Abstract

PURPOSE: To provide a panel that is lightweight and is enhanced in handling and workability by filling a polyurethane foaming material into the inside space of a flat-board-shaped synthetic resin body that has been surrounded by thin- thickness wall parts. CONSTITUTION: A panel 1 is made up of a flat-board-shaped synthetic resin body 3 that has been surrounded by thin-thickness wall parts 2, a fixing frame 4 that has been fitted around the circumference of the body 3, and a polyurethane foaming body P that is filled into the inside space S of the body 3. In the nearly central part of vertical wall part 2a, opening parts 6 are provided respectively, and a reinforcing member 14 is inserted into the opening parts 6 so as to keep a clearance between the opening parts 6 and the reinforcing member for securing the flow of urethane to be filled. Then, polyurethane is poured into the inside space S in such a state that the reinforcing member 14 has been floated inside the respective opening parts 6, and polyurethane is foamed to expand the body 3 itself from the inside, so that the vertical fixing frame 4a and the horizontal fixing frame 4b that have been fitted to the vertical wall part 2a and the horizontal wall part 2b are fixed to the body 3.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The panel of the present invention and the door using the same will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway perspective view for explaining an embodiment of a panel of the present invention, FIG. 2 is an enlarged view of a corner portion of a main body and a fixing frame in FIG. 1, and FIG. 3 is a perspective view of a cap in FIG. 4 is a cross-sectional view showing fixing of the vertical wall portion and the vertical fixing frame in FIG. 1, and FIG. 5 is a cross-sectional view showing fixing of the horizontal wall portion and the horizontal fixing frame in FIG.

As shown in FIGS. 1 and 2, the panel 1
Is a flat plate-shaped main body 3 surrounded by a thin wall portion 2,
The main body 3 is composed of a fixed frame 4 fitted in four sides and a polyurethane foam P filled in an internal space S of the main body 3.

Of the wall portions 2 of the main body 3, the vertical wall portion 2a has an opening portion 6 formed at substantially the center thereof. In addition, the vertical wall portion 2a, the horizontal wall portion 2b, and the central wall portion 2
A longitudinal guide groove 9 and a lateral guide groove 10 are formed along the entire length between c and c. The vertical guide protrusions 11 and the horizontal guide protrusions 12 formed by the guide grooves 9 and 10 are formed slightly lower than the height of the center wall portion 2c. A reinforcing material 14 is inserted from one opening 6 to the other opening 6 between the vertical wall portions 2a. The reinforcing material 14 is inserted into the opening 6 so as to maintain a gap between the reinforcing material 14 and the opening 6 in order to secure the flow of urethane to be filled (FIG. 1B).
reference). As the reinforcing material 14, for example, a square pipe having a V-shaped cross section can be used. The reinforcing member 14 reinforces the main body 3 and prevents the main body 3 from warping. Further, in the opening 6, as shown in FIG.
A cap 15 having a tapered projection 15a is fitted to the inner walls facing each other. As a material of the main body 3, a synthetic resin such as AES resin, AS resin, ABS resin, or polyethylene can be used. As a method of molding the main body 3, a blow molding method, a sheet molding compound (SMC) molding method, a compression molding method, or the like can be used.

Of the fixed frame 4, the vertical fixed frame 4a has a T-shaped groove 17 in the upper and lower stages as shown in FIGS. 2 and 4 (a).
a and 17b are formed to face each other. Vertical fixed frame 4
As shown in FIG. 2, a notch 19 is formed at the tip of the lower stage of a so that the end of the horizontal fixing frame 4b fits therein. The horizontal fixing frame 4b, as shown in FIG. 2 and FIG.
A C-ring-shaped pipe 20 is integrally formed in the upper rectangular groove 19a, and a T-shaped groove 19b is formed in the lower step. The vertical fixed frame 4a and the horizontal fixed frame 4b guide the T-shaped grooves 17b and 19b in the vertical guide groove 9 of the vertical wall portion 2a and the horizontal guide groove 10 of the horizontal wall portion 2b, respectively.
It is slid and fitted. The material of the fixed frame 4 is aluminum alloy, ABS resin, AES.
A synthetic resin such as a resin can be used.

The polyurethane foam P is made of rigid or semi-rigid polyurethane, and is obtained, for example, by adding a foaming agent and a silicone-based surfactant together with a catalyst and other additives to a polyol component and mixing with an isocyanate at the time of molding. It can be used. The expansion ratio is not particularly limited in the present invention,
About 15 to 27 times is a standard. The cap 15
The polyurethane is poured into the internal space S in a state where the reinforcing material 14 is floated in each opening 6 by the protrusions 15 a. After that, a reaction raw material for foaming is injected. Thereby, the polyurethane is foamed and the main body 3 itself is expanded from the inside, so that the vertical fixing frame 1 fitted to the vertical wall portion 2a and the horizontal wall portion 2b.
4 and the horizontal fixing frame 4b are fixed to the main body 3.

Next, the fixing of the wall portion 2 and the fixed frame 4 will be further described with reference to FIGS. 4 and 5.

First, as shown in FIG. 4 (a), the vertical wall portion 2a of the wall portion 2 and the vertical fixed frame 4a of the fixed frame 4 are fixed to each other as shown in FIG. 4 (b) when the polyurethane foams as described above. As shown, since the vertical wall portion 2a5 is thin, the vertical wall portion 2a5 is expanded outward by expansion, and the lower T-shaped groove 17b of the vertical fixing frame 4a is expanded.
It is done by filling the inside.

Next, as shown in FIG. 5 (a), the horizontal wall portion 2b of the wall portion 2 and the horizontal fixed frame 4b of the fixed frame 4 are fixed to each other when the polyurethane foams, as shown in FIG. 5 (b). Since the lateral wall portion 2b is thin, the lateral wall portion 2b is expanded and expanded outwardly to fill the lower T-shaped groove 19b of the lateral fixing frame 4b.

After the fixing frame 4 is fixed to the wall portion 2 in this way, as shown in FIG. 2, from the through hole 21 formed at the tip of the upper stage of the vertical fixing frame 4a to the pipe 20, for example, both end tips. Insert a bar (not shown) on which screws are engraved,
If tightened from both ends with nuts (not shown), it can be fixed more firmly.

In the panel of the present invention, the surface of the main body is coated in order to give it a good appearance and weather resistance. As the paint used for this painting, the material of the main body,
It can be appropriately selected according to the place where the panel is used.For example, oil paint such as oil paint,
A synthetic resin paint such as a phenol resin or an epoxy resin can be used, and the mixing ratio thereof can be appropriately selected. The coating conditions, for example, the thickness of the coating film is usually about 100 to 500 μm, but depending on the place of use, a thick film of about several mm can be used
As the coating method, brush coating, spray coating, roll coating, etc. can be used.

Next, an example of using the panel of the present invention will be described.

The panel of the present invention can be suitably used especially for gates, doors, partitions, etc. of houses and the like.

For example, when it is used for a gate, FIG.
As shown in FIG. 5, a long hole 22 for attaching a handle (not shown) such as a knob and a hole 23 for attaching a key (not shown) are formed in the side portion of the main body 3. A side edge member for preventing the cap 15 from coming off due to foaming of polyurethane is attached to the T-shaped groove 17a formed in the upper stage of the vertical fixing frame 4a.

[0024]

As described above, according to the panel of the present invention, since the polyurethane foam is filled in the internal space formed in the main body made of synthetic resin, the panel is strong and lightweight. Therefore, it is very easy to handle when constructing a gate or the like in a building such as a house.
