構件預埋件分類

Component embedded parts classification

1、鍍鋅扁鋼預埋件：規(guī)格依據(jù)構件分量巨細確認，一般鍍鋅扁鋼規(guī)格：長40mm、寬30mm、厚3mm，間隔500mm，扁鋼鉆孔選用膨脹螺栓銜接。

1. Embedded parts of galvanized flat steel: the specification is confirmed according to the component size. General specifications of galvanized flat steel: length 40mm, width 30mm, thickness 3mm, interval 500mm. Expansion bolts are used to connect flat steel drilling.

2、預埋件形式分為外探、內探、直探、暗件，與墻體直接錨固或與裝置好的鋼架用螺栓銜接。

2. The embedded parts are divided into external exploration, internal exploration, direct exploration and concealed parts, which are directly anchored with the wall or connected with the steel frame with bolts.

銜接方法

Cohesion method

膨脹螺栓：一般在有外墻保溫（苯板）不宜施焊的，須選用膨脹螺栓銜接固定，脹栓長度、直徑以構件分量巨細確認。

Expansion bolt: generally, expansion bolt shall be used to connect and fix the external wall insulation (benzene plate) which is not suitable for welding, and the length and diameter of expansion bolt shall be confirmed by the component size.

墻體

wall

1、混凝土：扁鋼預埋件鉆孔用膨脹螺栓裝置。一般鉆孔間隔門窗洞口邊緣不應小于100mm，特殊情況此間隔應按實際確認，避免鉆孔遇混凝土主筋或將邊角打裂。

1. Concrete: expansion bolt device for drilling flat steel embedded parts. Generally, the interval between drilling holes shall not be less than 100 mm at the edge of door and window openings. In special cases, the interval shall be confirmed according to the actual situation to avoid the drilling hole meeting the main concrete reinforcement or cracking the corners.

2、空心磚：墻體為圍護結構，不承重，一般不宜直接選用脹栓裝置，應選用將固定預埋件處空心磚灌實后用脹栓裝置或鋼構裝置計劃。
