Description

Construction and remodeling door frame}

The present invention relates to a door frame for construction and remodeling, and more particularly, to a door frame for construction and remodeling in which the door frame can be easily rebuilt in the form of padding without removing the existing door frame.

In general, in order to install a door at a construction site, a door frame made of a material such as 24T Laminated Veneer Lumber (LVL) for construction is installed at the location where the door is to be installed, and then the door is installed.

In addition, houses that are more than 20 years old often have scratches on the door frame installed in each room, or are old and unpleasant even if they are not greatly damaged, and many repairs or remodeling are performed to make these scratches or appearances look good. have.

A door frame used in such a construction site or a conventional door frame requiring repair is integrally formed, and a concave door leaf support portion is formed in the door frame itself, and the door leaf support portion is supported by the door leaf support portion.

As described above, in order to replace the newly installed door frame and door in accordance with the interior interior or to improve the old door frame, there is a method of replacing or repairing the door frame itself. However, when replacing the door frame as described above, After the door frame is dismantled, a new door frame must be manufactured and rebuilt. Therefore, the floor work and the wallpaper work are performed simultaneously, which increases the construction scope of the door frame, so not only the residents must relocate during the construction period, but also the construction of the door frame. There was a disadvantage that it was expensive.

So, until now, the method of repairing the door frame has been repaired only by performing surface treatment work on the damaged part of the existing door frame with a surface supplement, and then painting the surface of the door frame or attaching a film.

However, in the case of painting work, there was a problem that the residents had to leave the house during the construction period due to the harmful components of the paint while causing inconvenience to the residents due to the long-term occurrence of paint odor.

In addition, in the case of the method of attaching the film, the surface treatment is the same, but due to the difference between the material of the film and the material to which the film is attached, the difference in expansion coefficient, etc., the adhesion state does not last for a long time and is peeled off or the durability of the film itself is insufficient. Therefore, there were still disadvantages that were inappropriate for use for a long period of time.

As a prior document to solve the above problems, "Construction and Remodeling Door Frame Cover" of Korean Utility Model Registration No. 20-0322798 (Announcement on August 14, 2003) is bent and horizontally extended to cover the inner and outer edges of the family door frame. In the construction and remodeling door frame cover consisting of an inner and outer door frame cover made of a part and a central door frame cover coupled to an upper portion of the inner and outer door frame cover, the length is adjusted according to the width of the family door frame to be finished and installed, The outer door frame cover is of the same shape, and a groove is formed at the inner edge of the bent part to keep the conciseness with the family door frame, and a support part protrudes from the horizontal extension part extending to the bent part. The side is formed with an inclined to prevent separation inclined to the inside, and a fitting groove is formed along the longitudinal direction on the opposite side thereof, and a shock absorbing member is inserted into the fitting groove of one door frame cover among the inner and outer door frame covers, and the inner door frame cover It is characterized in that the central door frame cover formed with a fitting inclined surface corresponding to the separation preventing slope is fitted between the and the outer door frame cover.

If the width of the existing door frame is wide, it can be installed by adjusting the width of the central door frame cover while the outer door frame cover is installed. However, if the existing door frame is narrow, the length of the outer door frame cover is adjusted again by cutting. Since the central door frame cover must be installed after adjusting its width by cutting, etc., there is a hassle of work.

In addition, when the width of the existing door frame is wide, the central lower portion of the central door frame cover installed between the outer door frame covers is installed in a form that is floating in the air, so it has a problem that may be damaged when stepped on with a foot.
