2. Description of the Related Art Since ancient times, Japanese wooden frame structures have been highly evaluated as one of the most outstanding wooden construction styles in the world due to their completed joint structure and joint structure. The existence of a carpenter who is skilled in advanced incision processing is an essential factor in realizing a special joint structure and joint structure. However, along with the passage of time, the popularity of this field from young people has disappeared, and the training of skilled young workers has become unavoidable.In addition, carpenters who have been active in this field for many years are aging. Therefore, the absolute number of carpenters who can realize the unique joint structure and joint structure of Japan is decreasing with the years.

Under such circumstances, the wooden frame structure has been replaced by the traditional wooden structure of Japan, and the time has come to see the rise and prosperity of wooden structures and various prefabricated structures by, for example, the two-by-four method, which do not require special skilled craftsmen. ing. However, even among these general trends, there is still a strong tendency to seek peace of mind in traditional architectural styles up until now, and in addition to the recovery and development of Japan's economy, the prefabricated buildings that are in fashion nowadays have become popular. It is also true that more and more people are choosing to use traditional Japanese wooden frame structures without accepting them. In view of such recent trends, the applicant of the present application has already made some proposals as a countermeasure, and some of them have already been put into practice.

The invention of Japanese Patent Application No. 119482 of 2003 is also one of the technical ideas that the applicant of the present invention has realized in such a series of flows, and in particular, the stigma part in a wooden frame structure. Regarding the joint structure of, the traditional wooden structure of the through pillars and the horizontal bridges are connected and combined with a special joint, and the horizontal pillars are used as the support parts to stand the wooden pillars on the upper and lower floors except the through pillars. It proposed that the existing architectural style could be rationally removed.

The present invention is based on yet another technical idea completed for the same purpose as the above-mentioned invention. First and foremost, the most important problem is the upper and lower wooden pillars which cannot be realized by the above-mentioned invention. At the same time that they are directly connected to the stigma and pedestal, the metal fittings used to connect them are exposed at the protruding corners of the wooden pillars (the corners between the intersecting horizontal members). The present invention intends to realize a joint structure that does not hinder the subsequent formation of the finishing structure as much as possible, and the structure thereof is as described in detail below.

DETAILED DESCRIPTION OF THE INVENTION The stilt joint structure of the wooden frame structure of the present invention represented by the embodiment shown in the drawings basically has the following structure.

[0006] That is, the wooden columns 1 and 1 which are formed to have a length according to the frame height of a horizontal member for a shed or an upper floor.
, And the fixing members 61, 61, ... such as bolts and nuts are directly connected to each other in the vertical direction and integrated with each other, and on the side surfaces of the wooden columns 1, 1 connected to the vertical direction. The exposed strip members 6, 6, ... Retaining material 2 for connecting the main horizontal member 3 to the wooden pillar 1 stilts, and the spacing member for securing a working space on the main horizontal member 3. A stilt joint structure of a wooden frame structure is characterized in that it is covered with the auxiliary horizontal member 4 which is integrated via 5, 5 ,.

The wooden pillar 1 is a pillar made of so-called cypress, cedar, rice bran, etc., which has a size of 105 mm (3 inch) square, 121 mm (4 inch) square or more, which has been adopted so far. Yes, from the foundation or foundation, the horizontal cross members 3 that will form the hut, that is, the frame height of the shed beams and eaves girders, or the second floor and the third floor in the case of a structure with two or more floors. A horizontal member 3 that constitutes a floor assembly structure such as a floor, that is, a beam, a girder,
It is formed to have a length according to the height of the frame such as a girth. Therefore, it is possible to handle not only a one-story house but also a two-story structure by standardizing the frame height of each floor so that the length of the wooden pillar is standardized to a standard length.

It is the strip member 6 that fulfills the function of vertically connecting the wooden columns 1 and 1, and is made of a strong material such as a thick steel plate, and is a bolt / nut for fixing the wooden columns 1 to each other. Through holes 6 for inserting fixing metal fittings 62 and the like, and tight fitting metal fittings 8 for tightly connecting L-shaped members 7, 7 described later.
, 61, ... Are formed in an elongated shape which is preliminarily formed in a predetermined manner. The strip members 6, 6, ... are attached to the side of the stigma of the wooden pillar 1, and approximately half of the total length of each of the strip members are projected upward from the stigma of the wooden pillar 1, and first fixed to the stigma side. It is fixed with metal fittings 62, 62, ...
The column base of the wooden column 1 to be connected is dropped from above and fixed with fixing fittings 62, 62, ... such as bolts and nuts, and the strip members 6, 6, ... are the wooden columns 1 on the lower side. Wooden pillars 1, 1 in a state where they straddle the stigma and the wooden pillar 1 on the upper side
Are directly connected to each other.

The receiving member 2 is a stigma of the wooden pillar 1, and is attached to a side surface facing the connecting direction of the horizontal members, which is a pair of the main horizontal member 3 and the auxiliary horizontal member 4, and is attached as necessary. In addition to using an adhesive,
Fixed with fixing members 22, 22, ... such as bolts and nuts,
Be integrated. The receiving member 2 supports the main horizontal member 3 on the stepped jaw portion 21 and supports the auxiliary horizontal member 4 at the upper end of the same, and at the same time, the surface on which the step member is not formed, that is, the wooden pillar 1 The upper side of the surface that abuts on the sheet has a function of covering the above-mentioned strip member 6 excluding the height dimension of the auxiliary horizontal member 3 from the upper end. If necessary, an appropriate means for easily aligning the axis of the main horizontal member 3 with the core of the wooden column 1 may be provided at a suitable place of the stepped portion, such as a dowel. It is assumed that a simple adjustment process such as a ridge or groove is applied, and a processing part to be fitted to it is formed at the corresponding part of the main horizontal member 3, and if they are matched, it is automatically It is also possible that the centering is realized.

The horizontal member is composed of a combination of a main horizontal member 3 and an auxiliary horizontal member 4 which is juxtaposed above the main horizontal member 3 with a work space portion at a predetermined interval therebetween. The space retaining member 5 for securing the parts is interposed, and then the binding member 9 constitutes a substantially integral horizontal member, which is attached to and integrated with the stigma as described above. The stepped jaw portion 21 of the receiving member 2 and the upper end wooden mouth are indirectly joined around the upper and lower connecting portions of the wooden columns 1 and 1 as a supporting portion. , When the wooden pillar 1 is joined from only one direction, when joined from two opposite directions on the same axis, the joints are made from two different directions (if the wooden pillar 1 has a quadrangular cross section, L In the case of letter-joining), or one side of a wooden pillar is left (the wooden pillar 1 is a square section). If it is joined in the direction toward the pillar core in the direction of three planes, that is, in the direction of the letter T, or again, the entire side surface of the wooden pillar 1 (if the wooden pillar 1 has a quadrangular cross section, a figure of ten) Various modes such as the case of joining toward (to be joined) are included.

Among them, the main horizontal member 3 is a structural member that receives the horizontal proof stress of a so-called wooden structure and bears a floor load. Structure, for example, the receiving member 2 is the stepped portion 1
1 If it is attached to the entire surface, it will be a mortar, and if the receiving member 2 is about half of the horizontal member 3, it will be a stool joint to realize the connection to the pillar 1. that time,
In order to prevent it from slipping out in the horizontal direction, the main horizontal member 3
Of the L-shaped member 7 integrated so as to be accommodated in the work space S, the upper surface near the end on the joining side of the strip member 6, or on the opposite side on the same axis. In the case of the structure in which the horizontal members of
The wooden post 1 and the strip member 6 are penetrated and crossed between the web portion 71 and the web portion 71, and the binding metal fitting 8 is arranged to realize the binding.

On the other hand, the auxiliary horizontal member 4 is provided with the space members 5, 5, ...
In addition to the function of supporting the joist ends of the 2nd floor and 3rd floor like a traditional joist and serving as the abutting surface of the prefabricated panels for 2nd and 3rd floor, The end portion on the joining side is placed on the upper end wooden mouth of the receiving member 2 which is already integrated with the stigma of the wooden pillar 1, and the strip member 6 protruding above the receiving member 2 by its own wooden mouth. It will fulfill the function of concealing.

The spacing member 5 may have a height (usually around 10 cm) comparable to the protruding size of the receiving member 2 protruding from the top end of the main horizontal member 3 and its thickness. Then, one side of which must be at least as thick as the thickness of the horizontal member 3 and has a cross-sectional size that does not hinder the penetration of the binding metal 9, and in particular, an existing floor panel (Fig. In the case of a structure adopting (not shown), such a size that the spacing members 5, 5, ... Only project from the side surface of the horizontal member 3 in order to support the edges of the existing panels. In some cases, a large member having a size (at least about 2 to 3 cm protruding from one side surface of the horizontal member) is used.
In the above description of the basic configuration of the present invention,
The reference numerals given to the respective constituents are for convenience only for the purpose of facilitating the correspondence with the embodiments, and the structure and the like of the respective constituents are not restricted by this. An embodiment of the most typical joint structure based on the technical idea of the present invention shown in the drawings will be explained below.

[0014]

[Embodiment 1] An exploded perspective view showing the connection relationship around the wooden columns 1 and 1 joints of FIG. 1, a partially exploded perspective view of the state immediately before completion of FIG. 2 seen from another angle, and a central part of FIG. The stigma connection structure shown in the vertical cross-section is a wooden pillar with one stilt, and the main horizontal members 3,3 around the joint that directly connects the one wooden pedestal on the upper floor.
Fig. 4 is an example of a stigma connection structure in the case where a horizontal member which forms a pair with the auxiliary horizontal members 4 and 4 (that is, a horizontal member which becomes a beam and a girder) is joined from two directions orthogonal to each other. A structure in which the top ends of the horizontal members (to be precise, the top ends of both the main horizontal members 3, 3 and the auxiliary horizontal members 4, 4) are accommodated in the same horizontal plane is realized.

First, as shown in the exploded perspective view of the exploded perspective view of FIG. 1, a main horizontal member 3, which is a horizontal member for the upper floor, is formed.
3 and the strip member 6 on each side of the stigma of the wooden pillar 1 formed to have a length dimension corresponding to the frame height of the auxiliary horizontal members 4 and 4 arranged side by side with the working space S secured thereabove. , 6, ……
However, about half of the length is integrated so as to project upward from the stigma. The strip members 6 are used on the surfaces facing the stigmas, and the same position is that the through holes 61, 61, ... Are formed at exactly the same position. , 61, ... are fixed members 62
It is formed by phasing by a dimension slightly larger than the thickness of. (This structure can be realized by preparing two types of strip members 6, but in this example, the through-hole forming positions are automatically phased by simply reversing the same type. In order to avoid
1, ... The ones that are formed with consideration for the formation position are used. )

Next, among the strip members 6, 6, ..., 2 which are adjacent to each other and are orthogonal to each other, which are the connecting surfaces of the horizontal members which pair the main horizontal members 3, 3 and the auxiliary horizontal members 4, 4. From the outside of the strip members 6 and 6 fixed to the surface, the receiving members 2 and 2 formed in a stepped shape over the length range of the height dimension of the horizontal member to be abutted.
The upper end of the strip member 6 and the upper end of the strip member 6 and the auxiliary horizontal members 4 and 4 with the heights of the respective mouths of the auxiliary horizontal members 4, 6 Turn into.

In this embodiment, since the strip members 6 and 6 project from the side surface of the stigma by the amount corresponding to the material thickness, the contact surface sides of the receiving members 2 and 2 are formed with the groove portions capable of absorbing them. Therefore, in the structure in which the fixing members 22 and 22 are regulated and integrated as described above, there is no gap between the wooden columns 1. Strip members 6, 6, ... and supporting members 2, 2, ... that are regulated and attached so as to partially cover them
The wooden pillars 1, 1, ... may be set up one after another while standing on the construction site, and they may be fixed together, but up to that point, the horizontal crossing materials shown in the beam or floor plan. Depending on the connection direction of the, the wooden pillars 1,1, ...
As a matter of course, it is not suitable even if it is produced in a factory and brought into the site for use.

Subsequently, the wooden pillars 1 for the roof or upper floors
, And the fixing members 62, 62 are used to drop the leg portions of the strip members 6, 6 ,.
Integrated structure by directly connecting the wooden pillars 1 and 1 to each other (that is, the connection of the stile head of the wooden pillar 1 on the lower floor to the pillar base of the wooden pillar 1 on the upper floor) To realize. On the other hand, on the stigma of the wooden pillar 1 to which the receiving members 2 and 2 are attached in a predetermined direction, the main main cross members 3 and 3 are planned.
Are to be connected by hoisting them with a crane. On the upper surface in the vicinity of the connection-side ends of the main horizontal members 3 and 3, an L-shaped member 7 is provided on the ground portion and a plurality of fixing members 72, 7 are provided.
2, ... is firmly attached, and after being connected to the stepped jaw 21 of the receiving member 2 as a mounting state, the L which has been previously integrated is attached.
The web portion 71 of the mold member 7 is inserted from the side of the strip member 6 which is the outside of the strip members 6 and 6 on the axis of the horizontal member (that is, the side which is not covered by the receiving member 2). The wooden columns 1 are tightly connected to each other by tightly connecting members 8 to realize a structure in which the horizontal movement of the main horizontal member 3 is reliably prevented.

In this embodiment, since the horizontal member is connected to the wooden column 1 in an L shape in plan view, the horizontal movement of the main horizontal member 3 is as described above. The example in which the binding member 8 is arranged between the strip member 6 and the web 71 of the L-shaped member 7 is, for example, the connection between the horizontal members which are straight in the planes which face each other with the wooden pillar 1 sandwiched therebetween. At the location, the binding member 8 penetrates the binding member 8 between the web portions 71, 71 of the L-shaped members 7, 7 integrated on the upper surfaces of the respective main horizontal members 3, 3 (of course, the strip members 6 facing each other). , 6 and the wooden pillars 1 between them are pierced) and tightly connected.
In this embodiment, a ridge 23 for centering is formed on the rising surface of the stepped portion of the receiving member 2, and the contact side mouth of the main horizontal member 3 is provided with a concave portion to be fitted thereto. Grooves 33 are formed, and when they are fitted together during assembly, the axis of the main horizontal member 3 automatically coincides with the core of the wooden column 1, and there is no need to perform centering work for both afterwards. This is an example.

As described above, each wooden pillar 1, 1, ...
When the main horizontal members 3, 3, ... are horizontally installed and fixed around as specified, the respective wooden columns 1, 1, ... are basically (ie,
(Except in the case of a mezzanine structure and other structures where the floor height is intentionally changed for some reason, etc.), a structure in which all the upper surfaces are within the same horizontal plane will be realized. . After that, the spacing members 5, 5, ... Are arranged on the upper surfaces of the respective main horizontal members 3, 3, ..
3, ... Auxiliary horizontal members 4, 4, ... are horizontally installed and integrated so that the work space S is secured on the upper surface. Thus
Around the wooden pillars 1, 1, ..., a horizontal member which is a pair of a main horizontal member 3 and an auxiliary horizontal member 4 is vertically connected while the working space S is secured. , 1 is directly connected in the vertical direction to realize a joint structure.

At this time, the connecting side end portions of the auxiliary horizontal members 4, 4, ... Are placed on the upper end opening of the receiving member 2 and at the same time, the auxiliary horizontal members 4, 4 ,. At the mouth of the strip, the strip members 6, 6, ... that appeared on the side of the column base of the wooden column 1 on the upper floor will be covered up nicely. The process of assembling the constituent members of the joint structure according to the present invention is not necessarily limited to the above-mentioned process. For example, the main horizontal member 3 and the auxiliary horizontal member 4 may be attached in reverse order. Instead, the work space S can be used to carry out the tightening of the tightening members 9 later, and the main horizontal members 3,
3, ... Wooden columns 1, through all receiving materials 2, 2, ...
1,… After connecting around, wooden pillars on the upper floor 1, 1,…
It is also possible to freely adopt a work process in which the column base of ... is dropped between the strip members 6, 6, ... so as to be fixed.

[0022]

In the stigma connection structure of the present invention having the above-mentioned structure, the stigmas of the wooden pillars 1 on the lower floor and the pedestals of the wooden pillars 1 on the upper floor or the shed are directly connected. We have completed an excellent framework structure that realizes the structure and makes it possible to transmit axial strength downwards extremely smoothly, and at the same time, the strip members 6, 6 ... However, the supporting members 2, 2, ... are arranged in a restricted arrangement around the stigmas, and the main horizontal member 3 and the auxiliary horizontal member are arranged in a predetermined combination with respect to the supporting members 2, 2 ,. Since the horizontal members paired with 4 are connected to each other, they are not exposed inside at least the inside of the building. Therefore, the selection of the finishing structure after that, that is, the large wall structure, The degree of freedom in selecting whether to use a true wall structure or an open structure with no walls is extremely high. It is quite realized a novel Wooden structure that could not talk in the construction of up to previously that increase.

Further, since the wooden columns 1, 1 which are directly connected to the upper and lower sides have a structure in which the horizontal members are connected through the receiving members 2, 2, ... There is almost no need to perform the joint processing for attaching the wood on the side surfaces of the wooden columns 1 and 1, and therefore it is not necessary to consider the cross-section loss due to the joint processing of the wooden columns 1 and 1, so the structure up to now In order to avoid cross-section loss, it was physically impossible to align the upper surfaces of multiple horizontal members within the same horizontal plane due to restrictions on the connection position of the horizontal members around the same column. Unlike the above, it is possible to realize a structure that allows the upper surfaces of all the horizontal members to be housed in the same horizontal plane. As a result, in addition to the standardization of the wooden columns 1 and 1, the floor structure and the shed structure Becomes extremely orderly, and standardization of these members is possible,
Although it is a wooden frame structure, it enables simple and quick implementation of construction without special craftsmen, and leads to a compact floor floor space or attic space on each floor.
The eaves height of the entire structure can be kept low, and it has a remarkable effect that it has an advantageous effect on the construction of a three-story wooden frame structure which will become popular in the future.

Further, the horizontal member is not a pair of the main horizontal member 3 and the auxiliary horizontal member 4, and the main horizontal member 3 is made to function exclusively in terms of structural strength, and other members such as joist. The processing portion for receiving the members such as the sash, the hauling, and the striking beam is provided exclusively by using the auxiliary horizontal member 4 or the working space portion S. It is extremely easy to consider the cross-section loss of the frame material, and it also has the excellent feature that it is easy to realize a safe structure and secure the safety of extension and renovation at an appropriate time after construction. Become. In particular, in the case of the one representative of the present invention shown in the examples, the above-mentioned features are further promoted, and the wooden frame structure, which is considered to be unsustainable with the structure as before, does not substantially change its value. We guarantee that it will continue in the future.

As mentioned above, the stigma connection structure for a wooden frame structure of the present invention realizes a wooden frame structure from ancient Japan, as in some inventions already proposed by the applicant of the present application. In doing so, the construction efficiency can be improved without affecting the traditional structural form, and it can be made even more advantageous in terms of its structural strength. For those who want to keep it to the minimum possible, and who are not tired of prefabricated construction and expect the original wooden frame structure,
A high-quality wooden frame structure that can enjoy the advantages of a wooden frame structure makes it possible to reduce the economic burden as much as possible and meet the expectations.
