Description

Movable support Technical Field The utility model relates to the field of steel structure buildings, in particular to a movable support. Background Along with the high-speed development of the economy and the change of the social demands of China, the building design of the high-rise building structure is developed from single-function application to comprehensive multipurpose while the high-rise building structure is developed towards high-level, high-strength, combined structure and the like. The use of multiple functions and the aesthetic requirements of buildings necessarily lead to complex variability in the structural body and form, especially in the planar and elevational body forms of high-rise buildings. In recent years, a plurality of steel structural bodies of a large chassis are connected with each other by a corridor steel girder in an increasing number of structural forms. In the prior art, the corridor steel beams are all lapped on a bearing table of a steel structure main body structure and are rigidly connected through a support connecting device, so that the corridor steel beams become a conjoined structure. If the corridor steel beam receives an nonresistance force such as an earthquake or a wind load, the vibration or swinging frequencies of the corridor steel beam and the steel structure main bodies may be different, the corridor steel beam and the two steel structure main bodies are easy to generate dislocation and deformation, the corridor steel beam is difficult to coordinate the deformation between the two steel structure main bodies, the corridor is easy to fall off from the steel structure main bodies, and safety accidents are caused. Disclosure of utility model The utility model aims to provide a movable support, which solves the problems existing in the prior art. The movable support comprises an upper connecting seat, an upper sliding seat, a spherical lining plate, a lower sliding seat and a lower connecting seat from top to bottom in sequence, wherein a first plane sliding plate is arranged between the upper connecting seat and the upper sliding seat, the upper surface of the spherical lining plate is horizontal, the lower surface of the spherical lining plate is spherical, a second plane sliding plate is arranged between the upper sliding seat and the spherical lining plate, a spherical sliding plate is arranged between the spherical lining plate and the lower sliding seat, and a third plane sliding plate is arranged between the lower sliding seat and the lower connecting seat. According to the movable support, through the relative sliding of the upper connecting seat and the upper sliding seat, the relative sliding of the lower sliding seat and the lower connecting seat and the rotation of the spherical lining plate, the movable support can adapt to the horizontal displacement of the upper structure of the corridor steel beam caused by factors such as temperature change, earthquake or strong wind influence, and the like, the connection stability of the corridor steel beam is ensured, and the use safety of the steel structure building is ensured. As a further improvement of the utility model, the first planar sliding plate is arranged at the upper end of the upper sliding seat, the lower surface of the upper connecting seat is provided with a first stainless steel plate matched with the first planar sliding plate, the second planar sliding plate is arranged at the upper end of the spherical lining plate, the lower surface of the upper sliding seat is provided with a second stainless steel plate matched with the second planar sliding plate, the third planar sliding plate is arranged at the lower end of the lower sliding seat, the upper surface of the lower connecting seat is provided with a third stainless steel plate matched with the third planar sliding plate, and the spherical sliding plate is arranged at the lower end of the lower sliding seat, so that the smoothness of horizontal sliding and rotation is ensured.
