Plastic fastener and assembled wall

Technical Field

The utility model relates to a building assembly technical field especially relates to plastics buckle and assembled wall body.

Background

The assembled wall body has two types, one type comprises an outer wall and an inner wall, and the other type comprises an outer wall, a heat preservation wall and an inner wall. Both types of assembled wall bodies are formed in a mould, normally: the mold forms the outer wall first, then the heat preservation wall is put into the mold (if the heat preservation wall does not exist, the step is omitted), and finally, the mold forms the inner wall.

The pumping mechanism pumps concrete into the mold to form the outer wall and the inner wall of the mold. During pumping, the cavity of the mold tends to expand outwardly under the pressure of the concrete. To avoid deformation of the cavity of the mold during pumping, a pushing force is typically applied to the mold plates (e.g., by a cylinder or a ram) that presses the mold plates against each other to counter the compressive force of pumping.

Since the assembled wall body comprises at least two wall panels, the mould is usually set to stepless adjustment. The stepless adjustment enables the die to form assembled walls with different sizes, but the stepless adjustment also brings the defect that the thickness and the size of the die cavity are difficult to control. The existing assembly type wall body comprises an outer wall, an inner wall and a connecting assembly, wherein the inner wall is positioned on the inner side of the outer wall and is provided with a steel bar structure; coupling assembling, including connecting rod and plastics buckle.
