Description

Prefabricated PC beams of concrete column connected node and construction method

Technical field

The present invention relates to assembled arthitecutral structure dry type connecting node technical field, more particularly to a kind of prefabricated PCs Beams of concrete column connected node and construction method.

Background technology

With the fast development of China's economy, living standards of the people are constantly promoted, and the requirement to house increasingly improves.Together When, the cast-in-place construction mode and China's sustainable development idea of house are incompatible.Currently, China's house in the urgent need to address is built If middle high energy consumption, high pollution, it is with high investment the problems such as, so house town and country construction portion of State Development and Reform Commission of China promulgates《Green is built Build action scheme》, the buildings such as the prefabricated assembled concrete structure for being suitble to industrialized production, steel construction are promoted wherein specifically mentioning System accelerates development the prefabricated and mounting technology of construction project, and it is horizontal to improve building industrialization Integration ofTechnology.

Prefabricated assembled concrete structure has the following advantages:

(1) green construction.Prefabricated concrete structure construction can more meet saving land, is energy saving, saving material, is water-saving for green construction With the requirements such as environmental protection, the negative effect to environment is reduced, including reduces noise, prevents airborne dust, reduces environmental pollution, cleaning Transport reduces place interference, saves resources and the energy such as water, electricity, material, it then follows the principle of sustainable development.

(2) short time limit.Since a large amount of assembly concrete component is all in plant produced and maintenance, what construction site carried out Work is only to lift the prefabricated component of precast plant, assemble, joint reinforcing, is not only not necessarily to install scaffold and branch Support, and reduces influence of the seasonal factor to the construction period, agent structure be molded laggard luggage repair, the work such as Hydroelectric Project Construction, Workload is constructed much smaller than cast-in-place method, or even is eliminated and built by laying bricks or stones and plastering process, therefore substantially reduces the whole duration.

(3) component quality is good.Concrete in precast plant need not pump, and the water in concrete is less, concrete strength Grade is higher than cast in situs.After precast plant has poured component, component is just subjected to steam curing, ensures concrete quality, And construction site curing concrete can not only provide steam-cured excellent condition, but also be influenced by weather, maintenance quality without Method is compared with precast plant.

But prefabricated assembled concrete structure also has some disadvantages of its own, such as node type of attachment complexity.Mesh Preceding main connecting node form needs live assembling reinforcement, casting concrete, and need scaffold, template etc., this gives node Quality bring hidden danger, to construction technical requirement height, limit the use of precast concrete to a certain extent.
