Prefabricated steel bridge or viaduct structure
Abstract
A prefabricated steel bridge or viaduct structure, which is
formed essentially of three blocks fabricated and pre-assembled in
factory, and assembled together to the construction site. Once the
blocks mounted thereon the concrete pillars, a surface drain for
evacuating water is installed thereof to be casted therein a
concrete slab and after covered from asphalt with drip slope.

Claims
1. A steel bridge or viaduct structure which is formed essentially
of three blocks fabricated and pre-assembled in factory, and
assembled together to the construction site by means of joints and
bolts, wherein each block includes diaphragms assembled to angle
iron welded to beams sliding on pieces fixed thereon the concrete
pillars, wherein the beams are welded to parapet assembled to
guardrail, and once the blocks mounted thereon the concrete pillars
a surface drain for evacuating water is installed thereof to be
casted therein a concrete slab and after covered from asphalt with
drip slope.
Description

SUMMARY OF THE INVENTION
[0014] In accordance with the teachings of the present invention,
there is disclosed a steel bridge or viaduct structure which is
installed to the construction site in eight hours as opposed to the
months-long construction periods typically associated with
cast-in-place concrete bridge. The steel bridge or viaduct provides
an improved structure formed essentially of three blocks fabricated
and pre-assembled in factory, and after carried to the construction
site. Once the blocks mounted thereon the concrete pillars, a
surface drain for evacuating water is installed thereof to be
casted therein a concrete slab and after covered from asphalt with
drip slope. The foregoing and other objects, features, and
advantages of this invention will become more readily apparent from
the following detailed description of a preferred embodiment with
reference to the accompanying drawings, wherein the preferred
embodiment of the invention is shown and described, by way of
examples. As will be realized, the invention is capable of other
and different embodiments, and its several details are capable of
modifications in various obvious respects, all without departing
from the invention.
[0015] Accordingly, the drawings and description are to be regarded
as illustrative in nature, and not as restrictive.
BRIEF DESCRIPTION OF THE DRAWINGS
[0016] The accompanying drawings show illustrative embodiment of
the present invention from which the features and advantages will
be readily apparent.
[0017] FIG. 1 is an elevation view of the prefabricated bridge
incorporating the principles of the invention.
[0018] FIG. 2 is a view showing a block of the bridge
structure.
[0019] FIG. 3 is a view showing two blocks of the bridge
structure.
[0020] FIG. 4 is an isometric view of the prefabricated bridge
incorporating the principles of the invention.
[0021] FIG. 5 is a cut view of the prefabricated bridge
incorporating the principles of the invention.
[0022] FIG. 6 is a view showing the three blocks disassembled.
[0023] FIG. 7 is an enlarged view of the prefabricated bridge
incorporating the principles of the invention.
DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
[0024] According to the embodiment of the present invention, as
depicted in FIGS. 1 to 7, it is shown the steel bridge or viaduct
structure which is formed essentially of three blocks fabricated
and pre-assembled in factory, and assembled together to the
construction site by means of joints (4) and bolts (11). Each block
is formed of diaphragms (3) assembled to angle iron (14) welded to
beams (8,9) sliding on pieces (7) fixed thereon the concrete
pillars (6). The beams (8) are welded to parapet (5) assembled to
guardrail (1). Once the blocks mounted thereon the concrete pillars
(6), a surface drain (10) for evacuating water is installed thereof
to be casted therein a concrete slab (2) and after covered from
asphalt (12) with drip slope (13).
[0025] Each block weighs approximately sixty tons and is five feet
height, three feet width, and a hundred fifteen feet length. For
the two-track roads it is necessary to install several blocks in
the middle so as to obtain the desired width.
[0026] This new concept would particularly advantageous in the
construction on-site of mega interchange which is be very
complicated and extremely dangerous for the safety of workers on
the construction site and the drivers circulating on the roads.
[0027] Although only a single embodiment of the present invention
has been described and illustrated, the present invention is not
limited to the features of this embodiment, but includes all
variations and modifications within the scope of claims.
