SCHALL-ISOBOX® type TSB Impact sound reduction ≥ Lw*=23 dB IMPACT SOUND BOX FOR STAIR LANDINGS APPLICATION AREA The SCHALL-ISOBOX® TSB is used to isolate the impact sound generated in staircases between stair landings and staircase walls so that it is not transferred into living or working areas. The SCHALL-ISOBOX® is made of polyethylene with integrated elastomeric bearings to transfer the load. Depending on the design, positive and/or negative shearing and horizontal forces can be transferred. ▪▪ Type-tested ▪▪ Considerable impact sound reduction ▪▪ R90 fire safety inspection report ▪▪...

ARRANGEMENT OF THE ELEMENTS NOTES It is recommended that the landings are supported at four points using ISOBOX® elements. The SCHALL-ISOBOX® may, of course, be arranged differently for specific staircase or landing types. SUGGESTED ARRANGEMENT FOR SCHALL-ISOBOX® TYPE TSB - FLOOR PLAN Stair landing Stair landing TSP PL peripheral impact sound plate Flight of stairs and landings Support on opposite sides of the landing Stair landing Stair landing TSP PL peripheral impact sound plate Flight of stairs and landings Support on opposite side and adjacent side of the landing

TSB-F PRODUCT VERSION APPLICATION Isolation of the impact sound generated in prefabricated landings and staircase walls SYSTEM COMPONENTS RATED VALUES FOR CONCRETE ≥ C20/25 Element TSB-F * With a landing thickness < 180 mm, the finished bracket in the SCHALL-ISOBOX® must be filled with mortar (MG IIa). DIMENSIONING THE CONNECTING LANDING SLAB Evidence of the transfer of forces into the neighbouring component must be provided by the responsible structural engineer in all cases. The properties of the connecting slab can be verified as follows: ▪▪ Use of flush beams as bar-like connections to...

INSTALLATION INSTRUCTIONS TSB-F: INSTALLING THE PREFABRICATED PART Prefabricated landing slab support bracket ▪▪ Produce a landing slab with bracket supports ▪▪ With regard to the landing size, the thickness of the surrounding TSP impact sound plate must be taken into account; see page 36 ▪▪ After removing the formwork, fit the impact sound box onto the bracket. Note the "THIS SIDE UP" marking TSB-F: INSTALLING THE PREFABRICATED PART ON THE BUILDING SITE ▪▪ Bond the impact sound plate type TSP to the side across the entire surface ▪▪ Align the prefabricated landing with attached impact...
