The size and specifications of stone pendants are introduced. Examples of dry stone pendants.

Stone product is an important building material product, but generally speaking, traditional stone is an ordinary plate. If you want to design and install them into a console or a furniture product later, you need to use other accessories, that is, the stone pendant I told you today. They come in many sizes and specifications, and there are also many concrete methods of stone pendants. You should learn from the experience and suggestions before buying, such as the above analysis and study.

A, stone pendant specifications

Picks used for dry hanging stone are different in length, and the materials of pendants are also different. The styles are pin type, back pin type, butterfly type, insert plate type and so on.

Stone dry hanging specifications:

1, thickness: 4mm-6mm.

2. Width: 40mm-60mm

3. Length: 40mm-180mm

4. Height: normal 15mm.

The specific value depends on the drawing requirements.

Second, the stone dry hanging materials

1, domestic stainless steel (high chromium): domestic dry-hanging commonly used materials and strips, cheap, generally recommended;

2, 304# stainless steel: imported large plate, matte and smooth surface, more expensive, mostly used in high-rise external walls and high-end hotels;

Three, stone dry hanging method

Pin type

That is to say, the pin and the pad are connected through the opening on the edge of the plate. This kind of dry hanging and its method were introduced from abroad in the mid-1980s, which laid the foundation for the domestic dry hanging award and was also the reference of the industry standard of the Ministry of Construction (JC830- 1998). This kind of inclined pin is stressed and the stress at the pin hole is concentrated. According to the existing project, the local cracking of stone at the stress concentration is labor-consuming, time-consuming and material-consuming. Now it has been gradually replaced by other methods.

Butterfly style

Butterfly [commonly known as upside down. The shape and method of this pendant are a little clumsy, which destroys the strength of the pendant (except high-quality stainless steel) during the processing and molding. During construction, due to the thickness and curvature of the inverted head, the groove phase must be widened, which is easy to damage the stone during installation. If the amount of glue used for processing the groove width is too large, its comprehensive cost will increase, so the technology will be slightly backward. The material requirements of pendants are not clear, which is not suitable for wide use.

Tie it in the back

This pendant was imported from Germany. Structure, as shown in figure 3. That is to say, the back of the stone is perforated, connected with the keel by money bolts, and the curtain wall dry-hanging system composed of post-cut anchor bolts and back bracing system can not be flexibly combined because of the mechanical anchoring structure, and can not solve the deformation problem caused by temperature difference. Because the adhesive directly determines the firm performance of the anchor, and the operation is complicated, machinery and anchor structure are not used in the borrowing scope.

Back hanging type

This pendant is made of 7075-phase Si-Mg alloy and has been patented in China, the United States, Britain, Japan and Taiwan Province Province. The construction method is fixed on the back of each plate, and there is no connection between plates, so there will be no uncertain stress accumulation and stress concentration caused by interconnection, and the stress is simple and clear, and the bending strength of plates can be fully utilized under normal use. This is a truly independent enterprise. Its material volume is light, and it has the characteristics of corrosion resistance, high temperature resistance, aging resistance and light volume through high-voltage electrostatic powder spraying. Accurate bearing capacity can be obtained through static calculation, thus controlling the failure state. When the main structure produces large displacement or temperature difference, it will not produce additional stress in the slab, which is suitable for high-rise buildings and Hangzhou exhibition buildings and embodies the design intention of flexible structure connection.

The above are examples of information about stone pendants, including the choice of size and specifications, as well as the use methods and skills of stone pendants. It can be seen that, generally speaking, traditional and basic stone materials are ordinary plates, which can not be directly put into use in the later stage, and need to be processed, including the selection of accessories and pendants. The pendant with the right size can play the role of connection and stability, and help stone products to play their own strong, beautiful and practical characteristics.
