Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a modular building formwork structure. Background Technology

[0002] As a core supporting component in concrete pouring and forming, the structural rationality and ease of assembly of building formwork directly affect construction efficiency, project quality, and cost control. With the promotion of prefabricated buildings and efficient construction concepts, modular building formwork has been widely used in the construction of concrete structures such as beams, slabs, columns, and walls due to its advantages such as flexible assembly according to construction needs, adaptability to different component sizes, and reusability of formwork units.

[0003] An existing patent (publication number: CN218715147U) discloses a modular building formwork structure. It includes a formwork body, with symmetrically arranged adapter grooves at the top and bottom of the front side, a guide groove in the center of the front side, locking components symmetrically and movably connected to the top and bottom of the right side of the front side, adapter blocks symmetrically and movably connected to the top and bottom of the back side, and a guide column movably connected to the center of the back side. This design facilitates storage, allows for the combination of multiple formworks, and provides a supporting structure to maintain stability.

[0004] However, the above-mentioned modular building formwork, which uses a plug-in splicing method, lacks a sealing structure at the joints of the formwork units. Due to the high-frequency vibration generated during concrete pouring, the joints of the formwork are prone to not being completely and tightly fitted, resulting in gaps. At this time, during the concrete pouring process, concrete slurry will seep out from the gaps, resulting in slurry leakage. Slurry leakage not only leads to appearance defects such as honeycomb, pitting, and exposed reinforcement on the surface of concrete components, but in severe cases, it can also change the cross-sectional dimensions and internal density of the concrete components, reducing the load-bearing capacity and structural stability of the components. Utility Model Content

[0005] The purpose of this application is to provide a modular building formwork structure that enables rapid insertion and splicing of the main body of the building formwork through the action of slots and plugs. At the same time, the sealing gasket inside the slot directly fills the potential gap between the two, blocking the leakage channel of concrete slurry from the root. Then, the cooperation of tensioning components and L-shaped connecting blocks further enhances the tightness of the connection between adjacent main bodies of the building formwork. These advantages solve the problems mentioned in the background art.

[0006] This application provides a modular building formwork structure with the following technical solution: A modular building formwork structure includes multiple sets of building formwork bodies. Each set of building formwork bodies has two slots on its outer side. A sealing gasket is fixedly connected to the inner side of each slot. A rod is fixedly connected to the other side of each set of building formwork bodies, with the outer side of the rod inserted into the inner side of the slot. An L-shaped connecting block is fixedly connected to the outer side of each set of building formwork bodies. A tensioning assembly is provided on the outer side of each set of building formwork bodies. The tensioning assembly includes a mounting frame fixedly connected to the outer side of the building formwork body. A lead screw is rotatably connected to the outer side of the mounting frame. A movable seat is threadedly connected to the outer side of the lead screw. A mating block is fixedly connected to the outer side of the movable seat. The outer side of the L-shaped connecting block is inserted into the inner side of the mating block. The mating block and the L-shaped connecting block are fixedly connected by bolts. A hinge seat is fixedly connected to the outer side of each set of building formwork bodies. A grounding plate is hinged to the inner side of each hinge seat. Multiple grounding bolts are installed on the outer side of each grounding plate.

[0007] By adopting the above technical solution, the cooperation between the slot and the insert rod enables the rapid splicing of multiple sets of building formwork bodies. The sealing gasket inside the slot can fill the potential gap between the insert rod and the slot, directly blocking the channel for concrete grout to seep out from the connection and preventing grout leakage. Then, by utilizing the cooperation between the L-shaped connecting block and the tensioning component, the screw rod drives the moving seat to move, thereby driving the L-shaped connecting block to move, further enhancing the tightness of the connection between adjacent building formwork bodies, reducing the loosening of the connection caused by concrete vibration, and indirectly reducing the risk of grout leakage. Afterwards, the hinged seat supports the grounding plate, which is fixed to the ground by grounding bolts, improving the installation stability of the entire formwork structure, preventing the overall formwork from shifting and damaging the sealing state of the connection, and helping to ensure the anti-grout leakage effect.

[0008] Preferably, the outer side of the mounting bracket is provided with a guide groove, and the outer side of the movable seat is slidably connected to the inner side of the guide groove.

[0009] By adopting the above technical solution, the guide groove can restrict and guide the movement trajectory of the moving seat, prevent the moving seat from deviating when it rotates with the lead screw, and ensure that the moving seat drives the docking block to accurately dock with the L-shaped connecting block.

[0010] Preferably, a connecting shaft is rotatably connected to the inner side of the mounting bracket, one end of the connecting shaft is fixedly connected to one end of the lead screw, a worm gear is fixedly connected to the outer side of the connecting shaft, and a worm is meshed with the outer side of the worm gear.

[0011] By adopting the above technical solution, the deceleration characteristics of the worm gear and worm meshing transmission are utilized to reduce the force required to adjust the lead screw, making it easier for operators to control the tension of the tensioning component with less effort. At the same time, the self-locking characteristics of the worm gear and worm transmission can prevent the lead screw from rotating on its own without external force, ensuring the stability of the moving seat position.

[0012] Preferably, two support seats are fixedly connected to the outer side of the mounting bracket, and the two ends of the worm are rotatably connected to the inner side of the support seats. A rotating wheel is rotatably connected to the inner side of one of the worms, and the rotation of the rotating wheel is fixedly connected to one end of the worm.

[0013] By adopting the above technical solution, the support base supports and fixes both ends of the worm, ensuring the stability of the worm during rotation, preventing worm wobbling from affecting the meshing accuracy with the worm wheel, and ensuring the reliability of the screw rotation adjustment.

[0014] Preferably, a positioning rod is fixedly connected to one side of each of the multiple sets of building formwork bodies, and a positioning hole is opened on the other side of each of the multiple sets of building formwork bodies, with the outer side of the positioning rod inserted into the inner wall of the positioning hole.

[0015] By adopting the above technical solution, the positioning rod and the positioning hole cooperate to pre-position when multiple sets of building templates are inserted and spliced, ensuring that the insertion rod can be accurately inserted into the slot.

[0016] Preferably, each of the multiple sets of building template bodies has a receiving cavity on its outer side, and a supporting telescopic plate is hinged to the inner side of each receiving cavity. A fastening bolt is installed on the outer side of the fixed end of the supporting telescopic plate.

[0017] By adopting the above technical solution, the accommodating cavity provides storage space for the support telescopic plate, making it convenient to store the support telescopic plate when not in use, reducing space occupation. At the same time, the support telescopic plate can adjust its telescopic length according to the template installation requirements. After extending, it plays an auxiliary supporting role for the main body of the building template, enhancing the overall structural stability of the main body of the building template.

[0018] Preferably, a connecting seat is fixedly connected to the upper side of each of the grounding plates, and the telescopic end of the supporting telescopic plate is installed on the inner side of the connecting seat.

[0019] By adopting the above technical solution, the connecting seat can connect the telescopic end of the support telescopic plate to the grounding plate, so that the support telescopic plate can form a stable connection with the grounding plate, and transfer the force of the main body of the building formwork to the grounding plate and the ground, thereby enhancing the auxiliary support effect of the support telescopic plate on the main body of the building formwork.

[0020] Preferably, a connecting bolt is provided on the inner side of the connecting seat, and the outer side of the connecting bolt is inserted into the inner side of the connecting seat and the inner side of the telescopic end of the supporting telescopic plate. The telescopic end of the supporting telescopic plate and the connecting seat are fixedly connected by the connecting bolt.

[0021] By adopting the above technical solution, the connecting bolts firmly fix the telescopic end of the support telescopic plate to the connecting seat, preventing the support telescopic plate and the connecting seat from loosening or separating during the use of the formwork, and ensuring that the support telescopic plate provides continuous and stable support to the main body of the building formwork.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] This modular building formwork structure, through the use of slots and insert rods, enables rapid splicing of the main body of the building formwork. Simultaneously, the sealing gasket inside the slot directly fills the potential gap between the two, blocking the leakage channel of concrete slurry at the source. The positioning rod and positioning hole then pre-calibrate the splicing position of adjacent building formwork bodies, ensuring precise insertion of the insert rod into the slot and further reducing gaps. Subsequently, the tensioning component and L-shaped connecting block work together, with the lead screw driving the moving seat to stably align the connecting block with the L-shaped connecting block. The connection is further strengthened by bolts, enhancing the tightness of the connection between adjacent building formwork bodies. The meshing characteristics of the worm gear and worm reduce the adjustment force and achieve self-locking, preventing the lead screw from rotating and causing loosening at the connection. Finally, the grounding plate is fixed to the ground with grounding bolts, and the supporting telescopic plate, fixed by the connecting seat and connecting bolts, provides auxiliary support for the main body of the building formwork, improving the overall structural stability, preventing formwork displacement from damaging the seal, and ensuring the quality of concrete component molding.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0032] Example 1: A modular building formwork structure, referring to... Figure 1 , Figure 3 and Figure 4The system includes multiple sets of formwork bodies 1. Each set of formwork bodies 1 has two slots 2 on its outer side. A sealing gasket 3 is fixedly connected to the inner side of each slot 2. A rod 4 is fixedly connected to the other side of each set of formwork bodies 1, with the outer side of the rod 4 inserted into the inner side of the slot 2. The cooperation between the slot 2 and the rod 4 allows for quick splicing of the multiple sets of formwork bodies 1. The sealing gasket 3 inside the slot 2 fills the potential gap between the rod 4 and the slot 2, directly blocking the channel for concrete grout to seep out from the joint, preventing leakage. L-shaped connecting blocks 5 are fixedly connected to the outer side of each set of formwork bodies 1. A tensioning assembly 6 is provided on the outer side of each set of formwork bodies 1. The tensioning assembly 6 includes a mounting bracket 601 fixedly connected to the outer side of the formwork body 1.

A mating block 604 is fixedly connected to the outer side of the movable seat 603. The outer side of the L-shaped connecting block 5... The side is inserted into the inner side of the mating block 604. The mating block 604 and the L-shaped connecting block 5 are fixedly connected by bolts. Utilizing the cooperation between the L-shaped connecting block 5 and the tensioning assembly 6, the screw 602 drives the moving seat 603 to move, thereby driving the L-shaped connecting block 5 to move, further enhancing the tightness of the connection between adjacent building formwork bodies 1, reducing loosening at the connection caused by concrete vibration, and indirectly reducing the risk of grout leakage. The inner side of the mounting frame 601 is rotatably connected to a connecting shaft 606, one end of which is fixed... A worm gear 607 is fixedly connected to one end of the lead screw 602, and a worm 609 is meshed with the outer side of the connecting shaft 606. By utilizing the deceleration characteristics of the meshing transmission between the worm gear 607 and the worm 609, the force required to adjust the lead screw 602 is reduced, making it easier for the operator to control the tension of the tensioning assembly 6 with less effort. At the same time, the self-locking characteristics of the transmission between the worm gear 607 and the worm 609 can prevent the lead screw 602 from rotating on its own without the action of external force, ensuring the stability of the position of the moving seat 603.

[0033] Reference Figure 1 , Figure 2 and Figure 5 Each set of building formwork body 1 has a hinge seat 9 fixedly connected to its outer side. Each hinge seat 9 has a grounding plate 10 hinged to its inner side. Each grounding plate 10 has multiple grounding bolts 11 installed on its outer side. The hinge seat 9 supports the grounding plate 10. The grounding plate 10 is fixed to the ground through the grounding bolts 11, which improves the installation stability of the entire formwork structure, prevents the overall formwork from shifting and damaging the sealing state of the connection, and helps to ensure the anti-leakage effect. Each set of building formwork body 1 has a positioning rod 7 fixedly connected to one side. Each set of building formwork body 1 has a positioning hole 8 on its other side. The outer side of the positioning rod 7 is inserted into the inner wall of the positioning hole 8.

[0034] Example 2: A modular building formwork structure, referring to... Figure 3 and Figure 4 The mounting bracket 601 has a guide groove 605 on its outer side. The outer side of the movable seat 603 is slidably connected to the inner side of the guide groove 605. The guide groove 605 can restrict and guide the movement trajectory of the movable seat 603, preventing the movable seat 603 from deviating when rotating with the lead screw 602, and ensuring that the movable seat 603 drives the docking block 604 to accurately dock with the L-shaped connecting block 5. Two support seats 608 are fixedly connected to the outer side of the mounting bracket 601. The two ends of the worm 609 are rotatably connected to the inner side of the support seat 608. One of the worm 609 has a rotating wheel 610 rotatably connected to the inner side of the wheel 610. The rotation of the rotating wheel 610 is fixedly connected to one end of the worm 609. The support seat 608 supports and fixes the two ends of the worm 609, ensuring the stability of the worm 609 during rotation, avoiding the worm 609 shaking and affecting the meshing accuracy with the worm wheel 607, and ensuring the reliability of the rotation adjustment of the lead screw 602.

[0035] Reference Figure 1 and Figure 5 Each set of building formwork bodies 1 has a receiving cavity 13 on its outer side. A supporting telescopic plate 14 is hinged to the inner side of each receiving cavity 13. Fastening bolts are installed on the outer side of the fixed end of the supporting telescopic plate 14. The receiving cavity 13 provides storage space for the supporting telescopic plate 14, facilitating its storage when not in use and reducing space occupation. Simultaneously, the supporting telescopic plate 14 can adjust its telescopic length according to the formwork installation requirements. When extended, it provides auxiliary support to the building formwork body 1, enhancing the overall structural stability of the building formwork body 1. A connecting seat 12 is fixedly connected to the upper side of each grounding plate 10. The telescopic end of the supporting telescopic plate 14 is installed inside the connecting seat 12, allowing the telescopic end of the supporting telescopic plate 14 to connect with the grounding plate 10. The connection allows the support expansion plate 14 to form a stable connection with the grounding plate 10, transferring the force of the building formwork body 1 to the grounding plate 10 and the ground, enhancing the auxiliary support effect of the support expansion plate 14 on the building formwork body 1. The inner side of the connecting seat 12 is provided with connecting bolts 15, and the outer side of the connecting bolts 15 is inserted into the inner side of the connecting seat 12 and the inner side of the expansion end of the support expansion plate 14. The expansion end of the support expansion plate 14 and the connecting seat 12 are fixedly connected by the connecting bolts 15. The connecting bolts 15 firmly fix the expansion end of the support expansion plate 14 to the connecting seat 12, preventing the support expansion plate 14 and the connecting seat 12 from loosening or separating during the use of the formwork, and ensuring that the support expansion plate 14 provides continuous and stable support for the building formwork body 1.

[0036] The implementation principle of this application embodiment is as follows: First, insert the rod 4 on one side of the adjacent building formwork body 1 into the slot 2 on the other side, and simultaneously insert the positioning rod 7 into the positioning hole 8 to complete the initial positioning and insertion. At this time, the sealing gasket 3 in the slot 2 tightly fits the rod 4, initially blocking the leakage channel of concrete slurry. Then, the operator rotates the rotating wheel 610, which drives the worm gear 609 to rotate. At this time, the worm gear 609 meshes with the worm wheel 607 for transmission. The worm wheel 607 drives the lead screw 602 to rotate on the mounting frame 601 through the connecting shaft 606. The lead screw 602 drives the moving seat 603 to move along the guide groove 605, so that the docking block 604 on the moving seat 603 and the L of the adjacent building formwork body 1 are connected. The L-shaped connecting blocks 5 are precisely aligned, and then the connecting block 604 is fixed to the L-shaped connecting block 5 with bolts. The tensioning force of the tensioning component 6 is used to further tighten the connection between adjacent building formwork bodies 1, reducing gaps caused by concrete vibration. Next, the grounding plate 10 is rotated to fit against the ground, and the grounding plate 10 is fixed to the ground with the grounding bolt 11 to improve the overall installation stability of the formwork. Finally, the support telescopic plate 14 is rotated out from the receiving cavity 13, its telescopic length is adjusted and fixed with fastening bolts, and then the telescopic end of the support telescopic plate 14 is fixed to the connecting seat 12 on the grounding plate 10 with the connecting bolt 15 to form auxiliary support for the building formwork body 1 and enhance the formwork's resistance to deformation.
