Presupuesto
Losa 9 x 26.60
Área | 9 x 26.60= 239.40 m2 |
Espesor | 0.15 m |
Volumen | 239.40 m2 x 0.15 = 36m3 |
Volumen Hormigón | 36m2 x 70% = 25.2m3 25.2 X $150 = 3780 |
VCl[pic 1]
0.35 x 0.15 |
(0.325 x 2) + (0.125 x 2) + (0.10 x 2) = 1.10 corte |
26.60 x 2 =53.2 ml x 7 est/m = 372 Unidades |
372 / 10 Est = 37.2 = 38 Varillas |
38 O 8mm x 12 ml[pic 2] |
VCi[pic 3]
0.40 x 0.15 |
(0.375 x 2) + (0.125 x 2) +(0.10 x 2)= 1.00 corte |
372 / 10 Var c/u = 37.2 = 38 |
38 O 8mm x 12 ml[pic 4][pic 5] |
VA[pic 6]
0.30 x 0.15 |
(0.275 x 2) + (0.125 x 2) + (0.10 x 2) = 1.20 corte |
7 x 8.01= 56.07 ml |
56 x 6 c/u = 336 unidades |
336 / 12= 28 |
28 O 8mm x 12 ml |
Cemento
25.2 x 5.5 c/m3 = 139 sacos x $7.80 = $1085 |
Arena de río 1:2:4
0.40 x 0.40 x 0.25 x 2u x 139 sacos = 11.12 m3 |
11.12 x $ 15 c/m3 = $167 |
Piedra 3/4
0.40 x 0.40 x 0.20 x 4u x 139 sacos = 18 m3 |
17.8 x $ 18 c/m3= $321 |
Fundidores
$3 c/sacos x 139 sacos = $417 |
1085 + 167 + 321 + 417 = $1990 |
Hierro
239.40 m2 x 0.25= 59.85 c/q |
59.85 x $48= $2873 |
