Referring to fig. 4, the tie bars 3 of the present utility model, which are generally referred to as rod-like structures in a horizontal state in a roof construction, are used to connect between two truss girders 1, fixing the distance between the two truss girders 1.

The tie bar connecting portion 21 is connected to the side of the truss girder connecting portion 22 and is connected perpendicularly to the truss girder 1, so that the tie bar 3 can be vertically installed to the side of the truss girder 1 when the tie bar 3 is connected to the truss girder 1 through the connection node 2.
The tie bar connecting portion 21 includes an overhanging plate 211 connected to a side of the truss girder connecting portion 22 and a limiting plate 212 for limiting the tie bar 3. The cantilever plate 211 has one end connected to the side plate of the truss girder connection portion 22 and is connected at or near the lower end of the side plate, so that the truss girder connection portion 22 laterally forms an extension structure for connecting the tie bars 3.

Based on the setting of the limiting plate 212, the problem that the horizontal tie rod 3 is difficult to be placed into the connecting piece because the existing rectangular limiting plate 212 is easy to deform inwards and the deformation can be accumulated in the connecting welding process can be solved.
Preferably, the limiting plate 212 has a bevel edge, and one side surface can be a plane or a surface with radian.
Preferably, the tie bar connecting parts 21 are provided with two tie bar connecting parts 21 respectively provided on opposite sides of the truss girder connecting part 22, which can apply a force to the tie bar connecting part 21 to bring the tie bar connecting part 21 close to the truss girder connecting part 22 by the gravity action of the horizontally provided tie bars 3 when the tie bars 3 are mounted on the tie bar connecting part 21, so that the truss girder connecting part 22 is forced to clamp the truss girder 1.
Specifically, the top of the truss girder 1 is a flat structure, the U-shaped truss girder connecting portion 22 is pressed into the top of the truss girder 1 during installation, at this time, the horizontal tie bars 3 act on the tie bar connecting portion 21 under the action of gravity, so that the U-shaped truss girder connecting portion 22 deforms, the tie bar connecting portions 21 are arranged on two sides of the truss girder connecting portion 22 to connect the tie bars 3, and the horizontal tie bars 3 on two sides convert the acting force (namely the bending moment of the tie bars 3) generated during bending deformation under the action of gravity into the pressing force of the U-shaped truss girder connecting portion 22 to the inside of the vertical web member 12, and the U-shaped truss girder connecting portion 22 can lock the vertical web member 12.
