Description

Technical Field

[0001] This invention relates to the field of prefabricated component manufacturing technology, and in particular to a production mold for a high-strength assembled composite slab. Background Technology

[0002] In prefabricated buildings, composite slabs are a common type of floor slab component. They consist of a precast base slab that is cured by pouring concrete grout and several steel trusses fixed to the precast base slab. They have the advantages of being quick to install and requiring no formwork.

[0003] In existing technologies, composite slabs are typically made by placing steel trusses on a fixed steel mold, then pouring concrete slurry, and allowing the concrete slurry to solidify. Although this type of casting mold and manufacturing method is widely used, the molds have poor versatility. The mold side plates are mostly fixed or simply spliced, which can only be spliced ​​together to form casting cavities of fixed sizes. This means that a production line can often only produce slabs of a single specification, which cannot meet the market's demand for multi-specification components. Increasing the cost of casting molds will lead to an increase in production and storage costs.

[0004] Therefore, it is necessary to improve the existing composite slab casting production molds. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects in the prior art and provide a production mold for high-strength prefabricated composite panels that can produce prefabricated base plates of various sizes to enhance versatility and reduce the cost increase caused by changing molds.

[0006] To achieve the above-mentioned technical effects, the technical solution of the present invention is: a production mold for a high-strength assembled composite plate, comprising: The pouring platform is fixed and its top surface is horizontal. The four surrounding components each include a mold strip horizontally attached to the top surface of the casting platform and a moving unit that drives the mold strip to move between the mold closing station and the mold separating station. The mold strips of the four surrounding components are two parallel longitudinal strips and two parallel transverse strips, respectively. The extension directions of the two longitudinal strips are perpendicular to the extension directions of the two transverse strips. The four mold strips at the separating station are spaced apart. At the mold closing station, in any two adjacent mold strips, the end face of one mold strip is sealed and attached to the side of the other mold strip, so that the four mold strips and the casting platform enclose a rectangular casting cavity. The length and width directions of the casting cavity are parallel to the extension directions of the longitudinal strips and the extension directions of the transverse strips, respectively. The movement direction of each mold strip includes a transverse direction parallel to the extension direction of the transverse strips and a longitudinal direction parallel to the extension direction of the longitudinal strips. A steel reinforcement mesh includes transverse reinforcement, longitudinal reinforcement, and a steel truss. The transverse reinforcement, longitudinal reinforcement, and steel truss are all arranged side by side in the horizontal direction. The transverse reinforcement is located between two longitudinal bars and extends parallel to the extension direction of the two transverse bars. The two ends of the longitudinal reinforcement are sealed and pass through two transverse bars and extend parallel to the extension direction of the two longitudinal bars. The steel truss is located between two transverse bars and extends parallel to the extension direction of the two longitudinal bars. The longitudinal reinforcement and the transverse reinforcement are both fixed above the transverse reinforcement.

[0007] Preferably, in order to facilitate flexible adjustment of the distribution quantity and spacing of longitudinal steel bars in the steel mesh according to the specific dimensions of the precast base plate, the crossbar is provided with a strip-shaped opening extending along its length direction, the two ends of the strip-shaped opening are adjacent to the two ends of the crossbar, and the strip-shaped opening is detachably filled with a foam strip that is compatible with it.

[0008] Preferably, to prevent the foam strips from sticking together during demolding, which would render them unusable and increase the cost of replacing them, the side of the strip opening closest to the casting cavity is covered with an anti-sticking film, which is connected to the foam strip.

[0009] Preferably, to facilitate the installation of the foam strip, the horizontal strip includes a bottom strip and a top strip that are distributed from bottom to top and are detachably connected. The top surface of the bottom strip is provided with a lower recess, and the bottom surface of the top strip is provided with an upper recess. The strip opening is formed by the combination of the lower recess and the upper recess.

[0010] Preferably, to facilitate the assembly of the horizontal bars, the bottom bar and the top bar are inserted together in the vertical direction.

[0011] Preferably, in order to ensure that the foam strip is securely installed between the top strip and the bottom strip, the dimensions of the two sides of the strip opening are larger than the dimensions of the middle of the strip opening along the extension direction parallel to the longitudinal strip.

[0012] Preferably, to prevent the foam strip from being deformed and damaged by the pressure of the concrete slurry, the crossbar also includes backing members that are spaced apart along its length and detachably connected to the bottom strip and the top strip, the backing members being fitted and connected to the side of the foam strip away from the pouring cavity.

[0013] Preferably, in order to limit the range of motion of the backrest and prevent it from detaching from the bottom strip and the top strip, the backrest slides along the length direction of the cross strip on the bottom strip and the top strip, and the backrest located at the end position is connected to a fastener, which is used to lock the corresponding backrest to the bottom strip and the top strip.

[0014] Preferably, to ensure the structural stability of the horizontal bar, both the bottom bar and the top bar are provided with a groove extending parallel to the length of the horizontal bar. The groove includes an inner space adjacent to the bottom of the groove and an outer space adjacent to the opening of the groove. The width of the inner space is smaller than the width of the outer space. The backing member includes an upper sliding part, a backing part, and a lower sliding part connected sequentially from top to bottom. The upper sliding part and the lower sliding part are respectively adapted to and slidably connected to the top bar groove and the bottom bar groove. The backing part is in contact with the side of the bottom bar, the top bar, and the foam bar away from the casting cavity.

[0015] Preferably, in order to facilitate demolding and support the steel mesh frame before production, a lifting assembly is provided on the casting platform. The lifting assembly includes a horizontal lifting plate and a lifting unit located below the lifting plate and driving the lifting plate to move in the vertical direction. The movement path of the lifting plate includes a support station. The longitudinal steel bars in the steel mesh frame placed under the support station are located between the planes of the top inner wall and the bottom inner wall of the strip opening.

[0016] In summary, compared with the prior art, the production mold of the high-strength assembled composite plate of the present invention drives the mold strips to move along their own length direction and perpendicular to their own length direction through the moving unit. This allows one end of any two adjacent mold strips to be sealed and connected to the mating surface of the other, forming an adjustable casting cavity. This enables the production of composite plates of different specifications without changing the mold, enhancing versatility while reducing the factory's equipment investment and warehousing costs.

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] like Figures 1-10 As shown, a production mold for a high-strength assembled laminated plate according to the present invention includes: Pouring platform 1 is fixedly installed and its top surface is horizontal; The four surrounding components each include a mold strip 2 that is horizontally attached to the top surface of the casting platform 1 and a moving unit 3 that drives the mold strip 2 to move between the mold closing station and the mold separating station. The mold strip 2 of the four surrounding components are two parallel longitudinal bars 5 and two parallel transverse bars 6, respectively. The extension direction of the two longitudinal bars 5 is perpendicular to the extension direction of the two transverse bars 6. The four mold strips 2 at the separating station are spaced apart. At the mold closing station, in two adjacent mold strips 2, the end face of one mold strip 2 is sealed and attached to the side of the other mold strip 2, so that the four mold strips 2 and the casting platform 1 enclose a rectangular casting cavity. The length direction and width direction of the casting cavity are parallel to the extension direction of the longitudinal bars 5 and the extension direction of the transverse bars 6, respectively. The movement direction of each mold strip 2 includes a transverse direction parallel to the extension direction of the transverse bars 6 and a longitudinal direction parallel to the extension direction of the longitudinal bars 5. The steel reinforcement mesh 4 includes transverse steel bars 41, longitudinal steel bars 42, and steel truss 43. The transverse steel bars 41, longitudinal steel bars 42, and steel truss 43 are all arranged side by side in the horizontal direction. The transverse steel bars 41 are located between two longitudinal bars 5 and extend in a direction parallel to the extension direction of the two transverse bars 6. The two ends of the longitudinal steel bars 42 are sealed and pass through the two transverse bars 6 and extend in a direction parallel to the extension direction of the two longitudinal bars 5. The steel truss 43 is located between two transverse bars 6 and extends in a direction parallel to the extension direction of the two longitudinal bars 5. The longitudinal steel bars 42 and the transverse steel bars 41 are both fixed above the transverse steel bars 41.

[0020] When using this production mold, firstly, a steel mesh frame 4 is prepared. Based on the specific dimensions and structure of the composite slab, the distribution quantity and spacing of the transverse steel bars 41, longitudinal steel bars 42, and steel truss 43 in the steel mesh frame 4 are determined. After the transverse steel bars 41, longitudinal steel bars 42, and steel truss 43 are tied and fixed together with steel wire, the prepared steel mesh frame 4 is placed above the pouring platform 1 and fixed. Then, the positions of the four mold strips 2 are adjusted by the moving unit 3 so that after the four mold strips 2 move to the mold closing position, any two adjacent mold strips... In section 2, the end of one formwork strip 2 is sealed and fitted to the side of another formwork strip 2, so that the four formwork strips 2 cooperate with the pouring platform 1 to form a rectangular pouring cavity. The length direction of the pouring cavity is parallel to the length direction of the longitudinal strip 5, and the width direction is parallel to the length direction of the transverse strip 6. In the steel mesh 4, the transverse steel bars 41 are aligned with the length direction of the transverse strip 6, and the length directions of the longitudinal steel bars 42 and the steel truss 43 are aligned with the length direction of the longitudinal strip 5. At the same time, the bottom of the transverse steel bars 41 and the steel truss 43 is located inside the pouring cavity. The top of the steel truss 43, i.e., the upper chord reinforcement, is located above the opening of the casting cavity. The longitudinal reinforcement 42 seals and penetrates the two transverse bars 6. Based on this, a hydraulic press or jack is used to apply pressure to both ends of the longitudinal reinforcement 42 to stretch it and keep it in a state of tension deformation. Concrete grout is poured into the casting cavity so that the surface of the concrete grout covers the transverse reinforcement 41, the longitudinal reinforcement 42, and the lower chord reinforcement of the steel truss 43, until the grout surface is flush with the top surfaces of the transverse bars 6 and the longitudinal bars 5. After the concrete grout has solidified and formed... After the precast base plate is fixedly connected to the steel mesh frame 4, the tensile deformation of the longitudinal steel bars 42 is removed, so that the cured concrete precast base plate can maintain the tension of the longitudinal steel bars 42 to enhance the product's resistance to shear. The transverse steel bars 41 and steel truss 43 enhance the product's structural strength and extend its service life. Then, the four mold strips 2 are adjusted to the separation position by the four moving units 3, so that the four mold strips 2 are separated from each other. The composite plate formed by the steel mesh frame 4 and the precast base plate can then be taken out.

[0021] In this invention, the moving unit 3 can drive the corresponding mold strip 2 to move horizontally and vertically, and the moving direction of the mold strip 2 is always horizontal, so that the bottom surface of the mold strip 2 is sealed and fitted with the top surface of the casting platform 1. After the four mold strips 2 move to the mold closing position, in any two adjacent mold strips 2, the end of one mold strip 2 is sealed and fitted with the mold closing surface 202 of the other mold strip 2. In this way, it is convenient to adjust and control the relative position of the four mold strips 2 when the mold is closed according to different production needs, thereby adjusting the length and width of the enclosed casting cavity, and thus enabling the production of precast base plates with different length and width dimensions. While meeting different production needs, it significantly enhances versatility, eliminating the need to change molds. On the one hand, it reduces the equipment investment caused by the factory needing to prepare different molds; on the other hand, it eliminates the need for the factory to prepare multiple molds, thereby reducing the storage space of molds and thus reducing storage investment.

[0022] To enable the moving unit 3 to drive the corresponding mold strip 2 to move horizontally and vertically, in this invention, the casting platform 1 is a horizontal rectangular plate structure, with a support frame 11 fixed to its bottom. The support frame 11 is fixed to the ground, such as... Figures 5-11 As shown, the moving unit 3 includes a first moving mechanism 31 and a second moving mechanism 32. The output end of the first moving mechanism 31 is connected to the second moving mechanism 32 to drive the second moving mechanism 32 to move along a direction perpendicular to the length of the corresponding mold strip 2. The output end of the second moving mechanism 32 is connected to the corresponding mold strip 2 to drive the mold strip 2 to move along a direction parallel to its own length. Thus, by having the first moving mechanism 31 drive the mold strip 2 to move along a direction perpendicular to its own length, and by having the second moving mechanism 32 drive the mold strip 2 to move along a direction parallel to its own length, the mold strip 2 has two directions of movement. This allows for adjustment of the relative positions of the four mold strips 2 according to different production needs. When the mold is closed, the end of one of two adjacent mold strips 2 is in contact with the side of the other mold strip 2 to form a casting cavity with different length and width dimensions, thus meeting different production requirements.

[0023] Specifically, in this invention, the first moving mechanism 31 includes a first moving motor 311, a first screw 312, a moving screw sleeve 313, a moving plate 314, a guide rod 315, a guide sleeve 316, and a first distance sensor 317. The first moving motor 311 is fixed to the casting platform 1, with its output end facing the side of the mold strip 2. The output end of the first moving motor 311 is coaxially connected to the first screw 312, and the axial direction of the first screw 312 is perpendicular to the length direction of the corresponding mold strip 2. Sleeve 313 is threaded onto the outside of the first screw 312. Movable plate 314 extends along the length direction parallel to the mold strip 2 and is fixed to the end of movable sleeve 313 away from the first moving motor 311. Guide rod 315 extends along the axial direction parallel to the first screw 312 and is fixedly connected to movable plate 314. Guide sleeve 316 is fixed to one side of the first moving motor 311. Guide rod 315 slides through the inside of guide sleeve 316. First distance sensor 317 is fixed on pouring platform 1 and faces movable plate 314.

[0024] The second moving mechanism 32 includes a second moving motor 321, a second screw 322, a bushing 323, a moving block 324, and a second distance sensor 325. For the longitudinal bar 5, two clamping plates 51 extending along its length and arranged side by side along its height are provided on its side away from the casting cavity. For the transverse bar 6, a moving seat 612 is fixed to the bottom of its side away from the casting cavity. The second moving motor 321 and the bushing 323 are respectively fixed to the two ends of the moving plate 314 on the side away from the first moving motor 311. One end of the second screw 322 is fixedly connected to the output end of the second moving motor 321 along the same axis, and the other end rotates around its own axis inside the bushing 323. The moving block 324 is sleeved on the outside of the second screw 322 and is connected to the second screw 322. The second screw 322 is threadedly connected. The moving block 324 has an integrally formed clamping groove 3241. The clamping groove 3241 slides on the moving plate 314 along the length direction parallel to the mold strip 2. The second distance sensor 325 is fixed on the bushing 323 and faces the moving block 324. The moving block 324 corresponding to the longitudinal strip 5 is attached between the driving surface 201 and the two clamping strips 207. The moving block 324 is fixedly connected to the two second clamping strips 207 by threaded fastening bolts 326 and fastening nuts 327. The top and bottom surfaces of the moving block 324 are respectively attached to the two second clamping strips 207. The two ends of the moving block 324 corresponding to the transverse strip 6 are respectively fixedly connected to the two ends of the moving seat 612 by two fastening bolts 326.

[0025] With the above structure, the first moving motor 311 starts and drives the first screw 312 to rotate. Under the sliding cooperation of the guide rod 315 and the guide sleeve 316, the moving screw sleeve 313 moves along the axial direction parallel to the first screw 312. Then, through the moving plate 314 and the second moving mechanism 32, it acts on the mold strip 2, driving the mold strip 2 to move in the horizontal direction parallel to the axial direction of the first screw 312, that is, perpendicular to its own length direction. The moving distance position of the moving plate 314 can be easily monitored by the first distance sensor 317, thereby accurately controlling the moving position of the mold strip 2 in the horizontal direction perpendicular to its own length direction.

[0026] After the second moving motor 321 is started, it drives the second screw 322 to rotate around its own axis under the support of the bushing 323. Through the sliding engagement of the clamping groove 3241 and the moving plate 314, the moving block 324 moves along the axial direction parallel to the second screw 322, thereby driving the mold strip 2 to move along the direction parallel to its own length. The moving distance position of the moving block 324 can be detected by the second distance sensor 325, thereby accurately controlling the moving position of the mold strip 2 along the direction parallel to its own length.

[0027] For the longitudinal bar 5, the movable block 324 is detachably and fixedly connected to the two clamping strips 207 attached to its top and bottom surfaces by threaded fastening bolts 326 and fastening nuts 327, thereby realizing the detachable connection between the output end of the movable unit 3 and the longitudinal bar 5, which facilitates the replacement of the longitudinal bar 5; for the transverse bar 6, the two ends of the movable block 324 are fixedly connected to the two ends of the movable seat 612 by two fastening bolts 326 respectively, and the movable seat 612 is fixedly connected to the transverse bar 6. In this way, the detachable connection between the output end of the movable unit 3 and the transverse bar 6 is realized, which facilitates the replacement of the transverse bar 6.

[0028] A further improvement is that the horizontal bar 6 is provided with a strip-shaped opening extending along its length, the two ends of the strip-shaped opening being close to the two ends of the horizontal bar 6, and the strip-shaped opening being detachably filled with a foam strip 63 that is compatible with it.

[0029] With the above structure, by setting a strip-shaped opening on the crossbar 6, and detachably connecting a foam strip 63 to fill the opening, the foam strip 63 moves relative to the steel mesh 4 during the movement of the crossbar 6 driven by the moving unit 3. The relative movement direction is parallel to the longitudinal steel bar 42, so that the foam strip 63 can be sealed and fitted onto the longitudinal steel bar 42. This facilitates the stretching treatment of the longitudinal steel bar 42 after it passes through the foam strip 63. Thus, for longitudinal steel bars 42 with the same distribution interval and quantity in the same batch, the same foam strip 63 can be used. For longitudinal steel bars 42 with different distribution intervals and quantities in different batches, the foam strip 63 can be replaced before mold closing treatment, so that the ends of the longitudinal steel bars 42 pass through the foam strip 63 to form perforations, which is convenient for use on products with the same distribution interval and quantity.

[0030] A further improvement is that the side of the strip opening closest to the casting cavity is covered with an anti-sticking membrane 67, which is connected to the foam strip 63.

[0031] With this structure, after the concrete slurry has solidified and formed into a precast base plate, the precast base plate is connected to the anti-sticking membrane 67, so that when the product is demolded and removed, the anti-sticking membrane 67 is detached from the foam strip 63, avoiding the precast base plate from sticking to the foam strip 63 during demolding, which would cause damage to the foam strip 63.

[0032] In practical applications, the anti-stick film 67 is preferably a PE film or a PET film, which covers the front of the strip opening. A layer of water-based release agent can be applied to the anti-stick film 67 to facilitate connection with the foam strip 63, while also isolating the concrete slurry from the foam strip 63. This prevents the concrete slurry from sticking together after contact with the foam strip 63 due to curing, thus avoiding damage to the foam strip 63 during demolding as it moves with the product.

[0033] A further improvement is that the horizontal bar 6 includes a bottom bar 61 and a top bar 62 that are distributed from bottom to top and are detachably connected. The top surface of the bottom bar 61 is provided with a lower recess 611, and the bottom surface of the top bar 62 is provided with an upper recess 621. The strip-shaped opening is formed by the combination of the lower recess 611 and the upper recess 621.

[0034] In this invention, the bottom strip 61 is fixedly connected to the movable seat 612. After the foam strip 63 is installed on the lower recess 611 of the bottom strip 61, the top strip 62 is installed above the bottom strip 61, so that the upper recess 621 of the top strip 62 and the lower recess 611 of the bottom strip 61 combine to form a strip-shaped opening that is compatible with the foam strip 63.

[0035] A further improvement is that the bottom strip 61 and the top strip 62 are inserted together in the vertical direction.

[0036] This structure facilitates quick assembly and connection between the bottom strip 61 and the top strip 62. Specifically, the bottom strip 61 has inserts 613 extending vertically upwards at both ends, and the top strip 62 has through holes 622 extending vertically at both ends. The inner diameter of the through holes 622 is the same as the outer diameter of the inserts 613, which allows the top strip 62 to be sealed and fitted onto the inserts 613 at both ends of the bottom strip 61, thus achieving precise docking between the bottom strip 61 and the top strip 62.

[0037] A further improvement is that, along the extension direction parallel to the longitudinal strip 5, the dimensions of the two sides of the strip opening are larger than the dimensions of the middle part of the strip opening.

[0038] With this structure, the foam strip 63 can be positioned to prevent it from shifting in position along the length of the longitudinal strip 5, ensuring that the foam strip 63 is accurately installed between the bottom strip 61 and the top strip 62. It can also withstand the squeezing force of the concrete slurry in the pouring cavity and prevent it from moving away from the pouring cavity.

[0039] A further improvement is that the crossbar 6 also includes backing members 64 that are spaced apart along its length and detachably connected to the bottom bar 61 and the top bar 62, the backing members 64 being fitted and connected to the side of the foam bar 63 away from the pouring cavity.

[0040] With this structure, the backing member 64 is attached to the side of the foam strip 63 away from the pouring cavity. When concrete slurry is injected into the pouring cavity, the concrete slurry applies pressure to the foam strip 63, which then transmits the pressure to the backing member 64 for support, preventing damage, deformation, or deviation of the foam strip 63 from the pouring cavity. The backing member 64 is detachably connected to the bottom strip 61 and the top strip 62, and is distributed along the length of the horizontal strip 6. Therefore, the backing member 64 installed on the horizontal strip 6 can be adjusted according to the number and spacing of the longitudinal reinforcing bars 42 in the steel mesh frame 4. This allows the backing member 64 to support the foam strip 63 while providing clearance for the longitudinal reinforcing bars 42, facilitating their penetration through the foam strip 63. Multiple backing members 64 provide back support, increasing support nodes and ensuring the lifespan and number of uses of the foam strip 63.

[0041] A further improvement is that the backrest 64 slides along the length of the crossbar 6 on the bottom bar 61 and the top bar 62. The backrest 64 at the end is connected to a fastener 65, which is used to lock the corresponding backrest 64 to the bottom bar 61 and the top bar 62. The bottom bar 61 and the top bar 62 are both provided with a groove 66 extending parallel to the length of the crossbar 6. The groove 66 has an inner space adjacent to the bottom of the groove and an outer space adjacent to the opening of the groove. The width of the inner space is smaller than the width of the outer space. The backrest 64 includes an upper sliding part 641, a backrest part 642 and a lower sliding part 643 connected sequentially from top to bottom. The upper sliding part 641 and the lower sliding part 643 are adapted to and slidably connected to the groove 66 of the top bar 62 and the groove 66 of the bottom bar 61, respectively. The backrest part 642 is attached to the side of the bottom bar 61, the top bar 62 and the foam bar 63 away from the pouring cavity.

[0042] Specifically, the cross-sectional shape of the groove 66 is L-shaped, and the groove 66 is a through groove. In the fastener 65, the upper sliding part 641, the backing part 642, and the lower sliding part 643 are integrally connected from top to bottom. The grooves 66 of the bottom strip 61 and the grooves 66 of the top strip 62 are radially symmetrically distributed, which facilitates the upper sliding part 641 and the lower sliding part 643 of the fastener 65 to slide into the two grooves 66. The two backing parts 64 located at the end positions are corresponding to two locking bolts in the fastener 65. The two locking bolts are fixedly connected to the bottom strip 61 and the top strip 62 respectively. The side of the top strip 62 away from the casting cavity is provided with scale lines 623 distributed at intervals along its length direction. The scale lines 623 make it easy to determine the relative position of the backing parts 64 on the crossbar 6.

[0043] After adopting the above structure, when assembling the crossbar 6, first install the foam strip 63 onto the bottom strip 61, and then place the top strip 62 on the foam strip 63, so that the sleeve hole 622 of the top strip 62 is sealed onto the insert 613 of the bottom strip 61. Based on the distribution quantity and spacing of the longitudinal steel bars 42 in the composite slab to be produced, determine the required backing member 64. Slide the upper sliding part 641 and the lower sliding part 643 of the backing member 64 into the grooves 66 of the top strip 62 and the bottom strip 61 respectively, with the backing part 642 adhering to the foam strip 63. Adjust... The well-positioned backing member 64 facilitates the longitudinal steel bar 42 passing through the foam strip 63 and separated from the backing member 64. In the two backing members 64 at the end positions, the bottom strip 61 and the top strip 62 are firmly connected by tightening the locking bolts. The backing parts 642 on the multiple backing members 64 are connected to the upper sliding part 641 and the lower sliding part 643 respectively, acting on the inner wall of the two sliding grooves 66 to prevent the bottom strip 61 and the top strip 62 from separating, further ensuring the firm connection between the bottom strip 61 and the top strip 62, thereby enhancing the structural stability of the horizontal strip 6.

[0044] A further improvement is that a lifting assembly 7 is provided on the pouring platform 1. The lifting assembly 7 includes a horizontal lifting plate 71 and a lifting unit 72 located below the lifting plate 71 and driving the lifting plate 71 to move in the vertical direction. The movement path of the lifting plate 71 includes a support position. The longitudinal steel bars 42 in the steel mesh frame 4 placed under the support position are located between the planes of the top inner wall and the bottom inner wall of the strip opening.

[0045] After adopting the above structure, before placing the steel mesh frame 4, the position of the horizontal bar 6 is adjusted by the second moving mechanism 32, and the lifting unit 72 is activated to raise the lifting plate 71 to the support position. The lifting plate 71 is located between the four templates 2. The steel mesh frame 4 is placed on the lifting plate 71 so that the longitudinal steel bars 42 in the steel mesh frame 4 can be aligned with the foam strip 63 in the strip opening to fix the steel mesh frame 4 (the fixing method can be manually or by other tools to lock the steel mesh frame 4 onto the lifting plate 71, which will not be described in detail here). Then, the first moving mechanism 31 in the moving unit 3 drives the horizontal bar 6 to move along the length direction parallel to the longitudinal bar 5 so that the longitudinal steel bars 42 can pass through the foam strip 63.

[0046] After adjusting the positions of the four formwork strips 2, the lifting plate 71 is lowered, the longitudinal steel bar 42 is pulled by rope, and concrete slurry is poured. After the concrete slurry has solidified, the moving unit 3 drives the formwork strip 2 to move horizontally along its own length to the mold separation position. Then the lifting unit 72 drives the lifting plate 71 to rise, so that the composite plate is separated from the top surface of the pouring platform 1, making it easy to demold and remove the product.

[0047] Specifically, a recess 12 is provided at the center of the pouring platform 1, located between the four mold strips 2. The movement path of the lifting plate 71 also includes a sealing station located at the support station. Under the sealing station, the top surface of the lifting plate 71 is on the same horizontal plane as the top surface of the pouring platform 1, and the outer circumferential edge of the lifting plate 71 is sealed and fitted to the inner circumferential wall of the recess 12. The lifting unit 72 is a lifting cylinder, whose cylinder is fixed on the ground. The top of the piston rod is fixedly connected to the center of the bottom surface of the lifting plate 71. The lifting plate 71 is a rectangular plate, and guide shafts 73 extending vertically and sliding through the pouring platform 1 are fixed at the bottom of its four corners to ensure that the lifting plate 71 can move smoothly in the vertical direction when the lifting cylinder is running.

[0048] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
