Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work material such as a door frame and a window frame having a function of adjusting a wall thickness dimension.

[0002]

2. Description of the Related Art At present, in construction materials such as door frames and window frames, as shown in FIG. 1, a parent frame 101 and a child frame 102, in which a frame and a door stop are integrated, are slid to project the construction materials. The dimensions are adjusted to correspond to the wall thickness dimension.
However, when the size is set to be equal to or larger than the minimum size that can be adjusted by such a conventional work material with an adjusting function, the parent frame 101 and the child frame 10
Since a space is left between the two frames, a door stop, a step, or the like is attached to cover the space α between the two frames. Therefore, in the case of a door frame, there is no choice but to widen the width of the door-stop portion, and an unnatural step or a gap β is formed in the window frame, which causes a problem in appearance.

[0003]

In order to solve the above problems, the inventor of the present invention has proposed a structural material such as a door frame or a window frame composed of a surface material 2 and a core material 1 having a rectangular cross section. The surface material 2 is attached to the front surface of the core material 1 to a part of the back surface including the one-sided opening 1a, and the surface material 2 is bent to the back surface including the other opening 1b in an unattached state, and the core material 1 a plurality of V-grooves v1 for bending the surface material 2 when the core material 3 is included on the back surface of the surface material bent to the back surface
Invented a work material in which v2, v3, v4, v5 and v6 are formed.

[0004]

[Structure] 1 is a core material, and a bar material having a rectangular cross section is used. A surface material 2 is attached to a part of the back surface including a one-sided opening 1a on the front surface, and the other side includes a back surface including a opening 1b. Can be bent with the surface material not attached.

The core material includes solid wood, plywood, laminated veneer wood, medium fiber board, hard fiber board, particle board, wafer board, strand board, wood stick board,
A laminated base material, a wood-based base material such as LVL, a synthetic resin base material, an inorganic base material such as calcium silicate, ALC or the like may be used alone or in an arbitrary lamination.

On the other hand, the surface material 2 includes plywood, laminated veneer material, medium fiber board, hard fiber board, particle board, wafer board, strand board, wood stick board,
A decorative sheet-like material such as decorative paper, decorative resin-impregnated paper, decorative synthetic resin sheet or film, veneer, artificial veneer, etc. on the surface of laminated wood, LvL or other wood-based substrate, or optional coating on the decorative sheet-like object The applied one is attached.

The surface material 2 has V grooves v1, v2, on its back surface.
v3, v4, v5, v6 are formed, and include vinyl acetate resin, urethane resin, urea resin, and epoxy resin, including the front surface of the core material 1 and the one-sided opening 1a and reaching a part of the back surface. , V-groove v1, via an adhesive such as a melamine resin-based adhesive, or an adhesive obtained by optionally modifying them.
It is bent and attached from v2.

On the other hand, on the other side of the mouth piece 1b, the surface material 2 is not attached to the back surface of the core material 1 including the other side of the mouth piece 1b, and is bent and attached from the V grooves v3 and v5. A plurality of V grooves v4 and v6 for bending the surface material 2 when the additional core material 3 is included are formed on the back surface of the surface material that can be bent in the unattached state.

[0009] The plurality of V-grooves are adjusted to the wall thickness after temporarily removing the surface material bent in the unattached state, for example, when it is desired to widen the prospective dimension of the work material according to the wall thickness. After fixing another core material 3 having a size different from that of the core material 1 to the core material 1, the core material 1 is bent from one of the plurality of V grooves,
Provided so that adjustments can be made.

By engraving the V-grooves at the same pitch as the thickness of the core material, the combined separate core material 3 can be fixed to the core material 1 and bent. Can be adjusted. In addition, when the chamfering process is performed on the corners on the front surface side of the core material 1, one V-groove is sharper than the V-grooves other than the chamfered part so that the chamfered part can be bent. It is formed excessively.

[0011]

EXAMPLE FIG. 2 shows a case where the present work material is used as a door frame, and of course a door stop can be provided on the upper surface of the surface material. Generally, the estimated size of the door frame is 147-
It is set between 175 mm. Therefore, the width of the core material 1 is
When the surface material 2 is attached to both the mouths, the estimated size is determined to be the minimum 147 mm.

On the other hand, when the length of the surface material 2 is set to a maximum value at which the expected dimension can be adjusted, the surface material 2 including the core material 1 and the separate core material 3 fixedly attached to the back surface is also included. It must be large enough to be applied.

Specifically, when it is desired to set the estimated size to 147 mm, the surface material 2 which has been bent in the unbonded state may be directly bonded to the core material 1. In addition, the surplus surface material that should have been used when the expected size is 147 mm or more may be cut off, or an L-shaped cutting with sufficient space to attach the surface material to the back surface of the core material. If you make a notch and attach it to it, the back surface will be a flat surface.

175m, which is the maximum expected size that can be adjusted
When adjusting to m, the maximum expected size of adjustment (175 mm)
The separate core material 3 having a width obtained by subtracting the adjusted minimum expected dimension (147 mm) from the above is fixed to the core material 1, and the surface material 2 in the non-adhered state to the fixed core material 1 and the separate core material 3 is the V groove v4. Fold and stick at v6.

As described above, an adhesive is generally used to attach the unbonded surface material to the core material 1 and the separate core material 3, but it is previously bonded to the back surface of the unbonded surface material. Adhesive means such as a double-sided tape may be provided at the time of manufacture so that the work can be performed without using an agent or the like.

When adjusting the estimated size in the range between 147 mm and 175 mm, as in the case of setting 175 mm, another core material corresponding to the expected size to be adjusted can be prepared and attached. Good. V provided on the back of the surface material
When the groove is located on the surface side of the core material, a reinforcing means such as a filler may be provided in the v groove. Since a plurality of V-grooves are provided on the back surface of the surface material that has not been attached, the thickness being equal to the thickness of the core material, the surface material can be bent to any desired size to be adjusted, and various projections within the adjustment range are possible. The size can be adjusted.

[0017]

According to the present invention, when the wall thickness dimension is the minimum width within the range that the fabrication material can support, the surface material is attached only to the core material, and when it is the maximum width, another core material is attached to the core material. The surface material that has been fixed and not attached is attached and used. Further, when the wall thickness is within the range of the maximum width or more and the minimum width or more, another core material is cut into a length to be adjusted, fixed to the core material 1 and the V groove of the surface material 2 is bent, and then attached. To use.

[0018]

EFFECTS OF THE INVENTION In the fabrication material of the present invention, another core material is fixed to the core material 1 and the surface material is adhered, so that an unnatural step between the parent frame and the child frame is generated as in the conventional case. The present invention provides a door frame, a window frame, etc. that can be adjusted without impairing the appearance.
