A fully dry prefabricated concrete slab-column structure system

Abstract

The invention discloses a full-dry-type prefabricated concrete slab column structure system, and belongs to the field of building structure technologies and structural seismic resistance and reduction. The full-dry-type prefabricated concrete slab column structure system comprises prefabricated columns with connecting flat plates and combed joints, prefabricated floor slabs, prefabricated wall plates provided with elliptical holes filled with ECC materials, plate-plate connecting pieces, wall-plate connecting pieces and the like; the prefabricated columns and the connecting flat plates are overall poured, the prefabricated floor slabs are matchboards, the prefabricated wall plates are cold-formed thin-walled steel composite wall plates, and the connecting flat plates, the prefabricated floor slabs and the prefabricated wall plates are connected through the connecting pieces; and the plate-plate connecting pieces and the wall-plate connecting pieces are both composed of anchor plates and anchor bars, poured with components integrally, and anchor plate connecting components are welded on a construction site. According to the full-dry-type prefabricated concrete slab column structuresystem, full-dry-type construction is achieved, wet operation is omitted, construction is easy and convenient, the prefabrication rate is high, the construction efficiency is greatly improved, the cost is low, and the full-dry-type prefabricated concrete slab column structure system has the characteristics of safety, reliability and good seismic resisting performance.

Description

technical field [0001] The invention relates to an all-dry prefabricated concrete slab-column structure system, the main components of which can be prefabricated in a processing plant, and no wet operation such as pouring concrete is required during the construction process, the construction project is simple and fast, and the construction efficiency is high. It meets the bearing capacity requirements under normal use conditions, is safe and reliable, and has good ductility and energy dissipation capacity under earthquake action, which greatly improves the seismic performance of traditional prefabricated concrete slab-column structures. The invention belongs to the field of new building structure technology and structure anti-seismic shock absorption. Background technique [0002] In recent years, my country has vigorously promoted the industrialization of construction and housing, and the prefabricated concrete structure has become an important form of industrialization of ...

Problems solved by technology

At present, the slab-column joints, multi-panel joints and wall-slab connections of prefabricated concrete slab-column structures mostly use post-cast concrete connection methods, and the wet connection construction period is long. Under the action of earthquakes, damage often occurs first, leading to structural failure. The construction efficiency and seismic performance of the structure still need to be improved. However, there are few related research and development in this area in my country.
