Definitions
- Lattice girder in particular for forming a railing carrying a suspended gangway
- the invention relates to lattice girders which consist of elements rigidly connected to one another in order to produce structures capable of carrying loads.
- Such truss beams are known, the constituent elements of which are arranged according to the orientation of the loads to be supported and their distribution. These elements are generally linked together by welding.
- One of the applications of these structures is to form railings carrying a gangway and in particular a suspended gangway in order to connect the load of a floor to connecting or suspension stirrups.
- the object of the present invention is to produce such truss-beam structures, in particular for forming gangway railings, by means of seamless assemblies.
- the welding technique has bothersome and costly consequences.
- the welding operation results in an annealing effect on the area concerned partially but notably neutralizing the improvement in elastic limit obtained by heat treatment of the quality of aluminum used for this purpose.
- any weld increases the risk of corrosion and requires, to limit these risks, a strict and costly quality control procedure, to which is added the cost of qualified personnel.
- the truss-beam structure according to the invention which is constituted by an assembly of elements linked together by the embedding of projecting parts of one into parts forming receptive housings of the other, is characterized in that that its structural elements consist only of homogeneous hollow profiles having cutouts intended to achieve by embedding connections by which the embedded parts are self-locking laterally with the parts which receive them.
- the assemblies according to the invention are thus produced so as to meet the load constraints which are applied to them in force and in direction, by ensuring a rigid connection of the components.
- the assemblies according to the invention are variably configured according to the assembly angles, the right angle assembly being only one application case.
- the receiving elements of the recessed parts of the other elements consist of two half-elements applied longitudinally against each other and made integral by means of appropriate connection, so that the embedded parts can be introduced before assembly of the two half-elements in the corresponding openings thereof and, after assembly of the said half-elements, lock therein longitudinally by cuts made on two parallel sides embedded parts at an angle with the axis of each embedded element corresponding to the axis of assembly of the latter with the receiving element, the section of the embedded part being dimensioned for this purpose.
- the connecting means integrating the two half-elements of each spar is produced by a hooking structure integrated into each half-spar member, the two hanging structures being made face and corresponding to each other so as to make the two half-elements integral by a pressure action of one against the other.
- the beam produced according to the invention by the above-mentioned assemblies can be provided with vertical end jambs making it possible to fix it on a gangway floor module so as to form a gangway or a gangway module.
- an assembly formula can be produced according to which the horizontal beams of the beam receive at each of their ends a notched extension to receive, by vertical engagement, an amount at least partially open, the lower part of which, after installation. , is fixed to a floor structure element in order to make a gangway or a gangway module.
- FIG. 1 shows an example of a truss made according to invention
- Figures 2 and 3 show examples of assembly according to the invention of two elements of a lattice beam
- Figures 4 and 5 show, respectively before and after assembly, the self-locking connection mode according to the invention of a beam made of two half-elements and an oblique cross
- Figure 6 shows a variant of the truss of Figure 1, having at its ends assembly grooves to the railing uprights
- Figure 7 is a detail view of one end of the beam of Figure 6
- Figure 8 shows the final assembly of the beam of Figures 6 and 7 to form the railing of a suspended walkway.
- FIG. 1 there is shown a simple assembly of a truss beam formed in a plane and produced according to the invention.
- This beam comprises upper 1 and lower 2 beams, vertical end uprights 3, 4 and oblique crosspieces 5, 6, 7, 8, all of these elements being formed by homogeneous hollow profiles which are rigidly assembled by embedding, without requiring other load-bearing connecting means such as welds.
- FIG. 2 shows an example of such an assembly method, according to the invention, of a spar 9 and a vertical upright 10.
- the upright 10 partially open, has a notch 11 in which engages the notched end of the side member 9.
- FIG. 3 shows a more advantageous embodiment of the assembly according to the invention, the spar 12 being produced from two half-profiles 13,14 comprising assembly windows 15,16, these half-profiles being joined together one against the other longitudinally after insertion, in said windows, of the corresponding end of the upright 17.
- FIGS. 4 and 5 show an improvement in the mounting conditions by joining two half-profiles.
- the two half-profiles 18,19 intended to constitute a spar are internally provided with longitudinal tongues with transverse notches 20,21 which allow, by pressure, to apply the half-profiles against each other and to secure them definitively to form a single profile.
- FIG. 4 shows in particular the half-profiles 18, 19 separated to allow the introduction, into their windows 22, 23 facing each other, of the end of an oblique crosspiece 24 entailed at 25 and 26.
- FIG. 6 to 8 show a beam 1 according to the invention intended to serve as a railing for a suspended gangway, and designed for this purpose to assemble to a floor of such a gangway and a suspension bracket.
- the beams 27 of the beam have at each end an extension 28 which comprises two lateral notches 29 (see FIG. 7).
- a tubular upright 30 slides vertically, having a partially or completely open side, which, as shown in FIG. 8, is fixed by screwing to a floor structure 31 of the gangway shown in dotted lines.
- each of the half-profiles 18, 19 intended to constitute a spar has externally opposite parts 32 forming slides which allow a plate to be fitted between these two parts by sliding (not shown in the drawing). ) bearing inscriptions or serving as a support for accessories.
