Description
Technical field
The invention belongs to construction engineering technical field, more particularly to a kind of assembly concrete frame structure beam column rigidly connects
Connect node.
Background technology
With the fast development of China's economy, living standards of the people are constantly lifted, and the requirement to building is increasingly improved；Together
When, the cast-in-place construction mode of building and China sustainable development idea are incompatible.At present, 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, therefore, house town and country construction portion of State Development and Reform Commission of China is promulgated《Green is built
Build action scheme》, wherein specifically mentioning the buildings such as prefabricated assembled concrete structure, the steel construction for promoting suitable industrialized production
System, accelerates development the prefabricated and mounting technology of construction project, improves building industrialization Integration ofTechnology level.Wherein, prefabricated dress
There is advantages below with formula concrete structure：
(1) green construction.Prefabricated concrete structure construction can more meet saving land, save, saving material, water saving for green construction
Required with environmental protection etc., reduce the negative effect to environment, including reduction noise, prevented airborne dust, reduce environmental pollution, cleaning
Resource and the energy such as transport, the interference of reduction place, saving water, electricity, material, it then follows the principle of sustainable development.
(2) short time limit.Because substantial amounts of assembly concrete component is all in plant produced and maintenance, what job site was carried out
The prefabricated component of precast plant is only lifted, assembled by work, joint reinforcing, need not only install scaffold and branch
Support, and influence of the seasonal factor to the construction period is reduced, the work such as the laggard luggage of agent structure shaping is repaiied, 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 overall duration.
(3) component quality is good.Concrete in precast plant need not be pumped, and the water in concrete is less, concrete strength
Grade is higher than cast in situs.Precast plant has been poured after component, component just is carried out into steam curing, it is ensured that concrete quality,
And job site curing concrete can not both provide steam-cured excellent condition, and influenceed by weather, maintenance quality without
Method is compared with precast plant；And precast concrete column is that level is poured when precast plant is prefabricated, and whole long column is integrally formed, energy
Ensure its globality.
But, prefabricated assembled concrete structure also has some shortcomings of its own, and such as node type of attachment is complicated.Mesh
Preceding main connecting node form needs live assembling reinforcement, casting concrete, and needs scaffold, template etc., and this gives node
Quality bring hidden danger, it is high to construction technical requirement, the use of precast concrete is limited to a certain extent.Except scene is tied up
Outside the node wire-tie, also there is part other forms connecting node, for example with the pre-buried shaped steel in concrete beam and column node area, lead to
Prestress wire is crossed by beam-to-column joint, this construction needs also exist for scaffold or other auxiliary equipment sling precast beam, treats
Prestress wire plays a role the dismountable scaffold in rear or auxiliary equipment completely, greatly reduces speed of application.
