Description

[Technical field]

[0001] The present invention relates to a wooden frame structure. [Background technology]

[0002] In wooden frame construction using the wooden frame method, the most common methods are to join wooden panels such as structural plywood as load-bearing walls with nails or to install braces inside a frame made up of wooden columns and structural members (wooden frame members) such as wooden beams or foundations. In the solid wall type, wooden frame construction is formed by fastening wooden panels to structural members with fasteners such as nails or screws via receiving materials, while in the large wall type, wooden frame construction is formed by fastening wooden panels directly to structural members with fasteners. Regardless of the type of wooden frame construction, it is common to use a large number of fasteners when forming a wooden frame construction that forms a high-strength load-bearing wall.

[0003] However, when a wooden panel is joined to a structural member using a large number of fasteners, it is easy to imagine that the ultimate strength will be greater than the design strength (strength at short-term allowable stress design) of the wooden frame structure. With this increase in ultimate strength, for example, stress will increase at the joint between the structural member, the column, and the wooden panel, and the joint may fail first. Furthermore, when the width of a wooden frame structure is narrow, the rigidity of the bearing wall decreases, so the ultimate strength tends to be even higher than the design strength, and the failure of the joint first becomes more pronounced.

[0004] For these reasons, it is desirable for a wooden frame structure in which wooden panels are attached to wooden structural members to have high rigidity at the joints between the structural members and the wood panels and to have an inhibited increase in ultimate strength.

[0005] Here, Patent Document 1 proposes a thin steel plate wall material to be joined and fixed to a wooden building frame and a method for joining and fixing them. Specifically, in a wooden building frame consisting of each axis member such as a pillar, stud, beam, girder, joist and foundation, the wall surface of the wooden building frame and each axis member are covered, and a thin steel plate wall material is joined and fixed to each axis member, so that the thin steel plate wall material forms a load-bearing wall together with the wooden building frame and replaces or reinforces the braces. The joining and fixing positions indicated in advance on the surface of the thin steel plate wall material are set so that they become closer toward the joint parts of each axis member of the wooden building frame.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 11-172812 Summary of the Invention [Problem to be solved by the invention]

[0007] According to the thin steel plate wall material joined and fixed to the wooden building frame described in Patent Document 1, since it is joined to each axis member of the wooden building frame with a large number of nails, screws, etc., it is possible to form a high-strength load-bearing wall. However, there is a problem as mentioned above, that is, there is a risk of premature failure of the joint due to increased stress at the joint.

[0008] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a wooden frame structure in which wood panels are attached to wooden structural members, in which the joints between the structural members and the wood panels have high rigidity and the increase in ultimate strength is suppressed. [Means for solving the problem]

[0009] In order to achieve the above object, one aspect of the wooden frame structure according to the present invention is as follows: A wooden frame structure in which a wooden panel is attached to a frame having wooden structural members, which are columns, cross members including beams and foundations, The present invention is characterized in that the columns and / or cross members and the wood panels are joined directly or indirectly with fasteners via protruding plates.

[0010] According to this aspect, the columns and / or cross members and the wooden panels are joined directly or indirectly with fasteners via the protruding plate, so that it is possible to form a joint between a structural member and a wooden panel that is highly rigid and has a suppressed increase in ultimate strength while minimizing the number of fasteners such as nails and screws. That is, the protrusions of the protruding plate penetrate the structural member or the wooden panel, increasing the sliding rigidity at the interface between the two, so that it is possible to increase the rigidity of the joint while reducing the number of fasteners such as nails. By suppressing the increase in ultimate strength relative to the design strength (strength at the time of short-term allowable stress design), it is possible to suppress the increase in stress at the joint. In addition, since it is possible to reduce the number of fasteners such as nails as much as possible, the workability of the wooden frame structure is improved.

[0011] Here, "the columns and / or cross members are joined to the wood panel via a protruding plate" means a configuration in which only the columns are joined to the wood panel, a configuration in which only the cross members (beams) are joined to the wood panel, a configuration in which only the cross members (base) are joined to the wood panel, a configuration in which the wood panel is joined to any two types of structural members, and a configuration in which the wood panel is joined to all three types of structural members.

[0012] For example, in a configuration in which a column and a wooden panel are joined via a protruding plate, a beam or a base and a wooden panel may be joined by fasteners such as nails or tenon pipes without using a protruding plate. In particular, when a tenon pipe is used, it is preferable because the tenon pipe can bear the shear force generated in the wooden panel.

[0013] In addition, "the structural member and the wooden panel are joined directly or indirectly with fasteners via a protruding plate" means both a form in which the structural member and the wooden panel are directly joined with fasteners via a protruding plate, and a form in which the structural member and the receiving material are joined with fasteners, and the receiving material, the protruding plate, and the wooden panel are joined with fasteners, thereby indirectly joining the structural member and the wooden panel with the receiving material and the protruding plate. More specifically, in this specification, "directly" means a form in which the structural member and the wooden panel are joined without a receiving material (the interposition of a protruding plate is acceptable), and "indirectly" means a form in which the structural member and the wooden panel are joined with a receiving material (the interposition of a protruding plate is also acceptable).

[0014] The wooden frame structure of this embodiment is a structure that can form a load-bearing wall by using wooden panels, and can be either a solid wall type or a large wall type. The fasteners can be bolts, screws, nails, drift pins, etc. The wooden panels can be structural plywood, laminated timber (material in which multiple pieces of lumber are fixed together with adhesives, screws, etc.), CLT (Cross Laminated Timber) panels, etc.

[0015] When the wooden panels are CLT panels, for example, a wide range of panels with dimensions up to 12m x 2.6m can be used, which reduces the number of connections between panels on-site as much as possible, thereby improving the strength and ease of construction of wooden framework structures. In addition, CLT panels are made of multiple boards laminated with their fibers crossed (orthogonal), making them resistant to deformation and suitable for use as load-bearing walls.

[0016] In another aspect of the wooden frame structure according to the present invention, The protrusion plate is provided with a plurality of protrusions formed on both of a pair of wide surfaces of a steel plate by scraping up a plurality of notches in the plate; The method is characterized in that the multiple protrusions on each of the pair of wide surfaces are inserted into the columns and / or cross members and wood panels that are joined to each other.

[0017] According to this embodiment, the protrusion plate has multiple protrusions formed by scraping up multiple notches in the plate on both of a pair of wide sides of the steel plate, so that a structure that penetrates both the structural member and the wooden panel can be formed by simply processing a single steel plate, and a joint between the structural member and the wooden panel that is highly rigid and has a suppressed increase in ultimate strength can be formed at the lowest possible manufacturing cost.

[0018] Another aspect of the wooden frame structure according to the present invention is as follows: A portion of the wood panel is arranged on the side of the structural member with the protruding plate in between, and the fastener that passes through the wood panel and the protruding plate reaches the structural member.

[0019] According to this embodiment, a portion of the wood panel is arranged on the side of the structural member with a protruding plate in between, and each member is joined with a common fastener, thereby directly joining the structural member and the wood panel, thereby forming a joint between the structural member and the wood panel that is highly rigid and has a suppressed increase in ultimate strength.

[0020] Another aspect of the wooden frame structure according to the present invention is as follows: A groove is provided on a side surface of the frame member, The groove accommodates the protruding plate and the end of the wood panel in that order, and the side surface and the wood panel are flush with each other.

[0021] According to this embodiment, the protruding plate and the end of the wood panel are sequentially accommodated in a groove provided on the side of the structural member and joined with fasteners, and since the side of the structural member and the wood panel are flush with each other, the surfaces of the structural member and the wood panel are continuous, forming a joint with excellent external design.

[0022] Another aspect of the wooden frame structure according to the present invention is as follows: The end of the wood panel is abutted against the side of the frame member, A support is provided on the side surface of the frame member, The protruding plate is interposed between the frame member and the receiving member, The separate protruding plate is interposed between the receiving material and the wood panel, The fastener that passes through the wood panel and the protruding plate reaches the receiving material, and another fastener that passes through the receiving material and the protruding plate reaches the structural member.

[0023] According to this embodiment, a portion of the wood panel is arranged on the side of the structural member with a protruding plate in between and joined with a common fastener, and a separate protruding plate is interposed between the receiving material and the wood panel and joined with a separate common fastener, thereby indirectly joining the structural member and the wood panel and forming a joint between the structural member and the wood panel that is highly rigid and has a suppressed increase in ultimate strength.

[0024] Another aspect of the wooden frame structure according to the present invention is as follows: The front view shape of the wood panel is rectangular, The four corners of the rectangle are cut out.

[0025] According to this embodiment, the four corners of the rectangular wooden panel when viewed from the front are notched, so that when the wooden frame structure is deformed during an earthquake, the corners of the wooden panel come into contact with beams, foundations, etc., and are pressed against each other, preventing an increase in ultimate strength due to compressive forces. Effect of the Invention

[0026] As can be understood from the above explanation, according to the wooden frame structure of the present invention, it is possible to provide a wooden frame structure in which wood panels are attached to wooden structural members, in which the joints between the structural members and the wood panels have high rigidity and the increase in ultimate strength is suppressed.

[0028] Hereinafter, an example of a wooden frame structure according to an embodiment will be described with reference to the accompanying drawings. In this specification and the drawings, substantially identical components are designated by the same reference numerals to avoid redundant description.

[0029] [Wooden frame structure according to the embodiment] An example of a wooden frame structure according to an embodiment will be described with reference to Fig. 1 to Fig. 7. Fig. 1 is a front view of the example of the wooden frame structure according to the embodiment, Fig. 2 is a cross-sectional view of the example of the wooden frame structure according to the embodiment taken along line II-II in Fig. 1. Fig. 3 is a perspective view of an example of a protruding plate, and Fig. 4 is an enlarged view of part IV in Fig. 2.

[0030] The wooden frame structure 100 is formed by a framework 90 including wooden columns 10 (one example of a framework member), wooden beams 20 (another example of a framework member and one example of a cross member) and a foundation 30 (another example of a framework member and another example of a cross member), and wooden panels 40 are arranged in a large-wall style on the framework 90. ​​Here, the illustrated example shows the framework 90 for the first floor of a building, but when the framework is for the upper floors of a building with two or more floors, the framework is formed by left and right columns and upper and lower beams. Also, in the illustrated example, the wooden panels 40 are arranged in a large-wall style on the columns 10, but they may be arranged in a large-wall style on the beams 20 and foundation 30 in addition to the columns 10, or the wooden panels 40 may be arranged in a solid wall style on the framework 90.

[0031] The dimensions of the rectangular frame 90 as viewed from the front vary, but the center distance B between the left and right columns 10 can be set, for example, in the range of about 0.5 m to 2.0 m, and can be set to 0.5 m, 0.75 m, 1.0 m, 1.5 m, 2.0 m, etc. Meanwhile, the floor height H can be set to about 2.5 m to 3 m.

[0032] Of the pair of pillars 10, a groove 12 is provided on the side surface 11 at the front side as viewed in Fig. 1. A protruding plate 50 shown in Figs. 2 to 4 is accommodated in each groove 12 of the pair of pillars 10, and an end portion 42 of a wood panel 40 is further accommodated therein, and the wood panel 40, the protruding plate 50, and the pillar 10 are joined together by fasteners 60 that are driven or screwed into the surface 41 of the wood panel 40. In other words, a joint 80 is formed in which the pillar 10 and the wood panel 40 are directly joined together via the protruding plate 50.

[0033] The fasteners 60 may be nails, screws, bolts (including lag screw bolts), etc. On the other hand, structural plywood, laminated lumber, CLT panels, etc. may be used for the wooden panels 40. Among them, CLT panels are preferable because they can be used in a wide range of panels with dimensions of up to 12 m x 2.6 m, and they can reduce the number of connection points between panels on-site as much as possible, which leads to improved strength and ease of construction of the wooden frame structure 100.

[0034] The wooden panel 40, the beam 20, and the base 30 are joined to each other via a tenon pipe 65. The tenon pipe 65 has a pin hole (not shown), and a pin 66 such as a drift pin is inserted into the pin hole, thereby joining the tenon pipe 65 to the beam 20 and the base 30, and fixing the beam 20 and the base 30 to the upper surface 43 and the lower surface 44 of the wooden panel 40.

[0035] In the illustrated example, two tenon pipes 65 are provided on each of the upper surface 43 and the lower surface 44 of the wood panel 40, but the number of tenon pipes 65 is not limited to that shown in the figure.

[0036] As shown in the illustrated example, by joining the upper and lower surfaces of the wood panel 40 to the beam 20 and the foundation 30 with tenon pipes 65, it is preferable that the shear force S acting on the interface between the wood panel 40 and the beam 20, etc. when the frame 90 is deformed during an earthquake can be borne by the tenon pipes 65.

[0037] Furthermore, if the design concept is such that shear forces will not be borne at the interfaces between the upper and lower surfaces of the wood panel 40 and the beams 20 or foundation 30, the tenon pipes 65 are not necessary, and the wood panel 40 may be joined only to the left and right columns 10.

[0038] Notches 45 are provided at the four corners of the wood panel 40. These notches 45 at the corners prevent the corners of the wood panel 40 from coming into contact with the left and right columns 10, beams 20, and foundations 30 and pushing against each other, resulting in a compressive force that would increase the ultimate strength when a horizontal force F acts on the wooden frame structure 100 during an earthquake and causes deformation. Here, if there is no risk of an increase in the ultimate strength at the corners of the wood panel 40, the notches 45 at the corners are not necessary.

[0039] As shown in Figures 2 and 3, a protrusion plate 50 is housed in a groove 12 provided in one side surface 11 of a column 10. As shown in Figure 3, the protrusion plate 50 has a plurality of protrusions 53 formed by scraping up a plurality of notches 52 in a steel plate 51 on both of a pair of wide surfaces 51a of the plate 51. In Figure 3, where the protrusions 53 are shown by dotted lines, the protrusions 53 are scraped up on the opposite wide surface 51a side.

[0040] As shown in Figure 4, the protruding plate 50 is placed in the groove 12 of the pillar 10, and then the end 42 of the wood panel 40 is placed therein. Then, a fastener 60 is attached to the surface 41 of the wood panel 40, so that the multiple protrusions 53 of the protruding plate 50 penetrate both the pillar 10 and the wood panel 40, and the pillar 10 and the wood panel 40 are joined by the fastener 60 and the protruding plate 50, forming a joint 80.

[0041] Here, one long protrusion plate 50 may be arranged over the entire area of ​​the vertically extending groove 12 shown in Figure 1, or multiple short protrusion plates 50 may be arranged continuously or intermittently in the groove 12.

[0042] In the example shown in Figures 2 and 4, the protruding plate 50 and the end 42 of the wood panel 40 are accommodated in the groove 12 of the column 10, so that the side 11 of the column 10 and the surface 41 of the wood panel 40 are flush with each other, and the surfaces of the column 10 and the wood panel 40 are continuous, contributing to the formation of a wooden frame structure 100 with excellent external design.

[0043] 2 and 4, the protrusions 53 of the protruding plate 50 penetrate the structural members, the column 10 and the wooden panel 40, and the sliding rigidity at the interface between them is increased, thereby increasing the rigidity of the joint 80 while reducing the number of fasteners 60, and reducing the number of fasteners 60 makes it possible to suppress an increase in the ultimate strength of the joint 80. Furthermore, since the number of fasteners 60 can be reduced as much as possible, the workability of the wooden frame structure 100 is improved.

[0044] In addition, with the protruding plate 50 of the illustrated example, a structure can be formed in which a single steel plate 51 penetrates both the pillar 10 and the wood panel 40 simply by cutting out and scraping it up, which is preferable because it makes it possible to form a joint 80 between the pillar 10 and the wood panel 40 that is highly rigid and has a suppressed increase in ultimate strength at the lowest possible manufacturing cost.

[0045] Here, the projection plate may have a configuration in which a plurality of projections are joined to a steel plate by welding or the like, in addition to the configuration shown in the drawings.

[0046] The load-displacement relationship between a column and a wooden panel for both a conventional joint and the illustrated joint 80 will be described below with reference to Figures 5A and 5B. Figure 5A is a diagram simulating the load-displacement curve of a joint using only conventional fasteners, and Figure 5B is a diagram simulating the load-displacement curve of a joint using fasteners and a protruding plate that constitute a wooden frame structure according to the embodiment.

[0047] As shown in FIG. 5A, in a conventional joint between a pillar 10 and a wood panel 40 formed only with a large number of fasteners, the load tends to increase even after exceeding the yield load Py due to the use of a large number of thin-diameter fasteners, which leads to an increase in the ultimate strength.

[0048] In contrast, as shown in Figure 5B, in a joint with a projection plate 50, the load-displacement relationship of the projection plate shows a tendency for the strength to drop sharply after exceeding the yield load Py', and the load-displacement relationship of the fasteners shows a suppressed increase in load compared to Figure 5A due to the small number of fasteners, and the combined load-displacement curve shows a tendency for the increase in load after the yield load Py to be suppressed. As a result, the increase in ultimate strength in the joint is suppressed, and suppressing the increase in ultimate strength leads to suppressing pre-destruction of the joint.

[0049] Here, the yield shear strength Py of the joint 80 between the column 10 and the wooden panel 40 in the wooden frame structure 100 when a horizontal force F acts during an earthquake can be expressed by the following formula (1).

[0050]

number

[0051] In equation (1), if the length of the protruding plate is proportional to the story height H of the frame, Qy can be expressed by the following equation (2).

[0052]

number

[0053] By substituting equation (2) into equation (1), we obtain the following equation (3).

[0054]

number

[0055] As is clear from equation (3), the yield shear strength Py is determined only by the distance between the columns, regardless of the floor height H, which simplifies the design method.

[0056] Fig. 6 is a diagram showing an example of a structural model of the wooden frame structure 100 shown in Fig. 1. In the structural model M, the joints (joints) of the columns C to the beams B1 and foundations B2 include joints such as tenons, mortise joints, and dovetail joints, as well as joints using metal fittings such as tenon pipes, but in any case, they are represented by pins P1 in the structural model.

[0057] On the other hand, the connections between the left and right columns C and the wooden panel W using multiple fasteners (nails, screws, etc.) and a protruding plate can be modeled using springs Sp, and the connections between the beams B1 and base B2 and the wooden panel W using tenon pipes are structurally represented as pins P2.

[0058] In the wooden frame structure 100 shown in Figure 1, the pillar 10 and the wooden panel 40 are joined by a protruding plate 50 and a minimum number of fasteners 60, thereby forming a joint 80 that is highly rigid and has a reduced increase in ultimate strength.

[0059] Next, another example of the joint will be described with reference to Figures 7A to 7C, where Figure 7A is a horizontal cross-sectional view showing another example of the joint, and Figures 7B and 7C are vertical cross-sectional views showing still another example of the joint.

[0060] The example shown in FIG. 7A is a solid wall type joint 80A in which ends of two wooden panels 40 abut on both ends of one side surface 11 of a pillar 10, respectively.

[0061] At the joint 80A, a support member 70 made of a square timber smaller than the pillar 10 is disposed to the side of the side surface 11 of the pillar 10 via a protruding plate 50, and these components are joined together by a fastener 60 that penetrates the support member 70 and the protruding plate 50 to reach the pillar 10. This joining causes the multiple protrusions 53 of the protruding plate 50 to pierce both the support member 70 and the pillar 10.

[0062] Separate protruding plates 50 are then placed on the opposing sides of the receiving material 70, and the wood panel 40 is placed on the outside of these, and these components are joined together with fasteners 60 that penetrate the wood panel 40 and the protruding plate 50 to reach the receiving material 70. This joining causes the multiple protrusions 53 of the protruding plate 50 to pierce both the receiving material 70 and the wood panel 40.

[0063] In this way, the joint 80A is a joint in which the pillar 10 and the wood panel 40 are indirectly joined via the receiving material 70. In the joint 80A as well, by interposing the protruding plate 50 between each member, the number of fasteners 60 can be reduced while the rigidity of the joint 80A can be increased, and by reducing the number of fasteners 60, an increase in the ultimate strength of the joint 80A can be suppressed.

[0064] Here, unlike the illustrated example, a single wooden panel 40 may be joined to the pillar 10 via a receiving material 70.

[0065] On the other hand, while both the examples shown in Figures 7B and 7C show the joint between the base 30 and the wood panel 40, the example shown in Figure 7B is a solid wall type joint, and the example shown in Figure 7C is a large wall type joint.

[0066] 7B, a receiving material 70 made of a square timber smaller than the base 30 is disposed above the upper surface 31 of the base 30 via a protruding plate 50, and these components are joined together by a fastener 60 that penetrates the receiving material 70 and the protruding plate 50 to reach the base 30. With this joining, the multiple protrusions 53 of the protruding plate 50 pierce both the receiving material 70 and the base 30.

[0067] A separate protruding plate 50 is then abutted against the side of the receiving material 70, and the wood panel 40 is placed on the outside of that, and these components are joined together with fasteners 60 that penetrate the wood panel 40 and the protruding plate 50 and reach the receiving material 70. This joining causes the multiple protrusions 53 of the protruding plate 50 to pierce both the receiving material 70 and the wood panel 40.

[0068] In this way, the joint 80B is a joint where the base 30 and the wood panel 40 are indirectly joined via the receiving material 70. In the joint 80B as well, by interposing the protruding plate 50 between each member, the number of fasteners 60 can be reduced while the rigidity of the joint 80B can be increased, and by reducing the number of fasteners 60, an increase in the ultimate strength of the joint 80B can be suppressed.

[0069] 7C, the lower end of the wood panel 40 is placed on the side surface 32 of the base 30 via the protruding plate 50, and these components are joined with fasteners 60 that penetrate the wood panel 40 and the protruding plate 50 to reach the base 30. With this joining, the multiple protrusions 53 of the protruding plate 50 pierce both the wood panel 40 and the base 30.

[0070] In this way, the joint 80C is a joint where the base 30 and the wood panel 40 are directly joined. By interposing the protruding plate 50 between each member in the joint 80C, the number of fasteners 60 can be reduced while still increasing the rigidity of the joint 80C, and by reducing the number of fasteners 60, an increase in the ultimate strength of the joint 80C can be suppressed.

[0071] In addition, the present invention is not limited to the configuration shown here, and may be implemented in other embodiments in which other components are combined with the configurations and the like of the above-mentioned embodiment. In this regard, the present invention may be modified within the scope of the gist of the present invention, and may be appropriately determined according to the application form.
