Dilatacione spojniceza eleznicu imaju

sledee funkcije:

dozvoljavaju pomeranja izmeu

ploa,omog uava ju dren au i

filtraciju atmosferskih voda,

daju kontinuitet konstrukcije ploa,

spreavajui prodiranje tucanikog

zastora u dilatacioni zazor,spreavaju prolazak lutajue

struje.

Dilatacije Algaflex TW za eleznice u

seizmikim podrujima su odobrene od

strane Ferrovie dello Stato i odgovaraju

propisanim uslovima.

ALGAFLEX dilatacije su napravljeneod elektrino neprovodljivih gumen ih

elemenata, vulkanizovanih preko unu-

tranje metalne konstrukcije.

Ova konstrukcij a, koja se ponaa

kao anker i armatura, je potpuno presvu-ena gumom.

ALGAFLEX TW elementi su privr-

eni za plou hemijskim ankernim

zavrtnjima, dozvoljavajui deforma-

ciono pomeranje gumenih slojeva,

ukljuujui i izmeu metalne konstrukcije.

Dilatacije se vezuju nastavkom pero-ljebi zaptivene specijalnim lepkom.

Nepropusno neoprensko platno je oblika

grkog znaka omega i montira se popreno

u odnosu na konstrukciju.

Dilatacija za koju se daje garancija od

10 godina, otporna je na ulja, masti, gorivo,

so i pesak. Toplota, izloenost suncu,hladnoa i sneg ne prouzrokuju prevre-

meno starije.

Pokrivne ploe za peake staze dozvo-

ljavaju pomeranje du razliitih

delova konstrukcije, spreavaju da

tucaniki zastor ili strana tela prodru u

zazor i garantuje elektrinu izolaciju.

The railways expansion joints have the

following functions:they allow the movements between the

decks,

they permit the drainage and preventthe percolation of the meteoric waters,they give a structural continuity to the

slabs, avoiding the penetration of the

ballast in thegap,They prevent the forward of stray

electrical currents.The TW Algaflex joint for railways inseismic areas, has been ratified by"Ferrovie dello Stato" and complies withthe specifications.

The Algaflex joints are made of dielectric rubber elements, vulcanised

to the innermetallic structure.This structure, which acts as anchor and

reinforcement, is completely covered by

the rubber.The Algaflex TWelements are restrained

to the slabs by chemical anchor bolts,

allowing the deformation movement of

the rubber layers included between the

metallic structures.The joints are connected by male-

fem ale jun ctions and sealed wit h

special glue.

The dielectric flashing is shaped

andis put across allthe structure.The joint, guaranteed for 10 years, is

resistant to oils, grease, petrol, salts

andsand.Hea t, exp osu re to the s un, col d, sno w

d o n o t c a u s e e a r l y a g e i n g

phe nom ena .

The cover plate for the sidewalks

allows the movements among the

different parts of the structure; it

avoids to ballast or foreign bodies to

enter the gap and guarantees the

electricisolation.It is pos sib le, therefo re, to ben d the

cover plate against the kerbs of the

sid ewa lks .

When the skew angle is higher than10 the cover plates can replace the

bendedpartontheendofthejoint.
