Description

Prefabricated Door Frames {FABRICATING DOOR FRAME}

The present invention relates to a prefabricated door frame, and more specifically, without using a taka, by fixing the door frame using hot melt does not leave a mark of the takapin remains beautiful appearance, it is possible to improve the quality of the door frame, The cap and the second cap is formed of PVC or wood flour material, and relates to a prefabricated door frame for facilitating the assembly work by fixedly coupled to the frame by chamfering the inner edge.

In general, an opening having a constant width and height is formed in a wall of a building, a door frame having a rectangular frame structure is installed along the inner circumference of the opening, and the door is installed to be opened and closed.

Such a door frame is made in advance in a rectangular frame structure is constructed in the opening, or is constructed while assembling in the opening is a general structure.

In the prior art of constructing the door frame in a prefabricated manner as described in the Republic of Korea Patent Publication No. 10-2004-0079864 "door frame and its construction method" has a certain width and height to facilitate the user's access to the wall of the building An opening is formed, and in forming the door frame in which the door is provided on the inner wall surface of the opening, it is provided as a mortar on the wall and forms a rolling prevention groove in which mortar is filled at a predetermined interval on the bottom thereof, and on one side of the upper surface thereof. A core member forming a coupling groove and at least one installation groove on one side of the coupling groove; A reinforcing member on the bottom of the upper surface in close contact with the core material and forming a coupling jaw corresponding to the coupling groove of the core material to prevent its flow; A decorative frame body formed on the upper surface of the core and having a fixing jaw formed at the bottom thereof in order to prevent the flow of the core material and to accurately install the core in response to the installation groove of the core; A decorative member installed on one side of the core material and the decorative frame for aesthetic beauty; And the like.

In addition, the Republic of Korea Patent Publication No. 10-0388547 "Variable door frame" in the main frame member to cover the front part of the frame to be installed on the wall width front side, and each side of the main frame member coupled to the side of the frame of the frame In the variable door frame made of a finishing material to cover the finish, an insertion protrusion is formed on the rear side of the bent piece is bent from the extension piece is formed from the extension groove is formed on one side of the bent portion having a guide groove on the rear side and protruding jaw extending from the bent piece The second main member for the first jujube member having a second groove member is formed with a coupling groove is formed on the front side extending to one end and located in the guide groove on the rear side of the curved portion, and the extension portion formed with the bent portion and the stepped to the other end integrally. And a first groove formed at one end of the rear side to surround the protruding jaw of the first bending member bending piece, and one side of the rear side of the guide groove. The second finishing material is formed with a guide groove coupled to the extension part of the second jug member, and the rear end coupling groove of the first jug member and the front side coupling groove of the second jug member are forcibly fitted into the first, 2In a diagonal direction from the lower side of the main body to be fitted into the insertion groove between the coupling member is formed integrally formed in both directions for coupling the member for the main body, and the extension piece extending on the horizontal line from the first bending member member It is proposed to be a mold material having an insertion fixing portion formed.

In addition, the Republic of Korea Patent Publication No. 10-0728742 "Prefabricated door frame and its construction method" is installed along the inner surface of the opening formed in the wall of the building, the insertion groove is formed on the inner surface, the first insertion slit at both ends Main frame members each formed; A door stopper having a second insertion slit formed at both ends thereof, the outer surface of which is inserted into the insertion groove, and both ends of the inner part of the second insertion slit fixed to the main frame member by takapins; A pair of cap members installed to cover both inner surfaces of the main frame member and taka pins with one end inserted into the second insertion slit, and attached to the door stopper and the main frame member with an adhesive; And, as long as the third insertion slit corresponding to the first insertion slit is formed on the inner side, and fixed to the side of the main frame member and the cap member by a cross-shaped fixing bar in which both wings are inserted into the first insertion slit and the second insertion slit. And a pair of casing members.

Such conventional techniques are fixed and combined by assembling each using a fixing nail, or fixed using a tool such as taka, and then using a finishing material and a cap member so that the ta pins are not exposed to the outside, And there was a problem that the appearance is not beautiful due to the inconvenience of the maintenance after removing the pin and the marks left by the removal of the fixing nail and takapin, the space created by the fixing nail and takapin.

Therefore, the present invention has been proposed to improve such a conventional problem, without using a taka, by fixing the door frame using hot melt does not leave a mark of takapin remains beautiful appearance, it is possible to improve the quality of the door frame, The present invention provides a prefabricated door frame of a new type for facilitating the assembly work by chamfering the inner edges of the first cap and the second cap to the frame.

According to a feature of the present invention for achieving the above object, an opening is formed in the wall of the building to facilitate the user's access, the frame 20 is installed along the inner circumference of the opening, the frame 20 In the prefabricated door frame in which the door 100 is installed on the inner wall of the door), the frame 20 has a front face 22, a rear face 24 and a side face 26, and is formed inward from one side face 26a.
