Sprijinirea traverselor, grinzilor, fermelor, etc. cu distante mari de deplasare si sarcini de suprafata mici
Suporti elastomerici glisanti ne-armati tip NEG cu AbP (General Construction Supervision Certificate) pentru toti suportii cu deplasari mari la comprimari de pana la 5 N/mm2. Coeficient redus de frecare si stabilitate functionala maxima asigurate datorita potrivirii dispozitivului glisant de inalta calitate. Suportii elastomerici glisanti ne-armati absorb deplasarile orizontale prin intermediul placii de glisare de pe suportul lagarului. In acelasi timp, asigura o distributie controlata a sarcinii si compenseaza torsiunii sistematice in suporti, precum si inegalitati si deviatii de la paralelismul suprafetelor.

Band spacers with elastomer core, type TDG 27 SZ
Product description
The type TDG 27 SZ linear spacers are band slip spacers, composed of an EPDM-based vulcanised rubber core and filler foam. The spacer also has a double-layer HDPE-based slip film with a layer of Renolit Fol 2 lubricant, and in addition the entire composition is laminated to ensure protection during transport and installation.
They are foreseen for bearing of flat roofs, ceilings, beams and joists. These spacers allow free movement of slabs and beams of up to ± 20 mm, for tension force values up to 2 N/mm2. They prevent the emergence of rifts caused by horizontal shifts, they protect the edges of the support surface from excess load, and they counteract the emergence of rifts caused by walls slanting.
hese spacers are used for supporting monolithic reinforced concrete components and precast parts.
By placing the linear spacer with an elastomer core in the centre of the support area, i. e. the wall (core axis must ideally match the wall axis), the load from the supported component, i. e. the ceiling, is transferred just to the support component axis.
The type TDG 27 SZ non-reinforced elastomer slip spacers are manufactured as rectangular plates.
Dimensions:
- thickness t: 7 mm, 12 mm
- thickness d: 5 mm, 10 mm
- side dimensions:
-
minimum width b: 115÷500mm
- elastomer core width bE: 25÷100mm
Designation:
t – spacer thickness, mm
d – elastomer core thickness, mm
b – spacer width, mm
bE – elastomer core width, mm
l – spacer length, mm
The TDG 27 SZ type spacers can be manufactured in any selected dimensions. The standard spacer length is one running metre.
Technical and assembly hints
Elastomer spacers must be placed on support components close to the reinforcement bars of the support component. Spacers should be installed with the elastomer core downwards.
Fire resistance characteristics
The non-reinforced linear elastomer spacers hold fire examination certificate no. LPP01-1256/12/200NP conducted by the Fire Research Department of the Polish Building Research Institute. According to the test report, the line spacers conform to the requirements for fire resistance class REI 120. When choosing spacers, one needs to consider the scope of spacer damage/degradation according to the table included in the Technical Approval, available at the website www.betomax.pl in the Downloads section.
