Description

Assembled cable concrete building structure
Technical Field
The invention belongs to the technical field of building structure design, and relates to an assembled steel cable concrete building structure.
Background
At present, domestic fabricated buildings can be divided into fabricated cast-in-place systems, fabricated shear wall systems and fabricated frame systems, but the overall quality is not very considerable. The main reason is that the cast-in-place member in the original drawing is designed to be disassembled instead of adopting the design idea of the fabricated building, and the following problems exist:
at present, the components are connected by adopting a concrete cast-in-place mode, the connection standards of all the places are different, the country does not have unified standards and acceptance standards, and the mode is greatly influenced by temperature and humidity. The quality of the fabricated construction project cannot be generalized from place to place.
The acceptance standard of the construction quality needs to be improved. The connecting steel bars of the prefabricated parts are bent frequently in the transportation process, so that in the normal construction process, workers can shear the steel bars because the steel bars of the prefabricated parts cannot be inserted into the reserved hole seams of the prefabricated parts, and the connection quality is difficult to guarantee.
The grouting process on site is still immature, grouting is likely to be insufficient, and air bubbles are left, so that the construction quality problem is difficult to guarantee.
The energy consumption is large in the construction process, and the generated construction waste is more, so that the requirement of environmental protection is not met.
