Description

Detailed Description of the Invention (Object of the Invention) This invention relates to a new joint structure used in a wooden frame structure, and is based on the patent application No. 1985, which has already been developed by the applicant. This was developed in connection with the No. 42062 invention.

(Prior Art) In view of the current situation where the number of buildings with wooden framework structures has been sluggish, the applicant of this application has filed a patent application filed in 1986-3.
As has already been developed and completed with the No. 697 invention, etc., its cross-sectional area is approximately 41 cm (compared to the previous mark γI, which has a member size of 10.5 cm square).
By adopting a frame member equivalent to a 21cm square member, in particular a through column, and realizing an innovative wooden frame structure in which the column base is directly embedded and fixed in the foundation, the foundation and We were able to strengthen the bonding strength with the frame structure, eliminate reinforcing intermediary members by using large cross-section members, and simplify the construction process.

In order to make this basic structural form more practical, we are proceeding with improvement and development not only in the overall structural form but also in each part, with the aim of further improving the technology.

The above-mentioned invention in Japanese Patent Application No. 60-42062 was also realized in this process, and in particular, it was a new proposal regarding the attachment structure between the through columns and the horizontal members, that is, the shikuchi structure in the overall structural form. We have tried this method, and it has already achieved a level of effectiveness that was unachievable with previous products in terms of ease of assembly, ease of cutting, and strength of joints.

This invention has been developed and completed in order to further improve the Shiguchi structure, which has already been developed and put into practical use, and to make it even more practical. Its structure is detailed below. It is as expected.

(Structure of the Invention) As can be clearly understood from the representative embodiments shown in the drawings, the joint structure of the present invention basically consists of a wooden connecting member 3, a joint part 11 of a through-post 1, and a horizontal member. 2, the joint part 21, the wedge material 4,
This is realized by the plug 5.

First, the wood "A" connecting material 3 is made of straight natural wood or laminated wood, and a stopper hole 31 is inserted laterally through the member from the side surface near the end of the material. 31 is formed, and the top or bottom surface of the central part (of the pair of wooden joints 3, 3 used crosswise in a phased manner, the top surface for the top joint 3, and the top surface for the bottom joint 3). A notch 32 for engagement with a predetermined width is formed on the lower surface).

The joint portion 11.11- of the through post 1 is formed such that insertion holes 12.12' having a cross section longer than the cross section of the wooden connecting material 3 intersect with each other in vertical phase.
Relatively shallow mortises 13 and 13- are formed at both ends of the cross-members 2 and 12- to allow insertion of the entire cross-section of the butt end of the horizontal member 2.

The joint part 21 of the horizontal frame member 2 has a planar shape that is approximately half of the planar shape of the wooden joint material 3, and has two joints corresponding to the plug holes 31 and 31 of the wooden joint material 3. Plug hole 22.2
A mortise hole 23 formed in the middle of each of the mortises 2 is inserted into the upper end surface or the lower end surface of the butt end (of a pair of wooden joints 3, 3 used crosswise in a phased manner, the connecting material 3 is located on the upper side). It is formed to a predetermined depth so as to reveal its planar shape (the upper end surface of the horizontal member 2 that fits together, and the lower end surface of the horizontal member 2 that fits the connecting member 3 located below). It is.

The wedge material 4 has a thickness cross section that is slightly larger than the longitudinal dimension difference between the cross section of the insertion holes 12, 12- in the joint portion 11.11- of the through post 1 and the cross section of the wooden connecting material 3,
By being inserted into the insertion holes 13, 13- of the middle opening part 11°11' of the through-forest, the wooden connecting material 3 is pushed up or down (a pair of wooden connecting materials 3.3 used in a phased manner).
Push up against the connecting material 3 located on the upper side of the middle, push down against the connecting material 3 located on the lower side), pass through the interlocking part 32 of the wooden connecting material 3, and enter the mortar opening 11.11''. It performs the function of interlocking and connecting and integrating the wooden connecting material 3 to the through-post 1.

The plug 5 is driven between the plug holes 23 and 32, which correspond to each other and form one through hole.
Through this intervention, the wooden joint vi3 and the horizontal frame member 2 are integrated.

In addition to the rectangular cross-sectional shape, this stopper 5 can also have a circular cross-section, and when a circular cross-section is adopted, it is better from the viewpoint of resistance to shear failure. This has been experimentally proven through strength tests of Shiguchi IM construction. .

Toshisha 1 is a wooden pillar with a relatively large cross section, for example, 2"Icm square (7 inch square), and it does not matter what material it is made of, such as natural wood or laminated shrine.The base of the pillar is not particularly shown in the illustration. However, it is convenient if it is fixed to the foundation of the building in an embedded manner (usually fixed via a column base fixing fitting that is buried and fixed in advance in the foundation).

The horizontal members 2 include all the members other than the pillars constituting the framework, such as girders, footings, and sills, as well as the shelving and beams. The cross-sectional dimension is at least the width dimension of the through column 1.
For example, if we take a trunk insert as the horizontal member 2, the most commonly adopted size is about 12 cm (4 sun) in width and about 36 cm in height.
rm (1 shaku 2 sun) or the like, and the entire cross section of the butt end must be able to be completely inserted into the side surface of the through post 1 at the location where the joint portion is planned to be formed.

The horizontal members 2, which are inserted and connected oppositely to the through-posts 1, are tied and integrated by the wooden connecting members 3 that pass through the through-posts 1, but the joint parts of the through-posts 1 are When the horizontal members 2, 2, etc. are connected vertically and horizontally to the planned formation location, the wooden connecting materials 3 will be arranged vertically and horizontally in an intersecting manner, so they will be out of phase vertically. It is planned to pass through Toshisha 1.

Fig. 1 is a partially exploded perspective view showing a joint structure realized from the above configuration, Fig. 2 is a horizontal sectional view of the main part, and Fig. 3 is a horizontal sectional view of the main part.
The figure is a longitudinal cross-sectional view of the main part.

Although a building realized by adopting the joint structure of this invention can achieve a structure that does not require braces in terms of structural strength, it does not comply with the current building regulations and other regulations. In order to clarify the situation, although not shown in the drawings, supplementary braces may be provided to realize a wooden frame structure having a configuration similar to that of the present invention.

On the other hand, from the viewpoint of structural strength in the horizontal plane, each joint part has
As in the past, it is possible to realize a structure that deals with deformation in the horizontal plane by arranging flint beams, but in some cases, floor structure panels may be installed directly between the adjacent horizontal members 2. (not shown), it is possible to realize a framework structure in which the installation of the flint beams is completely omitted.

Each member formed in the above configuration is first placed in a grid-like arrangement according to a predetermined plan view, and the pillars 1, 1, . . .
In the process of temporarily attaching and erecting ..., the joint part 1 of each through-post 1
1. Insert the wooden connecting material 3 into one of the insertion holes 12 made at 11-, and fit it so that both ends protrude from the through-post 1. Subsequently, the other main shedding material 3 is inserted in the same manner from the insertion hole 12' of the intended one, and is fitted.

After that, the lower end or upper end of each insertion hole 12.12- (in the pair of crossed insertion holes 12, 12'', the lower end of the upper insertion hole 12, and the upper end of the lower insertion hole 12-) The lower surface or upper surface of the wooden connecting materials 3, 3 that are already in a fitted state (the lower surface of the connecting material 3 located on the upper side of the pair of wooden connecting materials 3.3 used in a phased manner, Forcibly drive in the IJ connectors 3 and 3 between the lower and the upper surface of the connecting material 3, and make sure that each tree! IJ connecting material 3. Fix it so that it matches the core.

As a result, each of the wooden connecting materials 3, 3 is vertically phased and intersecting, and both ends of each wooden connecting material 3, 3 have equal lengths in the front, back, left and right directions of the through-post 1. It becomes protruding.

The joint parts 21 of the horizontal frame members 2 to be connected are fitted to each end of the wooden connecting members 3 which have become protruding in this way, and then the horizontal frame members 2
Completely insert the end of the wood into the mortise 13 formed at the end of the insertion hole 12. Then, the plug holes 22, 31 of the wooden connecting material 3 form a single hole, and when the plug 5 is driven into the hole, each of the horizontal members 2, 2...・ are firmly tightened and fixed via the wooden connecting material 3 that penetrates and fits through the through post 1 with the ends of the ends fitted into the mortises 13 of the through post 1, and the wooden structure of this invention Completed the Shiguchi structure in the framework structure.

It goes without saying that the procedure for assembling the joint part is not necessarily limited to the procedure described above; for example,
Before temporarily attaching and erecting the through-post 1, the wooden connecting materials 3, 3 are accurately fixed to the joint part of the through-post 1 on the ground in advance, and
The most suitable procedure can be adopted depending on the situation, such as handling the building, or connecting and fixing several horizontal members 2 on the ground, and then erecting the building.

In addition, in the above embodiment, horizontal members 2 are provided around each through-post 1.
, 2 are connected and crossed.
In addition to being possible to implement based on the same idea even when connecting in a letter shape, it is also possible to adopt the same method even when the cross section of the through column is not a normal square cross section.

(Function and Effect) The joint structure in the wooden frame structure of the present invention having the above-mentioned configuration is @
This is realized by a complete insertion-fitting structure of the entire cross section of the end of the frame members 2, and is firmly connected by the wooden connecting material 3 of the same quality as each frame member, and the connecting material 3 is on the end side of the horizontal member 2. One side of either the top end or the bottom end (in most cases,
It appears only on the surface that forms the wall and becomes hidden (
Even in this case, it looks like wood of the same quality has been embedded, and there is no sense of discomfort at all), so the intersection of the through column 1 and the horizontal member 2 has a very clean structure, and even if it is an exposed joint part, it does not look like any design. Not only does it have no problems in terms of effectiveness, but it can even be said to be a good enough shiguchi part to be used as is to enhance the aesthetic effect.

Another effect is that as the through columns 1, horizontal members 2, and wooden connecting members 3 are all made of wooden materials, the deformation stress due to external force applied to the joint part is approximately equalized, and each component This means that the joint parts do not deform and move individually, and are much more reliable, especially compared to those that used conventional fastening fittings. Therefore, with the conventional product, wobble would occur at the joint unless additional seaming work was done mid-way, but with the product of this invention, there is almost no such worry and the finish is strong. It is possible to realize the mouth structure.

In particular, the shape of the insertion hole 12 formed in the through-post 1 and the shape of the wooden connecting material 3 were changed to
- Since it is made simpler than the one devised in No. 42062, it is not only easy to combine with the wooden material 4 and the plug 5, but also the processing of each component is easy. The effect can be said to be extremely significant.

Additionally, what should be noted is that the integration of the horizontal member 2 with the wooden connecting piece 3 in this invention has a structure in which the stopper 5 can be driven in from the horizontal direction. Firstly, on-site work can be carried out extremely safely and quickly, and secondly, even if the joint part is deformed due to external force, it will never occur that these plugs 5, 5...
Thirdly, if the cross-sectional shape of the stopper 5 and the stopper through hole 22.31 is restricted to a circular cross-section, there is no risk of the center falling off. In comparison, the shear stress is greatly increased, and a more reliable joint structure can be realized.

In addition, in order to integrate the stopper 5, the frame structure must be dismantled and moved for some reason (in some cases, the conventional joint structure using metal fittings or the traditional notch structure) Unlike the case of the opening structure, it can be disassembled extremely easily, and it goes without saying that the necessary expenses can be greatly reduced.
The through-pillar 1 has an excellent feature of being fully reusable because it is not damaged in any way.

As shown diagonally above, the wooden frame 1 of this invention? is 'r'M
The Shiguchi structure in the present application is a wooden framework with embedded column bases that employs relatively large cross-section members (M-structure), which has been widely demonstrated since the applicant Yama et al. In addition to solidifying the strength, it contributes to improving economic efficiency through improvements in workability, standardization of components and construction methods, and increases work safety and the structural strength of the joint structure, as well as improving architectural style. The effect of revitalizing the slumping wooden architecture can be enormous, such as greatly increasing the IQ of the upscale buildings.
