Technical field
The invention belongs to building engineering field, the conversion layer structure that is related in building structure, and in particular to watered after a kind of The double-deck RC plate-type transfer floor and construction method of portion's structure.
Background technique
Conversion layer is set in figure complexity, the diversified building of functional requirement, is that structural engineer is upper and lower in order to realize Layer structure type conversion, column net, the axis of upper and lower layer change or transformational structure form and structure axis are arranged and taken simultaneously Effective ways.Since 20th century five, the sixties propose conversion layer structure concept, the analysis means and design of conversion layer structure Technology is more and more diversified, also increasingly tends to be mature so that conversion layer structure obtained in modern high-rise building it is more next More it is widely applied.Common several conversion layer structures include transfer beam, truss conversion, Box-transfer storey, thickness in current engineering Plate conversion etc..The above conversion layer structure adapts to different buildings and its functional requirement.Currently with the rapid development of economic construction, it deposits In a class formation putting into effect in advance due to bottom, and superstructure then needs later period planning construction, therefore conversion layer just needs The building for adapting to superstructure bodily form complexity, to meet the needs of practical structures.
Slab transformational structure is as shown in Figure 1, the structure is the form for being easiest to meet building function requirement in transformational structure. When upper and lower layer column net axis misalignment is more or top shear wall structure arrangement very irregular and infrastructural requirements arrange huge pillar Net and when being difficult to support direct with beam, is a kind of preferable structure type using transfer slab.It is using the advantages of transfer slab Upper and lower structures flexible arrangement, it is not necessary to consistency from top to bottom;The disadvantage is that from great (up to thousands of tons of), cost is high, construction when formwork, Reinforcing bar binding is difficult, and the series of problems such as construction for being related to mass concrete.In design, due to the power transmission road of thick transfer slab Diameter is not apparent, and local stiffness is excessive, and stress is complicated, temporarily available without mature simplification method, so that Structure Calculation is very multiple It is miscellaneous;Due to design shearing resistance and Punching Shear needs, the thickness of change-over panel is very big, this cause change-over panel quality and rigidity mutation, The reaction increase of structure, the neighbouring layer of conversion layer more become weak floor when geological process, are unfavorable for earthquake-resistant structure.Another party Face, due to the increase being self-possessed with geological process, the load of lower part vertical structure is obviously increased, and design difficulty is with increase.Research Show that internal force and the displacement of thick transfer slab are extremely uneven, maximin can differ tens times, need to can adopt by improvement With.
