SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an aluminium slag ball vibrations screening installation.

In order to achieve the above purpose, the utility model adopts the following scheme:

the anti-floating screw for the hollow floor comprises a long rod capable of being longitudinally inserted into concrete, threads rotatably inserted into a mold plate are arranged below the long rod, a fixing piece is movably sleeved on the threads, a nut is fixed at the upper end of the long rod, and a baffle capable of fixing the concrete on the mold core through the fixing piece is sleeved on the long rod below the nut.

Furthermore, a round angle is arranged above the screw cap.

Furthermore, a plurality of semicircular salient points are fixed at the end part below the baffle at intervals, and the baffle is circular.

Preferably, the thread has a taper with an external angle of 60 to 65 degrees.

Preferably, the thread pitch is 2 mm to 2.2 mm.

Preferably, the nut and the fixing member are hexagonal in shape.

Preferably, the part for the fixing member is a nut or a hoop.

To sum up, the utility model discloses for its beneficial effect of prior art is:

the above technical scheme is adopted in the utility model, can realize when building engineering goes on, the workman pours the concrete into the mould in shape, can produce buoyancy and come-up and remove because of the concrete placement in-process this moment, through running through the stock and peg graft on the mould, later rotate the nut through the spanner and make and rotate the stock, insert the mould template through the screw thread rotation when the stock rotates, fix, compress tightly baffle and mould through wrench movement mounting at last, contrast prior art, can add the construction speed of hollow superstructure in the building engineering, accelerate the installation rate of superstructure mould mandrel simultaneously, and is convenient and fast more, save the cost.
