Abstract
The invention relates to a main bridge frame structure of an overpass, in particular to an overpass support frame splint connecting device, which comprises an upper cross beam, a lower cross beam, a vertical beam and oblique beams, wherein two ends of the upper cross beam and the lower cross beam are fixedly arranged on a support frame, the upper cross beam is connected with the lower cross beam in an H shape through the vertical beam, one end of each oblique beam is fixedly arranged on a joint of the upper cross beam and each upright tube of a vertical face, and the other end of each oblique beam is fixed to a joint of the vertical beam and the lower cross beam. The device disclosed by the invention has a reasonable structure, and high stability, reliability and durability, and the overall effect is neat and practical.
Description
Technical field
The present invention relates to a kind of overline bridge master portal structure, a kind of overline bridge bracing frame of special design clamping plate linkage.
Background technology
At present, " mouth " font aluminium alloys overline bridge is to adopt bracing frame and transition truss overlap joint truss form, and its main feature increases the bearing capacity of bridge, strengthens the stability of aluminium alloys overline bridge, guarantees not occur rocking after the installation of " mouth " font aluminium alloys overline bridge.
But in prior art, the structure stress shakiness, easily occur rocking, and adopt welding manner manufacture " mouth " font aluminium alloys overline bridge more mostly, and cost is higher, and the cycle is longer.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of overline bridge bracing frame clamping plate linkage that overcomes above-mentioned prior art defect.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of overline bridge bracing frame clamping plate linkage, comprise top rail, lower transverse beam, vertical beam and cant beam, the two ends of described top rail and lower transverse beam are fixed in the facade vertical rod, described top rail is " work " font and is connected with lower transverse beam by vertical beam, junction, the other end that described cant beam one end is fixed on top rail and facade vertical rod is fixed on the junction of vertical beam and lower transverse beam.
The invention has the beneficial effects as follows: rational in infrastructure, stability, reliability and durability are high, and whole structure is neat and practical.
On the basis of technique scheme, the present invention can also do following improvement.
Further, be connected and connect by bolt between described vertical beam and top rail.
Further, between described top rail, cant beam and facade vertical rod and lower transverse beam, vertical beam and cant beam by
Clamping plate connect.
Further, described overline bridge bracing frame clamping plate linkage is aluminum alloy material.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In accompanying drawing, the list of parts of each label representative is as follows:
1, clamping plate, 2, top rail, 3, clamping plate, 4, vertical beam, 5, lower transverse beam, 6, clamping plate, 7, cant beam, 8, the facade vertical rod.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, described overline bridge bracing frame clamping plate linkage comprises top rail 2, lower transverse beam 5, vertical beam 4 and cant beam 7, the two ends of described top rail 2 and lower transverse beam 5 are fixed in facade vertical rod 8, described top rail 2 is " work " font by vertical beam 4 and lower transverse beam 5 and is connected, and junction, the other end that described cant beam 7 one ends are fixed on top rail 2 and facade vertical rod 8 is fixed on the junction of vertical beam 4 and lower transverse beam 5.
Be connected and connect by bolt between described vertical beam 4 and top rail 2, be connected by clamping plate 1, clamping plate 3 and clamping plate 6 between described top rail 2, cant beam 4 and facade vertical rod 8 and lower transverse beam 5, vertical beam 4 and cant beam 7.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
