Description

Technical Field

[0001] This invention relates to a process for manufacturing precast concrete components. Background Technology

[0002] Precast concrete components are building components prefabricated off-site, allowing for direct installation and saving on-site construction time. They also offer superior quality as precast components. The manufacturing process of precast concrete components requires specialized molds. However, most existing molds for precast concrete components are one-piece structures. After the concrete has hardened, it is difficult to remove the precast concrete component from the mold. Therefore, while some existing molds are detachable, they rely solely on bolts and screws for fixing during assembly and disassembly. While simple, this method is cumbersome and significantly reduces work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a manufacturing process for precast concrete components. By improving the mold, the precast concrete component can be easily separated from the mold, making it easier to remove the finished product and improving production efficiency.

[0004] To achieve the above objectives, the technical solution of the present invention is to design a process for manufacturing precast concrete components, including the following steps;

[0005] Step 1: Pre-make a mold. The mold includes a base plate and four side plates movably disposed on the top of the base plate. The four side plates are used to form a rectangular cavity. The four side plates are two first side plates and two second side plates. The two first side plates are arranged opposite each other and can move towards or away from each other. The two second side plates are arranged opposite each other and can move towards or away from each other.

[0006] Step 2: Fix the reinforcing steel components in the rectangular cavity;

[0007] Step 3: Inject an appropriate amount of concrete into the rectangular cavity;

[0008] Step four: After the concrete has solidified, separate the formed precast concrete component from the mold.

[0009] Preferably, the first side plate is equipped with a driving mechanism, which includes a driving hydraulic cylinder and a push-pull plate. The driving hydraulic cylinder is fixed to the top of the base plate, and the push-pull plate is located between the driving hydraulic cylinder and the first side plate.

The end of the push-pull plate is connected to a driving block through a connecting rod, and the driving block is provided with a first inclined surface. The base plate is provided with a sliding groove located outside the second side plate. The sliding groove is provided with a slider and a return spring connected to the slider.

The first side plate is located between the driving block and the transmission block. The transmission block is provided with a second inclined surface for cooperating with the first inclined surface.

[0016] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0017] The specific technical solution of this invention is as follows:

[0018] like Figure 1 and Figure 2 As shown, a process for manufacturing precast concrete components includes the following steps;

[0019] Step 1: Pre-make a mold. The mold includes a base plate 1 and four side plates movably disposed on the top of the base plate 1. The four side plates are used to form a rectangular cavity 100. The four side plates are two first side plates 2 and two second side plates 3. The two first side plates 2 are arranged opposite each other and can move towards or away from each other. The two second side plates 3 are arranged opposite each other and can move towards or away from each other.

[0020] Step 2: Fix the steel reinforcement components in the rectangular cavity 100;

[0021] Step 3: Inject an appropriate amount of concrete into the rectangular cavity 100;

[0022] Step four: After the concrete has solidified, separate the formed precast concrete component from the mold. By adopting the above method, when it is necessary to use a mold to make precast concrete components, the mold, which is in the disassembled state, is first switched to the assembled state. Specifically, the two first side plates 2 are moved into position facing each other, and the two second side plates 3 are moved into position facing each other. At this time, the mold is in the assembled state, and a rectangular cavity 100 is formed between the four side plates. Then, the reinforcing steel component is fixed in the rectangular cavity 100. Next, an appropriate amount of concrete is injected into the rectangular cavity 100. After the concrete has solidified, the two first side plates 2 are moved into position facing away from each other, and the two second side plates 3 are moved into position facing away from each other. At this time, the mold is switched back to the disassembled state, so that the formed precast concrete component can be separated from the mold, which facilitates the removal of the finished product and helps to improve production efficiency.

[0023] Furthermore, the first side plate 2 is equipped with a driving mechanism, which includes a driving hydraulic cylinder 4 and a push-pull plate 5. The driving hydraulic cylinder 4 is fixed to the top of the base plate 1. The push-pull plate 5 is located between the driving hydraulic cylinder 4 and the first side plate 2, and the push-pull plate 5 is fixedly connected to the first side plate 2 through a bracket 6. The output shaft of the driving hydraulic cylinder 4 is fixedly connected to the push-pull plate 5. The end of the push-pull plate 5 is connected to a driving block 8 through a connecting rod 7, and the driving block 8 is provided with a first inclined surface 9. The base plate 1 is provided with a sliding groove 10 located outside the second side plate 3. The sliding groove 10 is provided with a slider 11 and a return spring 12 connected to the slider 11. The slider 11 is fixedly connected to the second side plate 3 through a connecting block 13. The end of the second side plate 3 is provided with a transmission block 14 corresponding to the driving block 8. The first side plate 2 is located between the driving block 8 and the transmission block 14. The transmission block 14 is provided with a second inclined surface 15 for cooperating with the first inclined surface 9. By adopting the above scheme, the output shafts of the two driving hydraulic cylinders 4 are simultaneously extended, thereby driving the two first side plates 2 to move towards each other through the push-pull plate 5 and the bracket 6. During this process, the first side plate 2 will pass over the transmission block 14 and move between the two second side plates 3. The push-pull plate 5 will drive the driving block 8 to move through the connecting rod 7. During the movement of the driving block 8, the first inclined surface 9 on it will contact the second inclined surface 15 on the transmission block 14. Through the contact and cooperation between the first inclined surface 9 and the second inclined surface 15, the corresponding transmission block 14 will move, thereby enabling the two second side plates 3 to move towards each other through their respective connected transmission blocks 14. During the movement of the second side plate 3, the return spring 12 will be stretched by the slider 11 until the output shaft of the driving hydraulic cylinder 4 extends to the position. At this time, the first inclined surface 9 will separate from the second inclined surface 15. At this time, the inner side surface of the second side plate 3 will contact the end of the first side plate 2, and the driving block 8 will abut against the outer side of the transmission block 14 to prevent the second side plate 3 from retreating. At this time, the mold is in the assembly state. After the precast concrete component is made, the output shafts of the two drive hydraulic cylinders 4 are retracted simultaneously, causing the two first side plates 2 to move in opposite directions. During this process, the drive block 8 will separate from the transmission block 14, and the two second side plates 3 will move in opposite directions under the elastic restoring force of their respective connected return springs 12. When the output shafts of the drive hydraulic cylinders 4 are retracted into place, the first side plates 2 and the second side plates 3 are separated from the precast concrete component. At this time, the mold is in the disassembled state, and the finished product can be easily removed.

[0024] Furthermore, the end of the first side plate 2 is provided with a third inclined surface 16, and the transmission block 14 is also provided with a fourth inclined surface 17 for cooperating with the third inclined surface 16. By adopting the above solution, if the second side plate 3 is stuck together with the solidified precast concrete component, when the two first side plates 2 move in opposite directions, the first side plate 2 can drive the corresponding transmission block 14 to move through the contact cooperation of the third inclined surface 16 and the fourth inclined surface 17, thereby forcing the second side plate 3 to move and separate from the precast concrete component. Afterwards, the second side plate 3 will be reset by the return spring 12, thereby ensuring the reliability of the mold disassembly operation.

[0025] Furthermore, the inner surface of the second side plate 3 is provided with a vertical sealing groove corresponding to the end of the first side plate 2. A sealing strip 18 is provided in the vertical sealing groove, and the sealing strip 18 partially protrudes from the inner surface of the second side plate 3. By adopting the above solution, when the mold is in the assembled state, the sealing strip on the second side plate 3 will be tightly attached to the end of the first side plate 2, thereby preventing the concrete injected into the rectangular cavity 100 from flowing out from the gap between the first side plate 2 and the second side plate 3, which is beneficial to improving the quality of the precast concrete components.

[0026] Furthermore, a lifting hole forming head 19 is provided on the inner side of the first side plate 2. By adopting the above solution, a lifting hole is formed on the side of the precast concrete component, so that the precast concrete component can be lifted off the base plate 1 by using lifting equipment in conjunction with the lifting hole.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
