Preparation method of cast-in-place concrete filling thin wall carcass

Abstract

The invention discloses a thin wall tyre body manufacture method used for the filling of the cast-in-place concrete. A tyre body bottom plate and the peripheral side walls which are connected into a whole body are manufactured with hydration reaction mixture such as wet cement mortar and light cement mortar, one or more inner mold holding plate(s) can be covered on the opening surrounded by the peripheral side walls, at least one side edge of the inner mold holding plate is extended outside the side wall of the tyre body side, and hydration reaction mixture such as wet cement mortar and light cement mortar is coated on the top surface of the inner mold holding plate to form the top plate of the thin wall tyre body; when the peripheral of the top plate is formed, except the extended side edge of the inner mold holding plate, all other side walls of the tyre body are integrated with the type body side walls with the corresponding positions under the wet state into a whole body, after the pre-hardening of each surface of the thin wall tyre body, the inner mold holding plate is drawn out, the thin wall tyre body manufactured by the invention is the seamless body structure, and the inner mold holding plate can be repeatedly used.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for manufacturing a thin-walled carcass for filling cast-in-place concrete. Background technique [0002] In the production or construction process of reinforced concrete hollow slabs, some lightweight materials are filled in the concrete to reduce the weight of the structure and improve the thermal insulation, heat insulation, and sound insulation effects of the concrete. Most of the filler blocks are hollow. Thin-walled box. Due to the limitation of the demoulding process, the inner cavity of the existing thin-walled box cannot be formed by the demoulding or pouring process at one time, so the existing thin-walled box is made of multiple prefabricated wall panels and prefabricated shells, and the joints are coated with cement Or glue splicing and bonding, because the prefabricated wall panels and prefabricated shells are already in a hardened state during b...

Problems solved by technology

[0004] But above-mentioned method and the product that uses this method to make still have defect: the cavity formwork member of its one side opening is made in advance, and the final forming wall is after making, even if material is the same, but the slurry of final forming wall is forming The physical and chemical properties of the hardened side walls are very different from those of the hardened surrounding walls, and the walls with asynchronous hardening speeds cannot be integrated with the surrounding side walls. They are still two different components. The above-mentioned manufacturing method can only ensure the tight combination of the final formed wall surface and the surrounding side walls, and cannot realize the real integrated combination; Each cavity formwork member needs a formwork, and the formwork cannot be reused, so a large amount of formwork material will be consumed to increase the manufacturing cost
