Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 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 the column. A joint ring consisting of a gusset integrally formed on the outer four sides of the ring body is fitted around the column of the beam joint portion of the steel pipe column, and the joint ring is filled between the support member around the column and the column and the joint. There is described a construction method in which the steel tube column and the steel frame beam are integrally bonded by fixing with.

[0003]

In the construction method employing such a joining ring, the steel pipe columns of the height of the multi-storey floor are used for the H of each floor.
This is convenient when joining shaped steel beams, but there is a problem that it is difficult to adopt when performing construction of beams while adding steel tube columns, or when joining other column bodies to the upper end of the steel tube columns.

The present invention was conceived in order to solve the above-mentioned conventional problems, and an object thereof is to simultaneously join a steel pipe column, an upper floor column and an H-shaped steel beam at a joint by a joining ring. It is to provide a ring panel construction method that can be done.

[0005]

The features of the present invention according to the above object are to join a concrete-filled steel tubular column and an H-shaped steel beam through a joining ring made of a steel pipe fitted around the steel tubular column. A support member is provided around the upper end of the steel pipe column, and the joining ring is placed on the support member to surround the column end from above with the joining ring, and at the end of the column, the pillar of the upper floor is provided. The steel pipe column is integrally joined to the column body of the upper floor and the H-shaped steel beam by a filling material such as mortar filled in the building and joining ring.

[0006]

[Operation] In the above construction method, the upper and lower columns and the H-shaped steel beam are integrally joined at the joint portion by the joining ring and the filling material such as mortar filled inside the joining ring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 in the drawing is a rectangular steel pipe column having a height of one floor, and concrete 2 is filled inside except for the upper end. Around the upper end of the steel pipe column 1, a supporting member 4 having a required width on which a joining ring 3 made of steel pipe is placed is horizontally attached by welding.

The joining ring 3 has a ring body 5 made of a steel pipe having a diameter larger than the width of the column and having an inner diameter of the column corner, and an outer stiffener integrally formed by fillet-welding on the upper and lower sides of the ring body 5. It consists of rings 6 and 6.

The outer stiffener ring 6 is provided with upper and lower flanges 7, 7 on four sides and a web 8 between the flanges 7, 7, and its cross-sectional shape and dimensions are the same as those of an H-shaped steel beam which is a girder. ing.

The joining ring 3 is fitted and inserted around the upper end of the support pipe 4 from the upper end of the post after the steel pipe post 1 has been built.
Placed above the support member 4, thereby surrounding the support member 4,
A ring main body 5 is formed in the upper end of the pillar to form a socket for the pillar body on the upper floor. Further, after mounting, the joining ring 3 is rotated to determine the positions of the upper and lower flanges 7, 7.

After this positioning, the H-shaped steel 10 to be the pillar body of the upper floor is built in the upper end 9 of the pillar together with the surrounding bar arrangement 11. After being built, the space 11 inside the upper end 11 of the column and the space 12 inside the joining ring is filled with a filler 13 such as concrete or non-shrink mortar while maintaining the vertical, and the steel pipe column 1 and the H-shaped steel 10 are integrally joined.

The joining of the steel pipe column 1 and the H-shaped steel beam 14 is performed after the positioning of the joining ring 3 is completed and when the H-shaped steel beam 10 is joined.
There is a case where the above-mentioned construction is performed after the joining ring 3 is fixed by the filling material in advance.

In any of the cases, the H-shaped steel beam 14 is suspended between the outer stiffener rings 6 which are correctly set on the opposing steel pipe columns, and the web joint plate 1
5 is used to joint both to the webs 8,16. When the H-shaped steel beam 14 is joined first, the steel tube column 1, the H-shaped steel beam 14 and the H-shaped steel 10 are integrated after 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 shaped steel beams 14 are joined, as shown in FIG. 5, the joining ring 3 may be directly fixed to the end of the H shaped steel beams 14 by welding. In this case, the H shaped steel beams 14 are suspended. The joint ring 3 is fitted and inserted into the pair of steel pipe columns facing each other with a gap, and then fixed by the filler 13.

Further, when the pillar on the upper floor has the same shape as the steel pipe pillar 1, a short-axis H-shaped steel is used as an inner joint, and like the H-shaped steel 10 of the above-mentioned pillar, together with the reinforcing bar 11 in the upper end 9 of the pillar. The space inside and around the steel pipe column 1a is built up and covered with the steel pipe column 1a on the upper floor so that the lower end abuts on the upper end of the steel pipe column 1 on the lower floor, and then keeps the vertical position. It is sufficient to fill the above with the filling 13.

Although the embodiment describes a square 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 to be larger than the outer diameter of the steel pipe column. In addition, although H-shaped steel is used as the pillars on the upper floor, the pillars include those in which a pair of C-shaped steels are combined back-to-back, cross-shaped steels, cross-shaped steels having strip steels at each end, and the like. The present invention does not particularly limit the column to the H-section steel, since the section steel that is normally used can be adopted.

[0017]

As described above, according to the present invention, the supporting member is provided around the upper end portion of the steel pipe column, the joining ring is placed on the supporting member, and the upper portion from the column end portion is surrounded by the joining ring. At the same time, the pillars of the upper floor are built at the ends of the pillars, the joint ring is filled with mortar, and the steel pipe pillars and the pillars are integrally joined. Can be joined. Further, since the upper and lower pillars and the H-shaped steel beam can be joined at the same position and at the same time, the process can be simplified and the labor can be saved.

Further, when a joining ring having an outer stiffener ring is adopted, the steel pipe column can be doubly restrained by the joining ring serving as the outer pipe and the outer stiffener ring, so that the joint is robust even in the joint. In addition, the H-shaped steel beam directly attached to the joining ring has the advantage that the fitting size is small, and the joint part can be easily joined on-site, so it can be applied to the laminated construction method. Have.
