[0022] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, this embodiment provides a simple device for wet joint formwork installation, including formwork 1. A bolts for fixing a plurality of main battens 2 are threadedly penetrated through the lower surface of formwork 1. B bolts for fixing a plurality of secondary battens 3 are threadedly penetrated through the lower surface of the plurality of main battens 2. A plurality of holes are provided on the lower surface of the plurality of secondary battens 3, and a tie rod 4 is penetrated through the inside of the holes. The formwork 1 is a composite plywood formwork with a thickness of 2 cm, a length of 189 cm, and a width of 93.1 cm. Through the main battens 2 and the secondary battens 3, the support for the formwork 1 is more comprehensive, reducing the uneven force on the formwork 1 during concrete pouring, resulting in tilting and bending, and improving the service life of the formwork 1.

[0023] Hexagonal nuts 5 are threadedly connected to both ends of the tie rod 4. A top rod 6 is inserted into the top end of the tie rod 4. The secondary battens 3 are supported by the tie rod 4 to ensure that the formwork 1 is uniformly stressed and stably supported during concrete pouring.

[0024] Supports 7 are fixedly connected to both ends of the top rod 6, and steel bars 8 are welded between the top rods 6.

[0025] An anti-tilting rod 9 is fixedly connected to the middle of the top rod 6. A steel wire rope 10 is penetrated through the middle of the anti-tilting rod 9. The steel wire rope 10 is a steel wire with a diameter of 8 mm. The formwork 1 is lifted by inserting the steel wire rope 10 into the anti-tilting rod 9, so that the position of the formwork 1 is below the top rod 6, facilitating the installation of the tie rod 4.

[0026] A traction steel bar 11 is wound around the bottom end of the steel wire rope 10. Both ends of the traction steel bar 11 are fixedly connected to the middle of the lower surface of the two main battens 2. A lifting hole 12 is provided at the middle of the formwork 1 and one of the main battens 2. The bottom end of the steel wire rope 10 is inserted into the inside of the lifting hole 12.

[0027] Both ends of multiple secondary battens 3 are fixedly connected with connecting rings 13. A towing rope 14 is wound around the surface of the connecting ring 13. The towing rope 14 is a nylon rope with a diameter of 2.5 cm. After the concrete is poured, after the reinforcement bars of the next wet joint are installed, the towing rope 14 can be hooked to the position of another wet joint by using a hook, so that there is no need for personnel to hoist the formwork 1 again, greatly improving the transfer efficiency of the formwork 1 between wet joints.

[0028] Specifically, when this simple device for wet joint formwork installation is in operation / use: When in use, the steel wire pull rope 10 is inserted into the anti-tilting rod 9 and the steel wire pull rope 10 is pulled upward to lift and install the formwork 1 upward, making it easier for the formwork 1 to align with the ejector rod 6. After alignment, the hexagon nut 5 at the top of the tension rod 4 is removed and inserted into the ejector rod 6 to fix the formwork 1. After the concrete is poured, after the reinforcement bars of the next wet joint are installed, the towing rope 14 is hooked to the position of another wet joint by using a hook and fixed by using the ejector rod 6. This process is repeated, greatly reducing the time consumed by personnel repeatedly hoisting the formwork 1 through mechanical equipment, and at the same time avoiding the safety hazards caused by the formwork 1 falling during demolition. The device has a simple structure, small size, light weight, low manufacturing cost, fast construction progress, high installation efficiency and high safety performance.
