Combined model framework for road and bridge design

The invention discloses a combined model framework for road and bridge design, which comprises a support column with a positioning hole on one side of the outer surface, a fixing column with a pressing rod penetrating through one end in a threaded manner, and a connecting hole with a cable inserted into the inner wall, and a cross beam for supporting is inserted into one side of the support column. The top of the supporting column is fixedly connected with a limiting block used for limiting, and the outer surface of the limiting block is sleeved with a connecting column used for connecting and fixing. According to the combined model framework for road and bridge design, through cooperative arrangement of the limiting blocks and the connecting columns, a supporting part and a hoisting part of the combined model framework can be installed step by step, so that one-time overall splicing is not needed, personnel needed for installing a model are saved, and through cooperative arrangement of the fixing plates and
