Description
Technical Field
[0001] The present application relates to the technical field of construction engineering, and in particular to a brick column reinforcement structure. Background Art
[0002] At present, in the construction process of local structural reinforcement of masonry houses, new brick columns are usually built directly around the original building, or tools are added to provide support functions for the original brick columns.
[0003] However, there are disadvantages when using this method for construction: there is a lack of stable force-bearing connection between the new brick columns and the original brick columns, which results in the load borne by the new brick columns cannot be effectively transferred to the original brick columns and further dispersed to the building foundation, which in turn leads to uneven force at the roots of the new brick columns, excessive bearing pressure, and even potential safety hazards such as cracking. These problems seriously affect the stability and safety of the newly added floors; similarly, the newly added tools will increase the difficulty and cost of construction, which does not meet construction needs. Summary of the invention
[0004] In order to effectively improve the consolidation degree of the original brick column at a low cost and ensure safety in use, the present application provides a brick column reinforcement structure.
[0005] The present application provides a brick column reinforcement structure, which adopts the following technical solution:
[0006] A brick column reinforcement structure comprises a brick column, longitudinal reinforcement, horizontal stirrups and a concrete layer, wherein the brick column is assembled on a wall, the longitudinal reinforcement is vertically fixed to the periphery of the brick column, the horizontal stirrups are perpendicular to the longitudinal reinforcement and fixed to the outside of the longitudinal reinforcement, and the concrete layer completely covers the portion where the longitudinal reinforcement and the horizontal stirrups are provided.
[0007] By adopting the above technical solution, brick columns, longitudinal reinforcements, horizontal stirrups and concrete layers are integrated to form a stable brick column reinforcement solution. In this application, the brick column serves as the main structure, and the longitudinal reinforcements fixed vertically on the periphery thereof help to enhance the longitudinal bearing capacity of the brick column to prevent the brick column from being excessively deformed or damaged when subjected to vertical pressure. At the same time, the horizontal stirrups are arranged perpendicular to the longitudinal reinforcements and fixed on the outside of the longitudinal reinforcements, which not only improves the shear resistance of the brick column, but also effectively restrains the expansion of the brick column in the horizontal direction, thereby maintaining the stability of the overall structure. Moreover, the portion where the longitudinal reinforcements and horizontal stirrups are provided is completely covered by the concrete layer, which further enhances the integrity and durability of the structure and ensures the long-term effectiveness of the reinforcement effect. Compared with the prior art, this application does not require the additional laying of new bricks, nor does it require the addition of additional tools to provide support functions, making the entire construction process more efficient and less costly, meeting construction requirements.
[0008] Preferably, there are multiple longitudinal reinforcements, and the multiple horizontal stirrups are evenly distributed on the outer peripheral wall of the brick column.
[0009] By adopting the above technical solution, the arrangement of multiple longitudinal reinforcements increases the contact area between the horizontal stirrups and the brick columns, making the stress distribution more uniform and reducing the occurrence of stress concentration to a certain extent. At the same time, under the action of the horizontal stirrups, the restraining effect of the longitudinal reinforcement on the brick columns can be improved to prevent the brick columns from producing excessive deformation during the force process, thereby ensuring the stability and reliability of the overall structure and improving the bearing capacity and stability of the reinforced structure.
[0010] Preferably, there are a plurality of horizontal stirrups, and the horizontal stirrups are horizontal closed stirrups, and each of the horizontal stirrups is simultaneously fixed to a plurality of the longitudinal reinforcements on the same horizontal plane.
[0011] By adopting the above technical solution, horizontal closed stirrups are used, and each horizontal stirrup is fixed to multiple longitudinal reinforcements on the same horizontal plane at the same time, forming a stable steel skeleton. On the one hand, it can enhance the connection strength between the horizontal stirrups and the longitudinal reinforcements, and on the other hand, it can improve the lateral displacement resistance of the overall structure.
[0012] Preferably, the concrete layer is a high ductility concrete layer.
[0013] By adopting the above technical solution, high-ductility concrete has higher toughness and deformation capacity. When subjected to external force, it can absorb more energy and produce larger deformation without being easily damaged, so that the reinforced brick columns have better seismic performance in extreme conditions such as earthquakes, and can effectively protect the main structure from damage. At the same time, high-ductility concrete also has excellent durability, and can maintain the stability and bearing capacity of the structure for a long time without being affected by environmental factors, thereby achieving the purpose of improving the seismic resistance and durability of the structure.
[0014] Preferably, the filling depth of the concrete layer is not less than 50 mm.
[0015] By adopting the above technical solution, a concrete layer with a filling depth of not less than 50 mm can effectively wrap the longitudinal reinforcement and horizontal stirrups outside the brick column, enhance the integrity and bearing capacity of the structure. At the same time, sufficient concrete layer thickness can also prevent structural damage caused by external factors and improve the durability and safety of the brick column reinforcement structure.
[0016] Preferably, the spacing between two adjacent horizontal stirrups is 100 mm.
[0017] By adopting the above technical solution, a spacing of 100mm can ensure structural strength while taking into account economy and construction efficiency. Such a spacing design not only ensures the density of horizontal stirrups to provide sufficient restraint force, but also reduces material waste and increased construction difficulty caused by excessive density.
[0018] Preferably, within a range of 500 mm from the top or bottom of the brick column, the spacing between two adjacent horizontal stirrups is 100 mm.
[0019] By adopting the above technical solution, the shear bearing capacity and seismic performance of these areas are significantly improved by reducing the spacing of horizontal stirrups to 100mm within the two 500mm intervals.
[0020] Preferably, outside the range of 500 mm at the top or bottom of the brick column, the spacing between two adjacent horizontal stirrups is 200 mm.
[0021] By adopting the above technical solution, this technical feature adjusts the spacing between two adjacent horizontal stirrups to 200mm outside the 500mm range between the top and bottom of the brick column.
[0022] Preferably, the horizontal stirrups pass through the wall.
[0023] By adopting the above technical solution, the horizontal stirrups passing through the wall can enhance the integrity between the brick column and the wall, and prevent relative slippage or separation during the stress process.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. Compared with the prior art, this application does not require the laying of new bricks or the addition of additional tools to provide support functions, making the entire construction process more efficient and less costly, meeting construction requirements;
[0026] 2. High ductility concrete has high toughness and deformation capacity. When subjected to external force, it can absorb more energy and produce larger deformation without being easily damaged. The reinforced brick columns have better seismic performance in extreme conditions such as earthquakes, and can effectively protect the main structure from damage. At the same time, high ductility concrete also has excellent durability, which can maintain the stability and bearing capacity of the structure for a long time without being affected by environmental factors, thereby achieving the purpose of improving the seismic performance and durability of the structure.

[0030] The following is combined with Figure 1-2 This application is described in further detail.
[0031] The embodiment of the present application discloses a brick column reinforcement structure.
[0032] Reference Figure 1 A brick column reinforcement structure includes a brick column 1, longitudinal reinforcements 2, horizontal stirrups 3 and a concrete layer 4, wherein the brick column 1 is assembled on a wall 5, the longitudinal reinforcements 2 are vertically fixed to the periphery of the brick column 1, the horizontal stirrups 3 are perpendicular to the longitudinal reinforcements 2, and the horizontal stirrups 3 are fixed to the outside of the longitudinal reinforcements 2, and the concrete layer 4 completely covers the portion where the longitudinal reinforcements 2 and the horizontal stirrups 3 are provided.
[0033] Specifically, there are multiple longitudinal reinforcements 2, and multiple horizontal stirrups 3 are evenly distributed on the outer peripheral wall of the brick column 1. By arranging multiple longitudinal reinforcements 2, the present application can increase the contact area between the horizontal stirrups 3 and the brick column 1, making the stress distribution more uniform, which can reduce the occurrence of stress concentration to a certain extent. At the same time, under the action of the horizontal stirrups 3, the restraining effect of the longitudinal reinforcement 2 on the brick column 1 can be improved to prevent the brick column 1 from producing excessive deformation during the force process, thereby ensuring the stability and reliability of the overall structure and improving the bearing capacity and stability of the reinforced structure.
[0034] More specifically, there are multiple horizontal stirrups 3, which are horizontal closed stirrups. Each horizontal stirrup 3 is fixed to multiple longitudinal reinforcements 2 on the same horizontal plane at the same time to form a stable steel skeleton, so as to enhance the connection strength between the horizontal stirrups 3 and the longitudinal reinforcements 2 and improve the lateral displacement resistance of the overall structure. During the stress process, the horizontal stirrups 3 can effectively restrain the deformation of the longitudinal reinforcement 2 and reduce its excessive bending or twisting, thereby maintaining the stability and bearing capacity of the overall structure.
[0035] Reference Figure 1 The concrete layer 4 is a high-ductility concrete layer 4, and the filling depth of the concrete layer 4 is not less than 50 mm.
[0036] The present application adopts a high-ductility concrete layer 4 because high-ductility concrete has high toughness and deformation capacity. When subjected to external force, it can absorb more energy and produce larger deformation without being easily damaged. As a result, the reinforced brick column 1 has better seismic performance under extreme conditions such as earthquakes, and can effectively protect the main structure from damage. At the same time, high-ductility concrete also has excellent durability, and can maintain the stability and bearing capacity of the structure for a long time without being affected by environmental factors, thereby achieving the purpose of improving the seismic resistance and durability of the structure.
[0037] The concrete layer 4 with a filling depth of not less than 50 mm can effectively wrap the longitudinal reinforcement 2 and horizontal stirrups 3 outside the brick column 1, thereby enhancing the integrity and bearing capacity of the structure. At the same time, a sufficient thickness of the concrete layer 4 can also prevent structural damage caused by external factors, such as impact or erosion, and improve the durability and safety of the reinforced structure of the brick column 1. The present application can provide a solid support and protection by providing a concrete layer 4 with sufficient thickness.
[0038] Reference Figure 1 The present application does not specifically limit the distance between two adjacent horizontal stirrups 3, but requires that the two horizontal stirrups 3 can always maintain balance, and the horizontal stirrups 3 and the longitudinal reinforcement 2 always remain vertical, and the two are fixed by welding.
[0039] In a preferred embodiment, the spacing between two adjacent horizontal stirrups 3 is 100 mm. The spacing of 100 mm can ensure structural strength while taking into account economy and construction efficiency. Such a spacing design not only ensures the density of the horizontal stirrups 3 to provide sufficient restraint force, but also reduces material waste and increased construction difficulty caused by excessive density. The present application achieves uniform reinforcement of the brick column 1 by setting the spacing between two adjacent horizontal stirrups 3 to 100 mm.
[0040] In another preferred embodiment, within a range of 500 mm from the top or bottom of the brick column 1, the spacing between two adjacent horizontal stirrups 3 is 100 mm; outside a range of 500 mm from the top or bottom of the brick column 1, the spacing between two adjacent horizontal stirrups 3 is 200 mm.
[0041] In these two 500mm ranges, by reducing the spacing of the horizontal stirrups 3 to 100mm, the shear bearing capacity and seismic resistance of these areas are significantly improved. Since the top and bottom of the brick column 1 are areas where the force is more concentrated, such a design can effectively improve the safety and stability of the entire brick column 1 reinforcement structure.
[0042] Outside the 500mm range at the top and bottom of the brick column 1, this technical feature adjusts the spacing between two adjacent horizontal stirrups 3 to 200mm. In these non-critical areas, by appropriately increasing the spacing between the horizontal stirrups 3, the material cost and construction complexity can be reduced while maintaining the overall stability of the structure, which not only ensures the safety of the structure, but also achieves the purpose of saving materials and facilitating construction.
[0043] Reference Figure 1 and Figure 2 In this application, no matter the extension direction of the wall 5 is arranged perpendicular to the height direction of the brick column 1, or the extension direction of the wall 5 is arranged in a straight line with the height direction of the brick column 1, the horizontal stirrups 3 pass through the wall 5. The horizontal stirrups 3 passing through the wall 5 can enhance the integrity between the brick column 1 and the wall 5, and prevent relative slippage or separation during the force process. In this application, the horizontal stirrups 3 can pass through the wall 5, thereby forming a more effective connection and reinforcement with the wall 5. It is helpful to improve the bearing capacity of the reinforced structure of the brick column 1 and enhance the seismic performance and durability of the entire building system.
[0044] In the present application, a brick column 1, longitudinal reinforcement 2, horizontal stirrups 3 and concrete layer 4 are integrated to form a stable reinforcement scheme for the brick column 1. In the present application, the brick column 1 serves as the main structure, and the longitudinal reinforcement 2 fixed vertically on the periphery thereof helps to enhance the longitudinal bearing capacity of the brick column 1 to prevent the brick column 1 from excessive deformation or damage when subjected to vertical pressure. At the same time, the horizontal stirrups 3 are arranged perpendicular to the longitudinal reinforcement 2 and fixed on the outside of the longitudinal reinforcement 2, which not only improves the shear resistance of the brick column 1, but also effectively restrains the expansion of the brick column 1 in the horizontal direction, thereby maintaining the stability of the overall structure. Moreover, the part where the longitudinal reinforcement 2 and the horizontal stirrups 3 are provided is completely covered by the concrete layer 4, which further enhances the integrity and durability of the structure and ensures the long-term effectiveness of the reinforcement effect. Compared with the prior art, the present application does not require the additional laying of new bricks, nor does it require the addition of additional tools to provide support functions, making the entire construction process more efficient and less costly, meeting construction requirements.
[0045] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
