Composite building supporting piece and manufacturing method thereof

Abstract

The invention belongs to the technical field of building materials and discloses a composite building supporting piece and a manufacturing method thereof. The core body is combined with a metal shell, and the supporting piece has the rigidity of metals, also has the characteristics that the wood can be sawed, drilled, nailed and fixedly connected by using nails or bolts, can be corrosion-resistant and moisture-proof and is high in stability, difficult to deform, safe, reliable and light in weight. The overall quality of the building supporting piece is lightened, the construction safety is further guaranteed, and the supporting piece is simple in manufacturing process, high in operability, green and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of building materials, in particular to a composite building support and a manufacturing method thereof. Background technique [0002] The construction industry is an important material production sector of the national economy, and it is closely related to the development of the entire country's economy and the improvement of people's lives. China is in the transitional stage of development from a low-income country to a middle-income country, and the construction industry is growing rapidly and contributing a lot to the growth of the national economy. Since 1978, the scale of the construction market has continued to expand, the output value of the domestic construction industry has increased by more than 20 times, and the proportion of the added value of the construction industry in GDP has increased from 3.8% to 7.0%, becoming an important force driving the rapid growth of the national economy. With the ...

Building timber is an essential building material in building formwork construction. At present, the general building timber is sawn into square strips of certain specifications and shapes, which play a supporting role in building formwork construction. However, wood has some inherent The shortcomings, such as poor moisture-proof and anti-corrosion effects, are easy to be damp and damaged during use, and the rigidity is reduced, which brings hidden dangers to safety. Therefore, each wooden square has to be treated as waste after several consecutive uses, wasting a lot of wood, and the local economy. Not environmentally friendly; and the wood is flammable, especially when stacked in large quantities, there is a fire hazard
