A second mounting plate 16 is welded to one end of the second support beam 15. The second mounting plate 16 is connected to the ground by bolts.

[0018] In this embodiment, the installation platform 1 includes an installation frame 102 welded from several support pipes 101. A steel plate 103 is installed on the surface of the installation frame 102. One end of the first support beam 2 is fitted into the end of the support pipe 101. Several first positioning holes 104 are opened on the side of the support pipe 101. Several second positioning holes 17 are opened on the side of the first support beam 2. The support pipe 101 and the first support beam 2 are fixed together by bolts installed in the aligned first positioning holes 104 and second positioning holes 17.

[0019] Specifically, a steel plate 103 is installed on the surface of the mounting frame 102 formed by welding the support pipe 101, allowing workers to perform formwork construction on the surface of the steel plate 103. The length of the first support beam 2 can be adjusted through the first positioning hole 104 and the second positioning hole 17, extending the first support beam 2 to fit the inner wall of the elevator shaft with the first mounting plate 4. The first mounting plate 4 is then fixed to the inner wall of the elevator shaft with bolts. The first support beam 2 is then fixed by connecting the bolts to the first positioning hole 104 and the second positioning hole 17.

[0022] In this embodiment, the support tube 101, the first support beam 2, the fixed beam 8, and the second support beam 15 are all rectangular tubes.

[0023] Specifically, this method enables the device to significantly reduce the use of scaffolding materials, saving labor for scaffolding erection and construction time required for scaffolding dismantling.

[0024] In this embodiment, the lifting lug 3 is welded to the surface of the steel plate 103.

[0025] Specifically, the lifting lugs 3 allow the device to be lifted as a whole using a tower crane or electric hoist.

[0026] Working principle: The first support beam 2 and the second support beam 15 facilitate the fixing of the device in the elevator shaft. The lengths of the first support beam 2 and the second support beam 15 are adjustable, making them suitable for formwork construction in elevator shafts of different sizes. The installation platform 1 facilitates formwork work on the surface. The lifting lugs 3 allow the device to be lifted as a whole by tower cranes or electric hoists. The components of the device are fixed with bolts, making installation and dismantling convenient. The first angle iron 9, the second angle iron 10, the third angle iron 11, and the fourth angle iron 14 form a triangular structure with the installation platform 1 and the fixing beam 8, which improves the stability of the device during use.
