Japanese Patent Laid-Open No. 2001-220818

  The inventor of the present invention considered that there is room for improvement in the shape of the reinforcing member in the background art. The problem to be solved by the present invention is to provide a reinforcing member with improved working efficiency and strength, and to provide a steel frame structure using the reinforcing member.

  The present invention uses a steel frame as a structural member of a steel frame, and separates the pillar into a lower floor pillar and an upper floor pillar at the top and bottom of the lower floor. Columns and upper floor columns are individually connected to the beam material with bolts up and down, and a reinforcing member is applied to the side of the portion where the beam column is connected. In the steel frame structure in which materials can be combined, the reinforcing member is formed of a substantially box-shaped box that is just circumscribed from the outer surface of the rib of the beam material to the upper and lower flanges.

  Also, among steel frame components, steel is used as the beam material, and the column is divided into a lower-level column and an upper-level column at the beam material part up and down. The upper columns are individually connected to the beam with bolts up and down individually, and a reinforcing member is applied to the side of the portion where the beam columns are connected, and the beam and girder are attached to the beam with this reinforcing member. A reinforcing member for use in a steel frame structure that can be coupled to each other, characterized by comprising a substantially box-shaped box body that circumscribes just the upper and lower flanges from the outer surface of the rib of the beam material.

  Since the present invention has the above-described configuration, it is self-supporting when temporarily placed on a flange of a beam material made of steel, and can be slid to be aligned, so that the work efficiency is good. Furthermore, since it consists of a substantially square-shaped box, its strength is high. Further, by providing the positions of the bolt through holes symmetrically, it becomes possible to work without worrying about the difference between the upper and lower sides. Further, drilling of the beam material can be performed by computer control.

  Hereinafter, the best embodiment will be described with reference to FIGS. 1 to 3. FIG. 1 is an elevational view showing that a reinforcing member is applied to each of a pile head, a column base, and a column head. As shown in FIG. 1, several steel piles 1 are embedded in the ground 2, a beam material 3 is handed over it, and a column 5 is provided on the beam material 3 in a state of winning the beam. A steel frame structure in which the beam member 3, the column 5, and the beam member 3 are provided is a prerequisite. A brace material 7 is provided between the column 5 and the adjacent column 5. The reinforcement member 6 which concerns on this invention is provided in the position of a pile head, a column base, and a capital. As the beam member 3, lightweight steel, groove steel (C-shaped steel), H-shaped steel or the like is used. In the case of using a shape steel having upper and lower flanges on both sides of the rib like the H shape steel, the reinforcing member is provided on both sides. In the case of using a steel mold having upper and lower flanges on only one side, such as C-shaped steel, a reinforcing member is provided only on one side that is in contact with both the rib and the upper and lower flanges.

  FIG. 2 is a partially enlarged view showing an example in which the reinforcing member 6 is provided on the column base and the column head. Here, with respect to the upper column 5, the reinforcing member 6 is provided on the column base. Looking at the lower pillar 5, the reinforcing member 6 is provided at the top of the pillar. The beam member 3 is in a state of winning the beam with respect to the column 5. That is, the upper column 5 and the lower column 5 are divided and coupled to the beam member 3, respectively. The reinforcing member 6 is provided so as to contact the rib 3a and the upper and lower flanges 3b of the beam member 3. Further, bolt through holes are provided on the upper surface and the lower surface of the reinforcing member 6, and bolt through holes are also provided at corresponding positions of the upper and lower flanges 3 b of the beam member 3 and at corresponding positions of the columns 5. The bolt 5 passes through the beam flange 3b and the reinforcing member 6 and is tightened with a nut, whereby the column 5 and the beam material 3 are coupled.

  FIG. 3 is a diagram for explaining how to assemble the beam member 3 and the column 5. All of the beam members 3 are transported to the construction site in advance in the factory according to the design of the building. The column 5 is transported to the construction site in a state where the column 5 is coupled to the brace material 7. In addition, bolt through holes are formed in advance at positions where the beam member 3 is in contact with the upper and lower positions of the column 5. The reinforcing member 6 of the present invention is manufactured in advance as a standard product. Preferably, bolt through holes are formed at positions where they are balanced symmetrically even if they are rotated up and down. Since the self-supporting configuration is supported by the flange, it is easy to place the reinforcing member 6 on the flange of the beam member 3 and slide it to find the position where the bolt through hole is matched. Find the position where the pillar 5, the beam 3, the reinforcing member 6 and the bolt through holes of the three members are located, and pass the bolt. Then tighten the nuts to join them together. Therefore, the work efficiency at the construction site is high. Moreover, since it has a substantially square shape, the strength is also strong.

  FIG. 4 is a perspective view of the reinforcing member as a single unit. As shown in FIG. 4, it is a box made up of two upper and lower horizontal planes and two left and right vertical planes. Bolt holes 8 are preferably provided in a uniform position as standard products on the upper and lower horizontal planes. Even if it is rotated up and down, it is provided at a symmetrical position. The shape of the reinforcing member is a shape close to a rectangular parallelepiped, but has only upper, lower, left and right surfaces, and the front and rear are open. Accordingly, the four surfaces are in contact with the beam member 3. Using these open parts, bolts and nuts are fastened at the construction site. The four surfaces are joined at the factory in advance by bending or welding. In addition to the embodiment in which only the sides of the four surfaces are in contact with the beam member 3, it is also possible to have a structure consisting of five surfaces by attaching a steel plate to that portion.

  The embodiment of FIG. 5 is a view showing an example in which the rib member 9 is joined to the reinforcing member 6 to enable joining with the beam member. By joining the reinforcing member 6 with a rib member 9 of a size inscribed therein in advance with a bolt through hole welded thereto, and joining the beam member 4 with a bolt through hole preliminarily joined thereto with a bolt and a nut The three members of the pillar 5, the beam member 3, and the girder 4 can be joined.

  The embodiment of FIG. 6 is a view showing an example in which the rib member 10 is joined to the reinforcing member 6 to enable joining with the girders. The rib member 10 can be formed by replacing one of the four surfaces constituting the reinforcing member 6 with one having a larger size, or larger than the standard reinforcing member 6. The rib material 10 can be welded. Using this, it is possible to join the three members of the column 5, the beam member 3, and the girder member 4 as in the first embodiment shown in FIG. 5.

In FIG. 7, a beam member 3, a column 5, a beam member 3, a column 5 and a beam member 3 are provided on the steel pile 1, and a reinforcing member 6 is provided on each of the pile head, the column base, the column head, the column base, and the column head. It is a figure which shows providing. FIG. 8 is a perspective view showing the positional relationship between the pillar 5, the beam member 3, and the reinforcing member 6. Another reinforcing member is also provided on the shadow side of the beam member 3 and is indicated by a broken line. FIG. 9 is an example showing dimensions of the reinforcing member. In this example, the horizontal plane is 19 millimeters thick and the vertical plane is 16 millimeters thick. Both can be made of steel material. In FIG. 8, the orientation of the H steel as the column is 90 degrees different from the embodiment shown in FIG. 2 (in FIG. 2, the rib surface of the H steel of the column 5 is the rib surface of the H steel of the beam member 3. In the embodiment of FIG. 8, the directions are orthogonal to each other, but both embodiments are possible.

  The steel can be applied to lightweight steel, groove steel (C steel), H steel, and the like. And as a place to use, it is applicable to a pile head, a capital, and a column base.
