The present invention relates to a scaffold system, where four vertical members are vertically stood and installed at an interval, first to fourth horizontal members are connected and installed in connection members provided to each vertical member, and a scaffold support is installed in the first to fourth horizontal members to enable locking units provided to the first to fourth horizontal members to be rapidly and easily coupled to and separated from the connection members installed to be coupled to and separated from the multiple vertical members to enable the vertical members and the first to fourth horizontal members to be rapidly and easily coupled in a construction site to be stably stood and installed to rapidly and easily separate the members after use, to enable the connection members to be easily separated from and coupled to the vertical members, and to enable the first to fourth horizontal members to be separated from and coupled to the connection members of the vertical members to more easily store the horizontal members.COPYRIGHT KIPO 2021
