Omega-type-spliced-keel composite wall
A composite wall and keel technology, applied in the direction of walls, building components, buildings, etc., can solve the problems such as the inability to exert the strength of light steel components, reduce the mechanical properties of light steel keels, and limit the number of rows of openings. Ease of components and improved load-carrying capacity

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

Embodiment
[0026] see Figure 1 to Figure 3 As shown, an Ω-shaped split keel 1-type composite wall of the present invention includes three parts: steel structure keel 1, self-tapping screw 3, and outer cladding wallboard 2. In the figure, the side marked with 4 is outdoor, and the side marked with 5 is indoor.
[0027] The above-mentioned steel structure keel 1 includes two Σ-shaped cold-formed thin-walled steel members 11, the type of which depends on the vertical load and horizontal load borne by the wall, and the steel material is Q235 steel or Q345 steel. Combining two Σ-shaped steel materials 11 back to back into an Ω-shaped steel structure keel 1 can improve the stability of the keel 1 and further increase the bearing capacity of the wall.
[0028] Above-mentioned self-tapping screw 3 is made up of three parts of drill bit, screw tap and screw thread. Drills are mainly used to drill holes on connectors, taps are used to process threads on holes, and the main function of threads i...

The invention discloses an omega-type-spliced-keel composite wall. The omega-type-spliced-keel composite wall comprises a steel structure keel and external wrapping wallboards, and the steel structurekeel is formed by splicing two sigma-type steel materials; webs of the sigma-type steel materials have incurve parts bending inwards, the webs of the two sigma-type steel materials abut against eachother, and the two sigma-type steel materials are locked and fixed in the state that the positions of the incurved parts are opposite; the side face of the steel structure keel is internally connectedto the inner sides of the two external wrapping wallboards, and the steel structure keel supports the external wrapping wallboards. The omega-type-spliced-keel composite wall is good in heat preservation and insulation performance, high in carrying capacity, light, high in strength and convenient to construct.
Description
technical field [0001] The present invention relates to the technical field of building construction in civil engineering, and in particular to a compound wall composed of double-leg Σ-shaped web-plate-stiffened cold-formed members back-to-back assembled into an "Ω"-shaped assembled member as a keel, and covered with energy-saving and environmentally friendly light-weight boards body. Background technique [0002] Steel structure buildings have the advantages of light weight, high strength, fast construction speed, energy saving and environmental protection, and high comprehensive benefits. They are in line with my country's development strategy of building a "resource-saving" and "environment-friendly" society. The selection of supporting walls in steel structure buildings is often the key to its further popularization and application. The traditional block wall is heavy, on-site wet operation and labor-intensive operation methods do not meet the development requirements o...
