Door and window external frame strongly connected to wall body and installation method for same

Abstract

The invention discloses a door and window external frame strongly connected to a wall body and an installation method for the door and window external frame. The door and window external frame comprises a lower frame body. A cavity is formed in an inner cavity of the middle of the lower frame body; filling slots are formed on two sides of the lower frame body; the filling slots are filled with foaming material fillers; the foaming material fillers are fixedly connected to the external side of the lower frame body and the wall body; necks are formed on two sides of the upper part of the lower frame body; the necks are movably connected to an upper frame body via a buckling device and a second buckling head; reinforcing ribs are disposed in the middle of an inner cavity of the upper frame body; guide rails are fixedly connected to the upper part of the upper frame body; water overflow gaps are formed on two sides of the guide rails; and a water discharging port is formed in the upper frame body. The door and window external frame strongly connected to the wall body is simply structured and easy and practical to use; doors and windows can be installed in place for one time, so finished doors and windows can be delivered to a user without damages; door and window production period can be greatly shortened; exchanges of the doors and windows later can be facilitated; and resource and cost can be effectively saved.

Description

technical field [0001] The invention relates to the technical field of doors and windows, in particular to a door and window outer frame with strong connection with a wall and an installation method thereof. Background technique [0002] With the rapid development of my country's construction industry, the quality and grade of buildings have also been greatly improved, especially the popularization of building energy-saving and external wall insulation technology, which urgently needs the standardization of building doors and windows and the integration of building energy conservation. However, the installation of building doors and windows is still completed by the technological process of leaving holes first, then installing the window frame, then caulking and painting around the doors and windows, and assembling the doors and windows. Due to the influence of various factors such as building formwork, pouring, and blocks during civil construction, the reservation of the op...

AI Technical Summary

Problems solved by technology

Due to the influence of various factors such as building formwork, pouring, and blocks during civil construction, the reservation of the opening cannot be fully standardized at one time, and it needs to be solved by manual plastering. The connection between the outer frame of the door and window and the wall Poor, time-consuming, labor-intensive and material-intensive, especially at present, labor wages have risen sharply, resulting in a substantial increase in costs

Moreover, in the process of painting and caulking around the inside and outside of the door and window openings, through the cooperation of multiple types of work, it will inevitably cause serious damage and pollution to the outer frames of the installed doors and windows. to no avail

And because the filling around the doors and windows is not dense, it is easy to cause problems such as leakage, and it also includes the connection and waterproof problem of the external wall insulation of the building and the installation holes of the doors and windows.
