[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combination structure of a wooden double door used for an opening of a building such as a house.

[0002]

2. Description of the Related Art Conventionally, the construction of a wooden double door is as follows. One end of one door is cut into a shape corresponding to a ruler edge, and then a ruler edge is arranged. It was fixed with screws.

[0003] In order to harmonize the design, the material of the ruler edge is generally made of wood of the same or similar material as the door, and is manufactured so that the color, grain, texture, and the like are not unnatural. Was.

The fixing position of the ruler edge by a wood screw is fixed from the side of the door so that the head of the wood screw is not noticeable when the door is opened and closed.

[0005]

In a conventional wooden double door, the ruler edge is made of the same or similar wood as that of the door body, so that color, grain, etc. are used. Although there is an advantage that the appearance is in harmony with the door body, it has various problems caused by the material being wood.

[0006] In the case of a double door, the end of the corresponding door hits the mating portion when the door is opened and closed, and an impact is applied. This repetition may break the wooden ruler edge during use of the period.

Wood is susceptible to humidity in the air, elongates at high humidity, shrinks at low humidity, and has poor dimensional stability.

[0008] Cracks, warpage, and the like due to repeated expansion and contraction during use.
Twisting is likely to occur, and looseness of the wood screw may cause rattling at the joining portion.

Since the wood screw for fixing the ruler edge is externally attached from the side of the door, it is necessary to cut the wood screw into a shape corresponding to the mounting portion of the ruler edge, which requires time and skill.

On the other hand, when a metal material or engineering plastics is used for the ruler edge, various properties such as strength and dimensional stability are remarkably improved, but the design properties with the wooden door body cannot be harmonized due to the difference in the materials, The texture did not go along. SUMMARY OF THE INVENTION It is an object of the present invention to provide a double door double door structure having improved design and improved impact resistance of a wooden door, absorbing distortion due to dimensional change, and having excellent design.

[0011]

According to the present invention, in a joining portion of a wooden double door, a reinforcing member plate is fixed to a mounting portion with a ruler edge of one door by a plurality of wood screws,
Though we covered with a ruler edge of wood with a concave surface reinforcing plate is embedded, the reinforcing plate and the ruler edge wooden double doors, characterized in that it is fixed by a plurality of wood screw from stiffener plate side It is a combination structure.

In the combination structure of the wooden door of the present invention, a reinforcing plate which is to be buried and fixed to the edge of the wooden ruler is fixed to the end surface of the door with a plurality of wood screws. This reinforcing plate can be easily mounted by previously drilling a wood screw mounting hole.

The use of an extruded product having a shape corresponding to the door end, ie, the ruler edge mounting portion, as the reinforcing material plate enables standardization of specifications and improvement in dimensional accuracy.

As the material of the reinforcing material plate, extruded products such as aluminum and its alloys and engineering plastics, that is, polycarbonate resin, polyacetal resin, etc., are suitable, but not limited thereto. , Dimensional stability, workability, weight reduction, durability and the like.

The mounting of the reinforcing member plate to the door body can be matched with the shape of the door end, so that positioning can be performed accurately and quickly. Further, since it is not necessary to cut the door end, it can be easily mounted even at the construction site.

After the reinforcing plate is fixed to the door, a ruler edge whose concave portion is machined is mounted on the reinforcing plate so that the reinforcing plate is buried, and fixed with wood screws from the reinforcing plate side. .

Wood screws are used to fix the door and the reinforcing plate.
The use of countersunk screws is suitable for both the reinforcement plate and the ruler edge fixing.

The reinforcing material plate and the ruler edge can be fixed by a single wood screw, but can be more completely fixed by using an adhesive. As the adhesive, an epoxy resin-based adhesive, an adhesive sheet with double-sided adhesive and the like are suitable.

[0019] The reinforcing material plate is embedded and fixed on the ruler edge,
The integration improves the strength and dimensional stability, which are the drawbacks of wood.

The exposed surface of the reinforcing material plate, that is, the surface in contact with the opposite door is attached with a wood veneer, decorative sheet, cloth, or the like similar to the ruler edge, or is colored or painted to determine the difference in appearance from the wooden material. Can be reduced.

[0021]

[Function] Since the wooden ruler reinforced with the reinforcing material plate is fixed to the wooden door body, the strength of the mating portion is improved. Since the reinforcing material plate is fixed so as to be buried in the ruler edge, it is possible to prevent the ruler edge from expanding and contracting and to eliminate various disadvantages caused by dimensional changes.

The reinforcing plate is made of aluminum and its alloy,
Since an extruded product such as engineering plastics can be used, dimensional accuracy can be easily maintained.

Embodiments of the present invention will be described below with reference to the drawings. As a main material for forming an interior double door combination part made of birch, a reinforcing plate 1 shown in FIG. 1 and a wooden ruler edge shown in FIG. 2 are used.

An aluminum extruded product having a cross-sectional shape shown in FIG. The length of the reinforcing plate 1 is longer than the length of the door body. The reinforcing plate 1 is provided with through holes for wood screws for fixing the door body 3 and the ruler edge 2 in advance.

The fixing to the door main body 3 uses a 3.1 mm diameter, 25 mm long flat countersunk screw 4, and the fixing to the ruler edge 2 uses a 2.1 mm diameter, 13 mm long flat countersunk screw 5, respectively. Drill to fit a Phillips flatwood screw. The reinforcing plate 1 is arranged at one end of the double door as shown in FIG.

Next, a ruler edge 2 made of the same kind of birch material as the door body 3 having the shape shown in FIG. 2 is prepared. This ruler edge 2
Has the same paint finish as the door body 3. The ruler edge 2 is formed with a concave shape on the door surface side so that the reinforcing plate 1 is embedded.

In order to more completely fix the reinforcing member plate 1 and the ruler edge 2, the bonding is performed with an adhesive sheet 6 having a double-sided adhesive corresponding to the width and length of the reinforcing member plate 1, and then a Phillips flat head screw Fix at 5.

Next, a mohair 7 having a color similar to that of the wooden part is attached to the surface of the ruler edge 2 where the reinforcing material plate 1 is exposed, using a synthetic rubber adhesive.

Reinforcement plate 1 according to the length of the door body
The edge of the buried ruler is cut to complete the processing of the combined structure of this double door.

[0030]

[Effect] It is possible to form the reinforcing material plate into a shape such that the reinforcing material plate is in contact with the mounting portion with the door body.
In addition, since there is no need to cut the door body at the site for mounting the ruler edge, the mounting operation is simplified, and extremely accurate positioning can be performed.

Since the reinforcing material plate is embedded in the ruler edge and fixed with wood screws, strength such as impact resistance is improved, and expansion and contraction due to a change in humidity, which is a drawback of wood materials, is suppressed. This has the effect of preventing the mounting portion from becoming loose.

The countersunk screws for fixing the door body to the reinforcing plate are covered with a wooden ruler edge, and the reinforcing plate and the ruler edge are fixed from the reinforcing plate side.
When the door is closed, the reinforcing plate, the flathead screw head, and the like are completely hidden, do not appear on the surface, and do not deteriorate the design.
