Detailed Description
As shown in fig. 1 and 2: a control method for transverse load distribution when a multi-column module vehicle translates an overlong member, wherein the overlong member is a steel structural member with the length of more than 60 meters. It comprises the following steps:
the method comprises the following steps: through drawing analysis and checking calculation, the bearing capacity of each part of the floor slab and the actual mass distribution of each section of the member are determined, so that the load required to be borne by each group of module cars 1 is determined; the adjustment of the pressure distribution values must be carried out according to a predetermined scheme to ensure that the module car equipment and the floor slab are not overloaded, and the predetermined pressure distribution values must be calculated in advance by strict expertise to ensure the construction safety.
Step two: jacking in an empty load stage when the module car group is in a lifting independent control state, and ensuring that a top bracket of each module car just contacts with the lower surface of the lower chord of the truss unit and slightly jacks; in the pressure distribution value adjusting process, each group of module vehicles need to be in an independent control state.
Step three: wired bridging and parallel connection are carried out among all groups of module vehicles, so that all rows of module vehicles can synchronously act (walk, lift and the like); and a table showing the corresponding relation between the pressure and the pressure value is drawn in advance, so that the load value shared by a certain group of module vehicles can be conveniently and quickly determined by looking up the table.
Step four: loading and top testing are carried out step by step according to the proportion of 20%, 40%, 60%, 80% and 100% of the total load; the load is judged according to the pressure value shown by the corresponding pressure gauge on each group of module vehicle control panels, and the specific numerical value can be checked through the pressure-load corresponding relation table.
Step five: in view of the sensitivity problem of the gauge, under the condition of low load, a pressure gauge with small range (high sensitivity) connected in parallel is adopted to display the pressure value;
step six: after each roof test is finished, whether the pressure value displayed by the pressure gauge of each module car group meets the requirement needs to be observed, and the single module car roof lift force can be finely adjusted if necessary; if the fine adjustment of the lift force of the roof of the individual group module needs to be carried out, the fine adjustment needs to be carried out in an independent control mode, and the load conditions of other group module vehicles are observed at the same time.
As can be seen from the figure 1, the mass distribution of the truss along the length direction is not uniform, the distribution positions of the module cars are also not uniform, and the bearing capacities of the waffle boards in different areas are not uniform due to the influences of the factors of uniform height and size of the cross section of the truss, non-uniform positions of the support towers, non-uniform positions of concrete columns, non-uniform thicknesses of the waffle boards in different areas and the like. This requires that the load distribution values of the module cars at different positions are reasonably designed in advance to determine the maximum allowable load of the module car at each position. And in the construction process, the actual load of each group of module vehicles is controlled within an allowable reasonable range.
As shown in fig. 2, the five rows of module cars are divided into three groups, and the number of the axes is 12, 8 +8 and 8 +8 from right.
