Abstract
An anchorage joint (20) to secure a timber frame of a building to a concrete foundation (15) comprises a bar (21) adapted to have one end (22) embedded within the foundation (15). A sleeve (25) encompasses the exposed end of the bar (21), the sleeve being adapted to be fixed to a timber member (13) of a timber frame and engaged by the bar (21) to thereby secure the member (13), and therefore the frame, to the foundation (15).
Description
- The present invention relates to the manufacture and erection of prefabricated frames for buildings, and more particularly to timber frames of such buildings and attachment thereof to foundations.
- It is a disadvantage of known methods of anchoring timber frames to foundations, that the frames require a high degree of precision in manufacture since the position of the anchorage bolts may vary as much as ± 1 mm.
- It is an object of the present invention to overcome or substantially ameliorate the above disadvantages.
- There is disclosed herein an anchorage joint to secure a timber frame of a building to concrete foundations, said joint comprising: a bar adapted to have one end portion securely embedded within the foundation so as to extend generally vertically therefrom, a sleeve to encompass the exposed portion of said bar and adapted to abut said foundation so as to extend generally vertically therefrom, said sleeve defining a hollow having a transverse cross-section greater than the transverse cross-section of said rod to thereby allow transverse relative movement between the rod and sleeve, tensioning means coupling an upper portion of said rod and an upper portion of said sleeve, said means being adapted to engage said rod so as to tension same while applying the resulting reaction force to said sleeve to thereby secure the sleeve to the foundation, and frame engaging means fixed to said sleeve to which said frame is to be fixed.
- A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings, wherein:
- Figure 1 schematically depicts in perspective view a house frame and foundation attached thereto;
- Figure 2 is a schematic part sectioned elevation of an anchorage joint to secure the frame of Figure 1 to the foundation of Figure 1;
- Figure 3 is a side elevation in part section of a further anchorage joint to be used to secure the frame of Figure 1 to the foundation of Figure 1.
- Figure 4 is a plan view of the top portion of the anchorage bolt of Figure 3;
- Figure 5 is a plan view of the lower portion of the anchorage bolt of Figure 3;
- Figure 6 is a side elevation of the sleeve and timber engaging portions of the anchorage joint of Figure 3;
- Figure 7 is a plan view of the sleeve of Figure 6 sectioned along the line A-A thereof;
- Figures 8 and 10 are sectioned side elevations of a further anchorage joint to be used to secure the frame of Figure 1 to the foundation of Figure 1; and
- Figures 9 and 11 are plan views of the anchorage joint of Figures 8 and 10 sectioned along the lines A-A thereof.
- In Figure 1 there is schematically depicted a
timber frame 10 having a plurality of generally vertical timber members 11 joined by a plurality ofhorizontal members 14. Theframe 10 is secured to concrete orbrick foundations 15 by way ofanchorage joints 16. - Firstly with particular reference to Figure 2, there is schematically depicted an
anchorage joint 20 adapted to engage atimber member 13 to secure it to thefoundation 15. Theanchorage joint 20 includes a rod 21 which is bent so as to have a generally L-shapedlower section 22 which is securely embedded within thefoundation 15. The rod 21 extends upwardly from thefoundation 15 and includes a threadedportion 23 which is adapted to engage anut 24. Thejoint 20 further includes asleeve 25 which encompasses the exposed portion of the rod 21 and abuts thefoundation 15 by means of aflange 26. Connecting thesleeve 25 and rod 21 is atransverse member 28 which transfers tension forces in the rod 21 to thesleeve 25 so as to secure thesleeve 25 to thefoundation 15. - Fixed to the
sleeve 25 is thetimber member 13 by means of abolt 27. Thebolt 27 extends through apassage 29 formed in themember 13 andopenings 30 formed in thesleeve 25. It should be appreciated that the rod 21 is not straight but is bent so as to be located spaced from the longitudinal axis of thesleeve 25 to allow thebolt 27 to pass through the centre of thesleeve 25. - Now with reference to Figures 3 to 5 wherein there is depicted an
anchorage joint 40 which secures the vertical timber member andhorizontal timber members 14 to thefoundation 15. Theanchorage joint 40 includes arod 41 which as previously, is secured within theconcrete foundation 15, asleeve 42 which is engaged by atransverse member 43 which transfers tension forces in thebolt 41 to thesleeve 42 so as to secure thesleeve 42 to thefoundation 15. - The
rod 41 is provided with an upper threadedpart 44 which is engaged by anut 45. As described previously thejoint 40 is provided withpassages 46 which allow a bolt 47 to pass through thesleeve 42 andpassage 48 formed in themember 13 to secure themember 13 to thesleeve 42. The lower portion of theanchorage joint 40 includes a plurality offins 49 which are located withinslots 50 formed in thetimber members 14. Thefins 49 are provided withholes 51 which allow abolt 52 to pass therethrough to thereby secure themembers 14 to theanchorage joint 40 by way of apassage 53 formed in thetimber members 14. - In Figures 6 to 11 there are depicted alternative forms of the sleeve which forms part of the anchorage joints, which various forms enable the
timber members foundations 15. As can be seen from Figures 6 and 7, the sleeve depicted therein enables fourhorizontal members 14 together with avertical member 13 to be secured to thefoundation 15. On the other end, the sleeve of Figures 8 and 9 is adapted to secure twohorizontal members 14 and avertical member 13 to thefoundation 15 while lastly, in Figures 10 and 11, the sleeve depicted therein enables threehorizontal members 14 and avertical member 13 to be secured to thefoundation member 15.
