Abstract

PROBLEM TO BE SOLVED: To facilitate connection by fixing a side plate to the apex outside of the cross section of a steel pipe column in the bisector direction of the apex when a structural material is connected to the steel pipe column made of an angular steel pipe via the side plate. SOLUTION: A side plate 16 for connecting a square steel pipe 11 and a structural material 21 is fitted to the apex outside of the cross section of the square steel pipe 11 in the bisector direction, and the force applied to the side plate 16 is shared by side face sections 11a, 11b. A base plate and a top plate are fixed to the upper end face and lower end face of the square steel pipe 11 so that the side sections of the base plate and top plate are fixed to the square steel pipe 11 to form 45 deg. against the side face sections 11a-11d of the square steel pipe 11. A steel pipe column can thus be joined to the structural material 21 in accurate positional relation without its side face sections bent.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure between a prism and a structural member for joining a structural member to a steel pipe column of a building via a side plate.

[0002]

2. Description of the Related Art In recent years, square steel pipes have been frequently used for pillars of a two- or three-story house, and this type of square steel pipe is joined to a square steel pipe and a foundation or another square steel pipe. The base plate for joining, the top plate for joining the square steel pipe to the roof or other square steel pipe, the side plate for joining the square steel pipe to the structural members such as the horizontal members and braces are welded. Fixed.

For example, as shown in FIG. 10, a base plate 2 is fixed to a lower end surface of a square steel pipe 1 by a welding material 3.
A top plate 4 is fixed to an upper end surface of the square steel pipe 1 by a welding material 5. A side plate 6 having a bolt hole 6a is provided on the upper side surface of the square steel pipe 1 outward. As shown in FIG. 11, the side plate 6 is fixed to the center of the side surface 1a of the square steel pipe 1 by a welding material 7.

[0004]

However, in the above-described conventional example, the side plate 6 is provided at the left and right center of the side portion 1a of the square steel pipe 1, so that when the structural material is joined to the side plate 6, In addition, there is a problem that the side surface portion 1a bends as indicated by a chain line, and the structural material is shifted from a predetermined position.

An object of the present invention is to solve the above-mentioned problems,
It is an object of the present invention to provide a connection structure between a prism and a structural material capable of joining a steel pipe column and a structural material in an accurate positional relationship.

[0006]

According to the present invention, there is provided a connection structure for connecting a prism and a structural material to achieve the above object by connecting a steel pipe made of a square steel pipe to a steel pipe through a side plate fixed to the steel pipe. In joining the members, the side plate is fixed to the outside of the top of the cross section of the steel pipe column in the direction of the bisector of the top.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the embodiments shown in FIGS.

FIG. 1 is a front view of an embodiment, and FIG. 2 is a cross-sectional view. The steel pipe column is a square steel pipe 11 having a square cross section and having side portions 11a to 11d. A square base plate 12 for joining the square steel pipe 11 to a foundation of a building (not shown) or another square steel pipe 11 is fixed to a lower end surface of the square steel pipe 11 by a welding material 13. Further, a square top plate 14 for joining the square steel pipe 11 to the roof of a building or another square steel pipe 11 is fixed to an upper end surface of the square steel pipe 11 by a welding material 15. And
Above the square steel pipe 11, a rectangular side plate 16 for joining the square steel pipe 11 and structural materials such as lateral members, braces, and auxiliary members, which will be described later, is fixed by a welding material 17, for example.

Here, the base plate 12 and the top plate 14 are formed such that their sides are the side portions 11 of the square steel pipe 11.
It is attached so as to form 45 ° with respect to a to 11d. Further, the side plate 16 is a bisector direction of an angle formed by the side surface portion 11a and the side surface portion 11b from the intersection of the side surface portion 11a and the side surface portion 11b of the rectangular steel pipe 11, that is, the side surface portion 1
1a or the side surface portion 11b is oriented in a direction forming θ = 135 °. The plates 12, 14, and 16 have bolt holes 12a, 14a, and 16a (the bolt holes 12a are not shown).

Such a side plate 16 can be provided near the base plate 12, near the top plate 14, or at an intermediate portion between the base plate 12 and the top plate 14. Then, the lateral member 21 is fixed to the side plate 16 with a bolt 22 as shown in FIG. 3, or a brace 23 is attached to a bolt 24 as shown in FIG.
, Or the auxiliary member 25 can be fixed by bolts 26 as shown in FIG.

As described above, in the embodiment, the side plate 16 for joining the rectangular steel pipe 11 and the structural members 21, 23, 25 is provided on the outer side of the top of the cross section of the rectangular steel pipe 11 in a bisector direction. , The force applied to the side plate 16 can be shared by both the side surface 11a and the side surface 11b. Therefore, the side portion 11 of the square steel pipe 11
The rectangular steel pipe 11 and the structural material can be joined in an accurate positional relationship without the a and the side portion 11b being bent.

Further, since the base plate 12 and the top plate 14 are fixed to the square steel pipe 11 so that the sides of the base steel plate 11 and the side parts 11a to 11d of the square steel pipe 11 make an angle of 45 °, the base plate 12 and the top plate 14 If the attachment is performed based on the bolt holes 12a of the base plate 12 as in the past,
Since the side plate 16 protrudes in a direction parallel to the sides of the base plate 12, there is no problem in fixing the structural material to the side plate 16.

In the above embodiment, the side plate 16 is used.
Is provided only at the intersection of the side surface 11a and the side surface 11b of the square steel pipe 11, but also provided at the intersection of the side surface 11c and the side surface 11d as shown in FIG. 6, and as shown in FIG. The horizontal members 21 can also be joined to the side plates 16 by bolts 22, respectively. Also, the side plate 16
Can be added to the intersection of the side surface portion 11b and the side surface portion 11c as shown in FIG. 8, or can be added to the intersection of the side surface portion 11d and the side surface portion 11a as shown in FIG.

Furthermore, although the cross-sectional shape of the square steel pipe 11 is square, there is no problem even if it is rectangular. And although the side plate 16 was fixed to the square steel pipe 11 by the welding material 17, it may be fixed by a bolt.

[0015]

As described above, in the connection structure between the prism and the structural material according to the present invention, the side plate for joining the steel tube and the structural material is provided on the outer side of the top of the cross section of the steel tube with 2 grades. Since it is fixed in the direction of the dividing line, both side portions of the steel pipe column share the force applied to the side plate. For this reason, the side portion of the steel pipe column does not bend, and it becomes possible to join the steel pipe column and the structural material in an accurate positional relationship.
