Description

A holder for a wall tie
Description
Technical Field
[0001] The invention relates to an improved holder for a wall tie. The invention also relates to a wall tie and to an assembly comprising a holder for a wall tie and a wall tie.
Furthermore the invention relates to a method to install a wall tie in a holder for a wall tie.
Background Art
[0002] It is common practice to secure masonry walls, such as fagades or load- bearing walls to a structural or supporting element such as a load-bearing wall or a column as for example a reinforced concrete column or any structural or supporting element known in the art. Securing a masonry wall to a structural or supporting element may be achieved by anchoring the wall to the structural or supporting element at regular vertical and horizontal intervals. To secure a wall to a structural or supporting element, the use of wall anchors is known in the art. Various
embodiments of wall anchors are known in the art.
Examples of wall anchors are for example known from ES 1070021 , US2007/0062138 and GB2395497.
ES1070021 describes a wall anchor comprising a holder for a wall tie having a rear portion and two side portions whereby both side portions are provided with an opening to hold the legs of a wall anchor tie.
US2007/0062138 describes a holder for a wall tie comprising a rear portion (backing member) and a projection member defining a first and a second slot between the rear portion and the projection member.
For the holders for a wall tie described in ES 1070021 and
US2007/0062138 the wall tie is introduced in the holder by first sliding the wall tie laterally through the first opening or slot and subsequently through the second opening or slot. This way of inserting the wall tie in the anchor is requiring toilsome efforts from a mason.
GB2395497 describes a wall anchor comprising a holder for a wall tie having partially circular slots for receiving a correspondingly shaped portion of a wall tie made of a sheet of steel.
Disclosure of Invention
[0003] It is an object of the present invention to provide a holder for a wall tie avoiding the drawbacks of the prior art.
It is also an object of the present invention to provide a holder for a wall tie allowing quick and easy installing of a wall tie in the holder.
It is another object of the present invention to provide a method to install a wall tie in a holder for a wall tie.
It is a further object of the present invention to provide a holder for a wall tie that may be used to insert wall ties provided with at least one spacer element.
It is furthermore an object to provide an assembly comprising a holder for a wall tie and a wall tie.
[0004] According to a first aspect of the present invention a holder for a wall tie is provided. The holder is provided with at least a first open-ended slot and a second open-ended slot. The first open-ended slot and the second open-ended slot are designed for receiving and holding a wall tie.
The first open-ended slot has a first open end and the second open-ended slot has a second open end. The first open end of the first open-ended slot and the second open end of the second open-ended slot are oriented in different directions.
When the wall tie is installed in the holder, the wall tie is installed in both the first open-ended slot and the second open-ended slot.
[0005] The wall tie comprises preferably a wire.
[0006] The wall tie is preferably introduced in the holder by sliding the wall tie, for example the central portion of the wall tie, through the first open end in the first open-ended slot and through the second open end in the second open-ended slot. More preferably, the wall tie is introduced in the holder by frontally sliding the wall tie through the first open end in the first open-ended slot and subsequently through the second open end in the second open-ended slot.
[0007] The easiness of installation of a wall tie in a holder according to the
present invention is an important advantage of the holders according to the present invention compared to holders known in the art. Holders known in the art as described in ES 1070021 and US2007/0062318 require that the wall tie is introduced in the holder by laterally sliding the wall tie through a first opening and subsequently sliding the wall tie through a second opening. The introduction of a wall ties in the
conventionally known holders is considered by a mason as a difficult, toilsome and time-consuming operation.
[0008] For the purpose of this invention, with "frontally sliding" is meant
positioning the wall tie in front of the holder, for example against the front of the holder, and subsequently sliding the wall tie in the open-ended slots, either simultaneously or subsequently. The wall tie is thereby slid through the open end of an open-ended slot in the open-ended slot.
With "laterally sliding" is meant sliding the wall tie through an opening or slot from one side of the holder.
It is important to notice that "frontally sliding" is not possible in case the slots or openings do not have an open end.
With "slot" is meant an opening, preferably a narrow opening or a groove. With "open-ended slot" is meant a slot having an open end, i.e. a slot having an end with an opening that is allowing that an object, such as a wire is slid through the open end in the open-ended slot.
With "the first open end of the first open-ended slot and the second open end of the second open-ended slot being oriented in different directions" is meant that in case a first vector having a direction parallel to the longitudinal axis of the first open-ended slot and pointing towards the first open end is drawn in the first open-ended slot; and a second vector having a direction parallel to the longitudinal axis of the second open- ended slot and pointing towards the second open end is drawn in the second open-ended slot; either the direction or the orientation of the first and the second vector is different.
[0009] In a preferred embodiment the holder comprises a rear portion, a first side portion and a second side portion. The first side portion and the second side portion are preferably transverse to the plane of the rear portion. In this way the rear portion, the first side portion and the second side portion may define a channel, preferably a U-shaped channel.
For receiving a wall tie, the holder is provided with at least a first open- ended slot and a second open-ended slot.
Preferably, the first side portion is provided with the first open-ended slot and the second side portion is provided with the second open-ended slot. The wall tie can be introduced in the holder by sliding the wall tie, for example the central portion of the wall tie, in the first and the second open-ended slot.
In such embodiment the wall tie can for example be introduced by frontally sliding the wall tie through the first open end in the first open-ended slot and through the second open end in the second open-ended slots.
[0010] As mentioned above, the first open end (of the first open-ended slot) and the second open end (of the second open-ended slot) are oriented in different directions. In a preferred embodiment the first open end and the second open end are oriented in mutual opposite directions. The first open end is for example oriented to the upper side of the holder whereas the second open end is oriented to the lower side of the holder. A wall tie can be introduced in such an embodiment of a holder by sliding, preferably frontally sliding, one end of a wall tie downwards in the first open end slot and another end of a wall tie upwards in the second open end.
In a preferred embodiment the holder has a first side portion provided with a first open-ended slot with its open end (the first open end) oriented towards the upper side of the holder and a second side portion provided with a second open-ended slot with its open end (the second open end) oriented towards the lower side of the holder.
[001 1] The open-ended slot or slots may have any shape. Preferably, the shape of the open-ended slots allows easy introduction of a wall tie in the holder. In addition it is preferred that the shape of the open-ended slots does not allow easy removal of the wall tie from the holder once the wall tie is introduced in the holder.
By using open-ended slots having a shape that at the one hand allows easy introduction of the wall tie in the holder and at the other hand makes it difficult to remove the wall tie from the holder once introduced; complex, toilsome and time-consuming operations to introduce the wall tie in the holder are avoided and at the same time the risk that the wall tie is removed or slipped out of the holder for example by accident is reduced to a minimum.
[0012] For a person skilled in the art it is clear that the open-ended slots may be provided with any kind of means to hold the wall tie in the open-ended slots once the wall tie is introduced in the slot. In preferred embodiments the open-ended slots can be provided with extensions as for example barbs to hold the wall tie in the open-ended slots once the wall tie is introduced in the slot.
[0013] The holder can be fixed to the structural element by any means known in the art, such as any anchoring means known in the art.
In a preferred embodiment the rear portion of a holder is provided with at least one slot for accepting at least one anchoring means. The slot of the rear portion is preferably an elongated slot allowing adjustably mounting of the holder to the structural element.
[0014] The holder according to the present invention is designed to receive and to hold a wall tie. The wall tie preferably comprises a wire, for example a bent or deformed wire.
The wall tie comprises for example a wire comprising at least a central portion, a first leg and a second leg, each of said first and second leg extending from the central portion. In some embodiments the first and second leg may have further legs (side legs) extending from the first and second leg.
The wall tie is preferably introduced in the holder by sliding the wall tie through the first open end in the first open-ended slot and through the second open end in the second open-ended slot.
Preferably, the wall tie is installed in the holder by sliding the wall tie frontally in the first open end and the second open end.
