STATIbar helical bar

Helical stainless-steel support from austenitic steel

STATIbar additionally glued-in helical support has been developed to deal with defects of building structures of static nature. Currently, this system is used as a support for masonry structures, composite and stone walls, and it supports and repairs cracks and defects of concrete structures.

Static securing of arcade arches

STATIbar drawbars are supplied in lengths up to 10 m; they may be inserted separately or in several pieces in a single channel. This method of use enables to create glued-in crowns, head-blocks and beams. Individual 1 m bars inserted in separate channels is called crack stitching.

Benefits of the system of STATIbar helical supports

  • Without further surface finishing, minimum coverage possible, does not limit channel dimensions.
  • Minimizes interventions in the structure with concurrent extreme load capacity.
  • Helical stainless-steel support can be bent and shaped easily according to the course of prepared channels and bores.
  • Single channel may accommodate several bars and thus increase efficiency of the support.

Use of STATIbar helical bar

Glued-in crowns in the masonry without the need of roof lifting.

Where a collapse of the roof structure occurs (new roof covering, decay of crossbeams), the masonry is often cracked just below the roof in case of crown absence. The STATIbar system may be used herein, inserted in milled channels – two pieces in a single channel in two layers.

Glued-in beam above cracked head-blocks of construction openings.

To transfer the pressure in the opening head-block that caused cracks, a glued-in support is used in milled channels - two pieces in a single channel in two layers above the opening.

Glued-in beam for distribution of the point load of micro-piles.

Where the loss of foundation load capacity occurs and STATIpile micro-piles need to be applied. Micro-piles transfer the point load to the masonry. To distribute these forces over the total masonry length, we use the STATIbar system inserted into milled channels – two pieces in a single channel in two layers above the head of micro-piles.
