Description

This invention relates to shed surface structure constructed using wood corner structure assembled configuration with integrated corners.

  A wooden beam in a wooden building is a straight member, and this is pinned to each other via a pillar at the corner to provide a beam frame structure having corner portions such as L-shape, T-shape, and cross shape. Is configured. However, since this beam frame structure is pin-coupled as described above, braces, fire-fired, plywood, etc. must be placed in the corners to resist horizontal external forces (for example, patents) FIG. 13 of Document 1 and FIG. 3 of Patent Document 2).

  However, such braces, fire-firing, plywood, and the like impose restrictions on the degree of freedom of the plan when designing in consideration of wiping through, wiring, piping, and the like. In particular, fire resistance has a low horizontal resistance, and a high resistance horizontal resistance element is desired.

  As an invention that meets such a demand, there is a wood part joined body that is integrally formed in an L shape, a T shape, a cross shape, or the like as shown in FIGS. Since this is formed by cutting out a flat plate made of laminated wood so as to have the above-mentioned shape, the intersections of the straight lines of the above-mentioned respective shapes are an integral body having the same and continuous wood fibers.

Japanese Patent Laying-Open No. 2007-120164 (FIG. 13) Japanese Utility Model Publication No. 5-12517 (FIG. 3) JP 2012-202114 A (FIGS. 1 to 4)

  However, the above-mentioned prior art has a problem that it is brittle when a horizontal external force acts in the fiber direction because the intersecting portions are wood fibers of the same quality and continuous. In addition, since a flat plate made of laminated material must be cut into the above-mentioned shapes, there is a problem in that it takes time and effort to cut out, and the remaining plate material fragments are wasted and become uneconomical.

  The present invention has been made in order to solve the above-mentioned problems, and the means thereof is as follows.

According to the first aspect of the present invention, there is provided a first lamina member in which a fiber end face of one lamina and a fiber side face of the other lamina are joined at a substantially right angle, a fiber side face of the one lamina and a side face of the other lamina. A second laminar member joined to the end surface in the fiber direction at a substantially right angle is bonded to each other in the vertical direction via an adhesive and stacked to overlap each other, branched from the cross stacked portion A quadrangular frame is formed by connecting the beam joint laminated portions branched from the cross laminated portion of a plurality of wooden corner structure having two or more formed beam joint laminated portions to each other by a beam member. It is a shed surface structure in which a beam frame structure is supported by a pillar, and the wooden corner structure has a first lamina member and one lamina and the other lamina, One lamina of two lamina members and An L-shaped woody corner structure in which the other lamina is composed of one sheet, the first lamina member is composed of two of the one lamina and the other lamina is composed of one sheet, and the second lamina member And the one lamina and the other lamina both have a T-shaped woody corner structure composed of a single lamina, and the quadrangular frame has four L-shapes arranged at the corners of the four corners. The beam joint laminated portions of the wood corner structure are connected by the beam member, and the T-shaped wood corner structure is connected to the beam joint laminated portion and the beam in the middle of each opposing frame. The member is interposed so as to be joined to each other, and the beam joint laminated portions of the T-shaped woody corner portion structures facing each other are connected by the beam member.

According to a second aspect of the present invention, the joining of the end surface of one lamina and the side surface of the other lamina and the side surface of one lamina and the end surface of the other lamina in the first lamina member and the second lamina member is a finger joint. It is to be a thing.

According to a third aspect of the present invention, the joining of the end surface of the one lamina and the side surface of the other lamina and the side surface of the one lamina and the end surface of the other lamina in the first lamina member and the second lamina member The inclined surface formed on the end surface of the one lamina or the other lamina and the reverse inclined surface formed on the side surface of the other lamina or the one lamina are bonded together with an adhesive. is there.

In the invention according to claim 4 , the beam joint laminated portion and the beam member are joined by using a joint fitting having joining rods inserted on opposite facets of both the beam joint laminated portion and the beam member on both surfaces of the mounting plate. It is to join.

The invention according to claim 5 is such that the beam joint laminate and the beam member face each other by reversing the concave and convex portions formed by the length of the lamina at the opposite end faces of the beam joint laminate and the beam member. And joining them by fitting them through an adhesive.

The invention according to claim 6 is that the support of the beam frame structure by the pillar is to support the intersecting laminated portion of the wood corner structure.

  The woody corner structure according to the present invention includes a cross laminated portion formed by alternately laminating first and second lamina members in the vertical direction, and two or more beam joint laminated portions branched from the cross laminated portion. Therefore, a rigid joint structure can be formed if it is used for a cabin surface which is a beam frame structure constituting a rectangular frame of a wooden building. This eliminates the need for braces, fire-firing, plywood, and the like, which have been conventionally required, and thus has the advantage of increasing the degree of freedom in the plan for the cabin surface. In the cross-laminated portion of the first lamina member and the second lamina member that overlap in the vertical direction, laminaes having different fiber directions are alternately positioned in the vertical direction, and further, 2 constituting the upper and lower first lamina members and the second lamina member. In the above lamina, since the lamina wins or loses at the intersection, a rigid joint with higher strength can be obtained.

Further wood corner structure of the invention, L-shaped, be readily obtained by varying the fiber orientation of the number of laminae of laminae which constitutes the first and second lamina member ones of the T-shaped it can.

  Furthermore, in the case where the end surface of one lamina and the side surface of the other lamina are joined in the first and second lamina members, when a finger joint is employed, it can be easily formed by machining. In addition, when the inclined surface and the reverse inclined surface formed on the end surface of one lamina and the side surface of the other lamina are bonded together with an adhesive, the bonding area of the vertical surfaces is the same as the inclined surface. Since it becomes larger than the case, the bonding strength is improved.

Or, wood corner structure of the present invention, as described above in, L-shaped, so obtained those T-shaped beams of square frame by interconnection of a combination of these beam joint laminated portion and the beam member A frame structure can be obtained.

  If the beam joint laminate and the beam member are joined using the joint fitting, the beam joint laminate and the beam member are firmly joined by the intervention of the metal member. In addition, by forming irregularities on each end face depending on the length of the end of the lamina, and by facing these irregularities so as to be reversed and fitting and fixing via an adhesive, the beam joint laminated part without increasing the weight And beam members are joined.

  If this is built on the top floor of the building with pillars, a rigid structure can be obtained. This eliminates the need for braces, fire-firing, plywood, etc., so that the degree of freedom in planning such as providing a large blow-through or obtaining space for piping and wiring is improved. Moreover, when supporting by a pillar, support strength can be improved if it supports by a crossing laminated part.

  Embodiments of the present invention will be described below with reference to the drawings. First, the first embodiment shown in FIG. 1 will be described. The wood corner structure 1 is an L-shaped structure, and the first lamina member in which the end surface 2a in the fiber direction of one lamina 2 and the side surface 3b in the fiber direction of the other lamina 3 are joined at a substantially right angle. 4 is located in the uppermost stage, and then the second lamina member 5 in which the side face 2b in the fiber direction of one lamina 2 and the end face 3a in the fiber direction of the other lamina 3 are joined at a substantially right angle is located in the second stage. In the following description, the first lamina member 4 and the second lamina member 5 are alternately stacked in an up and down direction via an adhesive and are joined by applying pressure. That is, at the corner, the first lamina member 4 and the second lamina member 5 are laminated and joined alternately alternately in the opposite order. Here, one lamina 2 and the other lamina 3 are of the same shape having the same width, length and thickness. The width, thickness, and length are not particularly limited. These laminaes are thoroughly dried and polished before use to remove or disperse cracks, large joints, etc., so that they are not distorted or shrunk. Since timber pine, cypress, cedar and other domestic timber species and exotic timber species are sawn into a sawn board, the longitudinal direction is generally ground in the fiber direction to form end faces 2a and 3a at both ends. Side surfaces 2b and 3b are formed.

As described above, the wooden corner structure 1 in which the first lamina member 4 and the second lamina member 5 are alternately laminated in an up and down direction via an adhesive and laminated to each other is joined at a substantially right angle. In the intersecting portion 6 , the fiber directions of the upper and lower lamina are different, and the joints are different in winning and losing, so that a rigid body structure is formed. And the cross lamination part 7 which two lamina cross | intersects, and it has branched from this cross lamination part 7, and has comprised two beam joint lamination parts 8 in the orthogonal | vertical direction.

  As shown in FIG. 2, the first embodiment of the joining of one lamina 2 and the other lamina 3 of the first lamina member 4 is a fiber end face 2a of one lamina 2 and fibers of the other lamina 3 as shown in FIG. An uneven shape 9 is formed to be a finger joint corresponding to each of the side surfaces 3b in the direction. And when joining these as a finger joint, it is only necessary to superimpose on the uneven | corrugated shape 9 part via an adhesive agent.

  In the second embodiment, as shown in FIG. 3, the inclined surface 10 is formed on the end surface 2 a in the fiber direction of one lamina 2, and the same angle as the inclined surface 10 is formed on the side surface 3 b in the fiber direction of the other lamina 3. The reverse inclined surface 11 is formed, and the inclined surface 10 and the reverse inclined surface 11 are overlapped and bonded together with an adhesive. The first embodiment and the second embodiment may be joined by different joints in the upper and lower stages. The joining of the two laminaes in the first and second examples is the same in the second and third embodiments described below.

  After the first lamina member 4 and the second lamina member 5 as described above, if one lamina 2 and the other lamina 3 are the same shape and the same material, the first lamina member 4 is turned over. When rotated 90 degrees, the second lamina member 5 is produced. Therefore, only the first lamina member 4 is produced, and the upper and lower surfaces are alternately turned upside down and rotated 90 degrees to overlap each other with an adhesive interposed therebetween. However, since it is an operation that only applies pressure and pastes, it can be produced very efficiently.

  A second embodiment of the woody corner structure 1 of the present invention will be described with reference to FIG. The woody corner structure 1 of the second embodiment is a T-shaped structure, and one lamina 2 has two sheets 2A and 2B, and the end faces 2Aa and 2Ba in the respective fiber directions and the other The first lamina member 1 joined at substantially right angles at the ends of the two opposite side surfaces 3b in the fiber direction of the lamina 3 is positioned at the uppermost stage, and then the center of the side surface 2a in the fiber direction of one lamina 2 In the portion, the second lamina member 5 which is joined to the end surface 3a in the fiber direction of the other lamina 3 at a substantially right angle is located in the second stage, and hereinafter, the first lamina member 4 and the second lamina member 5 are alternately arranged Are stacked in an up-and-down direction with an adhesive, and bonded by applying pressure. In FIG. 4, the joint portion of the second lamina member 5 does not appear. That is, the 1st lamina member 4 and the 2nd lamina member 5 are laminated | stacked by superposing | stacking alternately by reversing victory and defeat, and were joined by applying a pressure. Here, one lamina 2 and the other lamina 3 are different in number and length in the first lamina member 4 and the second lamina member 5, but the width and thickness are the same.

  In the woody corner structure 1 of the second embodiment, as in the first embodiment, at the intersection 6 where the upper and lower first lamina members 4 and the second lamina member 5 are joined, Since the fiber directions of the lamina are different and the joints are different in winning and losing, a rigid structure is formed. The cross laminated portion 7 and three beam joint laminated portions 8 branched from the cross laminated portion 7 and equidistant from each other in the perpendicular direction are provided.

  A third embodiment of the woody corner structure 1 of the present invention will be described with reference to FIG. The woody corner structure 1 according to the third embodiment is a cross-shaped structure, and the first lamina member 4 located at the uppermost stage is composed of two lamina 2 2A and 2B. The end surfaces 2Aa, 2Ba in the fiber direction of one lamina 2A, 2B are joined to the both side surfaces 3b of the central portion in the fiber direction of the other lamina 3 whose length is longer than that of one lamina 2.

Two other laminaes 3A and 3B having end faces 3Ab and 3Bb. Such a first lamina member 4 and a second lamina member 5 are alternately laminated in the vertical direction via an adhesive and joined by applying pressure. Here, the first lamina member 4 and the second lamina member 5 are joints in which one lamina 2 and the other lamina 3 are different from each other. At the intersection 6 in such joining, since the fiber directions of the upper and lower lamina are different and the winning and losing are different, a rigid structure is formed as in the first and second embodiments. The cross laminated portion 7 and four beam joint laminated portions 8 branched from the cross laminated portion 7 and equidistant from each other in the perpendicular direction are provided.

  An example of joining the beam joint laminated portion 8 of the wood corner structure 1 and the beam member 12 made of laminated material in the first to third embodiments will be described with reference to FIGS. This joining example is an example performed using the joining fitting 13 shown in FIGS. 6 and 7, and the joining fitting 13 is provided with two joining rods 13b on each of the upper, middle, and lower stages from both side surfaces of the mounting plate 13a. It is fixed so that it protrudes. Then, as shown in FIGS. 5 and 7, the end surfaces of the beam joint laminated portion 8 and the beam member 12 are inserted into the insertion holes 8a and 12a of the connecting rod 13b at positions corresponding to the mounting positions of the connecting rod 13b. Is formed. At the time of joining, the joining rod 13b is first inserted into the insertion hole 8a opened on the end face of the beam joint laminated portion 8 with the joining fitting 13 interposed therebetween, and then the insertion opened on the end face of the beam member 12 This is done by inserting the other side joining rod 13b into the hole 12a. The order of insertion may be simultaneous or reverse. Prior to insertion, bonding strength is further improved by applying an adhesive to the mounting plate 13a and the insertion hole 13b.

  Another example of joining the beam joint laminated portion 8 and the beam member 12 will be described with reference to FIGS. In this joining example, the end surfaces 2Aa and 2Bb of one lamina 2A and 2B constituting the beam joint laminated portion 8 are connected to the first lamina member 4 and the second step as shown in FIG. As shown in FIG. 9, the end faces of the lamina formed by the beam members 12 that are joined to the second lamina member 5 located at the bottom are alternately shortened in order from the top as shown in FIG. By laminating both laminated laminas in the same manner with the lengths reversed, as shown in Fig. 10, the concavities and convexities formed on both end faces are reversed and fitted through an adhesive. It is fixed. In the above two examples, the T-shaped structure has been described, but the same applies to the joining with the beam member in the L-shaped or cross-shaped structure. Of course, bonding other than the two examples described above may be used.

For example to build a shed surface 14 with wood corner structure 1 of the first to third embodiments described above, it will be described with reference to FIG. The quadrangular frame 15 has four L-shaped wooden corner structures 1 of the first embodiment arranged at the corners of the four corners, and these four L-shaped wooden corner structures 1 are formed by beam members 12.
