Description

The present invention relates to a brickwork support assembly for anchoring and/or support of a brick (outer) wall to a anchoring base, like a concrete inner wall or a concrete skeleton construction, comprising a bracket anchor provided with two essentially parallelly sidepieces; a brickwork carrier suitable for incorporating into brickwork wall, the carrier being fixedly attached to the front side of the sidepiece elements; mounting means, like a screw bolt with nut, for mounting the bracket anchor onto the anchoring base; a support bracket for the mounting means, the opposing edges of the bracket are provided with first flanged rims, extending in the same direction around the sidepiece elements.
These brickwork supports are used to support outer brickwork or mortar walls of great height at regular (vertical) distances and to anchor the brickwork to an inner wall or (concrete) construction. Thereby the vertical pressure exerted by the high brickwork walls is decreased.
Such an anchoring device is known form European patent 0 212 228 B1 . This well known anchoring device is used for anchoring slabs onto an anchoring base like an inner wall.
This known anchoring device has a number of disadvantages.
It was found that this device and construction in mounted and loaded position gradually looses its strength and stiffness. As a consequence the outer brickwork wall may become instable prematurely necessitating renovation of the brickwork support and/or of all of the brickwork or even a complete renewal and rebuild of the brickwork. In order to prevent such problems the parts may be manufactured from a thicker material; this has financial and constructional disadvantages, because the price of the brickwork supports will increase and the load bearing parts of the building structure may be required to be of a heavier construction due to the higher weight load.
The object of the present invention therefore is to provide for a long lasting stable and stiff support, which is lightweight and moreover may be manufactured easily at low costs.
This object is achieved by the brickwork support assembly according to the invention whereby the sidepiece elements with their upper sides are interconnected by a bridge element or the bracket anchor is a one piece construction having a U-shape with downwards extending leg portions; the support bracket is provided with a saddle-shape, by providing the adjacent edges - of the edges having the first flanged rimswith second flanged rims extending in the opposite direction relative to the first flanged rims.
With this construction according to the invention having transverse connections at the upper and lower side of the sidepiece elements in combination with a very stiff support bracket as a third transverse connection, surprisingly a long lasting rigid and stable anchor bracket is obtained without the necessity of having to use material of increased thickness. The anchor bracket may be manufactured easily and at low costs by bending and cutting.
In a preferred embodiment the saddle-shaped support bracket is rotation symmetric. Consequently errors during mounting are prevented and thereof possible weakening of the support.
Preferably the sidepiece elements are provided with strut supports connected with the bridge element or the sidepiece elements of the U-shape are provided with large recesses configuring strut supports. By these measures a strong, lightweight and easily manufacturable brickwork support is obtained.
The embodiment is preferred whereby the sidepiece elements at their rearward side (anchoring side) are provided with recesses for mounting an adjustment assembly.
Advantage is offered by the embodiment wherein the recesses are provided with a constriction at the rearward side of the sidepiece portions.
More in particulier the assembly is provided with a detachable adjustment assembly configured to be mounted into the recesses of the sidepiece elements.
More in particulier the adjustment assembly comprises a square pipe and a spindle with a stop piece for the anchoring base.
Particularly the pipe is provided with grooves for receiving the side piece elements.
Advantageously with these means a lightweight, but a structural stable and rigid brickwork support construction is obtained, whereby the straight, square, shape of the adjustment assembly pipe prevents bending or fracturing of the sidepiece elements and reduces quick deformation of the elements - in mounted position - as result of variations in the pressure load.
The invention will be further explained by means of a drawing of an embodiment of the brickwork support, which will elucidate its characteristics and other advantages.

Fig.9 shows the bottom part of the locking plate with accompanying slots which are fitting for the edges of the sidepiece elements of the bracket anchor.

Fig.1A - 1D show brickwork support 1 according to the invention comprising U-shaped bracket anchor 2 with two sidepiece elements 3', 3" and a bridge element 9. Brickwork carrier 4 is fixedly attached to the front side of the sidepiece elements 3', 3". The brickwork carrier 4 is positioned between the bricks of the outer mortar wall 20 (see figure 3) in order to reduce the pressure forces in a brickwork wall having a great height. The brickwork support 1 is connected, by means of mounting means 5 - in this embodiment consisting of a T-head bolt and nut - with anchor rail 31, being the anchoring base. The brickwork support may be connected with the anchoring base in an alternative way, e.g. by means of (chemical) anchors/plugs. Between anchor rail 31 and the brickwork support 1 an adjustment plate 30 is mounted so that as a result the position of the brickwork support 1 may be adjusted to the variations in the brickwork of the outer wall. The horizontal variations in the distance between the anchoring base and the outer wall may also be corrected by means of the adjustment plate 30.
The stiffness of the shown brickwork supports is obtained by interconnecting the sidepiece elements 3', 3" at their upper sides with a bridge element 9 or to form the bridge element 9 and the sidepiece elements 3', 3" as a one piece construction; and furthermore by connecting the sidepiece elements at their front side with the brickwork carrier 4 and by connecting the bracket anchor 2 onto the anchoring base by means of mounting means 5 in combination with a saddle shaped support bracket 6. As a consequence of its special saddle-shape the support bracket 6 will hardly bend under the influence of the occurring forces, e.g. caused by differences in the outside temperature. Therefore the brickwork support 1 will not quickly become loose or otherwise decrease the required anchoring support to the outer brickwork wall.
Fig 4A - 4C shows more in detail the support bracket with two pair of adjacent sides or edges 7', 7" en 11', 11". The first edges 7', 7" are provided with flanged rims 8', 8" which are extending backwards or downwards relative to the plane of the drawing. The adjacent sides 11', 11" are also provided with flanged rims 12', 12" as a result of which the support bracket 6 is a very rigid element that will not be deformed as a consequence of the normal pressure load variations in a building construction. In a preferred embodiment the support bracket 6 has a rotation symmetric shape, so that is impossible to mound the support bracket incorrectly.
In figure 3 and figure 2B an alternative embodiment of the brickwork support 1 is shown having strut supports 13', 13" which extend from the bridge element 9 to the brickwork carrier 4. Preferably these strut supports 13', 13" are configured by providing recesses 14', 14" in the sidepiece elements 3', 3", e.g. by means of cutting. The triangle thus configured in the sidepiece elements 3', 3" will allow the bracket anchor 2 to take up higher loads.
When the distance to the anchoring base is great or the brickwork support is out of alignment or is not level, such deviations may be corrected easily by means of a detachable adjustment assembly 16.
Figure 1A, 1C and 3 show an adjustment assembly 16 and Fig.5A - 5C show the preferred adjustment assembly 16 more in detail. The adjustment assembly 6 is mounted into recesses 15', 15" provided at the bottom side of the sidepiece elements 3', 3". In Fig.2A and 2B the recess 15" are shown in more detail. The recesses 15", 15" are preferably square shaped and furthermore provided with constrictions 17', 17" in order to prevent that the loose, not fixed, adjustment assembly will come out easily or fall from the sidepiece elements 13', 13". When level correction is necessary it is possible during construction to easily slide the adjustment assembly 16 into the recesses 15', 15" by guiding the spindle 19 through the constriction 17', 17". By rotating the spindle 19, e.g. by means of a screw driver, the stop piece 21 is forced against the anchoring base 10 so that the brickwork support 1 may be levelled. The adjustment assembly 16 and the recesses 15', 15" are preferably square as it has been found that in this way the support forces are transferred in a regular manner and moreover the spindle 19 with stop 21 will always be oriented in the correct mounting position. As shown in Fig.5A, 5C the square pipe 18 may also have been provided with grooves 22", 22" for receiving sidepiece elements 3", 3". In Fig.1C, 3 is shown that the sidepiece elements 3', 3" are positioned into the grooves 22', 22" in order to constitute an additional structural connection at the bottom side of the bracket anchor 2.
In figures 6A 6E, 7A - 7E and 8A - 8E some alternative embodiments are shown, partly in perspective view and partly in top and side view. Contrary to the abovementioned bracket anchor types the bridge connection between the sidepiece elements now consists of at least one closed bridge element mutually interconnecting the sidepiece elements, the element not being located at the upper side, like bridge element 9 in Fig.1A.
Both bridge element 109 and 109' are clearly visible in fig. 6B, 7B and 8B. Moreover the locking plate 106 of flat thick steel plate, at the front side of the bracket anchor, has a flat shape and is at its front side provided with two parallel slots 104, 104' for fittingly receiving the raised edges 103, 103' of the side piece elements. At the entrance side the edges of the slots are slightly bevelled off as is visible in Fig. 6D, 7D, 8D. This embodiment, as shown in Fig.9, has the advantage that the bracket anchor may take up considerably more force.
In Fig. 6C, 7C and 8C two bracket anchors are shown whereupon a brickwork carrier 104 is welded. Fig. 6E, 7E and 8E show in side view the bracket anchor with the thereto fixedly welded brickwork carrier 104 and Fig. 6D, 7D, 8D show a top view of the bracket anchor.
