建筑幕墙依据不同的面板材料分为玻璃幕墙、金属幕墙和石材幕墙三大类，无论哪类幕墙，其承载结构体系与建筑主体结构的连接，通常都是通过预埋件或后加锚固件来实现的。幕墙除了承受自重荷载外，还要承受风力、地震等荷载的影响，因此预埋件与建筑主体结构的连接是否可靠耐久，直接关系到幕墙的结构安全与使用寿命。

Building curtain wall is divided into three categories: glass curtain wall, metal curtain wall and stone curtain wall according to the different panel materials of the building curtain wall. No matter which kind of curtain wall, the connection between the bearing structure system and the main structure of the building is usually realized by using embedded parts or later adding anchor parts.In addition to bearing the self-weight load, the curtain wall should also bear the influence of wind, earthquake and other loads. Therefore, whether the connection between the embedded parts and the main structure is reliable and durable is directly related to the structural safety and service life of the curtain wall.

那什么是预埋件？

预埋件就是预先安装在隐蔽工程内的构件.是在结构浇注时安置的构配件，用于砌筑上部结构时的搭接。以利于外部工程设备基础的安装固定。铁路预埋件是混凝土浇筑前预先放好的金属构件，用来连接螺栓或弹条等地面紧固装置的地下金属配件。

So what is embedded parts?

The embedded parts are the components pre-installed in the concealed works. It is the structure and accessories placed when the structure is poured for erecting the superstructure.To facilitate the installation and fixation of the external engineering equipment foundation.Railway embedded parts are metal components preplaced before concrete placement to connect underground metal fittings for ground fastening devices such as bolts or bullet strips.

热镀锌是一种有效的金属防腐方式，主要用于各行业的金属结构设施上。是将除锈后的钢件浸入500℃左右融化的锌液中，使钢构件表面附着锌层，从而起到防腐的目的。热浸锌是将除锈后的钢构件浸入600℃左右高温融化的锌液中，使钢构件表面附着锌层，锌层厚度对5mm以下薄板不得小于65μm，5mm及以上厚板不小于86μm。从而起到防腐蚀的目的。

Thermal galvanizing is an effective metal anticorrosion method, mainly used in metal structure facilities in various industries.It is to rust the steel parts into about 500℃ of melted zinc liquid, so that the steel members surface attached zinc layer, so as to play the purpose of corrosion.Hot dip zinc is the removal of steel members into about 600℃ of high temperature melted zinc liquid, so that the steel member surface attached to the zinc layer, zinc layer thickness below 5mm thin plate should not be less than 65 m, 5mm and above thick plate shall be not less than 86 m.Thus to play the purpose of corrosion prevention.
