Definitions

  • the present invention relates to a dry concrete silo device.
  • This invention relates to the field of building, particularly that of the manufacture of devices designed to ensure the storage and distribution of dry concrete.

  • such a frame comprises an annular support, through which is engaged the lower part of said reservoir, and a plurality of feet, extending from the annular support, and resting on the ground.
  • the lower part of the tank comprises a conical hopper below which is implanted the means for discharging the tank.
  • such a silo device is designed to be, first of all, filled with dry concrete and then to be routed and installed on a construction site. This allows, when the reservoir of such a device is empty, to substitute such a device by another identical or similar.
  • a specially designed transport truck provided with means for loading and unloading such a silo device. Since the loading / unloading capacities of such means are limited by the weight of the object to be loaded / unloaded, it is necessary to limit the weight of the silo device and, consequently, the amount of concrete contained therein the tank of this silo device. Such a limitation implies a greater rotation of the transport trucks which can travel considerable distances between the building site and the filling plant of these silo devices.
  • the dimensions (length, width, height) of the load likely to be transported by these transport trucks is limited, which consequently also limits the dimensions of the silo devices which are transported in a recumbent manner by these trucks.
  • the lower end of the tank of this device is situated at a low height relative to the ground level on the silo device. which device is implanted. This low height complicates the operations of unloading the tank and conveying the dry concrete to the place of its use.
  • the present invention aims to overcome the disadvantages of silo devices of the state of the art.
  • the invention relates to a dry concrete silo device comprising a reservoir for containing dry concrete, a means for discharging the reservoir, and a structure, intended to rest on the ground, and receiving, internally, the reservoir and at least a portion of the means for discharging this reservoir.
