Abstract
The floor of railway vehicle press strip that the present invention relates to is rectangular section bar, comprises press strip main body, and press strip main body section is formed by connecting through arc-shaped transition parts by Cross slat and oblique bar, and Cross slat is connected through fastener and outside underframe; Transition member extends towards the side away from Cross slat the supporting leg contacted with outside underframe; The end face of Cross slat has one group of groove spaced apart, and the bottom surface of Cross slat has depression, and Cross slat has away from the end of oblique bar the lap joint contacted with outside underframe; Oblique bar extends away from Cross slat direction the elbow contacted with outer side wallboard away from the end court of Cross slat; Oblique bar is fixed with the elastic strip offseted with outer side wallboard near the side of outer side wallboard.The degree of modularity of the present invention is high, can realize dismounting separately on the basis meeting Layering of floors requirement.
Description
Technical field
The present invention relates to a kind of floor of railway vehicle press strip, be particularly useful for railcar.
Background technology
According to the knowledge of the applicant, Layering of floors in in-built for guideway vehicle, requirement can realize the transition between in-built underframe and framed side wallboard, play beauty function, the vacancy between underframe and framed side wallboard can be made up simultaneously, prevent the water in guest room from entering underframe and framed side wallboard inside, want wear-resisting anti-delineation in addition.
Although existing Layering of floors can meet the demands in structure function, modular design is thorough not, and the later stage is easy care not.If when needing to change chassis component as floor cloth, aluminium cellular components, not only will Layering of floors be removed, also to remove the framed side wallboard that is connected the with it even side wall module parts such as seat, add the production of product and maintenance intervals and maintenance cost.
Through retrieval, do not find specially for the Layering of floors patent of guideway vehicle, only there is the Patents for other field such as household, automobile, such as a kind of Layering of floors with soft limit disclosed in application number 201120328508.6 Chinese utility model patent, and these patents cannot to be applicable to guideway vehicle in-built, be difficult to use for reference.
Summary of the invention
Technical matters to be solved by this invention is: overcome prior art Problems existing, and provide a kind of floor of railway vehicle press strip, the degree of modularity is high, can realize dismounting separately on the basis meeting Layering of floors requirement.
The technical scheme that the present invention solves its technical matters is as follows:
Floor of railway vehicle press strip, be rectangular section bar, comprise press strip main body, it is characterized in that, described press strip main body section is formed by connecting through arc-shaped transition parts by Cross slat and oblique bar, described Cross slat is connected through fastener and outside underframe; Described transition member extends towards the side away from Cross slat the supporting leg contacted with outside underframe; The end face of described Cross slat has one group of groove spaced apart, and the bottom surface of described Cross slat has depression, and described Cross slat has away from the end of oblique bar the lap joint contacted with outside underframe; Described oblique bar extends away from Cross slat direction the elbow contacted with outer side wallboard away from the end court of Cross slat; Described oblique bar is fixed with the elastic strip offseted with outer side wallboard near the side of outer side wallboard.
In this structure, supporting leg can play reinforcement and position-limiting action, avoids oblique bar when mounted to break because excessively bending; Cross slat end face groove and bottom surface depression fully can discharge the stress that in installation process, Cross slat produces, and avoid Cross slat to break; Cross slat lap joint and oblique bar elbow can with outside underframe or framed side wallboard be seamless connects, and plays sealing function; Elastic strip can ensure the sealing of whole press strip and framed side wallboard further, and meets the demand to controllability when press strip is installed by self-deformation.After adopting this structure, whole press strip is a module, itself and framed side wallboard is closely offseted and is fixed on underframe, namely realizing the transition between underframe and framed side wallboard with appearance attractive in appearance, and the vacancy made up between underframe and framed side wallboard, anti-sealing in guest room, enter underframe and framed side wallboard is inner.Meanwhile, press strip can be dismantled separately when needed, framed side wallboard and side wall module parts can not be brought disaster to.
The perfect further technical scheme of the present invention is as follows:
Preferably, the cross section of described elastic strip comprises the vertical edges be connected towards the side of framed side wallboard with oblique bar, and described vertical edges is connected towards the side of framed side wallboard and the two ends of semicircular ring, is arranged with upper and lower buffering muscle outside described semicircular ring.Elastic strip can be made like this to play a role better.
Preferably, described oblique bar has the radian bending towards framed side wallboard.
Preferably, region residing for the some grooves of region overlay end face residing for the depression of described Cross slat bottom surface.
Preferably, described Cross slat, oblique bar, transition member are one-body molded.
The degree of modularity of the present invention is high, can realize dismounting separately on the basis meeting Layering of floors requirement.

Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the enforcement schematic diagram of Fig. 1 embodiment.
Fig. 3 is the a-quadrant enlarged drawing of Fig. 1.
Detailed description of the invention
With reference to the accompanying drawings and the present invention is described in further detail in conjunction with the embodiments.But the invention is not restricted to given example.
Embodiment
As shown in Figure 1 to Figure 3, the floor of railway vehicle press strip of the present embodiment is rectangular section bar, comprises press strip main body, and press strip main body section is formed by connecting through arc-shaped transition parts 3 by Cross slat 1 and oblique bar 2, and Cross slat 1 is connected through fastener 4 and outside underframe 5; Transition member 3 extends the supporting leg 6 contacted with outside underframe 5 towards the side away from Cross slat 1; The end face of Cross slat 1 has one group of groove 7 spaced apart, and the bottom surface of Cross slat 1 has depression 8, and Cross slat 1 has away from the end of oblique bar 2 lap joint 9 contacted with outside underframe 5; Oblique bar 2 extends away from Cross slat 1 direction the elbow 10 contacted with outer side wallboard 11 away from the end court of Cross slat 1; Oblique bar 2 is fixed with the elastic strip 12 offseted with outer side wallboard 11 near the side of outer side wallboard 11.
The cross section of elastic strip 12 comprises the vertical edges 12-1 be connected towards the side of framed side wallboard 11 with oblique bar 2, and vertical edges 12-1 is connected towards the side of framed side wallboard 11 and the two ends of semicircular ring 12-2, is arranged with upper and lower buffering muscle 12-3,12-4 outside semicircular ring 12-2.
In addition, oblique bar 2 has the radian bending towards framed side wallboard 11.Region residing for the some grooves 7 of region overlay end face residing for the depression 8 of Cross slat 1 bottom surface.Cross slat 1, oblique bar 2, transition member 3 are one-body molded.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of application claims.
