A column formwork perpendicularity detection device based on a horizontal pipe belongs to the technical field of building construction auxiliary tools and comprises a ruler body, the bottom end of the ruler body is rotatably connected with a lower distance plate in the circumferential direction through a fixing screw, the ruler body is connected with an upper adjusting plate through a pointer screw, one end of the upper adjusting plate is provided with a sliding groove, and the other end of the upper adjusting plate is provided with a horizontal pipe. The pointer screw penetrates through the sliding groove of the upper adjusting plate and is slidably connected with the top end of the ruler body. And support is provided for rapidly determining the perpendicularity deviation of the vertical face at any angle in building column formwork construction. Moreover, the detection device is simple and rapid to operate, and the adjustment of the horizontal pipe is more accurate and rapid compared with the traditional pl
