  The above-mentioned connecting hardware is useful because it is easy to connect woods. By the way, all of the above-mentioned have made a hole in the coupling member in order to insert a pin. There is no detailed description of this hole in the literature, but in order to minimize rattling during assembly, the outer diameter of the pin and the hole should be the same, or the hole should be made smaller and the pin should be driven in. Is common.

  However, when the relationship between the pin and the hole is made in this way, when the woods are connected to each other, the load is applied to the pin hole for the coupling member via the pin, and the pin hole and the end face In some cases, the distance may be short, causing cracks in the connecting member and reducing the strength of the wood.

  The present invention was developed in view of the above circumstances, and the object of the present invention is to provide a connecting structure in which the connecting work between the woods is at least as easy as the conventional one, and the end of the wood is not easily cracked. That is.

  Among the present inventions, the first and second aspects of the present invention are fixed to one member having an end face for joining in order to join two members of the longitudinal member and the transverse member, the longitudinal member and the oblique member, or the oblique member. The attachment hardware and the basic hardware fixed to the other member constitute a connection hardware, and a set of connection hardware is accommodated at the abutting location of the two members, and from the pin hole on the side surface of one member having an end surface for joining It is premised on a connecting structure for a wooden building in which a lock pin is driven in a state of penetrating the basic hardware and the accessory hardware, and the basic hardware and the accessory hardware are connected.

  Further, in both of the first and second aspects of the present invention, in one member, a housing groove is formed in the central portion of the lateral width of the end surface, and a lag screw is embedded from the bottom of the housing groove, Accommodates the accessory hardware in the center of the width and is screwed to the lag screw. On the side of one of the members, a pin hole for driving a lock pin that connects the basic hardware and the accessory hardware is made larger in diameter than the lock pin. Is a common feature.

  According to the first aspect of the present invention, the basic hardware is a U-shaped plate in plan view, and has a stopper for positioning the accessory hardware on the bottom side, and the other member is provided with a central piece of the U-shaped plate. Make a stop hole, and set the range of the two directions consisting of the opening direction of the U-shaped plate and the opposite direction of the stopper as the insertion range in which the attached hardware can be inserted, and that the attached hardware is the inner body that fits into the U-shaped plate Unique features.

  In the invention of claim 1, the basic hardware is a U-shaped plate and the accessory hardware is an inner body, but the reverse may be possible. That is, according to the invention of claim 2, the basic hardware is an inner body, a stopper for positioning the accessory hardware is projected at the lower end portion thereof, a stopper hole for stopping the inner body is formed in the other member, and the other member is formed. The range of the two directions consisting of the protruding direction of the inner body and the opposite direction of the stopper is the insertion range in which the accessory can be inserted, and the accessory is a U-shaped plate in plan view, and the inner body is fitted inside it. This is a unique feature.

  The inventions of claims 1 and 2 described above are based on the assumption that a set of connecting hardware is used to join two members of a vertical member and a horizontal member, a vertical member and an oblique member, or an oblique member. In the case where the height width of the end face of the material is large, as in the inventions of claims 3 to 6, it is assumed that a plurality of sets of connecting hardware are used apart from each other in order to join the side face of the longitudinal member and the end face of the transverse member. It is also good.

  According to the third and fourth aspects of the present invention, the transverse member is formed with an accommodation groove along the upper and lower sides in the central portion of the lateral width of the end face, and the lag screw from the bottom of the accommodation groove corresponds to the number of sets of the connecting hardware. In the middle of the horizontal width of the receiving groove, the accessory hardware is accommodated separately in the vertical direction according to the number of connected hardware and screwed to the lag screw. Has a common feature in that a pin hole into which a lock pin for connecting the basic hardware and the accessory hardware is driven has a larger diameter than the lock pin.

  Further, in the invention of claim 3, the basic hardware is a U-shaped plate in plan view, and has a stopper for positioning the attached hardware on the bottom side, and the vertical piece stops the central piece of the U-shaped plate. The stop hole is opened up and down corresponding to the number of sets of connected hardware, and the range in two directions consisting of the opening direction of the U-shaped plate and the opposite direction of the stopper is set as the insertion range in which the accessory can be inserted. Has a unique feature of being an inner body that fits into the U-shaped plate.

  In the invention of claim 3, the basic hardware is a U-shaped plate and the accessory hardware is an inner body. That is, in the invention of claim 4, the basic hardware is an inner body, a stopper for positioning the accessory hardware is projected at the lower end portion thereof, and the vertical member is provided with a stop hole for stopping the inner body, and the number of sets of connected hardware. Open the upper and lower parts corresponding to the vertical direction, and the range of the two directions consisting of the protruding direction of the inner body with respect to the vertical member and the opposite direction of the stopper is the insertion range in which the accessory can be inserted. A unique feature of the board is that the inner body is fitted inside.

  In the inventions of claims 3 and 4 described above, the housing groove is formed on the end face of the cross member along the top and bottom, and the accessory hardware is housed in the housing groove so as to be separated vertically, but the housing groove is separated vertically. The accessory hardware may be accommodated in each accommodation groove. That is, according to the fifth and sixth aspects of the present invention, the transverse member is formed with a receiving groove at the center of the lateral width of the end face so as to be separated from each other in the vertical direction corresponding to the number of sets of connecting hardware. Set the cutting area, embed a lag screw from the bottom of each receiving groove, store the accessory hardware in the center of the width on the back side of each receiving groove, screw it to the lag screw, and attach the non-cutting area to the vertical material Inserted between the base hardware, insert the accessory hardware into the base hardware, and on the side of the cross member, the pin hole for driving the lock pin that connects the base hardware and the accessory hardware has a larger diameter than the lock pin This is a common feature.

  Further, in the invention of claim 5, the basic hardware is a U-shaped plate in plan view, and has a stopper for positioning the attached hardware on the bottom side, and the vertical piece stops the central piece of the U-shaped plate. The opening direction of the U-shaped plate of multiple basic hardware, which is separated from the top and bottom by opening up and down according to the number of sets of connected hardware, is the insertion range where the accessory can be inserted. It is a unique feature that it is an inner body that fits into the U-shaped plate.

  In the invention of claim 5, the basic hardware is a U-shaped plate and the accessory hardware is an inner body. That is, in the invention of claim 6, the basic hardware is an inner body, a stopper for positioning the accessory hardware is projected at the lower end portion thereof, and the vertical member is provided with a stop hole for stopping the inner body, and the number of connected hardware sets. The protruding direction of the multiple inner bodies that are opened up and down correspondingly to the upper and lower sides is the insertion range in which the accessory can be inserted, and the accessory is a U-shaped plate in plan view. It is a unique feature that the inner body is fitted.

  There is no problem as long as the inner body has a shape that fits inside the U-shaped plate and can be fixed with wood and a lock pin. For example, although it may be a block, it is desirable to use a U-shaped plate as the inner body in plan view as in the invention of claim 7. In this way, the manufacturing cost is lower than that of the block.

  The invention of claim 8 uses a shaft instead of a lag screw, opens a female screw on the front side of the shaft, and forms a through hole on the back side, and drives a drift pin into the through hole from the side of one member. It is characterized by stopping at.

  The invention according to claim 9 is characterized in that the stopper of the basic hardware has a rod shape extending in the lateral width direction of the housing groove, and the accessory hardware is provided with a recess that fits into the stopper. Whether the invention of claim 9 can be applied to the inventions of claims 5 and 6 is a problem. If the distance between the base hardware that is separated from the top and bottom of the vertical member and the height width of the non-cutting area on the end face of the horizontal member are almost the same, the cross member is moved laterally as described above, The above-described application is not possible due to the insertion of a non-cutting region between them. However, when the height width of the non-cutting area on the end face of the cross member is narrower than the interval between the basic metal parts separated from each other up and down, it is narrower when inserting the non-cutting area between the upper and lower basic metal parts. Since there is a margin in the vertical direction, it is possible to fit the stopper and the concave portion by using the margin, and it can be said that the above-described application can be performed.

  The invention according to claim 10 is a case where a vertical member and a horizontal member are connected by a connecting hardware, and a U-shaped receiving hole penetrating in the lateral width direction of the receiving groove is formed in an upper portion of the basic hardware, and an upper portion of the accessory hardware. Is characterized in that a locking pin that locks in the receiving hole is driven and the locking pin is accommodated in the receiving groove over the entire length thereof. In addition, although the problem of whether the invention of claim 10 is applicable to the inventions of claims 5 and 6 is also a problem, the same can be said for the invention of claim 9.

  According to the first aspect of the present invention, the attachment hardware fixed to one member and the basic hardware fixed to the other member are fitted and connected by the lock pin, so that rigid joining is achieved. In addition, since the range of the two directions consisting of the opening direction of the U-shaped plate of the basic hardware fixed to the other member and the direction opposite to the stopper is the range in which the accessory can be inserted, the insertion range is wide and easy to insert. Even if the relative positional relationship between the attached hardware and the accessory is slightly deviated, the positional relationship is restored by driving the lock pin last, and an accurate connection state is obtained, so that the connection work is facilitated. Furthermore, the pin hole on the side of one member has a larger diameter than the lock pin, so the lock pin and the pin hole do not interfere with each other. Therefore, even if the lock pin is driven, the end of the wood does not crack. There is an excellent advantage. In addition, since the attachment hardware is stopped in the depth direction of the housing groove of one member by the lag screw, the load of the connection structure is not applied in the lateral width direction of the one member, and the crack at the end of the wood is compared with the conventional one. It can be said that it is hard to generate. The same effect can be obtained in the invention of claim 2.

  If it is invention of Claim 3, 4, it can apply when the height width of a timber is large, and an effect equivalent to Claim 1, 2 will be acquired.

  If it is invention of Claim 5, 6, it can apply also when the height width of a timber is large, and the effect equivalent to Claim 1, 2 is acquired. However, the connection work is slightly inferior to the first and second aspects. Because, in order to fit the attachments on the end face of the cross member into the base hardware attached to the vertical member apart from the top and bottom, try to lower the cross member and insert the receiving groove on the end face of the cross member into the base hardware. Then, since the non-cutting region of the end face of the cross member interferes with the basic hardware, it cannot be fitted. However, since the lateral direction, which is the protruding direction of the basic hardware relative to the longitudinal member, is the insertion range (insertion direction) in which the accessory can be inserted, the lateral member is moved along its longitudinal direction, and the non-cutting area is moved up and down. It is possible to insert the accessory hardware into the basic hardware by inserting it between the basic hardware. Moreover, since the non-cutting region is provided, the strength of the cross member is superior to that in which the accommodation groove is formed along the top and bottom on the end surface of the cross member (without the non-cutting region).

  If it is invention of Claim 7, since a U-shaped board is used by planar view as an inner body, compared with a block, manufacturing cost will become cheap.

  The invention of claim 8 has the same effect as that of the inventions of claims 1 to 6. However, since the shaft is used instead of the lag screw and the shaft is fixed to one member using the drift pin, the load at the time of connection is applied to the one member via the drift pin. Compared with the invention of the above, cracks at the end of the wood are likely to occur a little.

  If it is invention of Claim 9, since a stopper and a recessed part will fit and the relative positional relationship of a basic | foundation hardware and an accessory hardware will be positioned correctly, a lock pin can be driven in with a light force.

  According to the invention of claim 10, when the horizontal member with the accessory hardware is dropped from the upper side by aligning the receiving groove with the basic hardware fixed to the vertical member, the locking pin driven into the accessory hardware extends over the entire length. Since it is housed in the housing groove, the locking pin does not get in the way when the basic hardware is inserted into the accessory hardware in the housing groove, and the locking pin is caught in the U-shaped receiving hole of the basic hardware as it is. Since positioning is performed, positioning work can be easily performed.

  As shown in FIG. 3 or FIG. 7, a connecting hardware 1 is used for the first example of the connecting structure for wooden construction of the present invention. The connecting hardware 1 includes a basic hardware 3 that is fixed to the side surface of the vertical member 2 and an accessory hardware 5 that is fixed to an end surface of the horizontal material 4.

  As shown in FIG. 8, the basic hardware 3 is a U-shaped plate in plan view, and a plurality of through holes 7 are formed in the central piece 6 of the U-shaped plate, and a vertical member is formed as shown in FIG. 1. 2 pierce a stop hole 8 at a location corresponding to the hole 7, screw a lag screw 9 into the stop hole 8, and fix the lag screw 9 in the vertical member 2 with a male screw on its outer peripheral surface. It is. When the lag screw 9 is screwed, a tool is screwed into the female screw on the end face. Then, the central piece 6 is pressed against the lateral width central portion of the side surface of the vertical member 2, and the central piece 6 is fixed with the screw N from the through hole 7 to the female screw inside the lag screw 9. The head of the screw N can be attached with a tool such as a hexagon bolt. In addition, a flat stopper 10 is provided at the bottom of the U-shaped plate, and the accessory hardware 5 can be inserted in a range in two directions, the lateral direction that is the opening direction of the U-shaped plate and the upward direction that is opposite to the stopper. As shown in FIG. 4, the accessory 5 is placed on the stopper 10 and positioned. As shown in FIGS. 1 and 8, the stopper 10 is provided on the front side of the U-shaped plate, thereby forming a dust / dust discharge port 11 on the inner side of the U-shaped plate. The left piece 12 and the right piece 13 of the U-shaped plate are drilled through a lock hole 15 into which a lock pin 14 (see FIG. 5) is driven, and the accessory 5 is also provided with a lock hole 15 as shown in FIGS. A hole 16 to be locked is formed at a position corresponding to. In the drawing, the lock holes 15 and the locked holes 16 are provided in a vertical row, but may be provided in parallel.

  The accessory 5 is an inner body U accommodated in a U-shaped plate as shown in FIG. 9, and a prismatic block is used as the inner body U. As shown in FIG. 2, on the end face of the cross member 4 that stops the accessory hardware 5, an accommodation groove 17 that accommodates the connection hardware 1 is formed in the central portion of the lateral width along the vertical direction. A plurality of round holes 18 are formed in the part at intervals in the height direction. As shown in FIGS. 2 and 3, a lag screw 19 is screwed into the round hole 18, the accessory hardware 5 is pressed against the back of the receiving groove 17, and the lag screw 19 is inserted into the vertical hole surface side of the accessory hardware 5. When the screw is fixed to the female screw, a space for accommodating the left piece 12 and the right piece 13 of the U-shaped plate is formed on both sides of the attachment hardware 5. The through hole 20 on the vertical member surface side of the accessory 5 has a counterbore shape to accommodate the head of the screw. As shown in FIGS. 2 and 3, a pin hole 21 into which the lock pin 14 is driven is formed on the side surface of the cross member 4 at a position corresponding to the locked hole 16 on the side surface of the accessory 5 and has a larger diameter than the lock pin 14. It is open.

  Therefore, as shown in FIG. 4, when the end of the longitudinal member 2 is pressed against the side surface of the cross member 4 and the basic hardware 3 is inserted into the receiving groove 17 of the cross member 4, the basic hardware 3 and the attached hardware 5 are The lock hole 15 of the basic hardware 3, the locked hole 16 of the accessory hardware 5, and the pin hole 21 on the side of the cross member 4 are in a straight line. Then, as shown in FIG. 5, the lock pin 14 is driven into the pin hole 21 and press-fitted, and the base metal 3 and the accessory hardware 5 are firmly and rigidly joined by the lock pin 14. Then, since the pin hole 21 has a large diameter as described above, the diameter of the pin hole 21 is not widened by the lock pin 14, and the transverse member 4 can be prevented from cracking. Finally, as shown in FIG. 6B, the lock pin 14 is made shorter than the width of the cross member 4, so that the blindfold 22 that hides the lock pin 14 is placed on the left and right sides of the pin hole 21 of the cross member 4. Stuff from. As a result, the lock pin 14 is not exposed to fire in the event of a fire, and fire resistance is improved. Further, as shown in FIG. 6 (a), since the height width of the connecting hardware 1 is made narrower than the height of the receiving groove 17, the blinding material 22 that hides the connecting hardware 1 is packed from both the upper and lower sides of the receiving groove. . As a result, the connecting hardware 1 is not exposed to fire in the event of a fire, and the fire resistance is improved.

  In the second example of the connecting structure for wooden construction of the present invention, the same connecting hardware 1 as in the previous example is used as shown in FIGS. 10 (a) and 10 (b), but the shaft 23 is used in place of the lag screw 19 of the previous example. . A female screw is opened on the front end surface of the shaft 23, and a through hole 24 is opened in the lateral width direction on the back side of the shaft 23. Then, the drift pin 26 is driven through the support hole 25 formed in the side surface of the cross member 4 to penetrate the through hole 24, and the shaft 23 is embedded in the back of the housing groove 17. The drift pin 26 is accommodated in the cross member 4 in a state in which the support hole 25 is slightly expanded. Then, the accessory 5 is screwed to the shaft 23 in the same manner as in the previous example. The shaft 23 has a pipe shape in the drawing, but may have a rod shape. On the other hand, the basic hardware 3 is screwed by using the retaining holes 8 of the vertical member 2, and bolts and nuts 27 and 28 are used for screwing.

  As shown in FIG. 11, the same connection hardware 1 as the previous example is used in the third example of the connection structure for a wooden building of the present invention. In the case of this connection structure, the fixing object of the basic hardware 3 and the accessory hardware 5 is changed, that is, the basic hardware 3 is fixed to the upper and lower surfaces of the cross member 4, and the accessory hardware 5 is fixed to the end surface of the vertical member 2. There is a big difference. In order to fix the two vertical members 2 on the same straight line of the upper and lower surfaces, the cross member 4 is formed by penetrating a plurality of stop holes 8 vertically and embedding lug screws 9 in the stop holes 8. Female screws are opened on the upper and lower end surfaces of the screw 9, and the basic hardware 3 is screwed to the female screws from above or below. Then, the movement of the accessory hardware 5 in the lateral direction is restricted by the stopper 10 of the basic hardware 3. On the other hand, the vertical member 2 has an accommodation groove 17 formed on its end face, and the accessory hardware 5 is screwed using the accommodation groove 17 in the same manner as in the previous example.

  As shown in FIGS. 12 and 13, the same connection hardware 1 as the previous example is used in the fourth example of the connection structure for a wooden building of the present invention. This connecting structure joins the vertical member 2 and the diagonal member 29, and the end surface of the vertical member 2 and the receiving groove 17 of the end surface are formed to be inclined in accordance with the inclination of the diagonal member 29. The attachment hardware 5 is fixed similarly to the previous example. On the other hand, when the basic hardware 3 is fixed to the lower surface of the diagonal member 29, the stopper 10 of the basic hardware 3 is directed toward the roof top side. In this way, when the diagonal member 29 is lowered from above the vertical member 2 and the accessory 5 is fitted into the basic hardware 3, the stopper 10 is hooked on the accessory 5 and the diagonal material 29 is positioned.

  In the fifth example of the connecting structure for wooden construction of the present invention, as shown in FIG. 14, the same connecting hardware 1 as the previous example is used. This connection structure is different from that of the fourth example except that the inclined end surfaces of the vertical member 2 and the diagonal member 29 are joined to each other.

  In the sixth example of the connecting structure for a wooden building of the present invention, as shown in FIG. This connection structure is the same as that of the fifth example except that the connection structure is used for the roof top part and the two diagonal members 29 are joined.

  In the seventh example of the connection structure for wooden construction of the present invention, as shown in FIG. 16, the same connection hardware 1 as the previous example is used. This connection structure is used when a roof is formed, and the longitudinal member 2 and the diagonal member 29 are assembled in advance so that the end surface of one diagonal member 29 is obliquely separated from the upper end surface of the longitudinal member 2. The difference is that another diagonal member 29 is installed between the longitudinal member 2 and the diagonal member 29 which are separated from each other. In this case, one end surface of the diagonal member 29 for construction is formed perpendicularly to the end surface of the diagonal member 29 assembled beforehand, and the other end surface of the diagonal member 29 for construction is aligned with the inclined surface of the longitudinal member 2. Inclined. The housing grooves 17 are formed on both end surfaces of the diagonal member 29 for installation according to the angle of the end surfaces, and the accessory hardware 5 is stopped in each housing groove 17. On the other hand, it is important that the base metal 3 is fixed to the end surfaces of the longitudinal member 2 and the diagonal member 29 assembled in advance, and the stopper 10 of each base metal 3 is directed downward. In this way, the insertion range R in which the accessory 5 can be inserted is a range in which the basic hardware 3 fixed to the diagonal member 29 is in two directions, upward and lateral, while the basic hardware fixed to the vertical material 2 is provided. 3 is a two-way range of diagonally upward directions on the left and right. Accordingly, when the construction diagonal member 29 is lowered, strict positioning is not required, and if the accessory 5 attached to the end face of the construction diagonal member 29 is positioned with sufficient accuracy to be caught by each stopper 10, the construction material is lowered. The left and right stoppers 10 support the both ends of the diagonal member 29 for installation. Finally, if the lock pin 14 is driven, the connecting operation is completed, so that the connecting operation is facilitated.

  Note that the base metal 3 is fixed to one of the construction diagonal members 29 shown in FIG. 16, for example, the right end surface without forming the receiving groove 17, and the stopper 10 of the base metal 3 is disposed above. The same effect can be obtained by forming the accommodation groove 17 on the end face of the corresponding member (slanting material 29) assembled in advance and fixing the accessory 5 to the accommodation groove 17. Further, the base hardware 3 is fixed without forming the receiving grooves 17 on both end surfaces of the construction diagonal material 29, the stoppers 10 of the basic hardware 3 are disposed above, and the longitudinal material 2 and the diagonal material assembled beforehand. Even when the housing grooves 17 are formed on the end faces 29 and the accessory hardware 5 is fixed to the housing grooves 17, the same effect can be obtained.

  In the eighth example of the connecting structure for wooden construction of the present invention, another connecting hardware 1 is used as shown in FIGS. The basic hardware 5 of the connection hardware 1 is a U-shaped plate in plan view, but as shown in FIGS. 17 and 18, the left and right pieces 12, 13 are punched downward in addition to the lock hole 15. 30 are opposed to each other, the rod-shaped stopper 10 is driven into the opposing hole 30, the stopper 10 is installed on the left and right pieces 12, 13, and both ends of the stopper 10 are accommodated in the left and right pieces 12, 13. A U-shaped receiving hole 31 is formed in the upper part. On the other hand, the accessory 5 has an inverted U-shaped recess 32 that fits into the stopper 10 at the bottom, and an opening 33 at a location corresponding to the receiving hole 31 at the top. As shown in (b), the locking pin 34 is driven into the hole 33 so that the left and right end portions 35 of the locking pin 34 project in a protruding manner on the left and right sides of the inner body (block) U. Note that the left and right end portions 35 of the locking pin 34 are accommodated in the accommodation groove 17 and are not visible from the side surface of the cross member 4.

  In this case, the method of fixing the basic hardware 3 to the vertical member 2 and the method of fixing the accessory 5 to the horizontal member 4 are the same as in the first example as shown in FIGS. 17 and 18, but as shown in FIG. The attachment metal 5 attached to the cross member 4 is dropped from above the basic metal 3 attached to the vertical member 2, and the locking pin 34 and the stopper 10 are fitted into the receiving hole 31 and the recess 32, respectively. Further, after fitting in this way, the lock pin 14 is driven through the pin hole 21 on the side surface of the cross member 4 as shown in FIG.

  As shown in FIG. 21, another connecting hardware 1 is used for the ninth example of the connecting structure for wooden construction of the present invention. The connection hardware 1 can be considered as a replacement of the U-shaped plate of the basic hardware 3 of the connection hardware 1 of the first example and the inner body (block) U of the accessory hardware 5. In detail, the basic hardware 3 is the inner body U, and a plate-like stopper 10 for positioning the accessory 5 is projected to the left and right at the lower end thereof, and the protruding direction of the inner body U relative to the longitudinal member 2 and the stopper 10 Is the insertion range R in which the accessory 5 can be inserted, the lock hole 16 for the lock pin is made on the side surface, and the screw is fixed on the side surface side A punched hole 20 is formed. On the other hand, the accessory 5 is a U-shaped plate in plan view, and a lock hole 15 for a lock pin is formed in the left and right pieces 12 and 13, and a screw hole 7 is provided in the center piece 6. . In addition, what is necessary is just to perform the method of stopping the base metal fitting 3 and the attachment hardware 5 to the vertical member 2 and the horizontal member 4 similarly to a previous example.

  As shown in FIG. 22, another connecting hardware 1 is used for the tenth example of the connecting structure for wooden construction of the present invention. The connecting hardware 1 is characterized in that the inner body U up to the previous example is not a block but a U-shaped plate. That is, the basic hardware 3 is formed by an inner body (U-shaped plate) U that is slightly smaller than the attached hardware 5, and the stopper 10 is provided at the lower end of the U-shaped plate U. In this case, the central piece 36 of the U-shaped plate U is screwed to the vertical member 2, the attached hardware 5 is placed on the stopper 10, and the left and right pieces 37, 38 of the basic hardware 3 are slightly larger than the U-shaped plate. Fits inside the accessory hardware 5. Then, the vertical member 2 and the horizontal member 4 are connected through the lock pin 14 through the lock hole 15 of the left and right pieces 12 and 13 of the accessory 5 and the locked hole 16 of the left and right pieces 37 and 38 of the basic hardware 3. To do. In this way, both the basic hardware 3 and the accessory hardware 5 are U-shaped plates, and the bottom side is closed by the stopper 10, so that a substantially prismatic heat insulating space 39 is opened upward inside the mated two. After the lock pin 14 is driven, the heat insulating space 39 can be filled with a heat insulating material such as urethane foam to improve the heat insulating effect.

  As shown in FIG. 23, the eleventh example of the connecting structure for wooden construction of the present invention is characterized in that a plurality of sets of connecting hardware 1 are used. This is a method used when the height width of the cross member 4 is large. With the cutting tool such as a circular saw, the receiving grooves 17 are separately formed on the upper and lower sides of the cross member 4, and there is no gap between the upper and lower receiving grooves 17. The cutting area 40 is formed to suppress the decrease in the wood strength as much as possible. When the accessory 5 is stopped in each receiving groove 17 on the end face of the cross member, the non-cutting area 40 becomes an obstacle, and at first glance, the accessory 5 cannot be fitted into the basic hardware 3 attached to the longitudinal member 2. feel. However, each base hardware 3 has a lateral direction as an insertion region R into which the accessory hardware 5 can be inserted. Therefore, the lateral metal 4 is viewed from the lateral direction toward the vertical distance between the two basic hardware 3 fixed to the vertical material 2. If the non-cutting region 40 is inserted, the accessory 5 on the end face of the cross member is fitted to the basic metal 3 and is temporarily supported. Therefore, when the lock pin 14 is driven last, the longitudinal member 2 and the transverse member 4 are connected.

  In addition, although not illustrated, the structure which eliminated the non-cutting area | region 40 among the 11th examples mentioned above may be sufficient. That is, the accommodation groove 17 may be formed along the vertical direction on the end face of the cross member, and the attachment hardware 5 may be vertically separated and stopped in the accommodation groove 17. In this case, although the strength of the cross member 4 is reduced, there is no non-cutting region 40 when the attachment 5 attached to the cross member 4 is fitted into the basic metal piece 3 attached to the vertical member 2 apart vertically. Since the range in the two directions of the upward direction and the lateral direction can be set as the insertion range R in which the accessory 5 can be inserted, there is an advantage that the connecting operation can be easily performed.
