Abstract
The utility model relates to an aluminum honeycomb floor board which is characterized in that a front skeleton, a rear skeleton and left and right side beams are connected to form a cavity-shaped frame, aluminum honeycomb is filled in the cavity-shaped frame, and a face board and a rear board are respectively arranged above and below the cavity-shaped frame. In the utility model, the front skeleton, the rear skeleton and the left and right side beams are connected to form the cavity-shaped frame, the aluminum honeycomb is filled in the cavity-shaped frame, and the face board and the rear board are respectively arranged above and below the cavity-shaped frame. Reinforcing beams inside the aluminum honeycomb floor board are omitted, the problem of heavy floor board structure is solved, the requirement of novel urban rail vehicles for light weight is satisfied, and the production cost of the floor board is lowered under the premise of not curtailing the performance parameters of the floor board per se.
Description
Technical field
The utility model relates to the improvement of novel track vehicle body floor structure, especially relates to a kind of weight-saving aluminium honeycomb floor.
Background technology
In recent years, home and abroad subway vehicle user is more and more stricter to the requirement of vehicle weight, so the light-weight design of vehicle is crucial day by day.The floor has very important position in vehicle structure, occupy very big ratio on the distribution of weight naturally.The side bar section material section of aluminium honeycomb floor was comparatively thick and heavy in the past, and the aluminium honeycomb sandwich construction is that upper and lower surface is the aluminium sheet of 2mm, and the centre is the structure of aluminium honeycomb; Entirely there is support beam structure anyhow in the plate.This kind structure intuitively goes up the effect of the floor being played support reinforcing, has in fact but destroyed the intensity that aluminium honeycomb core supports as a whole, and has increased the weight on floor itself, and productive costs also improves thereupon.
The utility model content
The purpose of the utility model provides a kind of lightweight floor panel structure, under the prerequisite of not cutting down the performance perameter in floor own, has reduced the productive costs on floor.
For realizing above-mentioned purpose, the utility model provides a kind of aluminium honeycomb floor, it is characterized in that: connect and compose chamber shape framework by preceding skeleton, back skeleton and left and right sides side bar, be filled with the aluminium honeycomb in the shape framework of chamber, have panel and backboard on the shape framework of chamber.
The utility model connects and composes chamber shape framework by preceding skeleton, back skeleton and left and right sides side bar, is filled with the aluminium honeycomb in the shape framework of chamber, has panel and backboard on the shape framework of chamber.Cancellation aluminium honeycomb floor in-to-in strength beam has solved the heavy structure on floor itself, has satisfied novel city rail vehicle to the weight-saving requirement, under the prerequisite of not cutting down the performance perameter in floor own, has reduced the productive costs on floor.

The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model connects and composes chamber shape framework by preceding skeleton 1, back skeleton 2, left and right sides side bar 3, is filled with aluminium honeycomb 4 in the shape framework of chamber, and chamber shape framework is stained with panel 5 and backboard 6 with assembly glue 7 up and down.
Claims (1)
1. an aluminium honeycomb floor is characterized in that: connect and compose chamber shape framework by preceding skeleton, back skeleton and left and right sides side bar, be filled with the aluminium honeycomb in the shape framework of chamber, have panel and backboard on the shape framework of chamber.
