High 0.50～1.25m) and following condition in survive, application scenario was very limited with opportunity.
Naval counterpart multi-use buoyancy tank later, increases buoyancy tank height and buoyancy tank joint dimension, thus improve the bridge that swims
The bending resistance of section, the ability adapting to wave increases, and adapts to wave height close to 2.0m.Theoretically, if carried further
High box height and increasing joint dimension are it is also possible to improve the existence wave height of coast-floating stage, but too high buoyancy tank and the bridge that swims
Section leads to transverse stability to decline, and is unfavorable for spelling group job, using high-strength alloy steel and size is difficult to increase buoyancy tank joint again.For
Prevent impaired in wave, also need at this stage to decompose coast-floating stage and keep away wave.The high middle wave condition in 1.25～2.50m for wave
Under there is no matured product.
In order to be able to using in bigger wave environment and surviving, Chinese invention patent application " a kind of coast-floating stage from
Method for improving " (application number：2013104189200, publication date：2015.3.25) and Chinese invention patent application " a kind of light-duty,
Have from floating function and can the elevated structure that sets up of manpower " (application number：2014102604383, publication date：2014.9.10) carry
Gone out a kind of first set up the bridge that swims, after be promoted to the technical thought of overhead trestle.But after coast-floating stage is promoted to overhead trestle, bag
Include trestle deadweight and bridge floor load is undertaken by supporting leg in interior whole load, high to the force request of supporting leg, cause overhead trestle
Logical loading capability relatively limited, do not reach coast-floating stage and rely on the logical loading capability that formed of buoyancy.
In a word, prior art there is problems that：Coast-floating stage opposing vertical bending moment and antitorque ability weak it is difficult in
Under the conditions of wave, existence uses.
Content of the invention
It is an object of the invention to provide a kind of case purlin combination type coast-floating stage, opposing vertical bending moment and antitorque ability
By force, effectively existence can use under the conditions of middle wave.
The technical solution realizing the object of the invention is：
A kind of case purlin combination type coast-floating stage, including multiple continuous splicings the bridge section and being used for of swimming constrain described in swim bridge
The anchor of section displacement and anchor chain, the truss that the described bridge section that swims includes buoyancy tank and is symmetrically fixedly arranged on described buoyancy tank top both sides, also wrap
Include strut, described strut two ends are fixedly connected with the truss of described buoyancy tank top both sides respectively.
Compared with prior art, its remarkable advantage is the present invention：
1st, resisting longitudinal moment of flexure ability is strong：Buoyancy tank adds truss, the adjacent bridge section that swims is by buoyancy tank joint and Truss joint
Connect, improve the vertical distance of coast-floating stage jointing, thus in the case of joint bearing capacity is not significantly increased, significantly
Improve the ability that coast-floating stage resists vertical bending moment.
2nd, torsional rigidity is good：Cross struts are set between truss on buoyancy tank, while improving truss stability, also improve
The torsional rigidity of coast-floating stage bridge section, thus improve the torsional property of coast-floating stage bridge section and whole bridge.
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
