Description

[Technical Field]

[0001] This utility model belongs to the field of curtain wall structure technology, and in particular relates to a steel beam composite floor slab curtain wall support connection system. [Background Technology]

[0002] Currently, the common practice for connecting steel beam composite floor slab curtain wall supports is to first pour the concrete floor slab, then excavate the concrete at the curtain wall support connection point to expose the steel beam structure, and finally connect the curtain wall structure to the steel beam structure using hanger bases. This method damages the connection between the concrete and the steel beam structure, leaving a pit at every curtain wall support connection point. Before backfilling with concrete, the reinforcing steel bars must be re-tied, making the process complicated and inefficient. [Utility Model Content]

[0003] The purpose of this utility model is to provide a steel beam composite floor slab curtain wall support connection system that simplifies the process and improves construction efficiency.

[0004] This utility model is achieved by the following technical solution:

[0005] A steel beam composite floor slab curtain wall support connection system includes:

[0006] An embedded steel column is provided, with one end connected to the steel beam structure and the other end having a connecting bolt hole. At least two of the embedded steel columns are arranged along a straight line.

[0007] A positioning plate having at least two first mounting holes corresponding to the connecting screw holes;

[0008] A mounting base for installing a curtain wall structure, wherein the mounting base is provided with at least two second mounting holes corresponding to the connecting screw holes;

[0009] The connecting bolts can pass through the first mounting hole and engage with the connecting screw hole to connect the embedded steel column and the positioning plate, or they can pass through the second mounting hole and engage with the connecting screw hole to connect the embedded steel column and the hanger base, so as to connect the steel beam structure and the curtain wall structure.

[0010] As described above, a steel beam composite floor slab curtain wall support connection system includes a base plate and a hook portion located at one end of the base plate and extending upward. A first connecting groove is formed between the hook portion and the base plate. The curtain wall structure includes a curtain wall connector and a limiting bolt. The curtain wall connector is provided with a second connecting groove that matches the shape of the hook portion and allows the hook portion to extend into it. When the hook portion extends into the second connecting groove, the limiting bolt can pass through the curtain wall connector and extend into the first connecting groove to cooperate with the second connecting groove to connect the base plate and the curtain wall connector.

[0011] As described above, in a steel beam composite floor slab curtain wall support connection system, the base plate is provided with a first corrugated connection surface.

[0012] As described above, in a steel beam composite floor slab curtain wall support connection system, the first corrugated connection surface is inclined downward at the end away from the hook.

[0013] As described above, a steel beam composite floor slab curtain wall support connection system is provided between the base plate and the connecting bolts. The connecting plate has a second corrugated connecting surface that is inclined and matches the first corrugated connecting surface on the side near the first corrugated connecting surface, and a connecting plane on the side of the connecting plate away from the first corrugated connecting surface.

[0014] As described above, in a steel beam composite floor slab curtain wall support connection system, the pre-embedded steel column is welded to the steel beam structure.

[0015] As described above, in a steel beam composite floor slab curtain wall support connection system, the connecting bolts are made of stainless steel.

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

[0017] This utility model provides a steel beam composite floor slab curtain wall support connection system, including a pre-embedded steel column with connecting screw holes, a positioning plate with at least two first mounting holes corresponding to the connecting screw holes, a hanger base with at least two second mounting holes corresponding to the connecting screw holes, and connecting bolts. During construction, the pre-embedded steel column is first fixed to the positioning plate by the connecting bolts to achieve precise positioning of multiple pre-embedded steel columns. The pre-embedded steel column is then connected to the steel beam structure before concrete is poured. After the pouring is completed, the positioning plate is removed, exposing the connecting screw holes of the pre-embedded steel column. The hanger base is then connected to the pre-embedded steel column by the connecting bolts engaging with the exposed connecting screw holes. The curtain wall structure is then installed through the hanger base to achieve the connection between the steel beam structure and the curtain wall structure. This eliminates the need to excavate concrete during the installation of the hanger base, and also eliminates the need to re-tie reinforcing bars and backfill concrete, simplifying the process and increasing construction efficiency.

The connection is compact, stable, and easy to assemble and disassemble.

[0027] In addition, the base plate 31 is provided with a first corrugated connecting surface 7.
