[0002] With the development of the times and the progress of society, high-rise and super-high-rise buildings have entered an accelerated era. The construction technology of external scaffolding of high-rise buildings has also received more and more attention and research. Cantilever scaffolding is one of the top ten new technologies in the construction industry promoted by the Ministry of Construction. It is increasingly widely used in high-rise building construction because of its low one-time investment (saving a lot of turnover materials), wide range of applications, no restrictions on floor height and site, and conducive to on-site civilized construction management.

[0003] The current method of installing the pull-up cantilever scaffolding is usually to bury U-shaped anchors in the floor slab in advance, and then use the U-shaped anchors to fix the I-beams. Although this installation method can fix the I-beams, when the cantilever scaffolding installed on the I-beams is heavy, the stability requirements of the U-shaped anchors are extremely high, and it is impossible to further improve the stability of the I-beams while reducing the force applied by the I-beams to the U-shaped anchors; and when the current pull-up cantilever scaffolding construction devices are in use, most of them only rely on the steel pull rods to pull the exposed end of the I-beams to increase the bearing capacity of the I-beams, and it is impossible to further improve the stability of the pull-up cantilever scaffolding after installation while increasing the bearing capacity of the I-beams.

[0039] Furthermore, a method for using the pull-up cantilever scaffolding construction device is provided, and the steps of the method for using the pull-up cantilever scaffolding construction device are as follows:

[0040] 1. Pre-embed U-bolts 7, embedded plates 15 and embedded steel pipes evenly in the shear wall 11 in advance. The positions are as shown in the attached manual. Figure 1 As shown, the mounting base 14 is then fixedly mounted on the inner and outer walls of the shear wall 11 by high-strength bolts, and then the I-beam 8 is placed inside the two adjacent sets of embedded U-bolts 7, and the fixing plate 19 is covered and the first nut 10 is tightened, so that the I-beam 8 is fixedly mounted on the ground of the corresponding floor of the shear wall 11;

[0041] Second, the top end of the first steel tie rod 3 is then fixed to the outside of the corresponding set of mounting seats 14, and the bottom end of the second steel tie rod 12 is hinged to the top of the I-beam 8, and then the internal threaded tube 902 is rotated by the auxiliary rotating rod 906 to shorten the distance between the first threaded rod 901 and the second threaded rod 903, and then the movable seat 904 is tightly fixed to the I-beam 8 by the fixing bolts 905, and the I-beam 8 is supported by the support rod composed of the first threaded rod 901, the internal threaded tube 902 and the second threaded rod 903;

[0042] 3. Then, the steel pipes on the cantilever scaffolding 1 are installed one by one on the top of the I-beam 8 to assemble the complete cantilever scaffolding 1. During the process, the auxiliary pipe 2 is fixed to the corresponding steel pipe on the cantilever scaffolding 1 by means of a rotating fastener, and the end of the auxiliary pipe 2 close to the shear wall 11 is passed through the fixing hole 16 on the embedded plate 15. After that, the auxiliary pipe 2 and the embedded plate 15 are fixedly connected by the second nut 13. At this point, the stable installation of the pull-up cantilever scaffolding is completed.

[0043] Embodiment 1, as Figure 1-7 As shown, when it is necessary to install the I-beam 8 and reinforce the end of the I-beam 8 away from the cantilever scaffolding 1, first place the I-beam 8 on the inner side of the two adjacent groups of embedded U-bolts 7, cover the fixing plate 19 and tighten the first nut 10, so that the I-beam 8 is fixedly installed on the ground of the corresponding floor of the shear wall 11, and then the top end of the first steel tie rod 3 is fixed to the outside of the corresponding group of mounting seats 14, and the bottom end of the second steel tie rod 12 is hinged to the top of the I-beam 8, and then the internal threaded tube 902 is rotated by the auxiliary rotating rod 906 to shorten the distance between the first threaded rod 901 and the second threaded rod 903, and then the movable seat 904 is tightly fixed to the I-beam 8 by the fixing bolts 905, and the I-beam 8 is supported by the support rod composed of the first threaded rod 901, the internal threaded tube 902 and the second threaded rod 903.

[0044] Embodiment 2, as Figure 1-7 As shown, after the cantilever scaffolding 1 is fixedly installed on the top of the I-beam 8, the auxiliary pipe 2 is fixed to the corresponding steel pipe on the cantilever scaffolding 1 by a rotating fastener, and the end of the auxiliary pipe 2 close to the shear wall 11 passes through the fixing hole 16 on the embedded plate 15, and then the auxiliary pipe 2 and the embedded plate 15 are fixedly connected by the second nut 13. The auxiliary pipe 2 and the embedded plate 15 can ensure the stability of the steel pipes at various height positions of the cantilever scaffolding 1. When the height of the cantilever scaffolding 1 gradually increases, the pressure on the end of the top of the I-beam 8 close to the cantilever scaffolding 1 also gradually increases. Since the first steel tie rod 3, the basket bolt 4, the I-beam 8, the reinforcement assembly 9 and the second steel tie rod 12 together constitute a stable triangular structure, the force-bearing capacity of the I-beam 8 can be further improved.

[0045] Working principle: Before installing the I-beam 8, pre-embed U-bolts 7, pre-embedded plates 15 and pre-embedded steel pipes are evenly embedded in the shear wall 11 in advance. The positions are as shown in the attached manual. Figure 1As shown, the mounting seat 14 is then fixedly installed on the inner and outer walls of the shear wall 11 by high-strength bolts, and then the I-beam 8 is placed on the inner side of the two adjacent groups of embedded U-bolts 7, and the fixing plate 19 is covered and the first nut 10 is tightened, so that the I-beam 8 is fixedly installed on the ground of the corresponding floor of the shear wall 11, and then the top end of the first steel tie rod 3 is fixed to the outer side of the corresponding group of mounting seats 14, and the bottom end of the second steel tie rod 12 is hinged to the top of the I-beam 8, and then the internal threaded tube 902 is rotated by the auxiliary rotating rod 906 to shorten the distance between the first threaded rod 901 and the second threaded rod 903, and then the movable seat 904 is tightly fixed on the I-beam 8 by the fixing bolts 905, and the support rod composed of the first threaded rod 901, the internal threaded tube 902 and the second threaded rod 903 is used to support the I-beam. 8 is used for support, and then the steel pipes on the cantilever scaffolding 1 are installed one by one to the top of the I-beam 8, and the complete cantilever scaffolding 1 is assembled. During the process, the auxiliary pipe 2 is fixed to the corresponding steel pipe on the cantilever scaffolding 1 by a rotating fastener, and the end of the auxiliary pipe 2 close to the shear wall 11 passes through the fixing hole 16 on the embedded plate 15, and then the auxiliary pipe 2 and the embedded plate 15 are fixedly connected by the second nut 13. At this point, the stable installation of the upper pull-up cantilever scaffolding is completed. When the height of the cantilever scaffolding 1 gradually increases, the pressure on the end of the top of the I-beam 8 close to the cantilever scaffolding 1 also gradually increases. Since the first steel tie rod 3, the basket bolt 4, the I-beam 8, the reinforcement assembly 9 and the second steel tie rod 12 together constitute a stable triangular structure, the force-bearing capacity of the I-beam 8 can be further improved.

Pre-embedded U-shaped bolts (7), pre-embedded plates (15) and pre-embedded steel pipes are uniformly pre-embedded in the wall of the shear wall (11) in advance, and then the mounting base (14) is fixedly installed on the inner wall and the outer wall of the shear wall (11) by high-strength bolts, and then the I-beam (8) is placed on the inner side of two adjacent groups of pre-embedded U-shaped bolts (7), and the fixing plate (19) is covered and the first nut (10) is tightened, so that the I-beam (8) is fixedly installed on the ground of the corresponding floor of the shear wall (11); Second, the top end of the first steel tie rod (3) is then fixed to the outside of a corresponding set of mounting seats (14), and the bottom end of the second steel tie rod (12) is hinged to the top of the I-beam (8), and then the internal threaded tube (902) is rotated by the auxiliary rotating rod (906) to shorten the distance between the first threaded rod (901) and the second threaded rod (903), and then the movable seat (904) is tightly fixed to the I-beam (8) by the fixing bolt (905), and the I-beam (8) is supported by the support rod composed of the first threaded rod (901), the internal threaded tube (902) and the second threaded rod (903); 3. Next, the steel pipes on the cantilever scaffolding (1) are installed one by one on the top of the I-beam (8) to assemble the complete cantilever scaffolding (1). During the process, the auxiliary pipe (2) is fixed to the corresponding steel pipe on the cantilever scaffolding (1) by means of a rotating fastener, and the end of the auxiliary pipe (2) close to the shear wall (11) is passed through the fixing hole (16) on the embedded plate (15). Then, the auxiliary pipe (2) and the embedded plate (15) are fixedly connected by means of a second nut (13). Thus, the stable installation of the pull-up cantilever scaffolding is completed.
