Description
Technical field
The invention belongs to building structure construction technical field, be specially and be a kind ofly applicable to industry and use the site operation technology of prefabricated energy-conservation Cavity structural member with cast-in-situ concrete close rib cavity building roof in civilian construction.
Background technology
Along with rapid development of economy, urbanization process is constantly accelerated, and population is assembled rapidly to city, and urban architecture more and more can not meet the demand of people to space, and urban architecture is just making great efforts to expand towards many, high-rise.
The quickening of urban construction also facilitates the many revolutionary breakthroughs of Building technology, and the hollow building cover technology of one of them is noticeable with its unique advantage.
Hollow building cover technology comes from 60, the pre-stress hollow concrete prefabricated board of the seventies, the method burying hollow circular-tube core fluid concrete again underground is adopted to become the second generation product of hollow building cover afterwards, finally develop into present stage and bury hollow box body third-generation technology cast-in-place again underground, the replacement of product has also promoted the innovation of construction technology, such as my patent No. of collaborative application is ZL200410077594.2, name is called the patent of " a kind of cast-in-place concrete hollow building roof construction technique ", the remarkable advantage of third generation product is then embodied in and can meets the requirement of building to large-span, decrease concrete consumption to greatest extent, water resistance and anti-seismic performance good, and this have also been obtained confirmation in practice.
Along with the appearance of a series of energy-saving and emission-reduction scheme of country, the development of constructional materials energy-saving has been trend of the times.Although common hollow building cover technology steps a stage than conventional art in insulation, sound insulation, breakthrough product is still rarely seen, particularly carries the heat treated product of thermal insulation separation for structure then more rare.Based on country's improving constantly building energy conservation target, improve existing hollow building cover noggin piece and site construction technology and make overall floor have better energy-saving effect for being badly in need of.
Summary of the invention
The present invention seeks to the construction method that will provide a kind of energy-conservation close rib cavity floor, floor carries thermal insulation process, makes floor gap produce the energy-saving effect of bridge cutoff type.
The object of the invention is by following technical solution and realize: a kind of construction method of energy-conservation close rib cavity floor, comprises the steps:
