Modular large wall board, and manufacturing method and application thereof

Abstract

The invention relates to a modular large wall board, and a manufacturing method and application thereof, belonging to the field of building materials. The board is mainly used for walls of buildings like workshops, storehouses and hangars. The board comprises a hoisting hole, a window frame, surface layers, a heat-insulation layer, and first to fourth edgings, wherein the first and second edgings are located at the left and right ends of the board respectively and are male and female structures which can be assembled respectively; the third and fourth edgings are located at the upper and lower ends of the board respectively; the hoisting hole is located in the first and second edgings and transversely passes through the whole board; and the heat-insulation layer is prepared from biological straw, cement and cotton felt, the biological straw and the cement are integrally arranged to form straw cement, and the cotton felt are adhered on two sides of the straw cement. The board provided by the invention has the advantages of great strength, light weight, heat insulation performance, noise-reducing performance, low cost and capacity of reducing environmental pollution.

Description

technical field [0001] The invention belongs to the field of building materials, and mainly relates to a large plate used for building walls such as workshops and hangars. Background technique [0002] Our company (Shandong Yibang Energy Technology Co., Ltd.) is a high-tech company dedicated to the research and development and production of high-tech new building materials. At present, the company has developed a series of panels that can be factory-produced and modularized for rapid construction. These panels It can be directly assembled into building walls or roofs, and there is no need for wall decoration after completion, and the resulting building has very good thermal insulation, sound insulation, and seismic performance. At present, these panels have been actually used in our company's office building and production workshop. [0003] Among the boards that have been developed, there is no large-scale board dedicated to building walls such as factory buildings and han...

Problems solved by technology

[0004] According to the research of Ralph Pudd, a scientist at the University of Bonn in Germany ("Science and Technology Daily" 2002-4-22, 4th edition), the reed in our country is an ideal building material, which not only has good heat insulation and sound insulation effects, but also Moisture-proof; in addition, reeds grow fast, can grow 5 centimeters per day, generally can grow to 3 to 4 meters, 1 hectare of reeds can build an ecological house, and reeds are easy to plant, only need a small amount of fertilizer, no pesticides, from From an ecological point of view, every hectare of Chinese reed planted can absorb about 30 tons of carbon dioxide (equivalent to the emission of a heavy truck driving 150,000 kilometers); currently, reeds are mainly used in building materials to make reed cement bricks, However, although this brick is impeccable as a roofing material, its stability as a load-bearing wall is not good

[0005] In addition, in addition to reeds, the annual output of other biological straws in my country is also very large. In recent years, due to the lack of corresponding utilization channels, a large amount of straws have been burned on the spot, causing serious air pollution
