Description
Beam bedding junction, cross beam and truss span for bridge and/or similar structures
Field of technology
The invention relates to a beam bedding junction, a cross beam provided at its ends by beam bedding junctions and to a truss span comprising a cross beam, the first ends of truss beams of a bridge and/or similar structure being attached to the beam bedding junctions of the cross beam.
State of art
Different types of junction gussets for truss and similar space structures are known in present times.
Simplest junction gussets are formed by one single slab, ends of individual beams and of truss members being riveted, screwed or welded to the slab.
Junction gussets are used in many structures, the gussets having a form of the letter U in their cross section. These junction gussets are connected to longitudinal beams so that pertinent ends of truss members can be screwed or riveted to parallel portions of the longitudinal beams.
Junction gussets are known from the document WO
94/15041\ (Fig.76) , said gussets consisting from two individual, parallel arranged slab members, each of them being attached by screws or rivets to one side of the beam.
Pertinent ends of further beams or truss members are then screwed or riveted to the portions of these slab members which project over the circumference of the beam.
High requirements concerning the production accuracy are disadvantageous in respect to many known junction gussets and
also to beams and truss members which are attached to the junction gussets, this fact leading consequently to higher prices of whole said structures.
Subject matter of invention
Above mentioned insufficiencies of known junction members are removed by the beam bedding junction for connecting cross beams to longitudinal junction chords and truss members of bridge and/or similar structures according to the invention, the subject matter of which consisting in the fact that they are comprised of two parallel arranged slabs fixed mutually by means of one vertical connecting member, this member being formed by a cross girder or beam, more particularly a central cross girder or beam, a normal distance between inner surfaces of the slabs corresponding to one transversal size of longitudinal junction chords and truss members.
Also another fact is substantial for the beam bedding junction, this fact consisting in the advantage that the beam bedding junction is by its lower side connectable to a bearing bed of the bridge and/or similar structure, the beam bedding junction being connectable by the side directed to the cross beam to one end of at least one longitudinal kerb, this arrangement being designed to limit a transport corridor. The invention consists further in a cross beam for bridge and/or similar structure, the subject matter of which being the fact that at least one mentioned beam bedding junction is attached in a separable or inseparable way to each end of the cross beam by means of an outer surface of one of theirs slabs.
It is necessary to hold for the invention also a truss span for bridge and/or similar structures, its subject matter consisting in the fact that the truss span is comprised of the said cross beam, whereby at least the first ends of truss
members, on the one hand, and one and of the longitudinal junction chord, on the another hand, are attached in a separable or inseparable way to each of said beam bedding junctions .
The beam bedding junction associates advantageously the pertinent bearing portions of a bridge and/or similar structure, such a structure being the only one representing an element which involves higher requirements concerning its creation.
All other structural parts are very simple so that it is possible to produce them in series and therefore cheaply.
The association of bearing parts into beam bedding junctions brings also a minimum possibility of errors and a quick production and assemblage, no expert for such structures being necessary.
Also assembling times for the production of such desired structure are fundamentally shorter by the creation of whole truss spans and by their transport.
Summary of drawings
The attached drawings comprise examples of embodiments of said structural elements of this invention, in which:

Examples of inventive embodiments
A beam bedding junction jS (Fig.l) for connecting cross beams 1_ with longitudinal junction chords _3 and truss members _4 for bridge and/or similar structures consists of two parallel arranged slabs _1 which are together firmly attached by means of one vertical connecting member, which is, in an advantageous embodiment, a central cross girder 2_. A normal distance between inner surfaces of slabs 1_ corresponds to one transversal size of attached longitudinal junction chords 3_ and truss members 4_. Inner surfaces of slabs 1_ form so attaching surfaces for the ends of connected longitudinal junction chords _3 and truss members 4_, which can be connected to the slabs _1 or~ beam bedding junctions _6 by means of screws, by welding, by an adhesive or by other separable or inseparable connecting technologies. Each beam bedding junction _6 is advantageously connectable at its lower side with a bearing bed _5 of the bridge and/or similar structure (see Fig.4) and is connectable, at the side directed to the cross beam 1_, with one end of at least one longitudinal kerb 8_ for limitation of a transport corridor ^9. The cross beam 1_ (Fig.2) for bridge and/or similar structures consists of a profiled beam, in this example of embodiment having a form of a letter I, to each its end one mentioned beam bedding junction β_ is attached by welding, this being executed by one outer surface of one of its slabs _1. The cross beam 1_ can have, in the cross section, also another form and the beam bedding junctions _6 can be attached to it also by another inseparable or separable connecting technologies. If a greater carrying capacity of the truss bridge and/or similar construction is necessary, more beam bedding
junctions _6 can be attached together at the ends of the cross beam 7_, e.g. two beam bedding junctions §_, this situation being shown e.g. in Fig.6. Thereby a construction mode for multiple truss walls of a bridge and/or similar structure is made possible.
A truss span for bridge and/or similar structures (expressively shown in Fig.3) consists then of said cross beam 1_, to each of its beam bedding junctions _6 the first ends of truss members _£, on the one hand, are separably or inseparably attached (in the shown exemplary embodiment of three truss members A) and, on the other hand, one end of one longitudinal junction chord 3_. By a mutual connection of so formed truss spans, a bridge and/or similar structure can be simply created with the aid of further horizontal and diagonal truss members 4_, of two closing cross beams 1_ and of two terminal longitudinal junction chords _3, this being possible with truss walls directed either upwards (Fig.6) or downwards (not shown) .
