The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, bridge mounting and positioning device of the present utility model comprises posting 1 and the longitudinal register bar 2 that is attached thereto, posting 1 is provided with first locating surface 11, second locating surface 12 and the 3rd locating surface 13, wherein second locating surface 12 and the 3rd locating surface 13 are parallel to each other and perpendicular to first locating surface 11, the distance L 1 of second locating surface 12 and the 3rd locating surface 13 equals to design the transverse width B1 of bearing, be L1=B1, longitudinal register bar 2 is provided with parallel with second locating surface 12 and perpendicular to the 4th locating surface 21 of first locating surface 11, and the 4th locating surface 21 to second locating surfaces 12, the distance of the 3rd locating surface 13 equates, the 4th locating surface 21 is provided with the visual telltale mark line 3 vertical with the 4th locating surface 21, the distance L 2 of visual telltale mark line 3 and first locating surface 11 equals the poor of the design bearing vertical width B 2 of case beam support point to case beam-ends identity distance from L and 1/2, i.e. L2=L-B2/2.Use this bridge mounting and positioning device, with posting 1 bearing 8 that reclines, posting 1 is drawn out to the cross central line of bearing 8 position of first locating surface 11, longitudinal register bar 2 is drawn out to the longitudinal centre line of bearing 8 position of the 4th locating surface 21, cross hairs on the bearing 8 directly leads to visual telltale mark line 3 places on the mounting and positioning device the most at last, the discrepancy in elevation of the cross hairs of this mark and case beam-ends face bottom is reduced to about 15mm, needn't utilize the plumb bob contraposition, directly utilize installer's just accurately contraposition of perusal, minimizing has improved installation effectiveness and the accuracy of bridge to bit time.
