Description

Technical Field

[0002] Formwork supports the self-weight of concrete and the lateral pressure during the pouring process, ensuring accurate pouring and curing of concrete. Formwork can also withstand the loads of personnel, equipment and materials, ensuring the stability and safety of the construction project. Formwork can shape and control the geometry of the concrete structure according to design requirements, ensuring that it meets design requirements and specifications. The fabrication and installation of formwork requires precise measurement and adjustment to ensure the verticality, horizontality and dimensional accuracy of the concrete structure.

[0003] Chinese patent CN110394883A proposes a formwork structure for precast concrete slabs, including a support frame; a mold placed on top of the support frame, with movable plates erected on both sides of the mold, the mold and the movable plates enclosing a pouring space for the precast concrete slab; and two adjustment mechanisms located at both ends of the support frame, each adjustment mechanism including a pair of opposing support rods and an adjustment component for pushing the pair of support rods closer together, thereby adjusting the distance between the movable plates. This invention designs one side of the mold as a movable plate, and uses adjustment mechanisms to support and adjust the movable plates, thereby adjusting the distance between the movable plates. This allows for adjusting the width of the pouring space and reinforcing the mold during concrete slab pouring, as well as reinforcing the concrete slab after pouring. However, this solution is inconvenient for demolding the concrete slab, requiring a significant amount of time.

The first electromagnetic coil 7 and the second electromagnetic coil 8 have opposite magnetic poles and attract each other, fixing the pressing plate 6 in place. Concrete is poured into the formwork body 4. When the concrete solidifies, the electric telescopic rod 121 is activated. The electric telescopic rod 121 drives the limiting plate 122 for adjustment, and the limiting plate 122 drives the locking block 123. Adjustment is performed by removing the locking block 123 from the slot 124 to reinforce the formwork body 4. The electric track 111 is then activated, causing the track block 112 to adjust. The track block 112 then adjusts the L-shaped fixing plate 113, which in turn adjusts the connecting block 114. The connecting block 114 then adjusts the sealing plate 115, moving it out of the formwork body 4. Finally, the second motor 102 is activated, driving the small pulley 103 to rotate. The small pulley 103 is connected by a belt... The large pulley 104 is driven to rotate, which in turn drives the connecting shaft 105 to rotate, which in turn drives the formwork body 4 to rotate, unloading the double-cantilevered concrete slabs from the surface of the formwork body 4. After unloading, the formwork body 4 is reset, and the electric telescopic rod 121 is activated. The electric telescopic rod 121 drives the limiting plate 122 to adjust, which in turn drives the locking block 123 to adjust, adjusting the locking block 123 into the slot 124 to reinforce the connection of the formwork body 4. When height adjustment is required, the first motor 91 is activated, and the second motor 92 is activated. A motor 91 drives a multi-groove pulley 92 to rotate. The multi-groove pulley 92 drives a slave pulley 93 to rotate via a belt. The slave pulleys 93 drive a threaded rod 94 to rotate. The threaded rod 94 rotates inside the threaded groove 96. Adjusting the adjusting block 2 upwards, the formwork body 4 is adjusted to the required height. The threaded pipe 18 is inserted into the threaded hole 17. The threaded pipe 18 is rotated to connect the water pipe 19 to the inlet pipe 15 and the outlet pipe 16, so that hot water is transmitted from the inlet pipe 15 to the inside of the formwork body 4 to solidify the concrete inside the formwork body 4.
