Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door frame structure applied to a house or the like.

[0002]

[Background of device]

 As shown in Fig. 6, the door frame (1) is composed of both side frames (2, 3) and an upper frame (4), and in a house or the like, it is usually supplied to the site with the door attached. At the site, a construction method is applied in which the door is once separated, the door frame (1) is attached to the doorway of the building, and then the door is attached to the door frame (1) again.

When the door frame (1) is attached to the doorway of a building, the parallelism of the side frames (2, 3) and the perpendicularity of the side frames (2, 3) pose a problem. However, since the door frame (1) is easily deformed, the parallelism of both side frames (2, 3) and the squareness of both side frames (2, 3) should be repeatedly measured with various measures to correct it when installing. It is necessary to do this, which makes the installation work of the door frame (1) cumbersome.

[0004]

[Prior art]

 In order to eliminate the hassle when installing the door frame (1), the reference plate (7) is attached to both side frames (2, 3) of the door frame (1) as shown in FIGS. 6 and 7. ) Is provided (Japanese Patent Laid-Open No. 3-137387). As shown in FIG. 7, the reference plate (7) has its both ends attached to the door contact mounting grooves (2A, 3A) formed inside the side frames (2, 3) of the door frame (1). ) To fix the gap between the two side frames (2,3) at a constant interval, and thus fix the parallelism of the both side frames (2,3) and the side frames (2,3). It holds the squareness of the upper frame (4). In the above door frame (1), attach the reference plate (7) to the doorway of the building with the reference plate (7) attached, then pull out the nail (9) and cut the reference plate (7) in the middle with a saw or the like. Remove it.

[0005]

[Problems to be Solved by the Invention] However, in the above-mentioned conventional configuration, with the mounting bar (8) adhered to the reference plate (7) with an adhesive or the like, the door stop mounting groove is installed from the lower side of the door frame (1). When both ends are fitted into (2A, 3A) and slid upward and fixed in place with nails (9), it takes time to install the reference plate (7), and when removing the reference plate (7) Even this requires cutting with a saw, which is troublesome. The material of the reference plate (7) must be a material that can be cut by a saw such as wood, and such a material is easily deformed by temperature, humidity and external force, and the parallelism of both side frames (2, 3) and The squareness of the side frames (2, 3) with respect to the upper frame (4) is not reliably maintained.

[0006]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention is a door formed inside both side frames (2,3) of a door frame (1) consisting of both side frames (2,3) and an upper frame (4). The mounting bar (18) mounted at a predetermined position in the contact mounting groove (2A, 3A) and the both ends that are passed between the mounting bar (18) and fixed to the mounting bar (18) with fasteners (19) The fixed pier (17) and the fixed pier (17) parallelize the side frames (2, 3) and the perpendicularity of the side frames (2, 3) to the upper frame (4). It is intended to provide a door frame structure holding the.

[0007]

[Action]

 The door frame (1) consists of both side frames (2,3) and an upper frame (4), and the predetermined position of the door stop mounting groove (2A, 3A) formed inside the both side frames (2,3). The mounting bar (18) is attached to the mounting bar (18) and both ends of the fixing bar (17) are fixed to the mounting bar (18) by the fasteners (19). In this way, the fixed crosspieces (17) passed between the two side frames (2, 3) via the attachment crosspieces (18) keep the distance between the both side frames (2, 3) constant. When removing the fixed pier (17), the fastener (19) is removed without cutting the fixed pier (17) with a saw or the like, and the fixed pier (17) is removed from the mounting pier (18). After that, remove the mounting bar (18) from the door contact mounting grooves (2A, 3A) on both side frames (2, 3).

[0008]

【Example】

 1 to 5, the door frame (1) comprises side frames (2,3) and an upper frame (4), inside the side frames (2,3). And the door stop mounting grooves (2A, 3A, 4A) are formed inside the upper frame (4). Mounting bars (18) are attached to both ends of the fixed beam (17) that is passed between the both side frames (2, 3) of the door frame (1) by fasteners such as nails (19) or screws. In addition, a reinforcing beam (20) is installed in the central part.

The fixed rail (17) is passed between the side frames (2, 3) via the mounting rail (18) by fasteners such as nails (21) or screws. That is, the mounting bar (18) is fitted in the door stop mounting grooves (2A, 3A) of the side frames (2, 3) and is mounted at a predetermined position by the nail (21). In order to transfer the above-mentioned fixed pier (17) between both side frames (2, 3), attach the mounting bar (18) to the fixed pier (17) and then transfer it between both side frames (2, 3). Even if the mounting bar (18) is first mounted in the door contact mounting grooves (2A, 3A) of the two side frames (2, 3) and then the fixed bar (17) is mounted on the mounting bar (18). Good. In any case, the fixed rail (17) is nailed or screwed to the portion of the mounting rail (18) that goes out from the door stop mounting groove (2A, 3A). In this way, the spacing between the side frames (2, 3) is kept constant by the fixed crossbar (17) via the mounting bar (18), and therefore the parallelism of the side frames (2, 3) and the side frames (2, 3) are maintained. The squareness between (2,3) and the upper frame (4) is maintained.

As shown in FIG. 3, the door (5) is fixed to the side frame (2) of the door frame (1) on the side of the fixed edge (5A) of the door (5) via a hinge (6). An edge (5A) is attached and the free edge (5B) of the door (5) is fixed by a stopper (22) as shown in FIGS. 1 and 4 to prevent the door (5) from fluttering. Also, the door (5) improves the stability of the squareness of the side frames (2, 3) with respect to the upper frame (4). The stopper (22) is a substrate having a fitting protrusion (22B) fitted in a door-contact mounting groove (3A) of the side frame (3) on the door free edge (5B) side of the door frame (1) ( 22A) and a spacer (22C) inserted from the substrate (22A) and inserted between the door (5) and the side frame (3). Thus, in the door frame (1), the flatness of the side frames (2,3) and the squareness of the upper frame (4) and the side frames (2,3) are fixed as described above. ), But the door (5) is further prevented from fluttering during transportation and installation work by the stopper (22).

As described above, the door frame (1) is transported to the site with the door (5) attached, and is attached to the doorway of the building, after which the nails (19) are pulled out and the fixed splints (17) are removed. Remove the mounting bar (18), remove the nail (21), and remove the mounting bar (18) from the door stop mounting grooves (2A, 3A) of the side frames (2, 3) of the door frame (1). After removing the stopper (22), the door stop (23) is installed in the door stop mounting groove (2A, 3A) as shown in FIG.

The above-mentioned fixed splint (17) is made of wood, plywood, hardboard, hard plastic plate, iron plate, etc., but if the shape stability of the hard plastic plate, iron plate, etc. is large, the reinforcing beam (20) is not always necessary. Not necessary.

[0013]

[Effect of device]

 Therefore, according to the present invention, the mounting and dismounting of the fixed spar can be performed very easily and easily, and the efficiency of the work for mounting the door frame on the building is greatly improved.
