In order to solve above technical matters, guideway vehicle slope provided by the invention underframe interior structure, it is characterized in that: there is the base be fixed on iron floor, be fixed on the wooden floor assembly on base, described base has the bearing surface of inclination, described wooden floor assembly has tilting section and horizontal segment, the tilting section of wooden floor assembly supports by this bearing surface, horizontal segment is then fixed with vehicle floor beam, the tilting section end of wooden floor assembly connects with the threshold of sliding door position, the end of horizontal segment connects with laterally adjacent vehicle byatt floor, the tilting section both sides of described wooden floor assembly are provided with the end plate being with outer flanging, facade and the wooden floor assembly tilting section side of end plate are fixed by screw, outer flanging is fixed by screw with longitudinally adjacent vehicle byatt floor.
In order to solve the problem, the present invention also has following further feature:
1, described base has the horizontal flank of two perforates, iron floor is welded with the stud of cooperation, and this horizontal flank is fixed on iron floor by nut.
2, rubber pad is provided with between the bearing surface of described base and the tilting section lower surface of wooden floor assembly.
3, rubber pad is provided with between described vehicle floor beam and the horizontal segment of wooden floor assembly.
4, the gap place between the end of described wooden floor assembly tilting section and iron floor is filled with wedge.
5, fixed by self tapping screw nail between described wooden floor assembly and base, floor bearer.
6, described wooden floor assembly is equipped with floor cloth.
Base of the present invention is connected with steel structure of car body, ensures integrally-built stable, top wood floors and horizontal floor slitless connection; Car load underframe is in-built without diff-H, and car load floor is horizontal positioned.
Slope of the present invention underframe interior structure is installed at car door place, while ensureing the reliable and function of underframe interior structure, improve car door by height, appearance looks elegant is generous, and it is convenient to install, and improves safety and traveling comfort that passenger rides.

Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, embodiment of the present invention guideway vehicle slope underframe interior structure, has the base 1 be fixed on iron floor, a wooden floor assembly 2 be fixed on by self tapping screw nail 4 on base 1.As shown in Figure 1, base 1 has the horizontal flank of inclined support surface and two perforates, iron floor 5 is welded with the stud of cooperation, and this horizontal flank is fixed on iron 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 supports by this bearing surface, is lined with rubber pad between the bearing surface of base 1 and tilting section 21 lower surface of wooden floor assembly 2.Horizontal segment 22 is fixed by self tapping screw nail 4 with vehicle floor beam, is also lined with rubber pad between the horizontal segment 22 of wooden floor assembly 2 and vehicle floor beam 6.Tilting section 21 end of wooden floor assembly 2 connects with the threshold of sliding door position, and the gap place between the end of tilting section 21 and iron floor is filled with wedge; Horizontal segment 22 end connects with laterally adjacent vehicle byatt floor (not shown in FIG.).As shown in Figure 2,3, tilting section 21 both sides of wooden floor assembly 2 are provided with the end plate 7 being with outer flanging, the facade of end plate 7 and wooden floor assembly tilting section side are fixed by countersunk head screw nail 8, are fixed between outer flanging and longitudinally adjacent vehicle byatt floor (for drawing in figure) by countersunk head screw nail.
The installation steps of the present embodiment slope underframe interior structure are as follows:
1st step, on iron floor 5 welding be used for the stud of firm banking 1;
2nd step, end plate 7 is fixed on the both sides of wooden floor assembly 2 tilting section 21 by countersunk head screw nail 8;
3rd step, being dropped on by wooden floor assembly 2 on base 1 and locate, the threshold in tilting section 21 end of wooden floor assembly 2 with sliding door position is connected, the vehicle byatt floor (not shown in FIG.) adjacent with transverse direction, horizontal segment 22 end connects;
The tilting section 21 of wooden floor assembly 2 is fixed on base by the 4th step, use self tapping screw nail 4, and horizontal segment 22 is fixed on floor bearer 6;
5th step, the byatt floor (not shown in FIG.) longitudinally adjacent with wooden floor assembly 2 tilting section 21 are fixed by the outer flanging of countersunk head screw nail and end plate 7, thus are realized the connection between wooden floor assembly and longitudinal adjacent level wood covering.
Inclined support surface upper surface and the floor bearer upper surface of base are fixed with rubber pad all in advance, play good damping of vibrations.The tilting section end lower surface of wooden floor assembly is then fixed with wedge in advance, has the gap of filling between tilting section end and iron floor, improves place's wood covering intensity of entering.
Visible, the installation of interior structure of the present invention is simple, and production efficiency is high and quality good.
