Abstract
A beam including a web with a longitudinal center line, and the web including at least a first row of plurality of apertures, in a longitudinal direction of the beam, said first row of plurality of apertures are arranged on a first longitudinal axis parallel with the longitudinal center line. A distance between centers of adjacent apertures satisfies the following condition: Dadjacent=1000 mm/(2*n), where Dadjacent is a distance between the centers of the adjacent apertures in the first row of the plurality of the apertures and n is a natural number.

wherein D y,z is height or width or both of the beam, and n is a natural number.
2 . The beam as claimed in claim 1 , wherein the first row of the plurality of apertures is arranged at 25% of a width of the web or D adjacent /2 from the closest longitudinal edge of the beam, and the second row of the plurality of apertures is arranged at 25% of the width of the web or D adjacent /2 from the closest longitudinal edge of the beam.
3 . The beam as claimed in claim 1 , wherein the external dimension of the beam satisfies the following condition:
D x =n*D adjacent , wherein D x is length of the beam, and n is a natural number.
4 . The beam as claimed in claim 1 , wherein n is preferably 1, 2, 4, 8 or 16, and more preferably n is 2, 4 or 8.
5 . The beam as claimed in claim 1 , wherein the external dimension of the beam satisfies the following condition:
D y,z =3*1000 mm/(2*n), wherein D y,z is height and width of the beam and n is preferably 2 or 4.
6 . The beam as claimed in claim 1 , wherein the plurality of apertures of the first row and the plurality of apertures of the second row are substantially circular and having substantially identical diameter.
7 . The beam as claimed in claim 6 , wherein the diameter of the plurality of apertures of the first row and the diameter of the plurality of apertures of the second row is 26-28% of D adjacent , and preferably 27.25% of D adjacent .
8 . The beam as claimed in claim 1 , wherein the web comprises a third row of plurality of apertures on a third longitudinal axis parallel with the longitudinal center line.
9 . The beam as claimed in claim 8 , wherein the plurality of apertures of the third row are arranged between the first row of plurality of apertures and the second row of plurality of apertures, preferably at the longitudinal center line.
10 . The beam as claimed in claim 8 , wherein the plurality of apertures of the third row are substantially circular and having larger diameter than the plurality of apertures of the first row.
11 . The beam as claimed in claim 10 , wherein the diameter of the plurality of apertures of the third row is 45-70% of D adjacent , and more especially 52% or 69% of D adjacent .
12 . The beam as claimed in claim 1 , wherein the beam is shaped as I-, H-, U- or L-beam, or the beam is a hollow beam, wherein the beam comprises at least one flange comprising at least a first additional row of plurality of apertures and a second additional row of plurality of apertures, in the longitudinal direction of the beam,
said first and second additional rows of plurality of apertures are arranged on respectively first and second additional longitudinal axis parallel with the longitudinal center line, and the plurality of apertures of the first additional row and the plurality of apertures of the second additional row are perpendicularly aligned with the plurality of apertures of the first row and the plurality of apertures of the second row.
13 . The beam as claimed in claim 12 , wherein the plurality of apertures of the first additional row and the plurality of apertures of the second additional row are substantially circular and having substantially identical diameter with the plurality of apertures of the first row.
14 . A temporary structure, wherein the temporary structure comprises at least two beams as claimed in claim 1 , said beams are connected to each other with joints and/or fasteners.Join the waitlist — get patent alerts
