Description

Technical Field

[0001] This application relates to the technical field of building construction, and particularly to a foundation anti-settlement structure. Background Art

[0002] The foundation refers to the soil layer or rock that bears the loads of buildings, machinery and equipment, etc. Foundations are generally divided into two categories: natural foundations and artificial foundations. A foundation that can meet the requirements of a building without artificial treatment is called a natural foundation, and a foundation that needs to be artificially reinforced to meet the requirements of a building is called an artificial foundation. Most of the foundations of existing buildings adopt artificial foundations.

[0003] Foundation settlement refers to the settlement of the foundation surface caused by the compaction of the foundation soil layer under the action of additional stress. Foundation settlement will cause the building to tilt, crack and even become unusable. Most of the existing artificial foundations are provided with anti-settlement structures. The anti-settlement structure is a vertical or inclined foundation member arranged in the soil, and its function is to penetrate the soft soil layer and transfer the load borne by the foundation to a harder, denser or less compressible foundation bearing layer. An existing anti-settlement structure includes multiple groups of foundation piles and a bearing plate. The bearing plate is used to bear the upper foundation, and the foundation piles are used to insert into the soft soil layer, so as to transfer the load borne by the bearing plate to a harder, denser or less compressible foundation bearing layer.

[0004] However, in the actual use process, the conditions of each area of the soil layer under the foundation are different, which easily leads to different degrees of settlement of the bearing plate placed on the soil layer, and then easily leads to uneven settlement of the foundation, causing damage to the buildings on the foundation. Utility Model Content

[0005] In order to avoid uneven settlement of the foundation and improve the safety of buildings, this application provides a foundation anti-settlement structure.

[0006] This application provides a foundation anti-settlement structure, adopting the following technical solutions:

[0007] A foundation anti-settlement structure includes a pile column main body. A bearing plate is arranged at the top end of the pile column main body. A connecting component for connecting two bearing plates together is jointly arranged on adjacent bearing plates. A pressure dispersion component for enhancing the uniform stress bearing of adjacent bearing plates is arranged on the upper layer of the bearing plate. A concrete cushion layer is arranged on the upper layer of the pressure dispersion component.

[0008] By adopting the above technical solutions, the connection components help to connect adjacent bearing plates together, thus contributing to enhancing the integrity of multiple bearing plates, preventing different degrees of settlement of multiple bearing plates, and further helping to avoid uneven settlement of the foundation as much as possible, improving the safety of the building on the foundation; the pressure dispersion components and the concrete cushion help to enhance the uniformity of the force on multiple bearing plates, thus further preventing different degrees of settlement of multiple bearing plates, further blocking the uneven settlement of the foundation, and further improving the safety of the building on the foundation.

[0009] In a specific feasible implementation, the connection components include plug-in plates, telescopic rods, telescopic springs and anti-disengagement blocks. The plug-in plates are arranged on the adjacent side walls of the bearing plates. Plug-in slots are arranged on the side walls of the bearing plates opposite to the plug-in plates.

[0012] By adopting the above technical solutions, inserting the positioning insertion rods into the positioning insertion holes helps to improve the accuracy of the installation position of the bearing plates. The bearing plates help to enhance the uniformity of the force on multiple bearing plates, thus further preventing different degrees of settlement of multiple bearing plates, further blocking the uneven settlement of the foundation, and further improving the safety of the building on the foundation.

[0014] By adopting the above technical solution, after the positioning rod is inserted into the positioning hole, the supporting spring is used to help the anti-slip block rotate, thereby helping the anti-slip block to be engaged in the anti-slip groove, thereby helping to limit the position of the positioning rod and the pressure plate, and helping to improve the stability of the pressure plate after installation.

[0016] By adopting the above technical solution, the use of movable columns helps to drive the anchor rods to extend out of the pile column body and insert into the soil layer, thereby helping to improve the stability of the pile column body in the soil layer and helping to improve the anti-settlement effect of the pile column body.

[0017] In a specific possible implementation scheme, an anti-sinking pier is sleeved on the top of the pile column body, the anti-sinking pier is connected to the bearing plate, the anti-sinking pier is arranged in a step-shaped manner and the outer circle of the anti-sinking pier gradually decreases in the direction away from the bearing plate.

[0018] By adopting the above technical solution, the anti-sinking piers are used to help prevent the sinking of the pile column body and the bearing plate, thereby helping to further improve the anti-sinking effect of the pile column body and the bearing plate.

[0019] In a specific possible implementation manner, one end of the pile body away from the bearing plate is arranged in a conical shape.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] An embodiment of the present application discloses a foundation anti-settlement structure. Referring to Figure 1 and Figure 2 , it includes a plurality of pile column bodies 1, and a bearing plate 2 is fixedly connected to the top end of each pile column body 1. In this embodiment, the bottom end of the pile column body 1 is tapered, the interior of the pile column body 1 is hollow, an active column 14 can be placed in the pile column body 1 in a liftable manner, a plurality of anchoring rods 15 are hinged on the circumferential side wall of the active column 14, a plurality of insertion holes 16 are formed on the side wall of the pile column body 1, and each anchoring rod 15 is correspondingly inserted into an insertion hole 16. A threaded through hole 17 communicating with the interior of the pile column body 1 is formed through the bearing plate 2, and a limiting cover 18 is threadedly connected in the threaded through hole 17.

[0035] Referring to Figure 1 and Figure 2 , after the pile column body 1 is inserted into the soil layer by an operator, the limiting cover 18 is rotated in the threaded through hole 17, so that the limiting cover 18 drives the active column 14 to move downward, so that the active column 14 drives the anchoring rods 15 to extend out of the pile column body 1 and insert into the soil layer while moving downward, thereby helping to improve the stability of the pile column body 1 in the soil layer and helping to improve the anti-settlement effect of the pile column body 1.

[0036] Referring to Figure 1 and Figure 2 , an anti-settlement pier 19 is fixedly sleeved on the outer ring of the top of the pile column body 1, and the anti-settlement pier 19 is fixedly connected to the bottom surface of the bearing plate 2. In this embodiment, the anti-settlement pier 19 is arranged in a stepped shape and the outer ring of the anti-settlement pier 19 gradually decreases in the direction from top to bottom. After the pile column body 1 is inserted into the soil layer, the anti-settlement pier 19 helps to block the downward movement of the pile column body 1 and the bearing plate 2, thereby helping to further improve the anti-settlement effect of the pile column body 1 and the bearing plate 2.

[0037] Referring to Figure 3 and Figure 4 , a connection assembly 3 is arranged between adjacent bearing plates 2. The connection assembly 3 includes a plug-in board 31, a telescopic rod 32, a telescopic spring 33 and an anti-disengagement block 34. The plug-in board 31 is fixedly installed on the adjacent side walls of the bearing plate 2. Plug-in slots 6 are formed on the side walls of the bearing plate 2 opposite to the plug-in board 31. Installation slots 7 are formed on the top surface and the bottom surface of the plug-in board 31. The telescopic rod 32 is vertically fixedly installed in the installation slot 7. The anti-disengagement block 34 is fixedly connected to the telescopic rod 32 and is movably clamped in the installation slot 7. The telescopic spring 33 is sleeved on the outer periphery of the telescopic rod 32, and one end of the telescopic spring 33 abuts against the anti-disengagement block 34, and the other end abuts against the groove wall of the installation slot 7. A clamping slot 8 is formed on the groove wall of the plug-in slot 6.

[0038] Referring to Figure 3 andFigure 4 When installing the bearing plate 2, the operator inserts the insertion plate 31 on one bearing plate 2 into the insertion slot 6 on another bearing plate 2. After complete insertion, the elastic force of the telescopic spring 33 helps drive the anti - detachment block 34 to snap into the internal engagement slot 8, so that two adjacent bearing plates 2 are clamped and fixed together, which helps improve the integrity of multiple bearing plates 2 after installation, helps prevent different degrees of settlement of multiple bearing plates 2, and further helps avoid uneven settlement of the foundation as much as possible, thus improving the safety of the building on the foundation.

[0039] Refer to Figure 5 and Figure 6 As shown in [Figure 5] and [Figure 6], a pressure - dispersing component 4 is provided on multiple bearing plates 2. The pressure - dispersing component 4 includes a bearing plate 41 and positioning insertion rods 42. The bearing plate 41 is placed on multiple bearing plates 2, and the center position of the bearing plate 2 is located at the abutting position of multiple bearing plates 2. The positioning insertion rods 42 are fixedly installed at the four corners of the bottom surface of the bearing plate 41. Positioning insertion holes 9 are provided on the bearing plate 2. A placement groove 10 is provided at the bottom end of the positioning insertion rod 42. An anti - detachment block 11 is hingedly installed in the placement groove 10. A top - support spring 12 is fixedly connected to the anti - detachment block 11. One end of the top - support spring 12 away from the anti - detachment block 11 abuts against the groove wall of the placement groove 10. An anti - detachment groove 13 communicating with the positioning insertion hole 9 is provided in the bearing plate 2.

[0040] Refer to Figure 5 and Figure 6 As shown in [Figure 7] and [Figure 8], after the bearing plate 2 is installed, the operator inserts multiple positioning insertion rods 42 into multiple positioning insertion holes 9 on different bearing plates 2 respectively. After complete insertion, the elastic force of the top - support spring 12 helps drive the anti - detachment block 11 to snap into the anti - detachment groove 13, so that the positioning insertion rod 42 is fixedly clamped with the bearing plate 2, which further helps improve the stability of the relative position between the bearing plate 41 and the bearing plate 2. The bearing plate 41 helps improve the uniformity of the force on multiple bearing plates 2, helps further prevent different degrees of settlement of multiple bearing plates 2, helps further block the uneven settlement of the foundation, and further improves the safety of the building on the foundation.

[0041] Refer to Figure 1 As shown in [Figure 9], a concrete cushion layer 5 is poured on the upper layer of multiple bearing plates 41, and a steel bar framework 20 is placed inside the concrete cushion layer 5. The concrete cushion layer 5 helps improve the uniformity of the force on multiple bearing plates 41, thereby helping to improve the uniformity of the force on multiple bearing plates 2, helping to further prevent different degrees of settlement of multiple bearing plates 2, further blocking the uneven settlement of the foundation, and further improving the safety of the building on the foundation.

[0042] The implementation principle of the embodiments of this application is as follows: After the operator inserts the pile column main body 1 into the soil layer, the operator rotates the limit cover 18 in the threaded through hole 17, so that the limit cover 18 drives the movable column 14 to move downward. Thus, while the movable column 14 moves downward, it drives the anchor rod 15 to extend out of the pile column main body 1 and insert into the soil layer, which helps to improve the stability of the pile column main body 1 in the soil layer and helps to improve the anti-settlement effect of the pile column main body 1.

[0043] When installing the bearing plate 2, the operator inserts the insertion plate 31 on one bearing plate 2 into the insertion slot 6 on another bearing plate 2. When the insertion is complete, the elastic force of the telescopic spring 33 itself helps to drive the anti-disengagement block 34 to snap into the inside of the clamping groove 8, so that two adjacent bearing plates 2 are clamped and fixed together, which helps to improve the integrity of multiple bearing plates 2 after installation, helps to prevent different degrees of settlement of multiple bearing plates 2, and thus helps to avoid uneven settlement of the foundation as much as possible, improving the safety of the building on the foundation.

[0044] After the installation of the bearing plate 2 is completed, the operator inserts multiple positioning insertion rods 42 into multiple positioning insertion holes 9 on different bearing plates 2 respectively. When the insertion is complete, the elastic force of the top support spring 12 itself helps to drive the anti-disengagement block 11 to snap into the inside of the anti-disengagement groove 13, so that the positioning insertion rod 42 is fixedly clamped with the bearing plate 2, which helps to improve the stability of the relative position between the bearing plate 41 and the bearing plate 2. The bearing plate 41 helps to improve the uniformity of the force on multiple bearing plates 2, helps to further prevent different degrees of settlement of multiple bearing plates 2, helps to further prevent uneven settlement of the foundation, and further improves the safety of the building on the foundation.

[0045] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
