STRUCTURAL ELEMENT Filed June 14, 1959 v By atla weya" Patented Jan. 27, 1942 UNITED STATES PATENT OFFICE Application June 14, 1939, Serial No. 279,221 In Germany June 16,1937
8 Claims.
This invention relates to structural elements of colfered, box-like, or cellular construction, that is, formed with open-mouthed box like recesses or spaces which are closed by assembling a plurality of the elements in contact with each other and with opposing coffers or cells in register, the closed spaces thus formed being filled with concrete or cement to unite the elements.
An object of the invention is to provide coffered structural elements applicable to a wide range of constructions.
Another object of the invention is to provide such elements with coffers of standardised form enabling the elements to be assembled in transverse as well as in parallel relation.
The structural elements according to the invention are of substantially rectangular cross section, of width exceeding th depth, and coffers or cells may be provided in both of the narrow sides of the element corresponding to the depth dimension. One of the wider sides of the element may be continuous and fiat whil the other side presents the openings of the middle or main coffers of the element.
The coffers are separated by ribs which may have thin portions formed in them to facilitate the breaking through of openings for the passage of reinforcing members and pouring of cement.
The drawing shows a perspective View of a structural element.
The structural element is a box girder with middle and side cofiers or cellular spaces.
The fiat thin web which forms the base of the middle box like compartments or coffers I and the level under surface of th structural element is marked l9. Each of the sides 5 of the structural element has upper and lower flanges 2 and 3 in which are embedded longitudinal reinforcing irons 20, said flanges equally being connected by a web portion I l. The inner surfaces of the sides 5 of the middle coffers are inclined inwardly and downwardly.
The web portions H separate the middle coffers and the side coffers, ribs l2 are provided between the middle coffers and ribs l3 between the side coffers. Ridges l4 extend outwardly from the longitudinal flanges 2 and 3 to form the upper and lower boundaries of the side coffers, and the spacing ribs l3 extend across from the upper to the lower ridges. The outer surfaces of the ribs l3 and ridges l4 lie in one and the same plane.
Rectangular recesses l2 are provided in the ribs l2 between the middle coffers indicated by 9, and recesses l between the middle and side coffers. The walls 1 of the ribs [2 are arranged girder of substantially rectangular form in cross section the width being greater than the depth, said element comprising side portions, a bottom portion connecting said side walls, a plurality of uniformly spaced webs extending transversely from one side portion of the element to the other side portion to form a series of middle coffers,
in said element, external ridge extending longitudinally along at least one of said side portions at the top and bottom thereof and forming a longitudinal channel in said side portion and a plurality of uniformly spaced ribs extending across said side portion fromridge to ridge and dividing said channel into side colfers.
2. A structural element according to claim 1, in which the base surface of the bottom portion is planar.
3. Structural element consisting of a boxgirder like structure of greater width than depth with middle coffers in one broad side, and side coffers in both narrow sides of the element, said side coffers and middle coffers being of equal dimensions measured longitudinally of the element.
4. Structural element according to claim 3 in which each middle coffer has two opposite inner walls substantially planar and with an equal and opposite inclination to one another.
5. A structural element according to claim 1 in which the base surface of the bottom portion is planar and the edge of the ridges and ribs defining the coffers in a side portion lie in one sides of the structure.
