits level and touches the back plate main profile..

With the two thickness screws touching the wall roughly wind up the profile so as it is pushing on the ceiling and cen stand proud on its own with spirit level check vertical height and with plumb line check horizontal level. If floor is un-level use adjustable feet to ensure profile is vertically level. When this has been done turn winding mechanism handle a further quarter of a turn to ensure profile is erect and can not move, screw in nut number 10 to hold winding mechanism in place. Do the same to a second profile but at right angtestotheflrst profile, as in figure 10 To confinue plastering the wall remove one of the profiles and at a given distance of how long the straight edge is. The straight edge should be touching both inside edges of main body of profile and be sitting flush on back plate the string tine is run along the top front edge of the profile and along the second when the sbing runs level along both profiles the desired setting has been done, set up second profile asto the flias in figure 11.

When erected there is a rubber strip number 2 on top of ceiling brace toallowtheprofileflgure Ito tightlygnp the ceiling and still bein an upright position fur alignment to be cnpleted before full lightening of profile -A plumb bob can be used to aid in the ease of erection by using the pre drilled hole in the underside of numberl.

A sprit level cradle can be used on the pre cut slot in main body number 9 to ease erection of profile.

The adjustable feet number 15 fitted to the bottom of numberl 2 insures that the profile as ere straight and true on un-even floors.

Two adjustable sae number l4are fitted to the each end of the main bodyofnumbersll and9,when screwed intheypratrudeoutof the back of the profile to the right thickness for a standard minimum thickness of plaster to cover a wall.

One number 10 is a bolt flush with main body which protrudes to be the minimum thickness of plaster needed.

Astiaight edge number 16 is used in between two or more profiles to ensure a flat even coat of plaster An angle edge number 17 is used between two profiles to plaster a precise, square, even internal angle, the angle tool is hinged across itto altowease of use and removal, bylifting itup and pushing in at the same lime,there is a turning bar underneath so when in between profiles it can be turned and the corner tool is now rigid.

To gain enough pressure for the profile to stay upright an internal winding mechanism number 18 is housed in main body number 1 0,this is made of a rack and pinion fixed inside of main body 8 the proud plate of this slots in beten the shroud and number 3, when the winding mechanism is turned this pushes number I toward the ceiling, when desired pressure and straightness is gained a tightening screw fitted through number 11 holds the profile in place.

String knee are fitted to each end of nurnberl to ensure straightness of one profile to another in either direction.

A. ceiling brace attachment can be saewed into centre of number Ito enable erection of profile when joists are running in opposite direction..

The profile is made to work with an aierage height room however if higher the extension piece or pieces can be fitted to allow use in these. The main lower body' can be removed and the profile can then be used in corundion with smaller areas of height Two or more profiles can be used to plaster a given secon or a whole room can prepped as to plaster an entire room thus saving on time and monies incurred In main figure 1 numbers 45,6,7 form the back plate of the profile the edges are bevelled towards the back to allow ease of removal from wall, the straight edge also runs up and down these to Insure an even mat, of plaster
