How to Optimize the Design of Modern Architectural Stone Curtain Wall-WJW Aluminum Supplier Aluminum Industry

The dry hanging lab wall on the outer wall is highly respected with its unique natural and solemn and gorgeous color style and appearance. It not only effectively prevents defects such as stone wall alkali, discoloration, empty drums, and falling off caused by traditional decorative stone wet pulp, but also has short construction cycle, high installation accuracy, good decoration effect, reducing the weight of the building, improving the resistance of seismic performance, etc. Advantages, especially the characteristics of strong installation capacity and safety use. It has been widely used in the decoration of the exterior wall of the building and is favored by the owners and architects.

With the rapid development of the construction industry, the building curtain wall is the combination of building technology, function and architectural art in the surrounding structure of the building. It is an advanced external decoration of today's architecture.

Stone is an ancient building material. The stone has become one of the preferred materials for outdoor decoration with its noble, elegant, solid durability, stability and solemn, return to nature, and bring people's taste and return to nature.

This article briefly discusses the optimized design of stone curtain walls in modern buildings, with a view to helping related practitioners.

Foreword

The optimized design of modern architectural stone curtain walls usually determines the accurate size of stone, color, materials, seam materials, etc. It also draws detailed stones vertical size diagrams and node details of each complex part, and then calculate the corresponding mechanical intensity according to the requirements of weight, size and earthquake resistance, wind pressure, etc., and determine the dry hanging method of the stone keel system. When determining the specific shape and processing size of dry hanging stones, accurate verification must be performed to ensure that it is unparalleled (especially when using the expensive imported stone), so as not to cause huge economic losses.

At present, the design unit usually only provides the facade mesh form and a small number of node diagrams of the facade of the curtain wall. The construction unit cannot be constructed according to the graph. Therefore, it is necessary to optimize the design of the slate and related dry hanging systems. The responsibilities of the unit.

Due to uneven technical level, many stone engineering does not even have corresponding mechanical computing and on -site test verification. The selection and determination of stone and dry hanging systems are based on daily construction experience. Due to insufficient strength or excessive strength, it is easy to cause material waste.

The optimized design of the stone curtain wall requires the calculation of the stone, the chosen dry hanging method, and the mechanical computing of the stone and the dry hanging system. The calculation results conducted on -site mechanical performance tests.

1. Select stone material

When optimizing the design, the design unit and construction unit shall cooperate with the designer's requirements for building effects such as curtain wall grid and material color, and cooperate with each other to provide the architect with various stone samples to help them determine the stone used as soon as possible.

According to stone data, we should pay attention to technical performance indicators such as the surface characteristics, color and texture of the stone.

Although the stone supplier provides the physical performance indicators of the stone, as a natural material, the physical properties of the stone have changed a lot, and it is necessary to re -determine it to establish corresponding design indicators for stone design.

2. Choose a dry hanging method

The dry hanging of the stone has several forms such as steel nail type, seam type, short groove type, and rear bolt type. The commonly used short groove type and rear bolt type.

In contrast, the cost of short slots is low, but the safety is not as good as the rear bolt type, and is usually used in occasions with the weight of the stone that is not too large or the safety factor is not too high; When the thickness of 30mm stone is>; 1.5m2) or the requirements for stone safety performance are high.

Third, the mechanical calculation of stone and dry hanging systems

First determine the load and action form of the curtain wall, then determine the dry hanging method of the stone, and then determine the calculation model of the slate, and then calculate the load value of the dry hanging system. Finally, according to the load value of the dry hanging system, the structural form of the dry hanging system and the specifications and sizes of the stems, joints, buried pieces, horizontal keels and vertical keels. The design of the stone and its dry hanging system should meet the requirements of the national standard "Metal Stone curtain Wall Engineering Technical Specification".
