Abstract

The utility model discloses an escalator, in particular to an escalator truss girder, which comprises an upper chord, a lower chord, a vertical rod perpendicular to the upper and lower chord and a diagonal web member diagonal with the upper and lower chord and is characterized in that the upper and lower chord is made from square steel tube. The vertical rod and diagonal web member are made from angle steels, wherein the upper chord and the lower chord are connected with the vertical rod and diagonal web member through gussets. A horizontal mudsill and a diagonal mudsill are arranged on the lower chord. The horizontal mudsill and diagonal mudsill are made from channel steel. The utility model has the advantages of reducing cost and improving strength, rigidness and stability.

Description

Staircase and girder

Technical field

The utility model relates to a kind of escalator, especially a kind of staircase and girder.

Background technology

The truss of escalator is the support component of whole staircase, the frame mode of existing truss roughly has two kinds: a kind ofly be the square tube truss, no matter be upper and lower chord member, or montant, diagonal web member all adopt the square tube section bar, the mechanical property excellence of this structure truss, but productive costs is higher relatively; Another kind is a truss of angle steel, and its upper and lower chord member and montant, diagonal web member all adopt angle steel, and this structure truss cost is relatively low, but compares with the truss that adopts the square tube section bar, and its mechanical property is relatively poor.Therefore the merits and faults of existing structure truss is all more obvious, the also still incompetent up to now truss structure in conjunction with both advantages.

As Chinese invention patent application 200520072503.6 disclosed " moving staircase girders ", comprise the top truss, be fixedly connected on top truss downside the middle part truss, be fixedly connected on the bottom truss of middle part truss downside, the shape of its structure and used section bar is all different with the utility model.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of not only cost-cutting, but also improves the staircase and girder of intensity, rigidity and stability.

The utility model addresses the above problem, the technical scheme that is adopted is: this staircase and girder comprises the staircase and girder parts, its constructional feature is that described upper and lower chord member adopts the square tube section bar, montant perpendicular to upper and lower chord member adopts angle steel with the diagonal web member that favours upper and lower chord member, captive joint by gusset plate between upper and lower chord member and montant, the diagonal web member, above bottom girder, be provided with some interconnected zincing steel sheets, and the bending edges on zincing steel sheet both sides is fixed on the lower boom inboard.

Bottom girder described in the utility model comprises horizontal bottom girder and the beam that tiltedly undercuts, and laterally the bottom girder and the beam that tiltedly undercuts are fixedly connected on the lower boom, and horizontal bottom girder and the beam that tiltedly undercuts employing formed channel steel.Described zincing steel sheet is bent into echelon form, and successively after junction stack, is connected to each other by rivet.Pass through the gusset plate weld together between described upper and lower chord member and montant, the diagonal web member.The bending edges on described zincing steel sheet both sides is welded to the inboard of lower boom.

The utility model compared with prior art, has following beneficial effect: 1, by labor to existing truss stressing conditions, utilize square tube and angle steel advantage separately, positions different on the same truss are adopted different structures respectively, and existing truss is fully optimized; Because the bulk strength of truss, rigidity and stability depend primarily on the upper and lower chord member of truss, therefore upper and lower chord member adopts the square tube section bar, compares with angle steel, has improved the whole mechanical property of truss greatly; Montant on the truss and diagonal web member then adopt angle steel, are satisfying under the prerequisite of requirement of strength, greatly reduce the truss cost.2, adopt horizontal bottom girder, tiltedly undercut beam and zincing steel sheet as the truss base plate, so both improved the stability of truss integral, can be used as drip catcher again.

The specific embodiment

Referring to Fig. 1, Fig. 2, present embodiment comprises upper and

lower chord member

1,5, perpendicular to the montant 4 of upper and

lower chord member

1,5, favour the diagonal web member 3 of upper and

lower chord member

1,5, upper and

lower chord member

1,5 adopts the square tube section bar, montant 4 and diagonal web member 3 adopt angle steel, pass through gusset plate 2 weld togethers between upper and

lower chord member

1,5 and montant 4, the diagonal web member 3.

Referring to Fig. 3-Fig. 8, between two groups of lower booms 5, be welded with the horizontal bottom girder 6 and the beam 7 that tiltedly undercuts, laterally bottom girder 6 is perpendicular to lower boom 5, and the beam 7 that tiltedly undercuts favours lower boom 5, and the horizontal bottom girder 6 and the beam 7 employing formed channel steels that tiltedly undercut.Some thickness are that the zincing steel sheet 8 of 1mm is bent into echelon form, and superpose mutually in the junction successively, during stack the minor face of a zincing steel sheet 8 is inserted the inside, long limit of another piece zincing steel sheet 8, by some rivets 9 two zincing steel sheets 8 are coupled together then, after in this way all zincing steel sheets 8 being coupled together it is positioned over horizontal bottom girder 6 and beam 7 tops that tiltedly undercut, the bending edges 8-1 on zincing steel sheet 8 both sides is welded to the inboard of lower boom 5.
