[0002]

2. Description of the Related Art In recent years, for the purpose of labor saving and rationalization at the time of building a house or the like or improvement of the strength of a wooden building, beams and girders are provided by means of joints and fittings using joints, metal fittings, box hardware and the like. A joining structure and a joining method of structural members for joining columns, beams and trunks and through columns have been developed. Also, every year, including the Great Hanshin Earthquake, wooden houses are often severely damaged by earthquakes and typhoons, etc.In the joint structure of structural members of wooden buildings, including the improvement of joints such as joints etc. Various joining structures and joining methods of structural members aiming at improving the structural strength of the entire building have been developed. For example, Japanese Utility Model Application Laid-Open No. 63-1620
No. 08 (hereinafter referred to as “No. A”) is provided with a reinforcing plate having a through hole to which one end of the tambuckle braces is fastened,
And a plug fastening member comprising an L-shaped abutment plate having an appropriate number of rectangular shaft through-holes, and every other shaft through-hole of the L-shaped abutment plate of the member. A washer having two rectangular through-holes matching the holes, and an L-shaped abutment plate is buried in a plug hole provided in advance so as to be perpendicular to the abutting surface of the abutting member and the column member abutted. A square shaft protruding from the tip of the buried portion is fitted and fastened to a shaft through hole of the L-shaped contact plate of the L-shaped plug stopper and the washer stacked on the corresponding plate. The plug member and the plug nail hole of the buried portion of the buried plug member, from the plug nail guide hole communicating with the plug nail hole provided in advance on the side surface of the horizontal member or the pillar material. A timber fitting for a wooden building, which includes a nail to be nailed, is disclosed. Also, in Japanese Patent Application Laid-Open No. 9-41391 (hereinafter referred to as “B”), a wooden column embedding joint fitting is inserted from a column base of a wooden column into a buried hole formed to coincide with a coaxial center. From the through-holes formed in advance around the column bases of the wooden pillars so as to correspond to each through hole of the joint fitting such as the wooden pillar embedded,
Insert the fixing bolt, penetrate through each through hole of the joint fitting for embedding the wooden pole, protrude from the opposite side of the wooden pole, and fit the crosspiece receiving bracket to the tip side of the protruding fixing bolt After that, tighten the nuts, and fix the joints for the horizontal pillars and the wooden pillars to the pillars of the wooden pillars. A hand structure is disclosed. Furthermore, recently, the number of starts of wooden three-story houses has increased in urban areas with small sites, and due to the small size of the site and the need for a garage on the first floor, which requires a large frontage on the first floor. There are many. Below, 1
An example of a three-story house having a garage on the floor will be described with reference to the drawings. 15A is a plan view of the first floor of a three-storey house, FIG. 15B is a plan view of the second floor of a three-storey house, and FIG. FIG. In the drawing, 90a and 90b are columns, 91 is a load-bearing wall disposed between the columns 90b, 92 is a garage, and 92a is an open frontage of the garage 92. In the three-storey house shown in FIG.
Since two frontage portions 92a are required, the load bearing walls 91 cannot be arranged between the columns 90a as between the columns 90b, and the loads on the second and third floors are applied above the garage 92,
Conventionally, a large structural member has been used for the column 90a,
Only floors are reinforced.

[0003]

However, the above-mentioned conventional joining tools, joining structures and joining methods have the following problems. At the time of construction of a wooden building, it is necessary to attach metal fittings and hardware to structural members and fix them via bolts and nuts, etc., as well as lacking workability, the work at the time of construction is complicated and lacks workability, Further, the fixing force is reduced in several years due to the expansion and contraction of the wood, and the play is likely to be loose, and the reliability of the bonding strength is lacking. Since it requires physical strength such as bending, tension, compression, and shearing, metal fittings and hardware are large and heavy, and lack transportability.
In addition, safety is poor when working at heights. When the structural members made of wood are fixed with bolts and nuts, the tightening force is reduced in several years due to the expansion and contraction of the wood, and play is likely to occur, and the physical strength of the metal parts such as bolts, nuts, and hardware is oxidized And the reliability and durability are lacking. In addition, in the conventional joint structure, the strength of the wooden building is insufficient due to the pin joint, requiring bracing, structural plywood, steel braces, etc.
In addition, in the event of an earthquake or the like, the brace may be broken or dislodged and may not fulfill its original function, and thus has a problem of lack of reliability. Furthermore, in particular, the joining method using the joining tool disclosed in Japanese Patent Application Laid-Open Publication Nos. A and B-2002 has the following problems. In the wooden bracket for wooden construction of Japanese Patent Publication No. A, in order to embed the plug member, the plug member is previously communicated with the plug hole perpendicular to the contact surface between the horizontal member and the column member and the plug hole of the plug member. It is necessary to provide in advance a spigot guide hole to be provided on the side surface of the horizontal member or the column material. It is necessary to form a through hole corresponding to each through hole of the joint fitting for embedding a wooden pole in advance around the column base of the wooden pole, In any case, the workability of forming each hole is lacking, and the labor required to match the through hole formed in each fitting with the hole formed in each member such as a pillar is required, and the workability of joining structural members is lacking. Also, as shown in FIG.
In a conventional three-story house, since the garage 92 is provided on the first floor, a load-bearing wall cannot be arranged between the columns 90a, and the loads on the second and third floors are applied above the garage 92,
In the event of an earthquake or the like, there is a high possibility that the vehicle will be destroyed from the pillar 90a of the garage 92, and there is a problem that the vehicle lacks earthquake resistance and safety. In addition, the frontage 92a of the garage 92 is formed and the load bearing wall 9 is formed.
Because the building does not have the structure 1, the house is likely to shake due to the earthquake or the vibration of the second or third floor. In this case, there is a problem that the cross of the third floor wall may be distorted or broken. Was. Further, a large structural member may be used for the column 90a,
If only the floors have a reinforced structure, it takes time and effort to build the construction, and the construction workability is poor.

The present invention solves the above-mentioned conventional problems, and provides a joining tool having a simple structure, excellent joining workability, capable of remarkably shortening the construction period, and having high structural strength.
And, while being able to improve the structural strength of a wooden building, it can be added to an existing building or an earthquake-resistant reinforcement, and especially when the joint is used in combination with a joint, a particularly strong joint can be obtained. Even if one of the fittings and fittings is damaged by an earthquake, the building is not completely destroyed and has excellent seismic resistance and safety, and also has excellent safety during construction work and versatility The joining structure of the structural members, which can be easily and reliably joined even by unskilled persons with excellent joining strength, and the workability of construction can be significantly improved,
An object of the present invention is to provide a method for joining structural members, which simplifies the joining technique of structural members, reduces the number of work steps, and can significantly shorten the construction period.

[0005]

Means for Solving the Problems In order to solve the above-mentioned conventional problems, a joining tool according to the present invention, a joining structure of a structural member using the joining tool, and a joining method of a structural member have the following configurations. The connector according to claim 1 of the present invention,
a. A rod-shaped body, b. A sharp end formed at one end of the body, or a tip having a threaded portion on its surface,
c. A swelling shape, a flat shape, a nut shape, and a punched portion formed at the other end of the body portion and having a swelling surface or a flat surface at the end surface thereof, or a cutting portion or a protruding portion such as a +,-, or hexagonal shape. A head having a fastening portion having an inverted frustum shape or the like; d. A hollow portion formed substantially in the longitudinal direction of the axis of the body, e. An inlet for an adhesive that communicates with the hollow portion from the end face of the head,
f. And a discharge port for one or a plurality of adhesives drilled from the outer peripheral surface of the trunk portion to communicate with the hollow portion.

Thus, the following operation is obtained. a. When joining between wood and glulam, or between wood and glulam, or between wood and stone, concrete, and other members, form an insertion section with a depth shorter than the length of the joint in the joining member. The members can be joined to each other simply by inserting the joining tool into the insertion section and driving or screwing the tip end of the joining tool to the bottom of the insertion section. b. Since the connector has a hollow portion in the longitudinal direction and has a discharge port for adhesive drilled in communication with the hollow portion, the adhesive is injected from the injection port into the hollow portion to discharge the adhesive from the discharge port. The adhesive can be filled between the outer peripheral surface of the joining tool and the peripheral wall of the insertion portion of the member into which the joining tool has been inserted, and the members can be tightly joined to each other for rigid joining. c. When joining members using a plurality of the joining tools,
It is possible to reduce the outer diameter of the body portion or the like of the joining tool, thereby reducing the loss of the cross section of the member and preventing the member from decreasing in strength. d. Since a connector made of a metal or other high-strength member is buried and fixed with an adhesive in an insertion portion into which the connector formed in the member is inserted, a high-shear, high-tension rigid connection can be maintained. e. After joining the members with joining metal fittings such as U-shaped box hardware and hook-shaped metal fittings, insert the joining tool into the insertion section formed on each member, and strike the tip of the joining tool at the bottom of the insertion section. Since the members can be tightly fixed by joining or screwing and injecting an adhesive into the hollow portion of the joint, the members can be accurately joined after the members are temporarily fixed with the joint metal, and the members can be properly fixed. The contact surfaces can be brought into close contact with each other to prevent the adhesive from leaking, and in addition to the joining metal fitting, the joining strength such as shearing and tension between the members can be maintained by the joining tool. f. When the distal end portion has a threaded portion, the connector can be inserted into the insertion portion of the member and the distal end portion can be screwed into the bottom portion of the insertion portion. Can be prevented from leaking from the contact surfaces of the members, and the members can be securely adhered to each other and joined even when the joining metal fitting is not used for joining the members.

Here, the body of the connector may be formed in a substantially elliptical shape, a triangular shape, a quadrangle shape, a hexagonal shape or the like in addition to a circular cross section. As the distal end of the connector, one having a sharp end is used, and in particular, when there is no screw-like portion on the sharp surface, it has a polygonal pyramid shape such as a conical shape or a nail point shape. It is formed. If the head of the connector has a screw-shaped portion at the tip, a +
, Swelling, flat, nut-shaped, inverted frustum-shaped, etc. with cutting parts such as,-, hexagonal, etc., and a screw-shaped part at the tip In the case where it is not used, the one having a driving portion formed of a swelling surface or a flat surface on the end surface is used.

The outer diameter of the head is 1.2 times to 2.5 times, preferably 1.5 times to 2 times the outer diameter of the torso.
Formed twice. Thereby, when the adhesive is injected into the hollow portion and filled between the outer peripheral surface of the joint and the peripheral wall of the insertion portion of the member into which the joint is inserted, the adhesive overflows from the head side. Can be prevented. As the outer diameter of the head becomes smaller than 1.5 times the outer diameter of the torso, the adhesive tends to overflow from the side of the head, and the outer diameter of the head becomes larger than twice the outer diameter of the torso. As the size increases, the head tends to protrude greatly from the member, which is not preferable. Further, as a material of the joining tool, in addition to iron products such as stainless steel, chromium, steel, and carbon steel, and metals such as aluminum alloys, organic and inorganic fibers such as carbon fiber, boron fiber, glass fiber, and metal fiber. And what was processed with synthetic resin is used.

[0009] The discharge port and the injection port of the adhesive communicating with the hollow portion of the connector are about 1/20 to 16/20 times, preferably about 1/20 times the outer diameter of the body of the connector. 10 times ~
A cross section having a diameter 5/10 times as large is formed in a substantially circular shape. In addition, depending on the viscosity of the adhesive and the material of the connector, as the diameter becomes smaller than 1/10 times the outer diameter of the body of the connector, the flow of the adhesive in the hollow portion is lacking as the diameter becomes smaller than 1/10. And the mechanical strength of the connector tends to be impaired as the ratio becomes larger than 5/10 times, which is not preferable. One or more discharge ports are formed so as to communicate with the hollow part and penetrate in the diameter direction of the body part of the connector. When a plurality are formed, they may be formed substantially radially around the hollow portion. This is because the injection time can be shortened. Also, if formed at a symmetrical position from the hollow part,
It is preferable because the adhesive injected into the hollow portion can be almost uniformly discharged to the outer peripheral surface of the joining tool, and uneven filling of the adhesive can be prevented. In addition, as for the formation position of the discharge port, when the connector is inserted obliquely downward from the upper surface of the member, the discharge port is formed at the tip end side of the body of the connector, and the connector is positioned above the lower surface of the member. When the connector is inserted obliquely, it is preferable to form the discharge port on the head side of the body of the connector. Thereby, the adhesive can be evenly filled between the outer peripheral surface of the joint and the peripheral wall of the insertion portion of the member into which the joint is inserted.

According to a second aspect of the present invention, there is provided the connector according to the first aspect, wherein the distal end portion protrudes from one end surface of the body portion coaxially with the body portion and is fixed or detachable. The protruding portion is provided coaxially with the body, and has a configuration in which the maximum outer diameter of the tip is smaller than the outer diameter of the body.

Thus, the following operation is obtained in addition to the operation of the first aspect. g. Since the maximum outer diameter of the distal end portion is formed smaller than the outer diameter of the trunk portion (the distal end portion has a trunk portion and a sharp portion, and the maximum outer diameter of the trunk portion is formed smaller than the trunk portion of the joining tool). When the insertion portion for inserting the connector is formed on the surface side of the member, or when the connector is obliquely inserted into the insertion portion of the member, the surface of the member (outer peripheral wall surface) is formed by the distal end of the connector. Cracks and the like can be prevented from being generated. h. Since the tip portion is formed thinner than the body portion, when the joining tool is driven or screwed into the glued laminated lumber, the force by which the tip portion pushes out the member can be reduced, and a thin veneer called lamina When the glued laminated lumber produced by laminating the laminated materials is joined with the joining tool, it is possible to prevent the lamina on the surface of the glued laminated wood from peeling off, partially rising or cracking. i. When the distal end is detachably protruded from the body, the distal end can be replaced with a distal end having a different length or material depending on the material or the like of the member, and the usability and versatility of the connector can be improved.

Here, the tip portion may be formed in a polygonal pyramid shape such as a conical shape or a nail point shape from the base side (body portion side) to the end portion side, or may have a circular or polygonal cross section on the base side. It has a torso shape, only the end is formed in a sharp shape such as a polygonal pyramid such as a cone or a nail, or only the end side surface or the entire surface is formed in a screw shape Things etc. are used.
In addition, when the tip portion is detachably protruded from the body portion, a female screw portion is formed on one end surface of the body portion, and a male screw portion is formed on the base side of the tip portion,
A fitting recess into which the base side of the tip is fitted is formed on one end surface of the body, and the tip is removably protruded from the body by screwing, fitting, or the like. The material of the tip may be the same as or different from the body. The diameter (maximum outer diameter) on the base side of the distal end is 3 mm to 8 mm, preferably 4 mm to 7 mm. Depending on the material of the distal end and the member to be joined with the connector, as the diameter of the base of the distal end becomes smaller than 4 mm, the distal end lacks strength and the durability of the connector is easily reduced. There is a tendency, 7m
As the value becomes larger than m, the surface of the member tends to crack when the connector is driven or screwed into the member, and both are not preferable.

According to a third aspect of the present invention, there is provided the joint according to the first or second aspect, wherein the body has the head at one end and a joint at the other end. It has a configuration including a member, one or more trunk members having trunk junctions at both ends, and a tip member having a junction at one end and the tip at the other end.

Thus, in addition to the function of claim 1 or 2, the following function is provided. j. The joining member can be formed by joining and connecting the head member, the trunk member, and the tip member in order at each joint, and the length of the joining member can be arbitrarily changed according to the number of the trunk members to be joined. can do. k. In particular, when the discharge port is formed on the distal end side of the joint, a hollow portion is formed in each of the head member, the body member, and the distal member, and the discharge port communicating with the hollow portion of the distal member is formed in the distal member. Can be formed, and the hollow portion of the connector can be divided and formed, so that the forming distance of the hollow portion can be shortened, and even when a discharge port is required on the tip end side of the connector, the hollow portion or The discharge port can be easily formed.

Here, the joints and the body joints are formed in such a manner that each member can be detachably joined, such as those having a male screw portion or a female screw portion, those having a fitting concave portion or a fitting convex portion. Is used. Further, the joint member may be formed by joining the head member and the tip member at each joint. In each member, a hollow portion that is substantially straight in the length direction when the members are connected is formed up to the discharge port. Furthermore, when the discharge port formed in the body portion is formed on the tip end side, the forming distance of the hollow portion is long, and when the hollow portion is too long, it is impossible to form the hollow portion, In the case where the discharge port is formed on the distal end portion side, the connector divided into a head member, a body member, and a distal member is preferably used.

According to a fourth aspect of the present invention, there is provided the connector according to any one of the first to third aspects, wherein a spiral member such as a spring externally fitted to the body is provided.
Alternatively, a configuration is provided in which the head side end of the trunk has a neck formed with an outer diameter larger than the outer diameter of the trunk and equal to or smaller than the outer diameter of the head.

Accordingly, the following functions are provided in addition to the functions of the first to third aspects. l. When a helical member such as a spring is externally fitted to the body of the connector, when the adhesive is injected into the hollow portion of the connector, the adhesive discharged from the discharge port of the connector is applied to the outer peripheral surface of the connector and It is possible to fill almost evenly along the spiral member between the peripheral walls of the insertion part of the member in which the connector is inserted, to prevent short paths and prevent uneven filling, so that adhesives with high viscosity can be easily used. Can be used to bind members. m. Since the spiral member is externally fitted to the body of the connector, the spiral member is buried with an adhesive, and the connector functions as a reinforcing material, and the shearing and tensile stress at the joint between the members is reduced. The durability can be improved. n. When a neck formed with an outer diameter larger than the outer diameter of the torso and equal to or smaller than the outer diameter of the head is provided, substantially uniform between the insertion portion of the member into which the jig is inserted and the torso of the jig. A gap can be secured, and the gap between the outer peripheral surface of the body and the peripheral wall of the insertion portion into which the body is inserted can be substantially uniformly filled with the adhesive discharged from the discharge port formed in the body. it can. o. In particular, when the outer diameter of the insertion portion for inserting the connector and the outer diameter of the neck portion are made substantially the same, the adhesive filled between the outer peripheral surface of the trunk portion and the peripheral wall of the insertion portion of the member into which the connector is inserted has the head side. Can be prevented from overflowing.

Here, the neck is formed to have a diameter 3 mm to 15 mm, preferably 5 mm to 12 mm larger than the diameter of the body of the connector. As the difference between the diameter of the neck and the diameter of the body becomes smaller than 5 mm, the gap between the body of the joint and the peripheral wall of the insertion part where the joint is inserted becomes smaller, and especially when high viscosity adhesive is injected. As the difference between the diameter of the neck and the diameter of the body becomes larger than 12 mm, the gap between the body of the joint and the peripheral wall of the insertion part into which the joint is inserted becomes too large. Tends to unnecessarily increase the amount used, and none of them is preferable.

According to a fifth aspect of the present invention, there is provided the connector according to any one of the first to fourth aspects, wherein the sealing body having a projection fitted into the inlet is provided. It has a configuration provided.

Accordingly, the following functions are provided in addition to the functions of the first to fourth aspects. p. After injecting the adhesive from the injection port into the hollow part, the projection can be fitted into the injection port to seal the injection port, and adhesives with extremely low viscosity or adhesives that take a long time to cure Even when used, the adhesive can be prevented from leaking from the injection port, and the appearance of the head of the connector can be improved.

Here, it is sufficient that the sealing body has a projection that can be fitted into the injection port, and has a shape that covers the head of the joint, or covers the head of the joint. A member formed flush with the surface of the member into which the connector is inserted is used.

According to a sixth aspect of the present invention, there is provided a joining structure for a structural member, wherein the joining member according to any one of the first to fifth aspects is brought into contact with a joint at a predetermined contact surface. Two or more structural members, such as a structural member and a vertical structural member, and the outer peripheral wall portion of the structural member having a perpendicular or predetermined inclination angle with respect to the abutting surface and communicating with the other structural members to form the joint; One or more connector inserts drilled at a depth shorter than the length of the fixture;
An adhesive which is injected into a hollow portion of the connector and is discharged from a discharge port of the connector and is filled between an outer peripheral surface of the connector and a peripheral wall of the connector insertion portion. I have.

As a result, the following operation is obtained. a. By inserting the connector into the connector insertion portion formed on the structural member and driving or screwing the distal end portion of the connector to the bottom of the connector insertion portion, the structural members can be joined to each other. b. By injecting the adhesive into the hollow portion of the joint, the adhesive is discharged from the discharge port of the joint, and the adhesive is filled between the outer peripheral surface of the joint and the peripheral wall of the joint insertion portion to form the structural members. Can be consolidated. c. Since the connector having extremely high mechanical strength is embedded in each structural member to tightly connect the structural members, the resistance of the structural member to bending, tension, compression, shearing, and the like can be improved. d. When the connector is inserted with a predetermined inclination angle with respect to the contact surface of the structural member, it can withstand deformation due to a vertical load, and the rigidity of the structural members can be improved. e. Inserting the connector into the connector insertion part formed in a cross shape between the structural members can hold the structural member simply by inserting it, and furthermore, if the connector is fixed and injected with adhesive, extremely high mechanical strength Excellent bonding can be enabled. f. Since the joining tool is embedded in the structural member and the outer peripheral surface of the joining tool is covered with the adhesive, it is possible to prevent the joining tool from being oxidized and the like, and to improve the durability of the joining tool. g. The structural members are joined by driving or screwing the joints to the structural members, and furthermore, an adhesive is filled between the outer peripheral surface of the joints and the peripheral wall of the joint insertion portion to tighten the structural members together. Therefore, the structural members can be rigidly joined to each other, so that the joining strength can be improved. In addition, since the structural members are tied with an adhesive, expansion and contraction of the structural members such as wood can be absorbed and rattling can be prevented. h. Since the joints between the structural members have a rigid frame structure that is firmly joined with a joint and an adhesive, the frontage (span) of the building can be significantly expanded without using load-bearing walls or braces, and there are no columns You can get space.

Here, the length of the connector insertion portion is preferably formed to be at least substantially the same as the body of the connector. When the discharge port of the adhesive is formed on the tip end side of the body, it is formed at least at a depth where the discharge port is not buried. As the length becomes shorter (shallower) than the length of the body of the connector, the length of driving or screwing the tip to the bottom of the connector insertion part tends to be longer, and the workability tends to decrease, and the adhesive is filled. There is a tendency that the volume between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion becomes smaller and the binding force by the adhesive decreases, and the bottom of the connector insertion portion is pushed open by the body by the connector. Surface of the structural member (outer peripheral wall)
Cracks and the like tend to occur. Further, as the length becomes longer (deeper) than the length of the body portion of the connector, the length of the tip portion of the connector that can be driven or screwed to the bottom of the connector insertion portion becomes shorter, and the fixing force by the connector decreases. There is a tendency, none of them is preferable. The connector insertion portion is formed at a position 1.1 to 6 times the outer diameter of the body or neck of the connector inside the outer peripheral wall surface of the structural member, depending on the size of the structural member. When a large external force is applied to the structural member at a position smaller than 1.1 times the outer diameter of the body or neck of the joint from the outer peripheral wall surface of the structural member, the end of the structural member tends to be damaged. As the size increases, the number of connector insertion portions that can be formed in the structural member decreases, and it tends to be difficult to improve the joining force between the structural members.

The size of the connector insertion part is 3 mm to 15 mm, preferably 5 mm to 5 mm, based on the outer diameter of the body of the connector.
It is formed 12 mm larger. As the difference between the outer diameter of the connector insertion portion and the outer diameter of the body of the connector becomes smaller than 5 mm, the adhesive discharged from the discharge port is bonded depending on the type of the adhesive and the construction time (summer and winter). There is a tendency that it is difficult to flow between the outer peripheral surface of the body of the fitting and the peripheral wall of the fitting insertion part, and as the difference from the outer diameter of the body of the fitting becomes larger than 12 mm, there is a tendency to require more adhesive than necessary. And both are not preferred.
If the connector has a neck, it is preferable that the size of the connector insertion portion be substantially the same as the neck. As it becomes smaller than the neck of the connector, it becomes more difficult to insert the neck of the connector into the connector insertion portion, and as the diameter becomes 1.5 times or more the neck of the connector, the torso portion of the connector and the peripheral wall of the connector insertion portion. There is a tendency that the adhesive filled in between leaks from the head side of the connector, which is not preferable. When the inner diameter of the connector insertion portion is larger than the outer diameter of the neck portion, leakage of the adhesive can be prevented by using a washer. Furthermore, the connector insertion portion is formed in an arbitrary cross-sectional shape such as a circle, an ellipse, a polygon such as a square or a hexagon.

Further, when the structural member is applied with a particularly large external force at its tip, such as a horizontal cantilever, it is preferable to form the connector insertion portion with an inclination angle α. Is 20 ° ≦ α <90 ° with respect to the contact surface
Preferably 20 ° ≦ α ≦ 70 °, more preferably 30 °
≦ α ≦ 60 °. As the inclination angle becomes smaller than 30 °, the position of the connector insertion portion approaches the end of the structural member, and the structural member tends to be easily damaged by a large external force, and the inclination angle becomes larger than 60 °. As the length of the connector becomes too long, the workability tends to decrease, which is not preferable. In particular, when the connector insertion portion is formed from the upper outer peripheral wall side of the structural member, the connector can be inserted from above the structural member and easily driven or screwed to the bottom of the connector insertion portion. Not only can the head of the joint be exposed at the lower outer peripheral wall of the structural member, but also the appearance can be improved, and the outer peripheral surface of the joint and the peripheral wall of the joint insertion portion can be reliably inserted. It has the effect that the adhesive can be filled. In addition, another connector insertion portion is perforated so as to be cross-shaped with the connector insertion portion at a predetermined interval on the contact surface of the structural member to be joined, and the connector is inserted into each connector insertion portion. When the members are joined, loads from the top, bottom, left and right, such as tension, bending, and shearing, of the joined structural members can be canceled out by couples of the joining members, and the joining force between the structural members can be improved. Further, by forming the connector insertion portion with an inclination angle α or forming a cross shape, the connector can be used even in the case of a two-way rigid frame structure or when there are structural members in three or four directions. It has the effect that members can be joined together. As the adhesive, an epoxy resin adhesive, a polyurethane adhesive, a vinyl acetate resin adhesive, or the like is used.

According to a seventh aspect of the present invention, there is provided the joint structure for a structural member according to the sixth aspect of the present invention, wherein one of the outer peripheral walls of the structural member is provided between the abutted structural members. It has a structure provided with one or more air vents perforated in communication with the connector insertion part.

However, the above-mentioned conventional joining tool, joining apparatus and joining method have the following problems. At the time of construction of wooden buildings, metal fittings and hardware etc. must be attached to pillars, beams, girders, etc. and fixed to them with bolts and nuts, etc.In addition to lacking workability, work at the time of construction is complicated In addition, the elasticity of the wood is reduced, and the fixing force is reduced in several years due to the expansion and contraction of the wood. Since physical strength such as bending, tension, compression, and shearing is required, metal fittings and hardware are large and heavy, and lack transportability, and lack safety when working at heights. Made of wood
When structural members such as columns, beams, and girders are fixed together with bolts and nuts, the tightening force is reduced in several years due to the expansion and contraction of wood, which tends to cause play, and oxidation of metal parts such as bolts, nuts, and hardware. As a result, physical strength is reduced, and reliability and durability are lacking. In addition, the conventional joining device has insufficient strength of a wooden building due to pin joining, and requires bracing, structural plywood, steel braces, and the like. In some cases, the original function may not be fulfilled, and there is a problem of lack of reliability. Further, in particular, in the joining method using the joining tool of JP-B or JP-B,

It is necessary to form a through hole corresponding to each through hole of the joint fitting for embedding a wooden column in advance around the column base of the wooden column, so that In each case, the workability of forming each hole is lacking, and it requires time and effort to match the through hole formed in each bracket with the hole formed in each member such as a column member, and the joining work of columns, beams, girders, etc. Lack of sex. In a conventional three-story house as shown in FIG.
Since the garage 92 is provided on the floor, a load-bearing wall cannot be arranged between the columns 90a, and two garages 92 are provided above the garage 92.
There is a high possibility that the load will be applied to the third and third floors, and in the event of an earthquake or the like, the pillars 90a of the garage 92 are likely to be destroyed, and there is a problem of lack of earthquake resistance and safety. In addition, since the frontage 92a of the garage 92 is formed and the bearing wall 91 is not provided, the house is easily shaken by the earthquake or the vibration of the second or third floor. In this case, especially, the cross of the third floor wall is distorted or broken. Or there is a possibility that the Furthermore, when a large-sized structural member is used for the column 90a or when only the first floor is made to have a reinforced structure, there is a problem that it takes time and effort to build the building, lacks building workability, and raises the cost.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, a connector according to the present invention and a column using the same ,
Beam bonding apparatus and columns of digits or the like, beams, bonding method digits, etc.,
It has the following configuration. The connector according to claim 1 of the present invention comprises: a. A rod-shaped body, b. A sharp end formed at one end of the body, or a tip having a threaded portion on its surface; c. A swelling shape, a flat shape, a nut shape, and a punched portion formed at the other end of the body portion and having a swelling surface or a flat surface at the end surface thereof, or a cutting portion or a protruding portion such as a +,-, or hexagonal shape. A head having a fastening portion having an inverted frustum shape or the like; d. A hollow portion formed substantially in the longitudinal direction of the axis of the body, e. An injection port for an adhesive communicating from the end face of the head to the hollow portion; f. An outlet for one or more adhesives drilled from the outer peripheral surface of the body to communicate with the hollow; g. The torso
A helical member such as a spring externally fitted to and / or
The outer diameter of the trunk is larger than the outer diameter of the trunk at the head side end of the trunk.
And formed with an outer diameter equal to or smaller than the outer diameter of the head.
And a broken neck portion .

Thus, the following operation is obtained. a. When joining between wood and glulam, or between wood and glulam, or between wood and stone, concrete, and other members, form an insertion section with a depth shorter than the length of the joint in the joining member. The members can be joined to each other simply by inserting the joining tool into the insertion section and driving or screwing the tip end of the joining tool to the bottom of the insertion section. b. Since the connector has a hollow portion in the longitudinal direction and has a discharge port for adhesive drilled in communication with the hollow portion, the adhesive is injected from the injection port into the hollow portion to discharge the adhesive from the discharge port. The adhesive can be filled between the outer peripheral surface of the joining tool and the peripheral wall of the insertion portion of the member into which the joining tool has been inserted, and the members can be tightly joined to each other for rigid joining. c. When joining members using a plurality of the joining tools,
It is possible to reduce the outer diameter of the body portion or the like of the joining tool, thereby reducing the loss of the cross section of the member and preventing the member from decreasing in strength. d. Since a connector made of a metal or other high-strength member is buried and fixed with an adhesive in an insertion portion into which the connector formed in the member is inserted, a high-shear, high-tension rigid connection can be maintained. e. After joining the members with joining metal fittings such as U-shaped box hardware and hook-shaped metal fittings, insert the joining tool into the insertion section formed on each member, and strike the tip of the joining tool at the bottom of the insertion section. Since the members can be tightly fixed by joining or screwing and injecting an adhesive into the hollow portion of the joint, the members can be accurately joined after the members are temporarily fixed with the joint metal, and the members can be properly fixed. The contact surfaces can be brought into close contact with each other to prevent the adhesive from leaking, and in addition to the joining metal fitting, the joining strength such as shearing and tension between the members can be maintained by the joining tool. f. When the distal end portion has a threaded portion, the connector can be inserted into the insertion portion of the member and the distal end portion can be screwed into the bottom portion of the insertion portion. Can be prevented from leaking from the contact surfaces of the members, and the members can be securely adhered to each other and joined even when the joining metal fitting is not used for joining the members. g. Spiral members such as springs are fitted onto the body of the connector
When the adhesive is injected into the hollow part of the
The adhesive discharged from the discharge port of the fixture is applied to the outer peripheral surface of the joint and
Spiral member between the peripheral walls of the insertion portion of the member into which the connector has been inserted
Almost evenly along the
Can prevent the occurrence of
Adhesive can also be used easily, and members can be tied together. h. Since the spiral member is fitted over the body of the connector,
The spiral member is buried with the adhesive, and the joint is used as a reinforcing material.
Plays a role, shearing, tensile stress, etc. at the joint of members
And the durability can be improved. i. Be larger than the outside diameter of the torso and the same as the outside diameter of the head
With a neck formed with a small outer diameter,
A substantially uniform gap between the inserted part of the inserted member and the body of the connector
Between the discharge ports formed in the body
Insert the discharged adhesive with the outer peripheral surface of the body and the body inserted.
The gap between the peripheral walls of the entry portion can be substantially uniformly filled. j. In particular, the outer diameter of the insertion part where the connector is inserted and the outer diameter of the neck are approximately the same.
If the same, the outer peripheral surface of the body and the member into which the connector is inserted
Adhesive filled between the peripheral walls of the insertion part overflows to the head side
Can be prevented.

Here, the body of the connector may be formed in a substantially elliptical shape, a triangular shape, a quadrangle shape, a hexagonal shape or the like in addition to a circular cross section. As the distal end of the connector, one having a sharp end is used, and in particular, when there is no screw-like portion on the sharp surface, it has a polygonal pyramid shape such as a conical shape or a nail point shape. It is formed. If the head of the connector has a screw-shaped portion at the tip, a +
, Swelling, flat, nut-shaped, inverted frustum-shaped, etc. with cutting parts such as,-, hexagonal, etc., and a screw-shaped part at the tip In the case where it is not used, the one having a driving portion formed of a swelling surface or a flat surface on the end surface is used.

The outer diameter of the head is 1.2 times to 2.5 times, preferably 1.5 times to 2 times the outer diameter of the torso.
Formed twice. Thereby, when the adhesive is injected into the hollow portion and filled between the outer peripheral surface of the joint and the peripheral wall of the insertion portion of the member into which the joint is inserted, the adhesive overflows from the head side. Can be prevented. As the outer diameter of the head becomes smaller than 1.5 times the outer diameter of the torso, the adhesive tends to overflow from the side of the head, and the outer diameter of the head becomes larger than twice the outer diameter of the torso. As the size increases, the head tends to protrude greatly from the member, which is not preferable. Further, as a material of the joining tool, in addition to iron products such as stainless steel, chromium, steel, and carbon steel, and metals such as aluminum alloys, organic and inorganic fibers such as carbon fiber, boron fiber, glass fiber, and metal fiber. And what was processed with synthetic resin is used.

[0009] The discharge port and the injection port of the adhesive communicating with the hollow portion of the connector are about 1/20 to 16/20 times, preferably about 1/20 times the outer diameter of the body of the connector. 10 times ~
A cross section having a diameter 5/10 times as large is formed in a substantially circular shape. In addition, depending on the viscosity of the adhesive and the material of the connector, as the diameter becomes smaller than 1/10 times the outer diameter of the body of the connector, the flow of the adhesive in the hollow portion is lacking as the diameter becomes smaller than 1/10. And the mechanical strength of the connector tends to be impaired as the ratio becomes larger than 5/10 times, which is not preferable. One or more discharge ports are formed so as to communicate with the hollow part and penetrate in the diameter direction of the body part of the connector. When a plurality are formed, they may be formed substantially radially around the hollow portion. This is because the injection time can be shortened. Also, if formed at a symmetrical position from the hollow part,
It is preferable because the adhesive injected into the hollow portion can be almost uniformly discharged to the outer peripheral surface of the joining tool, and uneven filling of the adhesive can be prevented. In addition, as for the formation position of the discharge port, when the connector is inserted obliquely downward from the upper surface of the member, the discharge port is formed at the tip end side of the body of the connector, and the connector is positioned above the lower surface of the member. When the connector is inserted obliquely, it is preferable to form the discharge port on the head side of the body of the connector. Thereby, the adhesive can be evenly filled between the outer peripheral surface of the joint and the peripheral wall of the insertion portion of the member into which the joint is inserted.

[0010] The neck portion of the connector is directly connected to the body of the connector.
3 mm to 15 mm, preferably 5 mm to 12 mm larger than the diameter
It is formed with a critical diameter. The difference between the neck diameter and the body diameter
Insert the torso of the joint and the joint as it becomes smaller than 5 mm
The gap between the peripheral walls of the inserted part becomes smaller,
Adhesive tends to be difficult to flow when high adhesive is injected
And the difference between the neck diameter and the torso diameter is greater than 12 mm
As it becomes easier, the torso of the connector and the insertion part where the connector is inserted
The gap between the peripheral walls of the wall becomes too large and requires the use of adhesive
There is a tendency to increase more than that, and neither is preferable.

[0011] bonding tool according to claim 2 of the present invention is the invention according to claim 1, wherein the distal end the body portion coaxially on one end surface of the barrel projecting fixed or removably It is configured to protrude coaxially with the body, and has a configuration in which the maximum outer diameter of the tip is smaller than the outer diameter of the body.

Thus, the following operation is obtained in addition to the operation of the first aspect . k . Since the maximum outer diameter of the distal end portion is formed smaller than the outer diameter of the trunk portion (the distal end portion has a trunk portion and a sharp portion, and the maximum outer diameter of the trunk portion is formed smaller than the trunk portion of the joining tool). When the insertion portion for inserting the connector is formed on the surface side of the member, or when the connector is obliquely inserted into the insertion portion of the member, the surface of the member (outer peripheral wall surface) is formed by the distal end of the connector. Cracks and the like can be prevented from being generated. l . Since the tip portion is formed thinner than the body portion, when the joining tool is driven or screwed into the glued laminated lumber, the force by which the tip portion pushes out the member can be reduced, and a thin veneer called lamina When the glued laminated lumber produced by laminating the laminated materials is joined with the joining tool, it is possible to prevent the lamina on the surface of the glued laminated wood from peeling off, partially rising or cracking. m . When the distal end is detachably protruded from the body, the distal end can be replaced with a distal end having a different length or material depending on the material or the like of the member, and the usability and versatility of the connector can be improved.

[0013] Here, the tip, which is formed on the base side conically toward the end portion side from the (body side) and a nail destination shaped like a pyramid-shaped and, in the proximal section is circular or polygonal It has a torso shape, only the end is formed in a sharp shape such as a polygonal pyramid such as a cone or a nail, or only the end side surface or the entire surface is formed in a screw shape The thing etc. are used.
In addition, when the tip portion is detachably protruded from the body portion, a female screw portion is formed on one end surface of the body portion, and a male screw portion is formed on the base side of the tip portion,
A fitting recess into which the base side of the tip is fitted is formed on one end surface of the body, and the tip is removably protruded from the body by screwing, fitting, or the like. The material of the tip may be the same as or different from the body. The diameter (maximum outer diameter) on the base side of the distal end is 3 mm to 8 mm, preferably 4 mm to 7 mm. Depending on the material of the distal end and the member to be joined with the connector, as the diameter of the base of the distal end becomes smaller than 4 mm, the distal end lacks strength and the durability of the connector is easily reduced. There is a tendency, 7m
As the value becomes larger than m, the surface of the member tends to crack when the connector is driven or screwed into the member, and both are not preferable.

[0014] bonding tool according to claim 3 of the present invention is the invention according to claim 1 or 2, wherein the body portion, a head-side cylinder member having a joint portion at the opposite end of the head has a one or more intermediate portions body member having a body joint at both ends, and a tip-side barrel member having a joint portion at the opposite end of the tip, a configuration with a.

[0015] Thus, in addition to the operation of claim 1 or 2, having the following effects. n . Head side cylinder member and the intermediate portion body member, it is possible to form the bonding tool by connecting by joining distal portion side body member sequentially in each joint, and the number of the intermediate portion body member to be joined Thus, the length of the connector can be arbitrarily changed. o . In particular, if the discharge port is formed in the front end portion of the該接Gogu, head side cylinder member and the intermediate portion body member, to form a hollow portion in each of the distal end side barrel member distal end side barrel member of the discharge port which communicates with the hollow portion can be formed on the distal end side body portion material, it is possible to form by dividing the hollow portion of該接Gogu, can shorten the forming distance of the hollow portion, connectors Even when a discharge port is required at the tip end side, a hollow portion and a discharge port can be easily formed.

[0016] Here, as the bonding portion and the body joint, which was formed a male screw portion or a female thread portion, such as those forming the fitting recess or fitting projection, shaped respective members can be joined detachably Is used. Also, the head side trunk member and the tip side
A body member may be formed the bonding tool by bonding at each junction. In each member, a hollow portion that is substantially straight in the length direction when the members are connected is formed up to the discharge port. Furthermore, when the discharge port formed in the body is formed on the tip end side, the forming distance of the hollow portion is long, and when the hollow portion is too long, it is impossible to form the hollow portion, If the discharge port is formed on the tip side, head side cylinder member, medium
During unit body member, it divided the joint member is preferably used in the front end portion side body member.

The bonding tool according to claim 4 is the invention according to any one of claims 1 to 3, the sealing body having a projection to be fitted into the inlet It has a configuration provided.

[0018] Thus, in addition to the operation of claims 1 to 3, it has the effect of following. p. After injecting the adhesive from the injection port into the hollow part, the projection can be fitted into the injection port to seal the injection port, and adhesives with extremely low viscosity or adhesives that take a long time to cure Even when used, the adhesive can be prevented from leaking from the injection port, and the appearance of the head of the connector can be improved.

[0019] As the sealing member needs to have a protrusion that can fit in the inlet, one or shaped to Kutsugae設the head of the connectors, the head of the connectors Kutsugae設A member formed flush with the surface of the member into which the connector is inserted is used.

The bonding apparatus of columns, beams, digits, etc. according to claim 5 of the present invention comprises a bonding tool according to any one of claims 1 to 4, the contact at a predetermined contact surface Two or more structural members such as pillars, beams, girders, etc. , and communicate with the other structural members from the outer peripheral wall of the structural member at a right angle or a predetermined inclination angle with respect to the contact surface. One or more jig insertion portions perforated at a depth shorter than the length of the jig, and the outer peripheral surface of the jig being injected into the hollow portion of the jig and discharged from the discharge port of the jig, and And an adhesive filled between the peripheral walls of the tool insertion portion.

[0021] As a result, the following effects can be obtained. a. By inserting the connector into the connector insertion part formed on the pillar, beam, girder, etc. , and driving or screwing the tip of the connector into the bottom of the connector insertion part, the column, beam, girder, etc. it can be joined to structural members each other. b. By injecting the adhesive into the hollow portion of the joint, the adhesive is discharged from the discharge port of the joint, and the adhesive is filled between the outer peripheral surface of the joint and the peripheral wall of the joint insertion portion, and the column, the beam, and the like. , Digits, etc.
It is possible to consolidate the structural members to each other for. c. Because the joints with extremely high mechanical strength are embedded in each structural member such as columns, beams, girders, etc., and the structural members are tightly connected,
The resistance of the structural member to bending, tension, compression, shear, and the like can be improved. d. When the connector is inserted at a predetermined inclination angle with respect to a contact surface of a structural member such as a column, a beam, or a girder , it can withstand deformation due to a vertical load, and the rigidity of the structural members can be improved. e. Inserting a connector into a connector insertion part formed in a cross shape between structural members such as columns, beams, girders, etc., can hold the structural member just by inserting, further fixing the connector and applying adhesive. Injection can enable bonding with extremely high mechanical strength. f. The joints are buried in columns, beams, girders, etc.
Since the outer peripheral surface of the joint is covered with the adhesive, it is possible to prevent the joint from being oxidized and the like, and to improve the durability of the joint. g. The structural member such as a pillar, a beam, or a girder is cast or screwed to the structural member to join the structural members together, and further, an adhesive is filled between an outer peripheral surface of the structural member and a peripheral wall of the structural member insertion portion. Since the members are tightly connected, the structural members can be rigidly joined to each other to improve the joining strength. In addition, since they are tightly bonded with an adhesive, the expansion and contraction of structural members such as wood can be absorbed and rattling can be prevented. it can. h. Since the joints between structural members such as columns, beams, and girders have a rigid frame structure that is firmly joined with a joining tool and an adhesive, the frontage (span) of the building without using load-bearing walls or braces
Can be significantly expanded, and a space without pillars can be obtained.

[0022] Here, as the length of the joint instrument insertion portion, preferably formed in the body portion and having substantially the same length of at least connectors. When the discharge port of the adhesive is formed on the tip end side of the body, it is formed at least at a depth where the discharge port is not buried. As the length becomes shorter (shallower) than the length of the body of the connector, the length of driving or screwing the tip to the bottom of the connector insertion part tends to be longer, and the workability tends to decrease, and the adhesive is filled. There is a tendency that the volume between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion becomes smaller and the binding force by the adhesive decreases, and the bottom of the connector insertion portion is pushed open by the body by the connector. There is a tendency for cracks and the like to occur on the surfaces (outer peripheral wall surfaces) of columns, beams, girders and the like . Further, as the length becomes longer (deeper) than the length of the body portion of the connector, the length of the tip portion of the connector that can be driven or screwed to the bottom of the connector insertion portion becomes shorter, and the fixing force by the connector decreases. There is a tendency,
Neither is preferred. Also, the connector insertion part is a pillar,
Depending on the size of the structural member such as a beam or a girder , it is formed inside the outer peripheral wall of the structural member at a position 1.1 to 6 times the outer diameter of the body or neck of the joint. When a large external force is applied to the structural member from the outer peripheral wall surface of the structural member such as a column, a beam, or a girder to a position smaller than 1.1 times the outer diameter of the body or neck of the joint, the end of the structural member is There is a tendency to break, and as it becomes larger than six times, the number of connector insertion portions that can be formed in the structural member decreases, and it tends to be difficult to improve the bonding strength between the structural members, and both are not preferable.

[ 0023 ] The size of the connector insertion portion is 3 mm to 15 mm, preferably 5 mm to 5 mm from the outer diameter of the body of the connector.
It is formed 12 mm larger. As the difference between the outer diameter of the connector insertion portion and the outer diameter of the body of the connector becomes smaller than 5 mm, the adhesive discharged from the discharge port is bonded depending on the type of the adhesive and the construction time (summer and winter). There is a tendency that it is difficult to flow between the outer peripheral surface of the body of the fitting and the peripheral wall of the fitting insertion part, and as the difference from the outer diameter of the body of the fitting becomes larger than 12 mm, there is a tendency to require more adhesive than necessary. And both are not preferred.
If the connector has a neck, it is preferable that the size of the connector insertion portion be substantially the same as the neck. As it becomes smaller than the neck of the connector, it becomes more difficult to insert the neck of the connector into the connector insertion portion, and as the diameter becomes 1.5 times or more the neck of the connector, the torso portion of the connector and the peripheral wall of the connector insertion portion. There is a tendency that the adhesive filled in between leaks from the head side of the connector, which is not preferable. When the inner diameter of the connector insertion portion is larger than the outer diameter of the neck portion, leakage of the adhesive can be prevented by using a washer. Furthermore, the connector insertion portion is formed in an arbitrary cross-sectional shape such as a circle, an ellipse, a polygon such as a square or a hexagon.

[ 0024 ] Further, as the connector insertion portion, a column, a beam, a girder may be used.
When a large external force is applied to the tip of a structural member such as a horizontal cantilever, it is preferable to form the member with an inclination angle α.
° ≦ α <90 °, preferably 20 ° ≦ α ≦ 70 °, more preferably 30 ° ≦ α ≦ 60 °. As the angle of inclination becomes smaller than 30 °, the position of the connector insertion part
There is a tendency that the structural members such as columns, beams, girders, etc. approach the ends of the structural members and are easily damaged by a large external force. As the inclination angle becomes larger than 60 °, the length of the joint becomes too long. Therefore, the workability tends to be reduced, and both are not preferable. In particular, when the connector insertion portion is formed from the upper outer peripheral wall side of a structural member such as a column, a beam, a spar, or the like , the connector is inserted from above the structural member and is easily driven into the bottom of the connector insertion portion or The workability can be improved by screwing, the head of the joint can be prevented from being exposed on the lower outer peripheral wall of the structural member, and the appearance can be improved. In addition, the outer peripheral surface of the joint can be inserted into the joint. This has the effect that the adhesive can be reliably filled between the peripheral walls of the portion. In addition, at the contact surfaces of the structural members such as columns, beams, and girders to be joined, the other joint insertion portions are perforated so as to be cross-shaped with the joint insertion portion at predetermined intervals, and each joint insertion portion is formed. When joining the structural members by inserting the joints, the loads from the top, bottom, left and right, such as tension, bending, and shear, of the joined structural members can be canceled by the couple of each joint, and the joining force between the structural members can be reduced. Can be improved. Further, by forming the connector insertion portion with an inclination angle α or forming a cross shape, even in the case of a two-way rigid frame structure or a case where there are structural members in three or four directions, a column using the connector is used. It has an effect that structural members such as beams, beams, and the like can be joined to each other. As the adhesive, an epoxy resin adhesive, a polyurethane adhesive, a vinyl acetate resin adhesive, or the like is used.

The columns, beams, bonding apparatus digit etc. according to claim 6 of the present invention is the invention according to claim 5, pillar that contacts the beam, one of between said structural member digit etc. One or a plurality of air vents perforated from the outer peripheral wall of the structural member to the connector insertion part are provided.

[0026] Thus, in addition to the operation of claim 5, having the following effects. i. Types of columns, beams, girders, etc. (things that have air permeability such as concrete and materials that do not have air permeability such as laminated wood)
Depending on the case, when injecting the adhesive into the hollow part of the joint,
The air in the hollow portion and the connector insertion portion is discharged from the air vent portion, and the adhesive can be smoothly filled between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion. j. By confirming that the adhesive overflows from the air vent portion when the adhesive is injected, it can be confirmed that the adhesive has been filled between the outer peripheral surface of the joint and the peripheral wall of the joint insertion portion.

[0027] Here, the air vent is preferably formed at a position apart from the discharge port of the connectors, the discharge port cylinder of connectors if it is formed on the front end portion of the body portion of connectors In the case where the discharge port is formed on the head side of the body of the connector, the discharge port is formed on the tip side of the body of the connector. Thereby, it is possible to prevent the adhesive from overflowing from the air vent portion before the adhesive is filled between the outer peripheral surface of the joint and the peripheral wall of the joint insertion portion, and it is possible to reliably prevent the outer peripheral surface of the joint and the joint insertion portion from being filled. The adhesive can be filled between the peripheral walls. In addition, the air vent portion has an arbitrary shape such as a substantially circular shape, a substantially elliptical shape, and a polygonal shape such as a square, and is pierced in a size that allows the adhesive to be injected smoothly. Further, after the adhesive overflows from the air vent portion, if the diameter of the air vent portion is large, a plug such as a wooden plug may be driven in to make the flush with the outer peripheral wall surface of the structural member. This allows pillars,
The appearance of beams, girders, etc. can be improved.

The bonding apparatus columns, beams, digits, etc. according to claim 7 of the present invention is the invention according to claim 5 or 6, it is formed in the opening of the joint instrument insertion portion the connectors inserted A buried material having at least one seat portion orthogonal to the portion, burying an opening side of the seat portion, and having a surface formed substantially flush with an outer peripheral wall surface of the structural member such as a column, a beam, or a girder . It has a configuration.

[0029] Thus, in addition to the operation of claim 5 or 6, it has the effect of following. k. It is possible to prevent the head of the connector from protruding greatly from the surface of the pillar, beam, spar , or the like , or to prevent the surface of the column, beam, spar , or the like from being depressed, thereby improving the appearance. l. By burying the buried material on the opening side of the seat, the head of the connector can be prevented from being exposed , and columns, beams,
The bonding tool can be protected from the high temperature of fire by the carbonized film of the girder or the like, and the safety can be improved. m. Pillars potting material, beams, since the outer peripheral wall surface substantially flush with the digit or the like can be improved columns, beams, the appearance of the digits, and the like. n. Since the embedding material is embedded on the head side of the joint, external heat can be prevented from being transmitted to the joint, and external heat can be prevented from being transmitted to the inside through the joint.

[0030] Here, as the potting material, with one having a freely protruding portion inserted into the inlet of the connectors, the opening side of the seat with the opening is sealed by inserting the protruding portion into the inlet May be buried.

The pillar of claim 8 of the present invention, the beams, the welding device digit or the like, the invention according to any one of claims 5 to 7, the pillar that contacts, beams, digits, etc. a fixed portion which is parallel or perpendicular fixed to the fixed or the contact surface the contact surface of either one of the structural members of between said structural members, standing設又the fixing portion is extended 1 Or a plurality of upright wall portions and an engagement portion formed with the upright wall portion and engaged with the other structural member that is in contact with the upright wall portion.

[0032] Thus, in addition to the operation of the claims 5 to 7, it has the following effects. o. By fixing the fixing portion of the joint fitting to the contact surface of one of the structural members such as the pillar, the beam, and the girder , and by engaging the other structural member with the engaging portion formed on the upright wall portion, the structural members are joined together. Can be joined, and when joining the structural members by the joining tool, the structural members can be joined accurately, and the joining accuracy can be improved. p. Since the structural members such as columns, beams, and girders can be temporarily fixed with the joint metal and the contact surfaces of the structural members can be substantially adhered to each other, the adhesive is injected into the joint inserted and fixed in the joint insertion portion. In this case, it is possible to prevent the adhesive from leaking from the contact surface. q. Each structural member such as a column, a beam, and a girder can be tightly fixed by the joint and the joint, and the concentration of the concentration on the joint can be dispersed by the joint so that the joint can be reduced in size. In addition, it is possible to prevent rattling of the joint due to expansion and contraction of the structural member with the joint, and it is possible to improve joint strength such as shearing and tension at the joint. r. By using the joint and the joint together, the joint can be used as a reinforcing material, and the joint can be reduced in size. s. Since structural members such as columns, beams, and girders can be tightly fixed to each other with a joint fitting, a joint, or an adhesive, a wide frontage without pillars can be formed without using load-bearing walls or braces.

[0033] As the fixing unit, columns, beams, it is fixed by screwing or the like by a bolt or the like to the contact surface of the digits, and the like. The engagement portion is formed in a hook shape, a plug-in protrusion shape, or the like.
