In one embodiment of the invention, on lifting machine, floor diffusion wheel load reinforced construction method comprises:
Namely step 1: calculate floor when lifting machine (as automobile) is walked and whether can ftracture because load is excessive, also determine whether to need diffusion wheel load to reinforce; If needed, then carry out step 2; Otherwise directly carry out step 4;
Step 2: according to the thickness of the earthing on dissimilar lifting machine determination floor and the diffusion wheel load reinforced plate on earthing;
Step 3: the thickness determined according to step 2 lays earthing and reinforced plate on floor;
Step 4: floor on lifting machine.
Wherein, step 1 can adopt existing method of calculating, in order to determine whether that needs carry out diffusion and reinforce.
In step 2, earthing on structure floor and the thickness of reinforced plate have diffusion to lifting machine wheel load, earthing and reinforced plate thicker (within the specific limits), automotive wheels companding falls apart more abundant (wheel pressure angle of diffusion, can by 45 ° of considerations in cement concrete or reinforced plate, can by 30 ° of considerations in earthing), when overburden layer thickness and reinforced plate thickness reach enough thick, automobile wheel load can be considered by uniform load.The wheel load of automobile can be calculated by the average load of automobile within the scope of reasonable area of conter.(wherein enough thickness of earth covering numerical value should be determined according to engineering experience, when without Reliable Design experience, can be not less than determine that corresponding thickness of earth covering is h by the automobile area of conter of loading ratio cut partition by the diffusion area of rear axle wheel load
