[0003] [Patent Document 1] Japanese Patent Application Publication No. 04-258428 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in connecting frame members of a building, there are cases where the end faces of the frame members are not used. In such cases, there is room for improvement in the connection structure of the frame members. [Means for solving the problem]

[0005] (1) A building that solves the above problem is a building comprising a first frame member, a second frame member connected to the first frame member, and a connecting member connecting the first frame member and the second frame member, wherein the connecting member has a fixing portion fixed to a side of the first frame member and a support portion extending from the fixing portion to support the second frame member, wherein the support portion has a temporary placement portion on which the second frame member is temporarily placed and a first through hole through which a fastening member passes, wherein the second frame member comprises a frame member main body and a connecting portion provided on a side of the frame member main body and connected to the support portion, wherein the connecting portion has a connecting main body portion, an engaging portion provided on the connecting main body portion and engaging with the temporary placement portion, and a second through hole provided on the connecting main body portion through which the fastening member passes, and wherein the connecting portion is connected to the support portion by the fastening member passing through the first through hole and the second through hole with the engaging portion engaged with the temporary placement portion. According to this configuration, the second frame member can be temporarily placed on the first frame member at a portion where the side portion of the frame member main body of the second frame member and the connecting member are joined.

[0006] (2) In the building of (1) above, the engagement portion has a protrusion extending obliquely downward from the connecting body portion, and the temporary placement portion has an insertion portion through which the protrusion is inserted. With this configuration, the protrusion extending downward is caught in the insertion portion, thereby stabilizing the temporary placement state.

[0007] (3) In the building of (2) above, the protrusion is formed of a member separate from the connecting body, or is integral with the connecting body. With this configuration, the protrusion can be formed of a member separate from the connecting body, or the connecting body and the protrusion can be formed integrally.

[0008] (4) In the building described in (2) or (3) above, the protruding portion is provided with a claw portion that prevents the protruding portion from coming out of the insertion portion. According to this configuration, the claw portion is caught in the insertion portion, so that the second frame member can be prevented from falling.

[0009] (5) In the building of (1) above, the engaging portion has an engaging through hole provided in the connecting body portion, and the temporary placement portion has an engaging protrusion portion extending obliquely upward from the support portion and inserted into the engaging through hole. With this configuration, the engaging through hole of the connecting body portion is caught on the protrusion portion extending upward from the support portion, so that the temporary placement state can be stabilized.

[0010] (6) In the building of (1) above, the temporary placement portion includes a first temporary placement portion provided on an upper end of the support portion, and the engagement portion is configured as a hook that is hung on the first temporary placement portion. With this configuration, since there is no need to insert the protruding portion into the insertion portion, the second frame member can be easily temporarily placed on the support portion.

[0011] (7) In the building of (6) above, the support part is configured to extend obliquely downward from the fixed part, and the temporary placement part of the support part has the first temporary placement part and a second temporary placement part that stops the second frame member from moving obliquely downward. With this configuration, it is possible to prevent the second frame member from sliding down.

[0012] (8) In the building of any one of (1) to (7) above, the second through hole of the second frame member is configured to overlap with the first through hole of the connecting member when the engagement portion of the second frame member is engaged with the temporary placement portion of the connecting member. This configuration reduces the effort required to adjust the position of the second through hole relative to the first through hole. Effect of the Invention

[0013] According to the building disclosed herein, construction is easy because it has a structure that allows the second frame member to be temporarily placed on the first frame member. [Brief description of the drawings]

[0015] First Embodiment The building 1 will be described with reference to Figures 1 to 8. Examples of the building 1 include a detached house, an apartment building, and a public facility. As shown in FIG. 1, the building 1 includes a first frame member 10, a second frame member 20 connected to the first frame member 10, and a connecting member 30. The first frame member 10 and the second frame member 20 are members that constitute the framework of the building 1. The first frame member 10 is a member that is arranged horizontally or vertically in the building 1. Examples of the first frame member 10 include a column, a beam, a girder, and a ridgepole. The second frame member 20 is a member that is connected to the first frame member 10. In one example, the second frame member 20 is connected to the first frame member 10 so as to cross horizontally. In another example, the second frame member 20 is connected to the first frame member 10 so as to cross diagonally. Examples of the second frame member 20 include a beam, a girder, a slope beam, a rafter, and an arm.

[0016] The building 1 shown in this embodiment comprises pillars 2 and a roof 3. The roof 3 comprises a first frame member 10 and a second frame member 20. The first frame member 10 constitutes a ridge beam 6. The second frame member 20 constitutes a slope beam 7.

[0017] 2, the second frame member 20 is connected to the first frame member 10 via a connecting member 30. Specifically, the upper end of the second frame member 20 is connected to the first frame member 10 via the connecting member 30. The lower end of the second frame member 20 is supported by a girder or beam.

[0018] In this embodiment, the entire portion where the end of the second frame member 20 is connected to the first frame member 10 via the connecting member 30 is referred to as the connection portion 5. The connection portion 5 includes a portion of the first frame member 10 where the connecting member 30 is provided, the connecting member 30, and a portion of the second frame member 20 connected to the connecting member 30.

[0019] <First frame member> The first frame member 10 is made of wood or metal. A second frame member 20 is connected to the first frame member 10. A connecting member 30 is fixed to a side surface 11 of the first frame member 10 (see FIG. 2). In one example, the first frame member 10 is made of wood having a rectangular cross section. The first frame member 10 may be a laminated timber.

[0020] <Second frame member> The second frame member 20 comprises a frame member main body 20A and a connecting portion 23 that is connected to the support portion 32 of the connecting member 30. The frame member main body 20A is made of wood or metal. The frame member main body 20A has a side portion 22. When the second frame member 20 is attached to the first frame member 10, the direction perpendicular to the longitudinal direction DL and the up-down direction DZ of the frame member main body 20A is defined as the lateral direction DH (see FIG. 2). The side portion 22 of the frame member main body 20A is defined as a portion that includes a surface that intersects with the lateral direction DH. An example of the frame member main body 20A is a lip channel steel. When the frame member main body 20A is a lip channel steel, the side portion 22 of the frame member main body 20A includes the lip portion 22X of the lip channel steel.

[0021] The connecting portion 23 is provided on the side portion 22 of the frame member main body 20A. The connecting portion 23 has a connecting main body portion 23A, an engagement portion 24 provided on the connecting main body portion 23A, and a second through hole 25. The second through hole 25 is provided in the connecting main body portion 23A so that a fastening member 40 can pass through. An example of the fastening member 40 is a hexagonal bolt 41.

[0022] The coupling body 23A is made of an iron plate. The coupling body 23A is attached to the side portion 22 of the frame member body 20A by welding, brazing, or fastening. For example, the coupling body 23A is joined to the lip portion 22X of the lip channel steel by welding or brazing.

[0023] 6, the second through hole 25 is configured to overlap with the first through hole 37 of the connecting member 30 in a state in which the engaging portion 24 of the second frame member 20 is engaged with the temporary placement portion 35 (see below) of the connecting member 30. Specifically, in the temporary placement state of the second frame member 20, with the lower portion of the engaging portion 24 in contact with the inner circumferential surface 39 of the insertion portion 36 of the connecting member 30, the second through hole 25 of the second frame member 20 overlaps with the first through hole 37 of the connecting member 30 in a side view.

[0024] 4, in one example, the coupling body portion 23A is provided with two second through holes 25. The two second through holes 25 are provided in the coupling body portion 23A such that the engagement portion 24 is located between the two second through holes 25.

[0025] The engaging portion 24 is configured to engage with the temporary placement portion 35 of the connecting member 30. Specifically, the engaging portion 24 has a protruding portion 26. The protruding portion 26 extends obliquely downward from the connecting main body portion 23A. An example of the protruding portion 26 is a steel pole 26A. The pole 26A is joined to the connecting main body portion 23A.

[0026] As shown in FIG. 7, the angle A between the center line C of the protrusion 26 and the reference plane SX is 10 degrees or more and 20 degrees or less. The reference plane SX is defined as a plane that is perpendicular to the side surface of the joint body 23A and extends parallel to the longitudinal direction DL of the frame member body 20A of the second frame member 20. In one example, the angle A is 15 degrees. The protrusion 26 may be integrally formed with the joint body 23A or may be formed by a separate member. In this embodiment, the protrusion 26 is formed by a separate member from the joint body 23A. When the joint body 23A is formed by an iron plate and the protrusion 26 is an iron pole, the protrusion 26 is attached to the joint body 23A by welding or brazing.

[0027] <Connecting parts> The connecting member 30 connects the first frame member 10 and the second frame member 20. The connecting member 30 is made of a steel material.

[0028] 3, the connecting member 30 has a fixing portion 31 fixed to the side surface 11 of the first frame member 10, and a support portion 32 extending from the fixing portion 31. The fixing portion 31 is fixed by a bolt passing through a fixing bolt hole 33. The support portion 32 extending from the fixing portion 31 is reinforced by a reinforcing portion 34 provided at its base.

[0029] The support portion 32 supports the second frame member 20. The support portion 32 has a temporary placement portion 35 and a first through hole 37 through which the fastening member 40 passes. The temporary placement portion 35 is configured to temporarily place the second frame member 20. Specifically, the temporary placement portion 35 has an insertion portion 36 through which the protrusion 26 passes. As an example, the insertion portion 36 is configured as a circular hole 36A. The diameter of the circular hole 36A is 5 mm or more larger than the diameter of the pole 26A.

[0030] The first through hole 37 is configured to extend along the extension direction of the support portion 32 (see FIG. 4). The first through hole 37 is provided so as to face the second through hole 25 in an engaged state in which the engaging portion 24 of the second frame member 20 is engaged with the temporary placement portion 35 of the connecting member 30. The engaged state indicates a state in which the connection main body portion 23A of the second frame member 20 is in contact with the support portion 32 and the engaging portion 24 of the second frame member 20 is inserted into the insertion portion 36 of the temporary placement portion 35. When two second through holes 25 are provided in the connection main body portion 23A, the first through holes 37 are provided in the support portion 32 so as to face each of them.

[0031] <Temporary placement and fastening method of second frame member> A method for temporarily placing the second frame member 20 on the connecting member 30 and a method for fastening the second frame member 20 and the connecting member 30 will be described.

[0032] As shown in FIG. 2, the second frame member 20 is arranged so that the joint portion 23 of the second frame member 20 is located near the support portion 32 of the connecting member 30 fixed to the first frame member 10.

[0033] 4, the second frame member 20 is brought closer to the first frame member 10 so that the protruding portion 26 of the second frame member 20 is inserted into the insertion portion 36. For example, the second frame member 20 is placed with respect to the support portion 32 of the connecting member 30 so that the line CX along the center line C of the protruding portion 26 passes through the center of the insertion portion 36. The second frame member 20 is then brought closer to the support portion 32 of the connecting member 30 so that the center line C of the protruding portion 26 does not deviate from the line CX, and the protruding portion 26 is inserted into the insertion portion 36.

[0034] 5, the protruding portion 26 of the second frame member 20 engages with the insertion portion 36. This causes the second frame member 20 to be temporarily placed on the connecting member 30. Next, the hexagonal bolt 41 is inserted from the second through hole 25 of the joining portion 23 toward the first through hole 37 of the support portion 32.

[0035] 8, the end 42 of the inserted hexagonal bolt 41 is tightened with a nut 43. As a result, the joining portion 23 is joined to the support portion 32 of the connecting member 30 by the fastening member 40 passing through the first through hole 37 and the second through hole 25, with the protruding portion 26 as the engaging portion 24 engaged with the insertion portion 36 of the temporary placement portion 35. In this manner, the second frame member 20 is joined to the first frame member 10.

[0036] The operation of this embodiment will now be described. The second frame member 20 is connected to the first frame member 10 via the connecting member 30. Specifically, the second frame member 20 is connected to the support portion 32 of the connecting member 30, which extends so that the side portion 22 of the second frame member 20 crosses the side surface 11 of the first frame member 10. However, when constructing the connection portion 5 of such a connection structure, if the second frame member 20 is not supported, it is difficult to align the side surface 11 of the first frame member 10 with the support portion 32 of the connecting member 30, and the connection work takes time. In particular, when the second frame member 20 is made of steel, the second frame member 20 is heavy, which places a large burden on the operator. For this reason, the connection work of the second frame member 20 may require multiple workers.

[0037] In this regard, in this embodiment, the side portion 22 of the second frame member 20 is provided with an engagement portion 24. The connecting member 30 is provided with a temporary placement portion 35 in which the second frame member 20 is temporarily placed. Specifically, the temporary placement portion 35 is configured so that the protrusion 26 of the engagement portion 24 is inserted. This allows the second frame member 20 to be temporarily placed on the connecting member 30. Therefore, the worker can temporarily place the second frame member 20 and then connect the connection portion 23 of the second frame member 20 to the support portion 32 of the connecting member 30. This reduces the burden on the worker. In addition, when the second frame member 20 is temporarily placed on the connecting member 30, the second through hole 25 of the connection portion 23 overlaps with the first through hole 37 of the support portion 32, so that the position adjustment work of the second frame member 20 is reduced. In this respect as well, the burden on the worker can be reduced.

[0038] The effects of this embodiment will be described. (1) The building 1 comprises a first frame member 10, a second frame member 20, and a connecting member 30. The second frame member 20 has a joining portion 23. The joining portion 23 of the second frame member 20 is joined to the support portion 32 by a fastening member 40, with the engagement portion 24 engaged with the temporary placement portion 35 of the connecting member 30. With this configuration, the second frame member 20 can be temporarily placed on the first frame member 10 at the portion where the side portion 22 of the second frame member 20 and the connecting member 30 are joined.

[0039] (2) The engaging portion 24 has a protruding portion 26 extending obliquely downward from the connecting body portion 23A. The temporary placement portion 35 has an insertion portion 36 through which the protruding portion 26 is inserted. With this configuration, the downwardly extending protruding portion 26 is caught in the insertion portion 36, so that the temporary placement state of the second frame member 20 can be stabilized.

[0040] (3) The protrusion 26 is formed of a member separate from the coupling main body 23A. The protrusion 26 may be formed integrally with the coupling main body 23A. With this configuration, the protrusion 26 can be formed of a member separate from the coupling main body 23A. Alternatively, the coupling main body 23A and the protrusion 26 can be formed integrally.

[0041] (4) The second through hole 25 of the second frame member 20 is configured to overlap with the first through hole 37 of the connecting member 30 in a state in which the protruding portion 26 of the second frame member 20 is engaged with the temporary placement portion 35 of the connecting member 30. According to this configuration, it is possible to reduce the effort required to adjust the position of the second through hole 25 relative to the first through hole 37.

[0042] <Second embodiment> The building 1 of this embodiment will be described with reference to Figures 9 to 11. In this embodiment, components common to the first embodiment are given the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0043] The structure of the connection part 5 of this embodiment differs from that of the connection part 5 of the first embodiment in the following points. In the first embodiment, the protrusion 26 of the coupling part 23 is formed by a pole 26A that is a separate member from the coupling main body 23A. In contrast, in this embodiment, the protrusion 26 of the coupling part 23 is formed integrally with the coupling main body 23A.

[0044] In one example, as shown in FIG. 9, the protrusion 26 is configured as a bent portion 26B of a portion of the coupling body 23A. The bent portion 26B extends obliquely downward from the coupling body 23A. The bent portion 26B is formed by bending a portion of the coupling body 23A with a press. The angle between the center line of the bent portion 26B and the reference plane SX is 10 degrees or more and 20 degrees or less. In one example, the angle is 15 degrees. The reference plane SX is defined in the same manner as the reference plane SX of the first embodiment.

[0045] The insertion portion 36 of the connecting member 30 is configured so that the bent portion 26B can be inserted therethrough. The insertion portion 36 is configured as a rectangular hole 36B. The vertical length of the hole 36B is 5 mm or more greater than the vertical width of the bent portion 26B.

[0046] 10, the second frame member 20 is temporarily placed on the connecting member 30 by inserting the bent portion 26B into the hole 36B. The bent portion 26B engages with the hole 36B. In the temporarily placed state of the second frame member 20, the hole 36B of the connecting member 30 receives a load from the bent portion 26B.

[0047] 11, in the temporarily placed state of the second frame member 20, the second through hole 25 of the second frame member 20 overlaps with the first through hole 37 of the connecting member 30. Specifically, in the temporarily placed state of the second frame member 20, with the bottom surface of the bent portion 26B in contact with the hole 36B of the connecting member 30, the second through hole 25 of the second frame member 20 overlaps with the first through hole 37 of the connecting member 30 in a side view.

[0048] The effects of this embodiment will be described. The protruding portion 26 of the connecting portion 23 is configured as a bent portion 26B. The bent portion 26B is configured integrally with the connecting body portion 23A. With this configuration, the bent portion 26B can be easily formed.

[0049] <Third embodiment> The building 1 of this embodiment will be described with reference to Figures 12 to 15. In this embodiment, components common to the first embodiment are given the same reference numerals as those in the first embodiment, and descriptions of overlapping components will be omitted.

[0050] As shown in FIG. 12, in this embodiment, the engagement portion 24 of the coupling portion 23 is configured as a hook 26C that is hung on the first temporary placement portion 36C. As an example, the hook 26C has a groove 27 along the coupling body portion 23A. The groove 27 is configured so that the support portion 32 of the connecting member 30 is inserted therethrough. The tip of the hook 26C hangs downward. The length of the tip of the hook 26C is set so as not to hinder the insertion of the fastening member 40. The temporary placement portion 35 of the connecting member 30 includes the first temporary placement portion 36C. The first temporary placement portion 36C is provided at the upper end portion of the support portion 32. The first temporary placement portion 36C is configured as a recess into which the hook 26C fits.

[0051] 13, the hook 26C is engaged with the first temporary placement portion 36C so that the support portion 32 fits into the groove 27 of the hook 26C. In this way, the second frame member 20 is temporarily placed on the connecting member 30.

[0052] 14, in the temporary placement state of the second frame member 20, the first temporary placement portion 36C receives a load from the hook 26C. In the temporary placement state of the second frame member 20, the second through hole 25 of the second frame member 20 overlaps with the first through hole 37 of the connecting member 30. Specifically, in the temporary placement state of the second frame member 20, with the groove 27 of the hook 26C in contact with the upper surface of the first temporary placement portion 36C of the connecting member 30, the second through hole 25 of the second frame member 20 overlaps with the first through hole 37 of the connecting member 30 in a side view.

[0053] 15 , a hexagonal bolt 41 is inserted from the second through hole 25 of the connecting portion 23 of the second frame member 20 toward the first through hole 37 of the support portion 32. Then, an end portion 42 of the inserted hexagonal bolt 41 is tightened with a nut 43. In this manner, the second frame member 20 is joined to the first frame member 10.

[0054] The effects of this embodiment will be described. The engaging portion 24 of the second frame member 20 is configured as a hook 26C that is hung on the first temporary placement portion 36C of the connecting member 30. With this configuration, since there is no need to insert the protruding portion 26 into the insertion portion 36, the second frame member 20 can be easily temporarily placed on the support portion 32.

[0055] <Modification> The above-described embodiments are examples of forms that the building 1 may take, and are not intended to limit the form. The building 1 may take forms different from those exemplified in the above-described embodiments. One example is a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. An example of a modified embodiment is shown below.

[0056] 16, the protruding portion 26 of the coupling portion 23 may have a claw portion 28. The claw portion 28 is configured to prevent the protruding portion 26 from coming off the insertion portion 36. Specifically, the claw portion 28 is provided at the tip of the protruding portion 26.

[0057] 17, in one example, a claw portion 28A is joined to the tip of a pole 26A. The claw portion 28A is provided so as to be able to engage with an edge portion of the insertion portion 36. Therefore, when the second frame member 20 is in a temporarily placed state, the second frame member 20 is prevented from falling.

[0058] 18, the protrusion 26 of the coupling portion 23 may have a bent portion 26B having a claw portion 28B. As one example, the claw portion 28B is formed by bending the tip of the bent portion 26B with a press machine.

[0059] 19, the claw portion 28B is configured to be able to engage with the edge of the rectangular hole 36B of the support portion 32. Therefore, when the second frame member 20 is in the temporarily placed state, the second frame member 20 is prevented from falling.

[0060] When the support part 32 is configured to extend obliquely downward from the fixed part 31, the temporary placement part 35 of the support part 32 may be configured as follows.

[0061] An example will be described with reference to Figs. 20 and 21. In the third embodiment, the first temporary placement portion 36C as the temporary placement portion 35 of the support portion 32 is configured as a recess provided at the upper end of the support portion 32. In contrast, in this modified example, the temporary placement portion 35 of the support portion 32 has the first temporary placement portion 36C and the second temporary placement portion 36D. The first temporary placement portion 36C is formed flat. The second temporary placement portion 36D is configured to stop the second frame member 20 from moving diagonally downward by receiving the connecting portion 23. Specifically, the second temporary placement portion 36D protrudes from the support portion 32 so as to contact the lower surface of the connecting main body portion 23A of the second frame member 20 in the temporary placement state of the second frame member 20. With this configuration, it is possible to prevent the second frame member 20 from sliding down.

[0062] In the first and second embodiments, the engaging portion 24 of the connecting portion 23 is configured as the protruding portion 26 from the connecting main body portion 23A, but the configuration of the engaging portion 24 is not limited to this.

[0063] As shown in Fig. 22, the engagement portion 24 may have an engagement through hole 29. The engagement through hole 29 is provided in the connection main body portion 23A. In this case, the temporary placement portion 35 of the connecting member 30 has an engagement protrusion 38. The engagement protrusion 38 is configured to extend obliquely upward from the support portion 32 and pass through the engagement through hole 29. As an example, the engagement protrusion 38 is configured as a steel rod 38A. Even with such a configuration, the same effects as those of the first embodiment are achieved.

[0064] In the first and second embodiments, the inner circumferential surface 39 of the insertion portion 36 of the temporary placement portion 35 of the connecting member 30 may be configured as follows.

[0065] An example will be described with reference to Figures 23 and 24. The protruding portion 26 is configured as a pole 26A. The insertion portion 36 is configured as a circular hole 36A. The inner circumferential surface 39 of the circular hole 36A is inclined so as to follow the circumferential surface of the pole 26A when the second frame member 20 is in a temporarily placed state. With this configuration, the contact area between the pole 26A and the inner circumferential surface 39 of the hole 36A can be increased, making it difficult for the pole 26A to come out of the circular hole 36A.

[0066] As shown in FIG. 25, the frame member body 20A of the second frame member 20 may be an H-shaped steel. In one example, the frame member body 20A as an H-shaped steel is temporarily placed on the connecting member 30 so that both flanges are arranged one above the other. In such a case, the side portion 22 of the frame member body 20A includes the end surface 22Y of the flange. The connecting body portion 23A of the connecting portion 23 is configured as a plate. The connecting body portion 23A of the connecting portion 23 is joined to the end surface 22Y of the flange by welding or brazing.

[0067] As shown in FIG. 26, the frame member body 20A of the second frame member 20 may be a T-shaped steel. In one example, the frame member body 20A as a T-shaped steel is temporarily placed on the connecting member 30 so that the flange is placed on top. In such a case, the side portion 22 of the frame member body 20A includes the end face 22Z of the flange and the side face of the web 22W. The connecting body portion 23A of the connecting portion 23 is made of an L-shaped iron material. The connecting body portion 23A of the connecting portion 23 is joined to the end face 22Z of the flange and the web 22W by welding or brazing.

[0068] In this embodiment, the technology disclosed herein is applied to the connection 5 between the purlin 6 and the slope beam 7, but it can be applied to other connection parts 5.

[0069] 27, the technology of the present disclosure can also be applied to a connection structure between a pillar 2 and a beam 8. Here, a first frame member 10 constitutes the pillar 2. A second frame member 20 constitutes the beam 8. A connecting member 30 is attached to the side of the pillar 2, which is the first frame member 10. In this case, the support portion 32 extends perpendicular to the fixing portion 31.
