Description

Technical Field

[0001] This utility model relates to a prefabricated joint connection component for prefabricated steel frame concrete structure, belonging to the field of prefabricated building technology. Background Technology

[0002] Prefabricated steel frame structure is a building structure that uses steel as the main structural material, prefabricates or processes components in a factory according to design requirements, and assembles and connects them. It mainly includes steel columns, steel beams, steel column bases, wind braces, roof and exterior wall insulation and decoration materials. Compared with traditional concrete frame structure, prefabricated steel frame structure has the advantages of fast construction speed, short construction period, controllable quality, and can be reused and recycled after dismantling. Therefore, a prefabricated component for joint connection of prefabricated steel frame concrete structure is proposed.

[0003] The existing Chinese utility model patent with publication number CN216640900U discloses a prefabricated prestressed concrete frame beam-column press-fit joint, belonging to the field of prefabricated building technology. This technical solution includes a precast concrete frame column, a precast concrete frame beam, prestressed steel strands, and precision-rolled threaded steel bars. The prestressed concrete frame column is vertically continuous, with precast concrete frame beams on both sides. Joint grouting is poured at the joint between the precast concrete frame column and the precast concrete frame beam, and prestressed steel strands and precision-rolled threaded steel bars are threaded through both. The prestressed steel strands and precision-rolled threaded steel bars are tensioned and anchored at both ends, and together with the joint grouting, connect the precast concrete frame column and the precast concrete frame beam into a single unit. This utility model involves triple reinforcement between the precast concrete frame column and the precast concrete frame beam through joint grouting, prestressed steel strands, and precision-rolled threaded steel bars, creating a "strong node, weak component" structural form at the beam-column connection joint, greatly improving the overall integrity and seismic performance of the beam-column connection joint.

[0004] Based on the aforementioned patents and the findings of existing equipment, it has been discovered that because the steel bars cannot be completely butted and fixed during connection, the connection points of the steel bars are prone to misalignment when subjected to vibration. Furthermore, after the steel bars are butted, grout needs to be injected into them, but the grout is prone to overflowing from the connection points, which not only wastes the grout but also results in incomplete grout injection. These problems all affect the use of the device. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a prefabricated component for the joint connection of a prefabricated steel frame concrete structure.

[0006] The technical solution provided by this utility model is as follows: A precast joint connection component for a prefabricated steel frame concrete structure, characterized in that it includes a precast upper column and a precast lower column, both of which are equipped with a steel bar fixing mechanism. The precast upper column and the precast lower column are respectively connected to the longitudinal upper steel bar and the longitudinal lower steel bar through the steel bar fixing mechanism, and the longitudinal upper steel bar and the longitudinal lower steel bar correspond one-to-one. A device sleeve mechanism is connected between the precast upper column and the precast lower column, and the device sleeve mechanism includes a connecting sleeve installed between the precast upper column and the precast lower column. The connecting sleeve is the same size as the precast upper and lower columns. The connecting sleeve has several reinforcing sleeves inside, and the longitudinal upper and lower reinforcing bars are inserted inside the reinforcing sleeves. The upper and lower ends of the connecting sleeve are connected to the sleeve rings. The sleeve rings have several evenly distributed insertion holes. The upper and lower sides of the connecting sleeve are provided with mounting rings. The mounting rings have several insertion posts corresponding to the insertion holes inserted inside. The mounting rings are connected to the sleeve rings through the insertion posts and insertion holes. The upper mounting ring is installed at the lower end of the precast upper column, and the lower mounting ring is installed at the upper end of the precast lower column.

[0007] Furthermore, the steel bar fixing mechanism includes several through-tubes, and connecting rods are connected between the through-tubes. The through-tubes in the precast upper section column are connected to the precast upper section column through the connecting rods. The through-tubes in the precast upper section column have longitudinally inserted upper steel bars. The through-tubes in the precast lower section column are connected to the precast lower section column through the connecting rods. The through-tubes in the precast lower section column have longitudinally inserted lower steel bars.

[0008] The beneficial effects of this utility model are as follows: 1. This utility model provides a connecting sleeve between the precast upper and lower columns. Both ends of the connecting sleeve are provided with sleeve rings and mounting rings. The mounting ring is located at one end of the precast upper and lower columns and is fixedly installed inside the through hole through the through column, so that the mounting ring and the connecting sleeve are fixedly connected. Furthermore, the connecting sleeve and the precast upper and lower columns are the same size, so that the equipment can be seamlessly connected. This utility model can fix the equipment together and also ensure that the grout is filled, thereby increasing the strength between the reinforcing bars.

[0009] 2. This utility model provides reinforcing bar inserts inside both the precast upper and lower columns. The longitudinal upper and lower reinforcing bars are inserted into these inserts, which are then fixedly connected to the precast upper and lower columns via connecting rods. This fixes the position of the reinforcing bars. Furthermore, a retaining sleeve is installed inside the connecting sleeve to fix the connection points of the longitudinal upper and lower reinforcing bars, ensuring alignment, strengthening the connection between the reinforcing bars, and preventing breakage at the connection points due to vibration.
