In existing composite technology, developed multiple composite panel to replace traditional bamboo offset plate.Continuous fiber reinforced thermoplastic polypropylene honeycomb composite panel is exactly one of them.This sheet material is for bus and motorcoach floor at present, but in use found various problems, as: cannot use traditional mode to connect, Traditional Wood floor self threading pin can directly extrude depression by honeycomb composite plate epidermis, after laying superficial floor leather, epidermis has obvious pit phenomenon, when seat position is installed, in seat foot, there is large area depressed phenomenon especially, had a strong impact on overall appearance and the service life on floor.
The form that has part producer to adopt Puttying or beat hot melt adhesive is filled and led up floor, as shown in Fig. 7 to Fig. 8, but effect is extremely slowly on the impact of existing manufacturing line greatly, and in nailing process to the bad control of moment of torsion, in bus driving process, easily there is to jump nail phenomenon (as shown in Figure 9).Simultaneously traditional honeycomb composite floor board Facing material is PP polypropylene material, cannot use glue to be connected, or very easily occur obscission after bonding between this material and surperficial PVC flooring laminate.
Therefore, the bind strength that how to reduce bus deck weight, increase floor intensity, improves between floor decay resistance and honeycomb composite plate and PVC flooring laminate is the problem that current numerous bus factory all faces, and the solution of this series of problems is by passenger vehicle, lightweight brings important meaning.
Utility model content
The purpose of this utility model is: the problem existing for above-mentioned prior art, proposes the large firm lightweight bus deck that performance is good, decay resistance is high, bind strength good and good looking appearance is durable of a kind of intensity.
In order to reach above object, the technical solution of the utility model is as follows: a kind of lightweight bus deck, comprise composite panel, composite panel anchor fitting, the support beam being connected with vehicle frame, described composite panel comprises plate core and is arranged on the upper lower epidermis of described plate wicking surface, described composite panel anchor fitting comprises fastener and is arranged on the lining of described fastener periphery, it is characterized in that: also comprise the auxiliary layer of being located at described epicuticle upside, described plate core is provided with the passage that holds lining, described epicuticle is provided with the opening corresponding with passage, described lower epidermis touches mutually with lining, described fastener is connected through described lining and described support beam.
A kind of preferred structure of the present utility model is as follows:
Preferably, in the middle of described lining, have through hole, described lining vertical section is with the axisymmetric double C shape in lining center or two L shaped; Described fastener consists of head and bar portion; Described fastener head diameter > insert diameter > fasteners shank diameter.Can carry well like this pressure while installing, make fastener mounting torque more reliable more greatly, also can not cause damage to lower epidermis simultaneously.
Preferably, after the assembling of described floor, it is concordant with composite panel upper surface that vertical section is the fastener top of locating at the L shaped lining place of symmetric double; It is concordant with composite panel upper surface that vertical section is the lining top of symmetrical double C shape.Like this, on the one hand, fastener top keeps concordant, not easy to wear and good looking appearance with composite panel upper surface; On the other hand, can carry better the pressure while installing.
Preferably, it is PET nonwoven fabrics that described auxiliary layer adopts terylene hot rolling continuous yarn non-woven fabrics material, described auxiliary layer is fixed on described epicuticle through the pressing of thermoplastic composite technique, greatly improved thus the surface polarity of upper epidermis, by gluing can be bonding with PVC flooring laminate easily, there will not be the problems such as delamination.
Preferably, also comprise the PVC flooring laminate of being located at described auxiliary layer upside, described auxiliary layer is bonding by adhesion agent and described PVC flooring laminate.
Preferably, after the assembling of described floor, without seat place, fastener is connected through auxiliary layer, lining and support beam successively; At seat place, fastener is connected through seat pin, PVC flooring laminate, auxiliary layer, lining and support beam successively.So both can fixed floor and seat, do not affect the appearance again.
Preferably, described lining is the metal lining of wall thickness 1-3mm.
Preferably, described fastener is thread-forming screw.
Preferably, described plate core is thermoplastic plastic honeycomb core or aluminium honeycomb core, and the material of described upper lower epidermis is continuous fiber reinforced thermoplastic composite material.
Compared with prior art, the utlity model has that good stability, weight are light, the advantage such as good looking appearance, corrosion resistance and good, long service life, bind strength are good.
