Anti-cracking and plastering-free prefabricated light partition wall strip plate

The invention discloses an anti-cracking and plastering-free prefabricated light partition wall strip plate, and belongs to the technical field of non-bearing partition wall engineering. The anti-cracking and plastering-free prefabricated light partition wall strip plate comprises a partition wall strip plate body; vertical prefabricated mortar storage grooves are formed in the two side faces of the partition wall strip plate body in the height direction; a plurality of partitions are integrally prefabricated in the vertical prefabricated mortar storage grooves, and the height of the partitions is smaller than the depth of the vertical prefabricated mortar storage grooves; and joint grooves are formed in the two sides of the partition wall strip plate. According to a wall spliced by the strip plates, the vertical prefabricated mortar storage grooves in the spliced positions are compactly filled with mortar to form secondary connecting bodies with the inner bolt effect to be fixedly connected; through the part
