Description

Technical Field

[0001] This utility model relates to the field of foundation reinforcement technology for old buildings, specifically to a column-supported independent foundation reinforcement structure. Background Technology

[0002] With the continuous development of society, the reinforcement and renovation of old buildings has become an important issue facing the construction industry. Damage to the foundation or increase in structural load often leads to the original foundation size and reinforcement not meeting the stress requirements, requiring reinforcement in order to improve the bearing capacity of the foundation.

[0003] Existing technology CN208183812U describes a seismic reinforcement structure for column foundations, comprising an original concrete pad, an original column foundation, an enlarged foundation portion, vertical rebar, and horizontal rebar. The original column foundation is constructed on the original concrete pad. The original column foundation is a cylindrical independent foundation with a frustum structure at its base. The enlarged foundation portion is a reinforced foundation portion extending outward from the original concrete pad and the original column foundation. The vertical rebar is installed on the top surface of the frustum at the bottom of the original column foundation, connecting the original column foundation and the enlarged foundation portion. The horizontal rebar is a U-shaped rebar, with one end connecting the original column foundation and the original concrete pad, and the other end extending upward along the frustum surface of the enlarged foundation portion. This structure can improve the shear strength of the foundation, meet the seismic requirements of the added building, and thus improve the structural performance.

[0004] Under normal use, existing technologies involve a large amount of work in concrete excavation, steel bar welding, and rebar installation during construction, requiring a significant amount of time and cost. When the area of ​​the bottom reinforcement required by the foundation calculation increases, it is impossible to increase the original foundation bottom reinforcement, which poses certain safety hazards and affects the reinforcement effect of the foundation. Summary of the Invention

[0005] The purpose of this utility model is to provide a column-supported independent foundation reinforcement structure to solve the problems of existing technologies, which involve a large amount of work in concrete excavation, steel bar welding and rebar installation during construction, requiring a long construction period and high cost; and the inability to increase the original foundation rebar area when the required bottom rebar area increases, which poses certain safety hazards.

[0006] To achieve the above objectives, this utility model provides a column-supported independent foundation reinforcement structure, including the original column foundation and structural components. The structural components include a column, plain concrete, a new foundation, base reinforcement, and shear reinforcement. The plain concrete wraps around the outside of the original column foundation. The column is fixedly connected to the original column foundation and located above it. The new foundation is placed above the plain concrete and the original column foundation. The base reinforcement is fixedly installed at the bottom of the new foundation. The shear reinforcement is fixedly connected to the column and also fixedly connected to the new foundation.

[0007] The column has a connecting hole located at the junction of the column and the new foundation, and it engages with the shear reinforcement.

[0008] The column has a through hole located at the bottom of the column and is fitted with the base reinforcement.

[0009] The newly added foundation has a roughened surface, which is located on the side of the newly added foundation closest to the column and cooperates with the column.

[0010] The plain concrete is flush with the top of the original column foundation.

[0011] This utility model provides a column-supported independent foundation reinforcement structure. The new foundation is placed above the original column foundation and the plain concrete. The base reinforcement is laid at the bottom of the new foundation. Within the column width, the base reinforcement is connected to the new foundation through the through hole by rebar anchoring. The shear reinforcement is set at the junction of the new foundation and the column. The shear reinforcement is connected to the new foundation through the connecting hole by rebar anchoring. The plain concrete and the original column foundation together serve as the cushion layer of the new foundation. The new foundation, the base reinforcement, and the shear reinforcement together form a new column-supported independent foundation to bear the load transmitted from the column, thereby improving the foundation reinforcement effect.

[0015] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0016] The first embodiment of this application is as follows:

[0017] Please see Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the column-supported independent foundation reinforcement structure according to the first embodiment of this utility model. This utility model provides a column-supported independent foundation reinforcement structure, including the original column foundation 101 and structural components. The structural components include a column body 102, plain concrete 103, a new foundation 104, base reinforcement 105, and shear reinforcement 106. The column body 102 has connecting holes 107 and through holes 108. The new foundation has a roughened surface 109. This solution addresses the problems of existing technologies where the workload of concrete excavation, rebar welding, and rebar installation during construction is large, requiring significant time and cost. Furthermore, when the required area of ​​the bottom reinforcement in the foundation calculation increases, it is impossible to increase the original foundation bottom reinforcement, posing certain safety hazards. It is understood that the aforementioned solution can be used when existing technologies involve large workloads of concrete excavation, rebar welding, and rebar installation during construction, requiring significant time and cost, and when the required area of ​​the bottom reinforcement in the foundation calculation increases, it is impossible to increase the original foundation bottom reinforcement, posing certain safety hazards.

[0018] In this specific embodiment, the new foundation 104 is placed on top of the original column foundation 101 and the plain concrete 103. The base reinforcement 105 is laid at the bottom of the new foundation 104. Within the column width, the base reinforcement 105 penetrates the column 102 by means of rebar anchoring. The shear reinforcement 106 is set at the junction of the new foundation 104 and the column 102, and the shear reinforcement 106 penetrates the column 102 by means of rebar anchoring. The plain concrete 103 and the original column foundation 101 together serve as the cushion layer of the new foundation 104. The new foundation 104, the base reinforcement 105, and the shear reinforcement 106 together form a new independent foundation under the column to bear the load transmitted from the column, thereby improving the reinforcement effect of the foundation.

[0019] The plain concrete 103 surrounds the original column foundation 101. The column 102 is fixedly connected to the original column foundation 101 and located above it. The new foundation 104 is placed above the plain concrete 103 and the original column foundation 101. The base reinforcement 105 is fixedly installed at the bottom of the new foundation 104. The shear reinforcement 106 is fixedly connected to the column 102 and the new foundation 104. Multiple connection holes are designed at the junction of the column 102 and the new foundation 104. Multiple through holes are designed at the bottom of the column 102. The new foundation 104 is located on top of the plain concrete 103. The base reinforcement 105 has... Multiple base reinforcement bars 105 are located at the bottom of the new foundation 104. The base reinforcement bars 105 penetrate the through-hole of the column 102 via rebar anchoring. Multiple shear reinforcement bars 106 are also present, penetrating the connection holes of the column 102 via rebar anchoring. The new foundation 104, together with the base reinforcement bars 105 and the shear reinforcement bars 106, forms a new independent column foundation to bear the load transmitted from the column, thereby improving the foundation reinforcement effect.

[0020] Secondly, the column 102 has a connecting hole 107, which is located at the junction of the column 102 and the new foundation 104 and cooperates with the shear reinforcement 106. There are multiple connecting holes 107. The shear reinforcement 106 passes through the connecting holes 107 and is fixedly connected to the new foundation 104, thereby increasing the connection strength between the column 102 and the new foundation 104 and thus transferring the load borne by the column 102 to the new foundation 104.

[0021] Meanwhile, the column 102 has through holes 108 located at the bottom of the column 102 and cooperating with the base reinforcement 105. There are multiple through holes 108, and the base reinforcement 105 passes through the through holes 108. The base reinforcement 105 passes through the through holes 108 and is fixedly connected to the new foundation 104, thereby increasing the connection strength between the column 102 and the new foundation 104, and thus realizing the connection between the base reinforcement 105, the new foundation 104 and the column 102.

[0022] Then, the new foundation 104 has a roughened surface 109, which is located on the side of the new foundation 104 close to the column 102 and cooperates with the column 102. The connection between the column 102 and the new foundation 104 is further improved by the cooperation between the roughened surface 109 and the column 102.

[0023] Finally, the plain concrete 103 is flush with the top of the original column foundation 101, and the top of the plain concrete 103 and the original column foundation 101 are in contact with the bottom of the new foundation 104. Through the cooperation of the plain concrete 103 and the original column foundation 101, they together serve as the pad layer for the new foundation 104, supporting the new foundation 104, thereby transferring the load borne by the new foundation 104 to the original bearing layer through the plain concrete 103 and the original column foundation 101.

[0024] When using the column-supported independent foundation reinforcement structure of this embodiment, the new foundation 104 is placed above the original column foundation 101 and the plain concrete 103. The base reinforcement 105 is laid at the bottom of the new foundation 104. Within the column width range, the base reinforcement 105 is connected to the new foundation 104 through the through hole 108 by means of rebar anchoring. The shear reinforcement 106 is set at the junction of the new foundation 104 and the column 102. The shear reinforcement 106 is connected to the new foundation 104 through the connection hole 107 by means of rebar anchoring. The plain concrete 103 and the original column foundation 101 together serve as the cushion layer of the new foundation 104. The new foundation 104, the base reinforcement 105, and the shear reinforcement 106 together form a new column-supported independent foundation to bear the load transmitted from the column, thereby improving the reinforcement effect of the foundation.
