Abstract
The invention discloses a design and construction method of an assembly type UHPC shell. Through one mold, multiple shell units are made, the manners of factory fabrication and site assembling are adopted, repeated assembling can be achieved, and the method is technically characterized in that firstly, the multiple UHPC shell units form an outdoor building with a space enclosure feeling, and multiple combination manners are achieved; secondly, a numerical control hot linear cutting machine tool is adopted for making an EPS plastic conformal single-face mold, and the surface is smooth; thirdly,on the basis of the conformal mold, the injection process is adopted for making a concrete negative single-face mold; fourthly, on the basis of the negative mold, the ink jet process is adopted for making the UHPC shell units; and fifthly, a metal connecting part is arranged on the construction site ground, and is fixed to metal connecting parts on the edges of the shell units, and site assembling is facilitated. The large shell structure is built through the small mold, and multiple combination manners exist between the shell units.
Description
technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a design and construction method of an assembled UHPC thin shell. Background technique [0002] The construction of the thin shell structure generally adopts the construction method of cast-in-place, which requires a large mold area and a curved shape. The pouring process requires the mold to have high strength and precision, and it is generally made of wood. Since the molds required for each engineering project are different, the molds cannot be reused. Under the current process conditions, the material cost and production cost of the mold are relatively high, and the one-time use method causes a waste of resources. [0003] In the thin shell engineering project, the shape design of the thin shell is first carried out by the architect, followed by the mechanical checking calculation by the structural engineer, and finally the thin shell is built by the mater...
