Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described.It is practical based on this
Embodiment in novel, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, is fallen within the protection scope of the utility model.
As shown in Figure 1 and Figure 2, the present embodiment provides a kind of large span large spaces to overhang girder construction, including Cantilever Beams 2, fixation
Seat 1, Cantilever Beams 2 are two, are connected two Cantilever Beams 2 by fixing seat 1 in the middle part of Cantilever Beams 2, the one of one of Cantilever Beams 2
End is embedded in the I-shaped through-hole 6 of wall in advance.
As shown in Figure 5, Figure 6, Cantilever Beams 2 are I-shaped structure, are provided in the two sides that Cantilever Beams 2 are embedded in wall one end in advance
Clamp system 21；Clamp system 21 includes that clamping plate 211 and the second compressed spring 212, the front end of clamping plate 211 are hinged on overhanging
One end of beam 2, the end of clamping plate 211 are fixed on the side wall of Cantilever Beams 2 by the second compressed spring 212.In use, clamping plate
