Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to a door replacement structure in which an existing entrance door is replaced with a new one, and is particularly applicable to aging entrance doors, heat insulation, sound insulation, fire prevention, earthquake resistance. Regarding the existing entrance door replacement structure, which is replaced with a new door when upgrading for the purpose of.

[Prior Art] The current structure for replacing an existing entrance door with a new door involves removing the old frame from the building and fixing the new frame. According to this structure, replacing the frame requires a considerable amount of work, which takes time and effort, and has the drawback of increasing the construction effort.

Although it is not an entrance door, a new window frame structure has been developed in which an existing window frame is replaced with a new one by stacking the old frame on top of the existing frame without removing it from the building and fixing the new frame.

This structure is divided into two parts: the inside and outside of the window, and one part is fitted into the old frame from the inside of the window, and the other part is fitted into the old frame from the outside of the window, and both frames are inserted. The structure is such that they fit and connect each other.

Since the frame of this structure is connected by fitting the abutting edges of both frames into each other, the width of the frame in the connected state cannot be adjusted to match the thickness of the frame, and the overall width of the frame cannot be adjusted. , it was necessary to accurately adjust the width of the old frame, or to insert a spacer with a different thickness between the new frame and the old frame on the front side of the old frame. .

When installing a new frame onto an existing old frame, the old frame was not the same manufacturer or model, and most of the old frames had different widths.

In addition, most of these types of frames are made of steel processed into a fixed shape, so it is difficult to change the overall width to match the overall width of the old frame, and depending on the type of the old frame, There were some drawbacks such as not being able to install it. Furthermore, regarding the attachable frame, it was difficult to fit the new frame tightly to the inside of the old frame without any play, and there was a problem with the strength of the attachment.

In particular, entrance doors are heavier than windows, are opened and closed more frequently, and the impact when the door is closed is large, so it is important to firmly attach the new frame to the old frame without play. is more important than anything else.

By the way, a structure in which the door frame is divided into front and back parts, wrapped to the required width at the split point, and the width of the door frame can be varied by changing the width of the wrapped part is suitable for newly installed doors. It has been developed as a frame (see Utility Model Application Publication No. 48-68431 and
-5530 Publication).

However, since this door frame is not for modifying an existing door frame, it has the drawback that although it can be conveniently installed in a new building, it is difficult to use it to replace an existing entrance door.

[Purpose of invention]

This device was developed with the aim of eliminating the above-mentioned drawbacks of conventional replacement frames.The important purpose of this device is that the width can be adjusted during installation, and a single new door frame can be used. To provide a structure for replacing an existing entrance door with which various existing entrances of different types can be easily renovated.

Another important purpose of this invention is to provide a structure for replacing an existing entrance door in which a new door frame can be simply and easily, quickly and inexpensively installed along with the old frame without removing it. It is in.

[Means to solve conventional problems]

The existing entrance door replacement structure of this invention consists of an old frame fixed to the building frame and a new door frame for replacing the existing entrance door fixed inside the old frame.
The new door frame is divided into front and rear parts on the inner surface of the old frame body, wrapped at the split points over the required width, and fixed to the old frame body via screws that pass through the wrapped parts. , this lap portion is in a plane perpendicular to the front and rear surfaces of the old frame body. A Spencer is sandwiched between the old frame and the new door frame.
Furthermore, a groove is provided in the frame along the outer periphery of the old frame, and the outer periphery of the new door frame is bent toward the frame, and this bent edge is guided into the groove. Filled with caulking material.

By the way, in this specification, the old frame body and the new door frame 1
The front side of the frame means the outdoor side of the frame in the case of a peripheral door, and the rear side means the indoor side.

New door frame 1 divided into two parts: front frame 1a and rear frame 1b
is wrapped to a width of, for example, 10 to 30 mm at the split location, and is fixed to the old frame body 2 with a screw 4 passing through the wrapped portion 3.

The wrap portion 3 is arranged in a plane perpendicular to the front and rear surfaces of the old frame 2, that is, in a plane perpendicular to the front and rear surfaces of the old frame 2, so that the installation width of the new door frame 1 can be adjusted by adjusting the wrap width. It is formed into a planar shape parallel to the front-rear direction.

In FIG. 1, the outer peripheral edge of the front frame 1a is bent inward at right angles, and the bent edge 5 is provided with a groove 10 in the frame 11 along the outer periphery of the old frame. It is guided into the groove 10 and buried in the caulking material 6.

The periphery of the rear frame 1b is screwed to the building if necessary.

For example, there is a gap of several mm between the new door frame 1 and the old frame 2.
A thick metal spacer 7 is sandwiched therebetween. The spacer 7 is effectively used for fixing the hinge, lock, etc. of the door 8.

The new door frame 1 consists of a vertical frame and a horizontal frame connecting both ends of the vertical frame. Vertical frames and horizontal frames can be cut and connected at the factory to match the width and height of the old frame, or

〔effect〕

The door frame of the existing entrance door replacement structure configured as described above is divided into front and back parts, wrapped together and fixed to the old frame, so the old frame of the existing entrance door is removed from the building. It can be easily installed along this line without having to do anything, and the entrance door can be replaced simply and easily, quickly and at a low cost. is in a plane perpendicular to the front and rear surfaces of the old frame, and by adjusting the wrap width, the width of attachment to the old frame can be freely adjusted. For this reason, there is no need to manufacture door frames to match the width of the old frame.
Even though it is a type of door frame, it can be tightly attached to old frame bodies of different widths without any play, and achieves the excellent effect of completely and firmly fixing to almost all old frame bodies.

Furthermore, a noteworthy feature of this invention is that the new door frame, which is fixed to the outside of the old frame, is fixed to the old frame through a spacer, so the spacer connects the new door frame and the old frame. In addition to adjusting the gap between the base and the base, it can also be used as a reinforcing base to securely fix hinges, locks, etc. For this reason, even though the old frame remains inside, and there is a gap between the old frame and the new door frame for adjusting the distance, the door and lock etc. are not installed in the same way as the newly installed entrance door. It has the advantage of being able to be firmly fixed.

Furthermore, a groove is provided in the frame along the outer periphery of the old frame, and the bent edge of the new door frame is guided and caulked into this groove, so the wrap width of the new door frame can be adjusted to make it easier to connect it to the frame. In addition to adjusting the width to match the old frame, the installation position can be adjusted by adjusting the depth of insertion into the groove. Therefore, the degree of freedom in installing the new door frame is extremely large, and most existing entrances can be easily remodeled into new ones, and the boundary between the new door frame and the frame can be beautifully finished in the installed state. Therefore, the excellent feature that existing entrances of various shapes can be left as they are without removing the old frame and can be beautifully renovated simply and easily and extremely quickly can be achieved.
