Description

Technical Field

[0001] This invention relates to a long-line production line and production method for prestressed composite slabs, belonging to the field of composite slab production. Background Technology

[0002] Prestressed concrete composite slabs play a vital role in the construction industry. Their use fully complies with the requirements of industrialized construction and the principles of sustainable development. Prestressed concrete composite slabs reduce steel consumption and the need for reusable materials such as steel pipes and formwork, saving energy, reducing the need for plastering the slab base, and minimizing wet work on site, thus contributing to environmental protection. Furthermore, the use of prestressed concrete composite slabs significantly improves project quality and crack resistance.

[0003] There are two main production processes for precast composite slab components: pre-tensioned fixed production and post-tensioned assembly line production. For composite slabs with the same width, the pre-tensioned fixed production method is more suitable. In the current technology, composite slabs are processed in small workshops, dividing them into several small pieces. The resulting composite slab products have unstable quality, low production efficiency, and high labor costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a long-line production line and method for prestressed composite slabs. To achieve the above objective, the present invention employs the following technical solution:

[0008] Furthermore, the first support leg and the second support leg are provided with vertical sliding grooves for the two ends of the lifting plate to pass through, and a sealing gasket is fixedly provided at one top of the sealing plate to wrap around the through plate and the secondary through plate.

[0009] Furthermore, the electric moving component includes a mounting plate fixed at both ends of the moving platform. A rotary motor is fixedly mounted on the outer side of the mounting plate. The output end of the rotary motor is connected to a drive roller corresponding to the long slide groove. A bearing is embedded in the mounting plate. The bearing is connected to a secondary drive roller corresponding to the secondary long slide groove. A round rod is fixedly mounted on the drive roller. An L-shaped bracket is fixedly mounted on the mounting plate. A bearing connecting the round rod is embedded in the L-shaped bracket. A reinforcing rib is also fixedly mounted between the rotary motor and the mounting plate.

[0010] Furthermore, the stirring roller is fixedly provided with a plurality of L-shaped hanging rods, and the tilting assembly includes an electric telescopic rod hinged to the bottom end of the moving platform. The bottom end of the electric telescopic rod is fixedly provided with a flat plate, and both ends of the bottom of the flat plate are fixedly provided with connecting parts. The connecting parts are hinged to the outer surface of the stirring drum. The bottom end of the moving platform is also fixedly provided with two connecting columns, which are hinged to the outer surface of the stirring drum.

[0011] Furthermore, a fixed platform is fixedly provided at one end of the moving platform, and a storage box is fixedly provided at the bottom end of the fixed platform. The storage box stores a release agent. A spray pump is connected to the storage box through a flexible pipe. The spray pump is connected to a spray chamber through a pipe. Several bottom nozzles are provided on the spray chamber, and several horizontal nozzles are respectively provided on both ends of the outer wall of the spray chamber. A sleeve is fixedly provided at the bottom end of the moving platform, and a sleeve rod is fitted inside the sleeve. A cleaning plate is fixedly provided at the bottom end of the sleeve rod. A bottom brush plate with bristles is fixedly provided at the bottom end of the cleaning plate by bolts. Horizontal brush plates with bristles are respectively provided on both ends of the outer wall of the cleaning plate by bolts.

[0012] Furthermore, a forward and reverse motor is fixedly installed at the bottom of the fixed platform, and a bidirectional lead screw is connected to the output bottom of the forward and reverse motor.

A second through plate is fixedly installed on the outer wall of the storage box, and the connecting rod on the spray pump passes through the second through plate. A third bearing that is sleeved on the bottom of the bidirectional lead screw is fixedly installed on the second through plate.

[0013] Furthermore, the machine is equipped with multiple heating water pipes embedded within it, which are interconnected and connected to an external hot water source.

[0014] The production method of a prestressed composite slab long line production line includes the following steps:

[0015] Step 1: First, remove debris from the mold cavity using the bottom brush plate and the horizontal brush plate, and then spray the mold release agent into the mold using the horizontal nozzle and the bottom nozzle.

[0016] Step 2: Then pour concrete into the mold cavity and compact it. When the composite slab initially sets, heat the inner surface of the mold cavity to increase the concrete curing temperature and shorten the curing cycle.

[0017] Step 3: After the final composite plate has completely solidified, demold the composite plate through the outlet.

[0018] The beneficial effects of this invention are:

[0019] Hydraulic rods are used to drive the lifting plate, fixing rod, sealing plate, through plate, and auxiliary through plate for auxiliary lifting. As a result, the through plate and auxiliary through plate just pass into the mold cavity, thus forming a casting space between them. Then, the steel reinforcement assembly is placed into the mold cavity, that is, placed between the through plate and auxiliary through plate, ensuring that the cast material contains the steel reinforcement assembly after casting. Therefore, the cast composite plate has high production strength.

[0020] Furthermore, when placing the rebar assembly, the adjusting component drives the two adjacent opposing plates to move closer and further apart. This causes the opposing plates and the through rod to move within the corresponding moving slots, enabling the two adjacent limiting plates to move closer and further apart, thus clamping each rebar assembly and preventing the rebar assembly from tipping over during the pouring process and affecting the pouring work.

[0021] Concrete is poured into the mixing drum and thoroughly mixed using mixing rollers and blades. Finally, it is discharged from the discharge port into the mold cavity. External vibration machinery is used to vibrate the concrete. When the composite slab has initially set, the through slab and the secondary through slab are retrieved. A film is then laid on the machine platform and then cured with hot water to shorten the curing time. Attached Figure Description

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Please see Figures 1-8This invention provides a technical solution: a prestressed composite slab long-line production line, including a machine base 1. A mold cavity 2 is formed inside the top of the machine base 1. Long slide grooves 3 are formed on both sides of the top of the machine base 1, and secondary long slide grooves 4 are formed on both sides of the outer wall of the machine base 1. A discharge port 5 is located at the tail end of the top of the machine base 1. An electric moving assembly matching the long slide grooves 3 and secondary long slide grooves 4 is provided on the machine base 1. A moving platform 6 is provided on the electric moving assembly. An inclined assembly is provided at the bottom of the moving platform 6. The inclined assembly is connected to a stirring drum 7. A stirring motor 8 is fixedly installed on the outer wall of the stirring drum 7. The output end of the stirring motor 8 is connected to a stirring roller 9 located inside the stirring drum 7. Stirring blades 10 are arranged on the stirring roller 9. The stirring drum 7 has a feed inlet and a discharge outlet 11 with control valves. A first support leg 12 and a second support leg 13 are fixedly installed at the bottom of the machine base 1. A transverse plate is fixed between the first support leg 12 and the second support leg 13. Multiple hydraulic rods 14 are fixedly mounted on the horizontal plate. A lifting plate 15 is fixedly mounted on the output top of each hydraulic rod 14. An adjusting assembly is mounted on the lifting plate 15, and several pairs of opposing plates 16 are mounted on the adjusting assembly. Several through-plates 17 and two auxiliary through-plates 18 are provided through the bottom of the machine base 1. Sealing plates 19 are fixedly mounted at the bottom ends of both through-plates 17 and the two auxiliary through-plates 18. The opposing plates 16 pass through the corresponding through-plates 17 and auxiliary through-plates 18. A through rod 20 is fixedly provided on the plate 16, passing through the through plate 17 and the secondary through plate 18. A limiting plate 21 is fixedly provided at the other end of the through rod 20. The through plate 17 and the secondary through plate 18 are both provided with moving grooves 22 for the through rod 20 and the plate 16 to move. A casting space is formed between adjacent limiting plates 21. A steel reinforcement assembly 23 is placed in the casting space. The sealing plate 19 and the lifting plate 15 are connected by a fixing rod 32.

[0034] See Figures 2-3 The reinforcing bar assembly 23 includes a transverse steel plate 24. Multiple reinforcing bar support feet 25 are fixedly provided at the bottom of the transverse steel plate 24. Multiple transversely arranged positioning reinforcing bars 26 are fixedly provided at both ends of the transverse steel plate 24. Adjacent limiting plates 21 have positioning holes 27 corresponding to the positioning reinforcing bars 26. The reinforcing bar assembly 23 is placed into the mold cavity 2, that is, between the through plate 17 and the secondary through plate 18. An adjusting component drives the adjacent two limiting plates 21 to move, clamping the reinforcing bar assembly 23. The positioning reinforcing bars 26 on the reinforcing bar assembly 23 are inserted into the positioning holes 27, thus preventing the reinforcing bar assembly 23 from tipping over during the pouring process and affecting the pouring work. The final poured composite slab... Figure 8 It can be seen directly in the middle.

[0035] See Figure 2 The adjustment assembly includes a drive motor 28 fixed on the lifting plate 15. The output end of the drive motor 28 is connected to a rotating rod 29. The rotating rod 29 is arranged with multiple sets of externally threaded sections 30 with opposite threads. Threaded plates 31 are fixedly provided at the bottom ends of the opposing plates 16. The threaded plates 31 are threaded onto the externally threaded sections 30. Vertical grooves 33 are provided on the first support leg 12 and the second support leg 13 for the two ends of the lifting plate 15 to pass through. A sealing washer 34 is fixedly provided at the top of the sealing plate 19 to cover the first through plate 17 and the second through plate 18. The first support leg 12 and the second support leg 13... The support leg 13 supports the entire equipment, so the first support leg 12 and the second support leg 13 must be made of steel. During the lifting process of the hydraulic rod 14 driving the lifting plate 15, it needs to be stable. Therefore, the vertical slide groove 33 is designed to limit the two ends of the lifting plate 15 to ensure stable lifting. The sealing gasket 34 finally abuts against the bottom surface of the machine platform to ensure the leakage prevention performance of the penetration. The drive motor 28 drives the external thread section 30 on the rotating rod 29 to rotate, so it can directly drive the adjacent threaded plates 31 to move closer and further away from each other. The ultimate goal is to achieve the movement of the two adjacent limiting plates 21 to move closer and further away from each other, thus completing the clamping of each steel bar component 23.

[0036] See Figure 1 and Figure 5 The electric moving assembly includes mounting plates 35 fixed at both ends of the moving platform 6. A rotary motor 36 is fixedly mounted on the outer side of the mounting plate 35. The output end of the rotary motor 36 is connected to a drive roller 37 corresponding to the long slide groove 3. A bearing 38 is embedded in the mounting plate 35. The bearing 38 is connected to a secondary drive roller 39 corresponding to the secondary long slide groove 4. A round rod is fixedly mounted on the drive roller 37. An L-shaped bracket is fixedly mounted on the mounting plate 35. A bearing 40 connecting the round rod is embedded in the L-shaped bracket. The rotary motor 36 and the mounting plate 35 are also connected... The fixed reinforcing ribs 41 and the bearing design are all to ensure the rotational stability of the rollers. The main electric components of the electric moving assembly are designed on the setting plate 35. Multiple electric components can be designed on each setting plate 35 to ensure more sufficient moving force. The rotary motor 36 directly drives the drive roller 37 to rotate in the long slide 3, which ultimately drives the moving platform 6 and all components on the moving platform 6 to move, so as to realize subsequent pouring, cleaning and other work. The auxiliary drive roller 39 provides assistance in driving in the secondary long slide 4, further ensuring the moving stability of the setting plate 35, and also serving to support the setting plate 35 and the moving platform 6.

[0037] See Figure 6The mixing roller 9 is fixedly provided with multiple L-shaped hanging rods 42. The tilting component includes an electric telescopic rod 43 hinged to the bottom end of the moving platform 6. A flat plate is fixed to the bottom end of the electric telescopic rod 43. Connecting parts 44 are fixed to both ends of the bottom of the flat plate. The connecting parts 44 are hinged to the outer surface of the mixing drum 7. Two connecting columns 45 are also fixedly provided to the bottom end of the moving platform 6. The connecting columns 45 are hinged to the outer surface of the mixing drum 7. The L-shaped hanging rods 42 can scrape and clean the concrete inside the mixing drum 7. Since the two ends of the electric telescopic rod 43 are hinged, the extension of the electric telescopic rod 43 itself drives the mixing drum 7 to tilt, thereby making its discharge smoother. Because the material inside the mixing drum 7 is small, the discharge speed is greatly reduced. The design of a large number of connecting parts 44 and connecting columns 45 results in high support stability of the mixing drum 7.

[0038] See Figure 1 and Figure 7 The movable platform 6 has a fixed platform 46 at one end, and a storage box 47 at the bottom of the fixed platform 46. The storage box 47 stores a release agent. The storage box 47 is connected to a spray pump 48 via a flexible pipe. The spray pump 48 is connected to a spray chamber 49 via a pipe. The spray chamber 49 has several bottom nozzles 50, and several horizontal nozzles 51 are respectively provided on both ends of the outer wall of the spray chamber 49. The movable platform 6 has a sleeve 52 fixed at the bottom, and a sleeve rod 53 is fitted inside the sleeve 52. A cleaning plate 54 is fixed at the bottom of the sleeve rod 53. A bottom brush plate 55 with bristles is fixed to the bottom of the cleaning plate 54 by bolts. Horizontal brush plates 56 with bristles are respectively provided on both ends of the outer wall of the cleaning plate 54 by bolts. A forward and reverse motor 57 is fixed at the bottom of the fixed platform 46. The output bottom of the forward and reverse motor 57 is connected to a double... Connecting rods 59 are fixedly installed on the housing of the lead screw 58 and the spray pump 48 and the sleeve rod 53, respectively. The connecting rods 59 are threaded onto the bidirectional lead screw 58. A through plate 60 is fixedly installed on the outer wall of the storage box 47. The connecting rods 59 on the spray pump 48 pass through the through plate 60. A bearing 3 is fixedly installed on the through plate 60 and sleeved at the bottom of the bidirectional lead screw 58. After removing debris from the mold cavity 2 through the bottom brush plate 55 and the horizontal brush plate 56, the release agent is evenly sprayed into the mold cavity 2 through the bottom nozzle 50 and the horizontal nozzle 51 to facilitate the demolding effect of the subsequent stacked plate. The forward and reverse motor 57 drives the bidirectional lead screw 58 to rotate. Therefore, during the process of driving the spray pump 48 and the spray cavity 49 to descend, the cleaning plate 54 is in an upward movement. Conversely, the cleaning plate 54 is in a downward movement. Thus, the effect of removing debris from the mold cavity 2 and spraying the release agent is completed.

[0039] See Figure 1The machine base 1 is equipped with multiple heating water pipes 61 embedded in it. The heating water pipes 61 are interconnected and connected to an external hot water source. Hot water flows inside the pipes, thereby heating the inner surface of the mold cavity 2, thus increasing the concrete curing temperature and shortening the curing cycle.

[0040] The production method of a prestressed composite slab long line production line includes the following steps:

[0041] Step 1: First, remove debris from the mold cavity using the bottom brush plate and the horizontal brush plate, and then spray the mold release agent into the mold using the horizontal nozzle and the bottom nozzle.

[0042] Step 2: Then pour concrete into the mold cavity and compact it. When the composite slab initially sets, heat the inner surface of the mold cavity to increase the concrete curing temperature and shorten the curing cycle.

[0043] Step 3: After the final composite plate has completely solidified, demold the composite plate through the outlet.

[0044] In specific operation, the hydraulic rod 14 is used to drive the lifting plate 15, the fixed rod 32, the sealing plate 19, the through plate 17 and the auxiliary through plate 18 to perform auxiliary lifting. Therefore, the through plate 17 and the auxiliary through plate 18 just pass into the mold cavity 2, thus forming a casting space between the through plate 17 and the auxiliary through plate 18. Then, the steel reinforcement assembly 23 is placed in the mold cavity 2, that is, placed between the through plate 17 and the auxiliary through plate 18, to ensure that the cast material contains the steel reinforcement assembly 23 after casting. Therefore, the cast composite plate has high production strength.

[0045] Furthermore, when placing the rebar assembly 23, the adjusting component drives the two adjacent relative plates 16 to move closer to each other and further away from each other. This causes the relative plates 16 and the through rod 20 to move within the corresponding moving groove 22, enabling the two adjacent limiting plates 21 to move closer to each other and further away from each other, thus clamping each rebar assembly 23 and preventing the rebar assembly 23 from tipping over during the pouring process and affecting the pouring work.

[0046] Concrete is poured into the mixing drum 7 and thoroughly mixed using the mixing roller 9 and mixing blades 10. Finally, it is discharged from the discharge port 11 into the mold cavity 2. The concrete is then vibrated using external vibration machinery. When the composite slab has initially set, the through plate 17 and the secondary through plate 18 are retrieved. The slab is then laid on the machine platform 1 and cured with hot water to shorten the curing time.

[0047] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
