DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a metal glass door widely used in general houses and condominiums, and particularly a door having a large number of decorative windows, which is suitable for use as an entrance door. It is about.

[0002]

2. Description of the Related Art Conventionally, a large number of metallic glass doors widely used in general houses and condominiums have been proposed, but a large number of decorative windows suitable for use as entrance doors are provided. There have been few proposals for doors, including their manufacturing methods. For this reason, doors with a large number of decorative windows are manufactured in the same way as in the case of manufacturing a conventional general door, for example, after the front and back plates are fixed to the door frame by welding, etc. After filling the space with a suitable filler such as heat insulating material, and attaching a frame for windows to the front and back plates,
It is manufactured by equipping a glass plate through the packing attached to the picture frame.

[0003]

The above-mentioned conventional manufacturing method has a disadvantage that assembling is time-consuming and requires a lot of man-hours, and furthermore, the use of a frame or the like increases the material cost.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, and uses a front / back plate provided with an opening instead of a picture frame and further assembles the same. It is an object of the present invention to solve the above-mentioned problems by drastically improving the method and simplifying the assembly.

According to the present invention, a back plate provided with a plurality of back openings provided at required positions and having a holding portion formed by cutting into one side surface at a predetermined height is formed into a U-shaped cross section. After fixing the bent frame material to any one surface or back surface of the door frame body fixedly formed in a square shape, the holding portion is fixed inside with an appropriate adhesive material, and then the holding member is inserted through the holding portion. A locking member is fitted into each back opening from the inside, and a glass plate covering all of the back opening is superimposed on the inside of the locking member, and then formed symmetrically with the back plate. The front plate, the holding member is fitted to the front opening via a holding portion, the front opening is opposed to the back opening, and the holding member is brought into contact with the glass plate, After being fixed to the other surface or the front surface of the door frame with an appropriate adhesive, both surfaces of the door frame are held at a predetermined temperature for a predetermined time while being pressed at a predetermined pressure. Optionally a door process with multiple decorative windows, characterized in that the shape-forming by allowed to cure for a predetermined time cold holding to adhesive.

[0006]

According to the present invention, since the doors are assembled by sequentially stacking the constituent members having a simple structure, the respective assembling operations can be performed extremely easily, and the assembling procedure can be performed without difficulty. Does not occur, and the number of assembling steps can be significantly reduced as compared with the conventional manufacturing method.

Further, the present invention provides a table for forming a decorative window.
The use of front and back plates with back openings and pressing / locking members that decorate both openings and hold the glass plate reduces material costs and assembly man-hours compared to conventional manufacturing methods. Can be measured.
