Description

Technical Field

[0001] The invention relates to the technical field of PC assembled buildings, and more specifically, to a building module casting device for PC assembled buildings. Background Art

[0002] As the construction industry's requirements for efficiency and quality continue to increase, PC (precast concrete) prefabricated buildings have been widely used due to their advantages such as fast construction speed and good quality control. This construction method prefabricates building components in the factory and then assembles them on the construction site, which greatly shortens the construction period and reduces the impact of on-site construction on the environment.

[0003] A common method of pouring concrete is one-time pouring. Since a large amount of concrete flows into the building module in a short period of time, it will generate a large impact force, which can easily cause impact damage to the building module and affect its structural strength and integrity. Moreover, one-time pouring makes it difficult to ensure that the concrete is evenly distributed in the building module, and it is easy to have quality problems such as internal voids and honeycombs, which seriously threaten the quality and safety of the building.

[0004] Even if a vibrating rod is used, due to the length limitation of the vibrating rod, when the depth of the building module exceeds the effective length of the vibrating rod, the concrete at the bottom or deep inside the module cannot be fully vibrated, causing bubbles and voids to remain inside the concrete in these areas, greatly reducing the density and strength of the concrete, and thus affecting the structural stability of the building module.

[0016] The beneficial effects of the present invention are:

[0017] 1. The building module casting device for PC prefabricated buildings described in the present invention is provided with a lifting mechanism. During the reciprocating movement of the pouring bucket, the pressure-increasing component pressurizes the inside of the fixed tube, so that the moving column drives the vibrating rod to rise synchronously; during the return stroke, the newly poured concrete is highly matched with the lifted vibrating rod, thereby realizing layered casting; this method effectively reduces the impact damage of concrete to the building module, ensures that each layer of concrete can be fully vibrated, avoids the problem of structural damage to the building module due to one-time casting, and improves the quality and stability of the building module.

[0018] 2. The building module casting device for PC prefabricated buildings described in the present invention is equipped with an up and down toggle mechanism. The up and down toggle mechanism uses the staggered magnetic poles of the third magnetic block and the fourth magnetic block to make the vibrating rod continuously move up and down during the reciprocating motion, thereby expanding the vibration range; at the same time, the first magnetic plate interacts with the second magnetic plate staggered on the auxiliary plate to make the vibrating rod tilt at an angle, further increasing its range of action, and can vibrate the concrete more comprehensively and fully, effectively expel the bubbles inside the concrete, improve the density of the concrete, and ensure the casting quality of the building module.

[0019] 3. The invention discloses a building module casting device for PC prefabricated buildings, which can automatically adjust the size of the discharge port according to the diameter of the vibrating rod. When the forward and reverse screws rotate to drive the clamping plates to clamp vibrating rods of different diameters, the tilting blocks will be squeezed, so that the water source in the storage box pushes the extrusion column to drive the counterweight ring to move upward, releasing the rotating plate, thereby expanding or reducing the discharge port. The larger the diameter of the vibrating rod, the larger the discharge port, and vice versa. This adaptive adjustment function matches the discharge speed with the vibration effect, which not only improves the casting efficiency, but also ensures that the concrete can be fully vibrated and leveled.

DETAILED DESCRIPTION

[0033] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0034] like Figures 1 to 12 As shown, a building module casting device for PC prefabricated buildings according to an embodiment of the present invention includes a support frame 2 installed with a reciprocating drive mechanism; a pouring bucket 602 is located above the support frame 2 and is controlled to reciprocate by the drive mechanism; a mounting frame 606 is fixedly installed inside the pouring bucket 602, and a vibrating rod 704 clamped by a clamping mechanism is also arranged inside the mounting frame 606; a lifting mechanism is fixedly installed inside the mounting frame 606, and the lifting mechanism includes a fixed tube 603 installed with a pressurizing component, and a moving column 619 is arranged inside the fixed tube 603, and the pressurizing component controls the moving column 619 to drive the vibrating rod 704 to be lifted synchronously during the reciprocating movement of the pouring bucket 602; an up and down toggle mechanism is fixedly installed on the moving column 619, and the up and down toggle mechanism includes a third magnetic block 803 and a fourth magnetic block 804, and the fixed third magnetic block 803 controls the clamping mechanism to drive the vibrating rod 704 to move up and down during the movement of the fourth magnetic block 804.

[0035] Specifically, place the building module 1 to be poured inside the support frame 2, and align the discharge port of the pouring hopper 602 with the cavity of the building module 1. Use the clamping mechanism to clamp the vibrating rod 704, so that the vibrating rod 704 is close to the bottom surface of the inner cavity of the building module 1. Subsequently, start the driving mechanism, and the driving mechanism will drive the pouring hopper 602 to reciprocate on the support frame 2. In this way, the inside of the building module 1 can be poured in the first layer, and the vibrating rod 704 will also move together, which can vibrate the poured concrete to make it flat. The poured concrete actually comes into contact with the vibrating rod 704 first, so that vibration and leveling can be carried out during the pouring process. When the pouring hopper 602 moves to one side and is about to move back, the pouring hopper 602 will be pressurized by the pressurizing component in the lifting mechanism, so that the pressurizing component pressurizes the inside of the fixed pipe 603. Under the action of the pressure, the moving column 619 can move upward to drive the vibrating rod 704 to move upward. In this way, when returning, a new layer of concrete will be poured on top of the original concrete, and the lifted vibrating rod 704 will match it, which can vibrate the newly poured concrete and the gap between the two layers of concrete. Thus, it circulates continuously. In this way, not only can the concrete to be poured be effectively poured in layers, and layered pouring can reduce the impact damage of the concrete on the building module 1, but also the vibrating rods 704 can always match each other, so that the vibrating rods 704 can vibrate and level each layer effectively, effectively avoiding the problem that the depth of the building module 1 exceeds the length of the vibrating rod 704 and the vibrating rod 704 cannot be fully leveled. Moreover, during the reciprocating movement of the vibrating rod 704, since there are not only magnets with positive poles but also magnets with negative poles in the third magnet 803, and the magnets with positive and negative poles are arranged alternately, and the poles of the third magnet 803 are fixed, when the fourth magnet 804 moves, it will drive the vibrating rod 704 to move up and down continuously, which can expand the vibration range of the vibrating plate and enable it to act on the concrete within its maximum working range. Finally, by opening the air vent hole on the fixed pipe 603 to discharge the gas, the air pressure is lost, and the moving column 619, the vibrating rod 704, etc. will return to their original states.

[0036] Please refer to Figure 7 , the clamping mechanism includes a limit frame 703; the positive and negative screw rod 710 is rotatably installed on the limit frame 703; the clamping plate 709 is slidably installed inside the limit frame 703 and is threadedly connected to the positive and negative screw rod 710; by rotating the positive and negative screw rod 710, the two clamping plates 709 can be made to approach or move away from each other, and the vibrating rod 704 is placed between the two clamping plates 709, so that it can be clamped by means of the clamping plate 709, which is convenient for subsequent synchronous movement with the pouring hopper 602.

[0037] Please refer to Figure 1 , the lifting mechanism further includes two connecting blocks 601 fixedly connected to the pouring hopper 602;

[0038] Please refer toFigure 1 and Figure 2 The driving mechanism includes a reciprocating screw 5 rotatably connected to the support frame 2, and the reciprocating screw 5 is threadedly connected to the connecting block 601; the motor 4 is fixedly installed on the support frame 2, and its power output shaft is fixedly connected to the reciprocating screw 5; the sliding rod 3 is fixedly installed on the support frame 2 and slidably connected to the connecting block 601; by starting the motor 4, the motor 4 will drive the reciprocating screw 5 to rotate. Due to the limitation of the sliding rod 3, the reciprocating screw 5 will make the connecting block 601 drive the inside of the pouring bucket 602 to reciprocate, and while moving, the building module 1 will be poured. While pouring, the vibrating rod 704 moving together with it will vibrate the concrete to make the concrete level.

[0039] Please refer to Figure 5 and Figure 6 The pressurizing assembly includes a first pressurizing box 604 fixedly connected to a mounting frame 606; a first pressure plate 609, which is slidably mounted inside the first pressurizing box 604 and connected to the first pressurizing box 604 via a second spring 611; a driving frame 608 is fixedly mounted on the first pressure plate 609 and is slidably connected to the filling bucket 602; an air inlet pipe 612 is fixedly mounted below the first pressure plate 609, and a one-way valve is fixedly mounted inside the inlet pipe 612; both ends of the air outlet pipe 610 are respectively connected to the first pressurizing box 604 and the fixed pipe 603, and a one-way valve is fixedly mounted inside the inlet pipe 612; a first spring 607 is located inside the fixed pipe 603, and is used to connect the fixed pipe 603 to the movable column 619.

[0040] Please refer to Figure 2 The up and down toggle mechanism includes a sliding plate 801 that is slidably connected to the support frame 2; when the pouring bucket 602 is driven by the motor 4 to move back and forth on the support frame 2, the driving frame 608 will also move together. When the pouring bucket 602 moves to the other side, the driving frame 608 will squeeze the sliding plate 801, thereby injecting the gas in the first pressurizing box 604 into the fixed tube 603, so that the moving column 619 moves upward, so that the moving column 619 will drive the vibrating rod 704 to move upward through the clamping plate 709, and when the pouring bucket 602 moves back to pour, it will pour a new layer of concrete, and the height will also change, which just matches the height of the vibrating rod 704 after moving up, so that the vibrating rod 704 can always be in a standard working state, and can also vibrate the concrete in layers to make it flat, to ensure that the concrete poured into the building module 1 can fill the building module 1.

[0041] Please refer to Figure 4 and Figure 8The up and down toggle mechanism also includes an extension tube 806 fixedly connected to the moving column 619; the extension column 807 is slidably installed inside the extension tube 806 and is connected to the extension tube 806 through the sixth spring 809; the mounting plate 701 is fixedly connected to the limit frame 703 and is connected to the extension column 807 through the fifth spring 808, and the mounting plate 701 is fixedly connected to the fourth magnetic block 804; the fixed rod 802 is fixedly installed on the two sliding plates 801 and is fixedly connected to the third magnetic block 803; due to the fixed rod 802 and the third magnetic block 803 It is fixed, and the third magnetic block 803 contains not only magnets with positive poles but also magnets with negative poles, and the magnets with positive poles and negative poles are arranged alternately, so that the fourth magnetic block 804 will continuously move the mounting plate 701 up and down due to the interaction between the magnetic poles during the movement, and the up and down movement of the mounting plate 701 will drive the clamped vibration rod 704 to move up and down, so that the vibration rod 704 can also move up and down during the reciprocating motion, so that the vibration rod 704 can further expand its own vibration range and promote the flatness of the concrete.

[0042] Please refer to Figure 8 The up and down toggle mechanism also includes a second pressurizing box 805 fixedly connected to the extension tube 806; the first screw 811 penetrates the second pressurizing box 805 and is rotatably connected to the second pressurizing box 805; the threaded block 810 is slidably installed inside the second pressurizing box 805 and is threadedly connected to the first screw 811; by rotating the first screw 811, the first screw 811 can drive the threaded block 810 to move, and the threaded block 810 moves to squeeze the water source in the second pressurizing box 805, so that the water source squeezes the extension column 807, so that the extension column 807 will drive the clamped vibration rod 704 to move upward, and the placement position of the vibration rod 704 can be adjusted. Fine-tuning is performed to make it more compatible with the layered concrete pouring, and the second pressurizing box 805 is located below the fixed rod 802 and in contact with the fixed rod 802. In this way, during the layered pouring and continuous upward movement of the vibrating rod 704, the fixed rod 802 and the third magnetic block 803 fixed on the fixed rod 802 can be driven to move upward together. In this way, the distance between the third magnetic block 803 and the fourth magnetic block 804 will remain unchanged, and the magnetic force will not be affected by the increase in distance. When it is necessary to restore the original state, the fixed rod 802 and the third magnetic block 803 can be automatically restored to their original positions due to the weight of the sliding plate 801 itself.

[0043] Please refer to Figure 2 and Figure 9 and Figure 10 and Figure 12 , the first mounting tube 605 is fixedly mounted inside the mounting frame 606;

[0044] The second mounting pipe 613 is slidably mounted inside the first mounting pipe 605 and is connected to the mounting plate 701 through the connecting rod 705; the auxiliary plate 618 is located inside the first mounting pipe 605 and is fixedly connected to the first mounting pipe 605 through the limiting block 617. A row of second magnetic plates 620 is fixedly mounted on the auxiliary plate 618; the first magnetic plate 614 is located inside the second mounting pipe 613 and is fixedly connected to the second mounting pipe 613 through the telescopic pipe 616; the third spring 615 is used to connect the first magnetic plate 614 and the second mounting pipe 613; when the third magnetic block 803 and the fourth magnetic block 804 interact to make the vibrating rod 704 communicate with the second mounting pipe 613 and continuously slide up and down inside the first mounting pipe 605, since a row of second magnetic plates 620 fixed on the auxiliary plate 618 are arranged with positive and negative magnetic poles alternating, the moving first magnetic block will continuously interact with the second magnetic plates 620 with positive magnetic poles and the second magnetic plates 620 with negative magnetic poles, so that the first magnetic plate 614 will continuously reciprocally squeeze the vibrating rod 704, and the squeezed vibrating rod 704 will tilt at an angle. After tilting at an angle, it can act on the concrete in a larger range and can better pour the building module 1.

[0045] Please refer to Figure 7 and Figure 11 , the storage box 702 is fixedly mounted on the limiting frame 703; the second pressing plate 707 is slidably mounted inside the storage box 702 and is connected to the storage box 702 through the fourth spring 706; the inclined block 708 is fixedly mounted on the second pressing plate 707; the conveying pipe 902 is fixedly mounted on the storage box 702, and one end close to the storage box 702 is a flexible pipe and the end far from the storage box 702 is a rigid pipe; the counterweight ring 904 is located below the pouring hopper 602 and is slidably connected to the conveying pipe 902 through the extrusion column 905; the discharge pipe 901 is fixedly mounted at the bottom end of the pouring hopper 602, and a rubber hose is also fixedly mounted at its bottom end; the rotating plate 903 is rotatably mounted on the discharge pipe 901, and a torsion spring is also mounted at the rotating connection; when the positive and negative screw rod 710 rotates to drive the two clamping plates 709 to clamp the vibrating rod 704, it will also squeeze the inclined block 708. When the diameter of the vibrating rod 704 is larger, the distance between the two clamping plates 709 will also be larger, so the degree of squeezing the inclined block 708 will also be greater. When the inclined block 708 is squeezed, the water source in the storage box 702 will make the extrusion column 905 drive the counterweight ring 904 to move upward, so that the counterweight ring 904 will continuously release the rotating plate 903, and the rotating plate 903 rotates because of the torsion spring, so that the rubber hose unfolds, so that the size of the discharge port can be enlarged. And the larger the diameter of the vibrating rod 704, the relatively better the vibration effect, and the concrete can be vibrated faster. The corresponding discharge port is also larger. In this way, not only can the pouring be carried out faster, but also the vibrating concrete can be made to match each other to make it flat. When the diameter of the selected vibrating rod 704 is small, the diameter of the discharge port will also become relatively smaller, so that they can always work in mutual matching.

[0046] Working principle: Place the building module 1 to be poured inside the support frame 2, adjust the position of the pouring hopper 602 so that the discharge port is aligned with the cavity of the building module 1; use the clamping mechanism's limit frame 703, left and right screw 710, and clamping plate 709. Rotate the left and right screw 710 to make the two clamping plates 709 approach each other, clamp the vibrating rod 704 between the two clamping plates 709, and ensure that the vibrating rod 704 is close to the bottom surface of the inner cavity of the building module 1.

[0047] Start the motor 4. The motor 4 drives the reciprocating lead screw 5 to rotate. Due to the limiting effect of the sliding rod 3, the connecting block 601 drives the pouring hopper 602 to perform reciprocating linear motion on the support frame 2; during the movement of the pouring hopper 602, the discharge pipe 901 pours concrete into the building module 1. At the same time, the vibrating rod 704 that moves together with the pouring hopper 602 vibrates the freshly poured concrete to make the concrete compact.

[0048] When the pouring hopper 602 moves to one side and is about to return, the driving frame 608 moves with the pouring hopper 602 and squeezes the sliding plate 801; this action causes the gas in the first pressure box 604 to be injected into the fixed pipe 603 through the air outlet pipe 610. The air pressure in the fixed pipe 603 increases, overcoming the elastic force of the first spring 607, and pushing the moving column 619 upward. The moving column 619 drives the vibrating rod 704 to move upward synchronously through the clamping plate 709; at this time, the pouring hopper 602 moves back to continue pouring. The newly poured concrete adds a layer on top of the original, and the lifted vibrating rod 704 can vibrate the newly poured concrete and the gap between the two layers of concrete, realizing layered pouring and layered vibration, reducing the impact damage of the concrete on the building module 1, and ensuring that each layer of concrete can be fully vibrated and compacted.

[0049] During the reciprocating movement of the vibrating rod 704 with the pouring hopper 602, since the third magnetic block 803 is fixed on the fixed rod 802 and its positive and negative magnetic poles are arranged alternately, the fourth magnetic block 804 moves with the vibrating rod 704. Under the interaction of the magnetic poles, it drives the mounting plate 701 to move up and down, and further makes the clamped vibrating rod 704 move up and down, expanding the vibration range of the vibrating rod 704 and promoting the further compaction of the concrete.

[0050] Rotate the first screw 811 to make the threaded block 810 move inside the second pressure box 805, squeezing the water source in the box. The water source pushes the extension column 807 to drive the vibrating rod 704 upward, which can finely adjust the placement position of the vibrating rod 704 to better match the height of the concretes for layered pouring; at the same time, the second pressure box 805 drives the fixed rod 802 and the third magnetic block 803 upward, ensuring that the distance between the third magnetic block 803 and the fourth magnetic block 804 remains unchanged and maintaining the magnetic force effect.

[0051] When the third magnetic block 803 and the fourth magnetic block 804 interact to cause the vibrating rod 704 and the second mounting tube 613 to slide up and down within the first mounting tube 605, the second magnetic plates 620 with positive and negative magnetic poles arranged in an alternating manner on the auxiliary plate 618 interact with the first magnetic plate 614, causing the first magnetic plate 614 to continuously and reciprocally squeeze the vibrating rod 704, resulting in the angle inclination of the vibrating rod 704, thereby acting on the concrete in a larger range and improving the pouring effect.

[0052] When the positive and negative screw 710 rotates to drive the clamping plate 709 to clamp the vibrating rod 704, the clamping plate 709 will squeeze the inclined block 708; the larger the diameter of the vibrating rod 704, the larger the distance between the clamping plates 709, and the greater the squeezing degree on the inclined block 708. The water source in the storage box 702 pushes the extrusion column 905 to drive the counterweight ring 904 to move upward, and the counterweight ring 904 releases the rotating plate 903. The rotating plate 903 rotates under the action of the torsion spring, causing the rubber hose to unfold and the discharge port to become larger; conversely, the smaller the diameter of the vibrating rod 704, the smaller the diameter of the discharge port. In this way, the size of the discharge port matches the vibration effect of the vibrating rod 704, which can not only improve the pouring efficiency but also ensure that the concrete is fully vibrated and leveled.

[0053] The embodiments of the present invention have been described above, but these embodiments are not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
