Embodiment Construction

[0021] The present invention is an improvement to the integral steel door frame; figure 1 It is a schematic diagram of the overall steel door frame structure and installation in the past; in the figure, 1 is the steel door frame, 2 is the fixing piece, 3 is the steel nail, 4 is the wall surface decoration layer, 5 is the right face line, and 6 is the left side Face line, 50 is the wall, and B is the direction in which the steel door frame is pushed into the doorway as a whole. The wall surface decoration layer 4 on the right side of the figure is halfway constructed, and the second step of construction can be carried out after the fixed piece 2 is fixedly connected with the wall 50 with steel nails 3, as shown in the left part of the figure. In order to push the whole steel door frame into the door opening, the left face line 6 must be lower than the door opening, and the right face line 5 is generally higher than the door opening, so that there is a difference in height in th...

Abstract

This invention relates to a combined steel door frame structure and installation method. It contains main door frame and sub door frame, first and second positioning slot in main door frame, first and second positioning tenon insertion connected respectively with first and second positioning slot to connect main and sub door frame, stop line is set on sub door frame. Said invention has advantages of easy installation, durable and fine prizing resistance.

Description

1. Technical field: [0001] The invention relates to a structure of a combined steel door frame and an installation method thereof. 2. Background technology: [0002] Steel door frames on the market are mostly one-piece structures, which mainly have the following defects: 1. Time-consuming and labor-intensive installation: the whole is pushed into the door opening during installation, and the fixing piece is installed. The fixing piece and the wall are connected by steel nails, and then As the surface decoration of the wall, cover the gap between the fixing piece, the steel nail and the wall and the door frame, and the surface decoration of the wall is mostly wet construction. 2. Poor prying resistance: As long as the surface decoration layer of the wall is partially destroyed to expose the fixing piece and steel nail, the entire door frame can be pushed into the room to separate it from the wall by removing the steel nail and fixing piece. 3. The height of the two face line...
