Abstract: The present invention relates to a method for piping heat without expansion pipe joint, allowing an interval of a through hole to be constructed larger than the expansion amount of the pipe in a pipe branched into each layer by passing through a through hole disposed in a fireproof divided wall body in a vertical pipe for supplying various types of fluids into a pipe pit in a building, and charging the interval of the through hole via a fireproof and expanded heat-resistant through hole support hole. Accordingly, the vertical pipe can be expanded in the axial direction in accordance with a change in temperature so as to enable a branch pipe to be supported by allowing the same to elastically respond to a position change of the branch pipe caused due to the expanded heat-resistant through hole support hole when the vertical position of the branch pipe in the through hole is changed. Moreover, the branch pipe can be piped without expansion joint so as to prevent an anchor force from being caused in a support unit of the pipe, thereby piping with a simple and stable pipe.
