Description

Technical Field

[0001] This utility model relates to the field of steel structure buildings, and in particular to a movable support. Background Technology

[0002] With the rapid development of my country's economy and changes in social needs, high-rise building structures are evolving towards higher levels, higher strength, and composite structures. Simultaneously, their architectural design is shifting from single-function applications to comprehensive, multi-purpose uses. The demands for multi-functional use and architectural aesthetics inevitably lead to complex and varied structural forms, particularly in the floor plans and facades of high-rise buildings. In recent years, structural forms with large foundations and multiple steel structures interconnected by connecting corridors and steel beams have become increasingly common.

[0003] In existing technologies, the steel beams of connecting corridors are all lapped onto the supporting platform of the main steel structure and rigidly connected by support connection devices, making them a connected structure. If the steel beams of the connecting corridor are subjected to force majeure such as earthquakes or wind loads, the vibration or swaying frequencies of the steel beams and the main steel structure may be different, which can easily cause misalignment and deformation between the steel beams and the two main steel structures. The steel beams of the connecting corridor are difficult to coordinate the deformation between the two main steel structures, which can easily cause the connecting corridor to detach from the main steel structure and cause safety accidents. Utility Model Content

[0004] The purpose of this invention is to provide a movable support to solve the problems existing in the prior art.

[0005] The purpose of this utility model is achieved as follows: A movable support, from top to bottom, includes an upper connecting seat, an upper sliding seat, a spherical liner, a lower sliding seat, and a lower connecting seat. A first planar sliding plate is provided between the upper connecting seat and the upper sliding seat. The upper surface of the spherical liner is horizontal, and the lower surface is spherical. A second planar sliding plate is provided between the upper sliding seat and the spherical liner, a spherical sliding plate is provided between the spherical liner and the lower sliding seat, and a third planar sliding plate is provided between the lower sliding seat and the lower connecting seat. This movable support, through the relative sliding between the upper connecting seat and the upper sliding seat, the relative sliding between the lower sliding seat and the lower connecting seat, and the rotation of the spherical liner, can accommodate horizontal displacement of the upper structure of the connecting corridor steel beam caused by factors such as temperature changes, earthquakes, or strong winds, ensuring the connection stability of the connecting corridor steel beam and guaranteeing the safety of the steel structure building.

[0006] As a further improvement of this utility model, the first planar sliding plate is installed on the upper end of the upper sliding seat, and the lower surface of the upper connecting seat is provided with a first stainless steel plate that cooperates with the first planar sliding plate. The second planar sliding plate is installed on the upper end of the spherical liner, and the lower surface of the upper sliding seat is provided with a second stainless steel plate that cooperates with the second planar sliding plate. The third planar sliding plate is installed on the lower end of the lower sliding seat, and the upper surface of the lower connecting seat is provided with a third stainless steel plate that cooperates with the third planar sliding plate. The spherical sliding plate is installed on the lower end of the lower sliding seat to ensure smooth horizontal sliding and rotation.

[0007] As a further improvement of this utility model, the first stainless steel plate and the third planar sliding plate are rectangular, and the long side of the first stainless steel plate and the third planar sliding plate are perpendicular to each other, so that the movable support has a two-way sliding function in both front and back and left and right.

[0008] As a further improvement of this utility model, the second planar sliding plate and the second stainless steel plate are circular, and the area of ​​the second stainless steel plate is slightly larger than that of the second planar sliding plate, ensuring smooth rotation and further improving the environmental adaptability of the support.

[0009] As a further improvement of this utility model, a first stepped mating structure is provided between the outer side of the upper sliding seat and the upper connecting seat in the width direction, and upper sliding limiting plates are provided on both sides of the upper connecting seat in the length direction, which improves the overall integrity of the movable support, resists earthquakes and prevents detachment, thereby ensuring the structural stability and safety of the movable support in use.

[0010] As a further improvement of this utility model, a second stepped mating structure is provided between the inner side of the upper sliding seat and the outer side of the lower sliding seat, which further improves the seismic resistance and anti-dislodgement performance of the movable support.

[0011] As a further improvement of this utility model, a third stepped mating structure is provided between the outer side of the sliding support and the width direction of the lower connecting seat, and sliding limit plates are provided on both sides of the length direction of the lower connecting seat, which further improves the structural stability and safety of the movable support.

Detailed Implementation

[0015] like Figure 1-2 The movable support shown includes, from top to bottom, an upper connecting seat 1, an upper sliding seat 2, a spherical liner 3, a lower sliding seat 4, and a lower connecting seat 5. A first planar sliding plate 6 is provided between the upper connecting seat 1 and the upper sliding seat 2.

The spherical sliding plate 8 is installed on the lower end of the lower sliding seat. The lower surface of the spherical liner 3 is electroplated with a hard finish to ensure smooth horizontal sliding and rotation. The first stainless steel plate 10 and the third flat sliding plate 9 are rectangular, and their long sides are perpendicular, thus enabling the movable support to slide in both forward and backward, and left and right directions.
