Door and window unit auxiliary frame structure and mounting method of unit door and window

Abstract

The invention provides a door and window unit auxiliary frame structure and a mounting method of a unit door and window. The door and window unit auxiliary frame structure comprises a bottom auxiliary frame structure, two-side auxiliary frame structures and a top auxiliary frame structure, wherein the bottom auxiliary frame structure and the two-side auxiliary frame structures are same in structure, and comprise expanding bolts connected with functional auxiliary frames, the functional auxiliary frames and mounting pieces; the functional auxiliary frames are profiles which are in integral structures, and are made of polymer composites; each functional auxiliary frame consists of a narrow bottom board, a wide top board, an outdoor inclined board and an indoor inclined board which are located between the narrow bottom board and the wide top board, and a vertical baffle which is located between one side, close to the interior of a room, of the wide top board and the upper end of the indoor inclined board; the top auxiliary frame structure comprises an expanding bolt connected with a top auxiliary frame, and a groove-shaped auxiliary frame; and the groove-shaped auxiliary frame is a profile which is in an integral structure, and is made of a polymer composite. According to the door and window unit auxiliary frame structure and the mounting method, mounting of a complete window unit can be achieved; the difficulty of on-site construction is reduced greatly; and a construction period is shortened.

Description

technical field [0001] The invention relates to a frame structure for building doors and windows, and a method for installing the doors and windows using the frame structure. Background technique [0002] For the installation of building doors and windows on the building wall, most of the existing methods are to first set the building reserved openings, and then install the building doors and windows on the building reserved openings. There are two ways to install doors and windows in existing buildings: 1. Dry installation, that is, first install the attached (sub) frame and then install the door and window frame; 2. Wet installation, that is, directly install the door and window frame. [0003] The dry installation is to first fix the attached (auxiliary) frame with the wall by using a fixing piece, nails or expansion bolts, and then use self-tapping screws or self-tapping self-drilling screws to connect the door and window frames to the auxiliary (auxiliary) frame.
