Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with technical solutions and accompanying drawings.

[0024] The wall is formed by splicing wallboards; refer to figure 1 , the wallboard is a sandwich structure, using a plate made of ultra-high toughness cement-based composite material as the side panels 1, and filling the heat insulation and sound insulation materials between the side panels 1 to form a sandwich layer 2;

[0025] The mass ratio of the components of the mortar matrix of the ultra-high toughness cement-based composite material is cement: water: fine aggregate: fly ash: silica fume: granulated blast furnace slag: metakaolin = 1: (0.27~2.2): (0~ 3): (0~6.9): (0~0.3): (0~0.55): (0~0.4), where the maximum particle size of fine aggregate is not greater than 0.55mm, fly ash, silica fume, granulated blast furnace The weight of slag and metakaolin is not zero at the same time. In addition, chopped fibers are added to the mortar mat...

Abstract

The invention provides a sandwich insulating wall body based on an ultrahigh-toughness cement-based composite material and wall boards. The wall body is formed by splicing the wall boards; the wall board is of a sandwich structure, the boards made of the ultrahigh-toughness cement-based composite material are used as two side-surface boards; heat-insulating and sound-insulating materials are filled between the two side-surface boards to form a sandwich layer. The wall board provided by the invention integrates multiple functions and has the functions of thin walls, crack resistance, permeability resistance, impact resistance, heat insulation, sound insulation, vibration resistance, energy dissipation and the like; and the prefabricated wall board not only can be used as the external wall of a structure system, but also can be used as an internal partitioning wall. The wall body provided by the invention can be widely applied in building structures in various complex terrains and special environments, thus having a wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of new wall materials, and in particular relates to a sandwich insulation wall and wallboard based on ultra-high toughness cement-based composite materials. Background technique [0002] Natural disasters such as earthquakes, typhoons, and floods often cause serious damage to building structures, especially for building exterior wall panels, which are seriously damaged due to direct earthquake, horizontal wind load, and flood impact. Post-disaster maintenance of exterior wall materials The cost is very high. In order to realize the integration of utility and benefit, and to give full play to the bearing capacity, stability and ductility of structural components on the basis of structural design principles, attention must be paid to the selection of building materials. Wall materials are the main part of building materials, and their properties in various aspects directly affect the overall performance of th...
