Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, embodiment of the present invention rail vehicle slope underframe interior structure, the wooden floor assembly 2 there is the base 1 being fixed on ferrum floor, being fixed on base 1 by self tapping wood screw 4.As it is shown in figure 1, base 1 has the horizontal flank of inclined support surface and two perforates, ferrum floor 5 being welded with the stud of cooperation, this horizontal flank is fixed on ferrum floor 5 by nut 3.Wooden floor assembly 2 has tilting section 21 and horizontal segment 22.The tilting section 21 of wooden floor assembly 2 is supported by this supporting surface, is lined with rubber blanket between supporting surface and tilting section 21 lower surface of wooden floor assembly 2 of base 1.Horizontal segment 22 is then fixed by self tapping wood screw 4 with vehicle floor beam, is also lined with rubber blanket between horizontal segment 22 and the vehicle floor beam 6 of wooden floor assembly 2.Tilting section 21 end of wooden floor assembly 2 connects with the threshold of sliding door position, is filled with wedge at the gap between end and the ferrum floor of tilting section 21；Horizontal segment 22 end connects with laterally adjacent vehicle byatt floor (being not drawn in figure).As shown in Figure 2,3, tilting section 21 both sides of wooden floor assembly 2 are provided with the end plate 7 carrying outer flanging, the facade of end plate 7 is fixed by countersunk head wood screw 8 with wooden floor assembly tilting section side, is fixed by countersunk head wood screw between outer flanging and longitudinally adjacent vehicle byatt floor (for drawing in figure).
The installation steps of the present embodiment slope underframe interior structure are as follows:
1st step, on ferrum floor 5 welding for the stud of firm banking 1；
2nd step, end plate 7 is fixed on by countersunk head wood screw 8 both sides of wooden floor assembly 2 tilting section 21；
3rd step, being fallen on base 1 by wooden floor assembly 2 and position, making the threshold in tilting section 21 end of wooden floor assembly 2 with sliding door position connect, horizontal segment 22 end connects with laterally adjacent vehicle byatt floor (being not drawn in figure)；
The tilting section 21 of wooden floor assembly 2 is fixed on base by the 4th step, use self tapping wood screw 4, and horizontal segment 22 is fixed on joist 6；
The 5th step byatt floor (in figure be not drawn into) longitudinally adjacent with wooden floor assembly 2 tilting section 21 is fixed by the outer flanging of countersunk head wood screw with end plate 7, thus realizes the connection between wooden floor assembly and longitudinally adjacent byatt floor.
Inclined support surface upper surface and the joist upper surface of base are fixed with rubber blanket the most in advance, play good damping effect.The tilting section end lower surface of wooden floor assembly is fixed with wedge the most in advance, has the gap filled between tilting section end and ferrum floor, improves place's timber floor intensity of entering.
Visible, the installation of interior structure of the present invention is simple, and production efficiency is high and quality is good.
In addition to the implementation, the present invention can also have other embodiments.The technical scheme that all employing equivalents or equivalent transformation are formed, all falls within the protection domain of application claims.
