Composite wall body with light steel-wood mixing keels and implementation method thereof

Abstract

The invention discloses a composite wall body with light steel-wood mixing keels and an implementation method thereof. The composite wall body comprises cold-formed thin-walled structural steel, cork boards, self-tapping screws and light weight boards which are subdivided. The cold-formed thin-walled structural steel comprises two subdivided parts along the central axis of a web of a cold-formed thin-walled lipped channel, steel keels of the mixing keels are formed, and the two parts are placed at the two ends of a cross section of the wall body in the height direction correspondingly; the number of the cork boards is two, wooden keels of the mixing keels are formed, and the cork boards are placed nearby the central axis of the web of the cold-formed thin-walled lipped channel; the cork boards and the cold-formed thin-walled lipped channel are connected to be a whole through the self-tapping screws; and the light weight boards are hung on flanges of the cold-formed thin-walled lipped channel of the two sides of the mixing keels. The composite wall body with the light steel-wood mixing keels has the characteristics that the heat preservation and thermal insulation performance is good, the bearing capacity is high, the weight is light, and energy conservation and environmental protection are achieved. In addition, when the keels cannot meet the requirement for building heat preservation or mechanical property, the keels can be still used after the corresponding parts are changed, and the flexibility is high.

Description

technical field [0001] The invention relates to the heat transfer performance and mechanical properties of a composite wall in the field of civil engineering, and specifically refers to a composite wall made of a light steel-wood hybrid structure as a keel and covered with an energy-saving and environmentally friendly light board, and belongs to the technical field of building construction. Background technique [0002] In China, traditional residential buildings have problems such as waste of land resources, high energy consumption, serious ecological damage, and poor comfort. In order to change the construction method of traditional houses, the country vigorously develops steel structures. With the continuous influx of foreign light steel structure enterprises and corresponding products and technologies, the cold-formed thin-walled steel structure system has developed rapidly. [0003] Cold-formed thin-walled steel structure houses are mainly composed of walls, floors, ro...

AI Technical Summary

Problems solved by technology

When thermal insulation keels are used for load-bearing walls, the number of opening rows is limited in order to ensure the vertical bearing capacity of the walls

Increasing the number of opening rows will reduce the mechanical properties of the light steel keel. Although it can meet the building insulation requirements in cold regions, it can only be used for non-load-bearing walls and cannot take advantage of the high strength and good ductility of light steel members. The economic benefit of this wall is reduced
