Sraigtiniai pamatai – protingas pamatų įrengimo sprendimas

Pamatų tipai
Statinio pamatas – statinio dalis, kuri perima
apkrovas, perduoda ir paskirsto jas į pagrindą. Pamatai – viena svarbiausių statinio konstrukcijų, nes
nuo jų priklauso statinio ilgaamžiškumas, šilumos ir vandens izoliacija bei
estetinis vaizdas. Neteisingai parinktas pamato tipas, esant silpniems
gruntams, gali nulemti netolygius pamato ir kartu viso statinio nusėdimus, kas
susilpnina statinį, gali sukelti jo griūtį.
Populiariausi ir Lietuvos klimato sąlygoms
geriausiai pritaikomi trys pamatų tipai: juostiniai, poliniai ir plokštuminiai.
Polinius pamatus tikslinga rinktis, kai stiprus gruntas slūgso giliai. Polinių
pamatų įrengimas yra pigesnis už juostinių, taip pat kai kuriais atvejais tai
yra vienintelis pamatų tipas, leidžiantis konkrečiame sklype apskritai statyti
statinį. Sraigtiniai pamatai priklauso būtent
polinių pamatų grupei.
Sraigtinių pamatų privalumai
Sraigtiniai pamatai (sraigtiniai poliai) – protingas
pamatų įrengimo sprendimas, leidžiantis atsisakyti brangių ir sudėtingų,
darkančių aplinką kasybos darbų. Montuojant sertifikuotus vokiškus sraigtinius
pamatus (sraigtinius polius), nereikia naudoti betono, armatūros, nereikia
gręžti ar kasti grunto.
Sraigtinių pamatų (sraigtinių polių) įrengimo
principas, kaip teigia specialistai, yra analogiškas medsraigčio įsukimui. Sraigtinis
polis įgręžiamas į gruntą, veikiant jį 4700–15000 Nm jėga sukimo momentu.
Įgręžiamas sukimo būdu, o ne įkalamas, kaip kaltiniai poliai. Būtent dėl šio
veiksmo sraigtinis pamatas tvirtai įsispraudžia į gruntą, jo neišjudindamas.
Polinių pamatų veikimo principas yra rėmimasis į
tvirtesnį gruntą apačioje ir šoninė trintis. Būtent todėl standartiniai
betoniniai poliai gilinami daugiau ir daromi storesni. Pirmiausia, kad pasiektų
kuo tvirtesnį gruntą. Dėl didesnio skersmens ir ilgio polinis pamatas turėtų
daug didesnį sąlytį su gruntu, o tai reiškia – ir didesnę trinties jėgą, kurią
reikėtų įveikti polį veikiant statinio svoriui.
Sraigtiniai pamatai pranašesni, nes smigdami į
žemę tankina apie save gruntą. Sraigtiniai pamatai turi nepertraukiamą sriegį,
kuris, įsriegus, sukuria daug atramos taškų per beveik visą pamato ilgį. Norint
įstumti sraigtinį pamatą, kad jis sėstų gilyn, reikia labai didelės jėgos, kuri
įveiktų visus atramos taškus ir trintį.
Sraigtinių pamatų techninės charakteristikos
Vokiški sertifikuoti SPF sraigtiniai pamatai gaminami iš S235 plieno ir yra karštai cinkuoti
iš abiejų pusių pagal DIN EN ISO 1461 (tiek
išorė, tiek sraigto vidus). Sraigtinio pamato skersmuo siekia iki 140 mm, ilgis gali siekti ir 6–8 metrus,
sienelės storis siekia 5,6 mm. SPF pamatams būdingas nepertraukiamas spiralės
suvirinimas (sertifikuota konstrukcija DIN
EN 12699, patvirtinta 07/2015). Sraigtinių pamatų bandymai atliekami
vadovaujantis EURO COD 7 DIN 1054/2010 EA. CE sertifikatas – pagal DIN EN 1090 / TÜV Rh.
Sraigtinis pamatas atlaiko iki 8,5
tonų spaudimo apkrovą. Pavyzdžiui, 3 metrų ilgio 140 mm skersmens
sraigtinis pamatas, kurio sienelės storis siekia 5,6 mm. Jei statiniui,
konstruktyvui reikalingas didesnis efektyvumas, sraigtinius pamatus galima jungti tarpusavyje
traverso pagalba. Taip efektyvumas padidinamas kelis kartus.
Sraigtinių pamatų įrengimas nereikalauja jokių žemės darbų, jokio betono,
todėl jums nereikės tvarkyti gerbūvio. Sraigtiniai pamatai montuojami visus
metus, net ir žiemą. Metų laikas nedaro
jokios įtakos sraigtų montavimui.
Sraitginių pamatų panaudojimo galimybės
Kokybiški sertifikuoti vokiški sraigtinių pamatų sprendimai
leidžia įrengti ilgaamžius tvirtus pamatus greitai ir efektyviai. Pamatams
įrengti nenaudojamas betonas ar armatūra. Esant poreikiui, pamatus galima
išsukti iš grunto. Sraigtinių pamatų sprendimas yra ne tik efektyvus, taupantis
jūsų laiką ir pinigus, bet ir tausojantis gamtą.
Sraigtiniai pamatai efektyviai pritaikomi
rengiant pamatus karkasiniams namams, pirtims, pavėsinėms, garažams, terasoms,
tvoroms. SPF pamatai pasitarnauja rengiant vaikų žaidimo ir sporto aikšteles,
ieškant miesto apšvietimo ir kelio ženklinimo įrengimo sprendimams. Tai –
idealus sprendimas parkų projektams, kai infrastruktūros elementams įrengti
būtina surasti saugiausią, mažiausią įtaką aplinkai darantį sprendimą.
Kalbant apie sraigtinių pamatų įrengimą vandenyje
– tai bene pats patikimiausias ir paprasčiausias sprendimas. Lieptai, terasos,
net pirtys vandenyje tampa nesudėtingai įgyvendinama realybė. Pamatus vandenyje
rekomenduojame montuoti žiemos metu, kai vandens telkinys padengtas ledu.
Kiekvienu atveju mūsų specialistai konsultuoja ir
parenka individualius sprendimus, kuriuos patys ir įgyvendiname. Atsižvelgus į jūsų projektą, paskaičiuojame
reikiamą sraigtinių pamatų kiekį ir dydį. Naudojant specialią techniką
sraigtiniai pamatai sparčiai įsukami į bet kokį gruntą. Priklausomai nuo
grunto, per darbo diena dviejų žmonių komanda gali sumontuoti nuo 20 iki 50 sraigtų. Pamatai tampa
paruošti naudojimui iš karto po montavimo. Patyrusių meistrų komandos dirba visoje Lietuvoje.

Sveiki reikėtų apie 26m2 terasai susukti polius domina kaina ir kaip greitai padarote nuo užsakymo. Ačiū 867087090
Sveiki, mane domina sraigtiniai pamatai, pirmiausia norėčiau išsiaiškinti kokiu man jų reiktų, bus statomas karkasinis namas vieno aukšto, namo išorės matmenys 7.8mx11.8m vidaus plotas apie 80kw2. Kiek maždaug sraigtu reiktų ir kokio ilgiaus bei plociaus? Ir kokį būtų maždaug kaina su montavimu ir be montavimo? Veiksmas vyktų Skuodo mieste, ačiū, lauksiu atsakymo :)
Sveiki,norėčiau sužinoti kiek ir kokių reiktų sraigtinių pamatų 50 kv.sodo vasarnamiui,namo išorės matmenys 10×6.kokia būtų montavimo,ir be montavimo kaina,ačiū
