Abstract

PURPOSE: To simplify structure and construction while being excellent from the viewpoint of design and function in use and enable even laymen to easily perform field construction while making construction control desirable. CONSTITUTION: H-shape steel beams 2 are jointed through to H-shape steel incorporating main columns 1 by high tension bolts 5 to form a framed skeleton, and the vertical brace 3 of H-shape steel is provided at the center between the main columns 1, 1. At this time, the vertical brace 3 is erected so that the flange faces of the main columns 1 and the flange face of the vertical brace 3 are right-angled to each other. The vertical brace 3 can also be independent of every through column or every floor.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel frame structure for a structure in which an H-shaped steel beam is joined to a through H-shaped steel column with high-strength bolts to form a frame, and in particular, instead of a conventional brace. The present invention relates to a steel frame structure using vertical braces using H-section steel as studs.

[0002]

2. Description of the Related Art A conventional steel frame structure is shown in FIG.
As shown in FIG. 5, the beam (2) is attached to the through H-shaped steel column (1) by welding, and the braces (3 ′) are welded and bolted between the H-shaped steel columns (1) and (1). It was a structure to attach.
The H-shaped steel column is strong against the force applied to the flange surface, but weak against the force applied at right angles to the flange surface, and is generally dealt with by providing braces (3 ') in this direction. Was there.

[0003]

However, since the brace (3 ') of the steel frame structure is an oblique member, dimensional accuracy has been required very severely in manufacturing and mounting. Further, when the window is provided, the brace (3 ′) becomes an obstacle as shown by the imaginary line in FIG. 5, and the window is not designed to come to that part, or the window position is determined in advance and the brace (3 Although the method of deciding the position of ') is adopted later, it cannot be said that it is necessarily excellent in terms of design and function of use because it is restricted by design. Further, since the H-shaped steel column (1), the H-shaped steel beam (2), and the braces (3 ') are often joined by welding, it is necessary to prepare a large number of welders and to perform pretreatment and post-welding. There is a problem in that treatment and inspection are required, the construction period depends on the number of welders, and it is difficult to always secure a large number of welders.

It is an object of the present invention to provide a steel frame structure structure using vertical braces, which is improved in design and use functions and has a simple structure and can be constructed easily.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, that is, an H-shaped steel beam is joined to a through main column of an H-shaped steel by a high-strength bolt to construct a frame structure. And vertical braces of H-section steel in the center between the main columns (studs)
Is provided. At this time, the vertical braces are erected at the center between the main columns and the flange surface of the vertical brace is shifted at right angles to the flange surface of the main columns. The vertical braces may be independent through columns or floors.

[0006]

Next, the construction of the steel frame structure of the present invention will be described. First, build the main pillar (1). At this time, the main pillar (1) is set by the inventor of the present application filed on Dec. 27, 1994 by the patent application “column base anchor bolt fixing method” so that the anchor bolts can be accurately dimensioned. By doing so, it becomes an exposed type fixed column pedestal to reduce the number of steel members.
Next, based on the calculation sheet, a vertical bracing (3) of H-section steel is built through between the main columns (1) and (1) or independent for each floor.
At this time, the exposed pin joint structure is used, and the flange surface of the H-section steel is offset from the main pillar (1) at a right angle. This is because the vertical braces (3) serve to reinforce the main columns (1) in the weak axis direction. The weak axis direction in the present invention means a direction perpendicular to the flange surface of the H-section steel. After construction, the beam (2) is bolted to the H-shaped steel main column (1) or vertical braces (3) using the joining hardware such as split T (4) and high strength bolts (5) to form the frame structure. Yes (Fig. 1
~ See Figure 3). At this time, the welding work is significantly reduced and the joint strength confirmation is omitted by tightening the torquer bolt. In addition, we established a simple construction method that does not use braces (3 '), and use vertical braces (3) instead of braces (3').
Is an H-shaped steel erected only as a stud, without making any other structural changes, and the structural calculation can be performed with the conventional span, and standard members can be used as they are. Further, in the conventional brace (3 ′), the position of the window (6) is restricted as shown by the imaginary line in FIG. 5, but the window (6) is not restricted as shown by the imaginary line in FIGS. 2 and 3. Can be provided.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. (1) is a main column of H-section steel, and the main column (1) is used as a through column. (2) is an H-shaped steel beam, and (3) is a vertical bracing of the H-shaped steel erected in the center between the main columns (1) and (1). The flange surface of this vertical bracing (3) Are erected vertically offset from the flange surface of the main pillar (1). This deviation constitutes reinforcement in the weak axis direction of the main columns (1), (1). or,
The vertical braces (3) may be through studs as shown in FIG. 2 or independent studs for each floor as shown in FIG.

[0008]

The present invention having the above-mentioned constitution has the following effects.

A through main pillar (1) of H-section steel as claimed in claim 1.
The H-shaped steel beam (2) is joined to the frame with a high-strength bolt (5) to form a frame structure, and the conventional brace (3 ') is used between the main columns (1) and (1). By providing the vertical braces (3) of H-section steel in the above, the conventional diagonal member which is required to have dimensional accuracy is not required, and the structure is simple and the construction can be simplified. In addition, it is excellent in terms of design and functions used. Furthermore, by eliminating welded joints as much as possible and joining with a joint metal such as the split T (4) with a high-strength bolt (5), even on-site construction can be performed easily even by an amateur, and construction management is accurate. It will be. It should be noted that the steel frame structure of the present invention is assembled by bolt joining, the welding work is greatly reduced, and the joining strength confirmation can be omitted by tightening with the torquer bolt.

According to a second aspect of the present invention, the vertical braces (3) are provided in the weak axis direction of the main columns (1), (1) so that the flange surface of the vertical braces (3) faces the adjacent main columns (1). This eliminates the need for braces (3 ') between the main columns (1) and (1), and can eliminate the intersection.

As shown in claim 3, the structure is simple by vertically arranging through the vertical braces (3), that is, up to the second floor in the case of a two-story building and up to the third floor in the case of a three-story building. ,
It is possible to reduce H-section steel.

[0012] As the vertical braces (3) are independent for each floor as described in claim 4, the degree of freedom in design is increased.
