[Background Art] The Great Hanshin-Awaji Earthquake left the victims with extremely devastating aftereffects that could not be physically or mentally restored, but also raised various problems in the field of science and technology and solved them. This resulted in leaving a big issue of preparing for the future. Contrary to the rapid progress of science and technology, many wooden houses collapsed due to this earthquake, crushing the people who lived in it and making it impossible to escape, creating many victims From the painful fact that it came to the point, it emerged as a problem that had not been predicted until now whether each structure related to the traditional wooden frame structure was sufficient in terms of building technology or building regulations. However, the fact that it is urgently needed to be reviewed is one of the major issues in such science and technology fields.

The recent revision of the Building Standards Law is to greatly relax the structural regulations on the wooden frame structure up to then, such as the normal construction of a three-story wooden frame structure. For the traditional Japanese wooden frame structure, it was beginning to be accepted with great expectations as an epoch-making change that creates various possibilities in the future, but this wooden shaft that was raised as a trigger for the earthquake disaster The need for re-inspection and re-examination of the structure of each group is important for the building industry, especially for those who are engaged in wooden construction and the government agencies that guide and supervise it.
It is expected to be a heavy burden in the future. The applicant of the present application need not take such a sudden situation as an opportunity,
Already represented by the invention of Japanese Patent Application No. 3-86265, a horizontal member and an auxiliary horizontal member which is arranged side by side with a working space at an appropriate interval above the horizontal member are integrated, and the joint portion is connected. Completed a completely new wooden framework structure in which it is connected vertically with a dual-purpose reinforcing member to firmly connect to the side of a unified wooden pole, and standardization of members that could not be handled by conventional wooden framework structures We have succeeded in developing a technology that can simplify the cutting process and even the structural strength of the joint.

This invention is one of the problems as a result of examining the correspondence with some problems posed by the earthquake disaster based on the technical idea already developed by the applicant of the present invention. This is the start of technological development that is effective in preventing the floating phenomenon of the column member (adding and strengthening the tensile strength of the column). In other words, it has been known that pillars that are divided by horizontal members will always cause a floating phenomenon when horizontal force is applied. The structure has been obligatory. However, since the three-storied wooden structure was made possible by the revision of the law, it became possible to adopt a technique of connecting the upper and lower pillars by using a metal fitting instead of the through pillar, and applying the technology. As mentioned above, people have stepped into the practical application of a wooden frame structure with pillars that were unified by their own structure as described above, and have accumulated a track record, but Kretek (brand name) metal fittings that have appeared at exactly the same time. That is, the connection fittings that receive the horizontal material like a chin on the side of the pillar,
It was also influenced by the fact that the already-developed joint of the applicant of the present application was judged to have a sufficient possibility of being adopted in terms of good workability, reliability in strength, etc. We have repeated further trials and experiments considering the use of metal fittings.

As a result, in the joint structure already developed by the applicant of the present application, including the case of realizing the joint structure adopting the CRETECH (trade name) metal fitting, the pillar with the metal fitting like a hire is interposed. It was found that the technology related to the tensile strength of the joints of the upper and lower columns is particularly important for preventing the collapse of the house that was posed by the previous earthquake when realizing a wooden frame structure that passes through the top and bottom. That is, unlike a so-called single through column, a joint post that receives an unexpected external force such as a momentary strong vertical movement or rolling impact, such as during an earthquake, is the joint part. Is damaged by the slight clearance between the bolts used to secure the joint metal fittings and the wooden poles that make up the structure, and the bolt insertion holes therefor, and the external force applied is concentrated at the locations with the clearances. It causes a shear fracture, and a force more than the calculated value is applied to the bolt, which easily causes a bending deformation fracture. It is a technical matter that has not been taken up until the necessity of taking action.

As a technical means for eliminating this clearance, the simplest method is to use a wedge-shaped metal fitting instead of the bolt, but a structure in which the wooden pole and the joint metal fitting are integrated by the wedge-shaped metal fitting is used. When adopted, in addition to the problem that it is difficult to adjust the degree of biting into the hole corresponding to the bolt hole and it is difficult to adjust, the risk that the wedge-shaped metal fitting gradually begins to loosen due to the usual slight swings peculiar to wooden structures cannot be ignored. In that respect, there is a risk of lack of reliability in durability, and therefore, in the present invention, the development and research of a new joint structure that does not cause those problems is continued, and as a result of many trial and error, finally, We have come to realize the extremely effective and highly reliable integrated structure of the wooden pole joint fitting and the wooden pole joint structure using it, and the details are given below. While the specific embodiment shown in the plane as a reference, it is an Let sequentially Setsuji.

DETAILED DESCRIPTION OF THE INVENTION As will be clearly understood from the representative embodiments shown in the drawings, the wooden frame structure of the present invention is
Basically, it has the following configuration. That is, a female screw portion is formed at the lower end that matches the axis of the metal fitting body, the upper end side is orthogonal to the axis of the metal fitting body, and is vertically spaced from each other, and the plane arrangement angle is phased. The wooden pole embedding joint metal fitting with a pair of through holes is inserted from the wooden pole post base into the embedded hole formed to match the coaxial center. Insert the fixing bolts respectively from the through holes that are pre-formed around the pillars of the wooden pillars so as to correspond to the respective holes of the wooden fittings, and tighten the nuts to attach the wooden pillars to the wooden pillars. After being fixed to the column base, the female screw part formed on the lower end of the wooden post embedding joint metal fitting is used to apply a pulling force to the outer side of the wooden pillar post Fixing where the metal fittings intervene between the wooden poles and between them An integral structure of the tree pillars embedded for seam hand bracket which is to achieve an embedded structure with no play for the belt.

The joint fitting for embedding a wooden pole is, in terms of its workability, durability, economy, and on-site handleability,
It is preferable to process a steel rod rather than a pipe material.The steel rod is formed in the female screw part by matching the material axis from the lower end and forming a screw hole of a predetermined diameter, and the upper part that does not affect the female screw part , In the direction orthogonal to the material axis, with an appropriate space above and below considering shear strength, etc., without overlapping each other in the plane arrangement, and with an angle according to the cross section of the wooden pole, for example, a square cross section It is formed as a structure having at least a pair of through holes for inserting bolts, which are arranged to be phased with each other at an angle of 90 ° if they exist and a hexagonal cross section has an angle of 120 °.

A wooden pole is a member cross section that is generally calculated according to various factors such as the size and type of a building such as a two-story building, a three-story building, and is not limited to natural wood, and is not limited to laminated wood. There is no problem even if it is made of a laminated material, and it has a diameter that does not hinder the insertion of the above-mentioned wood pillar embedding metal fittings according to the shaft center from the wood mouth. A hollow hole with a depth deeper than the entire length is formed, and from the side surface near the column base, it is formed in phase with the wooden pole embedding joint metal fitting when the wooden pole embedding metal fitting is stored. Through holes for inserting bolts are formed so as to match the through holes. Therefore, these through holes are formed in a state of penetrating the above-mentioned hollow.

In the hollow of the wooden pole thus prepared,
The tip of the joint bracket for embedding the wooden pole is maintained with its lower end kept deeper than the mouth of the wooden pole, and a bolt is inserted from the through hole formed on the side of the wooden pole's pedestal. The wood pillar embedding bracket is pierced through while adjusting the rotation of the wood pillar embedding fitting appropriately so that the threaded portion fits into the through hole entrance of the wood pillar embedding metal fitting, and the wood pillar pillar leg on the opposite side is pierced. If it corresponds to a place where a washer is inserted into the same threaded portion that is protruding from the side surface, or where other metal fittings, for example, a horizontal material receiving metal fitting such as a Clerac hardware (trade name), are attached, By fixing the nut with the metal fitting, the joint fitting for embedding the wooden pole is fixed in the wooden column base.

The joint fitting for embedding the wooden pole in this state is
The structure in which the lower end thereof is fixed to the back of the wooden pole by about 3 to 5 cm, for example, realizes a structure that is temporarily fixed. The bolts arranged orthogonally to the axis are the bolts. Has a structure that has a play corresponding to the clearance between the through hole and the through hole, which is formed with a minimum margin required for inserting the wooden pole. The bolt itself that connects the wooden pole to the foot of the wooden pole also has a clearance between it and the through hole of the wooden pole, which is formed with a minimum margin necessary for inserting the bolt. As a result of this structure, in the end, the wooden pole embedding bracket is fixed to the wooden pole base with a structure that has play for both clearances. Become.

Therefore, in order to realize a joint of a wooden frame structure, that is, an integrated structure in the vertical direction, by using this wooden pillar, the lower end of the wooden mouth should be used for a structural portion to be connected, for example, a pillar on the first floor. For example, if it is a basic structural surface, and if it is to be used for a second-floor pillar, it will be a cross-member surface such as a girder or beam, or when it must form a through-column The male screw portion of the male joint fitting which is projected from the structure portion is screwed into the female screw portion of the wooden joint embedding joint fitting which is fixedly embedded in the wooden pillar leg portion, and is carried out later. By applying a pulling force, that is, an external force acting on the entrance side of the wooden pole to the wooden pole embedding joint metal fitting by some structural means typified by an example, , Wood between and through the above mentioned bolts Formed by eliminating the play by both of the clearance between, it realizes the integrated structure of the tree pillars embedded for seam hand bracket of the present invention. Hereinafter, some typical examples of the wood pole joint structure realized by using the integrated structure of the wood pole embedding joint metal fitting of the present invention shown in the drawings will be described. The integrated structure of the joint fitting for embedding a wooden pole included in the invention is made easier to understand.

[Embodiment 1] A perspective view of a main part including a partly omitted part shown in an exploded state of FIG. 1, a main part of FIG. 3 is greatly omitted, and a main part shown in a state where a horizontal member J1 is connected. As can be understood from the longitudinal cross-sectional view of the part, the wooden pole joint structure using the integrated structure of the wooden pole embedding joint metal fitting of the present invention realized by this embodiment has a wooden pole as a first floor pillar. It is a typical example of the structure used. That is, a female screw portion 12 that matches the axis of the metal fitting body 11 is formed at the lower end, is orthogonal to the metal fitting body axis at the upper end side, and is vertically spaced from each other and has a plane arrangement angle of 90 degrees. ° The wood pole embedding joint metal fitting 1 in which a pair of through holes 13 and 13 having a phased relationship is formed from the pole base of the wood pole 2 to the embedding hole 21 formed in conformity with the coaxial center L. When the wooden pole embedding joint fitting 1 is inserted, the wooden pole 2 is inserted at least 10
The recessed space 5 is secured by a recessed arrangement of about mm, and it corresponds to the through holes 13, 13 of the wooden pole embedding joint fitting 1 inserted in the recessed shape (that is, the through hole 22). So that the shaft center h1 of each of them coincides with the shaft center H1 of the through hole 13, the fixing bolts 3 fitted with the washers 32 are respectively inserted through the through holes 22, 22 formed in the vicinity of the pillar base of the wooden pole 2. The tip of the fixing bolt 3 which is projected from the side surface on the opposite side of the wooden pole 2 by penetrating through each of the through holes 13 or 13 of the wooden pole embedding metal fitting 1 buried in the above-mentioned state After fitting the horizontal material receiving bracket J1 on the side, tighten the nut 31.
(1) Fix the joint metal fitting 1 for embedding the wooden pole to the column base of the wooden pole 2 together.

After that, a state in which a washer 44 having a diameter larger than the diameter of the post base wood mouth embedding hole of the wooden pole 2 is fitted into the connection bolt 4 in which the nut 43 has already been screwed halfway, and is supported by the nut 43 above. In addition, the male screw portion 41 is screwed to the female screw portion 21 formed at the lower end of the wooden pole embedding metal fitting 1 to a predetermined depth, and then the previously screwed nut 43 is returned, that is, When the washer 44 is moved toward the tip of the connection bolt 4 and pressed against the post base of the wooden pole 2, the metal fitting main body 1 has the descending space portion 5.
1, the reaction force from the washer 44 using the wooden pole post base as the support portion acts on the pulling force to the outside of the wooden pole base wood mouth, so that the wooden pole embedded joint fitting 1 is A surely integrated embedded structure with no play is realized with respect to the fixing bolt 3 and the wooden pole 2.

As a result, the connection bolt 4 screwed to the lower end of the wooden pole embedding joint metal fitting 1 having a play-free embedded structure also has a play-free integrated structure with respect to the wooden pole 2, and thus the wooden pole. The head 42 of the connecting bolt 4 is embedded in the foundation structure portion B in a state where the wooden pillar 2 in which the joint fitting for embedding is integrated without play is maintained vertically on the foundation,
Head plate A of integrated anchor bolt A
1 is connected to the base structure 1 by a welding means, and then the space B1 of the base structure B is appropriately filled with mortar and the like, and the wood posts 2 are integrated on the base structure B. The wooden pole joint structure of the first floor portion using the integrated structure of the wooden pole embedding joint metal fitting 1 which is the basic configuration of the present invention is completed.

As shown in FIG. 1, in this wooden pole joint structure, in order to realize a strong integrated structure with the foundation structure B, with respect to the axis L of the wooden pole 2. Then, the axis of the embedding hole 21, the axis of the female screw portion 12 of the wooden pole embedding joint fitting 1, the axis of the connecting bolt 4, and the axis of the anchor bolt A are all directly on top of each other. It is an extremely important factor to be formed in a precise manner, and requires careful attention. On the other hand, in this example,
Fixing bolt 3 of joint bracket 1 for embedding a wooden pole is connected to a base (not shown) in a mouth opening in a chin-like shape, and a horizontal bridge receiving bracket (Kretec metal product under the product name) J1 is arranged. Although an example of a structure that also serves as a metal fitting for integration with the wooden pole 2 is given, this is not necessarily an essential constituent element in the present invention, and the joint structure with the base is not limited to that, and the well-known joint structure, etc. It is of course possible to substitute with.

[0017]

[Embodiment 2] A perspective view of a main part including a partially omitted part shown in an exploded state in FIG. 2 and a state in which a middle part of a column in FIG. 3 is largely omitted and a horizontal crossing bracket J2 is connected. As can be understood from the longitudinal sectional view of the main part, the wooden pole joint structure using the integrated structure of the wooden pole embedding joint metal fitting of the present invention realized by this embodiment has a wooden pole of a second floor or higher. This is a typical example of a structure that is used as a pillar of the building and is directly connected to the pillar on the floor below it to realize a through pillar structure. First, the structure of the column base portion of the wooden pole 7 used for the pillars of the second floor and above (the second floor is assumed in this embodiment) is integrated with the foundation structure B in the first floor portion of the above-described first embodiment. In the structure for replacing, instead of the connecting bolt 4, a male joint metal fitting 6 is adopted, and instead of the structure in which the connecting bolt 4 is connected to and integrated with the foundation structure B through the anchor bolt A. It is assumed that the male joint fitting 6 is fixed to the pillar head of the wooden pole 2 below it (the first floor in this embodiment) to be connected,
The male threaded portion 62 is screwed into the female threaded portion 12 of the wooden pole embedding joint fitting 1, and in the previous embodiment, the washer 44 is pressed against the wood mouth to obtain a reaction force, and the wooden pole embedding joint is obtained. In contrast to the pulling force acting on the metal fitting body 11 of the metal fitting 1, in this embodiment, the stigma of the first floor wooden pole 2 to which the male joint metal fitting 6 is fixed is the pillar of the wooden pole 7. By being pressed against the leg opening, the metal fitting body 11 of the wood pillar embedding joint fitting 1 and the metal fitting body 61 of the male joint fitting 6 of the wood pillar 2 are pulled toward the outside of each wood mouth. It is the one in which force acts.

Therefore, the wooden pole 7 corresponds to the wooden pole 2 in the first embodiment, the embedding hole 71 is the same as the embedding hole 21 in the first embodiment, and the through hole 72 is the same in the first embodiment. The other configurations, that is, the wooden pole embedding joint fitting 1, the fixing bolt 3, and the descending space portion 5 have substantially the same configuration, and therefore are represented by the same reference numerals for convenience. There is.

In contrast to the second-level wooden pole 7 formed as described above, the head portion of the wooden pole 2 on the first floor to be connected is screwed to the female screw portion 12 of the wooden pole embedding joint fitting 1. The male joint fitting 6 having the matable male screw portion 62 is fixed. That is, a male screw portion 62 that can be screwed into the female screw portion 12 of the wooden pole embedding joint fitting 1 is formed at the upper end, and
A through hole 63 is formed on the lower end side of the fitting body 61 at right angles to the axis of the fitting body 61.
It is inserted from the stigma of the floor wooden pole 2 into the embedding hole 23 formed so as to match the coaxial center L, and corresponds to the through hole 63 of the male joint fitting 6 for embedding which is in this insertion shape (that is,
The fixing bolt 8 fitted with the washer 82 is inserted from the through hole 24 formed in advance around the stigma of the wooden pole 2 so that the axis h2 of the through hole 24 matches the axis H2 of the through hole 63.
The male member for embedding fitting 6 is fitted with a horizontal member receiving member J2 at the tip portion which penetrates the through hole 63 of the embedding member for embedding 6 and projects to the opposite side, and then the nut 81 is tightened. 6 is fixed to the wooden pole 2 stigma of the first floor to be connected.

In this embodiment, the horizontal member receiving bracket J
Since it is necessary to more firmly fix the two wooden poles to the two stigmas, the reinforcing bolts 9 parallel to the fixing bolts 8 are used together, and the reinforcing bolts 9 are embedded in the wooden poles two stigmas. In this example, the wooden pole 2 is penetrated at a position where it does not hang on the embedded male joint fitting 6. Then, as is clear from the horizontal cross-sectional view of FIG. 4, the fixing bolt 8 has a structure that also serves as a metal fitting for integrating the horizontal material receiving metal fitting J2 with the wooden pole 2 as in the first embodiment. The joint structure for connecting and integrating a horizontal member (not shown) such as a beam or a girder to the wooden column 2 is not necessarily limited to the structure using the horizontal member receiving metal fitting J2, and is publicly known as appropriate. Needless to say, it is possible to adopt the joint structure of.

Thereafter, the male screw portion 62 of the fixed male joint fitting 6 for embedding is attached to the female screw portion 12 of the joint fitting 1 for embedding wooden poles fixed to the column base of the wooden pole 7 as shown in FIG. As shown in the partial perspective view, when the wooden pole 7 itself is rotated around the coaxial center L and screwed, the metal fitting body 61 of the male joint fitting 6 for embedding moves inside the descending space portion 5 of the wooden pillar 7. Proceeding to the state where the pedestal opening of the wooden pole 7 and the stigmatic opening of the wooden pole 2 of the first floor to be joined are brought into contact with each other. By further strengthening this process, the wooden pole embedding joint fitting 1 and Applying a pulling force to both of the male joint fittings 6 for embedding, the joint fitting 1 for embedding wooden poles and the male joint fitting 6 for embedding
Both of them are integrated into the wooden poles 7 or 2 in which they are embedded without play, and the upper and lower wooden poles 7 and 2 have a wooden pole joint structure with structural strength comparable to that of a single through-column. To realize.

[0022]

[Effects] The integrated structure of the wood pole embedding metal fitting of the present invention having the above-mentioned structure is made clear in a typical embodiment of the wood pillar metal joint structure using the metal fitting. , It is possible to embed and fix the wood pole embedding bracket to the center of the wood pole without any rattling for a long period of time. In addition, momentarily strong vertical movement and rolling impact, etc.
Even if it receives an external force that can not normally be assumed, it is possible to realize a structure that does not rattle while having a clearance between the fixing bolt and the bolt insertion hole therefor. As described above, the external force applied causes rattling due to the clearance, and the risk of concentrating the external force at that location and shearing and destroying the wooden pole is not only to be assumed, but not only the bolt. It is also possible to eliminate the possibility that bending deformation and fracture can be easily caused by applying a force over the calculated value to, and there is almost no difference from the case of a so-called single through column, which is extremely safe and highly reliable. Alternatively, it is possible to realize a joint structure between the wooden pole and the foundation structure part.

Therefore, it is possible to surely prevent the risk of a two-story wooden house with a one-story building that has been exposed due to the Great Hanshin-Awaji Earthquake from falling out of the foundation structure and collapsing due to shear failure. In addition, it is expected that it will greatly contribute to the safety of the building by the three-story wooden frame structure that was made possible by the revision of the law. It has already been developed by the applicant of the present application, including the case where a joint structure is realized by using a horizontal material receiving metal fitting such as KRETEC (trade name) metal fitting, which has recently started to attract attention because it is possible to realize a group structure. Since it is extremely easy to realize the finished joint structure, it becomes easy to standardize the constituent members of the wooden frame structure and promote the factory production. DOO surface such spread Wooden structures of Japanese traditional Advantageously structure in some cases than or evenly matched in prefabricated building which has taken closed at, is to allow the gradually allowed to settle.

Particularly, according to the wooden pole joint structure using the integrated structure of the wooden pole embedding joint metal fittings, which is the basis of the present invention shown in the embodiment, the wooden pole embedding joint metal fitting 1 is provided with the wooden pole 2 Alternatively, as a means for embedding and fixing in the shaft center portion of 7, the most rational and simple structure which has been conventionally adopted as the mother body from the viewpoint of workability, workability, economy, etc. Wooden poles 2 or 7 and wooden pole embedded fittings 1
In addition, a structure is adopted in which the fixing bolts 3 are pierced through in a skewered shape, and the diameter of the through hole or the through hole required for piercing the fixing bolts 3 is the same as that of the conventional one, which does not have a practical problem. It is possible to surely eliminate rattling with respect to the fixing bolt 3 while keeping it as it is, and to integrate all the wooden poles 2 or 7 on it from the base structure portion B extremely firmly and easily, and to place it safely and reliably It is expected to be very useful for realizing the wooden frame structure.

As described above, the integrated structure of the joint bracket for embedding a wooden pole of the present invention and the wooden pole joint structure using the same achieves the intended purpose with an extremely simple structure and is economical. It is possible to complete a wooden frame structure that is excellent in workability and extremely excellent in earthquake resistance, and the wooden frame structure from Japan's ancient times, which has been declining so far,
It can be said that it will be highly evaluated in that it will be possible to provide it as a wooden frame structure construction that meets the standards that are required by the modern society, again with the content that general users expect.
