[0002] In the field of construction, cantilever scaffolding is an indispensable temporary support structure in high-rise building construction. Its safety and turnover have always been the focus of attention of engineers. However, the traditional cantilever scaffolding U-shaped anchor ring has significant limitations in use.

[0003] When installing, traditional U-shaped anchor rings usually need to be embedded in the structural plate and fixed as the structural plate is poured. This design allows the scaffolding to be stably cantilevered outside the building during the construction process. However, after the construction is completed, the removal of the cantilevered scaffolding becomes a problem. Since the U-shaped anchor ring is tightly connected to the structural plate, the U-shaped anchor ring often needs to be cut during removal, which not only increases the difficulty of construction, but also the U-shaped anchor ring after cutting loses its value for reuse due to structural damage, resulting in a waste of resources.

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-2 As shown, the utility model provides a cantilever scaffold U-shaped anchor ring that can be used cyclically, including a steel plate 10, two hinge grooves 101 are symmetrically arranged along the center length direction of the top of the steel plate 10, and a U-shaped anchor ring 20 is movably arranged at the hinge groove 101. The steel plate 10 is pre-buried at the bottom of the structural plate 70, and a release agent is applied to the top and surrounding of the steel plate 10. The outer surfaces of both sides of the U-shaped anchor ring 20 are sleeved with sleeve devices 50, and the top of the sleeve device 50 extends to the top of the structural plate 70. The U-shaped anchor ring 20 is isolated from concrete by the sleeve device, and an I-beam is placed on the top of the structural plate 70. 60. The I-beam 60 is located on the inner side of the U-shaped anchor ring 20. A steel pressure plate 30 is arranged on the top of the I-beam 60. Both sides of the steel pressure plate 30 are fixedly arranged on the U-shaped anchor ring 20. When it needs to be dismantled, the steel pressure plate 30 is firstly dismantled, and then the bottom of the structural plate 70 moves the steel plate 10 downward. At this time, both sides of the U-shaped anchor ring 20 are moved out from the inside of the sleeve device. This design solves the problem that the traditional anchor ring cannot retain its integrity during dismantling, and ensures that the U-shaped anchor ring 20 can still remain intact after the scaffolding is dismantled, which is convenient for next use, thereby improving construction efficiency and reducing construction costs.

[0023] In this embodiment, threads are provided on the upper sections of both sides of the U-shaped anchor ring 20, and through holes are provided on the top of the steel pressure plate 30 near the two ends. The U-shaped anchor ring 20 is inserted into the through holes, and the top two sides of the steel pressure plate 30 are tightened and fixed to the U-shaped anchor ring 20 by double nuts 40. The two nuts are fixed to each other to increase the tightening torque, thereby preventing the steel pressure plate 30 from loosening during the concrete pouring and vibration process, and ultimately making it impossible for the steel pressure plate 30 to provide a fixing effect for the I-beam 60.

[0024] In this embodiment, the sleeve device 50 includes a plastic sleeve 51 and a threaded limiting tube 52. The plastic sleeve 51 is sleeved on the outer surfaces of both sides of the U-shaped anchoring tube, and the threaded limiting tube 52 is threadedly connected to both sides of the U-shaped anchoring tube.

[0025] It should be noted that the outer diameter of the threaded limiting tube 52 is smaller than the inner diameter of the plastic sleeve 51 , and a flange is provided on the outer surface of the threaded limiting tube 52 near the top end. When the threaded limiting tube 52 is rotated downward, the top of the plastic limiting tube contacts the flange.

[0026] When the device is fixed to the bottom of the structural plate 70, the threaded limiting tube 52 is rotated to make the plastic pipe collide with the bottom of the U-shaped anchor ring 20 downward. It should be noted that a release agent needs to be applied to the connection to prevent concrete from entering from here and making it impossible to recover it later. The flange further collide with its top. The interaction between the two fixes the plastic sleeve 51 on both sides of the U-shaped anchor ring 20 to avoid impact on it during subsequent concrete pouring, which will cause gaps for concrete to enter.

[0027] In this embodiment, the material of the plastic pipe is PVC plastic, which has good corrosion resistance, high strength, and low cost. When it is pre-buried in the structural plate 70, it will not affect the structural strength of the structural plate 70 later.

[0028] like Figure 3 As shown, the steel plate 10 is provided with a first embedding groove 102 and a second embedding groove 123 respectively from the two hinge grooves 101 along the length direction, and the first embedding groove 102 and the second embedding groove 123 are staggered with each other. It should be noted that the bottom length of the U-shaped anchor ring 20 is less than the length of the hinge groove 101, and the U-shaped anchor ring 20 can be moved in a small range in the front and rear directions of the hinge groove 101. When the two U-shaped anchor rings 20 are rotated 90 degrees toward each other, the U-shaped anchor ring 20 on the left is embedded in the first embedding groove 102, and the U-shaped anchor ring 20 on the right is embedded in the second embedding groove 123, thereby reducing its unfolding space for easy transportation. When unfolded to be perpendicular to the steel plate 10, the two U-shaped anchor rings 20 can be moved forward and backward to overlap in the length direction, so as to facilitate the fixation of the I-beam 60.

[0029] Specifically, the working principle of the U-shaped anchor ring of the cantilever scaffolding that can be used cyclically is as follows: when in use, unfold the two U-shaped anchor rings 20 to make them 90 degrees with the steel plate 10, then put the plastic sleeve 51 on both sides of the U-shaped anchor ring 20, and fix it through the threaded limit tube 52, and pre-embed the assembled device to the bottom of the structural plate 70, and apply the release agent at the same time. After pouring the concrete, fix the I-beam 60 through the steel pressure plate 30 and the double nut 40, so as to provide a fixing effect for it. When it needs to be removed, remove the double nut 40, the steel pressure plate 30 and the double nut 40 in turn. 0 and the threaded limiting tube 52, and then the steel plate 10 is removed from the bottom of the structural plate 70. At this time, the U-shaped anchor ring 20 is removed from the plastic sleeve 51, and finally the two U-shaped anchor rings 20 are folded into the first embedding groove 102 and the second embedding groove 123. Through the above structure, the U-shaped anchor ring 20 of the transmission is tightly connected with the structural plate 70 after the construction is completed, and the U-shaped anchor ring 20 needs to be cut when it is removed, which increases the difficulty of construction. Moreover, the U-shaped anchor ring 20 after cutting loses its value of reuse due to structural damage, resulting in a waste of resources.

[0030] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
