Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a connection structure for prefabricated floor slabs and prefabricated beams. Background Art

[0002] Prefabricated buildings shift much of the traditional on-site construction work to the factory. Components and accessories are manufactured in the factory, then transported to the construction site for assembly and installation using reliable connections. Prefabricated beams and floor slabs often require assembly. Currently, these connections are typically made using a dry connection with embedded bolts, followed by concrete pouring for reinforcement. However, dry connections relying solely on embedded bolts are not only fragile but also prone to loosening and lack strength. Summary of the Invention

[0003] In view of this, an object of the present invention is to provide a connection structure between a prefabricated floor slab and a prefabricated beam.

[0004] The connection structure between prefabricated floor slabs and prefabricated beams provided by the utility model adopts the following technical solutions:

[0005] A prefabricated floor slab and prefabricated beam connection structure includes a prefabricated slab, a prefabricated beam and a cast-in-place layer. The prefabricated slab is arranged at a position close to both sides of the top of the prefabricated beam. A plurality of connecting bars are arranged in the prefabricated beam. The connecting bars extend upward into the cast-in-place layer and are connected to the transverse bars in the cast-in-place layer.

[0006] Furthermore, the connecting reinforcement is arranged in a U shape in the precast beam and its two ends extend upward to be connected with the transverse reinforcement in the cast-in-place layer.

[0007] Furthermore, the transverse reinforcement in the prefabricated beam is fixed on the two inner corners of the bottom of the connecting reinforcement.

[0008] Furthermore, the end portion of the connecting reinforcement extending into the cast-in-situ layer is bent and provided with a reinforcement hook, and the reinforcement hook bypasses the transverse reinforcement in the cast-in-situ layer and is fixedly connected to the transverse reinforcement.

[0009] Furthermore, a groove is provided in the middle of the top of the precast beam, the precast panels are provided on both sides of the groove, the connecting ribs pass through both sides of the groove, and the cast-in-place layer fills the groove.

[0010] Furthermore, prefabricated ears for supporting the prefabricated panels are provided on both sides of the top of the prefabricated beam.

[0011] In summary, the present invention has at least one of the following beneficial effects: the precast beams and the cast-in-place layer are strengthened and connected by connecting ribs, so that the connection between the precast floor slabs and the precast beams is more stable, and the possibility of loosening between the precast floor slabs and the precast beams can be reduced.

[0015] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention.

[0016] The following is combined with Figure 1 The utility model is described in further detail.

[0017] The embodiment of the utility model discloses a connection structure between a prefabricated floor slab and a prefabricated beam. Figure 1 The connection structure between the precast floor slab and the precast beam includes a precast slab 1, a precast beam 2 and a cast-in-place layer 3. The precast slab 1 is arranged at a position near both sides of the top of the precast beam 2. A plurality of connecting bars 21 are arranged in the precast beam 2. The connecting bars 21 extend upward into the cast-in-place layer 3 and are connected to the transverse bars in the cast-in-place layer 3. Before pouring the cast-in-place layer 3, the connecting bars 21 are welded and fixed to the transverse bars at the position of the cast-in-place layer. When pouring the cast-in-place layer 3, the connecting bars 21 can be fixedly connected to the transverse bars in the cast-in-place layer 3, which can increase the stability of the connection between the cast-in-place layer 3 and the precast beam 2. The connection between the precast beam 3 and the cast-in-place layer 3 is strengthened by the connecting bars 21, so that the connection between the precast floor slab and the precast beam 2 is more stable, which can reduce the possibility of loosening between the precast floor slab and the precast beam 2.

[0018] In this embodiment, the connecting ribs 21 are arranged in a U-shape in the precast beam 2 and both ends extend upward to connect with the transverse ribs in the cast-in-place layer 3 . The U-shaped connecting ribs 21 are more stable in the precast beam 2 .

[0019] In this embodiment, the transverse reinforcement in the prefabricated beam 2 is fixed on the two inner corners of the bottom of the connecting reinforcement 21 . The transverse reinforcement in the prefabricated beam 2 can reinforce the connecting reinforcement 21 .

[0020] In this embodiment, the end portion of the connecting rib 21 extending into the cast-in-place layer 3 is bent and provided with a reinforcing hook 22. The reinforcing hook 22 bypasses the transverse reinforcement in the cast-in-place layer 3 and is fixedly connected to the transverse reinforcement. The reinforcing hook 22 hooks the transverse reinforcement in the cast-in-place layer 3 and is then welded and fixed, thereby strengthening the connection stability between the connecting rib 21 and the transverse reinforcement.

[0021] In this embodiment, a groove is provided in the middle position of the top of the precast beam 2, the precast panel 1 is provided on both sides of the groove, the connecting ribs 21 pass through both sides of the groove, and the cast-in-place layer 3 fills the groove. The cast-in-place layer 3 fills the groove, so that the center of the cast-in-place layer 3 is in the groove at the top of the precast beam 2, making the cast-in-place layer 3 more firm on the precast beam 2.

[0022] In this embodiment, prefabricated ears 23 for supporting the prefabricated panel 1 are provided on both sides of the top of the prefabricated beam 2 .

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting.
