Specific embodiment
Next a specific embodiment of the invention is set forth in conjunction with attached drawing.
A kind of bridge hanging basket parameter calculates and emulation mode, includes the following steps:
Step 1, the three-dimensional entity model of Hanging Basket is established in d solid modeling software Midas；
Step 2, determine Hanging Basket important technological parameters and design basic parameter, such as each component needed for intensity, rigidity,
Monolithic stability and local stability；
Step 3, load and boundary condition are determined in Midas according to cradle structure computation model and relevant parameter, later
Load calculating is carried out to all load-carrying members of Hanging Basket.
In the present invention, the three-dimensional entity model for the Hanging Basket that the step 1 is established include load-bearing carrier bar 1, preceding branch seat support 2,
Diamond shape frame 3, suspension system 4 and anchor system 5, load-bearing carrier bar 1 are arranged on bridge floor, and load-bearing carrier bar 1 is passed through by many carrier bars 11
It is bolted, preceding branch seat support 2 is arranged on carrier bar 1, and diamond shape frame 3 is arranged on preceding branch seat support 2, and suspension system 4 is logical
It crosses the connection of upper beam 41 to be arranged on diamond shape frame 3, suspension system 4 is transferred in suspension system by sunpender 42 for pouring mixed mud
Formwork structure, the present apparatus also completes for Hanging Basket to be fixed on bridge by anchor system, as shown in Fig. 2.
According to the occurrence frequency of mechanical analysis and the accident of previous practice of construction process it is found that the accident frequency of Hanging Basket equipment
