Description

A kind of prefabrication and assembly construction post and reinforced concrete foundation attachment structure and construction method
Technical field
The present invention relates to one kind can be effectively improved assembled post and armored concrete attachment structure Stress property and shock resistance Energy, enhancing structure globality, the assembled post and reinforced concrete foundation attachment structure and construction party for being easy to site operation tissue Method, belong to building engineering field.
Background technology
In recent years, developing rapidly with China's economy, building industrialization have obtained continuous development, assembly concrete Structure is to realize a kind of important feature of architectural industrialization development model, and its economic, convenient, environmentally friendly advantage has obtained both at home and abroad Very big concern.
The stressing conditions of assembled architecture component connecting node are complex, and there are some researches show fabricated construction is broken Connection between bad and different type component is in close relations.Assembled post is to influence assembled with armored concrete attachment structure The important node of building structure performance, attachment structure character and its anti-seismic performance are to influence the important indicator of the joint behavior, very The security of whole building can extremely be had an impact.
A kind of existing concrete column is connected with base node, it is characterized in that post, with basic complete cast-in-place, this connected mode is whole Body stability is relatively good, but the connected mode does not break away from wet node type of attachment, and on-site construction processes are complicated, construction period It is long, the advantages of assembled architecture is constructed can not be embodied.
A kind of assembly concrete post is connected with base node, it is characterized in that the hole for laying pillar is reserved in basis, The size of hole should be larger than pillar cross dimensions, and after pillar puts people's hole, pea gravel concreten is used around pillar(It is more mixed than basis Solidifying native intensity is high)Pour.Such a connected mode is simple to operate, easy for construction, but resistance to overturning is poor, and anti-seismic performance is not strong, Anti-impact shearing resistance breakout capacity is poor simultaneously.
In summary, some existing assembled posts and base node connection method, achieved under suitable operating mode compared with Good effect, but remain and can carry improving site operation efficiency, improving joints character, raising site operation quality etc. Rise part.In consideration of it, in order to further lift the globality of prefabricated concrete structure, shock resistance, urgently invent at present One kind can be effectively improved assembled post and armored concrete attachment structure Stress property and anti-seismic performance, enhancing structure globality, It is easy to the assembled post and reinforced concrete foundation attachment structure and construction method of site operation tissue.
