Technical field
The present invention relates to a kind of aluminum alloy pattern plate arc in-situ beam casting method, particularly relate to based on sizing Quick Release aluminum alloy pattern plate arc cast-in-situ concrete beam and construction method.
Technical background
In recent years along with the progress of society, the raising of living standards of the people, house is no longer to only require simple house, being to start the variation of requirement building, diversification, the building of moulding uniqueness can be found everywhere, and beauty of architecture often embodies with curve, therefore Curved beam can be frequently encountered by structure construction, it is improper that this type of Curved beam template such as designs, and can cause that construction cost is big, the working procedure time is long, and construction quality it is difficult to ensure that.
Reinforced concrete cast-in-situ structure construction always payes attention in form work engineering frame structure engineering Curved beam the most either reinforced bar engineering or the construction of template, concrete works has the biggest difficulty.Owing in planar arc beam outer edge, each point is respectively positioned on the plane coordinates position being continually changing, especially oval beam, hyperbola beam, either all there is great difficulty with reinforcing location in the construction line-putting, model sheetinstallat.The Curvature varying of Curved beam is many, all brings the biggest difficulty to stencil design mark, the processing of arc formwork, and the material that arc formwork consumes is many, and construction cost is big.Normal floor structure construction flow beat is fast simultaneously, now spells template construction as arc side bar uses, can not catch up with structure construction flow beat, will affect overall structure construction speed.The most commonly used bamboo slab rubber smooth surface, the easy demoulding, flexible but be unfavorable for being accurately positioned of Curved beam side template.
In consideration of it, be difficult to control to for arc cast-in-place concrete beam template physical dimension, install the construction Difficulties such as complexity, needing a kind of speed of application of invention at present badly fast, construction quality is good, can realize the arc in-situ beam casting method of rapid construction.
