Embodiment Construction
[0025] Attached to the following Figure 1-2 This application will be described in further detail.
[0026] The embodiment of the present application discloses a diagonal bracing transition method for accelerating the erection of an overhanging scaffold. refer to figure 1 and figure 2 , the diagonal bracing transition method to speed up the erection of cantilevered scaffolding includes the following steps:
[0027] S1. According to the floor plan, pre-embed positioning bolts at a distance of 100mm from the outer edge of the corresponding ring beam steel bars. There are two positioning bolts, and the positioning bolts are welded and fixed on the steel bars.
[0028] S2, pouring the first layer of ring beam concrete, after the concrete reaches a certain strength of more than 75%, install the I-beam base 1, fix the base 1 on the positioning bolts, and install the anchor bolt plate on the base 1. In this embodiment The anchor plate is an ear plate, and the anchor plate is fix...

The invention discloses an inclined strut transition method for accelerating erection of a cantilever scaffold, and relates to the technical field of building construction. The inclined strut transition method comprises the following steps that positioning bolts are pre-buried in the positions, away from the outer side edges, on corresponding ring beam reinforcing steel bars, and the positioning bolts are welded and fixed to the reinforcing steel bars; a first layer of ring beam concrete is poured, and I-shaped steel bases are installed through positioning bolts; after a floor type double-row scaffold vertical rod erecting line is lofted around the ring beam by one circle away from the outer side of the ring beam, a floor type scaffold is started to be erected to the second layer or above, and then formwork and reinforcing steel bar construction of beams, columns and plates of the second layer is conducted; after the embedded holes of the I-shaped steel cantilever beam are positioned and installed, second-layer concrete pouring is conducted; the part, extending out of the structure, of the cantilever beam and the first-layer base are anchored and bolted together through I-shaped steel inclined struts; after all the inclined struts are installed, the floor type scaffold is converted into the overhanging type scaffold; when the floor is poured to more than four floors, cable-stayed steel wire ropes are additionally arranged; and finally, the I-shaped steel inclined struts and the base on the first layer are removed.
Description
technical field [0001] The present application relates to the technical field of building construction, in particular to a diagonal bracing transition method for accelerating the erection of cantilevered scaffolding. Background technique [0002] Cantilevered scaffolding refers to the scaffolding in which the frame structure is unloaded on the rigid cantilever beam attached to the building structure. It is used for the operation of the main body or decoration project in construction and its safety protection needs. The building structure attached to the cantilever frame It should be a reinforced concrete structure or a steel structure, and should not be attached to a brick-concrete structure or a stone structure. The supporting structure of the cantilever frame should be a cantilever beam or cantilever truss made of section steel, and steel pipes should not be used; its nodes should be bolted or welded, and fasteners should not be used. The fixing method with the building s...
