Abstract

The boxing 1 shall be prefabricated and marketted in flat-pack form. There shall be at least two adjacent boards with at least one flexible hinged joint 2 which may have a suitable adhesive applied to the mating faces. Edge fixing strips 3 may be utilised for securing to the walls. A shoe 4 manufactured in impervious material shall be fitted to the bottom of the boxing; this holds the boxing in shape, acts as a damp-proof membrane and has facility for fixing to the walls. Intermediate brackets may be provided; these hold the boxing in shape and have facility for fixing to the walls. Once assembled the boxing is self-supporting and will provide a strong boxing around the pipe(s) to be covered; the boxing may have a skim coat of plaster and decoration applied or may be self finished which may or may not be decorated.

Description

PRE-FABRICATED PIPE BOXING This invention relates to pipe boxings which are pre-fabricated, are marketted in flat pack form, are foldable into shape, and, are self supporting in erection/installation with facility for quick fixing into position. The boxing may be provided in varying widths and may or may not be self-finished.

The purpose of this invention is to provide by simple and quick means a surround to internal soil or service pipes in building constructions. The normal means of fabrication for such boxings is for a strong timber framework to be covered by boarding, usually plasterboard, which in turn is usually covered with plaster and paint or paper decoration. By the invention the timber framework is eliminated and a pre-fabricated pack foldable into a boxing which has inbuilt methods of fixing to walls is envisaged. Once assembled for erection the boxing will be self-supporting for installation and will provide a strong boxing around the pipes to be covered; the boxing may have a skim coat of plaster and decoration applied or may be self-finished which may or may not be decorated. A further advantage is that by the elimination of the timber framework the boxing can be narrower and neater.

A pipe boxing which is prefabriciated and marketted in flat-pack form using suitable board incorporating a hinged joint or joints, which may be secured with adhesive, to permit folding to shape, also, incorporating methods of fixing to the walls.

A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings in which: A Figure 1 shows in perspective the erected pipe boxing in usual form utilising two adjacent boards set at 90" or thereabouts Figure 2 shows in perspective the erected pipe boxing in an alternative form utilising more than two boards.

Figure 3 illustrates alternative flat-pack forms of the boxing together with alternative hinged joint construction applicable to boxing L shaped on plan forming an angle of 90" or thereabouts.

Figure 4 illustrates a flat-pack form of the boxing together with hinged joint construction applicable to boxings having more than two adjacent boards.

Figure 5 illustrates examples of tongue and grooved, rebated, or, filler tongued joint faces.

Figure 6 illustrates the alternative edge fixing strips.

Figure 7 illustrates the shoe.

Figure 8 illustrates an intermediate bracket.

The boxing 1 shall be pre-fabricated in flat-pack forms as shown in Figures 3 and 4. The envisaged alternative pack formats 10, 11, 12, 13, 14 and 15 are shown in Figure 3 and envisaged pack format 16 is shown in Figure 4.

The boxing 1 is formed by adjoining pieces of suitable board joined longitudinally by a flexible hinge. The boards fold at the hinged joint 2 or joints 2 to form the boxing; adhesive may or may not be applied to the mating faces of the hinged joint faces 2. The edges of the boards remote from the hinge(s) may each have a flexible edge fixing strip 3 secured to the boards and positionable for fixing to the walls.

In the preferred and more usual version of the boxing 1 there would be two adjacent boards which would fold to a form L shaped on plan forming an angle of 90" or thereabouts as shown in Figure 1 and 3. However three or more boards may be arranged to form a boxing of other relevant plan outline as shown in Figures 2 and 4.

The board edges at the hinged joints 2 may be mitred to form a junction at 90" or thereabouts as shown in Figure 3, configurations 2/1 and 2/3, or, other relevant angle(s) as shown in Figure 4, configuration 2/5. Alternatively the board edges may be square and form a junction at 900 or thereabouts as shown in Figure 3, configurations 2/2 and 2/4.

The mating faces of the board edges in the mitred and square joints as afore described may be plainfaced as shown in Figures 3 and 4, configurations 2/1 to 2/5 inclusive, or, may be tongued and grooved, or, one or both faces may be rebated to each receive the other. Examples of tongued and grooved or rebated joints are as shown in Figure 5, configurations 5/1 to 5/4 inclusive.

Possible individual configurations are as follows: mitred tongued and grooved joint,configuration 5/1; mitred rebated joint, configuration 5/2; square tongued and groove joint, configuration 5/3; square rebated joint, configuration 5/4.

Alternatively the tonguesigrooved or rebates may take a form that is the reverse of those shown in the aforesaid configurations 5/1 to 5/4. In adddition, one or both of the mating faces in the mitred or square joints may be grooved or recessed of any shape which when filled by the application of an adhesive/filler forms a tongue key which when set stiffens and supports the joint. Examples of mitred and square filler tongued joints are as shown in Figure 5, configurations 5/5 and 5/6 respectively.

The hinge material shall be strong, flexible, fabric and shall be bonded in or to the adjacent boards, also, it shall usually be continuous along the length of the boxing but may be intermittent. The hinge material may cover part or all of the face of the boxing to which it is affixed and may be affixed to the external faces of the boxing as shown in Figure 3, configurations 2/1 and 2/2, and, as shown in figure 4, configuration 2/5; alternatively the hinge material may be affixed to the internal faces of the boxing as shown in Figure 3, configurations 2/3 and 2/4.

Hinge material which covers the whole of the external faces of the boxing may be aesthetically acceptable to be the surface finish which may or may not be decorated.

The boxing 1 shall, by the preferred method, be secured to the walls by means of the built in edge fixing strips 3 hereafter described. However, alternatively, the edge of the boards abutting the walls may be secured by nailing to timber battens previously fixed to the walls as shown in Figure 6, configuration 3/4.

The edge fixing strips 3 shall be a strong flexible fabric which shall be bonded in or to the adjacent boards as shown in Figure 6. The strips may be continous along the length of the boxing but alternatively may have gaps to permit the fitting of the intermediate brackets 5, or, may be intermittent. The strips 3 may be affixed to the internal faces of the boxing as shown in configuration 3/1, or, affixed to the external faces as shown in configuration 3/2, or, a combination of the afore described and affixed to both internal and external faces as shown in configuration 3/3, all as detailed in Figure 6.

At the base of the boxing 1 there may be shoe 4 as shown in Figures 1 and 7.

The shoe 4 shall have a channel in the top edge to receive the bottom edges of the boxing boards, and, it shall be formed in strong impervious material to provide a firm bracket and to act as a damp proof membrane to the bottom of the boxing. At each end of the shoe there shall be an ear for fixing to the walls.

Intermediate brackets 5 may be provided as shown in Figure 8. These may be fitted to support the boxing 1 at the top and intermittently along the length of the boxing. The brackets shall be formed in a strong impervious material. At each end of the bracket arms there shall be a lug to locate around the edges of the boxing boards, also, there shall be an ear for fixing to the walls.
