[0033] like Figure 1 and Figure 2 As shown: This utility model provides a beam-slab connection device 1, which has a cavity 14 inside. The lower surface of the beam-slab connection device 1 has multiple first connection holes 11; the side surface of the beam-slab connection device 1 has multiple second connection holes 12; and the upper surface of the beam-slab connection device 1 has multiple third connection holes 13. The first connection holes 11 correspond one-to-one with the vertical connection through holes 21 on the beam 2, the second connection holes 12 correspond one-to-one with the second connection screw holes 41 on the end face of the floor slab 4, and the third connection holes 13 correspond one-to-one with the first connection screw holes 31 on the end face of the wall panel 3.

[0034] Specifically, the third connecting hole 13 is used for the connecting steel bar 32 at the lower end of the wall panel 3 to pass through. The plurality of third connecting holes 13 are arranged linearly along the axis of the beam-slab connecting device 1. The width of the third connecting hole 13 is greater than the diameter of the connecting steel bar 32, and the length of the third connecting hole 13 is greater than the horizontal length of the connecting steel bar 32. In this embodiment, the third connecting hole is rectangular, which facilitates the subsequent pouring of concrete into the cavity 14 through the third connecting hole 13, and also facilitates the subsequent passage of the "L"-shaped connecting steel bar 32.

[0035] Specifically, the plurality of first connecting holes 11 are arranged horizontally in a linear fashion, and each first connecting hole 11 is slotted, with its diameter in the horizontal direction (x-direction) being larger than its diameter in the vertical direction (y-direction) (similar to an ellipse). The plurality of second connecting holes 12 are arranged linearly along the axial direction of the beam-plate connecting device, and each second connecting hole 12 is slotted, with its diameter along the axial direction of the beam-plate connecting device being larger than its diameter along the axial direction of the vertical plate connecting device. Specifically, considering deviations in processing position and size, the diameters of the first connecting holes 11 and the second connecting holes 12 are between those of the bolt shank and nut; in this embodiment, both the first connecting holes 11 and the second connecting holes 12 are slotted. Example

[0036] Please see Figures 3-7 This utility model also provides a beam-slab connection structure, including a beam-slab connection device 1 as described in Embodiment 1, and further including a crossbeam 2, a wall panel 3, a floor slab 4, a first bolt 5, a second bolt 6, and a connecting steel bar 32. A vertically drilled connecting through hole 21 is provided on the crossbeam 2; first connecting screw holes 31 are provided at both ends of the wall panel 3; second connecting screw holes 41 are provided at both ends of the floor slab 4; the first bolt 5 passes through the first connecting hole 11 and the connecting through hole 21 in sequence and is screwed into the first connecting screw hole 31 at the upper end of the wall panel 3; the second bolt 6 passes through the second connecting hole 12 and is screwed into the second connecting screw hole 41; one end of the connecting steel bar 32 is inserted into the first connecting screw hole 31 at the lower end of the wall panel 3, and the other end of the connecting steel bar 32 passes through the third connecting hole 13 and extends into the cavity 14 of the beam-slab connection device 1, the cavity 14 containing concrete. The first bolt 5 can be used to directly lock the upper ends of the beam-slab connection device 1, the crossbeam 2 and the wall panel 3. The second bolt 6 can be used to lock the two ends of the floor slab 4 to the beam-slab connection device 1. The connecting steel bar 32 can be used to fix the lower end of the wall panel 3 to the beam-slab connection device 1, so that the upper and lower ends of the wall panel 3, the crossbeam 2 and the two ends of the floor slab 4 are tightly connected by the beam-slab connection device 1 to form an integral structure with high connection strength and rigidity and good stability.

[0037] Specifically, the connecting steel bar 32 is L-shaped, so that as many connecting steel bars 32 as possible can be placed in the limited cavity 14 volume of the beam-slab connecting device 1, further improving the connection strength between the connecting steel bar 32 and the beam-slab connecting device 1; furthermore, in order to facilitate the connection between the connecting steel bar 32 and the wall panel 3, the vertical end of the connecting steel bar 32 is provided with a thread that matches the first connecting screw hole 31.

[0038] Specifically, the wall panel 3 has a first fitting protrusion 34 on one side and a first fitting groove 35 on the other side. The first fitting protrusion 34 and the first fitting groove 35 match each other. By connecting multiple wall panels 3 on the same floor end to end, they can be spliced ​​together to form a whole wall surface. This not only improves the tightness of the connection between the wall panels 3, but also improves their wind and rain resistance performance, and can also prevent microorganisms or insects such as ants from growing in the gaps and damaging the wall panels 3.

[0039] Specifically, the floor slab 4 has a second fitting protrusion 42 on one side and a second fitting groove 43 on the other side. The second fitting protrusion 42 and the second fitting groove 43 match each other. By connecting multiple floor slabs 4 on the same floor end to end, they can be spliced ​​together to form a whole floor slab 4, which effectively improves the tightness between floor slabs 4 and also improves the load-bearing capacity of the floor slab 4.

[0040] It is worth noting that, in this embodiment, the beam 2, wall panel 3, and floor slab 4 used in this utility model can be the applicant's prior patent application "A bamboo-based composite structure building profile", patent application number "202420921921.0"; and patent "A round bamboo composite beam and column, node connection device and its building frame structure", patent application number "2024226753529"; but it is not limited to the structural features proposed in the above patent applications, and all prefabricated building profiles on the market are within the protection scope of this utility model.

[0041] Specific construction and installation steps:

[0042] Step 1: After the beams and columns of the frame structure are installed, the first bolt 5 is passed through the first connecting hole 11 and the connecting through hole 21 of the crossbeam 2 in sequence, and screwed into the first connecting screw hole 31 at the upper end of the wall panel 3 at the lower part of the crossbeam 2.

[0043] Step 2: Pass the second bolt 6 through the second connecting hole 12 and screw it into the second connecting screw hole 41 on the end face of the floor slab 4;

[0044] Step 3: Before installing the wall panel 3 above the beam 2, pour concrete into the groove formed by the beam 2 and the floor slabs 4 on both sides (where the beam-slab connection device 1 is placed) to fill the groove completely and slightly exceed the floor slab surface. When only one side is connected to the floor slab 4, an auxiliary formwork should be installed on the other side to form a groove for concrete pouring.

[0045] Step 4: When the upper wall panel 3 of the crossbeam 2 is installed, one end of the connecting steel bar 32 is screwed into the first connecting screw hole 31 at the lower end of the wall panel 3, and the other end of the connecting steel bar 32 passes through the third connecting hole 13 and extends into the cavity of the beam-plate connecting device 1, where concrete is poured.

[0046] During installation, the positions of beam 2, wall panel 3, and floor slab 4 should be within the parameter range required by the design.
