Cast-in-situ concrete filling thin-walled matrix and method for making same

Abstract

The invention discloses a thin-wall matrix for filling cast-in-site reinforced concrete and a manufacturing method thereof. The integrated matrix bottom plate and the ambient side wall are made of the mixture from hydration reaction, such as wet cement mortar and light cement mortar; then an inner mold support plate is hoisted and supported in or on an opening surrounded by the ambient side wall; then the top surface of the inner mold support plate is coated with the mixture from hydration reaction such as wet cement mortar and light cement mortar to form a top plate of the thin-wall matrix; when in forming, the periphery of the top plate and the corresponding wet ambient side wall are integrated into a whole body; the whole body is then let stand and maintained so that the bottom plate, the ambient side wall and the top plate are cured synchronously into a whole. The timing of the method for coating the cement mortar of top surface is to choose the wet condition where the ambient side wall has the substantially same physical and chemical properties as the top surface cement mortar. The method can achieve the integrated structure formed by the synchronous curing of the ambient side wall and the bottom plate, and overcomes the shortcomings with the prior manufacturing method.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a thin-walled carcass for filling cast-in-place concrete and a manufacturing method thereof. 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, this kind of thin-walled box is also provided with concrete pouring holes through the top and bottom plates of the thin-walled box to facilitate pouring and improve its mechanical performance. 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 pane...

Problems solved by technology

[0004] But still there is defective in said method: the cavity formwork member of its one side opening is made in advance, and finally forming wall is post-fabricated, even if material is identical, but the slurry of final forming wall is with hardened surrounding side when forming The physical and chemical properties of the wall are very different, and the wall with asynchronous hardening speed cannot be integrated with the surrounding side walls. Therefore, the final forming wall and the surrounding side walls are still two different components in the manufactured cavity formwork. , the above-mentioned manufacturing method can only ensure the tight combination of the final formed wall and the surrounding side walls, but cannot realize the real one-piece combination
