DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ring panel method for joining a steel pipe column filled with concrete and an H-shaped steel beam via a connection ring formed by a steel pipe inserted around the steel pipe column.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication No. Hei 5-214736 discloses a steel pipe ring body having an inner diameter larger than the outer diameter of the column and forming a required clearance between the column and a steel beam having the same sectional shape as a steel beam. A joining ring composed of gussets integrally formed on the outer sides of the ring body is fitted around the column at the beam joining portion of the steel pipe column, and the joining ring is filled with a support member around the column and a filler between the column and the joint. And a method of joining the steel pipe column and the steel beam integrally.

[0003]

In the construction method using such a joint ring, a steel pipe column having a height of a multi-story floor is provided with a H pipe of each floor.
Although it is convenient to join a steel beam, it has a problem that is difficult to adopt when the beam is constructed while adding a steel pipe column, or when another column is joined to the upper end of the steel pipe column.

The present invention has been conceived in order to solve the above-mentioned conventional problems. It is an object of the present invention to simultaneously join a steel pipe column, an upper story column, and an H-shaped steel beam at a joint by a joining ring. An object of the present invention is to provide a ring panel method that can be accomplished.

[0005]

SUMMARY OF THE INVENTION The present invention according to the present invention is directed to a method of joining a steel pipe column filled with concrete and an H-shaped steel beam via a joint ring formed by a steel pipe inserted around a steel pipe column. A supporting member is provided around the upper end of the column, and the joining ring is placed on the supporting member and the upper side from the column upper end is surrounded by the joining ring,
The H-section steel, which will be the upper floor column, is built in the upper end of the column together with the surrounding reinforcing bars, and protrudes above the joint ring. The filler such as mortar is filled in the upper end of the column and the space inside the joint ring. After filling, the steel pipe column, the column body on the upper floor and the H-shaped steel beam are integrally joined.

[0006]

In the above construction method, the upper and lower columns and the H-shaped steel beam are connected to the joint ring and the column built in the column upper end, and the filler such as mortar filled in the column upper end and the space inside the joint ring. As a result, the joint is integrally formed at the connection portion, whereby the stress transmission between the upper and lower portions of the steel pipe column is achieved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawing, reference numeral 1 denotes a square steel pipe column having a height of one floor, and concrete 2 is filled inside except for an upper end portion. A support member 4 having a required width on which a joining ring 3 made of a steel pipe is placed is mounted horizontally around the upper end of the steel pipe column 1 by welding.

The joining ring 3 is made of a steel pipe ring body 5 having a diameter larger than the width of the pillar and having an inside diameter in which the corner of the pillar can be accommodated, and an outer stiffener integrally provided on the outside of the ring body 5 by fillet welding. It consists of rings 6,6.

The outer stiffener ring 6 has upper and lower flanges 7, 7 on all sides and a web 8 between the flanges 7, 7, and has the same cross-sectional shape and dimensions as an H-shaped steel beam serving as a large beam. ing.

After the steel pipe column 1 has been completely installed, the joining ring 3 is inserted from the upper end of the column to the periphery of the upper end portion to insert the support member 4.
, Thereby surrounding above the support member 4,
At the upper end of the column, a socket for the upper floor column by the ring body 5 is formed. After the mounting, the position of the upper and lower flanges 7 is determined by rotating the joining ring 3.

After this positioning, an H-shaped steel 10 which is to be a pillar on the upper floor is erected together with the surrounding reinforcing bars 11 in the inside 9 of the pillar upper end, and protrudes from the joining ring. After the erection, the filler 1 such as concrete or non-shrink mortar is placed vertically 11 in the upper end of the column and in the space 12 inside the joint ring.
3 and the steel pipe column 1 and the H-shaped steel 10 are integrally joined. This makes it possible to transmit the stress between the upper and lower portions of the steel pipe column.

The joint between the steel pipe column 1 and the H-shaped steel beam 14 is performed after the positioning of the joint ring 3 is completed.
In some cases, the mounting is performed after the joining ring 3 is fixed with the filler in advance.

In either case, the H-shaped steel beam 14 is suspended between the outer stiffener rings 6 set correctly on the opposed steel pipe columns, and the web joint plate 1
5, both of which are joined to the webs 8,16. When the joining of the H-shaped steel beam 14 precedes, the steel pipe column 1 is integrated with the H-shaped steel beam 14 and the H-shaped steel 10 via the joining ring 3 by the filler 13.

In the above embodiment, the joining ring 3 has the outer stiffener ring 6, and the outer stiffener ring 6 has H
Although the section steel beam 14 is joined, the joining ring 3 may be directly fixed to the end of the section H beam 14 by welding as shown in FIG. 5. In this case, the suspension of the section H beam 14 is used. With this, the joining ring 3 is inserted into the pair of steel pipe columns facing each other, and then fixed by the filler 13.

When the column on the upper floor has the same shape as the steel tube column 1, the H-shaped steel having the short axis is used as the inner joint, and the reinforcing member 11 is provided together with the reinforcing member 11 in the upper end 9 of the column, similarly to the H-shaped steel 10 of the column. It is built, and furthermore, as shown by a dashed line, the upper steel pipe column 1a is covered, and the lower end is brought into contact with the upper end of the lower steel tube column 1, and thereafter the space inside and around the steel pipe column 1a is kept vertical. May be filled with the filler 13.

Although the embodiment describes a rectangular steel pipe column, the steel pipe column may have a circular cross section. In this case, a ring is formed so that a filling clearance is generated between the joining ring and the steel pipe column. It is necessary to form the inner diameter of the main body larger than the outer diameter of the steel pipe column. In addition, although the H-shaped steel is used as the column of the upper floor, the column is a combination of a pair of C-shaped steels back to back, a cross-shaped steel, a cross-shaped steel having a band steel at each side end, and the like. The present invention does not particularly limit the columnar body to the H-shaped steel, since a commonly used steel can be employed.

[0017]

As described above, according to the present invention, a support member is provided around the upper end portion of a steel pipe column, and the above-mentioned joining ring is placed on the supporting member, and the upper portion from the column end is surrounded by the joining ring. At the same time, the H-section steel, which will be the upper floor column, is built inside the column upper end together with the surrounding reinforcement, and protrudes from the joint ring.
Filling the space inside the upper end of the column and the inside of the joining ring with mortar or the like, and joining the steel pipe column and the upper floor column and the H-shaped steel beam integrally, Columns can be joined. Further, since the joining of the upper and lower columns and the H-shaped steel beam can be performed at the same position and at the same time, the process can be simplified and the labor can be saved.

Further, when a joint ring having an outer stiffener ring is employed, the steel pipe column can be double-constrained by the joint ring serving as the outer tube and the outer stiffener ring. In addition, when the H-shaped steel beam is directly attached to the joint ring, it also has the advantage that the fitting size can be small, and the joint can be easily joined on site so that it can be applied to the lamination method. Having.
