Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Fig. 1 shows the structure of the pedestrian bridge from anchor force balance string Cable Structure that the embodiment of the present invention provides.For convenience of explanation, illustrate only the part relevant to the embodiment of the present invention.
Should comprise from the pedestrian bridge of anchor force balance string Cable Structure: bridge deck 6, eccentric structure 2, level open string rope 3, counterweight load 1, longitudinal strut 5, bridge deck 6 are arranged on level and open on string rope 3, level is opened string rope 3 and is connected with the eccentric structure 2 of both sides, eccentric structure 2 is provided with counterweight load 1, eccentric structure 2 and level are opened between string rope 3 and are provided with longitudinal strut 5, and level is opened between string rope 3 and longitudinal strut 5 and is provided with rod member.
In embodiments of the present invention, the bottom of eccentric structure 2 is provided with the strong point 4.
In embodiments of the present invention, counterweight load 1 can adopt massif, mountain stone, the soil body or the concrete block of gathering materials on the spot.
In embodiments of the present invention, eccentric structure 2 adopts wood material, braided steel wire net adding rock to make, and steel work, reinforced concrete structure also can be adopted to pour into a mould.
In embodiments of the present invention, bridge deck 6 can adopt steel plate or other class lightweight plates.
In embodiments of the present invention, level is opened string rope 3 and is longitudinally being had two strands at least.
Below in conjunction with drawings and the specific embodiments, application principle of the present invention is further described.
As shown in Figure 1 to Figure 3, the pedestrian bridge from anchor force balance string Cable Structure that the embodiment of the present invention provides, adopt heavier eccentric structure 2 by both sides, many levels open string rope 3, counterweight load 1 and longitudinal strut 5 and form, eccentric stent structure realizes more large eccentricity by the counterweight of setting up and rotates and open string rope 3 to level and realize stretch-draw, when span is larger, horizontal force balance can be realized by longitudinal strut 5 and support lower constraint, can open by level the stress deformation that the rod member arranged between string rope 3 and longitudinal strut 5 changes rope simultaneously.
