Window frame body

Abstract

The window frame involves building component products. The window frame includes an inner frame aluminum material, a frame material plastic material and an outer frame aluminum material. Close to the outer wall, cover part of the outer wall of the hole, fix the angle steel sheet in the "T" groove of the overhanging part of the four sides of the outer frame aluminum, and use expansion bolts (or expansion nails, expansion plugs) to seal the window The frame is fixed in the opening, filled with foaming agent and coated with solid wall glue to seal. The invention of the invention enhances the attachment and installation strength of the window frame and the wall, and has great wind pressure resistance, water permeability prevention and heat preservation effect. It has the characteristics of good window quality, simple installation process, high construction efficiency and excellent performance indicators.

Description

technical field [0001] The invention relates to a building component product, which is a window frame configured and installed in a civil construction opening. Background technique [0002] At present, the connection and installation of the opening window and the wall in housing construction generally adopts the installation of fixing parts around the frame material; Within the containment of the wall, there is no extension protection structure on the four sides of the opening. In many years of production practice, the shortcomings and deficiencies exposed by this window frame body and its installation structure are very obvious. First of all, the connection method of the conventional fixing parts is unreasonable, the strength is not high, and it cannot meet the real fixing strength requirements; secondly, due to the intersecting work between the civil construction and the installation of the window frame, mutual constraints prevent the finished product of the window frame ...

Problems solved by technology

In many years of production practice, the shortcomings and deficiencies of this window frame body and its installation structure are very obvious

First of all, the connection method of the conventional fixing parts is unreasonable, the strength is not high, and it cannot meet the real fixing strength requirements; secondly, due to the intersecting work between the civil construction and the installation of the window frame, mutual constraints prevent the finished product of the window frame from leaving the factory. All of them leave the factory as semi-finished products. Not only is it difficult for the factory to form large-scale production, but it is difficult to guarantee product quality, and it is time-consuming and labor-intensive to install, which increases the installation cost. Third, the installation of the original window frame structure and the opening is a through-seam connection. When the temperature difference changes greatly, the coefficients of thermal expansion and contraction of the window frame and the wall are different, and it is easy to produce hidden seams and ventilation, and the thermal insulation effect is poor; In the side walls of the four sides of the opening, the fixed attachment surface is small, the wind pressure resistance is low, and the rainwater permeability is poor. Especially with the increasing number of high-rise buildings, the low wind pressure resistance has become its main technical problem

Fifth, the window frame of the existing structure must destroy the wall during house repair, interior decoration or replacement, otherwise it cannot be disassembled and assembled, which brings a lot of inconvenience to users
