The invention relates to an engineering building auxiliary tool, and in particular relates to an engineering building construction scaffold, consisting of standpipes and transverse pipes, wherein the standpipes consist of four steel pipes, a standpipe locating plate and a standpipe connecting plate; the standpipe locating plate is a cross stamped part; through holes are arranged on the middle part of the standpipe locating plate; the four steel pipes are fixed on four corners of the standpipe locating plate; the standpipe connecting plate is fixedly connected at two ends of the standpipe; twostandpipes are connected via a standpipe connector; the transverse pipes are inserted from two rows of steels pipes of the standpipes and are located on the standpipe locating plate; the transverse pipes are locked on the standpipes via a pipe clamp; and two transverse pipes are connected via a transverse pipe connector. The standpipes adopting the structure of four pipes greatly increases the loading capacity of the scaffold, improves the stability of the scaffold, saves more than 60% of mounting time, improves the working efficiency and greatly shortens the construction period.
