摘要:
An improved prefabrication type high level road structure and a construction method thereof by which a high level road can be more easily and rapidly constructed without causing a traffic jam at the construction site of a high level road, which includes an underground section (2) for stably supporting said prefabrication type high level road structure and for effectively distributing the weight of the same to the ground; a plurality of support sections (4) spaced-apart from one another among a road on which a prefabrication type high level road is constructed and standing on said road; a pavememt section (6) formed on the upper portion of said supports (40); and a wall section (8) formed at both sides of the road and along the pavement section (6).

The invention pertains to a structural member (3) for bridges, floors, and the like which comprises at least one longitudinal girder of trapezoidal, V-shaped or U-shaped or rectangular cross section (3) with a concrete slab (6) provided thereon, wherein the longitudinal girder is made of synthetic material and at least the side parallel to the concrete slab is reinforced with parallel fibres having an embedded modulus of elasticity of more than 50 GPa. The structural member appreciably simplifies the construction of bridges and floors and has a low weight.

Außerdem betrifft die Erfindung ein Verfahren zur Herstellung eines derartigen Verbundtrogs (10)
摘要:
Prefabricated girder element comprising two spaced‑apart flat flanges connected by a vertical web made of a rectangular flat sheet, so as to configure an I‑section girder, said web having two opposite lateral faces to which are attached a plurality of transverse flats extending vertically over the entire height of the web, distributed over the entire length of the module, and separated from one another by a constant spacing corresponding to a sub‑multiple of this length, said flats each forming a stiffening rib having one vertical side welded to the web and two spaced‑apart horizontal sides welded to the mutually‑facing internal faces of the two flanges. Said element is designed to form an element that forms part of a metal bridge span. The invention also relates to a metal bridge span and to a method for the modular construction of such a span.
摘要:
A modular plastic structural composite comprises a web section disposed along a horizontal axis and at least one flange section disposed along a horizontal axis parallel thereto and integrally molded to engage the top or bottom surface of said web section, wherein said composite is formed from a co-continuous immiscible polymer blend of a high density polyolefin and a thermoplastic-coated fiber material. The modular plastic composite may for example be an I-Beam, a C-Beam or a T-Beam. In one application it may be used in a bridge constructed from I-Beams, comprising a plurality of pier-supported parallel rows of larger first I-Beams, and a plurality of smaller second I-beams disposed parallel to one another and fastened perpendicular to and between adjacent rows of the larger first I-Beams, wherein the top and bottom surfaces of the second I-Beam flanges are dimensioned to nest within the opening defined by the top and bottom flanges of the first I-Beams.
