[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. The directional words such as "upper" and "lower" involved in this article are all relative to the viewing angle of the accompanying drawings. They are only for the convenience of description and cannot be understood as limitations on the technical solution. The "first, second..." used are only used to distinguish the names and do not represent specific quantities and orders.

[0027] like Figure 1-4 As shown, the utility model provides a device for stone column underpinning, and the device for stone column underpinning includes a device body 1 and a fastener 2. The device body 1 has a cavity for placing the stone column, and the device body 1 is composed of a plurality of plates, and the plurality of plates are detachably connected. Specifically, the number of plates is four, and the length of two of the plates is greater than the length of the remaining two plates. When in use, four reinforced concrete columns or a stable bracket can be cast in advance at the construction site, and the two longer plates can be placed in the concrete column or bracket. The fastener 2 is arranged above or at the bottom of the device body, and the number is two. The two fasteners 2 act on the opposite sides of the stone column respectively. Under the action of the fastener 2, the shaking of the building column 7 can be further restricted. Therefore, through the above-mentioned device for stone column underpinning, it is possible to prevent the building from shaking easily due to the hollowing of the earth around the building column 7, and ensure that the building is not damaged, and the device has the advantages of simple operation, convenience and high efficiency.

[0028] In a specific embodiment, the device for replacing stone columns also includes a guardrail 3, which is connected to the device body 1. The guardrail 3 is composed of multiple railings. The columns 7 of the building are surrounded by guardrails 3. The guardrails 3 can prevent other people or objects from touching the columns 7 of the building. At the same time, during the process of building relocation, the columns 7 of the building are protected to prevent external objects from touching the columns 7 of the building.

[0029] In a specific embodiment, the guardrail 3 is provided with a support rod 4. More specifically, the number of the support rods 4 is multiple. The support rods 4 are detachably connected to the guardrail 3 and connected to the guardrail 3 through fasteners. The support rods 4 can be set on the inner side of the bottom of the guardrail 3 or on the outer side of the bottom of the guardrail 3. The specific installation method depends on the actual size of the building. The support rods 4 clamp the columns 7 of the building to play a supporting role, thereby providing an upward supporting force for the building.

[0030] In a specific embodiment, a polystyrene board 5 is provided on the inner side of the device body 1 and the inner side of the fastener 2. The polystyrene board 5 is a polystyrene foam plastic board with a closed-cell structure made by pre-foaming expandable polystyrene beads and then heating and molding them in a mold. The polystyrene board 5 is made of raw materials that have been pre-foamed, matured, molded, dried and cut. It can be made into foam products of different densities and shapes, and can also produce foam boards of various thicknesses. It is widely used in the fields of construction, heat preservation, packaging, freezing, daily necessities, industrial casting, etc. The surface of the polystyrene board 5 is smoother than the surface of the device body and the fastener 2. When in use, it can not only reduce the damage to the column 7 of the building to a certain extent, but also adjust the firmness of the device body, the fastener 2 and the column 7 of the building.

[0031] In a specific embodiment, the polystyrene boards 5 are all provided with outer leather, and the surface of the outer leather is relatively smooth and has good flexibility. During construction, especially when relocating ancient buildings, the polystyrene boards 5 are provided with outer leather, and the outer leather contacts the columns 7 of the building, which can effectively reduce the damage to the columns 7 of the building.

[0032] In a specific embodiment, both the device body 1 and the fastener 2 are provided with bolts 6. More specifically, the ends of the bolts 6 are connected to the polystyrene board 5. By adjusting the bolts 6, the tightness of the device body 1 and the fastener 2 on the building column 7 can be adjusted.

[0033] In a specific embodiment, the device body 1 , the fastener 2 and the guardrail 3 are all made of metal materials. More specifically, the metal material is preferably stainless steel, so as to ensure the durability of the device body 1 , the fastener 2 and the guardrail 3 .

[0034] The use principle of the utility model is as follows: the device body 1 is composed of four plates, which are detachably connected. The length of two plates is greater than that of the other two plates. When in use, four reinforced concrete columns or stable brackets can be cast in advance at the construction site, and the two longer plates can be placed in the concrete columns or brackets. The fasteners 2 are arranged above or at the bottom of the device body, and there are two of them. The two fasteners 2 act on the opposite sides of the stone column respectively. Under the action of the fasteners 2, the shaking of the building column 7 can be further restricted, thereby preventing the building from shaking easily due to the hollowing of the earth around the building column 7, ensuring that the building is not damaged, and the device has the advantages of simple operation, convenience and high efficiency. The guardrail 3 is connected to the device body 1, and the guardrail 3 can prevent others or objects from touching the building column 7. At the same time, during the process of building migration, the building column 7 is protected to prevent external objects from touching the building column 7. The guardrail 3 is provided with a plurality of support rods 4. More specifically, the number of support rods 4 is plural. The support rods 4 are connected to the guardrail 3 through fasteners. The support rods 4 can be arranged on the inner side of the bottom of the guardrail 3. The support rods 4 clamp the column 7 of the building, thereby playing a supporting role and never providing an upward support force for the building. The inner side of the device body 1 and the inner side of the fastener 2 are both provided with a polystyrene board 5. The polystyrene board 5 is provided with an outer leather. When the ancient building is moved, the outer leather contacts the column 7 of the building, which can effectively reduce the damage to the column 7 of the building. The device body 1 and the fastener 2 are both provided with a bolt 6. The end of the bolt 6 is connected to the polystyrene board 5. By adjusting the bolt 6, the tightness of the device body 1 and the fastener 2 on the column 7 of the building can be adjusted.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention are still within the scope of the technical solution of the present invention.
