The novel full assembly concrete frame joint of one kind and its construction method
Technical field
The present invention relates to building structure technology field, more particularly to a kind of novel full assembly concrete frame joint and its
Construction method.
Background technique
With the development of modern industrial technology, China starts to greatly develop assembled architecture, pushes industry restructuring liter
Grade.Compared with traditional cast-in-place structural, assembled architecture has construction speed fast, high production efficiency, saves labour, improves building
The advantages that quality.But China's assembled architecture is started late, and technology also falls behind relatively, to find out its cause, its restraining factors is to close
The node connectivity problem of key, structural integrity and anti-seismic performance are bad, and node construction is not easy.
For prefabricated assembled concrete structural system, the connection type between prefabricated components is assembly concrete
One of key problem of structural research.In general, the connection of prefabricated concrete structure prefabricated components can substantially be divided into involvement
It connects and 2 kinds of wet connection.In order to guarantee the globality of assembled architecture, the connection type of prefabricated components mainly uses wet company at present
It connects, i.e., is anchored in node point connection casting concrete or cement slurry with it when component is connected, form a variety of node types.It is dry
The connection type of the i.e. dry operation of connection, not casting concrete when connection, but by the component in connection be implanted into steel plate or its
His steel part, is bolted or welds to achieve the purpose that connection, application are relatively fewer.For assembled architecture, not only
Need to consider the safety and reliability of assembled architecture node, the convenience for also needing to consider simultaneously to build.Recognized based on this,
Efficient and convenient dry connecting node is researched and developed to be of great significance.
