The specific embodiment
Below in conjunction with the drawings and specific embodiments to crossroad access bridge structure of the present invention and adopt the crossroad of this access bridge structure to be described further, to help understanding the object of the invention.
As shown in Figures 1 and 2, the crossroad access bridge structure is by two of horizontal direction parallel vertical bridges, i.e. first vertical bridge 1 and second vertical bridge 2, and four skew auxiliary bridges 3,4,5,6 constitute.
Two vertical bridges 1,2 adopt semi-moon shaped arch bridge structure, and the length of its bridge, height are all identical.
First skew auxiliary bridge 3 and second skew auxiliary bridge 4 and first vertical bridge 1 join, and pass for 2 times from second vertical bridge.The 3rd skew auxiliary bridge 5 and the 4th skew auxiliary bridge 6 and second vertical bridge 2 join, and pass for 1 time from first vertical bridge.
Preferable mode is that four skew auxiliary bridges 3,4,5,6 adopt circular bend so that skew auxiliary bridge is connected in tangent substantially mode with vertical bridge with the part that vertical bridge is connected as shown in the figure, make the vehicle on the tiltedly auxilliary car can steadily reach vertical bridge naturally, or on vertical bridge, drive towards skew auxiliary bridge.First vertical bridge 1 and skew auxiliary bridge 3,4, and second vertical bridge 2 can be nearer with the contact mutually of two skew auxiliary bridges 5,6, for example as shown in Figure 2, skew auxiliary bridge 3,4 tops link to each other and communicate with vertical bridge at first vertical bridge, 1 top, skew auxiliary bridge 5,6 tops link to each other and communicate with second vertical bridge, 2 tops, this mode is fit to small-scale crossroad access bridge structure, and compact conformation, floor space are little; Also can the wide bridge construction of multilane for example be arranged apart from far away.
