DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure of a mating column used for a structure.

[0002]

2. Description of the Related Art In a joint portion of a pillar, a sufficient force must be transmitted between the upper and lower pillars. For this reason, a conventional integrated structure pillar has manufacturing accuracy, inspection, and on-site assembly in a factory. Great care has been taken.

[0003]

However, in order to further simplify the on-site work, there is a conventional pillar system in which a structural unit including a pillar is manufactured in a factory and each unit is assembled on-site. It is important to integrate the columns against the shearing force more than the column of the integral structure.

SUMMARY OF THE INVENTION The present invention has been made to solve this problem, and an object of the present invention is to provide a joint portion structure of a mating column in which integration with respect to a shearing force is achieved in the mating column and which is easy to assemble. .

[0005]

The joint structure according to the present invention comprises:
In the joint part of the upper and lower mating columns consisting of multiple column materials,
A fixing plate fixed to the joint end face of each column material is provided, and a connecting plate that straddles each fixing plate is disposed between the fixing plates of the upper and lower mating columns, and each fixing plate and the connecting plate are bolted. Is what you do. In addition, in the joint portion of the upper and lower mating columns composed of a plurality of column materials, each column between the opposing surfaces of the column materials at the joint end of the upper mating column and the opposing surface of the column material at the joint end of the lower mating column. A connecting plate extending over the members is arranged, and each column member and the connecting plate are bolted together. In addition, in the joint portion of the upper and lower mating pillars composed of a plurality of pillars, a fixing plate fixed to the joint end side surface of each pillar is provided, and a connecting plate that straddles each fixing plate of the upper and lower mating pillars is arranged. ,
Each fixing plate and the connection plate are bolted. Further, in the joint portion of the upper and lower mating columns composed of a plurality of column materials, a fixing plate fixed to each of the facing surfaces of the column materials at the joint end of the upper mating column and the column material at the joint end of the lower mating column With a fixing plate fixed to each of the opposing surfaces of, the connecting plate straddling the fixing plate of the upper mating post and the fixing plate of the lower mating post,
Each fixing plate and the connection plate are bolted.

[0006]

According to the present invention, the members forming the upper and lower mating columns are integrated by the plate, so that the shearing force of the mating columns is improved and the upper and lower mating columns are joined by bolt fixing the plate. The construction can be simplified simply by doing.

[0007]

FIG. 1 is a side view of a joint of a mating column showing an embodiment of the present invention. 1-4 are each pillar members, 1 and 2
Are the upper mating columns, and 3 and 4 are the lower mating columns. Plates 1a to 4a are previously welded to the joint end surfaces of the column members 1 to 4 (the welded plates are referred to as fixed plates). And, between the upper and lower fixing plates 1a to 4a, the left and right column members 1 and 2 and 3 and 4
A plate 5 (referred to as a connecting plate) is provided, which is fixed with bolts 6 integrally with the upper and lower fixing plates 1a to 4a. According to this embodiment, the on-site joining operation simply involves fastening the bolt 6 with the connecting plate 5 interposed between the upper and lower fixing plates 1a to 4a.

FIG. 2 is a side view of a joint portion of a mating column showing another embodiment of the present invention, and FIG. 3 is a sectional view taken along line AA of FIG.
A single plate 7 (this plate is referred to as a connecting plate) that is in close contact between the upper column members 1 and 2 and between the lower column members 3 and 4 is disposed, and is disposed on the left and right column members. 1,
2 and 3 and 4 are integrally fixed with bolts 8. According to this embodiment, the on-site joining operation simply involves attaching the column members 1, 2, 3 and 4 around the connection plate 7 and tightening the bolts 8.

FIG. 4 is a side view of a joint portion of a mating column showing another embodiment of the present invention, and FIG. 5 is a sectional view taken along line BB of FIG.
The column members 1 to 4 have plates 1b to 4b on both sides in advance.
Are welded (the welded plate is referred to as a fixed plate). Then, a plate 9 (hereinafter, referred to as a connecting plate) which straddles the upper and lower pillar members 1 to 4 is brought into close contact with the fixing plates 1b to 4b, and the fixing plates 1b to 4b and the connecting plate 9 are fixed with bolts 10. doing. According to this embodiment, the on-site joining operation only requires fastening the connecting plate 9 to the fixing plates 1b to 4b with the bolts 10.

FIG. 6 is a side view of a joint portion of a mating column showing another embodiment of the present invention, and FIG. 7 is a sectional view taken along the line CC of FIG.
Plates 1c to 4c protruding from both ends of this mating surface are previously welded to the column mating surfaces of the column members 1 to 4 (the welded plates will be referred to as fixed plates). And fixed plates 1c and 3 of the upper and lower mating columns
The fixed plates 1c to 4c and the connecting plate 12 are fixed with bolts 13 by bringing the plate 12 (this plate is referred to as a connecting plate) in close contact with each of the connecting plates c and 2c and 4c. According to this embodiment, the joining work on site is performed by connecting the connecting plate 12 to the fixing plates 1c to 4c.
Only the bolt 13 is tightened to c.

Note that box steel, channel steel, lip channel steel, and the like can be used for the column members 1 to 4.

[0012]

According to the joint structure of the mating column of the present invention, the members constituting the upper and lower mating columns are integrated by the plate (connecting plate), so that the shearing force of the mating column is improved. At the same time, the joining of the upper and lower mating columns can be simplified by simply fixing the plate with bolts.
