Description

  The present invention relates to a connection structure for integrating members such as columns and beams in a wooden building.

  Although there are various methods of connecting the members which become the framework of the wooden building, in order to secure the positional accuracy and the rigidity, the hoso is inserted into the hoso hole and the members are often strongly restrained. However, the insertion of the hoso and the hoso hole increases labor of processing and construction of the members, and there is a problem such as a reduction in strength due to a cross section defect, and various kinds of hardware are often used in recent years. A metal object is embedded in a round hole, a slit, or the like processed into a member, so cross-sectional defects are suppressed to the necessary minimum, and the strength is excellent. In addition, by making lumber with a machine tool and attaching a hardware to a member in advance, not only accuracy improves but also working time at the time of construction is shortened.

  The following patent documents can be cited as examples of techniques related to the present invention. Patent Document 1 discloses, in a large-scale wooden construction, a connection metal that integrates two members, a longitudinal member and a cross member. This connection hardware uses a basic hardware to be attached to the longitudinal member and an attachment to be attached to the cross member, and a taper portion and a receiving portion are provided at the end of each hardware, and one tapered portion is inserted into the receiving portion of the other , Adhere both hardware. In addition, both metal parts are attached to a longitudinal member or cross member through a lag screw and a bolt.

  Patent Document 2 discloses a connector that integrates a plurality of members. This connector is composed of a lag screw, an embedment tool, a stud bolt, etc. The lag screw is embedded in one member, the embedment tool is embedded in the other member, the lug screw and the embedment tool are pulled by the stud bolt, Unify.

  In recent years, wooden buildings have been increasingly introduced to large-scale commercial facilities such as local products sales offices and restaurants, and the interior of the room exposes members such as pillars and beams to create a natural atmosphere. There are many things. However, since a large-sized hardware such as that described in Patent Document 1 is used to connect the members, the hardware can be easily viewed from the room, and the natural atmosphere is lost. Although it can be eliminated by embedding the whole in a member like the coupler disclosed by the said patent document 2 about this point, the coupler of the patent document 2 has a limited application and poor versatility. In addition, the use of an adhesive increases the time and labor during construction.

  In addition, in order to integrate a hardware with a member, a bolt, a screw nail, a drift pin, etc. are needed separately. In order to press the surface of a member, a bolt takes measures, such as incorporating a washer, but there exists a possibility that a lock may occur due to the depression of the washer due to aging. In addition, the drift pin may also spread the surrounding wood to cause loosening. Further, in each of the bolt and the screw nail, each part gradually deforms with the passage of time, and its head is loosened, so that the rigidity of the connection structure tends to be reduced.

  The present invention has been developed based on such a situation, and aims to provide a connected structure which is excellent in aesthetics without exposure of hardware and the like and capable of suppressing loosening due to age-related deformation.

The invention according to claim 1 for solving the above-mentioned problems is a connecting structure for connecting one member and the other member, wherein the indwelling device attached to the one member is disposed to be in surface contact with the indwelling device and Using an adhesive attached to the other member, a bolt for pulling and integrating the indwelling device and the adhesive, and a screw for attaching the indwelling device and the adhesive, the stem of the bolt is used in the indwelling device. A hole through which the screw is inserted, and the contact device is provided with a female screw to be screwed with the bolt, and in both the indwelling device and the contact device, a nail hole into which a shaft of the screw is inserted; A counterbore for accommodating the head of the head, a tool hole concentric with the bore and penetrating both surfaces is provided in the one member, and the head of the bolt is accommodated on the indwelling tool side of the tool hole A large diameter hole is provided, and the shank of the bolt passes through the bore. The screw is screwed to the female screw, and the one member and the other member are connected, and the head of the screw nail is pressed by the head of the contact device or the indwelling device or the other screw nail to prevent the floating thereof. Citea is, to prevent slipping at the contact surface between the contact member and the retaining device, is provided with one recess on one side of this plane, the convex portion on the other side of which fits the recess It is a connection structure characterized by providing .

  The present invention is intended to connect structural members to each other in a wooden building such as a house or a commercial facility, and is assumed to be used in all locations, and one of two members to be connected is one of the members. The remaining one is called the other material. In addition to natural wood, various types of laminated wood can also be used as one or the other wood. Also, the arrangement of one member and the other member is free, and in addition to connecting the two members in a T-shape or an L-shape, it is also possible to integrate two bars arranged in parallel to make a large cross section. However, due to the structure, the end faces of the two bars can not be integrated.

  The indwelling device and the intimate contact device are a pair of metal plates disposed at the boundary of the two members. Then, the indwelling device is fixed to one material, the close contact device is fixed to the other material, the surfaces of the indwelling device and the close contact device are brought into contact, and the two members are connected by integrating both. Therefore, the outer shapes of the pair of the indwelling device and the contact device are basically the same. However, the outer shape of the indwelling device and the adhesion device can be freely determined in accordance with various factors, and may be rectangular as well as round. In addition, in order to embed an indwelling tool or an adhesion tool on the surface of one material or the other material, a holding groove may be processed.

  The bolt is for unifying the indwelling device and the intimate contact device and bringing both surfaces into contact without any gap, and is inserted from the indwelling device toward the intimate contact device. Therefore, in order to insert the shaft portion of the bolt in the indwelling device, a through hole is formed through both surfaces, and in the close contact device, a female screw is formed at a position concentric with the through hole. In addition, since a bolt contacts only an indwelling tool and an adhesion tool, it does not press a member even after tightening. In addition, a bolt is a part which substantially carries out connection of two members, and depending on the required strength, a plurality of bolts may be used in a pair of indwelling device and intimate contact device.

  The screw nail is for attaching the indwelling device or the adhesion device to one member or the other member, and a general-purpose product may be used as it is. However, where the strength is required, large diameter ones are used. In addition, in order to insert a screw nail, in addition to forming a nail hole which penetrates both surfaces in the indwelling tool and the adhesion tool, a counterbore for accommodating the head of the screw nail is formed at the entrance of the nail hole. Besides, it is premised that multiple screw nails are inserted into one indwelling device or close contact device, and the insertion direction of the screw nails is intentionally changed (for example, "C" shape) to improve the pullout strength. You can also

  The tool hole is for inserting a tool for tightening a bolt that integrates the indwelling device and the adhesion device, and penetrates both sides of one material. In the present invention, since the bolt is inserted from the indwelling device toward the contact device, the head of the bolt inevitably bites into the inside of one material. Therefore, in one material, the tool hole is machined at a position concentric with the bolt, the tool is inserted into the hole, and the bolt is tightened. In order to keep the inner diameter of the tool hole to the minimum necessary, it is preferable to use a bolt provided with a concave such as a hexagonal hole at its head, and a bar wrench as the tool.

  The large diameter hole is a cavity that is machined into the inside of one material in order to accommodate the head of the bolt, and is disposed at one of the two ends of the tool hole that contacts the detainer. In the present invention, in order to embed a bolt in one material, a large diameter hole is indispensable, but the size is kept to the minimum necessary in consideration of the appearance and the cross section of the member. However, at the time of construction, a certain extension is necessary to draw the tip of the bolt into the inside of the detainer.

  The screw nail is inserted from the indwelling device or the adhesion device toward one member or the other, but the head is brought into contact with the adhesion device or the indwelling device or the other screw nail to prevent the screw nail from rising. In order to realize this, the depth of the counterbore etc. is adjusted so that the head of the screw nail is aligned with the surface of the indwelling device or the contact device without any level difference. In addition, when a nail hole is formed in the diagonal direction with respect to the surface of an indwelling tool or an adhesion tool, it is difficult to press the head with the adhering tool or the indwelling tool which opposes. In such a case, opposing screw nails are placed back-to-back to bring both heads into contact.

  As described above, after attaching the indwelling device or the adhesion device to one member or the other member by screw nails, the indwelling device and the adhesion member are pulled together with a bolt to integrate the one member and the other member. Each part of the bolt and screw nail is embedded inside the member, and the metal part is not exposed to the outside at all, so it is excellent in appearance. In addition, by bringing the head of the screw nail into contact with the adhesion tool or the like to prevent the screw nail from rising, it is possible to suppress the loosening of the connection structure due to aging or the like.

In addition, in order to prevent slippage between the indwelling device and the intimate contact device , some unevenness is provided on both contact surfaces. This unevenness contributes to the transmission of a shear load, and also plays a role of preventing the rotation of the indwelling device and the intimate attachment when the indwelling device and the intimate contact are pulled with only one bolt. As a matter of course, the shape and arrangement of the asperities may be freely determined as long as there is no problem in inserting the screw nails and the like.

  As in the invention according to claim 1, using the indwelling device, the adhesion device, the bolt, and the screw nail as the connection structure between the one material and the other material, attaching the indwelling device and the adhesion device to the one or the other material with the screw nail Furthermore, by pulling together the indwelling device and the adhesion device with a bolt and integrating one material and the other material, each part of the indwelling device, the adhesion device, the bolt and the screw nail can be embedded in the inside of the member. Excellent appearance because it is not exposed to the outside. The tool hole can be made as small as possible without causing any problem during construction without affecting the appearance, and if a piece of wood is stuffed into the tool hole, the trace can be completely erased.

In addition, the head of the screw is in contact with the clasp or detent or other screw to prevent the screw from loosening. Therefore, even when a gap is generated in the boundary between the indwelling device and one member or in the boundary between the adhesion member and the other member due to contraction of members due to aging or elongation of the shaft of screw nails, both are integrated without loosening. Maintain a state of Due to this characteristic, the rigidity decrease of the connection structure is suppressed even after the occurrence of the secular deformation or after the application of the excessive load, and the safety is excellent. In addition, by providing a recess and a protrusion on the contact surface between the indwelling device and the contact device, when one member and the other member are integrated, the protrusion fits into the recess and the sliding load is large even when the shear load is large. Can be prevented.

  FIG. 1: is an example of the connection structure by this invention, and assumes connecting two members called the one material used as the frame | skeleton of a wooden building, and the other material in L shape. One member is an upright column 41, and the other member is a horizontally extending beam 51, and the both members are integrated by the indwelling device 11, the contact device 21, the bolt 31, and the screw 60. Among them, the indwelling device 11 and the intimate contact device 21 are circular metal plates and equal in diameter and thickness, arranged concentrically to bring the surfaces into contact with each other. Further, the bolt 31 is used to integrate the indwelling device 11 and the intimate contact device 21. The screw nail 60 is used to attach the indwelling device 11 and the adhesion device 21 to the column 41 and the beam 51, respectively.

  The indwelling device 11 and the adhesion device 21 have a size that can be embedded inside the column 41 and the beam 51, and the side surface of the column 41 has the holding groove 46 for embedding the indwelling device 11 processed. On the end face of 51, a holding groove 56 for embedding the adhesion tool 21 is processed. The depth of any of the holding grooves 46 and 56 is equal to the thickness of the indwelling device 11 and the adhesion device 21 to be embedded, and when the indwelling device 11 and the adhesion device 21 contact, the side surface of the column 41 and the end surface of the beam 51 are also Contact. The inner diameters of the holding grooves 46 and 56 may be larger than the outer diameters of the indwelling device 11 and the adhesion device 21 to be embedded, but may be the same from the viewpoint of strength.

  The screw nail 60 is used to integrate the indwelling device 11 and the adhesion device 21 embedded in the holding grooves 46 and 56 with the column 41 and the beam 51. As a matter of course, the size and the number of the screw nails 60 are determined based on the assumed load, and in this case, both of the indwelling device 11 and the adhesion device 21 are inserted in two. Corresponding to this, the indwelling device 11 and the adhesion device 21 are formed with a nail hole 33 into which the shaft portion of the screw nail 60 is inserted, and one end of the nail hole 33 is a counterbore that accommodates the head of the screw nail 60 36 is formed. The head of the inserted screw nail 60 is aligned with the surface of the indwelling device 11 and the contact device 21 without a step due to the counterbore 36.

  The indwelling device 11 and the intimate contact device 21 are integrated with one bolt 31. Therefore, in order to insert the shaft portion of the bolt 31 into the indwelling tool 11, in addition to forming the inner hole 37, the close fitting 21 is formed with a female screw 34 screwed with the bolt 31. In this case, a bolt with a hexagonal hole is used as the bolt 31 in this figure, and is rotated by a bar wrench 39 with a hexagonal cross section. Further, both the bore 37 and the female screw 34 are located at the center of the indwelling device 11 and the adhesion device 21. In order to accommodate the head of the bolt 31, a large diameter hole 48 for accommodating the head of the bolt 31 is processed at the center of the back surface of the holding groove 46 of the column 41.

  The large diameter hole 48 has an inner diameter that does not prevent the rotation of the bolt 31, and in consideration of the tightening operation, has a depth sufficient to accommodate the tip of the bolt 31 in the center hole 37. A tool hole 47 is machined at the center of the back surface of the large diameter hole 48 in order to insert a bar wrench 39. Although the tool hole 47 inevitably penetrates to the opposite surface of the holding groove 46, its inner diameter prevents the deterioration of the appearance as the minimum necessary for inserting the bar wrench 39. Therefore, tool holes 47 having different inner diameters and large diameter holes 48 are arranged concentrically.

  In addition, in order to prevent relative twist between the column 41 and the beam 51, a total of four sets of concave portions 38 and convex portions 35 are formed on the contact surface between the indwelling device 11 and the adhesion member 21. The concave portion 38 is on the side of the indwelling tool 11, and the convex portion 35 is on the side of the adhesion tool 21. By fitting the concave portion 38 and the convex portion 35, in addition to preventing twisting, it is responsible for transmission of a shear load. In the indwelling device 11 of this figure, the nail holes 33 are arranged at the upper and lower two places, and the concave portion 38 is formed at a position away from the nail holes 33. On the other hand, in the adhesion tool 21, the convex portion 35 is formed at a position where the nail holes 33 are arranged at the left and right two places and aligned with the concave portion 38.

  FIG. 2 shows a state in which the indwelling device 11 of FIG. 1 is attached to the column 41 and the adhesion device 21 is further attached to the beam 51. Prior to connecting the column 41 and the beam 51 in FIG. 1, the indwelling device 11 and the adhesion device 21 are embedded in the respective holding grooves 46 and 56 as shown in this figure, and these are fixed with the screw nail 60. In addition, the screw nails 60 inserted into the indwelling device 11 are upper and lower two, and the screw nails 60 inserted into the adhesion device 21 are two left and right. Further, before attaching the indwelling device 11 to the column 41, the bolt 31 accommodates the head thereof in the large diameter hole 48 and inserts the shaft portion into the center hole 37.

  After the attachment of the indwelling device 11 and the adhesion device 21 is finished, the surface of the indwelling device 11 is aligned with the side surface of the column 41 without any level difference, and the tip of the bolt 31 protrudes from the center hole 37 thereof. However, this tip can be easily pushed in and the whole can be inserted into the hole 37. Further, the surface of the adhesion tool 21 is aligned with the end face of the beam 51 without any step. However, only the four convex portions 35 project from the surface. The head of the screw nail 60 is aligned with the surface of the indwelling device 11 and the adhesion device 21 without any level difference. Therefore, the head of the screw nail 60 on the side of the column 41 contacts the surface of the adhesive 21, and the head of the screw nail 60 on the side of the beam 51 contacts the surface of the indwelling tool 11.

  FIG. 3 shows a state in which the column 41 and the beam 51 of FIG. 2 are connected. The indwelling device 11 and the adhesion device 21 are completely embedded in the column 41 and the beam 51, and they are drawn by a single bolt 31, and the side surface of the column 41 and the end surface of the beam 51 are in contact. The head of the screw nail 60 inserted into the column 41 is in contact with the contact device 21 and restrained as shown in the longitudinal sectional view. Therefore, the indwelling device 11 and the screw nail 60 are integrated in a non-displaceable manner, and the connection structure is not loosened even when the screw nail 60 or the member is deformed with time. The head of the screw nail 60 inserted into the beam 51 is also in contact with the indwelling tool 11 and restrained. In addition, the convex portion 35 and the concave portion 38 fit in and transmit a shear load, so that the load of the bolt 31 is reduced.

  It is assumed that attachment of the indwelling tool 11 and the adhesion tool 21 is performed at a lumber shop etc. At the site, the pillar 41 and the beam 51 are made to approach, the convex part 35 and the concave part 38 are fitted, and the bolt 31 is tightened. The connection of the beam 51 is completed, and the workability is good. For tightening of the bolt 31, various electric tools can be used besides the L-shaped bar wrench 39 as shown in the figure. In addition, it is possible to pack the same kind of wood as the pillars 41 in the tool holes 47 and completely cover the internal structure, which is excellent in appearance.

  FIG. 4 shows a connecting structure for attaching the lower end of the obliquely extending climbing beam 52 to the column 41. Also in this figure, the indwelling device 12 and the intimate contact device 22 are circular, attach the indwelling device 12 to the column 41, attach the indwelling device 22 to the climbing beam 52, and place the indwelling device 12 and the indwelling device 22 in the same manner as FIG. Pull it with bolt 31. However, in order to insert the screw nail 60 in the longitudinal direction of the uplift beam 52, the nail hole 33 of the adhesion tool 22 has an intersecting angle with the surface of the adhesion tool 22. Therefore, when the screw nail 60 is tightened, about half of its head protrudes from the counterbore 36. In order to cope with this, the nail holes 33 of the indwelling tool 12 are also aligned at the same angle as the adhesion tool 22 side, and both nail holes 33 are concentrically aligned, and the heads of the screw nails 60 facing each other back to back Contact.

  In each of the indwelling device 12 and the adhesion device 22, three nail holes 33 are arranged side by side. Therefore, the inner hole 37 and the female screw 34 into which the bolt 31 is inserted are disposed at one upper position, and the convex portion 35 and the concave portion 38 for transmitting a shear load are disposed at a lower position. The convex portion 35 and the concave portion 38 are arranged reversely to those in FIG. 1, and the indwelling tool 12 is the convex portion 35. As described above, the details are free as long as the convex portion 35 and the concave portion 38 are responsible for transmission of a shear load. In addition, the tool holes 47 and the large diameter holes 48 to be machined into the columns 41 are biased upward, not the center of the holding groove 46, in order to correspond to the arrangement of the middle holes 37 and the female threads 34.

  FIG. 5 shows a state in which the indwelling device 12 of FIG. 4 is attached to the column 41 and the adhesion device 22 is further attached to the uplift beam 52. Prior to connecting the column 41 and the climbing beam 52 in FIG. 4, the indwelling device 12 and the adhesion device 22 are embedded in the holding grooves 46 and 56 and fixed with screws 60. Since all the screw nails 60 extend in the longitudinal direction of the climbing beam 52, the nail holes 33 have an intersecting angle with the surfaces of the detainer 12 and the adhesive 22. The counterbore 36 is adjusted in depth so that only half of the head of the screw nail 60 protrudes from the surface. Accordingly, the head of the screw nail 60 inserted into the column 41 has its lower half protruding from the surface of the detainer 12, and the head of the screw nail 60 inserted into the climbing beam 52 has its upper half an adhesive 22 Project from the surface.

  The screw nails 60 extend obliquely along the climbing beams 52. However, the bolt 31 is disposed in the horizontal direction, and the convex portion 35 protrudes in the horizontal direction. Therefore, the arrangement of each part is determined so that the bolt 31 and the projection 35 do not contact the screw nail 60. Furthermore, the screw nail 60 should not block the tool hole 47. In addition, the indwelling device 12 is aligned with the side surface of the column 41 without any level difference, and only the head of the screw nail 60 and the projection 35 project. Similarly, the adhesion tool 22 is aligned with the end face of the climbing beam 52 without any level difference, and only the head of the screw nail 60 projects.

  FIG. 6 shows a state in which the column 41 and the up beam 52 in FIG. 5 are connected. The indwelling tool 12 and the adhesion tool 22 are completely embedded in the column 41 and the rising beam 52, and they are drawn by a single bolt 31, and the side surface of the column 41 and the end surface of the rising beam 52 are in contact. As shown in the longitudinal sectional view, the side of the column 41 and the side of the up beam 52 are aligned back to back in a straight line, and the head portions of the screw 60 are in contact with each other. Therefore, the compressive load acting on the column 41 and the climbing beam 52 is also received by the screw nail 60 in addition to the detention tool 12 and the adhesion tool 22, and the end surface of the climbing beam 52 is prevented from sinking in the side surface of the column 41 There is.

  FIG. 7 shows a connection structure for attaching the lower end of the obliquely extending upward beam 52 to the column 41 in the same manner as FIG. 4, but it is assumed to be used at a place where a larger load acts. The indwelling device 13 and the intimate contact device 23 in this figure are rectangular extending in the vertical direction, and the nail holes 33 are provided at six locations. Also, two bolts 31 are used at the top and the bottom. Therefore, two sets of the tool hole 47 and the female screw 34 are provided at the top and the bottom. Besides, four pairs of convex portions 35 and concave portions 38 for transmitting a shear load are provided at positions away from the nail holes 33. In the screw nail 60, as in the case of FIG. 6 above, the pillar 41 side and the climbing beam 52 side are aligned back to back in a straight line, and the head parts of both are in contact with each other.

  The indwelling device 13 and the adhesion device 23 are embedded in the holding grooves 46 and 56 and completely concealed after installation. Further, by using two bolts 31, the strength against a tensile load can be further improved, and bending moment can be countered. Besides, the center hole 37 and the female screw 34 are disposed on the center line of the indwelling tool 13 and the adhesion tool 23 so that the screw nail 60 does not contact the bolt 31 or the like, and the nail hole 60 is disposed away from the center line.

  In this figure, the indwelling device 13 and the adhesion device 23 are embedded in the holding grooves 46 and 56. However, when problems such as appearance and condensation do not occur, the holding grooves 46 and 56 are omitted. You may attach the indwelling tool 13 or the close_contact | adherence tool 23 to the end surface of 52 as it is. However, even in such a case, the point at which the head of the screw nail 60 is brought into contact with one another to prevent the floating thereof and the point at which the entire bolt 31 is embedded inside and tightened via the tool hole 47 can not be changed.

  FIG. 8 shows a state in which the column 41 and the up beam 52 in FIG. 7 are connected. The indwelling device 13 and the adhesion device 23 are completely embedded in the column 41 and the rising beam 52, and these are drawn by the upper and lower two bolts 31 so that the side surface of the column 41 and the end surface of the rising beam 52 are in contact. Although partially omitted in this figure, six screw nails are inserted into the column 41 and the up beam 52, and as in the longitudinal cross-sectional view of FIG. Both heads are in contact with each other. The present invention can be used to connect members of various sizes by adjusting the number of screw nails 60 and bolts 31, and is excellent in versatility and flexibility.

And, in order to attach the end face of the horizontal member 53 and the diagonal member 54 to the side surface of the column 41, the connection structure according to the present invention is used. The connection structure of the wooden truss is drawn in an enlarged manner in the upper part of FIG. 9. Here, the horizontal members 53 and the diagonal members 54 overlap vertically, and the end surfaces of both members are in contact with the side surfaces of the columns 41.

  In the connection structure of FIG. 9, the end faces of the horizontal member 53 and the oblique member 54 are in contact with the side surfaces of the column 41, and one adhesive 24 and 25 is attached to each of the horizontal member 53 and the oblique member 54. . In response to these, the indwelling devices 14 and 15 are attached to the side surfaces of the column 41 in a line up and down. Furthermore, the pair of indwelling devices 14 and 15 and the intimate-contact devices 24 and 25 are pulled up with a single bolt 31 both at the top and the bottom. Therefore, tool holes 47 are machined at two upper and lower positions on the side surface of the column 41. Besides, although the screw nail 60 used for connecting the column 41 and the horizontal member 53 is inserted along the longitudinal direction of the horizontal member 53, the screw nail 60 used for connecting the column 41 and the diagonal member 54 is the longitudinal direction of the diagonal member 54 Insert along, different angles on both sides.

  FIG. 10 shows details of the connection structure of FIG. The pillar 41 and the horizontal member 53 are integrated through the circular indwelling device 14 and the adhesion device 24. A central hole 37 for inserting a bolt 31 is formed at the center of the indwelling device 14, and nail holes 33 are formed at two upper and lower positions so as to sandwich the inner hole 37. It is A female screw 34 screwed to the bolt 31 is formed at the center of the adhesive tool 24. The nail holes 33 are formed at two upper and lower positions so as to sandwich the bolt 31. It is formed. Therefore, the screw nails 60 on the indwelling device 14 side and the adhesion device 24 side are aligned back to back in a straight line, and the two head parts are in contact with each other. Moreover, a shear load is transmitted by the convex part 35 and the recessed part 38 fitting.

  Next, the pillar 41 and the diagonal member 54 are integrated through the circular indwelling device 15 and the adhesion device 25. A central hole 37 for inserting a bolt 31 is formed at the center of the indwelling device 15, nail holes 33 are formed at two places on the left and right so as to sandwich the holes, and recesses 38 are formed at two upper and lower places. It is A female screw 34 screwed to the bolt 31 is formed at the center of the adhesion tool 25. Nail holes 33 are formed at two places on the left and right so as to sandwich the bolt 31. It is formed. In addition, the screw nail 60 used for connection of the pillar 41 and the diagonal member 54 is inserted along the longitudinal direction of the diagonal member. Therefore, each nail hole 33 has an intersecting angle with the surface of the indwelling device 15 and the adhesion device 25, but the screw nails 60 are aligned back to back in a straight line, and the points where both heads are in contact are the same as before. The point in which the convex part 35 and the concave part 38 fit is also the same as before.

  The screw nails 60 used for connecting the column 41 and the horizontal member 53 are inserted into the center line of the column 41. On the other hand, the screw nails 60 used for connecting the column 41 and the diagonal member 54 are inserted at positions left and right from the center line of the column 41. This is to prevent the screw nails 60 having different insertion directions from coming into contact with each other in the column 41 and to prevent the obliquely extending screw nails 60 from passing through the tool hole 47. Other than that, the points for pulling the indwelling devices 14 and 15 and the adhesion devices 24 and 25 with the bolt 31 are the same as in the past.

  FIG. 11 shows the case of constructing a bonding material in which two woods aligned in parallel are integrated by using the connection structure according to the present invention. The bonding material in this figure is obtained by bringing the side surfaces of the front rod 45 and the rear rod 55 of the same cross section into contact with each other and integrating them by the connection structure according to the present invention. Deploy. The indwelling device 16 and the intimate contact device 26 are rectangular extending vertically and are embedded in the holding grooves 46 and 56 formed on the contact surfaces of the front rod 45 and the rear rod 55 and attached with screws 60. Although six screw nails 60 are inserted into one indwelling device 16 and one intimate contact device 26, they are inserted obliquely to the contact surface of the front rod 45 and the rear rod 55 in order to prevent detachment. A tool hole 47 for tightening the bolt 31 is machined on the side of the front rod 45. In addition, in the screw nail 60, the front rod 45 side and the rear rod 55 side are aligned back to back in the same manner as in the previous drawings, and the heads of the both are in contact with each other.

  FIG. 12 shows details of the connection structure of FIG. Each of the indwelling device 16 and the adhesion device 26 used here is rectangular, and nail holes 33 are formed at six places. The nail hole 33 has an intersecting angle with the side surfaces of the front rod 45 and the rear rod 55, and has a configuration in which half of the directions are reversed and the screw nail 60 is inserted in a V shape, so that the pullout strength is excellent. Further, two bolts 31 are used for the pair of indwelling devices 16 and the adhesion devices 26, and four pairs of convex portions 35 and concave portions 38 are provided. Also in this connection structure, only the tool hole 47 is exposed to the outside, which is excellent in aesthetics.

  As shown in the drawings so far, the present invention can be used to connect all members constituting a wooden building, and the shapes of the indwelling device and the intimate contact device are free. Further, the screw nail 60 to which the indwelling device or the adhesion device is attached can be used freely or in the inserting direction as long as the head can be pressed by any means and the floating can be prevented. Similarly, as for the bolt 31 for drawing the indwelling device and the intimate contact device, if the whole is embedded inside and rotated from the tool hole 47 processed into one material, the number and use, etc. are free.
