Abstract

PURPOSE:To secure required structural strength by adopting partially or totally concrete-filled posts and non-concrete-filled posts which are laid out in an outside wall cornered part, an outside wall middle part and a partitioning wall cornered part and a partitioning middle part. CONSTITUTION:An L-shaped cross section post 20 is laid out at an outside wall cornered part while a T-shaped cross section steel pipe post 30 is laid out at an outside middle part. Furthermore, a cross-shaped cross sectional steel pipe 40 is laid out at a partitioning wall cornered part. In the L-shaped cross section steel pipe post 20, beams are joined in the two directions where a post/ beam joint part are continuously installed at the tip of two branch blades, thereby forming a concrete-filled type post. Then, the T-shaped cross section steel pipe post 30 and the cross-shaped cross section steel pipe post 40 are specified as a concrete-filled type, thereby forming a concrete-filled opening on an inner reinforced board at the core. It is, therefore, possible to expand an effective space of a chamber or a segment.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building, such as a commercial building, an office building, a hotel, a house, etc., which uses steel pipe columns.

[0002]

2. Description of the Related Art A skeletal structure of a building is composed of columns, walls and beams, and the effective space of each room for living, working, and sales of the building and the compartments for facilities such as elevators is the outer wall. It depends on the size of the cross-sectional area of each of the columns arranged in the corner portion, the outer wall intermediate portion, the partition wall corner portion or the partition wall intermediate portion.

Steel pipe columns used in conventional buildings are
Concrete filled type or non-filled type circular steel tubular columns and square steel tubular columns, but in buildings using circular steel tubular columns, a fan-shaped or arc-shaped portion that is not convenient to use is formed, while shown in Fig. 2. As described above, in the building 1 using the square steel pipe columns 2, one corner is provided for each of the outer wall corner portion and the partition wall corner portion, and two each is provided for each of the outer wall intermediate portion and the partition wall intermediate portion. Since the part overhangs to the room or compartment side, the dead space is large, and this tendency becomes more remarkable as the diameter of the steel pipe column increases with the height of the building, and the effective space 3 shown by diagonal lines decreases. go.

The present inventors have moved away from the existing concept that a steel pipe column has a circular or square cross section, and conducted research and development on the possibility of a steel pipe column having an irregular cross section. The present invention was completed by finding that a building having sufficient structural strength can be obtained even with a steel pipe column.

[0005]

That is, an object of the present invention is to provide a building using steel pipe columns, which can increase the effective space of a room or a compartment while ensuring a required structural strength. Is.

[0006]

A building 10 using a steel pipe column according to the present invention will be described below with reference to the reference numerals in the attached drawings. The building 10 includes an outer wall corner portion, an outer wall intermediate portion, a partition wall corner portion, and a partition wall. Part or all of the columns arranged in the middle part of the wall or the like are configured with concrete-filled or non-concrete-filled L-section steel pipe columns 20, T-section steel pipe columns 30, and cross-section steel pipe columns 40.

[0007]

As shown in FIG. 1, the L-shaped steel pipe column 20 in cross section is arranged in the outer wall corner part, the T-shaped steel pipe column 30 in cross section is arranged in the outer wall middle part, and the cross-shaped steel pipe column 40 is formed in the partition wall corner part. When arranged, an effective space 50 indicated by diagonal lines is obtained in each room or compartment.

The conventional building 1 of FIG. 1 and the building 10 of the present invention of FIG. 2 have the same column arrangement distance d, and the two branching blade portions of the L-shaped steel pipe column 20 and the T-shaped steel pipe section. In the three branch blades of the column 30 and the four branch blades of the cross-section steel pipe column 40, the protrusion length from the core portion shared by the branch blades is the length a of one side of the square steel pipe column 2. It is half of.

When the effective space 3 of the room of the conventional building 1 and the effective space 50 of the room of the building 10 of the present invention are compared under this set condition, the building 10 of the present invention is equivalent to 2 ad. It's just getting wider.

Two branch wings of the L-shaped steel pipe column 20 having a cross section,
The three branch wings of the T-section steel pipe column 30 and the four branch wings of the cross-section steel pipe column 40 are reinforcing elements against each other against bending load and shear load of the other branch blade parts, and thus these The steel pipe column having a modified cross section functions as a structural member having a sufficiently high bending strength, shear strength, etc. in the building 10.

[0011]

INDUSTRIAL APPLICABILITY As described above, in the building of the present invention, some or all of the columns arranged in the outer wall corner portion, outer wall middle portion, partition wall corner portion, partition wall middle portion, etc. are filled with concrete or concrete. Filled cross-section L-shaped steel pipe column 2
0, T-section steel pipe column 30 or cross-section steel pipe column 40
Since it is configured as described above, the effective space 50 of the room or the partition can be expanded while ensuring the required structural strength, and the degree of freedom in the floor plan of the building is increased.

EXAMPLE In each of the examples shown in FIGS. 3 to 7, each of the steel pipe columns 20, 30, and 40 is of a synthetic type made by welding and assembling steel plates having required lengths, widths, and thicknesses at right angles to each other. It is a steel pipe pillar. In the steel tube column 20 having an L-shaped cross section shown in FIGS. 3 and 4, the beam 60 is joined in four directions, and the ends of the two branch wings 20b and one side of the core portion 20a have a beam-column joint portion. 21 are connected in advance. Core part 20
A beam 60 is directly welded to the other side surface of a. This steel pipe column 20 is a concrete filling type, and a filling opening 23 is formed in the core portion 20a and the internal reinforcing plate 22 of each branch wing portion 20b.

The L-shaped steel pipe column 20 shown in FIG. 5 has a beam 60 joined in two directions, and a column-beam joint 21 is connected in advance to the tips of the two branch wings 20b. is there. In the T-section steel pipe column 30 shown in FIG. 6, the beams 60 are joined in three directions, and three branch wing portions 30b are provided.
A beam 60 is directly welded to this. This steel pipe column 30 is a concrete-filled type, and the internal reinforcing plate 3 of the core portion 30a
2 has a filling opening 33 formed therein.

In the cross-section steel pipe column 40 shown in FIG. 7, the beams 60 are joined in four directions, and the beams 60 are directly welded to the tips of the four branch wings 40b. The steel pipe column 40 is a concrete filling type, and a filling opening 43 is formed in the internal reinforcing plate 42 of the core portion 40a.
A T-shaped internal reinforcing plate is welded to each of the branch wings 40b.

In any of the L-shaped section steel tube column 20, the T-section section steel tube column 30 and the cross-section section steel tube column 40, the length ratio of the branch wing portion to the core portion is not limited to that shown in the figure, and It is appropriately changed according to various design conditions. Further, the joining of the steel pipe column and the beam or the wall panel, and the construction of other building parts are performed by appropriately selecting a known method.
