构件预埋件分类

Component embedded parts classification

1、镀锌扁钢预埋件：规格依据构件分量巨细确认，一般镀锌扁钢规格：长40mm、宽30mm、厚3mm，间隔500mm，扁钢钻孔选用膨胀螺栓衔接。

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、预埋件形式分为外探、内探、直探、暗件，与墙体直接锚固或与装置好的钢架用螺栓衔接。

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.

衔接方法

Cohesion method

膨胀螺栓：一般在有外墙保温（苯板）不宜施焊的，须选用膨胀螺栓衔接固定，胀栓长度、直径以构件分量巨细确认。

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.

墙体

wall

1、混凝土：扁钢预埋件钻孔用膨胀螺栓装置。一般钻孔间隔门窗洞口边缘不应小于100mm，特殊情况此间隔应按实际确认，避免钻孔遇混凝土主筋或将边角打裂。

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、空心砖：墙体为围护结构，不承重，一般不宜直接选用胀栓装置，应选用将固定预埋件处空心砖灌实后用胀栓装置或钢构装置计划。

2. Hollow brick: the wall is an enclosure structure, not load-bearing, and it is generally not suitable to directly select expansion bolt device. The expansion bolt device or steel structure device plan shall be selected after the hollow brick at the fixed embedded parts is filled.

3、有时选用穿透墙体的预埋件，此种计划北方地区简单产生冷桥，有必要经甲方同意并做好保温处理。

3. Sometimes, the embedded parts penetrating the wall are selected. In this kind of plan, the cold bridge will be generated in the north area, so it is necessary to get the consent of Party A and do a good job of heat preservation.
