Bidirectional truss combined board made from composite material and manufacturing method therefor

Abstract

The invention discloses a bidirectional truss combined board made from a composite material and a manufacturing method therefor. The combined board comprises a light steel skeleton, an upper surface layer, a light-weight aggregate concrete layer, an insulating and sound-isolating layer and a bottom surface layer. The insulating and sound-isolating layer is located on the inner side of the light steel skeleton, and the light-weight aggregate concrete layer is paved on the upper part of the light steel skeleton; the upper surface layer is paved on the light-weight aggregate concrete layer, and the upper surface layer is a transmitting hard shell aerogel insulating layer; the bottom surface layer is located on the lower surface of the light steel skeleton; the light steel skeleton has a light steel outer frame which is internally provided with a bidirectional light steel truss, the outer surface of the light steel skeleton is coated with a cement-based composite material, and hemmed holes are formed in the abdomens of light steel. The board disclosed by the invention effectively solves the fireproof, corrosion-resistant and sound-isolating problems of a steel structure, and has the advantages of circular economy, energy conservation, environmental-friendliness and prolongation of service lives of buildings.

Description

technical field [0001] The invention relates to the technical field of building materials and manufacturing, in particular to a composite bidirectional truss composite board and a manufacturing process thereof. Background technique [0002] At present, with the rapid development of the country's urbanization construction, China's construction scale ranks first in the world. The large-scale construction of buildings has caused environmental and resource problems. Ecology, energy saving, environmental protection, circular economy, and construction industrialization have become the sustainable important issues in the development strategy. In order to prolong the life of the building and facilitate the replacement and maintenance of filling bodies such as pipelines, it is necessary to innovate the building system of "CSI" (C is China, S is the support body Skelton, I is the filling body Infill) that separates the support body from the filling body. , "CSI" is a new building com...

Problems solved by technology

[0003] In addition, the discharge of fly ash in China has reached 540 million tons. Long-term stacking not only occupies a large amount of land, causing serious environmental pollution, but also causes a huge waste of resources. Further treatment is urgently needed to effectively recycle waste and develop a circular economy.

The construction industry is a large energy-consuming consumer. In 2010, it has reached 1.85 billion tons of quasi-coal. The energy consumption of heating buildings accounts for about 30% of the total energy consumption. Existing energy-saving and thermal insulation materials, such as: polystyrene board, polyurethane, extruded board, It has good thermal insulation performance, convenient operation, and low water absorption, but these materials have poor fireproof performance, and will produce toxic gases when burned, are easy to age, and have poor durability

[0004] The steel structure in the prior art has the problems of fire prevention, anti-corrosion, and poor sound insulation performance, which has been plagued by the steel structure industry in the construction industry, and is a key technology that needs to be solved urgently in the field of steel structure today.
