Description

A modular precast concrete casting formwork Technical Field

[0001] This invention belongs to the field of modular template technology, and in particular relates to a modular precast concrete casting template. Background Technology

[0002] As the construction industry pursues industrialized production methods, traditional on-site pouring operations suffer from inconsistent quality and efficiency due to factors such as weather and worker skill levels. The emergence of PPVC modular casting formwork technology aims to achieve factory prefabrication of building components, mass-producing high-quality building modules like industrial products. This method allows for better control of quality and schedule, making construction closer to the standardized processes of manufacturing. Traditional formwork has limitations in splicing precision and stability, which may lead to quality problems such as gaps and unevenness in the structure after concrete pouring. PPVC modular casting formwork adopts high-precision design and manufacturing processes, which can ensure tight connections between modules, providing a guarantee for high-quality concrete pouring.

[0003] In the existing technology (publication number CN114789501B, patent application titled "An Aluminum Formwork for Precast Concrete Pouring"), an aluminum formwork body is included. Multiple receiving grooves are formed on the side walls of the aluminum formwork body. A grinding plate is rotatably mounted within each receiving groove. The surface of the grinding plate is flush with the front of the aluminum formwork body and has a grinding texture. A cavity is formed inside the aluminum formwork body, and a control rod is rotatably supported within the cavity. One end of the control rod protrudes from the front of the aluminum formwork body. A transmission assembly is provided between the control rod and the multiple grinding plates. This technology has the advantage of improving the ease of disassembly of the aluminum formwork. However, in implementing this technical solution, at least the following problems were found in the existing technology.

[0004] Currently used precast concrete casting templates have smooth surfaces, which generally do not cause burrs on the surface of the precast concrete casting. Therefore, there is no need to use multiple grinding plates to grind the precast concrete casting, leaving areas that cannot be ground. However, mechanized rapid splicing methods cannot be used to quickly cast the precast concrete casting. Frequent manual intervention with tools is required, which is time-consuming, labor-intensive, costly, and results in low casting efficiency. Summary of the Invention

[0016] The modular precast concrete casting template of the present invention has the following advantages: 1. The modular precast concrete casting template is first provided with a unified drive source by a dual-head motor, which saves power costs. At the same time, the first electric push rod in the short rotating shaft adjusts the meshing position between the main bevel gear and the two sets of auxiliary bevel gears.

[0017] 2. This modular precast concrete casting template, firstly, uses two second electric push rods to adjust the meshing position between the two sets of auxiliary and main spherical gears. Then, the main spherical gear on the double-headed motor drives two threaded rods to rotate through the two sets of auxiliary spherical gears. The two threaded rods then drive the push rods to move horizontally through the push plates on the two threaded cylinders. The push plates, through the two push rods, drive the inner mold to quickly assemble and cast or disassemble between the base plate and the back wall plate and the long and short wall panels. This greatly saves on manual labor intensity and cost, and improves the molding and demolding efficiency of modular precast concrete castings.

[0018] 3. This modular precast concrete casting template first adjusts the meshing stroke between the driven bevel gear and the driving bevel gear using a third electric push rod. Then, the driving bevel gear on the other side of the dual-head motor drives the planetary bevel gear on the long rotating shaft to rotate through the driven bevel gear. The planetary bevel gear drives the two sets of bevel gear frames to rotate after they are in place. The two bevel gear frames drive the long rotating rods on the two sets of differential bevel gears to rotate accordingly. The two long rotating rods drive the two sets of cam frames, push rod frames, return springs and vibration seats to perform horizontal reciprocating striking actions, which vibrates and evens the material in the casting area between the long and short wall panels and the inner mold, thereby improving the molding quality of the modular precast concrete casting.

Side frames 5 are fixedly connected to the outer sides of the long wall panels 3 and short wall panels 4, and side cylinders 6 are fixedly connected to the sides of the base frame 2 near the long wall panels 3 and short wall panels 4. A rear wall panel 7 is fixedly connected to the back of the base plate 1, and a top cylinder 8 is fixedly connected to the back of the rear wall panel 7 through a bracket. An inner mold 9 is provided on the front of the base plate 1 for use with the long wall panels 3 and short wall panels 4. Furthermore, the inner sides of the long wall panel 3 and the short wall panel 4 are arrayed with grooves 25, which are suitable for the forming requirements of the side of the precast concrete casting and also enhance the strength of the side of the precast concrete casting. The top array of the long wall panel 3 and the short wall panel 4 facing each other is connected with wall clamps 26, so that the long wall panel 3 and the short wall panel 4 are connected into a whole after being spliced, which improves its overall stability. The side of the long wall panel 3 and the short wall panel 4 near the inner mold 9 is provided with a sealing plate to prevent material leakage. Furthermore, the surfaces of the long wall panel 3, the short wall panel 4, the inner mold 9, the base plate 1 and the rear wall panel 7 are all smoothed and coated with an anti-stick coating to avoid causing too many burrs to the precast concrete casting after forming, making the surface of the precast concrete casting smoother and also facilitating the demolding of the precast concrete casting. The top cylinder 8 is equipped with a hopper 27, which facilitates the material feeding operation of the long wall panel 3, short wall panel 4, inner mold 9, base plate 1 and the reserved casting area of ​​the rear wall panel 7.Furthermore, a material level sensor 28 is embedded at the bottom of the front of the hopper 27 to monitor the material level prepared in the hopper 27 in real time, so as to replenish the hopper 27 in a timely manner. The long wall panel 3, short wall panel 4, inner mold 9, base plate 1 and rear wall panel 7 are all made of high-strength metal or engineering plastic, which improves the overall material strength of the long wall panel 3, short wall panel 4, inner mold 9, base plate 1 and rear wall panel 7. Pressure sensors or liquid level sensors are embedded on the inner side of the long wall panel 3, short wall panel 4 and inner mold 9 to monitor the material pressure and liquid level in real time during the molding process, so as to prevent the material pressure from being too high and causing damage, and also to prevent the material liquid from leaking. At the same time, the joint gaps between the base plate 1, rear wall panel 7, long wall panel 3, short wall panel 4 and inner mold 9 are sealed with sealing strips made of elastic materials such as rubber or silicone to seal the joint positions, further preventing material leakage, making them a whole, which is beneficial to the molding quality of the precast concrete casting. Furthermore, both sides of the base frame 2 are equipped with first adjustment components 10 for adjusting the displacement of the long retaining wall panel 3 and the short retaining wall panel 4, and the front of the base frame 2 is equipped with a second adjustment component 11 for adjusting the displacement of the inner mold 9.

The side frame 5 is equipped with a drive component 12 and a vibration component 13, which are used for vibrating the material between the long retaining wall panel 3 and the short retaining wall panel 4 and the inner mold 9, and vibrating the material in the pouring area between the long retaining wall panel 3 and the short retaining wall panel 4 and the inner mold 9 to improve the molding quality of the modular precast concrete casting. .

A first electric push rod 103 is embedded at the other end of the inner cavity of the short rotating shaft 102. The piston rod of the first electric push rod 103 is fixedly connected to a main bevel gear 104, and secondary bevel gears 105 are provided on both sides of the main bevel gear 104. Firstly, the dual-head motor 101 provides a unified drive source, saving power costs. Simultaneously, the first electric push rod 103 within the short rotating shaft 102 adjusts the meshing position between the main bevel gear 104 and the two sets of secondary bevel gears 105. A threaded short rod 106 is fixedly connected to the outer side of the wheel 105 and rotates with the side cylinder 6. A threaded sleeve 107 is threadedly connected to the threaded short rod 106. Push seats 108 that slide with the side cylinder 6 are fixedly connected to both sides of the threaded sleeve 107. The inner side of the push seat 108 is fixedly connected to the outer side of the long wall plate 3 and the short wall plate 4 respectively. The threaded sleeve 107 on the two threaded short rods 106 drives the long wall plate 3 and the short wall plate 4 on the two sets of push seats 108 to adjust their displacement in the same way, so as to meet the requirements of rapid assembly, casting or disassembly and demolding between the long wall plate 3 and the short wall plate 4 and the base plate 1 and the rear wall plate 7. Short guide rods 15 are fixedly connected to both sides of the base frame 2 near the side cylinder 6, and sliding sleeves 16 that are fitted into the push seat 108 are slidably connected to the short guide rods 15.

This provides rolling support for the long wall panel 3 and the short wall panel 4 as they are spliced ​​inward and reset outward, reducing the pushing and pulling burden of the push seat 108 on the long wall panel 3 and the short wall panel 4, and further improving the displacement stability of the long wall panel 3 and the short wall panel 4.

[0024] The second adjustment assembly 11 includes a main sprocket 111 fixed on the output shaft of the dual-head motor 101 near the short rotating shaft 102, and auxiliary sprockets 112 are provided on both sides of the main sprocket 111. Secondary electric push rods 113 are fixedly connected to the front of the auxiliary sprockets 112. The two secondary electric push rods 113 first adjust the meshing position between the two sets of auxiliary sprockets 112 and the main sprocket 111. A threaded long rod 114, which rotatably engages with the base frame 2, is sleeved on the outer side of the secondary electric push rod 113. Then, the main sprocket 111 on the dual-head motor 101 drives the two threaded long rods 114 to rotate through the two sets of auxiliary sprockets 112. The threaded long rods 114 are threadedly connected to a component that slidably engages with the base frame 2. A threaded long cylinder 115 is provided with a push plate 116 on the front side of the threaded long cylinder 115. Push rods 117 that are fixedly connected to the two sides of the push plate 116 and are fixedly engaged with the inner mold 9 are fixedly connected to both sides of the push plate 116.

The push plate 116 drives the inner mold 9 to quickly splice and pour or disassemble and demold between the base plate 1 and the rear wall plate 7 and the long wall plate 3 and the short wall plate 4, which greatly saves the intensity and cost of manual intervention and improves the molding and demolding efficiency of modular precast concrete pouring. The top two sides of the base plate 1 are fixedly connected to the slide rail frame 21, and the inner cavity of the inner mold 9 is fixedly connected to the inner skeleton 22. The bottom of the inner skeleton 22 is rotatably connected to the slide rail wheel 23 that rolls with the slide rail frame 21. This provides rolling support for the inner mold 9 as it splices inward and resets outward, improving the smoothness of the displacement of the inner mold 9 and reducing the pushing and pulling burden of the push rod 117 on the inner mold 9. The top of the inner mold 9 is provided with a top hole on one side to provide opening mold support for the subsequent precast concrete pouring.

[0025] The drive assembly 12 includes a drive bevel gear 121 fixed on another output shaft of the dual-head motor 101, and a driven bevel gear 122 is disposed above the drive bevel gear 121. A third electric push rod 123 is fixedly connected to the top of the driven bevel gear 122. The third electric push rod 123 first adjusts the meshing stroke between the driven bevel gear 122 and the drive bevel gear 121. A long rotating shaft 124 that rotatably engages with the top cylinder 8 is sleeved on the outer side of the third electric push rod 123. Then, the drive bevel gear 121 on the other side of the dual-head motor 101 drives the planetary bevel gear 125 on the long rotating shaft 124 to rotate through the driven bevel gear 122. The planetary bevel gear 125 is fixedly connected to the bottom of the long rotating shaft 124, and bevel gear frames 126 that rotatably engage with the side frame 5 are disposed on both sides of the planetary bevel gear 125. The planetary bevel gear 125 drives the two sets of bevel gear frames 126 to rotate after they are in position. The vibration assembly 13 includes a differential bevel gear 131 meshing with the other end of the bevel gear frame 126. A long rotating rod 132, which rotatably engages with the side frame 5, is fixedly connected to the inner cavity of the differential bevel gear 131. The two bevel gear frames 126 drive the long rotating rods 132 on the two sets of differential bevel gears 131 to rotate accordingly. Cam frames 133 are fixedly connected to both sides of the long rotating rod 132. A push rod frame 134 is rotatably connected to the inner side of the cam frame 133.

A vibration seat 1, which engages with the vibrating material of the long guard plate 3 and the short guard plate 4, is fixedly connected to the inner side of the push rod frame 134. 36. Two long rotating rods 132 drive two sets of cam frames 133, push rod frames 134, return springs 135 and vibration seats 136 to perform horizontal reciprocating striking motions, which vibrate and even out the material in the pouring area between the long wall panel 3 and the short wall panel 4 and the inner mold 9, thereby improving the molding quality of the modular precast concrete pouring. A buffer pad 24 is fixedly connected to the side of the vibration seat 136 near the long wall panel 3 and the short wall panel 4, which plays a role in buffering and silencing the striking vibration area of ​​the vibration seat 136 and the long wall panel 3 and the short wall panel 4, so as to prevent the vibration seat 136 from causing dents and damage to the striking vibration area of ​​the long wall panel 3 and the short wall panel 4.

[0026] As shown in Figures 17-19, during the modular pouring of precast concrete structures, materials are usually first added to the hopper 27 by a concrete truck, and then the hopper 27 is moved back and forth by a crane via a wire rope to unload the material. This method is not only inefficient but also costly, making it unprofitable. The top cylinder 8 is equipped with a material distribution assembly 14 that works in conjunction with the hopper 27. The material distribution assembly 14 includes a worm gear 141 fixed to the top of the long rotating shaft 124, with meshing couplings on both sides of the worm gear 141. The top cylinder 8 is rotatably fitted with a worm gear 142. The long rotating shaft 124 drives two sets of worm gears 142 to rotate through the worm 141. The front of the worm gear 142 is fixedly connected to a reciprocating screw 143. Both sides of the two sets of reciprocating screws 143 are threadedly connected to screw sleeves 144. The top of the screw sleeves 144 is fixedly connected to a connecting seat 145 that slides with the top cylinder 8. The connecting seat 145 is fixedly connected to the hopper 27. The two sets of worm gears 142 drive the two reciprocating screws 143 to rotate. Simultaneously, two reciprocating lead screws 143 drive two sets of lead screw sleeves 144 to move horizontally back and forth. The two sets of lead screw sleeves 144 drive the hopper 27 to move horizontally back and forth through two sets of connecting seats 145. Both sides of the bottom of the hopper 27 are connected to four-way valves 146, and both ends of the four-way valves 146 are connected to distribution pipes 147. The bottom of the four-way valves 146 and the distribution pipes 147 are connected to distribution heads 148 for material distribution. The hopper 27 performs uniform material distribution through the two sets of four-way valves 146 and the distribution heads 148 on the distribution pipes 147, improving the uniformity of material distribution and avoiding uneven material distribution that could lead to quality problems in subsequent precast concrete pouring.

[0027] The working principle of a modular precast concrete casting template: During the modular forming of the precast concrete casting, the first electric push rod 103 is activated, driving the main bevel gear 104 forward to engage with the meshing part of the two sets of secondary bevel gears 105. Then, the dual-head motor 101 is activated, and through the short rotating shaft 102, it drives the engaged main bevel gear 104 and the two sets of secondary bevel gears 105 to rotate in opposite directions. The two sets of secondary bevel gears 105 drive the two threaded short rods 106 to rotate accordingly. The two threaded short rods 106 drive the two sets of threaded sleeves 107 to move inward synchronously. The two sets of threaded sleeves 107 drive the two sets of push seats 108 to move inward accordingly. As the plates move inward, the two sets of short guide rods 15, sliding sleeves 16, and buffer springs 17 provide sliding support for the two sets of push seats 108. With the rolling support of the two sets of guide rail frames 18, support frames 19, and guide wheels 20, the two sets of push seats 108 synchronously drive the long guard plate 3 and short guard plate 4 towards the base plate 1 and rear wall plate 7 until the long guard plate 3 and short guard plate 4 are properly joined with the base plate 1 and rear wall plate 7. Then, the dual-head motor 101 is first stopped, and the first electric push rod 103 is closed, driving the main bevel gear 104 to move backward, disengaging from the meshing of the two sets of secondary bevel gears 105 to its initial position. Immediately afterwards, the two second electric push rods 113 are first opened, driving the two sets of secondary spur gears 112 to move backward and engage with the main spur gear 111. After the meshing part is engaged, the dual-head motor 101 is restarted and the main sprocket 111, which is in position, drives the two sets of auxiliary sprockets 112 to rotate. The two sets of auxiliary sprockets 112 drive the two threaded rods 114 to rotate accordingly. The two threaded rods 114 drive the two threaded cylinders 115 to move backward synchronously. The long smooth rod 118, which moves along with it, provides sliding support between the push plate 116 and the base frame 2. Under the rolling support of the slide rail frame 21, the inner skeleton 22, and the slide rail wheel 23 on the inner mold 9, the two threaded cylinders 115 drive the two push rods 115 through the push plate 116. The inner mold 9 on 17 moves towards the base plate 1 until the inner mold 9 reaches the correct position of the long protective wall plate 3 and the short protective wall plate 4 with the base plate 1 and the rear wall plate 7. Then, the dual-head motor 101 is controlled to pause, and the two second electric push rods 113 are controlled to close and drive the two sets of auxiliary spur gears 112 to move forward and disengage from the meshing part of the main spur gear 111 to the initial position. Then, several wall clamps 26 are tightened and fixed between the long protective wall plate 3 and the short protective wall plate 4. Thus, the overall splicing work of the base plate 1, the rear wall plate 7, the long protective wall plate 3, the short protective wall plate 4 and the inner mold 9 before pouring is completed.Then, the third electric push rod 123 is first controlled to open and drive the driven bevel gear 122 to move down and engage with the drive bevel gear 121. Then, the dual-head motor 101 is controlled to reopen and drive the driven bevel gear 122 to rotate through the engaged drive bevel gear 121. The driven bevel gear 122 drives the planetary bevel gear 125 on the long rotating shaft 124 to rotate accordingly. At the same time, the long wall panel 3 and the short wall panel 4 are spliced ​​into place towards the base plate 1 and the rear wall panel 7, and at the same time, the two sets of side frames 5 on them drive the two bevel gear frames 126 to move inward and engage with the engagement part of the planetary bevel gear 125. Then, the planetary bevel gear 125 drives the two bevel gear frames 126 to rotate. The other gear of the two bevel gear frames 126 drives the two sets of differential bevel gears 131 to rotate accordingly. The two sets of differential bevel gears 131 drive the two sets of differential bevel gears 131 through the two long rotating rods 132. The cam frame 133 rotates. When the outermost ends of the two sets of cam frames 133 rotate to the head positions of the two sets of push rod frames 134, the two sets of push rod frames 134 drive the two sets of vibration seats 136 and buffer pads 24 to strike the long wall plate 3 and the short wall plate 4, and compress the two sets of return springs 135. At this time, the two sets of vibration seats 136 and buffer pads 24 in the striking state vibrate the casting area between the long wall plate 3 and the short wall plate 4 and the inner mold 9. When the innermost ends of the two sets of cam frames 133 rotate to the head positions of the two sets of push rod frames 134, the two sets of push rod frames 134, which lose the extrusion force, drive the two sets of vibration seats 136 and buffer pads 24 away from the long wall plate 3 and the short wall plate 4 under the elastic return action of the two sets of return springs 135. This process is repeated to continuously vibrate the casting area between the long wall plate 3 and the short wall plate 4 and the inner mold 9.Meanwhile, the long rotating shaft 124 drives the worm gear 141 to rotate synchronously with the planetary bevel gear 125. The worm gear 141 drives two sets of worm wheels 142 to rotate accordingly. The two sets of worm wheels 142 drive two reciprocating lead screws 143 to rotate accordingly. The two reciprocating lead screws 143 drive two sets of lead screw sleeves 144 to move horizontally back and forth. The two sets of lead screw sleeves 144 drive the hopper 27 to move in place with the base plate 1, rear wall plate 7, and long wall panel 3 through two sets of connecting seats 145. The short wall panel 4 and the inner mold 9 are horizontally displaced back and forth in the pouring area. The material prepared in advance in the hopper 27 is distributed into the two sets of distribution pipes 147 through two sets of four-way valves 146, and then uniformly and comprehensively distributed to the pouring area of ​​the spliced ​​base plate 1, back wall panel 7, long wall panel 3, short wall panel 4 and inner mold 9 by two rows of distribution heads 148. Combined with the two sets of vibrating seats 136 and buffer pads 24, the long wall panel 3 and the short wall panel 4 are continuously vibrated against the inner mold 9. Under the continuous vibration of the pouring area between molds 9, the material is forced to be evenly distributed in the pouring area. The material level sensor 28 monitors the material level in the hopper 27 in real time and replenishes it in a timely manner until the material distribution is completed. After a predetermined settling time, the precast concrete pouring in the pouring area of ​​the base plate 1, rear wall plate 7, long wall plate 3, short wall plate 4 and inner mold 9 is formed. Conversely, first control the double-head motor 101 to pause, then control the third electric push rod 123 to close and drive the driven bevel gear 122 to move upward and disengage from the meshing part of the drive bevel gear 121 to the initial position, stopping the knocking vibration of the two sets of vibrating seats 136 and the back-and-forth material distribution work of the hopper 27. Then, the long wall plate 3 and short wall plate 4 are successively separated and reset from the inner mold 9 from the base plate 1 and rear wall plate 7. After the formed precast concrete pouring is demolded and removed, this process is repeated to realize the modular production of several precast concrete pourings.
