Abstract

A template system for use in building brick piers comprises a pair of plywood templates connected by plumb lines. The lower template is fixed to the floor and the upper template is fixed to support beams. The lower template is recessed to define the size of the brick pier with the bricks being located inside the recess. The pier may be any cross-sectional shape as long as the upper and lower templates define the same cross-section. <IMAGE>

Description

THE PROLINE SYSTEM FOR PRE-BUILD AND IN-SITU BRICK PIERS 1. When built, brick piers have a tendency to deviate in width from top to bottom and in many cases twist appears in their construction. By using this system the number of piers produced in a given period and the quality of those piers increases dramatically. When the piers are erected using this system and are lined and plumbed as in fig. 4, the problems of deviation in width and the twisting mentioned above will be eliminated.

2. The system is basically a series of drop lines from two plywood templates.

One directly above the other. The profile at the head is held by timber support beams whilst the one below is fixed to the floor. Both template and base should be made of marine ply to avoid any possible movement in the plywood resulting from dampness. The template base is recessed to the size of the pier required and the bricks sit inside the recess insuring accurate setting out of all piers.

3. The template bases and heads are interchangeable and can be taken off the base plate and head support if any variation to the size of the piers is required or if the programmed works demand more of another type of pier.

4. The base plates stay bolted to the floor and the blockwork walls to the support beams should also be semi-permanent, everything else on the set up is immediately interchangeable.

5. Fig. 4 shows a jig set up for the prebuit piers whilst fig. 5 shows a template set up for piers build in-situ.

The lifting facililities for the pre-built piers would be designed by others, however this system does accommodate any type of lifting facility and concrete bases to the piers which, if required, will fit into the template recess in the same manner as fitting into the brickwork.

There are no dimensions ony any of the drawings as the pier requirements will vary from contract to contract. The set-up is designed to accommodate any pier both in size or shape and will also incorporate any reinforcing for lifting purposes etc.

This sytem enables the bricklayer to achieve quality, quantity and as a result of the increased output cuts costs across the board.

TEXTUAL MATTER APPLICATION NO: GB 9400233.4 TITLE- THE PROLINE SYSTEM Fig. 1 - Head Template.

Drilled on each corner of external and internal for lines.

Nylon drop lines.

Templates interchangeable.

Permanent baseplate bolted to floor for long term construction.

Fig. 2 - Head Template Support Beams.

Move to one side for removal of piers once constructed.

Head Template (1) screwed to support piece (2) and bolted to support beam (3).

Fig. 3 - Base and head trees can be used for any shape required, basic shapes of templates as shown on 1. 2 and 3.

All bases would be cut out to accurate template size.

All head templates would be solid with template holes drilled for drop lines.

All base templates and head templates are in the same size.

Fig. 4 - Support beam bolt holes both ends of timber plate.

Blockwall wall supports on both sides.

Plywood base plates are permanent or interchangeable.

Claims

THE PROUNE SYSTEM

FOR PRE-BUILD AND IN-SITU BRICK PIERS 1. When built, brick piers have a tendency to deviate in width from top to bottom and In many cases twist appears In their construction, By using this system the number of plers produced In a glven period and the quality of those piers increases dramatically. When the piers are erected using this system and are lined and plumbed as In fig, 4, the problems of deviation in width and the twlsting mentioned above will be eliminated.
2 The system is basically a series of drop lines from two plywood templates.

One directly above the other. The profile at the head Is held by timber support beams whilst the one below is fixed to the floor. Both template and base should be made of marine ply to avoid any possible movement in the piywood resulting from dampness. The template base is recessed to the size of the pier required and the bricks sit inside the recess insuring accurate setting out of all piers.
3. The template bases and heads are interchangeable and can be taken off the base plate and head support if any variation to the size of the piers Is required or If the programmed works demand more of another type of pier.
4. The base plates stay bolted to the floor and the blockwork walls to the support beams should also be semi-permanent, everything else on the set up is Immediately Interchangeable.
5. Fig. 4 shows a fig set up for the pre-buit piers whilst fig. 5 shows a template set up for piers bulld in-situ.

The lifting focililities for the pre-bullt piers would be designed by others, however this system does accommodate any type of lifting facility and concrete bases to the piers which, If required, will flt Into the template recess In the same manner as fitting into the brickwork.

There are no dimensions ony any of the drawings as the pier requirements will vary from contract to contract. The set-up Is designed to accommodate any pier both In size or shape and will also incorporate any reinforcing for lifting purposes etc.

This sytem enables the bricklayer to achleve quality, quantity and as a result of the increased output cuts costs across the board.

Amendments to the claims have been filed as follows 1. The system is basically an apparatus which holds building lines in a vertical position which enables brick piers to be built without "twist" and within British Standards tolerances. This method has been used in the construction of approximately 1,400 piers all of which were constructed to a standard within British Standard tolerances without any being rejected.
