With respect to a manufacturing method for manufacturing a composite panel by pressing a plurality of building unit panels with a pressing machine, the structure thereof will be described with reference to FIGS. 1 to 3.

FIG. 1 shows a process of joining two adjacent building unit panels 10-1 and 10-2 when manufacturing a composite panel 1 using the building unit panel 10 of the present invention. It is a figure which shows the state before doing, (A) is a top view, (B) is a partial cross section figure of (A). Figure 2
2A and 2B are diagrams showing a state after joining in FIG. 1, FIG. 1A is a plan view, and FIG. 2B is a partial cross-sectional view of FIG. FIG.
FIG. 1 is a diagram showing a unit panel 100 for construction of the present invention,
(A) is a plan view, (B) is a front view, (C)
Is a right side view.

As shown in FIG. 1A, the pressing machines 30-1 and 30-2 are opposed to each other on a flat surface of a base provided with a transfer mechanism such as a transfer roller (not shown). A plurality of, for example, two building unit panels 10 are arranged in parallel between the pressing machines 30-1 and 30-2.

In addition, the pressing machines 30-1 and 30-2 facing each other
A stopper member (not shown) that can make the end surface of each building unit panel 10 flush with one another along a line B that is one end in the direction intersecting with It is located in.

As shown in FIGS. 1 to 3, the unit panel 10 for construction has a vertical core member 12 and a horizontal core member 1 assembled in a rectangular frame shape.
4, the reinforcing vertical core member 16 and the reinforcing horizontal core member 18 constitute a frame body, and the face member 20 is fixed to one surface thereof.

Further, as shown in FIG. 3C, a plurality of, for example, four holes 22 are formed in one of the vertical core members 12 constituting the unit panel 10 for construction. The holes 22 may be formed in both the vertical core members 12.

Further, a plurality of, for example, two building unit panels 10 are prepared. As shown in FIGS. 1 (A) and 1 (B), for example, one building unit panel 10-2 is provided with the hole 22. The dowel 24 is fitted and fixed in such a manner that one end thereof is projected.

Then, between the pressing machines 30-1 and 30-2,
In the building unit panel 10, the side surface of one building unit panel 10-2 to which the dowel 24 is attached and fixed, and the side surface having the hole 22 of the other building unit panel 10-1 face each other. Place it. Therefore, when the opposing side surfaces of the unit panels 10-1 and 10-2 for construction are joined together, as shown in FIGS. 2A and 2B, the dowels 24 are press-fitted into the holes 22. Becomes

The dowel 24 is a rod-shaped member having a function of connecting and supporting the two building unit panels 10-1 and 10-2, and the weight of the building unit panel 10 or other additional force. The material that does not cause shear compression deformation due to the above is, for example, resin, wood or the like.

Next, the location of the holes 22 or the dowels 24, which is a characteristic feature of the present invention, will be described.

As shown in FIGS. 3B and 3C, the hole 22 or the dowel 24 is located closer to the face material 20 than the center line C ₁ -C ₂ which divides the thickness of the building unit panel 10 into _two parts. A plurality of holes, for example four holes, are bored in a substantially straight line in the displaced region.

The reason for this is, as shown in FIG. 3 (B), for example, the bending rigidity of the vertical core member 12 on the center line C ₁ -C ₂ which divides the thickness into _two (area D), and the face member 20. When the bending rigidity at the position deviated to the side is compared with (E region), the bending rigidity of the vertical core member 12 is because the side material 20 side is reinforced by the surface material 20 in the case of single-sided attachment. Is a high position.

Therefore, the position is not limited to the illustrated position, and any position may be used as long as it is displaced to the face material side from the center line.
In addition, although a plurality of holes are provided in a line on a straight line, the present invention is not limited to this.
Two or three rows may be drilled.

As described above, as compared with the conventional case in which the dowel 24 or the hole 22 is formed on the center line C ₁ -C ₂ (FIG. 5), the dowel is located at a position displaced toward the face material 20 side having high bending rigidity. By forming the holes 24 or the holes 22, it is possible to prevent or reduce the conventional bending as shown in FIG.

In addition, since the bending can be prevented, the plurality of dowels 24 are smoothly and press-fitted into the plurality of holes 22 at the same time, and the opposite side surfaces are completely brought into close contact with each other, so that the building unit panel 10 is secured. The quality at the time of manufacturing a composite panel 1 by connecting a plurality of pieces improves.

The position where the hole 22 or the dowel 24 is disposed is, as shown in FIG. 3A, near the region where the horizontal core material 14 and the reinforcing horizontal core material 18 are joined to the vertical core material 12. Each is arranged.

The reason for this is, as shown in FIG. 3A, for example, the bending rigidity of a region of the vertical core member 12 which is not joined to the horizontal core member 14 or the reinforcing horizontal core member 18 (F region), and the horizontal core member. Material 14
Or, when comparing the bending rigidity of the region to which the reinforcing horizontal core member 18 is bonded (G region), the bonded region is reinforced by the horizontal core member 14 or the reinforcing horizontal core member 18,
This is because it becomes a region with high bending rigidity.

Therefore, the dowel 2 is provided at the position of the vertical core member 12 having the horizontal core member 14 or the reinforcing horizontal core member 18 and having high bending rigidity.
4 can be prevented to prevent the conventional vertical core member 12 from bending, and the quality when manufacturing the composite panel 1 by connecting a plurality of building unit panels 10 is improved.

On the other hand, as shown in FIG. 1 (A) and FIG. 2 (A), the projection 3 is formed on the end face 32 of the pressing machine 30 in the pressing direction.
A plurality of 4, for example, 4 are provided in a protruding manner.

The position of the protrusion 34 is set at the dowel 2 mentioned above.
It is arranged at a position facing the arrangement position of No. 4.

The reason is that the projection 34 presses the local position opposite to the position where the dowel 24 is provided, and the dowel 24 is not pressed at the low rigidity region where the dowel 24 is not provided. High rigidity region (vertical core 12
(A region where the horizontal core material 14 and the reinforcing horizontal core material 18 are joined)
This is because it is possible to prevent only the bending as in the conventional case by pressing only.

Moreover, by preventing the bending, the opposing side surfaces of the unit panels for construction 10-1 and 10-2 are in close contact with each other,
The quality of the composite panel is improved.

Incidentally, as shown in FIGS. 1 to 3, in this embodiment, the projections 34 provided on both ends of the pressing machine 30 are provided.
Is formed at least at both end edges thereof so as to directly press the region of the vertical core member to which the horizontal core member 14 is joined.

Next, the operation of this embodiment together with the method for manufacturing the composite panel 1 will be described with reference to FIGS.

The holes 22 are preliminarily formed in the vertical core members 12 of each of the plurality of building panels 10 in at least regions satisfying the above conditions.

Then, a desired number of composite unit panels 10-1, 10-2, for example, which are to be combined, are prepared, and each dowel 2 is placed in each hole 22 of one of the building unit panels 10-2.
4 is fitted and fixed with one end thereof protruding.

As shown in FIG. 1A, a desired number of sheets to be compounded, for example, 2 by a carrying mechanism such as a carrying roller (not shown) between the pressing machines 30-1 and 30-2 on the base (not shown). The building unit panels 10-1 and 10-2 are sequentially carried in.

At this time, the side surface of the building unit panel 10-2 on which one dowel 24 projects and is arranged, and the hole 22 on the other side.
Are arranged in a state of facing the side surface of the unit panel 10-1 for construction in which is arranged.

Further, at this time, one of the pressing machines 30-2 is
One short end face of each building unit panel 10-1 and 10-2 is flush with a line B where one end of one building unit panel 10-2 abuts and a stopper member (not shown) is formed. It is arranged in parallel in the state.

Next, the other building unit panel 10-1 is brought into contact with the other pressing machine 30-1, and the other pressing machine 30-1 is attached as shown by an arrow A in FIG. Move 1
The building unit panels 10-1 and 10-2 are interposed between the two pressers 30-1 and 30-2, and the building unit panels 10-1 and 10-2 are joined together, that is, composite. Is done.

At this time, as shown in FIG. 2, the plurality of dowels 24 of one building unit panel 10-2 are simultaneously pressed into the plurality of holes 22 of the other building unit panel 10-1. , The facing vertical core members 12 are completely in close contact with each other.

As described above, according to this embodiment, the vertical core 1
2 of the dowel 2 at a position deviated to the side of the face material 20 having high bending rigidity.
Since the construction unit panels 10 can be joined to each other by forming the holes 4 or the holes 22 without pressing a portion having a low bending rigidity, the conventional bending of the vertical core material can be prevented.

Moreover, since the bending can be prevented, the plurality of dowels 24 are smoothly press-fitted into the plurality of holes 22 at the same time, and the opposite side surfaces of the building unit panel are completely adhered to each other, and The quality when manufacturing a composite panel by connecting a plurality of unit panels for use is improved. Also, by forming a dowel or a hole at the position of a vertical core material with high bending rigidity having a horizontal core material or a reinforcing horizontal core material. The bending of the conventional vertical core material can be prevented, and the quality at the time of manufacturing a composite panel by connecting a plurality of building unit panels is improved.

Further, since the pressing machine is provided with the projection portion for pressing the local position opposite to the position where the dowel is arranged, without pressing the region having low rigidity where the dowel is not arranged, A plurality of dowels are simultaneously smoothed into a plurality of holes by pressing only a highly rigid region in which the dowels are arranged (for example, a horizontal core of a vertical core or a middle crosspiece to which a reinforcing horizontal core is joined). Since it is press-fitted into the composite panel, it is possible to prevent the deflection, and the opposite side surfaces are brought into close contact with each other to improve the quality of the composite panel.

The present invention is not limited to the above embodiments, but various modifications can be made within the scope of the invention. For example, the arrangement positions of the dowels 24 or the holes 22 are shown in FIG.
Not limited to the example as in (C), it is a position deviated to the face material 20 side with respect to the center line C ₁ -C ₂ , or the horizontal core member 14 or the auxiliary horizontal core shown in FIG. 3 (A). One of the positions near the region where the material 18 and the vertical core material 12 are joined may be adopted. However, in this case, the deflection is reduced by either one, but the deflection is minimized by adopting both.

Further, the protrusion 34 is formed by the pressing machine 30-1.3.
The configuration may be such that it is formed in only one of 0-2.

Further, although the shape of the hole 22 is circular in this embodiment, it may be another shape, for example. Therefore, the shape of the cross section of the dowel 24 may be a shape deformed corresponding to the hole 22. Moreover, the tip of the dowel may be tapered.

Further, in this embodiment, the number of the reinforcing horizontal core members is two, but as the number of the reinforcing horizontal core members increases, the holes,
The number of dowels and protrusions may be correspondingly increased in the vicinity of the region. In that case, it may be provided in correspondence with each reinforcing horizontal core material, but the number does not have to correspond.

The building unit panels to which the present invention is applied include flooring and roofing panels which are single-sided materials, and building unit panels where the facing material attached to the frame is a finishing material, for example, flooring. It may be a floor panel or the like, or a double-sided panel such as a wall panel.

[0071]

According to the first aspect of the present invention, it is possible to reduce the deflection of the side face as in the conventional case by forming a hole at a position deviated in a face material having high bending rigidity.

Moreover, since the above-mentioned bending is reduced,
A plurality of dowels are smoothly press-fitted into a plurality of holes at the same time, and when multiple sheets are connected, the opposite side faces are completely in close contact with each other, and the quality when connecting multiple building unit panels to produce a composite panel Is improved.

According to the second aspect of the present invention, at the position of the vertical core material having a high bending rigidity with the horizontal core material or the reinforcing horizontal core material,
By forming holes for fitting dowels, it is possible to reduce the bending of the conventional vertical core material, and improve the quality when manufacturing a composite panel by connecting a plurality of building unit panels.

According to the invention of claim 3, claim 1
Alternatively, as in the second aspect of the invention, the opposite side faces are completely in close contact with each other, and the quality of the composite panel is improved.

According to the invention described in claim 4, the pressing machine presses the local position facing the position where the dowel is arranged.

Therefore, it is possible to prevent bending by pressing only the highly rigid region where the dowel is provided without pressing the weakly rigid region where the dowel is not provided, and the opposing side surfaces are in close contact with each other to form a composite. Improves panel quality.
