Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building foundation anti-settling device. Background Art

[0002] Foundation settlement refers to the sinking of the foundation surface caused by the compaction of the foundation soil under additional stress. Excessive settlement, especially uneven settlement, can cause a building to tilt, crack, and become unusable.

[0003] At present, when solving the problem of foundation settlement, column piles are used for support. However, the contact area between the existing column piles and the ground is small, resulting in a relatively concentrated pressure on the foundation, which easily causes foundation settlement. Moreover, the column piles do not have a buffering performance and cannot provide good buffering when encountering an earthquake, causing the foundation to easily settle due to excessive instantaneous impact force. Therefore, in view of the above situation, it is urgent to develop a building foundation anti-settlement device that is convenient for dispersing pressure and has good buffering properties, thereby improving the stability of the foundation and preventing the foundation from settling, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the utility model is to provide a building foundation anti-settling device to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A building foundation anti-settlement device includes a soil layer, a concrete support layer, pillars, a base plate, a support ring, a sharing mechanism and a buffer mechanism. A concrete support layer is provided on the top of the soil layer, a plurality of pillars are installed in the soil layer, a buffer mechanism is fixed to the top of the pillar, and the buffer mechanism supports the concrete support layer. A base plate is fixed to the bottom of the pillar, and a plurality of support rings are fixed on the pillar, and a sharing mechanism is provided on the upper side of each support ring.

[0007] Preferably, the plurality of sharing mechanisms are staggered with each other.

[0008] Preferably, the load-sharing mechanism comprises a rotating sleeve and an auxiliary support plate. The rotating sleeve is rotatably connected to the pillar, and two auxiliary support plates are fixed on the rotating sleeve.

[0009] Preferably: the buffer mechanism includes: an outer shell, a support, a spring, a rubber support column and a damper, the outer shell is fixed to the top of the pillar, the outer shell is equipped with a support extending to the outside thereof, the support is fixed to the concrete support layer, the outer shell is equipped with a plurality of springs and rubber support columns fixed to the support, and the outer shell is equipped with a damper connected to the support.

[0010] Preferably, the support is slidably connected to the outer shell.

[0011] The beneficial effects of the present utility model are as follows: the building foundation anti-settlement device increases the contact area between the support and the soil layer through the bottom plate, reduces the concentration of pressure, increases the contact area with the soil layer through multiple sharing mechanisms, disperses the pressure to different positions inside the soil layer, and then reduces the concentration of pressure, thereby reducing the settlement of the soil layer. When the building is subjected to an external impact (such as an earthquake), the impact is transmitted to the support, and the support drives the spring and rubber support column to produce deformation for buffering. At the same time, the impact force is absorbed and converted by the damper, thereby reducing the instantaneous impact on the soil layer, thereby reducing the settlement of the soil layer due to excessive instantaneous impact force. In summary, the present utility model is convenient for dispersing pressure and has good buffering properties, thereby improving the stability of the foundation and preventing foundation settlement.

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Specific examples are given below.

[0020] See also Figures 1 to 4In an embodiment of the present invention, a building foundation anti-settlement device includes a soil layer 1, a concrete support layer 2, pillars 3, a bottom plate 4, a support ring 5, a sharing mechanism 6 and a buffer mechanism 7. A concrete support layer 2 is provided on the top of the soil layer 1, and a plurality of pillars 3 are installed in the soil layer 1. A buffer mechanism 7 is fixed to the top of the pillar 3, and the buffer mechanism 7 supports the concrete support layer 2. A bottom plate 4 is fixed to the bottom of the pillar 3. The bottom plate 4 increases the contact area between the pillar 3 and the soil layer 1 and reduces the concentration of pressure. A plurality of support rings 5 ​​are fixed on the pillar 3, and a sharing mechanism 6 is provided on the upper side of each support ring 5. The plurality of sharing mechanisms 6 are staggered with each other. The plurality of sharing mechanisms 6 disperse the pressure to different positions inside the soil layer 1, thereby reducing the concentration of pressure and reducing the settlement of the soil layer 1. In addition, the buffer mechanism 7 can reduce the external impact (such as earthquake) on the building, thereby reducing the instantaneous impact force on the soil layer 1, thereby reducing the settlement of the soil layer 1 due to excessive instantaneous impact force.

[0021] The sharing mechanism 6 includes: a rotating sleeve 601 and an auxiliary support plate 602. The rotating sleeve 601 is rotatably connected to the pillar 3. Two auxiliary support plates 602 are fixed on the rotating sleeve 601. When in use, the auxiliary support plates 602 disperse the pressure exerted on the pillar 3 to different positions in the soil layer 1.

[0022] The buffer mechanism 7 includes: an outer shell 701, a support 702, a spring 703, a rubber support column 704 and a damper 705. The outer shell 701 is fixed to the top of the pillar 3. A support 702 extending to the outside of the outer shell 701 is installed in the outer shell 701. The support 702 is slidably connected to the outer shell 701 so that the support 702 can move up and down. The support 702 is fixed to the concrete support layer 2. A plurality of springs 703 and rubber support columns 704 fixed to the support 702 are fixed in the outer shell 701. A damper 705 connected to the support 702 is installed in the outer shell 701. When the building is impacted, the impact is transmitted to the support 702, and the support 702 drives the spring 703 and the rubber support column 704 to deform for buffering. At the same time, the damper 705 absorbs and transforms the impact force, thereby reducing the instantaneous impact on the soil layer 1.

[0023] Working principle: The building foundation anti-settlement device increases the contact area between the support 3 and the soil layer 1 through the base plate 4, reduces the concentration of pressure, increases the contact area with the soil layer 1 through multiple sharing mechanisms 6, and disperses the pressure to different positions inside the soil layer 1, thereby reducing the concentration of pressure and reducing the settlement of the soil layer 1. When the building is subjected to external impact (such as an earthquake), the impact is transmitted to the support 702, and the support 702 drives the spring 703 and the rubber support column 704 to deform for buffering. At the same time, the impact force is absorbed and converted by the damper 705, thereby reducing the instantaneous impact on the soil layer 1, thereby reducing the settlement of the soil layer 1 due to excessive instantaneous impact force.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
