Description

TECHNICAL FIELD [0001] The present invention relates to a door frame and a door frame having a door frame detachable structure,

The present invention relates to a door frame having a door detachable structure, and more particularly, to a door frame having a door detachable structure, more specifically, a door frame and a door frame are installed at a doorway of a building, To a door frame and a door frame construction method having a door frame detachable structure that is configured to install the door frame on the door frame.

As we all know, when constructing various buildings such as apartment buildings, the construction work will be done after the frame construction. In the indoor construction, the construction work will be done to install the door frame to install the doors first.

The structure of the conventional door frame for installing the door as described above is manufactured by integrally fixing the door frame and the door frame in the door frame manufacturing factory.

Therefore, it is inevitable to construct the door frame and the threshold area at the same time when the indoor construction is performed after the frame construction of various buildings such as apartments, and then to perform the indoor construction.

However, in order to carry out indoor work, a hand cart for transporting the material is used, and a variety of equipment such as a lift is moved for ceiling construction.

As described above, when the work using the hand cart or the lift is performed, the handrail or the lift hits the rim of the door frame that is installed first, so that not only a lot of inconvenience occurs but also the time for moving the equipment is delayed. Is becoming a factor to be prolonged.

In order to prevent the door frame constituting the door frame from being damaged in the course of various operations, the door or plywood is covered with the door frame. However, when moving a material such as a hand truck or moving a device such as a lift, Damage cases are occurring frequently.

In addition, there is a lot of cases in which construction is repeated due to the occurrence of a gap in the doorway due to an impact on the doorway, so that the door frame integrated door frame has many problems in performing various works in the interior construction.

Korean Patent Publication No. 10-2005-0112378 (published on November 30, 2005) Korean Registered Patent No. 10-1309734 (registered on September 11, 2013)

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a door frame which can be manufactured by assembling a door frame and a rim of a door frame, constructing a door frame and a rim of the rim, It is possible to smoothly move the equipment such as a handcart or a lift when the room construction is performed without colliding with the threshold so as to shorten the construction period and prevent the door frame constituting the door frame from being damaged in the course of the indoor construction The purpose is to make it possible to do.

In the case of constructing the door frame having the door detachment structure according to the present invention, the door frame mounting grooves are formed in the lower portions of both frames of the door frame so that the door frame can be installed. And a strong anchor bolt fastened to the female screw body embedded in the concrete floor and having a retaining nut is coupled to the anchor bolt coupling groove.

A method of constructing a door frame having the above-described door frame detachment structure includes steps of: disposing a door frame and a door frame at an entrance and exit of a wall, and then separating the door frame and the door frame; And a step of fastening a strong anchor bolt after the interior work and installing a doorpost, fixing the floor anchor bolt with a support nut, and finishing the floor finishing, is characterized by the present invention.

According to the present invention as described above, since the door frame is constructed by installing the door frame, the door frame is separated, and the door frame is fixed to the door frame after the interior construction is completed, There is an effect of providing a convenience of being able to work smoothly,

In addition, not only can it contribute to shortening the construction period, but also it is possible to prevent the door frame constituting the door frame from being damaged during the work process, and to solve the problem of causing a safety accident by hitting the door with the operator. It is an expected invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A door frame and door frame construction method according to the present invention will be described in detail with reference to the accompanying drawings.

In the case of constructing the door frame having the door frame detachment structure according to the present invention, the door frame mounting grooves 12 are formed at the positions where the door frame is installed below the frames 11 of the door frame 10, Respectively,

The door frame 1 constructed as described above is installed at the entrance of the wall and the anchor bolt coupling groove 2 is formed at the bottom of the door frame 1 to be installed in the doorway installation groove 12, And a strong anchor bolt 20 provided with a support nut 21,

A door leaf cover 4 composed of a metal plate is mounted on the door handle 1 and is fixed to the concrete floor 30 with fixing nails through holes 5 formed on both sides.

In the drawings, reference numeral 50 denotes a female thread tube for fastening a strong anchor bolt, 51 a wall, and 52 a bottom finishing plaster.

The operation of the door frame having the door detachment and attachment structure according to the present invention and the door frame construction method will be described in detail as follows.

The operation of the door frame for removing the door handle detachable structure according to the present invention will be described.

According to the present invention, since the door frame is provided at the entrance and exit of the wall body 51 in a state where the door handle 1 is installed in the doorway installation groove 12 formed at the lower portion of the frame 11 of the door frame 10, So that it can be installed accurately and accurately at the entrance.
