Abstract
Description
Technical Field
[0001] This utility model relates to the field of building reinforcement technology, specifically to the reinforcement structure for the renovation of building steel structure foundations. Background Technology
[0002] In the renovation of the foundation of old residential buildings, reinforcement and renovation refers to the use of structural components that have been improved or changed to ensure the safe use of existing buildings through certain reinforcement methods. Compared with new buildings, reinforcement and renovation projects make full use of the basic framework of existing buildings. Under the premise of meeting structural reliability, they give full play to and explore the original resources to achieve the purpose of meeting the functional requirements with a smaller investment.
[0003] According to the old house renovation and reinforcement structure with application number CN201821760292.9, the question is how this solution can improve the stability and earthquake resistance of the old house, as well as prevent moisture and heat insulation, thereby improving the practicality of the house.
[0004] However, the following problems still exist in actual use:
[0005] Existing technology enhances the stability of a building by installing triangular supports at the corners of walls. However, this method only supports local corners. Although it can support the walls through steel reinforcement layers, it fails to utilize the structural framework to form multiple triangular support frames within the overall roof structure. This results in low overall roof stiffness, making the building susceptible to localized deformation and collapse under earthquakes or strong winds. Furthermore, the triangular supports at the corners lack coordination with the wall reinforcement structure, causing the corner and wall supports to bear forces independently and fail to work together. During earthquakes or external impacts, stress concentration easily occurs at the connection points between the corners and the walls, reducing the overall seismic performance and stability of the structure. The lack of coordinated support also leads to unclear force transmission paths in the reinforcement structure, weakening the overall stiffness and load-bearing capacity of the building.
[0006] Therefore, this utility model introduces a structural modification and reinforcement structure for building steel structure foundations. Utility Model Content
[0007] To address the shortcomings of existing technologies, this utility model provides a structural modification and reinforcement structure for building steel structures, which has the advantages of providing comprehensive support and reinforcement for the roof and linking the roof support with the wall support and reinforcement, thus solving the problems mentioned in the background technology.
[0008] This utility model provides the following technical solution: a structural reinforcement structure for the renovation of a building steel structure foundation, including a ground and a building frame. Corner reinforcement mechanisms are provided on both sides of the top inner side of the building frame. Each corner reinforcement mechanism includes a triangular truss, a first connecting horizontal frame, a first connecting diagonal frame, a second connecting horizontal frame, a supporting frame, the second connecting diagonal frame, and a triangular reinforcing plate. The left side of the triangular truss is fixedly installed to the left side of the building frame interior. Both sides of the first connecting horizontal frame are fixedly installed to the opposite sides of the triangular truss. The upper surface of the first connecting diagonal frame is fixedly connected to the lower surface of the first connecting horizontal frame. The upper surface of the second connecting horizontal frame is fixedly connected to the lower surface of the first connecting diagonal frame. The left side of the supporting frame is fixedly installed to the left side of the building frame interior. The bottom of the triangular reinforcing plate is fixedly installed to the top of the supporting frame, and the interior of the triangular reinforcing plate is fixedly connected to the outer surface of the triangular truss. The left side of the triangular reinforcing plate is fixedly installed to the left side of the building frame interior. The upper surface of the second connecting diagonal frame is fixedly installed to the lower surface of the second connecting horizontal frame.
[0009] Preferably, wall reinforcement mechanisms are provided on both sides inside the house frame. The wall reinforcement mechanism includes an X-shaped frame, a connecting frame, and a fixed anchor rod. The left side of the X-shaped frame is fixedly installed to the left side inside the house frame. The upper surface of the connecting frame is fixedly installed to the lower surface of the X-shaped frame. The outer surface of the fixed anchor rod is inserted into the interior of the connecting frame. A reinforcement rod is fixedly connected between the lower opening of the X-shaped frame.
[0010] Preferably, the top of the first connecting crossbeam is fixedly connected to the top of the interior of the house frame, and both sides of the second connecting crossbeam are fixedly connected to the bottom of the opposite side of the triangular truss.
[0011] Preferably, the left side of the connecting inclined frame 2 is fixedly installed with the right side of the supporting frame.
[0012] Preferably, the top of the X-shaped frame is fixedly installed to the bottom of the supporting frame, and the left side of the connecting frame is fixedly connected to the left side inside the house frame.
[0013] Preferably, the outer surface of the fixed anchor rod is inserted into the interior of the ground.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. This building steel structure foundation renovation and reinforcement structure utilizes triangular trusses to reinforce the corners of the building frame, allowing for more stable foundation renovation operations. Through the use of connecting horizontal frame one, connecting diagonal frame one, connecting horizontal frame two, support frame, and connecting diagonal frame two, multiple triangular structures are formed during installation, enhancing the structure's shear resistance and improving the shear performance of the corner structure. The use of support frame and triangular reinforcing plates prevents stress concentration under pressure, dispersing stress and achieving a stable stress-bearing effect. This solves the problem of how to reinforce the corners, allowing for foundation renovation operations using multiple triangular reinforcements. It also increases the rigidity of the top of connecting horizontal frame one, preventing deformation and collapse under special circumstances.
[0016] 2. The steel structure foundation renovation and reinforcement structure of this building utilizes X-shaped frames, supporting frames, and reinforcing rods to reinforce the walls. The upper and lower ends of the X-shaped frames form triangular units for reinforcement, preventing poor wall stability during renovation and reinforcement. The use of connecting frames and fixed anchor rods further stabilizes the X-shaped frames during wall reinforcement, improving the reinforcement effect. This solves the problem of how to reinforce walls, allowing for simultaneous reinforcement of wall corners and the entire wall surface, preventing corners from bearing the load alone and improving the overall seismic performance and stability of the structure.
[0017] 3. The steel structure foundation renovation and reinforcement structure of this building uses a two-way linkage between the corner reinforcement mechanism and the wall reinforcement mechanism through a support frame and connecting diagonal frame. This allows multiple triangles to be spliced together on the top inner side of the building frame to form a spatial grid, resisting vertical and lateral loads. X-shaped supports are set on the wall, and triangular units are formed inside the X-shaped supports, thus forming a two-way lateral force resisting system, which significantly improves torsional stiffness and collapse resistance. The bottom is fixed to the ground through fixed anchor rods to form a closed force transmission path, avoiding stress concentration. This ensures that if the top reinforcement fails, the load can be transferred through other paths, improving the reinforcement safety in practice. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1 and Figure 3 The building steel structure foundation renovation and reinforcement structure includes a ground 1 and a building frame 2. Corner reinforcement mechanisms 12 are installed on both sides of the inner top of the building frame 2. Each corner reinforcement mechanism 12 includes a triangular truss 3, a connecting horizontal frame 4, a connecting diagonal frame 5, a connecting horizontal frame 6, a supporting frame 7, a connecting diagonal frame 8, and a triangular reinforcing plate 15. The left side of the triangular truss 3 is fixedly installed to the left side of the interior of the building frame 2. Both sides of the connecting horizontal frame 4 are fixedly installed to the opposite sides of the triangular truss 3. The upper surface of the connecting diagonal frame 5 is fixedly connected to the lower surface of the connecting horizontal frame 4. The upper surface of the connecting horizontal frame 6 is fixedly connected to the lower surface of the connecting diagonal frame 5. The surface is fixedly connected, the left side of the support frame 7 is fixedly installed to the left side inside the house frame 2, the bottom of the triangular reinforcing plate 15 is fixedly installed to the top of the support frame 7, and the inside of the triangular reinforcing plate 15 is fixedly connected to the outer surface of the triangular truss 3. The left side of the triangular reinforcing plate 15 is fixedly installed to the left side inside the house frame 2. The upper surface of the connecting diagonal frame 2 8 is fixedly installed to the lower surface of the connecting horizontal frame 2 6. The top of the connecting horizontal frame 1 4 is fixedly connected to the top of the house frame 2. Both sides of the connecting horizontal frame 2 6 are fixedly connected to the opposite bottom of the triangular truss 3. The left side of the connecting diagonal frame 2 8 is fixedly installed to the right side of the support frame 7.
[0025] Specifically, through the use of triangular truss 3, which serves as a basic support structure, its good shape stability and ability to withstand significant pressure, and its fixed installation on both sides of the interior of the house frame 2, it provides a stable support foundation for the corner reinforcement mechanism 12, thereby enhancing the structural stability at the corner. By using connecting crossbeam 4, which is fixedly installed on the opposite side of triangular truss 3 and at the top of the interior of house frame 2, connecting crossbeam 4 provides lateral connection and reinforcement, connecting triangular truss 3 to the top of house frame 2, making the structure more compact and further enhancing the overall integrity and stability of the corner structure, thus improving the load-bearing capacity and deformation resistance of the corner structure. Through the use of connecting diagonal frame 5, which connects crossbeam 4 and connecting crossbeam 6, diagonal frame 5 forms a diagonal support, which can distribute and transmit some of the pressure, making... The force distribution between connecting crossbeam 1 (4) and connecting crossbeam 2 (6) is more uniform, enhancing the structure's shear resistance and improving the shear performance of the corner structure. Through the use of the support frame 7, which is fixedly installed on the lower surface of the triangular truss 3 and the left side of the interior of the house frame 2, the support frame 7 provides an installation foundation for the connecting diagonal frame 2 (8) and connects with the triangular truss 3 and the house frame 2, increasing the connection points at the corner and improving the overall integrity and stability of the structure. This enhances the connection strength of the corner structure. Furthermore, during use, multiple triangles can be spliced together on the top inner side of the house frame 2 to form a spatial grid, resisting vertical and lateral loads. The use of the triangular reinforcing plate 15, the support frame 7, and the triangular truss 3 disperses stress, preventing stress concentration and fracture, thus improving safety in practical use.
[0026] Please see Figure 2 and Figure 4 Wall reinforcement mechanisms 13 are provided on both sides inside the house frame 2. The wall reinforcement mechanism 13 includes an X-shaped frame 9, a connecting frame 10, and a fixed anchor rod 11. The left side of the X-shaped frame 9 is fixedly installed to the left side inside the house frame 2. The upper surface of the connecting frame 10 is fixedly installed to the lower surface of the X-shaped frame 9. The outer surface of the fixed anchor rod 11 is inserted into the interior of the connecting frame 10. A reinforcement rod 14 is fixedly connected between the lower openings of the X-shaped frame 9. The top of the X-shaped frame 9 is fixedly installed to the bottom of the supporting frame 7. The left side of the connecting frame 10 is fixedly connected to the left side inside the house frame 2. The outer surface of the fixed anchor rod 11 is inserted into the interior of the ground 1.
[0027] Specifically, by fixing the X-shaped frame 9 to both sides of the interior of the house frame 2, the openings at the top and bottom of the X-shaped frame 9 form a triangle with the supporting frame 7 and the reinforcing rod 14. This transforms the original X-shaped frame 9 into multiple triangular units. The triangular structure converts compressive loads into axial forces in the rods, preventing local bending and improving compressive stability. Fixing it to both sides of the interior of the house frame 2 provides basic support for the wall reinforcement mechanism 13, enhancing the stability of the wall in both horizontal and vertical directions, thus improving the stability of the wall structure. The connecting frame 10 is fixedly installed on the lower surface of the X-shaped frame 9 and also fixedly connected to the left side of the interior of the house frame 2. The connecting frame 10 serves to connect and reinforce the wall, connecting the X-shaped frame 9 to the house frame 2 more tightly, further strengthening the integrity of the wall structure. This allows the wall to better cooperate in bearing external forces, thus enhancing the overall integrity of the wall structure. By inserting the fixed anchor rod 11 into the connecting frame 10 and into the ground 1, the fixed anchor rod 11 penetrates deep into the ground 1, providing a reliable fixed foundation for the entire wall reinforcement mechanism 13. This effectively transfers the force on the wall to the ground 1, preventing the wall from tilting or collapsing due to external forces, thereby improving the wall structure's resistance to overturning.
[0028] Working principle: When reinforcing the top and walls of a house, first connect the two sides of the triangular truss 3 to the top and left side of the inner side of the house frame 2, and install the two triangular trusses 3 on both sides of the top of the inner side of the house frame 2. Then, install the connecting crossbeam 4 between the two triangular trusses 3, and fix the top of the connecting crossbeam 4 to the top of the inner side of the house frame 2. Then, install the connecting diagonal brackets 5 on both sides of the bottom of the connecting crossbeam 4, and fix the connecting crossbeam 6 on the bottom of the two sets of connecting diagonal brackets 5. Both sides of the connecting crossbeam 6 are... By fixing the triangular truss 3 to the opposite side, multiple triangular supports are formed when reinforcing the top inner side of the house frame 2, improving the stability of the reinforcement. Then, triangular reinforcing plates 15 are installed on the outer surface of the inner sides of the house frame 2 and the bottom of the triangular truss 3. The bottom of the triangular reinforcing plates 15 is fixedly installed to the top of the support frame 7, and the diagonal brackets 8 are fixedly installed on the opposite side of the support frame 7. The tops of the two sets of diagonal brackets 8 are fixedly connected to the bottom of the connecting crossbeams 6, thus initially reinforcing the inner side walls of the house frame 2. Then, the bottom of the support frame 7 and the diagonal brackets 8 are fixedly installed. An X-shaped frame 9 is installed on the left side, with one side of the X-shaped frame 9 fixedly connected to one side of the interior of the house frame 2, further reinforcing the wall. A reinforcing rod 14 is fixedly connected to the lower opening of the X-shaped frame 9, forming a triangular support unit for reinforcement. Finally, a connecting frame 10 is fixedly installed between the bottom of the X-shaped frame and the top of the ground 1. Two sets of anchor rods 11 are installed on both sides inside the connecting frame 10 to ensure the stability of the X-shaped frame 9 and the connecting frame 10, further stabilizing the reinforcement. This includes a triangular truss 3 and a connecting crossbeam 4. The connecting diagonal frame 1 (5), connecting horizontal frame 2 (6), supporting frame 7, connecting diagonal frame 2 (8), X-shaped frame 9, connecting frame 10, and fixed anchor rod 11 are all steel structures. When installed and in use, multiple triangles are spliced together on the top inner side of the house frame 2 to form a spatial grid, resisting vertical and horizontal loads. X-shaped supports are set on the walls to form a two-way lateral force resisting system, which significantly improves torsional stiffness and anti-collapse capacity. The bottom is fixed to the ground 1 through the fixed anchor rod 11 to form a closed force transmission path, avoiding stress concentration. This ensures that when the top reinforcement fails, the load can be transferred through other paths.
