。As shown in FIGS. 1 and 2, the steel pipe column 7 has a thickness of T.
A stiffener assembly 6 connects the steel pipes 3.3 between the steel pipes 3.3, and a panel zone 1. It is set up in such a way that it forms a The stiffener assembly 6 has a cylindrical connecting tube 5 with a square cross section, and the connecting tube 5 has a thickness T.
2 is formed of a steel plate thicker than the thickness T1 of the steel pipe 3, and its inner dimension D1 is smaller than the inner dimension D3 of the steel pipe 3, and its outer dimension D2 is larger than the outer dimension D4 of tll'ff3. It is formed. Furthermore, stiffeners 2.2 are connected to the upper and lower sides of the connecting pipe 5 of the stiffener assembly 6 in FIG. As shown in FIG. 2, each stiffener 2 has a main body 2a formed entirely in a square plate shape, and most of the main body 2a is disposed on the inner peripheral side of the steel pipe 3, and only the outer edge 2b but,
It protrudes toward the outer periphery and is connected to the surrounding beams 9 via the outer edge portion 2b. A concrete flow hole 2c is connected to the center of the main body 2a so that the inside and outside of the connecting pipe 5 are communicated with each other.

易に行うことが出来ろ。Since the steel pipe column 7 has the above configuration, the steel pipe column 7
When constructing a steel pipe 3, first install the steel pipe 3 shown in the lower part of FIG. The stiffener 2 and steel pipe 3 at the bottom of FIG. 1 are connected by welding. At this time, the connection between the steel pipe 3 and the stiffener assembly 6 is as follows.
In order to smoothly transmit stress in the vertical direction in FIG. 1 between the steel pipe 3 and the stiffener assembly 6, it is necessary that the connecting pipe 5 of the tlII pipe 3 and the stiffener assembly 6 be connected without misalignment. Therefore, when welding, it is necessary to align the connecting pipe 5 and the steel pipe 3, but the inner dimension D1 of the connecting pipe 5 is smaller than the inner dimension D3 of the steel pipe 3, and the outer dimension D2 is smaller than the outer dimension D4 of the steel pipe 3. Since the connecting tube 5 is formed in a larger shape, it absorbs errors in the horizontal direction in the figure that occur when the connecting tube 5, which has a large difference in inside and outside dimensions, is aligned with the N4 tube 3.
When aligning the steel pipes 3 and 3, there is less risk of the pipes shifting in the left-right direction in Figure 1 than when the inner and outer dimensions D1, D3 and D2, D4 of the connecting pipe 5 and the N4 pipe 3 are equal. You can do it easily.

が出来る。Next, the steel pipe 3 is similarly installed above the installed stiffener assembly 6 in FIG. Join the stiffener 2 on the top of 6. At this time as well, steel pipe 3
The matching work between the connecting pipe 5 and the connecting pipe 5 is performed by checking that the difference in the inside and outside dimensions of the connecting pipe 5 is
Since the difference in dimensions between the inside and outside of the steel pipe 3 is larger, this can be done easily.

管柱7の構築を完了する。In this way, when the W4 pipe 3.3 is connected in the vertical direction via the stiffener assembly 6, the beam 9 is installed to be connected to each stiffener 2.2 of the stiffener assembly 6, and connections are made as necessary. Rod pipe 3.3 and stiffener assembly 6
Concrete and mortar are poured into the connecting pipe 5 to complete the construction of the steel pipe column 7.

させろことが出来る。In addition, in the above-mentioned embodiment, the inner dimension D1 of the connecting pipe 5 is
smaller than the inner dimension D3 of the steel pipe 3 (and whose outer dimension D2 is smaller than the inner dimension D3 of the steel pipe 3)
As described above, the outer dimension D2 of the connecting pipe 5 is larger than the outer dimension D4 of the steel pipe 3.
4 and the inner dimension D1 is smaller than the inner dimension D3 of the m pipe 3, or the inner dimension D1 is equal to the inner dimension D3 of the steel pipe 3 and the outer dimension D
2 may be formed to be larger than the outer dimension D4 of the steel pipe 3. However, in the case of B, the connection between the steel pipe 3 and the connecting pipe 5 on either the inner diameter side or the outer diameter side will be misaligned due to misalignment. The stress transmission state is worse than when the inner dimension D1 of the connecting pipe 5 is smaller than the inner dimension D3 of the steel pipe 3 and the outer dimension D2 is larger than the outer dimension D4 of the steel pipe 3. There is a danger. However, this effect can be significantly reduced compared to when both the steel pipe 3 and the connecting pipe 5 are formed with the same internal and external dimensions.

な応力の伝達を行うことが出来ろ。As described above, according to the present invention, in the panel zone 1, the two stiffeners 2.2 that protrude the W4 pipe 3.3 toward the inner peripheral side of the steel pipe 3 and the stiffener 2 .2, the inner dimension D1 of the connecting pipe 5 is made smaller than the inner dimension D3 of the steel pipe 3, or the outer dimension D2 of the connecting pipe 5 is made smaller than the steel pipe 3. The diameter of the tube is larger than the outer dimension D4 (D4), so the alignment between the steel pipe 3 and the connecting pipe 5 allows for more error than when using the connecting pipe 5 and the steel pipe 3 with the same inner and outer dimensions. This makes it possible to perform the work without requiring a high degree of skill.Also, since the difference between the inside and outside dimensions of the connecting pipe 5 is larger than the difference between the inside and outside dimensions of the steel pipe 3, the difference between the inside and outside dimensions of the connecting pipe 5 and the steel pipe 3 Even if the alignment is misaligned, it is easy to ensure a sufficient connecting cross-sectional area between the steel pipe 3 and the connecting pipe 5, and smooth stress transmission can be achieved.
