Problems solved by technology

[0005] At present, most of the concrete materials used in building construction, especially wall construction, are poured in the form of traditional concrete or foamed concrete and steel bars. In order to ensure the strength of concrete, the amount of cement is more. The density and strength of foamed concrete also seriously affect the pouring stability, and even cause the mold to collapse
There are few studies on the strength, anti-corrosion, antibacterial and impact resistance of the completed buildings, and the comprehensive performance needs to be improved

preparation example 1

[0111] The preparation method of the modularized building insulation material comprises the following steps:

[0112] (1) get the cumene hydroperoxide of 2 weight parts, be dissolved in the distilled water of 20 weight parts at normal temperature, get the first initiator solution;

[0113] (2) Take 8 parts by weight of polyvinyl alcohol, dissolve it in 18 parts by weight of distilled water at normal temperature, add 5 parts by weight of tricalcium phosphate to the above solution, and ultrasonically for 10-20 minutes to obtain a stable dispersion;

[0114] (3) get the sodium dodecylbenzenesulfonate of 3 weight parts, be dissolved in the distilled water of 12 weight parts at normal temperature, obtain emulsion;

[0115] (4) 4.5 parts by weight of styrene, 0.5 parts by weight of DMAE-BC and 0.6 parts by weight of foaming agent are added to the first initiator solution of 4.4 parts by weight of step (1), and then 6.2 parts by weight of step (2) Disperse the stable liquid and 5 pa...

preparation example 2

[0125] The preparation method in which the antibacterial agent is added to the polystyrene building material in a blending manner comprises the following steps:

[0126] (1) Take 8 parts by weight of polyvinyl alcohol, dissolve it in 18 parts by weight of distilled water at normal temperature, add 5 parts by weight of tricalcium phosphate to the above solution, and ultrasonically 10-20 minutes to obtain a stable dispersion;

[0127] (2) get the sodium dodecylbenzenesulfonate of 0.6 weight part, be dissolved in the distilled water of 12 weight parts at normal temperature, obtain emulsion;

[0128] (3) get the cumene hydroperoxide of 2 weight parts, be dissolved in the distilled water of 20 weight parts at normal temperature, obtain the first initiator solution;

[0129] (4) Get 4.5 parts by weight of styrene and 0.5 parts by weight of DMAE-BC, add 22 parts by weight of distilled water, add 0.6 parts by weight of foaming agent, and stir evenly to obtain antibacterial modified po...

preparation example 3

[0139] In this preparation example, except that the antibacterial agent is methacryloyloxyethyl-n-hexadecyl-dimethylammonium bromide (DMAE-CB), other preparation methods and reagent consumption are the same as those of preparation example 1.

Abstract

The invention discloses a building construction method. The method comprises the following steps: (1) preparing a polystyrene modular building insulation material; (2) preparing gelled foamed concrete; (3) pouring the gelled foamed concrete into the molded polystyrene modular building insulation material to form a building body. The building construction method adopts modular molding, is simple inoperation, saves the cement, and simultaneously improves the antibacterial property, impact resistance, gelling property, flame retardance and corrosion resistance of the building structure.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a method for building construction. Background technique [0002] With the rapid development of urbanization, the demand for construction of various buildings is increasing rapidly, including more and more buildings such as residential buildings, office buildings, industrial parks and public service places. With the development of science and technology, building energy-saving projects become possible. The current building energy-saving projects that are widely used are to improve the thermal insulation performance of buildings and reduce energy consumption through the selection and design of building materials. Concrete exterior wall insulation is a technology that is widely used, and this insulation layer includes cast-in-place and post-installation construction methods. [0003] Patent CN201710209110.2 provides a concrete pouring method for concrete thermal insulation curt...
