[0027] Such as Figures 1 to 6As shown in the figure, a group of formworks for precast beams of concrete modular buildings includes a chassis 1 and multiple groups of unit modules 3. A running track 2 is arranged on the surface of the chassis 1. Walking wheels 31 are arranged at both the front and rear ends of the unit module 3. The unit module 3 in the middlemost part is fixedly installed with the chassis 1, and the unit modules 3 on both sides are slidably arranged on the running track 2 on the surface of the chassis 1 through the walking wheels 31. Tie rod locking mechanisms 4 are arranged on the top surfaces and the ground surfaces of the unit module 3 in the middlemost part and the unit modules 3 on both sides. Two groups of high-frequency attached vibrators 5 are respectively arranged on the surfaces of the unit modules 3 on both sides. More specifically, during the on-site operation process, first, the unit modules 3 are opened separately, release agent is applied to both sides of the unit module 3, a steel mesh is installed, the thickness of the steel bar protective layer is adjusted using a flywheel or a bracket, and the embedded parts are assembled and fixed by magnetic adsorption. After checking and confirming that the dimensions are correct, the unit module 3 is closed. The tie rod locking mechanisms 4 at the top and bottom of the unit module 3 are used to lock between multiple groups of unit modules 3 to achieve closing of the formwork. The high-frequency attached vibrators 5 are used for vibrating, optimizing the complex finishing process, reducing the occupied site space area, greatly improving the surface flatness and accuracy of the components. After the components are formed, there is no need for traditional flipping work. The construction is simple, the operation is convenient, the performance is reliable, the labor intensity is reduced, the labor is saved, and the production efficiency is greatly improved.
[0028] A wall-piercing rod 6 is arranged on the surface of the unit module 3 in the middlemost part, and the unit modules 3 on both sides are movably inserted with the wall-piercing rod 6. More specifically, through the wall-piercing rod 6, when pouring the precast beam of the concrete modular building, a wall-piercing hole is formed in the middle part.
[0029] On the top surfaces of multiple groups of unit modules 3 except the unit module 3 in the middlemost part, flow guiding plates 7 are fixedly installed, and the flow guiding plates 7 are inclined. More specifically, by arranging the flow guiding plates 7 on the top surfaces of the unit modules 3, it is convenient for the concrete to fall quickly, preventing the concrete from falling onto the top of the unit module 3 and causing damage to the formwork.
[0030] The tie rod locking mechanism 4 includes a mounting base 401. The mounting base 401 is fixedly installed on the top surface of the middlemost unit module 3. A rotating shaft 402 is rotatably inserted on the surface of the mounting base 401, and a threaded rod 403 is fixedly installed on the surface of the rotating shaft 402. The threaded rod 403 is arranged to be flipped with the mounting base 401 through the rotating shaft 402. Locking seats 404 are fixedly installed on the top surfaces of the unit modules 3 on both sides, and a U-shaped opening 405 is formed on the top surface of the locking seat 404. More specifically, by removing the threaded knob sleeved on the thread of the threaded rod 403 and lifting the threaded rod 403 so that the threaded rod 403 disengages from the U-shaped opening 405 on the top surface of the locking seat 404, the fixation of the unit modules 3 on both sides is released. By fitting the unit modules 3 on both sides together, the threaded rod 403 is flipped so that the threaded rod 403 is inserted into the U-shaped opening 405 on the top surface of the locking seat 404. By sleeving the threaded knob onto the surface of the threaded rod 403, the unit module 3 is fixed, and the mold closing operation is completed.
[0031] An L-shaped bottom drag 8 is fixedly installed on the bottom surface of the unit module 3, and a foamed rubber sponge strip 81 is arranged at the end face of the L-shaped bottom drag 8. More specifically, the L-shaped bottom drag 8 on the bottom surface of the unit module 3 is used to support the hoisted steel mesh. The foamed rubber sponge strip 81 pasted on the end face of the L-shaped bottom drag 8 can prevent slurry leakage during pouring after the mold is closed.
[0032] One side of the unit module 3 is a rough surface of a checkered plate, and the other side is a smooth surface. More specifically, by having the two sides of the unit module 3 be the rough surface of the checkered plate and the smooth surface respectively, the flatness of the surface of the precast beam of the concrete modular building can be ensured after one-time pouring and molding.
[0033] In summary: During the on-site operation process, first, the unit modules 3 are opened separately, release agent oil is applied to both sides of the unit modules 3, steel mesh is installed, a flywheel or a bracket is used to adjust the thickness of the steel bar protective layer, the embedded parts are assembled and fixed by magnetic adsorption. After checking that the dimensions are correct, the unit modules 3 are closed. The tie rod locking mechanism 4 at the top and bottom of the unit module 3 is used to lock between multiple groups of unit modules 3 to achieve mold closing. A high-frequency attached vibrator 5 is used for vibration. The complex finishing process is optimized, the occupied site space area is reduced, the flatness and precision of the component surface are greatly improved. After the component is formed, there is no need for the traditional flipping process. The construction is simple, the operation is convenient, the performance is reliable, the labor intensity is reduced, the labor is saved, and the production efficiency is greatly improved.
