Problems solved by technology

The traditional truss has only two truss single pieces, and the strengthening method is to increase the thickness of the inclined section of the truss only in the height direction. When the span is further increased, more construction space is required, and the lateral stiffness and stability of the truss cannot be achieved. Guaranteed

Embodiment 1

[0020] Embodiment 1: As shown in Figure 1 and Figure 2, a large-span escalator truss includes a truss single piece, which consists of four truss single pieces, namely, the left outer single piece 1, the left inner single piece 2, and the right inner single piece 3 and right outer monolithic 4 constitute. The left outer single piece 1 and the left inner single piece 2 are closely connected together by bolts, and the right inner single piece 3 and the right outer single piece 4 are closely connected together by bolts.

[0021] In the present invention, two truss monoliths are added on the outside, and the size in the width direction only needs to be slightly increased, so that the strength can be greatly improved, and at the same time, the thickness of the inclined part of the monolith can be increased to meet the needs of large-span escalators without intermediate support , to ensure the lateral rigidity and stability of the truss, enhance the safety of the escalator, and save ...

Embodiment 2

[0024] Embodiment 2: This embodiment is a long-span escalator truss. The difference between it and Embodiment 1 is that, as shown in Figure 4, the left outer single piece 1 and the left inner single piece 2 are closely connected together by welding , the right inner single piece 3 and the right outer single piece 3 are tightly connected together by welding.

Embodiment 3

[0025] Embodiment 3: This embodiment is a large-span escalator, which has the truss described in Embodiment 1, including a truss monolith, consisting of four truss monoliths, namely the left outer monolith 1, the left inner monolith 2, Right inner single piece 3 and right outer single piece 4 constitute. The left outer single piece 1 and the left inner single piece 2 are closely connected together by bolts, and the right inner single piece 3 and the right outer single piece 4 are closely connected together by bolts.

[0026] The upper chord 5 and the lower chord 6 of the truss single piece, that is, the left outer single piece 1, the left inner single piece 2, the right inner single piece 3 and the right outer single piece 4 adopt square tubes or angle steel, and the vertical rod 7 and the oblique Bar 8 adopts square tube or angle steel or channel steel. The truss pieces on the left and right sides are welded and connected by the beam and the back cover plate in the tradition...

Abstract

The invention discloses a wide-span escalator girder, comprising a girder uniwafer. The escalator girder composed of four girder uniwafers of a left outer uniwafer (1), a left inner uniwafer (2), a right inner uniwafer (3) and a right outer uniwafer (4), wherein, the left outer uniwafer (1) and the left inner uniwafer (2) are connected closely by adopting a bolt or a welding way, the right inner uniwafer (3) and the right outer uniwafer (4) are connected closely by a bolt or a welding way; an upper chord member (5) and a lower chord member (6) of the girder uniwafers adopt square tubes or angle iron, a vertical bar (7) and a diagonal rod (8) of the girder uniwafers adopt square tubes or angle iron or channel steel. The invention also discloses a wide-span escalator provided with the girder. The girder of the wide-span escalator of the invention is reinforced in both the height direction and the transverse direction, thereby satisfying the requirements of the non intermediate support of the wide-span escalator, guaranteeing the transverse rigidity and stability of the girder, improving the security of the escalator and saving building space.

Description

technical field [0001] The invention relates to a large-span escalator truss and a large-span escalator without intermediate support. The escalator truss is a supporting structure for an escalator or a moving walk. Background technique [0002] In the prior art, when the span of the escalator exceeds a certain value, the stiffness of the truss cannot meet the requirements of the standard, and it is generally necessary to add intermediate supports or strengthen them. When it is impossible to increase the intermediate support due to structural reasons, strengthening the truss is the only way. The traditional truss has only two truss single pieces, and the strengthening method is to increase the thickness of the inclined section of the truss only in the height direction. When the span is further increased, more construction space is required, and the lateral stiffness and stability of the truss cannot be achieved. Guaranteed. Contents of the invention [0003] The purpose o...
