Embodiment Construction
[0026] The present invention is further illustrated by specific examples below.
[0027] A construction method of a flower basket-type cantilevered scaffold, comprising:
[0028] Step 1. Pre-embedded anchor bolts:
[0029] Pre-embed 2*M20 anchor bolts on the side of the beam or wall to connect the I-beam to the side of the beam or wall; among them, the pre-embedded bolts on the side elevation, according to the wall thickness or beam width, are divided into two forms of pre-embedded, including When the anchorage point of the cantilever beam or tie rod is the beam or shear wall width>200mm, use the embedded casing in the structure, the bolt does not penetrate the structure, and is fixed with the section steel, the cantilever I-beam is embedded in the positioning steel thread inner wire casing , the size is 180mm long, the diameter is 23mm, and there are built-in matching screws, which can be used for structural beams, walls and columns; when the cantilever beam or tie rod ancho...

The invention relates to the technical field of building construction, in particular to a construction method of a flower basket type cantilever scaffold. The method comprises the steps that firstly, anchor bolts are embedded; secondly, the cantilever I-shaped beam is installed; step 3, erecting a scaffold; step 4, mounting a pull rod; compared with a traditional cantilever steel wire rope, the pull rod is more convenient to fasten, has specific torque requirements and is safer. The flower basket type cantilever scaffold does not affect outer wall masonry construction of a cantilever layer, an outer wall does not need to be holed, and the hidden danger of outer wall leakage caused by hole repairing can be greatly reduced. The pull rod is fastened through the flower basket sleeve, the stress state of the pull rod is easier to guarantee compared with a steel wire rope, the iron sleeve is embedded in the upper end of the pull rod, and holes do not need to be formed in a formwork; compared with a traditional cantilever profile steel fixing mode, the use amount of profile steel can be greatly reduced, all components can be manufactured in a finalization mode, the turnover frequency is large, cost is saved, and attractiveness and practicability are achieved.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method of a flower-basket-type cantilevered scaffold. Background technique [0002] Cantilevered scaffolding refers to the scaffolding in which the frame structure is unloaded on the rigid cantilever beam (frame) attached to the building structure. [0003] The traditional cantilever method is to use pre-embedded U-bolts on the floor to fix the I-beams. The I-beams cantilever out of the structure, and scaffolds are erected on the cantilevered section. This method affects the masonry construction of the outer wall in the cantilever layer, and the outer wall needs to leave an I-beam hole, which greatly increases the hidden danger of leakage of the outer wall caused by repairing the hole, and the cantilever layer needs to be reserved due to the influence of the I-beam. Subsequent construction has a great impact on the construction period, such as fine d...
