Strip plate inner partition wall door hole structure and inner partition wall

The invention discloses a strip plate inner partition wall door hole structure. The strip plate inner partition wall door hole structure comprises a prefabricated door head plate, prefabricated door frame vertical plates and prefabricated door frame vertical columns, and through design of the prefabricated door head plate, the situation that as for an existing strip plate inner partition wall doorhole structure, the door head plate is spliced at the corner in a door hole mostly prone to cracking is avoided; L-shaped notches are formed in the upper parts of prefabricated door frame vertical plate bodies, thus the prefabricated door head plate and the prefabricated door frame vertical plates are connected conveniently in a stagger-jointed engaging mode; prefabricated mortar storage groovesand joint grooves are formed in the outer side of the prefabricated door head plate, the outer sides of the prefabricated door frame vertical plates and the outer sides of the prefabricated door framevertical columns correspon
