The utility model relates to a civil engineering equipment technical field especially relates to stair template reinforcement member that marks time. This stair template reinforcement member that marks time includes the stair template of marking time, establishes steel pipe pole setting and lower steel pipe pole setting respectively at the upper and lower side's platform of stair, and the steel pipe down tube is established to the stair top between last, lower steel pipe pole setting, and steel pipe down tube both ends are connected with last, lower steel pipe pole setting, establish a plurality of L shaped steel pipe on the steel pipe down tube, L shaped steel pipe upper portion links to each other with the steel pipe down tube, and L shaped steel pipe lower part and stair are marked time, and the template is parallel to correspond the setting, stair mark time the template rather than correspond and establish the flitch between the L shaped steel pipe lower part that sets up, to mark time the template continuous with L shaped steel pipe lower part joint with stair respectively at the flitch both ends. This stair template reinforcement member that marks time reinforces that effectual, work progress mezzanine ladder rung difficultly takes place that deformation and offset, improvement mark time that the shaping quality of concrete, all transsexuals are higher, repeatedly usable, the further construction potential safety hazard of eliminating.
