Description

Technical Field

[0001] The utility model relates to the field of steel structure factory building installation engineering, in particular to a steel column verticality adjustment device. Background Art

[0002] When installing a steel structure factory building, the steel columns must be installed first. The steel columns' baseplates have pre-set holes. Anchor bolts embedded in the concrete foundation are inserted into these holes, allowing the steel columns to be placed on the concrete foundation. The verticality of the steel columns is then precisely adjusted. Once the steel columns are perfectly vertical, a second cast-in-place process is performed to fill the gap between the steel column baseplate and the top surface of the concrete foundation, completely securing the steel columns to the concrete foundation.

[0003] The traditional method for adjusting the verticality of steel columns involves pulling the top of the columns with multiple guy ropes and then straightening them. This process requires multiple operators working simultaneously, wasting manpower. Furthermore, since the guy ropes are flexible components, they are easily disturbed by external factors. This makes it difficult for the steel columns to maintain a vertical position during the secondary pouring process after vertical adjustment, compromising the quality of the steel column installation. Utility Model Content

[0008] The lower connecting seat includes a bottom plate and a fourth ear plate; the fourth ear plate is connected to the top of the bottom plate; the bottom plate is connected to the ground; and the fourth ear plate is hinged to the second ear plate.

[0009] Furthermore, the first oblique connecting rod and the second oblique connecting rod are both H-shaped steels.

[0010] Furthermore, the H-shaped steel of the first oblique connecting rod is connected to a first stiffening rib near its lower end, and the H-shaped steel of the second oblique connecting rod is also connected to a first stiffening rib near its upper end.

[0011] Furthermore, the first oblique connecting rod and the second oblique connecting rod have the same structure; the first oblique connecting rod includes two channel steels; the webs of the two channel steels are arranged back to back; and further includes multiple connecting plates; the connecting plates connect the flange plates of the two channel steels.

[0026] The upper end of the first oblique connecting rod 1 is connected to the first ear plate 1b, and the lower end of the second oblique connecting rod 2 is connected to the second ear plate 2b;

[0027] It also includes an upper connecting seat and a lower connecting seat; the upper connecting seat includes a side plate 5, a third ear plate 5a, and a U-shaped snap ring 5b; the third ear plate 5a is connected to the side plate 5, and the U-shaped snap ring 5b is sleeved on the outside of the steel column, and the open end of the U-shaped snap ring 5b passes through the side plate 5 and is locked by a nut; the third ear plate 5a is hinged to the first ear plate 1b;

[0028] The lower connecting seat includes a bottom plate 6 and a fourth ear plate 6a; the fourth ear plate 6a is connected to the top of the bottom plate 6; the bottom plate 6 is connected to the ground; the fourth ear plate 6a is hinged to the second ear plate 2b.

[0029] In this embodiment, the third ear plate 5a and the first ear plate 1b both have through holes, and the third ear plate 5a is hinged to the first ear plate 1b by a pin passing through the through hole. The third ear plate 5a and the first ear plate 1b can also be hingedly connected using other methods in the existing technology; the fourth ear plate 6a and the second ear plate 2b both have through holes, and the fourth ear plate 6a is hinged to the second ear plate 2b by a pin passing through the through hole. The fourth ear plate 6a and the second ear plate 2b can also be hingedly connected using other methods in the existing technology.

[0030] First, use the lifting equipment to lift the steel column to the foundation concrete position. The steel column is placed on the foundation concrete through the reserved holes of its bottom plate and the anchor bolts are inserted into the corresponding holes. During operation, put the U-shaped clamping ring 5b on the steel column, as shown in the figure. Figure 1 、 Figure 2 As shown, there are two U-shaped clamping rings 5b. Nuts are used to tighten the open ends of the U-shaped clamping rings 5b against the side panels 5, thereby securing the U-shaped clamping rings 5b to the steel columns. The base plate 6 has four small holes in the front, back, left, and right sides. Expansion bolts are driven through these holes to secure the base plate 6 to the ground. Other methods of attaching the base plate 6 to the ground are also possible.

[0031] Use a tool to loosen the nuts on both sides of the second end plate 2a, then move the screw 3, and then rotate the nuts on both sides to tighten against the second end plate 2a, so as to adjust the distance between the first oblique connecting rod 1 and the second oblique connecting rod 2; Figure 1 When the distance between the first and second diagonal connecting rods 1 and 2 increases, the steel column tilts to the right, driven by the U-shaped clamping ring 5b. When the distance between the first and second diagonal connecting rods 1 and 2 decreases, the steel column tilts to the left, driven by the U-shaped clamping ring 5b. This operation adjusts the verticality of the steel column. A level bubble installed on the steel column or other existing methods is used to check whether the steel column is completely vertical. If it is not completely vertical, the above operation is repeated until the steel column is completely vertical. After the steel column is completely vertical, the gap between the steel column base plate and the foundation concrete is poured a second time to completely fix the steel column to the foundation concrete. After that, the device can be removed.

[0032] When the utility model is used, the operator loosens the nuts on both sides of the second end plate 2a with a tool, then moves the screw 3, and then rotates the nuts on both sides to press against the second end plate 2a, thereby adjusting the distance between the first oblique connecting rod 1 and the second oblique connecting rod 2; Figure 1 When the distance between the first oblique connecting rod 1 and the second oblique connecting rod 2 increases, the steel column tilts to the right under the drive of the U-shaped clamping ring 5b; when the distance between the first oblique connecting rod 1 and the second oblique connecting rod 2 decreases, the steel column tilts to the left under the drive of the U-shaped clamping ring 5b, and the verticality of the steel column is adjusted through this operation; this operation process only requires one operator to complete, saving manpower, and the first oblique connecting rod 1 and the second oblique connecting rod 2 play a stable diagonal support role for the steel column, which can keep the steel column in a vertical state at all times during the secondary pouring process, ensuring the installation quality of the steel column.

[0036] In this embodiment, when the first oblique connecting rod 1 and the second oblique connecting rod 2 jointly support the steel column, the connection position of the first oblique connecting rod 1 and the second oblique connecting rod 2 is easily damaged due to stress concentration. The first oblique connecting rod 1 is reinforced by providing a first stiffening rib near the lower end of the H-shaped steel and the second oblique connecting rod 2 is reinforced by providing a first stiffening rib near the upper end of the H-shaped steel to prevent damage.
