A precast concrete shear wall is also called a "sandwich wall panel". It refers to an integral component formed by sandwiching insulation material between two layers of concrete wall panels. It is generally composed of inner panels, insulation panels, and outer panels, forming a sandwich-like structure. The inner and outer panels are reinforced concrete materials, and the middle is made of insulation material with a fire resistance grade of B1 or B2. The tensioning parts are generally FRP high-strength composite materials.
1. Preast concrete shear walls produced through standardized and modular production have uniform concrete vibration, compactness, stable quality, high precision, consistent specifications, and controllable size, which not only facilitates the later installation and connection, improves the integrity and strength of the building, but also indirectly improves the construction speed and makes the appearance beautiful and consistent. During the hoisting process, the position of the components is easier to control, which is conducive to accurate installation and anchoring.Use shuttering magnet to fix the mold table
2. When producing concrete shear walls, the inner page plate, insulation layer and outer page plate are formed at one time, and connected to form a whole through reliable connectors, with excellent integrity. There is no need to do exterior wall insulation, the construction difficulty is reduced, and the insulation layer and exterior finish have the same lifespan as the structure. The thickness of the inner and outer page plates can be adjusted. Due to the improvement of the overall performance, the service life of the building is improved, the gap is small, and the probability and strength of steel bars being corroded are reduced.
3. The exterior wall can be made of real stone paint, tiles or other decorative materials. The exterior finish can also be made into concave and convex, stripes or various patterns to diversify the exterior finish and simplify the complicated exterior wall decoration process in the later stage.
4. In terms of cost, due to the high precision of the inner page plate, plastering can be eliminated to achieve the purpose of cost saving; the use of prefabrication can greatly reduce the number of on-site formwork; the number of on-site workers can be greatly reduced; the use of a non-external frame solution saves the cost of the external scaffolding, and the safety factor is also greatly improved.
This prefabricated concrete shear wall is particularly practical for ordinary people to build houses. It has a fast construction speed and high precision, which can make the house structure stronger; the one-piece design does not require external wall insulation, the insulation layer has a long life, and it is warm in winter and cool in summer, which also saves the cost of later maintenance; the external wall can be directly made into various styles such as real stone paint, tiles, patterns, etc., which are beautiful and face-saving; at the same time, there is no need for plastering, reducing formwork and labor, and no external scaffolding, which not only reduces the cost of building a house, but also improves construction safety. You can live in a solid, beautiful and comfortable house for less money.
