Abstract
Description
Technical Field
[0001] This utility model relates to the field of old house renovation technology, specifically to a beam reinforcement structure for old house renovation. Background Technology
[0002] Before the 1980s, most houses used a mud-walled, tiled-roof design, with the core components being the walls and the roof. The walls, as the supporting structure, bore the entire weight of the roof; the roof itself was cleverly constructed from a wooden frame and tiles. The wooden frame was securely installed on the walls, and the tiles were tightly laid on top of the wooden frame, working together to protect against wind and rain. However, after more than forty years of weathering and exposure to the elements, the walls of these houses gradually cracked, significantly weakening their load-bearing capacity and rendering them unable to effectively support the weight of the roof. Simultaneously, the wooden roof frame became severely damaged by insects, becoming extremely fragile and at risk of breaking and collapsing at any time. These houses were therefore classified as dangerous buildings. To properly address this problem, renovation of dangerous buildings became the preferred solution. Current technical practices typically involve adding reinforced mortar strips to the walls to enhance their load-bearing capacity and ensure their stable support of the roof. Meanwhile, for the wooden roof frame that has been damaged by insects or deteriorated, flat iron is used for reinforcement to improve its structural strength and stability. Through these renovation measures, these dilapidated houses have been revitalized and have regained the standard of safe living. There may already be technical solutions to the above problems in the existing technology, but this case aims to provide an alternative or replacement technical solution. Utility Model Content
[0003] To achieve the above objectives, this utility model provides the following technical solution: a beam reinforcement structure for old house renovation, comprising: a T-shaped extension block, a lifting concave limiting block, and a lifting extension structure. The T-shaped extension block and the lifting concave limiting block are interconnected through the lifting extension structure. The lifting extension structure includes: a lifting threaded rod, a lifting threaded tube, a lifting helical gear set, a lifting drive shaft, a lifting drive handle, a lifting slider set, a pair of lifting gear sets, a pair of lifting extrusion handles, several lifting extrusion threaded tubes, several lifting extrusion threaded rods, a pair of lifting extrusion plates, several lifting extrusion balls, and an extension assembly.

The lifting drive shaft is inserted into the lifting concave limiting block. The lifting helical gear set is mounted on the lifting drive shaft and the lifting threaded tube. The lifting drive handle is mounted on the lifting drive shaft. The lifting concave limiting block has a lifting slide groove set. The lifting slider set is mounted on the T-shaped extension block, and the lifting slider set is movably inserted into the inner side of the lifting threaded tube. Installed on the inner side of the lifting concave limiting block, a plurality of lifting extrusion threaded tubes are inserted into the lifting concave limiting block in an L-shape, a plurality of lifting extrusion threaded rods are respectively movably inserted into the inner side of the plurality of lifting extrusion threaded tubes, a pair of lifting gear sets are respectively fitted onto the plurality of lifting extrusion threaded tubes, a pair of lifting extrusion handles are respectively installed on the pair of lifting gear sets, a pair of lifting extrusion plates are respectively installed on the plurality of lifting extrusion threaded rods, a plurality of lifting extrusion balls are respectively inserted into the pair of lifting extrusion plates, and the extension component is installed on the T-shaped extension block;
[0005] It should be noted that, as described above, rotating the lifting drive handle drives the lifting drive shaft, which in turn drives the lifting helical gear set, which in turn drives the lifting threaded rod on the lifting helical gear set, which in turn drives the lifting threaded tube on it, which in turn drives the T-shaped extension block on it, causing the T-shaped extension block to move stably along the inner side of the lifting concave limiting block. At the same time, the lifting slider set and the lifting slide set work together to achieve stable lifting and limiting. Similarly, operating a pair of lifting extrusion handles drives a pair of lifting gear sets, which in turn drive several lifting extrusion threaded tubes on them to rotate. These lifting extrusion threaded tubes then drive the lifting extrusion threaded rods on their inner sides, which in turn drive a pair of lifting extrusion plates to perform L-shaped coloring. This is achieved by using several lifting extrusion balls on the pair of lifting extrusion plates to perform L-shaped extrusion limiting, thereby fixing the T-shaped extension block inside the lifting concave limiting block.
[0006] Preferably, the extension assembly includes: a pair of extension blocks, a pair of extension shafts, two pairs of extension concave blocks, a pair of I-shaped rods, a pair of extension threaded rods, a pair of extension sliders, a pair of extension threaded tubes, and a pair of extension handles;

The pair of expansion blocks are respectively inserted into the inner side of the pair of T-shaped expansion slots through the expansion shaft. The pair of T-shaped expansion slots are respectively provided with expansion drive slots. The pair of expansion threaded rods are respectively inserted into the inner side of the pair of expansion drive slots. The pair of expansion threaded tubes are respectively inserted into the pair of expansion sliders, and the pair of expansion sliders are respectively movably inserted into the inner side of the pair of expansion drive slots.

The pair of I-shaped rods are respectively inserted into the two pairs of expansion concave blocks. The pair of expansion handles are respectively installed on the pair of expansion threaded rods.
[0008] It should be noted that, as described above, the rotation of a pair of extending threaded rods drives a pair of extending threaded tubes on them to extend and retract horizontally along the outer side of the pair of extending threaded rods. The pair of extending threaded tubes drive the extending sliders on them, causing the pair of extending sliders to extend and retract horizontally along the inner side of the extending drive groove. The extending sliders drive the extending concave blocks on them, which in turn drive the I-shaped rods on them. The I-shaped rods drive another extending concave block, which pushes the extending block, causing the extending block to rotate along the extending axis.
[0009] Preferably, the T-shaped extension block is provided with a plurality of electromagnetic telescopic rods.
[0010] Preferably, a plurality of telescopic grooves are provided on each pair of the expansion blocks.
[0011] Preferably, a level is provided on the T-shaped extension block.
[0012] Preferably, a plurality of extension tilting rods are provided on the inner side of a pair of T-shaped extension slots. Beneficial effects
[0013] This utility model provides a beam reinforcement structure for old house renovation. It offers the following advantages compared to existing technologies: Through a unique lifting and expansion structure design, it achieves a stable connection and flexible adjustment between the T-shaped expansion block and the lifting concave limiting block. Rotating the lifting drive handle drives the lifting threaded rod to rotate via the lifting drive shaft and lifting helical gear set, thereby causing the lifting threaded tube and T-shaped expansion block to move stably within the lifting concave limiting block. Simultaneously, it works in conjunction with the lifting slider assembly and lifting slide groove assembly to achieve precise positioning. Furthermore, operating the lifting squeeze handle drives the lifting gear set to rotate, causing the lifting squeeze threaded tube and threaded rod to move, allowing the lifting squeeze plate to move in an L-shape. The lifting squeeze ball achieves fixed positioning of the T-shaped expansion block. An additional expansion component is provided; rotating the expansion threaded rod drives the expansion threaded tube and expansion slider to extend and retract horizontally. Then, through the cooperation of the expansion concave block and I-shaped rod, the expansion block is pushed to rotate along the expansion axis, achieving multi-functional expansion. This design is not only easy to operate but also structurally stable, with reliable lifting and expansion, meeting the needs of various application scenarios. Attached Figure Description
