Precast concrete board and superstructure are connected to absolutely dry formula

The utility model provides a method of absolutely dry formula is connected precast concrete board, superstructure and anti -seismic performance and is promoted. Concrete slab is including prefabricated concrete slab, and top both sides embedded plate push up the built -in fitting, and built -in fitting at the bottom of the board is established to the bottom, and board top built -in fitting includes board top anchor slab, connects exposed board and push up the dowel on the anchor slab of board top, the built -in fitting includes reinforcing bar at the bottom of the horizontal board at the bottom of the board, is connecting pre -buried metal sheet on the reinforcing bar at the bottom of the horizontal board, is equipped with reinforcing bar at the bottom of vertical board between the pre -buried metal sheet, and the metal sheet exposes in the board basal surface of precast concrete board. The superstructure includes and connects the floor that the concatenation of precast concrete board formed by absolutely dry formula, is connected with the roof beam around the floor. The utility model discloses a to the welded connection of built -in fitting at the bottom of the corresponding board in the position in the adjacent absolutely dry formula connection precast concrete board, regulation and control nodal connection's deformability, the deformability of built -in fitting is greater than board top built -in fitting at the bottom of messenger's board.
