I am getting ready to buy a small aluminum building from Lowes Hardware and this one comes without a floorHow can I secure it to the ground to keep it from blowing away or at least weight the bottom of it down with a floor or studs anchored? It will be used for storing the lawnmower,gardening tools and a freezer.
I like placing pressure treated 4x6 on the ground where the building contacts the groundDig a post hole at each corner of the building below the frost line Bend a piece of rebar, in the shape of a u,over the 4x6 and fill hole with sackcrete covering both ends of the rebar by 6 inchesI then screw the building to the 2x6Use a 1x4 as a spacer between the building and the 2x6So the rebar has room over the 2x6If you want a floor I would use wood nailed to the 4x6depending on the size of the building you might need additional 4x6 in the center I would space at 24 inches.
If an object is uniform, it's a fair bet the centre of mass will be at the centre of the shapeIf lifting with slings, he will have them placed equidistant from centre, at an angle to each other not exceeding 60 degreesHe will then lift a little, and can tell by the angles from vertical of each sling whether or not the CM is under the centre of the crane cableIf not, he will lower the load, and have someone adjust the sling positionsHaving slings equally loaded ensures a level load when lifting, and when a load is level it is a much safer lift than when it tilts one way or the otherA tilt would mean greater force in the sling on the low endThe load could slip out, or the excess force could break the sling.
