Detailed Description

Referring to fig. 1-3, the present invention provides a technical solution:

the utility model provides a civil engineering construction concrete built-in fitting, including mount pad 1, 1 bottom surface of mount pad is symmetrical structure and rotates and is connected with two and buries a board 2, it is equipped with adjusting part 3 to bury 2 inner walls of board, it has two tensile plates 4 to bury 2 both sides of board and be symmetrical structure articulated, it is connected with dwang 201 to bury 2 top surfaces of board to rotate, dwang 201 upper end is connected with 1 bottom surface rotation of mount pad, adjusting part 3 includes threaded rod 301, threaded rod 301 lower extreme outer wall passes buries 2 upside inner walls of board and is connected fixedly with dwang 201 bottom surface, threaded rod 301 rotates with buries a board 2 to be connected, threaded rod 301 outer wall threaded connection has movable block 302, movable block 302 outer wall and 2 inner walls sliding fit of board that bury, movable block 302 both sides articulate has vaulting pole 303, vaulting pole 303 outer end is connected fixedly through free bearing and tensile plate 4 medial surface.
