AN INJECTOR
This invention relates to an injector, and in particular to an injector for injecting insulant material into a cavity of interest formed between first and second masonry constructions.
It is known to inject an insulant material into a cavity, e.g. a cavity formed between external and internal walls of a building so as to reduce the thermal transmittance between the external and internal walls.
According to a first aspect of the invention there is provided an injector for injecting insulant material into a cavity of interest formed between first and second masonry constructions, the injector comprising:
an injector body configured to house an insulant material; a stop face positioned at one end of the injector body, the stop face being abuttable in use against a surface of a first masonry construction; and an injecting member extending from the stop face to distribute the insulant material from the injector body to within the cavity of interest, the injecting member extending from the stop face by a length of at least 140mm.
The injecting member extending from the stop face by a length of at least 140mm restricts the distribution of insulant material to the cavity of interest by preventing the insulant material from spilling into an adjacent cavity, e.g. an adjacent cavity extending substantially perpendicularly to the cavity of interest such as might arise at a corner in a masonry construction.
In this way, the arrangement of the injecting member permits a focussed distribution of the insulant material.
It will be understood that the first and second masonry constructions may be any type of masonry walls, such as an external brick wall and/or an internal blockwork wall.
Typically, a first external masonry construction has a depth of 100mm. Therefore the injecting member extending from the stop face by a length of at least 140mm allows the injecting member to focus distribution of the insulant material within the cavity of interest when the adjacent cavity has a depth of 40mm.
Preferably the injecting member extends from the stop face by a length of between 140mm and 260mm.
Such an arrangement permits use of the injecting member with a range of adjacent cavity depths and/or a range of depths of the first masonry construction, while providing the aforementioned focussed distribution of the insulant material.
For example, such an injecting member could be used with an adjacent cavity depth of anywhere between 40mm and 150mm when the first external masonry construction depth is 100mm.
The injecting member may extend from the stop face by a length of 200mm or by a length of 260mm.
There now follows a brief description of preferred embodiments of the invention, by way of a non4imiting example, with reference being made to the accompanying drawings in which:
Figure 1 shows a perspective view of an injector according to an embodiment of the invention in use;
Figure 2 shows an injecting member of the injector shown in Figure 1; and Figure 3 shows a further schematic, partially-sectioned view of the injector shown in Figure 1 is use.
An injector according to an embodiment of the invention is designated generally by the reference numeral 10.
The injector 10 includes an injector body 12 and a stop face 14 positioned at one end of the injector body 12. The injector 10 also includes an injecting member 16 that extends from the stop face 14.
In the embodiment shown, the injecting member 16 extends from the stop face 14 by a length L of 200mm. In other embodiments of the invention (not shown), the injecting member 16 may extend from the stop face 14 by any length L between 140mm and 260mm. For example, the injecting member 16 may extend from the stop face 14 by a length L of 200mm.
As shown in more detail in Figure 2, the injecting member 16 includes a hollow body 18 that extends between an upstream end 20 and a downstream end 22 of the injecting member 16. In the embodiment shown, the hollow body 18 is an elongate nozzle 24.
The injector 10 further includes a first attachment member 26 in the form of a fastener 28. The fastener 28 includes a head 30 having first and second faces 32, 34 lying at opposite sides of the head 30. The fastener 28 also includes a support portion 36 that extends from the first face 32.
The support portion 36 extends from the first face 32 and forms the stop face 14. More particularly, the stop face 14 as has larger diameter than the hollow body 18.
The support portion 36 receives the nozzle 24 so as to provide an interference fit between the fastener 28 and the nozzle 24, thus securing the nozzle 24 to the fastener 28.
The nozzle 24 as it extends from the support portion 36 defines the length L of the injecting member 16. The stop face 14 is fixedly coupled with the injecting member 16. In other embodiments of the invention (not shown), the stop face 14 may instead form part of the injector body 12. For example, the stop face 14 may be defined by an outer face of the injector body 12 which receives the injecting member 16. Alternatively, the first face 32 of the support portion 36 may define the stop face 14.
The fastener 28 may be secured to the nozzle 24 by other means, e.g. by an adhesive or by welding. Alternatively, the nozzle 24 and the fastener 28 may be integrally formed.
The fastener 28 also includes a threaded portion 38 extending from the second face 34 of the head 30.
The nozzle 24 is made from stainless steel, but may instead be made from a non-ferrous metal
The fastener 28 is made from brass. Alternatively, the fastener 28 may be made from a non-ferrous metal.
As shown in Figures 1 and 3, the injector body 12 has a housing 40 and an outlet 42 extending from the housing 40. The outlet 42 includes a second attachment member (not shown) that is mutually engageable with the first attachment member 26.
The second attachment member is a threaded hole that receives the threaded portion 38 of the fastener 28.
The injector body 12 also includes first, second and third inlets 44a, 44b, 44c extending from the housing 40 and arranged in fluid communication therewith. The first inlet 44a is an insulant material inlet, the second inlet 44b is a binding agent inlet, and the third inlet 44c is a carrier fluid inlet.
In other embodiments of the invention (not shown) the housing 40 may have a different number of inlets extending therefrom.
The injector body 12 is made from stainless steel, but may instead be made from a nonferrous metal.
Figure 3 shows the injector 10 described herein above in use to inject insulant material (not shown) into a cavity of interest 46. The cavity of interest 46 is formed between first and second masonry constructions 48a, 48b.
In the embodiment shown, the first masonry construction 48a is an external wall 50 of a building, the external wall 50 being made from bricks. Meanwhile the second masonry construction 48b is an internal wall 52 made from concrete blocks. The first and second masonry constructions 48a, 48b may take other forms and may be made from any suitable masonry material, such as stone or granite.
The internal wall 52 defines an internal corner 54 where the internal wall 52 changes direction. More specifically, the internal wall 52 has first and second internal wall portions 52a, 52b that meet one another at the internal corner 54. In the embodiment shown, the first and second internal wall portions 52a, 52b meet one another at 90°, thus forming a right angled internal corner 54.
In a similar manner, the external wall 50 has first and second external wall portions 50a, 50b that meet one another at an external corner 56.
The first external wall portion 50a and the first internal wall portion 52a are spaced from one another and so form the cavity of interest 46 therebetween. Meanwhile, the second external wall portion 50b and the second internal wall portion 52b form an adjacent cavity
58. The cavity of interest 46 and the adjacent cavity 58 meet one another at a boundary 60 that extends between the internal corner 54 and the first external wall portion 52a, as shown in Figure 3.
In other embodiments of the invention (not shown), the external wall 50 may not have an external corner 56. For example, the external wall 50 may be a party wall (not shown) which joins two buildings to one another. In this instance, the cavity of interest 46 may be formed between a party internal wall which meets the external wall 50 to form a party corner.
In still further embodiments of the invention (not shown), the first and second internal wall portions 52a, 52b and/or the first and second external wall portions 50a, 50b may meet one another at an angle other than 90°.
In use, the injecting member 16 is inserted into an opening 62 formed within the second external wall portion 50b until the stop face 14 abuts against an external surface 64 of the second external wall portion 50b.
The opening 62 may be formed by drilling a hole in the external wall 50. The hole has a diameter less than the diameter of the head 30.
The injecting member 16 extends from the stop face 14 into the cavity of interest 46 and beyond the internal corner 54. The downstream end 22 of the injecting member 16 is therefore located beyond the boundary 60, such that it also extends beyond the adjacent cavity 58.
In other embodiments of the invention (not shown), the injecting member 16 may instead extend from the stop face 14 into the cavity of interest 46 such that it downstream end 22 lies coincident with the boundary 60.
In any event, the injector 10 is then operated so as to force the insulant material from the housing 40 of the injector body 12 towards the outlet 42 thereof.
The insulant material is then forced through the nozzle 24 at the upstream end 20 of the injecting member 16 and exits the nozzle 24 at the downstream end 22 of the injecting member 16. The insulant material thereafter enters the cavity of interest 46. Eventually, the cavity of interest 46 is filled with the insulant material.
Meanwhile, the location of the downstream end 22 of the injecting member 16 relative to the boundary 60 and associated internal corner 54 means that the likelihood of the insulant material crossing the boundary 60 and entering into the adjacent cavity 58 is very low.
The injecting member 16 can then be removed from the cavity of interest 46 and inserted into another opening (not shown) formed within the first external wall portion 50a (or the party internal wall, if appropriate).
The injecting member 16 can then be operated in the same manner as described above so as to distribute insulant material within the adjacent cavity 58 (which is now the cavity of interest) so that it now extends into the former adjacent cavity 58.
In the embodiment shown in Figure 3, the external wall 50 has a depth Di of 100mm, while the adjacent cavity 58 has a depth D2 of 60mm. Thus, the hollow body 18 (i.e. the injector member 16) with a length L, between the stop face 14 and the downstream end 22, of 200mm results in the nozzle 24 extending beyond the internal corner 54, i.e. beyond the boundary 60, by 40mm. In other embodiments of the invention (not shown), the external wall 50 and/or adjacent cavity 58 may have differing depths. Indeed, the injector 10 could be used in a wall which has an adjacent cavity depth D2 of up to 90mm to allow for at least 10mm clearance between the downstream end 22 and the boundary 60. The injector 10 could also be used in a wall which has an adjacent cavity depth D2 of up to 100mm where little or no clearance is present between the downstream end 22 and the boundary 60.
In a typical housing structure, the external wall 50 is made from a brick that has a depth Di of 100mm. Moreover, normally the cavity of interest 46 and the adjacent cavity 58 have the same depth as one another, i.e. the “wall cavity”. The wall cavity may have a depth of anywhere between 40mm and 150mm when the external wall 50 is made from a brick that has a depth of 100mm.
By way of example, a housing structure that was built in the UK before 2006 typically has a wall cavity of 60mm, while a house that was built in the UK after 2006 typically has a wall cavity of 80mm.
Accordingly, an injecting member 16 with a length L of 200mm is preferably used to inject insulant material into a wall cavity of between 40 and 90 mm. Meanwhile, an injecting member 16 with a length L of 260mm would preferably be used to inject insulant material into a wall cavity of between 90 and 150 mm. Thus, it is preferred that the downstream end 22 of the nozzle 24 extends beyond the internal corner 54, i.e. beyond the boundary 60, by approximately 10mm to 40mm.
