DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing method and a fixing structure between a door frame and a base material.

[0002]

2. Description of the Related Art As shown in FIGS. 6 and 7, a door frame 1 for mounting a door so that the door can be opened and closed is fixed to a base material 2 at an opening by a fixing tool such as a wood screw 9 or a nail. As the base material 2, studs or pillars 22, 23, lintels 24,
There is a paddy tree 25 and the like. In the fixing, for example, as shown in FIG.
A sheet pile 81 as shown in FIG.

[0003] The sheet piles 81 are separated from each other by a gap 80 from opposite directions.
Is inserted inside. The gap 80 between the door frame 1 and the shaving 25 occurs because the size of the base material 2 is designed to be slightly larger in advance so as to be adaptable to door frames 1 of various sizes. . The gap 80
Occurs between 0.5 and 1.5 cm depending on the size of the door frame 1.

[0004]

However, the conventional door frame fixing method and fixing structure have the following problems. That is,
As shown in FIGS. 7 and 9, on the surface of the door frame 1 fixed as described above, the head 91 of the fixing wood screw 9 or the head of the fixing tool such as the head of a nail is exposed, which impairs the beauty. Therefore,
It is necessary to cover the head of this fixture with a paint of the same color as the door frame 1 after fixing the door frame 1.

Further, as shown in FIG. 10, when the door frame 1 is fixed to a base material such as a paddle 25 using a fixing tool such as a wood screw 9, if the wood screw 9 is pressed down too much, the door frame 1 is bent. Is generated. Therefore, it is necessary to be careful when pressing down the fixing tool such as the wood screw 9. Therefore, work by a professional such as a carpenter is required. As described above, the conventional fixing method and the fixing structure of the door frame require complicated work for completing the door frame, which increases the cost.

The present invention has been made in view of the above-mentioned conventional problems, and it is easy to attach the door frame to the base material, and it is possible to securely fix the door frame to the base material, and to reduce the cost of the door. An object of the present invention is to provide a frame fixing method and a fixing structure.

[0007]

According to the present invention, when a door frame is fixed to a base material at an opening, a gap between the door frame and the base material is provided.
A spacer made of an elastic foam is interposed at intervals, and then a foaming adhesive is applied to an upper portion of the spacer so that the door frame and the base material are connected directly or through the spacer.
And fixing the foaming property with an adhesive.

An elastic foam is used as the spacer.
You. As such an elastic foam, there is a plastic porous body such as polyurethane foam and styrene foam. When an elastic foam is used as the spacer, the spacer has elasticity, so that the space between the door frame and the base material is
The spacer can be inserted without difficulty. for that reason,
The gap between the door frame and the base material can be maintained at the dimension at the time of design, and the door frame does not bend.

[0009] In addition, the adhesive Ru using a foaming adhesive. As such an expandable adhesive, there is an expandable polyurethane adhesive. When a foaming adhesive is used, after the spacer is inserted between the door frame and the base material, the foaming adhesive is applied to the upper portion of the spacer, and foaming occurs immediately and solidifies. Therefore, the door frame and the base material can be fixed in a short time. Therefore, the fixing work of the door frame can be completed in a short time. The fixing by the above-mentioned adhesive is carried out by directly fixing the door frame and the base material or between the both via the spacer.

[0010] Examples of the base material include studs and pillars located on the left and right sides of the door frame, oysters located between the door frames and pillars, and "magpies" located above the door frame. As a method of interposing the spacer between the door frame and the base material, there is a method in which a door frame that has been framed in advance is positioned between the base materials and then the spacer is inserted into a gap between the two. Further, there is a method in which a spacer is fixed to one of a door frame and a base material with an adhesive or the like in advance.

Next, as a fixing structure of the door frame, the gap between the door frame and the base material of the opening is elastically spaced apart from each other.
A spacer made of foam is interposed between the door frame and the base material directly or through the spacer.
There is a door frame fixing structure characterized by being fixed by a foaming adhesive .

The above spacers, adhesives and the like are the same as those described for the fixing method. The spacers are arranged at appropriate intervals, for example, 30 to 45 cm. If it exceeds 45 cm, the spacing between the spacers is too large, and the fixing between the door frame and the base material may be insufficient. On the other hand, if it is less than 30 cm, the number of spacers increases more than necessary, and the number of work steps increases.

The application of the adhesive is performed, for example, between the upper surface of the spacer and the door frame and between the upper surface of the spacer and the base material. Since the contact surfaces of the spacer, the door frame, and the base material are in close contact with each other, it is unlikely that an adhesive will enter between them. Generally, the spacers are 2 to 5c.
Since the width is m, by applying an adhesive to the surface of the spacer, the adhesive flows between the periphery of the spacer and the door frame, and between the periphery of the spacer and the base material. Therefore, the door frame and the base material are fixed to each other with an adhesive or via a spacer.

[0014]

In the door frame fixing method of the present invention, the door frame and the base material are fixed with an adhesive. Therefore, as shown in the above-mentioned conventional example, the head of the fixing tool such as a wood screw or a nail is not exposed on the surface of the door frame.
Therefore, the beauty of the surface of the door frame is not impaired. Also, there is no need to apply paint to hide the head of the fixture, and the work of mounting the door frame is easy.

Further, since the door frame and the base material are fixed with the spacer interposed therebetween, the gap between the two is maintained as it is, the mounting and fixing between the both are secure, and the mounting operation is easy. And the cost is low. Also, in the door frame fixing structure, the same operation and effect as described above can be obtained.

Therefore, according to the present invention, the work of attaching the door frame to the base material is easy, and the door frame can be securely fixed to the base material. An anchoring structure can be provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A door frame fixing method and a fixing structure according to an embodiment of the present invention will be described with reference to FIGS. In this example, when fixing the door frame 1 to the base material 2 in the opening, first, the gap 20 between the door frame 1 and the base material 2 is set.
The spacer 3 is interposed at an interval. Then, an adhesive 4 is applied between them to fix them.

That is, when fixing the door frame 1 and the base material 2, first, as shown in FIGS. 2 and 3, studs or pillars 23, lintels 24, and pillars 2 are previously provided as base materials for openings.
The door frame 1 is positioned in the frame of the base material 2 made of the stake 25 fixed to the door frame 2. At this time, a gap 20 is formed between the base material 2 and the door frame 1. Therefore, as shown in FIG. 4, the spacers 3 obtained by cutting the polyurethane foam into long rectangular pieces are inserted into the gaps 20 at appropriate intervals.

Next, an adhesive injector is inserted between the gaps 20 to apply a foaming polyurethane adhesive around the spacer 3. After a short time, the adhesive 4 foams as shown in FIGS.
Solidify. Thereby, the door frame 1 and the base material 2 are fixed to each other by the adhesive 4 or the door frame 1 and the base material 2 are fixed to each other via the spacer 3 fixed to both of them by the adhesive.

It is not necessary to apply the adhesive 4 to the entire periphery of the spacer 3. For example, when the adhesive 4 is applied in the vertical gap 20 (right side in FIG. 5), the upper portion of the spacer 3 and the door frame are 1, it may be only applied between the upper part of the spacer 3 and the shavings 25. By such an application, the adhesive 4 foams and solidifies while flowing down the adjacent portion (right-angled portion) of the spacer 3 and the door frame 1 and the spacer 3 and the shaving 25, and the space therebetween is fixed.

Next, the operation and effect of this embodiment will be described. In this embodiment, as described above, a spacer is inserted into the gap 20 between the door frame 1 and the base material 2, interposed therebetween, and an adhesive is applied to fix the door frame 1 and the base material 2. Therefore, on the surface of the door frame 1, as shown in the conventional example,
The heads of fixing devices such as wood screws and nails are not exposed. Therefore, the beauty of the surface of the door frame 1 is not impaired. Further, there is no need to apply paint for hiding the head of the fixture, and the work of mounting the door frame 1 is easy.

Further, since the door frame 1 and the base material 2 are fixed by an adhesive with the spacer 3 inserted in the gap 20 between them, the gap between them is maintained as it is, and the attachment and fixation between the two is ensured. In addition, the mounting work is easy and the cost is low.

In this embodiment, since the polyurethane foam is used as the spacer 3, the spacer has elasticity. Therefore, the spacer 3 can be easily inserted between the gaps 20, and the gap between the door frame 1 and the base material 2 can be maintained at the designed size.
The door frame does not bend. In this example,
Since the foamable polyurethane adhesive is used as the adhesive, the spacer can be fixed in a short time.
