HeidelbergCement peakorteri ehitus näitab tipparhitektuuri ja PERI raketise erilahendusi

18. nov 2021

Within a 16-month construction period, almost 97,500 m<sup>2</sup> of formwork solutions were used – including customised PERI special formwork elements. (Photo: Thilo Ross)
The results of using the highest quality architectural concrete class SB 4 and the finest white concrete are visible in the many architectural highlights: Spectacularly twisted tree-like supports, creatively patterned facade prefabricated concrete elements and sharp-edged beams in a radial pattern. (Photo: Thilo Ross)
The three groups of tree-like supports tower over three storeys in the foyer. PERI developed a highly complex 3D special formwork made of steel elements with an overall height of 150 mm, which consisted of 63 individually designed and CNC laser-cut individual parts. (Photo: Thilo Ross)
The formwork for the tree supports fitted into the already erected PERI UP Shoring without any problems. The compatibility of the systems was one of the decisive points why the client chose PERI.
Not only the formwork, but also the architecture of the tree supports is outstanding: in compliance with the architectural concrete quality required, only one panel joint is visible over the entire column height of around 11 m. (Photo: Thilo Ross)
The feature wall consists of several prefabricated concrete elements of the highest architectural concrete quality, which were subsequently mounted to the in-situ concrete wall. (Photo: Thilo Ross)
For the dome ceiling, PERI developed a formwork solution made with 82 factory pre-assembled, 3D-designed architectural concrete timber formers that were delivered pre-assembled to the construction site. (Photo: Thilo Ross)
For the casino slab, PERI special formwork developed especially for the project was used, which was later implemented with a total of 64 different diamond-shaped box outs pre-assembled in the factory. (Photo: Thilo Ross)
The special reinforced concrete ceiling consists of radial sharp-edged beams. These stand out in SB 4 white concrete from the underlying ceiling in SB 2 grey concrete. (Photo: Thilo Ross)
The 11.75 m high facade supports were realised with PERI timber girder formwork and make the new HeidelbergCement headquarters particularly eye-catching. (Photo: Thilo Ross)

HeidelbergCement peakorter, Heidelberg, Saksamaa

Kõrgeim võimalik arhitektuurse betooni kvaliteet ja erakordne arhitektuur – 16 kuuga valmis ehitusmaterjalide tootja HeidelbergCement peakorter, mille ehitamisel kasutati ka PERI raketise erilahendusi.

Ülikvaliteetne arhitektuurne betoon, efektsed puude kuju meenutavad postid, kunstilised fassaadi montaaželemendid ja teravate servadega talad teevad juunis 2020 avatud hoone eriliselt silmapaistvaks.

Vaade väljastpoolt ja puukujuliste postide ehitus

11.75 m kõrged fassaadi toed SB 4 klassi arhitektuursest betoonist on tõepoolest silmapaistvad. Nende teostamiseks ja laitmatult sileda pinna saavutamiseks kasutati melamiinvaiguga kaetud puittaladest PERI raketist.  

Peakorteri 11 m fuajee keskpunkt moodustub kahest grupist puukujulistest postidest. Nende postide puhul on samamoodi kasutatud SB 4 arhitektuurset betooni. Iga post koosneb kolmest kaldelemendist, mis ristuvad alumises kolmandikus. Betoonile esitatavate nõuete, betoonisurve 200 kN/m² ja fuajee piiratud ruumi tõttu tuli puitraketise asemel kasutada spetsiaalset teraselementidest valmistatud 3D raketist.   

Betoonivalu altpoolt ja betooni surve mõõtmine reaalajas

Lisaks betooni kvaliteedile esitatavatele nõuetele, seisnes teine omapära betoonivalu meetodis. Erinevalt tavapärasest, valati betooni mitte ülevalt, vaid altpoolt. Raketisele paigaldatud PERI InSite Construction (ISC) sensorite abil mõõdeti betoonisurvet reaalajas ning protsessi jälgiti ISC äpi kaudu.

PERI kompetents

PERI inseneride ülesannete hulgas olid erilahenduste projekteerimine, objekti personali nõustamine ja õigeagsete tarnete planeerimine.
