Abstract

The invention discloses a membrane shell material used for a multi-ribbed floor system. The membrane shell material comprises the following raw materials in parts by weight: 40 to 60 parts of aluminoferrite cement, 20 to 25 parts of fluorgypsum, 20 to 25 parts of composite gypsum, 6 to 10 parts of fly ash, 10 to 15 parts of glass fiber gridding cloth, 5 to 10 parts of chopped glass fibers, 10 to 20 parts of glass water, 2 to 5 parts of a coagulant and 40 to 60 parts of water. The preparation method comprises the following steps: (1) weighing all raw materials; (2) stirring the aluminoferrite cement, the fluorgypsum, the composite gypsum, the fly ash and a first part of the glass water, and carrying out standing; (3) adding the chopped glass fibers, a second part of the glass water, the coagulant and the water; and (4) uniformly spraying an obtained mixture into a mold by a plurality of times, and carrying out drying in the air, and carrying out molding. The membrane shell used for themulti-ribbed floor system does not absorb water or seep water, is light in material, short in molding period, high in strength, firm and durable, and can be widely applied to large-span and large-baycast-in-place reinforced concrete multi-ribbed floor buildings in industrial and civil buildings.

Description

technical field [0001] The invention relates to the technical field of building materials, and more specifically relates to a membrane shell material for a ribbed floor, a membrane shell containing the same and a preparation method thereof. Background technique [0002] The densely ribbed floor refers to a one-way or two-way ribbed floor with a rib spacing ≤ 1.5m. It is composed of thin slabs and rib beams with small spacing. Among them, the load transfer method of the two-way densely ribbed floor system is to act in two directions at the same time, and the mechanical performance is better. Its overall performance and bending moment distribution are similar to those of a flat plate; , so it has a larger total structural height than the slab structure, and is more suitable for large-span and large-load situations; moreover, the rib beam of the two-way ribbed floor is a two-way lattice structure, because the slab span is small and the load is transmitted in both directions Th...
