Description

Technical Field

[0001] This utility model relates to the field of building structures, specifically to an RCS assembly of prefabricated concrete columns and steel beams. Background Technology

[0002] Reinforced concrete column-steel beam (RCS) composite structures are a novel structural form, consisting of reinforced concrete columns (RC) and steel beams (S). The RCS composite structure system combines the advantages of both traditional steel (S) and reinforced concrete (RC) structures. Compared to steel columns, reinforced concrete columns have superior lateral stiffness and are more economical to construct. For the beams, steel beams exhibit better deformation performance than concrete beams. Under the beam hinge mechanism, steel beam structures offer stronger seismic resistance, and their construction speed is also faster than that of concrete beams. Compared to ordinary reinforced concrete frame structures, RCS hybrid frame structures offer advantages such as lighter self-weight, larger usable building space, and faster construction speed, while also demonstrating superior performance in stiffness, fire resistance, and durability. Based on these advantages, RCS composite structures have gained significant attention from the engineering community worldwide.

[0003] However, existing RCS composite structures have certain defects in practical use. When connecting and assembling steel beams and concrete columns, connecting plates are mostly fitted on the outside of the concrete columns, and then the steel beams are connected and fixed through the connecting plates. However, there is no good connection method between the connecting plates and the concrete columns. At the same time, the connecting plates and steel beams are mostly fastened with simple screws, which affects the overall connection effect. Under large deformation, the bearing capacity and ductility of the concrete columns in the joint area will decrease. Utility Model Content

[0004] The purpose of this utility model is to provide an RCS assembly of prefabricated concrete columns and steel beams to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fully automatic filling machine includes a concrete column body and a steel beam body. A sleeve plate is fitted on the outside of the concrete column body. Mounting plates are symmetrically provided on both sides of the sleeve plate. The mounting plates are matched with the steel beam body by fastening components. The mounting plates are also provided with an adjustment mechanism that matches the steel beam body.

[0007] Furthermore, in order to facilitate connection with the concrete column body and make it easy to form a whole after subsequent pouring, the sleeve plate has connection holes at equal intervals on its periphery, and the connection holes match the concrete column body.

[0008] Furthermore, in order to ensure that the sleeve plate fits snugly against the concrete column body during pouring, auxiliary grooves are provided at equal intervals on the inner circumferential side of the sleeve plate.

[0009] Furthermore, in order to ensure a secure fastening after connection, the fastening assembly includes a connector that is fixedly connected to the mounting plate. Fastening holes are provided at equal intervals on both the connector and the main body of the steel beam, and fastening screws are threaded into the fastening holes.

[0010] Furthermore, in order to enable initial positioning and fixation after insertion and facilitate subsequent tightening and fixing operations, anti-slip pads are symmetrically provided at both ends of the connector, and the anti-slip pads match the inner wall of the steel beam body.

[0011] Furthermore, in order to ensure a firm connection by tightening the adjusting plate against the main body of the steel beam after insertion, the adjusting mechanism also includes an adjusting plate symmetrically slidably arranged in the middle of the connecting piece. The end of the adjusting plate is provided with an elastic pad that matches the inner wall of the main body of the steel beam. The ends of the two adjusting plates that are close to each other are provided with tapered holes. Adjusting holes are provided in the middle of both the connecting piece and the main body of the steel beam. Adjusting screws are threaded into the adjusting holes, and the tapered holes match the adjusting screws.

[0012] Furthermore, in order to ensure the stability of the adjustment plate when it moves up and down and to avoid deviation, a guide block is fixed on the side wall of the adjustment plate, and a guide groove matching the guide block is opened on the connecting piece.

[0013] Compared with the prior art, the present invention has the following beneficial effects: by casting the sleeve plate inside the concrete column body, it can be connected as a whole after casting, thereby ensuring the strength and firmness of its outer sleeve plate. Furthermore, by using fastening components and adjustment mechanisms, it can be easily connected and fixed to the steel beam body. The connection can be adjusted to make it tightly fixed to the steel beam body, ensuring the strength during connection, thereby enhancing the bearing capacity of the beam-column joint area, improving the ductility of the prefabricated concrete column and steel beam RCS assembly, and thus improving the seismic performance of the prefabricated concrete column and steel beam RCS assembly.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5According to an embodiment of this utility model, an RCS assembly of precast concrete column and steel beam includes a concrete column body 1 (RC), which is shown in the figure as a steel reinforcement hoop before the concrete column body 1 is poured, which facilitates subsequent pouring operations. A sleeve plate 2 is fitted on the outside of the sleeve plate 2. Connection holes 4 are equidistantly opened on the periphery of the sleeve plate 2, which can be easily connected and fixed to the steel reinforcement hoop of the concrete column body 1 by means of wire, so as to facilitate subsequent pouring and integration and ensure the overall firmness. At the same time, an auxiliary groove 6 is opened on the periphery of the inner wall of the sleeve plate 2, which can facilitate the concrete to enter the interior and facilitate adhesion. After pouring, the sleeve plate 2 is located inside the concrete, which ensures the firmness between the formed concrete column body 1 and the sleeve plate 2, and facilitates the subsequent connection of the steel beam body 3 (S) (partial illustration). The two side walls of the sleeve plate 2 are symmetrically welded with mounting plates 5 (located inside the concrete column body 1 after pouring). The mounting plates 5 are fixedly connected to the steel beam body 3 by fastening components and adjustment mechanisms to ensure a firm connection. The fastening components and adjustment components are located outside the poured concrete column body 1 for easy connection and assembly.

[0024] Please see Figures 1-5 To facilitate the assembly and fixation of the steel beam body 3 and ensure its firmness during use, a fastening component connector 7 is welded to the end of the mounting plate 5. Anti-slip pads 8 are symmetrically bonded to both ends of the connector 7 to increase friction when it contacts the steel beam body 3, allowing for initial positioning and fixation. Fastening holes 11 are equidistantly provided on both the connector 7 and the steel beam body 3, with threaded fastening screws 9 engaging within each hole for easy connection and fixation. To further enhance the connection's stability, a sliding groove is provided in the middle of the connector 7, inside which an adjusting plate 12 of an adjusting mechanism slides symmetrically. An elastic gasket 14, which contacts the inner wall of the steel beam body 3, is bonded to the end of the adjusting plate 12. The two adjusting plates 12 have tapered holes 15 at their close ends. The connecting piece 7 and the steel beam body 3 both have adjusting holes 13 in the middle. Adjusting screws 10 are threaded into the adjusting holes 13. The tapered holes 15 match the adjusting screws 10. When the adjusting screws 10 are tightened, they can generate a pushing force that moves the adjusting plates 12 away from each other. This allows the elastic pads 14 on the adjusting plates 12 to fit tightly against the inner wall of the steel beam body 3, ensuring a firm fit. In order to facilitate the up and down movement of the adjusting plates 12 and prevent displacement, guide blocks 16 are welded to the side walls of the adjusting plates 12. The corresponding position of the connecting piece 7 has a guide groove 17 that matches the guide block 16.

[0025] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0026] In summary, with the help of the above-mentioned technical solution of this utility model, when assembling and connecting the steel beam body 3 and the concrete column body 1, the steel beam body 3 can be inserted into the connector 7, and then the anti-slip pad 8 can be used for initial positioning and fixing. By inserting the adjusting screw 10 into the guide adjusting hole 13 and tightening the adjusting screw 10, the tapered hole 15 can generate a pushing force that moves the adjusting plate 12 away from each other during rotation. This allows the elastic pad 14 on the adjusting plate 12 to easily fit and press against the inner wall of the steel beam body 3, ensuring firmness. Then the steel beam body 3 can be fastened and fixed. Finally, the fastening screw 9 and the fastening hole 11 can be used to fix the connector 7 and the steel beam body 3 again, ensuring stability and firmness during use.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
