Description

[Detailed description of the invention] 【Technical field】

The present invention relates to the structure of a renovated entrance door frame for attaching a new entrance door frame while leaving the existing entrance door frame intact.

[Background technology]

Conventionally, in order to renovate an entrance door frame, the existing entrance door frame was removed and a new entrance door frame was installed in its place. However, with this method, the work to remove the existing entrance door frame is complicated and large-scale, and in particular, the outer wall, inner wall, floor tiles, etc. around the existing entrance door frame have to be demolished, and the work is done again by Mf & around the new entrance door frame. There was a problem in that the outer walls, inner walls, floor tiles, etc. had to be repaired, and the cost was also high.

[Purpose of the invention]

The present invention was invented in view of the above-mentioned conventional problems, and its purpose is to enable installation of a new entrance door frame without destroying external walls, internal walls, floor tiles, etc., and to simplify construction. In addition, if the lower frame of the existing entrance door frame is left and the new entrance door frame is placed on top of it, the lower frame cover material will be lower than the floor surface on the indoor side in relation to the door stop, etc. To provide a structure of a renovated entrance door frame that protrudes upward from the wall but allows easy drainage of water from the floor surface on the indoor side to the outdoor side.

[Disclosure of the invention]

The structure of the entrance door frame of the present invention is such that a new entrance door frame 2 is disposed on the inner periphery of an existing entrance door frame 1, and a new entrance door frame 1 is installed.
A lower frame cover material 3d is provided extending from the newly installed lower frame 2C to the floor surface 11 on the indoor side and protrudes upward from the newly installed lower frame 2C and the indoor floor surface 11, and this lower frame cover material 3d It is characterized by being provided with a water drain section 14 that communicates from the floor surface 11 on the indoor side to the outdoor side, and by adopting such a configuration, the above-mentioned object of the present invention is achieved. It is. That is, in the present invention, as described above, a new entrance door frame 2 is installed with the existing entrance door frame 1 left in place, so there is no work required to remove the existing entrance door frame and the external and internal walls associated with this. , work to destroy floor tiles, etc., work to repair outer walls, inner walls, floor tiles, etc. is no longer necessary, and the new lower frame from the new lower frame 2C of the newly installed entrance door frame 1 to the floor surface 11 on the indoor side is no longer necessary. 2C and indoor floor surface 11
The lower frame cover material 3d is disposed to protrude upward from the lower frame cover material 3d, and the lower frame cover material 3d is provided with a water drain portion 14 that communicates from the floor surface 11 on the indoor side to the outdoor side.
d is provided, water can be easily drained from the floor surface 11 on the indoor side to the outdoor side. The present invention will be explained in detail below with reference to Examples. The existing entrance door frame 1, which is fixed to the opening of the building, has the door and transom removed, and the mullions and mullions removed, and the existing vertical frame 1a, the existing upper frame 1b, and the existing lower frame IC Only the following will remain. Next, the liner 8 is fixed to the existing vertical frame 1a and the existing upper frame 1b of the existing entrance door frame 1.Next, a new entrance door frame 2 is attached to the inner circumference of the existing entrance door frame 1. set,
It is fixed to the main liner 8 or the existing entrance door frame 1 using fixing devices such as screws. Existing entrance door frame 1
The space between the door frame 2 and the newly installed entrance door frame 2 is covered with a cover material 3. In the illustrated embodiment, the cover material 3 includes an outdoor decorative cover material 3a having an uneven shape, and an indoor cover material 3C1 and a lower frame cover material 3d having a rounded cross section. In this case, first, the outdoor side decorative cover material 3a and the indoor side cover material 3C are attached. Here, the gap between the outdoor decorative cover material 3a and the outer wall 9,
Alternatively, the caulking agent 13 is filled in the gap between the indoor cover material 3C and the picture frame 10 as necessary. After that, the lower frame cover material 3d is fixed. The lower frame cover material 3d is stretched from the new lower frame 2C to the floor surface 11 on the indoor side, and is fixed to the existing lower frame 1c with screws 15 so as to cover the rear upper surface of the existing lower frame 1c. It is. In this case, of course the doorstop part 17 of the existing lower frame 1c
Since the door stop 16 protruding from the rear upper surface of the newly installed existing bottom frame 2C is located above, the door stop 16 will protrude above the floor surface 11 on the indoor side. 16 and the front upper surface of the lower frame cover material 3d, the lower frame cover material 3d is also located above the floor surface 11 on the indoor side. The rear part of the lower frame cover material 3d is inclined downward. Holes and grooves are provided at both ends of the lower frame cover material 3d to form water draining portions 14. Here, the doorstop part 16 is either not present in the part corresponding to the water drain part 14, or a hole or a groove is provided in the part corresponding to the water drain part 14. By doing so, water can be drained from the floor surface 11 on the indoor side to the outdoor side through the water draining part 14 of the lower frame cover material 3d. The door stop 16 mentioned above is the existing lower frame 2C
The door stop 16 may be formed integrally with the front part of the lower frame cover material 3d without being provided on the lower frame cover material 3d.By the way, the existing frame 10 may be left as is without being removed. When the indoor side cover material 3c is attached to the newly installed entrance door frame 2, the end of the indoor side cover material 3c comes into contact with the frame 10. Furthermore, the floor surface 11 on the indoor side is of course left in place without being removed.In the embodiment shown in the drawing, tiles are shown as an example of the floor surface 11 on the outdoor side. Note that 12 is a pillar of the building. Also, 2 in the diagram
A is a newly installed vertical frame, and 2b is a newly installed upper frame.

【Effect of the invention】

In the present invention, as described above, a new entrance door frame is installed on the inner periphery of the existing entrance door frame, so the new entrance door frame can be installed without removing the existing entrance door frame. Entrance door frames can be installed, and as a result, there is no need to destroy external walls, internal walls, floor tiles, etc. due to removing the existing entrance door frame, and it is also possible to repair external walls, internal walls, floor tiles, etc. afterwards. This method simplifies the work and reduces costs, as there is no need to do any additional work, and it also reduces the cost. A lower frame cover material is provided that protrudes upward from the lower frame cover material, and this lower frame cover material is provided with a drainage part that communicates from the floor surface on the indoor side to the outdoor side.
Even though a lower frame cover material is provided that protrudes above the floor surface on the indoor side, water can be easily drained from the floor surface on the indoor side to the outdoor side.
