Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a floor slab connection node for prefabricated buildings. Background Technology

[0002] As the construction industry moves towards green and industrialized development, prefabricated buildings are increasingly widely used in modern construction due to their advantages such as high efficiency, energy saving, and environmental protection. Floor slabs, as a key component of prefabricated buildings, directly affect the overall structural stability, construction efficiency, and safety during later use through the design of their connection nodes. Therefore, developing a reliable and convenient floor slab connection node technology for prefabricated buildings has become an important issue in promoting the high-quality development of prefabricated buildings.

[0003] In existing prefabricated building floor slab connection technologies, common connection methods include welding, bolting, and grouting. Welding uses high temperatures to fuse the connectors with the floor slab steel, forming a strong connection; bolting relies on high-strength bolts to fasten the prefabricated floor slab to the supporting structure; grouting involves injecting high-strength grout into pre-drilled holes or joints in the prefabricated components to achieve connection between components. These connection methods are mainly based on traditional mechanical fastening or material curing principles, and can meet the basic requirements of floor slab connections to a certain extent.

[0004] However, the cumbersome and inefficient installation and disassembly processes in existing prefabricated building floor slab connection technologies are significant challenges. Taking welding connections as an example, welding operations require specialized technicians and equipment, and the high temperatures generated during welding can easily cause component deformation, affecting connection accuracy. While bolted connections are relatively simple, the installation and removal of bolts consume considerable time and manpower, especially in high-altitude environments, where the operation is difficult and carries high safety risks. These problems extend the construction cycle of floor slab connections, increase construction costs, and make it difficult to meet the rapid construction needs of prefabricated buildings. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a floor slab connection node for prefabricated buildings, aiming to improve the problems of cumbersome and inefficient installation and disassembly processes in existing prefabricated building floor slab connection technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a floor slab connection node for prefabricated buildings, including a base, wherein a positioning column is fixedly connected to the inner wall of the base, and an installation component is provided on the inner wall of the positioning column;

[0007] The installation assembly includes a locking block, the outer wall of which is slidably connected to the inner wall of the positioning column.

A movable block is slidably connected to the inner wall of the locking block, and a threaded rod is threadedly connected to the inner wall of the movable block. A bearing sleeve is fixedly connected to one end of the threaded rod, and a knob is fixedly connected to one end of the bearing sleeve.

[0008] Furthermore, a second base is provided on the outer wall of the first base, a fixing ring is fixedly connected to the outer wall of the second base, and a rotating assembly is provided on the inner wall of the first base.

[0009] Furthermore, the rotating assembly includes a connecting rod, the outer wall of which is rotatably connected to the inner wall of the base, a worm gear is fixedly connected to the outer wall of the connecting rod, a worm is rotatably connected to the inner wall of the fixing ring, the worm meshes with the worm gear, and a knob is fixedly connected to one end of the worm.

[0010] Furthermore, both ends of the spring are fixedly connected inside the locking block, and the spring is used to drive the locking block to reset.

[0011] Furthermore, the knob is located below the positioning post, and the knob is used to drive the bearing sleeve to rotate.

[0012] Furthermore, the movable block is disposed on the inner wall of the positioning column, and the movable block is used to drive the card block to move.

[0014] Furthermore, the guide rods are disposed on both sides of the moving block, and the guide rods are used to guide the block.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model greatly improves the convenience and stability of connecting prefabricated building floor slabs. After the base is placed between the floor slabs and the positioning column is inserted into the joint for positioning, simply turn the knob to drive the locking block to quickly lock into the floor slab using the cooperation of the threaded rod and the moving block, thus achieving a stable connection. When releasing the fixation, turn the knob in the opposite direction, and with the assistance of the spring, the locking block can quickly detach from the floor slab.

[0025] 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.

[0026] Reference Figure 1 - Figure 4 The present invention provides an embodiment of a floor slab connection node for a prefabricated building, including a base 1, which is placed between two floor slabs to provide a stable platform for subsequent connection operations. A positioning column 2 is fixedly connected to the inner wall of the base 1. By inserting it into the internal joint of the floor slab, the base 1 and the floor slab are accurately positioned to ensure that the connection node is installed in an accurate position. An installation component is provided on the inner wall of the positioning column 2.

[0027] The installation assembly includes a locking block 5, which, pushed by a movable block 6, overcomes the elastic force of a spring 7 and slides along a guide rod 8 to engage with the floor slab, achieving a secure connection between the floor slabs. When the movable block 6 moves upward, it disengages from the floor slab under the reset action of the spring 7. The outer wall of the locking block 5 is slidably connected to the inner wall of the positioning column 2, and the inner wall of the locking block 5 is slidably connected to the guide rod 8, which provides precise guidance during the sliding process of the locking block 5, ensuring that the locking block 5 accurately engages and disengages from the floor slab in a straight line, preventing the locking block 5 from shifting or jamming. A spring 7 is sleeved on the outer wall of the guide rod 8; when it is necessary to release the floor slab fixation, after the movable block 6 moves upward, the locking block 5 quickly returns to its original position due to its own elasticity. To facilitate subsequent operations, the locking block 5 is designed to detach from the floor slab, ensuring repeated and flexible fixing and disassembly. A movable block 6 is slidably connected to the inner wall of the locking block 5, moving up and down along the threaded rod 4 as it rotates. When moving down, it pushes one end of the locking block 5 against the floor slab to lock it in place. When moving up, it cooperates with the spring 7 to disengage the locking block 5 from the floor slab. A threaded rod 4 is threadedly connected to the inner wall of the movable block 6, and a bearing sleeve 9 is fixedly connected to one end of the threaded rod 4. When the knob 3 is rotated, it provides support and protection for the threaded rod 4, reducing friction during rotation. A knob 3 is fixedly connected to one end of the bearing sleeve 9, which is driven to rotate by manual rotation.

[0028] Specifically, first place the base 1 between the two floor slabs, insert the positioning post 2 into the floor slab joint for positioning, drive the knob 3 to rotate, causing the bearing sleeve 9 and the threaded rod 4 to rotate, the moving block 6 moves down along the threaded rod 4 to abut against the locking block 5, so that it overcomes the elastic force of the spring 7, slides out along the guide rod 8 and locks into the floor slab to complete the fixation, rotate the knob 3 in the opposite direction, the moving block 6 moves up, the spring 7 resets and causes the locking block 5 to disengage from the floor slab, thus achieving disassembly.

[0029] Reference Figure 5The outer wall of base 1 is provided with base 2 15, which can flexibly adjust its angle according to the different floor slab connection requirements of prefabricated buildings. It can adapt to the complex splicing of floor slabs in irregular buildings or the connection of floor slabs with different inclination angles, improving the versatility of connection nodes and the diversity of building structures. The outer wall of base 2 15 is fixedly connected with a fixing ring 11, and the inner wall is rotatably connected with a worm gear 12, providing rotational support and positioning for the worm gear 12, ensuring the stability of the worm gear 12 during rotation, and ensuring accurate meshing between the worm gear 12 and the worm wheel 14. The inner wall of base 11 is provided with a rotating assembly, which includes a connecting rod 10. The outer wall of the connecting rod 10 is rotatably connected to the inner wall of base 11, and the outer wall of the connecting rod 10 is fixedly connected with a worm wheel 14. Under the drive of the worm gear 12, the connecting rod 10 rotates, and because it is fixedly connected to base 2 15, it drives base 2 15 to rotate, thereby realizing angle adjustment and ensuring the stability of the worm gear 12 during rotation. After adjustment, the angle is stable. The inner wall of the fixed ring 11 is rotatably connected to the worm gear 12, which meshes with the worm wheel 14 to transmit the rotation of the knob 13 to the worm wheel 14. The worm gear 12 meshes with the worm wheel 14, and one end of the worm gear 12 is fixedly connected to the knob 13. Manually rotating the knob 13 drives the worm gear 12 to rotate, providing power input for the angle adjustment of the base 15. Both ends of the spring 7 are fixedly connected to the inside of the locking block 5. The spring 7 is used to drive the locking block 5 to reset. The knob 3 is located below the positioning post 2. The knob 3 is used to drive the bearing sleeve 9 to rotate. The moving block 6 is located on the inner wall of the positioning post 2. The moving block 6 is used to drive the locking block 5 to move. The knob 13 is located below the fixed ring 11. The knob 13 is used to drive the worm gear 12 to rotate. The guide rod 8 is located on both sides of the moving block 6. The guide rod 8 is used to guide the locking block 5.

[0030] Specifically, by rotating knob 13, the worm gear 12 is driven to rotate within the fixed ring 11. Through the meshing transmission between the worm gear 12 and the worm wheel 14, the base 15 fixed to the worm wheel 14 is rotated to adapt to different connection requirements. This ensures stability after angle adjustment and achieves precise angle control. Whether it is the complex splicing of floor slabs in irregularly shaped buildings or the connection of floor slabs with different inclination angles, this adjustment method can quickly adapt and effectively improve the construction efficiency and structural diversity of prefabricated buildings.

[0031] Working principle: When the floor slab connection node of the prefabricated building is required, first place the base 1 between the two floor slabs, then insert the positioning column 2 into the joint inside the floor slab for positioning, and then drive the knob 3 to drive the bearing sleeve 9 and the threaded rod 4 to rotate. While the threaded rod 4 is rotating, the moving block 6 moves up and down along the threaded rod 4. When the moving block 6 moves down, it will abut against one end of the locking block 5, so that the locking block 5 is locked into the floor slab and fixed to the floor slab. When it is necessary to release the fixing between the floor slabs, simply turn the knob 3 in the opposite direction to drive the moving block 6 to move upward. With the reset of the spring 7, the locking block 5 can be released from the floor slab.

[0032] In addition, rotating knob 13 will drive worm 12 to rotate. Simultaneously, the meshing relationship between worm 12 and worm wheel 14 will drive worm wheel 14 to rotate. Worm wheel 14 is fixedly connected to base 15, and finally drives base 15 to rotate. The angle of base 15 can be adjusted to adapt to different connection requirements.

[0033] 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.
