[0025] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0026] Reference Figures 1 to 3 The invention discloses a quick-connect concrete connection structure, comprising a beam-column connector 1, a beam head 2, and a connecting bolt 3 connecting the beam-column connector 1 and the beam head 2. The beam-column connector 1 comprises a fixing card 11, on which a plug-in 12 perpendicular to the fixing card 11 is arranged, and a first threaded hole 13 is arranged at one end of the plug-in 12 away from the fixing card 11; the beam head 2 comprises a connecting member 21, and a second threaded hole 22 is arranged at one end of the connecting member 21 facing the plug-in 12; the connecting bolt 3 connects the beam-column connector 1 and the beam head 2 together by connecting the first threaded hole 13 and the second threaded hole 22.

[0027] In this embodiment, the beam-column connector 1 is fixed in the beam-column, and the beam-column is used as a support force point. No additional support is required, and it has the characteristics of low requirements for the use environment. The beam head 2 is used to overlap and fix the scaffolding board. This application can be detachably installed, and each part can be disassembled separately. When stored, it can be stored in the form of sheets, and the space utilization rate is high. When in use, its function can be realized after simple assembly.

[0028] In one embodiment, a splay leg 14 is provided on the side of the fixed card 11, and the splay leg 14 is fixedly connected to the fixed card 11. A plurality of splay legs 14 are spread out around the fixed card 11, and a protrusion is provided at one end of the splay leg 14 away from the fixed card 11.

[0029] In this embodiment, the fixing ability of the beam-column connector 1 to the beam-column is enhanced by providing the expansion leg 14, and the expansion leg 14 is used to unload the force to prevent the beam-column connector 1 from causing local damage to the beam-column or even falling off the beam-column when it is subjected to a large gravity.

[0030] In one of the embodiments, a through hole opened along the length direction of the fixed card 11 is provided at the center of the fixed card 11, and the connector 12 is inserted into the first through hole. One end of the connector 12 close to the fixed card 11 protrudes in the length direction of the through hole to form a shoulder, and the distance between the two shoulders is greater than the length of the through hole.

[0031] Furthermore, the beam-column connector 1 further includes a support sheet 4 , two support sheets 4 are welded to the shoulder, and one end of the support sheet 4 close to the fixing card 11 abuts against the fixing card 11 .

[0032] In this embodiment, the fixing card 11 is rectangular, oval or circular in shape, and a through hole is provided in the fixing card 11 for the connector 12 to pass through. At this time, one end of the connector 12 with the first threaded hole 13 passes through the through hole and is connected to the second threaded hole 22. The shoulder formed at the other end of the connector 12 is clamped on the fixing card 11 to limit the length of the connector 12 extending out of the fixing card 11.

[0033] The setting of the support plate 4 can enhance the limiting capacity between the shoulder and the fixed card 11, avoiding the shoulder from deforming and losing its original function during the force-bearing process. The cross-shaped setting of the support plate 4 and the shoulder not only has the aforementioned functions, but also prevents the connector 12 from shaking in the through hole, thereby ensuring the stability of the scaffolding board.

[0034] In one embodiment, the upper and lower end surfaces of the connecting member 21 are respectively provided with storage plates 23 , and the two storage plates 23 and the connecting member 21 form an I-shape. The storage plates 23 are used to carry scaffolding boards to increase the contact area between the scaffolding boards and the storage plates 23 .

[0035] Furthermore, a steel bar 24 is provided on each placement plate 23, and the steel bars 24 are arranged along the length direction of the placement plate 23, and two steel bars 24 are arranged in parallel and spaced apart on both sides of the placement plate 23. The aforementioned beam head 2 also includes a pin 5, which is fixed in the beam column, and the pin 5 is connected to the steel bar 24 through a steel bar sleeve 25. The steel bar 24 can be connected to the steel in the beam through a structure similar to a sleeve. Of course, the steel in the beam can be directly connected to the placement plate 23 to avoid affecting the strength through the sleeve connection.

[0036] In this embodiment, the pin 5, the steel sleeve 25 and the steel bar 24 serve as the second connection scheme of the present application, which further improves the connection safety of the connector 12 and the connector 21.

[0037] In one embodiment, the plurality of first threaded holes 13 and the plurality of second threaded holes 22 are arranged in the same manner, both in a rectangular array. When the first threaded holes 13 are connected to the second threaded holes 22, the rectangle formed by the first threaded holes 13 overlaps with the rectangle formed by the second threaded holes 22.

[0038] In this embodiment, the first threaded holes 13 and the second threaded holes 22 are arranged in a rectangular shape and are connected by connecting bolts 3 , which can effectively enhance the connection strength between the plug-in component 12 and the connector 21 .

[0039] In the present application, the purpose of fixing the scaffolding board by the beam column is achieved by connecting the detachable plug-in connector 12 and the connecting member 21, and the plug-in connector 12 and the connecting member 21 are detachably connected, which is convenient for transportation and storage. The fixing ability of the beam-column connector 1 is enhanced by expanding the branch leg 14, ensuring safety and connection strength. The connection between the pin 5 and the steel bar 24 achieves a double connection guarantee from another perspective, improving the safety level of the present application.

[0040] In addition, the present application can be used in conjunction with multiple quick-connect concrete connection structures to form single-side, opposite-side, L-side, three-side and four-side structures. When multiple quick-connect concrete connection structures are used in conjunction, the support sheet 4 can be adapted to change to facilitate connection with the shoulder. For example, when used on opposite sides, two slots are provided on the two opposite sides of the support sheet 4 to connect with the shoulder, and two quick-connect concrete connection joints share the same support sheet 4. Similarly, when using L-side, three-side and four-side, slots are provided at the corresponding positions of the support sheet 4 to facilitate connection with the shoulders of different quick-connect concrete connection joints.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
