Description

"A modular construction system and a constructional element
for use in the modular construction system"
The present invention relates to a modular construction system, and to a constructional element for use in the modular construction system, and in particular, the invention relates to a modular construction system for constructing a series of building service cavities in or on a wall in a building, although the invention is not to be so limited, and the invention also relates to but is not limited to a constructional element for use in stud partitioning in a building. The modular construction system may be used for constructing a wall, for example a partition wall.
As used herein the term wall shall also be construed as extending to floors and ceilings unless otherwise indicated.
According to the invention there is provided a constructional element comprising an elongated member defining a first face and an opposite second face, and at least two longitudinally spaced apart spacer elements projecting outwardly from the first face to define with the first face a building services accommodating recess.
Advantageously, the constructional element of the present invention may result in a reduction of thermal transfer occurring by means of thermal bridging. The spacer elements reduce the surface area of the constructional element that is in direct contact with an external wall or other substrate. The reduction in surface area contact between the constructional element and an external wall/other substrate may result in the reduction of heat loss. It is envisaged that the constructional element of the present invention may reduce thermal bridging by up to 90% compared to a flat panel that would be in direct contact with an external wall/other substrate over its full area.
Preferably, the second face of the elongated member is adapted for receiving a panel element.
In one embodiment of the invention the at least two spacer elements are located adjacent respective opposite ends of the elongated member.
In another embodiment of the invention a plurality of spacer elements project from the first face of the elongated member, and adjacent spacer elements define with the first face of the elongated member respective building services accommodating recesses.
Preferably, at least one of the spacer elements is adapted for accommodating a fixing element for securing the elongated member to another constructional element or to an adjacent wall, floor or ceiling.
Preferably, each spacer element defines a first abutment face for abutting an adjacent abutment face of a spacer element of an adjacent constructional element or a wall, a floor or a ceiling for spacing the first face of the elongated member from the corresponding constructional element, wall, floor or ceiling, the first abutment face of each spacer element extending parallel to the first face of the elongated member.
The first abutment face of the spacer element may be coated with suitable materials. Suitable materials may include packers, a (telescopic) size adjustment mechanism, (heat) insulating materials, and sound proofing materials amongst others. Advantageously, coating the first abutment face of the spacer element with an insulating material may further help to reduce the occurrence of thermal bridging.
Coating materials may be applied to the first abutment face of the spacer element using a double- sided adhesive layer. The double-sided adhesive tape may also be used to hold a sheeting material in place prior to a mechanical fixing. This may be particularly advantageous in overhead/vertical positions. Additionally, a double-sided adhesive layer may be applied to the second surface of the construction element allowing a sheet material to be applied thereto. Preferably, a first bore extends through at least one of the spacer elements between the first abutment face thereof and the second face of the elongated member for accommodating a fixing element therethrough. The bore may be a self-aligning bore, i.e. it may aid passage of a fixing means such as a screw or nail in to said bore. In another embodiment of the invention each abutment face defines a pair of opposite second abutment faces extending parallel to the elongated member for abutting abutment faces of respective adjacent constructional elements. Advantageously, a second bore extends through at least one of the spacer elements between the second abutment faces thereof for accommodating a fixing element therethrough.
In a further embodiment of the invention each spacer element comprises a pair of opposite third abutment faces extending transversely of the elongated member, at least one of the third abutment faces being adapted for engaging an adjacent constructional element. Preferably, one of the third abutment faces defines with the first face of the constructional element and a third abutment face of an adjacent spacer element extending from the first face of the elongated member the or one of the building services accommodating recesses. Advantageously, a third bore extends through at least one of the spacer elements between the opposite third abutment faces for accommodating a fixing element therethrough.
Ideally, each one of the first, second and third bores are counter-bored. The first, second and third bores may be counter-bored for self-alignment. Each one of the first, second and third bores and their respective counter-bores may define a substantially funnel-like bore profile. This may be particularly advantageous in guiding a fixing means such as a screw or nail in to said bore.
In another embodiment of the invention at least one of the first, second and third abutment faces of at least one of the spacer elements is provided with an alignment means for aligning the abutment face thereof with an abutment face of a spacer element of an adjacent constructional element. Preferably, each alignment means comprises a dowel receiving bore, a Lamello Biscuit, tongue and groove, or combinations thereof.
The invention also provides a modular system comprising a plurality of the constructional elements adapted to form a wall with a plurality of parallel constructional elements joined by transversely extending constructional elements with third abutment faces of the spacer elements of the transverse constructional elements abutting second abutment faces of adjacent spacer elements of the parallel constructional elements. The wall may be a partition wall.
The invention also provides a modular system comprising a plurality of the constructional elements adapted to form a series of building service cavities in or on a wall in a building with a plurality of parallel constructional elements joined by transversely extending constructional elements with third abutment faces of the spacer elements of the transverse constructional elements abutting second abutment faces of adjacent spacer elements of the parallel constructional elements. The invention further provides a modular construction system comprising a plurality of the constructional elements adapted to form a wall with the constructional elements arranged in pairs with the first abutment faces of the adjacent spacer elements abutting each other, and at least some of the spacer elements of the respective pairs of constructional elements being secured by respective fixing elements, adjacent spacer elements of the constructional elements of each pair defining with the adjacent first faces of the elongated members of each pair of constructional elements respective ones of the building services accommodating recess. The wall may be a partition wall.
The invention further provides for a modular construction system comprising a plurality of the constructional elements according to the present invention, wherein
the constructional elements are adapted to form a series of building service cavities in or on a wall in a building, with the constructional elements arranged in pairs with the first abutment faces of the adjacent spacer elements abutting each other, at least some of the spacer elements of the respective pairs of constructional elements being secured by respective fixing elements, and
adjacent spacer elements of the constructional elements of each pair defining with the adjacent first faces of the elongated members of each pair of constructional elements respective building services accommodating recesses. In one embodiment of the invention a panel element is secured to the second faces of the elongated members of each adjacent pair.
In another embodiment of the invention adjacent pairs of the constructional elements are joined by transversely extending constructional elements.
The invention also provides a studded wall comprising a panel element secured to and spaced apart from the wall by a plurality of the constructional elements spaced apart from each other with the first abutment faces of the spacer elements abutting the wall.
In a further aspect, the present invention provides for use of a constructional element according to the present invention to reduce the occurrence of thermal bridging in a building.

Referring to the drawings and initially to Figs. 1 to 6, there is illustrated a constructional element according to the invention, indicated generally by the reference numeral 1 , of a modular construction system which is also according to the invention, and is illustrated in Figs. 14 to 17 where the modular construction system is illustrated for forming partition walls 2 and 60 and studded walls 4. However, before describing the modular construction system, the constructional elements according to the invention of the system will first be described.
The constructional element 1 , which is illustrated in Figs. 1 to 6, comprises an elongated member 5 defining a first major face 7 and an opposite second major face 8. A plurality of spacer elements 10 project from the first major face 7 of the elongated member 5 at spaced apart locations along the elongated member 5. Adjacent ones of the spacer elements 10 define with the first major face 7 of the elongated member 5 respective building services accommodating recesses 1 1 for
accommodating building services ducts, conduits, pipes and the like through the partition wall 2 or the studded wall 4 as will be described in more detail below. The second major surface 8 of the elongated member 5 is adapted for receiving a panel, such as a wall panel, a floor panel, a ceiling panel or the like as will be described below. In this embodiment of the invention the constructional element 1 is manufactured from oriented strand board, and typically, is formed by a suitable moulding process. Although needless to say the constructional element may be manufactured by any other suitable process.
Each spacer element 10 defines a first abutment face 12, a pair of second abutment faces 14, and a pair of third abutment faces 15. A first bore 18 extends through each spacer element 10 and the elongated member 5 between the first abutment face 12 of each spacer element 10 and the second face 8 of the elongated member 5 for accommodating a fixing element therethrough, for example, a screw, bolt or the like, for in turn securing the spacer element 10 to another elongated member, a wall, floor, ceiling or the like. A second bore 19 extends through at least some of the spacer elements 10 between the second abutment faces 14 for accommodating a fixing element, for example, a screw, bolt or the like, for in turn securing the spacer element 10 to another elongated member, a wall, floor, ceiling or the like. A third bore 20 extends through some of the spacer elements 10 between the third abutment faces 15 also for accommodating a fixing element, namely, a screw, bolt or the like for securing the constructional element 1 to another constructional element. Each first, second and third bore 18, 19 and 20 is counter-bored at 21 for receiving a closure cap for concealing the head of a screw, bolt or the like in the corresponding one of the first, second and third bores 18, 19 and 20.
The counter bore 21 of each first, second and third bore 18, 19 and 20 may progressively decrease in diameter until it is the same diameter as the first, second or third bore 18, 19 and 20. This may result in a funnel-like bore profile, e.g. a bore having a conical mouth 21 and a narrow stem 18. This may be particularly advantageous as a screw, nail or other fixing means can be easily guided into the bore 18 using the conical profile of the mouth at 21. The conical profile of the mouth at 21 may comprise a coating insert, such as a metal insert. An alignment means for facilitating alignment of the constructional element 1 with another constructional element comprises a plurality of alignment bores 23 formed in the first abutment face 12 and in some of the second and third abutment faces 14 and 15 for receiving alignment dowels (not shown) for engaging corresponding alignment bores in an adjacent constructional element for aligning the constructional element 1 with the other constructional element. The alignment means may be provided by any other suitable means, such as Lamello Biscuit, tongue and groove or the like.
Referring now to Figs. 7 to 12, there is illustrated a constructional element 30 also according to the invention, which forms a part of the modular constructional system. The constructional element 30 is substantially similar to the constructional element 1 and similar components are identified by the same reference numerals. The only difference between the constructional element 30 and the constructional element 1 is that the constructional element 30 is provided with only two spacer elements 10 which are located adjacent the respective opposite ends of the elongated member 5. Turning now to Figs. 14 and 15, a modular constructional system, which is indicated generally by the reference numeral 35, for use in the construction of the partition wall 2 is constructed from the constructional elements 1 and the constructional elements 30. Each constructional element 1 is secured to a plurality of adjacent constructional elements 30 by the respective spacer elements 10 of the constructional elements 1 and 30. One of the second abutment faces 14 of each spacer element 10 of the constructional element 1 is located abutting a corresponding third abutment face 15 of the adjacent spacer element 10 of the corresponding constructional element 30. Dowels (not shown) engaged in the corresponding alignment bores 23 of the adjacent spacer elements 10 align the constructional elements 30 with the constructional elements 1. Fixing elements, for example, screws or bolts through the second bores 14 of the constructional element 1 and the third bores 20 of the spacer elements 10 of the constructional elements 30 secure the constructional elements 1 and the constructional elements 30 together.
When the constructional elements 1 and 30 have been assembled and secured together as illustrated in Fig. 15 to form the modular system 35, the modular system is then erected and batons 37 are secured to the modular system 35 extending parallel to the constructional elements 1. The batons 37 are located adjacent and secured to the first abutment faces 12 of the spacer elements 10 of the constructional elements 1 and 30. Panels 38 of any suitable material and typically, plasterboard are then secured to the modular system 35. The panels 38 are secured to the second faces 8 of the elongated members 5 of the constructional elements 1 and 30 on one side of the modular system 35, and to the batons 37 on the other side of the modular system 35. Prior to securing the panels 38 to the modular system 35, building services, such as pipes 39, for example, water pipes, conduits 40, for example cable carrying conduits 40, and ducts 41 , for example, air conditioning ducts are located in the building services accommodating recesses 1 1 of the modular system 35.
Referring now to Fig. 16, each studded wall 4 comprises a wall 50 of masonry wall of a building and a plurality of panels 51 , typically of plasterboard, which are secured to and spaced apart from the wall 50 by a plurality of the constructional elements 1 . The first abutment faces 12 of the spacer elements 10 abut the wall 50 and define with the wall 50 and the first major face 7 of the corresponding elongated members 5 the building service accommodating recesses 1 1 for accommodating building services, such as, for example, pipes, conduits and ducts. The constructional elements 1 are secured to the wall 50 by screws or bolts extending through the first bores 18 of the respective constructional elements 1 . While the wall 50 has been described as being of masonry, the wall 50 may be of any suitable material, for example the wall 50 could be formed of timber frame or timber panel construction or any other type of wall makeup.
Referring now to Fig. 17, there is illustrated an alternative construction of partition wall 60 whereby the constructional elements 1 and the constructional elements 30 are arranged in pairs so that adjacent spacer elements 10 define with the first major faces 7 of the corresponding elongated members 5 building services accommodating recesses 1 1. Otherwise, the construction of the partition wall 60 is substantially similar to that of the partition wall 2. Referring now to Fig. 18 there is illustrated a constructional element according to another embodiment of the invention indicated generally by the reference numeral 80. The constructional element is substantially similar to the constructional element 1 and similar components are identified by the same reference numerals. The main difference between the constructional element 80 and the constructional element 1 is that heat insulation material 81 is located between the spacer elements 10, and beneath the abutment faces 12 of the spacer elements 10. The heat insulating material may be any suitable heat insulation material and typically, would be a wood fibre insulating material, which could easily be cut out to create a bypass for any service if and when required.
Otherwise, the constructional element 80 is similar to the constructional element 1 and its use is likewise similar.
While the constructional elements 1 , and 30 and 80 have been described for the construction of studded partition walls and studded masonry walls, it is envisaged that the constructional elements 1 and 30 may be used for supporting ceiling panels in order to accommodate building services between the ceiling panel and either rafters of the ceiling or a poured concrete floor of an upper floor which forms the ceiling of a lower floor, and it is also envisaged that the constructional elements 1 and 30 may be used for supporting a floor above a masonry floor or floor of the other construction for similarly accommodating building services between the floor and the masonry floor.
While the constructional elements have been described as being of oriented strand board, the constructional elements may be of any other suitable material, whether timber, plastics, and indeed, in certain cases, may be of metal, concrete, such as reinforced concrete and the like. Suitable materials may also include composite materials, for example, fibre based composite materials.
While the ceilings, floors and walls to which the constructional elements may be secured, have been described as masonry walls, ceilings and floors, needless to say it will be readily apparent to those skilled in the art, that the constructional elements may be secured and used in conjunction with ceiling walls and floors of any other construction and/or material makeup.
The invention is not limited to the embodiments hereinbefore described, which may be varied in construction and detail.
