Prefabricated concrete integral athermal bridge slab wall and its vertical connection method

Abstract

The invention provides a vertical connecting method of a prefabricated concrete integral thermal-bridge-free plate wall. An upper layer integral thermal-bridge-free plate wall and a lower layer integral thermal-bridge-free plate wall are connected through an inner connecting rebar row and an outer connecting rebar row. Connecting points of the inner connecting rebar row are located in a common plane of a plate body bottom face and the top face of an inner concealed column row. Connecting points of the outer connecting rebar row are located in a common plane of a plate body top face and the top face of the inner concealed column row. Connection is conducted mainly through the inner connecting rebar row and the outer connecting rebar row. The vertical connecting method of the prefabricated concrete integral thermal-bridge-free plate wall has the effects and advantages that the wall integral synergistic performance is good, the energy-saving performance is high, the integral thermal-bridge-free technology and an enhanced concealed column system are adopted, thermal bridges can be effectively cut off, and a good insulation property is achieved; and the anti-seismic property is remarkably improved, the number of connecting pieces is greatly reduced, construction is simplified, the industrial efficiency of the vertical connecting method is remarkably promoted, and the resource and energy consumption is reduced. In addition, the connecting method is suitable for dry operation and complete assembling of prefabricated concrete structures.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a prefabricated concrete integral heat-free bridge slab wall and a vertical connection method thereof. Background technique [0002] Prefabricated concrete buildings refer to prefabricated concrete components produced in factories. Concrete structure housing buildings designed and constructed through on-site assembly. At present, the assembly methods of components generally include on-site post-casting laminated concrete, steel bar anchoring and post-casting concrete connection, etc. The steel bar connection can be connected by sleeve grouting, welding, mechanical connection and lap connection with reserved holes. In the 1980s, prefabricated prefabricated large-slab houses, which were popular in my country, had many hidden dangers and defects that affected structural safety and normal use due to poor structural integrity, leakage, and floor cracks, and were gradual...

AI Technical Summary

Problems solved by technology

Insufficient research on the integrity of seismic resistance of prefabricated structures and specialized research on design and construction management has resulted in poor technical and economical performance of prefabricated structures, resulting in long-term stagnation of prefabricated structures

For this reason, it is necessary to carry out industrialized systematic research and development aimed at the shortcomings of existing buildings, such as poor mechanical performance and poor seismic performance, so that my country's construction industry can truly realize the green, recyclable and sustainable construction process in the whole process.
