  • holes are drilled in the bricks the transport anchors depending on the position of the bricks introduced in the wall panel, such that the holes in the stacked bricks of the wall panel aligned with each other, i.e. over the entire height the vertical panel recesses extending the wall panel form.
  • Standard masonry blocks can therefore be used without grid holes be, while preparing the stones for bricking at the locations provided for the transport anchors in the holes corresponding to individual stones are drilled.
  • the Places provided for the lifting anchors are dependent determined by the position that the corresponding brick will take later in the wall panel.
  • two holes can be made in a wall panel with 5 cm diameter at a distance from the required transport anchors from e.g. 2.5 m can be introduced, whereby for the Brick tolerance no addition to the bore diameter necessary is. There is no measurable reduction due to the two holes thermal insulation of a 38 cm thick outer wall.

  • the control device can determine the location of a brick take this in the wall row or in the finished wall panel will determine, and depending on this, the drilling device control and position. This can do this at least along the row of brick blocks designed to be relatively movable his.
  • An alternative to the movable drilling device is one stationary drilling device integrated in the stone cut represents.
  • the drilling device is expediently the line-up section for the stones assigned to a row of walls, so that the holes inserted in the bricks for the transport anchors can be if they are next to each other on the line lined up according to their later arrangement in the wall panel are.
  • the bores or holes can already be made in the Production can be brought into the stone factory. This without the Disadvantage of the loss of thermal insulation of the wall Bricks with grid holes if in the production of Wall boards a line-up device for the production of a Wall board row is used, which is able to between Sort whole stones without a hole. So that the holes are in the intended place in the wall, it may be necessary to cut the perforated bricks to length.

  • the foot beam not only improves the stability of the whole Wall improves, but also prevents stones fall down when transporting wall panels with one Crane commutes the wall panel against the building.
  • a under the wall panel arranged two foot beams along the wall panel extending at a distance arranged footboard elements be provided on which the bricks are bricked up be, using a transport anchor, the lower end that is in the space between the two Joist elements, e.g. spirally curved is.
  • the gap there is at least one along the wall slab extending longitudinal rod inserted.
  • the curved end of the lifting anchor in the space becomes in brought a position under the longitudinal bar, for example by rotating the lifting anchor around its longitudinal axis. After filling the gap through the passage recess with binding agent becomes a firm connection between the horizontal longitudinal bar and the vertical one Transport anchor manufactured.
  • a transport anchor with a ribbed surface can also be used with the ribbed end at such a distance applied to the longitudinal bar that an anchoring effect arises in concrete. That means that the anchorage can also be done without a lower trimmed end of the lifting anchor is made, if the vertical anchor rod is close enough to that Longitudinal bar lies, so that the shear force transmission of the concrete is sufficient. In other words, it is essential Formation of the lower end of the rod-shaped lifting anchor, that he is brought into operative connection with the longitudinal bar becomes.
  • Clamping grabs are preferably used to transport the wall panels used that grab the lifting anchor and under clamp the effect of the load of the raised wall panel. Such clamp grippers are used, for example, for clamping Bars in testing machines to determine the breaking strength of Rods inserted. Clamping grabs have the advantage that in the wall panels no expensive anchors with pressed on them Hook loops need to be poured in as is the state of the art Technology is that automated gripping of the Wall boards is very easy and that even Lifting a wall by clamping several at the same time Anchor rods is possible if one equipped with several clamps Hanger is used.
