Description

  The present invention relates to a structural member.

  2. Description of the Related Art Conventionally, when crossing members are joined to form a structural member such as a column or a beam, the crossing members are joined with bolts, for example, via a plate. For this reason, the structure of the crossing part (joint part) of the structural member is complicated.

  In order to solve this problem, for example, in Patent Document 1, an end member having an intersecting portion 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 structure to perform is disclosed. However, in patent document 1, since the assembly column was joined to the intersection part of the end member with the volt | bolt, the structure of the intersection part of a structural member was complicated.

  In view of the above-described facts, an object of the present invention is to provide a structural member capable of simplifying the structure of the intersection while increasing the strength of the intersection.

  The structural member according to claim 1 is configured by a plurality of lamina materials stacked so as to intersect with each other, an intersection portion where the lamina materials intersect, a joint portion formed at an end of the lamina material, The joint portions of the plurality of cross members are joined to each other.

  According to the said structure, the cross member is comprised by the lamina laminated | stacked so that it might mutually cross | intersect. For this reason, the intersection part which is the intersection part of a lamina material can be made into a rigid junction, and the intensity | strength of an intersection part can be raised.

  Moreover, a joint part is formed in the edge part of a cross member (lamina material), and a structural member is formed by the cross member by which the joint parts were joined. That is, since the crossing members are connected at a portion other than the crossing portion, the structure of the crossing portion can be simplified.

  A structural member according to a second aspect is the structural member according to the first aspect, wherein a lattice-shaped face material is formed by the plurality of intersecting members.

  According to the above configuration, since a face material such as a ramen structure or a truss structure can be formed by joining a plurality of cross members, the strength of the face material can be increased. In addition, by making the cross member common as a unit, the efficiency of processing and construction can be improved.

  In the present invention, the “lattice shape” refers to a shape having a plurality of spaces separated by cross members, and in addition to the cross lattice shape in which the lamina materials of the cross members are orthogonal to each other, the lamina materials of the cross members are An oblique lattice shape that obliquely intersects each other is also included.

  A structural member according to a third aspect is the structural member according to the second aspect, comprising a reinforcing member fitted into a lattice of the face material.

  According to the above configuration, the reinforcing member is fitted into the lattice of the face material, thereby reinforcing the face material and prestressing the surrounding cross members. For this reason, the intensity | strength of a face material can be raised more.

  According to the present invention, the structure of the intersection can be simplified while increasing the strength of the intersection.

It is a disassembled perspective view which shows the cross member which comprises the structural member in an example of embodiment of this invention. It is a top view which shows the face material which is a structural member in an example of embodiment of this invention. It is an expansion perspective view which shows the joint part of a cross member.

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

(Cross member)
As shown in FIG. 1, the prestructure unit 10 as a cross member is a laminated material in which a plurality of lamina materials 12 and 14 are laminated, and an angle (acute angle) formed by the lamina materials 12 and 14 in a plan view is about 60. It is made into the substantially X shape made into °.

  Specifically, a pair of divided lamina 12 extending in one direction and a pair of divided lamina 12 extending in the other direction, and a plate member 16 that is butted so as to intersect a side surface of a laminar material 14 that extends in the other direction. A plate material 18 is formed by abutting the material 14 so as to intersect the side surface of the laminar material 12 extending in one direction. And the pre-structure unit 10 is formed by laminating | stacking the board | plate material 16 and the board | plate material 18 alternately, and bonding several sheets.

  In addition, the lamina materials 12 and 14 are laminated | stacked so that a fiber direction may cross | intersect. In addition, the intersection where the lamina members 12 and 14 are abutted with each other is the intersection 20 of the prestructure unit 10.

  Further, as will be described in detail later, groove portions 22 and widened portions 22A provided in the groove portions 22 are formed at both ends in the longitudinal direction of the lamina materials 12 and 14, and the pre-formed portions having the groove portions 22 and the widened portions 22A formed thereon. An end portion of the structure unit 10 is a joint portion 24. In addition, after laminating the lamina materials 12 and 14 to form the prestructure unit 10, the groove 22 and the widened portion 22 </ b> A may be formed at the end of the prestructure unit 10.

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

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

  In addition, in the lattice forming the space 30A, a hand unit 32 constituted by a plurality of (three in this embodiment) hand 32A as an example of a reinforcing member is fitted. The assembled hand 32A is a piece of wood with both ends being pointed (the tip angle is about 120 ° in plan view), one end abutting against the intersecting portion 20 of the prestructure unit 10, and the other end being a space 30A. Are in contact with each other at the center.

  Here, since the hand unit 32 is formed to have a slightly larger size, a reaction force acts on the abutting prestructure unit 10 when fitted into the lattice (space 30A). For this reason, it can fix in a lattice only by fitting the hand unit 32.

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

  The prestructure unit 34 has the same configuration as that of the prestructure unit 10 constituting the face material 26. In addition, a pair of hands 44 is also inserted between the intersection 20 of the prestructure unit 10 and the intersection 42 of the prestructure unit 34.

(Fitting part)
The joint portions 24 of the prestructure unit 10 are joined to each other via a hiring material 46 that 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 opened to the upper surface and the lower surface of the joint portion 24 of the prestructure unit 10, respectively, and a widened portion 22 </ b> A having a width larger than the width of the groove portion 22 is provided at the bottom portion of the groove portion 22.

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

  On the other hand, the hiring material 46 is a laminated material in which a plurality of lamina materials 54 are laminated, and thick portions 46A that are fitted into the widened portions 22A of the groove portions 22 are provided at both longitudinal ends. Further, four insertion holes 56 into which the pins 50 are inserted are formed through the side surface of the hiring material 46.

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

  Thereafter, as shown in FIG. 3, a 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. Thus, the positions of the joint portions 24 are aligned.

  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 the pin is inserted through the insertion hole 52 of the joint portion 24 and the insertion hole 56 of the hiring material 46. 50 is inserted. The face material 26 shown in FIG. 2 is formed by fixing the joint portions 24 of the plurality of prestructure units 10 through the above-described steps.

  Thereafter, by joining wooden plates (not shown) to both sides of the face material 26, the wall surface and floor surface of the building having a truss structure or a honeycomb structure can be formed. The plate material may be a metal such as iron or aluminum. As a method for joining the plate to the face material 26, various methods such as a method of bonding 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 lamina materials 12 and 14. For this reason, the crossing part 20 of the prestructure unit 10 can be made into a rigid joint, and the strength can be increased.

  Furthermore, since the plurality of prestructure units 10 are connected by the joint portions 24 provided at the end portions, the structure of the intersecting 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. For this reason, the face material 26 can have a truss structure or a honeycomb structure, and the strength can be increased. Further, by making the prestructure unit 10 common, it is possible to improve the efficiency of processing and construction.

  Further, according to the present embodiment, the hand unit 32 and the reinforcing unit 40 are fitted into the spaces 30 </ b> A and 30 </ b> B of the face material 26. For this reason, the rigidity of the face material 26 can be increased, and the assembly unit 32 and the reinforcing unit 40 can be used as a transmission path for stress applied to the face material 26.

  Note that when the hand unit 32 and the reinforcing unit 40 are fitted into the spaces 30A and 30B, prestress is applied to the prestructure unit 10 that contacts the hand unit 32 and the reinforcing unit 40 due to reaction force. For this reason, the strength of the face material 26 can be further increased.

  Furthermore, according to the present embodiment, it is possible to fix the space 30A, 30B simply by fitting the assembly unit 32 and the reinforcing unit 40, and to insert the hiring material 46 into the groove 22 to insert the insertion holes 52, 56. By simply inserting the pin 50 into the joint portion 24, the joint portions 24 can be fixed. 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)
As mentioned above, although an example of embodiment was demonstrated about this invention, this invention is not limited to this embodiment, Various other embodiment is 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. However, the shape and size of the prestructure unit 10 can be appropriately determined depending on the structural member to be formed. Is not limited.

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

  Moreover, in the said embodiment, although the hand unit 32 and the reinforcement unit 40 as a reinforcement member were inserted and fixed in the grating | lattice of the face material 26, the structure of a reinforcement member is not restricted to the said embodiment. . For example, after inserting a wooden reinforcement member with prestress (compression force) introduced into the lattice, the prestress (compression force) of the reinforcement member is released, so that the reinforcement member is fixed in the lattice by self-crimping force. It is good also as composition to do.

  Further, the hexagonal reinforcing member may be configured to be fitted into the lattice so as to cover the entire surfaces of the spaces 30A and 30B. Furthermore, the position where the reinforcing member is provided in the face material 26 is also appropriately determined. For this reason, the intensity | strength of the face material 26 can be partially improved by providing a reinforcement member in the position where the applied stress is large, for example. The reinforcing member can be moved or added later.

  Moreover, in the said embodiment, the both ends of the groove part 22 formed in the end surface of the prestructure unit 10 (joint part 24) were each open | released by the upper surface and lower surface of the joint part 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 of the joint portion 24 and a concave portion on the other side and fitting the convex portion and the concave portion together, the joint portions 24 are directly joined without using another member such as the hiring material 46. A configuration may be adopted.

  In addition, by connecting the prestructure units 10 orthogonally, it is possible to configure two construction surfaces such as a wall material and a flooring, and to adjust the connection angle between the prestructure units 10. Thus, it is possible to form an arched surface.
