Description
Technical Field
The utility model relates to a building technical field particularly, relates to a prefabricated assembled composite wall panel.
Background
Assembled composite wall panels are now widely used in the construction industry, and three types of composite sandwich wall panels, semi-composite sandwich wall panels, and non-composite sandwich wall panels are now commercially available (see fig. 1a-1 c). For the combined sandwich wall board, the inner leaf wall board and the outer leaf wall board are generally designed to bear force together, so that the combined sandwich wall board has better economy, for the non-combined sandwich wall board, the outer leaf wall board is only used as a protective layer and is not combined with the inner leaf wall board, the dead weight of the outer leaf wall board is completely born by the inner leaf wall board, the outer leaf wall board basically does not participate in the stress distribution of the inner leaf wall board, the stress and temperature deformation behaviors of the inner leaf wall board and the outer leaf wall board are completely independent, and the semi-combined sandwich wall board is a form between the inner leaf wall board and the outer leaf wall board.
In terms of wall materials, the materials used in the prior sandwich wall panels still mainly comprise common concrete, and because the common concrete external wall panels have the defects of large mass, poor crack resistance, poor heat preservation and the like, the novel concrete represented by aerated concrete and ceramsite concrete is gradually replacing the common concrete for the sandwich wall panels. The sandwich insulation board made of materials such as a thin-wall concrete rock wool composite wallboard, a concrete polystyrene composite wallboard, a concrete expanded perlite composite wallboard and the like in the market at present is common concrete, and compared with the common concrete insulation board, the sandwich insulation board made of materials such as an aerated concrete wallboard, a vacuum extrusion forming fiber cement board (ECP), a rice hull mortar light energy-saving board and the like is remarkably improved in working performance.
From the perspective of heat insulation materials, the heat insulation materials of the sandwich board can be divided into organic and inorganic materials, the inorganic heat insulation materials mainly comprise foam concrete and rock wool products, most of the inorganic heat insulation materials are non-combustible materials, but the inorganic heat insulation materials are expensive and difficult to prepare, and the heat insulation performance of the inorganic heat insulation materials is reduced after the inorganic heat insulation materials meet the tide.
From the perspective of the pull, the sandwich panel pull can be classified as a metal pull, a non-metal pull. In view of the reliability of the bond between the three-layer construction of the sandwich panel, metal tie members are commonly used (see fig. 2a-2 d), however, metal tie members have some thermal conductivity and tend to create thermal bridges and thus heat losses. In the 80 s of the 20 th century, high-strength composite materials were developed, and tie bars such as GFRP (glass fiber composite), BFRP (basalt fiber composite), CFRP (carbon fiber composite), and AFRP (aramid fiber composite) were produced because of their characteristics of high strength, good toughness, low thermal conductivity, and the like.
The common composite wall board and wall material for the outer wall has poor bonding force, some of the materials are even not bonded, and the materials are generally connected through a pulling piece. The problem that once the composite external wall panel is continuously subjected to external force, such as wind load, the situation that the tie member is loosened and fails can be caused. The appearance of the outer vertical surface is influenced if the safety is light, people are injured if the safety is heavy, and the potential safety hazard is not ignored.
