Description

Technical Field

[0001] The utility model belongs to the technical field of steel structure steel columns, and in particular relates to a steel column with a Japanese-shaped cross-section that is easy to manufacture. Background Art

[0002] Box-section steel columns and S-section steel columns are used to support the beams and columns of high-rise buildings to increase their strength. At present, the method of making S-section steel columns is to directly extend the middle web into the box and weld it to its web at the construction site of the steel structure. Due to the limited operating space in the box of the box-section steel column, the welding process is complicated, the number of welds is large, and deformation and dislocation will occur during splicing and welding, resulting in welding strength that does not meet the requirements. The welding personnel have high risks in working in the limited box space, which is time-consuming and labor-intensive and affects the construction progress of the steel structure. Summary of the invention

[0003] The utility model aims to solve the deficiencies of the prior art and provide a Japanese-shaped cross-section steel column which is easy to manufacture and has a simple splicing process, is not easy to be misaligned in splicing welding, has high welding quality and efficiency.

[0004] To achieve the above purpose, the solution adopted by the utility model is as follows:

[0005] A steel column with an I-shaped cross-section that is easy to manufacture comprises a box column assembled from two flange plates and two web plates, inner partitions respectively welded to the two ends of the box column, grooves respectively opened at the two ends of the box column, and middle web plates respectively inserted into the grooves; the inner ends of the middle web plates are welded to the inner partitions, and the grooves are opened on the web plates.

[0006] Furthermore, stiffening plates parallel to the inner partition plate are welded on both sides of the middle web plate.

[0007] Furthermore, two long sides of the two webs are provided with V20° grooves.

[0008] Furthermore, all welds are welded using gas shielded welding.

[0009] Compared with the prior art, the utility model has at least the following advantages:

[0010] The utility model has a simple structure. By grooving the web of the box-section steel column, the manufacturing method is decomposed into a box-type column unit and a "S"-shaped column unit. The two webs of the box-type column and the webs in the "S"-shaped column unit are grooved and welded, which effectively controls the deformation of the weld, improves the welding quality and efficiency, and avoids working in a limited space, reducing the risk of welding operations.

[0014] The utility model is further described in detail below in conjunction with the accompanying drawings of the specification.

[0015] refer to Figures 1 to 3 A steel column with a Japanese-shaped cross-section that is easy to make, comprising a box column assembled from two flange plates 1 and two webs 2, inner partitions 3 respectively welded to the two ends of the box column, grooves 5 respectively opened at the two ends of the box column, and middle webs 4 respectively inserted into the grooves; the inner end of the middle web is welded to the inner partition, the groove is opened on the web, and stiffening plates 6 parallel to the inner partition can be welded on both sides of the middle web, which makes the utility model more stable; V20° grooves are opened on the two long sides of the two webs, and all welds are welded by gas shielded welding, which effectively controls weld deformation and improves welding quality and efficiency.

[0016] Refer to Figures 1 to 3 A method for making a Japanese-shaped steel column that is easy to make is as follows:

[0017] Assembly of box-type column: the box-type column comprises a box-type assembled by two flange plates 1 and two web plates 2, and an inner partition plate 3 welded between the two web plates and on the lower flange plate 11; before assembly, check the straightness of the flange plate and the web plate and the dimensional deviation of each part, and assemble only after meeting the requirements. The assembly method of the box-type column is as follows: first fix the lower flange plate 11 on the processing frame, assemble the inner partition plate, and then assemble the two web plates. During the assembly process, control the verticality of the two web plates and the two flange plates, use positioning welding to fix the web plate and the lower flange, and do not assemble the upper flange plate 12 first;

[0018] Assembly of the "S"-shaped column: The "S"-shaped column includes a box-shaped column and a middle web 4 assembled between two webs at both ends of the box-shaped column; the assembly method of the "S"-shaped column is: grooves 5 are respectively opened on the two webs at both ends of the box-shaped column, the middle web is inserted into the groove and the three sides of the middle web are welded to the two webs of the box-shaped column and the inner partition, and then the upper flange plate is covered and the main weld is welded.

[0019] A stiffening plate 6 parallel to the inner partition can be set on the upper surface of the middle web and welded to the two webs and the inner partition of the box column, covered with an upper flange plate, and the main weld is welded to make the end of the Japanese-shaped column more stable.

[0020] Since the middle web is thick, it is necessary to open a groove on the middle web. A V20° groove can be opened on the two long sides of the two middle webs. The main weld is welded with a steel pad to achieve full penetration. The inner partition is partially welded with the two webs of the box column and the lower flange at a V30° groove, and is welded with the upper flange plate by electroslag welding. Or in step S2, a K-shaped groove is opened on the two long sides of the web, the grooves of the two webs of the box column are welded with the middle web by an anti-laminated tearing groove, a V-shaped groove is opened at the insertion end of the middle web and the inner partition, and a liner is placed on the insert end of the middle web for full penetration welding. A groove can also be opened on the middle web, and the anti-laminated tearing groove is used to weld the two webs of the box column, and the steel pad is placed on the inner partition for full penetration welding. In order to control the deformation during welding and ensure welding quality, all welds are welded by gas shielded welding.

[0021] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
