Abstract:
1. A pressure injecting caulking construction technique for gaps between building door/window hole and common additional frame or side frame, comprising the steps as follows: A. firstly, installing a common additional frame or side frame of a building door/window in a building door/window hole, and positioning the common additional frame or side frame of the building door/window; B. installing a combined framework on the sides of the additional frame or side frame of the door/window and a wall defining the boundary of the hole, so that the edge of the framework at one side of the combined framework abuts against an inner side face of a reserved hole on the wall and the inner side faces of the frameworks in the combined framework are attached to an outer side surface of the additional frame or side frame, wherein the combined framework in step B comprises forked fasteners and frameworks, the forked fasteners having multiple points, and one face of the forked fastener is provided with an adjusting mechanism so that the frameworks tightly press against the side face of the additional frame or side frame of the door/window; C. injecting a filling material into a gap between the building door/window hole and the common additional frame or side frame using mechanical pressure; and D. dismantling the combined framework after the filling material is cured or semi-cured.
