Detailed description of the invention
By describing technology contents of the present utility model, structural feature, the effect that realized in detail, below in conjunction with
Embodiment also coordinates accompanying drawing to be explained in detail.
As it is shown in figure 1, this utility model cage joist 100 includes floor centre gangway 101, and distribution
In floor centre gangway 101 both sides and the middle passage longeron 102 that sets gradually from inside to outside and sill strip 103,
Longitudinal floor beam 104, longitudinal floor beam 104 and sill strip it is additionally provided with between sill strip 103 and middle passage longeron 102
Fixing connection sill strip connecting plate 7, the company of fixing between longitudinal floor beam 104 and middle passage longeron 102 between 103
Connect middle passage longeron connecting plate 8.
Referring to Fig. 1 again, sill strip 103 includes sill strip leading portion 1 and sill strip back segment 2, sill strip leading portion
1 fixing with sill strip back segment 2 is connected, and sill strip leading portion 1 is connected with sill strip connecting plate 7, sill strip leading portion
The thickness of 1 is more than the thickness of sill strip back segment 2.Longitudinal floor beam 104 includes that longitudinal floor beam leading portion 3 and floor are indulged
Beam back segment 4, longitudinal floor beam leading portion 3 and longitudinal floor beam back segment 4 is fixing to be connected, longitudinal floor beam leading portion 3 with in lead to
Road longeron connecting plate 8 and sill strip connecting plate 7 are fixed.The thickness of longitudinal floor beam leading portion 3 is more than longitudinal floor beam
The thickness of back segment 4.Middle passage longeron 102 includes middle passage longitudinal beam front section 5 and middle passage longeron back segment 6, in
Passage longitudinal beam front section 5 is fixing with middle passage longeron back segment 6 to be connected, and middle passage longitudinal beam front section 5 is indulged with middle passage
Beam connecting plate 8 connects, and the thickness of middle passage longitudinal beam front section 5 is more than the thickness of middle passage longeron back segment 6.This
Sample can promote lightweight on the premise of ensureing bus body strength.Above-mentioned sill strip 103, longitudinal floor beam 104 and
The segment design of middle passage longeron 102, and leading portion thickness can be at guarantee car more than the design of back segment thickness
The lightweight of automobile is promoted on the premise of stiffness of the body degree.
The thickness of longitudinal floor beam 104 is more than the thickness of sill strip 103, and the thickness of sill strip 103 is logical in being more than
The thickness of road longeron 102.On the premise of ensureing bus body strength, the most equally promote lightweight；Meanwhile,
