Abstract

PROBLEM TO BE SOLVED: To provide a structural material having very easily adjustable dimension.SOLUTION: The structural material comprises: a material body 3 formed by laminating block materials 1 in a close contact condition and having a flat face 2 of a predetermined width, continued in the laminating direction; and a connection body 4 formed to be cuttable with a cutter and bonded to the flat face 2 to connect each of the block materials 1. By cutting the connection body 4 with the cutter along an interface between the block materials 1, 1, an appropriate number of the block materials 1 are separated from the material body 3, and the dimension in the block material 1 laminating direction can be adjusted. The connection body 4 can be cut with the cutter, that is, has suitable tensile strength, and the interface between the block materials 1, 1 has a predetermined sectional area, and therefore, the connection body 4 does not easily rupture when a vertical load F acts as a tensile directional force T. Furthermore, since the respective block materials 1 are in a condition of close contact with one another, a shearing force acting between the block materials 1 of the connection body 4 can be restricted extremely small.

Description

  The present invention relates to a structural material.

  Conventionally, as a structural material capable of facilitating dimensional adjustment, a shelf set member described in Patent Document 1 is known. This shelf board set member is formed by fixing a board material on the upper and lower surfaces of a shelf frame body formed by forming a pair of a vertical frame material and a horizontal frame material into a square frame, and filling a hollow core with a paper core material. And the auxiliary vertical frame member having substantially the same size as the vertical frame member. The shelf plate is cut to a desired dimension in a direction orthogonal to the longitudinal direction of the horizontal frame member, and the auxiliary vertical frame member, which has been previously coated with an adhesive, is pushed into the hollow portion from the cut surface. Then, the auxiliary vertical frame material can be fixed at a position where the paper core material is compressed to close the hollow portion.

  When cutting the above-mentioned shelf board, it is only a matter of cutting the horizontal frame material and the board material, which is a wooden material but having a small cross-sectional area in the cutting direction, and the paper core material, that is, paper. It seems to be.

  However, the above-described conventional example has a drawback in that it takes time and effort to reinforce the cutting site with the auxiliary vertical frame member in addition to the cutting operation when adjusting the dimensions.

  In this respect, the above-described work such as reinforcement is not necessary if it is not a flash structure as described above but is a simple solid material, for example, but in this case, a great deal of labor is required for the cutting work.

  The present invention has been made to eliminate the above-described drawbacks, and an object of the present invention is to provide a structural material with extremely simple dimensional adjustment.

According to the present invention, the object is
A material body 3 that is formed by laminating block materials 1 in close contact, and has a flat surface 2 having a predetermined width continuous in the laminating direction;
This is achieved by providing a structural material that is formed so as to be cut by a cutter and has a connecting body 4 that is bonded to the flat surface 2 and connects the block members 1.

  According to the present invention, the structural material adheres the connecting body 4 to the material body 3 in which the block materials 1 are stacked in close contact, and connects the block materials 1 by the connecting body 4. The connecting body 4 is formed so as to be cut by a cutter. If the connecting body 4 is cut by a cutter in accordance with the boundary between the block materials 1 and 1, an appropriate number of block materials 1 are separated from the material body 3 and blocked. The dimension of the material 1 stacking direction can be adjusted.

  Adhesion of the connecting body 4 to the material body 3 is performed on the flat surface 2 having a predetermined width that is continuous in the stacking direction of the material body 3, whereby the connecting body that can be cut with a cutter between the block members 1 and 1. 4 is arrange | positioned so that it may straddle with predetermined width, ie, a predetermined cross-sectional area, and intensity | strength is ensured. That is, for example, as shown in FIG. 3A, when a cantilever model is configured by attaching the coupling body 4 to the upper surface serving as a load acting surface of the material body 3, a vertical load F is applied to the free end. Then, since the beam tends to be deformed so as to bend downward as a whole as indicated by a two-dot chain line in the figure, a force T in the tensile direction in the longitudinal direction of the beam acts on the connecting body 4 arranged on the upper surface of the beam. To do. The connecting body 4 can be cut with a cutter, that is, has an appropriate tensile strength, and has a predetermined cross-sectional area at the boundary between the block members 1 and 1, so that the force in the tensile direction is easy. It will not break. Similarly, in the both-end support beam model shown in FIG. 3B, if the connecting body 4 is arranged on the lower surface of the material body 3, a tensile force T can be applied to the connecting body 4 by the vertical load F. .

  Moreover, since there exists tensile strength and predetermined | prescribed cross-sectional area as above-mentioned, the connection body 4 is hard to fracture | rupture similarly to the force of a shear direction. Furthermore, since the block members 1 and 1 are in close contact with each other, the shearing force acting between the block members 1 and 1 of the connector 4 can be extremely reduced. That is, if attention is paid to a minute region located between the block members 1 and 1 of the connection body 4, the connection body 4 cannot be regarded as being in a state where both ends are supported by the block bodies 1 and 1. And the shear force which acts on what has both ends as a support point in this way changes according to the distance from the support point of the action point of the causative load. Therefore, when the block members 1 and 1 are in close contact with each other, the distance from the support point of the action point described above can be reduced as much as possible, and the shearing force can be extremely reduced. In addition to the above, since the adjacent block members 1 and 1 are in close contact with each other, it is difficult to shear even by frictional resistance generated between them.

  Therefore, according to the present invention, dimensional adjustment can be facilitated with a cutter. Further, according to the present invention, an appropriate strength can be secured without requiring special reinforcement in a structure that allows easy dimension adjustment.

  In the above structural material, the dimension in the stacking direction of each block material 1 may be determined to a size suitable for dimensional adjustment, and the block material 1 should have strength that can withstand an expected load. Good. For example, in the case of a shelf as in the conventional example, the material body 3 may be configured to have a total length of several tens of centimeters by laminating several tens of block materials 1 of several centimeters along the longitudinal direction of the shelf. Each block material 1 can be made of plate-like wood, metal, synthetic resin material, glass, ceramics, or the like.

  On the other hand, the connecting body 4 is sufficient if it has a tensile strength as described above, in other words, if it is difficult to deform in the tensile direction. The material and shape of the connection body 4 can be determined as appropriate in consideration of the tensile strength described above. For example, if the structural material is the above-described shelf board, the connecting body 4 can be made of paperboard, a film-like synthetic resin material having low ductility, a thin plate-like wood, or the like. In this case, if the connecting body 4 is arranged on the outer surface of the material main body 3 as a decorative board material that hides the boundary between the block materials 1 and 1 in the material main body 3 or makes it inconspicuous, for example, a decorative board, the decorativeness can be improved. Can be improved.

  Further, the bonding body 4 may be bonded to the material main body 3 using an appropriate adhesive according to the material of the connecting body 4 or the material main body 3.

  The above structural material is a structure in which the connecting body 4 is attached to the material main body 3 as exemplified in the above-mentioned cantilever model, and it is not always necessary to configure the entire length of the structural material. However, it is sufficient to provide only at one end or both ends in the required direction. Further, the block material 1 is not shaped like a plate in the above-described model, but is formed into a shape such as a cube, a quadrangular prism, a triangular prism, etc., and these are arranged in a planar shape or three-dimensionally and connected by an appropriate number of connectors 4. If the entire structural material is constructed, the dimensions can be adjusted simultaneously in a plurality of directions. In addition, all the block materials 1 constituting the material main body 3 can be uniformly adjusted with respect to all dimensions uniformly if the shape, size, and dimension in the stacking direction are the same. For example, when there is a pre-estimated dimension after adjustment, it is sufficient to mix different dimensions in the stacking direction. This can maintain the accuracy of dimension adjustment and reduce the bonding work during manufacturing. it can.

  Furthermore, if the connecting body 4 is attached to the opposing outer surface of the material body 3, not only the resistance to the load from the upper surface, that is, one direction, but also the resistance to the load in the opposite direction can be obtained like the above-mentioned cantilever. Therefore, the versatility can be improved, and the ease of use can be reduced because it is possible to reduce the trouble of determining the orientation of the structural material in consideration of the load direction, in other words, the arrangement of the coupling body 4. Furthermore, it is sufficient to determine the region in which the connecting body 4 is disposed according to the load direction. For example, if the region is disposed almost all over one side surface of the material main body 3, as described above, a predetermined boundary is provided between the block members 1 and 1. It is easy to secure a predetermined width that spans the cross-sectional area of the block material 1, but versatility can be further improved by arranging the block material 1 around the axis in the stacking direction.

  As is clear from the above description, according to the present invention, it is possible to provide a structural material with extremely simple dimensional adjustment, and it is possible to improve work efficiency such as installation work of the structural material requiring dimensional adjustment. .

FIG. It is a perspective view which shows a modification. It is a perspective view which shows other embodiment.

  1 and 2 show an embodiment of the present invention. This embodiment shows a case where the structural material A according to the present invention is used for a shelf board. In this embodiment, the material body 3 of the shelf board A is formed in a plate shape that is long in the stacking direction by stacking several tens of block materials 1, 1,... Is provided. Each block material 1 is a rectangular wooden board having a long side in the width direction of the shelf A and a short side in the thickness direction.

  In this embodiment, the connecting body 4 is a plate, and is formed to have a size approximately the same as the flat surface 2 of the material body 3 described above.

  In this embodiment, the shelf board A having the material main body 3 and the attached plate 4 is formed by bonding and fixing the plate 4 to almost the entire front or back surface of the material main body 3. A woodworking adhesive is used for this adhesive fixing.

  The material body 3 described above is manufactured, for example, by cutting wood that has been previously lumbered into a plate shape of approximately the same size, with a predetermined width along the longitudinal direction, and the manufacturing of the shelf board A is illustrated in FIG. As shown in FIG. 1, after pressing the longitudinal direction of the material body 3 obtained as described above with a vise or the like 12 to bring all the block members 1, 1,. It is made by adhering the plates 4 every two. In FIG. 1B, reference numeral 16 denotes a tube-like container that accommodates the adhesive 11.

  When the shelf board A manufactured as described above is used, the attachment plate 4 is cut with a cutter knife or the like according to the boundary position between the block members 1 and 1 so as to match the size of the installation location. The longitudinal dimension can be adjusted short. As shown in FIG. 2 (b), in this embodiment in which the support portion 13 that supports both ends of the shelf A from below is formed at the installation location, the shelf A after the dimension adjustment is attached to the support 13. If the board 4 is placed on the support portion 13 in a posture in which the plate 4 is directed, that is, in a posture in which the plate 4 is directed downward, the installation work is completed. In FIG. 2B, reference numeral 14 denotes a wall surface provided so that the shelf board A is interposed between the installation places of the shelf boards A.

  In addition, when the thickness of the block material 1 is slightly increased in consideration of manufacturing efficiency, when the dimensions of the installation location are irregular, the long side and the short side are the same size as each block material 1 and only the thickness is blocked. If a wood board thinner than the material 1 is prepared as the preliminary adjustment member 15, as shown in FIG. 2 (c), the shelf board A is installed with a size that is closer to the installation location by the preliminary adjustment member 15. Can do. In this case, it is sufficient that the shelf board A is configured to include an appropriate number of preliminary adjustment members 15.

  Moreover, in this embodiment, in order to facilitate the alignment between the cutting position of the clasp plate 4 and the boundary position between the block members 1 and 1 when the shelf plate A is cut, the clasp plate 4 is formed from the material body 3. Also, the width dimension is shortened so that both side edges 3a and 3a of the material body 3, that is, both ends of each block member 1 are exposed from the opposite edges of the plate 4. Further, the corners on the side plate 4 side of the side edges 3a and 3a of the shelf A are chamfered so that the boundary portion between the side plate 4 and the material body 3 is smoothed.

  Therefore, as shown in FIG. 2A by a dotted line, the shelf board A can be formed by connecting the boundaries of the block members 1 exposed from the opposite edges of the board 4 in a straight line and cutting the board 4. It can be easily cut at the boundary position between the block materials 1 and 1. In addition, the chamfering described above can be processed easily by processing the side edges 3a and 3a of the timber made into a plate shape having approximately the same size as the material body 3 before cutting out the block material 1. In addition, it is easy to align the attaching plate 4 to the material body 3 after that.

  In the above, the case where chamfering is performed only on the corner on the lower surface side of the side edge portion 3a of the shelf A is shown, but it is also possible to improve safety by chamfering the corner on the upper surface side. In addition to the chamfering of the corners, the chamfering may be performed in, for example, an arc shape.

  FIG. 4 shows a modification of the present invention. In addition, in this modified example and other embodiments described later, the same elements as those in the above-described embodiments are denoted by the same reference numerals in the drawings, and description thereof is omitted. In this modification, the plate 4 is bonded to both the front and back surfaces of the material body 3. Further, the shelf board A is chamfered at both upper and lower corners of the side edges 3a and 3a.

  Therefore, in this modified example, even if a force that causes the shelf A to bend upward is applied, it is difficult to break at the boundary position between the block members 1 and 1, and the orientation of the shelf A in the vertical direction during installation Can be saved. Moreover, the decorativeness of the upper surface of the shelf board A is enhanced by the board 4.

  FIG. 5 shows another embodiment of the present invention. This embodiment shows a case where the structural material according to the present invention is used for an appropriate floor plate A that is laid on a floor surface. In this embodiment, the floor plate A is formed in a square shape. The block material 1 is formed in a cubic shape, and the material main body 3 is configured by arranging a plurality of the block materials 1 in close contact with each other on the plane according to the width / length dimension of the floor plate A. In this embodiment, the connecting body 4 is configured as a decorative board that has an appropriate pattern on the surface to make it difficult to see the boundary between the block members 1 and 1, and is bonded to the upper surface of the material body 3. The Further, the corner on the decorative plate 4 side of the peripheral edge 3b of the material body 3 is chamfered.

  Therefore, in this embodiment, the width and length dimensions of the floorboard A can be adjusted at the same time by cutting the decorative plate 4 in accordance with the boundary positions of the block members 1 and 1 in the width direction and the length direction. it can.

  In the above-described embodiments, the case where the structural material of the present invention is used for the shelf board A and the floor board A has been shown, but it can also be applied to other uses such as table legs. is there.
