Below in conjunction with accompanying drawing and specific embodiment, the Crack Control structure of overlength super high thin wall clear-water concrete of the present utility model is described in detail.
The alien invasion dry wall overall height of this project reaches 34.3m, and total elongated surfaces reaches 400m, and body of wall gross thickness only has 180mm, belongs to all rare overlength super high thin wall bare concrete wall both at home and abroad.
For the body of wall of this type, from the viewpoint of general structure designs such as concrete retractilities, revulsion all can be set, initiatively to eliminate distress in concrete hidden danger.
But because this body of wall belongs to clear-water concrete, the faced concrete surface after having built does not allow to occur any flaw, more can not occur crack, thus just there is larger contradiction in structure and building two specialties in construction.How to balance two professional requirements, become us and tackle the most important problem of overlength super high thin wall clear-water concrete Crack Control.
According to the feature of this body of wall, because short transverse carries out construction in layer by horizontal exposed joint strip, individual layer construction height is 4.2m, and due to single, to build the possibility occurring crack extremely low in individual layer altitude range, and thus crack mainly easily appears at length direction.
The ultralong thin walled clear-water concrete of superelevation of this project, structure design is for such bare concrete wall, the spacing that revulsion is set is explicitly called for be about 18m, but consider according to aspects such as overall construction deployment and color homogeneities, on-the-spot practice of construction single builds length at least needs 100m, arranges revulsion like this with regard to having at the vertical position of length direction.
