Description

A kind of glued wood-concrete composite floor

technical field

The utility model relates to the technical field of building materials, in particular to a glued wood-concrete composite floor.

Background technique

With the advancement of modern urbanization, steel and concrete are becoming the main building materials. However, the construction industry dominated by steel structures and concrete structures has always been a major energy consumer and polluter. In order to control pollution, protect scarce resources and energy, and maintain the stable and sustainable development of the national economy, it is imminent to use new energy-saving, eco-friendly, high-performance, and low-cost new building materials. In addition, the building industrialization of standardization of architectural design, industrialization of component production, mechanization of construction process and scientific combination management has increasingly become the focus of my country's promotion of green buildings.

Wooden structure has a long history and is one of the earliest forms of architectural structure adopted by human beings. As early as 3,000 years ago, the wooden structure frame system appeared in the three ancient civilizations of China, Egypt and Greece. After a long period of time, the wooden structure has been widely used due to its excellent structural performance and aesthetic value. . The glued wood components are composed of dimension timber boards, which are connected at the ends to form a certain length, and then glued together with an adhesive to make the required glued components. Through the production of glued wood, the short materials after harvesting and wood processing, as well as the small-diameter timber of plantation forest tending and thinning, can be shortened into long, narrow into wide, and thin into thick. In addition to the characteristics of ordinary wood structures, such as beautiful and comfortable, energy-saving and environmentally friendly, thermal insulation, and good seismic performance, the glulam structure also has its unique performance advantages: 1. Reasonable and optimized use of wood; 2. Industrial production; 3. Various structural forms . The unique charm and wide applicability of glulam itself make glulam structures widely used all over the world.
