Description

[Detailed description of the invention] Industrial application field This invention relates to the structure of a steel column made of H-section steel.

2. Description of the Related Art In a building having a steel structure using H-shaped steel columns, a joining plate is previously welded to an end of the H-shaped steel, and the joining plate and a horizontal member such as a beam are joined via bolts. Is done. FIG. 5 shows the joining structure, in which an H-section steel column (1) is joined so that its web (2) is in the same direction as the beam (3). ), The joint plate (5) is welded in advance across the flanges (4) and (4), and the bolt plate (6) formed in the joint plate (5) is used to form the joint plate (5). The beam (3) is attached to the upper surface of the upper flange (7) by bolts (8). (9) is a floor panel, and the floor panel (9)
When the horizontal mounting plate (10) protruding at the end of the column (1) is fixed on the beam (7), the mounting plate (10) is connected to the joint plate ( It is installed on the upper surface of 5) and is fixed with bolts.

On the other hand, FIG. 5 shows a column used for a portion requiring a large proof stress. In this case, a large H-shaped steel having a web (2) width approximately twice that of the column shown in FIG. The longitudinal ribs (11) and (11) are welded to the center of the web on both sides, and a large joining plate (5) is welded to the end face. Then, in the same building, the structure shown in FIG. 4 and the structure shown in FIG. 5 are selectively used depending on the required strength.

Problems to be Solved by the Invention In the above-mentioned conventional structure, an H-section steel having a size about twice as large as a normal size is used for a portion having a large proof strength. Two types of H-beams are required, and there is a disadvantage that the number of members increases and the cost increases.

Further, in this type of steel frame structure, design standards stipulate that, in accordance with the cross-sectional performance of the column itself, a load corresponding to the load applied to the joint plate (5) should be given a strength corresponding thereto. In the structure of FIG. 5, the joining plate (5)
The strength of the parts had to be increased, complicating the design and increasing the cost from this point as well. Further, in the above structure, since the mounting plate (10) of the floor panel (9) is set on the joining plate (5), the floor panel (9) has a thickness corresponding to the thickness of the joining plate (5). Will be higher. Therefore, in this conventional mounting structure, since the height of the floor panel (9) installed on the pillar (2) portion is increased, the height of each floor panel is made uniform in other portions. In this case, a spacer having the same thickness as that of the joining plate (5) must be provided, so that the number of parts increases and the operation becomes complicated.

The purpose of this invention is to eliminate the disadvantages of the conventional column shown in FIG.

Means for Solving the Problems In order to solve the above problems, in the present invention, a pair of column members made of H-shaped steel are arranged in parallel with each other so that their webs are substantially in a straight line, The same joining plate fixed to each of the column members at the end surfaces corresponding to the flanges of the members, and the first and second column members are proudly fixed to the column members corresponding to the flanges adjacent to each other. Are joined to each other.

According to the present invention, the respective pillars are connected to each other via the joining plate, and the integrated member is installed at a necessary position, and each joining plate is joined to the beam with bolts or the like. The column members are connected as described above using the same two H-shaped steel columns that require ordinary strength. Between each joining plate, a mounting plate such as a floor is fixedly disposed on the beam.

Embodiment FIG. 1 shows the pillars of the present invention.
(21) (21) is a pair of column members made of H-shaped steel,
The webs (22) and (22) are juxtaposed to each other so as to be substantially co-linear with each other, and each has a rectangular joint corresponding to the outer flanges (23) and (23) in the juxtaposition direction. Plates (24) and (24) are welded to both upper and lower ends.
Adjacent parallel inner flanges (26) (26)
At the position corresponding to the above, the same one joining plate (27) (27) is similarly welded to both upper and lower ends across both pillar members (21) (21), and the joining plate (27) (27) ), The two pillar members (21) and (21) are integrally connected. Each joint plate (24) (27) has four bolt holes (28) at each corner.

FIG. 2 and FIG. 3 show the mounting structure of the column (29) to the beam. The beam (30) is formed by arranging the H-section steel so that its flanges (31) and (31) are vertically parallel. In the figure, the connecting plates (24) and (27) at the lower end of the column (29) are shown.
On the flange (31) on the upper side, and tighten the bolts (3
It is fixed in 2). The mounting structure is the same at the upper end, and the joining plates (24) (27) at the upper end
Abuts against the lower surface of the lower flange (31) of the beam (30) and is fixed with bolts. (33) is a normal column made of one H-shaped steel, which is joined to the lower surface of the beam (30) in this figure. (34) is a floor panel made of a concrete plate, and a mounting plate (35) protruding from the end face thereof,
Between the joining plates (24) and (27), the beam is mounted on the upper surface of the upper flange (31) of the beam (30) and is fixed by bolts (36).

According to the present invention, since a pair of column members made of H-shaped steel are connected to each other to form a column having a large proof strength, it is possible to use an H-shaped steel column used at a place where the proof strength is not so necessary. There is no need to use a large H-shaped steel as in the past,
The cost can be reduced by sharing the members.
Also, with such a structure, the section modulus becomes smaller than in the case of using the above-described conventional large column member,
Accordingly, since the proof stress of the joint can be reduced, the cost can be reduced also in this regard. In addition, since each joining plate is divided, by installing a mounting plate for the floor plate between the joining plates, the same height as the floor plate at another position can be obtained. Therefore, unlike the related art, it is not necessary to provide a spacer in another portion to make the height of the floorboard uniform, and there is an effect that the number of parts is reduced and the number of working steps is reduced accordingly. Furthermore, the welding length is shorter than in the conventional case where ribs are welded in the longitudinal direction of the web, which is also economical.
