Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame structure for a steel frame building which has a simple structure, good workability and is inexpensive.

[0002]

2. Description of the Related Art When a steel frame structure is adopted as a one-story building or an equipment stand, a ramen structure or a brace structure is often used.

[0003]

However, when the rigid frame structure is used, it is necessary to rigidly join the joints between the column and the beam in both the X direction and the Y direction. Therefore, a square steel pipe is used for the column. Since it is used, the amount of steel frame increases, the amount of welding involved in joining the joints increases, and not only the construction cost becomes enormous, but also the construction requires labor. Also, when using the brace structure, since diagonal members are provided on the columns and beams,
A wall will be provided, and planar freedom will be lost.

In view of the above circumstances, it is an object of the present invention to provide a frame structure of a steel frame building which is simple in construction and good in workability.

[0005]

A frame structure of a steel frame building according to claim 1 is a frame structure of a steel frame building composed of a steel frame column and a beam, wherein the side surface of the column is A gusset plate is provided at a position opposed to each other with the center axis of the pillar interposed therebetween, and one of the adjacent pillars is rotated by 90 ° with respect to the mounting surface of the gusset plate, and a predetermined distance is maintained. Provide in X direction and Y
A plurality of the beams are arranged in the direction away from each other, and one end of the beam horizontally arranged so as to connect the adjacent columns is abutted face-to-face with the columns and fixed by a fixing means. The other end is fastened by fastening means via a gusset plate provided on the pillar.

According to a second aspect of the present invention, there is provided a frame structure for a steel frame building, wherein H-shaped steel is used for the columns, and the gusset plates are provided on both sides of a web of the columns.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The frame structure of a steel frame building of the present invention will be described in detail below with reference to FIGS. 1 to 3.

As shown in FIG. 1, a pillar 2 of a steel frame building 1
Is made of H-shaped steel, and gusset plates 6 are provided at desired height positions on both front and back sides of the web surface 2b. The plurality of pillars 2 having such a configuration are spaced apart in the X and Y directions with a predetermined distance.

The adjacent columns 2 are obtained by rotating the H-section steels by 90 ° so that one column 3 has a flange surface 2a and the other column 4 has a web surface 2b. The ones that do not rotate the orientation are set up alternately. The columns 2 arranged in this way are connected by the beams 5.

As shown in FIG. 2, the beam 5 is made of H-shaped steel similarly to the column 2. The beams 5 are horizontally arranged so as to connect the columns 2 adjacent to each other, and the beams 5 are continuously arranged to construct a frame structure of the steel frame building 1. At this time, one end 5a of the beam 5 is joined to one pillar 3 having the flange surface 2a as a joining surface, and the other end 5b is joined to the other pillar 4 having a web surface 2b as a joining portion. Will be done. Therefore, one end 5a of the beam 5 is
Then, the other end portion 5b has a different joining structure to the pillar 2. The joint structure of both is shown below.

As shown in FIG. 3 (a), the joint structure between one end 5a of the beam 5 and one pillar 3 forming the flange surface 2a is formed on the flange surface 2a of the one pillar 3. The one end 5a of the beam 5 is butted against each other and fixed by means of welding or the like, and a rigid joint is formed.

As shown in FIG. 3 (b), the joining structure between the other end 5b of the beam 5 and the other pillar 4 forming the web surface 2b has a structure in which the other pillar 4 has a web surface 2b. The gusset plate 6 is provided at a desired height position,
The other end 5a of the beam 5 is superposed on the gusset plate 6 and fastened by means of a bolt 7 or the like.
A pin junction is formed.

In the present embodiment, the H-shaped steel is used for the column 2, but the present invention is not limited to this. The gusset plates 6 may be provided on the two opposite surfaces using a square steel pipe. As described above, the present embodiment is merely an example, and it goes without saying that the present invention is not limited to the present embodiment and any form can be adopted without departing from the spirit of the present invention.

According to the structure described above, in the frame structure of the steel building 1, the beam 5 rigidly joins one end 5a to the column 2 and the other end 5b to the column 2. Since the structure in which the pins are joined together via the gusset plate 6 provided in 2 is continuous in both the X direction and the Y direction, the joint structure of the beam 5 and the column 2 can be simplified and welded. The amount can be reduced and the workability can be improved.

Further, since the H-shaped steel can be used for the pillar 2, the amount of steel frame can be significantly reduced as compared with the case where a rectangular steel pipe or the like is used, which can greatly contribute to the reduction of the construction cost. .

Further, in the frame structure of the steel building 1, since a rigid structure can be formed under the load in the vertical direction and the horizontal direction as in the case of using the rigid frame structure, it is not necessary to use braces, and the beam is not necessary. It is possible to effectively use the lower space.

[0017]

According to the frame structure of a steel frame building according to claim 1, in a frame structure of a steel frame building composed of a steel frame column and a beam, a pillar is provided on a side surface of the column. A gusset plate is provided at a position facing each other across the central axis of, and one of the adjacent columns is
The mounting surface of the gusset plate is rotated by 90 °, and a plurality of the gusset plates are spaced apart in the X direction and the Y direction at a predetermined distance, and are horizontally arranged so as to connect the adjacent columns. One end of the beam is face-to-face with the pillar and fixed by a fixing means, and the other end is fastened by a fastening means via a gusset plate provided on the pillar. Therefore, the joint structure of the beam and the column can be simplified, the amount of welding can be reduced, and the workability can be improved.

Further, in the frame structure of the steel frame building, since a rigid structure can be formed under the load in the vertical direction and the horizontal direction as in the case of using the rigid frame structure, there is no need to use braces, It is possible to effectively use the space.

According to the frame structure of the steel frame building of claim 2, since the H-section steel is used for the column and the gusset plates are provided on both sides of the web of the column, The joint structure of beams and columns can be simplified and the amount of steel frame can be significantly reduced, which can greatly contribute to the reduction of construction costs.
