Description

Assembled beam-column connecting node and its construction method
Technical field
The invention belongs to prefabricated assembled concrete element structure technical field, connects more particularly, to a kind of assembled beam-column Connect node and its construction method.
Background technology
Assembly concrete building refers to based on the concrete prefabricated element with factorial praluction, pass through site-assembled side The concrete structure class building construction of formula design-build.The assembly method of component pours overlapping layer concrete, steel after typically having scene Pouring concrete connection etc. after muscle anchors, bar connecting can be connected, welded using sleeve grouting, mechanically connected and reserving hole overlaps The ways such as connection.In the 1980s, in the popular prefabricated big plate house in China, due to structural integrity is poor, seepage, The reasons such as cracks on floor slab, the hidden danger and defect of many influence structure safety and normal use be present, gradually by cast-in-place concrete knot Structure is substituted.But with the application of current emerging prefabricated concrete structure, particularly introduce in recent years many external first Enter technology, localized prefabricated concrete structure is built new technology and just gradually formed.
Precast reinforced concrete structure is one of important directions of China's building structure development, and it is advantageous to China's building Industrialized development, improve production efficiency and save the energy, develop Green environmental-protection building, and be advantageous to improve and ensure to build work Cheng Zhiliang.Compared with cast-in-situ construction method, assembled reinforced concrete structure is advantageous to green construction because fabricated construction can more meet it is green Saving land, save, saving the requirement such as material, water saving and environmental protection for color construction, reduces the negative effect to environment, including reduce and make an uproar Sound, airborne dust is prevented, is reduced environmental pollution, transport is cleaned, reduces place interference, saves resource and the energy such as water, electricity, material, abided by Follow the principle of sustainable development.Moreover, fabricated construction can continuously complete multiple or whole processes of engineering in order, from And the engineering machinery type and quantity marched into the arena are reduced, the time of resting of procedure connection is eliminated, realizes interchange operation, reduction is applied Worker person, so as to improve work efficiency, reduction supplies consumption, reduce environmental pollution, provided safeguard for green construction.In addition, assembled Structure largely reduces building waste (account for municipal refuse total amount 30% -40%), such as steel scrap muscle, waste iron wire, useless bamboo Timber, discarded concrete etc..
Although prefabricated integral frame structure there are many benefits, exist during practice of construction at connecting node Many technical barriers, lifting components are not easy to carry out construction positioning, and then reduce construction quality and efficiency of assembling;It is overall to assembling For formula frame structure, beam-post connection is construction key place again, and the bar connecting of beam-post connection is more using machinery at present Sleeve connection, be welded to connect or wet type connection etc. form;And these connecting nodes there is construction is complicated, power transmission not directly, The problems such as working procedure is more.
