Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a prefabricated component steel reinforcement connection structure. Background Technology

[0002] Precast concrete components are widely used in the current trend of prefabricated building construction. They are formed by pre-tying steel bars, pouring concrete to form a slab structure, and transporting it to the construction site for assembly, which greatly improves the construction speed. During the assembly process, the steel bars of two adjacent components that extend beyond the ends of the components need to be connected together by welding or mechanical connection to form a joint force between the slabs, so as to ensure the structural safety of the building structure.

[0003] For example, Chinese utility model patent application number 202123011104.7 discloses a precast component steel reinforcement connection structure. Its structural features include a first elongated hole and a second elongated hole, each with a first elongated slot and a second elongated slot, respectively. The first and second elongated hole components are arranged opposite each other, with the first and second elongated slots perpendicular to each other, and are connected. This utility model's precast component steel reinforcement connection structure, by providing two oppositely arranged and perpendicular elongated hole components, offers ample tolerance for the installation of embedded parts through the elongated slots, resulting in a large tolerance in both perpendicular directions for similar dimensions.

[0004] Although the device in the aforementioned patent provides tolerance for the installation of embedded parts, making the connection structure highly tolerant in both perpendicular directions when the dimensions are similar, in actual use, when there is an inclination error at the connection point of the two embedded parts, it is impossible to connect the embedded parts, thus reducing the applicability of the device.

[0030] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0031] According to one embodiment of the present invention, in conjunction with Figure 1-4 As shown. A precast component steel bar connection structure includes: two embedded parts 1, each embedded part 1 having a connecting steel bar 2 and an outer frame 3. Four fixing rods 7 are fixedly connected between opposite sides of the two outer frames 3. An annular block 4 is provided inside the outer frame 3, and four fixing blocks 9 are fixedly connected inside the outer frame 3, with each fixing block 9 fixedly connected to the outer surface of the annular block 4. An annular plate 5 is provided inside the annular block 4, and a connecting groove 6 is formed on the annular plate 5. The end of the connecting steel bar 2 away from the embedded part 1 extends movably into the connecting groove 6. The connecting steel bar 2 is connected to the annular plate 6 by a fastening nut 8. The plate 5 is fixedly connected, and the annular block 4 is equipped with connecting components and fixing components. Through the coordinated use of the pre-embedded parts 1, outer frame 3, annular block 4, annular plate 5, fixing rod 7, connecting groove 6, fastening nut 8, annular groove 10, rotating groove 11, rotating block 12, mounting block 13 and fastener 14, the angle of use of the connecting groove 6 can be adjusted according to the position of the two connecting steel bars 2, so that it can connect the two connecting steel bars 2 that are tilted and misaligned after pre-embedding. It is also suitable for connecting the connecting steel bars 2 that are misaligned vertically and horizontally after pre-embedding, thereby improving the applicability of the device.

[0032] In this embodiment, an annular groove 10 is provided inside the annular block 4, and the annular plate 5 is adapted to the annular groove 10. The connecting component includes a rotating groove 11 and a rotating block 12. The rotating groove 11 is opened inside the annular groove 10, and the rotating block 12 is rotatably connected inside the rotating groove 11. The rotating block 12 is fixedly connected to the annular plate 5. By setting the connecting component, the annular plate 5 can be rotated and limited to prevent it from moving horizontally during rotation.

[0033] In this embodiment, the fixing component includes two mounting blocks 13, both of which are fixedly connected to one side of the annular plate 5. Both mounting blocks 13 are arc-shaped and are provided with fasteners 14. Both mounting blocks 13 are threadedly connected to the fasteners 14. The outer surface of the fasteners 14 is provided with several anti-slip grooves 15. By setting the fixing component, the annular plate 5 can be fixed and limited to prevent it from rotating during use. At the same time, it avoids hindering the installation of the fastening nut 8, so that the fastening nut 8 can still be installed when the connecting steel bar 2 is inside one end of the connecting groove 6, thereby improving the practicality of the device.

[0034] Working principle: When using the device, if there is an installation error after the two embedded parts 1 are installed, causing the two connecting steel bars 2 to tilt and misalign, one of the connecting grooves 6 is connected to the connecting steel bar 2 during connection. The two outer frames 3 are moved to one side. According to the position of the other connecting steel bar 2, the corresponding connecting groove 6 is adjusted. The fasteners 14 on the corresponding outer frame 3 are rotated so that they are no longer firmly abutting against the corresponding annular block 4. After separating it from the two mounting blocks 13, the rotation limit on the corresponding annular plate 5 is released, and the annular plate 5 can be rotated. Under the cooperation of the corresponding annular groove 10, rotating groove 11 and rotating block 12, the annular plate 5 drives the connecting groove 6 to rotate, thereby adjusting its operating angle. After rotating it to the corresponding angle, the two outer frames 3 are moved, and the other connecting steel bar 2 is inserted into the adjusted connecting groove 6. Then the fasteners 14 are reset to fix the annular plate 5. Two fastening nuts 8 are used to connect the two connecting steel bars 2 to the corresponding annular plate 5 respectively, completing the connection of the two embedded parts 1.

[0035] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
