Example (b): as shown in fig. 1 to 4, the construction protection platform for quick mounting and dismounting of precast beam tensioning equipment in this embodiment includes rear portal 1, middle portal 2 and socket front leg 3, and longitudinal beam 4 is disposed at the top of the three and is fixed by connection so as to form an integral structure through rear portal 1, middle portal 2 and socket front leg 3. The lower part position between back portal 1 and well portal 2 is provided with place the platform 5, and this place the platform has not only improved the joint strength and the wholeness between back portal 1 and the well portal 2, still can supply the required operation device of stretch-draw operations such as stretch-draw machines and spare part to place. In order to further increase the strength of the support frame, a diagonal bar support 6 is also provided between the middle door frame 2 and the longitudinal beam 4.
As shown in fig. 1 to 4, two longitudinal rails 8 are arranged on the longitudinal beam 4 between the top of the middle portal 2 and the top of the socket type front supporting leg 3, and each longitudinal rail 8 is provided with a longitudinal roller device 7. A transverse rail 10 is hoisted below the two longitudinal roller devices 7, and the transverse rail 10 is vertically arranged with the longitudinal rail 8. A transverse roller device 9 is arranged on the transverse rail 10, and a jack hoisting device 11 is arranged below the transverse roller device 9. U-shaped anti-falling clamps 12 are arranged on two sides of the longitudinal rail 8 and the transverse rail 10 respectively and used for limiting the moving stroke of the longitudinal roller device 7 and the transverse roller device 9 and avoiding accidents caused by stroke overrun. In this way, the jack hoisting device 11 can be moved laterally within the range of the lateral rail 10 by means of the lateral roller device 9, and can also be moved longitudinally within the range of the longitudinal rail 8 by means of the longitudinal roller device 7, so that the position of the jack for tensioning operation can correspond to the steel strands at different positions.
Referring to fig. 1 and 4, the socket type front support leg 3 is erected on the precast beam 15 to ensure the stability of the whole construction protection platform. In order to make the length of the socket front leg 3 adjustable, i.e. the socket front leg 3 can be adapted to box girders of different sizes. The socket type front supporting leg 3 is provided with a plurality of jacks, the corresponding positions of the longitudinal beam 4 can be provided with jacks, the socket type front supporting leg 3 and the longitudinal beam 4 can be connected and fixed through inserting the inserted pin 13 after the jacks are aligned, and meanwhile, the length of the socket type front supporting leg 3 can be adjusted through switching of the jacks at different positions on the socket type front supporting leg 3, and the socket type front supporting leg can be supported on the precast beam 15.
