- the frame 12 is typically covered by floor sheeting (not shown) and is supported above a plurality of pier supports 10 positioned adjacent the connections between floor joist 14 and floor bearers 16 .
- Each floor pier support 10 is fixed at its base to a concrete footing 18 which is poured a predetermined depth within the ground to support the structure to be built above, whether it be a transportable house, a walkway, a patio, or the like.
- the position of each footing 18 is determined off-site, for example, using computer software which calculates the required spaced apart footing distances in accordance with the dimensions of the floor frame 12 which, in the embodiment shown, is also assembled off-site.
- each C-section member comprises a central web 20 and a pair of flanges 22 extending outwardly therefrom.
- Each flange 22 terminates with a flange return 24 .
- the floor joists 14 which comprise two opposed C-section members joined along their central webs 22 , are adapted to be inserted into the bearer 16 as shown in the enlarged view of FIG. 1 , and the flange return 24 of the bearer 16 is removed at these parts of the bearer in order to enable receipt of the joist 14 .
- the ends of the central webs 20 of each C-section member in joist 14 is folded over at approximately 90 degrees in order to form an end portion 26 , forming a box-shape at the end of the C-section member in joist 14 .
- the end portions 26 include a number of dimples 28 , each of which is centrally punched to receive a fixing member such as a rivet or screw (not shown).
- the web 20 of the bearer 16 is likewise dimpled or punched to assist in aligning the floor joist 14 relative to the bearer 16 during assembly, and additionally provide resistance against shearing when secured together via a rivet or the like.
- the joist 14 includes a slot 30 extending through the lower flange 22 of one of its C-section members, the purpose of which is described below.
- the floor frame 12 is adapted to be mounted a predetermined distance above the ground and is typically levelled using a laser level (not shown).
- the present invention provides for in-situ height adjustment of the floor frame using the adjustment means now described.
- the floor pier support 10 essentially comprises two parts, a hollow base member 32 of square cross-section having a C-section support bracket 34 fixed there above, and a frame connection member 36 .
- the hollow base member 32 could equally well have a different cross-sectional shape such as circular for example.
- the frame connection member 36 is shown as a separate component in FIGS. 4 a - 4 b, and the C-section support bracket 34 is shown as a separate component in FIGS. 5 a - 5 b.
- the hollow base member 32 includes a base plate (not shown) adapted to be bolted down to the footing 18 at a predetermined position also calculated by the computer software.
- the C-section support bracket 34 is fixed, preferably by a weld, to the top of the hollow base member 32 in a configuration whereby one of the C-section bracket parallel walls covers the open top of the base member 32 , and the opposed parallel wall extends a short distance there above.
- Each parallel wall includes a vertically extending aperture 38 and 40 which are co-axially aligned.
- the frame connection member 36 is in the shape of an inverted T-piece, that is, it includes an elongate bottom plate 42 and a transverse connection tab 44 extending upwardly from the bottom plate 42 .
- a threaded rod 46 extends downwardly from the opposite side of the plate 42 .
- the threaded rod 46 is firstly adapted to be inserted through the upper aperture 38 of the C-section support bracket 34 . Then, two levelling nuts 48 and 50 are screwed onto the threaded rod 46 , and the free end of the rod is then inserted into the second aperture 40 so that the nuts 48 and 50 are located between the two parallel walls of the C-section support bracket 34 .
- the free end of the threaded rod 46 therefore extends into the hollow base member 32 and the lower levelling nut 48 will typically bear against the lower wall of the bracket 34 due to the weight of the frame 12 thereabove. Although this will not always be the case, as is described further below.
- the joist 14 includes a slot 30 which extends through a lower flange 22 of one of its C-section members adjacent the central web 20 .
- the transverse connection tab 44 includes two vertically spaced apart apertures 52 and 54 . Therefore, once the connection tab 44 is inserted all the way into slot 30 , so that the bottom plate 42 abuts with the joist 14 , the spaced apart apertures 52 and 54 become co-axially aligned with respective spaced apart apertures 56 and 58 extending through the central webs 20 of the two opposed C-section members which form the joist 14 .
- a bolt 60 is adapted to extend through co-axially aligned apertures 52 and 56 , as is bolt 62 through apertures 54 and 58 . Both are secured by respective nuts 64 and 66 as known in the art. Once the nuts are tightened, the frame connection member 34 is thereby securely fixed to the joist 14 .
- connection means between the pier support and frame may well vary in accordance with the type of frame and other conditions.
- the frame connection member would be U-shaped in order to accommodate a typically square cross-sectioned timber beam joist.
- the frame connection means is not to be limited to only the tab-slot connection means embodied herein, but to any connection means of suitable strength.
- the tab-slot connection is used in preference to maintain consistency with the present inventor's unique roof and floor frame system which both incorporate a similar tab-slot connection between frame elements.
- Such a connection means is preferred because it maintains superior stiffness in steel frame joints.
- the hollow base member 32 and the frame connection member 36 are now both fixed which means that the height of the frame 12 is ready to be finely adjusted. This may be achieved using an appropriate level such as a laser level (not shown) as mentioned earlier, while manipulating the nuts 48 and 50 of each pier support 10 as described below.
- each component could be configured differently, for example, they could be oppositely threaded requiring unscrewing as opposed to screwing, and vice versa. Provided the means by which the height is adjusted is the same, then other components can equally well be used without deviating from the scope of the invention.
- the lower nut 48 in order to increase the height of the frame 12 the lower nut 48 is required to be screwed.
- the threaded rod 46 will be forced to move upwardly thereby raising the level of the frame 12 .
- the upper nut 50 will gradually move closer to the upper flange of the support bracket 34 , and so one needs to also unscrew the upper nut 50 in the meantime if/when required in order to maintain it in a floating state.
- the lower nut 48 In order to decrease the height of the frame 12 , the lower nut 48 needs to be unscrewed. The threaded rod 46 will be forced to move downwards thereby lowering the level of the frame 12 . During this process, the upper nut 50 will gradually move closer to nut 48 , and so one needs to also unscrew the upper nut 50 if/when required in order to maintain it in a floating state.
- the upper nut 50 can be tightened against the upper flange of the support bracket 34 (by unscrewing it), thereby locking the pier support in place. It is important during tightening of the upper nut 50 , that the lower nut 48 be maintained in the position it was moved to earlier using a level, so that the height of the frame is not affected during the locking process. Because of the weight of the frame bearing down on the nut 48 , it is likely that a spanner or other rotating tool will be required to rotate nut 48 , and also to maintain nut 48 in position during tightening of nut 50 .
- the frame may not cause nut 48 to bear against the lower flange of the C-section support bracket, for example, where the frame is lightweight, where the bearers/joists are not exactly straight, or where the supports at one end of the frame have been level adjusted and tightened but at the other end still requires adjustment.
- both the nut 48 and nut 50 may be floating.
- the pier support 10 of the present invention is also suitable in these circumstances.
- Raising of the frame is achieved using the same method described above whereby the lower nut 48 is screwed until it bears against the lower flange of the C-section support bracket 34 .
- the threaded rod 46 will eventually be forced to move upwardly thereby raising the level of the frame 12 , or at least reaching the level of the other pier supports which have been adjusted already. Tightening of nut 50 will then secure the pier support in place, as above.
- each base beam provides an extremely strong and robust support.
- the floor frame as a whole also has superior strength characteristics over existing systems. Once again, because the nuts are both exposed, they can be easily tightened at regular intervals post-construction, for maintenance purposes, or for height re-adjustment.
- the present invention is designed to be used in combination with unique pre-assembled floor frames which have been developed by the present inventor. However, it is to be understood that the present invention could equally well be used in combination with any type of floor frame, whether pre-assembled or assembled on-site.
- Existing or newly manufactured floor frames could be modified slightly in order to accommodate the connection tabs 44 associated with the frame connection members 36 . For example, slots could be machined into the frame at appropriate positions.
Abstract
The present invention relates to a floor pier support and, in particular, to a pier support which allows for in-situ height adjustment of a floor frame mounted thereabove. In particular, the pier support includes a base adapted to be fixed to said surface, a connection member including a first and a second attachment means, the first attachment means used to fix the connection member to a frame element, and the second attachment means being connectable to the base in a configuration which facilitates height adjustment of the frame relative to the base. The pier support of the present invention provides for a strong, robust support for floor frames and is advantageous in that the height of the frame can be easily adjusted at regular intervals post-construction, for maintenance purposes, or for height re-adjustment where for example the ground has subsided over time.
Description
- The present invention relates to a floor pier support and, in particular, to a pier support which allows for in-situ height adjustment of a floor frame.
- A typical pre-assembled floor frame is square or rectangular in shape and comprises a plurality of floor bearers and floor joists. Floor bearers are usually the outer load bearing elements of the frame and floor joists are the inner elements which extend between bearers and intersect one another to provide a support for floor sheeting there above. Such floor frames are typically used in the construction of transportable housing, decking, walkways, multi-level construction, patios and the like.
- Floor frames for such structures are required to be positioned a predetermined distance above the ground, or in the case of multi-level construction, above the ceiling frame of the room below. This is typically achieved using a plurality of pier supports positioned at various points beneath the frame to provide the required structural support thereto. Typically, the pier supports are positioned beneath bearer-joist connections and are thereby arranged in a matrix-type formation beneath the floor frame. Not every bearer-joist connection necessarily requires a pier support, this being job specific and is something an engineer will determine depending on structural requirements, wind speeds in the area, earthquake risk, etc.
- The current method of erecting these supports is to pour concrete footings or piers deep into the ground where each support is to be located. The location of each support is typically determined by computer software whereby a printout of the pier support locations is sent to a footing contractor. Being able to adjust the height of the supports is essential when erecting floor frames in that the level of the footings across the entire frame are often not uniform and hence if the supports were all the same height, the resultant floor frame would be uneven. Laser levels are typically used as an indicator when adjusting the height of the frame, and so it can be appreciated that height adjustment of only a few millimetres at particular sections of the frame is sometimes required.
- Existing pier supports known to the present inventor include a vertical base beam adapted to be fixed to each concrete footing, and a frame connection member to which the floor frame is fixed, the connection member being threadably connected to the base beam for height adjustment. Such systems are unsuitable because they do not allow for in-situ levelling of floor frames. In particular, levelling must be performed prior to the floor frame being fixed to the base frames, and the height of the frame may not be easily adjusted thereafter. There is therefore a need for supports which allow a floor frame to be erected with more speed and accuracy than hitherto known supports.
- Another important issue is the structural integrity of existing pier supports, particularly in rough wind conditions and earthquake prone areas. The strength of the support is dependant upon its design and construction, and the way in which it is connected to the frame. Existing supports known to the applicant do not have a strong and robust means of connection between the base beams and floor frame.
- The present inventor is the owner of various patents and patent applications directed to the manufacture of floor frames, in particular, pre-assembled steel floor frames which include unique connection means in the form of tab-slot connections. Connection tabs are associated with one frame member and are insertable into slots associated with another frame member for connection thereto. There is therefore also a need for a floor pier support which is suitable for use in association with existing floor frame systems such as this one, but which is not limited to such systems.
- It is therefore an object of the present invention to overcome at least some of the aforementioned problems or to provide the public with a useful alternative.
- It is a further object of the present invention to provide floor pier supports which provide for more simplified and accurate erection of a floor frame there above, as well as a more strong and robust connection between support and frame.
- It is a still further object of the invention to provide a floor pier support which allows for the height of the associated floor frame to be easily raised or lowered in-situ. For example, in a situation where the ground has subsided in one area of a floor frame over time, the relevant pier support can be adjusted accordingly without having to remove the entire frame, or parts thereof.
- Therefore in one form of the invention there is proposed a pier support for maintaining a frame element above a surface, said pier support including:
- a base adapted to be fixed to said surface;
- a connection member including a first and a second attachment means, said first attachment means used to fix the connection member to a frame element, and said second attachment means being connectable to the base in a configuration which facilitates height adjustment of the frame relative to the base.
- Preferably the pier support includes a means of locking the frame element at a desired height.
- Preferably said base includes two parallel surfaces having co-axially aligned apertures, said second attachment means of the connection member including a threaded shaft insertable through said co-axial apertures for engagement with two correspondingly threaded nuts located between the two parallel surfaces.
- In preference the first nut is used to adjust the height of the connection member and the second nut is used to lock the connection member at a desired height relative to said base.
- Preferably the first nut is adapted to bear against a first of said parallel surfaces, said first nut raising the height of the connection member by way of rotation in a first direction relative to the threaded shaft, and lowering the height of the connection member by way of rotation in the opposite direction.
- Preferably said first nut bears against said first surface by the weight of the frame element. The weight of the frame typically bears down against the connection member causing the lower levelling nut to bear against the first surface at all times. Preferably through adjustment of the levelling nut relative to the threaded rod, the level of the connection member and hence the frame element can be raised or lowered.
- Alternatively said first nut bears against said first surface by way of manual adjustment towards said first surface. For example, there may be circumstances where the frame does not cause the lower levelling nut to bear against the first surface.
- In preference the second nut is adapted to be tightened against the second of said parallel surfaces once the desired height is achieved, to thereby lock the connection member at said desired height.
- Preferably said base is in the form of an upright hollow beam and said surface to which the base is fixed is a concrete footing.
- Preferably said first and second parallel surfaces form part of a C-section bracket mounted above said upright beam in a configuration whereby said first and second surfaces extend substantially horizontally.
- In preference said frame element is a joist comprising two C-section members each having a central web and a pair of flanges extending outwardly therefrom, said C-section members being joined along their central webs to form said joist.
- Preferably said first attachment means of the connection member is in the form of a T-piece having a base plate and an upright tab.
- Preferably each joist includes at least one slot located in a lower flange of a C-section member adjacent the central web, said slot shaped to receive the connection member upright tab.
- Preferably after the upright tab is inserted into said slot, it is adapted to be fixed to the central webs of the two adjoining C-section members forming the joist.
- In preference said joist forms part of a floor frame having a plurality of connecting joists and bearers.
- In preference each slot is positioned proximate the joist-bearer connection.
- In a further form of the invention there is proposed a pier support for supporting at least one frame element of a horizontal frame, said pier support including:
- a base;
- an elongate support member extending substantially vertically from the base and having a remote end opposed to the base with a cavity;

Although the description includes exemplary embodiments, other embodiments are possible, and changes may be made to the embodiments described without departing from the spirit and scope of the invention. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same and like parts.
- The present invention relates to a
floor pier support 10 andfloor frame 12 incorporating such floor pier supports, as shown inFIGS. 1-3 . InFIG. 1 , apre-assembled floor frame 12 is shown which comprisesfloor joists 14 andfloor bearers 16, each of which is formed from C-section structural members rolled from light-gauge strip steel. Theframe 12 is typically covered by floor sheeting (not shown) and is supported above a plurality of pier supports 10 positioned adjacent the connections betweenfloor joist 14 andfloor bearers 16. - It is to be understood that the present invention is not to be limited to use in supporting floor frames only but may equally well be used in the support of any structure which may require in-situ height adjustment.
- Each
floor pier support 10 is fixed at its base to aconcrete footing 18 which is poured a predetermined depth within the ground to support the structure to be built above, whether it be a transportable house, a walkway, a patio, or the like. The position of eachfooting 18 is determined off-site, for example, using computer software which calculates the required spaced apart footing distances in accordance with the dimensions of thefloor frame 12 which, in the embodiment shown, is also assembled off-site. - Turning now to the
floor frame 12 in more detail, the floor joists 14 andfloor bearers 16 are each made up of C-section members and for the purpose of brevity, each similar feature of thejoist 14 andbearer 16 will be referenced using like numbers. Each C-section member comprises acentral web 20 and a pair offlanges 22 extending outwardly therefrom. Eachflange 22 terminates with aflange return 24. The floor joists 14, which comprise two opposed C-section members joined along theircentral webs 22, are adapted to be inserted into thebearer 16 as shown in the enlarged view ofFIG. 1 , and theflange return 24 of thebearer 16 is removed at these parts of the bearer in order to enable receipt of thejoist 14. - The ends of the
central webs 20 of each C-section member injoist 14 is folded over at approximately 90 degrees in order to form anend portion 26, forming a box-shape at the end of the C-section member injoist 14. Theend portions 26 include a number ofdimples 28, each of which is centrally punched to receive a fixing member such as a rivet or screw (not shown). Theweb 20 of thebearer 16 is likewise dimpled or punched to assist in aligning thefloor joist 14 relative to thebearer 16 during assembly, and additionally provide resistance against shearing when secured together via a rivet or the like. Thejoist 14 includes aslot 30 extending through thelower flange 22 of one of its C-section members, the purpose of which is described below. - As mentioned in the preamble of the invention, the
floor frame 12 is adapted to be mounted a predetermined distance above the ground and is typically levelled using a laser level (not shown). The present invention provides for in-situ height adjustment of the floor frame using the adjustment means now described. - The
floor pier support 10 essentially comprises two parts, ahollow base member 32 of square cross-section having a C-section support bracket 34 fixed there above, and aframe connection member 36. Thehollow base member 32 could equally well have a different cross-sectional shape such as circular for example. Theframe connection member 36 is shown as a separate component inFIGS. 4 a-4 b, and the C-section support bracket 34 is shown as a separate component inFIGS. 5 a-5 b. - The
hollow base member 32 includes a base plate (not shown) adapted to be bolted down to thefooting 18 at a predetermined position also calculated by the computer software. The C-section support bracket 34 is fixed, preferably by a weld, to the top of thehollow base member 32 in a configuration whereby one of the C-section bracket parallel walls covers the open top of thebase member 32, and the opposed parallel wall extends a short distance there above. Each parallel wall includes a vertically extendingaperture - The
frame connection member 36 is in the shape of an inverted T-piece, that is, it includes anelongate bottom plate 42 and atransverse connection tab 44 extending upwardly from thebottom plate 42. A threadedrod 46 extends downwardly from the opposite side of theplate 42. - During assembly, the threaded
rod 46 is firstly adapted to be inserted through theupper aperture 38 of the C-section support bracket 34. Then, two levellingnuts rod 46, and the free end of the rod is then inserted into thesecond aperture 40 so that the nuts 48 and 50 are located between the two parallel walls of the C-section support bracket 34. The free end of the threadedrod 46 therefore extends into thehollow base member 32 and thelower levelling nut 48 will typically bear against the lower wall of thebracket 34 due to the weight of theframe 12 thereabove. Although this will not always be the case, as is described further below. - As mentioned above, the
joist 14 includes aslot 30 which extends through alower flange 22 of one of its C-section members adjacent thecentral web 20. Thetransverse connection tab 44 includes two vertically spaced apart apertures 52 and 54. Therefore, once theconnection tab 44 is inserted all the way intoslot 30, so that thebottom plate 42 abuts with thejoist 14, the spaced apart apertures 52 and 54 become co-axially aligned with respective spaced apart apertures 56 and 58 extending through thecentral webs 20 of the two opposed C-section members which form thejoist 14. Abolt 60 is adapted to extend through co-axiallyaligned apertures bolt 62 throughapertures respective nuts frame connection member 34 is thereby securely fixed to thejoist 14. - It is to be understood that the connection means between the pier support and frame may well vary in accordance with the type of frame and other conditions. For example, in the case of timber frames having timber joists, the frame connection member would be U-shaped in order to accommodate a typically square cross-sectioned timber beam joist.
- Also, in the case of steel frames, the frame connection means is not to be limited to only the tab-slot connection means embodied herein, but to any connection means of suitable strength. The tab-slot connection is used in preference to maintain consistency with the present inventor's unique roof and floor frame system which both incorporate a similar tab-slot connection between frame elements. Such a connection means is preferred because it maintains superior stiffness in steel frame joints.
- The
hollow base member 32 and theframe connection member 36 are now both fixed which means that the height of theframe 12 is ready to be finely adjusted. This may be achieved using an appropriate level such as a laser level (not shown) as mentioned earlier, while manipulating the nuts 48 and 50 of eachpier support 10 as described below. - It is to be understood that when the following description refers to screwing of the nuts, this is intended to mean rotation thereof in a clockwise motion when viewing the apparatus from above, and likewise, unscrewing of the nuts is intended to mean rotation thereof in an anticlockwise motion when viewing the apparatus from above.
- It is to be further understood that each component could be configured differently, for example, they could be oppositely threaded requiring unscrewing as opposed to screwing, and vice versa. Provided the means by which the height is adjusted is the same, then other components can equally well be used without deviating from the scope of the invention.
- In the embodiment shown, in order to increase the height of the
frame 12 thelower nut 48 is required to be screwed. The threadedrod 46 will be forced to move upwardly thereby raising the level of theframe 12. Of course, during this process, theupper nut 50 will gradually move closer to the upper flange of thesupport bracket 34, and so one needs to also unscrew theupper nut 50 in the meantime if/when required in order to maintain it in a floating state. - In order to decrease the height of the
frame 12, thelower nut 48 needs to be unscrewed. The threadedrod 46 will be forced to move downwards thereby lowering the level of theframe 12. During this process, theupper nut 50 will gradually move closer tonut 48, and so one needs to also unscrew theupper nut 50 if/when required in order to maintain it in a floating state. - Once a desired level is reached through adjustment of the
lower nut 48, theupper nut 50 can be tightened against the upper flange of the support bracket 34 (by unscrewing it), thereby locking the pier support in place. It is important during tightening of theupper nut 50, that thelower nut 48 be maintained in the position it was moved to earlier using a level, so that the height of the frame is not affected during the locking process. Because of the weight of the frame bearing down on thenut 48, it is likely that a spanner or other rotating tool will be required to rotatenut 48, and also to maintainnut 48 in position during tightening ofnut 50. - There may be circumstances in which the frame may not cause
nut 48 to bear against the lower flange of the C-section support bracket, for example, where the frame is lightweight, where the bearers/joists are not exactly straight, or where the supports at one end of the frame have been level adjusted and tightened but at the other end still requires adjustment. In such circumstances, both thenut 48 andnut 50 may be floating. Thepier support 10 of the present invention is also suitable in these circumstances. - Raising of the frame is achieved using the same method described above whereby the
lower nut 48 is screwed until it bears against the lower flange of the C-section support bracket 34. The threadedrod 46 will eventually be forced to move upwardly thereby raising the level of theframe 12, or at least reaching the level of the other pier supports which have been adjusted already. Tightening ofnut 50 will then secure the pier support in place, as above. - However, lowering the frame is achieved slightly differently because the weight of the frame can no longer be relied upon. Because the
lower nut 48 does not bear down against the lower flange of thesupport bracket 34, unscrewing of thenut 48 alone will not cause the threaded rod to move downwardly. Therefore, alternatively, theupper nut 50 needs to be unscrewed so that it bears against the upper flange of the C-section support bracket 34. The threadedrod 46 will eventually be forced to move downwardly thereby lowering the level of theframe 12.Nut 48 can then be tightened against the lower flange (by unscrewing it) in order to secure the support in the desired position. Effectively,nut 50 becomes the adjusting nut, andnut 48 becomes the locking nut. - The skilled addressee should now realise the benefits provided by the present invention. Various adjustable pier support systems exist, however, none that are known to the present inventor can be assembled as quickly and efficiently as the
pier support 10 of the present invention. One of the improvements resides in the use of the C-section support bracket 34 which exposes twonuts frame 12 at a desired level. This configuration enables height adjustment without the need for moving any of the supporting structures such as the base beam or the frame connection member, allowing these components to be assembled prior to adjusting the height of the floor. Theentire floor frame 12 can therefore be levelled in-situ. - In using the
floor pier support 10 of the present invention, the strength and integrity of the support provided to theframe 12 is also not compromised. Once the desired level is achieved and the bolts secured, each base beam provides an extremely strong and robust support. When using the tab-slot frame connection embodied herein, the floor frame as a whole also has superior strength characteristics over existing systems. Once again, because the nuts are both exposed, they can be easily tightened at regular intervals post-construction, for maintenance purposes, or for height re-adjustment. - The present invention is designed to be used in combination with unique pre-assembled floor frames which have been developed by the present inventor. However, it is to be understood that the present invention could equally well be used in combination with any type of floor frame, whether pre-assembled or assembled on-site. Existing or newly manufactured floor frames could be modified slightly in order to accommodate the
connection tabs 44 associated with theframe connection members 36. For example, slots could be machined into the frame at appropriate positions. - Further advantages and improvements may very well be made to the present invention without deviating from its scope. Although the invention has been shown and described in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope and spirit of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices and apparatus.
- In any claims that follow and in the summary of the invention, except where the context requires otherwise due to express language or necessary implication, the word “comprising” is used in the sense of “including”, i.e. the features specified may be associated with further features in various embodiments of the invention.
