Description
FLOORING SYSTEM WITH CONCRETE SLABS SUPPORTED BY TRUSSES
FIELD OF INVENTION
The present invention relates to improvements to flooring, in particular but not exclusively to methods and systems involving said improvements.
BACKGROUND ART KNOWN TO THE APPLICANT
Conventional flooring systems for the ground floor of modern domestic properties have tended to be made of wood or concrete. Both possess excellent thermal properties but the sound proofing of concrete is far superior to that of conventional wooden floor boards. As it is not practical or indeed even cost effective to construct the second or subsequent floor of domestic properties with concrete, these subsequent floors are usually made from wooden floorboards.
The lack of sound proofing afforded by such flooring materials means that there will always be a tendency to hear footsteps of an individual walking across flooring that is anything other than the ground floor (if the ground floor is made of concrete).
Attempts to solve this problem have tended to involve the soundproofing of the gap generated by a ceiling of for example, a ground floor of the housing and the flooring of the next level as they tend to separated by wooden trusses.
This has been successful to some degree and the design of such trusses enable conduits or wiring between the floors to be laid.
In respect of industrial properties, the situation is somewhat different in so far as the equivalent of concrete floor boards (elongate slabs of concrete) tend to be used which does solve the problem of unwanted noise however, in the case of industrial properties the trusses themselves are either concrete or steel or a combination of both and as such are able to support concrete flooring..
It is therefore an object of the present invention to provide an improved floor or flooring system for properties or indeed an improved method of construction of such properties which will attempt to alleviate the foregoing disadvantages or which will at least provide the public with a useful choice.
Furthermore, It will become apparent that whilst the present invention is set out in the form of several different aspects, each of these separate aspects are indeed so linked as to form part of the same inventive concept.
STATEMENTS OF THE INVENTION
According to a first aspect of the present invention there is provided a flooring system comprising a structure capable of receiving a floor, sufficient truss support members capable of receiving a plurality of reinforced wooden trusses once the truss support members form part of the structure, a plurality of such reinforced wooden trasses adapted to receive a floor once these trusses are fitted to the truss support members and an entire floor made up of preformed concrete slabs.
Such a system tends to alleviate the problem of noise as the concrete does not tend to allow sound to travel through it.
Of course, there are several ways in which a wooden trass may be reinforced, for example they could be reinforced through the use of fitted reinforcing members made from plastics material or concrete, however, preferably, the reinforced wooden trasses are fitted with metal reinforcing members.
Such metal reinforcing members can be substantially the pure metal or the metal alloy or plastics coated metal and in addition, nay be selected from the group comprising steel, iron, copper or powder coated steel.
The metal reinforcing members may be in the form of webs (such as those used to form the trass sold under the Trade Mark "Pryda Span"™) alternatively, the metal reinforcing member is in the form of a "nail plate" (such as those used to form the trass sold under the Trade Mark "Pryda longreach"™).
More preferably, the trass used in the flooring system is a "Pryda longreach"™ trass.
Ideally, each concrete slab is pre-stressed and although both the length and width of the slabs may vary, preferably, the width of each slab remains substantially constant whilst the length of each slab is variable.
Each truss support member could either be the top face of a wall of the structure, or some form of beam (e.g. an "I" beam) adapted to fit to the top face of a wall of the structure. However, preferably, each truss support member is an item adapted to be fitted to an internal side face of a wall of the structure. Such a member could be wooden, metallic or a combination of both.
The invention includes within its scope a flooring system substantially as herein described with reference to any appropriate selection or combination of the accompanying drawings.
According to a second aspect of the present invention there is provided a method of construction comprising the steps of:
Providing a structure with one or more truss support members;
Fitting a plurality of reinforced wooden trusses to a number of the truss support members;
Fitting an entire floor made up of pre-formed concrete slabs to or to form part of the structure.
The invention includes within its scope, a method substantially as herein described with reference to any appropriate selection or combination of the accompanying drawings.
According to a third aspect of the present invention, there is provided a preformed, pre- stressed concrete 'floorboard' substantially 1200mm wide, for use with a system or method as specified herein.
Use of a preformed, pre-stressed concrete 'floorboard' with the system or method described herein.
The invention further includes within its scope a partially completed or completed structure incorporating one or more trusses and concrete 'floorboards' of the type described herein.
BRIEF DESCRIPTION OF THE DRAWINGS
Preferred embodiments of the present invention will now be more particularly described by way of example only, with reference to the accompanying drawings in which:
Figure 1 is a perspective view of a part completed structure prior to a non 'ground floor', floor being laid highlighting inter alia a plurality of all wooden trusses and truss support members typical of prior art flooring systems.
Figure2 is a perspective view of an alternative part completed structure incorporating a concrete 'floorboard' of the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 shows a part completed multi-storey domestic New Zealand property or structure that is generally referenced 1.
The structure 1 is formed in part, from walls, the skeletal framework of which is formed from planks of timber (2,3), the vertical timbers 3 linked by horizontal timbers 2. The uppermost timbers 2 of any given skeletal framework act as supports for the all wooden trusses 4 that are so sized and shaped as to overlie opposing truss supports 2 in a substantially flush manner. Elongate wooden floorboards are then laid across the trusses such that the longitudinal axis of the floorboards are substantially orthogonal to the longitudinal axis of the trusses.
Turning now to figure 2, this shows a part completed multi-storey domestic New Zealand property or structure of the present invention that is generally referenced 10. The structure 10 is provided with a wall 3 of similar construction to that shown in figure 1 and the internal face of the wall 3 has been fitted with an elongate metal truss support member 2. The support 2 is set below but is substantially parallel with the top of the wall 3 and is so located on the wall 3 that when reinforced wooden trusses (4,6) are fitted to the truss support 2, the tops of the trusses (4,6) lie substantially flush with the top of the wall 3.
The trusses (4,6) are typical "Pryda span"™ trusses i.e. wooden frames 4 fitted with reinforcing "V" shaped metal webs 6 on opposing sides of the wooden frame 4.
A pre-stressed, preformed concrete slab 5 that is 1200mm wide overlies the trusses (4,6) (in a similar manner to the wooden floorboards of figure 1) and the top of the wall 3.
In use, a system comprising truss supports 2, reinforced trusses (4,6) and pre-stressed, preformed concrete slabs 5 (which may be supplied to a construction site when required) is supplied to a construction site.
Once the ground floor and walls 3 of the structure 10 are erected, the truss supports 2 are fitted to the internal walls 3 of the structure 10 and then a plurality of the reinforced wooden trusses (4,6) are fitted to a number of the truss support members 2. Finally, an entire floor made up of pre- formed pre-stressed concrete slabs 5 are fitted to the trusses (4,6) and in this particular instance (as the walls 3 are wooden), to the tops of the walls 3 as well.
Once a floor of the type just described has been laid, the next tier of the structure 10 can be started, allowing for further floors using the above system and method to be applied once more.
In alternative embodiments not illustrated, if the walls are made from concrete, it may not be necessary to overlie the slabs 5 across the tops of the wall.
