Detailed Description

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

A truss girder staggered through connection node is shown in figures 1 to 7 and comprises a first truss girder 1, a second truss girder 2, a locking member 3, a plurality of adjusting rods 4 and a supporting plate 5.

Referring to fig. 1 and 6, the first truss girder 1 includes four first chords 101, the first chords 101 are connected to form a truss structure by first web members 102, and a first plate 103 is fixedly disposed on the four first chords 101. Preferably, referring to fig. 7 in combination, the first chord 101 and the first plate 103 are connected by planing and jacking, and the connection strength of the two is higher.

Referring to fig. 2 and 6, the second truss girder 2 includes four second chords 201, the second chords 201 are connected to form a truss structure through second web members 202, and a second plate 203 is fixedly disposed on the four second chords 201. Preferably, referring to fig. 7 in combination, the second chord 201 and the second plate 203 are connected by planing and jacking, and the connection strength of the two is higher.
