[0024] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0025] See Figure 1 and Figure 2 This utility model discloses a large template hoisting tool, which includes two L-shaped fixing frames 1, several bolt-type connecting rods 2, and a sliding disassembly base 3 set at the bottom of the L-shaped fixing frame 1. The L-shaped fixing frame 1 includes a vertically arranged side plate 11, a vertically arranged base plate 12 and fixed perpendicularly to the side plate 11, and a connecting plate 13 vertically arranged and fixed to the end of the base plate 12 away from the side plate 11.

[0026] The connecting plate 13 has several mounting holes 131. There are 8 mounting holes 131, arranged in four rows of two. The vertical spacing between two adjacent rows of mounting holes 131 is 500mm, and the horizontal spacing between two adjacent rows of mounting holes 131 is 200mm.

[0027] Two L-shaped fixing frames 1 are arranged opposite each other, and two connecting plates 13 are pressed together. The two L-shaped fixing frames 1 are fixed by inserting bolts into the mounting holes 131 to form a U-shaped fixing frame. In this embodiment, the width of the base plate 12 of the L-shaped fixing frame 1 can be made into any size according to the needs of the site, so as to realize the function of hoisting large templates of different widths.

[0028] A lifting hole 111 is provided at the top of the side plate 11 for easy hoisting of large formwork, improving construction efficiency and safety. Several through holes 112 are provided from top to bottom on the side of the side plate 11 away from the base plate 12 for inserting bolt-type connecting rods 2. The length of the bolt-type connecting rod 2 is 10cm longer than the width of the U-shaped fixing frame. Threads with a diameter of 60mm are provided on one side of the bolt-type connecting rod 2. In this embodiment, the diameter of the through holes 112 is 65mm to facilitate the insertion and extension of the bolt-type connecting rod 2.

[0029] An M60 nut is fixed to the outer surface of the side plate 11 on the outer side of each through hole 112 of one of the L-shaped fixing frames 1 to match the threads at both ends of the bolt-type connecting rod 2. The bolt-type connecting rod 2 is inserted into the through hole 112 of the L-shaped fixing frame 1 without an M60 nut, and passes through the through hole 112 of the L-shaped fixing frame 1 with an M60 nut, and is screwed to the M60 nut.

A handle 31 is provided on one side of the sliding disassembly base 3 to facilitate on-site personnel in pulling out and pushing the sliding disassembly base 3 into the groove 113.

[0031] When using this utility model's large formwork hoisting tool on site, firstly, two L-shaped fixing frames 1 are fixedly connected to form a U-shaped fixing frame. Then, the U-shaped fixing frame is laid flat with the opening facing upwards, and the sliding disassembly base 3 is pushed into the sliding groove 113 and secured. Next, the large formwork to be hoisted is placed into the U-shaped fixing frame. After the large formwork is placed, several bolt-type connecting rods 2 are inserted into the side plate 11 without M60 nuts and exited from the side plate 11 with M60 nuts, and simultaneously screwed and fixed with the M60 nuts. Then, the hoisting rope, hoisting steel, or hook on the hoisting machinery is passed through the hoisting hole 111, and the entire U-shaped fixing frame connected to the large formwork is hoisted using the hoisting machinery. During the hoisting process, the on-site personnel check the condition of the tools. After the large formwork is hoisted to the required position, the sliding disassembly base 3 is manually pulled out, the large formwork is removed, and the hoisting machinery then lifts the hoisting tool away.

[0032] The large formwork hoisting tool of this invention can save 1 / 4 of the hoisting time, greatly improve construction efficiency, and shorten the construction period. Moreover, the formwork installation using this hoisting tool is convenient and quick, and the hoisting is stable and reliable, ensuring the quality of construction and installation.
