Raudbetoontalad

 

Raudbetoontalade ja pingebetoontalade mõõdud ja kujud

We manufacture precast concrete beams with the following cross-sections:

Beams with rectangular cross-section
width 3M, 4M, 5M, 6M, 7M
height 5M, 6M, 7M, 8M, 9M, 10M, 11M, 12M
Modular measurement M is 100 mm. In the case of different dimensions, the conditions for manufacturing the beams must be specified.
Soovitatavad ristlõike mõõdud on 400×600, 400×700, 400×800.

Ledge beams
width 3M, 4M, 5M, 6M, 7M
height 5M, 6M, 7M, 8M, 9M, 10M, 11M, 12M

Low height prestressed beams (see also TEMPO substructure ET-3 0202-0073)
width 550, 650 (1-ledge beam width in the lower surface)
700, 800 (2-ledge beam width in the lower surface)
height 415 (EP5/265), 470 (EP4/320), 550 (EP4/400)
Ledge height 150 mm

I beams
flange width 3M, 4M, 5M

I beams load diagram:

HI beams ( I beams with ridge)
flange pitch 1:16
flange width 3M, 4M, 5M
The corners of the mould are 15x15 mm
