Description
Technical field
The present invention relates to a kind of cost that is applicable to and require lower villages and small towns regeneration concrete framework, the steel of framework-shear wall earthquake resistant structure-regeneration concrete combination power consumption to support, belong to technical field of structural engineering.
Background technology
Along with quickening of urbanization process, the annual concrete amount of China has surpassed 10 billion cubic meters, consumes a large amount of primary resources such as sandstone.Simultaneously, owing to reasons such as the renewal of urban architecture, transformations, a large amount of existing concrete are removed, and have formed the surprising discarded concrete building waste of quantity.Being the exploitation of a large amount of natural resources on the one hand, is the generation of a large amount of discarded concrete building wastes on the other hand, how to realize building waste discarded concrete resource, is to concern builing industry STRATEGIES OF SUSTAINABLE DEVELOPMENT property significant problem.
Regeneration concrete is a kind of green concrete, is with after waste concrete block fragmentation, cleaning, the classification, mixes according to a certain percentage to form regeneration aggregate, then it is partly or entirely replaced the formulated regeneration concrete of natural aggregate.China's house and town and country construction portion have issued industry standard " regeneration aggregate application technology rules " (JGJ/T240-2011) in 2011; Provincial standard " regeneration concrete application technology rules " has been issued (DG/TJ08-2018-2007) in the area, Shanghai in 2007; " regeneration concrete structure design rules " have been issued (DB11/T803-2011) in the Beijing area in 2011, using in Structural Engineering for regeneration concrete provides technical basis.
China is the country of shake more than; After Tangshan Earthquake; Tens ruinous earthquakes take place in continent area altogether; And wherein great majority occur in the area, villages and small towns that economic technology falls behind relatively, cause bigger life and property loss, so the antidetonation ability of taking precautions against natural calamities of villages and small towns building also more and more receives national the attention.And build for villages and small towns building disaster prevention antidetonation, local economy and technical level backwardness are key constraints wherein.
Anti-buckling energy-consumption supports mainly to be made up of kernel power consumption unit, peripheral constraint element, double structure lateral resistant member and the power consumption member done.Tradition supports and compares, and its kernel unit is owing to limited by peripheral constraint element, only produces surrender during pressurized and flexing does not take place, thereby surrender effective earthquake energy through the kernel unit tension and compression.But anti-buckling energy-consumption supports peripheral constraint element and is generally concrete filled steel tube, so it has following shortcoming: 1. kernel unit and peripheral constraint element adopt steel and steel pipe usually, thereby rolled steel dosage is bigger, and cost is higher; 2. need when making non-cohesive material to be set on the kernel unit surface; Concreting forms peripheral constraint element in steel pipe afterwards; But in the process of vibrated concrete, cause the damage of non-cohesive material easily, so its production process complicacy and the difficult assurance of final mass.And for the villages and small towns building, the power consumption that the cost cost is high, production process is complicated is supported and is not suitable for actual demand.
Summary of the invention
The object of the invention be to provide a kind of have make simple, cheap, the power consumption effect is good; Increase the anti-side rigidity of structure during little shake; In when shake open and close with the end rubber pad distortion and consume energy through supporting distress in concrete; During big shake through support the mild steel yield deformation, distress in concrete opens and closes and end rubber pad distortion power consumption, that the shake back is changed is easy, cost is low, is applicable to that the villages and small towns regeneration concrete framework of low cost, the steel of frame shear wall structure-regeneration concrete combination power consumption support.
