Description

Technical Field

[0001] This invention belongs to the field of engineering construction technology, and in particular relates to a leak-proof fastening device for aluminum formwork tie rods. Background Technology

[0002] Aluminum formwork tie rods are key components in aluminum alloy formwork systems used to connect and fix formwork on both sides, preventing formwork bulging and bursting during concrete pouring, and simultaneously solving the leakage problem caused by through-wall holes in traditional bolt systems. Compared with traditional bolt systems, it eliminates the need for holes in the formwork panel and leaves no holes after demolding, fundamentally reducing the risk of external wall leakage. It also improves the overall rigidity and stability of the wall, breaking away from the traditional wooden formwork and aluminum formwork tie bolt process. A tie rod-type formwork support system is designed using detailed aluminum alloy formwork construction drawings, employing disposable tie rods as the fastening system to improve the flatness of the shear wall surface. Furthermore, the absence of holes in the external wall surface enhances waterproofing.

[0003] Although tie rods are core fastening components of the aluminum formwork system, their inherent thickness can still create gaps when adjacent aluminum formwork panels are joined, disrupting the seal continuity between the panels and weakening the overall leak-proof performance of the aluminum formwork. Furthermore, the traditional method of using wedges with locking rods requires manual hammering of each wedge for tightening, which is not only inefficient and labor-intensive but also difficult to control consistently, directly affecting the accuracy and fit of adjacent formwork panels. During concrete pouring, lateral pressure and vibration impact act on the formwork connections, and uneven locking forces can easily cause loosening and displacement of the aluminum formwork joints, severely impacting the overall stability of the aluminum formwork installation. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a leak-proof fastening device for aluminum mold tie plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an aluminum mold anti-leakage fastening device for tie rods, comprising two adjacent templates, each template having a U-shaped structure, the sidewalls of the templates having multiple locking holes, and locking rods inserted into the corresponding locking holes, one end of each locking rod being fixedly connected to a fixing support plate, and the sidewall of the locking rod away from the fixing support plate having an L-shaped hook groove, further comprising:

[0006] The tensioning power assembly is mounted against the side wall of the template and connected to the locking rod; An elastic contact sealing assembly is installed on the side wall of the template to form the first layer of sealing protection; An active sealing assembly is installed on the side wall of the template and forms a second layer of sealing protection by expanding through water supply.

[0007] In the aforementioned aluminum mold anti-leakage fastening device for tie plates, the tensioning power assembly includes multiple U-shaped positioning plates arranged side by side. One end of each U-shaped positioning plate is fixedly connected to a support plate, which abuts against the side wall of the mold. An adjusting screw is rotatably connected inside the U-shaped positioning plate. The same push-pull plate is threaded onto multiple adjusting screws. Multiple U-shaped hooks corresponding to the positions of the locking rods are movably inserted into the side wall of the push-pull plate. The U-shaped hooks are engaged in the hook grooves. An anti-detachment plate is fixedly connected to the end of the U-shaped hook away from the locking rod. Multiple pressure sensors located on one side of the anti-detachment plate are fixedly installed on the side wall of the push-pull plate.

[0008] In the above-mentioned aluminum mold pull tab anti-leakage fastening device, the elastic contact sealing assembly includes multiple elastic sealing strips fixedly connected to one side of the template. The side wall of the template is also provided with a sealing groove that matches and inserts into the elastic sealing strip. The side wall of the template is also fixedly connected with a wrapping sealing strip. The side wall of the wrapping sealing strip is provided with multiple embedding grooves. The multiple elastic sealing strips and wrapping sealing strips are arranged alternately.

[0009] In the aforementioned aluminum mold tie plate anti-leakage fastening device, the active sealing component includes a water storage cavity opened on the inner side of the end of the template, a plurality of water passage holes communicating with the water storage cavity opened on the side wall of the template, a water supply pipe communicating with the water storage cavity embedded inside the template, the end of the water supply pipe away from the water storage cavity extending through the template and fixedly connected to a water storage tank, a water supply pump installed on the water supply pipe, and a water-swellable waterstop strip detachably and fixedly connected to the side wall of the template, which is corresponding to the positions of the plurality of water passage holes.

[0010] In the above-mentioned aluminum mold tie plate anti-leakage fastening device, a connecting cylinder is fixedly connected to the end of the U-shaped positioning plate away from the supporting plate, and the ends of multiple connecting cylinders away from the U-shaped positioning plate are fixedly connected to the same power housing. One end of the adjusting screw extends through into the power housing and is fixedly connected to a worm gear. A worm is rotatably connected inside the power housing, and the worm and multiple worm gears mesh and drive each other. A servo motor for driving the worm to rotate is also fixedly installed on the inner wall of the power housing.

[0011] In the above-mentioned aluminum mold tie plate anti-leakage fastening device, a temperature sensor is also fixedly installed on the side wall of the mold plate to monitor the ambient temperature and cooperate with the PLC controller to control the working frequency of the water supply pump.

[0012] In the aforementioned aluminum mold tie plate anti-leakage fastening device, the servo motor is a self-locking motor. When the servo motor stops driving the worm gear to rotate, the worm gear remains in a limited locking state.

[0013] In the above-mentioned aluminum mold pull tab anti-leakage fastening device, the side wall of the push-pull plate is fixedly connected to a limit slider, and the inner side of the U-shaped positioning plate is provided with a limit groove that matches and slides with the limit slider.

[0014] Compared with existing technologies, the advantages of this invention are as follows: 1. The set template, locking hole, locking rod, fixed support plate, hook groove and tensioning power component can make two adjacent aluminum templates form a fast docking tension, making the installation efficiency of aluminum templates higher.

[0015] 2. Through the setting of elastic contact sealing components and active sealing components, multiple anti-leakage protections can be formed between two adjacent aluminum formworks, effectively improving the anti-leakage performance of aluminum formwork installation.

[0016] 3. Through the active sealing components and temperature sensors, the frequency of water supply to the water-swellable sealing strip can be automatically adjusted based on the impact of ambient temperature changes on the water-swellable sealing strip, ensuring that the water-swellable sealing strip has sufficient expansion to ensure the connection and sealing between two adjacent aluminum templates.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] like Figures 1-6 As shown, an aluminum mold tie rod anti-leakage fastening device includes two adjacent templates 1, each template 1 having a U-shaped structure. Multiple locking holes 2 are provided on the sidewalls of the templates 1, and locking rods 3 are inserted into the corresponding locking holes 2. One end of the locking rod 3 is fixedly connected to a fixing support plate 4, and the sidewall of the locking rod 3 away from the fixing support plate 4 has an L-shaped groove 5. The device also includes: The tensioning power assembly 6 is installed against the side wall of the template 1 and connected to the locking rod 3; The elastic contact sealing component 7 is installed on the side wall of the template 1 to form the first layer of sealing protection; The active sealing component 8 is installed on the side wall of the template 1 and forms a second sealing protection by expanding through water supply.

[0021] The tensioning power assembly 6 includes multiple U-shaped positioning plates 61 arranged side by side. One end of each U-shaped positioning plate 61 is fixedly connected to a support plate 62, which abuts against the side wall of the template 1. An adjusting screw 63 is rotatably connected inside each U-shaped positioning plate 61. Multiple adjusting screws 63 are threaded onto the same push-pull plate 64. The side wall of the push-pull plate 64 is movably fitted with multiple U-shaped hooks 65, corresponding to the positions of the locking rod 3. The U-shaped hooks 65 are engaged in the hook grooves 5. The end of each U-shaped hook 65 away from the locking rod 3 is fixedly connected to an anti-detachment plate 66. The side wall of the push-pull plate 64 is fixedly... The device is equipped with multiple pressure sensors 67 located on one side of the anti-detachment plate 66. A connecting cylinder 68 is fixedly connected to the end of the U-shaped positioning plate 61 away from the support plate 62. The ends of the multiple connecting cylinders 68 away from the U-shaped positioning plate 61 are fixedly connected to the same power housing 69. One end of the adjusting screw 63 extends through into the power housing 69 and is fixedly connected to a worm gear 610. A worm 611 is rotatably connected inside the power housing 69. The worm 611 and multiple worm gears 610 mesh and drive each other. A servo motor 612 for driving the worm 611 to rotate is also fixedly installed on the inner wall of the power housing 69.

[0022] By adopting the above technical solution, the U-shaped hook rod 65 is hooked into the hook groove 5 on the side wall of the locking rod 3, realizing the relative connection between the push-pull plate 64 and the locking rod 3. Then, the servo motor 612 provides output power to drive the worm gear 611 to rotate. The meshing action of the worm gear 611 and the worm wheel 610 synchronously drives the multiple adjusting screws 63 to rotate. Then, the threaded connection between the adjusting screws 63 and the push-pull plate 64 drives the push-pull plate 64 to move the multiple U-shaped hook rods 65, thereby providing a pulling force to the locking rod 3, so that the two adjacent templates 1 are more closely contacted and fitted together, improving the installation stability.

[0023] The elastic contact sealing assembly 7 includes multiple elastic sealing strips 71 fixedly connected to one side of the template 1. The side wall of the template 1 is also provided with a sealing groove 72 that matches and inserts into the elastic sealing strips 71. The side wall of the template 1 is also fixedly connected with a wrapping sealing strip 73. The side wall of the wrapping sealing strip 73 is provided with multiple inserting grooves 74. The multiple elastic sealing strips 71 and wrapping sealing strips 73 are arranged alternately.

[0024] By adopting the above technical solution, multiple elastic seals can be formed between two adjacent templates 1, effectively increasing the anti-leakage path and ensuring that the gaps between two adjacent templates 1 are not too large due to the protruding thickness of the tie plate, thus affecting the anti-leakage sealing performance. The active sealing assembly 8 includes a water storage chamber 81 opened on the inner side of the end of the template 1, a plurality of water passage holes 82 opened on the side wall of the template 1 communicating with the water storage chamber 81, a water supply pipe 83 communicating with the water storage chamber 81 embedded inside the template 1, the end of the water supply pipe 83 away from the water storage chamber 81 extending through the template 1 and fixedly connected to a water storage tank 84, a water supply pump 85 installed on the water supply pipe 83, and a water-swellable waterstop strip 86 detachably and fixedly connected to the side wall of the template 1, which is corresponding to the positions of the plurality of water passage holes 82.

[0025] By adopting the above technical solution, active sealing and seepage prevention protection can be provided between two adjacent templates 1, and it can be used continuously. This further ensures the sealing stability between the two adjacent templates 1, and the sealing strength can be adjusted according to the actual concrete pouring situation to increase the sealing pressure and ensure that there is enough sealing force to block the leakage of concrete, making the sealing and seepage prevention performance more effective.

[0026] A temperature sensor 9 is also fixedly installed on the side wall of template 1 to monitor the ambient temperature and cooperate with the PLC controller to control the operating frequency of the water supply pump 85.

[0027] By adopting the above technical solution, the water supply frequency of the water-swellable sealing strip 86 in the active sealing component 8 can be automatically and strongly controlled based on changes in ambient temperature, ensuring that the water-swellable sealing strip 86 has sufficient expansion and deformation to guarantee the sealing performance between two adjacent templates 1.

[0028] The servo motor 612 is a self-locking motor. When the servo motor 612 stops driving the worm gear 611 to rotate, the worm gear 611 remains in a limit-locked state.

[0029] By adopting the above technical solution, the worm gear 611 can drive the worm wheel 610 to rotate into position and maintain a stable limit state, thus ensuring the stability of the installation between two adjacent templates 1.

[0030] The side wall of the push-pull plate 64 is fixedly connected to a limit slider, and the inner side of the U-shaped positioning plate 61 is provided with a limit groove that matches and slides with the limit slider.

[0031] The operating principle of the present invention is described as follows: Two templates 1 to be installed are placed together in contact, and multiple locking rods 3 are inserted into the locking holes 2 opened on the side wall of the template 1. At this time, the fixed support plate 4 connected to one end of the locking rod 3 abuts against the side wall of the template 1, while the hook groove 5 opened at the other end of the locking rod 3 passes through the template 1 and is located on the outside of the template 1. The multiple U-shaped hooks 65 on the tensioning power assembly 6 are manually hooked into the hook groove 5 at one end of the locking rod 3 to realize the relative connection between the tensioning power assembly 6 and the multiple locking rods 3. Next, the multiple support plates 62 within the tensioning power assembly 6 are placed against the side wall of the template 1, supplying power to the servo motor 612. The servo motor 612 is powered on and starts, driving the worm gear 611 to rotate. Through the meshing transmission of the worm gear 611 and multiple worm wheels 610, multiple adjusting screws 63 are driven to rotate synchronously. Then, through the threaded connection between the adjusting screws 63 and the push-pull plate 64, the push-pull plate 64 drives multiple U-shaped hooks 65 to move. In turn, through the connection between the U-shaped hooks 65 and the locking rod 3, a pulling force is provided to the locking rod 3. The fixed support plate 4 and the support plate 62 limit the sides of the two templates 1, making the two templates 1 more tightly against each other. The pulling force provided by the U-shaped hooks 65 to the locking rod 3 is transmitted to the pressure sensor 67 through the anti-detachment plate 66. The system judges the pressure by the pressure sensor 67. When the pressure sensor 67 reaches the set threshold, the PLC controller controls the servo motor 612 to stop and put the servo motor 612 into a self-locking state to maintain the strength of the two aluminum plates. It can automatically adjust the assembly strength between two adjacent templates 1 according to the volume of concrete pouring. Compared with the manual assembly method, it is more precise and efficient, ensuring the assembly quality of template 1. When more than 80% of the pressure sensors 67 report that the pressure has reached the threshold, if the pressure value of the pressure sensor 67 is abnormal, a feedback signal is sent to the PLC controller, which triggers an alarm operation for the staff, reminding the staff that there is a problem with the installation of the locking rod 3, and reminding the staff to check it in time to avoid affecting the installation quality of template 1. When two adjacent templates 1 are assembled, the corresponding insertion of the elastic sealing strip and the sealing groove 72 can form multiple bent seepage prevention channels between the two adjacent templates 1. The elastic sealing strip shell forms an abutment against the outside of the tie plate, sealing one side of the tie plate, which effectively improves the sealing protection performance of the template 1 installation. Then, the wrapping sealing strip 73 and the embedding groove 74 seal and wrap the tie plate from both sides, further improving the sealing performance of the adjacent templates 1 installation. When the templates 1 are squeezed during the butt joint installation, the elastic sealing strip 71 and the wrapping sealing strip 73 will undergo compression deformation, which improves the sealing protection strength of the leakage channel and effectively fills the gap between the two adjacent templates 1 caused by the presence of the tie plate. After the two adjacent templates 1 are installed together, the water pump 85, together with the water supply pipe 83, draws water from the water storage tank 84 and delivers it to the water storage chamber 81. Then, it is discharged through multiple water holes 82 connected to the side wall of the water storage chamber 81 to the water-swellable sealing strip 86. The water-swellable sealing strip 86 is a flexible waterproof material made of bentonite or superabsorbent resin as the core expansion material and composite rubber, plastic and other elastic substrates. When the water-swellable sealing strip 86 comes into contact with water, the bentonite or superabsorbent resin inside will quickly absorb the water and trigger a volume expansion reaction. After absorbing water, the volume of the water-swellable sealing strip 86 increases significantly and will be squeezed to the surroundings to completely fill the gap between the two adjacent templates 1, eliminate the physical space for water seepage, and can cover the tie plate to provide effective sealing and seepage prevention protection. Temperature sensor 9 monitors the ambient temperature in real time. When the ambient temperature is high, it indicates that the water evaporation rate inside the water-swellable sealing strip 86 is faster. The PLC controller controls the water supply pump 85 to work at a higher interval frequency to ensure that there is sufficient water inside the water-swellable sealing strip 86 to support the expansion effect. Because the expansion process of the water-swellable sealing strip 86 is reversible, if the water evaporates, the water-swellable sealing strip 86 will shrink and can expand again when it encounters water again. Therefore, when the temperature is high and the water evaporates quickly, the water supply frequency to the water-swellable sealing strip 86 is increased to ensure that the expansion performance of the water-swellable sealing strip 86 can play an effective role in sealing and preventing leakage. Moreover, when the tensioning power component 6 provides a greater tensile connection force, the water supply to the water-swellable sealing strip 86 is set to be larger, so that the water-swellable sealing strip 86 has sufficient expansion effect to ensure the leakage prevention and sealing strength, and self-matching for leakage prevention protection.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
