Description

Light assembled side fascia

Technical Field

The utility model relates to an assembled side fascia field, it is specific, a light assembled side fascia.

Background

With the development of modern industrial technology, the house can be manufactured in batches and in a set manner like machine production, factory prefabrication and field installation and assembly are realized, the field operation construction period can be greatly saved, the construction quality precision is improved, the field wet operation strength is reduced, energy conservation and environmental protection are facilitated, the field material waste can be reduced to a certain extent, and the house is suitable for large-area popularization and application. However, for traditional fabricated concrete external wall panels, the self weight is great, the production and transportation cost is high, the development of fabricated external wall panels is always restricted by the problems of high construction cost and the like, although light fabricated external wall panels are also available in the market in recent years, the framework of the fabricated concrete external wall panels still mainly adopts steel as a support system, under the premise of ensuring the strength performance of enough wall panels, the self weight of the wall panels is still large, in the production and manufacturing process, the steel mesh frame is complex to process, the cost is high, the production efficiency is low, because the metal material is influenced by the temperature, the contraction and expansion deformation coefficients are large, when the steel mesh frame is poured on the inner side of the wall body, the profile steel framework is easy to separate from the wall body filling aggregate, and great potential safety hazards exist.

The existing wallboard technical products are mainly divided into two categories, one is a pure light concrete filled wallboard, the product is mainly applied to a frame structure filled wall, the product adopts a steam curing technology or a cement natural foaming process, in order to meet the requirement of the protective strength of an outer wall, the product thickness is generally designed to be thicker, and a double-layer steel wire mesh is arranged in the product due to the poor shear strength of a cement product. The other is a light steel skeleton wallboard, which is characterized in that light steel keels are used as main stressed components of the wall body, gaps among the keels are filled with light cement aggregate, and in order to meet the strength requirement of the external wallboard, the technology is generally designed to use larger steel, and usually adopts thin-wall section steel for light weight treatment.

The technical defects of the existing products mainly comprise: 1. for a product adopting lightweight cement aggregate as a main stress member, the cement product has poor bending resistance and breaking resistance, so the thickness is generally thicker in the application process of the outer wall, the self weight is very large, the installation difficulty is high, and the product is very easy to break in the transportation, installation and transportation processes. 2. For the product adopting the light steel keel as the main stressed member, in order to meet the requirement of the strength performance of the outer wall, the steel consumption of the steel skeleton is generally designed to be larger, and because the steel has higher elasticity, thermal expansion and cold contraction performance and smooth surface, the steel and the filling aggregate are easy to crack under the action of temperature difference or external force, thereby causing hidden quality trouble. 3. In the production process of products, because the outer wall engineering wallboard has more sizes, the steel keel needs to be welded and assembled according to the size of the wallboard, the production efficiency is low, and the potential safety hazard is large. 4. Due to the high conductivity of metal materials and excessive steel consumption, the effects of sound insulation, heat insulation and the like of the building outer wall are influenced, and the development of energy conservation and emission reduction in the building market is not facilitated.

The utility model discloses to prior art's not enough, provide one kind and adopt plasticity light skeleton, replace current light gauge steel as bearing structure, reduced the cost of manufacture and the production efficiency of wallboard by a wide margin, also greatly reduced the product dead weight, improve the installation effectiveness, have important promotion and promotion effect to the energy saving and emission reduction of building market.

Disclosure of Invention

A light fabricated external wall panel comprises a net-shaped framework 1 and filling aggregate 2, wherein the net-shaped framework 1 is formed by cross-connecting sheet-shaped separation supporting plates and is of a net-shaped structure; the filling aggregate 2 fills the gaps 10 of the grid formed by the net structure of the net framework 1.

Optionally, the filling aggregate 2 is lightweight cement aggregate.

With this technique, the aforementioned problems can be effectively solved.

The utility model discloses utilize toughness higher and have certain tensile strength's plastics or thin-walled steel plate as the skeleton brace. In order to meet the structural stability of the material framework serving as a supporting structure in the using process and improve the mechanical properties of the material such as compression resistance, bending resistance and the like, the material is designed into a small cavity structure in the shape of a square grid, a honeycomb shape or a cylinder, and the like. Considering because of the independent cavity cuts apart the disconnection problem with wallboard filler aggregate, lateral wall reservation recess or cavity about the net to realize that aggregate intercommunication each other between the cavity improves wallboard overall stability, has also improved the convenience of production pouring greatly. When the engineering plastic is used as the keel framework, the thermal conductivity is low and is less than 1% of that of a steel material, so that the stability of the framework and the filling aggregate in the wall body after pouring is high, deformation and cracking are not prone to occurring, and the product quality is greatly improved. The utility model discloses in the application, can be according to wall structure requirement and atress direction characteristics, to skeleton net density, the optimization adjustment of wall thickness satisfies different wall body intensity designing requirements. In the production process of the aggregate filling product, the framework at the edge of the wallboard can also play a role in positioning the die, and the aggregate can be directly filled after the framework is firmly positioned, so that the production efficiency of finished products is greatly reduced.

For solving the diversity problem of wallboard size, also can cut into a plurality of standard units with the grid skeleton with reference to building modulus commonly used with its design, each unit plate adopts to piece together to insert the connection, finally splices into different wallboard size specification, can practice thrift the die sinking cost greatly, improves production efficiency.
