In the embodiment 1, as shown in fig. 1 to 7, when it is required to install the i-steel 8 and to reinforce and support the end of the i-steel 8 away from the overhanging scaffold 1, the i-steel 8 is firstly placed on the inner sides of two adjacent groups of embedded U-shaped bolts 7, and the fixing plate 19 is covered to tighten the first nut 10, so that the I-shaped steel 8 is fixedly arranged on the ground of the corresponding floor of the shear wall body 11, then the top end of the first steel pull rod 3 is fixed to the outer side of the corresponding group of mounting seats 14, the bottom end of the second steel pull rod 12 is hinged to the top of the I-shaped steel 8, then, the internal threaded tube 902 is rotated by the auxiliary rotating rod 906, the distance between the first threaded rod 901 and the second threaded rod 903 is shortened, and then, the movable seat 904 is tightly fixed on the i-steel 8 through a fixing bolt 905, and the i-steel 8 is supported by a support rod consisting of a first threaded rod 901, an internal threaded pipe 902 and a second threaded rod 903.

Example 2, as shown in fig. 1 to 7, after the overhanging scaffold 1 is fixedly installed on the top of the i-beam 8, the auxiliary pipe 2 is fixed on the corresponding steel pipe of the overhanging scaffold 1 through a rotating fastener, one end of the auxiliary pipe 2 close to the shear wall body 11 penetrates through a fixing hole 16 on the embedded plate 15, then the auxiliary pipe 2 is fixedly connected with the embedded plate 15 through a second nut 13, the stability of the steel pipe at each height position of the cantilever scaffold 1 can be ensured by utilizing the auxiliary pipe 2 and the embedded plate 15, when the height of the overhanging scaffold 1 is gradually increased, the pressure applied to one end of the top of the I-steel 8 close to the overhanging scaffold 1 is also gradually increased, and because the first steel pull rod 3, the turn buckle 4, the I-shaped steel 8, the reinforcing component 9 and the second steel pull rod 12 jointly form a stable triangular structure, the stress capacity of the I-shaped steel 8 can be further improved.

The working principle is as follows: before installing the I-steel 8, pre-embedded U-shaped bolts 7, pre-embedded plates 15 and pre-embedded steel pipes are uniformly pre-embedded in the wall body of the shear wall body 11 in advance, the positions are shown in the attached drawing 1 of the specification, then the installation seats 14 are fixedly installed on the inner wall and the outer wall of the shear wall body 11 through high-strength bolts, then the I-steel 8 is placed on the inner sides of two adjacent groups of pre-embedded U-shaped bolts 7, the first nuts 10 are tightly screwed on the fixing plates 19, so that the I-steel 8 is fixedly installed on the ground of the corresponding floor of the shear wall body 11, then the top ends of the first steel pull rods 3 are fixed to the outer sides of the corresponding group of installation seats 14, the bottom ends of the second steel pull rods 12 are hinged to the top of the I-steel 8, then the auxiliary rotating rods 906 are used for rotating the internal threaded pipes 902 to shorten the distance between the first threaded rods 901 and the second threaded rods 903, and then the movable seats 904 are tightly fixed on the I-steel 8 through the fixing bolts 905, the I-steel 8 is supported by a support rod consisting of a first threaded rod 901, an internal threaded pipe 902 and a second threaded rod 903, then steel pipes on the overhanging scaffold 1 are installed on the top of the I-steel 8 one by one, the complete overhanging scaffold 1 is assembled, in the process, an auxiliary pipe 2 is fixed on the corresponding steel pipe on the overhanging scaffold 1 through a rotary fastener, one end, close to a shear wall 11, of the auxiliary pipe 2 penetrates through a fixing hole 16 on an embedded plate 15, then the auxiliary pipe 2 is fixedly connected with the embedded plate 15 through a second nut 13, so that the stable installation of the pull-up overhanging scaffold is completed, when the height of the overhanging scaffold 1 is gradually increased, the pressure applied to one end, close to the overhanging scaffold 1, of the top of the I-steel 8 is gradually increased, and a stable triangular structure is formed by the first steel tie rod 3, the turn buckle 4, the I-steel 8, the reinforcing component 9 and the second steel tie rod 12 together, the force-bearing capacity of the i-beam 8 can be further improved.
