Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to architecture, particularly to a joint structure between columns and beams or girders in wooden architecture.

[Conventional technology]

Conventionally, as a connection structure between a column and a beam for wooden construction, for example, an inverted T consisting of a horizontal plate part and a vertical plate part is attached to the outer circumferential surface of a square pipe-shaped column fixing device that is fitted to a column.
By protruding a joint in the shape of a letter, the end of the beam is supported from below by the horizontal end of the joint, and the vertical plate is inserted into the vertical groove cut into the end face of the beam. A structure is known in which the vertical plate is joined with bolts (Japanese Patent Publication No. 60-18778, Japanese Patent Publication No. 18778,
58-56779).

[Problem that the invention seeks to solve]

By the way, in the conventional column-to-beam connection structure as described above, an inverted T-shaped connector consisting of a horizontal plate part and a vertical plate part that connects the ends of the beam material is integrally connected to the column fixture attached to the column. When manufacturing such coupling fittings in advance, it is difficult to connect four beams to a column, instead of one that connects one beam to a column. Up to the model that
It is necessary to prepare individual coupling fittings with different shapes depending on the number of beams, which poses a problem in that the manufacturing cost is relatively high.

Also, although we talk about joining columns and beams, in reality, depending on the location, the beams and girders that are connected to columns may not always have the same height as the beams on the right side of the column. First, when joining beams or girders of different heights to columns, it is inconvenient for the vertical plate parts of the inverted T-shaped connector to all have the same height, so the four types of connectors described above are used. This method alone cannot be applied to all construction sites, and there is a problem in that it is necessary to prepare other types of connecting fittings of the same type.

[Means for solving problems]

The present invention solves the problems with conventional joint structures as described above, and changes the structure of the metal fittings used to connect columns and beams to basic members that can be used in common to as many joint structures as possible. By combining this basic shape member with applied parts to be joined, and preparing applied parts in various shapes, it is possible to obtain a joint structure that can be applied to various models using low-cost parts. It is something.

In the present invention, as a specific means for the above-mentioned coupling structure, a cap material with a top plate fitted to the tip of a column, a square-shaped internal connecting material interposed inside this cap material, and an outer circumferential surface of the cap material are provided. The beam supporting material has a connecting surface with the outer peripheral surface of the cap material, side plates that clamp both sides of the end of the beam material, and a support plate that supports the bottom surface of the end of the beam material. The connecting surface of the beam receiving material is connected to the outer circumferential surface of the cap material with bolts through an internal connecting material inserted into the inner inner end of the cap material, and the column and the cap material are bolted to each other at the lower end of the cap material, The beam and the beam supporting material are characterized in that they are bolted to each other between both side plates on the supporting surface.

[Effect]

In the coupling structure of the present invention, a square-shaped internal connecting member is inserted into the upper end of the inside of the cap member in advance, and then this cap member is fitted to the upper end of the column. At the upper end of the inside of the cap material, a unique space is formed that is separated from the inside of the cap material itself by the square-shaped internal connecting material. By screwing toward the internal connecting member, the beam support member is connected to the outer peripheral surface of the cap member.

Inside the cap material, the lower part of the internal connecting member at the upper end is a space into which the upper end of the column can be inserted, so after inserting the upper end of the column into this part, the cap material and the column are joined with bolts. .

Since the beam support material is connected to the outer peripheral surface of the cap material as described above, the end of the beam material is placed in the space on the support surface between the both side plates of the beam support material, and the both side plates and the beam material are connected with bolts. Join.

The cap material 2 is made up of four outer circumferential surfaces 6 formed to have a rectangular cross section to fit on the upper ends of the pillars 1, and a top plate 3 provided at the upper ends of these outer circumferential surfaces 6. Four internally threaded bolt holes 7 are formed in the outer peripheral surface 6, and three bolt holes 8 and two bolt holes 9 are formed in the upper end and the lower end of each outer peripheral surface 6, respectively.

As shown in FIGS. 1 and 2, the square-shaped internal connecting member 4 is composed of four outer peripheral walls 10 and a bottom plate 11 each having an outer diameter that can be inserted into the inner periphery of the cap member 2. When the upper edge 10a of the outer peripheral wall 10 is in contact with the back surface of the top plate 3 of the cap material 2, three female threaded bolt holes 12 communicating with the bolt holes 8 in the outer peripheral surface 6 of the cap material and one in the bottom plate 11 are inserted. A bolt hole 13 is opened.

On the other hand, as shown in Figures 3a, b, and c, the beam support material 5 is made of several types of beam support materials 5 each having a slightly different shape depending on the height and shape of the girder and beam material 14 used.
a, 5b, 5c... are prepared. However, each of these beam support members 5 basically has a connecting surface 15 that comes into contact with the outer circumferential surface 6 of the cap material 2;
side plates 16 that clamp both sides of the end of the beam material 14;
They are common in that they are composed of a support plate 17 that supports the lower surface of the end of the beam member 14. Further, the connecting surface 15 of each of these beam support members 5 has three bolt holes 18 at the upper end communicating with the three bolt holes 8 at the upper end of the cap member 2, and two bolt holes 19 at the lower end. bolt holes 20, which communicate with the beam material 14 in the side plates 16 and the support plate 17, respectively.

The connecting surface 15 of the beam support material 5a, which matches the shape of the beam material 14, is brought into contact with the outer peripheral surface 6 of the cap material 2 to be joined. Bolts 22 are screwed and tightened through the three bolt holes 18 at the upper end of the connecting surface 15 through the bolt holes 8 in the outer circumferential surface 6 of the cap material 2 into the female threaded bolt holes 12 of the inner internal connecting material, and the beam receiving material is secured. 5 is connected to the outer peripheral surface 6 of the cap material. Another beam support member 5b connected to another outer circumferential surface 6 of the cap member 2 is also connected in the same manner as described above.

After the beam supports 5a and 5b are connected to the cap material 2, the ends of the beam members 14 are placed between the support plates 17 and the side plates 16 of the beam supports 5a and 5b, and the side plates 16
A bolt 23 passing through the beam material 14 is installed between them to connect the beam material 14 and the beam support material 5. On the other hand, the column 1 and the cap material 2 are connected to each other by fitting a bolt 24 passing through the column 1 into a bolt hole 9 provided at the lower end of the cap material 2.

The above connection structure is an example in which the beam members 14 are connected to two opposing outer circumferential surfaces 6 of the column 1, but the beam support members 5 can be similarly attached to two other opposing outer circumferential surfaces 6 of the column. It is also possible to connect four beams around the pillar 1.

Furthermore, the connection structure shown in FIG. 6 is an example in which two pillars 1 are joined in the vertical direction, and in this case, two cap members 2 are arranged so that the top plate 3 is in contact with each other, The female threaded bolt holes 7 in each top plate 3 are integrally connected to each other with bolts 25, and the internal connecting member 4 is inserted into the upper cap member 2.

As described above, in the joint structure of the present invention, the cap material 2 and the internal connection material 4 are all standardized to have the same shape, except for preparing ones with different diameters corresponding to pillars of different thickness. Only the beam supporting material 5 to be joined to the outer peripheral surface 6 of the cap material 2 is prepared as a member with a different shape corresponding to the size and shape of the beam material and girder material, as shown in Fig. 3. By setting it in place, it is possible to appropriately correspond to all types of Shiguchi structures.

Therefore, in the joint structure of the present invention, the member configuration includes the cap material 2, the internal connecting material 4, and the beam support material 5.
These parts only need to be prepared separately, and these parts can be transported to the site without being assembled in advance. Unlike a joint structure in which the receiving member is integrally protruded in advance, there is no need to manufacture in advance many types of joint members with different sizes and shapes depending on the structure of the joint part, and the standard of the member can be adjusted. It has the advantage of being simple and unified, allowing for rational storage, shipping, and transportation of parts within a warehouse, and significantly reducing manufacturing costs.
