Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a method for manufacturing a panel used in, for example, an industrial production house.

<Prior Art> In industrial production houses and the like, hollow panels are often used for walls and floors. It is advantageous to preliminarily form the hollow panel into a large size in a factory or the like and bring it to the construction site because the site construction is reduced. Therefore, in the past, hollow panels were
We standardize to a large size, and by doing this, we organize hollow panels by reducing the number of types.

As a conventional hollow panel manufacturing method, for example, a plurality of small-sized hollow panels are juxtaposed and side end surfaces of adjacent hollow panels are butted against each other and doweled together to form one hollow panel of a required size. Has been adopted.

<Problems to be Solved by the Invention> However, in the production of the hollow panel described above, when the side end faces of a plurality of hollow panels are dowel-joined, the side end faces to be joined are firmly joined to each other in order to firmly join the side end faces. The dowel must be press-fitted into the pre-formed dowel hole by strongly pressurizing it from a direction substantially orthogonal to the side end surface. Therefore, at the time of dowel coupling, the side end surface portion to be coupled is likely to float and the hollow panel is likely to be warped. If the hollow panel is further pressed in a warped state, the dowel itself may be broken or the dowel hole may be damaged, and as a result, the side end surfaces of the hollow panel may not be joined.

In order to prevent warping of the hollow panel at the time of dowel connection, a method of pressing the upper surface of the hollow panel with a plate material at the time of connection can be considered. However, it is necessary to prepare a plate material having a size substantially equal to or larger than the entire surface of the hollow panel to be manufactured, which requires a large amount of equipment.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a panel manufacturing method capable of preventing warping of a hollow panel at the time of dowel coupling, and capable of manufacturing with simple equipment.

<Means for Solving the Problems> A panel manufacturing method according to the present invention provides dowel holes on side end surfaces of a plurality of hollow panels in which plate members are attached to a rectangular frame,
In a panel manufacturing method for obtaining a single hollow panel by butt-joining the side end faces to each other to form a hollow panel, after arranging the plurality of hollow panels on a flat mounting table so as to obtain the hollow panel to be manufactured. , One of the side end faces facing outward and substantially parallel to the length direction of the side end faces to be joined with the dowels is pressed from a direction substantially orthogonal to the length direction of the side end faces to be joined with the dowels so as to face each other. A method of press-fitting dowels coated with an adhesive into the holes to join the side end faces to each other. When press-fitting the dowels into the dowel holes, at least 1 The long height regulating member of the book is arranged from the most distal hollow panel in the direction of pressurizing the side end face in a state substantially orthogonal to the length direction of the side end face to be doweled to the rearmost hollow panel. It is characterized by doing.

<Operation> In the panel manufacturing method according to the present invention, when the dowel is press-fitted into the dowel hole, the long height regulating member is provided in a state of being substantially orthogonal to the length direction of the side end face to be dowel-joined. In order to regulate the height of the upper surface of the hollow panel by arranging it from the most distal hollow panel in the pressing direction to the rearmost hollow panel,
It does not occur that the hollow side panel warps due to the side end face portion to be joined being lifted up by the pressure applied from a direction substantially orthogonal to the length direction of the side end face to be doweled.

Further, the lifting of the side end face portion to be doweled can be prevented only by disposing the long height regulating member without pressing the entire surface of the panel to be manufactured, so that at least one height regulating member is required. .

<Example> Hereinafter, an example of a panel manufacturing method according to the present invention will be described with reference to the drawings.

In this embodiment, as shown in FIG. 1, four standard-sized hollow panels 3 each having a plywood attached as a plate material 2 to a rectangular frame body 1 are joined together by dowel-bonding side end faces 4 of long sides. An example to which the present invention is applied when obtaining one large-sized hollow panel 5 for a wall (see FIG. 4) will be described.

As shown in FIGS. 1 and 2, dowel holes 7 are provided in the hollow panel 3 in advance in the frame member 6 of the side end surface 4 of the long side to be doweled. In addition, a dowel 8 to be pressed into this is prepared.

Then, first, four hollow panels 3 having dowel holes 7 are arranged on a flat mounting table 9 as shown in FIG. 3 so as to obtain a large-sized hollow panel 5 to be manufactured. Place it. However, at this point, the side end surfaces 4 are not brought into close contact with each other and are slightly spaced.

The mounting table 9 is composed of a rectangular flat table 9 in which the planned maximum size of the hollow panel 5 to be manufactured is set sufficiently, and the peripheral edge thereof is supported by the frame 10. . In order to facilitate the movement of the placed hollow panel 3 on the surface of the table 9,
A large number of free rolls are arranged so that they can appear and disappear. Further, the mounting table 9 has a height regulating mechanism 11 and a collective tightening mechanism.
12 and are provided.

The height regulating mechanism 11 is configured by mounting a pair of brackets 13 on opposite sides of the frame 10 and straddling a height regulating member 14 made of a long beam member between the pair of brackets 13. ing. The bracket 13 has a structure in which the mounting position can be changed and the height can be adjusted. The mounting table 9 is provided with two sets of such height restricting mechanisms 11, so that the height restricting member 14 is mounted on the mounting table 9.
Two are arranged.

The collective tightening mechanism 12 connects the side end faces 4 to be doweled,
It is tightened together from both end surfaces 4 that are substantially parallel to and dovetailed with the side end surfaces 4 to be doweled, and is composed of a pressing member 15 and a receiving member 16.

The pressing member 15 is a side end surface 4 that faces the outside and is joined to the dowel.
One of the both end surfaces 4 substantially parallel to is pressed from a direction substantially orthogonal to the side end surface 4 to be doweled. The pressing member 15 is the height regulating member in the frame 10.
Beams installed between two opposing sides that are substantially parallel to the length direction of 14
17 and two pressing screws 18 which are screwed in at right angles to the length direction of the beam 17 and are attached at intervals.
And a pressing piece 19 erected at its tip.
The beam 17 is installed between the two opposite sides of the frame 10 described above so that the mounting position can be changed.

Further, the receiving member 16 is a beam member projecting on the side of the frame 10 facing the beam 17, and the other one of both side end surfaces 4 facing the outside and substantially parallel to the side end surface 4 which is dowel-joined,
That is, it receives the most distal side end face 4 in the direction of pressure applied by the pressing member 15.

In this embodiment, as described above, after mounting the four standard-sized hollow panels 3 on the mounting table 9, the height regulating member is used.
14 is arranged in a state of being substantially orthogonal to the length direction of the side end surface 4 to be doweled and extending from the most distal hollow panel 3 to the rearmost hollow panel 4 in the direction of pressing by the pressing member 15.
At this time, the height regulating member 14 is arranged so as to lightly press the upper surface of the hollow panel 3. In this state, the dowels 8 coated with the adhesive are press-fitted into the facing dowel holes 7 of the side end faces 4 to be doweled, and the side end faces 4 are butted and joined together.

As the adhesive, a cyanoacrylate-based so-called instant adhesive, a quick-hardening type epoxy resin-based adhesive, a hot-melt type adhesive, etc. are properly used according to the number of dowel bonding points.
In this embodiment, an instant adhesive for woodworking is used. Since this adhesive has a fast curing time, the dowels are joined to the dowels 8 in the uncoated state on the dowels 8 with a distance of 1 to 2 cm between each side end face 4 here. .

Then, while the upper surface of the hollow panel 3 is lightly pressed by the height regulating member 14, the adhesive is quickly applied near the surface of the dowel 8, and immediately the two pressing screws 18 of the collective tightening mechanism 12 are pressed.
Is evenly rotated to press the pressing piece 19 against the side end surface 4 facing the outside and pressurize in a direction substantially orthogonal to the length direction of the side end surface 4 to completely press the dowel 8 into the dowel hole 7 and open it. The respective side end surfaces 4 are closed and doweled.

As a result, the respective side end faces 4 to be doweled are hardened and averaged and joined. In addition, the dowel 8 used in this case has a vertical groove in a part of the outer peripheral surface so that the adhesive is
It is good to make it easy to get around both ends of.

Further, the height regulation of the upper surface of the hollow panel 3 by the height regulation member 14 and the pressurization by the collective tightening mechanism 12 are held until the adhesive is cured, and after the adhesive is cured, it is taken out,
One large-sized hollow panel 5 shown in FIG. 4 is obtained.

As described above, in the panel manufacturing method of the present embodiment, the side end surface 4 for doweling the height regulating member 14 at the time of doweling.

It is possible to prevent the phenomenon that the hollow panel 3 is lifted and the hollow panel 3 is warped. Therefore, breakage of the dowel 8 itself and breakage of the dowel hole 7 can be prevented, and the side end surfaces 4 of the plurality of hollow panels 3 can be firmly dowel-joined. Further, the height regulating member 14 can also maintain the flatness of the entire surface of the obtained hollow panel 5.

In addition, since the floating of the side end surface 4 portion to be doweled can be prevented only by disposing the long height regulating member 14 without pressing the entire surface of the hollow panel 5 to be manufactured, the height regulating member 14 can be at least 1 You just need a book. Therefore,
Since the hollow panel 5 can be manufactured with a simple manufacturing facility, it is possible to suppress an increase in installation area and facility cost.

In addition, if both the height regulation mechanism and the collective tightening mechanism installed on the mounting table are provided in the two axial directions of the X axis and the Y axis,
It is possible to cope with a more complicated panel arrangement.
