DETAILED DESCRIPTION OF THE INVENTION According to the present invention, a part of the connecting plate is inserted into a vertical groove provided in the horizontal plane of the upper end of the lower column, and is connected with nails or bolts so as to protrude. The end of the beam provided with a vertical groove is placed on the lower column by fitting the vertical groove into the protrusion of the coupling plate and bringing the lower horizontal surface into contact with the upper horizontal surface of the lower column, It relates to the structure of a joint between a column and a beam, which is characterized by being joined with nails or bolts.

Hereinafter, the present invention will be described in detail with reference to embodiments of the accompanying drawings.

The attached drawings, Figures 1 and 2, show an example of how two upper and lower pillars are connected to four beams, and a vertical groove provided in the horizontal plane of the upper end of the lower pillar 1 has a connecting plate 2 with a front shape.
The lower connecting piece is inserted and fitted, the nail 3 is driven from the outside of the lower column 1, the connecting plate 2 is connected and protrudes from the lower column 1, and a rectangular shape is inserted into the vertical hole provided in the center of the connecting plate 2. A connecting plate 2' is inserted through the connecting plate 2'. On the other hand, the ends of the four beams 4, 4, 4, 4, which have vertical grooves 4a on their side end faces and are obliquely cut on both sides of the ends, extend the vertical grooves 4a into the coupling plates 2 and 2', respectively. It is placed on the lower column 1 with the lower horizontal surface in contact with the upper end horizontal surface of the lower column 1, and a nail is driven from the outside of the beam 4. A book beam is connected to the connecting plates 2 and 2'. Further, the upper column 1' has a vertical groove provided on its lower end horizontal surface that fits into the upper connecting piece of the connecting plate 2, and its lower end horizontal surface touches the upper end horizontal surface of the four beams 4, 4, 4, 4. The upper pillars 1' are placed in a straddling state, and nails 3 are driven from the outside of the upper pillar 1' to connect them to the connecting plate 2. That is, the two upper and lower columns 1, 1' and 4
The book beams 4, 4, 4, 4 are connected via connecting plates 2 and 2'.

In the above example, the bonding plate is laminated plywood, synthetic resin,
Synthetic resin containing foamed fibers, metal-based or glass-based inorganic fibers, or natural fibers such as cotton, silk, and hemp bound together with a binder, and net materials made from the above fibers are laminated and cured with a mixture of wood flour and a binder. Those with high strength and suitable for nailing are used, such as those made by mixing the above fibers with wood flour and a binder and molding and hardening them. The method for producing the above-mentioned molded article is to stack the loosely entangled fiber sheets and a thermoplastic synthetic resin melt mixed with wood flour on a belt conveyor, impregnate them, and form them into a plate shape with rolls. A mixed layer of a net-like material, a thermoplastic synthetic resin or a thermosetting synthetic resin, and wood flour is laminated in multiple layers on a belt conveyor and formed into a roll plate shape, and then heated, cooled, or chemically changed. harden,
It can be made by cutting the plate material into the shape of the connecting plates 2, 2', inserting the connecting plates 2' into the vertical holes of the connecting plate 2, and bonding them with an adhesive. Further, when making the above-mentioned plate material, flame retardants, termite repellents, water glass, etc. may be mixed and molded, or laminated with aluminum foil or heat-resistant sheet via rolls and laminated. Further, the shape of the coupling plate 2 may be any shape, such as an octagon or a quadrangle. The exposed portion of the coupling plate having the above shape can respond to horizontal force, and the shape of the coupling plate can be changed in various ways depending on the number of columns and beams to be coupled. In addition, the gaps formed by the columns and beams may be filled or coated with cement mortar, wood powder, wood chips, etc. mixed with a binder or fibers, and the bonding plates 2 and 2' are made of metal. It is also possible to provide bolt holes in the structure and use bolts to connect columns and beams. FIG. 3 shows the combination coupling plates 5, 6, 7.8, and the combination plates 7, 8 may have notches provided in the coupling plates and the notches may be engaged with each other.

In the above embodiment, wood was used for the pillars and beams, but in this invention, the pillars are made of wood, and the horizontal members such as beams are made of metal such as channel steel, which are arranged on one or both sides of the connecting plate, and the bolts are They can be combined to form a frame consisting of wooden columns and metal horizontal members. In addition, to connect the foundation, foundation, and columns, anchor bolts are welded to the connecting plate and protruded from the foundation concrete, and the foundation and the columns or pillars above it are connected via the connecting plate. I can do it.

In conventional wooden construction, the joint between columns and beams is not only complicated and requires skill and time to carve, but also requires a mortise hole in the column and the tenon of the beam inserted into this hole, which results in insufficient joint strength. Moreover, there were drawbacks such as the inability to connect a beam in the middle of an upright column. In order to connect a beam to the middle of an upright column, the applicant proposed in Japanese Patent Application No. 113618/1983 that a connecting plate was provided protruding from the middle side of the column, and a vertical groove provided on the end face of the beam was fitted into this. However, the joint strength was not sufficient because the beam load was supported only by the joint handle, which was proposed. Further, as another method, the methods shown in FIGS. 4 to 8 can also be considered. The method shown in FIGS. 4 to 8 is as follows.

FIG. 4 shows a coupling tool 9, in which two notches 9d are provided at the bottom of a rectangular metal plate 9a, both sides of which are bent 90 degrees in one direction to form a beam mounting base 9c, and bolt holes 9d and nails are formed. A hole 9e is provided. As shown in FIG. 6, first connect the connectors 9', 9', which have two notches 9b' in the upper part of the connector 9, to the lower column 10.
The bolts 1 are inserted into the bolt holes provided in the coupling tool 9' and the horizontal holes provided in the pillar 10.
Connectors 9' and 9' are attached to both sides of the upper part of the column 10 by inserting the connector 1 and tightening a nut at its tip. Next, the upper column 10' is placed on the lower column 10 and connected with bolts in the same manner. Next, the connectors 9, 9 are dropped perpendicularly to the connectors 9', 9' on both sides of the joint part of the pillars by fitting their notches 9b into the notches 9b' of the connectors 9', and similarly. Connect with bolts. Next, the ends of the beams 12 are placed on the beam mounting base of each connector and connected with bolts, so that the four horizontal beams can be connected to the upper and lower columns as shown in FIG. In the above connection method, nails may also be used, and the beam mounting tables 9c, 9c may be connected with a connecting member 13 as shown in FIG. Furthermore, by using the coupling tool 14 shown in FIG. 5 and a coupling tool having a notch on the top, beams can be coupled in one to three directions. In addition, it is possible to connect the pillar 10 with beams in directions 1 to 4, and it is also possible to connect a beam in the middle of the pillar. Alternatively, the pillars may be made of wood, the beams and eaves beams may be made of metal, and the beams, etc., may be placed on a beam mounting table and connected with bolts. When using tall beams, the beams and the like may be clamped and connected by disposing coupling tools vertically facing each other.

The connection method shown in Figures 4 to 8 described above is a simple connection method that does not require cutting on columns and beams, and the connection strength is sufficient, but since the connection tool is exposed to the outside, this method There is an inconvenience in that it is not possible to nail interior or exterior materials to the area. However, since this invention is constructed as described above, the shiiguchi is simple and does not require much skill and time for carving.
The ends of the beams are placed on the lower pillars, the load is directly supported by the lower pillars, and they are connected with bolts, etc., so the joint strength is sufficient even though the joint is simplified, and the beams are directly above the pillars. It is possible to connect to an upright column by placing it on the lower column, which simplifies the assembly sequence of the frame frame structure, and because the connecting plate is not exposed to the outside, interior and exterior materials cannot be nailed to the joint. It has the effect of making it easier to hit.
