Description

Technical Field

[0001] The present invention belongs to the technical field of steel structure rocking column installation, and in particular relates to an auxiliary installation device for a steel structure rocking column. Background Art

[0002] The swing column is a very common component in steel structure buildings. Its column body is usually in the shape of a rectangular parallelepiped. Both ends of the swing column in the vertical direction are hinged to the pre-set nodes on the steel structure building to provide vertical support for the structure without changing the lateral stiffness of the structure. Since the stability of the swing column itself depends on the lateral stiffness of the steel frame, it is easy to become unstable during construction. Temporary support of the swing column is required in turn to ensure normal construction. Existing temporary support for the swing column usually fixes the ends of multiple cables to the swing column and tightens them in multiple directions. Since the cables are flexible, when adjusting the verticality of the swing column, it is necessary to loosen and tighten the cables in two opposite directions at the same time, which is difficult to adjust and needs to be improved.

[0003] At present, existing steel structure rocking columns are often easily affected by wind during installation, resulting in poor stability and high axial stiffness, making them prone to breakage. Summary of the Invention

[0004] In view of this, the present invention provides an auxiliary installation device for a steel structure rocking column, aiming to solve the problems of the existing steel structure rocking column being easily affected by wind during installation, resulting in poor stability, large axial stiffness and easy breakage.

[0005] The present invention is achieved in that:

[0006] The present invention provides an auxiliary installation device for a steel structure rocking column, which comprises a column body, a receiving base being provided at the bottom of the column body, the column body being fixedly connected to the receiving base, a supporting inclined column being provided at the bottom of the receiving base, a connecting plate being provided at the bottom of the supporting inclined column, a supporting column being provided at the bottom of the connecting plate, an internal cavity being provided inside the column body and the supporting column, and an internal supporting mechanism being provided inside the internal cavity.

[0007] The technical effects of the auxiliary installation device for a steel structure rocking column provided by the present invention are as follows: by adopting a connecting plate to connect the supporting inclined column and the receiving base, the connecting plate uses the geometric characteristics of the structural system to construct a three-dimensional seismic isolation (vibration) system, which can well solve the column rocking problem. Since the axial stiffness of the column is large and the lateral stiffness is much smaller, it can have a large vertical deformation; the geometric shape of the connecting plate can better ensure the stability of the system, so that the structure is decoupled horizontally and vertically; by completing the installation of the internal cavity and the internal support mechanism at the same time during the manufacturing and installation process of the column and the supporting column, there is no need to subsequently add damper fixing devices and equipment, thereby improving the economy and reliability of the column and the supporting column.

[0008] On the basis of the above technical solution, the auxiliary installation device for a steel structure rocking column of the present invention can also be improved as follows:

[0009] Wherein, the supporting base includes an upper supporting chassis and a lower supporting chassis, the upper supporting chassis is arranged at the bottom of the column, and the lower supporting chassis is arranged at the top of the supporting inclined column, and the upper supporting chassis and the lower supporting chassis are fixedly connected by bolts.

[0010] Furthermore, the lower supporting chassis includes a central supporting plate and a lateral support rod, the central supporting plate is fixedly connected to the bottom of the lower supporting chassis, one end of the lateral support rod is fixedly connected to the central supporting plate, and the other end of the lateral support rod is fixedly connected to the connecting plate.

[0011] Wherein, the connecting plate includes an upper connecting plate, a lower connecting plate, a first supporting spring and a second supporting spring, the upper connecting plate is fixedly connected to the bottom of the supporting inclined column, the lower connecting plate is fixedly connected to the top of the supporting column, an upper connecting column is provided at the bottom of the upper connecting plate, and a lower connecting column is provided at the top of the lower connecting plate, the first supporting spring is provided at the end of the upper connecting column, and the second supporting spring is provided at the end of the lower connecting column.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are: using the geometric characteristics of the structural system, utilizing the upper connecting plate, the lower connecting plate, the first support spring and the second support spring, a three-dimensional seismic isolation (vibration) system is constructed, which can effectively solve the column swing problem. Since the axial stiffness of the column is large and the lateral stiffness is much smaller, it can have a large vertical deformation; the geometric shape of the upper connecting plate and the lower connecting plate can better ensure the stability of the system, so that the structure is decoupled horizontally and vertically.

[0013] Furthermore, the number of the upper connecting columns is 4, and the number of the lower connecting columns is 8.

[0014] Wherein, the interior of the internal cavity is filled with damping fluid.

[0015] Among them, the internal support mechanism includes an upper top plate, an intermediate column and a lower top plate. The upper top plate is fixedly connected to the top of the internal cavity, the lower top plate is fixedly connected to the bottom of the internal cavity, and the upper top plate and the lower top plate are connected through the intermediate column.

[0016] The beneficial effect of adopting the above-mentioned improvement scheme is that the installation of the internal cavity and the internal support mechanism is completed simultaneously during the manufacturing and installation process of the column and the supporting column, without the need to subsequently add damper fixing devices and equipment, thereby improving the economy and reliability of the column and the supporting column.

[0017] Wherein, it also includes a ground fixing mechanism, which is arranged on the side wall of the column and is used to fix the column to the ground.

[0018] Furthermore, the ground fixing mechanism includes a fixed frame, a support pier, a shock-absorbing block, an underground column, a hydraulic valve and an inverted support beam. The bottom of the fixed frame is fixedly connected to the support pier, the bottom of the support pier is provided with the shock-absorbing block, the shock-absorbing block is fixedly connected to the underground column, and the hydraulic valve is provided on the side wall of the underground column.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: a fixed frame is set under the industrial equipment, and the fixed frame is placed on the supporting pier. There will be a gap between the column and the fixed frame. A shock-absorbing block is set under the supporting pier, and the top of the shock-absorbing block is made of steel plate. When the jack is placed under the fixed frame, the pressure of the supporting pier is released, the steel plate is removed, and the material in the shock-absorbing block is replaced according to different shock forces to achieve the best shock-absorbing effect. At the same time, an underground column is set under the shock-absorbing block to transmit the shock force to the deep soil. The supporting force of the ground fixing mechanism is effectively improved by grouting the bottom of the underground column and grouting the side. First, the anti-liquefaction ability of the vertical component is improved. The ground fixing mechanism forms a frame of concrete inverted support beams, which effectively suppresses the liquefaction phenomenon of the soil. In addition, a geotextile is set between the ground fixing mechanism and the foundation soil to adjust the displacement difference between the foundation soil particles, which also has a certain effect on reducing the liquefaction of the soil under the foundation.

[0020] Furthermore, the supporting pier, the shock absorbing block, the underground column and the hydraulic valve constitute a shock absorbing assembly, and the inverted support beam is sleeved on the outside of the shock absorbing assembly.

[0021] Compared with the prior art, the beneficial effects of the auxiliary installation device for a steel structure swing column provided by the present invention are: by adopting a connecting plate to connect the supporting inclined column and the receiving base, the connecting plate uses the geometric characteristics of the structural system to construct a three-dimensional seismic isolation (vibration) system, which can well solve the column swing problem. Since the axial stiffness of the column is large and the lateral stiffness is much smaller, it can have a large vertical deformation; the geometric shape of the connecting plate can better ensure the stability of the system, so that the structure is decoupled horizontally and vertically; by completing the installation of the internal cavity and the internal support mechanism at the same time during the manufacturing and installation process of the column and the supporting column, there is no need to subsequently add damper fixing devices and equipment, which improves the economy and reliability of the column and the supporting column; the above scheme solves the problems of the existing steel structure swing column being easily affected by wind during the installation process, resulting in poor stability and high axial stiffness and easy breakage.
