Technical Field
[0001] This utility model relates to the field of building engineering technology, specifically to a novel prefabricated RC frame structure energy-dissipating column base. Background Technology
[0002] Over the past two decades, the construction industry, as a pillar industry of the national economy, has played a pivotal role in national economic development. Prefabricated concrete structures are an important structural form for the industrialization and modernization of building structures. Among them, prefabricated concrete frame systems are the most widely used prefabricated structural systems. Currently, the main assembly methods for prefabricated concrete structures are sleeve grouting connection and grout anchor lap connection, which connect steel bars through sleeves or metal corrugated pipes, etc., both of which are wet connection forms. According to past earthquake damage findings, the main cause of structural collapse is the initial damage at the connection between prefabricated components.
[0003] Currently available prefabricated RC frames cannot secure the reinforcing bars to the interior of the base during use. Consequently, the reinforcing bars may wobble during the pouring process, thus affecting work efficiency.
[0004] Therefore, there is an urgent need for a new type of prefabricated RC frame structure energy-dissipating column base to improve the above problems. Utility Model Content
[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.
[0006] Therefore, one objective of this utility model is to propose a novel prefabricated RC frame structure energy-dissipating column base to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.
[0007] To achieve the above objectives, one embodiment of this utility model provides a novel prefabricated RC frame structure energy-dissipating column base, including a base. The base has an installation hole and a through hole inside. A threaded rod is provided inside the installation hole. A fixing plate and a nut are provided on the outside of the threaded rod. A metal washer is provided on one side of the nut. A fixing plate two is provided on one side of the fixing plate one. The fixing plate one has a connecting hole and a flow groove inside. The fixing plate two has an adapter hole inside. A reinforcing bar is provided inside the connecting hole. A stirrup is provided on the outside of the reinforcing bar. A connecting block is provided at the bottom of the base. A ground beam and a limiting plate are provided on the outside of the connecting block. A limiting rib is provided inside the limiting plate.
[0008] Preferably, the second fixing plate has a connecting hole and a flow groove inside, and the first fixing plate is adapted to the second fixing plate.
[0009] By adopting the above technical solution, fixing plate one and fixing plate two are compatible and play the role of fixing the reinforcing bars.
[0010] Preferably, the threaded rod is fixedly connected to the fixed plate, the metal washer is slidably connected to the outside of the threaded rod, and the nut is adapted to the threaded rod.
[0011] By adopting the above technical solution, the threaded rod is fixedly connected to the fixing plate, thus serving to install the fixing plate.
[0012] Preferably, one end of the reinforcing bar is inserted into the inside of the connecting hole, and the stirrup is inserted into the outside of the reinforcing bar.
[0013] By adopting the above technical solution, one end of the reinforcing bar is inserted into the inside of the connection hole, which serves as a limiting function.
[0014] Preferably, the base and the connecting block are fixedly connected, and the limiting plate is fixedly connected to the outside of the connecting block.
[0015] By adopting the above technical solution, the base and the connecting block are fixedly connected, which serves to fix the base.
[0016] Preferably, the limiting rib is fixedly connected to the inside of the limiting plate, and the connecting block is snapped into the inside of the ground beam.
[0017] By adopting the above technical solution, the limiting rib is fixedly connected to the inside of the limiting plate, which increases the stress-bearing area.
[0018] In summary, the beneficial technical effects of this utility model are as follows:
[0019] This novel prefabricated RC frame structure energy-dissipating column base uses connecting holes and flow grooves inside fixed plate one and fixed plate two to fix the reinforcing bars in conjunction with the installation holes. At the same time, the flow grooves facilitate the encapsulation of the reinforcing bars with concrete. The installation holes and adapter holes facilitate the passage of threaded rods. The use of nuts, metal washers, and threaded rods securely connects fixed plate one, fixed plate two, and the base. The use of connecting blocks, limiting plates, and limiting ribs facilitates the encapsulation of the reinforcing bars with concrete. By using this structure, the bending of the reinforcing bars can be effectively avoided during installation, thereby improving work efficiency. Attached Figure Description

[0026] Reference Figures 1 to 4 This utility model discloses a novel prefabricated RC frame structure energy-dissipating column base, including a base 1. The base 1 has an installation hole 2 and a through hole 3 inside. A threaded rod 4 is installed inside the installation hole 2. A fixing plate 5 and a nut 6 are installed on the outside of the threaded rod 4. A metal washer 7 is installed on one side of the nut 6. A fixing plate 8 is installed on one side of the fixing plate 5. A connecting hole 9 and a flow groove 10 are installed inside the fixing plate 5. An adapter hole 11 is installed inside the fixing plate 8. A reinforcing bar 12 is installed inside the connecting hole 9. A stirrup 13 is installed on the outside of the reinforcing bar 12. A connecting block 14 is installed at the bottom of the base 1. A ground beam 15 and a limiting plate 16 are installed on the outside of the connecting block 14. A limiting rib 17 is installed inside the limiting plate 16. In this embodiment, the base 1 serves as a splicing structure, and the installation hole 2 facilitates the installation of the reinforcing bar 4.
[0027] Reference Figure 1 and Figure 3 The interior of the second fixing plate 8 is provided with a connecting hole 9 and a flow groove 10. The first fixing plate 5 is adapted to the second fixing plate 8. In this embodiment, the second fixing plate 8 plays a limiting role, the connecting hole 9 plays a role in clamping the reinforcing bar 13, and the flow groove 10 plays a role in facilitating the concrete to wrap the reinforcing bar 13.
[0028] Reference Figure 3 The threaded rod 4 is fixedly connected to the fixing plate 5. The metal washer 7 is slidably connected to the outside of the threaded rod 4. The nut 6 is adapted to the threaded rod 4. In this embodiment, the threaded rod 4 serves to install the fixing plate 5, the metal washer 7 serves to reduce friction, the threaded rod 4 serves to limit movement, and the nut 6 serves to fix the threaded rod 4.
[0029] Reference Figure 1 and Figure 3 One end of the reinforcing bar 12 is inserted into the inside of the connecting hole 9, and the stirrup 13 is inserted into the outside of the reinforcing bar 12. In this embodiment, the reinforcing bar 12 plays the role of supporting the construction structure, and the stirrup 13 plays the role of fixing the reinforcing bar 12.
[0030] Reference Figure 2 The base 1 and the connecting block 14 are fixedly connected, and the limiting plate 16 is fixedly connected to the outside of the connecting block 14. In this embodiment, the connecting block 14 is used to soak into the concrete, and the limiting plate 16 is used to increase the bearing area.
[0031] Reference Figure 1 and Figure 2 The limiting rib 17 is fixedly connected to the inside of the limiting plate 16, and the connecting block 14 is snapped into the inside of the ground beam 15. In this embodiment, the limiting rib 17 plays the role of increasing the force-bearing area.
[0032] The working principle of this utility model is as follows:
[0033] During use, the base 1, connecting block 14 and other structures are fixed into the groove of the ground beam 15. When the reinforcing bar 12 is in place, one end of the reinforcing bar 12 is aligned with the through hole 3 and the end of the reinforcing bar 12 is passed through the through hole 3. After the end of the reinforcing bar 12 passes through the through hole 3, it will enter the connecting hole 9 opened by the fixing plate 1 5 and the fixing plate 2 8 until the end of the reinforcing bar 12 is in contact with the base 1. At this time, the tool is used to drive the nut 6 to rotate. During the rotation of the nut 6, the position of the nut 6 remains unchanged, while the threaded rod 4 will slide inside the mounting hole 2 and the adapter hole 11. As the nut 6 rotates continuously, the gap between the fixing plate 1 5 and the fixing plate 2 8 will gradually decrease until the fixing plate 1 5 and the fixing plate 2 8 are in a completely close state, and the reinforcing bar 12 is firmly snapped into the inside of the connecting hole 9.
[0034] After the steel bar 12 is fixed, concrete can be poured into the groove of the ground beam 15. As the concrete continues to enter the groove, it will gradually wrap around the connecting block 14, the limiting plate 16 and the limiting bar 17 until the concrete completely submerges the entire base 1. The workers use a vibrator to vibrate the concrete, which can effectively make the concrete wrap more tightly. At the same time, during the process of adding concrete, the concrete will flow into the interior of the flow channel 10 so that the concrete wraps around the bottom of the steel bar 12. After the concrete solidifies, the ground beam 15 will be formed, and the connecting block 14, the limiting plate 16 and the limiting bar 17 will be snapped into the interior of the concrete ground beam 15 to prevent the base 1 and the steel bar 12 from falling off. Then the construction can be carried out around the steel bar 12.
[0035] Since the shapes of fixing plate 5 and fixing plate 8 are different, the flow groove 10 inside fixing plate 5 is complete, while the flow groove 10 inside fixing plate 8 is incomplete due to the shape of fixing plate 8. However, some of the edges are parallel to the flow groove 10 inside fixing plate 5. At the same time, fixing plate 5 and fixing plate 8 have the same connecting hole 9. The connecting hole 9 of the two plates is used to splice them together to fix the reinforcing bar 12.
[0036] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
