[0002] Concrete composite frames are a beam-column system used in structural engineering, in which the beams are composite beams, combining the advantages of precast and cast-in-place concrete to improve structural performance and construction efficiency.

[0003] Publication No. CN217379270U discloses a connection structure between a cast-in-place concrete frame beam and a precast concrete composite floor slab. The structure includes a cast-in-place concrete frame, with pre-embedded reinforcing bars symmetrically arranged inside the second positioning groove. A supporting rib is provided on the upper front side of the cast-in-place concrete frame. A precast concrete composite floor slab is installed on the upper side of the cast-in-place concrete frame via the first and second positioning grooves. First transition blocks are provided at both ends of the lower side of the precast concrete composite floor slab, and a second transition block is provided on the lower side of the precast concrete composite floor slab and inside the first transition blocks. This device uses pre-embedded reinforcing bars and fixing screws, then aligns and installs it with the concrete frame. However, the actual operation is difficult and time-consuming, hindering rapid production. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing devices involve pre-embedding reinforcing bars and fixing screws, then aligning them with a concrete steel frame. However, this method is difficult to implement and requires a significant amount of time during alignment, hindering rapid production. Therefore, this invention proposes a stable alignment structure for a composite steel-concrete frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a steel-concrete composite frame stable alignment structure, comprising a concrete frame assembly, an alignment component installed on the upper end of the concrete frame assembly, and a floor slab assembly provided on the alignment component. The concrete frame assembly includes a cast-in-place concrete frame with an installation groove. The alignment component includes a base, which is fixedly installed in the installation groove.

The upper end of the fixing column extends through the fixing frame to one side, and a nut A is threadedly connected to the upper end of the fixing column. The fixing frame is fixedly installed on the upper surface of the base by the nut A. The floor slab assembly includes a precast floor slab. A reinforcing rib A is fixedly connected inside the precast floor slab. Reinforcing ribs B are symmetrically arranged on the outer side of the reinforcing rib A. Both sets of reinforcing ribs B are fixedly connected inside the precast floor slab, and both reinforcing ribs A and B are placed in the placement groove.

[0006] Preferably, the cast-in-place concrete frame is internally fixed with reinforcing bars, and reinforcing bars are welded between every two sets of reinforcing bars;

[0007] It is used to increase the connection between reinforcing bars and increase the overall strength of the cast-in-place concrete frame.

[0008] Preferably, the lower end of the base is fixedly connected to multiple sets of connecting plates, and the connecting plates are inclined relative to the base;

[0009] This is used to increase the contact area between the base and the cast-in-place concrete frame, while also increasing the connection between the cast-in-place concrete frame and the base.

[0010] Preferably, the base is provided in two sets, and the inner surface of both sets of bases is fixedly connected with a support plate, and the lower surface of the precast floor slab is in contact with the support plate;

[0011] Used to provide some support for precast floor slabs.

[0014] Preferably, both ends of the reinforcing rib A are provided with threaded grooves, and nuts B are threadedly connected to the outer surface of the threaded grooves;

[0015] Used to increase the stability between floor slab components and alignment components.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention proposes a stable alignment structure for a steel-concrete composite frame. By setting an alignment component, the placement groove opened on the base is a V-shaped groove. The precast floor slab is first placed on the base and then fixed by a fixing frame, which makes it easier to place and fix the precast floor slab on the base.

[0018] 2. The present invention proposes a stable alignment structure for a steel-concrete composite frame. By setting up a floor slab assembly, threaded grooves are opened at both ends of the reinforcing bar A, and the reinforcing bar A is fixed to the base and the fixing frame by nuts B, making it more secure.
