Description

Technical Field

[0001] This utility model relates to the field of building structure reinforcement technology, and in particular to a building structure reinforcement device. Background Technology

[0002] As an important component in building structures that enhances wall stability and improves seismic resistance, structural columns often suffer damage during long-term use due to factors such as earthquakes, weathering erosion, and construction defects. This damage can manifest as concrete spalling, exposed and corroded reinforcing bars, and cracks. Once a structural column is damaged, its load-bearing capacity and seismic performance will decrease significantly, seriously threatening the safety of the building. Therefore, a structural reinforcement device is needed to reinforce the damaged areas. Existing structural column reinforcement methods typically involve repairing and enlarging the cross-section. This is done by adding concrete and reinforcing bars to the surface of the structural column, increasing its cross-sectional dimensions and reinforcement to improve its load-bearing capacity. However, this method requires formwork, reinforcing bar tying, and concrete pouring, which are cumbersome and time-consuming. Furthermore, the added weight of the concrete can place an extra burden on the building foundation. In addition, improper treatment of the interface between the old and new concrete can easily lead to poor overall integrity. Utility Model Content

[0003] This utility model relates to a building structure reinforcement device to solve the problems mentioned in the background art, such as the commonly used repair and enlargement method for reinforcing structural columns, which has problems such as complicated construction, long construction period, increased burden on building foundation, and poor integrity due to improper treatment of the interface between new and old concrete.

[0004] This utility model provides a building structure reinforcement device, specifically including: a fixing frame; two fixing frames are symmetrically arranged, and a reinforcing protective wall is snapped into the front and rear sides of the two fixing frames. Two reinforcing frames are symmetrically snapped into the outer side walls of the two reinforcing protective walls. A main locking rod is snapped into the reinforcing frame, and a secondary locking rod is inserted into the rear side of the main locking rod.

[0005] Furthermore, both fixed frames are square column structures, and connecting seats are symmetrically provided on the upper and lower sides of the front and rear side walls at opposite ends of the two fixed frames. The connecting seats are fixedly connected to the structural column by bolts.

[0006] Furthermore, both of the two symmetrical reinforced protective walls are L-shaped. Connecting grooves are provided at the upper and lower ends of the outer side of the inner wall of the two reinforced protective walls. The connecting grooves on the inner wall of the reinforced protective wall are engaged with the connecting seats of the fixed frame on the same side. Fixed slots are provided in the middle of the outer wall of the reinforced protective wall and on the left and right sides. Two sets of fixed slots are provided symmetrically in the upper and lower parts.

[0007] Furthermore, the inner wall of the reinforcing frame and the outer wall of the reinforcing protective wall are tightly fitted together. Rectangular fixing blocks are fixedly installed in the middle of the side wall where the reinforcing frame and the reinforcing protective wall are fitted together, as well as on the left and right sides. The fixing blocks are inserted into the fixing slots on the outer wall of the reinforcing protective wall. The middle of the outer wall of the reinforcing frame is concave and the cross-section is concave.

[0008] Furthermore, the main locking rod is engaged in the inner groove of the outer wall of the reinforcing frame, and locking connecting blocks are connected to the left and right rear ends of the main locking rod. The side walls of the locking connecting blocks are engaged in the end of the reinforcing frame, and the locking connecting blocks are fixedly connected to the fixed frame by bolts. A rectangular combination slot is opened in the middle of the outer wall of the rear end of the locking connecting block.

[0009] Furthermore, the secondary locking rod is engaged in the reinforcing frame inserted into the reinforcing protective wall on the rear side of the fixed frame. The front ends of the left and right sides of the secondary locking rod are fixedly connected with inwardly recessed combination blocks. The combination blocks are engaged in the combination slots opened in the locking connecting block at the rear end of the main locking rod. Locking pressure plates are provided on the side wall of the locking connecting block outside the combination slot. The locking pressure plates are connected to the bolts on the locking connecting block.

[0010] This utility model provides a building structure reinforcement device, which has the following beneficial effects:

[0011] 1. The fixed frame, with its symmetrically distributed connecting seats, enables the external force to be evenly transmitted to the structural column, significantly enhancing the stability of the connection between the fixed frame and the structural column. The reinforced retaining wall adopts an "L"-shaped structure design, which can perfectly fit the right-angle contour of the structural column. The connecting groove on its inner wall precisely engages with the connecting seat of the fixed frame, which not only enables the rapid positioning and installation of the reinforced retaining wall, but also forms a stable constraint after installation, effectively limiting the displacement of the retaining wall. The fixing slots on the outer wall of the reinforced retaining wall and the fixing blocks of the reinforced frame cooperate with each other, interlocking tightly like a mortise and tenon structure, greatly improving the connection strength between components and ensuring that the entire reinforcement system is stable and reliable.

[0012] 2. The main locking rod and the reinforcing frame are tightly connected by a groove and a protrusion. At the same time, it is longitudinally locked to the secondary locking rod through a combination of slots and blocks. With the secondary tightening effect of the locking plate, a comprehensive and multi-layered stable constraint system is constructed from both horizontal and vertical dimensions. This design can effectively resist the displacement and loosening of components under external forces, ensuring that the reinforcement device maintains structural stability during long-term use and providing continuous and reliable reinforcement protection for the structural column.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides a building structure reinforcement device, including: a fixed frame 1, two fixed frames 1 are symmetrically arranged, a reinforcement wall 2 is snapped into the front and rear sides of each of the two fixed frames 1, two reinforcement frames 3 are symmetrically snapped into the outer side walls of the two reinforcement wall walls 2, a main locking rod 4 is snapped into the reinforcement frame 3, and a secondary locking rod 5 is inserted into the rear side of the main locking rod 4. Both fixed frames 1 are square column structures. Connecting seats 101 are symmetrically arranged on the upper and lower sides of the front and rear side walls of the two fixed frames 1 at opposite ends. The connecting seats 101 are fixedly connected to the structural column by bolts. Specifically, by fixing the fixed frame 1 to the structural column with bolts through the connecting seats 101, a quick and stable connection between the fixed frame 1 and the structural column can be achieved, avoiding the thermal damage to the structural column caused by traditional welding. Moreover, the symmetrical arrangement of the connecting seats 101 can make the external force on the fixed frame 1 evenly distributed, enhance the stability of the connection between the entire reinforcement device and the structural column, and prevent the fixed frame 1 from shifting or loosening when under force.

[0027] The two symmetrical reinforced retaining walls 2 are both L-shaped. Connecting grooves 201 are provided at the upper and lower ends of the outer sides of the inner walls of the two reinforced retaining walls 2. The connecting grooves 201 on the inner walls of the reinforced retaining walls 2 are engaged with the connecting seats 101 of the fixing frames 1 on the same side. Fixing slots 202 are provided in the middle and on both sides of the outer walls of the reinforced retaining walls 2. Two sets of fixing slots 202 are provided symmetrically in the upper and lower sections. Specifically, the L-shaped reinforced retaining walls 2 can tightly fit the right-angle structure of the structural column, simultaneously reinforcing two adjacent sides of the structural column and effectively filling the gaps caused by damage to the structural column. In areas with weak stress, the connecting groove 201 engages with the connecting seat 101 of the fixed frame 1, which not only facilitates the quick installation and positioning of the reinforced retaining wall 2, but also restricts the displacement of the reinforced retaining wall 2 after installation, so that it forms a stable connection structure with the fixed frame 1. The fixing slot 202 on the outer wall of the reinforced retaining wall 2 provides a precise positioning and connection point for the installation of the reinforced frame 3. By cooperating with the fixing plug 301 on the reinforced frame 3, the connection strength between the reinforced retaining wall 2 and the reinforced frame 3 is enhanced, so that the entire reinforcement device can be stressed in all directions, thereby improving the reinforcement effect on the structural column.

[0028] The inner wall of the reinforcing frame 3 and the outer wall of the reinforcing retaining wall 2 are tightly fitted together. Rectangular fixing blocks 301 are fixedly installed at the middle and on both sides of the side walls where the reinforcing frame 3 and the reinforcing retaining wall 2 are fitted together. The fixing blocks 301 are inserted into the fixing slots 202 on the outer wall of the reinforcing retaining wall 2. The middle of the outer wall of the reinforcing frame 3 is concave and its cross-section is concave. Specifically, by tightly fitting the reinforcing frame 3 and the reinforcing retaining wall 2, the structural column can be further wrapped and reinforced, forming a multi-layered protective structure. The insertion of the fixing blocks 301 into the fixing slots 202... The fit ensures a tight connection between the reinforcing frame 3 and the reinforcing wall 2, preventing relative sliding under stress and ensuring the overall stability of the reinforcement device. The concave "U"-shaped structure in the middle of the outer wall of the reinforcing frame 3 provides a suitable slot for the subsequent installation of the main locking rod 4, allowing the main locking rod 4 to be firmly locked onto the reinforcing frame 3. At the same time, this concave design also limits and protects the main locking rod 4, preventing it from detaching from the reinforcing frame 3 due to external forces during use, thus ensuring the locking effect of the main locking rod 4 on the reinforcing frame 3 and the entire reinforcement device.

[0029] The main locking rod 4 is engaged in the inner groove of the outer wall of the reinforcing frame 3. Locking connecting blocks 401 are connected to the rear ends of both sides of the main locking rod 4. The side walls of the locking connecting blocks 401 are engaged at the ends of the reinforcing frame 3. The locking connecting blocks 401 are fixedly connected to the fixed frame 1 by bolts. A rectangular combination slot 402 is provided in the middle of the outer wall of the rear end of the locking connecting blocks 401. Specifically, by engaging the main locking rod 4 in the inner groove of the reinforcing frame 3, it can provide lateral restraint to the reinforcing frame 3, preventing horizontal displacement and enhancing the horizontal stability of the reinforcement device. Qualitatively, the locking connecting block 401 is connected to the fixed frame 1 by bolts, further securing the main locking rod 4 to the fixed frame 1, so that the main locking rod 4, the reinforcing frame 3, and the fixed frame 1 form a stable overall structure. The combination slot 402 provides an interface for the installation and connection of the secondary locking rod 5. By cooperating with the combination slot 501 on the secondary locking rod 5, the main locking rod 4 and the secondary locking rod 5 are mutually locked, which strengthens the reinforcing device in the longitudinal direction, so that the entire reinforcing device can form a stable constraint system in both the horizontal and longitudinal directions, significantly improving the reinforcement strength and stability of the structural column.

[0030] The secondary locking rod 5 is engaged with the reinforcing frame 3 inserted into the reinforcing wall 2 on the rear side of the fixed frame 1. The left and right front ends of the secondary locking rod 5 are fixedly connected to inwardly recessed combination blocks 501. The combination blocks 501 are engaged with the combination slots 402 opened in the locking connecting block 401 at the rear end of the main locking rod 4. Locking pressure plates 6 are provided on the side wall of the locking connecting block 401 outside the combination slots 402. The locking pressure plates 6 are connected to the bolts on the locking connecting block 401. Specifically, the secondary locking rod 5 is engaged with the combination slots 402 of the main locking rod 4 through the combination blocks 501, thus locking the rod in the longitudinal direction... The various components of the reinforcement device are tightly connected together to form a three-dimensional reinforcement network, which enhances the longitudinal load-bearing capacity and stability of the entire reinforcement device. The locking plate 6 and the bolts on the locking connecting block 401 can lock and tighten the connection between the combination block 501 and the combination slot 402 for a second time, preventing the secondary locking rod 5 from loosening or falling off due to vibration, external impact or other factors during use, ensuring the reliability of the connection between the main locking rod 4 and the secondary locking rod 5, and further improving the reinforcement effect of the reinforcement device on the structural column and the safety of long-term use.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When using this building structure reinforcement device, firstly, the connecting seats 101 of the two fixed frames 1 are fixedly installed to the corner of the building structural column that needs reinforcement using bolts. Then, the "L"-shaped reinforcement retaining wall 2 is snapped into the connecting seat 101 of the fixed frame 1 on the same side through the connecting groove 201 opened in the inner wall, so that the connecting groove 201 is snapped into the connecting seat 101, completing the initial positioning of the reinforcement retaining wall 2. Then, the fixing block 301 of the reinforcement frame 3 is aligned with the fixing slot 202 on the outer wall of the reinforcement retaining wall 2, and the fixing block 301 is gently inserted into the fixing slot 202, so that the inner wall of the reinforcement frame 3 and the outer wall of the reinforcement retaining wall 2 are tightly fitted. Finally, the main locking rod 4 is snapped into the inner groove of the outer wall of the reinforcement frame 3, so that the main locking rod 4... The locking connecting blocks 401 at the rear ends of the left and right sides are snapped into the end of the reinforcing frame 3. Then, the combination locking block 501 of the secondary locking rod 5 is aligned with the combination slot 402 opened in the locking connecting block 401 at the rear end of the main locking rod 4. The combination locking block 501 is forcefully inserted into the combination slot 402, so that the secondary locking rod 5 is snapped into the reinforcing frame 3 inserted into the reinforcing wall 2 on the rear side of the fixed frame 1. Finally, the locking pressure plate 6 is installed, and the locking pressure plate 6 and the locking connecting block 401 are fixedly installed on the fixed frame 1 with bolts. The connection between the combination locking block 501 and the combination slot 402 is locked and tightened a second time to ensure that the secondary locking rod 5 is installed firmly and will not loosen or fall off. The left and right ends of the secondary locking rod 5 are also fixedly connected to the fixed frame 1 with bolts. Example

[0033] Based on the existing reinforcement device, the surfaces of the fixed frame 1, the reinforced wall 2, the reinforced frame 3, the main locking rod 4 and the secondary locking rod 5 are all sprayed with an anti-corrosion coating. The anti-corrosion coating can be epoxy resin anti-corrosion paint, which has good chemical stability and can effectively resist the erosion of the device by rainwater, acids, alkalis and other corrosive substances.
