[First embodiment]
The composite board according to the first embodiment of the present invention will be described in detail. FIG. 1 is a partial sectional perspective view of a composite plate 1 according to the first embodiment of the present invention.

  As shown in FIG. 1, the composite plate 1 includes a plurality of connection units 3 in which a plurality of tubular bodies 31 are connected and fixed by a connection member 33 and a fastening member 34. At the same time, it is configured to be fixed to two plate members 2 and 2 that sandwich them from the length direction of the tubular body 31. At this time, the surface positions of the tubular bodies 31 are aligned in the same plane.

  FIG. 2 is a perspective view showing a tubular body 31 used for the composite plate 1 according to the first embodiment, and FIG. 3 is a view in which connecting units 3 constituting the composite plate 1 according to the first embodiment are arranged in parallel. FIG. 3A is a plan sectional view, and FIG.

  The tubular body 31 is configured by providing a pair of communication holes 312 in a cylindrical main body 311 whose both ends are open ends.

  The main body 311 is formed of a thermoplastic resin such as cylindrical vinyl chloride with both ends open.

  A pair of communication holes 312 is provided through the peripheral wall of the main body 311 in a direction horizontal to the plate 2. In the present embodiment, two are provided on the plane perpendicular to the length direction of the main body 311 and at positions facing each other across the center of the cross section of the plane.

  The communication hole 312 is formed on the side where the tensile stress is applied when the composite plate 1 is used. In the present embodiment, the communication hole 312 is formed of a plate material 2 different from the plate material 2 in a direction in which a load is applied when using the composite plate 1 used as a flooring material. It is formed to be biased toward the direction, that is, the lower end side of the main body 311.

  The communication hole 312 is formed to have an opening diameter larger than the diameter of the connecting member 33. Therefore, the connecting member 33 can be inserted into the communication hole 312.

  A predetermined number (11 in the example of FIG. 3) of tubular bodies 31 formed in this way are arranged in parallel with the communication holes 312 facing each other on a straight line perpendicular to the length direction. Then, the connecting member 33 is pierced through the communication hole 312 so as to penetrate the juxtaposed tubular bodies 31, and the end of the pierced connecting member 35 is fastened by the tightening member 34. Unit 3 is formed. At this time, the fastening by the connecting member 35 is performed so as to apply a pressing force to the tubular pair 31 included in the connecting unit 3.

  When the composite plate 1 is used in a state where a load is continuously applied from the one plate member 2 side, the tubular body 31 expands the diameter of the end portion at the end portion opposite to the load application direction. A tensile stress acting in the direction is generated.

  In the conventional composite plate, when the tensile stress is strong, the tubular body may be damaged. However, in the composite plate 1 according to the present embodiment, the communication hole 312 has a tensile stress when the composite plate 1 is used, that is, in the direction of the plate material 2 different from the plate material 2 in the direction in which a load is applied when the composite plate 1 is used. It is formed on the working side.

  The pressing force applied to the tubular body 31 due to the fastening of the connecting member 35 at the end of the tubular body 31 is biased toward the side on which the tensile stress acts when the composite plate 1 is used. Therefore, the pressing force acts in a direction to cancel the tensile stress, and the tubular body 31 can be effectively prevented from being damaged.

  In the present invention, the formation position of the communication hole is not limited to the aspect according to the present embodiment, and can be appropriately designed according to how the load is applied to the composite plate 1. For example, the above-described formation positions of the communication holes are effective when the direction in which the load is applied is clear, such as when the composite plate 1 is used as a flooring as in the present embodiment.

  On the other hand, when the composite plate 1 is used as a wall material, it is often unknown from which direction the load is applied. In such a case, by providing the communication hole 312 in the central portion of the tubular body 31 in the longitudinal direction, the tubular body 31 can be effectively prevented from being damaged when a load is applied from any direction. .

  The communication hole 312 is formed to have a diameter slightly larger than the cross-sectional diameter of the connection member 33 so that a slight gap is formed between the communication hole 312 and the connection member 33. The gap between the communication hole 312 and the connecting member 33 functions as a ventilation hole (not shown) that connects the inside and the outside of the tubular body 31.

  In the present embodiment, steel bars are used as the connecting members 33 and nuts are used as the fastening members 34. However, the present invention is not limited to this, and a metal cord or resin body may be used as the connecting member 33. In addition to using a locking member as the fastening member 34, the fastening member 34 may be fastened by welding with resin or caulking.

  A plurality of connection units 3 formed by the above-described method are arranged in parallel, and are sandwiched and welded between two plate members 2 to form the composite plate 1 according to the present invention. In the present embodiment, the plurality of connection units 3 includes a connection direction of the plurality of tubular bodies 31 included in the connection unit 3, and a contact direction between the tubular bodies 31 between the connection units 3 arranged in parallel. Are arranged so as to be orthogonal to each other. At this time, one tubular body 31 comes into contact with a maximum of four other tubular bodies 31.

  In the present embodiment, a steel plate is used as the plate material 2 that sandwiches the connecting unit 3. However, the present invention is not limited to this, and other materials such as a resin can be appropriately employed.

  The plate member 2 and the connecting unit 3 in the present embodiment are fixed by welding by heating and pressurization. When the plate member 2 is heated while the connecting unit 3 is in contact with and pressed against the plate member 2, the tubular body 31 made of resin is melted from the portion in contact with the plate member 2, and this molten portion is the plate member 2. It melts and adheres to the surface. Next, by cooling each member in this state, the plate member 2 and the tubular body 31 are fixed by welding, and the plate member 2 and the connecting unit 3 are fixed.

  Since the tubular body 31 is being fixed to the board | plate material 2 via the whole end surface at this time, it will be firmly fixed via a large area, and can improve the mechanical strength of the composite board 1. FIG. .

  In the present invention, the method of fixing the plate member 2 and the connecting unit 3 is not limited to welding, and may be performed using an adhesive.

By a simple method of passing the member 33, the tubular bodies 31 are grouped together as the connecting unit 3 having excellent handling properties.

  And the operation | work which arranges the some connection unit 3 in parallel can also be easily performed since the handleability of the connection unit 3 is favorable, and the assembly property of the composite board 1 can be improved. Further, a frame material is not required as in the prior art, the number of work processes is reduced, and productivity can be improved.

  Further, the fastening force by the connecting member 33 acts in a direction to cancel the tensile stress generated at the end portion of the tubular body 31 when a load is applied to the composite plate 1, thereby effectively preventing the tubular body 31 from being damaged. The strength of the composite plate 1 can be improved.

  Further, as described above, since the gap between the communication hole 312 and the connecting member 33 functions as a ventilation hole, the air in the thermally expanded tubular body 31 that has been generated in the welded portion at the time of welding is conventionally tubular. It is possible to effectively prevent the formation of small holes formed by trying to leak out from the melted portion of 31. And the fall of the fixed strength by the reduction of the welding area resulting from this small hole can be prevented, and the intensity | strength of the composite board 1 can be improved.

  In the composite plate 1 according to the first embodiment, the fixing between the tubular bodies 31 is performed only in one direction by the connecting member 33 used for forming the connecting unit 3, but the present invention is not limited thereto. Instead, the fixing of the tubular body 31 may be performed in other directions.

Is fixed. In the example illustrated in FIG. 4, a plurality of connection units 3 are fixed to each other by three second connection members 43. The fixing at this time is also performed such that a pressing force is applied to the tubular body 31 in a direction to cancel the above-described tensile stress.

  Thus, in addition to the connection member 33, the connection by the 2nd connection member 43 becomes easy, and positioning of the connection units 3 becomes easy, and the assembly property of the composite board 1 can further be improved.

  Moreover, the tolerance to the tensile stress mentioned above can further be improved, and the intensity | strength of the composite board 1 can further be improved by connecting several connection units 3 mutually.
