And after the die is disassembled, a thin iron rod matched with the through hole is inserted into the through hole to rotationally disassemble the cone, and the cone is reused.
The device has the advantages that: this device is through the thickness standard of self height as concreting, compare in current mode, it is more directly perceived convenient, this device downside inserts in the template through the cone, the installation is stable, the bearing that two strip reinforcing bars on this device correspond respectively in two-layer reinforcing bar net below, and be determinant in the floor mould of waiting to pour and arrange, can prevent effectively that the reinforcing bar net from compressing deformation, built-in reinforcing bar net plays the effect of reinforcing its self intensity in this device, this device is buried wherein after concreting, the cone of its bottom adopts detachable threaded connection mode, can dismantle the multiplexing after the form removal.
In order to achieve better use effect of the device, the preferable scheme is as follows:
preferably, the cylindrical main body is circumferentially provided with a plurality of annular grooves which are arranged at intervals along the height direction.
The annular groove can allow the concrete poured later to enter the annular groove, so that the device is better combined with the concrete poured later, and the overall structure of the floor slab is more stable.
Preferably, the axial directions of the two strip-shaped reinforcing bars are perpendicular to each other.
The warp and weft in the two layers of reinforcing steel bar meshes can be respectively supported by the structures with the axis directions of the two strip-shaped reinforcing steel bars being mutually perpendicular, so that the stress is more uniform and stable.
