Joint plugging device for modular wall construction

The utility model relates to a joint plugging device for modular wall construction, which comprises single-side mechanisms arranged oppositely, an opposite-pull screw rod is arranged between the single-side mechanisms, each single-side mechanism comprises a barrier plate, a plurality of through holes matched with the opposite-pull screw rod are formed in the barrier plate along the length direction, the opposite-pull screw rod penetrates through the through holes, and the opposite-pull screw rod penetrates through the through holes. Nuts matched with the opposite-pull screw are screwed into the two ends of the opposite-pull screw. According to the gap plugging device for modular wall construction, gaps in the two sides of a modular wall are plugged through the oppositely-arranged single-side mechanisms correspondingly, and the oppositely-arranged single-side mechanisms are fixed through the opposite-pull screws, so that the blocking plate can bear vibration without displacement. 本实用新型涉及一种模块化墙体施工用堵缝装置，包括相对设置的单
