Transport, storage aspect, existing basis are transported by the way of stacking, and the layer on basis is prevented by outside binding mode
Relative displacement occurs between layer.But the weight weight in transit because based on also can between layers so inertia is big
It produces relative sliding, or even wirerope is snapped, basis is caused to scatter in transit.
Summary of the invention
The purpose of the present invention is to provide a kind of assembled steel reinforced concrete foundations of construction hoisting machinery, to solve existing base
The problem of easily scattering when plinth is by larger tilting moment, cause safety accident.
In order to achieve the above object, base case of the invention provides a kind of construction hoisting machinery assembled steel reinforced concrete
Basis, is strained and fixed the pressing plate layer of part and several stackings including several longitudinal directions, and pressing plate layer is pressed made of several armored concrete
Plate unit is spliced, and the pressing plate unit on stacking direction in two adjacent pressing plates layers intersects, the pressing plate unit of each pressing plate layer
