Description

The present invention relates to structural members.

Conventionally, when joining intersecting members to form a structural member such as a column or a beam, for example, the intersecting members are joined via a plate by a bolt. For this reason, the structure of the intersection (joint portion) of the structural member is complicated.

In order to solve this problem, for example, in Patent Document 1, an end member having an intersection is formed by laminating a plurality of laminar materials orthogonal to each other, and a structural member is formed by joining an assembly column to the end member. The configuration to be used is disclosed. However, in Patent Document 1, since the laminated columns are bolted to the intersections of the end members, the structure of the intersections of the structural members is complicated.

Hereinafter, as an example of the structural member according to the embodiment of the present invention, a face material formed by a plurality of intersecting members will be described with reference to FIGS. 1 to 3.

(Cross member)
As shown in FIG. 1, the prestructure unit 10 as a crossing member is a laminated wood in which a plurality of laminar materials 12 and 14 are laminated, and the angle (acute angle) formed by the laminar materials 12 and 14 is about 60 in a plan view. It has an approximately X-shaped shape with °.

Specifically, a plate member 16 in which a pair of divided laminar members 12 extending in one direction are butted so as to intersect the side surfaces of a through laminar member 14 extending in the other direction, and a pair of divided laminars extending in the other direction. A plate member 18 is formed by abutting the member 14 so as to intersect the side surface of the through laminar member 12 extending in one direction. Then, the plate material 16 and the plate material 18 are alternately laminated and a plurality of plates are laminated to form the prestructure unit 10.

The laminar materials 12 and 14 are laminated so that the fiber directions intersect. Further, the intersecting portion where the laminar materials 12 and 14 are butted against each other is referred to as the intersecting portion 20 of the prestructure unit 10.

Further, as will be described in detail later, the groove 22 and the widening portion 22A provided in the groove 22 are formed at both ends of the laminar materials 12 and 14 in the longitudinal direction, and the groove 22 and the widening portion 22A are formed. The end portion of the structure unit 10 is a joint portion 24. After laminating the laminar materials 12 and 14 to form the prestructure unit 10, the groove portion 22 and the widening portion 22A may be formed at the end of the prestructure unit 10.

(Face material)
As shown in FIG. 2, the lattice-shaped face material 26 is formed by connecting the ends of the plurality of prestructure units 10 on a plane. The face material 26 is, for example, a floor material or a wall material of a building.

In the present embodiment, a triangular space 28 and hexagonal spaces 30A and 30B are formed by a lattice composed of a plurality of prestructure units 10, and the face material 26 is a combination of a truss structure and a honeycomb structure. It is said to have a structure.

Further, in the lattice forming the space 30A, as an example of the reinforcing member, a kumite unit 32 composed of a plurality of (three in the present embodiment) kumite 32A is fitted. The kumite 32A is a piece of wood whose both ends are pointed (the tip angle is about 120 ° in a plan view), one end of which is in contact with the intersection 20 of the prestructure unit 10, and the other end of which is space 30A. They are in contact with each other at the center of the.

Here, since the kumite unit 32 is formed to have a slightly larger size, a reaction force acts on the abutting prestructure unit 10 when it is fitted in the lattice (space 30A). Therefore, it can be fixed in the lattice only by fitting the kumite unit 32.

Further, in the lattice forming the space 30B, as another example of the reinforcing member, a reinforcing unit composed of a prestructure unit 34 and a kumite 38 joined to a joint portion 36 of the prestructure unit 34, respectively. 40 is fitted.

The prestructure unit 34 has the same configuration as the prestructure unit 10 constituting the face material 26. Further, the kumite 44 is also fitted between the intersection 20 of the prestructure unit 10 and the intersection 42 of the prestructure unit 34.

(Joint part)
The joint portion 24 of the prestructure unit 10 is joined to each other via a hiring member 46 which is a separate member. Specifically, as shown in FIG. 3, a groove portion 22 is formed on the end surface of the prestructure unit 10 (joint portion 24) along the thickness (height) direction of the prestructure unit 10.

Both ends of the groove portion 22 are open to the upper surface and the lower surface of the joint portion 24 of the prestructure unit 10, respectively, and the bottom portion of the groove portion 22 is provided with a widening portion 22A having a width larger than the width of the groove portion 22.

Further, on the end surface of the prestructure unit 10 (joint portion 24), a pair of fitting grooves 48 are formed at both ends in the width direction sandwiching the groove portions 22. Further, two insertion holes 52 into which the pin 50 is inserted are formed through the side surface of the joint portion 24 (the side surface of the groove portion 22) of the prestructure unit 10.

On the other hand, the hiring material 46 is a laminated wood in which a plurality of laminar materials 54 are laminated, and thick-walled portions 46A fitted into the widening portion 22A of the groove portion 22 are provided at both ends in the longitudinal direction. Further, four insertion holes 56 into which the pins 50 are inserted are formed through the side surfaces of the hiring material 46.

(Action and effect)
When forming the face material 26, first, as shown in FIG. 1, the prestructure unit 10 is formed by laminating a plurality of laminar materials 12 and 14.

After that, as shown in FIG. 3, the dowel material 58 is fitted between the fitting groove 48 of the joint portion 24 of one prestructure unit 10 and the fitting groove 48 of the joint portion 24 of the other prestructure unit 10. Then, the positions of the joint portions 24 are aligned with each other.

Then, the hiring material 46 is fitted into the groove portion 22 of the joint portion 24 of the one and the other prestructure unit 10 from the upper surface side, and a pin is inserted so as to penetrate the insertion hole 52 of the joint portion 24 and the insertion hole 56 of the hiring material 46. Insert 50. By the above steps, the joint portions 24 of the plurality of prestructure units 10 are fixed to each other to form the face material 26 shown in FIG.

After that, by joining wooden plates (not shown) to both sides of the face material 26, it is possible to form a wall surface or a floor surface of a building having a truss structure or a honeycomb structure. The material of the plate may be a metal such as iron or aluminum. Further, as a method of joining the plate to the face material 26, various methods such as a method of adhering with an adhesive and a method of fixing with screws or nails can be used.

According to the present embodiment, the prestructure unit 10 is configured by laminating a plurality of laminar materials 12 and 14. Therefore, the intersection 20 of the prestructure unit 10 can be rigidly joined, and the strength can be increased.

Further, since the plurality of prestructure units 10 are connected to each other by the joint portions 24 provided at the end portions, the structure of the intersection portion 20 of the prestructure unit 10 can be simplified.

Further, according to the present embodiment, the face material 26 is formed by connecting a plurality of prestructure units 10 having the same shape on a plane. Therefore, the face material 26 can have a truss structure or a honeycomb structure, and the strength can be increased. Further, by sharing the prestructure unit 10, it is possible to improve the efficiency of processing and construction.

Further, according to the present embodiment, the kumite unit 32 and the reinforcing unit 40 are fitted in the spaces 30A and 30B of the face material 26. Therefore, the rigidity of the face material 26 can be increased, and the kumite unit 32 and the reinforcing unit 40 can be used as a stress transmission path applied to the face material 26.

When the kumite unit 32 and the reinforcing unit 40 are fitted into the spaces 30A and 30B, prestress is applied to the prestructure unit 10 that comes into contact with the kumite unit 32 and the reinforcing unit 40 due to the reaction force. Therefore, the strength of the face material 26 can be further increased.

Further, according to the present embodiment, it can be fixed only by fitting the kumite unit 32 and the reinforcing unit 40 into the spaces 30A and 30B, and the hiring material 46 is fitted into the groove 22 to insert the insertion holes 52 and 56. The joint portions 24 can be fixed to each other simply by inserting the pin 50 into the joint portion 24. That is, since the face material 26 can be formed without using a joining member such as a bolt, the joining structure of the face material 26 can be simplified.

(Other embodiments)
Although an example of the embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and various other embodiments are possible within the scope of the present invention.

In the above embodiment, the face material 26 is formed by the substantially X-shaped prestructure unit 10, but the shape and size of the prestructure unit 10 can be appropriately determined by the structural member to be formed, and the above embodiment Is not limited.

For example, a column and a beam can be formed by a prestructure unit by laminating the laminar material constituting the column and the lamina material constituting the beam at right angles. In this case, by connecting a plurality of prestructure units constituting columns and beams, a structural surface of a rigid frame structure can be formed as another example of the structural member.

Further, in the above embodiment, the kumite unit 32 and the reinforcing unit 40 as the reinforcing members are fitted and fixed in the lattice of the face material 26, but the configuration of the reinforcing member is not limited to the above embodiment. .. For example, after inserting a wooden reinforcing member into which prestress (compressive force) has been introduced into the lattice, the reinforcing member is fixed in the lattice by self-crimping force by releasing the prestress (compressive force) of the reinforcing member. It may be configured to be used.

Further, the hexagonal reinforcing member may be fitted in the lattice so as to cover the entire surface of the spaces 30A and 30B. Further, the position where the reinforcing member is provided in the face material 26 is also appropriately determined. Therefore, for example, the strength of the face material 26 can be partially increased by providing the reinforcing member at a position where the applied stress is large. The reinforcing member can be moved or added later.

Further, in the above embodiment, both ends of the groove portion 22 formed on the end surface of the prestructure unit 10 (joint portion 24) are opened to the upper surface and the lower surface of the joint portion 24, respectively. However, one of the ends of the groove 22 may be an open end and the other may be a closed end. In this case, the closed end of the groove 22 serves as a guide for receiving the hiring material 46 inserted from the open end of the groove 22.

Further, for example, by forming a convex portion on one side and a concave portion on the other side of the joint portion 24 and fitting the convex portion and the concave portion, the joint portions 24 are directly joined to each other without using another member such as a hiring member 46. It may be configured to be made to.

Further, by connecting the prestructure units 10 at right angles to each other, it is possible to form two structural surfaces such as a wall material and a floor material, and further, adjusting the connection angle between the prestructure units 10. Therefore, it is also possible to construct an arch-shaped structure surface.
