STAIR CONSTRUCTION METHOD FOR HIGH-RISE BUILDING USING SOUND BRIDGE BLOCKING DEVICE

摘要

The present invention relates to a stair construction method for a high-rise building using a sound bridge blocking device, capable of reducing noise by embedding and construction a hanger anchoring bar of a structure in which stairs are hung thereon between stairs and a wall and preventing the noise from being transmitted to each floor, an upper floor, or a lower floor around a landing space by installing a sound bridge blocking device at a part in which the landing space is connected to the stairs. According to a proper embodiment of the present invention, the stair construction method for a high-rise building comprises: (a) a step of embedding a hanger anchoring member to be embedded at every fixed height of the wall corresponding to a side of the stairs in order for the other side of a soundproof panel to be exposed; (b) a step of assembling a landing space mold at the fixed height of the wall in which the each landing space is constructed and arranging reinforcing bars; (c) a step of installing the sound bridge blocking device in order for a vertical unit of a support angle in a joint unit of the stairs and the landing space to protrude to the outer side of the landing space mold, wherein the sound bridge blocking device comprises a soundproof panel, a tension support bar, and a finishing plate inserted into each through hole of the soundproof panel; (d) a step of forming the stairs by placing concrete in the landing space mold (51); (e) a step of installing a stair mold to form stairs between the landing spaces, arranging the reinforcing bars, and attaching a soundproof material to the surface of the wall coming into the stair mold; and (f) a step of forming the stairs by placing and curing the concrete in the stair mold and removing the stair mold.;COPYRIGHT KIPO 2017
