2. Description of the Related Art In the wooden housing industry in Japan, a Japanese-style building style based on a traditional frame structure is mainly used for a building contractor mainly engaged in on-site construction, or a Western style building style based on a large wall structure. Regardless of the prefab builder who pursues the factory production system, we have been aiming for quality improvement for many years from a comprehensive point of view such as high quality housing, low price, shortened construction period. In addition to the need to differentiate itself from other companies in the industry, the competition for development and research continues to intensify, and as a result, the quality of wooden houses has recently been raised to a fairly high level. Have been successful.

[0003] However, a further analysis of the entire wooden housing industry suggests that the growth of wooden housing by the prefabricated construction method is remarkable because of the high quality control, the design ability, and the advantages of the construction period. The situation is generally extremely difficult for contractors who continue to supply wooden houses with traditional framed construction methods, but due to the strength of Japan's traditions, especially in rural areas, the appearance has continued. The popularity of wooden houses with traditional framed construction methods using beautiful natural wood has continued for some time, and traditional local contractors have been evolving prefab architectures, barely supported by these trends. It is driving the sense of opposition to traders.

[0004] Due to the extremely serious internal situation such as the lack of craftsmen related to special skills such as plasterers and carpenters, such a traditional contractor, from a very early stage, a member forming a skeleton of a wooden frame structure, For horizontal members such as bases, beams, girders, and fire struts, columns, bundles, etc., almost all processing points including joints and joints are cut with machine tools in the workplace, and building members are cut as much as possible. Efforts are being made to minimize the need for complicated manual work at construction sites by converting to factory production, and as a result, the processing dimensional accuracy of members has been reduced compared to conventional ones that mainly focused on on-site processing. On the contrary, it has improved remarkably, and the quality control has been improved so as to be comparable to that of the prefabricated construction method.

In spite of such efforts, in the construction by the traditional framing method, natural wood is used as a main framing member, even if drying treatment, chemical treatment such as antiseptic and insect repellent is performed in advance. As a fate, it is extremely difficult to stop the unevenness and distortion of wood quality, and even frame members that have been machined with high precision in the corner workplace often cause dimensional changes in the machined part at the stage of construction. ,for that reason,
It still has the real problem that it is difficult to make the joint structure and joint structure of the members as designed in terms of strength, and let's implement it to save labor The cutting process itself using a machine tool is also reducing the number of craftsmen who take over traditional techniques, and the complicated joints and joints are not understood, and even the odd machining is becoming impossible to use. Due to problems, it is feared that the background foundation for the implementation and continuation of the timber frame method will continue to fluctuate in the future.

Therefore, in the case of a joint structure, for example, a joint fitting formed into a special structure is attached to one of the vertical and horizontal members to be joined, and the other is connected to the joint fitting at a minimum. (For example, linear grooving and drilling), it is possible to realize those structures with precision and stability, so to speak, the joint structure and joint structure similar to steel structure A variety of joints for a frame structure, which is a hand structure, and connections and joint structures using the same have been developed and provided so far.

[0007] As a typical example of such a case, in the invention disclosed in Japanese Utility Model Publication No. 1-2003, a column and a pair of horizontal members which must be horizontally butted and joined around the column capital are described. A connection structure using a new connection metal fitting has been proposed as a connection structure. Each of the ends of the two horizontal members that are horizontally abutted, and the column member located immediately below the abutted ends,
A fitting groove that is continuous with each other and that opens in the form of one narrow groove is formed, and a total of three horizontal bolts pass through each of these fitting grooves. By driving the fitting from above, all horizontal bolts are configured to be fitted into one fitting, and each bolt of the fitting is fitted. In part,
An inclined portion that expands toward the tip (lower end) side is formed in advance, and even if there is a slight gap between the pillar and the horizontal member, the bolt is forcibly forced in the process of driving the connection fitting. And the members in the joined state are attracted to each other, and finally settle in an accurate positional relationship as designed.

However, in the joint structure using the above-mentioned joint fitting, the members to be joined remain independent and separated in a completely unrelated state at the erecting stage before driving the joint fitting. In this case, the worker stops around the mounting position of the connection fitting of the pillar, which has an unstable structure and stands upright, and pulls the end to be joined of the horizontal member suspended by a crane, etc. The end of the horizontal member is joined to the column by the coordination work of the force of the crane and the operation of the crane, and the bolt insertion work must be quickly performed while the bolt hole does not shift, and it must be completed. Even though the relationship between the two remains extremely unstable and the connection structure is finally realized as prescribed, there remains a problem in terms of workability such as safety and work efficiency, Of low practical value. There was no.

In view of the above situation, the inventor of the present application has
Without depending on the power of the worker at the construction stage, the hanging work by the crane etc. can be released in an early stage, and finally the members are pulled together at the connection point and tied together. Focusing on the method of forming the connection and the necessity of building hardware used for it, development and research started quickly,
As a result of repeating trial and error and numerous trial experiments over a long period of time, this time, we finally completed the connection method of the wooden frame consisting of a new configuration and the connection fitting for the wooden frame structure used for it, It was successfully put to practical use. In the following, the configuration of the present invention will be described in detail with some embodiments representative of the present invention shown in the drawings.

[0012]

[Related Invention 1] The above-described method for forming a joint of the present invention is realized by using a joint for a wooden frame structure having the following structure. The gist of the configuration is that one or a plurality of flange portions are integrally formed on the web portion to form a substantially “T” shape, “L” shape, rollover “U” shape or “E” shape in plan view. A plurality of bolt insertion holes at predetermined intervals in the vertical direction are drilled in at least two rows in the flange portion of the metal fitting main body (in the case of a plurality of pieces, common to all the flange portions). In one row of bolt insertion holes, a bolt insertion hole including a wedge hole narrowing in a direction away from the web portion and a cutout receiving hole having an open upper portion is formed. An interrupting fitting formed with a spaced bolt insertion hole, a positioning pin having a tapered tip side, inserted into a bolt inserting hole including a wedge hole of the interrupting fitting, used, and a transverse frame to be connected. While being inserted transversely near the lumber mouth, Notch receiving hole to fit a wooden framework structure for Joint fitting comprising a combination of a temporary support shape is the hanging piercing bracket.

Before describing in detail the method for forming a joint of a wooden frame according to the present invention, first, the structure of a wooden frame structure structural joint used therein will be described. And alignment pins and hanging piercing
It is basically formed from steel, but if it has the required properties such as mechanical strength and heat resistance equivalent to steel, it shall be made of other materials such as industrial plastics It is also possible.

The interruption metal fitting is a member which forms the center of the connection metal fitting and is connected to and fixed to the side of the column material at the connection structure forming portion, and is formed in a protruding shape in the connecting direction of the horizontal material. It is inserted into the connecting vertical groove formed on the lumber opening side, and the interrupting bracket and the horizontal member are both inserted transversely through the tightening bolts and nuts to integrate the interrupting bracket and the horizontal member, so that the final To achieve a connected structure, a horizontal member is abutted on the predetermined side of the column material, and a conventional connection structure is used. Replaced with a structure that supports a part of the kiguchi on the chin.)
It fulfills its function.

Therefore, this interrupting metal fitting has a web portion abutting on a predetermined portion of the side surface of the pillar material of the metal fitting body, and a flange portion integrated with the web portion so as to protrude in the transverse member connecting direction. And the web portion is substantially equivalent to the crosspiece shape of the crosspiece connected to the pillar (usually, a cross section of 105 to 120 mm square) or slightly smaller (ie, approximately 105 to 120 mm × horizontal). 2), and 2
Approximately 4 bolt insertion holes are drilled at predetermined intervals in the vertical direction, and are matched with the bolt insertion holes of the pillar material drilled in accordance with it, and both are crossed and penetrated with fixed bolts and nuts. It is connected to and integrated with a predetermined portion of the side of the pillar.

On the other hand, the metal fitting main body flange portion is bent and formed or welded from the flange portion in the direction of the transverse member to be connected, and is integrated into a protruding shape. And a substantially "T" -shaped, "L" -shaped, roll-over "U" -shape or "E" -shape, and the protruding width dimension is the wood required for fastening the horizontal member bolts. It is set in consideration of the fiber direction shear strength, and usually, two rows of bolt insertion holes are formed within the set width at least at a predetermined interval in a direction away from the web portion. Any one of the rows, preferably the one on the tip side
The bolt insertion hole group of the row has at least one wedge hole having a substantially side-down waterdrop-shaped contour which narrows in a direction away from the web portion, and is formed to have a lateral width larger than a cross section of the fastening bolt with an open upper end. Notch receiving holes (therefore, the uppermost bolt insertion holes in the group of bolt insertion holes in that row will be deformed and machined, and will not be holes in the strict sense). Must.

Incidentally, in the bolt insertion hole group of the row including the wedge holes and the notch receiving holes, all the bolt insertion holes except the notch receiving holes can be wedge holes. It should be formed so that only the length in the direction of the constriction shape is slightly different, and the position of the substantially circular hole on the web portion side should be aligned with the position where the fastening bolt is actually inserted. However, other than that, if necessary, the length of the wedge hole may be divided into a plurality of sets, or may be formed to have the same length.

In addition, the notch receiving hole temporarily holds the horizontal member by placing a hanging piercing metal penetrated through the bolt insertion hole of the horizontal member formed corresponding to the notch receiving hole.
An alignment pin is driven into the wedge hole to forcibly pull the horizontal member toward the column, and is formed into a shape and a width dimension such that horizontal movement can be finally performed to a predetermined position. In addition, for convenience of horizontal movement, for example, the bottom of the notch receiving hole, the part where the hanging piercing metal fitting is placed is slightly inclined downward toward the column material side Further, if the horizontal width is the same as or slightly larger than the longest dimension of the plurality of wedge holes described above, and is formed just above the wedge holes, the horizontal member can be formed. At the stage of temporary holding, the bolt insertion hole that is drilled at a predetermined position of the horizontal member and that corresponds to the wedge hole is always temporarily held in a state desired by the wedge hole. It becomes possible and convenient.

The positioning pin has a taper at least at its tip and has a length substantially equal to the diameter of the fastening bolt and substantially equal to the width of the cross section of the cross member (more precisely, from one side of the cross member, At least all of the connecting longitudinal grooves to be described later are penetrated, and the length of the tapered portion can exceed the innermost connecting longitudinal groove.)
If necessary, the side opposite to the taper forming side, that is, the head protrudes to the periphery like the head of a bolt or nail, and has a shape convenient for driving into a wedge hole Or, once it has been driven into the wedge hole, is not pulled out and replaced with a binding bolt, but instead becomes a part of another binding bolt and is inserted as it is, it is used as a retaining stopper. Irregularities and other friction portions may be formed at appropriate locations on the outer peripheral surface.

The hanging piercing fitting is transversely penetrated through a bolt insertion hole of a transverse member drilled corresponding to the flange cutout receiving hole of the above-described interrupt fitting body, and is provided on both sides of the transverse member. A length just enough to project its end from the surface,
When each protruding end is lifted as a support part, it must be formed to have both the strength and the shape such that it is not deformed by the weight of the transverse member or cut into the bolt insertion hole. However, the present invention is not limited to the case where the lifting arms with through holes are combined at both ends as in the embodiment described later, but the ring and the hook which are convenient for the lifting operation are formed. ,
In some cases, both ends remain straight, adopt a double-ended bolt that is threaded in a predetermined range, and use it by screwing a nut appropriately, or use a wire on the threaded part as it is Such a configuration can be adopted.

The column members and the horizontal members of the frame structure connected by the above-mentioned fittings are formed of natural wood and / or laminated materials conventionally used in the frame construction method and the like. While the predetermined position of the side surface, i.e., the connection forming position, the column member bolt insertion hole is previously formed at a position corresponding to the bolt insertion hole of the above-described connection fitting metal body main body web portion,

It is assumed that the cross member bolt insertion holes are formed in advance in a transverse manner, and each of them is carried into the site.

Using the metal fittings having the above-described structure as a basic structure, a wooden framed material is formed as follows. That is, the bolt insertion hole of the bracket main body web portion,
By combining a nut with a fixing bolt having a bolt insertion hole formed in accordance with the position and having a bolt insertion hole penetrated, the interruption metal fitting is connected and fixed to a predetermined position on the side surface of the column material. On the other hand, a connecting vertical groove is formed in advance in the horizontal member to be connected in accordance with the position of the metal fitting main body flange portion and the projection width from the opening, and the horizontal member is previously set in accordance with the position of the flange bolt insertion hole. Bolt insertion holes are formed, and the penetrating hanging brackets are inserted into the horizontal member bolt insertion holes and the horizontal member bolt insertion holes corresponding to the notch receiving holes in the bracket main body flange bolt insertion hole group. After suspending the transverse member above the interrupting fitting by using both ends of the suspending piercing fitting projecting from both side surfaces of the transverse member, the connecting vertical groove formed in the opening of the transverse member is inserted into the fitting body of the interrupting fitting. When the hanging piercing fitting is fitted to the flange and descends until it is placed in the notch receiving hole of the fitting main body flange, the horizontal member is temporarily held by the interruption fitting.

By temporarily holding in this manner, all of the bolt insertion holes corresponding to the horizontal member are respectively inserted into the bolt insertion holes of the metal fitting main body flange portion of the interruption metal fitting which is fixed at a predetermined position on the side surface of the pillar member. In addition to the substantially matching shape, the horizontal member bolt insertion corresponding to the wedge hole (or the optimum wedge hole among those provided with a plurality of wedge holes) in the bracket body flange portion bolt insertion hole group. Insert the alignment pin through the hole, make sure that all of the horizontal member bolt insertion holes are correctly aligned with the bolt holes in the flange main body flange of the interruption metal fittings, remove the hanging piercing metal fittings, and then insert the alignment pins. Through the other bolt insertion holes that do not have a fastening bolt / nut or alignment pin,

The bolts and holes are drilled beforehand in the material and the horizontal material by factory processing, and the connecting material is also cut into the horizontal material and cut into the site. After the column members are erected and temporarily fixed at predetermined positions on the base, a connection of a wooden frame structure is formed in accordance with the above-described connection forming method procedure of the present invention. However, the fixing of the interrupting fitting to the predetermined position of the pillar member may be performed at the factory processing stage or at an appropriate stage after being carried into the site as long as it is after formation of the bolt insertion hole.

In the case where a plurality of wedge holes are provided in the flange portion of the metal fitting main body as the interrupting metal fitting, a wooden frame structure having the above-described basic structure of the present invention is used. The connection forming method is to lift the horizontal member to be connected, temporarily hold the penetrating metal fitting for mounting in the notch receiving hole of the metal fitting main body flange portion, and then correspond to the plurality of wedge holes. The alignment pin is first passed through the horizontal member bolt insertion hole corresponding to the wedge hole with the largest overlap with the horizontal member bolt insertion hole, and the horizontal member is forcibly pulled in the column direction, and then overlapped Another alignment pin is passed through the bolt insertion hole corresponding to the wedge hole whose condition has become larger, and the horizontal member is further forcibly pulled in the column direction.
