Even when the narrow plates 20 are pressed by the pressing surfaces 22, 22 of the second frame members 18a, 18b, the narrow plates 20 do not jump up, and the narrow plates 20a at the side ends of the stacked narrow plates 20 are smoothly tightened from the horizontal direction. Thus, the tightened state of the narrow plate 20 can be stably maintained. As the frame member, a material having a suitably high strength or a thick frame is selected in accordance with the required tightening force.

The first and second frame members 18a, 18a, 18a
8b may be any configuration as long as the screw shaft and the receiving member penetrate these in an intersecting manner. Therefore, only the outer surface side of the frame, that is, the rectangular pipe 26, the first and second flange plates 32 and 33 are joined together. It may be configured to be connected in a square frame shape by a plate. In this case, instead of the H-shaped steel, the rectangular pipe 26, the first and second flange plates 32, 3
The member 3 may be made of a pipe material such as a plate material, a bar material, a square tube, a round tube, or the like, and the pressing plate 30 may be omitted, and the back surface thereof may be directly pressed toward the space 16. However,
Preferably, it is necessary to apply the pressing force in the direction toward the space 16 to the mounting support of the receiving member 44 and to apply a pressing force in the direction toward the interval 16 to both the frame members 18a and 18b. It is preferable that the entire frame in the pressing direction width corresponding to the H-shaped steel reinforcing plate 28 be a rigid body.

Next, the operation of the plate joining apparatus according to the embodiment of the present invention will be described. A large number of narrow boards 20 are formed by sawing off offcuts and thinned wood generated in a sawmill. Therefore,
As shown in FIG. 7, the first and second frame members 18a and 18b are arranged on the upper surfaces of the left and right bases 14 and 14 so as to face each other.
The plurality of receiving members 44 are passed through the long holes 46, 46 at the lower end sides of the frame members, and are mounted and supported with both ends protruding. And the first and second
At the interval 16 between the frame members 18a, 18b, the narrow plate 20 having an adhesive applied to the side end surfaces on the upper surfaces of the plurality of receiving members 44 is provided with the first and second frame members 18a, 18b.
The two frame members are arranged in parallel so as to be parallel to 18b, that is, they are mounted along the longitudinal direction of both frame members and are joined and arranged in the width direction.

A plurality of bars 60 are placed on the upper surface of the first-stage narrow plate 20 arranged in the joining direction in the width direction W of the narrow plate 20, and an adhesive is similarly applied to the upper surfaces of these narrow bars 20 on the side end surfaces. The narrow plate 20 on the second stage is placed with the coated narrow plate 20

As described above, after the small width plates 20 are joined and arranged in a plurality of stages and stacked, as shown in FIG. 7, approximately four screw shafts 40 from which one end side nut member 58 is loosened and removed are attached to the first shaft. At a position near the center of the interval 16 between the second frame members and a position near both side ends, the elongated hole 42 is made to penetrate from the outer surface side of one of the first frame members 18a and to the elongated hole 42 of the other second frame member 18b. The screw shaft 40 is passed through the first and second frame members 18a, 18
b so that the thread groove portion on the tip side protrudes toward the outer surface side. The nut members 58 are screwed into the respective protruding ends of the screw shafts 40 on the second frame member 18b side.

As shown in FIG. 8, a narrow plate 20 is similarly joined and arranged on the upper surface of a screw shaft 40 having both ends penetrated by the first and second frame members 18a and 18b. Are piled up to the same height as the upper end height of the first and second frame members 18a, 18b with the crosspiece 60 interposed therebetween. That is, in the embodiment, the screw shaft 40 itself functions as a receiving member. As shown in FIGS. 8, 9 and 10, after the narrow plates 20 are stacked in a plurality of stages on the upper surface of each screw shaft 40, the first and second frame members 18a and 18b are arranged from the uppermost narrow plate 20 side. The top cover 62 is attached to the top of the device. That is, the plurality of holding frames 64 intersect with the narrow plate 20 so that the first and second frame members 18a, 18a,
8b, and crossing holding frames 66, 66 are mounted so as to cross the upper surfaces of both ends of each holding frame 64. First,
The hooks 74, 74 of the fastening portions 68, 68 installed on the outer surface side of the second frame members 18a, 18b
6 and 66, and the nut 76 of the long bolt 72
, And lightly contact each holding frame 64 with each narrow plate 20.

In this state, the nut member 50 screwed to one end side of each screw shaft 40 is closed to move the first and second frame members 18a, 18b to face each other, and to press their elastic pressing surfaces 78, 78. The side surfaces of the narrow plates 20a, 20a on the side end portions of the narrow plates 20 being stacked are pressed substantially horizontally, and this pressed state is maintained for a required time. After the adhesive on the joint surface of each narrow plate 20 is solidified in about two hours, the fastening portion 68 of the upper cover 62 is loosened to remove the holding frame 64 and the cross holding frame 66, and the upper surface of the screw shaft 40 is removed. The product 82 is taken out. Further, a nut member 50 at one end of each screw shaft 40 is provided.
And remove the screw shafts 40 from the first and second frame members 18a and 18b, take out the products 82 stacked on the upper surface side of the receiving member 44, and end the width joining operation. After that, the next width joining operation is continuously performed while the next small width plate is joined and arranged on the receiving member 44 within the interval 16.

As described above, the nut members of the respective screw shafts penetrated by the first and second frame members are manually rotated, for example, and a plurality of nut members are arranged and supported within the interval between the first and second frame members. By pressing and joining the narrow plates almost horizontally,
A wide board such as a field board excellent in strength, corrosion resistance, durability and the like can be easily manufactured by performing width joining of a small width board or the like obtained by cutting wood. In addition, it can be used effectively while processing narrow boards with scrap wood generated in sawmills or thinned wood discarded in forests, and there is no need to use electric power, and it is inexpensive even by manual work alone. The width of the plate material can be connected. In addition, since the first and second frame members have a simple configuration in which the screw shaft and the receiving member are inserted in a cross shape, the equipment cost of the device itself is low. The fastening and removal of the nut member may be performed by providing an electric wrench mechanism (not shown).
