[Detailed Description of the Invention] "Industrial Application Field" The present invention is applied to a rectangular space portion surrounded by columns and beams of a multi-storey steel frame building, which requires an earthquake resistant element, when it is installed and used. The present invention relates to a suitable steel frame brace frame structure.

"Prior art" For steel braces that mainly function as reinforcing members in steel-framed buildings, both tensile braces using reinforcing bars or chevron steel and tension and compression using H-shaped steel and square steel pipe are effective. There are braces that have worked, and there are various types of braces such as X-type and K-type.

By the way, as a function required for such a steel brace, not only high rigidity for exerting an original reinforcing function but also buckling due to an axial force or a bending moment generated based on an external force such as wind and rain or an earthquake is required. Not enough toughness is also required. In particular, high-rise steel-framed buildings are generally designed as so-called flexible structures that can mitigate the effects on seismic input, etc. Therefore, in such flexible-structured buildings, the toughness of steel braces is In order to have an important seismic function, it is necessary to take measures to improve the toughness of the steel braces themselves. Further, in recent years, in order to suppress the rolling of the entire building which is likely to occur due to the flexible structure, measures have been taken to provide a vibration damping device or the like separately from the brace.

[Problems to be solved by the device] However, in the case of the former tensile brace among the above-mentioned conventional braces, the restoring force characteristics after member yielding due to repeated loads such as earthquakes are slip-like, so in terms of rigidity. Not preferable. On the other hand, the latter brace also buckles when the slenderness ratio is large, and the hysteresis curve thereafter has a negative gradient, so toughness cannot be expected. Therefore, for example, in the design of skyscrapers, conventionally, the slenderness ratio λ is set to 30 or less to prevent a decrease in proof stress due to buckling. Not only becomes large and uneconomical, but also causes problems such as structural balance and floor plan problems.
Therefore, there is a problem that it is difficult to sufficiently improve the toughness. Further, when the mechanical vibration damping device is provided separately from the brace, it is not very effective in spite of the large size and the large cost, which is a problem in terms of cost efficiency.

Therefore, in the present invention, the brace is provided with both the rigidity adjusting function and the toughness adjusting function for making buckling less likely to occur, and moreover, the shaking based on the external force of the building is effectively performed by the relatively inexpensive means which is easy to manufacture. Further, the present invention intends to provide a frame structure of a steel frame brace that also has a damping function that can be suppressed early.

In addition, each brace material has a through hole that penetrates each brace material, and wraps the inside of the through hole by penetrating the crossing portions of the brace materials and the vicinity of the crossing portion.
Since each brace member is constrained by a structural member made of concrete or fiber reinforced resin having a rigidity capable of restraining, the rigidity of the brace member is substantially improved, and the brace member is relatively displaceable. Therefore, the toughness is sufficiently secured, and as a result, a steel frame brace that is resistant to buckling is formed.

The structural member 4 is formed in a rectangular panel shape that is similar to the framed quadrilateral as a whole, centering on the intersection of the brace members 3 and 3 and extending further from the intersection. . This rectangular panel-shaped structural member 4
Is light and has high compressive strength and is formed of lightweight concrete having rigidity capable of restraining each of the brace members, and has a through hole for penetrating each of the brace members 3, 3 in a diagonal direction of a rectangle. A structure is provided in which a crossing portion between the respective brace members 3 and 3 and the vicinity of the crossing portion are penetrated into the through hole and wrapped in the inside thereof.

In the case of a steel frame brace having such a structure, it is of course possible to build it up at the construction site including the structural member 4 part made of lightweight concrete, but from the viewpoint of workability, it is desirable to make it a prefabricated structure. As an example of manufacturing when prefabricating, the viscous body used for the resistor 5 is formed on the surface of the brace material 3, 3 by a method suitable for the properties and workability of the viscous body, for example, a method such as sticking or assembling. The viscous material layer is formed in a necessary range and thickness with respect to each of them, and then, in a state where both the brace members 3 and 3 are arranged back to back in an X-shape, the viscous material layer portion that becomes the resistor 5 is formed. The lightweight concrete can be easily manufactured by adopting a method of molding the lightweight concrete into a shape corresponding to the structural member 4 in a form of wrapping the whole and hardening it.

In the steel brace having such a structure, when a horizontal force is exerted on the basis of an external force such as an earthquake, the brace members 3 and 3 and the brace members 3 and 3 and the structural member 4 are relatively opposed to each other. Although displacement occurs, when the relative displacement occurs, the resistor 5 existing between them exerts an action of suppressing the relative displacement, and as a result, the steel braces are prevented from swaying or vibrating. The function of suppressing or attenuating early occurs.

In addition, the structural member 4 connects the brace members 3 and 3 via the resistor 5.
Since it has a structure in which the crossing portion and the vicinity of the crossing portion are wrapped and restrained, the rigidity of the brace members 3 and 3 is improved, and buckling can be prevented accordingly. In other words, the slenderness ratio of the brace material, which is a factor that influences the relationship between the rigidity and the buckling of the brace materials 3 and 3, is substantially reduced by the presence of the structural member 4, and as a result, even the brace material having the same cross section is obtained. The smaller the slenderness ratio is, the higher the rigidity is, and the structure is less likely to buckle.

On the other hand, considering the toughness of the brace members 3 and 3, when the brace members 3 and 3 are not rigidly connected to each other, they are constrained by the structural member 4 via the viscous resistor 5. Since both of the brace members 3 and 3 have a structure capable of relative displacement, sufficient toughness is ensured. As can be understood from this, the structural member 4 and the resistor 5 are
Based on the unique combination structure with brace materials 3 and 3,
In addition to the function of effectively damping the shaking of the building, it also exerts a function of adjusting or improving rigidity and toughness that makes it difficult for the steel braces themselves to buckle.

Further, according to the embodiment, since the structural member 4 is located around the intersection of the X-shaped brace, the brace member 3,
Even if the three are relatively displaced, they will eventually return to their original positions, and no positional deviation will occur. Further, in terms of manufacturing, since it has a simple structure in which it is combined with a brace material, not only new manufacturing is easy, but also existing steel frame braces can be easily applied.

FIG. 4 shows another embodiment suitable for using rubber asphalt for the viscous body which becomes the resistor 5 when the steel brace is prefabricated and manufactured. In this embodiment, the brace material used is A viscous body 7 having a convex cross-section having a through hole 7a through which 3 can be inserted is manufactured, and the viscous body layer is easily formed on the surface of the brace material by covering each of the brace materials 3 and 3. It was made possible. Of course, in this case as well, the two brace members 3 and 3 with the viscous body 7 are arranged back to back in an X shape, and then the structural member 4 is molded with lightweight concrete as in the previous embodiment. It is similar to the case.

Further, as the resistor 5, for example, as shown in FIG. 5, an X-shaped viscous body 8 may be used which has a shape in which the above-mentioned tube-shaped viscous bodies are integrally formed so that they are back to back. By doing so, it is possible to further improve the manufacturability. When the asphalt compound is used for the viscous body serving as the resistor, it may be preliminarily attached to the surface of each brace material so as to have a required layer thickness.

Needless to say. Further, the structural member 4 can also be configured by using ordinary concrete, GRC (fiber reinforced concrete), FRP (fiber reinforced plastic) or the like in addition to lightweight concrete.
