Connecting structure and construction method of precast concrete plates and beams, and building comprising same

Abstract

The invention relates to a connecting structure of precast concrete plates and beams. The precast concrete plate has a reinforced concrete structure, the end parts of the two precast concrete plates are respectively overlapped on both sides of the top surfaces of the beams, overlapping layers for connecting the beams and the precast concrete plates together are arranged above the precast concrete plates and the beams, and the overlapping layers are made of concrete cast on a construction site and internally comprise overlapping layer steel bars crossing the beams. The invention also relates to a construction method of the connecting structure, and a building comprising the connecting structure. The precast concrete beams and the precast concrete plates can form a unified body through the overlapping layers cast on the construction site, ensuring the safe reliability of the precast concrete beams and the precast concrete plates on stress. Cracking, malposition and other situations of the end parts of the precast concrete plates on plate and beam connecting parts can be prevented through reinforcing steel bars and the overlapping layer steel bars.

Description

technical field [0001] The invention relates to the field of construction, and more particularly, to a connection structure, a construction method and a building of a prefabricated concrete beam. Background technique [0002] With the rapid development of China's urbanization, the urban population density is increasing, people's demand for housing is becoming more and more urgent, and the buildings are high-rise, large-scale and complex. Traditional buildings are completed through on-site construction (such as on-site casting of concrete frames, floors, etc.), which not only has construction quality risks due to the technical level of construction personnel, but also has the problem of low construction efficiency. [0003] Construction industrial production technology refers to the centralized production and processing of various building components (such as columns, beams, floors, etc.) in factories, and on-site transportation, assembly and construction. The use of buildin...

Problems solved by technology

[0005] In the past, a large number of hollow prefabricated floor slab technologies appeared in China. In this technology, each hollow-core slab is structurally independent, there is no cast-in-place laminated layer, and it is also in a general lap relationship with structural beams, resulting in the gap between floors and floors. Can not form a unified whole with the beam, easy to crack, leak and damage
