Description

Technical Field

[0001] The utility model relates to the technical field of steel structure factory building construction, in particular to an H-shaped cross-section steel column of a large-span steel structure factory building. Background Art

[0002] H-beams, also known as I-beams, have a cross-sectional shape similar to the Chinese character "I," with wide upper and lower flanges and a thin central web. This design makes I-beams highly efficient in resisting bending and shear forces. Compared to other profiles, I-beams offer a greater moment of inertia and bending modulus for the same weight, effectively reducing cross-sectional dimensions and increasing building space utilization. They are particularly well-suited for large-span, heavy-load factory buildings.

[0003] In the existing technology, the span of a large-span factory building is large, so the steel structure factory building requires more support. A number of piles are set at the bottom of the factory building, and then a square tube steel column is connected to each pile. The position near the interior of the factory building will be supported by I-beams. When the I-beams are connected, generally after the foot columns are buried in the ground, corresponding embedded bolts will be set on the foot columns, and then the I-beams are connected to the foot columns through the embedded bolts, thereby achieving the effect of I-beam connection. However, since a large-span steel structure factory building requires a large number of I-beams, it takes more time to spend on the bolt connection part, which affects the installation efficiency of the steel structure factory building. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an H-shaped cross-section steel column for a large-span steel structure factory building, so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A large-span steel structure factory building H-shaped cross-section steel column includes a foot pile column, an I-beam column is provided on the top of the foot pile column, two inner recesses of the I-beam column are respectively provided with a first steel plate and a second steel plate, and a fixed joint member is provided between the first steel plate and the second steel plate;

[0007] The fixed docking parts include two cavity columns, two insertion columns and two triangular columns. The two cavity columns are fixedly installed on the side of the steel plate one close to the I-beam column, and the two insertion columns are fixedly installed on the side of the steel plate two close to the I-beam column. The two triangular columns are respectively inserted into the corresponding cavity columns. A triangular groove corresponding to the triangular column is opened on the bottom side of the middle part of the I-beam column, and the end of the triangular column passes through the corresponding triangular groove and is inserted into the corresponding insertion column.

[0008] In a preferred example, the present invention can be further configured as follows: a circular groove 1 is provided at one end of the insertion column away from the I-beam column, a circular groove 2 is provided on the side of the second steel plate at a position corresponding to the circular groove 1, a spring is connected to the inner end side wall of the circular groove 2, and the end of the triangular column is connected to the spring.

[0009] In a preferred example, the present invention can be further configured as follows: an end of the triangular column away from the first steel plate is connected to a pull rod, and an end of the pull rod extends to the side of the second steel plate and is connected to a limiting rod.

[0010] In a preferred example, the present invention can be further configured as follows: a push rod is provided at one end of the triangular column away from the I-beam column, and the push rod is slidably connected to the steel plate.

[0011] In a preferred example, the present invention can be further configured as follows: a number of embedded steel bars are embedded in the top of the foot pile column, the bottom end of the I-beam column is sleeved on the corresponding embedded steel bars, and the steel plate 1 and the steel plate 2 are respectively sleeved on the corresponding embedded steel bars.

[0012] In summary, the present invention has at least one of the following beneficial technical effects:

[0013] 1. This H-shaped steel column for a large-span steel structure factory building can be directly inserted between the first and second steel plates during use, and then locked with a triangular column. This eliminates the need for bolting the I-beam column, thereby saving time on tightening the bolts and improving the installation efficiency of the I-beam column.

[0014] 2. In this H-shaped steel column of a large-span steel structure factory building, the provided tie rods and limit rods cooperate. When pulling the triangular column, the limit rod is directly pulled. The limit rod will drive the triangular column to move away from the first steel plate through the tie rod, and then facilitate the insertion of the I-beam between the first and second steel plates. The provided tie rods and limit rods facilitate the pulling of the triangular column, thereby facilitating the installation of the I-beam.

[0015] 3. This H-shaped steel column for a large-span steel structure factory building has a push rod that pushes the push rod to move the triangular column toward the second steel plate when moving the triangular column, and then causes the limiting rod to separate from the first steel plate, thereby facilitating the movement of the triangular column through the limiting rod and the pull rod. The push rod is then pulled back to its original position, thereby facilitating the movement of the triangular column to install the I-beam column;

[0016] 4. The H-section steel columns of this large-span steel structure factory building are provided with embedded steel bars to limit the position of the I-beam columns when placing them. After the I-beam columns are inserted with the embedded steel bars, the I-beam columns can be directly pressed down without the need for subsequent position adjustment. The steel plates one and two are placed on the corresponding embedded steel bars to limit the positions of the steel plates one and two, so as to facilitate the subsequent direct installation of the I-beam columns.

[0025] The fixed docking part 5 includes two cavity columns 6, two insertion columns 7 and two triangular columns 8. The two cavity columns 6 are fixedly installed on the side of the steel plate 3 close to the I-beam column 2, and the two insertion columns 7 are fixedly installed on the side of the steel plate 2 4 close to the I-beam column 2. The two triangular columns 8 are respectively inserted into the corresponding cavity columns 6. A triangular groove 9 corresponding to the triangular column 8 is opened on the bottom side of the middle part of the I-beam column 2, and the end of the triangular column 8 passes through the corresponding triangular groove 9 and is inserted into the corresponding insertion column 7.

[0026] In this embodiment, before installing the I-beam, steel plate 1 3 and steel plate 2 4 are preferably buried on the top side of the foot pile column 1, wherein the cavity column 6 is integrally formed with steel plate 1 3, and the insertion column 7 is integrally formed with steel plate 2 4, and then the triangular column 8 is inserted into the insertion column 7, and then the I-beam column 2 is inserted from top to bottom between steel plate 1 3 and steel plate 2 4, so that steel plate 1 3 and steel plate 2 4 are respectively inserted into the two concave parts of the I-beam column 2, and then the triangular column 8 is inserted into the triangular groove 9, so as to achieve the effect of fixing the I-beam column 2, wherein when installing the I-beam column 2, the I-beam column 2 can be directly inserted into the corresponding position, and then the triangular column 8 can be pushed to fix the I-beam.

[0027] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a circular groove 11 is provided at one end of the insert column 7 away from the I-beam column 2, a circular groove 12 is provided on the side of the steel plate 4 at a position corresponding to the circular groove 11, a spring 13 is connected to the inner end side wall of the circular groove 12, and the end of the triangular column 8 is connected to the spring 13.

[0028] In this embodiment, in order to prevent the triangular column 8 from shifting in position after long-term use, before the I-beam column 2 is inserted between the steel plates 1 3 and 2 4, a circular groove 11 is opened at the end of the insertion column 7, and a circular groove 2 12 is opened on the side of the steel plate 2 4, and a spring 13 is installed in the circular groove 2 12 so that the end of the spring 13 is connected to the triangular column 8. Then, when the I-beam column 2 is inserted between the steel plates 1 3 and 2 4, the triangular column 8 is first pushed to move in the direction of the circular groove 2 12 while squeezing the spring 13. Then, when the bottom end of the I-beam column 2 is fitted with the top side of the foot pile column 1, the triangular column 8 is released. The triangular column 8 will be subjected to the reaction force of the spring 13 to pass through the triangular groove 9 and be inserted into the cavity column 6, thereby completing the effect of automatic positioning and improving the efficiency of the I-beam installation.

[0032] In this embodiment, when the push rod 10 is provided to move the triangular column 8, the push rod 10 drives the triangular column 8 to move toward the direction of steel plate 2 4, and then the limiting rod 15 is separated from steel plate 1 3, thereby facilitating the movement of the triangular column 8 by the limiting rod 15 and the pull rod 14, and then the push rod 10 is pulled to the original position, thereby facilitating the movement of the triangular column 8 to install the I-beam column 2.

[0033] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a number of embedded steel bars 16 are embedded in the top of the foot pile column 1, the bottom end of the I-beam column 2 is sleeved on the corresponding embedded steel bars 16, and the steel plate 1 3 and the steel plate 2 4 are respectively sleeved on the corresponding embedded steel bars 16.
