Description

Technical Field

[0001] The present application relates to the technical field of concrete construction, and in particular to a concrete structure construction system and method based on plastic alloy formwork. Background Art

[0002] Plastic alloy formwork offers numerous advantages, including a combination of rigidity and plasticity, high strength, light weight, high impact resistance, on-site secondary processing, and resistance to cold and high temperatures. It is also half the weight of aluminum alloy and is easy to assemble and construct, making it an ideal formwork material for construction projects. After the plastic alloy formwork is installed and calibrated, concrete pouring is required. To improve and adjust the concrete's properties, admixtures are typically added, with the amount of admixture generally not exceeding 5% of the concrete mass.

[0003] Currently, admixtures are added directly to the concrete surface and then mixed in a mixing tank. However, with only single-direction rotational mixing, it's difficult for the admixture to penetrate the concrete bottom, resulting in uneven mixing of the concrete and admixture. Furthermore, this method takes a long time to mix, resulting in low mixing efficiency. Therefore, improvements are needed. Summary of the Invention

[0004] In order to solve the above problems, the embodiments of the present application provide a concrete structure construction system and method based on plastic alloy formwork, which improves the mixing quality of concrete and admixtures and the mixing efficiency of concrete and admixtures.

[0005] In a first aspect, in order to achieve the above-mentioned objectives, the embodiments of the present application specifically adopt the following technical solutions: a concrete structure construction system based on a plastic alloy formwork, comprising a mixing tank, a mixing unit, and a feeding unit, wherein the mixing tank is provided with a feeding port and a discharging port, the mixing unit comprises a rotating tube, a driving member, and a plurality of branch tubes, the rotating tube is rotatably connected to the feeding unit, the feeding unit is used to introduce an admixture into the rotating tube, the rotating tube and the mixing tank are coaxially arranged, the driving member is used to drive the rotating tube to rotate, the branch tubes are connected to the rotating tube, and the branch tubes are provided with a plurality of injection units;

[0006] The injection unit includes a connecting pipe, a cover plate, a penetration component and a spring. The connecting pipe is connected to the branch pipe. The cover plate and the penetration component are connected to each other and are slidably embedded in the connecting pipe. The penetration component allows the additive in the connecting pipe to seep out of the connecting pipe, and the penetration component is connected to the connecting pipe through a spring. When the spring is in a natural state, the cover plate will close the opening at one end of the connecting pipe away from the branch pipe, and the penetration component will sink into the connecting pipe.

[0007] Optionally, the infiltration component includes a limiting ring, a non-woven fabric and several support rods. The limiting ring is slidably embedded in the connecting tube. The non-woven fabric is rolled into a ring and located between the limiting ring and the cover plate. The two ends of the non-woven fabric respectively abut against the opposite sides of the limiting ring and the cover plate. The support rods are supported between the cover plate and the limiting ring and press the non-woven fabric against the inner wall of the connecting tube, and the support rods are circumferentially arranged on the inner side of the non-woven fabric.

[0008] Optionally, sealing rings are fixedly embedded in the openings at both ends of the non-woven fabric, and sealing grooves are provided on the opposite sides of the cover plate and the limiting ring, and the two sealing rings are fixedly embedded in the two sealing grooves respectively.

[0009] Optionally, the two ends of the support rod are respectively connected to two sealing rings, and every two adjacent support rods are commonly connected to at least one arc-shaped support bar, which presses the non-woven fabric against the inner wall of the connecting tube, and the outer diameter of the support bar is equal to the inner diameter of the non-woven fabric.

[0010] Optionally, the end of the connecting pipe away from the branch pipe has a chamfer and forms a scraping end, and the outer diameter of the scraping end gradually decreases from the end of the connecting pipe connected to the branch pipe to the end of the connecting pipe away from the branch pipe.

[0011] Optionally, at least two groups of the spraying units are provided along the axial direction of the branch pipe. On the same branch pipe, the cover plates of all the spraying units arranged along the axial direction of the branch pipe are connected by a connecting plate, and the connecting plate is provided with slurry holes.

[0012] Optionally, the upper and lower sides of the branch pipe are provided with injection units, the limiting ring is provided with a sliding rod, one end of the sliding rod extends into the branch pipe and is installed with a magnetic block;

[0013] When the cover plate is squeezed by the additive in the connecting pipe, causing the non-woven fabric to extend out of the connecting pipe to a certain length, the two adjacent magnetic blocks located in the same branch pipe will be attracted and fixed to each other, causing the non-woven fabric to extend out of the connecting pipe completely;

[0014] When the cover plate loses the squeezing of the admixture in the connecting pipe, the spring will return to its natural state so that the permeation assembly and the cover plate can be reset.

[0015] Optionally, the feeding unit includes a feeding pump and a feeding pipe, one end of the feeding pipe is connected to the output end of the feeding pump, and the other end of the feeding pipe is rotatably connected to the rotating pipe.

[0016] In a second aspect, in order to achieve the above-mentioned purpose, the embodiments of the present application specifically adopt the following technical solutions: a construction method of a concrete structure construction system based on a plastic alloy formwork, comprising the following steps:

[0017] S1. First, add concrete into the mixing tank through the feed port, and then continuously introduce admixtures into the rotating tube through the feed unit;

[0018] S2. The admixture in the rotating pipe will enter the connecting pipe through the branch pipe. The admixture in the connecting pipe will squeeze the cover plate, causing the cover plate to move out of the connecting pipe. The admixture in the connecting pipe will penetrate into the concrete through the penetration component.

[0019] S3. The rotating tube is driven to rotate by the driving member. The rotating tube drives the branch pipe and the connecting pipe to rotate and mix the concrete and admixture in the mixing tank. The admixture will continue to seep out during the rotation process in the connecting pipe, thereby penetrating into various areas inside the concrete.

[0020] The beneficial effects of the embodiments of the present application are:

[0021] 1. The connection of the two cover plates on the same side of the branch pipe by the connecting plate, the adsorption and fixation of the two adjacent magnetic blocks in the branch pipe, and the adsorption and fixation of the corresponding magnetic columns on the two adjacent branch pipes will make all the non-woven fabrics extend out of the connecting pipe. The flow rate of each injection unit is roughly the same, so the admixture can be evenly penetrated into all areas inside the concrete, improving the mixing effect of the admixture and concrete;

[0022] 2. The motor will drive the rotating tube to rotate through the belt drive, and the rotating tube will drive the branch pipe and the connecting pipe to rotate and mix the concrete and admixture in the mixing tank. The admixture will continue to seep out during the rotation of the branch pipe, so that the admixture can directly penetrate into various areas inside the concrete, thereby improving the mixing quality of the concrete and admixture and the mixing efficiency of the concrete and admixture;

[0023] 3. When the admixture is no longer introduced, the spring will gradually return to its natural state, causing the cover plate and the non-woven fabric to sink into the connecting pipe.

DETAILED DESCRIPTION

[0032] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0033] See also Figure 1-7 , the embodiment of the present application discloses a concrete structure construction system based on plastic alloy formwork. Figure 1 and Figure 2 As shown, a concrete structure construction system based on plastic alloy formwork includes a mixing tank 1, a mixing unit 2 and a feeding unit 3. The mixing tank 1 is provided with a feeding port 11 and a discharging port 12. A hopper 13 is installed at the feeding port 11, and a discharging pipe 14 is installed at the discharging port 12. The discharging pipe 14 is connected to a discharging pump 15.

[0034] The stirring unit 2 includes a rotating tube 21, a driving member and several branch pipes 23. The rotating tube 21 is vertically arranged and coaxially arranged with the stirring tank 1. The rotating tube 21 is rotatably connected to the feeding unit 3 and is rotatably connected to the stirring tank 1 around its own axis; the driving member is a motor 22 installed on the stirring tank 1, and the output shaft of the motor 22 is connected to the rotating tube 21 through a belt drive; the branch pipe 23 is horizontally arranged and connected to the rotating tube 21, and several injection units 4 are provided on the branch pipe 23.

[0035] During the construction process, concrete can enter the mixing tank 1 through the hopper 13 and the feed port 11, and the feeding unit 3 will continuously feed the admixture into the rotating tube 21, and the admixture will pass through the branch pipe 23 and be sprayed into the concrete through the spraying unit 4; at the same time, the motor 22 will drive the rotating tube 21 to rotate through the belt drive, and the rotating tube 21 will drive the branch pipe 23 to rotate and stir the concrete and admixture in the mixing tank 1. The admixture will continue to be sprayed out during the rotation of the branch pipe 23, so that the admixture can directly penetrate into various areas inside the concrete, thereby improving the mixing quality of the concrete and the admixture and the mixing efficiency of the concrete and the admixture.

[0036] When the concrete and the admixture are mixed, the discharge pump 15 extracts the concrete in the mixing tank 1 through the discharge pipe 14 to complete the pouring of the concrete in the plastic alloy formwork.

[0037] The feed unit 3 includes a feed pump 31 and a feed pipe 32. The feed pump 31 is mounted on the mixing tank 1. One end of the feed pipe 32 is connected to the output end of the feed pump 31, and the other end of the feed pipe 32 is rotatably connected to the rotating tube 21. The feed pump 31 can continuously introduce the additive into the rotating tube 21 through the feed pipe 32. The rotation of the feed pipe 32 and the rotating tube 21 make the feed pipe 32 less likely to be twisted by the rotating rotating tube 21.

[0038] At least two groups of spraying units 4 are provided along the axial direction of the branch pipe 23, and spraying units 4 are provided on both the upper and lower sides of the branch pipe 23, so that the spraying units 4 can spray the admixture to various areas inside the concrete, thereby further improving the mixing quality of the concrete and the admixture.

[0039] like Figure 3 and Figure 4 As shown, the injection unit 4 includes a connecting pipe 41, a cover plate 42, a permeation component 43 and a spring 44. The connecting pipe 41 is connected to the side of the branch pipe 23. The cover plate 42 and the permeation component 43 are interconnected and slidably embedded in the connecting pipe 41. The permeation component 43 is connected to the connecting pipe 41 through a spring 44.

[0040] During the continuous introduction of the admixture, if the interior of the rotating tube 21, the interior of the branch tube 23 and the interior of the connecting tube 41 are all filled with the admixture, the admixture will squeeze the cover plate 42, causing the cover plate 42 to move out of the interior of the connecting tube 41. At this time, the penetration component 43 will partially extend out of the connecting tube 41, and the admixture in the connecting tube 41 will seep out of the connecting tube 41 through the penetration component 43, which not only ensures the mixing of the concrete and the admixture, but also makes it difficult for the concrete to enter the connecting tube 41, avoiding the interior of the connecting tube 41 being blocked by concrete. At this time, the spring 44 will be in a deformed state.

[0041] When the admixture is no longer introduced, the spring 44 will gradually return to its natural state, so that the cover plate 42 and the penetration component 43 are both sunk into the connecting pipe 41. At this time, the cover plate 42 will close the opening at one end of the connecting pipe 41 away from the branch pipe 23, preventing the concrete in the mixing tank 1 from entering the connecting pipe 41.

[0042] like Figures 5 to 7 As shown, the infiltration component 43 includes a limiting ring 431, a non-woven fabric 432 and a plurality of support rods 433. The limiting ring 431 is slidably embedded in the connecting tube 41, and the non-woven fabric 432 is rolled into a ring and is located between the limiting ring 431 and the cover plate 42. The two ends of the non-woven fabric 432 respectively abut against the opposite sides of the limiting ring 431 and the cover plate 42 to prevent concrete from entering the connecting tube 41 through the gap between the non-woven fabric 432 and the cover plate 42 and the gap between the non-woven fabric 432 and the limiting ring 431; the support rods 433 are supported between the cover plate 42 and the limiting ring 431 and are circumferentially arranged on the inner side of the non-woven fabric 432, so that the support rods 433 can press the non-woven fabric 432 against the inner wall of the connecting tube 41, thereby minimizing the gap between the non-woven fabric 432 and the inner wall of the connecting tube 41 to prevent concrete from entering the connecting tube 41 as much as possible.

[0043] Sealing rings 434 are fixedly embedded in the openings at both ends of the non-woven fabric 432, and sealing grooves 421 are provided on the opposite sides of the cover plate 42 and the limiting ring 431. The two sealing rings 434 are fixedly embedded in the two sealing grooves 421 respectively. The cooperation between the sealing rings 434 and the sealing grooves 421 realizes the sealed connection between the non-woven fabric 432 and the limiting ring 431, as well as the sealed connection between the non-woven fabric 432 and the cover plate 42.

[0044] The two ends of the support rod 433 are respectively connected to two sealing rings 434, ensuring that the cover plate 42 and the limit ring 431 can move together; every two adjacent support rods 433 are commonly connected to at least one arc-shaped support bar 435, and the support bar 435 presses the non-woven fabric 432 against the inner wall of the connecting pipe 41, and the outer diameter of the support bar 435 is equal to the inner diameter of the non-woven fabric 432, so that the outer wall of the non-woven fabric 432 fits the inner wall of the connecting pipe 41, thereby further preventing concrete from entering the connecting pipe 41.

[0045] The end of the connecting tube 41 away from the branch tube 23 is chamfered and forms a scraping end 411. The outer diameter of the scraping end 411 gradually decreases from the end of the connecting tube 41 connected to the branch tube 23 to the end of the connecting tube 41 away from the branch tube 23. Because the support rods 433 and support bars 435 jointly support the inner side of the non-woven fabric 432, when the non-woven fabric 432 is sunk into the connecting tube 41, the scraping end 411 directly scrapes away concrete adhering to the outer wall of the non-woven fabric 432, thereby preventing concrete from entering the connecting tube 41 along with the non-woven fabric 432.

[0046] On the same branch pipe 23, the cover plates 42 of all the spraying units 4 arranged axially along the branch pipe 23 are connected by a connecting plate 45, so that these cover plates 42 can be detached from the corresponding connecting pipe 41 together to ensure that the admixture can evenly penetrate into various areas inside the concrete.

[0047] like Figure 4 and Figure 5 As shown, the connecting plate 45 is provided with grouting holes 451 , through which concrete can pass, so as to reduce the resistance encountered by the connecting plate 45 during movement.

[0048] One end of the limiting ring 431 away from the cover plate 42 is connected to a slide rod 437 via a connecting frame 436 . The connecting frame 436 is connected to the connecting pipe 41 via a spring 44 . One end of the slide rod 437 extends into the branch pipe 23 and is installed with a magnetic block 438 .

[0049] When the cover plate 42 is squeezed by the admixture in the connecting pipe 41, causing the non-woven fabric 432 to extend a certain length outside the connecting pipe 41, the two upper and lower adjacent magnetic blocks 438 located in the same branch pipe 23 will be adsorbed and fixed to each other, causing the non-woven fabric 432 to extend completely outside the connecting pipe 41, thereby increasing the permeable area of ​​the admixture and improving the penetration effect of the admixture in the concrete; at the same time, the two magnetic blocks 438 adsorbed and fixed to each other will keep the cover plate 42 and the non-woven fabric 432 stable, thereby ensuring the penetration effect of the admixture in the concrete.

[0050] Magnetic columns 452 are fixedly embedded in some of the slurry holes 451. When the non-woven fabrics 432 are all extended out of the connecting pipe 41, the corresponding magnetic columns 452 in the two adjacent branches 23 above and below will be adsorbed and fixed to each other. At this time, all the non-woven fabrics 432 will all extend out of the connecting pipe 41, so that the flow rate of each injection unit 4 is roughly the same, so the admixture can evenly penetrate into various areas inside the concrete, thereby improving the mixing effect of the admixture and concrete.

[0051] The working principle of the present application is as follows: during the construction process, concrete can enter the mixing tank 1 through the hopper 13 and the feed port 11, the feed pump 31 will continuously introduce the admixture into the rotating tube 21 through the feed pipe 32, the admixture in the rotating tube 21 will pass through the branch pipe 23 into the connecting pipe 41, and the admixture in the connecting pipe 41 will squeeze the cover plate 42, so that the cover plate 42 moves out of the inside of the connecting pipe 41; the connecting plate 45 connects the two cover plates 42 on the same side of the branch pipe 23, the two upper and lower adjacent magnetic blocks 438 in the branch pipe 23 are adsorbed and fixed, and the upper and lower adjacent branches 23 are relatively The adsorption and fixation of the corresponding magnetic column 452 will make all the non-woven fabrics 432 extend out of the connecting pipe 41, and the admixture in the connecting pipe 41 will seep into the concrete through the non-woven fabric 432; at the same time, the motor 22 will drive the rotating pipe 21 to rotate through the belt drive, and the rotating pipe 21 will drive the branch pipe 23 and the connecting pipe 41 to rotate and stir the concrete and admixture in the mixing tank 1. The admixture will continue to seep out during the rotation of the branch pipe 23, so that the admixture can directly penetrate into various areas inside the concrete, thereby improving the mixing quality of the concrete and the admixture and the mixing efficiency of the concrete and the admixture.

[0052] When the admixture is no longer introduced, the spring 44 will gradually return to its natural state, the two magnetic blocks 438 that are adsorbed and fixed to each other will separate, and the two magnetic columns 452 that are adsorbed and fixed to each other will also separate, so that the cover plate 42 and the non-woven fabric 432 will both sink into the connecting pipe 41, and the scraping end 411 will scrape off the concrete attached to the outer wall of the non-woven fabric 432, and the cover plate 42 will seal the opening at one end of the connecting pipe 41 away from the branch pipe 23, preventing the concrete in the mixing tank 1 from entering the connecting pipe 41.

[0053] The application embodiment also discloses a construction method of a concrete structure construction system based on a plastic alloy formwork. A construction method of a concrete structure construction system based on a plastic alloy formwork comprises the following steps:

[0054] S1, first add concrete into the mixing tank 1 through the feed port 11, and then continuously introduce admixture into the rotating tube 21 through the feed pump 31;

[0055] S2. The admixture in the rotating tube 21 enters the connecting tube 41 through the branch tube 23. The admixture in the connecting tube 41 squeezes the cover plate 42, causing the cover plate 42 to move out of the connecting tube 41. The admixture in the connecting tube 41 penetrates into the concrete through the non-woven fabric 432.

[0056] S3. The motor 22 drives the rotating tube 21 to rotate. The rotating tube 21 will drive the branch pipe 23 and the connecting pipe 41 to rotate and stir the concrete and admixture in the mixing tank 1. The admixture will continue to seep out during the rotation process in the connecting pipe 41, thereby penetrating into various areas inside the concrete.

A construction method of a concrete structure construction system based on a plastic alloy formwork according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1, first add concrete into the mixing tank (1) through the feed port (11), and then continuously introduce admixture into the rotating tube (21) through the feed unit (3); S2. The admixture in the rotating tube (21) will enter the connecting tube (41) through the branch tube (23). The admixture in the connecting tube (41) will squeeze the cover plate (42), causing the cover plate (42) to move away from the inside of the connecting tube (41). The admixture in the connecting tube (41) will penetrate into the concrete through the penetration component (43); S3. The rotating tube (21) is driven to rotate by the driving member. The rotating tube (21) drives the branch tube (23) and the connecting tube (41) to rotate and stir the concrete and admixture in the mixing tank (1). The admixture will continue to seep out during the rotation process in the connecting tube (41), thereby penetrating into various areas inside the concrete.
