DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the prior art, accurately mounting and installing the above-mentioned door frame was actually quite troublesome and required a lot of labor and time. That is, the door frame is generally manufactured as a gate type with the left and right vertical frames and the upper frame that is laid across between the upper ends of the vertical frames. The holding property was poor, and the mounting state was often inaccurate. For example, as shown by the chain line in Fig. 11 (a), the dimensions between the left and right vertical frames may become uneven, or the same figure (b)
The squareness between the vertical frame and the upper frame is impaired as shown by the chain line in Fig. 5, or both vertical frames are not in the same plane as shown by the chain line in Fig. (C), causing a twisted state, Furthermore, as shown by the chain line in FIG. 6 (d), the entire door frame tends to have a forward tilt or a rear tilt, and as a result, the accuracy of the door installation is likely to be impaired. .

For this reason, in the conventional installation and installation of the door frame, when fixing the vertical frame to the pillar on the body side, the parallelism of both vertical frames, verticality, perpendicularity between the vertical frame and the upper frame, etc. I had to fix it while repeatedly checking it with a tape measure, a tape measure, and a plumb bob, and also adding fine correction work each time. Therefore, as a matter of course, the installation work requires a lot of time and labor, and also requires skill, which is extremely troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and make it possible to more easily and accurately mount a door frame.

Means for Solving the Problems One of the inventions is, as a means for achieving the above-mentioned object, as a means for achieving the above-mentioned object, in the manufacturing stage of a door frame, the vertical and horizontal vertical frames are arranged parallel to each other at a plurality of upper and lower vertical positions. Degree and the perpendicularity to the upper frame are properly regulated and held, and the shape-retaining reference plate is attached in a temporarily attached state that can be subsequently removed, and the door frame can be attached at the installation stage of the door frame. The present invention provides a method for mounting and installing a door frame, characterized in that the reference plate is installed and fixed upright in the opening of a wall to be mounted, and then the reference plate is removed and removed.

Therefore, the present invention also provides, as a door frame assembly before installation used in the above-mentioned construction method, between the left and right vertical frames of the door frame, at a plurality of upper and lower positions, the parallelism of the both vertical frames and their upper frames. It is characterized in that a strip-shaped reference plate for shape-retaining that properly regulates and holds the right angle with respect to is attached to a temporarily attachable state that can be subsequently removed. In this case, it is assumed that the reference plate is installed in a temporarily fixed state by selecting a groove portion that is concealed after construction such as a door stop mounting groove and a frame mounting groove, which are provided in the left and right vertical frames of the door frame, as the mounting site Is desirable.

Since the reference plate is attached to the door frame in advance, the shape of the door frame, in particular the parallelism between both vertical frames and the perpendicularity between the upper frame and the vertical frame can be properly maintained until the reference plate is removed. . Therefore, while maintaining the mounting state of the reference plate, by mounting and fixing it on the wall side of a building, the parallelism
