Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of a doorway with a hinged door provided on a peripheral wall of a prefab room.

(Prior Art) A so-called prefabricated room in which an interior coating of a building body is prefabricated as a room structure building generally has a structure in which wall panels are lined up to surround a peripheral wall and the whole is covered with a ceiling.

The entrances and exits of such prefabricated rooms usually consist of openings in the peripheral wall, which are often fitted with hinged or catch doors.

Then, normally, the built-up height of the hinged door is set according to the inner height of the opening, that is, the clearance for rubbing is secured.

However, conventionally, the inner height of the opening is made to be substantially the same over the entire depth.

(Problems to be solved by the invention) In other words, the lower surface area of the upper edge of the opening was substantially flush with each other.
When connecting the openings of two prefabricated rooms to provide an entrance / exit, if the internal height of one opening is lower than the internal height of the other opening, the internal height of the other opening is also the depth. There is no choice but to lower it to the same height as the inner height of one of the openings, and as a result, the building height of the hinged door that fits this connected opening changes, so the length of the hinged door itself changes. There was a problem I had to do.

The present invention has been made in order to effectively solve the problems in the conventional entrance / exit structure of a prefabricated room. The purpose of the present invention is to open two adjacent prefabricated rooms in the building body. When connecting the doors to provide an entrance / exit, even if the internal height of one opening is lower than the internal height of the other opening, the entrance / exit of the prefabricated room does not need to change the height dimension of the hinged door itself of the connected opening. It is in providing structure.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an opening upper frame in a prefabricated doorway structure in which an opening is provided in a peripheral wall of a room and a hinged door is fitted in the opening. Has an upper part on the indoor side in side view and a lower part hanging from the upper part and located on the outer side of the room,
The inner height of the outdoor side opening from the lower part of the upper frame to the lower frame is made lower than the inner height of the indoor side opening from the upper part of the upper frame to the lower frame. A hinged door was installed on the.

(Operation) According to the above means, the building height of the hinged door can be matched with the inner height of the opening on the indoor side. When connecting the openings of two adjacent prefabricated rooms in the building structure to provide an entrance / exit, the inside height of one of the openings is not changed and Regardless of the difference between the height of the law and the height of the opening of the other prefab room,
It is sufficient to match both openings as they are, without changing the building height or length.
