Embodiment Construction
[0066] The present invention is described in detail below in conjunction with accompanying drawing:
[0067] as attached figure 1 As shown, the splicing position of the assembled truss plate of the present invention is set in the middle of the main girder, where the shear force and bending moment are relatively small. From the perspective of structural mechanics, the setting of the splicing position is reasonable.
[0068] as attached figure 2 As shown, in the prestressed central support system of the prefabricated steel structure of the present invention, the involved beams are truss beams composed of angle steel splicing, including upper and lower chords I (1) and webs I (2), wherein the upper and lower chords Rod I (1) and web I (2) are both made of angle steel, and are divided into single-angle steel beams and double-angle steel beams. The single-angle steel beams are provided with connecting holes at regular intervals, which is convenient for bolts to be used when splicin...
