Description

A kind of bearing and its working method of adaptive uneven settlement of foundation
Technical field
The present invention relates to a kind of frame structures, and in particular to a kind of bearing and its working method for frame structure.
Background technology
The building of frame structure be widely used in China it is general, but pure frame structure resist ground inhomogeneous deformation property Can be poor, differential settlement can cause the beam column of frame structure to generate larger additional internal force and additional deformation.Therefore, China 《Code for design of building》(GB50007-2011)Section 5.3, to structure foundation deformation permissible value give related limit System, wherein 5.3.3 items provide that frame structure and single row frame structure structure should be controlled by the differential settlement of adjacent base for post, and then limit Frame structure building is applied to the ground for having differential settlement.
It is on the one hand at present that differential settlement ground is avoided from building arrangements for the measure of differential settlement is reduced, separately On the one hand it is to take the rigidity for increasing basis in structure, such as increases beam cross-section, setting foundation beam etc..But both measures are all It is to reduce differential settlement using " hard anti-" as the measure of dominant ideas, although certain effect can be played, its structure is multiple Miscellaneous, assembly and disassembly are not easy, and have increased considerably the cost of building.
Invention content
Goal of the invention:It is an object of the invention to propose simple in structure, the convenient for disassembly and assembly, low engineering cost of one kind and resist The bearing and its working method of pressure, bending resistance and the higher adaptive uneven settlement of foundation of shear-carrying capacity.
Technical solution:The present invention provides a kind of bearing of adaptive uneven settlement of foundation, bearing is arranged in frame column Between foot and rigid foundation, including coaxial active pull rod, inner cylinder, outer barrel and spring;The active pull rod is by top plate, chassis Constituted with the vertical pole of connection top plate and center chassis, inner cylinder is sleeved on vertical pole and can freely move up and down, top plate and inner cylinder it Between be equipped in relaxation state spring, between inner cylinder bottom surface and chassis be equipped with prevent relatively rotate occlusion structure;It is described outer Jacket casing is loaded on the part contacted outside inner cylinder and with inner cylinder and is equipped with compatible screw thread.
Further, the outer barrel is equipped with the outer barrel top plate of connection framework suspension column, and the chassis of active pull rod connects rigid foundation.
Further, the outer barrel top plate and active pull rod chassis are equipped with longitudinal perforative screw hole.
Further, the bottom surface of the inner cylinder is equipped with the groove radially diverged, and the upper surface on the active pull rod chassis is set There is the protrusion rib body for being adapted and radially diverging.
Further, the internal diameter of the outer barrel bottom end is identical as the outer diameter of inner cylinder, and the inner wall of bottom part and inner cylinder is outer Wall is equipped with compatible screw thread.
A kind of working method of the bearing of adaptive uneven settlement of foundation drives and lives when rigid foundation settles Dynamic pull rod sinks, and outer barrel is fixed, and inner cylinder is disengaged with active pull rod chassis, and bearing is not subjected to upper frame load;Due to Active pull rod moves down, spring by active pull rod top plate extruding and so that inner cylinder is pressurized, inner cylinder starts along the screw thread of outer barrel It rotates and glides, until inner cylinder bottom surface contacts stopping sliding with active pull rod chassis again, bearing restarts to bear top lotus It carries, the occlusion structure between inner cylinder bottom surface and chassis hinders the rotation of inner cylinder, prevents inner cylinder from being revolved along outer barrel screw thread, final to eliminate Sedimentation.
Advantageous effect:Bearing of the present invention has the ability of adaptive ground inhomogeneous deformation, utilizes the automatic of seat structure Elongation can eliminate differential settlement of the frame structure with ground automatically, effectively reduce shadow of the ground inhomogeneous deformation to frame structure It rings and destroys, sensitivity is higher;In addition the seat structure is simple, can replace maintenance, and resistance to compression, bending resistance and shear resistance at any time It is larger, basis can be provided for the more preferable application of frame structure, there is wide applicability.

Specific implementation mode
Technical solution of the present invention is described in detail below, but protection scope of the present invention is not limited to the implementation Example.
A kind of bearing of adaptive uneven settlement of foundation, as shown in Figure 1, the setting of bearing 2 is in frame suspension column 1 and rigid base Between plinth 3.Including coaxial active pull rod 6, inner cylinder 5, outer barrel 4 and spring 10, as shown in Figure 2.Wherein, active pull rod 6 by Upper and lower horizontally disposed top plate 11 and chassis 8 and the vertical pole 12 at connection top plate 11 and 8 center of chassis are constituted, as shown in Figure 3.It is interior Cylinder 5 is sleeved on vertical pole 12 and can freely move up and down, and the outer wall of inner cylinder 5 is covered with screw thread, as shown in Figure 4.The top of active pull rod 6 The spring 10 in relaxation state, the chassis 8 of 5 bottom surface of inner cylinder and active pull rod 6 are equipped between 5 top surface of 11 lower surface of disk and inner cylinder Between be equipped with the occlusion structure for preventing relatively rotating, specifically, the bottom surface of inner cylinder 5 is equipped with the groove that radially diverges, such as Fig. 5, The upper surface on 6 chassis 8 of active pull rod, which is equipped with, is adapted the protrusion rib body radially diverged, and prominent rib body can be embedded in groove.Outside Cylinder 4 is sleeved on outside from the top of inner cylinder 5, and 4 upper inner diameter of outer barrel is more than the outer diameter of inner cylinder 5, therefore the top plate 11 of active pull rod 6 It is contracted in inside outer barrel 4.The internal diameter of 4 bottom of outer barrel is identical as the outer diameter of inner cylinder 5, and the inner wall of bottom is equipped with outer with inner cylinder 5 The compatible screw thread of wall ensures that inner cylinder 5 can automatically glide along the screw thread of outer barrel 4 under the effect of gravity, as shown in Figure 6.
The top of the present embodiment outer barrel 4 is equipped with outer barrel top plate 7, and outer barrel top plate 7 and 6 chassis 8 of active pull rod open up longitudinal direction Perforative screw hole 9 is respectively used to the rigid foundation 3 of the frame suspension column 1 and lower section of connection top.
In use, when rigid foundation 3 settles, under driving active pull rod 6 rapid by the chassis 8 of active pull rod 6 Heavy, outer barrel 4 is temporarily motionless due to being fixed with frame suspension column 1, and 5 bottom of inner cylinder is disengaged with 6 chassis 8 of active pull rod at this time, and bearing 2 is not Upper frame load is born again;Due to moving down for active pull rod 6, spring 10 by 6 top plate of active pull rod extruding and make inner cylinder 5 It is pressurized, under the action of dead weight and spring 10, inner cylinder 5 starts to rotate and glide along the screw thread of outer barrel 4, until 5 bottom of inner cylinder Face contacts stopping sliding with 6 chassis 8 of active pull rod again, and the groove of 5 bottom surface of inner cylinder and the protrusion rib body of 8 upper surface of chassis are mutual Occlusion, bearing 2 restarts to bear upper load, and the rotation of inner cylinder 5 is hindered by occlusion structure, prevents inner cylinder 5 along 4 spiral shell of outer barrel Line generates the trend of upward precession, and then achievees the purpose that making up basis automatically settles.
