Construction method of spatial mismatch cantilevered terraces of building

Abstract

The invention discloses a construction method of spatial mismatch cantilevered terraces of a building. The construction method of the spatial mismatch cantilevered terraces of the building comprises the steps that 1, terrace construction formworks are positioned; 2, a first mismatch terrace unit section is constructed; 3, the next mismatch terrace unit section is constructed; 4, prestressed diagonal tie rods are installed in a previous mismatch terrace unit section; 5, the terrace construction formworks below the cantilevered terraces in the previous mismatch terrace unit section are removed;6, steps 3-5 are carried out repeatedly until the floor cantilevered terraces are constructed; and 7, the remaining terrace construction formworks are removed. According to the construction method ofthe spatial mismatch cantilevered terraces of the building, segmentation construction is carried out by dividing the spatial mismatch cantilevered terraces into a plurality of mismatch terrace unit sections, and meanwhile, the prestressed diagonal tie rods are additionally arranged between the constructed cantilevered terraces and a main structure of the building for reinforcement, the bearing capacity of the cantilevered terraces is improved, the cantilevered terraces are enabled to directly bear the vertical load on the upper part, and the lower terrace construction formworks can be removedin advance, so that the turnover of facility materials of the terrace construction formworks is accelerated.

Description

technical field [0001] The invention belongs to the technical field of construction of an external cantilevered structure of a building main body, and in particular relates to a construction method for a building space dislocation cantilevered terrace. Background technique [0002] In construction projects, aerial cantilever structures are often designed, especially in recent years, high-end residential buildings, office buildings and public buildings have emerged with multi-level and multi-standard large cantilevered terrace structures. Due to the complex construction environment of the formwork of the high-altitude cantilever structure, the risk is high and the difficulty is high, and before the concrete reaches the design strength, especially when the upper part of the formwork is continuously constructed, the supporting system of the lower part of the component cannot be removed in advance, resulting in Occupied facilities have a long turnaround period for materials and ...

AI Technical Summary

Problems solved by technology

For the method of removing the formwork and support system in advance, most of them use the scaffolding pole of the support system to install early dismantling components to realize the early removal of the bottom formwork of the component, but the support frame cannot be removed in advance

Or use the method of replacing the support, that is, when the concrete reaches a certain design strength, use another more economical material and method to support the component, remove the original support system, and wait until the superstructure is completed and reaches the formwork removal strength. , can be completely dismantled, the risk of structural quality control and construction safety is relatively high, and the construction cost is high
