[0002] In the field of construction, the efficiency of construction can be improved by manufacturing prefabricated parts. Prefabricated parts are various building accessories such as floor slabs, stairs, and beams that are prefabricated with concrete and then assembled at the construction site. This method can greatly shorten the construction period of buildings. Moreover, during prefabrication, discarded concrete blocks can be used as recycled materials and fine aggregates of concrete after being crushed, screened, and processed, thereby realizing resource recycling and reuse. This type of concrete is also called recycled concrete.

[0003] In the prior art, many precast concrete parts are also made by splicing and assembling various parts, such as a reinforced concrete precast component with publication number CN112211287B, in which two vertical components are combined and connected by plugging and grouting.

[0004] After the upper and lower components are connected end to end, concrete is poured into the cavity between the two components. However, the fluidity of recycled concrete is poor. After the recycled concrete enters the cavity, the flow of the recycled concrete cannot be promoted from the outside, and thus it is impossible to ensure that the cavity is fully poured with recycled concrete. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a recycled concrete prefabricated component and a manufacturing process, which utilizes the elastic force of a spring to push a filling rod to hit a pin body, causing the pin body to vibrate inside the lower cavity. The vibration of the pin body will affect the recycled concrete poured into the lower cavity, thereby promoting the flow of the recycled concrete, so that the recycled concrete can be more fully filled in the lower cavity and the upper cavity, thereby effectively solving the problems in the background technology.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1-3 As shown, the utility model provides a recycled concrete prefabricated component, comprising a plurality of prefabricated body parts 1 connected end to end, wherein a lower cavity 8 is formed at the top of the prefabricated body part 1, and an upper cavity 3 is formed at the protruding portion at the bottom of the prefabricated body part 1. When two prefabricated body parts 1 are connected end to end, the protruding portion of the top prefabricated body part 1 is inserted into the lower cavity 8 at the top of the bottom prefabricated body part 1, and the upper cavity 3 is connected to the lower cavity 8.

[0020] Two fixing pins 10 are arranged inside the lower cavity 8. The fixing pins 10 include a pin body 1001. One end of the pin body 1001 extends to the outer end of the preform body 1. The cavity inside the pin body 1001 is filled with a filling rod 1002.

[0021] A spring 1003 and a tension rope 1005 are fixedly disposed at one end of the filling rod 1002 that opens toward the pin body 1001 , a limiting ring 1004 fixedly disposed on the inner wall of the cavity of the pin body 1001 is fixedly disposed at one end of the spring 1003 that is away from the pin body 1001 , and one end of the tension rope 1005 extends to the outside of the pin body 1001 .

[0022] The two prefabricated body parts 1 are aligned end to end, and the protrusion of the top prefabricated body part 1 is inserted into the lower cavity 8 of the bottom prefabricated body part 1, so as to connect the two prefabricated body parts 1 end to end. After the connection, the upper cavity 3 and the lower cavity 8 at the connection part are connected to each other, and concrete is poured into the upper cavity 3 and the lower cavity 8. During the pouring process, the tension rope 1005 is pulled to shrink the spring 1003, and then the tension rope 1005 is released. The elastic force of the spring 1003 will push the filling rod 1002 to hit the pin body 1001, and the pin body 1001 will vibrate inside the lower cavity 8. The vibration of the pin body 1001 will affect the recycled concrete poured into the lower cavity 8, thereby promoting the flow of the recycled concrete, so that the recycled concrete can be more fully filled in the lower cavity 8 and the upper cavity 3.

[0023] In order to make the connection between the two prefabricated bodies 1 more secure, Figure 1As shown, a pouring channel 2 communicating with the interior of the upper cavity 3 is provided at the outer end of the preform body 1, and a plurality of connecting beams 6 are provided inside the upper cavity 3, and the top ends of the connecting beams 6 are fixedly connected to the top preform body 1;

[0024] The bottom end of the connecting beam 6 extends to the interior of the lower cavity 8 , and both sides of the connecting beam 6 are provided with clamping plates 9 fixed on the inner wall of the lower cavity 8 , and the pin body 1001 passes through the connecting beam 6 and the clamping plates 9 , and a plurality of through holes 5 are opened on the connecting beam 6 .

[0025] The connecting beam 6 fixed on the top prefabricated body 1 is inserted into the lower cavity 8 of the bottom prefabricated body 1 during connection, and each connecting beam 6 is clamped between two clamping plates 9. The connecting beam 6 and the clamping plates 9 are connected by a pin 1001, and then the connecting beam 6 is fixed to the bottom prefabricated body 1. After pouring the recycled concrete, the connecting beam 6 is fixed by the solidified recycled concrete, and the through hole 5 makes the connection between the recycled concrete and the connecting beam 6 more complete, thereby strengthening the connection strength between the two prefabricated bodies 1 through the connecting beam 6.

[0026] After pouring the recycled concrete, it is necessary to pressurize the recycled concrete inside the upper cavity 3 and the lower cavity 8, such as Figure 1-3 As shown, the preform body 1 is provided with side grooves 4 on both sides, and the upper cavity 3 is provided with pressurizing components 7 on both sides, and the pressurizing components 7 include fixing plates 701 embedded in the side grooves 4 on the corresponding side;

[0027] A plurality of push rods 702 are fixedly provided on one side of the fixing plate 701 facing the upper cavity 3, and the outer ends of the push rods 702 are sleeved with sleeves embedded in the inner wall of the upper cavity 3. A rubber head 703 located inside the sleeve is fixedly provided on one end of the push rods 702 facing the upper cavity 3, and the outer ends of the rubber heads 703 are fixedly connected to the inner wall of the sleeve.

[0028] Before pouring concrete, the fixing plates 701 are inserted into the sleeves one by one. After pouring, the fixing plates 701 are pushed so that the push rods 702 and the rubber heads 703 penetrate into the sleeves. The push rods 702 and the rubber heads 703 are used to squeeze the concrete to pressurize the concrete. Compared with the prior art, the push rods 702 can play a supporting role while pressurizing, and no cavity will be left inside the prefabricated body 1.
