DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to
The present invention relates to a structure for attaching a door frame attached to an opening.

[0002]

2. Description of the Related Art Conventionally, a door frame of a unit type house is generally transported to a building site in a form assembled in a factory as a door unit. The door frame is fixed directly to an opening formed in the wall with a nail or the like (see Japanese Patent Application Laid-Open No. 60-198884).

[0003]

In the above-described conventional method of mounting a door frame, the door unit may be subjected to an external force during transportation, and the frame may be distorted or a positional shift may occur between members. When attaching the door frame to the opening, it is necessary to correct the distortion of the door frame while adjusting the fixing position. This position adjustment is a troublesome operation requiring a lot of trouble.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a door frame mounting structure which can easily adjust a fixing position and correct distortion of a door frame when the door frame is mounted on an opening.

[0005]

In the present invention, in order to solve the above-mentioned problems, an angle member is vertically fixed to both longitudinal edges of the opening, and one of the upright pieces is provided with a required portion. A vertically long bolt insertion hole is provided, and the other upright piece of the angle material is provided with a horizontally long bolt insertion hole at a required position, and the angle material is vertically fixed to the outer surface of the vertical frame material on both sides of the door frame. In the upright piece of this angle material, a bolt insertion hole corresponding to the bolt insertion hole of the angle material at the opening is provided,
When attaching the door frame to the inside of the opening, butch the upstanding pieces of the angle material, insert the bolts into the matching bolt insertion holes, adjust the door frame up and down, left and right, correct the distortion, and then use the nut A door frame mounting structure that tightens and fixes both standing pieces is adopted.

[0006]

According to the present invention, first, an angle member is fixed to the longitudinal edges on both sides of the opening in the longitudinal direction with wood screws or the like. on the other hand,
Angle members are fixed in advance in the vertical direction on the outer surfaces of the vertical frame members on both sides of the door frame attached to the opening. Then, this door frame is fitted into the opening, the upright pieces of both the angle material of the door frame and the angle material of the edge of the opening are joined together, and the vertically or horizontally elongated bolt insertion hole of the angle material of the matched opening and the door frame After the bolt is inserted into the bolt insertion hole of the angle material, the vertical frame material of the door frame is adjusted up and down, front and rear, and the distortion of the door frame is corrected, and then both standing pieces are tightened and fixed with nuts.

[0007]

An embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view of an opening provided in a wall of a house, FIG.
Is a perspective view of one angle material for the opening, FIG. 3 is a perspective view of the other angle material for the opening, FIG. 4 is a perspective view of a vertical frame material of the door frame, and FIG. A perspective view, FIG. 6 is a cross-sectional plan view of a part of a joint between an opening and a vertical frame member of a door frame, and FIG. 7 is a part of a completed state of a joint part of an opening and a vertical frame member of a door frame. FIG. 8 is a cross-sectional plan view of the door portion when the door is completed.

In the figure, 1 is a wall of a house, and 2 is a rectangular opening for an entrance door 18 provided on the wall 1.
Angle members 3 and 4 are fixed in the vertical direction to the left and right vertical edges of the opening 2 with wood screws 16.

As shown in FIGS. 2 and 3, the angle members 3, 4 are attached to mounting pieces 5, 6 fixed to the edge of the opening 2, respectively.
And erecting pieces 7, 8 which stand at right angles from the edges of the mounting pieces 5, 6.

A plurality of screw holes 5a, 6a for inserting wood screws 16 are formed in the mounting pieces 5, 6.
A vertically long bolt insertion hole 7a is formed in a required portion of the upright piece 7 of one angle member 3, and a horizontally long bolt insertion hole 8a is formed in the upright piece 8 of the other angle member 4.

On the other hand, as shown in FIG. 4, an angle member 10 is fixed to the outside surfaces of the vertical frame members 9 on both sides with wood screws 17 in a vertical direction on a rectangular door frame previously assembled in a factory or the like. I have. As shown in FIG. 5, the angle member 10 has a mounting piece 11 fixed to the vertical frame member 9 and an upright piece 12 that stands upright from an edge of the mounting piece 11. The mounting piece 11 has a plurality of screw holes 11a through which the wood screws 17 are inserted. Bolt insertion holes 12a corresponding to the bolt insertion holes 7a and 8a of the angle members 3 and 4 of the opening 2 are formed in the standing piece 12. And
A nut 13 is welded to the back side of the bolt insertion hole 12a.

When the door frame is attached to the inside of the opening 2, the upright pieces 7 of the angle members 3, 4, 10 are used.
・ 12, 8 ・ 12 are abutted with each other, the bolts 14 are inserted into the matching bolt insertion holes 7a ・ 12a, 8a ・ 12a, and the left and right vertical frame members 9 are adjusted vertically and horizontally using the vertical and horizontal slots. Then, after correcting the distortion of the door frame, bolt 1
4. Tighten the upright pieces 7, 12, 8 and 12 with the nut 13 and fix them. At the end, the inner frame 15 is fixed between the vertical frame member 9 and the edge of the opening 2 to hide the angle members 3, 4, and 10.

It should be understood that the present invention is not limited to the above embodiment, and various design changes and the like made without departing from the gist of the present invention are also included in the scope of the present invention. . For example, the present invention can be applied to a part other than the entrance door, and the means for fixing the angle members 3, 4, 10 is not limited to a wood screw. Further, the nut 13 may be provided separately from the standing piece 12 without welding.

[0014]

As described above, according to the present invention, the angle material is fixed vertically to both longitudinal edges of the opening, and the upright piece of one of the angle materials is provided with a vertically elongated bolt insertion hole at the required position. On the other side of the upright piece of the angle material, a horizontally elongated bolt insertion hole is provided at the required position, while the angle material is fixed vertically on the outer surface of the vertical frame material on both sides of the door frame, and the upright of the angle material is raised. On one side, a bolt insertion hole corresponding to the bolt insertion hole of the angle material at the opening is provided, and when mounting the door frame inside the opening, the upstanding pieces of the angle material are butted against each other, and the bolt is inserted into the matching bolt insertion hole After adjusting the position of the door frame up and down, left and right to correct the distortion, the door frame mounting structure is used to tighten and fix both upstanding pieces with nuts. Frame straightening work An effect that can be easily performed.
