A kind of manufacturing method of composite lightweight filling member

Abstract

A manufacturing method for a composite light filling component comprises the steps as follows: prefabricating a light internal mold; buckling the light internal mold; fixing the light internal mold; making a mixture of cement, mortar and glue; performing surface pretreatment, that is, spreading the mixture of the cement, the mortar and the glue, which is stirred well and in a semifluid state, onto the upper surface of the light internal mold; wrapping the light internal mold with a fiberglass mesh; performing surface treatment, that is, spreading the mixture of cement, mortar and glue, which is in the semifluid state, onto the lower surface and the peripheral side surface of the light internal mold to cover the fiberglass mesh; performing curing, that is, turning over the light internal mold after the mixture of the cement, the mortar and the glue on the lower surface is solidified and cured, and finally enabling the mixture of the cement, the mortar and the glue to form a hard inorganic composite layer on the outer surface of the light internal mold. The manufacturing method for the composite light filling component, provided by the invention, is simple, fast and reasonable in technological process; the composite light filling component manufactured according to the manufacturing method is reasonable in product structure, convenient for production and transportation and convenient and fast in construction.

Description

technical field [0001] The invention relates to a manufacturing method of a prefabricated building component in a cast-in-situ concrete hollow floor, in particular to a manufacturing method of a composite lightweight filling component. Background technique [0002] The advancement of construction technology promotes the diversification of building structures. Compared with traditional residential houses, buildings such as exhibition halls, gymnasiums, large conference venues, underground garages, and large shopping malls usually have the characteristics of large spans and large bays. In order to meet the load bearing requirements of the bay building structure, the floor slab structure is usually thicker, and the beams are wider and higher, so the overall weight of the floor slab is large, and the amount of concrete and steel bars is large. Under the premise of conforming to the stress of the building, in order to better reduce the structural weight of the concrete floor, con...
