The invention discloses the technical field of building engineering and particularly relates to a scribing isolation vehicle for house building construction. According to the dangerous area scribing reminding device for building engineering construction, when lime powder is scattered, the working efficiency is high, scattering is uniform, an isolation line is attractive, and the construction costcan be reduced. The scribing isolation vehicle for house building construction comprises a vehicle plate, wheels, a support, a material cylinder, first bearing seats, a stirring shaft, a large belt wheel, a feeding hopper, a discharging pipe, a discharging valve, a first motor and the like. The wheels are arranged at the bottom of the vehicle plate, the support is installed on the top of the vehicle plate in a bolted connection mode, and the material cylinder is installed on the inner side of the support. The effects that when the lime powder is scattered, the working efficiency is high, scattering is uniform, the isolation line is attractive, and the construction cost can be reduced are achieved.
