Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an aluminum-wood combined internal corner formwork structure. Background Technology

[0002] Internal corner formwork structures are used for shaping internal and external corners in buildings. They are mostly composed of metal formwork and wooden formwork. The metal formwork forms the main frame and is often presented in the form of right-angled profiles with connecting holes or slots on the edges. The wooden formwork is attached to the inside or side of the metal formwork and connected to the metal parts by fasteners such as bolts and pins. Some structures include adapters or connecting plates for the transition between the metal and wooden formwork. Some also have wooden square installation slots to facilitate the fixing of the wooden formwork. The whole structure forms a combined formwork system that is suitable for internal and external corners.

[0003] The internal corner formwork structure combines metal and wooden formwork. The rigidity of the metal frame is used to position the right-angle contour of the internal and external corners, while the wooden formwork fills the joint surface. The metal formwork is fixed to the adjacent formwork with pins and bolts through the edge connection holes, forming an overall support system. The wooden formwork is attached and the joints are compacted by fasteners. Transition pieces or connecting plates ensure a tight fit between the metal and wooden formwork. When pouring concrete, the formwork system resists lateral pressure and ensures the forming accuracy of the internal and external corners by relying on the rigid support of the connectors and the flexible fit of the wooden formwork.

[0004] In existing technologies, when using aluminum formwork systems for construction, the traditional approach for internal corners between beams and between beams and columns is to use custom-made internal corner aluminum formwork combined with aluminum and wood for support. However, due to the significant variations in beam and column cross-sections across different floors in public buildings, the turnover rate of custom-made internal corner aluminum formwork is low, and the cost of using aluminum formwork is high. In practice, an aluminum-wood combination formwork method is often used for internal corners with significant structural changes. However, the traditional aluminum-wood combination reinforcement method often leads to quality problems such as concrete leakage and misalignment, and the reuse rate of wooden formwork is also relatively low. Therefore, an aluminum-wood combined internal corner formwork structure is proposed to solve these problems. Utility Model Content

[0031] 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.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an aluminum-wood combined internal corner formwork structure, including a column 1 that provides support for the formwork structure, allowing the formed beams 2 to be stably connected to it. Two beams 2 are fixedly connected to the front side of the column 1; the beams 2 are the desired output of the formwork structure. An aluminum plate 12 is fixedly connected to the front side of the column 1, serving as auxiliary support and initial forming, providing a stable installation foundation for the upper base wooden board 11, and also contributing to the shaping of the formwork structure and cooperating with other components. Two base wooden boards 11 are fixedly connected to the top of the aluminum plate 12; the base wooden boards 11 can be cut and shaped according to site conditions, reducing material waste from pure aluminum plates.

[0033] Both bottom wooden boards 11 have splicing steel plates 3 fixedly connected to their top ends. The splicing steel plates 3, together with two outer rotating steel plates 6 and an inner rotating steel plate 7, and fixing components, constitute a splicing module. When the height of the top module is less than the height of the beam 2 to be poured, the splicing module can be connected to the top module and adjusted to a suitable height. A top steel plate 5 is fixedly connected to the top end of the splicing steel plate 3. The top steel plate 5, together with three outer rotating steel plates 6 and an inner rotating steel plate 7, constitutes the top module. Side ribs 4 are fixedly connected to the front side of the top steel plate 5. The side ribs 4 are distributed on both the splicing steel plate 3 and the top steel plate 5 for connection with aluminum or wooden formwork.

[0034] Multiple outward-rotating steel plates 6 are fixedly connected to the right side of the top steel plate 5 on the left side, and multiple inward-rotating steel plates 7 are fixedly connected to the left side of the top steel plate 5 on the right side. The outward-rotating steel plates 6 and the inward-rotating steel plates 7 together constitute the rotatable connection part of the template structure. The outward-rotating steel plates 6 and the inward-rotating steel plates 7 are respectively connected to the supporting steel plates on the left and right sides. By rotating the outward-rotating steel plates 6 and the inward-rotating steel plates 7, the template structure can flexibly adjust its angle at the inside corner to adapt to the needs of building structures at different angles, facilitating the installation and disassembly of the template. An aluminum plate 2 9 is fixedly connected to the front side of the splicing steel plate 3, and an aluminum plate 1 8 is fixedly connected to the top of the aluminum plate 2 9. The aluminum plates 2 9 and 1 8 cooperate with each other to further improve the shape and strength of the template structure.

[0035] Two fixed aluminum plates 16 are fixedly connected to the opposite side of column 1. These plates assist in fixing and strengthening the overall stability of the formwork structure. Together with the side wooden boards 13 and triangular ribs 14, they enhance the lateral support strength of the formwork structure. Side wooden boards 13 are fixedly connected to the front of each of the two fixed aluminum plates 16. The side wooden boards 13 increase the lateral stability and cushioning performance of the formwork structure and provide an installation base for the triangular ribs 14. Triangular ribs 14 are fixedly connected to the outer side of the side wooden boards 13. Utilizing the stability principle of triangles, the triangular ribs 14 enhance the compressive and deformation resistance of the formwork structure on the side, ensuring the overall stability of the formwork structure during construction. The inner side of the inner rotating steel plate 7 is equipped with fixing components for easy fixation of the corner plates.

[0036] Reference Figure 1 , Figure 2 , Figure 4 The fixing component includes a support rod 17, whose outer side is slidably connected to the inside of the inner rotating steel plate 7. The support rod 17 serves as the basic frame of the fixing component, providing support and guidance. Its slidable connection to the inner rotating steel plate 7 allows the fixing component to be flexibly adjusted during installation, while also providing installation space and a supporting foundation for other internal components, ensuring the stability and reliability of the entire fixing component structure. An electric push rod 18 is fixedly connected internally to the support rod 17. The electric push rod 18 converts electrical energy into mechanical energy, achieving linear reciprocating motion. It can control the extension and retraction of the connecting column 19 according to actual needs, thereby driving the movement of other components.

[0037] A connecting column 19 is fixedly connected to the drive end of the electric push rod 18. One end of the connecting column 19 is connected to the drive end of the electric push rod 18 to receive the power transmitted by the electric push rod 18; the other end is fixedly connected to the contact table 20 to transmit the power to the contact table 20. The contact table 20 is fixedly connected to the front side of the connecting column 19. When the connecting column 19 moves under the drive of the electric push rod 18, the contact table 20 is pushed accordingly. A support column 21 is fixedly connected inside the support rod 17, providing support for the components connected to it. Multiple fixed columns 22 are fixedly connected to the outside of the support column 21. The fixed columns 22 provide the mounting and movement track for the spring 23 and the slider 24, ensuring that the spring 23 and the slider 24 maintain a stable movement trajectory during operation.

[0038] Multiple fixed posts 22 are fixedly connected to springs 23 on their outer sides. When the contact platform 20 pushes the slider 24, the springs 23 are stretched, undergo elastic deformation, and store elastic potential energy. When the contact platform 20 returns to its original position, the springs 23 release the elastic potential energy, causing the slider 24 to return to its original position. Multiple sliders 24 are slidably connected to the outer side of the support rod 17. The sliders 24 cooperate with the fixed posts 22 and springs 23, and are locked inside the inner rotating steel plate 7. Multiple connecting rods 25 are fixedly connected to the outer side of the connecting post 19. Fixed rings 26 are fixedly connected to the outer side of the multiple connecting rods 25. When the connecting post 19 moves under the drive of the electric push rod 18, the connecting rods 25 slide in the grooves inside the support rod 17, causing the fixed rings 26 to slide on the outer side of the support rod 17.

[0039] Reference Figure 1 , Figure 2 , Figure 4 An angle steel 10 is fixedly connected to the front side of the bottom wooden board 11. The front side of the angle steel 10 is fixedly connected to the rear side of the aluminum plate 2 9. The angle steel 10 serves to strengthen the connection and enhance the structural stability. The special shape of the angle steel 10 allows it to provide support in two directions, effectively enhancing the connection strength between the bottom wooden board 11 and the aluminum plate 2 9. The inner sides of multiple outer rotating steel plates 6 are rotatably connected to the outer sides of the inner rotating steel plates 7. The top of the aluminum plate 2 9 is fixedly connected to the aluminum plate 4 15, further improving the front surface of the template structure. Together with the aluminum plate 2 9 and the aluminum plate 1 8, they form a complete and flat forming surface.

[0040] The front side of the side wooden board 13 is fixedly connected to the rear side of the aluminum plate 15, and the rear side of the top steel plate 5 is in contact with the front side of the column 1. The other ends of multiple springs 23 are fixedly connected to the inside of the slider 24, and the inner side of the slider 24 is slidably connected to the outer side of the fixed column 22. The front side of the contact platform 20 is in contact with the rear side of multiple sliders 24, and the movement of the contact platform 20 drives the movement of the sliders 24, realizing the extension movement of the sliders 24. The inner side of the fixing ring 26 is slidably connected to the outer side of the support rod 17, limiting the outer side of the outer rotating steel plate 6. Multiple grooves are opened inside the support rod 17, and the outer side of the connecting rod 25 is slidably connected to the inside of the grooves. The grooves provide guidance for the connecting rod 25, allowing it to move stably in a fixed direction.

[0041] Working principle: During pouring, workers fix aluminum plate 12 and fixed aluminum plate 16 in appropriate positions on column 1. Then, they fix the tops of two base wooden boards 11 to the tops of aluminum plate 12. The side wooden boards 13 are fixed to the far side of the tops of the two base wooden boards 11. The two splicing steel plates 3 and two top steel plates 5 are rotated to drive multiple outer rotating steel plates 6 and inner rotating steel plates 7 to adjust the angle of the concave corner. They are then fixed by the components connected by the support rod 17. The two splicing steel plates 3 and top steel plates 5, after adjusting the angle, are fixed to the near side of the two base wooden boards 11. Aluminum plate 9 is fixed to the front side of the base wooden board 11. Aluminum plate 8 and aluminum plate 15 are fixed to the top left and right sides of the top of the second 9 respectively. The rear side of aluminum plate 8 is connected to splicing steel plate 3 and top steel plate 5. The rear side of aluminum plate 15 is connected to side wooden board 13. The rear side of side wooden board 13 is fixed to fixed aluminum plate 16. All the above components are connected to form an adjustable angle aluminum-wood combination structure. This structure combines the high strength, wear resistance and reusability of aluminum alloy with the easy processing and cost advantages of wood. Through the flexible angle adjustment function, it can adapt to the needs of building construction for the construction of internal corner formwork at different angles, significantly improving the versatility of the formwork and construction efficiency.

[0042] When adjusting the internal angle, the worker first rotates the two splicing steel plates 3 and the top steel plate 5 to drive multiple outer rotating steel plates 6 and inner rotating steel plates 7 to the appropriate angle. Then, the support rod 17 is inserted into the overlapping and appropriately positioned holes of the outer rotating steel plates 6 and inner rotating steel plates 7. The electric push rod 18 is then activated, which drives the connecting column 19 fixedly connected to its drive end to move. The movement of the connecting column 19 drives the contact table 20 to move, causing the contact table 20 to push the slider 24 outward. At this time, the spring 23 follows the movement of the slider 24, undergoes elastic deformation, and stores elastic potential energy. When the electric push rod 18 moves in the reverse direction, it releases elastic potential energy to drive the slider 24 back to its original position. During the movement of the connecting column 19, the fixing ring 26 is also driven to move through the connecting rod 25, so that the fixing ring 26 is fixed on the outside of the outer rotating steel plate 6. Through the synergistic effect of the slider 24 and the outer rotating steel plate 6, the outer rotating steel plate 6 and the inner rotating steel plate 7 can be fixed, which simplifies the connection process between the outer rotating steel plate 6 and the inner rotating steel plate 7, improves the efficiency of template installation and disassembly, reduces construction time, speeds up the project progress, reduces the labor intensity of workers, and improves the safety of operation.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
