Through the technical scheme, the occupied area of the truss can be effectively saved through the outward turning chord, and the space is saved.

Lie in two with one side the horizontal direction fixedly connected with a plurality of evenly distributed's montant in proper order between the chord member turns up, lie in two with one side lie in the diagonal member that fixedly connected with slope set up between a plurality of montants between the chord member turns up, it is a plurality of the montant is perpendicular with the chord member that turns up.

The utility model discloses it is further set up to, two sets of be provided with four tip support piece between the bracing piece, four tip support piece and the chord member fixed connection that turns up that corresponds the position.

The utility model discloses further set up to, two tip support piece that are located the top are close to the chord member center one side position that turns up and all are provided with the round pin fixed plate that lifts by crane that two symmetries set up.

The utility model discloses further set up to, two it has the lifting pin to lift by crane through threaded connection between round pin fixed plate and the tip support piece, and lifts by crane through lifting pin fixed connection between round pin fixed plate and the tip support piece.

The utility model discloses further set up to, be located the inboard fixed position of montant of chord member both ends position of turning up and be connected with the main shaft backup pad.

The utility model discloses it is further set up to, is located a plurality of middle part position fixedly connected with horizontal pole between the montant.

The utility model discloses it is further set up to, a plurality of montant outside position fixedly connected with lower part guide rail turns to the device backup pad.

The utility model has the advantages as follows:

the utility model discloses a chord member turns up adopts the angle steel structure of outside connection to set up montant and down tube in the chord member outside turning up outward, make under the condition of guaranteeing truss intensity, reduce area occupied, be adapted to the more narrow special building in specific area's building structure's space.

In the figure: 1. an everting chord; 2. an end support; 3. lifting pin fixing plates; 4. lifting the lifting pin; 5. A diagonal bar; 6. a lower guideway steering apparatus support plate; 7. a main shaft support plate; 8. a cross bar; 9. a vertical rod.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

The first embodiment is as follows: referring to fig. 1 and 2, a truss structure for an escalator includes two sets of symmetrically disposed support rods, four end support members 2 are disposed between the two sets of support rods, two symmetrically disposed lifting pin fixing plates 3 are disposed at positions of the two end support members 2 above the two sets of support rods, which are close to a center of an outward turning chord 1, and an oblique rod 5 and a vertical rod 9 are disposed at outer sides of the outward turning chord 1.
