Description
WALL TYING
This invention relates to a method and apparatus for wall tying.
A known method of building a new wall of brick or building blocks onto an existing wall, e.g. at right-angles to the existing wall, is to attach an elongate member immovably and in upright attitude to the first wall and provide a plurality of tying members between courses of the new wall and connected to the upright elongate member. Two types of wall tying apparatus for use in this method are known.
In one, the elongate member and the plurality of tying members are supplied as separate elements for interconnection at the building site, such interconnection permitting vertical relative movement between the tying members and the vertically immovable elongate member attached to the existing wall whereby vertical movement of the new wall relative to the existing wall (e.g. due to differential settlement) might be accomodated. Examples of such wall tying apparatus are disclosed in UK Patent
Publications Nos. 2162216 and 2162217.
In the other type of tying apparatus, the elongate member and the plurality of tying members are formed integral with one another, the tying members being deformable to accomodate vertical movement of the new wall relative to the existing wall (e.g. due to differential settlement).
Examples of this type of wall tying apparatus are disclosed in UK Patent Publications Nos. 2014640 and 2147023.
It is considered desirable to provide wall tying apparatus whereby a substantially increased degree of relative movement between new and existing walls can be safely permitted and/or accomodated.
According to one aspect of this invention there is provided wall tying apparatus comprising an elongate member, means for attaching the elongate member in upright attitude to a first wall such that, when attached and in use, it can move relative to the first wall in a direction longitudinally of the elongate member, and tying means to extend in use in between courses of bricks or building blocks of a second wall and to interconnect the second wall and said elongate member.
Advantageously said means for attaching the elongate member in upright attitude to the first wall comprises elongate apertures directed longitudinally of the elongate member.
Preferably said tying means and/or its interconnection between the second wall and elongate member is such as to permit in use relative vertical movement between the second wall and the elongate member. When in use and effecting said interconnection the tying members may be separate from the elongate member, or alternatively may be integral with the elongate member.
In one preferred embodiment the tying apparatus comprises an elongate member in the form of a metal stamping or pressing to be in use attached in upright attitude to a first wall, and a plurality of tying members each attached to the elongate member, for supply therewith, by means of a readily frangible element enabling the tying member to be readily separable from the elongate member by breaking of said frangible element, the elongate member being formed with retention means for the tying members when in their separated, in use, condition to extend in between courses of bricks or building blocks of a second wall.
In another preferred embodiment the tying apparatus comprises an elongate member in the form of a metal stamping or pressing to be in use attached in upright attitude to a first wall, and a plurality of wire tying members of generally U-shape in plan view and which are separate from the elongate member. In this embodiment the elongate member is formed with retention means comprising two columns of pressed-out straps providing vertical sockets that are in use slidably to receive vertically directed portions depending (or upstanding) from the limbs of the generally Ushaped tying members. Said limbs may be of linear form or of sinuous form.
According to another aspect of this invention there is provided wall tying apparatus comprising an elongate member, means for attaching the elongate member in upright attitude to a first wall, and tying means to extend in use in between courses of bricks or building blocks of a second wall and to interconnect the second wall and said elongate member, wherein said elongate attachment member comprises stamped out portions defining a plurality of pairs of sockets, the two sockets of each pair being spaced apart transversely of the attachment member and being directed longitudinally of the attachment member, and wherein the tying means comprises at least one wire tie having two main limb portions that are in use to extend in use horizontally as aforesaid, said main limb portions being interconnected at one end and being formed at the other end with engagement portions in use to be slidably inserted in, and guided by, a said pair of vertically directed sockets.

The wall tying apparatus 10 illustrated in Figs 1-5 comprises an elongate member of stainless or galvanised steel formed as a unitary item by one or more metal stamping or pressing operations. The unitary member 10 comprises a generally plate-like portion 12 having its two opposite, longitudinal edges 14 folded backwardly to provide edge reinforcement or rigidity. Tie retention means in the form of transverse straps 15 stand proud forwardly of the front face of the plate-like portion 12. Tie members 16, which in use of the apparatus are to be retained by the straps 15, are initially provided by stamping of the material of the plate-like portion.12 between successive straps 15. Each of the tie members 16 is of generally rectangular outline but this outline 17 is stamped with at least one discontinuation (i.e. is provided with an incomplete perimeter). Each tie member 16 thereby remains integrally connected and attached to the main body of the plate-like portion 12 by at least one short readily frangible element 18, the tie member being disposed in or overlying the aperture 19 provided in plate-like portion 12 by its defining outline 17.
Conveniently, as shown, just one outline discontinuation is provided, i.e. just a single frangible element 18 is provided. Preferably this is located at, or in the vicinity of, a corner of the generally rectangular outline. This corner location for the frangible element 18 tends to provide for twisting of the tie member 16 as it is pushed outwards of the aperture 19, such twisting facilitating the intended fracture of the frangible element 18 immediately prior to use.
Each of the tie members 16 is stamped to be formed with a transverse crease or fold-line 20 and is pre-bent (see Fig 3) along that crease or fold-line to facilitate further bending of the tie member into the intended final shape it is to adopt in use as a separated and individual tying member 16. This partial pre-forming provides the tie member 16 with a root portion 21 of generally square-shaped outline and an elongate tying portion 22 of generally rectangular outline for disposition in the mortar or cement between two super imposed rows of building blocks or bricks of the new wall. Root portion 21 is formed with one or more (preferably three) longitudinally extending, parallel ribs 31, and the tying portion 22 is formed with one or more (preferably three) longitudinally extending, parallel ribs 32, the ribs 31,32 being to provide rigidity and/or reinforcement.In the tying portion 22, the middle one of the three ribs 32 is substantially shorter in length and the remaining space between the two outer and longer ribs is occupied by a series of skirted holes 24 (Fig 5) or flat-bottomed depressions 34 (Fig 6) which, in each case, are to provide a good key between the tying portion 22 and the mortar or cement of the new wall into which the tying portion 22 is embedded.
Preferably, as shown, the stamping operation is such that each tying portion 22 extends progressively forwardly of the plate-like portion 12 as it approaches the root portion 21, and the latter extends rearwardly of the plate-like portion 12 and through the aperture 19 so that the bent-over free end 23 of the root portion 21 is disposed to the rear of the plate-like portion 12. Alternatively, the stamping operation can provide for the tying portion 22 to extend rearwardly as it apprdaches root portion 21, and for the latter to extend forwardly of plate-like portion 12 and project through aperture 19.
The elongate plate-like portion 12 is provided with a plurality of elongate fixing holes 25 each extending longitudinally of the elongate member along its centre line.
These elongate fixing holes 25 in use permit relative movement between member 10 and the existing wall, e.g. due to the forces arising from severe differential settlement between the existing and the new walls. A row of three conical depressions 26 is formed alongside and adjacent to each side of each hole 25. In use, the conical depressions 26 space the plate from the first (i.e. the existing) wall and resist deformation of the tying apparatus 10 due to over-tightening of the fixing screws or bolts inserted through holes 25 to fasten the plate-like portion 12 to the first wall. A plurality, e.g. four, similar conical depressions 27 are provided, for similar purposes, adjacent each of the straps 15. The plate-like portion is also provided with two reinforcing ribs 28 extending longitudinally adjacent the backwardly folded edges 14.
The unitary item 10 illustrated can be readily manufactured for supply as a single complete article for carriage, as a single complete article, to the site of intended use and for storage, as a single complete article, on the site until actual use is required. At that juncture, the tying members 16 can be broken out from the plate-like portion 12. This can be performed wholly manually and prior to fixing the plate-like portion to the existing (first) wall onto which the second (new) wall is to be built. Alternatively, the act of fixing the plate-like portion 12 to the first wall automatically pushes the tying members forwardly and outwards of the apertures 19 simultaneously causing them to twist about the corner elements 18 by which they are held captive integrally with the plate-like portion 12.
Ultimately, the elements 18 are fractured, either by the automatically induced twisting action alone or with the assistance of a supplementary manual operation, so that the tying members become free of the plate-like portion.
For use, the elongate member 10 is fixedly attached, in upright attitude, to the existing (first) wall at the location where the new (second) wall is to be built to extend at right-angles to the existing (first) wall. The mode of attachment is by screws or coach-bolts through the elongate holes 25, preferably adjacent the lower ends of these holes.
As the new (second) wall is built up with the end bricks or building blocks of the new wall abutting endwise onto the upright elongate member 10, a tying member 16 can be attached by its root portion 21 to the member's plate-like portion 12 and have its tying portion 22 inserted into the mortar or cement between two courses of the new (second) wall. To achieve this, the tying member's root portion 21 is vertically inserted slidingly - downwards or upwards behind a strap 15 (i.e. between the strap and the adjacent plate-like portion 12).Following insertion, the tying portion 22 is manually bent further about the crease or fold line 20 until it extends substantially horizontally so as to be embedded into the mortar or cement between the end bricks or building blocks of two superimposed courses of the new wall. -It will be appreciated that reaction to such bending is provided by engagement of the root portion 21 and both the strap 15 and the plate-like portion 12 (disposed both above and below that strap), such reaction forces being readily accomodated by the reinforcement provided by depressions 27 adjacent each strap 15.
It will also be appreciated that the bent lateral ends of the straps 15 (which connect the straps to the main body of the plate-like portion 12) provide in use for vertical sliding motion of the tying members 16 relative to the plate-like portion 12, and for such motion to be guided and laterally confined by these bent lateral ends of the straps.
Such motion can, for example, arise due to differential settlement of the first and second walls. Moreover, the elongate holes 25, being directed longitudinally of member 10, in use permit vertical relative sliding between member 10 and the existing wall to which it is attached. Thus relative vertical movement can be permitted between the new wall and the plate-like portion 12 and also between the plate-like portion 12 and the existing wall.In practice, it is expected that such relative vertical movement of the two walls will be initially accomodated by relative sliding movement between the tying members and the upright attachment member, and that only after the maximum possible sliding displacement has been taken up - when the tying members abut the top of, and yet remain retained by, the straps, that further relative vertical movement of the two walls can be accomodated by relative sliding movement between the elongate attachment member and the screws or bolts that attach it to the first wall. Accordingly, it is considered that the tying apparatus 10 as a whole can permit severe differential settlement between the new and the existing wall to be accomodated with little or no detriment to the restraint provided by the tying apparatus against relative horizontal movement of the two walls. Nevertheless, prior to (or in the absence of) such differential settlement, any mortar or cement from the new (second) wall which, during construction, passes through and behind the plate-like portion may potentially enhance bonding between the first and second walls and the tying apparatus 10.
In the embodiment of Figs 7-10 the wall tying apparatus 40 comprises an elongate member 41 of stainless or galvanised steel formed by one or more metal stamping or pressing operations. The member 41 comprises a generally plate-like portion 42 having its two opposite, longitudinal edges 44 folded over backwardly to provide edge reinforcement or rigidity. A plurality of longitudinally directed fixing holes 55 are provided in plate-like portion 42 in a similar manner to the holes 25 in the plate-like portion 12 in the embodiment of Figs 1-5. Apart from the region of its two opposite ends, the attachment member 41 has four conical depressions 56 equi-angularly spaced around each elongate hole 25. These conical depressions 56 serve the same function as the conical depressions 26 provided, in rows of three, adjacent to each side of each elongate hole 25 in the embodiment of Figs 1-5.
The attachment member 41 is also stamped or pressed to provide pairs of straps 45 following a somewhat V-shaped or truncated-triangular or a semi-circular path and standing proud forwardly of the the front face of the plate-like portion 42. The straps 45 are arranged in two columns, i.e.
they are equi-spaced from the vertical centre line of member 41, and are also equi-spaced apart vertically by a multiple or fraction of the conventional spacing between courses of a new wall of brick or block.
Tie members 46 to be retained by the straps 45 are formed of galvanised or stainless steel wire bent to generally Ushape. The two main limb portions 48 (that are interconnected by bight portion 47) may be of sinuous or of linear form and, in either case, are preferably closer together at their ends 50 remote from the bight portion 47 than adjacent said bight portion 47. At 50, the two main limb portions 48 extend contiguously into two mutually parallel engagement portions 51 directed at right-angles to the main limb portions 48.
For use, the elongate member 41 is fixedly attached, in upright attitude, to the existing (first) wall at the location where the new (second) wall is to be built to extend at right-angles to the existing (first) wall. The mode of attachment is by screws or coach-bolts through the elongate holes 25, preferably adjacent the bottom of these holes.
As the new (second) wall is built up with the end bricks or building blocks of the new wall abutting endwise onto the upright elongate member 41, a tying member 46 can be attached by its engagement portions 51 to the member 41 and have its tying portion 49 (provided by main limb portions 48 and bight portion 47) inserted into the mortar or cement between two courses of the new (second) wall. To achieve this, the tying member's two engagement portions 51 are vertically inserted slidingly - downwards or upwards behind a pair of straps 45 (i.e. between the straps and the adjacent plate-like portion 42). Following insertion, the tying portion 49 extends substantially horizontally so as to be embedded into the mortar or cement between the end bricks or building blocks of two superimposed courses of the new wall.It will be appreciated that a reaction to bending of the wire tying member 46 is provided by engagement of the two vertical portions 51 with the two straps 45 and with the plate-like portion 42 both above and below the straps 45.
It will be appreciated that the straps 45 provide in use for vertical sliding motion of the tying members 46 relative to the plate-like portion 42, and for such motion to be guided and laterally confined by the straps. Such motion can, for example, arise due to differential settlement of the first and second walls. Moreover, the elongate holes 25, being directed longitudinally of member 40, in use permit vertical relative sliding between member 40 and the existing wall to which it is attached. Thus relative vertical movement can be permitted between the new wall and the plate-like portion 42 and also between the plate-like portion 42 and the existing wall.In practice, it is expected that such relative vertical movement of the two walls will be initially accomodated by relative sliding movement between the tying members 46 and the upright attachment member 41, and that only after the maximum possible sliding displacement has been taken up - when the tying members 46 abut the top of, and yet remain retained by, the straps 45, that further relative vertical movement of the two walls can be accomodated by relative sliding movement between the elongate attachment member 41 and the screws or bolts that extend through the fixing holes and attach the member 41 to the first wall.Accordingly, it is considered that the tying apparatus 40 as a whole can permit severe differential settlement between the new and the existing wall to be accomodated with little or no detriment to the restraint provided by the tying apparatus against relative horizontal movement of the two walls. Nevertheless, prior to (or in the absence of) such differential settlement, any mortar or cement from the new (second) wall which, during construction, passes through and behind the plate-like portion may potentially enhance bonding between the first and second walls and the tying apparatus 40.
It will be noted that the end elongate hole 55 at the top and at the bottom of the attachment member 41 extends into close proximity to the adjacent end edge of the member 41 and therefore has its endmost conical depression omitted, i.e. the endmost elongate hole 55 has just three rather than four such adjacent conical depressions 56. Nevertheless, when two members 41 are fixed to the existing wall in longitudinal alignment and with bottom hole 55 of the upper member 41 in registry with the top hole 55 of the lower member 41, the two lateral ones of the conical depressions of the two members 41 nest within one another and the single threaded fixture (that extends through the two overlapping holes) is closely surrounded by four equiangularly-spaced bowing restraints provided by said conical depressions.
It will be apparent that the illustrated tying apparatus 10 has no forwardly extending alignment flange for the new wall. The same is true for the illustrated tying apparatus 40. The absence of any such alignment flange enables the same size tying apparatus 10 or 40 to be used for building new walls having a range of thicknesses, i.e. walls built of bricks or building blocks of more than one size. For example, a new wall of width 75, 100, 125, 150 or 200mm can be built onto an existing wall using tying apparatus 10 or 40 having the one width of 74mm. Moreover, the arrangement allows the same tying apparatus 10 or 40 to be used in the attitude shown or upside down, i.e. rotated by 1800 about a horizontal axis perpendicular to the plane of the plate-like portion 12 or 42. In other words, each of the tying apparatuses 10 and 40 is not "handed". However, the same "non-handed" advantage would still be obtained were either of the illustrated tying apparatuses 10 or 40 modified to incorporate a forwardly extending alignment flange (providing the apparatus with a generally L-shape crosssection) for aligning the new wall, and such a modification is to be deemed within the scope of the present invention.
