Description

  The present invention relates to a joining structure between a column member and a beam member used in a wooden building and a joining method thereof.

  In the conventional wooden frame structure, a structure that ensures seismic strength by the rigidity of the wall that uses bracing as a reinforcing material has been widely adopted. For this reason, a wall structure capable of ensuring the seismic strength is required, which causes a problem of restricting the degree of freedom in floor plan, the position of the window, the size of the opening area, and the like. In addition, the use of the braces is not only costly for the braces and fixing brackets, but also requires a lot of work for the attachment work, and the work cost is high. Furthermore, the fact that the wing plate bolt used as a means for joining the column member and the beam member cannot be expected to have a great reinforcing effect in terms of strength.

Therefore, in view of the above-mentioned problems, the present applicant has developed a joining method between a column member and a beam member having a large holding force in a joined state, and reduces the dependence on seismic strength based on the rigidity of a conventional wall, There has already been proposed a technique aimed at reducing restrictions on the degree of freedom of floor plan, the position of a window, the size of an opening area, etc. (Patent Document 1).
JP 2001-115552 A

  In the beam-column joining method described in Patent Document 1, upper and lower beam-side joint members and column-side joint members connected to the beam material and the column material are formed in a rack, and By connecting and fixing each other by rack connection, beams and pillars are joined, and it has many advantages such as a stronger joined state compared to conventional battledore bolts. Met.

  However, in this joining method, the beam-side lower joint member is placed on the column-side lower joint member, and the beam material is supported by the column material. Therefore, an upper through hole having a large insertion work space has to be provided in the upper part of the column member. This took time and effort to make a large hole in the column material, and also caused a decrease in the cross-sectional strength of the column material. Furthermore, in order to fix the column-side upper joint member to the column member, another member such as a wedge for pressing to fill the insertion work space is required, which is a factor in increasing the material cost.

  In addition, the relative positional relationship between the column member and the beam member is determined by the meshing between the racks formed on each joint member, etc. The column-side upper joint member must be inserted into the upper through-hole and simultaneously coupled to the beam-side upper joint member rack, which is very difficult. Furthermore, since the positional relationship of each joint member is determined by directly joining the joint members provided on the beam and column members, the joint members should be slightly engaged or eccentrically engaged. In such a case, there is a risk that the beam material or the like may fall down, which is very dangerous.

  The present invention has been made in view of the problems of these conventional techniques, and without easily providing a through hole having a large insertion work space in the column member, the column side joint member and the beam side joint member can be easily connected, It is an object of the present invention to provide a column beam connection structure of a wooden building and a method of bonding the same, which can reliably and safely determine the relative positional relationship between the beam member and the column member of the bonding member.

  In order to solve the above-mentioned problem, in the invention of claim 1, a beam-side upper connection fitting and a beam-side lower connection fitting respectively installed along the notches formed above and below the small edge portion of the beam material, and these beam-side upper portions By connecting the column-side upper connection fitting and the column-side lower connection fitting projecting at the joining position of the column fitting corresponding to the connection fitting and the beam-side lower connection fitting, respectively, A beam-to-column connection structure of a wooden building to which a column member is bonded, wherein at least one of the beam-side upper connection fitting and the column-side upper connection fitting is inclined in the longitudinal direction of the beam member and toward the bonding member Each connecting member is formed by joining a connecting bracket having an inclined surface substantially inclined to the inclined surface across the beam-side upper connecting bracket and the column-side upper connecting bracket so as to press-contact the inclined surfaces. Adopted technical means of joining

  According to the present invention, as described above, the beam-side upper connection fitting and the column-side upper connection fitting respectively installed on the beam member and the column member of the joining member are configured to be coupled via the connection fitting. The column-side upper connection fitting does not need to be attached to the column material and combined with the beam-side upper connection fitting at the same time. For this reason, the connection work of each upper connection metal fitting can be performed easily. In addition, the connecting metal fitting has an inclined surface having a substantially opposite inclination to the longitudinal direction of the beam material provided on at least one of the column-side upper connecting fitting and the beam-side upper connecting fitting and the inclined surface inclined to the column side or the beam side. Is provided. And since the connecting metal fittings are coupled across the upper connection metal fittings so that the inclined surfaces are in pressure contact with each other, the positional relationship of each joining member is the connection metal fittings provided on the column material and the beam material. It is determined by the connection via the connecting metal fittings, not by the mutual connection. As a result, the connection work can be performed while confirming the engagement state between the metal fittings, so that the beam material and the column material can be reliably and safely joined, and the workability is greatly improved.

  In the invention of claim 2, the beam-side upper connection fitting and the beam-side lower connection fitting are respectively installed along the notch portions formed above and below the small edge portion of the beam material, and corresponding to the beam-side lower connection fitting. The column-side lower connection fitting protrudes from the column joint to the beam, and the beam-side lower connection fitting is placed on the column-side lower connection fitting to support the beam. The beam side provided with a column-side upper connection fitting projecting at a position where the column corresponding to the connection fitting is joined to the beam member, and at least one of which has an inclined surface inclined in the longitudinal direction of the beam member and the joining member side By connecting the upper connecting bracket and the column-side upper connecting bracket across the connecting bracket having an inclined surface substantially opposite to the inclined surface, the beam-side upper connecting bracket and the beam-side upper connecting bracket are in contact with each other. Connect the column-side upper connection fitting to join the beam of the joining member and the column. That method was adopted. According to the present invention, even after the beam-side lower connection fitting is placed on the column-side lower connection fitting and the beam member is supported by the column member, the column-side upper connection fitting only protrudes from the column member. There is no need to insert and fix the pillar material. As a result, the column member can be connected to the beam-side upper connection fitting without providing an upper through-hole having a large work space that reduces the cross-sectional strength of the column member. Therefore, it becomes possible to join the column member and the beam member in a predetermined positional relationship. Furthermore, the labor of making a large hole in the column material can be saved, and a separate member such as a press wedge is not required to fill the hole, so that the operation cost can be reduced.

  According to the column beam connection structure and the column beam connection method in the wooden building of the present invention, the beam side upper connection fitting and the column side upper connection fitting respectively installed on the beam member and the column member are coupled via the connection fitting. Therefore, each joining member can be joined easily. In addition, after the beam-side lower connection fitting was placed on the column-side lower connection fitting and the beam member was supported by the column member, the column-side upper connection fitting protruded at the joint position of the column member with the beam member. In addition, there is no need to provide an upper through-hole having a large work space that lowers the cross-sectional strength in the column material, and it is possible to reduce material costs and work costs. Furthermore, an inclined surface that is inclined in the longitudinal direction of the beam member provided on at least one of the beam-side upper connection fitting and the column-side upper connection fitting and on the joining member side thereof, and a substantially reverse gradient on the inclined surface provided in the connection fitting. Since the connecting brackets are joined across the upper connecting brackets so that they are in pressure contact with each other, the relative positional relationship between the beam material and the column member is determined between the brackets during the connection work. It is possible to make a reliable and safe decision while confirming the engagement state, and as a result, the efficiency of the connection work is greatly improved.

  The pillar or beam of a wooden building to which the present invention is applied further reduces the dependence on the seismic strength based on the rigidity of the wall, so that the degree of freedom in layout, the position of the window, the size of the opening area, etc. Although it is desirable to use a structural laminated material because the constraints can be greatly reduced, it goes without saying that general wood processed into a predetermined size can also be applied. As for the laminated material, a fiber reinforced laminated material in which reinforcing fibers such as carbon fibers and aramid fibers are sandwiched between the laminated portions at the time of bonding is extremely effective in terms of strength. In addition, as a specific form of joining between the column member and the beam member, various forms such as a cross shape, a T shape, an L shape, or a linear shape are possible with the column material as a center. In addition, various means can be used to press the inclined surfaces of the upper connection fittings and the connection fittings together, such as those using the weight of the connection fittings themselves, or those that use the pushing force of a human power or a tool such as a hammer. Although it is possible, especially when the inclined surfaces are pressed against each other by using a tightening force such as a bolt, the position of the column and the beam can be finely adjusted. This is also preferable because it leads to prevention. In addition, if an anchor member is embedded in advance at the joining position of the column material to the beam material, the beam side lower connection fitting is placed on the column side lower connection fitting and the beam material is supported by the column material. However, since the column-side upper connection fitting can be easily provided on the column member, the workability is further improved. Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a cross-sectional view of a beam-column joint portion showing an embodiment of the present invention, and shows a state in which beam materials are joined to the left and right with a column material as a center. As shown in the figure, the present invention is applied to a case where a beam material G is joined to a column material C. An upper notch 6 and a lower notch are provided at the upper and lower portions of the fore portion of each beam material G, respectively. A portion 7 is formed, and the beam-side connection fittings 2 and 5 are installed along the notches 6 and 7. The beam-side lower connection fitting 5 is directly connected to the column-side connection fitting 4, and the beam-side upper connection fitting 2 is connected to the column-side connection fitting 1 protruding from the column member C via the connection fitting 3. Thus, the column material C and the beam material G are joined. Further, the beam-side upper connection fitting 2 installed in the upper notch 6 of the beam material G is formed with an inclined surface 2c that is inclined in the longitudinal direction of the beam material G and toward the beam material side. The connecting metal fitting 3 having the inclined surface with the reverse gradient is engaged with the column-side upper connecting fitting 1 while being engaged with the beam-side upper connecting fitting 2 while pressing the inclined surfaces. The upper and lower column-side connection fittings 1 and 4 and the beam-side connection fittings 2 and 5 are, for example, anchor members 8 made of deformed reinforcing bars or the like fixed to anchor holes 8a and 9a formed in the column material C and the beam material G, respectively. , 9 are provided to each joining member. Accordingly, even after the lower column-side connection fitting 4 and the beam-side connection fitting 5 are connected, the column-side upper connection fitting 1 can project from the column member C, so that the column member C has a large work space. There is no need to provide an upper through hole. As for the connection between the column-side lower connection fitting 4 and the beam-side lower connection fitting 5, as in this embodiment, a rack is formed on the engaging surface of the two fittings, and the two fittings are rack-coupled. In addition, for example, flat metal fittings may be superposed and fixed with bolts or the like, and the means is not particularly limited.

  Next, the column side upper connecting fitting 1, the beam side upper connecting fitting 2, and the connecting fitting 3 used in the embodiment will be described. 2 and 3 are a plan view and a cross-sectional view, respectively, of the column-side upper connection fitting 1, and a schematic plan view with a small end surface 1 a and a large end surface 1 b perpendicular to the axial direction at the end portions, respectively. The trapezoidal column-side upper connection fitting 1 has a through hole 1c in which a bolt or the like can be stored. Then, when the column-side upper connection fitting 1 is attached with the small end surface side facing the column material, a bolt or the like is inserted from the large end surface side into the through-hole 1c and screwed with an anchor member fixed to the column material. Since the entire bolt is housed in the through hole 1 c of the column-side upper connection fitting 1, the bolt head or the like does not hinder the engagement between the connection fitting 3 and the column-side upper connection fitting 1. 4 and 5 are a plan view and a cross-sectional view of the beam-side upper connection fitting 2, respectively. The connection fitting 3 is connected to one end of the beam-side upper connection fitting 2 having a rectangular shape in plan view. A threaded portion 2b that is screwed with an anchor member fixed to the beam member is formed inside the other end side, and further, the recessed portion 2a is perpendicular to the axial direction. All the surfaces are inclined surfaces 2c inclined toward one end side. Further, as shown in the plan view of FIG. 6 and the front view of FIG. 7, the connection fitting 3 is an engagement recess 3 a that can engage the recess 2 a of the column-side upper connection fitting 1 and the beam-side upper connection fitting 2. Engaging projections 3b are provided at the end portions, and all of the engaging projections 3b are perpendicular to the axial direction so as to be in pressure contact with the inclined surface 2c of the beam-side upper connection fitting 2. The surface is formed on an inclined surface 3c having a substantially reverse gradient to the inclined surface 2c. In the present embodiment, the inclined surfaces that engage with each other are formed on the beam-side upper connection fitting 2 and the connection fitting 3, but they engage with each other between the column-side upper connection fitting 1 and the connection fitting 3. A similar inclined surface may be formed on the surface. In addition, the shape of the convex part and the concave part to which the above-mentioned three metal fittings illustrated respectively are engaged has a substantially trapezoidal shape in plan view, but is not particularly limited to this form, such as a square shape or a circular shape, Any shape that can be engaged with each other can be used. Further, in the engaging portion, side surfaces parallel to the axial direction are formed in a tapered shape from one side to the other side. This is for facilitating the engagement between the metal fittings. In particular, it may not be formed.

  Next, an example of the anchor member fixed to the column material will be described. The anchor member 8 used in the present invention is made of a deformed steel bar having a node on the outer peripheral surface as shown in the partial cross-sectional view of FIG. 8, for example, and screw portions (see FIG. (Not shown) and a bolt insertion hole 8b penetrating the peripheral wall is provided at the center thereof. In the case of a T-shaped or cross-shaped configuration, a deformed steel bar having a predetermined length is attached to the bolt insertion hole 8b via a relay bolt 8c. The bolt insertion hole 8b may have an inner peripheral surface formed in a screw shape. The anchor member 8 has a through-hole 8a drilled with a minimum size at a position where the column member C is joined to the beam member G, and the end surface of the anchor member 8 is substantially flush with the side surface of the column member C. Then, the anchor member 8 is fixed to the pillar material C by inserting the hole 8a as appropriate, and then filling the hole 8a with an adhesive such as an epoxy resin. If the beam is not joined to the side of the pillar, a screw or the like is previously embedded in the screw exposed on the side of the pillar, or the screw is covered with a wooden board with a hole in the center and fixed with bolts. You may take measures such as. Further, in the present invention, an example in which the anchor member is used in common is presented. For example, an anchor member made of a steel plate is fixed to a column member, and the column-side fitting is connected to the steel plate and the bolt. Needless to say, the invention is not limited to the above-described form, such as protruding by bonding.

  Next, in FIG. 9 and FIG. 10, a method of joining the column member and the beam member according to the above embodiment will be described. First, as shown in FIG. 9, among the upper and lower anchor members 8 fixed at the joining position of the column member C to the beam member G, the column-side lower connection fitting 4 is previously attached to the lower anchor member 8 on the rack surface. Make sure that is facing up. Then, the beam member G in which the beam side upper connection fitting 2 and the beam side lower connection fitting 5 are installed along the notches 6 and 7 on the column side lower connection fitting 4 is attached to the rack of the column side lower connection fitting 4. And the rack formed on the beam-side lower connection fitting 5 are engaged with each other so that the beam material G is supported by the column material C. At this time, if the lower connection fittings 4 and 5 are temporarily tightened with bolts 10 or the like, the beam member G is temporarily fixed to the column member C, so that the subsequent connecting operation becomes safe. Then, as shown in FIG. 10, after the column-side upper connecting fitting 1 protrudes from the upper anchor member 8 via a bolt, the connecting fitting 3 is connected to the column-side upper connecting fitting 1 and the beam-side upper connecting fitting 2. The metal fittings are combined by pushing them so as to straddle, and the bolts 10 where the lower connection metal fittings are temporarily fastened are properly tightened, or blindfolded members or the like are formed in the notches 6 and 7 formed in the small edge portions of the beam material. To complete the main joining work. In addition, when the connection fitting 3 is pushed between the upper connection fittings to be coupled, an inclined surface 2c inclined in the longitudinal direction of the beam member G included in the beam side upper connection fitting 2 and the beam member side, and a connection fitting The inclined surface 3c having a substantially reverse slope is pressed against the inclined surface provided, and the force to be pressed changes to a force that draws the beam G toward the column member via the inclined surfaces 2c and 3c inclined to the beam member. . As a result, at the same time when the connecting fitting 3 is engaged, the beam material G is drawn and the relative positional relationship with the column material C is determined. By the way, when pushing out the beam material G against the column material C or when pulling the column material C toward the beam material side, use the metal fittings with the inclined surfaces 2c and 3c inclined toward the column material side, respectively. The upper connection fittings 1 and 2 and the connection fitting 3 can be easily replaced. In this embodiment, the beam-side upper connection fitting 2 and the connection fitting 3 are provided with inclined surfaces 2c and 3c, respectively. However, the column-side upper connection fitting 1 and the connection fitting 3 are provided with the same inclined surfaces. Needless to say, the same effect as described above can be obtained.

  FIG. 11 is a cross-sectional view of a beam-to-column joint showing another embodiment of the present invention. The first embodiment is different from the column-side upper connection fitting 11, the beam-side upper connection fitting 12, and the connection fitting 13. Since only the shape is different and the other configuration is the same as that of the first embodiment, detailed description of the overlapping parts will be omitted. This embodiment is characterized in that the column-side upper connection fitting 11, the beam-side upper connection fitting 12, and the connection fitting 13 are rack-coupled by a rack formed between these fittings. The column-side upper connection fitting 11 and the beam-side upper connection fitting 12 in which a rack having inclined surfaces 11a, 11b, 12a, 12b inclined in the longitudinal direction of the beam G and on the beam material side and the column material side are formed, The upper connection fittings 11, 12 and the connection fitting 13 are tightened by the tightening bolts 14 in a state where the connection fittings 13 formed with racks having inclined surfaces 13 a, 13 b having substantially reverse slopes on the inclined surfaces straddle each other. . Then, by this tightening force, the inclined surfaces are brought into pressure contact with each other and coupled between the racks, and the column material C and the beam material G are joined.

  Next, the column side upper connecting fitting 11, the beam side upper connecting fitting 12, and the connecting fitting 13 used in the second embodiment will be described. 12 and 13 are a plan view and a cross-sectional view of the column-side upper connection fitting 11, respectively, and FIG. 14 shows a cross-sectional view of the beam-side upper connection fitting 12. The column-side upper connection fitting 11 and the beam-side upper connection fitting 12 of the present embodiment are surfaces on which a rack having inclined surfaces 11 a, 11 b, 12 a, 12 b inclined in the axial direction and on one side and the other side is coupled to the connection fitting 13. Furthermore, the screw holes 11c and 12c into which the tightening bolts 14 to be tightened together with the connecting metal fitting 13 are screwed are provided at two positions in each of the upper connecting metal fittings. The column-side upper connection fitting 11 has a bolt through hole 11d provided on one end side in the center of the rack surface because the beam member G is supported by the column member C and then protrudes from the column member via a bolt. A recess 11e is provided in communication with. And by providing this recessed part 11e, a bolt can be penetrated to the bolt through-hole 11d and it can attach to the anchor member 15 without interfering with a rack. The beam-side upper connection fitting 12 is formed with a screw portion 12d that is screwed to the anchor member 16 fixed to the beam member G inside the other end side. FIGS. 15 and 16 show a plan view and a cross-sectional view of the connection fitting 13, respectively. The connection fitting 13 is connected to the column side upper connection fitting 11 and the beam side upper connection fitting 12. A rack provided with inclined surfaces 13a and 13b having a substantially reverse gradient to the inclined surfaces is formed so that the inclined surfaces can be pressed against each other. Furthermore, the connecting metal fitting 13 is inserted with a bolt through which the tightening bolt 14 is inserted at a position where the screw holes 11c and 12c provided in the upper connecting metal fittings 11 and 12 are substantially aligned with the shaft core when coupled. A hole 13c is provided, and this bolt insertion hole 13c absorbs misalignment of each joining member when the column-side upper connection fitting 11, the beam-side upper connection fitting 12 and the coupling fitting 13 are tightened. Are formed in an elliptical shape. Note that the number of meshes of the racks formed on the upper connection fittings 11 and 12 and the connection fitting 13 is not particularly limited, and can be coupled to each other as long as at least one is formed.

  Next, a method for joining the column member and the beam member according to the second embodiment will be described. In the same manner as described above, detailed description of the same parts as those in the first embodiment will be omitted. As shown in FIG. 17, after the beam member G is supported by the column member C, the column-side upper connection fitting 11 is attached to the anchor member 15 fixed to the column member C with the rack surface facing upward. Then, the connecting metal fitting 13 is placed so as to mesh with the racks of the column-side upper connecting fitting 11 and the beam-side upper connecting fitting 12 with the rack surface facing downward. After that, the tightening bolt 14 is screwed into the screw holes 11c and 12c formed in the column side upper connection fitting 11 and the beam side upper connection fitting 12 through the bolt insertion hole 13c provided in the connection fitting 13, and the fittings are connected to each other. By tightening, each connection fitting is coupled. Also in the present embodiment, the longitudinal direction of the beam member G included in each of the upper connection fittings 11 and 12 is obtained by fastening the connecting fitting 13, the column side upper connection fitting 11 and the beam side upper connection fitting 12 with the fastening bolts 14. In addition, the inclined surfaces 11 a, 11 b, 12 a, 12 b inclined to the column material side and the beam material side, and the inclined surfaces 13 a, 13 b having substantially opposite gradients are brought into pressure contact with the inclined surfaces provided in the connection fitting 13. And since these inclined surfaces are inclined to both the column material side and the beam material side, the relative positional relationship of each bonding member while the pressing force pushes and pulls each bonding member simultaneously through the inclined surface. Will be determined.
