Combination structure of upper horizontal pillar and upper vertical pillar for bus

摘要

The present invention relates to a couplstructure of an upper horizontal pillars and an upper vertical pillars for buses, and includes a plurality of upper horizontal pillars 30 on which left and right side fastenportions 32 and 35 are formed at left and right ends, respectively; A first vertical pillar 52 in which a lower side insertportion 55 is formed at an upper end in a vertical lower portion of the left and right side insertportions 32 and 35, And a second vertical pillar (57) havan upper pillar (59) at a lower end thereof; Right side couplholes 90b and 90a are formed at the right end of the upper horizontal pillar 30 so that the left and right side insertion portions 32 and 35 of the upper and lower horizontal pillars 30 are inserted into the upper and lower insertion portions 59 and 59 And a plurality of connection brackets (90) hava " + " shape in which upper and lower engagement holes (90c) and (90d) are formed at upper and lower ends so as to be fitted and joined, respectively, The upper horizontal pillars and the upper vertical pillars can be prevented from crackand the fatigue accumulated in the upper horizontal pillars and the upper vertical pillars can be restricted to relieve the fatigue stress of the vehicle body, So that the joinprocess between the upper horizontal pillar and the upper vertical pillar can be simplified and the work efficiency can be improved.
