Description
Technical Field
[0001] The utility model relates to the field of precast concrete, and particularly relates to an assembled concrete connecting member. Background Art
[0002] An assembled building is a building form in which some or all of the components that make up the building are processed in a factory and then transported to the construction site, where the prefabricated components are assembled in place through a reliable connection method. In the daily construction process of assembled buildings, how to connect two precast concrete assembled wall panels is still a key link. In traditional technologies, the main connection method between precast concrete assembled wall panels is wet connection. However, wet connection has inevitable disadvantages. For example, the arrangement of steel bars is relatively complex, and high requirements are imposed on the technical level and proficiency of workers. The curing of concrete during the wet connection process is also greatly affected by weather and climate. In the shear wall structure, the sleeve grouting material has high requirements for construction temperature, etc., which restricts the development of assembly. Therefore, connection through connecting members has gradually gained favor. However, when using connecting members for connection, it is more necessary to ensure the fastening degree of the connection and the convenience of connection. Therefore, it is necessary to provide a concrete connecting member that is convenient and fast to connect and at the same time has stable connection. Summary of the Utility Model
[0003] The utility model aims to provide an assembled concrete connecting member to provide a concrete connecting member that is convenient and fast to connect and at the same time has stable connection.
[0004] To achieve the above purpose, the utility model adopts the following technical scheme: An assembled concrete connecting member includes a plurality of concrete components and a connecting mechanism. The connecting mechanism includes a first connecting portion and a second connecting portion. The first connecting portion includes a steel member embedded inside the concrete component, and at least one support rod is fixed to the end of the steel member. The second connecting portion includes a connecting plate embedded in another concrete component, and the end of the steel member can be fixedly connected to the connecting plate.
[0005] The beneficial effects of this solution are as follows:
[0006] The steel member of the first connecting portion is embedded inside the concrete component, and support rods are arranged at the end. The steel member and the support rods form a framework inside the concrete, increasing the structural strength of the concrete component and at the same time being integrated with the concrete component. The connecting plate of the second connecting portion is fixedly connected to the end of the steel member, ensuring that the connection between two adjacent concrete components has sufficient strength and stability. Compared with the traditional wet connection method, this technical solution reduces the complexity of steel bar arrangement, and at the same time ensures the structural strength of the concrete component. Through standardized connecting members, it can be accurately manufactured in the factory and quickly assembled on site, improving the assembly accuracy and consistency and accelerating the construction progress of the wall surface.
[0007] Preferably, as an improvement, an embedded box is fixed on the connecting plate. Connecting holes are formed on the connecting plate and the embedded box, and the end of the steel member can pass through the connecting hole and enter the embedded box.
[0008] The beneficial effects are as follows: The embedded box can accommodate the end of the steel member. If the two concrete components need to be disassembled later after the steel member is fixedly connected, the connection can be released in the embedded box. On the other hand, it can effectively prevent the end of the steel member from being exposed to the external environment, reduce the physical damage or corrosion of the steel member, and extend the service life of the connection part.
[0009] Preferably, as an improvement, it further includes a plurality of nuts threadedly connected to the end of the steel member. After the steel member is connected to the connecting plate, one nut is distributed on both sides of the connecting plate.
[0010] The beneficial effects are as follows: After the steel member is connected to the connecting plate, one nut is distributed on both sides of the connecting plate. The height or surface levelness of the upper concrete component can be fine-tuned by adjusting the position of the bottom nut to support the connecting plate; the threaded connection between the nut and the end of the steel member provides a firm mechanical fixation, significantly enhancing the connection strength between the wall panels, ensuring that the two adjacent concrete components can be firmly locked, and thus preventing loosening or displacement caused by external forces during use.
[0011] Preferably, as an improvement, the steel member is a threaded steel bar.
[0012] The beneficial effects are as follows: The surface of the threaded steel bar has threads, which has a stronger bonding force with concrete, thus providing greater uplift resistance and shear resistance, significantly enhancing the firmness of the connection. The threaded steel bar forms a strong anchoring point at the connection part, which can effectively resist the action of vibration or other dynamic loads; on the other hand, when the threaded steel bar is threadedly connected to the nut, it can be automatically aligned and locked, and construction workers can quickly complete the installation without complex adjustments.
[0013] Preferably, as an improvement, rib steel embedded in the concrete component is also fixed on the connecting plate.
[0014] The beneficial effects are as follows: Through the above settings, the structural strength of the concrete component can be increased while ensuring the connection strength between the connecting plate and the concrete component.
[0015] Preferably, as an improvement, the rib steel is U-shaped, and both ends of the rib steel are welded and fixed to the connecting plate.
[0016] The beneficial effects are as follows: The U-shaped rib steel has a larger contact surface area with the concrete component, and the bonding force between the concrete and the rib steel is stronger, which helps to better transfer and disperse the load, thereby further improving the stability and durability of the connection.
[0017] Preferably, as an improvement, a reinforcing layer is also coated at the joint between concrete components.
[0018] The beneficial effect is that the reinforcing layer can effectively increase the bonding strength of the joint, making the two concrete components form a more compact whole after connection, and avoiding cracking or loosening during use.
[0019] Preferably, as an improvement, at least one installation groove is opened on the concrete component equipped with steel members, and the steel members are all arranged in the installation groove.
[0020] Preferably, as an improvement, a convex block matching the installation groove is arranged on the surface of the concrete component connected to the concrete component provided with steel members.
[0021] The beneficial effect is that the convex block can be inserted into the installation groove for alignment, facilitating the connection and assembly between two adjacent concrete components, improving the accuracy of the connection position at the same time. Construction workers do not need to repeatedly adjust the position of the components during assembly, thus accelerating the assembly speed; at the same time, the contact area at the joint is larger and the friction force is greater, preventing sliding or displacement between the concrete components after installation, and thus ensuring the stability of the entire wall structure.

[0023] Figure 2 is a schematic structural diagram of Embodiment 2 of the present utility model. Detailed Description of the Invention
[0024] The following is a further detailed description through specific embodiments:
[0025] The reference numerals in the drawings of the specification include: concrete component 1, support rod 2, connecting plate 3, gasket 4, installation groove 5, embedded box 6, nut 7, steel member 8, rib steel 9, steel backing plate 10, convex block 11.
[0026] Embodiment 1
[0027] Embodiment 1 is basically as Figure 1 shown, as Figure 1An assembled concrete connection member shown in the figure includes a plurality of concrete components 1 and a connection mechanism. The connection mechanism includes a first connection part and a second connection part. The first connection part includes a steel member 8 embedded inside the concrete component 1. At least one support rod 2 is fixed to the end of the steel member 8. In this embodiment, the number of support rods 2 is two. The support rods 2 are welded or clamped to the steel member 8. The second connection part includes a connection plate 3 embedded in another concrete component 1. The end of the steel member 8 can be fixedly connected to the connection plate 3. It also includes a plurality of nuts 7 threadedly connected to the end of the steel member 8. After the steel member 8 is connected to the connection plate 3, one nut 7 is distributed on both sides of the connection plate. As Figure 1 shown, it also includes a steel backing plate 10 and a gasket 4 distributed on the connection plate 3. The steel backing plate 10 and the gasket 4 are both slidably sleeved on the steel member 8 and are limited by the nut 7, which improves the support effect at the connection between the steel member 8 and the connection plate 3. After the steel member 8 is connected to the connection plate 3, one nut 7 is distributed on both sides of the connection plate 3. The height or surface levelness of the upper concrete component 1 can be adjusted by finely adjusting the position of the bottom nut 7 to support the connection plate 3. The nut 7 is threadedly connected to the end of the steel member 8, which enhances the connection strength between the wall panels and ensures that the two adjacent concrete components 1 can be firmly locked; a buried box 6 is fixed on the connection plate 3. Connection holes are opened on the connection plate 3 and the buried box 6. The end of the steel member 8 can pass through the connection hole and enter the buried box 6. The buried box 6 can accommodate the end of the steel member 8. If it is necessary to disassemble the two concrete components 1 later after fixedly connecting the steel member 8, the connection can be released in the buried box 6, which is convenient for later demolition and reuse of the concrete components. On the other hand, it can effectively prevent the end of the steel member 8 from being exposed to the external environment, reduce the physical damage or corrosion of the steel member 8, and extend the service life of the connection part. In this embodiment, the steel member 8 is a threaded steel rod, and the surface of the threaded steel rod has threads, which has a stronger bonding force with the concrete component and thus provides greater uplift force and shear resistance, significantly improving the firmness of the connection.
[0028] A rib steel 9 embedded in the concrete component 1 is also fixed on the connection plate 3. The rib steel 9 is U-shaped, and both ends of the rib steel 9 are welded and fixed to the connection plate 3. The contact surface area between the U-shaped rib steel 9 and the concrete component 1 is relatively large, and the bonding force between the concrete and the rib steel 9 is stronger, which helps to better transfer and disperse the load, thereby further improving the stability and durability of the connection; in this embodiment, a strengthening layer is also coated at the connection between the concrete components 1. The strengthening layer can effectively increase the bonding strength at the connection, making the two concrete components 1 form a more compact whole after connection and avoiding cracking or loosening during use.
[0029] At least one installation groove 5 is opened on the concrete component 1 equipped with the steel member 8, and the steel member 8 is arranged at the installation groove 5. The installation groove 5 provides a sliding space for the up and down fine adjustment of the nut 7 below.
[0030] The specific implementation process is as follows:
[0031] The steel member 8 of the first connecting part is embedded inside the concrete component 1, and a strut 2 is arranged at the end. The steel member 8 and the strut 2 form a framework inside the concrete, increasing the structural strength of the concrete component 1 and being integrally connected with the concrete component 1 at the same time. The connecting plate 3 of the second connecting part is fixedly connected to the end of the steel member 8, ensuring that the connection between two adjacent concrete components 1 has sufficient strength and stability. Compared with the traditional wet connection method, this technical solution reduces the complexity of steel bar arrangement, and also ensures the structural strength of the concrete component 1. Through standardized connecting components, it can be accurately manufactured in the factory and quickly assembled on site, improving the assembly accuracy and consistency, and accelerating the construction progress of the wall surface.
[0032] Embodiment 2
[0033] Embodiment 2 is as Figure 2 shown. The difference from Embodiment 1 is that a convex block 11 matching with the installation groove 5 is provided on the surface of the concrete component 8 connected to the concrete component provided with the steel member 8. The convex block 11 can be inserted into the installation groove 5 and the height of the convex block 11 is less than the depth of the installation groove 5. In this embodiment, the steel member 8 is arranged in the installation groove 5; the convex block 11 can be inserted into the installation groove 5 for alignment, facilitating the connection and assembly between two adjacent concrete components 1. After assembly, the gap is filled with concrete, improving the accuracy of the connection position and the flatness of the wall surface. Construction workers do not need to repeatedly adjust the position of the components during assembly, thus accelerating the assembly speed; at the same time, the contact area at the connection is larger and the friction force is greater, preventing sliding or displacement between the concrete components 1 after installation, thus ensuring the stability of the entire wall structure. In this embodiment, the steel member 8 is arranged in the installation groove 5, facilitating the connection of the steel member 8 through the connecting plate 3 while docking the installation groove 5 with the convex block 11, which helps to ensure the connection efficiency and connection accuracy.
