Description

Technical Field

[0001] This invention relates to the field of precast slab production technology, specifically to a combined anti-loosening device for a precast composite slab casting mold. Background Technology

[0002] Precast composite slabs are concrete floor slabs that are manufactured and processed in a prefabrication yard, transported to the construction site by transportation equipment, and then installed and used. Casting molds are tools used to make concrete components, usually made of steel plates, wooden boards or other materials. Their function is to provide a template with a stable shape and size for the concrete during the concrete pouring process, so as to ensure that the concrete components produced meet the design requirements. The production of precast composite slabs requires the use of casting molds for shaping.

[0003] When using casting molds, they need to be reinforced with anti-loosening components to prevent the molds from shifting or loosening during the casting process, which could cause the poured concrete to leak out. Existing anti-loosening components consist of fasteners and bolts. During use, each fastener is clamped at each connection point of the mold and fixed to the base plate below the mold with bolts. Since the precast composite slabs need to be demolded after curing, the fasteners and mold plates need to be disassembled one by one after each precast composite slab is made. The use of existing anti-loosening devices makes the installation, disassembly, and reinforcement of the molds cumbersome and inconvenient for the rapid production of precast composite slabs. In addition, due to the certain adhesive force between the precast composite slabs and the mold, and the fact that the mold plate has a single stress point, it is difficult to disassemble the mold plate and make it inconvenient to demold the precast composite slabs.

[0004] To address this, a combined anti-loosening device for precast composite slab casting molds is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a combined anti-loosening device for precast composite slab casting molds to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a combined anti-loosening device for a precast composite slab casting mold, comprising a base plate, on the top of which a transverse mold plate and a longitudinal mold plate are placed, with two of each type of mold plate being provided.

Two fixing plates are fixedly connected to one side of each of the two transverse support plates close to each other. A first push rod is rotatably connected to one end of each of the four fixing plates away from the transverse support plates. Two first push rods are configured as a pair, and a limiting member is rotatably connected between each pair of first push rods. A second push rod is rotatably connected to one side of each of the two mounting blocks inside one transverse support plate close to each other. A connecting block is rotatably connected between the two ends of the two second push rods close to each other. A threaded rod is threadedly connected inside the connecting block and rotatably connected to the transverse support plate. Another limiting member is fixedly connected to one end of the threaded rod close to the longitudinal mold plate. Support springs are fixedly connected to the top and bottom of the inner wall of the limiting member. Clamping plates are fixedly connected to the ends of the two support springs close to each other. A cam is rotatably connected inside the limiting member and is located between the two clamping plates.

[0009] Preferably, a T-shaped groove is provided on the side of the vertical rack near the longitudinal mold plate, and the end of the sleeve near the vertical rack is embedded in the T-shaped groove and fixedly connected to the T-shaped groove by bolts.

[0010] Preferably, a threaded post is fixedly connected to the top of the movable plate, and the movable plate is fixedly connected to the sleeve through the threaded post and nut. The transverse rack is U-shaped, the transverse rack is perpendicular to the vertical rack, and the width between the inner walls of the transverse rack is the same as the width of the vertical rack.

[0011] Preferably, the four fixing blocks are respectively embedded inside the end faces of the two transverse mold plates, and the bottom of the longitudinal support block is set as an inclined surface on the side near the transverse mold plate.

[0012] Preferably, the second pin is fixed to the connecting clamp by bolts, the length of the second pin is two to four times that of the first pin, the second pin is T-shaped and the top and bottom near the outer end of the limiting member are both set as bevels.

[0013] Preferably, the clamping plate is L-shaped, and the two clamping plates inside the limiting member are arranged opposite each other.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] Firstly, the device reinforces the longitudinal and transverse mold plates with transverse support plates and longitudinal support blocks respectively, effectively preventing stress shifting and loosening of the transverse and longitudinal mold plates during the pouring of precast composite slabs. This prevents concrete from leaking between the transverse and longitudinal mold plates, facilitating the production of precast composite slabs and preventing concrete waste. Furthermore, the device automatically reinforces the transverse and longitudinal mold plates via a motor drive. The movement of the transverse support plates can also simultaneously drive the movement of the longitudinal support blocks, improving the automation level of the device and making its operation and use simpler and more convenient, thus accelerating the production speed of precast composite slabs.

[0017] Secondly, the height and horizontal position of the longitudinal support blocks can be adjusted, making the device suitable for different heights and widths of transverse and longitudinal mold plates, thus expanding its application range. Furthermore, the spacing between the two transverse support plates and the two mounting blocks can also be adjusted, enabling the device to be used for the production of precast composite slabs of different specifications. This further expands the device's application range and improves its applicability, making it convenient for practical use.

[0018] Thirdly, after the precast composite slab hardens, manually controlling the motor output shaft to rotate in the opposite direction can drive the horizontal and vertical mold plates to open, allowing them to detach from the edges of the precast composite slab, facilitating demolding. This design enables automatic demolding during the production of precast composite slabs, solving the problem of the horizontal and vertical mold plates having a single stress point and being inconvenient for disassembly and demolding. It also saves manpower and improves the production efficiency of precast composite slabs. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0032] Please see Figures 1 to 8 As shown, one embodiment of the present invention provides a combined anti-loosening device for a precast composite slab casting mold, comprising a base plate 1, a transverse mold plate 11 and a longitudinal mold plate 12 placed on the top of the base plate 1, two of each of the transverse mold plate 11 and the longitudinal mold plate 12 are provided, the transverse mold plate 11 and the longitudinal mold plate 12 are perpendicular to each other and surround a rectangular space, a reinforcing mechanism for fastening the transverse mold plate 11 and the longitudinal mold plate 12 is provided on the top of the base plate 1, and a disassembly mechanism for disassembling the transverse mold plate 11 and the longitudinal mold plate 12 is provided inside the reinforcing mechanism;

[0033] The reinforcement mechanism includes a motor 201, which is fixedly connected to the outside of the base plate 1. Two bidirectional lead screws 202 are rotatably connected to the top of the base plate 1. One of the bidirectional lead screws 202 is fixedly connected to the output shaft of the motor 201. A transmission component 203 is meshed between the two bidirectional lead screws 202 and is rotatably connected to the top of the base plate 1. Two transverse support plates 204 are threaded between the two bidirectional lead screws 202. Two mounting blocks 205 are slidably connected inside one of the transverse support plates 204.

A fixing frame 206 is fixedly connected to the side of the mounting block 205 away from the longitudinal mold plate 12. A transverse rack 217 is slidably connected to the bottom of the mounting block 205. 08. A return spring 207 is fixedly connected between the transverse rack 208 and the fixed frame 206. A vertical rack 209 is slidably connected to the side of the mounting block 205 near the longitudinal mold plate 12. A sleeve 210 is fixedly connected to the side of the vertical rack 209 near the longitudinal mold plate 12. A movable plate 211 is fixedly connected inside the sleeve 210. A longitudinal support block 212 is fixedly connected to the bottom of the movable plate 211. A lower toothed roller 215 and an upper toothed roller 216 are rotatably connected inside the mounting block 205. The lower toothed roller 215 and the upper toothed roller 216 are respectively meshed with the transverse rack 208 and the vertical rack 209. A transmission disc 213 is fixedly connected to the outer end of the lower toothed roller 215 and the upper toothed roller 216. A transmission belt 214 is connected to the outside of the two transmission discs 213.

[0034] Furthermore, the disassembly mechanism includes two first pins 301, which are fixedly connected to the opposite sides of the two longitudinal mold plates 12. Connecting clamps 302 are fixedly connected to the opposite sides of the two transverse mold plates 11. Second pins 303 are fixedly connected inside the two connecting clamps 302. Two fixing plates 304 are fixedly connected to the adjacent sides of the two transverse support plates 204. First push rods 305 are rotatably connected to the ends of the four fixing plates 304 away from the transverse support plates 204. Two first push rods 305 are configured as a pair, and a limiter 306 is rotatably connected between each pair of first push rods 305. A transverse support... Two mounting blocks 205 inside plate 204 are rotatably connected to a second push rod 307 on their adjacent sides. A connecting block 308 is rotatably connected between the adjacent ends of the two second push rods 307. A threaded rod 309 is threadedly connected inside the connecting block 308. The threaded rod 309 is rotatably connected to the transverse support plate 204. Another limiting member 306 is fixedly connected to the end of the threaded rod 309 near the longitudinal mold plate 12. Support springs 310 are fixedly connected to the top and bottom of the inner wall of the limiting member 306. Clamping plates 311 are fixedly connected to the adjacent ends of the two support springs 310. A cam 312 is rotatably connected inside the limiting member 306. The cam 312 is located between the two clamping plates 311.

[0035] Furthermore, a T-shaped groove is provided on the side of the vertical rack 209 near the longitudinal mold plate 12. The end of the sleeve 210 near the vertical rack 209 is embedded in the T-shaped groove and fixedly connected to the T-shaped groove by bolts. The sleeve 210 can slide inside the T-shaped groove to achieve height adjustment. After the height adjustment is completed, the sleeve 210 is fixed to the vertical rack 209 by bolts.

[0036] Furthermore, a threaded post is fixedly connected to the top of the movable plate 211. The movable plate 211 is fixedly connected to the sleeve 210 through the threaded post and nut, so that the length of the movable plate 211 extending from the inside of the sleeve 210 can be adjusted to realize the adjustment of the horizontal position of the movable plate 211, which facilitates the movable plate 211 to support the transverse mold plate 11. The transverse rack 208 is U-shaped and perpendicular to the vertical rack 209. The width between the inner walls of the transverse rack 208 is the same as the width of the vertical rack 209. Its function is to ensure that the transverse rack 208 does not obstruct the downward movement of the vertical rack 209.

[0037] Furthermore, four fixing blocks 217 are respectively embedded inside the end faces of the two transverse mold plates 11. The clamping of the transverse mold plates 11 by the fixing blocks 217 and the longitudinal support blocks 212 can make the transverse mold plates 11 firmly fixed, preventing the connection between the transverse mold plates 11 and the longitudinal mold plates 12 from loosening. The bottom of the longitudinal support block 212 is set as an inclined surface on the side near the transverse mold plate 11. Its function is to push the transverse mold plate 11 when the longitudinal support block 212 descends under certain error conditions, so as to avoid the transverse mold plate 11's positional error from hindering the descent of the longitudinal support block 212.

[0038] Furthermore, the second pin 303 is fixed to the connecting clamp 302 by bolts. The length of the second pin 303 is two to four times that of the first pin 301. The second pin 303 is T-shaped and the top and bottom near the outer end of the limiting member 306 are both set as bevels, so that the second pin 303 can automatically push open and insert between the two clamping plates 311.

[0039] Furthermore, the clamping plate 311 is L-shaped, and the two clamping plates 311 inside the limiting member 306 are arranged opposite each other. The length of the clamping plate 311 located on the side of the two transverse mold plates 11 that is far away from each other is two to four times the length of the other clamping plates 311. The purpose of this design is to enable the transverse support plate 204 to move first through the clamping plate 311 and the first pin 301 when the transverse mold plate 11 and the longitudinal mold plate 12 are disassembled, so that the longitudinal mold plate 12 is disassembled first. During this process, the second pin 303 slides between the clamping plates 311. The clamping plate 311 does not pull the second pin 303 and the transverse mold plate 11. After the longitudinal mold plate 12 is disassembled, the transverse support plate 204 moves and drives the longitudinal support block 212 to move, so that the longitudinal support block 212 is no longer supported on the outside of the transverse mold plate 11. At this time, the clamping plate 311 pulls the second pin 303 so that the transverse mold plate 11 is successfully disassembled.

[0040] Furthermore, the outer end of the cam 312 passes through the limiting member 306 and extends to the outside of the limiting member 306, making it easy to rotate manually. The top and bottom of the cam 312 are in contact with the clamping plate 311. During the rotation of the cam 312, it can drive the two clamping plates 311 to move away from each other, making it easy to remove the first pin 301 or the second pin 303 from between the clamping plates 311.

[0041] Working principle: In the initial state, the support spring 310 is in a compressed state, the opposite ends of the two clamping plates 311 located inside the same limiting member 306 are in contact, and the distance between the two mounting blocks 205 inside the same transverse support plate 204 is at its maximum.

[0042] Before use, the transverse mold plate 11 and the longitudinal mold plate 12 are manually placed on top of the base plate 1 and vertically spliced ​​together so that each fixing block 217 fixed on the outside of the longitudinal mold plate 12 is embedded in the end face of the transverse mold plate 11. At this time, the transverse mold plate 11 and the longitudinal mold plate 12 form a rectangular space. The transverse mold plate 11 and the longitudinal mold plate 12 are manually pushed so that they are centered between the two bidirectional lead screws 202 and the two transverse support plates 204. Then, the extension length of the movable plate 211 from the sleeve 210 is manually adjusted according to the height and width of the longitudinal mold plate 12. The height of the sleeve 210 fixed on the vertical rack 209 is adjusted. After adjustment, the sleeve 210 and the movable plate 211, and the sleeve 210 and the vertical rack 209 are fixed by nuts and bolts respectively. The height and horizontal position of the longitudinal support block 212 can be adjusted, so that the device can be used for different heights and widths of the transverse mold plate 11 and the longitudinal mold plate 12, which expands the application range of the device and improves its applicability, making it convenient for actual use.

[0043] The threaded rod 309 is manually turned, and the rotation of the threaded rod 309 causes the connecting block 308 to move away from the transverse support plate 204. The movement of the connecting block 308 pulls the second push rod 307, which in turn pulls the mounting block 205 rotatably connected to it toward the direction of the connecting block 308. This causes the two mounting blocks 205 to slide toward each other inside the transverse support plate 204. The movement of the mounting blocks 205 causes the sleeve 210, the movable plate 211, and the longitudinal support block 212 to move until the distance between the longitudinal support blocks 212 is the same as the distance between the two transverse mold plates 11 on the side that is away from each other.

[0044] The motor 201 is manually started, and the output shaft of the motor 201 rotates, causing the fixed bidirectional lead screw 202 to rotate. The rotation of the bidirectional lead screw 202 drives the transmission component 203 to rotate, which in turn drives another bidirectional lead screw 202 to rotate, making the two bidirectional lead screws 202 rotate synchronously. The synchronous rotation of the two bidirectional lead screws 202 causes the two transverse support plates 204 to move towards each other. The movement of the transverse support plates 204 causes the mounting block 205 to move, and the movement of the mounting block 205 causes the transverse rack 208 to move. After the rack 208 moves to contact the longitudinal mold plate 12, it continues to move. At this time, under the pressure of the longitudinal mold plate 12, with the mounting block 205 as a reference, the transverse rack 208 moves towards the fixed frame 206, the return spring 207 is compressed, and the movement of the transverse rack 208 drives the lower toothed roller 215 to rotate. The rotation of the lower toothed roller 215 drives the transmission disc 213 fixed to it to rotate. Under the transmission action of the transmission belt 214, the rotation of the transmission disc 213 drives the other transmission disc 213 to rotate, thereby causing the transmission discs to rotate. The rotation of 213 drives the upper toothed roller 216 to rotate, which in turn drives the vertical rack 209 to move downward. The downward movement of the vertical rack 209 drives the sleeve 210 and the movable plate 211 to move downward. The downward movement of the movable plate 211 drives the longitudinal support block 212 to move downward. The downward movement of the movable plate 211 contacts the outer side of the transverse mold plate 11 to support the transverse mold plate 11. This device supports and reinforces the longitudinal mold plate 12 and the transverse mold plate 11 respectively through the transverse support plate 204 and the longitudinal support block 212, effectively preventing the transverse mold plate 11 and the longitudinal mold plate 12 from shifting under stress and loosening during the pouring process of the precast composite slab. This prevents concrete from leaking out between the transverse mold plate 11 and the longitudinal mold plate 12, facilitating the production of precast composite slabs and preventing concrete waste. Furthermore, the movement of the transverse support plate 204 can simultaneously drive the movement of the longitudinal support block 212, improving the automation level of the device and making its operation and use simpler and more convenient, thus accelerating the production speed of precast composite slabs.

[0045] As the transverse support plate 204 moves toward the longitudinal mold plate 12, it drives the limiting member 306 fixed thereto to move toward the longitudinal mold plate 12. The movement of the limiting member 306 drives the clamping plate 311 inside it to move toward the longitudinal mold plate 12. After the clamping plate 311 contacts the first pin 301, the clamping plate 311 continues to move toward the longitudinal mold plate 12. At this time, the first pin 301 inserts between the two clamping plates 311 and engages with the two clamping plates 311. The two clamping plates 311 move away from each other, and the support spring 310 is further compressed. At the same time, the relative movement of the two transverse support plates 204 drives the relative movement of the two pairs of fixed plates 304. The relative movement of the two pairs of fixed plates 304 pushes the two pairs of first push rods 305, so that the first push rods 305 push the limiting member 306 rotatably connected thereto toward the direction of the transverse mold plate 11. The limiting member 306 moves toward the transverse mold plate 11. The clamping plate 311 inside the precast composite slab moves, causing the second pin 303 to be inserted between the two clamping plates 311 and engaged with them. After the precast composite slab hardens, the output shaft of the motor 201 is manually controlled to rotate in the opposite direction. The motor 201 drives the clamping plate 311 to move away from the transverse mold plate 11 or the longitudinal mold plate 12. Since the first pin 301 and the second pin 303 are engaged with the clamping plate 311 respectively, the movement of the clamping plate 311 causes the transverse mold plate 11 and the longitudinal mold plate 12 to open, so that the transverse mold plate 11 and the longitudinal mold plate 12 are separated from the precast composite slab, which facilitates the demolding of the precast composite slab. This design enables automatic demolding during the production of precast composite slabs, solves the problem that the transverse mold plate 11 and the longitudinal mold plate 12 have a single stress point and are not easy to disassemble and demold, saves manpower, and improves the production efficiency of precast composite slabs.

[0046] The cam 312 can be manually rotated to support the two clamping plates 311 respectively, so that the two clamping plates 311 can be opened to facilitate the first pin 301 or the second pin 303 to disengage from between the two clamping plates 311. After the first pin 301 or the second pin 303 is disengaged, the extension force of the support spring 310 will reset the clamping plates 311. This design facilitates the disassembly and reassembly of the transverse mold plate 11 and the longitudinal mold plate 12, further improving the ease of use of the device.
