Multidirectional displacement limiting device

Abstract

The utility model provides a multidirectional displacement limiting device which comprises an upper disc and a lower disc, the upper disc comprises an upper disc cover and a limiting outer disc, the upper disc cover is fixedly connected with an upper building, and the limiting outer disc is arranged below the upper disc cover; the lower disc comprises a limiting inner disc and a lower disc bottom support, the limiting inner disc is arranged above the lower disc bottom support, the limiting inner disc and the limiting outer disc are mutually nested, a gap is formed between the limiting inner disc and the limiting outer disc, and the lower bottom support is connected with an external base. Through the combination of the upper disc and the lower disc, under accidental working conditions, before the relative deformation between an upper building and the base is about to exceed the allowable deformation of a vibration isolation device or other deformable supports for connecting the upper building and the base, the structure plays a role in limiting protection, so that the normal work of the vibration isolation device or other deformable supports is ensured; meanwhile, it is guaranteed that the building above does not displace or overturn by a large margin. Under the normal use state of the vibration isolation device or other deformable supports, the upper disc and the lower disc move independently through the gap between the upper disc and the lower disc, and the limiting device is not triggered to work.

Description

Technical Field

[0001] The utility model relates to the field of architectural design, in particular to a multi-directional displacement limiting device. Background Art

[0002] Maintaining the building's earthquake resistance while isolating vibrations is a problem that must be solved for buildings that use vibration isolation design. How to design a device that can play a role in limiting protection before the vibration isolation device or other deformable supports reach their normal working limit capacity, while ensuring that the building does not experience large displacement or overturning, is a problem that the existing technology needs to solve. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a multi-directional displacement limiting device, which can provide directional displacement or overturning limitation for a building under accidental working conditions before some vibration isolation devices reach their normal working limit capacity, while preventing the building from excessive deformation or even collapse.

[0004] In order to solve the above problems, the utility model provides a multi-directional displacement limiting device, including an upper plate and a lower plate: the upper plate includes an upper plate cover and a limiting outer plate, the upper plate cover is fixedly connected to the upper building, and the limiting outer plate is arranged below the upper plate cover; the lower plate includes a limiting inner plate and a lower plate base, the limiting inner plate is arranged above the lower plate base, and the limiting inner plate and the limiting outer plate are nested with each other and have a gap, and the lower base is connected to the external base.

[0005] Optionally, the base includes a chassis, embedded sleeves and steel bars, and shear keys.

[0006] Optionally, the base is a leveling base.

[0007] Optionally, the contact surface between the position-limiting outer disk and the position-limiting inner disk, and the contact surface between the position-limiting inner disk and the upper disk cover include a flexible buffer material layer.

[0008] The utility model realizes that under accidental working conditions, when the relative deformation between the upper building and the base is about to exceed the allowable deformation of the vibration isolation device or other deformable support connecting the two, the above structure plays a role of limiting protection, ensuring the normal operation of the vibration isolation device or other deformable support, and at the same time ensuring that the upper building does not have excessive displacement or overturning. In the normal use state of the vibration isolation device or other deformable support, the gap between the upper and lower plates allows the upper and lower plates to move independently of each other, without triggering the limit device to work.

[0010] Attached Figure 2 Shown is a schematic diagram of the assembly structure of a multi-directional displacement limiting device according to a specific implementation manner of the utility model. DETAILED DESCRIPTION

[0011] The specific implementation of the multi-directional displacement limiting device of the utility model is described in detail below with reference to the accompanying drawings.

[0012] Attached Figure 1 FIG. 1 is a schematic diagram of the exploded structure of a multi-directional displacement limiting device according to a specific embodiment of the present invention. Figure 2 Shown is a schematic diagram of the assembly structure of a multi-directional displacement limiting device according to a specific implementation manner of the utility model.

[0013] In this specific embodiment, the upper plate 1 includes an upper plate cover 11 and a limiting outer plate 12. The upper plate cover 11 is fixedly connected to the upper building. The limiting outer plate 12 is arranged below the upper plate cover 11. The lower plate 2 includes a limiting inner plate 23 and a lower plate bottom support 24, the limiting inner plate 23 is arranged above the lower plate bottom support 24, and the limiting inner plate 23 and the limiting outer plate 12 are mutually nested and have a gap, and the lower bottom support 24 is connected to the external base 3. The base 3 includes a chassis 35, and preferably includes an embedded sleeve and a steel bar 36 and a shear key 37.

[0014] Specifically, the upper plate cover 11 can be combined with the building, and the limiting outer plate 12 can be directly connected to the building. The lower plate 2 includes a limiting inner plate 23 and a lower plate base 24. The limiting inner plate 23 is arranged on the surface of the lower plate base 24. The limiting inner plate 23 needs to be nested with the limiting outer plate 12 up and down and determine the reserved distance, and then temporarily fixed relatively with angle steel or other methods.

[0015] The base 3 includes a chassis 35, an embedded sleeve and a steel bar 36 and a shear key 37. The base is a leveling base. After the upper plate 1 and the lower plate 2 are fixed together, the height of the chassis 35 is adjusted so that it contacts the lower plate base 24 for easy connection. The shear key 37 is placed in the center of the chassis 35 and is processed together with the chassis 35. A certain gap is reserved between the base 3 and the lower concrete conversion structure, and the bottom is grouted densely after the adjustment is completed. The above structure realizes that under accidental working conditions, when the relative deformation between the upper building and the base is about to exceed the allowable deformation of the vibration isolation device or other deformable support connecting the two, the above structure plays a role of limiting protection, ensuring the normal operation of the vibration isolation device or other deformable support, and at the same time ensuring that the upper building does not have excessive displacement or overturning. Under normal use of the vibration isolation device or other deformable support, the gap between the upper and lower plates allows the upper and lower plates to move independently of each other without triggering the limit device to work.

[0016] Further, as attached Figure 2As shown, the gap between the limiting outer plate 12 and the limiting inner plate 23 includes a flexible buffer material layer 7, and the gap between the limiting inner plate 23 and the upper plate cover 11 includes a flexible buffer material layer 8, so as to avoid direct collision between the limiting outer plate 12 and the limiting inner plate 23, and play a buffering role in the working state of all-directional limitation.

[0017] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
