錨
(Anchor)
錨
定義：（1）在預加應力混凝土，用以鎖定在適當位置的強化鍵結，使保持受壓狀態；（2）在預鑄混凝土，為預鑄單元連接到建築物框架；（3）在樓板與牆壁，需連接到緊固的岩盤或鄰近結構，以防止上述樓板或牆在鄰近結構或岩盤結構的滑移。
鋼錨是用於澆鑄混凝土或硬固混凝土構件用於傳遞混凝土的負載。場鑄錨包括雙頭螺栓，帶鉤螺栓（J-或L型螺栓）和雙頭螺柱。後安裝錨包括膨脹螺栓，擴孔型錨栓，錨膠粘劑。使用錨膠粘劑的鋼構件包括螺紋桿，變形鋼筋，或外部變形的內螺紋鋼套管。錨固系統通常用來將一個結構的兩個部分連接在一起，或者把一個非結構構件連接到結構體。
Anchor
Definition: (1) in prestressed concrete, to lock the stressed tendon in position so that it will retain its stressed condition; (2) in precast-concrete construction, to attach the precast units to the building frame; (3) in slabs-on-grade or walls, to fasten to rock or adjacent structures to prevent movement of the slab or wall with respect to the foundation, adjacent structure, or rock.
An anchor is a steel element either cast into concrete or post-installed into a
hardened concrete member and used to transmit loads to the concrete. Cast-in
anchors include headed bolds, hooked bolts (J- or L-bolt), and headed studs.
Post-installed anchors include expansion anchors, undercut anchors, and
adhesive anchors. Steel elements for adhesive anchors include threaded rods,
deformed reinforcing bars, or internally threaded steel sleeves with external
deformations. Anchor systems are typically used to connect two parts of a
structure together or to connect a nonstructural item to the structure.
