The assembled reinforced concrete frame is one of the main fields in the development of building structures in China, which is beneficial to the development trend of building industrialization in China, improves work efficiency, saves resources, develops low-carbon and environmentally friendly buildings, and is also beneficial to improving and ensuring the building quality.

[0003] For example, an assembled concrete precast component splicing structure with the publication number of CN217782562U can realize the connection between components through structures such as a groove body, a connecting plate, and steel bars.

[0004] However, this assembled concrete precast component splicing structure cannot realize the angle adjustment between components, and new concrete precast components need to be rebuilt, consuming more resource costs. Moreover, the connecting parts are exposed outside and are easily corroded by rainwater, etc. Not only that, in terms of pouring, this structure needs to be poured several times, with low efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide an assembled concrete precast splicing component to solve the problems of inability to adjust the angle between components, easy corrosion of exposed connecting parts, and low pouring efficiency mentioned in the above background technique.

[0006] To achieve the above object, the utility model provides the following technical solutions: An assembled concrete precast splicing member, comprising: a first concrete precast member, a first connecting arm, a first pipe orifice, a pouring pipe and a second concrete precast member. At the upper and lower ends on one side of the first concrete precast member, the first connecting arm is fixedly installed. In the middle of the first connecting arm, there is a first pipe orifice. At one end of the first connecting arm, there is a dropping channel. In the middle on one side of the first concrete precast member, there are steel bars. On the upper surface of the first concrete precast member, there are threaded holes. On the outer surface of the first concrete precast member, there are threaded holes. At the upper and lower ends on one side of the second concrete precast member, there are second connecting arms. At one end of the second connecting arm, there is a second pipe orifice. In the middle of the second connecting arm, there is a first stopper. On the lower surface of the first stopper, there is a second stopper. On one side of the second stopper, there is a spring. At the upper and lower ends on one side of the second concrete precast member, there are rotating shafts. Inside one end of the second connecting arm, there is a chute. On both sides and the upper end of the pouring joint between the first concrete precast member and the second concrete precast member, there are baffles. On the upper surface of the baffles, there are nuts. Inside the pouring joint between the first concrete precast member and the second concrete precast member, there is a pouring pipe. At the upper end of the pouring pipe, there is a pouring port.

[0007] Preferably, the diameters of the first pipe orifice and the second pipe orifice are the same. The diameter of the dropping channel is larger than the maximum distance between both sides of the first stopper. The diameter of the first pipe orifice is larger than the diameter of the pouring pipe.

[0008] By adopting the above technical solutions, the automatic clamping of the first connecting arm and the second connecting arm is realized, and a channel for sliding connection with the pouring pipe is formed.

[0009] Preferably, the overall shape of the steel bars is C-shaped. The first stopper and the second stopper are in sliding connection. The first stopper and the second connecting arm are in sliding connection. The second stopper and the chute are in sliding connection.

[0010] By adopting the above technical solutions, the operation of the automatic clamping structure is ensured, and the overall C-shaped steel bars ensure the strength of the structure.

[0012] By adopting the above technical solutions, the angle adjustment between components is realized. After pouring is completed, the pouring port can be removed, so that the pouring pipe remains in the pouring wall body, strengthening the overall strength of the wall body.

[0013] Preferably, the surface of the pouring pipe is evenly distributed with holes of the same diameter. The baffle is provided with holes with a diameter larger than the diameter of the pouring pipe, and the centers of the holes provided in the upper baffle coincide with the centers of the holes of the first pipe orifice and the second pipe orifice.

[0014] Adopting the above technical solution ensures the progress of the pouring process.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the prefabricated concrete assembled splicing member:

[0016] 1. Insert the first connecting arm into the chute provided on the second connecting arm. As the first connecting arm moves, the second stopper is pushed until the first stopper falls into the dropping channel. At this time, due to the blockage of the first stopper, the clamping effect between the first connecting arm and the second connecting arm is achieved, thus completing the automatic connection between the first connecting arm and the second connecting arm. When the angle needs to be adjusted, just rotate the second concrete precast member. The rotational connection between the first connecting arm and the rotating shaft ensures the operation of this structure;

[0017] 2. Since the connecting component will be sealed into the wall after pouring, it isolates the connecting component from contact with the outside world, thus avoiding the erosion of substances such as rainwater, extending the service life of the wall, and the C-shaped steel bars enhance the connection between the components, ensuring the strength of the overall structure;

[0018] 3. Before pouring, fix the corresponding baffles on both sides and the upper end of the place to be poured. Insert the pouring pipe through the hole diameter provided on the upper baffle, then install the pouring port at the upper end of the pouring pipe, and then pour from the pouring port. After pouring, remove the pouring port, and the pouring pipe remains in the poured wall. This not only completes the integral pouring, improves the pouring efficiency, but also the pouring pipe remaining in the wall can play a role in strengthening the structure.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-5, the utility model provides a technical solution: an assembled concrete prefabricated splicing member, including a first concrete prefabricated member 1, a first connecting arm 2, a first pipe opening 3, a dropping channel 4, steel bars 5, threaded holes 6, a second connecting arm 7, a second pipe opening 8, a first stopper 9, a second stopper 10, a spring 11, a rotating shaft 12, a sliding groove 13, a baffle 14, a nut 15, a pouring port 16, a pouring pipe 17 and a second concrete prefabricated member 18. At the upper and lower ends on one side of the first concrete prefabricated member 1, the first connecting arm 2 is fixedly installed. In the middle of the first connecting arm 2, there is the first pipe opening 3. At one end of the first connecting arm 2, there is the dropping channel 4. In the middle on one side of the first concrete prefabricated member 1, there are steel bars 5. On the upper surface of the first concrete prefabricated member 1, there are threaded holes 6. On the outer surface of the first concrete prefabricated member 1, there are threaded holes 6. At the upper and lower ends on one side of the second concrete prefabricated member 18, there are second connecting arms 7. At one end of the second connecting arm 7, there is the second pipe opening 8. In the middle of the second connecting arm 7, there is the first stopper 9. On the lower surface of the first stopper 9, there is the second stopper 10. On one side of the second stopper 10, there is the spring 11. At the upper and lower ends on one side of the second concrete prefabricated member 18, there are rotating shafts 12. Inside one end of the second connecting arm 7, there is a sliding groove 13. The apertures of the first pipe opening 3 and the second pipe opening 8 are the same. The aperture of the dropping channel 4 is larger than the maximum distance between the two sides of the first stopper 9. The aperture of the first pipe opening 3 is larger than the diameter of the pouring pipe 17. The steel bars 5 are in a C shape as a whole. The first stopper 9 and the second stopper 10 are in a sliding connection. The first stopper 9 and the second connecting arm 7 are in a sliding connection. The second stopper 10 and the sliding groove 13 are in a sliding connection. Push the first concrete prefabricated member 1, and due to the movement of the first concrete prefabricated member 1, the first connecting arm 2 is inserted into the sliding groove 13 inside the second connecting arm 7 provided on the second concrete prefabricated member 18. When the first connecting arm 2 pushes the second stopper 10 until the first stopper 9 drops into the dropping channel 4, stop pushing. Due to the blockage of the first stopper 9, the clamping effect between the first connecting arm 2 and the second connecting arm 7 is realized. When it is necessary to release the clamping, just pull out the first stopper 9. The second stopper 10 rebounds to the initial position due to the action of the spring 11. When it is necessary to adjust the angle between the first concrete prefabricated member 1 and the second concrete prefabricated member 18, rotate the second concrete prefabricated member 18. Since the second connecting arm 7 and the rotating shaft 12 are in a rotating connection, and since the second connecting arm 7 and the first connecting arm 2 are clamped, rotating the second concrete prefabricated member 18 can complete the angle adjustment.

[0027] On both sides and the upper end of the pouring joint of the first precast concrete member 1 and the second precast concrete member 18, there are baffles 14. On the upper surface of the baffles 14, there are nuts 15. Inside the pouring joint of the first precast concrete member 1 and the second precast concrete member 18, there is a pouring pipe 17. At the upper end of the pouring pipe 17, there is a pouring port 16. The second connecting arm 7 is rotatably connected to the rotating shaft 12. The lower end surface of the pouring port 16 has threads, and the upper end surface of the pouring pipe 17 has threads. The pouring port 16 and the pouring pipe 17 are threadedly connected. The surface of the pouring pipe 17 is evenly distributed with holes of the same diameter. The baffles 14 have holes with a diameter larger than that of the pouring pipe 17, and the centers of the holes in the upper baffle 14 coincide with the centers of the holes of the first pipe opening 3 and the second pipe opening 8. Before pouring, the corresponding baffles 14 are fixed on both sides and the upper end of the place to be poured through the action of the nuts 15 and the threaded holes 6. The pouring pipe 17 is placed through the hole diameter provided in the upper baffle 14. Since the center of the hole diameter provided in the upper baffle 14 is on the same straight line as the centers of the hole diameters of the first pipe opening 3 and the second pipe opening 8, the pouring pipe 17 can be placed in the path formed by the hole diameter provided in the upper baffle 14 and the first pipe opening 3 and the second pipe opening 8, so that the position of the pouring pipe 17 is fixed, enabling better pouring, ensuring the pouring effect. Subsequently, the pouring port 16 is installed at the upper end of the pouring pipe 17, and then pouring is carried out from the pouring port 16. The slurry flows out from the holes of the same diameter evenly distributed on the surface of the pouring pipe 17. After pouring is completed, the pouring port 16 is removed, and the pouring pipe 17 remains in the pouring wall. Subsequently, the nut 15 is unscrewed and the baffle 14 is removed. Not only is the integral pouring completed, improving the pouring efficiency, but the pouring pipe 17 remaining in the wall can also play a role in strengthening the structure. After pouring is completed, the connecting components will be sealed into the wall, isolating the connecting components from the outside, thus avoiding the erosion of substances such as rainwater and extending the service life of the wall. Moreover, the C-shaped steel bars 5 enhance the connection between the components, ensuring the strength of the overall structure.

[0028] Working principle: When using this prefabricated concrete precast splicing component, by realizing the automatic connection between components, integral pouring, and angle adjustment between components, the efficiency is increased and the cost is saved, thereby increasing the overall practicality.
