Description
Technical field
The present invention relates to assembled hollow floor core model filler material, preparation method and assembled hollow floors, belong to building
Material Field.
Background technique
As domestic economy is horizontal and improvement of living standard, demand of the people to modern architecture is also more and more,
Ask also higher and higher, comfort level, environmental protection, economical rationality etc..
In building is built, traditional handicraft mostly uses greatly the hardened structure of cast-in-situ concrete beam, and there are many primary-secondary beam, appearance
Difference, building arrangements are bad, and from great, the utilization rate in space is not high, so that people are extremely difficult to desired effect when fitting up in the later period
Fruit.And speed of application is slow, site workload is very big, and the period of building built is longer, building waste and pollution the problems such as without
Method effectively solves, and hardly possible meets people to the timely demand in house and environmentally friendly needs.
Occur assembled hollow floor technology therewith, while solving the above problems, also there is prefabricated panel plate thickness
It is thicker, and need using core model pore-forming, and involved great expense using core model, core model is also easy impaired or is scrapped in construction, no
It is disconnected to require supplementation with new core model, cost is greatly improved, and be easy in pore-creating core construction along bad, construction trouble, construction speed
Degree is slow.In addition, hollow floor technique building technology used at present is more complicated, although construction period has compared to traditional handicraft
