The invention discloses a noise reduction type building construction device constructed by utilizing a mechanics principle. The noise reduction type building construction device comprises a bottom plate, the top of the bottom plate is connected with a top plate through rubber springs, the periphery of the top of the top plate is connected with vertical plates through clamping mechanisms, cavitiesare formed in the vertical plates, and sound insulation cotton is bonded to the inner walls of the cavities; a plurality of conical covers are fixedly connected to the inner sides of the vertical plates, one ends of the conical covers are located in the cavities and fixedly connected with cylinders, a plurality of first through holes are formed in the outer surfaces of the cylinders, first conicalblocks are fixedly connected to the outer sides of the cylinders, and the first conical blocks are located at the two sides of the first through holes; and second conical blocks are bonded to the tops and the bottoms of the cavities, a plurality of second through holes are formed in the sides, away from the conical covers, of the vertical plates, and fixing mechanisms are fixedly connected to thesides, close to the second through holes, of the vertical plates. The noise reduction type building construction device has the beneficial effects that noise reduction operation can be conducted on noise generated by work of construction equipment, and meanwhile the equipment can be fixed.
