Firm-structure weir type building structure based on building

The invention provides a firm-structure weir type building structure based on a building, and relates to the field of building structures. The problems that adjustment cannot be carried out accordingto the topographical condition, screw seats on a board room body are likely to be smashed and are inconveniently to repair in the process of hitting screws for fixing, and fast mounting and stabilitycannot be organically combined are solved. The firm-structure weir type building structure based on the building comprises longitudinal walls, and totally two longitudinal walls are arranged. The device is reasonable in structure and high in adjustability, and labor is saved during adjustment. Firstly, horizontal adjustment of the device can be achieved through a threaded rotary supporting seat ona rotary supporting structure; and secondly, due to the hollow structure of the supporting seat, the bottom of the supporting seat is rotationally connected with a base, a screw is inserted into thesupporting seat, and by arra
